It is also called a fixture. In the mechanical processing manufacturing industry, positioning and clamping fixtures play a very important role. They ensure that the workpiece is always in the correct position relative to the machine tool, tool, etc., to ensure the consistency and quality of workpiece processing. Different types of workpieces have different requirements for clamping fixtures. In order to improve the efficiency of mechanical processing, a locking fixture is needed, but the existing locking fixtures still have the following shortcomings:

[0003] For example, the utility model with application number 202322556695.9 discloses a bidirectional quick locking clamp for mechanical processing. The utility model has a bidirectional clamping function, can clamp the workpiece quickly and accurately, and improves production efficiency. The clamp has a compact structure and is easy to operate. It can be applied to various mechanical processing machine tools. A tapered sleeve is provided between the left clamp seat and the right clamp seat, which has a certain flexibility and reduces damage to the side wall of the workpiece. The clamp can be used for lathes, milling machines and other machine tools and has a wide range of applicability. However, similar to the comparative documents of the above-mentioned application, when the existing locking clamps are used, since most locking clamps only have the performance of single-sided clamping, the workpiece is easy to warp up and deviate from the positioning point during the clamping process, resulting in unstable workpiece processing accuracy, causing the practicality of the bidirectional locking clamp to decrease and the efficiency of use to decrease.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a two-way locking clamp is proposed. Utility Model Content

The output shaft of the servo motor 401 is connected to the bidirectional lead screw 402 through a coupling. The operation of the servo motor 401 drives the movable slider 403 arranged outside the bidirectional lead screw 402 to move accordingly, and causes the limit block 404 to move left and right inside the base 1 accordingly. At the same time, the inner size of the limit hole 405 opened inside the limit block 404 matches the outer size of the limit rod 406. Therefore, the stability of the limit block 404 during movement is increased by cooperating with the limit rod 406 through the limit hole 405, so that the movable slider 403 can move stably on the upper end of the base 1, and the movement of the two movable sliders 403 is used to lock and limit the workpiece to be processed, thereby improving the use efficiency of the locking fixture.

[0023] like Figures 1 to 3As shown, a clamping assembly 5 is disposed at the upper end of the movable slider 403, and the clamping assembly 5 includes a receiving block 501, a docking groove 502, a docking block 503 and a clamping block 504.
