Description

Technical Field

[0001] This utility model belongs to the field of brake disc processing technology, and specifically relates to a flip-up fixture structure for polishing and grinding brake discs. Background Technology

[0002] In a vehicle braking system, the brake disc is one of the core components. Brake calipers clamp the brake disc to generate braking force, enabling the vehicle to decelerate or stop. Its braking performance directly affects vehicle safety, therefore, strict requirements are placed on the machining precision of the brake disc. The production and machining process of brake discs involves multiple steps, including grinding, polishing, and drilling. The successful execution of these steps relies on the stable positioning of the brake disc by the tooling fixture. Only by precisely fixing the brake disc with a fixture can the machining tools be prevented from shifting due to brake disc displacement during operation, thus ensuring the machining quality of the brake disc.

[0003] However, most brake disc mounting fixtures on the market currently suffer from limited functionality. Most fixtures can only accommodate a single machining process, such as grinding or drilling positioning, and cannot simultaneously support multiple operations like grinding, polishing, and drilling. This necessitates frequent fixture changes or transitions between different processes during the complete brake disc manufacturing process. This not only increases operational steps and time costs but can also lead to cumulative errors from multiple positioning operations, significantly reducing overall production efficiency and making it difficult to meet the demands of large-scale production.

[0004] To address the aforementioned issues, targeted improvements have been attempted in related technical fields. For example, Chinese Patent No. CN221658992U discloses a fixing fixture for brake disc processing. This fixture includes a base, a transverse positioning mechanism mounted on the top of the base, a positioning shaft rotatably mounted at the center of the top of the base, several sets of arc-shaped plates slidably mounted on the side wall of the positioning shaft, and several sets of support seats on the periphery. It allows the brake disc to be inserted through the positioning shaft, supported by the support seats, longitudinally positioned using a rotary clamping cylinder, and laterally positioned by the arc-shaped plates. Simultaneously, rotating the positioning shaft can drive the brake disc to rotate synchronously, thus adapting to various processing steps such as grinding, polishing, or drilling, reducing sequential operations, and improving production efficiency to a certain extent.

[0005] However, the clamp disclosed in this patent still has significant shortcomings in practical applications. The core problem lies in the lack of a flip-over adjustment function. When machining brake discs, it cannot flexibly flip the clamped brake disc according to processing requirements. Obviously, when processing both sides of the brake disc is required, the brake disc must first be disassembled, its direction adjusted, and then repositioned and installed. Quick flip-over adjustment is not possible, which not only increases operational complexity but may also affect processing accuracy due to secondary positioning. Furthermore, the clamp can only rotate the brake disc in a single direction, failing to achieve multi-angle rotation adjustment. This makes it difficult to cover all processed surfaces of the brake disc during processes requiring multi-directional machining, such as full polishing, resulting in blind spots and affecting the uniformity and integrity of the processing effect. Therefore, the existing technology has certain defects and deficiencies, necessitating improved design. Utility Model Content

[0006] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a flip-up fixture structure for polishing and grinding brake discs, so as to solve the problems raised in the background art.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A flip-up clamping structure for polishing and grinding brake discs includes a frame, a telescopic module is fixedly installed on the outer side of the frame, and a clamping module is fixedly installed on the movable end of the telescopic module.

[0009] The telescopic module includes a first electric push rod and a sliding shaft. The first electric push rod is fixedly installed at one end of the bottom of the frame. The sliding shaft is slidably connected to the side of the frame away from the first electric push rod. A side seat is fixedly installed at the top output end of the first electric push rod. A side seat is also fixedly installed at the top of the sliding shaft. The clamping module is fixedly installed on the top of the side seat.

[0010] As a preferred technical solution, the clamping module includes a second electric push rod, which is fixedly installed on the upper end of the side seat. The output end of the second electric push rod passes through the side seat. The output end of one second electric push rod is rotatably connected to a turntable, and the output end of the other second electric push rod is fixedly installed with a first motor. The output end of the first motor and the inner side of the turntable are both fixedly installed with clamping mechanisms.

