Description

Technical Field

[0001] This utility model relates to the field of brake disc processing and testing technology, and in particular to a brake disc processing and testing device with a rotating structure. Background Technology

[0002] As a core component of the automotive braking system, the brake disc's machining precision and surface quality directly determine the safety and stability of the vehicle's braking performance. Therefore, machining and testing equipment is an indispensable key device in the brake disc manufacturing process. This type of equipment is mainly used during and after brake disc machining to fix the brake disc, adjust its angle, and inspect quality indicators such as surface flatness, presence of cracks, scratches, and dimensional deviations, ensuring that every set of brake discs leaving the factory meets industry standards and usage requirements. With the automotive industry's increasing demands for braking system safety and the trend towards high-precision, mass production of brake discs, the market has placed higher demands on the performance of brake disc machining and testing equipment. The equipment not only needs to stably fix the brake disc but also needs to have the ability to accurately adjust the brake disc angle and efficiently complete quality inspections to adapt to the machining and testing needs of different brake disc specifications, ensuring both production efficiency and product quality.

[0003] For example, a Chinese patent for a brake disc processing and testing device (patent publication number CN221078488U) describes a method where a rotating structure on the frame, driven by a motor, rotates a shaft and gears that mesh with the annular toothed grooves on the outer surface of a rotating disc. This allows the rotating disc to drive the testing platform, enabling a CCD camera to scan the entire surface of the brake disc. The fixing structure uses a threaded rod to move a slider and an L-shaped locking block, thus securing the brake disc. However, this patent only addresses the issue of the CCD camera's inability to fully scan the brake disc surface in traditional testing equipment, providing more comprehensive results. It does not optimize the versatility and protection of brake disc fixing, relying on a relatively simple fixing method that is difficult to adapt to various brake disc specifications and is prone to damaging the brake disc. Furthermore, its rotating structure lacks precision in angle adjustment, making it difficult to achieve high-precision angle positioning and failing to meet the demands of high-precision processing and testing. Therefore, this paper proposes a brake disc processing and testing device with a rotating structure to overcome these shortcomings and meet the high-precision processing and testing requirements in brake disc manufacturing.

[0004] Therefore, we propose a brake disc processing and testing device with a rotating structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a brake disc processing and testing device with a rotating structure, which solves the problems of poor brake disc fixation adaptability and low angle adjustment accuracy in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A brake disc processing and testing device with a rotating structure includes a worktable, a fixed frame fixedly mounted on the bottom of the inner wall of the worktable by bolts, a worm gear movably connected to the bottom of the inner wall of the fixed frame, and a rotating shaft extending from the top of the worm gear to the top of the fixed frame. The device also includes: The top rotating shaft of the worm gear is fixedly connected to a brake disc fixing mechanism.

[0007] Preferably, a stepper motor is fixedly installed on one side of the top of the inner wall of the fixed frame, and a worm gear is fixedly connected to one end of the stepper motor's rotating shaft. The worm gear and the worm wheel are meshed together.

[0008] Preferably, the brake disc fixing mechanism includes a cylindrical rotating seat, a fixed hollow column, a slide rail, an arc-shaped support plate, and a damping spring. The top rotating shaft of the worm gear is fixedly connected to the cylindrical rotating seat. A fixed hollow column is fixedly installed at one end of the cylindrical rotating seat near the bottom of its inner wall. Five sets of slide rails are provided on the outer wall of the fixed hollow column near its middle part, and an arc-shaped support plate is slidably connected to one end of each of the five sets of slide rails. Five sets of arc-shaped support plates extend to the top of the cylindrical rotating seat. Two sets of damping springs are fixedly installed on the outer wall of one end of the arc-shaped support plate. The end of the damping spring away from the arc-shaped support plate is fixedly connected to the inner wall of the cylindrical rotating seat.

