Description

Technical Field

[0001] This invention relates to the field of sawing technology, and more particularly to a cutting machine for machining screw pumps. Background Technology

[0002] During the processing of core components of screw pumps (such as screw rotors and stator housings), long cylindrical metal bars or tubes typically need to be cut to a fixed length according to the process requirements. Most existing cutting machines used for screw pump processing only have a single sawing function, and their structure usually only includes a sawing machine, a sawing mechanism, and a clamping unit for holding the workpiece.

[0003] However, it's worth considering that when a circular saw blade rotates at high speed to cut metal pipes or bars, it generates a large amount of hot chips (ranging in size from micrometers to millimeters) and fine metal fumes. Under the centrifugal force of the saw blade, these chips and fumes are scattered irregularly at high speeds. The accumulating chips on the saw table can affect the normal operation of the equipment, increase cleaning and maintenance costs, seriously pollute the workshop environment, and the flying chips can easily burn operators. Even more seriously, the fine metal dust can remain suspended in the air and harm the health of operators if inhaled.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a cutting machine for screw pump processing, so as to solve the problems of the above-mentioned flying chips accumulating on the saw table and the fine metal dust being suspended in the air and being inhaled by the operator, which is harmful to health.

A second servo motor is fixedly connected to the frame, and the output end of the second servo motor is fixedly connected to the second rotating shaft. Support seats are provided above and below the second rotating shaft. The support seats have arc-shaped grooves adapted to the finished workpiece.

