PROBLEM TO BE SOLVED: To provide a workpiece working jig of a stage replacing system in particular used for deburring various workpieces of castings, for example, various parts of an automobile or used for removing a gate part, which is downsized and lightened to facilitate the replacement of the jig and prevent worked chips from being accumulated even when it is applied to a device for multikind workpiece in process. SOLUTION: A workpiece working jig of a stage replacing system in particular provided with a workpiece locating reference seat 2 to mount the workpiece 5 to be worked in a predetermined position, a workpiece pressing mechanism 3 to hold the workpiece 5 mounted on the reference seat 2 and a clamping mechanism 4 to clamp the workpiece 5 mounted on the reference seat 2 removes the workpiece pressing mechanism 3 from a jig X to provide an external mounting mechanism without mounting the mechanism 3 in the jig X, so that the jig can be downsized lightened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for processing a work, particularly a setup change method, which is used for deburring of a variety of cast workpieces or for removing a gate portion, and particularly to a miniaturized jig. The present invention relates to a work processing jig that has been reduced in weight.

[0002]

2. Description of the Related Art Various parts of an automobile, such as a cylinder head, a cylinder block, and an intake manifold, are manufactured by casting aluminum or iron. Since the cast product (work) obtained by this casting has burrs and gates, the work is stored and fixed in a jig and processed using a work processing device to eliminate these burrs and gates. Must.

Conventionally, this type of work processing jig has been
The structure shown in FIG. 2 is known.

FIG. 2 is a perspective view of a conventional type of work processing jig. As shown, a work positioning reference seat 11 and a work pressing mechanism 12 are arranged on a mounting plate 10, respectively. And a work clamp mechanism 13.

In the conventional jig having the above-described structure, a workpiece 14 to be machined is determined and arranged at a predetermined machining position on a reference seat 11, and then the positioned workpiece 14 is pressed by a workpiece pressing mechanism 12, and a work clamp is provided. The workpiece 14 is stored and fixed on the reference seat 11 by being clamped by the mechanism 13.

The work 14 fixed on the reference seat 11 in this manner is not shown, but is subjected to a processing process for removing burrs and gate portions adhered during casting using a work processing apparatus. This processing is usually performed using a multi-type work in-process device using a setup change method.

[0007]

However, as shown in FIG. 2, the above-mentioned known jig has both the work pressing mechanism 12 and the work clamp mechanism 13 inside the jig, that is, on the mounting plate 10. , Not only the size is increased, but also the weight is increased,
For this reason, when applied to a multi-kind work in-process apparatus using the setup change method, the jig replacement operation is difficult, and further, there is a drawback that processing waste is accumulated on the mounting plate 10.

Therefore, the object of the present invention is not only to reduce the size, but also to reduce the weight, so that the jig replacement operation can be easily performed even if the invention is applied to a multi-type work in-process apparatus by a setup change system. An object of the present invention is to provide a workpiece processing jig in which the accumulation of debris is prevented and the disadvantages of the above-described known technology are improved.

[0009]

According to the present invention, there is provided a work positioning reference seat for mounting a work to be machined at a predetermined machining position, and a work positioning reference seat mounted on the reference seat. In particular, in a work processing jig using a setup change method, the work pressing mechanism includes a work pressing mechanism for pressing a work and a clamp mechanism for clamping a work placed on the reference seat. Instead of being attached to the jig, the jig is detached from the jig to form an external mechanism, thereby reducing the size and weight of the jig.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a specific example of a work processing jig according to the present invention, and FIG. 2 is a perspective view of a specific example of a conventional work processing jig.

As shown in FIG. 1, a work processing jig X according to the present invention includes a reference seat 2 disposed on a mounting plate 1.
, A work pressing mechanism 3 and a work clamp mechanism 4.

A work 5 to be machined is positioned and mounted on a reference seat 2 at a predetermined machining position.

This work 5 is a cast product with burrs and gates obtained by casting of aluminum or iron still attached,
For example, it is a rough part such as a cylinder head, a cylinder block, and an intake manifold of an automobile.

Work 5 positioned and mounted on reference seat 2
Then, the workpiece 5 is clamped by the work clamping mechanism 4 at any of a plurality of places, and is pressed by the work pressing mechanism 3 at any of the plurality of places as described above, whereby the work 5 is firmly stored on the reference seat 2. Fixed.

In the above-described jig X of the present invention, the work clamping mechanism 4 is mounted inside the jig X, that is, on the side of the mounting plate 1 as shown in FIG.
2 differs from the known jig of FIG. 2 in that the jig X is not mounted on the mounting plate 10 as shown in FIG.
And an external mechanism.

The work 5 housed and fixed at a predetermined working position on the reference seat 2 is not shown, but is subjected to a working process for removing burrs and gates adhering to the work 5 using a work processing apparatus. . In particular, the work processing jig according to the present invention is reduced in size and weight as described later, so that it can be easily applied to various types of work in-process devices by a setup change method, and can be used for processing various types of work. Used.

[0018]

As described above, the work processing jig of the present invention is detached from the jig without mounting the work pressing mechanism in the jig and is provided as an external mechanism. Therefore, only the work pressing mechanism is not provided in the jig. In addition, the mounting plate can be made smaller, so that the size can be reduced to one third of the size of the conventional jig having the work pressing mechanism in the jig, and the weight can be reduced. The jig replacement operation is easy even when applied to a multi-kind work in-process device by a replacement system.

Further, according to the present invention described above, since the mounting plate is made smaller, there is no possibility that machining chips are deposited on the mounting plate as in the prior art, and the work becomes easier from this point as well.
