Embodiment 1

[0037] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, a centerless grinding and pre-pressing mechanism of a three-pin frame includes a workpiece 1 and a grinding machine equipment 2, and also includes a grinding assembly and a pressing assembly. The workpiece 1 is axially positioned and ground by an axial guide wheel assembly. , the workpiece 1 is adjustable for crimping through the pressing assembly.

[0038] The grinding assembly includes a guide plate 3, a grinding wheel 4 and a guide wheel 5, the bottom of the guide plate 3 is fixed to the grinding machine equipment 2, the workpiece 1 is arranged between the grinding wheel 4 and the guide wheel 5, and the guide wheel The rotation of 5 drives the workpiece 1 to rotate in reverse, and the grinding wheel 4 is reversely ground with the forwardly rotating workpiece 1, and the guide wheel 5, grinding wheel 4 and workpiece 1 are distributed in a mating manner;

[0039] The grinding machine equipment 2 is provided...

Abstract

The invention relates to a pre-pressing mechanism, in particular to a three-pin frame centerless grinding pre-pressing mechanism and an operation method thereof. The three-pin frame centerless grinding pre-pressing mechanism comprises a workpiece and grinding machine equipment and further comprises a grinding assembly and a pressing assembly, the workpiece is ground through an axial guiding wheelassembly, and adjustable compression joint is conducted on the workpiece through the pressing assembly. According to the three-pin frame centerless grinding pre-pressing mechanism and the operation method thereof, the structure is compact, the grinding precision is further improved, and the product quality is improved.

Description

technical field [0001] The invention relates to a pre-pressing mechanism, in particular to a centerless grinding pre-pressing mechanism of a tripod frame and an operation method thereof. Background technique [0002] The three-pin frame is the core component in the drive shaft assembly, and the drive shaft transmits the torque of the differential to the wheels. [0003] The three-pin frame originally adopts the method of process hole, which is completed by cylindrical grinding process. The process hole is processed in the stressed part, which has a certain influence on the product's performance and strength. In order to further reduce the risk of use and prevent the product from breaking and failing due to instantaneous loading under complex road conditions during use, the car will vibrate and make abnormal noise after failure, making it impossible to drive normally. However, the product structure is special, and it cannot be balanced and smooth, resulting in defects in pr...
