Description

Clamp holder

The invention relates to a related device of a processing tool; in particular to a clamp die holder having a positioning plate.

Referring to FIG. 1 , a common clamp mold base is mainly composed of a base 1 and a joint base 2; a surface of the base 1 protrudes from a plurality of positioning blocks 1a, and the joint base 2 has a plurality of positioning slots. 2a, and the positioning groove 2a is based on the simplicity of the processing, and is represented by a circular hole. In the assembly, the positioning block 1a of the base 1 is inserted into the positioning groove 2a of the coupling seat 2 to complete the positioning assembly.

In order to facilitate the alignment assembly and the processing margin relationship between the positioning block 1a and the positioning groove 2a, a gap is reserved between the positioning block 1a and the positioning groove 2a after the fitting. In particular, when the rectangular positioning block 1a is disposed with the circular positioning groove 2a, the gap is more remarkable. However, the presence of the gap tends to cause the base 1 and the joint 2 to loosen after assembly. Therefore, it is known that a metal positioning plate 3 and a spacer 4 are attached to the joint 2 to correct and stabilize the joint of the base 1 and the joint 2.

As shown in FIG. 2, FIG. 3 and FIG. 4, the positioning plate 3 is provided with a plurality of rectangular openings 3a, and the spacer 4 is provided with a plurality of openings 4a for facilitating the passage of the positioning blocks 1a. Further, the width w1 of each of the positioning blocks 1a is greater than the width w2 of the respective opening 3a, so that the positioning block 1a and the positioning groove 2a are pressed around the opening 3a of the positioning plate 3 by the positioning block 1a before the alignment of the positioning groove 2a. And the positioning plate 3 is moderately deformed to clamp the positioning block 1a, and guide the part of the joint portion of the positioning block 1a to be smoothly inserted into the positioning groove 2a.

However, the combination of the rectangular positioning block 1a, the circular positioning groove 2a, and the positioning block 1a combined with the segment width w1 being larger than the width w2 of the opening 3a will result in the following deletions: 1. The rectangular periphery of the opening 3a of the positioning plate 3 is The distance S1 between the circular arc-shaped peripheral edges of the circular positioning groove 2a is different, so that the positioning plate 3 is liable to cause wavy wrinkle deformation when pressed by the positioning block 1a. 2. The maximum distance from the periphery of the opening 3a to the circular arc-shaped periphery of the circular positioning groove 2a is prone to plastic deformation (Plastic deformation) which cannot be restored due to the external force of the positioning plate 3 exceeding a certain limit. . 3. The distance S2 between the wall surface of each positioning block 1a and the circular arc-shaped circumference of the circular positioning groove 2a is different, so that the gap between the positioning block 1a and the circular positioning groove 2a is also inconsistent, so that it cannot be formed. Tightly configured relationship. 4. Referring to FIG. 2 and FIG. 4, it can be seen that the diameter Φ of the circular positioning groove 2a is larger than the width w2 of the opening 3a of the positioning plate 3, in other words, when the base 1 is combined with the coupling seat 2, the positioning is performed. The block 1a only needs to be slightly pressed against the positioning plate 3, and the periphery of the opening 3a of the positioning plate 3 is easily deformed toward the groove bottom direction of the positioning groove 2a, which may cause plastic deformation which cannot be restored to the original state; the above situation is easier. In a state where the susceptor 1 or the yoke 2 is subjected to a lateral outward force, the positioning block 1a which is subjected to an external force is caused to collide with the peripheral edge of the opening 3a on the left and right sides.

It can be seen from the above that whether the positioning plate 3 is deformed by extrusion at the periphery of the opening 3a or permanent plastic deformation due to the external force exceeding the limit, the positioning effect of the positioning plate 3 is degraded, which is disadvantageous. Repeatedly used many times.

In view of the above, an object of the present invention is to provide a clamp mold base which not only makes the assembly effect more accurate and accurate, but also reduces the chance of permanent plastic deformation of the positioning plate and can be reused.

The third width W3 is smaller than the first width W1.

In addition, the clamp die holder 100A has a limiting means for limiting the amount of deformation of the positioning plate 24 subjected to the deformation deformation of the positioning block 14 at the periphery of the opening 28 not exceeding the critical value of plastic deformation.
