The fixture comprises a fixture main body 1, wherein a plurality of upper positioning grooves 1.1 are uniformly distributed on the fixture main body 1, and the upper positioning grooves 1.1 are annular grooves recessed downwards from the front surface of the fixture main body 1; 4 lower positioning grooves 1.2 are symmetrically arranged around the upper positioning groove 1.1; the lower positioning groove 1.2 is an approximately triangular groove recessed downwards from the front surface of the tool main body 1; a lock hole B1.21 is arranged in the lower positioning groove 1.2 and is used for positioning and locking the lower body B of the workpiece.

The middle position of the annular groove of the upper positioning groove 1.1 is provided with a positioning ring 1.3.

The inner positioning ring 1.3 is of a convex structure, and the height of the inner positioning ring is consistent with that of the tool main body 1. Specifically, the upper positioning groove 1.1 is an annular groove with a certain width which is concave downwards on the plane of the tool main body 1, a part which is not processed downwards is arranged in the middle of the annular groove, and a positioning ring with a certain height is formed after the part is compared with the annular groove. Because the upper body A of the workpiece has a circular cylindrical structure (see figure 4 of the specification), the end part of the upper body A of the workpiece can be placed in the annular groove by adopting the structure of the upper positioning groove 1.1, the inner positioning ring 1.3 can fix the upper body A of the workpiece from the inside, and if the inner positioning ring 1.3 is not arranged on the upper positioning groove 1.1, the upper body A of the workpiece is not limited and fixed in the inside, so that the upper body A of the workpiece is easy to shift in position.

A through hole (not labeled) is formed in the center position of the positioning ring 1.3. In particular, the through hole is used for locking and positioning.

A plurality of lock holes a1.4 are uniformly distributed in the middle of the tool main body 1 and used for locking.

The lock hole a1.4 and the lock hole b1.21 are blind holes.

The tooling also comprises a pressing strip 2 and a positioning block 3 which are matched with the tooling main body 1 for use. Specifically, the pressing strip 2 is positioned and placed on the upper body A of the workpiece through the upper positioning groove 1.1 and then transversely pressed above the upper bodies A of 2 workpieces, and screws are adopted to penetrate the pressing strip 2 to the through holes, so that the upper bodies A of the workpieces can be fixed from above; when the lower workpiece body B is processed, the pressing bar 2 is also used and acts as described above;

The positioning blocks 3 are only matched and used when the upper body A of the workpiece is machined, the positioning blocks 3 are fixed on the tool main body 1 through the lock holes a1.4, so that the positioning blocks 3 are positioned between the two upper bodies A of the workpiece from the side surfaces, the upper body A of the workpiece is fixed from the side surfaces, the pressing strip 2 can be fixed with the positioning blocks 3 through screws at the middle position of the pressing strip 2, the pressing strip 2 is further fixed, and the fixing effect of the upper body A of the workpiece is ensured.

Further, during the processing of the lower workpiece body B, according to the structural characteristics of the lower workpiece body B, positioning is performed through four corners at one end of the lower workpiece body B (the structure of the lower workpiece body B is shown in fig. 5 of the specification), the four corners of the lower workpiece body B are respectively placed on the lower positioning groove 1.2, and then the lower workpiece body B is fixed from above through the pressing bar 2 as described above; the width of the workpiece lower bodies B is larger, and the mutual clearance between every two workpiece lower bodies B is small after the workpiece lower bodies B are installed, so that the fixing of one positioning block 3 is not needed from the middle; after the pressing bar 2 fixes the lower workpiece body B, the lower workpiece body B is fixed into the lock hole B1.21 through holes (not marked) on four corners of the lower workpiece body B by screws, so that the 4 corners of the lower workpiece body B are fixed except the pressing bar 2, and the lower workpiece body B is fixed.
