Description

Technical Field

[0001] This invention relates to the field of brake disc clamping structures, and more specifically to a clamping mechanism for testing brake discs in new energy vehicles. Background Technology

[0002] Brake discs are a crucial component of a vehicle's braking system, and their performance directly impacts driving safety. To ensure the performance and safety of brake discs, regular inspection and maintenance are necessary.

[0003] Existing clamping mechanisms for holding brake discs only provide simple clamping and fixing. When inspectors perform various tests on brake discs, especially those requiring precise horizontal and vertical alignment, they must first fix the brake disc, then use a level or vertical gauge to check and adjust its level or verticality before proceeding with the test. This clamping and adjustment process is cumbersome and significantly reduces testing efficiency.

[0004] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a clamping mechanism for testing brake discs in new energy vehicles, which solves the problem of the cumbersome process of adjusting the horizontal and vertical orientation of brake discs in existing technologies.

[0006] The technical solution of this invention is as follows: A clamping mechanism for testing brake discs in new energy vehicles, the brake disc for clamping includes a disc body, on which a mounting boss is provided. The mounting boss has a main mounting hole in the center, and secondary mounting holes are provided around the main mounting hole.

[0007] The distinguishing feature of this application compared to existing technologies is that the clamping mechanism includes a first clamp, a second clamp, a balancing component, and a counterweight. The balancing component and the counterweight have the same shape, and the weight of the balancing component is less than the weight of the counterweight. Both the first and second clamps are provided with connecting shafts for connecting external testing equipment. During clamping, the first clamp is mounted on the side of the brake disc without the mounting boss, and the second clamp is mounted on the side of the brake disc with the mounting boss. A first fixing component is mounted on the first clamp, and a second fixing component is mounted on the second clamp; the first and second fixing components cooperate to fix the brake disc.

[0008] The first fixture is equipped with a level sensor on its end face. When performing a test that requires a certain level of brake disc levelness, the tester can determine whether the brake disc is level by using the level sensor, without the need for other measuring tools.

[0009] The first clamp is equipped with a vertical sensor on its side, and a first slot is provided on the first clamp for inserting a balancing component or counterweight. The center of the vertical sensor, the center of the brake disc, and the center of the first slot are collinear. When performing a test that requires a certain degree of verticality of the brake disc, the tester can determine whether the brake disc is in a vertical position simply by using the vertical sensor, without the need for other measuring instruments.

[0010] As a preferred embodiment of the clamping mechanism for testing new energy vehicle brake discs described in this application, specifically, both the horizontal sensor and the vertical sensor include a housing, with a liquid chamber in the middle of the housing. The liquid chamber contains a balancing fluid and a stop block, and the stop block is movable within the XY plane of the liquid chamber. During testing, the brake disc being in a horizontal or vertical state is indicated by the stop block being located at the exact center of the XY plane.

[0011] In a preferred embodiment of the clamping mechanism for testing new energy vehicle brake discs described in this application, specifically, sensors are mounted on both sides of the housing along the Z-axis of the liquid cavity, and the sensors are positioned opposite each other and directly facing the center of the XY plane of the liquid cavity. Data connectors are provided on the horizontal and vertical sensors. This allows the testing personnel to determine the placement status of the brake disc through an electronic device connected to the data connectors, eliminating the need for manual visual inspection.

[0012] As a preferred embodiment of the clamping mechanism for testing new energy brake discs described in this application, specifically, a fixed shaft is provided on the first fixing member, and a fixed sleeve is provided on the second fixing member. The fixed shaft and the fixed sleeve extend into the sub-assembly hole and cooperate with each other to achieve fixed clamping of the brake disc and prevent the brake disc from deflecting relative to the clamping mechanism.

