In addition, the above-mentioned device is limited by the structure when in use and cannot adapt to a large range of different types of sealing rings. The processing range is small, and the loading and unloading are slow, the interval time is long, and it is easy to encounter the problem of not being able to process the sealing ring due to lubrication and resistance reduction.

[0019] Beneficial effects of the present invention:

[0020] (1) When loading, the limit push rod is first retracted, and the limit assembly and the cutting assembly are away from the filling barrel. Then the rotary cylinder is rotated by a set angle. In this embodiment, it is set to rotate ninety degrees, which is convenient for the staff to install several installation rings with interference fit and sealing ring bodies on the filling barrel, and make adjacent installation rings abut each other, so that as many sealing ring bodies as possible can be processed in the same batch of processing. Then the rotary cylinder is returned to its position, and under the lifting and lowering adjustment of the lifting push rod, the filling barrel and the limit push rod are made coaxial. Then the limit push rod pushes the limit assembly to dock with the filling barrel, and then moves the push ring, and pushes the installation ring toward the limit assembly in turn. The transmission screw is rotated by the second motor to push the transmission ring to move, and the transmission ring moves the push ring through the transmission block, so that the push ring is pushed in turn. The mounting ring is pushed onto the limit assembly, and at the same time, the second mounting box is rotated by the first motor, and the filling cylinder is rotated, thereby driving the mounting ring and the sealing ring body, and the peripheral burrs of the sealing ring body are processed by the cutting assembly. After the processing is completed, the limit push rod contracts and moves the limit assembly, so that the suspended mounting ring falls with the processed sealing ring body, and then the limit assembly is repeatedly docked with the filling cylinder. When the first motor rotates the second mounting box and drives the filling cylinder to rotate, the limit block is correspondingly engaged with the clamping groove, so that the filling cylinder drives the limit column, which is connected to the support column through rotation, and is connected to the connecting ring through rotation of the second limit ring, thereby reducing the resistance during rotation and improving the stability of the sealing ring body during the cutting process, thereby accurately and quickly processing each sealing ring body;

[0021] (2) When the periphery of the sealing ring body is cut, the limiting push rod extends and pushes the limiting post connected to the support post, so that the outer surface of one end of the limiting post abuts against the outer surface of one end of the containing tube. At this time, the side surface of the second limiting ring abuts against the side surface of the first mounting ring. Then, under the push of the pushing ring, the first mounting ring and the installed sealing ring body move to the limiting post. The first mounting ring pushes the second limiting ring, and then pushes each transmission post through the first limiting ring. The transmission post is forced to move toward the limiting push rod, stretching the telescopic spring. Then, the cutting assembly cooperates with the rotation of the containing tube to cut the periphery of the sealing ring body. Cutting. After the cutting is completed, the limit push rod contracts, and the transmission column moves toward the limit push rod, so that a gap is generated between the transmission column and the containing cylinder. At the same time, under the elastic force of the telescopic spring, the transmission column pushes the first limit ring, and pushes the first mounting ring to move toward the gap between the transmission column and the containing cylinder through the second limit ring. When the gap between the transmission column and the containing cylinder is greater than the thickness of the mounting ring and the sealing ring body, the suspended mounting ring falls with the processed sealing ring body, thereby completing one processing, and repeating the above steps to process the second, third and several sealing ring bodies, thereby realizing continuous cutting processing;

