Description

Technical Field

[0001] This utility model relates to the field of end cap processing technology, and in particular to an end cap grinding device with a positioning auxiliary structure. Background Technology

[0002] End caps are a key component in the industrial field, and they come in a variety of types, such as motor end caps, bearing end caps, and water pump end caps. They mainly serve to close, seal, position, or protect internal components. During the production and processing of end caps, they need to be polished to improve the surface roughness, making them smooth and flat, reducing friction and wear, and providing a clean, flat substrate with good adhesion for subsequent processes such as spraying and coating.

[0003] When grinding end caps, a positioning auxiliary structure is generally required to fix the end caps to prevent them from moving or loosening during processing, which would affect the grinding effect. For example, an end cap grinding device disclosed in patent number CN219987061U places the end face between a first clamping body and a second clamping body. Turning the drive rod rotates the mounting part, and the drive rod pushes the second clamping body towards the first clamping body under the action of the slide rail, thereby clamping and positioning the end cap. However, this device clamps the end cap from the outside, and the clamping block itself will block part of the end cap surface. When it is necessary to grind the edge area of ​​the end cap, the clamp must be loosened first, the end cap position adjusted, and then re-fixed. The operation is cumbersome and affects the efficiency of continuous operation. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an end cap grinding device with a positioning auxiliary structure to solve the problem that existing grinding devices are not conducive to grinding the edge of the end cap.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an end cap grinding device with a positioning auxiliary structure, including a base; A fixed platform is provided at the center of the top of the base, and a positioning mechanism is provided on the top of the fixed platform. An end cap body is placed on the outside of the positioning mechanism, and the positioning mechanism includes a fixed plate provided above the fixed platform. A turntable is provided at the center of the top of the fixed plate, and transmission rods are evenly provided on the top of the turntable through a rotating shaft. One end of each transmission rod is connected to a connector through the rotating shaft, and one end of each connector is provided with a positioning plate. A frame is provided on one side of the end cap body, and a third drive motor is installed inside the frame via a cylinder. A grinding wheel is installed at the output end of the third drive motor via a roller, and the grinding wheel contacts the outer side of the end cap body.

[0006] Preferably, a first drive motor is fixed to the top of the fixed platform, and the output end of the first drive motor is connected to the turntable via a roller.

[0007] With the above structure, the first drive motor can provide stable power, and the roller drives the turntable to rotate, providing an automated power source for the extension and retraction of the positioning plate, ensuring that the positioning process is stable and controllable.

[0008] Preferably, each of the fixing plates below the connector is provided with a slide rail, and the bottom of each connector is slidably connected to the slide rail via a slider.

[0009] With the above structure, the sliding cooperation between the slider and the slide rail can be used to limit the movement trajectory of the positioning plate, ensuring that it can extend and retract smoothly along a straight line and improve positioning accuracy.

[0010] Preferably, the positioning plates are all arc-shaped, and the outer side of the positioning plates is evenly distributed with raised strips, all of which are made of rubber.

[0011] With the above structure, the arc-shaped positioning plate can fit against the inner wall of the end cap body, and the rubber protrusions can increase friction and avoid damaging the inner wall of the end cap, thereby improving the stability and protection of the fixation.

[0012] Preferably, a gear is provided at the bottom of the frame, and a second drive motor is provided at the bottom inside the frame. The output end of the second drive motor is connected to the gear through a roller. A fixing ring is provided on the base outside the fixed platform, and teeth that mesh with the gear are evenly distributed on the outer side of the fixing ring.

[0013] With the above structure, the second drive motor can be used to drive the gear to mesh with the teeth of the fixed ring, thereby driving the frame to make a circular motion along the fixed ring, so as to realize the grinding wheel's circumferential grinding of the outer side of the end cover.

[0014] Preferably, the bottom of the frame is evenly provided with clamping wheels, and all clamping wheels are engaged in the fixing ring.

[0015] With the above structure, the clamping wheel can be inserted into the fixing ring to help support the frame, reduce the shaking when the gears mesh, and ensure the stability of the frame's circumferential movement.

