Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle parts processing equipment, specifically a grinding device for processing electric vehicle brake pads. Background Technology

[0002] In the field of electric vehicle brake pad processing, the quality of brake pad grinding is directly related to the performance of the braking system and driving safety. Efficient and precise grinding equipment is the core equipment to ensure the processing accuracy of brake pads. Currently, traditional grinding equipment has obvious deficiencies in terms of the adaptability of grinding components and processing flexibility, making it difficult to meet diverse and high-quality processing needs.

[0003] On the one hand, the grinding components of existing grinding devices are mostly integral fixed structures. When the grinding disc wears out due to long-term use, or when it is necessary to replace the grinding disc with a suitable one for different brake pad specifications, the disassembly and assembly process is cumbersome, requires professional tools, and consumes a lot of time, affecting processing efficiency. Moreover, the traditional fixed connection method is prone to loosening and inaccurate positioning after frequent disassembly and assembly, resulting in a decrease in grinding accuracy and an inability to reliably guarantee the grinding quality of brake pads. On the other hand, the structure of electric vehicle brake pads is complex, and different areas need to be ground specifically. The position adjustment of the grinding components of existing devices is inconvenient and it is difficult to flexibly adapt to the grinding of different areas of the brake pads. Faced with the processing needs of multiple areas, it is necessary to adjust the position of the workpiece or change the grinding tools multiple times, increasing the processing steps and time, and reducing production efficiency.

[0004] Therefore, developing a grinding device with detachable and easily replaceable grinding components and flexible adjustment to grind different areas of the brake pads is key to improving the processing efficiency and quality of electric vehicle brake pads, and is of great significance for optimizing the brake pad processing flow and enhancing the practicality of the equipment.

[0010] Preferably, the adjusting assembly includes a fixed sleeve fixedly connected to the bottom of the cross bracket, a rotating shaft rotatably connected to the bottom of the cross bracket and inside the fixed sleeve, a gear fixedly connected to the outer wall of the rotating shaft, and two upper racks and two lower racks adapted to the gears at the bottom of the cross bracket, with the two upper racks and two lower racks respectively meshing with the gears.

[0011] Preferably, the outer wall of the fixed sleeve is provided with a plurality of rectangular through holes, one end of each of the two upper racks and the two lower racks passes through the rectangular through holes and extends to the outside of the fixed sleeve and is fixedly connected to the side walls of the plurality of movable columns one by one, and the two upper racks and the two lower racks are slidably connected to the fixed sleeve.

[0016] (2) This device achieves flexible and adaptable grinding of different areas of the brake pad by adjusting the components and driving the components. Rotating the knob drives the gear and rack to mesh, so that the moving column slides along the slide to adjust the position of the grinding pad. At the same time, the hydraulic rod drives the lifting and the motor drives the rotation. On the one hand, the position of the grinding pad can be precisely adjusted according to the grinding requirements of different areas of the brake pad. There is no need to adjust the workpiece or change the tool multiple times. Multiple areas can be ground in one clamping, reducing the processing steps and saving time and cost. On the other hand, the stable power provided by the driving component and the precise control of the adjusting component ensure the uniformity and consistency of grinding of each area of ​​the brake pad, improve the overall processing quality, enhance the adaptability of the device to complex brake pad structures, and improve the flexibility and applicability of production.

[0024] Example:

[0025] Please see Figures 1-5This utility model discloses a grinding device for processing electric vehicle brake pads, including a device body 1. The device body 1 includes a base 101, and a fixed bracket 102 is fixedly connected to the top of the base 101. A detachable grinding component 2 is provided inside the fixed bracket 102. The detachable grinding component 2 includes a cross bracket 201. Multiple sliding grooves are opened at the bottom of the cross bracket 201.

With the drive component 3 providing power, the adjustment component 4 adjusting the position, and the replacement component 5 assisting in the operation, the grinding disc can be quickly replaced and operated stably. At the same time, it can be flexibly adjusted to adapt to the area of ​​brake pad grinding, improving processing efficiency and accuracy.

