Abstract

(57) [Summary] [Purpose] When fixing a jig that holds a work on the bed of the assembly machine in the transfer machine, facilitate the centering work of the jig and the shaft head of the assembly machine. To [Structure] When fixing the jig holding the work to the mounting hole of the bed in the transfer machine with bolts,
In the centering device for centering the jig and the shaft head, the bed is provided with a mounting groove for reference fitting, and the distance between the rising surface of the mounting groove and the axis of the shaft head is set in advance. Keep it. A jig can be pressed against the reference pad fitted in the mounting groove for positioning.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a centering device in a transfer machine.

[0002]

[Prior Art]

 When assembling the parts on the transfer machine, the jig holding the work is fixed to the bed, but when fixing to the bed, the jig and the shaft head must be aligned accurately. In this alignment, the hole for inserting the bolt of the jig has been a burrow hole larger than the diameter of the bolt, and by using this burrow hole to finely adjust the mounting position of the jig on the bed, Accurate centering of the head.

[0003]

[Problems to be solved by the device]

 However, as mentioned above, the work of centering the jig while slightly moving it on the bed is not easy, and it takes a lot of time and skill to reduce the work efficiency of the transfer machine, and its improvement is strong. Was wanted. The present invention was made in order to solve such a conventional problem, and when the jig is fixed on the bed, it is possible to easily perform the centering work of the jig and the shaft head. An object is to provide a centering device for a machine.

[0004]

[Means for Solving the Problems]

 As a means for technically solving this problem, the present invention provides a jig and an assembling machine for fixing a jig holding a work to a mounting hole of a bed of the assembling machine in a transfer machine. In a centering device that is designed to perform centering with the shaft head, a mounting groove for reference fitting is provided on the bed, and the distance between the rising surface of the mounting groove and the axis line of the shaft head is set in advance. The gist is that the jig is pressed against the reference pad fitted in the mounting groove for positioning.

[0005]

[Work]

 When the jig is pressed against the reference pad fitted in the mounting groove of the bed, the center line of the jig and the axis line of the shaft head are aligned so that they can be centered. The positioning of can be done immediately.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, 1 is one of the assembling machines in the transfer machine, and is equipped with a shaft head 1a having an axis C in the vertical direction.

Reference numeral 2 is a jig for holding the work W. The lower end portion of the jig W is fixed to the mounting hole 3a of the bed 3 with the bolt 4, and the jig 2 can be easily positioned during this mounting. There is.

That is, a mounting groove 3b for fitting a reference pad 5 such as an edge locator is provided on the upper surface of the bed 3, and a rising surface 3c of the mounting groove 3b, that is, a surface with which the reference pad 5 abuts. Is set in advance so that the distance L from the shaft head 1a to the axis C of the shaft head 1a matches the distance from the end of the jig 2 pressed against the reference pad 5 to the center line of the jig. .

Therefore, if the jig 2 is placed on the bed 3 and its end is brought into contact with the reference pad 5, centering of the jig 2 and the shaft head 1a is immediately completed, and the jig 2 The attachment of the jig 2 is completed by inserting the bolt 4 into the bolt insertion hole 2a and screwing the bolt 4 into the mounting hole 3a of the bed 3.

The jigs 2 holding the work W are conveyed to the assembling machine one after another, but if all the assembling machines are fixed to the bed through the reference pad as described above, the positioning of the jigs 2 will be quick. Since it is completed with a seat, the laborious centering work with the shaft head as in the past is not necessary, and the work efficiency on the transfer machine can be significantly improved.

If necessary, it is possible to position the jig by using a reference pad in both the X-axis and the Y-axis, not only in the uniaxial direction.

[0012]

[Effect of the device]

 As described above, according to the present invention, when the jig holding the work is mounted on the bed, the end of the jig is brought into contact with the reference pad such as the edge locator fitted in the mounting groove of the bed. By doing so, the centering with the shaft head is completed immediately, so even an unskilled person can easily perform positioning in a short time, simplifying the work and improving the work efficiency. It has an excellent effect.
