Description

  The present invention relates to an assembling apparatus and an assembling method for assembling a plate-like member having a hole or a shaft portion to an assembly to be assembled having a shaft portion or a hole that fits the hole or the shaft portion.

  Conventionally, in the process of assembling parts while fitting the holes formed in the plate-like first part to the shaft part protruding from the second part, the second part is set so that the shaft part faces upward Then, after the first part is held at a position where the hole is directly above the shaft part, the holding is released, the first part is dropped by its own weight, and the hole is fitted to the shaft part. (For example, Patent Document 1).

JP-A-10-271777

When the first part falls by its own weight, if it falls by tilting due to the deviation of the center of gravity, the outer wall of the shaft part and the inner wall of the hole hit at one point, and the first part is tilted and assembled with respect to the second part There is a risk of being. In particular, when the hole and the shaft portion have a D-shape or the like for positioning in the rotational direction, such inclination is likely to occur. Further, when the assembled first part is a part that rotates about the axis, such a tilt may cause a problem that impairs the function of the product.
The same problem also applies to the case where the plate-like first component with the shaft portion protruding downward is assembled to the second component with the hole opened upward by falling under its own weight.

The present invention has been made in view of the above-mentioned problems, and its purpose is to assemble a plate-like member having a hole that can be fitted into the shaft portion on an assembly to which the shaft portion protrudes upward. Another object of the present invention is to provide an assembling apparatus and an assembling method for preventing the inclination of the plate-like member.
Further, when assembling a plate-like member with a shaft portion that can be fitted into the hole protruding downward into an assembly to which the hole is opened upward, an assembling apparatus and an assembling method for preventing the plate-like member from being inclined. Is to provide.

The present invention relates to an assembling apparatus for assembling a plate-like member having a hole that can be fitted to the shaft portion and has a chamfered portion formed in the mouth, on the assembly to which the shaft portion protrudes upward. And a suction head, a guide pin, an elevating means and a pushing means.
The suction head horizontally holds and holds the plate-like member on the lower end surface, and the guide pin regulates the horizontal position of the plate-like member sucked and held on the lower end surface of the suction head. The elevating means lowers the suction head toward the assembly with the hole of the plate-like member and the shaft portion of the assembly being aligned.
The pushing means provided in a cylindrical shape around the guide pin suppresses the inclination of the plate member by bringing the end surface into contact with the upper surface of the plate member when the suction head releases the suction holding of the plate member. The plate member is guided so that the hole fits along the shaft portion. Further, after the hole is fitted to the tip of the shaft portion, the plate member is pushed into the shaft portion.

  With the above configuration, the inclination of the plate-like member is mainly suppressed by the action of the pushing means when the suction head releases the suction-holding of the plate-like member. Therefore, in particular, when the hole and the shaft portion have a D-shape or the like for positioning in the rotational direction, it is possible to reduce the occurrence of tilt failure during assembly.

The present invention is also provided as an assembling method for assembling a plate-like member having a hole that can be fitted into the shaft portion and has a chamfered portion at the mouth thereof to an assembly to which the shaft portion protrudes upward. Is done.
This assembly method includes the following four steps.
(A) a step of horizontally holding and holding the plate-like member on the lower end surface of the suction head while regulating the horizontal position of the plate-like member by a guide pin;
(B) a step in which the suction head descends toward the assembly in a state where the hole of the plate-like member and the shaft portion of the assembly are aligned;
(C) The suction holding of the plate-like member is released, and the pushing means provided in a cylindrical shape around the guide pin makes the end surface contact the upper surface of the plate-like member, thereby suppressing the inclination of the plate-like member. While guiding the plate member so that the hole fits along the shaft portion,
(D) A step in which the pushing means pushes the plate-like member into the shaft portion after the hole is fitted to the tip of the shaft portion.

