Description

  The present invention relates to a sampling object extraction method using, for example, a sampling device that grips a sampling target disposed inside a substantially cylindrical housing and pulls it along the axial direction of the housing.

In recent years, electric motors are used not only in home appliances such as air conditioners but also in various products such as railway vehicles, hybrid vehicles, and electric vehicles.
For example, as an electric motor for a vehicle, as disclosed in Patent Document 1, a rotor (rotor) having a substantially annular stator (stator) and a permanent magnet that is arranged inside the stator and generates a strong magnetic force. Are housed in a housing.

Such a rotor of an electric motor is rotatably supported by a bearing. However, since wear and damage occur in the bearing due to deterioration over time, it is necessary to replace the bearing at an appropriate timing.
Therefore, various techniques that can easily replace the rotor bearing have been proposed.

  For example, in Patent Document 1, a cage-shaped first replacement jig is attached to a bearing bracket that supports a bearing assembly having a bearing. Thereafter, the joint shaft is inserted into the shaft support hole of the first replacement jig, and the tip of the joint shaft is fixed to the shaft portion of the rotor (rotor) to support the rotor.

  Then, after the bearing assembly is slid in the axial direction from the shaft portion of the rotor supported by the joint shaft, the second replacement jig composed of a pair of substantially semicircular members is mounted on the bearing bracket. Then, the shaft portion of the rotor is supported. In this state, the bearing assembly can be taken out without removing the rotor by removing the first replacement jig and the joint shaft.

  By the way, in recent years, rare earth magnets such as neodymium magnets are used as permanent magnets in electric motors of hybrid vehicles that are increasing in recent years. Since this rare earth magnet contains a rare earth element, so-called rare earth, recently, it has been promoted to recover and recycle the permanent magnet from the rotor.

  However, when the rotor is extracted from the stator as an object to be extracted, there is a problem that the rotor, which is also a heavy object, cannot be easily extracted because it is attracted to the stator or the like by the strong magnetic force of the permanent magnet.

JP 2013-223390 A

  In view of the above-described problems, an object of the present invention is to provide a sampling object extraction method that allows an extraction object to be easily extracted from a housing.

  The present invention relates to a method for extracting an object to be extracted using an extraction device for extracting an object to be extracted housed in a substantially cylindrical housing in an extraction direction along the axial direction of the housing, the opening of the housing being A sampling device installation step for bringing one end of the bottom structure in the sampling device into contact with the end and aligning the position of the object insertion hole formed in the bottom structure and the sampling target; The force-increasing mechanism unit that receives the operation of the operator that rotates the handle provided at one end in a predetermined rotation direction by the handle, and the gripping mechanism unit connected to the other end is moved in the pull-out direction as the handle rotates. And a forward path step in which a pair of gripping members of the gripping mechanism part inserted through the object insertion hole is brought into contact with the extraction object, and the handle is moved in the predetermined rotation direction. A gripping member separating step in which the force-increasing mechanism portion that has received the operation of the operator to further rotate the handle with the handle causes the pair of gripping members to separate with the rotation of the handle; and The force-increasing mechanism that has received the operation of the operator that rotates in the direction opposite to the rotation direction with the handle brings the pair of gripping members close together with the rotation of the handle, and moves the object to be extracted. The step of gripping and the force-increasing mechanism that has received the operator's operation to further rotate the handle in the reverse direction with the handle increases the input load to the handle and pulls in the pull-out direction. A return path step of converting the gripping mechanism portion that has converted into a load and gripped the object to be extracted in the extraction direction through the object insertion hole.

The extraction object may be a magnetic body that is attracted to peripheral components by magnetic force, for example, a rotor in an electric motor. Alternatively, it may be a heavy object that is not easily extracted, such as a rotating shaft equipped with a gear or a bearing.
For example, the force-increasing mechanism unit can be a mechanism unit that increases the force by a lever, a link, a gear, and a combination thereof, and converts an input load into a load in the pull-out direction.

From this invention, the extraction method of the extraction object can easily extract the extraction object from the housing.
Specifically, with the force-increasing mechanism that increases the input load, the extraction target object can be extracted with a small input load. For this reason, the extraction method of the extraction object can reduce the burden on the operator even if the extraction object is a heavy object, for example.

  Furthermore, since the increased input load is converted into a pulling load in the pulling direction, the pulling object extraction method can reliably move the pulling object along the pulling direction by the pulling load. Thereby, for example, even in the case of an extraction object that generates a strong magnetic force, the extraction object extraction method can easily extract the extraction object without being attracted to the surrounding metal parts.

  In addition, the operator's operation for rotating the handle in a predetermined rotation direction and the operator's operation for rotating the handle in a direction opposite to the predetermined rotation direction are received in this order, thereby The sampling method can continuously perform the forward path process, the gripping member separation process, the gripping process, and the return path process.