[0011] As a preferred technical solution, the clamping mechanism includes a clamping frame, the clamping frame having a V-shaped overall top view, a bearing plate fixedly connected to the lower inner side of the clamping frame, the bearing plate also having a V-shaped top view, a driving component inside the clamping frame, a positioning component fixedly connected to the top of the clamping frame, and a centering correction weight ball fixedly connected to the bottom of the clamping frame on the side away from the first motor.

[0012] As a preferred technical solution, the driving component includes a square groove, which is opened on both sides inside the clamping frame. Adjustable guide rollers are rotatably connected inside the square groove in a linear arrangement with equal spacing. A second motor is fixedly installed on the top side of the clamping frame near the first motor in a linear arrangement with equal spacing. The output end of the second motor is fixedly connected to the top of the bottom adjusting guide roller.

[0013] As a preferred technical solution, the top of the bearing plate is rotatably connected with lower ball bearings at equal intervals, and the combined cross-sectional shape of the bearing plate and the clamping frame is L-shaped.

[0016] In summary, the present invention has the following main advantages:

[0017] First, during the application of this technical solution, by setting up a drive mechanism with adjustable guide rollers and dual motors, the brake disc can be driven to rotate stably in all directions during use, adapting to the grinding needs of different polishing positions. It can also adjust the rotation state of the brake disc at any time according to the processing angle, thereby achieving the effect of eliminating processing blind spots and realizing comprehensive processing. This solves the problem in the existing technology that the fixture cannot flexibly adjust the rotation of the brake disc, resulting in blind spots in processing and difficulty in achieving comprehensive polishing.

[0018] Secondly, during the application of this technical solution, by setting up a clamping module that can be linked to lift and flip, the brake disc can be lifted first and then flexibly flipped by motor drive during use. Double-sided processing does not require disassembly and repositioning, avoiding secondary positioning errors. This simplifies the double-sided processing process and improves processing efficiency and accuracy. It solves the problem in the prior art that the clamp cannot flexibly flip the brake disc, which leads to frequent sequence changes, cumbersome operation and easy positioning errors in double-sided processing.

[0024] Example

[0025] refer to Figures 1 to 4 The present embodiment of a reversible clamping structure for polishing and grinding brake discs includes a frame 1, a telescopic module 3 fixedly installed on the outer side of the frame 1, and a clamping module 2 fixedly installed on the movable end of the telescopic module 3.

[0026] The telescopic module 3 includes a first electric push rod 31 and a sliding shaft 32. The first electric push rod 31 is fixedly installed at one bottom end of the machine frame 1. The sliding shaft 32 is slidably connected to the side of the machine frame 1 away from the first electric push rod 31. A side seat 33 is fixedly installed at the top output end of the first electric push rod 31. A side seat 33 is also fixedly installed at the top end of the sliding shaft 32. The clamping module 2 is fixedly installed on the top of the side seat 33. During the application of this device, by setting up the machine frame 1, the telescopic module 3, and the clamping module 2, and the telescopic module 3 including the first electric push rod 31, the sliding shaft 32, and the side seat 33, the machine frame 1 provides an installation base for the telescopic module 3 and the clamping module 2 during use. First, the first electric push rod 31 is started according to the size of the brake disc to be processed. The first electric push rod 31 drives the top side seat 33 to move up and down. At the same time, the sliding shaft 32 slides synchronously on one side of the machine frame 1, driving the corresponding side seat 33 to move accordingly. The height of the seat 33 is adjusted synchronously, thereby driving the clamping module 2 at the top to be stably adjusted to the height position suitable for the brake disc. Once the height of the clamping module 2 is determined, the brake disc can be fixed by the clamping module 2. If it is necessary to adjust the relative height between the brake disc and the processing equipment during subsequent processing, the first electric push rod 31 can be activated again. With the synchronous sliding of the sliding shaft 32, the clamping module 2 can be raised and lowered smoothly. Its beneficial effect is that the cooperation between the first electric push rod 31 and the sliding shaft 32 makes the height adjustment of the clamping module 2 more stable, avoiding tilting during the adjustment process and causing the brake disc positioning deviation. At the same time, it can flexibly adapt to brake discs of different thicknesses and sizes. It can meet the processing needs of various specifications of brake discs without changing the fixture. It solves the problems of fixed height of some fixtures in the existing technology, which can only adapt to a single specification of brake disc, and the time and effort required to change the fixture. It improves the versatility and processing efficiency of the equipment.

