Description

Technical Field

[0001] This utility model belongs to the field of brake pad inspection technology, and in particular relates to an inspection device for automotive brake pads. Background Technology

[0002] With the rapid development of the automotive industry, brake pads, as a key safety component of the vehicle braking system, have a performance that is directly related to driving safety. However, in actual production and use, brake pads often suffer from problems such as decreased friction coefficient, severe heat fade, and pad detachment due to unstable material formulation, manufacturing process deviations, or long-term wear. These defects not only affect braking performance but may also lead to serious traffic accidents.

[0003] According to a public disclosure of an automotive brake pad assembly, brake shoe, and brake (Publication No.: CN207470657U), it includes an upper pad for first contacting the brake drum and a lower pad for later contacting the brake drum. The thickness of the upper pad is greater than the thickness of the lower pad. In use, since the wear degree of the upper pad that first contacts the brake drum is greater than the wear degree of the lower pad that later contacts the brake drum, the thickness of the upper pad in the automotive brake pad assembly provided in this application is greater than the thickness of the lower pad.

[0004] In the aforementioned application, the cooperation between components such as the brake drum and the lower liner makes it difficult to solve the problem of flexibly adjusting the distance between the two fixing plates through the cooperation of the sliding groove and the multiple slots. After the limiting rod is inserted into the slot, the position of the fixing plate can be locked, which can effectively prevent the liner from shifting or shaking during the testing process. However, this makes it difficult to stably clamp brake liners of different thicknesses, difficult to lock the position of the fixing plate, difficult to effectively prevent the liner from shifting or shaking during the testing process, and difficult to ensure the accuracy of the measurement data. This issue needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide an inspection device for automotive brake pads. By cooperating with the fixed plate, limiting rod and other components inside the adjustable limit inspection component, it solves the problem that existing methods cannot solve the problem of flexibly adjusting the distance between the two fixed plates through the cooperation of the sliding groove and the multiple slots. After the limiting rod is inserted into the slot, the position of the fixed plate can be locked, which can effectively prevent the pad from shifting or shaking during the inspection process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an inspection device for automotive brake pads, comprising a base, a support rod fixedly connected to the top of the base, a pad being disposed on the top of the base, a bracket being disposed on the side of the support rod, a dial indicator being disposed on the top of the bracket, a measuring probe being disposed on the bottom of the dial indicator, an adjustable limit inspection component being disposed on the top of the base, the adjustable limit inspection component comprising a slide groove being formed on the top of the base, a fixing plate being slidably connected to the inner wall of the slide groove, a limiting rod being rotatably connected to the side of the fixing plate, and a slot being formed on the top of the base.

[0007] Furthermore, the slot is located on the displacement trajectory of the limiting rod. There are two fixing plates, which are symmetrical about each other along the vertical central axis of the liner. The liner to be tested is placed on the top of the base, between the two fixing plates. The two fixing plates slide on the inner wall of the slide groove. When a thinner liner needs to be fixed, the two fixing plates are moved towards the middle along the slide groove at the same time to reduce the distance between the two fixing plates until they fit the liner to be tested. Then the movement stops. After adjusting the position, the limiting rod is rotated along the side of the fixing plate towards the side of the slot. The limiting rod is inserted into the slot to restrict the movement of the fixing plate. The adjusted position of the fixing plate is fixed to keep the liner clamped and standing on the top of the base, thus improving the stability of the test.

[0008] Furthermore, several slots are provided and arranged linearly on the top of the base. The presence of multiple slots facilitates the movement of the mounting plate to any position on the base, allowing the mounting plate to be moved to multiple positions and locked in place, thus improving adaptability.

[0009] Furthermore, several limiting rods are provided, arranged in pairs and symmetrically along the vertical central axis of the base. The measuring probe is located on the top of the liner. The limiting rods ensure the position of the fixing plate and are key to ensuring the limiting of the liner. The presence of several rods improves the stability of the limiting.

[0010] Furthermore, the side of the fixing plate is provided with a replaceable anti-slip component, which includes a circular groove. The circular groove is opened on the side of the fixing plate, and a pin is provided on the inner wall of the circular groove. A rubber pad is fixedly connected to the end of the pin away from the circular groove. A rectangular groove is opened on the side of the rubber pad. The circular groove is opened on the side of the fixing plate that will contact the liner, so that the pin that drives the rubber pad can be inserted into the groove accordingly. The rubber pad is inserted into the circular groove along with the pin. The rubber pad is installed on the side of the fixing plate. The rubber pad increases the friction between the rubber pad and the liner, so that the liner is prevented from sliding when the fixing plate clamps the liner.