  Furthermore, the assembling apparatus and the assembling method of the present invention are as follows: “A plate-like member in which a shaft part that can be fitted into the hole projects downward in an assembly to which a hole in which a chamfered part is formed is opened. The same applies to the case of “attaching”.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
The method of assembling the plate-like member and the assembly to be assembled according to the first embodiment of the present invention is to manufacture a rotary liquid pump integrated with a DC motor by fitting a hole of an impeller to a shaft portion of an armature. While applied to the process of assembling the impeller and armature.
The configuration of the suction head, which is the main part of the assembling apparatus used in this assembling method, will be described with reference to FIGS.

As shown in FIG. 1, the suction head 5 of the assembling device 4 is suspended from a device frame (not shown) by a suspension shaft 93. The suction head 5 can be moved up and down by the lifting and lowering means 91, and can be rotated about the suspension shaft 93 by the rotating means 92. In the following description, the upper direction in FIG. 1 will be described as “up” and the lower direction in FIG. 1 as “down”.
The suction head 5 includes a cover 51, a main body 52, a lower body 53, and the like. The suction head 5 uses negative pressure to suck and hold the impeller 20 on the lower end surface 534 of the lower body 53, and also functions so that the work is properly assembled by the built-in guide pin 6 and push sleeve 7. To do.

In the main body 52, a spring accommodating hole 521 is formed on the upper side through the center, and a sliding hole 522 is formed on the lower side. A plunger 65 is slidably accommodated in the sliding hole 522. When the rotation preventing pin 66 is fitted into the long hole 651 of the plunger 65, the rotation of the plunger 65 and the upper and lower limit positions are regulated. The spring accommodating hole 521 accommodates a spring 67 held between the lower wall of the cover 51 and the upper wall of the plunger 65. The spring 67 urges the plunger 65 downward.
A guide pin 6 is coaxially connected to the lower portion of the plunger 65. The guide pin 6 has a D-shaped cross-sectional shape in which a part of the outer wall is cut by a flat surface 62 on the distal end 63 side of the base shaft portion 61.

  The lower body 53 has a relatively large-diameter flange hole 531 formed on the upper side through the center, and a relatively small-diameter sleeve hole 532 formed on the lower side. The pushing sleeve 7 as “pushing means” has a flange portion 71 at the upper end accommodated in the flange hole 531, and a sliding portion 72 below the flange portion 71 is slidably accommodated in the sleeve hole 532. . The inner wall of the pushing sleeve 7 guides the sliding of the base shaft portion 61 of the guide pin 6. Further, the end surface 73 of the pushing sleeve 7 comes into contact with the upper surface of the impeller 20 held by suction at the lower end surface 534.

Two air paths are formed in the suction head 5.
The first air path is a path that supplies negative pressure to the plurality of suction paths 54 that open to the lower end surface 534. The air path includes a first air passage 523 formed in the main body 52, an annular air passage 533 formed in the lower body 53, and a plurality of suction passages 54. A coupler 581 is attached to the pipe screw 525 communicating with the first air passage 523, and an air hose 591 is connected to the coupler 581. With this configuration, a negative pressure is supplied to the suction head 5 from a negative pressure supply source such as a vacuum pump (not shown) via the air hose 591.

As shown in FIG. 2, in the present embodiment, the three suction paths 54 are evenly arranged in the circumferential direction between the three bolts 55 that fasten the lower body 53 and the main body 52. Thereby, the impeller 20 can be sucked in a balanced manner at three points, and can be appropriately sucked and held on the lower end surface 534.
Returning to FIG. 1, an O-ring 56 is provided between the main body 52 and the lower body 53 to prevent a negative pressure leak from the gap. A seal ring 57 is provided inside the annular air passage 533 to ensure airtightness with the flange hole 531.

  The second air path is a path for supplying knockout pressure to the upper space of the flange portion 71 of the push sleeve 7. The air path includes a second air passage 524 formed in the main body 52 and a flange hole 531 formed in the lower body 53. A coupler 582 is attached to the pipe screw 526 communicating with the second air passage 524, and an air hose 592 is connected to the coupler 582. With this configuration, a knockout pressure is supplied to the suction head 5 from a pressure supply source such as a compressor or a regulator (not shown) via the air hose 592.

