Description

Technical Field

[0001] This invention relates to the field of automotive clutch face grinding technology, specifically to a novel dust-free grinding device for wear-resistant automotive clutch faces. Background Technology

[0002] The automotive clutch is a key component of the vehicle's transmission system. The performance of its core component—the clutch facet (friction plate)—directly affects the vehicle's transmission efficiency, shifting smoothness, service life, and safety reliability. To ensure that the clutch has stable friction, good thermal attenuation performance, and wear resistance during engagement and disengagement, and to eliminate dimensional and positional tolerances during the manufacturing process, the friction surfaces must be precision-polished after the facet is sintered or cured with resin.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 10 This invention provides a technical solution: a novel dust-free grinding device for wear-resistant automotive clutch face plates, comprising: a machine tool frame 1, a conveyor belt 2 rotatably connected to the machine tool frame 1, a sealed chamber 3 movably mounted on the top of the machine tool frame 1 by screws, one end of a dust suction pipe 8 movably mounted on the sealed chamber 3, a dust suction mechanism provided at the other end of the dust suction pipe 8, and doors 36 symmetrically opened on the two end faces of the sealed chamber 3. A door panel mounting groove 18 is opened on the inner wall of the door 36, a door panel 19 movably inserted into the door panel mounting groove 18, and a door opening mechanism is provided in the door panel mounting groove 18. The closed control mechanism has a support plate 22 and a hydraulic cylinder 26 fixed on the inner wall of the sealed chamber 3. The top of the support plate 22 abuts against the bottom of the conveyor belt 2. A motor 27 is fixed on the piston rod of the hydraulic cylinder 26. A polishing disc mounting mechanism is fixed on the drive shaft of the motor 27. A polishing disc 37 is movably mounted on the polishing disc mounting mechanism. Several sets of clutch mounting slots 5 are fixed on the conveyor belt 2. A pressure plate 6 is movably inserted into one set of clutch mounting slots 5. A wear-resistant clutch face plate 7 is fixed on the pressure plate 6. Cylinders 4 are fixed on two symmetrical end faces of the sealed chamber 3. The piston rod of the cylinder 4 is movably inserted into the sealed chamber 3.

[0021] The pressure plate 6, equipped with the wear-resistant clutch face plate 7, is inserted into the clutch mounting groove 5. Then, the hatch panel 19 retracts completely into the hatch panel mounting groove 18, and the hatch 36 opens. The conveyor belt 2 running on the machine tool frame 1 transports the pressure plate 6 and the wear-resistant clutch face plate 7 into the sealed chamber 3. The piston rods of the two sets of cylinders 4 extend to the same distance, clamping the pressure plate 6 in the middle. Then, the hatch panel 19 extends out of the hatch panel mounting groove 18 and presses against the top of the conveyor belt 2. The support plate 22 supports the bottom of the conveyor belt 2 to prevent it from being crushed. Then, the piston rod of the hydraulic cylinder 26 extends, causing the motor 27 and the grinding disc 37 mounted on the grinding disc mounting mechanism to move downwards until the grinding disc 37 abuts against the top of the wear-resistant clutch face plate 7. Then, the drive shaft of the motor 27 drives the grinding disc mounting mechanism and the grinding disc 37 to rotate, grinding the wear-resistant clutch face plate 7 through the rotation of the grinding disc 37. Simultaneously, the dust extraction mechanism starts, using... The dust collection pipe 8 collects the dust in the sealed chamber 3 into the dust collection mechanism, avoiding the hazards caused by dust diffusion. This new dust-free grinding device for wear-resistant automotive clutch plates forms a sealed space through the sealed chamber 3, the door panel 19, and the conveyor belt 2. The wear-resistant clutch plate 7 is transported by the conveyor belt 2. During transport, the door panel 19 retracts into the door panel mounting groove 18, and the door 36 is open to facilitate the entry and exit of the pressure plate 6 and the wear-resistant clutch plate 7 into the sealed chamber 3. During grinding, the door panel 19 extends from the door panel mounting groove 18 to seal the door 36 and prevent dust leakage. The grinding disc 37 is driven by the spring 21 to rotate at high speed to grind the wear-resistant clutch plate 7. At the same time, the dust collection mechanism sucks out the dust from the sealed chamber 3 and collects it. This makes the grinding of the wear-resistant clutch plate 7 more intelligent and efficient, while creating a dust-free environment for the processing workshop, greatly improving the health of the operators and the service life of the equipment.

