Clamping and fixing device for automobile welding

Abstract

The invention discloses a clamping and fixing device for automobile welding, and belongs to the technical field of automobiles. The clamping and fixing device comprises a protection box, wherein a first support plate is fixedly connected between the left and right inner walls of the protection box, a forward and reverse rotation motor is fixedly connected to the lower interior of the protection box, a first mounting hole is formed in the lower end of the first support plate, the output end of the forward and reverse rotation motor movably penetrates through the first mounting hole, the outputend of the forward and reverse rotation motor is fixedly connected with a worm, a threaded rod is rotatably connected between the left and right inner walls of the protection box, a worm gear is fixedly connected to the surface of the threaded rod, and the worm is meshed with the worm gear; and the threaded rod is located at the upper part of the first support plate, the surface of the threaded rod is in threaded connection with two nuts, and the upper ends of the two nuts are fixedly connected with connecting rods. Finally an automobile part to be welded can be clamped by two clamping platesthrough a simple transmission structure, so that the welding efficiency of workers is improved, and the working efficiency is further improved.
