Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The grade slider 106 slides in the grade slide groove 104, driving the grinding saw 105 to translate. This step is used when processing the seal. Because the seal is usually annular, it is often necessary to center it when clamping it during the grinding process. Therefore, when this device clamps the seal, multiple groups of clamping blocks 19 move away or closer together to keep the center at the center of the placement table 13, reducing the time spent on finding the center, and can achieve internal and external clamping, reducing the time required to replace a new seal after grinding, greatly improving work efficiency.

[0028] like Figure 1-4 , Figure 6-7As shown, the bottom of the grinding tool table 1 is fixedly connected to a vacuum cleaner housing 2; the bottom of the grinding tool table 1 is fixedly connected to a sieve plate 21; the inner side of the vacuum cleaner housing 2 is fixedly connected to a support leaf 28; the end of the support leaf 28 away from the vacuum cleaner housing 2 is fixedly connected to a fixed support rod 27; the end of the fixed support rod 27 away from the support leaf 28 is fixedly connected to a fan motor 26; the side of the fan motor 26 away from the fixed support rod 27 is rotatably connected to a rotating column 24; a fan blade 25 is fixedly connected to the middle of the rotating column 24; the end of the rotating column 24 away from the fan motor 26 is fixedly connected to a rotating bar 22; the top of the rotating bar 22 is fixedly connected to a nylon thread 23; the vacuum cleaner housing 2 The bottom is fixed with a threaded opening 29; the outer side of the threaded opening 29 is threadedly connected with a bowl-shaped bottom 200; when working, the fan motor 26 drives the rotating column 24 to rotate, realizes the rotation of the fan blade 25, and drives the rotating bar 22 and the nylon thread 23 to rotate, and cleans the sieve plate 21. The bowl-shaped bottom 200 can be rotated to separate the bowl-shaped bottom 200 from the vacuum cleaner housing 2. This step will generate a lot of dust when polishing the seal, affecting the working environment. At this time, the dust is sucked into the vacuum cleaner housing 2 by the rotation of the fan blade 25. At the same time, the dust will contaminate the sieve plate 21 when passing through the sieve plate 21. At this time, the sieve plate 21 is cleaned by the rotating bar 22 and the nylon thread 23. When too much dust accumulates, the bowl-shaped bottom 200 can be removed to clean its interior.

[0029] like Figure 1 , Figure 3 , Figure 5 , Figure 8 As shown, a fixed block 3 is fixedly connected to one side of the large bracket 107; a cutting fluid hose 31 is fixedly connected to the bottom of the fixed block 3; a nozzle 35 is fixedly connected to the end of the cutting fluid hose 31 away from the fixed block 3; a sleeve 32 is provided in the middle of the cutting fluid hose 31; a flow limiting block 33 is threadedly connected in the middle of the sleeve 32; a rotating block 34 is fixedly connected to the end of the flow limiting block 33; a protective shell 36 is provided on the outside of the nozzle 35; when working, the cutting fluid flows to the nozzle 35 through the cutting fluid hose 31, and when passing through the sleeve 32, the flow limiting block can be driven by rotating the rotating block 34. 33 rotates inside the ferrule 32 to tighten the ferrule 32, thereby controlling the speed at which the cutting fluid is sprayed out of the nozzle 35. When the cutting fluid is not in use, the protective shell 36 can be used to cover it to reduce the pollution of the nozzle 35 by external stains. When the seal is polished in this step, the high temperature generated during the polishing process may continue to accumulate, thereby affecting the polishing accuracy and even causing the surface of the seal to burn. Therefore, when the seal is polished, the seal can be cooled by spraying cutting fluid, which greatly reduces the loss caused by high temperature accumulation during the polishing process.

[0030] like Figure 1 , Figure 3 , Figure 5-6As shown, the product-type slide groove 104 is internally rotatably connected with a rotating screw 4; the middle part of the rotating screw 4 is threadedly connected with a product-type slider 106; the large bracket 107 is fixedly connected to the second servo motor 41 on the side away from the fixed block 3; the output end of the second servo motor 41 is fixedly connected to a fourth gear 43; the rotating screw 4 is fixedly connected to the end close to the second servo motor 41; the middle part of the third gear 42 is meshed with a fourth gear 43; when working, the second servo motor 41 drives the fourth gear 43 to rotate, and drives the third gear 42 meshed with it to rotate, thereby realizing the rotation of the rotating screw 4, so that the product-type slider 106 is more stable when sliding in the product-type slide groove 104. When grinding the seal, this step may make the grinding saw 105 unstable due to the interaction force, so the grinding saw 105 is driven and limited by the rotating screw 4, so that the stability of the working process of the grinding saw 105 is increased, and the working accuracy and work efficiency are improved.

[0031] like Figure 1-3 , Figure 6 As shown, a telescopic rod 5 is fixedly connected to the end of the large sliding groove 100; a small rotating shaft 51 is rotatably connected to the end of the telescopic rod 5; a cleaning scraper 52 is rotatably connected to the middle of the small rotating shaft 51; during operation, the telescopic rod 5 begins to extend and retract, driving the cleaning scraper 52 to start sliding in the large sliding groove 100. Since the small rotating shaft 51 is rotatable, the inclination angle of the cleaning scraper 52 can be adjusted when the cleaning scraper 52 is working. In this step, during the polishing process of the seal, dirt may accumulate in the large sliding groove 100, thereby affecting the normal operation of the equipment. The large sliding groove 100 is cleaned by sliding the cleaning scraper 52 in the large sliding groove 100. The angle of the cleaning scraper 52 can be adjusted to allow the cleaned dirt to be scraped onto the cleaning scraper 52, which is convenient for cleaning and reduces the possibility of dirt affecting the operation of the equipment.