[0018] The beneficial effects of this invention are as follows: By setting multiple barrier sleeves above the sawing machine, when sawing is performed, the first electric push rod drives the lifting frame to descend, so that the opening at the bottom of the barrier box connects with the corresponding barrier sleeve. Together with the impurity collector, a sealed chamber is formed. This sealed chamber completely surrounds the sawing point, so that the high-temperature metal chips and fumes generated during cutting are confined inside the chamber and cannot splash outwards. This completely solves the problem of chips scattering everywhere and polluting the environment and endangering the health of operators in the prior art. The barrier box is equipped with a connector for connecting to an external air extraction device. During the sawing process, the external air extraction device continuously draws in fine dust from the sealed chamber, while large chips fall directly into the impurity collector installed on the sawing machine through the opening below the barrier sleeve due to gravity. After the cutting is completed, the vibration unit drives the barrier box to vibrate slightly relative to the lifting frame, and transmits the vibration force to the barrier sleeve through the limit bar, so that the two vibrate synchronously. This vibration can effectively shake off the stubborn dust and fine chips adhering to the inner wall, causing them to fall into the impurity collector below, thereby ensuring the cleanliness of the sealed chamber.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0023] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 6The present invention includes a sawing machine 1 and a frame 2 fixedly installed above the sawing machine 1. A plurality of blocking sleeves 3 are provided above the sawing machine 1. The blocking sleeves 3 are provided with through holes 9 for the workpiece 60 to be sawed to pass through. A lifting frame 6 is slidably installed on the frame 2. A first electric push rod 7 is fixedly connected to the frame 2, and the telescopic end of the first electric push rod 7 is fixedly connected to the lifting frame 6. A circular saw blade 4 is provided on the lifting frame 6. A barrier box 5 is fitted around the outside of the circular saw blade 4, and the bottom of the barrier box 5 has an opening that matches the barrier sleeve 3. A rotator for driving the circular saw blade 4 to rotate is installed on the lifting frame 6. A vibration unit that matches the barrier box 5 is installed on the lifting frame 6. A connector for connecting to an external air extraction device is installed on the barrier box 5. Limiting strips 8 that match the barrier sleeve 3 are fixedly connected to both sides of the barrier box 5. A guide unit that matches the barrier sleeve 3 is installed on the frame 2. An impurity collector that matches the barrier sleeve 3 is installed on the sawing machine 1. A clamping drive assembly for driving the workpiece 60 to rotate and translate is installed on the frame 2. When the first electric push rod 7 drives the lifting frame 6 to descend, the barrier sleeve 3 engages with the barrier box 5 and the impurity collector respectively. The saw is assembled into a sealed chamber to confine the chips and dust generated during sawing. An external exhaust device, connected by a connector, sucks up the fine dust from the sealed chamber during sawing. Large particles of impurities generated during sawing fall into the impurity collector through the barrier sleeve 3. A shaking unit drives the barrier box 5 and the barrier sleeve 3 to shake synchronously after sawing, so that the impurities adhering to the inner wall fall off and fall into the impurity collector. The operator places several pieces 60 to be sawed 60 above the sawing machine 1, and the operator drives one end of the piece 60 to be sawed through the corresponding through hole 9. The other end of the piece 60 is fixed by the clamping drive assembly. The barrier box 5 is connected to the external exhaust device by a connector. When sawing is to begin, the clamping drive assembly is used to drive the... Several workpieces 60 to be sawed are rotated, so that one of them rotates to the sawing station. The workpiece 60 drives the corresponding barrier sleeve 3 to move above the impurity collector. Several limiting strips 8 are located on both sides of the barrier sleeve 3. The barrier sleeve 3 is guided by the guide unit to rotate smoothly relative to the frame 2. The circular saw blade 4 is driven to rotate by the rotator, and the first electric push rod 7 drives the lifting frame 6, the circular saw blade 4 and the barrier box 5 to move down synchronously. The barrier box 5 and the impurity collector are assembled together by the barrier sleeve 3. The clamping drive assembly drives the workpiece 60 to be sawed at the sawing station to rotate. The circular saw blade 4 can then saw the rotating workpiece 60. The external air extraction device extracts air from the barrier box 5 through the connecting parts. Dust and large particles of impurities generated during sawing fall into the impurity collector through the barrier sleeve 3. After cutting, the vibration unit drives the barrier box 5 to vibrate relative to the lifting frame 6. The barrier box 5 drives the barrier sleeve 3 to vibrate synchronously through the limit bar 8, so that the impurities adhering to the inner walls of the barrier box 5 and the barrier sleeve 3 fall into the impurity collector. After the vibration ends, the clamping drive assembly drives the workpiece 60 to be sawed at the sawing station to move horizontally, so that the remaining workpiece 60 pushes the finished workpiece cut from the saw to slide out of the barrier sleeve 3. Then, the first electric push rod 7 drives the lifting frame 6 to move upward, so that the barrier box 5 no longer abuts against the barrier sleeve 3, and the circular saw blade 4 is pulled out of the barrier sleeve 3. The clamping drive assembly drives the workpiece 60 to revolve again.This allows the next workpiece 60 to be sawed to rotate to the sawing station. After several workpieces 60 have been sawed once, the clamping drive assembly drives several workpieces 60 to move synchronously relative to the barrier sleeves 3, adjusting the position of the workpieces 60 to be sawed, and the next round of sawing can begin. By setting multiple barrier sleeves 3 above the sawing machine 1, when sawing is performed, the first electric push rod 7 drives the lifting frame 6 to descend, so that the opening at the bottom of the barrier box 5 aligns with the corresponding barrier sleeve 3, forming a sealed chamber with the impurity collector. This sealed chamber completely surrounds the sawing point, so that the high-temperature metal chips and fumes generated during cutting are confined inside the chamber and cannot splash outwards, thus completely solving the problem of chips scattering everywhere and polluting the environment and endangering the health of operators in the prior art. The barrier box 5 is equipped with a connector for connecting to an external air extraction device. During the sawing process, the external air extraction device continuously draws in fine dust from the sealed chamber, while large chips fall directly into the impurity collector installed on the sawing machine 1 through the opening below the barrier sleeve 3 due to gravity. After cutting, the vibration unit drives the barrier box 5 to vibrate slightly relative to the lifting frame 6, and transmits the vibration force to the barrier sleeve 3 through the limit bar 8, so that the two vibrate synchronously. This vibration can effectively shake off the stubborn dust and fine chips adhering to the inner wall, causing them to fall into the impurity collector below. This ensures the cleanliness of the sealed chamber, effectively removing stubborn dust adhering to the inner wall. Combined with the clamping drive assembly, the workpiece 60 is moved horizontally to eject the finished product, achieving automated material handling. Furthermore, the clamping drive assembly drives multiple workpieces 60 to revolve and rotate, respectively achieving rapid station switching and rotary feed during sawing. Combined with the first electric push rod 7 controlling the lifting frame 6 and the circular saw blade 4, a complete automated cycle of switching, sawing, dust removal, material handling, and resetting is formed, significantly improving the sawing efficiency and cutting quality of cylindrical workpieces using the screw pump.