[0027] refer to Figures 1-4The clamping module 2 includes a second electric push rod 21, which is fixedly installed on the upper end of the side seat 33. The output end of the second electric push rod 21 passes through the side seat 33. The output end of one second electric push rod 21 is rotatably connected to a turntable 22, and the output end of the other second electric push rod 21 is fixedly installed with a first motor 23. A clamping mechanism 24 is fixedly installed on both the output end of the first motor 23 and the inner side of the turntable 22. The clamping mechanism 24 includes a clamping frame 241, which is V-shaped when viewed from above. A bearing plate 242 is fixedly connected to the lower inner side of the clamping frame 241. The support plate 242 is also V-shaped when viewed from above. The clamping frame 241 houses a drive assembly 243. A positioning assembly 244 is fixedly connected to the top of the clamping frame 241. A centering and corrective load-bearing ball 245 is fixedly connected to the bottom of the clamping frame 241 on the side furthest from the first motor 23. During application, this device, by setting up the clamping module 2 containing the second electric push rod 21, turntable 22, and first motor 23, and the V-shaped clamping frame 241 with the support plate 242, drive assembly 243, positioning assembly 244, and centering and corrective load-bearing ball 245, ensures that... First, the centering and correcting weight ball 245 is used to maintain the balance of the clamping frame 241 on the side away from the first motor 23. The brake disc is placed on the V-shaped support plate 242 of the two clamping frames 241. The support plate 242 automatically centers the brake disc laterally. The second electric push rod 21 is activated to push the two clamping frames 241 closer together, so that the inner side of the clamping frame 241 fits against the edge of the brake disc. Then, the positioning component 244 fixes the brake disc longitudinally, completing the clamping. During processing, the drive component 243 drives the brake disc to rotate. When the brake disc needs to be flipped, the first motor 23 is activated to drive the one-side clamping mechanism 24 to rotate, and the other side clamps... Mechanism 24 rotates synchronously with turntable 22 to achieve brake disc flipping. Its beneficial effects are that the V-shaped clamping frame 241 and the bearing plate 242 are adapted to brake discs of different sizes, and the centering and correcting load ball 245 improves clamping stability. There is no need for repeated manual calibration, and the positioning efficiency is higher. The first motor 23 works with turntable 22 to achieve flexible brake disc flipping without disassembly and repositioning, reducing secondary positioning errors. At the same time, the drive component 243 drives the brake disc to rotate, which facilitates comprehensive processing. This solves the problems of poor clamping adaptability, cumbersome positioning, and low processing efficiency caused by the inability to flexibly flip the brake disc in the prior art.

