Description

Technical Field

[0001] The present invention relates to the technical field of brake disc and pad flatness detection, and particularly relates to a detection device dedicated to brake pads of a brake. Background Art

[0002] Brake discs and pads are relatively important components in an automobile. The brake discs and pads in the prior art are mainly composed of circular disc-shaped objects, and both sides of the disc of the brake discs and pads are smooth surfaces. There are many performance indicators for measuring brake discs and pads (such as flatness, eccentricity, parallelism, balance, etc.). Among them, the surface flatness of the brake discs and pads is the most important performance indicator.

[0003] Currently, when detecting brake discs and pads, generally an error value range is preset, and most of the measuring tools for measuring the thickness of brake discs and pads use manual measurement or special measuring tools such as micrometers. That is, the brake discs and pads are fixed horizontally or vertically at a detection position, and then the brake discs and pads are detected by a micrometer. During the detection process, it is continuously compared with the error value range. When it meets the error value range, it means it is qualified, and when it does not meet the error value range, it means it is unqualified.

[0004] The above detection method has the problems that the measurement operation is cumbersome and the measurement accuracy is easily affected by the operator. Moreover, the surface area of the brake discs and pads is large. If there are depressions and protrusions in the radial direction of the brake disc and pad surface, and if the distance between the detection device and the center of the brake disc and pad is different, different detection results are likely to occur. Therefore, multiple repeated detections are required, and this method is time-consuming. For this reason, a detection device dedicated to brake pads of a brake is proposed. Summary of the Invention

[0005] In order to solve the shortcomings in the prior art, the present invention proposes a detection device dedicated to brake pads of a brake.

[0006] To achieve the above object, the present invention adopts the following technical solution: A detection device dedicated to brake pads of a brake, used for detecting the flatness of a brake disc and pad body, includes a base. An adjustment mechanism and a motor for driving the brake disc and pad body to rotate are installed on the top of the base. Two linear modules are installed on the adjustment mechanism. Detection components are fixedly installed on the sliders of the two linear modules. The two detection components are mirror-symmetrically distributed on both sides of the brake disc and pad body. The detection component includes a coating roller and a detection mechanism. The detection component includes a coating roller that can rotate around its own axis and swing radially along with the brake disc and pad body. When the coating roller rotates around its own axis, it is used for coating and detecting the depressions on the side surface of the brake disc and pad body. When the coating roller encounters a protrusion on the side surface of the brake disc and pad body, the coating roller will have a radial jump. The detection mechanism is used for detecting the radial jump of the coating roller.

[0007] Preferably, the detection assembly includes a mounting plate, a first hinge seat and a second hinge seat. The mounting plate is fixedly connected to the slider on the linear module. The first hinge seat is fixedly connected to the mounting plate. A second swing block and a first swing block are respectively rotatably mounted in the first hinge seat and the second hinge seat. Two ends of the coating roller are respectively rotatably connected to the first swing block and the second swing block. The same spring telescopic rod is hinged between the mounting plate and the second hinge seat.

[0008] Preferably, a second rotating shaft is fixedly mounted through the second swing block. The second rotating shaft passes through the first hinge seat and is rotatably connected to the first hinge seat. A first rotating shaft is fixedly mounted through the first swing block. The first rotating shaft passes through the second hinge seat and is rotatably connected to the second hinge seat. The same coating mechanism is connected to the second rotating shaft and the first rotating shaft.

[0009] Preferably, the detection mechanism includes a dial indicator and a pushing plate. The dial indicator is fixedly connected to the side of the cylinder of the spring telescopic rod. The pushing plate is fixedly sleeved on the piston rod of the spring telescopic rod. The probe end of the dial indicator abuts against the pushing plate.

[0010] Preferably, the coating mechanism includes two ear plates. Two dial indicators are respectively fixedly connected to the first rotating shaft and the second rotating shaft. The same rectangular box is fixedly mounted between the two ear plates. A coating sponge abutting against the coating roller is arranged inside the rectangular box.

[0011] Preferably, one side of the rectangular box close to the coating roller is open. A second scraping edge and a first scraping edge are respectively arranged at the top edge and the bottom edge of the opening of the rectangular box. A filling pipe is fixedly mounted through the top of the rectangular box.

[0012] Preferably, a fixing block is fixedly mounted on the output shaft of the motor.

