Description

Technical Field

[0001] This utility model relates to the field of brake disc processing and testing technology, and in particular to a brake disc laser marking and rating agency. Background Technology

[0002] As a key component of the automotive braking system, the performance and quality of brake discs directly affect vehicle safety. During the production and factory inspection of brake discs, it is typically necessary to test their appearance, dimensions, tolerances, and other aspects, and to classify and manage products based on the test results. To ensure product quality traceability, qualified products are also marked with codes on their surface to facilitate subsequent sorting, distribution, and after-sales tracking.

[0003] In existing technologies, brake disc grading and marking are mostly done manually, which suffers from low efficiency, poor consistency, and high error rates. Meanwhile, some automated equipment is complex in structure, cumbersome to operate, and occupies a large space, making it difficult to meet the needs of small and medium-sized brake disc manufacturers for efficient, stable, and highly automated testing and marking equipment. Furthermore, existing devices still have room for optimization in brake disc positioning, rotation, and heat dissipation, affecting the continuity of their operation and system stability.

[0004] Therefore, there is an urgent need to provide a mechanism that is structurally sound, stable in operation, easy to use, and capable of automatically positioning, grading, and coding brake discs, in order to improve detection efficiency and grading accuracy and solve the problems existing in current technologies. Utility Model Content

[0005] The purpose of this invention is to provide a brake disc laser marking and rating mechanism to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a brake disc laser marking and rating mechanism, comprising a stepper motor, a rotary worktable, a brake disc fixing bracket, a brake disc fixing block, a cooling fan, a central control unit, a positioning laser sensor, a brake disc rating device, and a cabinet. The stepper motor drives the rotary worktable to rotate and achieve fixed angle control. Multiple brake disc fixing brackets are fixedly connected to the rotary worktable, and each brake disc fixing bracket is provided with a brake disc fixing block. The brake disc fixing block is composed of two coaxially connected cylinders, the diameter of the upper cylinder matching the diameter of the center hole of the brake disc to be tested, and has a through hole inside for installation. The positioning laser sensor detects whether the brake disc fixing block has rotated to a preset detection position and sends a signal to the central control unit. The central control unit controls the start and stop of the stepper motor and controls the brake disc rating device to perform quality rating and laser marking when the brake disc is in the detection position. The cooling fan is arranged on both sides of the cabinet for ventilation and heat dissipation of the stepper motor.

[0007] According to the above technical solution, the rotating worktable is provided with three brake disc fixing brackets, and the three brake disc fixing brackets are symmetrically arranged on the rotating worktable at 120-degree intervals.

[0008] According to the above technical solution, the brake disc fixing bracket is composed of three rectangular steel or iron components, which are welded and fixed on the rotating worktable.

[0009] According to the above technical solution, in the brake disc fixing block, the diameter of the lower cylinder is larger than the diameter of the upper cylinder, and an axial through hole is provided in the middle of the upper and lower cylinders.

[0010] According to the above technical solution, there are four cooling fans, which are symmetrically distributed on the left and right sides of the cabinet.

[0011] According to the above technical solution, the positioning laser sensor is installed above the rotation path of the brake disc.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model, by setting up a stepper motor, a rotary worktable, a brake disc fixing bracket and fixing block, a positioning laser sensor, a central control panel, a brake disc rating device and a cooling fan, realizes the automatic positioning, rotation, rating and laser marking functions of the brake disc.

[0013] (1) The movement of the rotary table is precisely controlled by a stepper motor, so that the brake disc rotates to the detection position in sequence. Combined with the laser sensor, high-precision stopping is achieved, which improves the accuracy and consistency of detection and coding.

[0014] (2) The brake disc fixing block adopts a coaxial cylindrical structure, which is highly versatile, easy to install and remove, and compatible with various models of brake discs.

[0015] (3) The central control console integrates control logic and human-machine interaction functions, enabling automatic control and real-time display of the equipment;

[0016] (4) Cooling fans are reasonably distributed on both sides of the cabinet to ensure that the internal temperature remains stable during operation, thereby improving the overall stability and service life of the system.

[0026] 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.