[0032] like Figure 1-3 As shown, a magnetic strip 6 is fixedly connected to the top of the placement table 13; a protective cover plate 61 is provided on the top of the magnetic strip 6; when working, the protective cover plate 61 is placed on the magnetic strip 6, and the magnetic strip 6 will adsorb the protective cover plate 61. In this step, during the grinding process of the seal, the dust generated may enter the inside of the placement table 13 and affect the operation of the internal gear set, so the protective cover plate 61 is raised to shield the gear set to reduce the possibility of operation failure caused by dust entering the gear set.

[0033] like Figure 1-3 , Figure 6 As shown, the side of the clamp block 19 is fixedly connected with an anti-skid pad 7; when the seal is clamped during operation, the anti-skid pad 7 will come into contact with the seal. This step will increase the friction when the seal is clamped, making the operation more stable, and due to the presence of the anti-skid pad 7, the damage to the seal caused by the clamp block 19 will be greatly reduced during clamping.

[0034] Working principle: the first servo motor 11 rotates to drive the first gear 12, the first gear 12 drives the annular rack 14 to rotate in the placement table 13, and the placement table 13 drives multiple sets of second gears 15 to rotate; the second gear 15 drives multiple sets of sliding racks 16 to translate in the first rack groove 17, so that multiple sets of clamping blocks 19 are approached or moved away, the rolling pulley 102 slides in the large sliding groove 100, driving the large bracket 107 to translate on the top of the grinding tool table 1, the rolling slide column 103 passes through the side double sliding groove 101, and plays a role in limiting the large bracket 107, the grade slider 106 slides in the grade slide groove 104, driving the grinding saw 105 to translate, when processing the seal, because the seal is usually annular, it is often necessary to center it when clamping it during the grinding process, so this device is very useful in clamping the seal. When sealing, multiple groups of clamps 19 move away from or close to each other, so that the center is always kept at the center of the placement table 13, reducing the time spent on finding the center, and can achieve internal and external clamping, reducing the time required to replace a new seal after grinding is completed, greatly improving work efficiency, the fan motor 26 drives the rotating column 24 to rotate, realizes the rotation of the fan blades 25, and at the same time drives the rotating bar 22 and the nylon thread 23 to rotate, and the sieve plate 21 is cleaned. The bowl-shaped bottom 200 can be rotated to separate the bowl-shaped bottom 200 from the vacuum cleaner housing 2. When grinding the seal, a large amount of dust will be generated, affecting the working environment. At this time, the dust is sucked into the vacuum cleaner housing 2 through the rotation of the fan blades 25. At the same time, the dust will contaminate the sieve plate 21 when passing through the sieve plate 21. At this time, the sieve plate 21 is cleaned by the rotating bar 22 and the nylon thread 23.When too much dust accumulates, the bowl-shaped bottom 200 can be removed to clean the inside. The cutting fluid flows to the nozzle 35 through the cutting fluid hose 31. When passing through the hoop 32, the limiting block 33 can be driven to rotate inside the hoop 32 by rotating the rotating block 34, so that the hoop 32 begins to tighten, thereby controlling the speed of the nozzle 35 spraying the cutting fluid. When the cutting fluid is not in use, the protective shell 36 can be used to cover it to reduce the pollution of the nozzle 35 by external stains. When grinding the seal, the high temperature generated during the grinding process may continue to accumulate, thereby affecting the grinding accuracy and even causing the surface of the seal to burn. Therefore, when grinding the seal, the seal can be cooled by spraying cutting fluid, which greatly reduces the loss caused by high temperature accumulation during the grinding process. The second servo motor 41 drives the fourth gear 43 to rotate, driving the third gear 42 meshing with it to rotate, realizing the rotation of the rotating screw 4, so that the product slider 106 is more stable when sliding in the product slide groove 104. When grinding the seal, the grinding saw 105 may be unstable due to the interaction force, so the grinding saw 105 is driven and limited by rotating the screw 4, so that the stability of the working process of the grinding saw 105 is increased. , improve working accuracy and working efficiency, the telescopic rod 5 begins to extend and retract, driving the cleaning scraper 52 to start sliding in the large sliding groove 100. Since the small rotating shaft 51 is rotatable, the inclination angle of the cleaning scraper 52 can be adjusted when the cleaning scraper 52 is working. During the polishing process of the seal, dirt may accumulate in the large sliding groove 100, thereby affecting the normal operation of the equipment. The large sliding groove 100 is cleaned by sliding the cleaning scraper 52 in the large sliding groove 100. The angle of the cleaning scraper 52 can be adjusted to make the cleaned dirt scraped on the cleaning scraper 52, which is convenient for cleaning and reduces the impact of dirt on the operation of the equipment. Possibility, the protective cover 61 is placed on the magnetic strip 6, and the magnetic strip 6 will absorb the protective cover 61. During the grinding process of the seal, the dust generated may enter the inside of the placement table 13 and affect the operation of the internal gear set, so the protective cover 61 is raised to shield the gear set to reduce the possibility of dust entering the gear set and causing operation failures. When the seal is clamped, the anti-slip pad 7 will contact the seal. When the seal is clamped, the friction will increase, making the operation more stable, and due to the presence of the anti-slip pad 7, the damage to the seal by the clamping block 19 will be greatly reduced during clamping.