Thereby, the extraction method of the extraction object can extract the extraction object arrange | positioned inside a housing, without an operator releasing a hand from a handle.
Furthermore, since the extraction object can be extracted by the input load input by the operator who operates the handle, the extraction object extraction method can be performed without using a drive device or a power supply device that moves the gripping mechanism. The object to be extracted can be extracted.
Therefore, the sampling object extraction method can easily extract the extraction object from the housing.

  As an aspect of the present invention, when the gripping mechanism portion is inserted into the object insertion hole in the forward path step, a gap of an openable opening / closing lid that is mounted on the other surface of the bottom structure body at a predetermined interval is provided. And a biasing means provided on the bottom structure when the extraction object passes through the object insertion hole in the return path step, the step of inserting the pair of gripping members of the gripping mechanism portion. The step of closing the open / close lid opened by the object to be extracted can be provided.

From this invention, the extraction method of the extraction object can efficiently extract the extraction object.
Specifically, since the opening / closing lid is arranged so that a set of gripping members can be inserted, the method of extracting the object to be extracted can facilitate the alignment of the housing and the bottom structure.

Furthermore, since the opening / closing lid is closed by the biasing means after the object to be extracted has passed through the object insertion hole, the method for extracting the object to be extracted can prevent the opening / closing lid from being left open, and the operator can open and close it. The trouble of closing the lid can be saved.
In addition, for example, when the upper direction in the vertical direction is the drawing direction, the open / close lid can function as a mounting table on which the extracted object to be extracted is placed.

Furthermore, the opening / closing lid can function as a protective member that protects the housing and the like from the dropped extraction object in the unlikely event that the extraction object drops from the gripping mechanism.
Therefore, the extraction method of the extraction object can efficiently extract the extraction object by providing the bottom structure with an openable / closable lid.

  According to another aspect of the present invention, the forward step is the first forward step, the return step is the first return step, and the operator rotates the handle in the predetermined rotation direction after the first return step. The force-increasing mechanism that has received the operation by the handle moves the gripping mechanism in a direction opposite to the pulling-out direction as the handle rotates, so that the object to be pulled out contacts the opening / closing lid. The step of contacting the second forward step and the force-increasing mechanism unit that receives the operation of the operator further rotating the handle in the predetermined rotation direction by the handle, the set of grips as the handle rotates. A gripping member separating step for separating the member and an operation of the operator for rotating the handle in a direction opposite to the predetermined rotation direction are received by the handle with the rotation of the handle. Said pull It may comprise a second backward step of moving the gripping mechanism toward the direction.

According to the present invention, the sampling object sampling method can make the extracted sampling object safe and easily recoverable, and can easily start the first forward process.
Specifically, for example, when the upper direction in the vertical direction is the pulling direction, the method for extracting the object to be extracted is to place the extracted object on the opening / closing lid without releasing the hand from the handle. It is possible to release the object to be extracted.

  Alternatively, when the horizontal direction is the extraction direction, the extraction method of the extraction object can release the grasp of the extraction object without releasing the hand from the handle, for example, prepared in advance under the extraction object. Can be placed on a cushion or trolley.

Thereby, since the extraction method of the extraction object can continue the first outward process after the completion of the second return process, the extraction object can be extracted easily and continuously.
Therefore, the sampling object extraction method can safely and easily collect the extracted sampling object by the second forward path process, the gripping member separation process, and the second backward path process that are continued from the first return path process. It is possible to facilitate the start of the first outward path process as well as the state.

  As an aspect of the present invention, when the abutting member of the gripping mechanism that moves in the pulling direction abuts on a predetermined part in the pulling direction in the second return path step, the boosting mechanism is A pair of opening and closing links in which the main shaft member of the gripping mechanism portion is moved relative to the support member of the gripping mechanism portion supporting the member in the pulling direction, and the main shaft member is connected to the gripping member. The member can be provided with a step of bringing the pair of gripping members close by rotating the member in the pulling direction.

The predetermined portion can be, for example, a force-increasing mechanism part or a support frame that supports the force-increasing mechanism part.
According to the present invention, the method for extracting the object to be extracted can reliably close the set of gripping members without the operator releasing his / her hand from the handle.

  Specifically, in the second return path process, when the gripping mechanism portion releases gripping of the object to be extracted, for example, a set of gripping members is in a fully open state due to, for example, frictional resistance between the opening / closing link member and the main shaft member. May remain.

  Therefore, by bringing the contact member into contact with a predetermined part in the pulling direction, the method for extracting the object to be extracted easily closes a set of gripping members in a fully open state without releasing the hand from the handle. Can do.

Thereby, the sampling method of the sampling object can start the 1st outward path process more reliably after the 2nd return path process is completed.
Therefore, the method for extracting the object to be extracted is to close the set of gripping members securely without letting the operator release the hand by bringing the contact member of the gripping mechanism portion into contact with a predetermined part in the pulling direction. be able to.