[0009] Preferably, the brake disc fixing mechanism further includes an arc-shaped stop, a hydraulic telescopic rod, and a top block. Five sets of arc-shaped support plates are respectively fixedly installed with arc-shaped stops on the outer wall near one end of the fixed hollow column. The arc-shaped stops extend to one end of the inner wall of the fixed hollow column. A hydraulic telescopic rod is provided at the bottom of the inner wall of the cylindrical rotating seat. A top block is fixedly connected to the top output end of the hydraulic telescopic rod. The top of the top block extends to one end of the inner wall of the fixed hollow column, and the outer wall of the top block contacts the outer walls of the five sets of arc-shaped blocks respectively.

[0010] Preferably, the top block output end is flat-topped and conical.

[0011] Preferably, a placement plate is fixedly connected to the outer wall of the cylindrical rotating seat near the top end, and the top of the placement plate is flush with the top of the cylindrical rotating seat; Two sets of equally spaced clips are fixedly installed on the outer wall of the five sets of arc-shaped support plates near the top.

[0012] Preferably, a CCD camera is fixedly installed on the top of the inner wall of the workbench, and the CCD camera is located directly above the brake disc fixing mechanism. A CCD display controller is fixedly installed on one side of the workbench.

[0013] This utility model has at least the following beneficial effects: In this device, a hydraulic telescopic rod drives a flat-topped conical block to move upward, pushing an arc-shaped stop block and causing an arc-shaped support plate to slide along a slide rail. Combined with the elastic buffering effect of a damping spring, this forms an elastic clamping structure. On one hand, five sets of arc-shaped support plates, evenly distributed in a ring, can expand or contract synchronously with the thrust of the top block, adapting to brake discs of different inner diameters without requiring fixture replacement, significantly improving the compatibility range and reducing fixture replacement time and cost. On the other hand, the elastic tension of the damping spring ensures that the arc-shaped support plates maintain a moderate clamping force, avoiding damage caused by rigid clamping. Simultaneously, the bottom support of the disc and the axial limiting of the clamping block further ensure the stability of the brake disc fixation, meeting both processing and inspection requirements while protecting the brake disc workpiece from damage.

[0014] This utility model also has the following beneficial effects: This device employs a stepper motor coupled with a worm gear and worm wheel for transmission. The stepper motor itself features high precision and controllable speed, allowing for precise control of rotation angle and speed via a program, avoiding the precision limitations of ordinary motors. Simultaneously, the worm gear and worm wheel transmission offers a stable transmission ratio and minimal backlash, converting the stepper motor's rotation into stable worm wheel rotation, which in turn drives the cylindrical rotating seat and brake disc to rotate synchronously and precisely. No manual calibration is required; the brake disc angle can be adjusted simply by controlling the stepper motor, reducing labor intensity, ensuring precise positioning of the brake disc at different processing and inspection positions, and improving the accuracy and efficiency of processing and inspection.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1-5 A brake disc processing and testing device with a rotating structure includes a worktable 1, a fixed frame 2 fixedly mounted on the bottom inner wall of the worktable 1 by bolts, a worm gear 3 movably connected to the bottom inner wall of the fixed frame 2, and a rotating shaft extending from the top of the worm gear 3 to the top of the fixed frame 2. The device also includes: The top rotating shaft of the worm gear 3 is fixedly connected to a brake disc fixing mechanism.

[0020] Furthermore, a stepper motor 4 is fixedly installed on one side of the top inner wall of the fixed frame 2. A worm gear 5 is fixedly connected to one end of the rotating shaft of the stepper motor 4. The worm gear 5 is meshed with the worm wheel 3. The stepper motor 4 serves as a power source and can precisely control the rotation angle and speed. It drives the worm gear 5 to rotate through the rotating shaft. The worm gear 5 meshes with the worm wheel 3 to transmit the power of the stepper motor 4 to the worm wheel 3, realizing the precise rotation of the worm wheel 3. This, in turn, drives the material tray fixing mechanism and the brake disc to rotate synchronously, meeting the angle adjustment requirements of different processing and inspection positions of the brake disc and ensuring the accuracy of the angle adjustment.

