Abstract

PROBLEM TO BE SOLVED: To surely position and hold a work in a short time by providing a work installation part for positioning and holding the work in the axially right-angled direction and also positioning and holding it in the axially rotating direction. SOLUTION: A machining jig 10 forms a work mounting part 10A by the work receiving seat of a work positioning tool 11 and a work rotation preventive tool 12 in the state where the work rotation preventive tool 12 is fixed to the work positioning tool 11 by a bolt 14. The held part 1B of a work 1 is installed to a work installation part 10A so that a flat part 1C provided on a part of the outer circumference of a held part 1B continued to a work body part 1A is coincided with the work rotation preventive tool 12 within the work installation part 10A, so that the work 1 can be positioned in both the axially right-angled direction and the axially rotating direction. According to this, the work 1 can be surely positioned and held in a short time in both the axially right-angled direction and the axially rotating direction only by installing it to the work installation part 10A of the machining jig 10 set in a vice 100.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a processing jig.

[0002]

2. Description of the Related Art When a workpiece such as a mold part is cut by, for example, a milling machine, the workpiece is positioned and held in a vice fixed on a table. At this time, when mass-producing the same work, it is necessary to position the work each time the same work is mounted and removed one by one in a vise.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to reliably position and hold a work in a short time.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a processing jig which can be set in a vise, and which positions and holds a work in a direction perpendicular to an axis and positions and holds the work in a rotational direction around an axis. This is provided with a mounting portion.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 4 and 5, a processing jig 10 positions and holds a work 1 while being set on a vise 100 fixed to a table of a milling machine, for example. The top end side or the side surface of the workpiece 1 can be processed by the processing tool 2, and the end surface or the side surface of the work 1 on the back side can be processed by the processing tool 2.

At this time, the processing jig 10 is shown in FIGS.
As shown in the figure, the work positioning tool 11, the work stopper 12 and the work holder 13 are provided.

[0007] As shown in FIG. 1, the work positioning tool 11 has a flat portion 1 held on both outer surfaces by a vice 100.
1A, 11A, and a work accommodating hole 11B for accommodating the main body 1A of the inverted work 1;
A work seat 1 is provided around the opening of the work accommodation hole 11B.
1C. The work positioning tool 11 further includes a notch 11D for fitting the work stopper 12 at a part (two positions) of the outer periphery of the work receiving seat 11C.
2 is fitted with the work rotation stopper 12 shown in FIG. Further, the work holding member 13 also has flat portions 13A, 13A sandwiched by the work positioning member 11 on both outer surfaces (the width of the flat portions 13A, 13A is equal to the width of the flat portions 11A, 11A of the work positioning member 11). The same as the surface width).
It can be fixed to the upper end surface around C by a bolt 15.

Thus, the work jig 10 is mounted on the work positioning tool 11 with the work rotation stopper 12 fixed by the bolt 14.
A work mounting portion 10A is formed by C and the work rotation stopper 12, and a flat portion 1C provided on a part of the outer periphery of the flange-shaped held portion 1B connected to the main body 1A of the work 1 is attached to the work in the work mounting portion 10A. The held portion 1B of the work 1 is moved to the work mounting portion 10A so as to match the rotation stopper 12.
By mounting the work 1, the work 1 can be positioned and held both in the direction perpendicular to the axis and in the direction of rotation about the axis. In the processing jig 10, the work 1 is fixed to the upper end surface of the work positioning tool 11 with the bolt 15, and the work 1 is pressed by the work presser 13 to press the end surface of the held portion 1 </ b> B of the work 1. It is retained in the axial direction and can be machined.

Therefore, when machining the top side of the work 1,
As shown in FIG. 4, the held portion 1B of the work 1 is mounted on the work mounting portion 10A of the processing jig 10 in the upright state of the work 1, and the end face of the held portion 1B of the work 1 is held by the work holding member. By pressing with 13, the workpiece 1 is positioned and held, and can be processed by the processing tool 2.

When the work 1 on the bottom side is machined, as shown in FIG. 5, the work 1 on which the work on the top side has been completed is once removed from the work mounting portion 10A of the working jig 10, and then the work 1 is removed. In a state where the main body 1A of the work 1 is inverted and housed in the work housing hole 11B of the work positioning tool 11, the held part 1B of the work 1 is moved to the processing jig 10
By mounting the work 1 on the work mounting portion 10A and pressing the end surface of the held portion 1B of the work 1 with the work holding member 13,
The work 1 can be positioned and held, and can be processed by the processing tool 2.

Therefore, according to the present embodiment, the following operational effects are obtained. (Effects Corresponding to Claim 1) The work 1 is simply mounted on the work mounting portion 10A of the processing jig 10 set in a vise 100 fixed to a table of a milling machine, for example, and is perpendicular to the axis. Direction and rotational direction about the axis, it is immediately and reliably positioned and held in a short time. Therefore, when mass-producing the same work 1, the same work 1 is simply placed one by one in the work mounting section 1.
The work 1 can be positioned simply by attaching and detaching it to 0A, and productivity can be improved.

(Operation and Effect Corresponding to Claim 2) When the above-mentioned work 1 is processed from the top surface side and the bottom surface side, the held portion 1B is attached to the work mounting portion 10A in the upright state of the work 1. The workpiece 1 is positioned simply by being mounted, and the top side is machined.
Is turned upside down, and the held portion 1B is attached to the work mounting portion 10.
The work 1 can be positioned and processed on the bottom surface simply by simply mounting it on the work A.

[0013]

As described above, according to the present invention, the work can be positioned and held reliably in a short time.
