[0002] The brake pad is the important structure of the brake system, and is also the important component part of the safe running of the traffic tool. The brake pad is generally composed of the steel plate, the heat insulation layer and the friction block, and the steel plate needs to be coated to prevent rust and also needs to be detected in a series of related ways. Especially in the production process of the super thin brake pad, if the brake pad is too thin, the brake effect will be weakened, the brake distance will be affected, and the metal friction sound will be generated in the brake process, which affects the driving feeling. Therefore, the thickness needs to be detected in the production process of the super thin brake pad to ensure that the thickness meets the safety use standard. The traditional brake pad thickness detection mode is to detect the thickness by the micrometer and other measuring tools, and the detection efficiency is low.

[0017] The following will be combined with the drawings Figures 1-6 The specific embodiment of the utility model is further explained in detail.

[0018] In Embodiment 1, the technical solution is as follows: the card holder 1 is integrally formed by plate A 2, plate B 3, and plate C 4. During use, a vertical groove 8 is arranged on the vertical cylinder 5, and a guide rod 9 corresponding to the vertical groove 8 is arranged on the detection rod 6. Due to the restriction of the guide rod 9 and the vertical groove 8, the detection rod 6 can only move vertically along the vertical cylinder 5 and cannot rotate. Two indicator lines 23 are arranged on the display disk 22, which is fixedly connected to the support rod 21. These two indicator lines 23 define the normal thickness range of the brake pad 27. During the detection process, if the thickness of the brake pad 27 is within the normal range, the pointer 20 is located within region A 24. To facilitate the rotation of the pointer 20 with the indicator shaft 18, a through hole 25 is arranged on the display disk 22.

[0019] When using this application, first pull the detection rod 6 upward along the vertical cylinder 5, then place the brake pad 27 to be tested on the A plate 2 of the bracket 1 and release the detection rod 6. Under the action of the spring 15, the detection rod 6 automatically moves downward to abut against the upper end of the brake pad 27. Then observe the pointer 20 of the deviation display device 12. If the pointer 20 is within the normal thickness range (i.e., area A 24), the thickness of the brake pad 27 meets the requirements; if the pointer 20 is to the left of the normal thickness range (i.e., area A 24), the thickness of the brake pad 27 exceeds the normal range; if the pointer 20 is to the right of the normal thickness range (i.e., area A 24), the thickness of the brake pad 27 is below the normal range. The detection speed is fast, and it can intuitively determine whether the thickness of the brake pad 27 meets the standard.

[0020] In Example 2, based on Example 1, under normal conditions (i.e., in non-detection state), the detection head 7 at the lower end of the detection rod 6 contacts the upper end of the C plate 4. At this time, the spring 15 is in its natural state, and the pointer 20 of the deviation display device 12 is located on the right side of area A 24 on the display disk 22.

[0021] When it is necessary to inspect brake pads 27, as shown in the attached diagram of the instruction manual. Figure 1 As shown, first pull the detection rod 6 upwards to prevent the detection head 7 from interfering with the placement of the brake pad 27. A pull rod 26 is provided to facilitate the pulling of the detection rod 6. The pull rod 26 pulls the detection rod 6 and the detection head 7 upwards along the vertical cylinder 5. During this upward movement, the spring 15, which is fixedly connected between the upper baffle 14 and the lower baffle 13, will be compressed. Pull the detection rod 6 upwards until the detection head 7 no longer interferes with the placement of the brake pad 27. Then, place the brake pad 27 as shown. Figure 1The detection rod 6 is placed on the A plate 2 of the card frame 1, and then slowly loosens the detection rod 6, which is automatically extended along the vertical cylinder 5 under the action of the spring 15, and the detection head 7 at the lower end of the detection rod 6 will automatically abut against the upper end of the brake pad 27. At this time, if the pointer 20 is in the normal thickness range (i.e. the A area 24), the thickness of the brake pad 27 meets the requirements; if the pointer 20 is on the left side of the normal thickness range (i.e. the A area 24), the thickness of the brake pad 27 exceeds the normal range; if the pointer 20 is on the right side of the normal thickness range (i.e. the A area 24), the thickness of the brake pad 27 is lower than the normal range.

[0022] The principle is: if the thickness of the brake pad 27 is within the normal range, the pointer 20 is in the A area 24; if the thickness of the brake pad 27 exceeds the normal range, it means that the height of the detection rod 6 moves upward relative to the normal range, the detection rod 6 moves upward, the guide rod 9 moves upward along the vertical groove 8, the guide rod 9 moves upward through the rack 10 and acts on the large gear 17 of the deviation amplification device 11, so that the large gear 17 rotates counterclockwise, the large gear 17 rotates counterclockwise to drive the small gear 19 on the mounting bracket 16 and the indicating shaft 18 to rotate clockwise, and then the pointer 20 on the indicating shaft 18 will also rotate clockwise synchronously, and then the pointer 20 will move to the left side of the A area 24; correspondingly, if the thickness of the brake pad 27 is lower than the normal range, it means that the height of the detection rod 6 moves downward relative to the normal range, the detection rod 6 moves downward, the guide rod 9 moves downward along the vertical groove 8, the guide rod 9 moves downward through the rack 10 and acts on the large gear 17 of the deviation amplification device 11, so that the large gear 17 rotates clockwise, the large gear 17 rotates clockwise to drive the small gear 19 on the mounting bracket 16 and the indicating shaft 18 to rotate counterclockwise, and then the pointer 20 on the indicating shaft 18 will also rotate counterclockwise synchronously, and then the pointer 20 will move to the right side of the A area 24.

[0023] It should be noted that the large gear 17 and the small gear 19 of the present application have a certain large gear ratio (which can be set according to actual use requirements), which satisfies that the large gear 17 rotates one circle and the small gear 19 rotates multiple circles, and then when detecting the thickness of the detection disc, the small thickness difference of the brake pad 27 will also cause the small displacement of the detection rod 6, the small displacement of the detection rod 6 will act on the deviation amplification device 11 through the rack 10, so that the small gear 19 and the indicating shaft 18 will have a larger action change, and then the small thickness difference of the brake pad 27 is amplified, ensuring the accuracy and sensitivity of the thickness detection.