  Further, as an aspect of the present invention, in the gripping member separating step, the force-increasing mechanism portion is opposite to the pulling direction with respect to the support member of the gripping mechanism portion that rotatably supports the set of gripping members. The main shaft member of the gripping mechanism portion is moved relative to the main shaft member, and the main shaft member rotates a pair of opening / closing link members connected to the gripping member in a direction opposite to the pulling direction. A step of separating a pair of gripping members, and in the gripping step, the force-increasing mechanism unit moves the spindle member relative to the support member in the pulling direction, and the spindle member is A step of bringing the set of gripping members close by rotating the set of opening / closing link members in the pulling direction can be provided.

  According to the present invention, the method for extracting the object to be extracted can grip the object to be extracted and release the grip without releasing the hand from the handle by the operator, and more efficiently extract the object to be extracted. be able to.

  Furthermore, when a set of gripping members is brought close to each other in the gripping process, a load in the pulling direction acts on the set of open / close link members. Can be easily maintained. Thereby, for example, when a load along the axial direction is added to the object to be extracted using a press machine, or compared with a case where the object to be extracted is grasped and extracted by a construction machine (so-called heavy machinery), The extraction method of the extraction object can prevent an excessive load from being applied to the extraction object.

For this reason, the sampling method of the sampling object can prevent the deformation of the sampling object. For example, when recovering the recovery object built in the sampling object, the recovery of the recovery object is hindered by the deformation of the sampling object. Can be prevented.
Therefore, the extraction method of the extraction object can easily extract the extraction object from the housing without damaging the extraction object.

  According to the present invention, it is possible to provide a sampling object extraction method that allows an extraction object to be easily extracted from a housing.

As shown in FIGS. 1 and 3, the bridge portion 22 is configured by fastening and fixing flat plate members having a substantially rectangular shape in front view in the width direction Y to the front surface and the rear surface at the upper end of the column portion 21.

  Furthermore, a carrying handle 23 extending toward the outside in the width direction Y is attached to the support base 20 in the vicinity of the upper end of the column portion 21. The transport handle 23 functions as a handle for the operator when the rotor extraction device 1 is moved.

  Further, as shown in FIGS. 1, 3, and 4, the force-increasing mechanism unit 30 can be expanded and contracted in the vertical direction by assembling a plurality of substantially belt-shaped link members having a predetermined thickness in the front-rear direction X. It has a pantograph shape. The force-increasing mechanism 30 is made of a nonmagnetic metal member such as an aluminum alloy.

  More specifically, the booster mechanism 30 can be deformed into a substantially rhombus state in front view (see FIG. 1) whose pantograph shape is long in the width direction Y and a substantially rhombus state in front view (see FIG. 4) long in the vertical direction. It is configured.

  As shown in FIG. 1, the force-increasing mechanism 30 includes a pair of input link members 31 having a pair of handles 31 a serving as a handle of the operator at one end and a pair of first link members connected to the lower end of the input link member 31. The connecting link member 32 includes a pair of second connecting link members 33 connected to the lower end of the first connecting link member 32, and a pair of end link members 34 connected to the lower end of the second connecting link member 33. .

  As shown in FIG. 1, the pair of input link members 31 intersect so that a pair of handles 31 a provided at one end are positioned outside the upper end in the width direction Y, and the intersecting portions are rotatably connected to each other as viewed from the front. It is configured in a substantially X shape. Hereinafter, the connecting portion of the intersecting portion in the pair of input link members 31 is referred to as a first intersecting connecting portion 31b.

  Further, the other end of the input link member 31 is rotatably connected to the upper end portion of the first connection link member 32. Hereinafter, the connecting portion between the input link member 31 and the first connecting link member 32 is referred to as a first connecting portion 35.

  In the input link member 31, the ratio of the linear distance from the first cross connection portion 31b to the handle 31a with respect to the linear distance from the first cross connection portion 31b to the first connection portion 35 is 1: 3. Forming.

  The pair of first connecting link members 32 intersects below the first intersecting connecting portion 31b, and are configured to have a substantially X shape when viewed from the front by rotatably connecting the intersecting portions. Hereinafter, the connecting portion of the intersecting portion of the pair of first connecting link members 32 is referred to as a second intersecting connecting portion 32a.

  Furthermore, the upper end portion of the second connection link member 33 is rotatably connected to the other end of the first connection link member 32. Hereinafter, the connecting portion between the first connecting link member 32 and the second connecting link member 33 is referred to as a second connecting portion 36.

  The first connection link member 32 has a first distance between the second cross connection portion 32a and the first connection portion 35, and a first distance between the second cross connection portion 32a and the second connection portion 36. It is formed so as to be substantially equal to the linear distance from the portion 31 b to the first connecting portion 35.

  The pair of second connection link members 33 is substantially the same as the first connection link member 32 except that the end link member 34 is connected to the other end, and thus detailed description thereof is omitted. In addition, the connection location of the intersection part in a pair of 2nd connection link member 33 is hereafter called the 3rd cross connection part 33a, and the connection location of the 2nd connection link member 33 and the terminal link member 34 is 3rd connection below. Part 37.

