Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing equipment, and particularly relates to a piston rod cutting device based on the manufacture of large hydraulic equipment. Background Art

[0002] In the field of manufacturing large hydraulic equipment, as a key component, the processing accuracy and quality of the piston rod directly affect the overall performance and reliability of the hydraulic equipment. The piston rod is usually made of metal and needs to have high-precision dimensional tolerances, good surface roughness, and excellent material properties to ensure stable operation under harsh working conditions such as high pressure and high load.

[0003] A piston rod cutting device based on the manufacture of large hydraulic equipment disclosed in the patent publication number "CN 108453278 B", by precisely measuring and fine-tuning according to the set position to meet the requirements of the set value, is applicable to the cutting processing of various metal plates. Although it is an intelligent metal cutting control device that improves work efficiency and product accuracy, in the actual use process, during the cutting process, it is necessary to spray cutting fluid to cool the workpiece and wash away the chips. The sprayed cutting fluid is usually accompanied by cutting debris and is difficult to be separately processed. Since the cutting fluid and debris cannot be efficiently separated, the cutting fluid is difficult to be reused, which not only causes a great waste of resources but also significantly increases the production cost.

[0017] Preferably, a cutting fluid tank is fixedly connected to the sliding table. A liquid outlet pipe is connected to the cutting fluid tank. One end of the liquid outlet pipe penetrates through the sliding table and is arranged on one side of the cutting tool. An opening is provided on the cutting fluid tank to penetrate through the sliding table and is connected to the bottom of the separation box. A runner is arranged on one side of the sliding table and is fixedly connected to the second lead screw.

[0018] Preferably, two annular support frames are fixedly connected to the sliding table. The sleeve is rotatably connected between the two annular support frames.

[0022] The present invention has the following beneficial effects:

[0023] Through the grinding assembly, when the gear ring on the three-jaw chuck drives the gear to rotate, the gear drives the slide rail to rotate, so that the slide rail drives the sleeve to rotate. The grinding plate is attached to the cut piston rod through the electric telescopic rod. Since the gear ring drives the gear to rotate in opposite directions, the rotation direction of the piston rod driven by the three-jaw chuck is opposite to the rotation direction of the sleeve. The grinding plate can efficiently grind the cut piston rod, quickly remove the burrs and unevenness left by cutting, greatly reduce the surface roughness of the piston rod, and meet higher precision standards.

[0024] Through the anti-winding assembly, when the cutting assembly works, the iron chips generated after cutting will fall into the separation box along with the cutting fluid. The sleeve drives the first transmission wheel to rotate through the first belt. The first transmission wheel drives the worm to drive the first worm gear to rotate through the first connecting rod. The first worm gear drives the bidirectional lead screw to rotate through the second connecting rod. The bidirectional lead screw drives the two cutting knives to continuously contact each other, thereby clamping off the dropped long iron chips, avoiding the long iron chips from winding around each other and getting stuck between the key components of the cutting equipment (between the key components of the cutting machine tool), causing equipment jamming or even damage and triggering production accidents.

[0025] By separating the components, when two worm gears drive two second worm wheels to rotate, the third connecting rods on the two second worm wheels drive two magnetic rollers to rotate in opposite directions respectively. The magnetic rollers adsorb the iron filings falling into the cutting fluid in the separation box by virtue of their own magnetism, while the filter plate below the magnetic rollers will secondary-filter the cutting fluid to filter out the remaining iron filings in the cutting fluid. Under the rotation of the magnetic rollers, the iron filings are left on the scraping blades. At the same time, the magnetic rollers drive the bi-directional reciprocating lead screw to rotate through the second transmission wheel and the third transmission wheel. Under the rotation of the bi-directional reciprocating lead screw, the brush reciprocates to scrape the iron filings on the scraping blades, magnetic rollers and filter plate into the chip collection box. In this way, the cutting fluid after removing the iron filings will flow into the cutting fluid tank for reuse, saving the production cost. Brief Description of the Drawings

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Embodiment 1:

[0039] Refer to Figure 1 - Figure 4 And Figure 9 A piston rod cutting device for large hydraulic equipment manufacturing includes a cutting machine tool 1, a cutting assembly, a grinding assembly, an anti-winding assembly, and a separation assembly;