Next, the structure of the impeller 20 and the armature 30 that are works of the method of assembling the plate-like member and the assembly according to the first embodiment will be described with reference to FIGS. 3 and 4.
As shown in FIG. 3, the impeller 20 as the “plate member” in the first embodiment is a “perforated plate member” in which holes 23 are formed along the central axis O of the disk. In this embodiment, since the impeller 20 is formed of resin, it is relatively light and has lubricity.
The impeller 20 rotates to pump liquid by a plurality of blades 24 formed in the circumferential direction. However, since the blade 24 does not have a technical meaning in explaining the assembling method of the present embodiment, the blade is not shown in the drawings of the impeller 20 after FIG.

  The hole 23 is formed in a D shape in which a part of a circle is connected by a string. Further, the hole 23 has a chamfered portion 232 formed at the mouth on the lower surface 22 side of the straight portion 231 with reference to the posture at the time of assembly shown in FIG. On the other hand, on the upper surface 21 of the impeller 20, a portion indicated by a two-dot chain line around the hole 23 serves as a force receiving surface 211 pressed by a pressing sleeve 7 described later.

As shown in FIG. 4, the armature 30 as the “assembly” in the first embodiment includes a columnar core 34 around which a winding is wound, and an upward direction along the central axis Q of the core 34. It comprises a protruding shaft portion 31 and constitutes a part of the armature subassembly 10.
The armature subassembly 10 is an intermediate product in the manufacturing process of the rotary liquid pump, and is set in the assembling apparatus 4 in the orientation shown in FIG. The armature 30 is accommodated in the cylindrical housing 15. An impeller case 11 holding a bearing 12 that rotatably supports the shaft portion 31 of the armature 30 is incorporated in an upper end portion of the housing 15. A holder 13 that supports the lower portion of the armature 30 is incorporated at the lower end of the housing 15. A permanent magnet 14 is provided on the inner wall of the housing 15 so as to face the core 34 in the radial direction.

  In the shaft portion 31 of the armature 30, a part of the outer wall on the tip 33 side is cut by a flat surface 32 corresponding to the D shape of the hole 23 of the impeller 20. Thus, the impeller 20 and the armature 30 are positioned in the rotational direction by fitting the hole 23 of the impeller 20 into the shaft portion 31 of the armature 30. Therefore, the impeller 20 rotates integrally with the armature 30.

Next, an assembling method of the impeller 20 and the armature 30 using the assembling apparatus 4 according to the present embodiment will be described with reference to FIGS. This assembling method includes four stages: an “adsorption holding stage”, an “alignment stage”, a “self-weight fitting stage”, and a “push-in stage”.
As shown in the lower side of FIG. 5, in the initial state, the armature 30 as the assembly is set on the receiving jig 8 with the shaft portion 31 facing upward.

(Adsorption holding stage)
As shown in the upper side of FIG. 5, the impeller 20 as a plate-like member is horizontally held by suction on the lower end surface 534 of the suction head 5 with the guide pin 6 inserted into the hole 23 and the horizontal position regulated. Is done. At this time, the suction head 5 is supplied with the negative pressure Vc to the first air passage 523, the annular air passage 533 and the suction passage 54 via the air hose 591 and the coupler 581, and sucks the upper surface 21 of the impeller 20.
Thus, the impeller 20 sucked and held on the lower end surface 534 of the suction head 5 moves toward the armature 30 set on the receiving jig 8. This movement includes at least vertical movement by the lifting means 91. In addition, it is possible to construct an automatic production line that is continuous from the previous step by accompanying horizontal movement by a conveying means (not shown).

