Description

Technical Field

[0001] The utility model relates to the technical field of bushing press-fitting tooling, in particular to a press-fit bushing direction positioning mechanism for chassis structural parts. Background Art

[0002] Automobile chassis structural parts often require soft connections of different stiffness to ensure comfort and handling stability. The soft connection method is usually to press-fit a rubber bushing. In order to ensure stiffness in different directions and prevent sound from extreme collisions, the rubber bushing is usually made with different structures in the two radial directions and has a certain buffer rubber layer at both axial ends. When pressing the structural parts, the rubber bushing is usually operated with the bushing axial direction positioning mechanism fixed. Due to the fixing mechanism, the cross-section rubber on the bushing is easy to be damaged when assembling the bushing. The operator has to manually adjust the bushing direction to ensure the radial stiffness requirements every time the product is pressed. Otherwise, the bushing direction is easy to deviate. Therefore, it is necessary to make a retractable bushing direction positioning pin to fix the bushing, reduce manufacturing costs and avoid damage to the bushing end face rubber and radial deviation. Utility Model Content

[0003] The purpose of the utility model is to remedy the defects of the prior art and provide a direction positioning mechanism for a press-fitted bushing for chassis structural parts. The operation is simple. When operating, the worker only needs to put the bushing on the corresponding fixture positioning pin first, then put the part on the tooling, and start the control switch of the press-fitting machine equipment for press-fitting.

[0004] The utility model is realized by the following technical solutions:

[0005] A press-fit bushing direction positioning mechanism for a chassis structural member comprises a bushing direction positioning mechanism body, a bushing axial direction positioning pin is provided at the center of the right end face of the bushing direction positioning mechanism body, an axial positioning pin mounting hole is opened at the edge position of the right end face, and a bushing radial direction spring positioning pin is installed in the positioning pin mounting hole.

[0006] The outer wall of the bushing direction positioning mechanism body is stepped, and the positioning pin installation hole is located at the step of the bushing direction positioning mechanism body.

[0007] The inner wall at the left end of the locating pin mounting hole is provided with an internal thread, and the bushing radial direction spring locating pin includes a bolt cover, a bushing radial direction locating pin telescopic spring and a bushing radial direction locating pin. The bolt cover is threadedly connected to the left end of the locating pin mounting hole, the left end of the bushing radial direction locating pin telescopic spring is fixedly connected to the bolt cover, and the right end is fixedly connected to the left end of the bushing radial direction locating pin, and the right end of the bushing radial direction locating pin extends out of the locating pin mounting hole.