[0022] (3) Adjust the spacing of the adjusting cross bars on both sides according to the diameter of the sealing ring body, adjust the position of the supporting column on the adjusting cross bar according to the thickness of the sealing ring body, determine the position of the adjusting cross bar by the contact between the positioning bolt and the supporting cross bar, and determine the position of the supporting column by the limit bolt, so that the cutting push rod and the sealing ring body are coplanar, and the cutting head is accurately pushed by the cutting push rod, so that the cutting head can accurately and fully cut the outer periphery of the sealing ring body. When the processing of the current sealing ring body is completed, the cutting push rod is retracted, so that the spacing of the cutting heads is greater than the diameter of the sealing ring body, which facilitates the sealing ring body to fall as the mounting ring falls in the air, and then repeatedly extends and retracts. The cutting push rod is retracted, so that the sealing ring body can be processed quickly and accurately, and it can adapt to sealing ring bodies of different diameters and thicknesses. When the cutting head and the sealing ring body are cutting, the suction filter continuously sucks, forming a negative pressure in the air duct, bellows and air duct. The negative pressure of the air duct absorbs the particles and dust generated by cutting, and transmits them to the suction filter through the bellows and air duct, thereby reducing pollutants in the air and improving the processing environment. Through the elasticity of the bellows and the sliding connection with the supporting column, the air duct moves with the movement of the cutting head under the support of the mounting seat and the mounting frame, so as to maintain the absorption efficiency.

[0034] In this embodiment, when loading, the limiting push rod 3 is first retracted, and the limiting assembly 9 and the cutting assembly 10 are away from the filling tube 7. Then the rotary cylinder 4 is rotated to a set angle. In this embodiment, it is set to rotate ninety degrees, which is convenient for the staff to install several installation rings 44 with interference fit and sealing ring bodies 45 on the filling tube 7, and make adjacent installation rings 44 abut against each other, so that as many sealing ring bodies 45 as possible can be processed in the same batch of processing. Then the rotary cylinder 4 is returned to its position, and under the lifting and lowering adjustment of the lifting push rod 2, the filling tube 7 and the limiting push rod 3 are made coaxial, and then the limiting push rod 3 is set to rotate. The positioning push rod 3 pushes the limiting assembly 9 to dock with the containing cylinder 7, and then moves the pushing ring 8 to push the installation ring 44 toward the limiting assembly 9 in turn. By rotating the second installation box 6 and the containing cylinder 7, the installation ring 44 and the sealing ring body 45 are driven, and the peripheral burrs of the sealing ring body 45 are processed by the cutting assembly 10. After the processing is completed, the limiting push rod 3 contracts and moves the limiting assembly 9, so that the suspended installation ring 44 falls with the processed sealing ring body 45, and then repeatedly docks the limiting assembly 9 with the containing cylinder 7, so that each sealing ring body 45 can be processed accurately and quickly.

[0035] A first motor 13 for rotating the second mounting box 6 is installed in the first mounting box 5, a second motor 14 is installed in the second mounting box 6, and a transmission screw 15 is rotatably connected in the containing cylinder 7. One end of the transmission screw 15 passes through the side wall of the containing cylinder 7 and the second mounting box 6 and is fixedly connected to the drive shaft of the second motor 14. A transmission ring 19 is threadedly sleeved on the transmission screw 15, and a plurality of transmission blocks 17 uniformly distributed at equal angles are fixedly connected to the outer periphery of the transmission ring 19. A limiting slide 16 corresponding to the transmission block 17 is opened on the outer periphery of the containing cylinder 7. The transmission block 17 passes through the limiting slide 16 and is slidably connected to the limiting slide 16. The transmission ring 19 is connected to the push ring 8 through the transmission block 17;

[0036] In this embodiment, the transmission screw 15 is rotated by the second motor 14 to push the transmission ring 19 to move, and the transmission ring 19 moves the pushing ring 8 through the transmission block 17, so that the mounting ring 44 is pushed onto the limit assembly 9 in turn through the pushing ring 8. At the same time, the second mounting box 6 is rotated by the first motor 13, and the filling cylinder 7 is rotated, thereby driving the mounting ring 44 and the sealing ring body 45, and the sealing ring body 45 is cut.