(Alignment stage)
As shown in FIG. 6, with the suction head 5 sucking and holding the impeller 20, the elevating means 91 sucks up to a height at which the tip 63 of the guide pin 6 contacts the tip 33 of the shaft portion 31 of the armature 30. The head 5 is lowered. At this time, the hole 23 of the impeller 20 and the shaft portion 31 of the armature 30 are aligned by controlling the center of the suction head 5 to coincide with the center of the receiving jig 8. The guide pin 6 is always pressed against the tip 33 of the shaft portion 31 by the urging force Fsp of the spring 67.

  Furthermore, in this embodiment, the direction of the D-shaped hole 23 and the shaft portion 31, that is, the rotation at this stage so that the positions of the flat surface 62 of the guide pin 6 and the flat surface 32 of the shaft portion 31 substantially coincide with each other. Directional positioning is performed. Here, “substantially” means that the positioning is not exactly as much as the play of the positioning mechanism. By performing approximate positioning at this stage, it becomes easy for the impeller 20 to slightly rotate by its own weight and "follow-fit" at the next self-weight fitting stage.

(Self-weight mating stage)
Subsequently, as shown in FIG. 7, the supply of the negative pressure Vc to the suction head 5 is stopped, and the suction holding of the impeller 20 is released. At this time, the pushing sleeve 7 provided in a cylindrical shape around the guide pin 6 brings the end surface 73 into contact with the upper surface 21 of the impeller 20. Thereby, the pushing sleeve 7 maintains the attitude | position of the impeller 20 at a horizontal level, and suppresses inclination. Further, the pushing sleeve 7 guides the mouth of the hole 23 so as to fit the tip of the shaft portion 31 while the impeller 20 rotates by its own weight as indicated by an arrow C. Detailed behavior at this time will be described later.

  Depending on the size and material of the impeller 20, the shape of the hole 23 and the shaft portion 31, it may be difficult to fit the shaft portion 31 following the rotation due to its own weight. In such a case, the impeller 20 may be forcibly rotated by rotating the suspension shaft 93 by the rotating means 92.

(Indentation stage)
Thereafter, as shown in FIG. 8, the knockout pressure Pk whose flow rate and pressure are controlled is supplied to the second air passage 524 via the air hose 592 and the coupler 582 of the suction head 5. The knockout pressure Pk acts on the upper surface of the flange portion 71 of the push sleeve 7 and pushes down the push sleeve 7. Thereby, the lower end surface 73 of the pushing sleeve 7 pushes the upper surface 21 of the impeller 20, thereby pushing the impeller 20 to a predetermined height of the shaft portion 31 of the armature 30.
Thus, the assembling method using the assembling apparatus 4 according to the present embodiment is completed.

The assembling method of this embodiment is particularly characterized in the behavior of the pushing sleeve 7 in the self-weight fitting stage and the pushing stage. This feature will be described in comparison with a comparative example.
It is explanatory drawing of the assembly method of the comparative example shown in FIG. 10, The same code | symbol is attached | subjected to the structure substantially the same as this embodiment. The suction head 5x of the assembly device of the comparative example is identical to the suction head 5 of this embodiment in that the suction path 54 is formed in the lower body 53, and is different in that the pushing sleeve 7 is not provided.

  In the assembly method of the comparative example, when the suction holding of the impeller 20 by the suction head 5x is released, the impeller 20 falls by its own weight without being guided by other members. Then, for example, the impeller 20 hits the shaft portion 31 at one point illustrated by X on the side opposite to the flat surface 32 and rotates as indicated by a broken line Wi with this point as a fulcrum, and may be assembled in an inclined posture. .

  On the other hand, as shown in FIG. 9, in the assembling method of this embodiment, after the suction holding of the impeller 20 by the suction head 5 is released, the pushing sleeve 7 abuts the end surface 73 against the upper surface 21 of the impeller 20. By doing so, the posture of the impeller 20 is kept horizontal. The lightweight and lubricious resin impeller 20 rotates within its chamfered portion 232 by its own weight as indicated by an arrow C in an attempt to align the D-shape along the tip of the shaft portion 31. To do.

