Description

Vise structure with two-way clamping

The present invention relates to a clamp structure, and more particularly to a vise structure with two-way clamping that can improve the clamping effect.

According to the conventional fixture structure, as disclosed in the "Attachment of Two-Way Clamping Positioning Fixture Structure", which is approved by the Department of Economics on August 21, 1987, it mainly includes: The two abutting blocks are respectively formed with a tapered tapered surface on opposite sides of the two abutting blocks, and a pushing block having the same taper as the tapered mask is disposed between the tapered faces of the two abutting blocks. The upper part is provided with a bolt penetrating through the pushing block, and the two side surfaces of the abutting block providing spring are respectively provided with a spring bucking block for the spring to be hooked, and the side of the abutting block provided with the spring is provided with one side plate, respectively The side plate is convexly formed with a restriction strip that can abut against the spring. When the bolt is screwed into the through hole provided on the machine table, the head of the bolt can be used to drive the push block to move along with the cone surface of the push block to press and push the abutting blocks of the two tapered surfaces. Protruding toward both sides. In order to achieve the effect of clamping positioning on the work pieces on both sides at the same time, thereby achieving the use flexibility and performance of the overall use of the clamp.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: (1) The abutment block and the push block only form a contradiction with the tapered surface, so that the push block is screwed into the machine. When the table is pushed outwardly against the block, the workpiece is clamped. Since only three inclined faces are formed between the abutting block and the push block, there is insufficient contact area. When the screw lock is tight, the push block will be bolted. The positional displacement is caused to cause the workpiece to be obliquely pushed against the block, resulting in a decrease in clamping stability and smoothness.

(2) The spring is coupled to the two abutting blocks, and a side plate is disposed on a side of the spring, and the side plate is convexly provided with a limiting strip for providing a spring, and the limiting bar is only disposed above and below the spring. The edge is not blocked on the outer side of the spring, so that the spring may still fall off from the outer side. The side plate is not well protected against the spring.

(3) The abutting block and the pushing block form a contradiction only by the tapered surface, that is, only the two angles of the abutting surface, the anti-swaying effect is not good, and the lateral thrust generated by the external force cannot be fully cancelled. Therefore, there is a problem that the clamping stability is insufficient.

In view of this, this creation has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, this creation has a practical and practical creation.