[0016] Preferably, a dust collection box is provided on the top of the frame, and an exhaust fan is provided on one side of the dust collection box. An air inlet hood is provided on the other side of the dust collection box through an air guide pipe. A first filter and a second filter are respectively provided in the center of the interior of the dust collection box.

[0017] With the above structure, the exhaust fan can draw grinding dust into the dust collection box through the air intake hood, and purify the air after it is filtered by the first and second filters, thus improving the working environment.

[0018] The end cap grinding device with a positioning auxiliary structure provided by this utility model has the following advantages: The system comprises a base, a fixed platform, an end cap body, and a positioning mechanism. The positioning mechanism includes a first drive motor, a fixed plate, a positioning plate, a turntable, a transmission rod, a connecting piece, a slide rail, and a slider. During grinding, the end cap body is first placed over the positioning mechanism. The first drive motor drives the turntable to rotate clockwise, causing three sets of transmission components at the top of the turntable to push the connecting piece outwards. The slider at the bottom of the connecting piece slides on the slide rail, thereby driving the positioning plate to extend straight outwards. This, in turn, supports and fixes the end cap body from the inside, providing positioning assistance and preventing deviation or displacement during grinding. Simultaneously, it relies on the first drive motor... A single drive motor provides power, eliminating the need for manual screw rotation or clamp adjustment, thus reducing manual operation steps and waiting time. The three sets of transmission rods move synchronously, enabling rapid fixing and loosening of the end cap body. This makes it suitable for efficient operations in mass production scenarios. Furthermore, there is no need to change to special clamps for different sizes of end cap bodies. Simply adjusting the stroke of the first drive motor can accommodate end cap bodies with different inner diameters within a certain range. At the same time, the fixing force acts on the inside of the end cap body, tightening it from the inside while its outer surface is fully exposed, which is beneficial for grinding the outer edge area of ​​the end cap body.

