Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] Such as figure 1 , figure 2 As shown, a guide cylinder 2 is arranged on the cylinder body of the first cylinder 1 , the guide cylinder 2 is located above the cylinder body of the first cylinder 1 , and the guide cylinder 2 is fixedly connected with the cylinder body of the first cylinder 1 . The guide cylinder 2 is a steel structure, and the shape of the guide cylinder 2 is square, that is, the outer contour of the cross section of the guide cylinder 2 is square. The piston rod of the first cylinder 1 extends vertically upwards into the guide cylinder 2, and a guide post 3 is arranged above the piston rod of the first cylinder 1. The guide post 3 is located in the guide cylinder 2, and the guide post 3 and the guide cylinder 2 are embedded. The wear-resistant liner 12 is a sliding fit.

[0022] Such as figure 2 , image 3 As shown, a "T" shaped ...

Abstract

The invention discloses a liner tube clamping mechanism for a rear axle assembly welding tool. A piston rod of a first air cylinder is connected with the lower end of a guide pillar. A locating pin is installed at the top end of the guide pillar. A second air cylinder is arranged on a guide cylinder. A piston rod of the second air cylinder is connected with one end of a pressing arm. A pressing head is fixed to the bottom face of the other end of the pressing arm. A big-end-up two-section type step hole is formed in the center of the locating pin. A long countersunk screw is arranged in the step hole in a penetrating manner. A connector is arranged between the guide pillar and the piston rod of the first air cylinder. A boss of the head of the connector is clamped in a T-shaped through groove in the lower end of the guide pillar. The lower end of the connector is in threaded connection with the piston rod of the first air cylinder. A connecting plate is arranged between the guide cylinder and the second air cylinder. The connecting plate is formed by stamping a steel plate and is provided with a first plate body and a second plate body, wherein an obtuse angle is formed between the first plate body and the second plate body. According to the liner tube clamping mechanism, control is convenient, operation is flexible and reliable, accuracy and stability of liner tube locating can be achieved, the welding quality is guaranteed, and the requirement for consistent production can be met.

Description

technical field [0001] The invention belongs to the technical field of tool fixtures, and in particular relates to a liner clamping mechanism of a rear axle assembly welding tool. Background technique [0002] The rear axle assembly of the automobile is composed of a beam, a longitudinal arm, a spring seat, a liner, a parking brake cable bracket, an oil pipe bracket and a shock absorber mounting seat, etc., and the longitudinal arms are welded symmetrically at both ends of the beam. Weld liner, parking brake cable bracket, shock absorber mount and oil pipe bracket in sequence. During welding, it is necessary to position the beam, longitudinal arm, spring seat, liner, etc. in different steps with the help of multiple tooling. The existing liner positioning tool has complex structure, large space occupation, high cost, difficult alignment, and poor positioning stability, which makes it difficult to guarantee the welding quality and fail to meet the requirements of consistent ...