  The pair of end link members 34 are rotatably connected to each other at the other end with a gripping mechanism 40 (a main shaft member 41 of the gripping mechanism 40 to be described later) sandwiched below the third cross connection portion 33a. It is configured in a substantially V shape. Hereinafter, the other ends of the pair of end link members 34 and the connection portion of the gripping mechanism portion 40 are referred to as a fourth cross connection portion 34a.

  The end link member 34 is formed so that the linear distance from the fourth cross connection portion 34 a to the second connection portion 36 is substantially equal to the linear distance from the second cross connection portion 32 a to the second connection portion 36. doing.

  By connecting the pair of input link members 31, the pair of first connection link members 32, the pair of second connection link members 33, and the pair of end link members 34 in this order from above, the force-increasing mechanism unit 30 is The pantograph structure in which three pantographs having a substantially rhombus shape in front view are arranged in series in the vertical direction is configured.

  As shown in FIGS. 1 and 3, the force-increasing mechanism 30 configured as described above is configured to rotatably connect the third cross connecting portion 33 a to the substantially center in the width direction Y of the bridge portion 22 of the support base 20. I support it. For this reason, as shown in FIG.1 and FIG.4, the force increase mechanism part 30 is expanded-contracted to an up-down direction from the 3rd cross connection part 33a.

  In other words, as shown in FIG. 4, the force-increasing mechanism unit 30 includes a lower pantograph structure 30 a that extends and contracts in the vertical direction with the gripping mechanism unit 40 connected to the lower end and the third cross-connecting unit 33 a as a starting point. And a pair of handles 31a, and an upper pantograph structure 30b that expands and contracts in the vertical direction starting from the third cross connection portion 33a.

  The booster mechanism 30 boosts the input load to the pair of handles 31a by the upper pantograph structure 30b and the lower pantograph structure 30a, and converts the load boosted by the lower pantograph structure 30a into a load in the vertical direction. It can be converted and transmitted to the gripping mechanism 40.

  More specifically, the force-increasing mechanism unit 30 enables the gripping mechanism unit 40 to be moved to a position close to the bridge unit 22 of the support frame 20 in a state where the support unit 20 is retracted in the vertical direction (see FIG. 1). On the other hand, in the state extended in the up-down direction, the force-increasing mechanism 30 enables the gripping mechanism 40 to be moved to a position where the lower end of the gripping member 42 is exposed below the base plate 10 (see FIG. 4).

  At this time, the pair of handles 31a are closest to each other when the force-increasing mechanism 30 is extended in the vertical direction, and move so as to rotate upward or downward with the third cross coupling portion 33a as the rotation center. At the same time, the force-increasing mechanism 30 moves so as to be farthest away in a state where it is contracted in the vertical direction.

In other words, the force-increasing mechanism 30 is configured to be a lever that rotates the pair of handles 31a with the third cross coupling portion 33a as a fulcrum.
Furthermore, as shown in FIG. 4, the booster mechanism 30 is retracted in the vertical direction with respect to the linear distance R1 from the third cross-connecting portion 33a to the handle 31a in the state where the booster mechanism 30 extends in the vertical direction The linear distance R2 from the third cross connection portion 33a to the handle 31a becomes shorter.

  That is, when the linear distance R1 in the state in which the force-increasing mechanism 30 is extended in the vertical direction is the rotation radius R1, and the linear distance R2 in the state in which the force-increasing mechanism 30 is retracted in the vertical direction is the rotational radius R2, the force-increasing mechanism 30 As the upper pantograph structure 30b expands and contracts, the rotation radius continuously changes from the rotation radius R1 to the rotation radius R2 or from the rotation radius R2 to the rotation radius R1.

Therefore, it can be said that the force-increasing mechanism unit 30 is a lever in which the rotation radius of the handle 31a that rotates with the third cross connection portion 33a as a fulcrum changes continuously.
In this embodiment, the ratio of the rotation radius R1 to the rotation radius R2 is 1: 2.

Further, as shown in FIG. 1, the gripping mechanism portion 40 is connected to the fourth cross connection portion 34a in the force-increasing mechanism portion 30 and is made of a nonmagnetic metal member such as an aluminum alloy.
More specifically, as shown in FIGS. 5 to 7, the gripping mechanism portion 40 includes a main shaft member 41 to which the fourth cross connection portion 34 a of the force-increasing mechanism portion 30 is connected, and a pair of gripping members 42 that grip the rotor 102. And a pair of opening / closing link members 43 that connect the main shaft member 41 and the gripping member 42, and a support member 44 that supports the main shaft member 41 and the pair of gripping members 42.

  As shown in FIGS. 5 and 6, the main shaft member 41 has a main body 41 a whose upper end is connected to the force-increasing mechanism 30 and a stopper 41 b disposed at the lower portion of the main body 41 a. It is integrally formed in a letter shape.