[0013] As a preferred embodiment of the clamping mechanism for testing new energy vehicle brake discs described in this application, specifically, both the first clamp and the second clamp include a body, and the body is provided with an assembly groove for assembling the first fixing member or the second fixing member. Both the first fixing member and the second fixing member are provided with a limiting shaft, and the assembly groove is provided with a limiting groove for assembling with the limiting shaft. The first fixing member and the second fixing member can be fixed by cooperating with the limiting groove and the auxiliary assembly hole, eliminating the need for threaded connection assembly and simplifying installation.

[0014] In a preferred embodiment of the clamping mechanism for testing new energy vehicle brake discs described in this application, specifically, the first clamp is provided with a first shaft post, and the first slot passes through the first shaft post. The second clamp is provided with a second shaft post, and the second shaft post is provided with a second slot corresponding to the first slot for a balancing component or counterweight to extend into for assembly. The first shaft post and the second shaft post extend into the main assembly hole and cooperate with each other, resulting in a more uniform weight distribution between the first clamp and the second clamp.

[0015] As a preferred embodiment of the clamping mechanism for testing new energy brake discs described in this application, specifically, when the balancer is inserted into the first slot and the second slot, the weight distribution of the first clamp and the second clamp is uniform, so as to avoid the brake disc state from deviating due to uneven weight distribution.

[0016] As a preferred embodiment of the clamping mechanism for testing new energy brake discs described in this application, specifically, the balancer or counterweight includes a shaft, the end of the shaft is provided with a limiting plate, and the first clamp is provided with a limiting groove at the slot of the first slot that cooperates with the limiting plate, so as to prevent the balancer or counterweight from loosening when testing that requires the brake disc to rotate at a high height.

[0017] As a preferred embodiment of the clamping mechanism for testing new energy brake discs described in this application, specifically, the limiting plate is provided with a handle to facilitate the testing personnel to remove the balancing component or counterweight.

[0018] Compared with the prior art, this application has the following advantages: It proposes a clamping mechanism with the function of detecting the horizontal or vertical placement of the brake disc, so that the inspector can directly adjust the brake disc horizontally or vertically when performing different tests without the need for other measuring tools, which greatly improves the testing efficiency.

Furthermore, terms such as first, second, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown.

[0032] Reference Figures 1 to 9 In this application, the brake disc 10 for clamping includes at least a disc body 11, on which a mounting boss 12 is provided. The mounting boss 12 has a main mounting hole 13 in the middle, and a secondary mounting hole 14 is provided around the main mounting hole 13.

[0033] To facilitate the testing of this type of brake disc 10, this application proposes a clamping mechanism for testing new energy vehicle brake discs. The clamping mechanism includes a first clamp 20, a second clamp 26, a balancer 50, and a counterweight 51. The balancer 50 and the counterweight 51 have the same shape, and the weight of the balancer 50 is less than the weight of the counterweight 51. Both the first clamp 20 and the second clamp 26 are provided with a connecting shaft 34, which is used to connect external testing equipment. During clamping, the first clamp 20 is mounted on the side of the brake disc 10 without the mounting boss 12, and the second clamp 26 is mounted on the side of the brake disc 10 with the mounting boss 12. A first fixing member 22 is mounted on the first clamp 20, and a second fixing member 28 is mounted on the second clamp 26. The first fixing member 22 and the second fixing member 28 cooperate to fix the brake disc 10.

[0034] The end face of the first fixture 20 is equipped with a level sensor 40. When performing a test that requires a certain level of levelness of the brake disc 10, the tester can determine whether the brake disc 10 is in a level state by using the level sensor 40, without the need for other measuring tools.

[0035] A vertical sensor 41 is mounted on the side of the first clamp 20, and a first slot 21 is provided on the first clamp 20 for inserting a balancing component 50 or a counterweight 51. The center of the vertical sensor 41, the center of the brake disc 10, and the center of the first slot 21 are collinear. When performing a test that requires a certain degree of verticality of the brake disc 10, before adjusting the verticality of the brake disc 10, the tester needs to insert the counterweight 51 into the first slot 21 so that the overall center of gravity of the clamping mechanism is located downwards, ensuring that the vertical sensor 41 is in a horizontal state. The vertical sensor 41 can be used to determine whether the brake disc 10 is in a vertical state without the need for other measuring instruments.

