Description

Technical Field

[0001] This application relates to the field of oil seal production equipment, and in particular to an automatic oil seal cutting device. Background Technology

[0002] An oil seal is a mechanical component used to seal oil. It isolates the lubricated parts in the transmission system from the output parts to prevent lubricating oil leakage.

[0003] Reference Figure 1 After being processed and shaped by molds and other equipment, the oil seal is formed into a semi-finished oil seal 6. The semi-finished oil seal 6 includes an oil seal body 61, which includes an annular inner edge 611 and an outer edge 612. The top ends of the inner edge 611 and the outer edge 612 are connected by a connecting part 613. The outer bottom end of the inner edge 611 and the inner bottom end of the outer edge 612 form a positioning opening 614. The inner bottom end of the inner edge 611 is provided with a first flash 62, and the outer bottom end of the outer edge 612 is provided with a second flash 63. However, the final finished oil seal does not include the first flash 62 and the second flash 63, so trimming is required. The traditional trimming method involves manually trimming the first flash 62 and the second flash 63.

[0004] Regarding the above-mentioned technical solutions, the inventors believe that manual pruning is labor-intensive, labor-intensive, and inefficient. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides an automatic oil seal cutting device.

[0006] This application provides an automatic oil seal cutting device, which adopts the following technical solution:

[0007] An automatic oil seal cutting device includes a worktable with a fixture base. The fixture base has a positioning ring adapted to a positioning opening, and the positioning ring is coaxially arranged with the fixture base. The worktable is equipped with a drive motor for driving the fixture base to rotate. The worktable also has a first cutter bar and a first telescopic mechanism for driving the first cutter bar to move toward the connection between the inner edge and the first flash. The worktable further has a second cutter bar and a second telescopic mechanism for driving the second cutter bar to move toward the connection between the outer edge and the second flash.

[0008] By adopting the above technical solution, after the oil seal semi-finished product is installed on the tooling base, the first telescopic mechanism drives the first cutter bar to move towards the connection between the inner edge and the first flash, and the second telescopic mechanism drives the second cutter bar to move towards the connection between the outer edge and the second flash. Simultaneously, the drive motor rotates, causing the rotating table to rotate, which in turn causes the tooling base to rotate, which in turn causes the positioning ring to rotate, and the positioning ring to rotate the oil seal semi-finished product. During the oil seal semi-finishing process, the first and second cutter bars continue to feed, thereby trimming the first and second flash. Trimming the first and second flash using the first and second cutter bars improves the automation level of trimming, reduces labor intensity, and increases work efficiency.

[0009] Optionally, a rotating platform is rotatably connected to the workbench, the tooling base is disposed on the rotating platform, the output end of the drive motor is coaxially fixed with the rotating platform, an air chamber is formed between the bottom opening of the tooling base and the rotating platform, an outer shell is provided on the workbench, the outer shell is fitted on the outside of the drive motor, the top end of the outer shell abuts against the bottom end of the rotating platform, a vent is provided on the rotating platform, the vent is connected to the inside of the outer shell, a vacuum generator is provided on the workbench, the air inlet of the vacuum generator is connected to an air source, the vacuum port of the vacuum generator is connected to the outer shell, an exhaust control valve is provided at the exhaust port of the vacuum generator, and a first through hole is provided on the tooling base, one end of the first through hole is located within the inner circle of the positioning ring and is connected to the top end of the tooling base, and the other end is connected to the air chamber.

[0010] By adopting the above technical solution, during the trimming of the oil seal semi-finished product, the exhaust control valve is opened, and the air source is introduced into the vacuum generator and discharged from the exhaust port of the vacuum generator. The vacuum port of the vacuum generator generates negative pressure, which in turn generates negative pressure inside the outer shell and the air chamber, thereby tightly adhering the oil seal semi-finished product to the tooling base. This reduces the possibility of the oil seal semi-finished product detaching or moving up and down during the rotation of the tooling base, thus ensuring the trimming accuracy of the first and second flashes. After the oil seal semi-finished product is trimmed, the exhaust control valve is closed, and the air source is introduced into the vacuum generator and discharged from the vacuum port of the vacuum generator, thereby venting the air from the inside of the outer shell and the air chamber. By blowing air through the first through hole, the first flash can be blown out of the tooling base, making it easier for the first flash to detach from the inner edge.