  The main spindle body 41a is a substantially quadrangular columnar body that extends in the vertical direction, and has a pair of end link members 34 that can be connected at the upper end and a pair of open / close link members 43 that are rotatably connected at the lower end. . Hereinafter, the connecting portion between the main shaft member 41 and the opening / closing link member 43 is referred to as a main shaft side connecting portion 40a.

  The stopper portion 41b extends from the lower portion of the main spindle body portion 41a toward the outside in the width direction Y, and in the fully closed state in which the lower ends of the pair of gripping members 42 indicated by the solid lines in FIG. A guide bolt 443 of a support member 44 described later is formed so as to be able to contact from below.

  Further, as shown by a two-dot chain line in FIG. 6, the stopper portion 41 b is a ball that maintains a fully open state in which the lower ends of the pair of gripping members 42 are separated in the width direction Y by the pair of opening / closing link members 43. Two plungers 45 are provided.

The ball plunger 45 is configured such that a sphere can be projected and retracted in the front-rear direction X, and is screwed into a screw hole (not shown) formed in advance in the stopper portion 41b.
The ball plunger 45 is located on the front surface of the stopper portion 41b in one side in the width direction Y and the rear surface of the stopper portion 41b in the other side in the width direction Y at a position spaced apart from the main shaft side connecting portion 40a in the width direction Y. Each has one.

As shown in FIGS. 5 and 6, the gripping member 42 is integrally formed by a substantially quadrangular prism-shaped gripping body 42 a that is long in the vertical direction and a latching claw 42 b provided at the lower end of the gripping body 42 a.
The grip main body 42 a is pivotally supported on the support member 44 with the upper end of the grip body 42 a as a rotation axis.

  In the middle of the grip body 42a in the up-down direction, one end of the open / close link member 43 is rotatably connected with the front-rear direction X as the rotation axis. More specifically, the grip main body 42a is formed so as to be connected to the open / close link member 43 at a position below the main shaft side connecting portion 40a in a fully closed state in which the lower ends are close to each other.

Hereinafter, the connecting portion between the gripping member 42 and the opening / closing link member 43 is referred to as a gripping side connecting portion 40b.

  Next, an extraction method for extracting the rotor 102 upward from the motor unit 100 using the rotor extraction device 1 having the above-described configuration will be described with reference to FIGS. 8 to 13.

  FIG. 8 is an explanatory view for explaining the configuration of the motor unit 100, FIG. 9 is an explanatory view for explaining the extraction device placing step, the first forward step, and the gripping member separation step, and FIG. 10 is a gripping member. The explanatory view explaining operation of grasping mechanism part 40 in a separation process is shown.

Further, FIG. 11 is an explanatory diagram for explaining the gripping process and the first return path process, FIG. 12 is an explanatory diagram for explaining the operation of the gripping mechanism unit 40 in the gripping process, and FIG. 13 is a second forward path process, gripping The explanatory view explaining the member separation process and the 2nd return way process is shown.
9 to 13, the slide support mechanism 50 is not shown for clarity.

Here, the motor unit 100 will be briefly described with reference to FIG.
The motor unit 100 is an electric motor of a hybrid vehicle. As shown in FIG. 8, the motor unit 100 has a substantially annular stator 101 in plan view, a rotor 102 having a rare earth magnet disposed inside the stator 101, and a shaft of the rotor 102. The housing 103 has an opening in the direction and accommodates and holds the stator 101 and the rotor 102.
The rotor 102 is a squirrel cage having a vertical axis as a rotation axis, and includes a flange portion 102a protruding outward at one end in the axial direction.

First, as a sampling device placement step, an operator places the motor unit 100 on the floor with the opening of the housing 103 facing upward as shown in FIG. Thereafter, as shown in FIG. 9A, the operator places the rotor extraction device 1 so that the lower surface of the base plate 10 is brought into contact with the upper surface of the housing 103 in the motor unit 100.
At this time, the operator aligns the position of the base plate 10 with respect to the housing 103 so that the rotor 102 can pass through the rotor insertion hole 11.

  In addition, as shown in FIG. 9A, the rotor extraction device 1 is in a state in which the force-increasing mechanism portion 30 is retracted in the vertical direction and the gripping mechanism portion 40 is close to the bridge portion 22 of the support base 20. Further, the position of the gripping mechanism unit 40 in this state is set as the initial position of the gripping mechanism unit 40.

  When an operator who has placed the rotor extraction device 1 on the motor unit 100 grips the pair of handles 31a and starts rotating the pair of handles 31a upward, the rotor extraction device 1 is shown in FIG. As shown, the first forward process of moving the gripping mechanism 40 downward is started.

  Specifically, when the pair of handles 31a starts to rotate upward with the third cross connection portion 33a as the rotation center, the upper pantograph structure 30b faces upward with the third cross connection portion 33a as a starting point. At the same time, the lower pantograph structure 30a starts to extend downward in conjunction with the extension of the upper pantograph structure 30b.

