[0021] In an optional embodiment: the surface of threaded sleeve 2 is provided with threads, the fixed platform 1 is provided with a plurality of threaded holes 10 matched with threaded sleeve 2, the plurality of threaded holes 10 are uniformly distributed on the fixed platform 1, the threaded sleeve 2 can be threadedly connected in the threaded hole 10, the threaded sleeve 2 can be fixedly connected in the threaded hole 10 at different positions on the fixed platform 1, so that the position of threaded sleeve 2 on the fixed platform 1 can be adjusted, so that the threaded sleeve 2 connected on the fixed platform 1 is aligned with the brake caliper mounting hole 3 on the brake caliper body 4, the threaded sleeve 2 is convenient to pass through the brake caliper mounting hole 3 for limiting.

[0022] This detachable connection mode not only facilitates installation and adjustment, but also facilitates replacement or repair of damaged threaded sleeves during long-term use.

[0023] In an optional embodiment: the opposite ends of the two nut limit sleeves 28 are connected with rubber gaskets 281, the friction force of the contact surface with the brake caliper body 4 can be increased through the rubber gaskets 281, and the rubber gaskets 281 can also abut against the side surface of the brake caliper body 4 tightly, thereby improving the limiting effect.

[0024] When the nut limiting sleeve is moved towards each other, the rubber pad first contacts the two sides of the brake caliper body. The rubber pad has the effect of increasing the friction force of the contact surface with the brake caliper body, so that the nut limiting sleeve can tightly abut against the brake caliper body to prevent displacement in the left-right direction (X direction); on the other hand, the rubber pad is relatively soft, which can avoid scratching or damaging the surface of the brake caliper body during clamping.

[0025] In an optional embodiment: the upper and lower sides of the threaded sleeve 2 are provided with sliding openings 20 matched with the side limiting blocks 21, the side limiting blocks 21 are slidingly connected in the sliding openings 20, and the elastic member includes a connecting block 23 and a spring 22, the connecting block 23 is fixedly connected inside the threaded sleeve 2, and one end of the side limiting block 21 extends to the inside of the threaded sleeve 2 and is connected with the spring 22.

[0026] In an optional embodiment: one end of the side limiting block 21 located inside the threaded sleeve 2 is connected with a rope 25, the other end of the rope 25 extends to the outside of the threaded sleeve 2 and is connected with a pull handle 27, and the side limiting block 21 connected with the rope 25 can be pulled through the pull handle 27 to pull the side limiting block 21 into the inside of the threaded sleeve 2.

[0027] In an optional embodiment: a guide wheel 24 is installed inside the threaded sleeve 2, a guide sleeve 26 is connected to one end of the threaded sleeve 2 close to the pull handle 27, and one end of the rope 25 passes through the guide wheel 24 and the guide sleeve 26 in sequence, and the guide wheel 24 and the guide sleeve 26 can stably guide the rope 25, thereby effectively driving the side limiting block 21 to move up and down on the threaded sleeve 2.

[0028] Working principle: when the brake caliper body 4 is fixed to the fixed table 1, first, the threaded sleeve 2 is connected to the corresponding position of the fixed table 1 through the threaded hole 10, one of the nut limiting sleeves 28 is threadedly connected to the threaded sleeve 2, the side limiting block 21 is made to enter the sliding opening 20 by pulling the pull handle 27, then the threaded sleeve 2 is passed through the brake caliper mounting hole 3 on the brake caliper body 4, so that one side of the brake caliper body 4 abuts against the nut limiting sleeve 28, then the other nut limiting sleeve 28 is rotated, so that the two nut limiting sleeves 28 can abut against the two sides of the brake caliper body 4, then the pull handle 27 is loosened, and the side limiting block 21 is reset by the elastic force of the spring 22, so that the side limiting block 21 abuts against the upper and lower side walls of the brake caliper mounting hole 3 to limit the brake caliper body 4 upward and downward, thereby realizing stable limiting of the brake caliper, and the brake caliper body is stably fixed on the fixed table in multiple directions, so that subsequent high-pressure testing, wear resistance testing and other detection operations can be performed.

[0029] More specifically, in the installation preparation stage, first, according to the position and spacing of the brake caliper mounting hole on the brake caliper body to be detected, select the threaded hole at the appropriate position on the fixed table, install the threaded sleeve on the fixed table through threaded connection, ensure that the position of the threaded sleeve can correspond to the brake caliper mounting hole, and facilitate subsequent operation. In the brake caliper installation process, select a nut limiting sleeve and threadedly connect it to the threaded sleeve, but do not tighten it, so that it has a certain movement space on the threaded sleeve. Pull the pull handle, and the pull handle, through the coordinated action of the rope body, guide wheel and guide sleeve, pulls the side limiting block into the threaded sleeve along the sliding port, at this time the spring is stretched. Pass the threaded sleeve through the brake caliper mounting hole on the brake caliper body until the side of the brake caliper body contacts the installed nut limiting sleeve, at this time the brake caliper body has a certain movement space on the threaded sleeve. In the brake caliper clamping and limiting stage, rotate the other nut limiting sleeve so that it moves along the threaded sleeve towards the installed nut limiting sleeve, and as the two nut limiting sleeves move towards each other, the rubber gasket gradually tightly abuts against both sides of the brake caliper body, clamping and limiting the brake caliper body in the left-right direction (X direction). When the two nut limiting sleeves clamp the brake caliper body to the appropriate degree, loosen the pull handle. At this time, the stretched spring moves the side limiting block outward along the sliding port under the action of its own elastic force until the side limiting block abuts against the upper and lower side walls of the brake caliper mounting hole, limiting the brake caliper body in the up-down direction (Y direction). At this point, the brake caliper body is stably fixed on the fixed table in multiple directions, and subsequent detection operations such as high-pressure testing and wear testing can be performed. When the brake caliper detection is completed, pull the pull handle again to make the side limiting block enter the threaded sleeve, then rotate the nut limiting sleeve in the opposite direction to loosen the clamping of the brake caliper body, and finally remove the threaded sleeve from the fixed table to complete the installation and disassembly operation in the entire detection process.

[0030] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
