Technical Field

[0001] The present invention relates to the technical field of brake disc detection, and in particular to a brake disc defect detection device. Background Art

[0002] As a core component of the automobile braking system, the quality of the brake disc is directly related to the braking effect of the car and the safety of the driver and passengers. Brake disc camera defect detection mainly uses high-resolution industrial cameras to capture images of the brake disc surface, and then analyzes these images through image processing algorithms and machine learning models to identify defects on the brake disc. During the production and processing of brake discs, impurities such as scraps will remain on them. If they are not cleaned in time, the impurities will block the brake disc, which will affect the camera's detection of defects on the brake disc surface. Summary of the invention

[0020] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.

[0021] like Figure 1-6 As shown, the present invention provides a brake disc defect detection device, including a workbench 1, a detection camera 2, a clamping mechanism 4 and a cleaning mechanism 5, the detection camera 2 is arranged on the front side of a bracket 11 on the workbench 1, the bracket 11 is provided with a light source 3 directly below the detection camera 2, the clamping mechanism 4 is arranged on a fixed seat 12 on the workbench 1 and is used to fix the brake disc to be detected, and the cleaning mechanism 5 is arranged on the clamping mechanism 4 and is used to clean impurities on the brake disc to be detected.

[0022] It should be noted that the clamping mechanism 4 includes a driving motor 42, a right clamping ring 44, a left clamping ring 46 and a cylinder 45. The fixed seat 12 is rotatably connected with a rotating shaft 41. The driving motor 42 is installed on the fixed seat 12 and its output shaft is connected to one end of the rotating shaft 41 through a coupling 43. The right clamping ring 44 is arranged at the other end of the rotating shaft 41. The cylinder body of the cylinder 45 is installed at one end of the right clamping ring 44 and its piston rod end is connected to one end of the left clamping ring 46. The other end of the left clamping ring 46 is slidably connected to the guide rod 47 at the other end of the right clamping ring 44. The end of the guide rod 47 is provided with a retaining ring 48. The right clamping ring 44 and the left clamping ring 46 are both provided with a clamping groove 441 for clamping the brake disc to be tested, and the brake disc is clamped and fixed by the clamping groove 441.

[0023] In addition, the cleaning mechanism 5 includes a valve 51, a slide rod 55 and a spring 58. One end of the valve 51 is communicated with the air cavity in the left clamping ring 46 through a hard main pipe 52, and the other end of the valve 51 is connected with an air pump through a hose 53. A plurality of spray nozzles 54 facing the brake disc are symmetrically arranged on the upper and lower sides of the clamping groove 441 of the left clamping ring 46. The spray nozzles 54 are communicated with the air cavity in the left clamping ring 46. The slide rod 55 is slidably connected to the fixing bracket 56 outside the left clamping ring 46 and the left clamping ring 46. The fixing bracket 56 is of a "U" - shaped structure and is arranged with the opening facing the left clamping ring 46. An arc - shaped pressing plate 57 located in the clamping groove 441 is arranged at the inner end of the slide rod 55. The spring 58 is sleeved on the slide rod 55 and is located between the fixing bracket 56 and the upper stop disc 551 of the slide rod 55. A rack 59 meshing with the gear 511 on the valve stem of the valve 51 is arranged on the side of the slide rod 55.

[0024] Specific implementation method and principle:

[0025] When detecting the brake disc, the worker places the brake disc between the right clamping ring 44 and the left clamping ring 46, and controls the piston rod of the air cylinder 45 to retract, driving the left clamping ring 46 to move along the guide rod 47 on the right clamping ring 44, and clamping the brake disc through the clamping grooves 441 on the inner sides of the right clamping ring 44 and the left clamping ring 46.

[0026] During the clamping process, the brake disc presses the arc - shaped pressing plate 57 at the inner end of the slide rod 55, causing the slide rod 55 to move outward. The rack 59 on the side of the slide rod 55 drives the valve stem of the valve 51 to rotate, opening the valve 51. The spring 58 on the slide rod 55 is compressed, and the gas enters the left clamping ring 46 through the hard main pipe 52 and is sprayed onto the upper and lower sides of the brake disc through the spray nozzles 54 on the inner side of the left clamping ring 46 to clean the surface impurities of the brake disc.

[0027] The detection camera 2 takes a photo of one side of the brake disc. When the photo detection of one side of the brake disc is completed, the output shaft of the driving motor 42 drives the rotating shaft 41 on the fixed seat 12 to rotate, turning the brake disc over, and the detection camera 2 takes a photo of the other side of the brake disc.

[0028] When the detections of both sides of the brake disc are completed, control the piston rod of the air cylinder 45 to extend, driving the left clamping ring 46 to move along the guide rod 47, so that the left clamping ring 46 releases the brake disc. During the movement of the left clamping ring 46, under the elastic force of the spring 58 on the slide rod 55, the arc - shaped pressing plate 57 continues to press the brake disc in the clamping groove 441 of the right clamping ring 44, keeping the brake disc stable in the right clamping ring 44. During the movement of the slide rod 55, the rack 59 on the slide rod 55 drives the gear 511 on the valve stem of the valve 51 to rotate in the reverse direction, closing the valve 51.

[0029] When the left clamp ring 46 continues to move, it drives the arc-shaped pressure plate 57 to separate from the brake disc. The worker removes the brake disc from the right clamp ring 44 and replaces it with a new brake disc to be tested.

[0030] To summarize, in the present application, the cylinder 45 of the clamping mechanism 4 enables the left clamping ring 46 and the right clamping ring 44 to clamp and fix the brake disc. In the process of clamping and fixing the brake disc, the slide rod 55 and the rack 59 are driven to move to open the valve 51. The gas passes through the nozzle 54 in the left clamping ring 46 to clean the impurities on the upper and lower surfaces of the brake disc, so that the detection camera 2 can accurately detect both sides of the brake disc. After the detection, the left clamping ring 46 is controlled by the cylinder 45 to move away from the right clamping ring 44. In the process of moving, the arc-shaped pressure plate 57 continues to press the brake disc to avoid the brake disc being released immediately after the left clamping ring 46 moves, leaving enough safe space and time for the workers to remove the brake disc, driving the valve stem of the valve 51 to rotate in the opposite direction to close the valve 51.

[0031] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
