Pipe fixing device for pipe welding machine

Abstract

The invention discloses a pipe fixing device for a pipe welding machine. The pipe fixing device comprises a fixed base; bumps are fixedly connected to the bottoms of the left side surface and the right side surface of the fixed base; a fixed clamping block is fixedly connected to the upper surface of the fixed base; electric push rods are fixedly connected to the left side and the right side of the upper surface of the fixed base by means of fixed blocks; connecting blocks are fixedly connected to the top ends of the two electric push rods; and a movable seat is fixedly connected between the opposite side surfaces of the two connecting blocks. Through the mutual cooperation of the fixed base, the fixed clamping block, the electric push rods, the connecting blocks, the movable seat, a movable groove, sliding rods, movable blocks, strong springs and a movable clamping block, a welding pipe is flexibly clamped, the surface of the clamping pipe is effectively prevented from being damaged,the problem that in an existing pipe fixing device for a pipe welding machine, the surface of the pipe is damaged due to rigid clamping is solved; and through the mutual cooperation of noise reductionrings, an elastic noise reduction gasket and protecting friction layers, the problem that when a fixing device is used, high noise is generated is solved.

Description

technical field [0001] The invention relates to the technical field of welded pipe machines, in particular to a pipe fixing device for welded pipe machines. Background technique [0002] With the development of industry, industries such as automobiles, home appliances and petroleum require more precise welded pipes, and the requirements for dimensional tolerances of welded pipe products are getting higher and higher. Processing accuracy and other factors are related. When the welded pipe machine is processed, the steel plate is usually bent and rolled, and then the longitudinal seam is welded to form a pipe body with a closed side wall. When welding, the two sections of the pipe to be welded are Put it into the pipe welding machine, and then weld the two sections of pipes through the welding device. [0003] When the pipe welding machine welds the pipe, it needs to clamp and fix the pipe. The existing pipe fixing device of the pipe welding machine is generally manual clampi...