[0026] As one implementation method of this embodiment, such as Figure 1 As shown, the drive assembly 3 includes a lifting plate 301 slidably connected to the inner side wall of the fixed bracket 102. The bottom of the lifting plate 301 is fixedly connected to the lifting bracket 302. The top of the lifting bracket 302 is fixedly connected to the top of the inside of the lifting bracket 302. The output end of the first drive motor 303 passes through the lifting bracket 302 and extends to its outer side and is fixedly connected to the top of the cross bracket 201. The drive assembly 3 supports the sliding of the lifting plate 301 through the inner side wall of the fixed bracket 102. The lifting plate 301 drives the bottom lifting bracket 302 to move synchronously. Power is output by the first drive motor 303 inside the lifting bracket 302. Its output end passes through the lifting bracket 302 and is connected to the top of the cross bracket 201, realizing the rotation drive and lifting adjustment of the cross bracket 201 and the grinding assembly. It provides stable rotation power for grinding operations and can flexibly adjust the grinding height to adapt to brake pads of different thicknesses, ensuring the controllability and precision of the grinding process.

[0027] As one implementation method of this embodiment, such as Figure 1 As shown, a hydraulic rod 304 is fixedly connected to the top of the fixed bracket 102. The output end of the hydraulic rod 304 passes through the fixed bracket 102 and extends into it, and is fixedly connected to the top of the lifting plate 301. The hydraulic rod 304 at the top of the fixed bracket 102 provides driving force, and its output end passes through the fixed bracket 102 and is connected to the top of the lifting plate 301, causing the lifting plate 301 to slide along the inner wall of the fixed bracket 102, thereby realizing the stable lifting and lowering of the lifting bracket 302 and the grinding components below. It can accurately control the pressure and distance between the grinding disc 203 and the brake pad, adapt to the grinding needs of workpieces of different thicknesses, and improve the stability and adjustment accuracy of the grinding process.

[0028] As one implementation method of this embodiment, such as Figure 4 As shown, the adjusting assembly 4 includes a fixed sleeve 401 fixedly connected to the bottom of the cross bracket 201. A rotating shaft 402 is rotatably connected to the bottom of the cross bracket 201 and inside the fixed sleeve 401. A gear 403 is fixedly connected to the outer wall of the rotating shaft 402. The bottom of the cross bracket 201 is provided with two upper racks 404 and two lower racks 405 adapted to the gears 403. The two upper racks 404 and the two lower racks 405 respectively mesh with the gears 403. The fixed sleeve 401 provides installation support. When the rotating shaft 402 inside rotates, it drives the gear 403 to rotate synchronously. By using the meshing transmission between the gear 403 and the two upper racks 404 and the two lower racks 405, the upper racks 404 and the lower racks 405 can move in opposite or the same direction, thereby driving the connected moving column 202 to slide along the slide groove. The spacing of multiple grinding discs 203 can be adjusted synchronously, quickly adapting to the grinding needs of different areas of the brake pads and improving the device's adaptability to diverse workpieces.

[0029] As one implementation method of this embodiment, such as Figure 4As shown, multiple rectangular through holes are provided on the outer wall of the fixed sleeve 401. One end of each of the two upper racks 404 and the two lower racks 405 passes through the rectangular through holes and extends to the outside of the fixed sleeve 401, where they are fixedly connected to the side walls of the multiple movable columns 202. The two upper racks 404 and the two lower racks 405 are slidably connected to the fixed sleeve 401. The multiple rectangular through holes on the outer wall of the fixed sleeve 401 provide a moving channel for the upper racks 404 and the lower racks 405. After extending through the rectangular perforation to the outside of the fixed sleeve 401, it is fixedly connected to the side walls of multiple moving columns 202 one by one. The upper and lower racks are slidably connected to the fixed sleeve 401, so that when the gear 403 drives the rack to move, the rack can slide smoothly along the rectangular perforation and accurately drive the moving columns 202 to move synchronously along the slide groove. This not only ensures the stability of the linkage between the rack and the moving columns 202, but also limits the movement trajectory of the rack through the rectangular perforation to avoid deviation during the adjustment process and ensure the accuracy of the grinding disc 203 spacing adjustment.