[0013] Preferably, the adjusting mechanism includes a guide rail fixedly connected to the top of the base. A moving seat is slidably sleeved on the guide rail. A column is fixedly mounted on the top of the moving seat. A vertical plate is fixedly mounted on the column. Both linear modules are fixedly connected to the vertical plate. Four bolts distributed in a rectangle are threadedly connected through the moving seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can simultaneously detect the flatness of both sides of the brake disc body through two parallel coating rollers. By coating the brake disc body with pigment through the coating rollers, the entire side of the brake disc body can be detected simultaneously. By observing the coating condition of the pigment on the side of the brake disc body, it can be judged whether there are recesses on the side of the brake disc body. By observing whether the data displayed on the dial of the detection mechanism changes, it can be judged whether there are protrusions on the side of the brake disc body. Description of the Drawings

Specific embodiments

[0017] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-6, the present invention provides a technical solution: a detection device specifically for brake pads, which is used to detect the flatness of the brake disc body 7. It includes a base 1, an adjustment mechanism 2 is installed on the top of the base 1, and a motor 5 for driving the brake disc body 7 to rotate. Two linear modules 3 are installed on the adjustment mechanism 2. Detection components 4 are fixedly installed on the sliders of the two linear modules 3. The two detection components 4 are mirror-symmetrically distributed on both sides of the brake disc body 7. The detection component 4 includes a coating roller 46 and a detection mechanism 48. The detection component 4 includes a coating roller 46 that can rotate and swing radially along with the brake disc body 7. When the coating roller 46 rotates, it is used to coat and detect the concave parts on the side of the brake disc body 7. When the coating roller 46 encounters a convex part on the side of the brake disc body 7, the coating roller 46 will have a radial jump. The detection mechanism 48 is used to detect the radial jump of the coating roller 46.

[0019] Furthermore, the distance between the two detection components 4 can be adjusted through the two linear modules 3, so that the two detection components 4 can detect brake disc bodies 7 with different thicknesses.

[0020] The detection component 4 includes a mounting plate 41, a hinge seat one 42 and a hinge seat two 43. The mounting plate 41 is fixedly connected to the slider on the linear module 3. The hinge seat one 42 is fixedly connected to the mounting plate 41. A swing block two 45 and a swing block one 44 are respectively rotatably installed in the hinge seat one 42 and the hinge seat two 43. The two ends of the coating roller 46 are respectively rotatably connected to the swing block one 44 and the swing block two 45. The same spring telescopic rod 47 is hinged between the mounting plate 41 and the hinge seat two 43.

[0021] Furthermore, when the coating roller 46 is in close contact with the brake disc body 7, then as the brake disc body 7 rotates, under the action of friction, the rotating brake disc body 7 will drive the coating roller 46 to rotate.

[0022] A rotating shaft two 451 is fixedly installed through the swing block two 45. The rotating shaft two 451 passes through the hinge seat one 42 and is rotatably connected to the hinge seat one 42. A rotating shaft one 441 is fixedly installed through the swing block one 44. The rotating shaft one 441 passes through the hinge seat two 43 and is rotatably connected to the hinge seat two 43. The same coating mechanism 49 is connected to the rotating shaft two 451 and the rotating shaft one 441.

[0023] The detection mechanism 48 includes a dial indicator 481 and a push plate 482. The dial indicator 481 is fixedly connected to the side of the cylinder of the spring telescopic rod 47. The push plate 482 is fixedly sleeved on the piston rod of the spring telescopic rod 47. The probe end of the dial indicator 481 abuts against the push plate 482.

[0024] The coating mechanism 49 includes two ear plates 491. Two dial indicators 481 are respectively fixedly connected to the first rotating shaft 441 and the second rotating shaft 451. A same rectangular box 492 is fixedly installed between the two ear plates 491. A coating sponge 493 that abuts against the coating roller 46 is provided inside the rectangular box 492.

[0025] One side of the rectangular box 492 close to the coating roller 46 is open. A second scraping edge 496 and a first scraping edge 495 are respectively provided at the top edge and the bottom edge of the opening of the rectangular box 492. A filling pipe 494 is fixedly installed through the top of the rectangular box 492.

[0026] Further, the rotation direction of the coating roller 46 is from the second scraping edge 496 to the first scraping edge 495. The second scraping edge 496 can scrape and clean the surface of the second scraping edge 496, so that the clean part of the surface of the coating roller 46 can contact the coating sponge 493. After the coating sponge 493 coats the pigment on the coating roller 46, the first scraping edge 495 then scrapes off the excess pigment on the coating roller 46, so that the pigment can be evenly coated on the coating roller 46 and then contact the surface of the brake disc body 7. Pigment can be filled into the coating sponge 493 through the filling pipe 494.