[0011] Optionally, the top end of the positioning ring is provided with a second through hole, which is connected to the air chamber. Multiple second through holes are evenly arranged along the circumference of the positioning ring. The tooling base is provided with a first control valve for controlling the opening and closing of the first through hole and a second control valve for controlling the opening and closing of the second through hole.

[0012] By adopting the above technical solution, during the trimming process of the oil seal semi-finished product, the first control valve and the second control valve are opened, the exhaust control valve is opened, and after the air source is introduced into the vacuum generator, a negative pressure is generated at the vacuum port of the vacuum generator, which tightly sucks the oil seal semi-finished product onto the tooling base; when the oil seal semi-finished product is trimmed, the first control valve is opened, the second control valve is closed, the exhaust control valve is closed, and after the air source is introduced into the vacuum generator, the first flash is blown away from the tooling base; when the first control valve is closed, the second control valve is opened, and the exhaust control valve is closed, after the air source is introduced into the vacuum generator, it is discharged from the vacuum port of the vacuum generator, thereby venting the interior of the outer shell and the air chamber, and blowing air through the second through hole, the final oil seal finished product can be blown up.

[0013] Optionally, a mounting frame is provided on one side of the workbench, and a suction pipe is provided on the mounting frame with the inlet of the suction pipe facing downward. A first drive source is provided on the mounting frame to drive the suction pipe to move toward the positioning ring. A material suction machine is provided on the mounting frame. A connecting hose is provided at the end of the suction pipe away from the tooling base. The end of the connecting hose away from the suction pipe is connected to the input end of the material suction machine. A discharge pipe is provided at the output end of the material suction machine.

[0014] By adopting the above technical solution, after the oil seal semi-finished product is trimmed, the first drive source drives the suction pipe to move toward the positioning ring. When the pipe opening is directly above the positioning ring, the suction machine starts and sucks up the blown oil seal finished product through the suction pipe, and finally discharges it from the discharge pipe, thus realizing the centralized collection of oil seal finished products.

[0015] Optionally, it also includes a feeding mechanism, which includes a spiral vibratory feeder and a conveyor belt. The outlet of the spiral vibratory feeder is connected to the feed end of the conveyor belt. The discharge end of the conveyor belt is provided with a material picking position. The material picking position is located on the side of the workbench away from the mounting frame. The mounting frame is provided with a feeding component for installing the oil seal semi-finished product at the material picking position onto the positioning ring.

[0016] By adopting the above technical solution, through the setting of spiral vibratory feeder, conveyor belt and feeding components, the oil seal semi-finished products in spiral vibratory feeder can be transported to the positioning ring, realizing the automation of oil seal semi-finished product feeding, further improving the automation level of product trimming, and by replacing manual feeding with machines, the labor intensity is further reduced and the work efficiency is improved.

[0017] Optionally, the feeding assembly includes a movable plate and a feeding cylinder disposed on the movable plate. The movable plate is slidably connected to the mounting frame. The mounting frame is provided with a second driving source that drives the movable plate to move along the line connecting the material picking position and the center of the positioning ring. The output end of the feeding cylinder is provided with a suction component for picking up the oil seal semi-finished product.

[0018] By adopting the above technical solution, when the oil seal semi-finished product is picked up at the picking position, the second drive source drives the moving plate to move, so that the feeding cylinder is directly above the picking position. Then the feeding cylinder is started, which drives the suction component to move downward. Then the suction component picks up the oil seal semi-finished product. The second drive source can drive the feeding cylinder from the picking position to directly above the tooling base. Then the feeding cylinder is started, which drives the suction block to move downward, which can press the positioning ring into the positioning opening, thereby realizing the positioning and installation of the oil seal semi-finished product.

[0019] Optionally, the suction component includes a suction block, the bottom end of which is provided with a limiting end adapted to the inner edge, the bottom end of which is provided with an air suction hole, the top end of which is provided with a connecting groove, the air suction hole communicating with the connecting groove, a connecting cylinder inserted into the connecting groove, the opening of the connecting cylinder facing downwards, the top end of the connecting cylinder being fixedly connected to the output end of the feeding cylinder, the suction block being provided with a connecting air pipe, the side wall of the suction block being provided with an insertion hole for inserting the connecting air pipe, one end of the connecting air pipe passing through the insertion hole and extending into the interior of the connecting cylinder, the other end being connected to a suction pump, and the side wall of the connecting cylinder being provided with an opening for the connecting air pipe to pass through.