[0028] refer to Figures 3-4The drive assembly 243 includes a square groove 2431, which is formed on both sides inside the clamping frame 241. Adjustable guide rollers 2432 are rotatably connected to the inside of the square groove 2431 in a linear arrangement with equal spacing. A second motor 2433 is fixedly installed on one side of the top of the clamping frame 241 near the first motor 23, with equal spacing and linear arrangement. The output end of the second motor 2433 is fixedly connected to the top of the bottom adjusting guide rollers 2432. Lower ball bearings 2434 are rotatably connected to the top of the support plate 242 at equal spacing. The support plate 242 and... The clamping frame 241 has an L-shaped cross-section. During application, the device is equipped with a drive assembly 243 containing a square groove 2431, an adjusting guide roller 2432, and a second motor 2433, as well as a support plate 242 with lower ball bearings 2434 that is L-shaped with the clamping frame 241. This allows the second motor 2433, located near the first motor 23, to be activated when the brake disc is fixed to the support plate 242 by the clamping frame 241. The second motor 2433 then drives the adjusting guide roller 2432 within the square groove 2431 to rotate. After the adjusting guide roller 2432 contacts the edge of the brake disc, it drives the brake disc to rotate synchronously on the support plate 242. Simultaneously, the lower ball bearings 2434 on the top of the support plate 242 roll along with the brake disc, reducing the frictional resistance between the brake disc and the support plate 242 and ensuring smooth rotation of the brake disc. The L-shaped combination structure of the clamping frame 241 and the support plate 242 provides stable support for the brake disc from the side and bottom, preventing deviation or wobbling during brake disc rotation. Its beneficial effect lies in the fact that the adjusting guide roller 2432, in conjunction with the second motor 243... The 3-drive system allows for flexible control of the brake disc's rotation, adapting to different polishing and grinding speed requirements, facilitating comprehensive processing of all parts of the brake disc. The 2434 lower ball bearings reduce rotational resistance, minimizing damage to the brake disc surface caused by friction and improving processing quality. The L-shaped combination structure enhances the support stability of the brake disc, solving the problems of jamming and unstable positioning when some fixtures drive the brake disc in existing technologies, resulting in low processing efficiency and poor finished product quality. This further improves the convenience and precision of brake disc polishing and grinding.

[0029] refer to Figures 3-4The positioning component 244 includes a fixing block 2441, which is fixedly connected to the middle of the top outer side of the clamping frame 241. A fixing arm 2442 is fixedly installed on the top of the fixing block 2441. A third electric push rod 2443 is fixedly installed on the outer end of the fixing arm 2442. A top pressure plate 2444 is fixedly installed through the fixing arm 2442 at the output end of the third electric push rod 2443. An upper ball bearing 2445 is rotatably connected to the bottom of the top pressure plate 2444 at equal intervals. Support legs 4 are fixedly installed at the four corners of the bottom of the frame 1. The bottom of the support legs 4 is fixedly installed with... There is a mounting plate 5, and mounting holes 6 are provided at each of the four corners of the mounting plate 5. The mounting holes 6 are all countersunk holes. During the application of this device, it is equipped with a positioning assembly 244 containing a fixing block 2441, a fixing arm 2442, a third electric push rod 2443, a top pressure plate 2444 and an upper ball bearing 2445, as well as support legs 4 with mounting plates 5 and countersunk mounting holes 6. When in use, the device is first fixed in a preset position on the processing site by means of the mounting plate 5 at the bottom of the support legs 4 and the countersunk mounting holes 6 at the four corners. The countersunk design prevents the fixing bolts from protruding and avoids them from interfering with surrounding components. Interference is prevented, and the support leg 4 keeps the device at a distance from the ground, reducing the impact of ground debris on internal components. After the brake disc is placed on the support plate 242 of the clamping frame 241, the third electric push rod 2443 of the positioning assembly 244 is activated. The third electric push rod 2443 pushes the top pressure plate 2444 downward. The upper ball bearings 2445 at the bottom of the top pressure plate 2444 contact the upper surface of the brake disc and apply pressure, thus fixing the brake disc longitudinally in conjunction with the support plate 242. When the brake disc rotates subsequently, the upper ball bearings 2445 roll synchronously with it, reducing frictional resistance, which has beneficial effects. The result is that the countersunk mounting hole 6 and the support leg 4 make the device stable and do not interfere with the surrounding equipment, solving the problem of interference caused by protruding bolts after the existing device is installed; the positioning component 244, through the cooperation of the upper ball 2445 and the third electric push rod 2443, can not only achieve stable longitudinal fixation of the brake disc, but also reduce friction during rotation and avoid damage to the surface of the brake disc. At the same time, it eliminates the need for manual tightening, reducing the intensity of operation, solving the problems of unstable longitudinal positioning and cumbersome manual operation of the existing fixture, and further improving the stability and convenience of brake disc processing.