  For this reason, the force-increasing mechanism 30 is deformed from a front rhombus pantograph structure that is long in the width direction Y to a front rhombus pantograph structure that is long in the vertical direction. The gripping mechanism 40 starts to move downward due to the downward extension of the lower pantograph structure 30a.

  At this time, since the second cross connection portion 32a, the third cross connection portion 33a, and the main shaft side connection portion 40a are supported by the slide support mechanism portion 50, the gripping mechanism portion 40 has the front-rear direction X and the width direction Y. While being restricted from moving to, it moves downward along the guide shaft 51.

  Then, when the pair of gripping members 42 reach the inside of the motor unit 100 through the gap of the opening / closing lid 12 in the base plate 10, the guide roller 46 comes into contact with the rotor 102 as shown in FIG. The position of the gripping mechanism unit 40 in a state where the guide roller 46 is in contact with the rotor 102 is set as a gripping position of the gripping mechanism unit 40.

  After the gripping mechanism 40 reaches the gripping position, when the pair of handles 31a gripped by the operator is further rotated upward, the rotor extraction device 1 has a pair of gripping members 42 as shown in FIG. 9B. The gripping member separating step for separating the opening so as to open is started.

  Specifically, as shown in FIG. 10, when the guide roller 46 contacts the rotor 102, the downward movement of the pair of gripping members 42 and the support member 44 is restricted. Only the main shaft member 41 is moved further downward.

  At this time, since the main shaft member 41 presses the pair of opening / closing link members 43 downward via the main shaft side connecting portion 40a, the pair of opening / closing link members 43 rotate downward with the gripping side connecting portion 40b as the rotation center. Start.

  When the pair of opening / closing link members 43 starts to rotate, the pair of gripping members 42 starts to rotate outward in the width direction Y with the connection point with the support member 44 as the center of rotation, and the lower ends thereof are separated from each other. . At this time, the guide roller 46 in contact with the rotor 102 rotates, so that the guide roller 46 guides the rotation in the direction in which the lower ends of the pair of gripping members 42 are separated from each other.

  Thereafter, when an operator who has confirmed that the pair of gripping members 42 are separated from the flange portion 102a of the rotor 102 starts to rotate downward with the gripped pair of handles 31a, the rotor extraction device 1 is configured as shown in FIG. As shown to (a), the holding process which makes a pair of holding member 42 approach is started.

  Specifically, when the pair of handles 31a starts to rotate upward with the third cross connection portion 33a as the rotation center, the upper pantograph structure 30b faces downward with the third cross connection portion 33a as a starting point. While starting to shrink, the lower pantograph structure 30a starts to shrink upward in conjunction with the shrinkage of the upper pantograph structure 30b.

  At this time, as shown in FIG. 12, since the main shaft member 41 can move relative to the support member 44, the main shaft member 41 starts to move upward relative to the support member 44. When the main shaft member 41 starts to move, a load that pulls upward acts via the main shaft side connecting portion 40a, so that the pair of opening / closing link members 43 starts to rotate upward with the gripping side connecting portion 40b as the rotation center. .

  When the pair of opening / closing link members 43 starts to rotate, as shown in FIG. 12, the pair of gripping members 42 starts to rotate inward in the width direction Y with the connection portion with the support member 44 as the rotation center. And the lower ends thereof are close to each other.

At this time, the guide roller 46 in contact with the rotor 102 rotates, so that the guide roller 46 guides the rotation in the direction in which the lower ends of the pair of gripping members 42 are close to each other.
Thereafter, with the upward movement of the main shaft member 41, the latching claws 42 b of the pair of opening / closing link members 43 are latched on the flange portion 102 a of the rotor 102.

  Subsequently, when the operator further rotates the gripped pair of handles 31a downward, the rotor extraction device 1 starts the first return path step of moving the gripping mechanism 40 upward as shown in FIG. 11B. To do.

  Specifically, the force-increasing mechanism unit 30 increases the input load input to the handle 31a by the operator by means of a lever that continuously changes the radius of rotation of the handle 31a that rotates with the third cross connection portion 33a as a fulcrum. At the same time, the increased input load is converted into an upward tensile load by the lower pantograph structure 30a to move the gripping mechanism 40 upward.

  At this time, since the tensile load acting on the main shaft member 41 and the own weight of the rotor 102 continue to act as a load for rotating the pair of opening / closing link members 43 upward, the gripping mechanism 40 has the rotor 102 and the latching claw. While maintaining the latching state with 42b, it moves upward along the guide shaft 51.

  When the rotor 102 passes through the rotor insertion hole 11, the rotor 102 contacts the pair of opening / closing lids 12 and rotates the opening / closing lid 12 upward. Thereafter, when the rotor 102 is separated from the opening / closing lid 12, the pair of opening / closing lids 12 are rotated downward by the urging force of the hinge 13 and come into contact with the base plate 10 so as to cover the rotor insertion hole 11.