[0024] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10The rotating device includes a first rotating shaft 10 rotatably mounted on a lifting frame 6. A first servo motor 11 is fixedly connected to the lifting frame 6. One end of the first rotating shaft 10 is fixedly connected to the output end of the first servo motor 11, and the other end of the first rotating shaft 10 is fixedly connected to a circular saw blade 4. The shaking unit includes a rotating shell 12 rotatably sleeved outside the first rotating shaft 10. A sealing sleeve 13 is sleeved outside the rotating shell 12, and the sealing sleeve 13 is fixedly connected to a barrier box 5. A guide groove 1 is formed on the inner wall of the sealing sleeve 13. 4. A guide bar 15 is slidably provided in the guide groove 14, and the guide bar 15 is fixedly connected to the rotating shell 12. Several support sleeves 17 are fixedly connected to the lifting frame 6. A movable sleeve 16 is slidably provided in the support sleeve 17. The movable sleeve 16 is fixedly connected to the barrier box 5, and the side of the barrier box 5 facing the lifting frame 6 is in contact with the support sleeve 17. A tension spring 18 is provided in the movable sleeve 16, and the two ends of the tension spring 18 are fixedly connected to the lifting frame 6 and the barrier box 5 respectively. A device adapted to the barrier box 5 is installed on the lifting frame 6. The pushing component includes several second electric push rods 19 fixedly mounted on the lifting frame 6. The telescopic ends of the second electric push rods 19 are fixedly connected to push plates 20 for pushing the barrier box 5 to move horizontally. The guiding unit includes a rotating ring 21 rotatably mounted on the frame 2. Two limiting sleeves 23 are fixedly connected to the barrier sleeve 3. Limiting rods 22 are slidably provided inside the limiting sleeves 23. The limiting rods 22 and the rotating ring 21 are fixedly connected. A fixing ring 24 is fixedly connected to the frame 2. An annular groove 2 is formed on the inner wall of the fixing ring 24. 5. A guide block 26 is fixedly connected to the limiting sleeve 23, and the guide block 26 is slidably installed in the annular groove 25. Two clearance holes 27 adapted to the guide block 26 are opened on both sides of the inner wall of the annular groove 25. The impurity collector includes a collection box 28 fixedly installed on the top of the saw 1. The top of the collection box 28 is provided with an arc-shaped surface adapted to the blocking sleeve 3. The top of the collection box 28 is provided with an impurity inlet hole 29 adapted to the blocking sleeve 3. The outer side of the blocking sleeve 3 is fixedly fitted with a baffle plate 30 adapted to the arc-shaped surface. The clamping drive assembly drives the workpiece 60 to revolve, which in turn drives the barrier sleeve 3, limit sleeve 23, limit rod 22, and rotating ring 21 to rotate relative to the frame 2. The limit sleeve 23 drives the guide block 26 to slide in the annular groove 25. When the barrier sleeve 3 rotates to the sawing station, it slides above the collection box 28, and the baffle plate 30 contacts the arc-shaped surface of the collection box 28. The barrier sleeve 3 is located above the impurity inlet hole 29, and moves between several limit bars 8. At this time, the guide block 26 at the sawing station is located on one side of the clearance hole 27, and the tension spring 18 is in a stretched state. The extension spring 18 applies tension to the barrier box 5, causing the barrier box 5 to abut against the support sleeve 17. The first servo motor 11 drives the first rotating shaft 10 to rotate, which in turn drives the circular saw blade 4 to rotate. The first rotating shaft 10 rotates relative to the rotating shell 12. After sawing is completed, the first servo motor 11 stops driving the first rotating shaft 10 and the circular saw blade 4 to rotate. The second electric push rod 19 drives the push plate 20 to push the barrier box 5 and the movable sleeve 16 to slide relative to the support sleeve 17. The barrier box 5 also drives the sealing sleeve 13 to slide relative to the guide strip 15 and the rotating shell 12. The barrier box 5 drives the barrier sleeve 3 and the limiting sleeve 2 to slide relative to the guide strip 15 and the rotating shell 12 through the limiting strip 8. 3. The relative limiting rod 22 slides, and the limiting sleeve 23 drives the guide block 26 to slide out of the annular groove 25 through the clearance hole 27. Then, the second electric push rod 19 drives the push plate 20 to move in the opposite direction so that the push plate 20 no longer contacts the barrier box 5. The tension spring 18 drives the movable sleeve 16 and the barrier box 5 to move in the opposite direction to the initial position. The barrier box 5 hits the support sleeve 17, and the barrier box 5 drives the barrier sleeve 3 to move in the opposite direction to the initial position through the limiting strip 8. The guide block 26 slides into the annular groove 25 again, which makes the barrier box 5 and the barrier sleeve 3 shake in the horizontal direction. The barrier sleeve 3 drives the baffle plate 30 relative to the arc of the collection box 28. The surface slides, and the design of the baffle plate 30 prevents the impurity inlet hole 29 from being exposed. Impurities in the barrier box 5 and the barrier sleeve 3 fall into the collection box 28 through the impurity inlet hole 29. Before the clamping drive assembly drives the workpiece to be sawed 60 to revolve, the first electric push rod 7 drives the lifting frame 6 to move upward, and the barrier box 5 no longer contacts the barrier sleeve 3, so as to avoid the barrier box 5 interfering with the revolution of the barrier sleeve 3. When the clamping drive assembly drives the workpiece to be sawed 60 to revolve, the limiting strip 8 limits the position of the barrier sleeve 3, so as to prevent the barrier sleeve 3 and the limiting sleeve 23 from shaking horizontally, so that the guide block 26 can smoothly slide from one side of the clearance hole 27 into other positions in the annular groove 25.