[0040] The cutting machine tool 1 is equipped with a three-jaw chuck 2 for clamping the cutting piece. A gear ring 3 is fixedly connected to the outside of the three-jaw chuck 2. A piston rod 4 is clamped on the three-jaw chuck 2. When the three-jaw chuck 2 rotates, it can drive the piston rod 4 and the gear ring 3 to rotate. A gear 37 is rotatably connected to the cutting machine tool 1, and the gear 37 is meshed with the gear ring 3. When the gear ring 3 rotates, it can drive the gear 37 to rotate. A first lead screw 11 is rotatably connected to the cutting machine tool 1. There is a motor in the cutting machine tool 1 that can drive the first lead screw 11 to rotate. A first slide bar 10 is fixedly connected to the cutting machine tool 1. A sliding table 8 is threadedly connected to the first lead screw 11, and the sliding table 8 is slidably connected to the first slide bar 10. When the first lead screw 11 rotates, it can drive the sliding table 8 to slide on the first lead screw 11 and the first slide bar 10, so as to continuously move along with the cutting of the piston rod 4. Two annular support frames 26 are fixedly connected to the sliding table 8. When the sliding table 8 drives the cutting assembly to slide, it can drive the annular support frames 26 to slide simultaneously. A sleeve 16 is rotatably connected between the two annular support frames 26, enabling the sleeve 16 to rotate and displace at the same time;

[0041] The cutting assembly is used for machining and cutting the piston rod 4;

[0042] The grinding assembly is used for grinding the surface of the piston rod 4 after cutting;

[0043] The anti-winding assembly is used to prevent the cutting iron filings from being too long and causing entanglement;

[0044] The separation assembly is used to separate the iron filings in the cutting fluid

[0045] The cutting assembly consists of a cutting seat 9, a cutting tool 15, a second lead screw 39 and a second slide bar 23. The second lead screw 39 is rotatably connected to the sliding table 8, and the second slide bar 23 is fixedly connected to the sliding table 8. A runner is provided on one side of the sliding table 8 and fixedly connected to the second lead screw 39. By rotating the runner, the second lead screw 39 can be rotated. The cutting seat 9 is slidably connected to the second lead screw 39 and the second slide bar 23. The cutting tool 15 is installed on the cutting seat 9. The cutting tool 15 is used for cutting the piston rod 4. When the second lead screw 39 rotates, it can drive the cutting seat 9 and the cutting tool 15 to slide, so as to adjust the cutting depth of the piston rod 4.

[0046] The grinding assembly consists of a slide rail 5, a sleeve 16, several electric telescopic rods 17, and three grinding plates 6. One end of the slide rail 5 is fixedly connected to the gear 37, and the other end is rotatably connected to the cutting machine tool 1. When the gear 37 rotates, it can drive the slide rail 5 to rotate. The sleeve 16 is slidably sleeved on the slide rail 5. When the slide rail 5 rotates, it can drive the sleeve 16 to rotate. Several electric telescopic rods 17 are fixedly installed on the outer side of the sleeve 16. The three grinding plates 6 are respectively fixedly connected to the output ends of the several electric telescopic rods 17. The electric telescopic rods 17 can adjust the outward extension of the grinding plates 6, so that the grinding plates 6 are attached to the surface of the cut piston rod 4.

[0047] In this embodiment, the cutting machine tool 1 is started, so that the three-jaw chuck 2 drives the piston rod 4 to rotate at a high speed. The distance of the cutting tool 15 is adjusted by the second lead screw 39. Subsequently, under the rotation of the first lead screw 11, the cutting tool 15 approaches the piston rod 4 to cut it. At the same time, the gear ring 3 on the three-jaw chuck 2 drives the gear 37 to rotate, and the gear 37 drives the slide rail 5 to rotate, so that the slide rail 5 drives the sleeve 16 to rotate. The grinding plates 6 are attached to the cut piston rod 4 by the electric telescopic rods 17. Since the gear ring 3 drives the gear 37 to rotate in the opposite direction, the rotation direction of the three-jaw chuck 2 driving the piston rod 4 is opposite to the rotation direction of the sleeve 16. The grinding plates 6 can efficiently grind the cut piston rod 4, quickly remove the burrs and unevenness left by cutting, and greatly reduce the surface roughness of the piston rod 4, reaching a higher precision standard.