[0027] Further, the coating roller 46 is made of metal, and the surface of the coating roller 46 is subjected to frosted treatment (which is beneficial to the adhesion of the pigment, and after the frosted treatment, the friction between it and the side surface of the brake disc body 7 can be increased, so that the brake disc body 7 can drive the abutting coating roller 46 to rotate while rotating itself). After the pigment attached to the coating roller 46 is scraped by the first scraping edge 495, the pigment on the coating roller 46 is a thin layer, and the excess pigment will be adsorbed by the coating sponge 493 again. When the side surface of the brake disc body 7 is flat, the coating roller 46 is in close contact with the side surface of the brake disc body 7, so that the pigment attached to the coating roller 46 can adhere to the side surface of the brake disc body 7 through the extrusion between the two. If there are pits on the side surface of the brake disc body 7, since the pits are not in contact with the coating roller 46, the pigment on the coating roller 46 adheres to the pits. And because the pigment attached to the coating roller 46 is limited, when the pigment adheres to the side surface of the brake disc body 7, it will not flow, so that the pigment on the flat part of the side surface of the brake disc body 7 will not flow into the pits.

[0028] A fixing block 6 is fixedly installed on the output shaft of the motor 5.

[0029] Further, the fixing block 6 is provided with clamping holes suitable for the mounting holes on various brake disc bodies 7. During use, the fastener is passed through the mounting holes on the brake disc body 7 and then screwed into the corresponding assembly holes, and the brake disc body 7 can be clamped and fixed on the fixing block 6.

[0030] The adjusting mechanism 2 includes a guide rail 21 fixedly connected to the top of the base 1. A moving seat 22 is slidably sleeved on the guide rail 21. A column 24 is fixedly installed on the top of the moving seat 22. A vertical plate 25 is fixedly installed on the column 24. Both linear modules 3 are fixedly connected to the vertical plate 25. Four bolts 23 distributed in a rectangular shape are threadedly connected through the moving seat 22.

[0031] Further, by loosening the four bolts 23, the installation position of the moving seat 22 on the guide rail 21 can be adjusted, so that the distance between the two detection components 4 and the fixed block 6 can be adjusted accordingly according to the brake disc body 7 with different sizes.

[0032] In this embodiment: when detecting the flatness of the brake disc body 7, the brake disc body 7 is fixed on the fixed block 6 by a fastener passing through the installation hole positions on the brake disc body 7. Then, the two linear modules 3 are controlled to drive the two detection components 4 to approach each other, so that the two coating rollers 46 arranged in parallel are respectively in close contact with both sides of the brake disc body 7; Then, the motor 5 is started. The motor 5 drives the brake disc body 7 to rotate self - by the fixed block 6. The rotating brake disc body 7 will drive the two coating rollers 46 in contact with it to rotate. When there is a protrusion on the side surface of the brake disc body 7, the protrusion will push the coating roller 46 to swing around the rotation axis two 451. During this process, the hinge seat two 43 will move away from the brake disc body 7 and squeeze the spring telescopic rod 47, so that the piston rod of the spring telescopic rod 47 contracts into the cylinder of the spring telescopic rod 47. At this time, the top - push plate 482 will push the probe of the dial indicator 481, so that the numerical change is shown on the dial of the dial indicator 481. Therefore, the staff can detect the protrusion on the brake disc body 7 as long as they observe the change in the dial display of the dial indicator 481; When the brake disc body 7 rotates self - by, it will drive the coating roller 46 to rotate self - by at the same time. When the coating roller 46 rotates self - by, the paint in the coating mechanism 49 will be evenly coated on the coating roller 46. The coating roller 46 in contact with the brake disc body 7 will coat the paint on the surface of the brake disc body 7 during the rotation process. If the surface of the brake disc body 7 is flat, the paint will be evenly coated on the surface of the brake disc body 7. If there are pits on the surface of the brake disc body 7, since the paint on the coating roller 46 cannot be coated into the pits, the staff only need to observe whether there are uncoated places on the surface of the brake disc body 7 to detect whether there are pits on the surface of the brake disc body 7. After the detection is completed, the staff only need to clean the paint coated on the brake disc body 7.

[0033] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
