Automobile U-shaped bolt correction tool

Abstract

The invention discloses an automobile U-shaped bolt correction tool. A bottom plate is included. A correction sliding groove is formed in the outer wall of the top of the bottom plate. Correction plates are in sliding connection to the two sides of the inner wall of the correction sliding groove. Correction holes are formed in the outer walls of the tops of the correction plates. Air supply pipesare fixed to the tops of the outer walls of the opposite sides of the two correction plates through screws. The outer walls of the tops of the air supply pipes and the outer walls of the sides makingcontact with the correction plates are provided with air outlet holes. A connecting rod is connected to the inner walls of the two correction plates through hinges. A hydraulic cylinder is fixed to the outer wall of the top of the bottom plate through screws. One end of a piston rod of the hydraulic cylinder is connected to one end of the connecting rod through a hinge. By means of the automobileU-shaped bolt correction tool, a U-shaped bolt can be heated and subjected to heat preservation in the correction process, the possibility of U-shaped bolt fracture damage can be better reduced, the stability of the U-shaped bolt in the correction process can be improved, the U-shaped bolt correction quality can be better improved, and the automobile U-shaped bolt correction tool is suitable for different specifications of U-shaped bolts.

Description

technical field [0001] The invention relates to the technical field of correction devices, in particular to a U-bolt correction tool for automobiles. Background technique [0002] U-shaped bolts are easily deformed due to quenching and other reasons, so it is necessary to correct the U-shaped bolts to make the U-shaped bolts meet the production standards. At present, the correction of the U-shaped bolts is carried out on the punching machine. First, heat the deformed part after heat treatment. , and then use special tools for correction. [0003] After retrieval, the Chinese Patent Publication No. CN205165435U discloses a correction machine for rapid shaping of U-bolts in automobiles, including an operation table, a workbench and a hydraulic cylinder assembly, and the workbench includes a central movable part And the left and right symmetrical fixed parts, the central movable part is connected to the hydraulic cylinder assembly, the device fixes the U-bolt inside the correc...
