Embodiment 1

[0041] The embodiment discloses a transmission shaft assembly straightening welding process, the operation of which is basically as attached figure 1 As shown, it specifically includes the following steps:

[0042] Step 1: Prepare several first universal joint yokes, front axle, support, second universal joint yoke, third universal joint yoke, rear axle and fourth universal joint yoke.

[0043] Step 2: Prepare the all-in-one transmission shaft press-fitting and welding machine, including processing table 10, four welding units, four alignment units, limit unit, cover 805, and five clamps for clamping the universal joint fork or support For the clamping unit, a mounting plate 101 is vertically welded on the processing table 10, and the mounting plate 101 is in the shape of a "Π"; the processing table 10 is fixedly provided with a first sliding unit for horizontal sliding of the clamping unit.

[0044] Such as figure 2 As shown, the first slide unit includes a first slide rai...

Abstract

The invention relates to the field of drive shaft processing, and specifically discloses a straightening welding process for a drive shaft assembly, including a plurality of first universal joint yokes, a front axle, a support, a second universal joint yoke, a third universal joint yoke, The preparation steps of the rear axle and the fourth universal joint yoke; the preparation steps of the transmission shaft press-fit welding integrated machine; the press-fit step; the alignment detection step; the welding step. This solution can straighten and weld the transmission shaft assembly without transfer after assembly and press-fitting, and can solve the problem that there is an error in the installation of the transmission shaft assembly, and thus cannot meet the full run-out problem.

Description

technical field [0001] The invention belongs to the field of transmission shaft processing, and in particular relates to a straightening and welding process of a transmission shaft assembly. Background technique [0002] In order to meet the market demand for increased car space, the industry has extended the wheelbase of the car, and the length of the corresponding drive shaft is also lengthened. After the drive shaft is too long, the distance between the drive shaft, the sliding joint and the differential If the angle difference is too large, the torque on the transmission shaft will be difficult to transmit along the axis of the transmission shaft, which will directly affect the dynamic performance of the transmission shaft, so the transmission shaft will be divided into front and rear axles, and between the front and rear axles It is connected by bearing and universal joint fork. [0003] When installing a conventional segmented transmission shaft, first weld the first ...