[0048] Embodiment 2:

[0049] Different from Embodiment 1, referring to Figure 3 、 Figure 5 、 Figure 6 and Figure 9 , this embodiment also has the following further content:

[0050] A separation box 13 is fixedly installed on the sliding table 8 for processing cutting fluid containing iron filings. An installation plate 14 is fixedly connected to the sliding table 8. A first worm gear 18 is rotatably connected to the installation plate 14. A second connecting rod 22 is fixedly connected to the first worm gear 18. When the first worm gear 18 rotates, it can drive the second connecting rod 22 to rotate. A first transmission wheel 28 is rotatably connected to the annular support frame 26. A first belt 25 is wound around the outside of the first transmission wheel 28. The first belt 25 is wound around the sleeve 16. When the sleeve 16 rotates, it can drive the first transmission wheel 28 to rotate through the first belt 25. A first connecting rod 27 is rotatably connected to the outside of the annular support frame 26. The first connecting rod 27 is fixedly connected to the first transmission wheel 28. Two worm shafts 19 are fixedly connected to one end of the first connecting rod 27. The first worm gear 18 is meshed with the worm shafts 19. When the first transmission wheel 28 rotates, it can drive the first connecting rod 27 to rotate, so that the first connecting rod 27 drives the two worm shafts 19 to make the first worm gear 18 rotate, and the first worm gear 18 can drive the second connecting rod 22 to rotate.

[0051] The anti-winding assembly is composed of a bidirectional lead screw 31, a third sliding rod 30 and two cutting knives 29. The bidirectional lead screw 31 is rotatably connected to the inner wall of the separation box 13. The third sliding rod 30 is fixedly connected to the inner wall of the separation box 13. The two cutting knives 29 are respectively and simultaneously slidably connected to the bidirectional lead screw 31 and the third sliding rod 30. Cutting tools are respectively arranged on the inner walls on both sides of the separation box 13 corresponding to the two cutting knives 29. The second connecting rod 22 is fixedly connected to the bidirectional lead screw 31. In this way, when the second connecting rod 22 drives the bidirectional lead screw 31 to rotate, the two cutting knives 29 can continuously slide and contact reciprocally, and at the same time, they continuously contact reciprocally with the cutting tools on the inner wall of the separation box 13, so as to cut off the longer iron filings in the cutting fluid.

[0052] In this embodiment, when the cutting assembly works, the iron filings generated after cutting will fall into the separation box 13 along with the cutting fluid. The sleeve 16 drives the first transmission wheel 28 to rotate through the first belt 25. The first transmission wheel 28 drives the worm shaft 19 to drive the first worm gear 18 to rotate through the first connecting rod 27. The first worm gear 18 drives the bidirectional lead screw 31 to rotate through the second connecting rod 22. The bidirectional lead screw 31 drives the two cutting knives 29 to continuously contact each other, so as to clamp and cut off the falling longer iron filings, avoid the longer iron filings from winding around each other and getting stuck between the key components of the cutting equipment (between the key components of the cutting machine tool 1), causing equipment jamming or even damage, and triggering production accidents.

[0053] Embodiment Three:

[0054] Refer to Figure 3 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10 Compared with Embodiment One and Embodiment Two, in this embodiment:

