Welding and fixing device for pipe end clamp of automobile pipe fittings

Abstract

The invention discloses a pipe end hoop welding and fixing device for an automobile pipe, and belongs to the field of automobile pipe end machining equipment. The device comprises a worktable, a pipe head positioning plate and clamps, wherein the pipe head positioning plate and the clamps are fixed to the worktable. The pipe head positioning plate is provided with a pipe limiting groove and a hoop limiting groove. The clamps comprise a hoop clamp, a lateral pushing pipe clamp and an annular hoop pipe clamp, wherein the hoop clamp can press a hoop arranged outside the automobile pipe in a sleeving mode to the interior of the hoop limiting groove; the lateral pushing pipe clamp is used for pushing the automobile pipe to the interior of the automobile pipe limiting groove to be pressed; the annular hoop clamp is used for clamping and positioning the automobile pipe. The positions of the three clamps are adjustable. The automobile pipe limiting groove and the hoop limiting groove form a step type annular groove. By means of the pipe end hoop welding and fixing device, the pipe end of the automobile pipe and the hoop can be precisely positioned, the pipe end and the hoop can not deviate in the machining process, clamping marks can not be generated on the automobile pipe, and the automobile pipe can not be damaged.

Description

technical field [0001] The invention relates to a processing equipment for pipe ends of automobile pipe fittings, in particular to a clamp welding and fixing device for pipe ends of automobile pipe fittings. Background technique [0002] At present, when the pipe ends of automobile pipe fittings are welded with the clamps, it is necessary to fix the position of the automobile pipe fittings and clamps. Now, mechanical clamps are generally used for positioning, because the automobile pipe fittings are hollow casings with large diameters, and mechanical clamps are used. When positioning, if the force of the clamp is strong, it is easy to deform and dent the clamp of the automobile pipe fitting. If the force of the clamp is light, the relative position between the pipe end of the automobile pipe fitting and the clamp is easy to shift, and the clamp and the pipe end of the automobile pipe fitting are accurate. The welding forming position is that the pipe end of the automobile pi...

[0002] At present, when the pipe ends of automobile pipe fittings are welded with the clamps, it is necessary to fix the position of the automobile pipe fittings and clamps. Now, mechanical clamps are generally used for positioning, because the automobile pipe fittings are hollow casings with large diameters, and mechanical clamps are used. When positioning, if the force of the clamp is strong, it is easy to deform and dent the clamp of the automobile pipe fitting. If the force of the clamp is light, the relative position between the pipe end of the automobile pipe fitting and the clamp is easy to shift, and the clamp and the pipe end of the automobile pipe fitting are accurate. The welding forming position is that the pipe end of the automobile pipe fittings should exceed the clamp by 0.5mm, and the precision requirement is high. If the mechanical clamp positioning method is used, if the force is light, it will affect the axial processing accuracy, and due to the action of the electrode during the welding process, it will also cause peripheral Offset