[0027] Example:

[0028] Reference Figure 1-6 A brake disc laser marking and rating mechanism includes a stepper motor 1, a rotary table 2, brake disc fixing brackets 21, brake disc fixing blocks 22, a cooling fan 3, a central control unit 4, a positioning laser sensor 5, a brake disc rating device 6, and a cabinet 7. The stepper motor 1 is installed inside the cabinet 7 and is used to drive the rotary table 2 to rotate around the central axis. The stepper motor 1 and the rotary table 2 are mechanically fixedly connected to realize the driving and deceleration control of the rotary table 2. The rotary table 2 is disc-shaped and fixedly connected to the output shaft of the stepper motor 1. Three brake disc fixing brackets 21 are symmetrically arranged at 120-degree intervals on the circumference edge of the rotary table 2 for installing the brake disc fixing blocks 22. Each brake disc fixing bracket 21 is composed of three rectangular components, preferably made of steel or iron. The three rectangular components are vertically welded above the rotary table 2 and the brake disc fixing blocks 22 are welded to the top.

[0029] The brake disc fixing block 22 consists of two coaxial cylinders connected vertically. The diameter of the upper cylinder is equal to the diameter of the brake disc mounting hole, while the diameter of the lower cylinder is larger than that of the upper cylinder. The two cylinders are fixedly connected by welding or integral processing. A through hole is provided in the middle for positioning and installing the brake disc. Two cooling fans 3 are installed on each of the left and right sides of the cabinet 7, for a total of four cooling fans 3, to ventilate and dissipate the heat generated by the stepper motor 1 during operation, preventing overheating and unstable operation. The positioning laser sensor 5 is installed above the rotation path of the brake disc to detect in real time whether the brake disc fixing block 22 has rotated to the target detection position. When the brake disc fixing block 22 is detected to be in the set position, the positioning laser sensor 5 sends a control command to the control console 4 via a signal connection, causing the stepper motor 1 to stop working.

[0030] The brake disc rating device 6 is fixed in the internal detection area of ​​the cabinet 7. It is used to identify the rating of the brake disc after positioning. The detection items include, but are not limited to, the appearance, thickness and preset technical parameters of the brake disc. The rating results are transmitted to the central control console 4 for recording. The central control console 4 is the main control module of the device. It integrates the operation interface, processor, input and output interfaces, etc., and uniformly schedules the workflow of the stepper motor 1, the positioning laser sensor 5 and the brake disc rating device 6 to realize the automatic rotation, positioning, rating and subsequent data processing of the brake disc.

[0031] This invention achieves automatic coding and grading of brake discs through the above structure, and features simple structure, high control precision and wide applicability. It is suitable for quality grading and marking management of batch brake discs.

[0032] In operation, the operator sequentially installs the brake discs to be tested into the brake disc fixing blocks 22 on the rotary table 2. Each brake disc is positioned by an interference fit with the upper cylinder, ensuring stability during subsequent rotation and rating. After the device is started, the stepper motor 1 drives the rotary table 2 to rotate gradually at preset angular intervals. When any brake disc moves with the rotary table to the detection position corresponding to the laser sensor 5, the positioning laser sensor 5 sends a position confirmation signal, which is received by the central control unit 4 and a control command is issued to stop the stepper motor 1. After the rotary table stops, the brake disc rating device 6 immediately starts to perform multi-dimensional parameter rating assessments on the brake discs located at the testing station. The assessment process includes appearance defect identification, edge wear detection, and thickness consistency judgment. Based on the test results, the rating device can use laser marking technology to engrave the corresponding rating mark on the surface of the brake disc. After marking and rating are completed, the central control unit 4 controls the stepper motor 1 to continue running, causing the rotary table 2 to rotate the next brake disc fixing block 22 to the testing position, repeating the above rating process until all brake discs have been tested.

[0033] Throughout the operation, the cooling fans 3 located on both sides of the cabinet 7 continuously run to ventilate and cool the core components such as the stepper motor 1, ensuring stable operation of the device under high load for extended periods. After the inspection is completed, the operator removes the rated brake disc, thus completing the work process.