[0055] A cutting fluid tank 12 is fixedly connected to the sliding table 8 for storing cutting fluid. A liquid outlet pipe 7 is connected to the cutting fluid tank 12. A water pump for spraying the cutting fluid through the liquid outlet pipe 7 is arranged in the cutting fluid tank 12. One end of the liquid outlet pipe 7 penetrates through the sliding table 8 and is arranged on one side of the cutting tool 15, capable of accurately cooling and dissipating heat from the piston rod 4 during cutting. An opening is provided on the cutting fluid tank 12, which penetrates through the sliding table 8 and is connected to the bottom of the separation box 13, enabling the separated and filtered cutting fluid in the separation box 13 to flow into the cutting fluid tank 12. Two second worm wheels 20 are rotatably connected to the mounting plate 14. Two worm shafts 19 are respectively meshed with the two second worm wheels 20. Third connecting rods 21 are respectively fixedly connected to the two second worm wheels 20. The serration directions of the two second worm wheels 20 are respectively opposite. In this way, when the two worm shafts 19 rotate, the two second worm wheels 20 and the two third connecting rods 21 can rotate in opposite directions to each other. A bi-directional reciprocating lead screw 34 is rotatably connected in the separation box 13. Chip outlets 38 are respectively provided on both sides of the separation box 13 for discharging iron chips in the cutting fluid. Chip collection boxes 24 are respectively provided on both sides of the separation box 13 for collecting iron chips. A second transmission wheel 42 is rotatably connected to the separation box 13. The second transmission wheel 42 is fixedly connected to one end of the magnetic roller 32. A third transmission wheel 40 is rotatably connected to one side of the separation box 13. The third transmission wheel 40 is fixedly connected to one end of the bi-directional reciprocating lead screw 34. A second belt is wound around the outer sides of the second transmission wheel 42 and the third transmission wheel 40. When the magnetic roller 32 drives the second transmission wheel 42 to rotate, the third transmission wheel 40 can be driven to rotate through the second belt 41, so that the bi-directional reciprocating lead screw 34 rotates. Both the second transmission wheel 42 and the third transmission wheel 40 are arranged at the gap between the separation box 13 and the chip collection box 24, capable of preventing iron chips from falling on the transmission wheels. A brush 36 is threadedly connected to the bi-directional reciprocating lead screw 34. The brush 36 is slidably connected in the separation box 13. The upper bristles of the brush 36 are attached to the two magnetic rollers 32 and the two scraping knives 33, and the lower bristles are attached to the filter plate 35. When the bi-directional reciprocating lead screw 34 rotates, the brush 36 can be driven to clean the cutting iron chips on the magnetic rollers 32, the scraping knives and the filter plate 35, enabling them to be discharged through the chip outlet 38 into the chip collection box 24. The two third connecting rods 21 are respectively fixedly connected to the two magnetic rollers 32. When the two third connecting rods 21 rotate in opposite directions to each other, the two magnetic rollers 32 can be driven to rotate in opposite directions to each other.

[0056] The separation assembly consists of two magnetic rollers 32, two scraping knives 33 and a filter plate 35. The two magnetic rollers 32 are respectively rotatably connected to the inner wall of the separation box 13. When the iron chips after cutting fall into the separation box 13 along with the cutting fluid, the magnetic rollers 32 can adsorb the iron chips. The two scraping knives 33 are respectively fixedly connected to the inner walls on both sides of the separation box 13. When the two magnetic rollers 32 rotate, the scraping knives 33 can scrape off the iron chips on the magnetic rollers 32 and leave them on the scraping knives 33. The filter plate 35 is fixedly connected in the separation box 13 for secondary filtering of iron chips in the cutting fluid, further ensuring the quality of the recycled cutting fluid.

[0057] In this embodiment, when two worm gears 19 drive two second worm wheels 20 to rotate, the third connecting rods 21 on the two second worm wheels 20 drive two magnetic rollers 32 to rotate in opposite directions respectively. The magnetic rollers 32 adsorb the iron filings in the cutting fluid falling into the separation box 13 by virtue of their own magnetism. The filter plate 35 below the magnetic rollers 32 will perform secondary filtration on the cutting fluid to filter out the residual iron filings in the cutting fluid. Under the rotation of the magnetic rollers 32, the iron filings are left on the scraper 33. At the same time, the magnetic rollers 32 drive the bidirectional reciprocating lead screw 34 to rotate through the second transmission wheel 42 and the third transmission wheel 40. Under the rotation of the bidirectional reciprocating lead screw 34, the brush 36 reciprocates to scrape the iron filings on the scraper 33, the magnetic rollers 32 and the filter plate 35 into the chip collecting box 24. In this way, the cutting fluid after removing the iron filings will flow into the cutting fluid tank 12 for reuse, saving the production cost.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
