After the wrench 1 moves to the position of the positioning fixture 5 and each positioning surface 503 of the three-bending positioning block 502 is attached to the corresponding working surface 103, the sensor 8 on the three-bending positioning block 502 can feed back information to the control system, and the control system sends out instructions and gradually controls the upper clamping screw 504, the lower clamping screw 505 and the upper clamping screw and the lower clamping screw and the limiting of the side top block 508 on the outer side of the wrench 1, so that the orderly clamping and positioning of the head 101 of the wrench 1 by the positioning fixture 5 is ensured, and the reliability of operation is improved.
Referring to fig. 6, the drilling device 7 includes a drill 701, the drill 701 is telescopically disposed on a drill base 702, and the bottom of the drill base 702 is fixedly connected with the workbench 6; the drill bit base 702 is further provided with a linear motor 703 and a rotary motor 704, the linear motor 703 is used for driving the drill bit 701 to linearly move, and the rotary motor 704 is used for driving the drill bit 701 to rotate.
The drilling device 7 according to the above embodiment of the present invention has a drill 701 for drilling processing telescopically mounted on a drill base 702 and driven to move telescopically by a linear motor 703. When the head 101 of the wrench 1 moves to the positioning fixture 5 and is clamped and positioned, the linear motor 703 drives the drill bit 701 to extend and move to the drilling position of the head 101 of the wrench 1 on the positioning fixture 5, and then the rotary motor 704 drives the drill bit 701 to rotate, so as to drill the head 101 of the wrench 1. When the drilling is completed, the rotation of the rotation motor 704 is stopped, and then the linear motor 703 drives the drill 701 to retract to the drill base 702, so that the drilling of the wrench 1 is completed.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
