[0002] Brake discs, also known as brake discs, directly reflect the effectiveness of braking. There are many performance indicators for measuring brake discs, such as thickness variation, eccentricity, parallelism, and balance. Thickness uniformity and surface smoothness are two key performance indicators.

A protective shell is installed on the outer wall of the brake disc, the interior of the protective shell is hollow, and is used to install a capacitive sensor and a receiving probe, and the capacitive sensor is connected to the internal components of the controller through a wire passing through the protective shell. The capacitive sensor is a component inside the capacitive thickness detection module, and the thickness of the brake disc can be detected in real time through the capacitive thickness detection module. The receiving probe is used to receive ultrasonic waves sent by a transmitting probe installed on the surface of the brake disc. The ultrasonic sensor can detect whether there are cracks in the brake disc through the receiving probe. Testing the brake disc before the car is driven can ensure the normal use of the brake disc and prevent accidents. This invention has the characteristic of facilitating real-time detection of the brake disc.

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.
[0035] The invention provides Figures 1 to 8 As shown, an automatic detection device for automobile brake discs includes:
[0036] The conveying device 11 and the detection mechanism 2 are arranged on the conveying device 11 and detect the thickness of the brake disc 31 on the conveying path of the conveying device 11. The conveying device 11 intermittently conveys multiple groups of brake discs 31;
[0037] The detection mechanism 2 includes a support base 23, a detection contact 24, and a detection camera. The support base 23 and the detection contact 24 are used to directly contact the brake disc 31 to detect thickness, and the detection camera is used to optically photograph the brake disc 31 to detect thickness. The support base 23 is used to lift and support a brake disc 31 on the conveying path, thereby cooperating with the detection contact 24 to detect the thickness of the surface of the brake disc 31.
[0038] The detection mechanism 2 includes a driving push rod 3 211, and the telescopic rod of the driving push rod 3 211 is installed with a positioning rod 213 through a connecting piece 212. The positioning rod 213 is used to position the brake disc 31 to be detected on the support seat 23, thereby preventing the brake disc 31 from being offset and causing detection errors.
[0039] Working principle: The conveying device 11 in the present invention intermittently conveys multiple groups of brake discs 31 to ensure that the brake discs 31 stay at the detection position. The detection mechanism 2 performs direct contact detection, and the bottom surface of the brake disc 31 is supported by the support seat 23. At the same time, the detection contact 24 contacts its top surface, and the distance between the support seat 23 and the detection contact 24 is measured as the thickness value to realize the mechanical measurement principle. Optical detection, optically photographing the brake disc 31 through the detection camera, realizes non-contact thickness detection. Positioning mechanism, driving push rod 3 211 drives connecting member 212 and positioning rod 213 to position the brake disc 31 on the support seat 23 to prevent it from shifting during the detection process.
[0040] Inspection accuracy is improved. The positioning function of the positioning rod 213 reduces the risk of brake disc 31 shifting, thereby reducing inspection errors. Inspection efficiency is optimized. Intermittent conveying, combined with the positioning and inspection mechanism, enables automated batch processing and improves inspection continuity. Flexible inspection methods include direct contact inspection for physical thickness measurement and optical inspection as a non-contact supplement. The combination of the two enhances inspection reliability.
[0041] like Figures 2 to 4 As shown, regarding the basic principle of directly contacting the brake disc 31 to achieve thickness detection, the support seat 23 is supported on the bottom surface of the brake disc 31, and the detection contacts 24 are provided with multiple groups of multiple points that respectively contact the top surface of the brake disc 31. The distance between the support seat 23 and the detection contacts 24 is the thickness of the brake disc 31 at different points.
[0042] like Figure 3 and Figure 5 As shown, multiple groups of detection contacts 24 are adjustably mounted on the fixed base 25 through the contact mounting base 27. The detection mechanism 2 includes a frame 21. The fixed base 25 is mounted on the frame 21 so as to be liftable through the driving push rod 26. The driving push rod 26 is used to drive the lifting and lowering adjustment of the multiple groups of detection contacts 24.
[0043] like Figure 5 and Figure 8 As shown, in order to realize the adjustment of multiple groups of detection contacts 24, the contact mounting seat 27 is slidably installed on the bottom of the fixed seat 25 through the slide rail 29. The fixed seat 25 is also equipped with an adjusting screw 210 for driving the contact mounting seat 27 to move. The detection contacts 24 are mounted on the contact mounting seat 27. Therefore, the adjustment of the contact mounting seat 27 by the adjusting screw 210 is the adjustment of the detection contact 24.
[0044] like Figure 5 and Figure 8As shown, specifically, at least four groups of detection contacts 24 are provided, and the four groups of detection contacts 24 are arranged in a cross-shaped pattern. For different brake discs 31, the four groups of detection contacts 24 can be adjusted to different positions to adapt to contact testing on the surface of the brake disc 31. More specifically, the detection contacts 24 are sensor contacts that detect actual surface conditions by the degree of deformation at their ends. The detection contacts 24 are connected to a control computer via contact wires 28, and the detection contacts 24 transmit detection information to the control computer via the contact wires 28.
[0045] It should be noted that the adjustment screw 210 is merely an exemplary drive method for the detection contact 24. Other drive methods can also be used to achieve displacement drive of the detection contact 24. The adjustment screw 210 can be adjusted in real time via a servo drive. Optionally, during the detection process of a single brake disc 31, real-time adjustment can be used to achieve thickness contact detection at multiple points on the surface of the brake disc 31.