[0020] By adopting the above technical solution, when the oil seal semi-finished product is being picked up at the material picking position, the feeding cylinder is located directly above the material picking position. Then the feeding cylinder is started, which drives the suction block to move downward until the bottom end of the limit end is close to the first flash. Then the air pump is used to draw air, which can achieve the purpose of picking up the oil seal semi-finished product.

[0021] Optionally, the end of the connecting air tube away from the suction pump is provided with a flexible air nozzle. The flexible air nozzle is tapered in the direction away from the suction pump. The diameter of the insertion hole and the opening is larger than the diameter of the small end of the flexible air nozzle, and the diameter of the opening is smaller than the diameter of the large end of the flexible air nozzle. A locking nut is threaded onto the circumferential sidewall of the connecting air tube. The locking nut abuts against the sidewall of the suction block, and the large end of the flexible air nozzle abuts against the inner sidewall of the connecting cylinder.

[0022] By adopting the above technical solution, when installing the connecting air tube, first insert the connecting cylinder into the connecting groove, and align the insertion hole with the opening. Then, insert the small end of the elastic nozzle into the insertion hole and gradually push it inward. The elastic nozzle deforms, and the large end is also squeezed into the insertion hole. Continue to push the connecting air tube so that the elastic nozzle enters the connecting cylinder through the opening. After the elastic nozzle passes through the opening, it returns to its original shape. Then, tighten the locking bolt until it presses against the suction block. At this time, the large end of the elastic nozzle simultaneously abuts against the inner wall of the connecting cylinder. Since the elastic nozzle is elastic, it can fit tightly against the connecting cylinder, thereby ensuring the airtightness between the connecting air tube and the internal space of the connecting cylinder.

[0023] Optionally, the spiral vibratory feeder includes a disc body, the disc body is provided with a spiral rising material channel, the inner side of the spiral rising material channel is provided with a sorting notch, and the side wall of the disc body is provided with a clearance groove for the second flash to pass through, the clearance groove and the sorting notch are positioned correspondingly.

[0024] By adopting the above technical solution, when the spiral vibratory feeder is started, the oil seal semi-finished product in the feeder moves along the spiral rising material channel. When the oil seal semi-finished product passes through the sorting notch, there are two situations: if the positioning opening is downward, the first flash protrudes through the clearance groove, and the outer side of the outer edge moves along the inner side wall of the feeder. Most of the area of ​​the first flash protrudes is located on the spiral rising material channel, and the oil seal semi-finished product can pass through the sorting notch; if the positioning opening is upward, the outer side of the second flash protrudes along the inner side wall of the feeder, the side with the smaller connecting area moves along the outer side of the spiral rising material channel, while the other side with the larger connecting area is suspended at the sorting notch. This is equivalent to the oil seal semi-finished product stepping into the void on one side when passing through the sorting notch, causing the center of gravity to become unbalanced. The oil seal semi-finished product falls onto the spiral rising material channel below. When it falls, the oil seal semi-finished product flips over, achieving the effect of automatically identifying the front and back sides.

[0025] Optionally, conveyor frames are provided on both sides of the conveyor belt in the width direction. The conveyor belt is mounted on the conveyor frames, and several guide components are provided on the conveyor frames. The guide components on two conveyor frames are staggered. Each guide component includes a guide rope and an adjusting rod. The head of the adjusting rod is located above the conveyor belt, and the tail of the adjusting rod has a threaded section. A threaded sleeve is provided on the conveyor frame, and the threaded section is threadedly connected to the threaded sleeve. A handle is provided at the end of the threaded section away from the adjusting rod. A connector is movably fitted on the head of the adjusting rod. One end of the guide rope is fixed to the connector, and the other end is provided with a winding reel. The winding reel is rotatably connected to the conveyor frame and located on the side of the adjusting rod near the feed end of the conveyor belt. A rotating shaft is coaxially fixed on the winding reel, and a coil spring is fitted on the rotating shaft. One end of the coil spring is fixed to the rotating shaft, and the other end is fixed to the conveyor frame.