[0036] It should be noted that, in the application of the clamping mechanism described in this application, before testing, the testing personnel need to insert the balancer 50 into the second slot 27 to ensure that the overall weight distribution is uniform before testing can be carried out.

[0037] In this application, both the horizontal sensor 40 and the vertical sensor 41 include a housing 42. A liquid chamber is disposed in the center of the housing 42, containing a balancing fluid 43 and a stop 44. The stop 44 is movable within the XY plane of the liquid chamber. During detection, the stop 44 being located at the exact center of the XY plane indicates that the brake disc 10 is in a horizontal or vertical state.

[0038] Specifically, the housing 42 is equipped with sensors 45 on both sides of the liquid cavity along the Z-axis, and the sensors 45 are positioned opposite each other and directly facing the center of the XY plane of the liquid cavity. Data connectors 46 are provided on the horizontal sensor 40 and the vertical sensor 41. This allows the inspector to determine the placement status of the brake disc 10 through an electronic device connected to the data connector 46, eliminating the need for manual visual inspection.

[0039] In this application, both the first clamp 20 and the second clamp 26 include a body, on which an assembly groove 31 is provided for assembling the first fixing member 22 or the second fixing member 28. Both the first fixing member 22 and the second fixing member 28 are provided with a limiting shaft 32, and the assembly groove 31 is provided with a limiting groove 33 for assembling with the limiting shaft 32. The first fixing member 22 and the second fixing member 28 can be fixed by cooperating with the limiting groove 33 and the auxiliary assembly hole 14, without the need for threaded connection assembly, making installation simple. The first fixing member 22 is provided with a fixing shaft 23, and the second fixing member 28 is provided with a fixing sleeve 29. The fixing shaft 23 and the fixing sleeve 29 extend into the auxiliary assembly hole 14 and cooperate with each other to achieve fixed clamping of the brake disc 10, preventing the brake disc 10 from deflecting relative to the clamping mechanism.

[0040] To ensure detection accuracy, the first clamp 20 is provided with a first post 24, and the first slot 21 passes through the first post 24. The second clamp 26 is provided with a second post 30, and the second post 30 is provided with a second slot 27 corresponding to the first slot 21, into which the balancing component 50 or the counterweight 51 extends for assembly. The first post 24 and the second post 30 extend into the main assembly hole 13 and cooperate with each other, resulting in a more uniform weight distribution between the first clamp 20 and the second clamp 26. When the balancing component 50 is inserted into the first slot 21 and the second slot 27, the weight distribution of the first clamp 20 and the second clamp 26 is uniform, avoiding deviations in the state of the brake disc 10 during clamping due to uneven weight distribution.

[0041] In this application, the balancer 50 or counterweight 51 includes a shaft 52, and a limiting plate 53 is provided at the end of the shaft 52. The first clamp 20 is provided with a limiting groove 25 at the opening of the first slot 21, which cooperates with the limiting plate 53, to prevent the balancer 50 or counterweight 51 from becoming loose when performing tests that require the brake disc 10 to rotate at a high degree. The limiting plate 53 is provided with a handle 54 to facilitate the removal of the balancer 50 or counterweight 51 by the testing personnel.

[0042] Preferably, the limiting shaft 32 and the limiting groove 33, the fixed shaft 23 and the fixed sleeve 29, and the limiting plate 53 and the limiting groove 25 can be assembled by adsorption structure to ensure the stability of the connection while ensuring the simple installation of the clamping mechanism.

[0043] Compared with the prior art, this application has the following advantages: It proposes a clamping mechanism with the function of detecting the horizontal or vertical placement of the brake disc 10, so that the inspector can directly adjust the brake disc 10 horizontally or vertically when performing different tests, without the need for other measuring tools, which greatly improves the testing efficiency.

[0044] The scope of protection of this invention includes, but is not limited to, the above embodiments. The scope of protection of this invention is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