[0046] like Figure 6 As shown, regarding the basic structure of the brake disc 31, the brake disc 31 includes a base plate 32, on which multiple groups of mounting holes 33 are provided, and the driving push rod 3 211 is installed with multiple groups of positioning rods 213 through the connecting piece 212, and the positioning rods 213 correspond to the mounting holes 33.
[0047] like Figure 6 and Figure 7 As shown, regarding the specific method of positioning the brake disc 31 by the positioning rod 213, the positioning rod 213 is provided with a pressure ring 214 with an adjustable position, and the positioning rod 213 is threaded with an adjusting nut 215 for adjusting the position of the pressure ring 214; when the positioning rod 213 is inserted into the mounting hole 33 of the base plate 32, the pressure ring 214 is pressed onto the base plate 32. At this time, the support seat 23 is supported on the bottom of the base plate 32. The simultaneous positioning of the upper and lower parts enables each brake disc 31 to be stably and accurately positioned.
[0048] Specifically, such as Figure 2 and Figure 6 As shown, regarding the specific driving method of the support seat 23, a driving push rod 22 is installed on the frame 21 and at the bottom of the conveying equipment 11, and the support seat 23 is installed on the telescopic rod of the driving push rod 22, and the driving push rod 22 is used to realize the lifting and lowering adjustment of the driving push rod 22.
[0049] like Figure 2 and Figure 4As shown, regarding the inspection camera used to optically photograph the brake disc 31 for thickness detection, an adjustment track 12 is mounted on one side of the conveying device 11. Multiple sets of adjustment seats 13 are slidably mounted on the adjustment track 12. Camera 1 14 is mounted on the adjustment seats 13. Camera 2 15 is mounted on the adjustment seats 13 and on both sides of the conveying path of the brake disc 31. Multiple sets of camera 1 14 and camera 2 15 are provided. Camera 1 14 is used to photograph the top surface of the brake disc 31 to detect surface defects, while camera 2 15 is used to photograph the side of the brake disc 31 to detect its thickness.
[0050] The present invention also has the following comprehensive effects:
[0051] Overall inspection process: Conveyor device 11 intermittently transports multiple sets of brake discs 31, with the conveyor path paused to allow for inspection. Inspection mechanism 2, mounted on conveyor device 11, performs thickness inspection of brake discs 31 during these pauses, combining direct contact and optical methods.
[0052] Direct contact thickness detection: Support base 23 supports the bottom surface of brake disc 31, while multiple sets of detection contacts 24 contact different points on the top surface of brake disc 31. The distance between support base 23 and detection contacts 24 directly reflects the thickness of the corresponding point on brake disc 31. Support base 23 is adjusted by driving push rod 1 22 to adjust to different brake disc 31 heights.
[0053] Optical Thickness and Defect Inspection: The inspection cameras include Camera 1 14 and Camera 2 15, which respectively capture the top surface of the brake disc 31 to detect surface defects and the side surface of the brake disc 31 to perform thickness inspection. Camera 1 14 and Camera 2 15 are mounted on an adjustment base 13, which slides on an adjustment track 12 on one side of the conveyor 11, allowing for position adjustment to accommodate different brake discs 31.
[0054] Positioning mechanism to prevent misalignment: Drive push rod 3 211 is connected to positioning rod 213 via connector 212. Positioning rod 213 is inserted into mounting hole 33 of brake disc 31. The number of positioning rods 213 corresponds to the number of mounting holes 33. An adjustable pressure ring 214 cooperates with an adjusting nut 215. When the positioning rod 213 is inserted into the mounting hole 33, it is pressed against the bottom plate 32 of the brake disc 31, achieving simultaneous positioning of the upper and lower parts and preventing position misalignment during detection.
[0055] The adjustment mechanism provides adaptability and flexibility: the detection contact 24 is mounted on a contact mounting base 27, which slides on the bottom of the fixed base 25 via a slide rail 29. An adjustment screw 210 drives the contact mounting base 27, allowing the position of the detection contact 24 to be adjusted to accommodate different brake disc 31 surfaces. The fixed base 25 is raised and lowered on the frame 21 by driving a push rod 26, allowing the overall height of the detection contact 24 to be adjusted. The adjustment mechanism allows real-time adjustments, enabling multi-point thickness detection during the testing of a single brake disc 31.
[0056] Improved detection accuracy and stability: By simultaneously positioning the upper and lower parts of the positioning rod 213 and the pressure ring 214, the brake disc 31 is prevented from shifting during detection, and the mechanical contact between the support base 23 and the detection contact 24 is combined to reduce measurement errors.
[0057] Highly adaptable and versatile: The position and height of the detection probe 24, as well as the camera position, are adjustable, allowing the device to adapt to brake discs 31 of varying sizes and shapes. Highly efficient: Intermittent conveying allows for automated batch testing; a combination of multi-point thickness detection, direct contact and optical detection for surface defects and side thickness, provides comprehensive inspection capabilities. Operational flexibility and real-time performance: The adjustment mechanism of the detection probe 24 supports real-time adjustments, enabling rapid multi-point measurement within a single brake disc 31 inspection, improving inspection efficiency.
[0058] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