[0011] Furthermore, the circular grooves are located on the displacement trajectory of the pin rod. Several circular grooves are provided, and two rubber pads are provided, which are symmetrical to each other along the vertical central axis of the liner. Rubber pads are provided on the sides of both fixing plates, so that the friction can be increased when the two fixing plates clamp the liner, further reducing slippage. The design of the circular grooves and the pin rod allows the rubber pads to be directly pulled out and replaced when they wear out after long-term use, without having to replace the entire fixing plate, thus improving the convenience of replacement.

[0012] Furthermore, several rectangular grooves are provided and arranged linearly on the side of the rubber pad. These rectangular grooves are serrated and designed to provide a biting force when in contact with the liner, thereby reducing the risk of slippage.

[0013] This utility model has the following beneficial effects: This utility model achieves flexible adjustment of the distance between two fixed plates through the cooperation of components such as the fixed plate and the limiting rod inside the adjustable limit inspection component. It can stably clamp brake pads of different thicknesses by using the cooperation of the sliding groove and the multiple slots, which greatly improves the versatility of the device. After the limiting rod is inserted into the slot, it can lock the position of the fixed plate, which can effectively prevent the pad from shifting or shaking during the inspection process and ensure the accuracy of the measurement data.

[0014] This invention utilizes the interplay between components such as the circular groove and the pin rod within the anti-slip assembly. This combination of the high-friction rubber pad material and the serrated rectangular groove provides stronger gripping force, effectively preventing the liner from slipping during testing and ensuring testing stability and data accuracy. The plug-in design of the pin rod and the circular groove allows the rubber pad to be directly plugged in and replaced without disassembling or replacing the entire fixing plate, significantly reducing maintenance time.

[0017] An inspection device for automotive brake pads includes a base 1, a support rod 2 fixedly connected to the top of the base 1, a pad 3 disposed on the top of the base 1, a bracket 4 disposed on the side of the support rod 2, a dial indicator 5 disposed on the top of the bracket 4, a measuring probe 6 disposed on the bottom of the dial indicator 5, an adjustable limit inspection component 7 disposed on the top of the base 1, the adjustable limit inspection component 7 includes a slide groove 71, the slide groove 71 is formed on the top of the base 1, a fixing plate 72 is slidably connected to the inner wall of the slide groove 71, a limiting rod 73 is rotatably connected to the side of the fixing plate 72, and a slot 74 is formed on the top of the base 1.

[0018] The slot 74 is located on the displacement trajectory of the limiting rod 73. There are two fixing plates 72, which are symmetrical about each other along the vertical central axis of the liner 3. The liner 3 to be tested is placed on the top of the base 1, between the two fixing plates 72. The two fixing plates 72 slide on the inner wall of the slide groove 71. When a thinner liner 3 needs to be fixed, the two fixing plates 72 are moved towards the middle along the slide groove 71 at the same time to reduce the distance between the two fixing plates 72 until they fit the liner 3 to be tested. Then the movement stops. After adjusting the position, the limiting rod 73 is rotated along the side of the fixing plate 72 towards the side closer to the slot 74. The limiting rod 73 is inserted into the slot 74 to restrict the movement of the fixing plate 72. The adjusted position of the fixing plate 72 is fixed to keep the liner 3 clamped and standing on the top of the base 1, thus improving the stability of the test.

[0019] Several slots 74 are provided and arranged in a linear array on the top of the base 1. The presence of multiple slots 74 facilitates the movement of the mounting plate 72 to any position on the base 1, allowing the mounting plate 72 to be moved to multiple positions and locked in place, thus improving adaptability.

[0020] Several limiting rods 73 are provided, arranged in pairs and symmetrically along the vertical central axis of the base 1. The measuring probe 6 is located on the top of the liner 3. The limiting rods 73 ensure the position of the fixing plate 72 and are the key to ensuring the limiting of the liner 3. The presence of several limiting rods improves the stability of the limiting.

[0021] The side of the fixing plate 72 is provided with a replaceable anti-slip component 8. The replaceable anti-slip component 8 includes a circular groove 81, which is opened on the side of the fixing plate 72. A pin 82 is provided on the inner wall of the circular groove 81. A rubber pad 83 is fixedly connected to the end of the pin 82 away from the circular groove 81. A rectangular groove 84 is opened on the side of the rubber pad 83. The circular groove 81 is opened on the side of the fixing plate 72 that is to contact the liner 3, so that the pin 82 that drives the rubber pad 83 can be inserted into it accordingly. The rubber pad 83 is inserted into the circular groove 81 along with the pin 82. The rubber pad 83 is installed on the side of the fixing plate 72. The rubber pad 83 increases the friction with the liner 3, so that the fixing plate 72 prevents the liner 3 from sliding when clamping the liner 3.

