Description

The present invention relates to a jig for transporting a machine tool part that can be attached to the machine tool part in order to transport the machine tool part.

The parts that make up a machine tool may change over time after being used for a certain period of time, or may need to be replaced due to a failure or the like. Parts that need to be replaced in machine tools range from small, light parts to relatively large parts that weigh more than 100 kg. When handling such machine tool parts, for example, for heavy parts, all the work is carried by a crane or the like. However, when working in a narrow space where a crane cannot enter, it is necessary to transport machine tool parts using a dolly or the like. At that time, transportation using a general trolley becomes unstable depending on the size and length of the machine tool parts, and there is a risk of damaging the precision-machined machine tool parts. In addition, it may be difficult to put a dolly in a narrow space.

Next, Patent Document 1 below discloses a transport jig for lifting and moving a transported object such as a large storage shelf or a cabinet. The transport jig is provided with a connecting base whose height can be adjusted by operating a jack on a support base having wheels, and an attachment for mounting a transported object is attached to the connecting base. There is. The attachment is composed of a pair of members, a support frame body is fixed to the connecting base, and a detachable mounting body is attached to the transported object to be transported. Then, the support frame body is raised by the operation of the jack, and the conveyed object is lifted by connecting with the mounting body, and the support base enables the movement.

JP-A-2010-247726

Since the conventional example of Patent Document 1 is a transport jig for a large storage shelf or the like, it is not suitable for transporting precision-machined machine tool parts. Since the transport jig has a structure in which parts are supported by an attachment to a support base having a jack, the structure is complicated, the number of parts is large, and the jig itself tends to be large. In particular, as the weight of the machine tool parts increases, the transport jig also increases accordingly, making it difficult to use in a narrow work space when replacing the machine tool parts. In addition, the work of attaching attachments to machine tool parts, connecting to support bases, and lifting with jacks is also not suitable for tight work spaces. Moreover, as described above, the transportation method of lifting the machine tool from the state where it is once placed on the floor is not appropriate because it may damage the precision-machined machine tool parts.

Therefore, an object of the present invention is to provide a jig for transporting machine tool parts in order to solve such a problem.

The jig for transporting a machine tool part according to the present invention includes a part holding member made of a plate material formed according to the shape of the machine tool part , a handle member which is a member different from the part holding member, and the part holding. The part protection member in contact with the machine tool part fixed inside the member, the wheel member fixed to the lower surface of the part holding member, and the machine tool part are integrated with the part holding member and the handle member . It has a mounting member.

According to the above configuration, the part holding member is applied to the machine tool part via the inner part protecting member, and the part holding member is integrated with the machine tool part by the mounting member, so that the machine tool part is made into a part. It can be moved by a wheel member fixed to the lower surface portion of the holding member.

It is a perspective view which showed the state which the transportation jig was attached to the Z-axis slide suspended by a crane device. It is a perspective view which showed the transportation jig which carries a spindle motor. It is a perspective view which showed the transportation jig which carries a table.

Next, an embodiment of a jig for transporting machine tool parts according to the present invention will be described below with reference to the drawings. The transport jig of this embodiment is suitable for, for example, a machine tool constituting the processing machine line shown in FIG. FIG. 1 is a front view of a machine line, and particularly shows a situation at the time of parts replacement, which will be described later. The processing machine line 1 described here is a modularized working machine such as a machine tool. Two of the processing modules 5 are mounted on the base 2, and each working machine such as a machine tool is covered with a machine body cover. In particular, in the processing machine line 1, a work space 3 is provided between the bases 2 on which the two processing modules 5 are mounted so that an operator can enter.

FIG. 2 is a side view showing the internal structure of a machine tool, which is one of the machining modules 5 constituting the machining machine line 1. The machine tool 10 is mounted on a movable bed 11 provided with wheels. A spindle device 12 that gives rotation to the work is fixed on the movable bed 11 of the machine tool 10, and a column 13 on which a drive device or the like is mounted is erected next to the spindle device 12. The rotation axis (main axis) of the spindle device 12 is in the front-rear direction of the machine body and is horizontal. In the present embodiment, the horizontal axis parallel to the main axis is the Z axis, the vertical direction of the machine body orthogonal to the Z axis is the X axis, and the width direction of the machine body is the Y axis.

