Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings.

[0021] see Figure 1 to Figure 7 , the shown clamping device for bushing stiffness test includes a cylindrical body 1 in the shape of a regular octagonal prism, and the cylindrical wall of the cylindrical body 1 is provided with a first radial screw hole 11 connected to the test bench and a number of circumferentially uniform Distributed second radial screw holes 12, the first radial screw holes 11 and the second radial screw holes 12 are alternately arranged on adjacent sides of the regular octagonal prism.

[0022] A radial adjustment bolt 2 is screwed into each second radial screw hole 12 , and the end of the radial adjustment bolt 2 extending into the inner hole of the cylinder body 1 abuts against the outer surface of the locking block 3 . The inner side of the locking block 3 is adapted to the outer wall of the bushing 8 to be tested. Clamping requirements for ...

Abstract

The invention discloses a clamping device for a lining rigidity test, which comprises a cylinder body, a first radial screw hole connected with a test bench and a plurality of second radial screw holes uniformly distributed along the circumferential direction are arranged on the cylinder wall of the cylinder body, and a radial adjusting bolt is screwed into each second radial screw hole. The end portion, extending into the inner hole of the cylinder, of the radial adjusting bolt abuts against the outer side face of the locking block, the inner side face of the locking block is matched with the outer wall of the to-be-tested lining, and by adjusting the screwing-in amount of the radial adjusting bolt in the second radial screw hole, adjustment of the space defined by the inner side face of the locking block is achieved, and the clamping requirements of the to-be-tested linings with different diameters are met. The clamping device can meet the rigidity test clamping requirements of bushings with different diameters, and is good in universality.

Description

technical field [0001] The invention relates to a bushing testing tool, in particular to a clamping device for bushing stiffness testing. Background technique [0002] In the structure of auto parts, especially when it comes to chassis bushing parts, it is necessary to test the performance of the bushing, and the diameter of the bushing in different models and different positions is inconsistent. Generally, bushings of different sizes are used to design and process corresponding clamping tooling, which greatly increases tooling manufacturing costs and management costs. In view of the above problems, it is necessary to design a clamping device for bushing stiffness test with variable diameter. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a clamping device for bushing stiffness testing, which can meet the clamping requirements for bushing stiffness testing with different diameters, and has good versatility. [0004] The clamping devi...
