[0002] The brake chamber test clamping mechanism is an important part of the brake chamber test system used to fix and clamp the brake chamber for testing. Existing brake chambers are subject to load during positioning and tightening during testing, resulting in poor stability during the test process. Specifically, they have the following disadvantages: uneven clamping force. If the clamping device is not designed properly or adjusted properly, the brake chamber may be subjected to uneven force during the clamping process, thus affecting the accuracy of the test results; poor adaptability. For brake chambers of different specifications and models, different clamping devices may need to be replaced or the clamping mechanism adjusted, increasing the complexity and cost of the test; wear and damage. During long-term use, the clamping device and positioning mechanism may wear or be damaged, affecting the stability and reliability of the test; low degree of automation. Some traditional clamping mechanisms may rely on manual operation for clamping and positioning, reducing test efficiency and increasing the possibility of human error; high maintenance cost.

[0019] In the specific operation process, the swing arm cylinder 6 drives the rotating claw 7 to rotate, and the fixed claw 8 is aligned, so that the plug 12 passes through the round hole at the tail of the connecting fork of the brake air chamber, and then is fastened and locked through the socket 13.

[0020] According to another embodiment of the present invention, the bottom positioning assembly 3 further includes a groove 14 and a clamping block 15; a plurality of groups of clamping blocks 15 are provided around the groove 14, and the clamping blocks 15 are distributed in a circumferential manner.

[0021] According to another embodiment of the present invention, the groove 14 is a hemispherical structure with a through hole 16 in the middle and positioning rings 17 on the four walls.

[0022] Specifically, the through hole 16 is used to place the air inlet on the top of the brake air chamber, and the positioning ring 17 and the clamping block 15 outside the groove 14 position the upper cover, making it convenient for the middle clamping ring assembly 2 and the top clamping block assembly 1 to clamp the brake air chamber.

[0023] According to another embodiment of the present invention, the middle snap ring assembly 2 further includes a left snap ring 18 and a right snap ring 19 that are symmetrically arranged; the left snap ring 18 and the right snap ring 19 are respectively connected to the cylinder output shaft, and are fixed on a group of manual positioning fine-tuning slide assemblies 20 through the cylinder seat, and the manual positioning fine-tuning slide assembly 20 is fixed on the back plate 5.

[0024] The specific operation process is to make the left snap ring 18 and the right snap ring 19 move relative to each other through the cylinder output shaft, and then clamp the middle of the brake air chamber.
