AI Technical Summary
In the existing technology, when the stabilizer bar bushing is connected to the testing machine, the clamp cannot be directly connected, resulting in a large stiffness of the tested product, which cannot reflect the actual stiffness of the product and affects the test results.
A test fixture for stabilizer bar bushings was designed, comprising an upper clamp, a lower clamp, a stabilizer bar bushing, and a clamp, which are connected by M8 bolts and assembled using the clamp. A protective chamber is provided between the clamp and the clamp to avoid deformation interference and ensure test accuracy.
It enables accurate stiffness testing of stabilizer bar bushings, avoiding the impact of excessive stiffness of the fixture body on test results, and the test results are closer to the actual vehicle installation state.

[0018] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0019] Referring to Figures 1-4 , stabilizer bar bushing test tooling, including upper clamp 1, lower clamp 2, stabilizer bar bushing 3 and clamp 4.
[0020] The first semicircular hole 101 is formed in the lower end of the upper clamp 1, and the second semicircular hole 201 is formed in the upper end of the lower clamp 2. Two recesses 8 are formed in the inner wall of the first semicircular hole 101, and the clamp 4 is located in the first semicircular hole 101 and the two recesses 8. The side wall of the stabilizer bar bushing 3 is attached to the inner side wall of the clamp 4 and the inner side wall of the second semicircular hole 201. The upper clamp 1, the lower clamp 2 and the clamp 4 are connected by two M8 bolts 5. The lower end of the clamp 4 is located below the lower end of the upper clamp 1, so that the clamp 4 can be clamped after being connected between the upper clamp 1 and the lower clamp 2.
[0021] Threaded mounting holes 6 are formed in the upper end and the side walls of the upper clamp 1, which can be connected to the external testing machine through L-shaped iron or screw rods.
[0022] The protection chamber 7 is formed between the inner side wall of the first semicircular hole 101 and the outer side wall of the clamp 4, which avoids interference between the clamp 4 and the upper clamp 1 after deformation under pressure, affecting the test results of the stabilizer bar bushing 3.
[0023] In the test of the stabilizer bar bushing 3, first, the stabilizer bar bushing 3 is placed in the second semicircular hole 201, then the clamp 4 is placed in the first semicircular hole 101 and the two grooves 8, and the connection between the upper clamp 1, the lower clamp 2 and the clamp 4 is achieved through two M8 bolts 5, then the worker can be connected with the external testing machine through the threaded mounting hole 6 and the external screw rod;
[0024] Then start the testing machine, at this time the stiffness of the stabilizer bar bushing 3 can be detected through the clamp 4, and the protective chamber 7 is formed between the inner side wall of the first semicircular hole 101 and the outer side wall of the clamp 4, so as to avoid the interference between the clamp 4 and the upper clamp 1 after the clamp 4 is deformed under pressure, and affect the test result of the stabilizer bar bushing 3, so that the scheme uses the clamp 4 for assembly, and avoids the problem that the main body stiffness of the clamp itself is too large, causing the detection stiffness to be large.
