BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traverse device such as a lead wire peeling machine having a reciprocating table, and more particularly to a mechanism for changing a traverse position.

[0002]

2. Description of the Related Art Conventionally, a peeling machine used for peeling the skin of a lead wire is configured to perform peeling by a cutter attached and fixed to two movable bodies (tables) which can reciprocate.

A reciprocating operation of each table uses a cam device using a cylindrical cam. As a configuration of this cam device, a cylindrical cam having a cam groove formed thereon is fixed to a shaft rotated by motor power, and the cylindrical cam is rotated integrally with the shaft. A roller connected to the table is engaged with the cam groove.

Therefore, when the motor is driven, the cylindrical cam is rotated together with the shaft, and the roller engaged with the cam groove follows the cam groove with the rotation. As a result, the table is reciprocated in the axial direction of the shaft.

[0005]

However, the above-mentioned peeling machine has the following problems. Since the cylindrical cam is fixed to the shaft, the traverse position of the table is always the same. That is, the interval between the two tables cannot be changed.

As a result, for example, when the distance between the two cutters is changed in accordance with the change in the diameter of the lead wire, the distance between the tables cannot be changed as described above. The distance between the cutters is changed by adjusting the mounting position. In this case, since the adjustment work must be performed by disassembling the apparatus, there is a problem that the time required for the work is lengthened and the work efficiency is deteriorated.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a traverse device which can easily change a traverse position of a moving body.

[0008]

[0009]

According to the present invention, when the shaft is rotated, the three-dimensional cam is integrally rotated with the rotation. At this time, the moving body reciprocates in the axial direction of the shaft following the cam groove formed in the three-dimensional cam. When changing the traverse position of the moving body, the three-dimensional cam may be moved in the axial direction of the shaft by the positioning means and fixed at that position. In particular, in the invention according to claim 1, the second shaft

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A first embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, a shaft 2 is rotatably supported by a frame 1 having an open top and bottom, and the shaft 2 is rotated by a motor (not shown). A spline 3 is formed on a part of the outer periphery of the shaft 2 in the frame 1. A first cylindrical cam 4 as a three-dimensional cam is spline-connected to the spline 3. Therefore, the first cylindrical cam 4 rotates integrally with the shaft 2 and the shaft 2
It can be relatively moved in the axial direction.

The outer periphery of the shaft 2 where the spline 3 is not formed is formed to have a smaller diameter than the outer periphery of the shaft 2 where the spline 3 is formed. A second cam as a three-dimensional cam is provided around the outer periphery of the shaft 2.
The cylindrical cam 5 is keyed. Therefore, the second cylindrical cam 5 also rotates integrally with the shaft 2 similarly to the first cylindrical cam 4.

The end face of the second cylindrical cam 5 and the frame 1
The collar 6 is inserted into the shaft 2 between the inner surface of the shaft 2 and the inner surface of the shaft 2. That is, the second cylindrical cam 5 is held between the end face of the spline 3 of the shaft 2 and the collar 6 while being inserted through the shaft 2. Therefore, the second cylindrical cam 5 cannot move relative to the shaft 2 in the axial direction. In the present embodiment, the shaft 2
The portion where the spline 3 is formed is the first shaft
And the part where the spline 3 is not formed is the second part.
It has a shaft.

As shown in FIGS. 1 and 2, a plate 8 having an opening 7 in the center is formed at the lower portion of the frame 1.
Is attached and fixed. A pair of rails 9 extending in the axial direction of the shaft 2 is fixedly mounted on the upper surface of the plate 8 through the opening 7. A cam position adjustment table 11 is supported on each rail 9 by a guide 10 on its lower surface. A pair of regulating rollers 12 abutting on the end surface of the first cylindrical cam 4 are connected and fixed to the cam position adjusting table 11, respectively.

The cam position adjusting table 11 is integrally formed with a pressed portion 13 projecting downward from the opening 7 of the plate 8. Brackets 14 and 15 are respectively connected and fixed to the plate 8 so as to face the pressed portion 13. Screw holes 14a and 15a are respectively formed in the brackets 14 and 15, and bolts 16 and 1 are formed in the screw holes 14a and 15a.

A cylindrical rubber pad 20 is inserted into the tip of each of the bolts 16 and 17. These rubber pads 20 sandwich the pressed portion 13. The nuts 18a, 18b, 19a, 19b are for preventing loosening.

That is, by loosening the right bolt 16 and tightening the left bolt 17, a force is applied to the pressed portion 13 from the right in FIG. Accordingly, the cam position adjusting table 11 moves to the right side in FIG. On the other hand, by loosening the left bolt 17 and tightening the right bolt 16, the pressed portion 1
3, a leftward force in FIG. Therefore, the cam position adjusting table 11 moves to the left along the rail 9. That is, the first cylindrical cam 4 follows the movement of the cam position adjusting table 11 and moves relative to the shaft 2 in the axial direction thereof. Positioning means is constituted by the cam position adjusting table 11, the regulating roller 12, the bolts 16 and 17, and the like. Ma
In addition, the position adjustment unit is constituted by the bolts 16, 17 and the like.