  When an operator who has confirmed that the gripping mechanism section 40 that moves upward has moved to the initial position starts rotating the gripped pair of handles 31a upward, the rotor extraction device 1 is configured as shown in FIG. As shown in FIG. 2, the gripping mechanism 40 moves downward to start the second forward path step of placing the rotor 102 on the opening / closing lid 12 of the base plate 10.

  Specifically, when the pair of handles 31a starts to rotate upward with the third cross coupling portion 33a as the rotation center, the rotor extraction device 1 is similar to the above-described first forward step, in the force-increasing mechanism portion 30. Moves the gripping mechanism portion 40 downward to bring the rotor 102 into contact with the opening / closing lid 12.

  Then, similarly to the gripping member separation step described above, the rotor extraction device 1 causes the lower end of the pair of gripping members 42 to be moved by the force-increasing mechanism unit 30 moving the main shaft member 41 downward relative to the support member 44. The gripping state of the rotor 102 is released by separating in the width direction Y.

  At this time, when the engaging hole 431a and the engaging hole 432a of the opening / closing link member 43 are engaged with the ball plunger 45 of the main shaft member 41 with the rotation of the pair of opening / closing link members 43, the holding mechanism 40 Regulates the rotation of the pair of opening / closing link members 43 and maintains the fully opened state of the pair of gripping members 42.

  When an operator who confirms that the gripping of the rotor 102 has been released starts to rotate the gripped pair of handles 31a downward, the rotor extraction device 1 has a gripping mechanism section as shown in FIG. A second return path step for moving 40 upward toward the initial position is started.

  Specifically, when the pair of handles 31a starts to rotate upward with the third cross coupling portion 33a as the center of rotation, the rotor extraction device 1 increases the force-increasing mechanism portion 30 in the same manner as the first return path step described above. Moves the gripping mechanism 40 upward.

  At this time, since the ball plunger 45 is engaged with the locking holes 431 a of the pair of opening / closing link members 43, the pair of gripping members 42 and the supporting member 44 move upward together with the main shaft member 41. .

  Then, when the operator who has confirmed that the gripping mechanism unit 40 has moved to the initial position rotates the gripped pair of handles 31a further downward, the rotor extraction device 1 contacts the end link member 34 from below. By bringing the contact member 47 into contact, the fully opened state of the pair of gripping members 42 is released.

  Specifically, when the contact member 47 contacts the end link member 34, the upward movement of the pair of gripping members 42 and the support member 44 is restricted. On the other hand, only the main shaft member 41 is moved further upward.

  At this time, since the upward tensile load acts on the pair of opening / closing link members 43 as a load for rotating the pair of opening / closing link members 43 upward through the main shaft side connecting portion 40a, the ball plunger 45 is engaged. The stop hole 431a and the locking hole 432a are detached.

  In this manner, the pair of gripping members 42 is released from the fully open state, and the pair of opening / closing link members 43 starts to rotate upward, so that the pair of gripping members 42 shifts to the fully closed state.

The rotor extraction method using the rotor extraction apparatus 1 that realizes the above operation can easily extract the rotor 102 from the housing 103.
Specifically, the rotor 102 can be extracted with a small input load by using the force-increasing mechanism 30 that increases the input load.

  For this reason, the extraction method of the rotor 102 can reduce the burden placed on the operator even if the rotor 102 is heavy, for example.

  Furthermore, since the increased input load is converted into an upward tensile load, the method of extracting the rotor 102 can reliably move the rotor 102 in the vertical direction by the tensile load.

  Thereby, even if it is the case of the rotor 102 which emits a strong magnetic force, the extraction method of the rotor 102 can extract the rotor 102 easily, without adsorb | sucking to the stator 101. FIG.

  In addition, the operator's operation for rotating the handle 31a upward and the operator's operation for rotating the handle 31a downward are received in this order, so that the extraction method of the rotor 102 continues a series of operations. Can be done.

Thereby, the extraction method of the rotor 102 can extract the rotor 102 arrange | positioned inside the housing 103, without an operator releasing a hand from the handle | steering-wheel 31a.
Furthermore, since the rotor 102 can be extracted by an input load input by an operator operating the handle 31a, the rotor 102 can be extracted without using a driving device or a power supply device that moves the gripping mechanism 40. The rotor 102 can be extracted.
Therefore, the method for extracting the rotor 102 can easily extract the rotor 102 from the housing 103.

  Further, when the pair of gripping members 42 of the gripping mechanism portion 40 are inserted into the gap between the opening / closing lid 12 of the base plate 10 in the first forward path step, and the rotor 102 passes through the rotor insertion hole 11 in the first return path step. The spring of the hinge 13 provided on the base plate 10 closes the open / close lid 12 opened by the rotor 102, whereby the rotor 102 can be extracted efficiently.

  Specifically, since the opening / closing lid 12 is disposed so that the pair of gripping members 42 can be inserted, the method of extracting the rotor 102 can facilitate the alignment of the housing 103 and the base plate 10.

