Problems solved by technology

Although the structure of this method is simple, it is easy to cause the bush to pop out due to uneven force in the process of pressing the bush.
One is that it affects safety; the other is that the test process is unstable; the third is that the test results are unreliable
Fourth, the skill requirements for the experimenters are relatively high

Embodiment

[0023] Example: such as Figure 2-Figure 4 As shown, the swing arm bushing rubber and skeleton pull-off test tool mainly includes a tensile testing machine 1, a bushing outer positioning seat 2 and a pull rod 3, and the tensile testing machine 1 is provided with a fixed bushing outer positioning seat 2 The lower clamping mechanism 1-1 and the upper clamping mechanism 1-2 for fixing the pull rod 3, the outer frame 4 is fixed in the bushing outer positioning seat 2, the pull rod 3 is connected with the inner frame 5, and the upper clamping mechanism 1-2 Moving up drives the pull rod 3 to disengage the inner frame 5 from the outer frame 4 . The detachment process is realized in the outer positioning seat 2 of the bush, so the problem of the pop-up of the bush will not occur.

[0024] An observation hole 2-1 is provided on the outer positioning seat 2 of the bush for close-range observation of the degumming process, with high safety performance.

[0025] The bushing outer positi...

Abstract

The invention relates to the field of automobile part experiment tools, in particular to a swing arm bushing rubber and framework pull-off test tool which comprises a tension testing machine, a bushing inner positioning base, a bushing outer positioning base and a pull rod, wherein the tension testing machine is provided with a lower clamping mechanism for fixing the bushing outer positioning base and an upper clamping mechanism for fixing the pull rod, an outer framework is fixed in the bushing outer positioning base, the pull rod is connected with an inner framework, and the upper clamping mechanism moves upwards to drive the pull rod to separate the inner framework from the outer framework. Due to the fact that the separation process is achieved in the bushing outer positioning base, the problem that the bushing pops up cannot occur.

Description

technical field [0001] The invention relates to the field of experimental tooling for auto parts, in particular to a tooling for pulling off a swing arm bush rubber and a frame. Background technique [0002] The automobile swing arm bush is one of the main components of the automobile chassis, and the manufacturing quality of the swing arm bush directly affects the quality of the whole vehicle. For example, the degumming of the bushing will affect the user's comfort, abnormal noise, and even safety performance. Generally, the front swing arm of a car has two bushes, the front bush and the rear bush. Usually, the rear bushing is a skeleton structure of inner and outer steel parts, and the connection of the inner and outer skeletons of the bushing B is a bushing assembly formed after rubber vulcanization. Because the inner and outer frames of the bushing are connected by rubber, the rubber adhesion rate between the rubber and the metal surface of the frame must meet the requ...