[0037] The limiting assembly 9 includes a support column 20, one end of the support column 20 is fixedly connected to the telescopic end of the limiting push rod 3, and the other end of the support column 20 is rotatably connected to the limiting column 21. The middle part of the support column 20 is fixedly sleeved with a support plate 22, and the middle outer side of the limiting column 21 is sleeved with a first limiting ring 23. There is a distance between the first limiting ring 23 and the limiting column 21. A connecting ring 27 is installed on the side of the first limiting ring 23 away from the limiting push rod 3, and the first limiting ring 23 is rotatably connected to the first limiting ring 23 through the connecting ring 27. A second limiting ring 28 is provided. A plurality of transmission columns 24 are evenly distributed at equal angles on one side of the first limiting ring 23 close to the limiting push rod 3. One end of the transmission column 24 movably passes through the support plate 22. The end of the transmission column 24 close to the limiting push rod 3 is fixedly connected to a fixed block 26. A telescopic spring 25 is provided between the fixed block 26 and the support plate 22. The two ends of the telescopic spring 25 are respectively fixedly connected to the fixed block 26 and the support plate 22, and the telescopic spring 25 is movably sleeved on the outer periphery of the end of the transmission column 24.

[0038] In this embodiment, when the outer periphery of the sealing ring body 45 is cut, the limiting push rod 3 extends and pushes the limiting post 21 connected to the support column 20, so that the outer surface of one end of the limiting post 21 abuts against the outer surface of one end of the filling tube 7. At this time, the side surface of the second limiting ring 28 abuts against the side surface of the first mounting ring 44. Subsequently, under the push of the pushing ring 8, the first mounting ring 44 and the installed sealing ring body 45 move to the limiting post 21, and the first mounting ring 44 pushes the second limiting ring 28, and then pushes each transmission column 24 through the first limiting ring 23. The transmission column 24 is forced to move toward the limiting push rod 3, stretching the telescopic spring 25, and then the cutting assembly 10 cooperates with the rotation of the filling tube 7 to seal the ring body 45. The outer periphery of the driving column 24 is cut. After the cutting is completed, the limiting push rod 3 contracts, and the transmission column 24 moves in the direction of the limiting push rod 3, so that a gap is generated between the driving column 24 and the filling cylinder 7. At the same time, under the elastic force of the telescopic spring 25, the driving column 24 pushes the first limiting ring 23, and pushes the first mounting ring 44 to move to the gap between the driving column 24 and the filling cylinder 7 through the second limiting ring 28. When the gap between the driving column 24 and the filling cylinder 7 is greater than the thickness of the mounting ring 44 and the sealing ring body 45, the suspended mounting ring 44 falls with the processed sealing ring body 45, thereby completing one processing, and repeating the above steps to process the second, third and several sealing ring bodies 45, thereby realizing continuous cutting processing.

[0039] The outer surfaces of the containing cylinder 7 and the limiting column 21 are fixedly connected with a number of limiting strips 18 uniformly distributed at equal angles. The inner circumference of the mounting ring 44 is provided with a limiting groove 46 which corresponds to the limiting strip 18 and is slidably connected. The limiting column 21 is fixedly connected with a number of limiting blocks 29 in the middle of the end face near the containing cylinder 7. The middle of the end face of the containing cylinder 7 near the limiting column 21 is provided with a clamping groove which corresponds to the limiting block 29 in a one-to-one manner. When the first motor 13 rotates the second mounting box 6 and drives the containing cylinder 7 to rotate, the limiting block 29 is engaged with the clamping groove, so that the containing cylinder 7 drives the limiting column 21, and the limiting column 21 is connected to the support column 20 through rotation, and the second limiting ring 28 is connected to the connecting ring 27 through rotation, thereby reducing the resistance during rotation and improving the stability of the sealing ring body 45 during the cutting process.

