When the other end of the part needs to be processed, Driving one of the cylinders 8 can move the clamping assembly 9 that is not in contact with the part toward the part. At this time, by driving the two clamping assemblies 9, the processed end of the part can be clamped, and at the same time, the other clamping assembly 9 releases the clamping of the part, and under the action of the cylinder 8, the clamping assembly 9 can move in the opposite direction and pull the part out. At this time, by driving one of the cylinders 8, the clamping assembly 9 close to the processed end of the part can be moved to the periphery of the part and clamp the part. At this time, the other clamping assembly 9 releases the clamping of the part, and under the action of the cylinder 8, the processed end of the part can be pushed into one of the clamping assemblies 9, so that the longer parts can be flipped over without the need for employees to manually flip the parts, thereby reducing the labor intensity of employees.

[0033] Reference Figure 2-Figure 4The bottom of the support seat 1 is fixedly connected with a water tank 11, and the interior of the water tank 11 is fixedly connected with a water spray assembly 12. The water spray assembly 12 consists of a water pump, a water outlet hose and a connecting pipe, wherein the connecting pipe is fixed to the motor 4, and the connecting pipe can be moved when the motor 4 moves. The water outlet hose is arranged on the outside of the support seat 1, and the two ends of the water outlet hose are respectively connected with the output end of the water pump and the end of the connecting pipe away from the motor 4. When in use, the water inside the water tank 11 can enter the water outlet hose and be sprayed to the processing position of the parts through the connecting pipe by driving the water pump, so as to cool the tool 6 and the parts, and the water spray assembly 12 is a prior art and will not be described in detail in this article. The interior of the water tank 11 is fixedly connected with a filter plate 13, and iron filings in the water can be filtered through the filter plate 13, so that the water can be recycled. The middle part of the water tank 11 is rotatably connected with a cleaning assembly.

[0034] Reference Figure 3 and Figure 4 The cleaning assembly includes a screw rod 14, which is rotatably connected to the middle part of the water tank 11. The outer periphery of the screw rod 14 is threadedly connected to a nut seat 15, and the nut seat 15 is slidably connected to the middle part of the water tank 11. A limiting groove 28 is provided in the middle part of the water tank 11, and the nut seat 15 is slidably connected to the middle part of the limiting groove 28. The nut seat 15 can be limited by the limiting groove 28, so that the nut seat 15 can be driven to move in parallel when the screw rod 14 rotates, and at the same time, the nut seat 15 is prevented from separating from the water tank 11.

[0035] Reference Figure 2-Figure 4 A compression spring 16 is fixedly connected to the inside of the nut seat 15, and a scraper 17 is fixedly connected to the other end of the compression spring 16. The scraper 17 is in contact with the filter plate 13, and a flap 18 is rotatably connected to the outside of the water tank 11. When the nut seat 15 moves, the scraper 17 can push the iron filings filtered on the top of the filter plate 13. At the same time, when the flap 18 is squeezed by an object, it will flip over, so that the scraper 17 can push the iron filings out of the water tank 11, which can prevent the filter plate 13 from being blocked. At the same time, under the action of the compression spring 16, the scraper 17 and the filter plate 13 can be prevented from not contacting each other, thereby improving the cleaning effect of the filter plate 13. A driving component is fixedly connected to the side of the water tank 11 away from the flap 18.

[0036] Reference Figure 3 The driving assembly includes a second motor 19, which is fixedly connected to a side of the water tank 11 away from the flap 18. The screw rod 14 can be rotated by driving the second motor 19, so that the iron filings filtered by the filter plate 13 can be easily cleaned.

[0037] Reference Figure 5 and Figure 6The connecting component includes a mounting plate 1 20 and a mounting plate 21. The mounting plate 1 20 is fixedly connected to the outer side of the turntable 5, and the mounting plate 21 is fixedly connected to the side of the tool 6 close to the turntable 5. A positioning block 22 is fixedly connected to the side of the mounting plate 21 close to the turntable 5. A positioning groove 10 is provided on the side of the mounting plate 1 20 close to the mounting plate 21. The positioning block 22 and the positioning groove 10 are plugged together. The positioning block 22 can be limited by the positioning groove 10, so that the mounting plate 1 20 and the mounting plate 21 can be quickly aligned, which can improve the installation speed of the tool 6. A compression spring 23 is fixedly connected to the inside of the mounting plate 1 20, and a clamping block 24 is fixedly connected to the other end of the compression spring 23. The clamping block 24 contacts the positioning block 22. A clamping groove 25 is provided in the middle of the positioning block 22, and the clamping block 24 and the clamping groove 25 are plugged together.

