Screw-in electric bottom fire explosion-proof tightening machine

Abstract

The invention belongs to the field of assembly of small-caliber bullets, and in particular relates to a screw-in type electric primer explosion-proof screwing machine used in the assembly of small-caliber bullets. A screw-in type electric primer explosion-proof tightening machine of the present invention includes a cartridge cup, a jacking mechanism, a positioning and clamping mechanism, a pit device for automatically pressurizing and searching for a screw-in type electric primer, an air circuit system, a control part and controlling software. The jacking mechanism of the screw-in electric primer explosion-proof screwing machine is installed on the machine base, the cartridge cup is located above the jacking mechanism, and the positioning and clamping mechanism, automatic pressurization and the pit device for finding the screw-in electric primer are located in the cartridge in turn. The top of the cylinder cups are installed on the rack. The air source, valve, air pipe and the pneumatic actuators of the above mechanical parts form an air circuit system. The control software is set in the controller of the control part, and the controller and the control software control the operation of the above-mentioned mechanical structure. The screw-in electric primer explosion-proof tightening machine of the present invention can automatically complete the screwing of the screw-in electric primer, it solves the problem of automatically finding the pit on the screw-in electric primer, and can ensure the precision control of the screw-in electric primer tightening depth , to ensure product quality, realize the separation of man and machine, and ensure the safety of production personnel.

Description

Screw-in electric bottom fire explosion-proof tightening machine technical field The invention belongs to the field of assembly of small-caliber bullets, and in particular relates to a screw-in type electric primer explosion-proof screwing machine used in the assembly of small-caliber bullets. Background technique The production of small-caliber ammunition is mostly manual assembly. The worker uses a vise to clamp the cartridge, and snaps the wrench with three claws into the three pits distributed at 120° on the front surface of the electric primer, and then rotates the wrench to press down while rotating. , to achieve the purpose of tightening the electric primer. This manual assembly method is not only labor-intensive for workers, but also the screw-in torque and screw-in depth cannot be controlled, and the dispersion is also large. If there is a slight carelessness in screwing in, the electric primer will explode, causing injury accidents. Contents of the invention ...