At this time, the friction at the contact surface between the end surface 73 of the pushing sleeve 7 and the impeller 20 becomes rotational resistance, so that the diameter of the end surface 73 is set to an appropriate size so as not to be too large relative to the diameter of the impeller 20. It is preferable to set. In addition, the followability can be improved by forming the pushing sleeve 7 with a material having good slipperiness.
By thus copying and fitting, the impeller 20 is inserted straight into the shaft portion 31 as indicated by the broken line Wp. Therefore, a stable pumping function can be exhibited as a component that rotates integrally with the armature 30 in the rotary liquid pump. In addition, it is possible to reduce the performance variation among the mass-produced rotary liquid pumps.

(Second Embodiment)
Next, a method for assembling the plate-like member and the assembly to be assembled according to the second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, another work is assembled using the same assembling apparatus 4 as in the first embodiment. In the description of the second embodiment, substantially the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 11, the plate-like member 25 of the second embodiment is a “shafted plate-like member” in which the shaft portion 28 protrudes along the central axis O. As shown in FIG. 11 (b), when the direction in which the shaft portion 28 protrudes with respect to the posture at the time of assembly is taken downward, the shaft portion 28 protrudes downward from the lower surface 27. On the other hand, a bottomed guide hole 29 is formed on the upper surface 26 of the plate-like member 25. The distal end portion of the shaft portion 28 and the guide hole 29 have a D-shaped radial cross section, and are positioned in the rotational direction with the mating member.

As shown in FIG. 12, the assembly 16 of the second embodiment is a virtual subassembly in which an end cover 17 is incorporated at the upper end of a cylindrical housing 19. The end cover 17 is formed with a hole 18 having a D-shaped cross section along the central axis Q. The hole 18 has a chamfered portion 182 formed at the mouth of the straight portion 181.
The assembled body 16 is set so that the hole 18 opens upward when assembled, and the shaft portion 28 of the plate-like member 25 is fitted into the hole 18. Thus, in 2nd Embodiment, the relationship between the hole and shaft of a plate-shaped member and a to-be-assembled body is reverse with respect to 1st Embodiment.

As in the first embodiment, there are four methods for assembling the plate-like member 25 and the assembly to be assembled 16, ie, “adsorption holding stage”, “alignment stage”, “self-weight fitting stage”, and “push-in stage”. It consists of stages.
As shown in FIG. 13, in the suction holding stage, the guide pin 6 is inserted into the guide hole 29 of the plate-like member 25 to restrict the horizontal position of the plate-like member 25, and the lower end surface 534 of the suction head 5 is placed. The upper surface 26 of the plate-like member 25 is sucked and held.
In the alignment step, the suction head 5 is lowered toward the assembly 16 with the shaft portion 28 of the plate-like member 25 and the hole 18 of the assembly 16 being aligned. In the present embodiment, the suction head 5 is lowered to such a height that the tip of the shaft portion 28 faces the chamfered portion 182 of the hole 18.

In the self-weight fitting stage, the suction holding of the plate-like member 25 by the suction head 5 is released, and the pushing sleeve 7 brings the end surface 73 into contact with the upper surface 21 of the plate-like member 25, thereby tilting the plate-like member 25. Suppress. Further, the pushing sleeve 7 guides the tip end portion of the shaft portion 28 to fit along the chamfered portion 182 of the hole 18 while the plate-like member 25 rotates by its own weight.
In the pushing step, the lower end surface 73 of the pushing sleeve 7 pushes the upper surface 26 of the plate-like member 25, thereby pushing the shaft portion 28 of the plate-like member 25 to a predetermined depth of the hole 18 of the assembly 16.
In the assembling method of the second embodiment, as in the first embodiment, it is possible to prevent the inclination at the time of assembling the plate-like member 25 and the assembly 16.
