Abstract

The invention belongs to the technical field of machining equipment for automobile parts, and particularly discloses a correction mold for an automobile rear axle housing. The correction mold for the automobile rear axle housing comprises an upper mold holder and a lower mold holder. An intermediate plate is arranged between the upper mold holder and the lower mold holder. A plurality of guide columns are arranged on the lower mold holder. Guide holes corresponding to the guide columns in position and number are formed in the intermediate plate, and guide holes corresponding to the guide columns in position and number are also formed in the upper mold holder. A plurality of upper correction blocks which are slidably connected with the upper mold holder are arranged at the lower end of the upper mold holder. A plurality of lower correction blocks which are slidably connected with the lower mold holder are arranged at the upper end of the lower mold holder. A plurality of upper positioning blocks which are slidably connected with the intermediate plate are arranged at the upper end of the intermediate plate. A plurality of lower positioning blocks which are slidably connected with the intermediate plate are arranged at the lower end of the intermediate plate. The upper correction blocks, the lower correction blocks, the upper positioning blocks and the lower positioning blocks are provided with control valves used for controlling sliding of the upper correction blocks, the lower correction blocks, the upper positioning blocks and the lower positioning blocks correspondingly. Compared with the prior art, the correction mold has the advantages that the using process is simple, the correction efficiency is high, and damage to the rear axle housing is effectively prevented in the correction process.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing equipment, and in particular relates to a correction mold for an automobile rear axle housing. Background technique [0002] The car drive axle is generally composed of the final drive, differential, wheel drive and drive axle housing. Its function is to bend the power transmitted by the universal transmission device through a 90° angle, change the direction of force transmission, and reduce the speed by the main reducer. After increasing the torque, it is distributed to the left and right half shafts and the drive through the differential. wheel. The drive axle housing is divided into integral axle housing and segmented axle housing, and the integral axle housing is mainly the rear axle housing. When the rear axle housing is in use, the end faces on both sides and the inner end face will receive relatively large stress, which will cause deformation and affect the reliability of th...
