Description

Technical Field

[0001] The utility model relates to the technical field of automobile component detection, in particular to a detection device for detecting the flatness of a brake. Background Art

[0002] Automobile brakes are the braking devices of automobiles. The brakes used in automobiles are usually friction type and can be divided into two categories: drum type and disc type. With the development of the automobile industry, the demand for automobile brakes is increasing. When producing brakes, the quality requirements are becoming more and more stringent. Especially after production is completed, it is usually necessary to test the flatness of the surface.

[0003] In existing brake flatness detection devices, such as the automobile brake surface detection device disclosed in authorization announcement number CN 215767003 U, the device utilizes a raised position on the automobile brake to push a detection block upward, causing the connecting rod to drive a wedge block upward. The wedge block pushes the rack to move to both sides, causing the gear to drive the rotating frame to rotate, so that the staff can know that the automobile brake is unqualified. However, when using the detection block to detect the surface of the brake, only the obvious raised parts of the brake can be detected, and it is impossible to effectively detect minor flatness defects. As for the concave parts of the brake, it is impossible to push the detection block upward, and thus it is impossible to detect the concave parts of the brake surface. During the detection process, manual real-time adjustment of the alignment between the brake surface and the detection block is required, which is easily affected by human factors, resulting in inconsistent operation and reduced overall detection efficiency.

[0025] Example:

[0026] Reference Figure 1-4 A detection device for detecting the flatness of a brake comprises a detection platform 1, a reference panel 2 is fixedly connected to the top of the detection platform 1, an outer wall of the reference panel 2 is provided with a mounting groove, a brake disc 3 is arranged in the mounting groove, and clamping assemblies are symmetrically arranged on both sides of the brake disc 3;

[0027] Two fixed blocks 4 are symmetrically arranged on the side walls of the detection platform 1, and the two fixed blocks 4 are connected and fixed by a support rod 5. A central reference plate 6 is fixedly connected to the center of the support rod 5, and connecting blocks 7 are slidably connected to both sides of the central reference plate 6. A laser measuring instrument 8 is fixedly connected to one side of the connecting block 7. A laser emitter 9 is arranged at the bottom of the laser measuring instrument 8, and an output end of the laser emitter 9 is connected to an emission pipe 10.

[0028] The clamping assembly includes a support block 11 located at the bottom of the reference panel 2, the outer wall of the support block 11 is connected to a connecting rod 12 through a connecting shaft, the top of the connecting rod 12 is fixedly connected to a trigger handle 13, the middle part of the connecting rod 12 is connected to a balancing block 14 through a connecting shaft, one side of the balancing block 14 is connected to a connecting clamping block 15 through a connecting shaft, one end of the connecting clamping block 15 is fixedly connected to a connecting piece 16, one side of the connecting piece 16 is fixedly connected to a clamping rod 17, and the bottom of the clamping rod 17 is fixedly connected to a suction cup 18.

[0029] A laser receiver 19 is provided on the outer wall of the reference panel 2, and a center positioning rod 20 is fixedly connected to the center of the mounting groove.

[0030] A support frame 21 is fixedly connected to one side of the outer wall of the detection platform 1 , and a control panel 22 is fixedly connected to the end of the support frame 21 . The control panel 22 is provided with a control display screen and operation buttons.

[0031] A data processing system is provided inside the support frame 21 , and the control panel 22 , the laser measuring instrument 8 , the laser transmitter 9 , and the laser receiver 19 are all electrically connected to the data processing system.

[0032] The outer surface of the trigger handle 13 is covered with a rubber anti-slip protective cover.

[0033] In this embodiment, when the flatness of the brake disc 3 is tested, the center of the brake disc 3 is first aligned with the center positioning rod 20, the brake disc 3 is placed in the installation groove, and then the pulling handle 13 is pulled, so that the pulling handle 13 drives the connecting rod 12 to move downward with the connecting axis as the fulcrum. When the connecting rod 12 moves downward, the balance block 14 drives the connecting member 16 to move downward. While the connecting member 16 moves downward, it drives the clamping rod 17 and the suction cup 18 to move downward. The suction cup 18 moves downward until it contacts the brake disc 3, so that the suction cup 18 can be tightly adsorbed on the surface of the brake disc 3, thereby completing the fixation of the position of the brake disc 3 and preventing the brake disc 3 from shifting in position during subsequent testing.

[0034] Furthermore, one of the connecting blocks 7 is then moved, so that the connecting block 7 drives the laser measuring instrument 8 to move to the center reference plate 6, and then the two laser measuring instruments 8 are started in sequence. When the laser measuring instrument 8 is started, it drives the laser transmitter 9 to run, so that the laser transmitter 9 generates a laser beam, and then the laser beam is emitted and emitted from the emission pipe 10, one of the laser beams is directly irradiated vertically onto the reference panel 2, and the laser receiver 19 receives the reflected laser signal. At this time, the control panel 22 records the distance between the laser beam from the emission pipe 10 to the reference panel 2 as A, and the other laser beam is irradiated on the surface of the brake disc 3, and the distance between them is recorded as B. The difference between AB is recorded as h, which is the height between the brake discs 3, and is repeatedly moved on the support rod 5 through the connecting block 7. At the same time, the laser emitter 9 is driven to move above the brake disc 3, so that the laser beam can irradiate different surface areas of the brake disc 3, thereby performing multi-point scanning and measurement on different areas of the brake disc 3, and then using the laser receiver 19 to record the distance data h between each measuring point, and send its data to the data processing system. At the same time, the data processing system analyzes and counts the heights of all measuring points, and calculates the difference between the highest point and the lowest point, and then generates a height map, which can be intuitively displayed on the control display screen on the control panel 22, so that it can be more intuitive to observe whether the heights between the brake discs 3 are consistent, and then the flatness of the surface can be judged, and the measurement results of the flatness can be evaluated, thereby reducing human errors and improving the measurement efficiency of the detection device.