[0019] The system comprises a fixed ring, teeth, gears, a frame, clamping wheels, a second drive motor, a third drive motor, a cylinder, and a grinding wheel. The fixed ring is mounted on a base outside the fixed platform. The second drive motor drives the gears to rotate, and the gears mesh with the teeth, causing the gears to move in a circular motion along the outside of the fixed ring. This drives the frame and grinding wheel to move around the outside of the end cap body. At the same time, the third drive motor drives the grinding wheel to rotate, thereby polishing the outside of the end cap body. There is no need for manual pushing of the polishing components or adjustment of the polishing angle, reducing the intensity of manual operation. It can automatically complete the polishing of the entire circumference after one clamping, greatly reducing manual intervention and significantly improving efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The present invention provides an end cap grinding device with a positioning auxiliary structure, including a base 1; Please see Figure 1-3 A fixed platform 2 is provided at the center of the top of the base 1, and a positioning mechanism 4 is provided on the top of the fixed platform 2. An end cap body 3 is placed on the outside of the positioning mechanism 4. The positioning mechanism 4 includes a fixed plate 402 provided above the fixed platform 2. A turntable 404 is provided at the center of the top of the fixed plate 402. A transmission rod 405 is evenly provided on the top of the turntable 404 through a rotating shaft. One end of each transmission rod 405 is connected to a connector 408 through a rotating shaft. One end of each connector 408 is provided with a positioning plate 403. A slide rail 406 is provided on the fixed plate 402 below the connector 408. The bottom of each connector 408 is slidably connected to the slide rail 406 through a slider 407. A first drive motor 401 is fixed on the top of the fixed platform 2, and the output end of the first drive motor 401 is connected to the turntable 404 through a roller. The end cap body 3 is placed over the positioning mechanism 4 on the top of the fixed platform 2. The first drive motor 401 is started, and its output end drives the turntable 404 to rotate clockwise through the roller. When the turntable 404 rotates, the three sets of transmission rods 405 evenly arranged on the top push the connector 408 to extend outward. At the same time, the slider 407 at the bottom of the connector 408 slides along the slide rail 406 on the fixed plate 402, driving the positioning plate 403 to extend outward in a straight line. The positioning plates 403 are all arc-shaped, and the outer side of the positioning plates 403 is evenly distributed with protrusions 409. The protrusions 409 are all made of rubber. The rubber protrusions 409 on the outer side of the positioning plate 403 contact the inner wall of the end cap body 3, and support and fix the end cap body 3 from the inside, which plays a positioning auxiliary role and prevents deviation and displacement during the grinding process. By relying on the first drive motor 401 for power, there is no need for manual rotation of the screw or adjustment of the clamp, which reduces manual operation steps and waiting time. Moreover, the three sets of transmission rods 405 move synchronously, which can quickly complete the fixing and loosening of the end cap body. It is suitable for efficient operation in mass production scenarios. Furthermore, there is no need to change special clamps for different sizes of end cap bodies 3. By simply adjusting the stroke of the first drive motor 401, it can be adapted to end cap bodies 3 with different inner diameters within a certain range. At the same time, the fixing force acts on the inside of the end cap body 3, which tightens the end cap body 3 from the inside. Its outer surface is fully exposed, which is conducive to grinding the outer edge area of ​​the end cap body 3 and is less likely to produce grinding dead corners. Please see Figure 4 A frame 6 is provided on one side of the end cap body 3, and a third drive motor 10 is provided inside the frame 6 through a cylinder 9. A grinding wheel 7 is provided at the output end of the third drive motor 10 through a roller, and the grinding wheel 7 contacts the outer side of the end cap body 3. A gear 13 is provided at the bottom end of the frame 6, and a second drive motor 8 is provided at the bottom inside the frame 6. The output end of the second drive motor 8 is connected to the gear 13 through a roller. A fixing ring 5 is provided on the base 1 outside the fixing platform 2, and teeth 15 that mesh with the gear 13 are evenly distributed on the outer side of the fixing ring 5. Clamping wheels 14 are evenly provided at the bottom of the frame 6, and the clamping wheels 14 are all inserted into the fixing ring 5. After fixing, the second drive motor 8 and the third drive motor 10 inside the frame 6 are started. The output end of the second drive motor 8 drives the gear 13 to rotate through the roller. The gear 13 meshes with the teeth 15 of the fixing ring 5 on the outer base 1 of the fixing platform 2, so that the gear 13 moves in a circle along the outer side of the fixing ring 5. At the same time, the clamping wheel 14 at the bottom of the frame 6 slides in the fixing ring 5 to assist in the guidance, driving the frame 6 and the grinding wheel 7 to move around the outer side of the end cap body 3. The output end of the third drive motor 10 drives the grinding wheel 7 to rotate at high speed through the roller. At the same time, the cylinder 9 inside the frame 6 is adjusted. The cylinder 9 pushes the third drive motor 10 and the grinding wheel 7 closer to the outer side of the end cap body 3, so that the grinding wheel 7 contacts the outer side of the end cap body 3 for grinding. There is no need to manually push the grinding components or adjust the grinding angle, which reduces the intensity of manual operation. It can automatically complete the grinding of the entire circumference of the end cap body 3 after one clamping, greatly reducing manual intervention and significantly improving efficiency. Please see Figure 5 The top of the frame 6 is equipped with a dust collection box 11, and a dust collection box 11 is equipped with an exhaust fan 16 on one side. The other side of the dust collection box 11 is equipped with an air inlet hood 12 through an air guide pipe. A first filter screen 17 and a second filter screen 18 are respectively installed in the center of the inside of the dust collection box 11. During the polishing process, the exhaust fan 16 on one side of the dust collection box 11 is turned on, and the dust generated during polishing is sucked into the dust collection box 11 through the air intake hood 12 connected by the air guide pipe. The dust passes through the first filter screen 17 and the second filter screen 18 inside the dust collection box 11 in sequence, and then clean air is discharged. The first filter screen 17 and the second filter screen 18 are both made of activated carbon, and the filtration effect is good. After the outer side of the end cover body 3 is polished, the second drive motor 8 and the third drive motor 10 are turned off, and the first drive motor 401 is controlled to reverse, driving the turntable 404 to rotate counterclockwise. The transmission rod 405 pulls the connecting piece 408 and the positioning plate 403 to reset, the end cover body 3 is released, and the polished end cover body 3 is removed to complete the entire process.