[0038] Reference Figure 5 and Figure 6 When the positioning block 22 enters the middle of the mounting plate 20, it will contact the card block 24 and squeeze the card block 24 to move the card block 24. When the card block 24 moves, the compression spring 23 can be compressed, and then the positioning block 22 can be completely inserted into the mounting plate 20 and the mounting plate 20 and the mounting plate 21 can be in contact. At this time, the card slot 25 moves to the original position of the card block 24 and the card block 24 is not squeezed by external force. Under the action of the compression spring 23, the card block 24 can be bounced into the card slot 25, and then the tool 6 can be installed. The middle part of the mounting plate 20 is slidably connected with a disassembly component.

[0039] Reference Figure 6 The disassembly assembly includes a cross plate 26, which is slidably connected to the middle part of the mounting plate 20. The bottom of the cross plate 26 is rotatably connected to a connecting plate 27, and the other side of the connecting plate 27 is rotatably connected to a partition, which is fixedly connected between the compression spring 23 and the block 24. By pressing the cross plate 26, one side of the connecting plate 27 can be moved and the connecting plate 27 will flip between the cross plate 26 and the partition. While the connecting plate 27 moves, the partition can be squeezed, thereby moving the partition, and then the block 24 can be pulled out from the middle part of the slot 25. At this time, the tool 6 can be disassembled, and then the tool 6 can be quickly replaced if it is damaged. A paddle plate is fixedly connected to the side of the cross plate 26 away from the mounting plate 20, and the cross plate 26 can be pressed down more conveniently and comfortably through the paddle plate.

[0040] Working principle: When in use, when it is necessary to process the other end of the part, by driving one of the cylinders 8, the clamping assembly 9 that is not in contact with the part can be moved toward the part. At this time, by driving the two clamping assemblies 9, the processed end of the part can be clamped, and at the same time, the other clamping assembly 9 can be released from the clamping of the part, and under the action of the cylinder 8, the clamping assembly 9 can be moved in the opposite direction and the part can be pulled out, so that the part can be turned over. When the part is long, by driving one of the cylinders 8, the clamping assembly 9 close to the processed end of the part can be moved to the periphery of the part and clamp the part. At this time, the other clamping assembly 9 can be released from the clamping of the part, and under the action of the cylinder 8, the processed end of the part can be pushed into one of the clamping assemblies 9, so that the long part can be turned over, and the employees do not need to turn the parts manually, thereby reducing the labor intensity of the employees.

[0041] Among them, the water inside the water tank 11 can be sprayed to the area where the parts are processed through the water spray component 12, thereby reducing the temperature of the tool 6 and the parts, thereby improving the processing effect. The iron filings generated after cutting will fall into the water tank 11 with the sprayed water. At this time, the iron filings in the water can be filtered through the filter plate 13, thereby preventing the iron filings from damaging the water spray component 12, and at the same time allowing the water to be recycled. When impurities accumulate on the top of the filter plate 13 and water cannot pass through, the screw rod 14 can be rotated by driving the second motor 19. At the same time, when the screw rod 14 rotates, the nut seat 15 can drive the scraper 17 to move, thereby pushing the iron filings accumulated on the top of the filter plate 13 out of the water tank 11 through the flap 18. At the same time, under the action of the first compression spring 16, the scraper 17 can continue to contact with the filter plate 13, thereby improving the cleaning effect.

[0042] By inserting the positioning block 22 into the mounting plate 20, when the positioning block 22 enters, the card block 24 will be squeezed and the card block 24 will compress the compression spring 23. When the slot 25 moves to the original position of the card block 24, the card block 24 can be bounced into the slot 25 under the action of the compression spring 23, and then the tool 6 can be installed. By pressing the cross plate 26 and under the action of the connecting plate 27, the card block 24 and the slot 25 can be separated, and then the tool 6 can be disassembled, thereby improving the assembly and disassembly efficiency of the tool 6, and the tool 6 can be quickly replaced when the tool 6 is damaged.
