Description

Technical Field

[0001] This invention relates to the field of brake disc testing technology, and more particularly to an automotive brake disc testing device. Background Technology

[0002] In the field of automated quality inspection of automotive brake discs, existing technical solutions still face significant challenges in meeting integrated requirements such as multi-specification compatibility, dual-sided synchronous inspection, and online cleaning.

[0003] Traditional inspection equipment typically uses rigid fixtures designed for a single size or a limited range of sizes. For brake discs with varying diameters, frequent fixture changes or complex manual adjustments are required, severely limiting inspection efficiency and the flexibility of the production line. Furthermore, most equipment can only inspect one side of the brake disc. To achieve comprehensive inspection of flatness, geometric tolerances, and surface defects (such as cracks) on both sides, manual workpiece flipping or the use of two independent inspection units is often necessary. This not only increases the risk of secondary clamping errors but also results in complex equipment structures, large footprints, and high costs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automotive brake disc testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vehicle brake disc testing device includes a base: Two mounting plates are set on the base for placing the brake disc, and the two mounting plates move alternately on the base; A CCD camera for brake disc surface inspection is mounted on the base, and a leveling instrument for brake disc surface level inspection is rotated and mounted on the mounting plate. A clamping assembly for positioning and adjusting the brake disc is disposed within a placement plate. The clamping assembly includes an adjustment disc rotatably disposed within the placement plate. Multiple clamping rods are slidably disposed at equal angles on the adjustment disc. When the multiple clamping rods slide, they limit and fix the brake disc.

[0006] Preferably, the base is provided with a moving component for driving the two placement plates to move alternately. The moving component includes a support frame slidably disposed on the base and a telescopic frame slidably disposed on the base, and the support frame and the telescopic frame are arranged opposite to each other. The two placement plates are respectively fixedly disposed on the support frame and the telescopic frame. A guide groove is provided on one side of the base. The telescopic frame is slidably disposed in the guide groove, and the telescopic frame can extend and retract according to the shape of the guide groove.

[0007] Preferably, the clamping rod is fitted with a first spring for its reset.

[0008] Preferably, one end of the clamping rod is provided with an incline-shaped flexible friction block.

[0009] Preferably, the placement plate is provided with multiple airbags, and the number of airbags is the same as the number of clamping rods. The multiple airbags are interconnected, and the ends of the clamping rods are fixedly mounted on the airbags.

[0010] Preferably, the placement plate is provided with an air supply component for supplying air to the airbag, and the level detector is provided with a jet box for cleaning the surface of the brake disc. When the air supply component supplies air, part of the airflow enters the airbag to inflate it, and the other part of the airflow enters the jet box for cleaning the brake disc.

[0011] Preferably, the air supply assembly includes a piston portion disposed on the placement plate. The piston portion includes a piston tube, a piston rod, and a piston plate. The piston plate is fixedly disposed at the end of the piston rod, and the piston rod is slidably disposed inside the piston tube. A second spring is sleeved on the piston rod.

