Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 In this embodiment of the present invention, a brake disc surface inspection device includes a base 1. A vertically arranged vertical rod 2 is welded to the center of the top of the base 1. A fixing ring 3 is fixedly installed on the outer wall of the vertical rod 2. A sliding ring 4 is slidably installed on the outer wall of the vertical rod 2 above the fixing ring 3. A guide ring 5 is integrally formed on the outer periphery of both the fixing ring 3 and the sliding ring 4. A sliding rod 6 is axially slidably installed on the inner periphery of the guide ring 5. A connecting plate 7 is fixedly installed at the front end of the sliding rod 6. A connecting rod 8 is fixedly installed at one end of the connecting plate 7. A mounting seat 9 is integrally formed at the front end of the connecting rod 8. An upper dial indicator 10 is fixedly installed on the inner periphery of the upper mounting seat 9, and a lower dial indicator 11 is fixedly installed on the inner periphery of the lower mounting seat 9. The upper and lower connecting rods 8 are connected by an adjustment mechanism.

[0022] In this embodiment: First, the brake disc to be tested is installed on a horizontal fixed clamping platform (e.g., a clamping device for internal clamping of the center hole of the brake disc is installed on the clamping platform). At this time, the bottom end of the brake disc is in contact with the top of the long rod of the lower sensing rod 13. Then, the position of the upper dial indicator 10 is adjusted by the adjustment mechanism until the bottom end of the upper sensing rod 12 of the upper dial indicator 10 is in contact with the top surface of the brake disc. Then, the flatness test can be performed. During the test, the upper sliding rod 6 can be pulled to slide. The upper sliding rod 6 drives the lower sliding rod 6 to slide synchronously through the adjustment mechanism, so as to realize the synchronous movement of the upper dial indicator 10 and the lower dial indicator 11, thereby performing flatness test on different positions on both sides of the brake disc.

[0023] Please refer to this carefully. Figure 1 and Figure 2 The adjustment mechanism includes a limiting ring 15 integrally formed on the tail end of the upper sliding rod 6 and a mounting ring 14 integrally formed on the tail end of the lower sliding rod 6. A guide rod 16 that is slidably connected to the limiting ring 15 is fixedly installed on the top of the mounting ring 14. The adjustment mechanism also includes a screw 17 fixedly installed on the top of the outer plate of the fixing ring 3. The screw 17 is threadedly connected to the outer plate of the sliding ring 4. The upper outer periphery of the screw 17 is rotatably connected to the plate at the top of the vertical rod 2. A handle 18 is installed on the top of the screw 17.

[0024] In this embodiment: when adjusting the height of the dial indicator 10, the handle 18 is rotated, which drives the screw 17 to rotate. The rotating screw 17 drives the sliding ring 4 to move up and down. At this time, the sliding ring 4 drives the dial indicator 10 to adjust its height through the upper sliding rod 6, connecting plate 7, and connecting rod 8 until the bottom end of the upper sensing rod 12 of the dial indicator 10 contacts the upper surface of the brake disc. At the same time, the upper sliding rod 6 drives the limiting ring 15 to move up and down along the outer wall of the guide rod 16.

[0025] Please refer to this carefully. Figure 3 and Figure 4 Both the upper dial gauge 10 and the lower dial gauge 11 have speed-increasing rotating mechanisms installed inside their annular portions. The speed-increasing rotating mechanisms include rotating gears 21 that are rotatably mounted on the inner walls of the upper dial gauge 10 and the lower dial gauge 11. A connecting gear 22 is coaxially connected to the front end of the rotating gear 21. A first speed-increasing gear 23 meshes with the outer side of the connecting gear 22. A transmission gear 24 is coaxially connected to the front end of the first speed-increasing gear 23. A second speed-increasing gear 25 meshes with the outer periphery of the transmission gear 24. A pointer 26 is coaxially connected to the front end of the second speed-increasing gear 25.

[0026] In this embodiment: During the detection process, the upper and lower surfaces of the rotating brake disc continuously contact the ends of the upper sensing rod 12 and the lower sensing rod 13. If the surface of the brake disc is uneven, the upper sensing rod 12 and the lower sensing rod 13 will move in the vertical direction. At this time, driven by the first rack 20 and the second rack 27, the rotating gear 21 rotates, which in turn drives the first speed-increasing gear 23 to rotate. The angular velocity of the first speed-increasing gear 23 is greater than that of the rotating gear 21. The first speed-increasing gear 23 drives the transmission gear 24 to rotate at the same angular velocity. The transmission gear 24 then drives the second speed-increasing gear 25 to rotate. The angular velocity of the second speed-increasing gear 25 is greater than that of the transmission gear 24. Through acceleration from both sides, the rotation angle is expanded. Therefore, the second speed-increasing gear 25 can drive the pointer 26 to rotate at a larger angle, so that the microscopic unevenness can be displayed as an identifiable error reading.

[0027] Please refer to this carefully. Figure 3 and Figure 4 The upper sensing rod 12 is slidably connected to the inner wall of the hollow rod of the upper micrometer 10, and the lower sensing rod 13 is slidably connected to the inner wall of the hollow rod of the lower micrometer 11. The vertical cross section of the lower sensing rod 13 is a "C"-shaped structure with the opening facing upwards. The inner wall of the hollow rod of the upper micrometer 10 is connected to the inner wall of the annular part of the upper micrometer 10, and the inner wall of the hollow rod of the lower micrometer 11 is connected to the inner wall of the annular part of the lower micrometer 11. A crossbar 19 is fixedly installed at one end of the upper sensing rod 12 and the lower sensing rod 13 located inside the annular part. A first rack 20 is fixedly installed on the top of one crossbar 19. The first rack 20 is meshed with the outer circumference of the rotating gear 21. A second rack 27 is fixedly installed on the top of the other crossbar 19. The second rack 27 is meshed with the outer circumference of the rotating gear 21. The first rack 20 and the second rack 27 are symmetrically distributed.

[0028] In this embodiment: when the upper sensing rod 12 is displaced, the upper sensing rod 12 drives the first rack 20 to move up and down through the crossbar 19. When the lower sensing rod 13 is displaced, the lower sensing rod 13 drives the second rack 27 to move up and down through another crossbar 19. Since the first rack 20 and the second rack 27 are symmetrically distributed, when the upper sensing rod 12 and the lower sensing rod 13 encounter the same protrusion or depression, the two pointers 26 will rotate in the same direction, which is convenient for observation and recording.

[0029] Please refer to this carefully. Figure 5 A torsion spring 28 is fixedly connected between the back end of the two rotating gears 21 and one end of the inner wall of the ring of the upper micrometer 10 and the lower micrometer 11.

[0030] In this embodiment: when the rotating gear 21 rotates, the end of the torsion spring 28 that is fixed to the rotating gear 21 is twisted, while the other end of the torsion spring 28 remains stationary. Therefore, the torsion spring 28 is deformed. At this time, the torsion spring 28 has a restoring force to assist the rotating gear 21 in restoring. The restoring rotating gear 21 then drives the upper sensing rod 12 and the lower sensing rod 13 to restoring.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