[0022] The circular groove 81 is located on the displacement trajectory of the pin 82. Several circular grooves 81 are provided, and two rubber pads 83 are provided, which are symmetrical to each other along the vertical central axis of the liner 3. Rubber pads 83 are provided on the sides of both fixing plates 72, so that the friction can be increased when the two fixing plates 72 clamp the liner 3, and further reduce slippage. The design of the circular groove 81 and the pin 82 allows the rubber pads 83 to be directly pulled out and replaced when they wear out after long-term use, without having to replace the entire fixing plate 72, thus improving the convenience of replacement.

[0023] Several rectangular grooves 84 are provided and arranged linearly on the side of the rubber pad 83. The rectangular grooves 84 are serrated and designed to provide a biting force when in contact with the liner 3, thereby reducing the risk of slippage.

[0024] One specific application of this embodiment is: Place the liner 3 to be tested on top of the base 1, between the two fixing plates 72. Depending on the thickness of the liner 3, slide the two fixing plates 72 along the inner wall of the groove 71. When a thinner liner 3 needs to be fixed, move the two fixing plates 72 simultaneously towards the center to reduce the gap until they are completely flush with both sides of the liner 3. Stop moving at this point. Next, rotate the limiting rod 73 on the side of the fixing plate 72 towards the slot 74 at the top of the base 1, inserting the limiting rod 73 into the corresponding slot 74. Since there are several slots 74 arranged in a linear array, they can accommodate any position the fixing plate 72 can move to, thus fixing the adjusted position of the fixing plate 72 and maintaining the clamping state of the liner 3, allowing the liner 3 to stand stably on the base 1. Then, adjust the dial indicator 5 on the bracket 4 so that the measuring probe 6 is in perpendicular contact with the dial indicator of the liner 3. After calibration and zeroing, pressure is applied to the liner 3 through the pressure spring assembly of the device. The slight deformation of the liner 3 is transmitted to the measuring probe 6, and the specific value is displayed by the dial indicator 5, thus completing the test. Throughout the process, the adjustable limit inspection assembly 7 achieves stable clamping of the liner 3 of different thicknesses through the cooperation of the slide groove 71, the fixed plate 72, the limiting rod 73 and the slot 74, ensuring that the liner 3 will not shift or shake during the test, improving the accuracy of the test results and the versatility of the device. Through the cooperation of the slide groove 71 and the multiple slots 74, the distance between the two fixed plates 72 can be flexibly adjusted, which can stably clamp the brake liner 3 of different thicknesses, greatly improving the versatility of the device. After the limiting rod 73 is inserted into the slot 74, it can lock the position of the fixed plate 72, which can effectively prevent the liner 3 from shifting or shaking during the test and ensure the accuracy of the measurement data.

[0025] When the fixing plate 72 needs to clamp the liner 3, first insert the pin 82 on the rubber pad 83 into the circular groove 81 on the side of the fixing plate 72, so that the rubber pad 83 is fixed on the side of the fixing plate 72 that contacts the liner 3. The several rectangular grooves 84 on the surface of the rubber pad 83 are serrated, which can provide additional biting force when in contact with the liner 3. Combined with the high friction of the rubber material itself, it can effectively prevent the liner 3 from sliding during clamping and testing, and improve the testing stability. When the rubber pad 83 wears down due to long-term use and the anti-slip effect decreases, simply pull the pin 82 out of the circular groove 81 to remove the old rubber pad 83, and then replace it with a new rubber pad. Replacement can be completed simply by inserting the pin 82 of 83 into the circular groove 81, without replacing the entire fixing plate 72. Several circular grooves 81 and pins 82 are provided to adapt to different installation requirements, further improving the convenience of replacement and the maintenance efficiency of the device. The high-friction material of the rubber pad 83, combined with the serrated rectangular groove 84, provides stronger biting force, effectively preventing the pad 3 from slipping during testing, ensuring testing stability and data accuracy. The plug-in design of the pin 82 and the circular groove 81 allows the rubber pad 83 to be directly plugged in and replaced without disassembling or replacing the entire fixing plate 72, greatly shortening maintenance time and reducing spare parts costs and waste of consumables.