The drive assembly includes a drive motor mounted on the placement plate, an electric telescopic rod fixedly mounted at the output end of the drive motor, a cam rotatably mounted on the placement plate, a gear set mounted on one side of the cam, a gear ring rotatably mounted on the placement plate, and the level detector rotatably mounted on the gear ring. The gear ring is connected to the cam via the gear set. A horizontal shaft is provided on the adjustment plate, and the electric telescopic rod is movably engaged with the horizontal shaft and the drive shaft of the cam.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes multiple clamping rods that slide within an adjusting disc to effectively limit and fix brake discs of different sizes and diameters, ensuring ease of use during testing and preventing issues such as insufficient clamping stability caused by varying brake disc diameters. During testing, the automatic rotation of the adjusting disc allows for effective inspection of both sides of the brake disc, ensuring testing quality and improving efficiency. The horizontal leveling instrument, combined with a CCD camera and the alternating movement of two placement plates, creates a streamlined testing process, detecting not only the flatness of both sides of the brake disc but also surface cracks, guaranteeing testing effectiveness. During each test, gas discharged through the air jet box acts on the front of the testing area, ensuring cleanliness and preventing false readings due to impurities on the brake disc surface, further improving testing accuracy.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0018] Reference Figures 1-6 A vehicle brake disc testing device includes a base 1. Two mounting plates 2 are set on the base 1 for placing the brake disc, and the two mounting plates 2 move alternately on the base 1; A CCD camera 3, mounted on base 1, is used for detecting the surface of the brake disc. A leveling instrument 4, which is mounted on the placement plate 2 and is used to detect the horizontality of the brake disc surface, is rotated. A clamping assembly 5 is installed inside the placement plate 2 for positioning and adjusting the brake disc. The clamping assembly 5 includes an adjustment plate 51 that is rotatably installed inside the placement plate 2. Multiple clamping rods 52 are slidably installed on the adjustment plate 51 at equal angles. When the multiple clamping rods 52 slide, they limit and fix the brake disc. refer to Figure 1 The brake disc to be inspected is placed on a mounting plate 2 on the side away from the CCD camera 3. Multiple clamping rods 52 are controlled to slide, bringing their ends closer together, with the brake disc positioned between them. The movement of the clamping rods 52 pushes the brake disc towards the center of the adjusting plate 51. As the clamping rods 52 move, they effectively clamp the brake disc, confining it within the adjusting plate 51. Then, the horizontal detector 4 is rotated to align with the brake disc. When the horizontal detector 4 is perpendicular to the brake disc, it is driven to rotate on the mounting plate 2. At this point, the detection surface of the horizontal detector 4 contacts the surface of the brake disc, effectively inspecting its surface. After one full rotation, one side of the brake disc is inspected. The position of the horizontal detector 4 is adjusted to be parallel to the brake disc again, and then the adjusting plate 51 is driven to rotate, causing it to flip. As the adjusting plate 51 flips, the brake disc inside it also flips simultaneously. After the adjustment disc 51 has flipped, the position of the leveling instrument 4 is adjusted again so that it can inspect the other side of the brake disc to ensure its quality. After the leveling instrument 4 has completed its inspection, it controls the brake disc to move below the CCD camera 3. At this time, the CCD camera 3 can take pictures of the brake disc and detect whether there are cracks or other defects on the surface of the brake disc, thus achieving automatic inspection of the brake disc.

[0019] This invention utilizes multiple clamping rods 52 that slide within an adjusting disc 51 to effectively limit and fix brake discs of different sizes and diameters, ensuring ease of use during testing and preventing issues such as insufficient clamping due to varying brake disc diameters, which could affect clamping stability. During testing, the automatic rotation of the adjusting disc 51 effectively inspects both sides of the brake disc, ensuring testing quality and improving efficiency. The horizontal leveling instrument 4, in conjunction with the CCD camera 3 and the alternating movement of the two placement plates 2, creates a streamlined testing process, detecting not only the flatness of both sides of the brake disc but also surface cracks, ensuring optimal testing results. During each test, the gas discharged through the air jet box 6 acts on the front of the testing position, ensuring cleanliness and preventing false readings due to impurities on the brake disc surface, further improving testing accuracy.

[0020] Preferably, a moving component is provided on the base 1 for driving the two placement plates 2 to move alternately. The moving component includes a support frame slidably disposed on the base 1 and a telescopic frame slidably disposed on the base 1, and the support frame and the telescopic frame are arranged opposite to each other. The two placement plates 2 are respectively fixedly disposed on the support frame and the telescopic frame. A guide groove is provided on one side of the base 1, and the telescopic part of the telescopic frame is slidably disposed in the guide groove. The telescopic frame can extend and retract according to the shape of the guide groove. refer to Figure 1 and Figure 2 The support frame and telescopic frame are driven by an external drive motor. A double Z-shaped slot is provided on the base 1. When the support frame and telescopic frame move relative to each other, the telescopic part of the telescopic frame slides within the slot. When the telescopic frame moves to the smooth section at the bottom of the slot, it shortens, simultaneously lowering the placement plate 2. At this point, the placement plate 2 and the placement plate 2 on the support frame are in an alternating position, thus completing the alternation of the two placement plates 2. When the alternation of the two placement plates 2 is complete, the CCD camera 3 can take a picture of the inspected brake disc. The alternation of the two placement plates 2 enables dual-station inspection during use, effectively improving the inspection efficiency and avoiding waiting during inspection.

[0021] Preferably, a first spring 53 for resetting is sleeved on the clamping rod 52; refer to Figure 6 When the clamping rod 52 slides, the first spring 53 sleeved on the clamping rod 52 is simultaneously compressed or stretched. When the first spring 53 is compressed or stretched, the clamping rod 52 can effectively move linearly along the inner wall of the adjusting plate 51, ensuring the movement stability of the clamping rod 52 and avoiding deviation during use.

[0022] Preferably, one end of the clamping rod 52 is provided with an incline flexible friction block 55; refer to Figure 6 When the ends of the multiple clamping rods 52 approach each other, the brake disc simultaneously approaches the friction block 55. At this time, the friction block 55 can fully fix the brake disc. Since the friction block 55 is flexible, it will not scratch the brake disc during fixing, thus avoiding the problem of damaging the surface of the brake disc due to scratching during testing.