[0030] As one implementation method of this embodiment, such as Figure 2 As shown, the bottom of the rotating shaft 402 passes through the fixed sleeve 401 and extends to its outer side, where a knob 406 is fixedly connected. By passing through the fixed sleeve 401 and connecting the knob 406, the operator can rotate the knob 406 to drive the rotating shaft 402 and gear 403 to rotate, thereby driving the upper rack 404, lower rack 405 and moving column 202 to adjust the spacing of the grinding disc 203. The adjustment process can be manually and precisely controlled without complicated tools, simplifying the operation process, improving the convenience and efficiency of spacing adjustment, and allowing the device to quickly respond to the grinding needs of different areas of the brake pad.

[0031] As one implementation method of this embodiment, such as Figure 5As shown, the replacement component 5 includes a first limiting plate 501 and a second limiting plate 502 slidably connected inside the base 101. The first limiting plate 501 is located on one side of the second limiting plate 502. A second drive motor 503 is fixedly connected to the top of the base 101. A threaded rod 504 is fixedly connected to the output end of the second drive motor 503. The end of the threaded rod 504 away from the second drive motor 503 passes through the first limiting plate 501 and the second limiting plate 502 and is threadedly connected to both the first limiting plate 501 and the second limiting plate 502. The replacement component 5 drives the threaded rod 504 to rotate through the second drive motor 503 inside the base 101. 04 is threadedly connected to the first limiting plate 501 and the second limiting plate 502, and the two limiting plates are slidably connected inside the base 101. When the threaded rod 504 rotates, it drives the two limiting plates to move synchronously along the base 101. This design allows the second limiting plate 502 to be in a standby position to prepare for clamping the new brake pad when the first limiting plate 501 drives the brake pad to the grinding position for processing. After the brake pad on the first limiting plate 501 is ground, it can be quickly replaced by the synchronous movement of the two limiting plates. This not only greatly shortens the waiting time for workpiece replacement and improves the continuous processing efficiency, but also ensures the stability of the brake pad when it is fixed and guarantees the grinding accuracy.

[0032] Working principle:

[0033] First, the base 101 of the main body 1 provides stable support, the fixed bracket 102 carries the component, the groove of the cross bracket 201 allows the moving column 202 to slide, the grinding disc 203 is inserted into the mounting groove of the moving column 202 through the insert block, and is initially fixed by the pin 204 passing through the insertion hole and through hole, and then double locked by the bolt 206 on the fixed block 205 passing through the fixing through hole of the pin 204, realizing the quick replacement and stable operation of the grinding disc, while being flexibly adjustable to adapt to the area of ​​brake pad grinding, improving processing efficiency and accuracy.

[0034] In the drive assembly 3, the lifting plate 301 slides along the inner wall of the fixed bracket 102, driving the lifting bracket 302 to move synchronously. The first drive motor 303 provides rotational power to the cross bracket 201 and the grinding assembly, and works with the hydraulic rod 304 at the top of the fixed bracket 102 to drive the lifting, precisely controlling the pressure and distance between the grinding disc 203 and the brake pad, ensuring the controllability, accuracy and stability of the grinding. The adjustment assembly 4 is supported by the fixed sleeve 401, and the rotating shaft 402 drives the gear 403 to rotate, meshing with the upper rack 404 and the lower rack 405 for transmission. The rectangular through hole drives the moving column 202 to slide, realizing the adjustment of the distance between the grinding disc 203. The knob 406 is easy to operate manually, simplifying the process, improving efficiency, and ensuring that it can quickly adapt to the grinding needs of different areas of the brake pad.

[0035] The replacement component 5 drives the threaded rod 504 to rotate via the second drive motor 503 inside the base 101. Since the threaded rod 504 is threadedly connected to the first limiting plate 501 and the second limiting plate 502, and the two limiting plates are slidably connected inside the base 101, the rotation of the threaded rod 504 causes the two limiting plates to move synchronously along the base 101. This design allows the second limiting plate 502 to be in a standby position to prepare for clamping the new brake pad when the first limiting plate 501 is in the grinding position for processing. After the brake pad on the first limiting plate 501 is ground, the synchronous movement of the two limiting plates enables rapid replacement, which significantly shortens the waiting time for workpiece replacement, improves continuous processing efficiency, and ensures the stability of the brake pad when it is fixed, thus guaranteeing the grinding accuracy.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