Further, since the opening / closing lid 12 is closed by the spring of the hinge 13 after the rotor 102 passes through the rotor insertion hole 11, the removal method of the rotor 102 can prevent the opening / closing lid 12 from being left open. The trouble of closing the opening / closing lid 12 can be saved.
In addition, the opening / closing lid 12 can function as a mounting table on which the extracted rotor 102 is mounted.

Furthermore, the opening / closing lid 12 can function as a protective member that protects the housing 103 and the like from the dropped rotor 102 when the rotor 102 is removed from the gripping mechanism 40.
Therefore, the rotor 102 can be extracted efficiently by providing the base plate 10 with the openable / closable lid 12.

  In addition, after the first return path process, the gripping mechanism 40 is moved downward to make the rotor 102 contact the opening / closing lid 12, and the operator's operation to further rotate the handle 31a upward. The force-increasing mechanism 30 that receives the gripping member separates the pair of gripping members 42, and the force-increasing mechanism 30 that receives the operator's operation to rotate the handle 31 a downwards. And the second return path step of moving the rotor 102, the rotor 102 can be removed by placing the extracted rotor 102 on the opening / closing lid 12 without releasing the hand from the handle 31a. The grip can be released.

  Thereby, since the extraction method of the rotor 102 can continue the 1st outward path process after the 2nd return path process is completed, the rotor 102 can be easily and continuously extracted.

  Therefore, the method for extracting the rotor 102 is such that the extracted rotor 102 can be recovered safely and easily by the second forward process, the gripping member separation process, and the second return process, which are continuous from the first return process. In addition, the start of the first forward process can be facilitated.

  Further, in the second return path step, when the abutting member 47 of the gripping mechanism portion 40 abuts on the end link member 34, the force-increasing mechanism portion 30 moves the main shaft member 41 relative to the support member 44 and the main shaft member 41. However, by bringing the pair of gripping members 42 close to each other, the method for extracting the rotor 102 can reliably close the pair of gripping members 42 without releasing the hand from the handle 31a.

  Specifically, in the second return path process, when the gripping mechanism 40 releases the grip of the rotor 102, the pair of grips are engaged by the engagement of the locking holes 431 a and 432 a and the ball plunger 45. The fully open state of the member 42 is maintained.

  Therefore, by bringing the contact member 47 into contact with the end link member 34 at the upper side, the rotor 102 can be pulled out easily without releasing the hand from the handle 31a. Can be closed.

Thereby, the extraction method of the rotor 102 can start a 1st outward path process more reliably after a 2nd return path process is completed.
Accordingly, the rotor 102 can be extracted by bringing the contact member 47 of the gripping mechanism 40 into contact with the end link member 34, thereby ensuring that the pair of gripping members 42 are released without the operator releasing their hands from the handle 31a. Can be closed.

  Further, in the gripping member separation step, the force-increasing mechanism unit 30 moves the main shaft member 41 relative to the support member 44, and the main shaft member 41 rotates the pair of opening / closing link members 43 downward, so The member 42 is separated, and in the gripping process, the force-increasing mechanism unit 30 moves the main shaft member 41 relative to the support member 44 and the main shaft member 41 rotates the pair of opening / closing link members 43 upward. When the gripping member 42 of the rotor is brought close, the method for extracting the rotor 102 can grip the member to be extracted and release the gripping without releasing the hand from the handle 31a. Can be performed more efficiently.

  Further, when the pair of gripping members 42 are brought close to each other in the gripping process, an upward load is applied to the pair of opening / closing link members 43. Therefore, the method for extracting the rotor 102 facilitates the closed state of the pair of gripping members 42. Can be maintained. Thereby, for example, when the load along the vertical direction is applied to the rotor 102 using a press machine and the rotor 102 is extracted, or compared with the case where the rotor 102 is grasped and extracted by a construction machine (so-called heavy machine). This sampling method can prevent an excessive load from being applied to the rotor 102.

For this reason, the extraction method of the rotor 102 can prevent the deformation of the rotor 102, and can prevent the recovery of the rare earth magnet from being hindered by the deformation of the rotor 102 when the rare earth magnet built in the rotor 102 is recovered.
Therefore, the method for extracting the rotor 102 can easily extract the rotor 102 from the housing 103 without damaging the rotor 102.

There may be.

Moreover, although it was set as the power boosting mechanism part 30 comprised by the lower pantograph structure 30a and the upper pantograph structure 30b, it is not limited to this, While being able to increase the input load with respect to a handle | steering-wheel, it can be converted into the upward tensile load. If it exists, it is good also as a force-increasing mechanism part comprised by the lever different from the power-increasing mechanism part 40. FIG. Or it is good also as an intensifying mechanism part comprised combining the insulator and the gearwheel.
For example, instead of the pantograph-shaped booster mechanism 30, a booster mechanism such as a wing (lever lever) wine opener may be used.

  In addition, the pair of gripping members 42 is configured to be opened and closed by the main shaft member 41 connected to the force-increasing mechanism unit 30 and the pair of opening and closing link members 43.
