Door bar countersunk spot welding machine

Abstract

The invention discloses a door strip counter bore spot welding machine. The door strip counter bore spot welding machine is characterized by comprising a base. A material carrying position, a counter bore position and a spot welding position are arranged on the base and are connected through a feed guide rail. A guide chute allowing a door strip to be embedded in and move in is formed in the feed guide rail. A feed cylinder used for pushing the door strip to move in the guide chute is arranged in the position, corresponding to the material carrying position, of the feed guide rail. A counter bore device used for processing counter bores in the door strip is arranged in the counter bore position. A spot welding device used for welding connecting feet to the door strip is arranged in the spot welding position. The door strip counter bore spot welding machine can conduct counter bore and spot welding processing on the door strip in an assembly line mode. The processing efficiency is greatly improved, and the product quality of the door strip is improved as well. Meanwhile, workers do not need to conduct operation manually in the production process, and possible damage to the workers in the production process is avoided to the maximum extent.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a door bar counterbore spot welding machine which can perform counterbore and spot welding operations on door bars. Background technique [0002] The door strip on the door lock is a very important component of the door lock, which is respectively connected with the door panel and the lock cylinder, so as to fix the door lock in the door panel. The door strip and the door panel are generally connected by screws. In order to prevent the screws from being exposed outside the door strip, it is necessary to counterbore the screw holes on the door strip. The current method of counterbore processing is generally performed by the operator using a desktop drilling machine to perform counterbore operation at the screw hole. The disadvantage of doing this is that manual operation has a certain safety risk for the operator, and the production efficiency is very low. The con...

Problems solved by technology

The current method of counterbore processing is generally performed by the operator using a desktop drilling machine to perform counterbore operation at the screw hole. The disadvantage of this is that manual operation has a certain safety risk for the operator, and the production efficiency is very low.

The connecting foot connecting the door strip and the lock cylinder is welded on the door strip by spot welding. Now the spot welding operation of the door strip is generally manually placed in the spot welding machine for spot welding. The disadvantage is that the operator must be very focused when operating. Once distracted, accidents are easy to occur, and once an accident occurs, the damage to the operator is very large, and the production efficiency is also very low.
