Description

Technical Field

[0001] This utility model belongs to the technical field of flatness testing devices, and particularly relates to a flatness testing device for brake disc production. Background Technology

[0002] A brake disc, simply put, is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you press the brake pedal, it is the caliper that clamps the brake disc to slow down or stop the car. During the production process of brake discs, their flatness needs to be tested to avoid uneven surfaces affecting braking performance. This requires the use of a flatness testing device for auxiliary testing.

[0003] Traditional flatness testing uses physical methods such as laser detection, which involves projecting a laser beam onto one side of the brake disc and determining flatness based on the position of the beam. This method requires constantly moving the laser beam to assess the flatness of the brake disc, and for disc-shaped brake discs, it requires multiple disassemblies and reassemblies of the brake disc and clamping structure to test flatness at different locations, which is very inconvenient. To solve these problems, there is an urgent need for a flatness testing device for brake disc production. Summary of the Invention

[0004] The purpose of this invention is to address the problem that traditional flatness testing methods, such as laser testing, are used to detect flatness. These methods involve shooting a laser beam along one side of the brake disc and determining flatness based on the position of the beam. However, this requires constantly moving the laser beam to determine the flatness of the brake disc, and for disc-shaped brake discs, it requires multiple disassemblies and reassemblies of the brake disc and clamping structure to test the flatness of different positions on the brake disc, which is very inconvenient. Therefore, this invention proposes a flatness testing device for brake disc production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flatness testing device for brake disc production includes a base and a brake disc body. A control cabinet is installed on one side of the base, a clamping and rotating assembly is installed on the top of the base, and an adjustment and testing assembly is installed on one side of the base. The clamping and rotating assembly includes a placement disc and a drive motor. A rotating rod is fixedly connected to the output end of the drive motor, and a mounting disc is fixedly connected to the top end of the rotating rod. The brake disc body is placed above the placement disc. The adjustment and testing assembly includes a U-shaped plate, an auxiliary rod is rotatably connected between the two sides of the U-shaped plate, a rotating block is fixedly connected to the outer surface of the auxiliary rod, and a laser head is fixedly connected to the outer surface of the rotating block.

[0006] As a further description of the above technical solution: The base has a mounting groove on one side, the drive motor is mounted on the top of the mounting groove, a sliding rod is fixedly connected to the bottom of the mounting plate, and an annular groove is provided on the top of the base, with the sliding rod slidably disposed on the inner wall of the annular groove.

[0007] As a further description of the above technical solution: A threaded clamp rod is fixedly connected to the top of the mounting plate, and a threaded clamping hole is provided at the bottom of the placement disc. The threaded clamp rod and the threaded clamping hole are threadedly connected.

[0008] As a further description of the above technical solution: An L-shaped plate is fixedly connected to the outer surface of the disc. A threaded extrusion rod is threadedly connected to one side of the L-shaped plate. An operating block is fixedly connected to one end of the threaded extrusion rod, and an extrusion block is fixedly connected to the other end of the threaded extrusion rod.

[0009] As a further description of the above technical solution: One end of the auxiliary rod is fixedly connected to an operating circular plate, one side of the operating circular plate is threadedly connected to a threaded rod, one end of the threaded rod is fixedly connected to a rubber block, and one side of the U-shaped plate is fixedly connected to an annular plate.

[0010] As a further description of the above technical solution: A rectangular plate is fixedly connected to one side of the base, and a threaded auxiliary rod is rotatably connected to the top of the rectangular plate. A threaded hole plate is threadedly connected to the outer surface of the threaded auxiliary rod. A fixing rod is fixedly connected to the top of the rectangular plate, and a sliding cylinder is slidably connected to the top end of the fixing rod. The threaded hole plate is fixedly connected to the sliding cylinder.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting a clamping and rotating assembly, the placement disc and the mounting disc can be disassembled and assembled under the action of the threaded clamping rod and the threaded clamping hole. Under the action of the drive motor, the placement disc can be rotated. Thus, during the detection process, X-rays can be injected from one direction. By rotating the placement disc, the flatness can be detected. By observing whether the exit position of the X-rays changes, it can be determined whether the overall flatness meets the requirements.

[0012] 2. In this utility model, by setting a threaded extrusion rod, the extrusion block can be driven to move, thereby limiting the brake disc body placed on the disc, so that the brake disc body will shift its position during rotation.

[0013] 3. In this utility model, by setting an adjustment and detection device, the sliding cylinder can be driven to slide on the outer surface of the fixed rod under the action of the threaded auxiliary rod, so that the height position of the U-shaped plate can be adjusted. At the same time, with the cooperation of the auxiliary rod and the rotating block, the angle of the laser head can be adjusted, so that the angle of the radiation intake can be adjusted.

The sliding rod 45 is slidably positioned on the annular groove 46. The inner wall of the groove 46 has a threaded clamping rod 413 fixedly connected to the top of the mounting plate 44. The bottom of the placement disc 47 has a threaded clamping hole 48. The threaded clamping rod 413 and the threaded clamping hole 48 are threadedly connected. When the threaded clamping rod 413 and the threaded clamping hole 48 are fixed, the placement disc 47 and the mounting plate 44 can be fixed. An L-shaped plate 49 is fixedly connected to the outer surface of the placement disc 47. A threaded pressing rod 410 is threadedly connected to one side of the L-shaped plate 49.
