Cracking processing equipment and processing method for bearing seat of main reducer housing of medium and heavy vehicles

Abstract

The invention provides fracture splitting machining equipment and a machining method for main speed reducer shell bearing seats of medium and heavy vehicles. The fracture splitting machining equipment comprises a base, an operation rack, a shell positioning mechanism, a fracture splitting mechanism, a back pressure mechanism and a bolt fixed-torque assembly mechanism. The shell positioning mechanism is positioned at one end of the base and used for positioning a to-be-machined workpiece; the back pressure mechanism is erected above the to-be-machined workpiece to apply a back pressure; the fracture splitting mechanism is arranged above the base and used for applying fracture splitting machining to the to-be-machined workpiece; the bolt fixed-torque assembly mechanism is in abreast arrangement with the back pressure mechanism and used for reset mounting of the workpiece subjected to fracture splitting machining. By the fracture splitting machining equipment for the main speed reducer shell bearing seats of the medium and heavy vehicles, a process from fracture splitting to assembly of the bearing seats and bearing covers can be realized directly. Compared with existing fracture splitting equipment with batch production restricting factors such as assembly, resetting, bolt screwing and the like after fracture splitting carried out manually or by adoption of other devices, the fracture splitting machining equipment has the advantage that integration of fracture splitting and assembly of the main speed reducer shell bearing seats is truly realized, so that obstacles are cleared away for batch production.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing, and in particular relates to cracking processing equipment and a processing method for a housing bearing seat of a main reducer of a medium-heavy vehicle. Background technique [0002] The main function of the main reducer housing of medium and heavy vehicles is to support the driving and driven bevel gears so that they mesh accurately and keep them reliable and stable during the working process. The correct meshing of the gears is closely related to the processing quality and assembly of the gears, the rigidity of the main reducer housing, and the support rigidity of the gears. In order to ensure the running performance and service life of the gear, it is required that the bearing seat and the bearing cover supporting the gear have extremely high positioning accuracy during assembly. The bearing seat of the main reducer housing is composed of two sets of bearing seats and bearing ...