[0023] Preferably, the placement plate 2 is provided with a plurality of airbags 54, and the number of airbags 54 is the same as the number of clamping rods 52. The plurality of airbags 54 are interconnected, and the ends of the clamping rods 52 are fixedly disposed on the airbags 54. refer to Figure 6When the airbag 54 is filled with gas, it gradually inflates. As the airbag 54 inflates, it pushes the clamping rods 52 to slide, bringing their ends closer together. This contact between the clamping rods 52 and the brake disc effectively limits the brake disc's movement, preventing it from wobbling during testing. Furthermore, based on the sliding distance of the clamping rods 52 and the inflation amount of the airbag 54, the clamping rods 52 can limit brake discs of different diameters, preventing situations where the equipment cannot limit movement due to different brake disc sizes.

[0024] Preferably, the placement plate 2 is provided with an air supply assembly 7 for supplying air to the airbag 54, and the level detector 4 is provided with an air jet box 6 for cleaning the surface of the brake disc. When the air supply assembly 7 supplies air, part of the airflow enters the airbag 54 to inflate it, and the other part of the airflow enters the air jet box 6 for cleaning the brake disc. refer to Figure 4 and Figure 6 When the air supply assembly 7 generates airflow, part of the airflow enters the airbag 54, causing the airbag 54 to inflate, thereby pushing the clamping rod 52 to move and effectively limiting the brake disc. Another portion of the gas generated by the air supply assembly 7 enters the jet box 6, and the gas is ejected from the jet box 6 and acts on the brake disc, thoroughly cleaning the surface of the brake disc. This avoids false readings during detection by the leveling instrument 4 and the CCD camera 3, further improving the detection effect of the equipment.

[0025] Preferably, the air supply assembly 7 includes a piston portion 71 disposed on the placement plate 2. The piston portion 71 includes a piston tube, a piston rod, and a piston plate. The piston plate is fixedly disposed at the end of the piston rod, and the piston rod is slidably disposed inside the piston tube. A second spring 73 is sleeved on the piston rod. The piston tube communicates with multiple airbags 54, and an electromagnetic valve is disposed at the communication point. A control valve 72 for airflow control is disposed on the piston tube. refer to Figure 4 When the piston rod pushes the piston plate to move within the piston tube, the gas generated by the downward pressure of the piston plate enters the air bladder 54, causing it to gradually inflate. When the air bladder 54 inflates to the appropriate size, the solenoid valve connected to the air bladder 54 closes, maintaining the inflated effect of the air bladder 54. When the control valve 72 opens, the bottom of the piston tube remains open. At this time, the gas generated by the movement of the piston rod is discharged through the jet box 6, allowing the gas to act on the surface of the brake disc, effectively cleaning the brake disc and ensuring the effectiveness of the inspection.

[0026] Preferably, the placement plate 2 is provided with a drive assembly 8 for driving the adjustment disc 51 to rotate, the level detector 4 to rotate, and the piston rod to move. The drive assembly 8 includes a drive motor 81 mounted on the placement plate 2, and an electric telescopic rod 82 is fixedly mounted on the output end of the drive motor 81. A cam 83 is rotatably mounted on the placement plate 2, and a gear set is provided on one side of the cam 83. A gear ring 84 is rotatably mounted on the placement plate 2, and the level detector 4 is rotatably mounted on the gear ring 84. The gear ring 84 is connected to the cam 83 through the gear set. A horizontal shaft is provided on the adjustment disc 51, and the electric telescopic rod 82 is movably engaged with the horizontal shaft and the drive shaft of the cam 83. refer to Figure 5 After the brake disc is placed, the electric telescopic rod 82 is shortened, engaging with the drive shaft of the cam 83. The electric telescopic rod 82 is then rotated by the drive motor 81, which in turn rotates the cam 83. When the cam 83 rotates, it effectively compresses the piston rod, generating gas within the piston tube. This gas then fully enters the air bladder 54 and the air jet box 6, thereby controlling the clamping rod 52 to limit the brake disc and simultaneously cleaning it. As the cam 83 rotates, the gear set simultaneously drives the gear ring 84, which in turn drives the leveling detector 4. The leveling detector 4 effectively inspects the surface of the brake disc. After the leveling detector 4 has inspected one side of the brake disc, the electric telescopic rod 82 is extended, engaging with the horizontal shaft on the adjusting disc 51. The horizontal shaft is then rotated by the drive motor 81, causing the adjusting disc 51 to flip, thus inspecting the other side of the brake disc and ensuring the effectiveness of the equipment's inspection. The electric telescopic pole 82 is existing technology, and its power source can be an electromagnetic ring, so its extension principle will not be described in detail.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