FIG. 3 is an exploded view of the first and second cylindrical cams 4 and 5. A pair of endless cam grooves 4a and 5a are formed on the outer peripheral surfaces of the two cylindrical cams 4 and 5, respectively. I have.
In addition, a cam groove 4a formed in the first cylindrical cam 4;
The cam groove 5a formed in the second cylindrical cam 5 is formed symmetrically.

As shown in FIGS. 1 and 2, a pair of rails 24 are supported on both side surfaces of the frame 1. On the upper surface of the frame 1, a first table 22 and a second table 23 as moving bodies are arranged.
Guide members 25 that engage with the rails 24 are slidably engaged with both sides of the rails 2 and 23. Accordingly, each of the tables 22 and 23 moves relative to the frame 1 in the axial direction of the shaft 2.

A cam follower 21 is supported on the first and second tables 22 and 23. The roller portion 21a of the cam follower 21 is engaged with the cam grooves 4a, 5a of the first and second cylindrical cams 4, 5. And
When the cylindrical cams 4 and 5 rotate, the cam grooves 4a,
The tables 22 and 23 reciprocate in the axial direction of the shaft 2 via the roller portion 21a of the cam follower 21 that engages with the shaft 5a.

The stroke X of each of the tables 22 and 23
1 is determined by the displacement X0 (see FIG. 3) of the cam grooves 4a and 5a (X0 = X1). Next, the operation of the device configured as described above will be described.

First, the interval between the first and second tables 22 and 23 is set according to the required size. At this time,
If the distance between the tables 22 and 23 at the movement start position is narrower than a predetermined value, first, the bolt 17 is loosened and the rubber pad 2
Separate 0. Next, the other bolt 16 is tightened, and a pressing force is applied to the pressed portion 13 via the rubber pad 20. As a result, the cam position adjustment table 11 moves along the rail 9 by an amount corresponding to the distance in which the bolt 16 is tightened via the pressing portion 13. As a result, the first cylindrical cam 4 moves in the same direction via the regulating roller 12.

Accordingly, the traverse position of the first table 22 is shifted to the left in the figure from before the adjustment, so that the first and second
The interval between the traverse ranges of the tables 22 and 23 can be widened. To narrow the traverse ranges of the first and second tables 22 and 23, the bolts 16 and 17 may be moved in the opposite direction.

Therefore, in this embodiment, the bolts 16 and 17
Only by moving the first and second tables 22 and 22,
The intervals of the 23 traverse ranges can be adjusted.
As a result, work efficiency can be greatly improved.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG. In this embodiment, the same members as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

Brackets 3 are provided before and after the lower surface of the plate 8.
Reference numerals 1 and 32 are attached and fixed, respectively. A guide shaft 33 is supported and fixed at an upper portion between the brackets 31 and 32. A chuck device 34 driven by a solenoid is supported on the guide shaft 33 so as to be relatively movable in the axial direction.

When electric power is not supplied, the chuck device 34 operates a brake (not shown) to hold the guide shaft 33 so as to be held in a state in which the chuck device 34 cannot move relative to the guide shaft 33. On the other hand, when the electric power is supplied, the operation of the brake is released and the relative movement with respect to the guide shaft 33 is maintained.

Below the portion of the brackets 31, 32 supporting the guide shaft 33, a screw shaft 35 having a thread groove for a ball screw threaded on the outer periphery.

As a result, the ball nut 36 is moved to the left or right in the drawing with the rotation of the screw shaft 35, and accordingly, the cam position adjustment table 37 fixed to the hanging portion 38 also moves in the same direction.

As a result, the position of the first cylindrical cam 4 is moved forward or backward by the moving amount of the cam position adjusting table 37, and the traverse position of the first table 22 can be shifted by a distance corresponding to the moving amount. . That is, the intervals between the traverse ranges of the tables 22 and 23 can be adjusted.

After the adjustment of the traverse position of the first table 22 is completed, the supply of electric power to the chuck device 34 is stopped to operate the brake so that the traverse position of the first table 22 does not deviate from the position. .

As described above, in this embodiment, in addition to the effects of the first embodiment, the first motor is driven by the power of the pulse motor M.
The traverse position of the table 22 can be adjusted. As a result, the traverse position of the first table 22 can be adjusted more quickly than in the first embodiment, and fine adjustment can be performed, so that work efficiency can be further improved.

In this embodiment, the movement of the cam position adjustment table 37 is restricted by the brake operation of the chuck device 34 except when the traverse position of the first table 22 is adjusted. As a result, the reaction force of the first table 22 received by the first cylindrical cam 4 is reduced by the guide shaft 33.
And a chuck device 34, and a screw shaft 35
And the ball nut can be prevented from being damaged. Further, it is possible to prevent the traverse position of the first table 22 from shifting after the adjustment of the traverse position.