[0030] During the application of this device, for the electric actuators, the DTZ300 series (24VDC, 300N thrust, 50-200mm stroke) or LAM25 series (380VAC, 1000N thrust, 100-300mm stroke) are compatible, selected according to the brake disc size and load; the first motor 23 is a 60BLDC brushless DC motor (24VDC, 400W power, 1500rpm speed, with a 1024-line encoder and BLD-60 driver) used to drive the brake disc to rotate and flip; the second motor 2433 is a 42-stepper motor without a brake mechanism (12VDC, 50W power, 1.8° step angle, with DM420 driver). Because it has no electromagnetic brake or mechanical braking components, the output shaft has no locking force after power failure and can rotate freely; the control core is a Siemens S7-1200 series PLC (CPU1214CDC / DC / DC), paired with TZ- The 3112 limit switch (250VAC, 5A) provides overtravel protection. The power supply module uses a Mean Well RD-120-24 (output 24VDC / 5A) to power the PLC, brushless motor, and electric actuator. The Mean Well RS-50-12 (output 12VDC / 4.2A) separately powers the stepper motor and driver. The main power supply circuit is connected to 380VAC three-phase power and a three-phase leakage current protector is connected in series. After branching, one circuit directly powers the 380VAC electric actuator, and the other circuit is converted to low voltage power by the power supply module. The PLC receives limit switch and button signals through the input circuit, and the output circuit is connected to the contactor coil and motor driver to control the start and stop of the electric actuator and the speed and direction of the motor. The first motor 23 driver receives analog signals from the PLC to achieve closed-loop control, and the second motor 2433 driver adjusts the speed through PLC pulse signals to ensure that the output shaft can rotate freely after power failure while ensuring the coordinated operation of all components.

[0031] Operating principle and advantages: Before using this device, first fix it in the preset position at the processing site through the countersunk mounting holes 6 on the mounting plate 5 on the bottom support leg 4 of the frame 1. The support leg 4 can keep the device at a certain distance from the ground to prevent ground debris from affecting the operation of internal components. The frame 1 provides a stable mounting frame for the telescopic module 3 and the clamping module 2. Then, according to the size of the brake disc to be processed, start the first electric push rod 31 of the telescopic module 3. The first electric push rod 31 drives the top side seat 33 to move up and down, and the sliding shaft 32 slides synchronously on the side of the frame 1 to ensure that the clamping module 2 can be stably adjusted in height until the bearing plate 242 of the clamping mechanism 24 is reached. The device adapts to the clamping position of the brake disc. During use, when the brake disc is not clamped, the centering and correcting load shaft at the bottom of the clamping frame 241 on the side away from the first motor 23 will use its own weight to keep the clamping frame 241 on that side stable and balanced, preparing for the subsequent placement of the brake disc. This allows the brake disc to quickly be in a parallel and centered initial position after placement. During this process, the countersunk mounting holes 6 of the mounting plate 5 can prevent the fixing bolts from protruding and avoid interference with other components. The height adjustment function of the telescopic module 3 allows the device to adapt to brake discs of different sizes, solving the problem of poor compatibility of existing clamps and the inability to fix only a single size of brake disc, and reducing the time wasted due to changing clamps.

[0032] The brake disc is placed on the V-shaped support plate 242 of the clamping mechanisms 24 on both sides. Relying on the balance state pre-maintained by the centering correction load shaft, and combined with the automatic lateral centering effect of the V-shaped structure of the support plate 242, the brake disc can be directly in a parallel and centered position, avoiding positioning deviation due to center of gravity shift. Then, the second electric push rod 21 of the clamping module 2 is activated to push the clamping mechanisms 24 on both sides closer to the brake disc until the inner side of the clamping frame 241 is in close contact with the edge of the brake disc. Then, the third electric push rod 2443 of the positioning component 244 is activated to push the top pressure plate 2444 downward, and the bottom of the top pressure plate 2444 rolls upward. The ball 2445 contacts and applies pressure to the upper surface of the brake disc, and together with the lower ball 2434 on the top of the support plate 242, the brake disc is firmly fixed in the longitudinal and transverse directions. At this time, the brake disc is fixed by pushing the top pressure plate 2444 downward by the third electric push rod 2443. The design of the V-shaped clamping frame 241 can stably clamp and adapt to brake discs of different sizes. The bidirectional positioning of the positioning component 244 further improves the clamping stability and solves the problem of brake disc displacement during processing caused by unstable clamping in existing fixtures. This creates conditions for subsequent precise processing and eliminates the need for repeated manual calibration, effectively improving positioning efficiency.

