Part deformation correcting device and using method thereof

Abstract

The invention discloses a part deformation correcting device. The part deformation correcting device comprises a shell with an opening in one end, a correcting and checking assembly arranged inside the shell and an adjusting nut arranged outside the correcting and checking assembly in a sleeving mode, one end of the correcting and checking assembly is fixedly connected with the inner wall of the shell through a tension spring, the other end of the correcting and checking assembly penetrates through the opening end of the shell and then extends out of the shell, the adjusting nut and the shell are coaxially arranged, one end of the adjusting nut is in running fit with the opening end of the shell, and the inner wall of the adjusting nut is in threaded connection with the outer wall of the correcting and checking assembly. During correction, the adjusting nut is rotated in the forward direction relative to the shell to enable the correcting and checking assembly to retract, then the correcting device is placed inside a to-be-corrected part, and then the adjusting nut is rotated in the reverse direction to enable the correcting and checking assembly to extend till the two ends of the correcting device abut against the two sides of the inner wall of the to-be-corrected part respectively, and finally, the adjusting nut continues to be reversely rotated until the size of the to-be-corrected part meets the design requirement, correction is completed, the structure is simple, operation is reliable, and correction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of part deformation correction, and in particular relates to a part deformation correction device and a use method thereof, which are suitable for improving the efficiency of part deformation correction and verification. Background technique [0002] During the manufacturing process of precision slender parts, especially welded parts with slender grooves or shells, due to the existence of welding internal stress and poor rigidity during processing, large deformations are likely to occur, and the size of the parts does not meet the design requirements. Therefore, it is necessary to perform multiple corrections on welded parts with slender grooves or shells. Generally, hammering, vise clamping, manual straightening or straightening on a press are required. Although the straightening function can be achieved, the correction There are still obvious shortcomings in terms of calibration efficiency and convenience....