[0025] Example 3, based on Example 2, by Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 11The connecting components include an extraction pipe 42 fixedly installed on the barrier box 5, a connecting pipe 43 fixedly connected to the frame 2, and the connecting pipe 43 and the extraction pipe 42 connected by a flexible hose 44. The frame 2 is provided with a feeding structure for transferring the finished workpiece from the sawing station to the feeding station. The feeding structure includes a second rotating shaft 31 rotatably installed on the frame 2, and the second rotating shaft 31 is rotatably connected to the collection box 28. A second servo motor 32 is fixedly connected to the frame 2, and the output end of the second servo motor 32 is fixedly connected to the second rotating shaft 31. Support seats 33 are provided above and below the second rotating shaft 31. The support seats 33 have arc-shaped grooves adapted to the finished workpiece. Two rotating bars 34 are fixedly sleeved on the outside of the second rotating shaft 31. Two sliding grooves 35 are provided on the support seats 33, and the two ends of the rotating bars 34 slide... The rotating bar 34 is installed in two sliding grooves 35. The two ends of the rotating bar 34 are respectively provided with grooves 36. Several first compression springs 37 are provided in the grooves 36. The two ends of the first compression springs 37 are respectively fixedly connected to the inner wall of the groove 36 and the inner wall of the sliding groove 35. An arc plate 58 adapted to the support base 33 is fixedly connected on the sawing machine 1. A presser adapted to the support base 33 is provided above the sawing machine 1. The presser includes two lifting seats 38 set above the sawing machine 1. A third electric push rod 41 is fixedly connected to both the frame 2 and the collection box 28. The telescopic end of the third electric push rod 41 is fixedly connected to the corresponding lifting seat 38. The top and bottom ends of the lifting seat 38 are fixedly connected to the pressure plate 39. The two sides of the support base 33 are fixedly connected to the support column 40 adapted to the pressure plate 39. A sealing ring 59 is fixedly connected to the inner wall of the through hole 9. Connecting pipe 43 is connected to an external air extraction device. When the external air extraction device is started, the dust in the barrier box 5 can be discharged into the collection device through the extraction pipe 42, hose 44 and connecting pipe 43 in sequence. The second servo motor 32 drives the second rotating shaft 31 to rotate. The second rotating shaft 31 drives the support base 33 to rotate synchronously through the rotating bar 34, so that one of the support bases 33 moves to the sawing station. The third electric push rod 41 drives the lifting seat 38 to move down. The lifting seat 38 drives the pressure plate 39 located above to press the support column 40 and support base 33 located above to move down relative to the rotating bar 34. The compression spring 37 is in a compressed state to prevent the support seat 33 from interfering with the rotation of the workpiece 60 to be sawed to the sawing station. When the workpiece 60 is rotated to the sawing station, the lifting seat 38 is driven to move up to the initial height by the third electric push rod 41, so that the pressure plate 39 no longer presses against the support column 40. The first compression spring 37 drives the support seat 33 to move up relative to the rotating bar 34 to the initial height. At this time, the support seat 33 can support the workpiece 60 to be sawed at the sawing station. After the workpiece 60 is sawn, the clamping drive assembly drives the workpiece 60 to be sawed at the sawing station to translate, so that the remaining workpiece 60 can be sawed. The finished workpiece cut by the saw slides out from the barrier sleeve 3, and slides relative to the support base 33. Finally, the finished workpiece slides completely above the support base 33. When it is necessary to rotate the finished workpiece to the collection station on the sawing machine 1, the second servo motor 32 drives the second rotating shaft 31 to rotate. The second rotating shaft 31 then drives the support base 33 and the finished workpiece to one side of the arc plate 58. The arc plate 58 limits the position of the finished workpiece, preventing it from falling off the arc groove on the support base 33. Finally, the support base 33 drives the finished workpiece to roll from the arc plate 58 to the collection station on the sawing machine 1. The arc groove on the support 33 limits the position of the finished workpiece, preventing it from rolling on the collection station of the sawing machine 1. The lifting seat 38 is driven to move upward by the third electric push rod 41, so that the pressure plate 39 below drives the support column 40 and support seat 33 located at the collection station to move upward, so that the finished workpiece is no longer located in the arc groove on the support seat 33. The operator can then remove the finished workpiece from the sawing machine 1. The finished workpiece can be smoothly transferred from the cut to the sawing machine 1. The design of the sealing ring 59 prevents dust in the blocking sleeve 3 from overflowing through the connection between the workpiece to be cut 60 and the through hole 9 during the cutting process.

