[0050] Specifically, the free end of the connecting rod 38 is provided with a baffle 39, which allows the bolt 33 to not directly separate from the positioning fixture 2 after the threaded end of the bolt 33 is disengaged from the screw hole 37, facilitating the subsequent rapid pressing of the workpiece 23 and serving to store the bolt 33; the baffle 39 is slidably disposed in the guide groove 391, which ensures that the bolt 33 is always aligned with the screw hole 37, avoiding the problem of stripping the screw during subsequent screw tightening and improving the stability of screw tightening; the connecting rod 38 is smaller than the diameter of the bolt 33, which allows it to be offset to a certain extent, thereby causing the pressure block 31 to be offset, making it easier to place the workpiece 23 in the positioning groove 22.

[0051] Usage process

[0052] The workpiece 23 is placed in the positioning groove 22 on the positioning fixture 2. A placement channel for the workpiece 23 is provided between the pressure block 31 and the positioning fixture 2. First, the spring 36 plunger 27 is pushed on one side of the workpiece 23. The spring 36 plunger 27 presses the workpiece 23 against the positioning groove 22. At the same time, the workpiece 23 is located on the pad 24 and its position is limited by the contour groove on the pad 24. The bolts 33 on the pressure block 31 are rotated one by one so that the pressure ends 32 on both sides of the pressure block 31 press and position the workpiece 23 on the positioning groove 22, realizing the synchronous positioning of the workpiece 23 on the two positioning grooves 22. The two pressure blocks 31 are arranged opposite each other on both sides of the two positioning grooves 22. Each workpiece 23 can be positioned and clamped on both sides by two pressure blocks 31, which further ensures the positioning effect of the workpiece 23 and avoids positional deviation during processing. After all workpieces 23 are clamped on the positioning fixture 2, the positioning fixture 2 loaded with workpieces 23 is transported to the reference table 11. The positioning pin 12 on the reference table 11 is locked in the limiting groove 13 of the positioning fixture 2, and the positioning rod passes through the pin hole 14 of the positioning fixture 2 to achieve rapid positioning of the positioning fixture 2. The lever clamping cylinder 41 drives the clamping block 42 to press the positioning fixture 2 on the reference table 11, thereby completing the rapid positioning of the positioning fixture 2 and improving processing efficiency.