The spindle device 12 is configured such that a spindle chuck 14 for gripping a workpiece and a driven pulley are integrally formed with respect to a spindle supported rotatably, and the rotation of the spindle motor 15 is transmitted via a timing belt. There is. A turret device 16 having a plurality of tools 19 is mounted on the column 13, and a Z-axis drive device 17 and an X-axis drive device 18 for moving the tool 19 in the Z-axis direction and the X-axis direction are assembled to the work. There is. The machine tool 10 is a biaxial lathe that moves the tool 19 in the Z-axis direction and the X-axis direction.

When replacing parts of such a machine tool 10, for example, the Z-axis slide 21 constituting the Z-axis drive device 17 is an important part that affects the machining accuracy of the work, so it is necessary to pay particular attention to scratches and the like. The Z-axis slide 21 slides the Z-axis guide 22 fixed to the X-axis drive device 18 side to which the turret device 16 is integrally assembled. That is, the tool 19 is moved in the Z-axis direction, and the sliding surface thereof is processed with micron-level flatness and parallelism. Therefore, it is necessary to take the utmost care to avoid collisions and damage to the new Z-axis slide 21 when replacing parts.

Subsequently, a transportation jig for transporting the Z-axis slide 21 will be described. The parts of the machine tool 10 are disassembled, assembled, and transported by the worker, but the work space 3 of the machine tool line 1 is provided only wide enough for the worker to put his / her body. Therefore, it is not possible to enter a general dolly, and even if it is possible to enter, it is difficult to transport the machine tool parts without damaging them. In particular, it is very difficult for one worker to carry the Z-axis slide 21, which is a 100 kg long part, while maintaining a stable state. The transport jig of the present embodiment is excellent for transporting in such a narrow work space 3 and for one worker to transport heavy machine tool parts.

3 and 4 are views showing a state in which the Z-axis slide 21 is transported by the transport jig of the present embodiment, and FIG. 3 is a longitudinal side view of the Z-axis slide 21 during transportation. , FIG. 4 is a front view of the Z-axis slide 21 during transportation in the longitudinal direction. FIG. 5 is a perspective view showing the transport jig of the present embodiment. The transport jig 7 is integrally attached to the machine tool component to be transported, that is, the Z-axis slide 21, and makes the Z-axis slide 21 itself movable. Therefore, the transport jig 7 having the same configuration is symmetrically attached to both ends in the longitudinal direction on the Z-axis slide 21, which is a long component.

The transport jig 7 has a component holding member 31 formed according to the shape of the Z-axis slide 21, a caster 32 is fixed to a lower surface portion thereof, and a handle member 33 is provided so as to extend upward. There is. The component holding member 31 supports the lower surface 213 and the back surface 215 of the Z-axis slide 21 from the opposite side of the polished sliding surface 211. The component holding member 31 is formed by bending a strip-shaped iron plate having a constant width into an L shape, and a curved portion 311 is formed at a corner portion in order to avoid stress concentration. Two casters 32 are attached to the lower surface of the component holding member 31 at positions where a balance can be obtained during transportation.

The component holding member 31 has a protective block 34 fixed to the inside so as not to be damaged by directly hitting the Z-axis slide 21. The protective block 34 is a block made of a resin material and has a rectangular cuboid shape, and is fixed to each of the bottom surface portion 313 and the side surface portion 315 of the component holding member 31. A handle member 33 is detachably attached to the component holding member 31 on the outside of the side surface portion 315. That is, the component holding member 31 and the handle member 33 are separate members, and are integrated when fixed to the Z-axis slide 21 as shown in the figure.

The handle member 33 is formed by bending an iron pipe into an L shape, and forming a handle portion 331 that remains circular and a fixing portion 333 that is flatly deformed by crushing. The fixing portion 333 is formed with two mounting holes 335 at the top and bottom. On the other hand, the side surface portion 315 of the component holding member 31 is also formed with two mounting holes 317 at the top and bottom so as to overlap the two mounting holes 335. The component holding member 31 is also formed with two screw holes 318 next to the mounting holes 317. The screw hole 318 is for tightening a bolt through the mounting hole 335 of the handle member 33 in order to integrally store the component holding member 31 and the handle member 33, which are separate members.

