The invention discloses a shaft part bending correcting device and a using method thereof, and belongs to the technical field of shaft part machining.The shaft part bending correcting device comprises a support base, a correcting support is fixedly installed on the top of the support base, a hydraulic cylinder is fixedly installed on the correcting support, and a hydraulic pressure gauge is arranged on the hydraulic cylinder; two V-shaped supporting blocks and a dial indicator support are installed on the top of the support base in a sliding mode, a dial indicator is installed on the dial indicator support, the dial indicator support and the dial indicator are both located between the two V-shaped supporting blocks, and a manual hydraulic pump connected with the hydraulic cylinder is installed on the correction support. On the basis of cold pressing correction, accurate measurement of the bending amount of the shaft part is completed at a time, accurate control over the correction amount during cold pressing correction is achieved, and therefore the bending correction efficiency and correction effect of the shaft part are improved.
Description
technical field [0001] The invention relates to the field of shaft parts processing technology, in particular to a bending correction device for shaft parts and a use method thereof. Background technique [0002] After the heat treatment of steel parts, under the combined action of thermal stress and structural stress, the deformation of the parts occurs, and only proper correction can meet the design requirements of the process. [0003] When the bending amount of the shaft parts exceeds the design requirements, it needs to be straightened. There are generally two methods of cold state correction: twisting bar beating straightening and cold pressing straightening. Among them, the cold pressure correction is to support the main journals at both ends of the shaft on the press with V-shaped blocks, and place an aluminum or copper skin between the pressure rod of the press and the crankshaft, and then align the shaft in the opposite direction of the shaft bending. Apply pressu...