[0040] The cutting assembly 10 includes a support vertical rod 30, which is fixedly connected to the lower part of the telescopic end of the limit push rod 3. Both sides of the lower end of the support vertical rod 30 are fixedly connected to two parallel support cross bars 31. A limit sleeve 32 is movably sleeved on the support cross bar 31. The limit sleeve 32 is fixedly connected to a positioning block 33 on the side close to the limit push rod 3. A positioning bolt 34 is threaded through the middle part of the positioning block 33. The end of the positioning bolt 34 abuts against the support cross bar 31. The limit sleeve An adjusting cross bar 35 is fixedly connected to the side of the support cross bar 32 away from the limiting push rod 3, and a supporting column 36 is installed on the supporting cross bar 31 through the adjusting cross bar 35. A limiting bolt that abuts against the adjusting cross bar 35 is threaded through the supporting column 36. A cutting push rod 37 is fixedly installed on the upper end of the supporting column 36. The cutting push rod 37 and the axis of the limiting push rod 3 are perpendicular to each other. A mounting seat 38 is installed on the telescopic end of the cutting push rod 37, and a cutting head 39 is installed on the mounting seat 38.

[0041] The cam 36 is then moved back and forth to allow the cam 36 to move freely, and the cam 36 is moved back and forth to allow the cam 36 to move freely, so that the cam 36 can move freely, and the cam 36 can move freely.

[0042] A suction filter 11 is provided on the working platform 1 and below the limit push rod 3. A discharge trolley 12 is provided on the working platform 1 and on one side of the suction filter 11. A bellows 42 is movably provided on the support column 36 and on both sides of the cutting push rod 37. Mounting brackets 40 for fixing the bellows 42 are installed on both sides of the mounting seat 38. An air guide hood 41 is installed at one end of the bellows 42 close to the cutting head 39. An air guide pipe 43 is passed through the other end of the bellows 42, and the bellows 42 is communicated with the suction port of the suction filter 11 through the air guide pipe 43.

[0043] In this embodiment, when the cutting head 39 and the sealing ring body 45 are cutting, the suction filter 11 continuously sucks, forming a negative pressure in the air guide pipe 43, the bellows 42 and the air guide cover 41. The negative pressure of the air guide cover 41 absorbs the particles and dust generated by cutting, and transmits them to the suction filter 11 through the bellows 42 and the air guide pipe 43, thereby reducing pollutants in the air and improving the processing environment. Through the elasticity of the bellows 42 and the sliding connection with the support column 36, the air guide cover 41 moves with the movement of the cutting head 39 under the support of the mounting seat 38 and the mounting frame 40, so as to maintain the absorption efficiency.

[0044] After the cylinder 7 is in operation, the limit push rod 3 is retracted, and the limit assembly 9 and the cutting assembly 10 are away from the filling barrel 7. Then the rotary cylinder 4 is rotated by a set angle. In this embodiment, the rotation is set to ninety degrees, which is convenient for the staff to install several installation rings 44 with interference fit and sealing ring bodies 45 on the filling barrel 7, and make adjacent installation rings 44 abut against each other, so that as many sealing ring bodies 45 as possible can be processed in the same batch of processing. Then the rotary cylinder 4 is returned to its position, and under the lifting and lowering adjustment of the lifting push rod 2, the filling barrel 7 and the limit push rod 3 are coaxial. Then the limit push rod 3 pushes the limit assembly 9 to dock with the filling barrel 7, and then moves the pushing ring 8, and pushes the installing ring 44 toward the limit assembly 9 in turn. The transmission screw 15 is rotated by the second motor 14 to push the transmission ring 19 to move. The transmission ring 19 moves the pushing ring 8 through the transmission block 17, so that the pushing ring 8 can be used to push the sealing ring 45 in turn. The mounting ring 44 is pushed onto the limit assembly 9, and at the same time, the second mounting box 6 is rotated by the first motor 13, and the filling cylinder 7 is rotated, thereby driving the mounting ring 44 and the sealing ring body 45, and processing the peripheral burrs of the sealing ring body 45 through the cutting assembly 10. After the processing is completed, the limit push rod 3 contracts and moves the limit assembly 9, so that the suspended mounting ring 44 falls with the processed sealing ring body 45, and then repeatedly docks the limit assembly 9 with the filling cylinder 7. When the first motor 13 rotates the second mounting box 6 and drives the filling cylinder 7 to rotate, the limit block 29 is correspondingly engaged with the clamping groove, so that the filling cylinder 7 drives the limit column 21, which is connected to the support column 20 through the rotation of the limit column 21, and is connected to the connecting ring 27 through the rotation of the second limit ring 28, thereby reducing the resistance during rotation and improving the stability of the sealing ring body 45 during the cutting process, thereby accurately and quickly processing each sealing ring body 45;

