Embodiment 2

[0056] This embodiment discloses the welding process of the connecting block of the hydraulic torque converter cover wheel assembly using the fixture described in Embodiment 1, including the following steps:

[0057] 1) see Image 6 , the figure is a common standard torque converter top cover 7, the outer side of which is connected with a positioning column 9 and a connecting block 6. In the embodiment, the hydraulic torque converter top cover 7 is stamped, and then the positioning column 9 is welded at the center of the outer side 701 of the hydraulic torque converter top cover. The torque converter top cover 7 is a standard part on a common hydraulic torque converter, and its outer side will be connected with the positioning column 9 and the connecting block 6, and its inner side has a certain volume, and the inner end surface has an annular stop. The positioning column 9 is also a standard part on a common hydraulic torque converter, and is a cylindrical part. Since the h...

Abstract

The invention aims to provide a process for welding a covering roller assembly of a hydraulic torque converter. The process is characterized in that the process can implement an upward welding and / or turning machining face and is favorable for machining and batch production, a connection block, a centering block and the covering roller assembly can be finished after being welded, and the problem of size precision is solved. The process comprises the following steps: a, stamping the covering roller assembly of the hydraulic torque converter; b, machining a positioning block which leaves some margin, c, welding the positioning block in the center of the outer surface of the covering roller assembly, d, welding the connection block on the outer surface of the covering roller assembly, e, clamping an inner side of the covering roller assembly and turning the connection block and the positioning block, and f, clamping the positioning block and turning and clamping an inner side of the covering roller assembly.

Description

technical field [0001] The invention relates to a welding process, in particular to welding of a connecting block of a cover wheel assembly of a hydraulic torque converter. Background technique [0002] The hydraulic torque converter is a key component used in automatic transmission cars, and its working principle is to use the flow of fluid to smoothly transmit the engine torque to the automatic transmission. The automotive torque converter is mainly composed of pump wheel assembly, guide wheel assembly, turbine assembly, cover wheel assembly and lock-up clutch. It should be noted that the connecting block of the cover wheel assembly is not only an element for connecting the hydraulic torque converter and the gearbox to transmit output torque, but also firmly connected to the gearbox to ensure the permanent and normal operation of the gearbox. The docking of the connecting block of the cover wheel assembly and the gearbox has high requirements on the position and verticali...