[0021] Furthermore, the brake disc fixing mechanism includes a cylindrical rotating seat 6, a fixed hollow column 7, a slide rail 8, an arc-shaped support plate 9, and a damping spring 10. The top rotating shaft of the worm gear 3 is fixedly connected to the cylindrical rotating seat 6. The fixed hollow column 7 is fixedly installed at one end of the cylindrical rotating seat 6 near the bottom of its inner wall. The outer wall of the fixed hollow column 7 near its middle part is provided with five sets of slide rails 8 distributed in a ring at equal intervals. One end of each of the five sets of slide rails 8 is slidably connected to the arc-shaped support plate 9. The cylindrical rotating seat 6 serves as the main frame of the brake disc fixing mechanism, providing an installation carrier for components such as the fixed hollow column 7 and the arc-shaped support plate 9. At the same time, it rotates synchronously with the worm gear 3, driving the entire brake disc fixing mechanism and the brake disc to rotate. The fixed hollow column 7 provides an installation base for the slide rail 8, ensuring the stability of the slide rail 8. The slide rail 8 provides a sliding guide for the arc-shaped support plate 9, ensuring that the arc-shaped support plate 9 slides smoothly along a preset trajectory, which facilitates the structural guarantee for the arc-shaped support plate 9 to support and fix the brake disc. Five sets of arc-shaped support plates 9 extend to the top of the cylindrical rotating seat 6. Two sets of damping springs 10 are fixedly installed on the outer wall of one end of the arc-shaped support plate 9, and the end of the damping spring 10 away from the arc-shaped support plate 9 is fixedly connected to the inner wall of the cylindrical rotating seat 6. The arc-shaped support plate 9 extends to the top of the cylindrical rotating seat 6 and can directly contact the inner wall of the brake disc to provide inner support for the brake disc. One end of the damping spring 10 is connected to the arc-shaped support plate 9 and the other end is connected to the inner wall of the cylindrical rotating seat 6. When the arc-shaped support plate 9 slides outward to clamp the brake disc, the damping spring 10 is stretched to generate elastic tension, so that the arc-shaped support plate 9 always maintains pressure on the inner wall of the brake disc, realizing stable clamping of the brake disc, while avoiding damage to the brake disc caused by rigid clamping, and can adapt to brake discs with different inner diameters, improving the adaptability of the equipment.

[0022] Furthermore, the brake disc fixing mechanism also includes an arc-shaped stop 11, a hydraulic telescopic rod 12, and a top block 13. Five sets of arc-shaped support plates 9 are respectively fixedly installed with arc-shaped stop 11 on the outer wall near one end of the fixed hollow column 7. The arc-shaped stop 11 extends to one end of the inner wall of the fixed hollow column 7. A hydraulic telescopic rod 12 is provided at the bottom of the inner wall of the cylindrical rotating seat 6. The top output end of the hydraulic telescopic rod 12 is fixedly connected to the top block 13. The arc-shaped stop 11 connects to the arc-shaped support plate 9 and extends to the inner wall of the fixed hollow column 7, and can receive the top block 13. The thrust of block 13 is transmitted to the arc-shaped support plate 9, providing a power transmission medium for the sliding of the arc-shaped support plate 9; the hydraulic telescopic rod 12, as a driving component, can drive the top block 13 to move up and down through extension and retraction, providing stable power for the top block 13 to push the arc-shaped stop block 11; the top block 13 is connected to the output end of the hydraulic telescopic rod 12, which can convert the extension and retraction of the hydraulic telescopic rod 12 into a lateral thrust on the arc-shaped stop block 11, thereby driving the arc-shaped support plate 9 to slide along the slide rail 8, realizing the clamping and releasing control of the brake disc; The top of the top block 13 extends to one end of the inner wall of the fixed hollow column 7, and the outer wall of the top block 13 contacts the outer walls of the five sets of arc-shaped blocks 11 respectively. The top block 13 extends to the inner wall of the fixed hollow column 7 and contacts the five sets of arc-shaped blocks 11, ensuring that the top block 13 can generate a uniform pushing force on the five sets of arc-shaped blocks 11 at the same time when it moves up and down, so that the five sets of arc-shaped support plates 9 slide outward or inward synchronously, ensuring that the brake disc is subjected to uniform force, avoiding brake disc displacement or damage due to uneven force, and improving the stability and symmetry of brake disc fixation.