[0022] Example 2: Based on Example 1, in order to realize the dust collection and cleaning of the dust collection mechanism, the dust collection mechanism includes: a bucket cover 9, a dust collection bucket 12 is installed at the bottom of the bucket cover 9 by a threaded connection, an air extractor 10 and a dustproof net 11 are fixed at the bottom of the bucket cover 9, an exhaust pipe 15 is fixed at the top of the air extractor 10, the exhaust pipe 15 is movably inserted into the bucket cover 9, a dust cleaning port 13 is opened on the side wall of the dust collection bucket 12, and a cover 14 is movably installed in the dust cleaning port 13 by a screw.

[0023] When grinding the wear-resistant clutch face plate 7, the exhaust fan 10 is turned on to discharge the air in the dust collection bin 12 to the outside through the exhaust pipe 15. This reduces the air pressure in the space enclosed by the lid 9 and the dust collection bin 12, while the air pressure in the space enclosed by the sealed chamber 3, the door panel 19, and the conveyor belt 2 is higher. Therefore, the air in the sealed chamber 3 will enter the dust collection bin 12 through the suction pipe 8. When the air is circulating, the dust in the sealed chamber 3 is carried by the air, thus sucking the dust in the sealed chamber 3 into the dust collection bin 12. The dustproof net 11 has small mesh size, allowing air to pass through while preventing dust from passing through, thus protecting the exhaust fan 10 and collecting the dust in the dust collection bin 12. After grinding is completed, the suction pipe 8 is removed from the sealed chamber 3, and the dust collection bin 12 can be moved to the dust treatment area. Then, the cover 14 is opened, and the dust in the dust collection bin 12 can be cleaned out through the dust removal port 13.

[0024] Example 3: Based on Example 2, in order to achieve the disassembly and assembly of the sealed chamber 3 and the suction pipe 8, a connector 16 is rotatably connected to the end of the suction pipe 8 away from the lid 9. The connector 16 has a cylindrical structure and an internal thread on its inner wall. A dust discharge port is fixed at the top of the sealed chamber 3. The dust discharge port of the sealed chamber 3 has a circular cylindrical structure and an external thread on its outer wall. The external thread on the dust discharge port of the sealed chamber 3 mates with the internal thread of the connector 16. A sealing gasket 17 is fixed at the top of the dust discharge port of the sealed chamber 3, and the bottom end of the suction pipe 8 rests against the top of the sealing gasket 17.

[0025] By tightening the connector 16 onto the dust outlet of the sealed chamber 3 via the threaded connection, the sealed chamber 3 and the suction pipe 8 can be installed. At this time, the end of the suction pipe 8 is pressed against the sealing gasket 17, and the sealing gasket 17 is pressed against the top of the dust outlet of the sealed chamber 3, thereby sealing the gap between the suction pipe 8 and the sealed chamber 3 and preventing dust from leaking out. By twisting the connector 16 in the opposite direction to remove the connector 16 from the dust outlet of the sealed chamber 3, the sealed chamber 3 and the suction pipe 8 can be separated.

[0026] Example 4: Based on Example 3, in order to realize the opening and closing of the hatch, the hatch opening and closing control mechanism includes: an electromagnet mounting bracket 20, which is movably mounted in the hatch door panel mounting groove 18 by screws. Several sets of electromagnets 23 are fixed on the electromagnet mounting bracket 20. When the electromagnets 23 are energized, they generate a suction force on the hatch door panel 19. A spring 21 is fixed between the hatch door panel 19 and the electromagnet mounting bracket 20. A controller 25 is fixed at one end of the electromagnet mounting bracket 20 that extends out of the hatch door panel mounting groove 18. Signal power supply lines 24 are fixed between the controller 25 and the several sets of electromagnets 23.

[0027] The controller 25 can be connected to an external power source via a power cord. When the controller 25 supplies power to the electromagnet 23 via the signal power supply line 24, the electromagnet 23 generates an attractive force on the hatch door panel 19, causing the hatch door panel 19 to move upward and fully retract into the hatch door panel mounting groove 18, thus opening the hatch 36. At this time, the spring 21 is compressed. When the controller 25 stops supplying power to the electromagnet 23, the spring 21 pushes the hatch door panel 19 downward under its own elasticity, pressing the hatch door panel 19 tightly against the top of the conveyor belt 2, thus closing the hatch 36.