[0026] Example 4, based on Example 1, is... Figure 1 , Figure 2 , Figure 12 and Figure 13The clamping drive assembly includes a translation seat 45 mounted above the saw 1. A translator for driving the translation seat 45 to move is mounted on the frame 2. A rotary seat 46 is rotatably connected to the translation seat 45. A third servo motor 47 is fixedly connected to the translation seat 45. The output end of the third servo motor 47 is fixedly connected to the rotary seat 46. Several self-rotating seats 49 are rotatably connected to the rotary seat 46, and the number of self-rotating seats 49 is the same as that of the blocking sleeve 3. A prism 61 is slidably mounted on the self-rotating seat 49. A four-jaw chuck 50 is fixedly connected to one end of the prism 61, and a first synchronization disk 48 is fixedly connected to the other end of the prism 61. The first synchronization disk 48 and the self-rotating seat 49 are connected by several second compression springs 51. A motor base 52 is provided below the translation base 45. A fourth servo motor 53 is fixedly connected to the motor base 52. The output end of the fourth servo motor 53 is fixedly connected to a second synchronous disk 54 that is compatible with the first synchronous disk 48. Several fourth electric push rods 62 are fixedly connected to the translation base 45. The telescopic ends of the fourth electric push rods 62 are fixedly connected to the motor base 52. The translator includes a lead screw 55 rotatably mounted on the frame 2. A guide column 56 is fixedly connected to the frame 2. Both the lead screw 55 and the guide column 56 pass through the translation base 45. The lead screw 55 and the translation base 45 are connected by a threaded connection. A fifth servo motor 57 is fixedly connected to the frame 2. The output end of the fifth servo motor 57 is fixedly connected to the lead screw 55. The end of the workpiece 60 to be sawed is clamped and fixed by the four-jaw chuck 50. The rotary seat 46 is driven to rotate by the third servo motor 47. The rotary seat 46 then drives the four-jaw chuck 50 and the workpiece 60 to revolve through the self-rotating seat 49. When the corresponding workpiece 60 is rotated to the sawing position, the fourth electric push rod 62 drives the motor seat 52 and the second synchronous plate 54 to translate, so that the second synchronous plate 54 abuts against the corresponding first synchronous plate 48. The second compression spring 51 is in a compressed state and applies pressure to the first synchronous plate 48, so that the first synchronous plate 48 and the second synchronous plate 54 are in close contact. The second synchronous plate 54 is driven to rotate by the fourth servo motor 53. The second synchronous plate 54 then drives the first synchronous plate 48, the prism 61, the four-jaw chuck 50 and the workpiece 60 to rotate synchronously through friction. After the workpiece 60 is sawn, the fourth electric push rod 62 drives the motor seat 52 and the second synchronous plate 54 to rotate synchronously. The fourth servo motor 53 moves synchronously, and the second synchronous disk 54 pushes the first synchronous disk 48, prism 61 and four-jaw chuck 50 to slide relative to the rotating seat 49. The workpiece to be sawed 60 can then be driven to slide out of the barrier sleeve 3. Then, the fourth electric push rod 62 drives the motor seat 52 and the second synchronous disk 54 to move in the opposite direction to the initial position. The second compression spring 51 drives the first synchronous disk 48 and prism 61 to move in the opposite direction relative to the rotating seat 49 to the initial position. The third servo motor 47 drives the rotating seat 46 to rotate again. The rotating seat 46 can then drive another workpiece to be sawed 60 to rotate to the sawing station through the rotating seat 49 and the four-jaw chuck 50. The fifth servo motor 57 drives the lead screw 55 to rotate. The lead screw 55 can then drive the translation seat 45 to translate relative to the guide post 56 and the frame 2. After several workpieces to be sawed 60 have been sawed in one round, several workpieces to be sawed 60 can be synchronously translated relative to the barrier sleeve 3.