[0023] Furthermore, the output end of the top block 13 is flat-topped and conical. The flat-topped and conical structure allows the sidewall of the top block 13 to generate a gradually increasing lateral thrust on the arc-shaped stop block 11 when the top block 13 moves upward, so that the arc-shaped support plate 9 can slide outward slowly and smoothly, avoiding sudden increase in thrust that could cause the brake disc to be damaged by sudden force. At the same time, the flat-top design can reduce frictional loss between the top block 13 and the arc-shaped stop block 11, extend the service life of the components, and the conical structure facilitates the smooth separation of the top block 13 from the arc-shaped stop block 11 when the top block 13 moves downward, so that the arc-shaped support plate 9 can be smoothly reset under the action of the damping spring 10.

[0024] Furthermore, a placement plate 14 is fixedly connected to the outer wall of the cylindrical rotating seat 6 near the top. The top of the placement plate 14 is flush with the top of the cylindrical rotating seat 6. The flushness of the placement plate 14 with the top of the cylindrical rotating seat 6 provides a bottom support surface for the brake disc, allowing the brake disc to be placed stably on the placement plate 14 and preventing the brake disc from tilting due to lack of bottom support. At the same time, the placement plate 14 rotates synchronously with the cylindrical rotating seat 6, ensuring that the bottom of the brake disc is always stably supported during rotation, preventing the brake disc from shaking or shifting during processing and testing, and improving the stability of the brake disc during rotation. Two sets of equidistant locking blocks 15 are fixedly installed on the outer wall of the five sets of arc-shaped support plates 9 near the top. The locking blocks 15 are installed on the top outer wall of the arc-shaped support plates 9. When the arc-shaped support plates 9 clamp the inner wall of the brake disc, the locking blocks 15 can be locked at the edge of the brake disc or at a specific slot, restricting the movement of the brake disc in the axial direction and preventing the brake disc from moving upward during rotation or processing and testing. This further enhances the firmness of the brake disc and ensures that the brake disc is always in the preset processing and testing position.

[0025] Furthermore, a CCD camera 16 is fixedly installed on the top of the inner wall of the workbench 1, located directly above the brake disc fixing mechanism. A CCD display controller 17 is fixedly installed on one side of the workbench 1. The CCD camera 16, located directly above the brake disc fixing mechanism, can clearly capture the processing condition of the brake disc surface, including whether there are scratches, cracks, dimensional deviations, and other defects, providing image data for brake disc quality inspection. The CCD display controller 17 receives the image signals transmitted by the CCD camera 16, processes and analyzes the images, and displays them in real time, allowing staff to intuitively observe the processing quality of the brake disc, quickly determine whether the brake disc meets the standards, and improve inspection efficiency and accuracy.