[0028] Example 5: Based on Example 4, in order to realize the replacement of the polishing disc 37, the polishing disc mounting mechanism includes: a first polishing disc mounting plate 28 and a second polishing disc mounting plate 29. Both the first polishing disc mounting plate 28 and the second polishing disc mounting plate 29 are semi-circular cylindrical structures. A locking rod 35 is fixed on the inner wall of the first polishing disc mounting plate 28 and the second polishing disc mounting plate 29. The locking rod 35 is a rectangular rod structure. The polishing disc 37 is a circular plate structure. A slot 34 is formed on the side wall of the polishing disc 37. The slot 34 is rectangular. The device has a groove structure, and the locking rod 35 is movably inserted into the locking groove 34. Two sets of plug-in rods 31 are fixed on the first polishing disc mounting plate 28. The plug-in rods 31 have a rectangular rod structure. Two sets of plug-in grooves 30 are opened on the second polishing disc mounting plate 29. The plug-in grooves 30 have a rectangular groove structure. The two sets of plug-in rods 31 are movably inserted into the two sets of plug-in grooves 30 respectively. A hand-tightening screw 33 is rotatably connected to the second polishing disc mounting plate 29. The plug-in rods 31 have screw holes 32. The hand-tightening screw 33 is installed in the screw holes 32 through threaded connection.

[0029] Remove the sealed chamber 3 from the machine tool frame 1, then unscrew the hand screw 33 from the screw hole 32. The first polishing disc mounting plate 28 and the second polishing disc mounting plate 29 can then be separated at both ends. As the first polishing disc mounting plate 28 and the second polishing disc mounting plate 29 separate, the retaining rod 35 exits from the retaining slot 34, allowing the old polishing disc 37 to be removed. Then, insert the retaining rod 35 on the first polishing disc mounting plate 28 into one set of retaining slots 34 on the new polishing disc 37. Next, insert the connecting rod 31 into the hand screw 33, so that the retaining rod 35 on the second polishing disc mounting plate 29 is inserted into the other set of retaining slots 34. Finally, tighten the hand screw 33 into the screw hole 32, and the new polishing disc 37 can be installed on the first polishing disc mounting plate 28 and the second polishing disc mounting plate 29, thus replacing the polishing disc 37.

[0030] In actual use, the pressure plate 6, on which the wear-resistant clutch face 7 is installed, is inserted into the clutch mounting groove 5. Then, the hatch panel 19 is fully retracted into the hatch panel mounting groove 18, and the hatch 36 is open. The conveyor belt 2 running on the machine tool frame 1 conveys the pressure plate 6 and the wear-resistant clutch face 7 into the sealed chamber 3. The piston rods of the two sets of cylinders 4 extend to the same distance, clamping the pressure plate 6 in the middle. Then, the hatch panel 19 extends out of the hatch panel mounting groove 18 and presses against the top of the conveyor belt 2. The support plate 22 supports the bottom of the conveyor belt 2 to prevent the conveyor belt 2 from being crushed. Then, the piston rod of the hydraulic cylinder 26 extends, causing the motor 27 and the polishing disc 37 mounted on the polishing disc mounting mechanism to move downward until the polishing disc 37 abuts against the top of the wear-resistant clutch face 7. Then, the drive shaft of the motor 27 drives the polishing disc mounting mechanism and the polishing disc 37 to rotate. The wear-resistant clutch face 7 is polished by the rotation of the polishing disc 37. At the same time, the dust collection mechanism is activated. The dust in the sealed chamber 3 is collected by the suction pipe 8 and then collected by the suction mechanism to avoid the hazards caused by dust diffusion. This new dust-free grinding device for wear-resistant automotive clutch plates forms a closed space through the sealed chamber 3, the door panel 19, and the conveyor belt 2. The wear-resistant clutch plate 7 is transported by the conveyor belt 2. During transport, the door panel 19 retracts into the door panel mounting groove 18, and the door 36 is open to facilitate the entry and exit of the pressure plate 6 and the wear-resistant clutch plate 7 into the sealed chamber 3. During grinding, the door panel 19 extends from the door panel mounting groove 18 to seal the door 36 to prevent dust leakage. The grinding disc 37 is driven by the spring 21 to rotate at high speed to grind the wear-resistant clutch plate 7. At the same time, the suction mechanism sucks out the dust from the sealed chamber 3 and collects it. This makes the grinding of the wear-resistant clutch plate 7 more intelligent and efficient, and at the same time creates a dust-free environment for the processing workshop, which greatly improves the health of the operators and the service life of the equipment.