The transport jig 7 has an integral structure in which the component holding member 31 and the handle member 33, which are two separated components, are as shown in the figure when they are attached to the Z-axis slide 21. For that purpose, the upper and lower mounting holes 317 and 335 are overlapped so as to coincide with each other, and the mounting bolts 35 penetrating the mounting holes 317 and 335 are fastened to the Z-axis slide 21 to be integrally assembled. The component holding member 31 and the handle member 33 may be configured as one component, but in order to eliminate welding for connecting the component holding member 31 and the handle member 33, the component holding member 31 and the handle member 33 may be configured as two components in the present embodiment. .. Then, in order to integrally fix these two parts to the machine tool parts, the screw holes formed in the mounting bolt 35 and the Z-axis slide 21 are used.

Since the Z-axis slide 21 is assembled as a part of the machine tool 10 as shown in FIG. 2, a screw hole 217 is formed in advance on the back surface 215 side. The transport jig 7 of the present embodiment is attached by using a structure previously formed in a machine tool component such as a screw hole 217. In addition to screw holes, some machine tool parts have through holes, so-called stupid holes. In the case of such machine tool parts, the transport jig may be integrally attached by tightening the mounting bolt and the nut through the through hole. In this respect, the transport jig 7 of the present embodiment is configured to integrate the component holding member 31 and the handle member 33 with the Z-axis slide 21 by tightening the mounting bolt 35 to the screw hole 217. There is.

The transport jig 7 is directly attached to the Z-axis slide 21 and makes the machine tool part itself a moving body. Further, in order to enable transportation in a narrow space such as the work space 3, the transportation jig 7 is configured so as not to greatly protrude from the outer shape of the machine tool parts. However, when the machine tool part itself is a moving body, the machine tool part may directly collide with something during transportation. Therefore, the transport jig 7 is provided with a bumper member 36 for protecting the machine tool parts while preventing the protrusion amount from becoming large.

The bumper member 36 of the transport jig 7 is configured to protect the longitudinal end of the Z-axis slide 21, which is the tip in the traveling direction during transportation. The bumper member 36 is formed of a thin iron plate so that it can be deformed and absorb an impact at the time of a collision. The bumper member 36 is fixed to the lower surface of the component holding member 31, and a protective portion 361 that protrudes only to one side in the width direction of the bottom surface portion 313 and is further curved upward is formed. Therefore, when the transport jig 7 is attached, the protective portion 361 protrudes from the longitudinal end portion of the Z-axis slide 21.

Subsequently, the transportation using the transportation jig 7 performed in association with the replacement work of the Z-axis slide 21 will be described. When the Z-axis slide 21 is removed from the machine tool 10, the simple crane device 41 is fixed to the column 13, and the Z-axis slide 21 is suspended as shown in FIG. FIG. 6 is a perspective view showing a Z-axis slide 21 suspended by a simple crane device 41 and to which a transport jig 7 is attached. A hanging jig 42 is used to suspend the Z-axis slide 21. In the hanging jig 42, a pair of fixing plates 421 are connected by a rod 422. The fixing plate 421 utilizes a screw hole 219 (see FIG. 4) previously formed in the longitudinal end face of the Z-axis slide 21 and is fastened to the screw hole 219 by a bolt.

The Z-axis slide 21 to which the hanging jig 42 is attached is connected to the hook 411 via the plate 43, and is suspended by the simple crane device 41, to which the transport jig 7 is attached. The operator holds the transport jig 7 in the mounting ready state through the mounting bolts 35 in the mounting holes 317 and 335 of the component holding member 31 and the handle member 33, and mounts the Z-axis slide 21 suspended. .. For example, two transport jigs 7 performed by one operator at both ends of the Z-axis slide 21 are sequentially attached one by one.