[0026] In summary: First, the hydraulic telescopic rod 12, in conjunction with the top block 13 and the arc-shaped stop block 11, achieves initial positioning and support for the brake disc. When it is necessary to fix the brake disc, the equipment activates the hydraulic telescopic rod 12, and its top output end pushes the top block 13 upward. Since the output end of the top block 13 is flat-topped and conical, and the outer wall of the top block 13 is in contact with the outer walls of the five sets of arc-shaped stop blocks 11, as the top block 13 moves upward, the flat-topped conical structure will generate an outward pushing force on the arc-shaped stop blocks 11. The five sets of arc-shaped stop blocks 11 are respectively fixed on the outer wall of the five sets of arc-shaped support plates 9 near the fixed hollow column 7. Under the action of the pushing force, the arc-shaped stop blocks 11 drive the arc-shaped support plates 9 to slide outward along the slide rail 8 on the outer wall of the fixed hollow column 7, so that the five sets of arc-shaped support plates 9 gradually unfold until they contact the inner wall of the brake disc, initially achieving support and positioning for the brake disc, preparing for subsequent fixing. Then, the brake disc is stably clamped by the damping spring 10 linked to the arc-shaped support plates 9. As the arc-shaped support plate 9 slides outward along the slide rail 8, the damping spring 10 fixed to the outer wall of one end of the arc-shaped support plate 9 will be stretched. The damping spring 10 has elastic buffering characteristics. When the arc-shaped support plate 9 contacts the inner wall of the brake disc, the elastic tension of the damping spring 10 will ensure that the arc-shaped support plate 9 always maintains pressure on the inner wall of the brake disc, thereby stably clamping the brake disc. This elastic clamping method can avoid damage to the brake disc caused by rigid clamping, and can also adapt to brake discs with different inner diameters, improving the equipment's adaptability to brake discs and ensuring that the brake disc will not loosen or shift during subsequent processing and testing. Meanwhile, a placement plate 14, fixed to the outer wall near the top of the cylindrical rotating seat 6, has its top flush with the top of the cylindrical rotating seat 6. The brake disc is placed on the placement plate 14, which provides bottom support for the brake disc, further enhancing the stability of the brake disc after fixing. Furthermore, a locking block 15 on the outer wall near the top of the arc-shaped support plate 9 can lock onto the edge of the brake disc, preventing it from moving axially and further improving the fixing effect. Then, the stepper motor 4, in conjunction with the worm gear 5 and worm wheel 3, achieves precise rotation adjustment of the brake disc. When the angle of the brake disc needs to be adjusted to meet the processing and testing requirements of different positions, the equipment starts the stepper motor 4 on one side of the top of the inner wall of the fixing frame 2. The rotating shaft at one end of the stepper motor 4 drives the worm gear 5 to rotate. Since the worm gear 5 meshes with the worm wheel 3, which is movably connected to the bottom of the inner wall of the fixing frame 2, the rotation of the worm gear 5 drives the worm wheel 3 to rotate. The rotating shaft at the top of the worm wheel 3 extends to the top of the fixing frame 2 and is fixedly connected to the cylindrical rotating seat 6. Therefore, the rotation of the worm wheel 3 drives the cylindrical rotating seat 6 to rotate synchronously. The brake disc is fixed between the arc-shaped support plate 9 and the placement plate 14 on the cylindrical rotating seat 6, thereby driving the brake disc to rotate together.The stepper motor 4 features high precision and controllable speed. By controlling its own rotation angle and speed, it precisely adjusts the rotation of the worm gear 5. Through the meshing transmission between the worm wheel 3 and the worm gear 5, it achieves precise control over the rotation angle and speed of the brake disc, ensuring the brake disc remains at the required processing and inspection position. Finally, the CCD camera 16, in conjunction with the CCD display controller 17, achieves visual inspection of the brake disc's processing quality. Once the brake disc rotates to the inspection position driven by the stepper motor 4, the CCD camera 16, fixed to the top of the inner wall of the worktable 1, begins operation. Located directly above the brake disc fixing mechanism, the CCD camera 16 clearly captures the processing condition of the brake disc surface, including the presence of scratches, cracks, dimensional deviations, and other defects. The CCD camera 16 transmits the captured image signal to the CCD display controller 17 on one side of the worktable 1. The CCD display controller 17 processes, analyzes, and displays the image signal, allowing operators to visually observe the processing quality of the brake disc and determine whether it meets processing standards. If it is necessary to inspect different positions of the brake disc, the brake disc can be rotated again by the stepper motor 4 to adjust to the new inspection position. The CCD camera 16 repeats the above shooting and inspection process to achieve all-round inspection of the processing quality of the brake disc.
