DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the detection tool for the hub brake seat of the present invention is specifically described below in conjunction with the embodiments and drawings.

[0024] <Example>

[0025] This embodiment provides a wheel hub brake seat detection tool 10, especially for detecting the installation surface of the disc brake seat of the disc brake wheel hub, such as Figure 3 and Figure 4 As shown, the brake seat 30 which can be removed and placed on the wheel hub 20 is used to detect whether the mounting surface 31 of the brake seat 30 meets the installation requirements. The main detection principle is: the mounting surface 31 of the brake seat 30 (i.e., the mounting plane at the screw hole position, such as Figure 3As shown in the figure, it usually has a certain standard tolerance range (preset standard tolerance), such as ±0.15mm. By using the detection tool 10 to determine whether the mounting surface of the brake seat to be detected is within this tolerance range, it can be identified whether the mounting surface of the brake seat meets the installation standard.

[0026] The detection tool 10 includes a main body 11, a mounting portion 12 and a detection portion. The mounting portion 12 and the detection portion are both arranged on the main body 11, and the main body 11 is in the shape of an elongated strip. The mounting portion 12 is located in the middle of the main body 11. The detection portion has at least two detection heads of different heights, which are respectively placed at the two ends of the main body 11, that is, the two detection heads are respectively located on both sides of the mounting portion 12, and are used to cooperate with the mounting surface 31 of the brake seat 30. During detection, the mounting portion 12 can be installed on the brake seat 30 in an inserted manner, and can be rotated relative to the brake seat 30, and the detection head rotates with the main body 11 and the mounting portion 12. Figure 1 As shown, the two detection heads are respectively a first detection head 13 and a second detection head 14. The bottom of the first detection head 13 has a first detection surface 131 for contacting with the surface to be detected (i.e., the mounting surface 31) of the brake seat 30. The bottom of the second detection head 14 has a second detection surface 141. The height of the surface where the first detection surface 131 is located is higher than the height of the surface where the second detection surface 141 is located (e.g., Figure 2 As shown in the figure, when detecting a disc brake seat that meets the standard, the first detection surface 131 sweeps over the mounting surface 31 from above the mounting surface 31, and the height of the plane where the second detection surface 141 is located is lower than the plane where the mounting surface 31 is located, that is, the second detection surface 141 cannot pass over the mounting surface 31. The heights of the first detection surface 131 and the second detection surface 141 correspond to the upper and lower limits of the preset standard tolerance of the mounting surface 31 of the brake seat 30, respectively, that is, the height difference between the first detection surface 131 and the second detection surface 141 is the difference between the positive and negative values ​​of the standard tolerance of the mounting surface 31. For example, when the standard tolerance of the mounting surface 31 of the brake seat 30 is ±0.15mm, the height difference between the first detection surface 131 and the second detection surface 141 is +0.15-(-0.15) = 0.3mm. During detection, by rotating the main body 11 , the detection portion is driven by the main body 11 to sweep across the installation surface 31 from above the installation surface 31 to detect the installation surface 31 .

[0027] In this embodiment, the main body is in the shape of an elongated strip, the mounting portion 12 is located in the middle of the main body 11, the first detection head 13 and the second detection head 14 are respectively arranged at two ends of the main body 11, and the first detection head 13 and the second detection head 14 are equidistant from the mounting portion 12 and are symmetrically arranged on both sides of the mounting portion 12.

[0028] like Figure 2As shown, the mounting portion 12 has an insertion section 121 and a connecting section 122. The insertion section 121 is used to be inserted into the central hole 32 of the brake seat 30. One end of the connecting section 122 is connected to the main body 11, and the other end is connected to the insertion section 121. An abutment surface 123 protruding from the insertion section 121 is formed at one end of the connecting section 122 close to the insertion section 121.

[0029] like Figure 3-Figure 5 As shown, the wheel hub 20 is provided with a mounting shaft 21 for mounting the brake seat 30, and a bearing 22 is mounted in the mounting shaft 21. The middle part of the bearing 22 has a bearing hole 23 coaxially arranged with the center hole 32. The brake seat 30 is provided with a plurality of mounting seats arranged circumferentially, and the surface of the mounting seat is the mounting surface 31. In this embodiment, there are three mounting seats, and the surface of each mounting seat is on the same plane, forming three mounting surfaces 31. A threaded hole for mounting is provided in the middle part of each mounting seat. The three mounting seats are arranged circumferentially on the outside of the brake seat 30, and a gap is formed between two adjacent mounting seats. When performing detection, the insertion section 121 can be inserted into the bearing hole 23, and when the insertion section 121 is inserted into the bearing hole 23, the abutment surface 123 abuts against the end face of the bearing 22; the first detection surface 131 abuts against the mounting surface 31. See. Figure 5 , the height difference between the plane where the first detection surface 131 is located and the plane where the abutting surface 123 is located is equal to the height difference (h) between the plane where the end surface of the bearing 22 is located and the plane where the mounting surface 31 is located. During detection, the insertion section 121 is inserted into the bearing hole 23, and the main body 11 is rotated. The first detection surface 131 can pass over the mounting surface 31, while the second detection surface 141 is lower in height than the first detection surface 131. Therefore, it will be blocked by the side of the mounting surface 31 during the rotation process and cannot pass over the mounting surface 31. The second detection head 14 is limited in the interval formed between two adjacent mounting seats.

[0030] Since the height difference between the first detection head 13 and the second detection head 14 is relatively small, in order to facilitate user judgment, a "through" mark can be marked on the end of the main body 11 close to the first detection head 13 (indicating that the detection head at this end should pass over the installation surface 31 to be detected), and a "stop" mark can be marked on the end of the main body 11 close to the second detection head 14 (indicating that the detection head at this end should be blocked by the installation surface 31).

[0031] In addition, in order to facilitate easier rotation during the detection process, a handle can be provided on the main body 11 in an integrated or separate manner. When provided in a separate manner, the handle is fixed to the main body 11 by screws. When provided in an integrated manner, the handle and the main body 11 can be integrally formed or fixed together by welding.

[0032] The detection steps and judgment method of this embodiment are as follows:

[0033] Step 1: insert the extending section 121 on the mounting portion 12 of the detection tool 10 into the bearing hole 23 of the mounting shaft 21 of the disc brake hub to be detected, and make the abutting surface 123 abut against the end surface of the bearing 22;

[0034] Step 2: Rotate the main body 11 to drive the first detection head 13 and the second detection head 14 to rotate. If the first detection surface 131 on the bottom surface of the first detection head 13 can normally pass over the first mounting surface 31, and the second detection head 14 is blocked by the other mounting surface 31 and cannot continue to rotate, it means that the height of the first mounting surface 31 meets the standard, and the detection of the first mounting surface 31 is completed; if the second detection head 14 can also pass over the other mounting surface 31, it means that the height difference between the two mounting surfaces 31 is greater than the standard tolerance range of the mounting surface, which means that the object under test does not meet the requirements and needs to be marked or screened out as a defective product;

[0035] Step 3: For the above-mentioned workpiece that meets the standards, remove the detection tool 10 from the above-mentioned disc brake hub, adjust a certain angle and insert it again into the bearing hole 23 of the mounting shaft 21 of the disc brake hub to be tested, repeat the above steps 1-2 to inspect the second mounting surface 31 and determine whether it meets the standards; continue to repeat the above step 3 to detect the next mounting surface 31, until all mounting surfaces 31 have been tested, the test is completed, and the detection tool 10 can be removed.

[0036] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