[0033] During processing, the second motor 2433 on top of the adjusting guide roller 2432, which is in contact with the brake disc, can be started first. The second motor 2433 drives the adjusting guide roller 2432 in the square groove 2431 to rotate. Then, the first motor 23 is started, which drives the clamping mechanism 24 on one side to rotate. With the synergistic effect of the upper ball bearing 2445, the lower ball bearing 2434, and the adjusting guide roller 2432, the clamping mechanism 24 can drive the brake disc to rotate synchronously through the rotating adjusting guide roller 2432. The upper ball bearing 2445 and the lower ball bearing 2434 will roll synchronously with the brake disc, reducing frictional resistance. At this time, the processing equipment can polish the exposed surface of the brake disc to ensure stable rotation of the brake disc and achieve full polishing. When the brake disc needs to be flipped after one side of the processing is completed, the second electric push rod 21 is started first to drive the clamped brake disc to move upward. After the brake disc is lifted, the first motor 23 is started. The first motor 23 rotates in the opposite direction, causing the brake disc to flip to a downward position. The clamping mechanism 24 on the other side rotates synchronously with the turntable 22. After the flip is completed, the second electric push rod 21 is controlled to drive the brake disc back down. The third electric push rod 2443 is activated again to push the top pressure plate 2444 to press the brake disc, so that the other side of the brake disc can be processed. This device achieves flexible adjustment of the rotation and flipping of the brake disc by adjusting the guide roller 2432 in coordination with the second motor 2433 and the first motor 23. It does not require disassembling the brake disc for repositioning, which solves the problem that the existing fixtures cannot be flipped and that double-sided processing requires frequent sequence changes in the background technology. It avoids the error caused by secondary positioning and shortens the processing cycle. At the same time, the brake disc can rotate in all directions under the drive of the adjusting guide roller 2432, eliminating the processing blind spots of the existing fixtures and improving the uniformity of the brake disc processing quality.

[0034] During processing, if the rotation state of the brake disc needs to be adjusted, the second motor 2433 at the corresponding position can be started and stopped, and the brake disc can be driven to change its rotation state by adjusting the guide roller 2432. At the same time, the rotation speed of the brake disc can be controlled by adjusting the speed of the second motor 2433 to adapt to different polishing and grinding requirements. If a specific angle edge of the brake disc needs to be processed, simply start the first motor 23 to make the brake disc adjust and stop at the target angle. After processing is completed, all motors are turned off. First, the third electric push rod 2443 is started to retract the top pressure plate 2444, then the second electric push rod 21 is started to drive the clamping mechanism 24 away from the brake disc, and finally the first... The electric push rod 31 drives the clamping module 2 to move downwards, making it convenient for operators to remove the processed brake disc. All components are automatically controlled by the electric push rod and motor, reducing the intensity of manual operation. Moreover, the clamping mechanism 24, drive component 243 and other components adopt a modular design. When a component is damaged, there is no need to disassemble the entire device. Only the corresponding module needs to be replaced, which reduces the difficulty and cost of maintenance. Compared with the problems of complex operation and cumbersome maintenance of existing fixtures, this device greatly improves the convenience of operation and maintenance efficiency. At the same time, it can accommodate various processing needs such as polishing and grinding without replacing equipment, further improving production efficiency and meeting the needs of large-scale production.

Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
