Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts inspection devices, specifically to a brake disc inspection device. Background Technology

[0002] Brake discs are a key component of automotive braking systems, and their quality and performance directly affect vehicle safety and driving experience. Brake discs are usually made of cast iron or carbon fiber materials, which have excellent wear resistance and heat resistance. In order to ensure the braking effect of the vehicle under various conditions, it is particularly important to conduct factory testing on the brake discs.

[0003] The main purpose of brake disc inspection is to assess its wear level, surface condition, and thermal fade performance to ensure its safety and reliability during use. Traditional brake disc inspection methods include visual inspection, thickness measurement, and surface hardness testing. However, these methods are mostly performed manually, relying on the naked eye and long-term experience, and have drawbacks such as low inspection accuracy, long inspection cycle, and susceptibility to human factors affecting the inspection results.

[0004] With the rapid development of the automotive industry and the continuous improvement of vehicle performance, the requirements for brake disc testing technology are becoming increasingly stringent. Traditional testing methods are no longer sufficient to meet the high quality and performance requirements of modern automotive braking systems. Currently, to achieve efficient testing, a dial indicator is typically used to inspect the brake disc. However, most dial indicators still require manual holding to operate, rather than clamping and fixing the brake disc in the correct position and then rotating it for testing. This affects ease of use and causes inconvenience to the user. Therefore, we propose a brake disc inspection device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-4This utility model provides a technical solution: a brake disc inspection device, including a base plate 1, a second cylinder 14 fixedly installed at the top center of the base plate 1, a vertical plate 11 fixedly installed on the top front side of the base plate 1, an electric slide table 12 fixedly installed on the top of the vertical plate 11, a first cylinder 13 fixedly installed on the slide of the electric slide table 12, and horizontal plates 15 fixedly installed on the telescopic shafts of both the first cylinder 13 and the second cylinder 14. Dial gauges 151 are fixedly installed on the two horizontal plates; the dial gauge 151 at the first cylinder 13 is horizontally positioned, and the dial gauge 151 at the second cylinder 14 is vertically positioned. The electric slide table 12 is existing technology, and its principle is to use a motor to drive a lead screw to rotate, which in turn drives the slide table to move through the threaded engagement of the lead screw and the slider.

[0027] In use, the first cylinder 13 and the second cylinder 14 drive the two dial indicators 151 to press against the side and circumference of the brake disc respectively. The measuring rod on the dial indicator 151 moves slightly linearly due to the size being measured. This movement is amplified by gear transmission and becomes the rotation of the pointer on the scale, thereby reading the size of the measured dimension and realizing the size detection operation of the brake disc.

[0028] Specifically, a vertical beam 18 is fixedly installed on the top rear side of the base plate 1. A clamping assembly 2 is provided on the vertical beam 18. The clamping assembly 2 includes a first servo motor 20 fixedly installed on the top of the vertical beam 18. The output shaft of the first servo motor 20 rotates through the top of the vertical beam 18 and is fixedly installed on a guide rail 21. A second servo motor 22 is fixedly installed at the end of the guide rail 21. The guide rail 21 has a hollow structure inside. A forward lead screw 23 and a reverse lead screw 24 are rotatably connected together inside the guide rail 21. The output shaft of the second servo motor 22 rotates through and extends into the interior of the guide rail 21 and is fixedly connected to one end of the forward lead screw 23. Slider 25 is threadedly connected to both the forward lead screw 23 and the reverse lead screw 24. The ends of the two sliders 25 slide through and extend to the front outer side of the guide rail 21 and are fixedly installed with clamping rods 26. In use, the second servo motor 22 drives the forward lead screw 23 and the reverse lead screw 24 to rotate, thereby driving the two sliders 25 to move in opposite directions. This allows the two clamping rods 26 to clamp the brake disc. In addition, the first servo motor 20 can rotate the brake disc for detection.

[0029] In this embodiment, multiple support legs 10 arranged in a matrix are fixedly installed on the bottom surface of the base plate 1. The height of the support legs 10 is greater than 30cm, so that stable support operation can be achieved by using the support legs 10.

[0030] Specifically, guide posts 16 are fixedly installed on both horizontal plates 15, and guide sleeves 17 are slidably connected to the outer side of both guide posts 16. The other ends of the two guide sleeves 17 are respectively fixedly installed on the top surface of the corresponding base plate 1 and the sliding seat of the electric slide table 12. The sliding cooperation between the guide posts 16 and the guide sleeves 17 guides the movement of the horizontal plates 15.

[0031] Furthermore, a steel plate 201 is fixedly mounted on the output shaft of the first servo motor 20, and a guide rail 21 is fixedly mounted on the rear side of the steel plate 201 by multiple fastening screws, which facilitates the fixed installation of the guide rail 21.

[0032] In addition, a groove 211 is provided inside the guide rail 21 along the length of the guide rail 21. The end of the slider 25 passes through the groove 211 and is slidably connected to the groove 211. The cross-sections of both the slider 25 and the groove 211 are T-shaped. The size of the slider 25 is matched with the size of the groove 211, making the slider 25 more stable and smooth when moving.

[0033] It is worth noting that limit plates 27 are fixedly installed on the ends of the two clamping rods 26 away from the guide rail 21. The two limit plates 27 are respectively located on the two opposite sides of the two clamping rods 26, and anti-slip layers 261 are provided on both opposite sides of the clamping rods 26. The anti-slip layers 261 can play an anti-slip protection role, making the clamping of the brake disc more stable.

[0034] It is worth noting that the first cylinder 13 is at the same height as the guide rail 21, and the second cylinder 14 is located below the clamping rod 26, which facilitates the two dial indicators 151 to be placed against the side and circumference of the brake disc for testing.

[0035] In use, the brake disc inspection device of this utility model involves passing the ends of the two clamping rods 26 through the through hole at the center of the brake disc. Then, the second servo motor 22 is connected to an external power source and put into operation. The output shaft of the second servo motor 22 rotates, driving the forward lead screw 23 and the reverse lead screw 24 to rotate. The rotation of the forward and reverse lead screws 23 and 24 moves the two sliders 25, further causing the two clamping rods 26 to press against the inner annular side of the brake disc, completing the clamping operation. After clamping and fixing, the first cylinder 13 and the second cylinder 14 are activated, extending their telescopic shafts to move the contacts on the dial indicator 151 to the corresponding positions on the brake disc. Then, the first servo motor 20 is connected to an external power source and put into operation. The output shaft of the first servo motor 20 rotates, driving the guide rail 21, the clamping rods 26, and the brake disc to rotate, thus enabling the inspection of the side and circumferential surfaces of the brake disc using the two dial indicators 151.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