The operator lifts the transport jig 7 and arranges the transport jig 7 so as to put the protective block 34 on the mounting position of the Z-axis slide 21. Specifically, a state in which the component holding member 31 and the handle member 33 are connected while supporting the component holding member 31 from below with one hand and pressing the mounting bolt 35 through the mounting holes 317 and 335 with the other hand. To maintain. Then, while the transport jig 7 is supported, the mounting bolt 35 is tightened to the screw hole 217 of the Z-axis slide 21 to fix the transport jig 7 to the Z-axis slide 21. In this way, a pair of transport jigs 7 are integrally attached to the Z-axis slide 21 at both ends in the longitudinal direction as shown in FIG.

The transport jig 7 of the present embodiment weighs about 2 to 3 kg. Therefore, even one operator can attach the Z-axis slide 21 suspended at an appropriate height by the simple crane device 41. Moreover, the mounting structure is as simple as tightening the mounting bolt 35 into the screw hole 217 of the Z-axis slide 21, and the mounting can be easily performed even in a narrow work space 3. Further, since the transport jig 7 is made so as not to protrude significantly from the machine tool parts, the Z-axis slide 21 to which the transport jig 7 is attached is lowered onto the floor and separated from the simple crane device 41. Later transportation can be smoothly moved from the narrow work space 3.

Further, during transportation, vibration is transmitted from the caster 32 to the Z-axis slide 21, but the transportation jig 7 does not cause scratches on the Z-axis slide 21 to which the protective block 34 made of resin is applied. Further, even if a collision occurs during transportation, the bumper member 36 protects the Z-axis slide 21. Although the handle member 33 is assembled to the transport jig 7 of the present embodiment, the presence of the handle member 33 makes it convenient for the operator to handle during transportation. On the other hand, the Z-axis slide 21 can be transported even when the handle member 33 is removed, and in particular, in the present embodiment, the component holding member 31 and the handle member 33 are separate members. Therefore, by not assembling the handle member 33, the work of attaching the transport jig can be further simplified, and the object to be transported during transportation can be made more compact.

By the way, there are various machine tool parts other than the Z-axis slide 21, but the transport jig of the present embodiment can be dealt with by changing the design according to the object to be transported. For example, FIG. 7 is a perspective view showing a transport jig for transporting the spindle motor 15 of the machine tool 10. Since the spindle motor 15 is symmetrical when viewed in the axial direction of the motor shaft 151, the pair of transport jigs 8 are configured to support along the longitudinal direction in consideration of the balance during transportation. ing. Specifically, in the transport jig 8, a component holding member 51 is formed according to the dimensions of the spindle motor 15, two casters 52 are fixed to the lower surface portion thereof, and the side surface portion extends upward. The handle member 53 can be attached.

The spindle motor 15 is formed with screw holes for assembly at four corners at the protruding motor shaft 151 side end. The transport jig 8 supports the spindle motor 15 from the motor shaft 151 side to the lower side, and a protective block 54 made of a resin material is fixed to the inside. A bumper member 56 is provided to protect the spindle motor 15 from both sides in the width direction. In such mounting of the transport jig 8, the operator holds the transport jig 8 in the mounting ready state by passing the mounting bolt 55 through the mounting holes formed in the component holding member 51 and the handle member 53, and is in a suspended state. It is completed by tightening the mounting bolt 55 after aligning with the spindle motor 15.

Further, the transport jig of the present embodiment can be used for machine tool parts of a machine tool different from the machine tool 10. FIG. 8 is a perspective view showing a transport jig for transporting a table 101 incorporated in another machine tool. The table 101 is also formed with screw holes for assembly. The transport jig 9 is attached by using the screw holes, and the component holding member 61 is formed according to the dimensions of the table 101, and the bumper member 66 and the two casters 62 are fixed to the lower surface portion thereof. A protective block 64 made of a resin material is fixed to the inside. Then, the transport jig 9 is integrally attached to the table 101 by passing the mounting bolts 65 through the mounting holes formed in the component holding member 61 and the handle member 63 and tightening them into the screw holes.

Although one embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, a pair of transport jigs are attached to the machine tool parts, but depending on the machine tool parts, one transport jig to which four casters are attached may be used.
Further, the shapes of the component holding member, the handle member, and the like may be different from those of the above-described embodiment.