[0045] When the periphery of the sealing ring body 45 is cut, the limiting push rod 3 extends and pushes the limiting post 21 connected to the support column 20, so that the outer surface of one end of the limiting post 21 abuts against the outer surface of one end of the containing tube 7. At this time, the side of the second limiting ring 28 abuts against the side of the first mounting ring 44. Then, under the push of the pushing ring 8, the first mounting ring 44 and the installed sealing ring body 45 move to the limiting post 21, and the first mounting ring 44 pushes the second limiting ring 28, and then pushes each transmission column 24 through the first limiting ring 23. The transmission column 24 is forced to move toward the limiting push rod 3, stretching the telescopic spring 25, and then the cutting assembly 10 cooperates with the rotation of the containing tube 7 to the periphery of the sealing ring body 45. Cutting is carried out. After the cutting is completed, the limiting push rod 3 contracts, and the transmission column 24 moves in the direction of the limiting push rod 3, so that a gap is generated between the transmission column 24 and the containing cylinder 7. At the same time, under the elastic force of the telescopic spring 25, the transmission column 24 pushes the first limiting ring 23, and pushes the first mounting ring 44 to move to the gap between the transmission column 24 and the containing cylinder 7 through the second limiting ring 28. When the gap between the transmission column 24 and the containing cylinder 7 is greater than the thickness of the mounting ring 44 and the sealing ring body 45, the suspended mounting ring 44 falls with the processed sealing ring body 45, thereby completing one processing, and repeating the above steps to process the second, third and several sealing ring bodies 45, thereby realizing continuous cutting processing;

[0046] The spacing between the adjusting cross bars 35 on both sides is adjusted according to the diameter of the sealing ring body 45, and the position of the supporting column 36 is adjusted on the adjusting cross bar 35 according to the thickness of the sealing ring body 45. The position of the adjusting cross bar 35 is determined by the contact between the positioning bolt 34 and the supporting cross bar 31, and the position of the supporting column 36 is determined by the limit bolt, so that the cutting push rod 37 and the sealing ring body 45 are coplanar, and the cutting head 39 is accurately pushed by the cutting push rod 37, so that the cutting head 39 accurately and fully cuts the outer periphery of the sealing ring body 45. When the processing of the current sealing ring body 45 is completed, the cutting push rod 37 is contracted, so that the spacing between the cutting heads 39 is greater than the diameter of the sealing ring body 45, which facilitates the sealing ring body 45 to fall as the mounting ring 44 falls in the air, and then repeats. The telescopic cutting push rod 37 can quickly and accurately process the sealing ring body 45 and can adapt to sealing ring bodies 45 of different diameters and thicknesses. When the cutting head 39 and the sealing ring body 45 are cutting, the suction filter 11 continuously sucks, forming a negative pressure in the air duct 43, the bellows 42 and the air guide cover 41. The negative pressure of the air guide cover 41 absorbs the particles and dust generated by cutting, and transmits them to the suction filter 11 through the bellows 42 and the air duct 43, thereby reducing pollutants in the air and improving the processing environment. Through the telescopic nature of the bellows 42 and the sliding connection with the support column 36, the air guide cover 41 moves with the movement of the cutting head 39 under the support of the mounting seat 38 and the mounting frame 40, so as to maintain the absorption efficiency.
