[0008] By adopting the above technical solution, when the lifting seat descends to the lowest position, the weight of the counterweight block will drive the top rod to sag. The rubber column is provided to reduce the wear of the inner wall of the groove.

[0009] The utility model is further configured as follows: the base comprises an upper seat, a lower seat, and a connecting column located between the upper seat and the lower seat; a plurality of guide holes are opened on the upper seat, and the upper pressure seat passes through the guide holes.

[0010] The utility model is further configured as follows: the lifting seat is located between the upper seat and the lower seat.

[0011] The utility model is further configured as follows: the upper pressure seat comprises a seat body, a pressure head fixed at the upper end of the seat body, and the lower end of the seat body is fixed to the lifting seat.

[0012] The utility model is further configured as follows: the cross section of the seat body is rectangular.

[0013] The utility model is further configured as follows: the lifting drive device is a cylinder and is located between the upper seat and the lower seat.

[0014] The utility model is further configured as follows: the cylinder body is fixed to the upper end surface of the lower seat, and the cylinder piston rod is fixed to the lifting seat.

[0015] The utility model is further configured as follows: the upper seat is provided with a strip hole, and the lifting member passes through the strip hole.

[0016] By adopting the above technical solution, the strip-shaped hole can limit the movement range of the lifting member and prevent the lifting member from deflecting left and right.

[0017] The utility model is further configured as follows: an inclined material guide groove is provided on the base, and the material guide groove is located at one side of the lower positioning seat.

[0018] By adopting the above technical solution, the workpiece dropped after the lower positioning seat is flipped over enters the material guide groove and slides downward along the material guide groove.

[0019] The beneficial effect of the utility model is that after the drilling process is completed, the upper pressure seat of the positioning mechanism of the utility model rises, and while the workpiece is released, the lower positioning seat also flips to guide the workpiece into the material guide groove, and it does not need to be removed manually or by a robot. It has the effect of automatic unloading after drilling processing, simple structure, and easy manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS
