Description

Technical Field

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

[0002] The brake disc is one of the key components of the automobile braking system. It is usually made of cast iron or cast steel. It is installed in the brake device on the wheel and cooperates with the brake pad of the brake system to achieve the braking effect. The function of the brake disc is to convert the vehicle's kinetic energy into heat energy through the resistance generated by friction, and slow down or stop the vehicle. When the driver steps on the brake pedal, the brake system will apply pressure to make the brake pad and brake disc rub against each other, thereby slowing down or stopping the vehicle. After production or grinding and repair, its working surface should be flat and needs to be inspected.

[0003] Existing brake disc inspection uses sampling equipment for testing.

[0036] The scraping assembly located on the lower side is arranged below the bottom side housing 3 .

[0037] When using this equipment to test the brake disc, first place the brake disc to be tested on the turntable 19, align each insertion rod 20 with the mounting hole on the brake disc, then rotate the second screw 23 through the rocker arm 24, the second screw 23 drives the slide plate 18 to move, the slide plate 18 drives the turntable 19 and the brake disc thereon to move to the detection mechanism area, then start the motor 31, the motor 31 drives the transmission shaft 16 to rotate, the transmission shaft 16 drives the two first screws 13 to rotate respectively through two sets of gear sets 17, the two trusses 15 approach each other, so that the four sets of pressurizing components are respectively in contact with the working surface areas on the upper and lower sides of the brake disc, so that a closed space is formed between the roller 4, the sealing belt 7, the shell 3 and the working surface of the brake disc, then the pump body device 10 is started, and the fluorescent liquid is injected into the closed space through the hose 12 and the conduit 11, and a certain pressure is maintained to ensure that the fluorescent liquid is sealed in the closed space.

[0038] After the fluorescent liquid is injected, the servo motor 8 is started through the control device 2, the servo motor 8 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the roller 4 to rotate, the roller 4 drives the sealing belt 7 to rotate, thereby driving the brake disc to rotate. When the brake disc rotates, its working surface is coated with fluorescent liquid. Due to the pressure, the fluorescent liquid is pressed into the crack area. After the fluorescent liquid is coated, the pump body device 10 draws the fluorescent liquid in the closed space back.

[0039] After the fluorescent liquid is withdrawn, the electric telescopic cylinder 27 is started, which deflects the connecting frame 26, so that the scraper 25 contacts the working surface of the brake disc and scrapes off the fluorescent liquid on the working surface. However, fluorescent liquid will still remain in the crack area or the worn point area.

[0040] After the surface is scraped clean, start the motor 31 to reverse, turn off the servo motor 8, move the two trusses 15 away from each other, release the pressure, and reversely rotate the second screw 23 through the rocker arm 24 to move the slide plate 18, so that the brake disc after the inspection mark is transferred to the area where the lighting group 30 is located. After being illuminated by the lighting group 30, if there are cracks or pits in the worn area, it will display a bright fluorescent color, thereby realizing the detection of the brake disc.

[0041] Through the above method, the brake disc can be inspected on the surface area, thereby covering the working surface area of ​​the brake disc, achieving full inspection and improving efficiency.

[0042] After detection, fluorescent liquid will remain in the gap area or the pit wear area, so it will be marked and can be identified by the light group 30, so as to facilitate further processing later.

[0043] When one turntable 19 is in the area of ​​the light group 30, the other turntable 19 is in the area of ​​the detection mechanism, so that the other brake disc can be detected to improve the detection efficiency.

[0044] The four sets of pressure components are symmetrically arranged vertically, which can make the brake disc evenly stressed, and the marks on both sides are detected at the same time to further improve efficiency.

[0045] The fluorescent fluid itself has no effect on the brake disc itself, it only serves as a marking detection function.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