[0026] By adopting the above technical solution, when the oil seal semi-finished product is conveyed by the conveyor belt, the guide rope can correct and guide the path of the oil seal semi-finished product, reducing the possibility of the oil seal semi-finished product deviating from the picking position. Furthermore, the angle between the guide rope and the conveyor frame can be adjusted according to the actual size of the oil seal semi-finished product, thereby improving the accuracy of reaching the picking position. When adjusting the angle between the guide rope and the conveyor frame, turning the handle rotates the threaded section, which in turn moves the adjusting rod along its own axis. The adjusting rod then moves the connecting head along the axis of the adjusting rod, thus achieving the purpose of adjusting the angle between the guide rope and the conveyor frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a first cutter bar, a second cutter bar, and a fixture base, the oil seal semi-finished product is installed on the fixture base. A first telescopic mechanism drives the first cutter bar to move towards the connection point between the inner edge and the first flash, and a second telescopic mechanism drives the second cutter bar to move towards the connection point between the outer edge and the second flash. Simultaneously, a drive motor rotates, causing the rotating table to rotate. The rotating table rotates, causing the fixture base to rotate, which in turn rotates the positioning ring. The positioning ring rotates, causing the oil seal semi-finished product to rotate. During the oil seal semi-finishing process, the first and second cutter bars continue to feed, thereby trimming the first and second flash. Using the first and second cutter bars to trim the first and second flash improves the automation level of trimming, reduces labor intensity, and increases work efficiency.

[0029] 2. Through the first through hole and the vacuum generator, during the trimming of the oil seal semi-finished product, the exhaust control valve is opened, and the air source is introduced into the vacuum generator and discharged from the exhaust port of the vacuum generator. The vacuum port of the vacuum generator generates negative pressure, which in turn generates negative pressure inside the outer shell and the air chamber, thereby tightly adhering the oil seal semi-finished product to the tooling base, reducing the possibility of the oil seal semi-finished product detaching or moving up and down during the rotation of the tooling base, thus ensuring the trimming accuracy of the first and second flashes; after the oil seal semi-finished product is trimmed, the exhaust control valve is closed, and the air source is introduced into the vacuum generator and discharged from the vacuum port of the vacuum generator, thereby venting the inside of the outer shell and the air chamber. By blowing air through the first through hole, the first flash can be blown out of the tooling base, making it easier for the first flash to detach from the inner edge;

[0030] 3. By setting up a spiral vibratory feeder, conveyor belt, and feeding components, the oil seal semi-finished products in the spiral vibratory feeder can be transported to the positioning ring, realizing the automation of oil seal semi-finished product feeding, further improving the automation level of product trimming, and replacing manual feeding with machines to further reduce labor intensity and improve work efficiency.

[0042] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail below.

[0043] This application discloses an automatic oil seal cutting device. (Refer to...) Figure 2 An automatic oil seal cutting device includes a worktable 1 and a feeding mechanism 2 for transporting semi-finished oil seals 6 onto the worktable 1. The feeding mechanism 2 includes a spiral vibratory feeder 21 and a conveyor belt 22. The outlet of the spiral vibratory feeder 21 is connected to the feed end of the conveyor belt 22, and the discharge end of the conveyor belt 22 is provided with a material pick-up position 221. A mounting frame 3 is provided on the side of the worktable 1 away from the material pick-up position 221. A feeding assembly 23 is provided on the mounting frame 3, which can transport the semi-finished oil seals 6 at the material pick-up position 221 onto the worktable 1.

[0044] Reference Figure 1 and Figure 3 The spiral vibratory feeder 21 includes a feeder body 211, and a spiral rising channel 212 is installed inside the feeder body 211. The spiral rising channel 212 is inclined downward in the direction from the inside to the outside. A sorting notch 2121 is opened on the inner side of the spiral rising channel 212. A clearance groove 2111 is opened on the side wall of the feeder body 211 for the second flash 63 to pass through. The clearance groove 2111 and the sorting notch 2121 are positioned correspondingly. When the spiral vibratory feeder 21 is started, the oil seal semi-finished product 6 inside the feeder body 211 moves along the spiral rising channel 212. When the oil seal semi-finished product 6 passes through the sorting notch 2121, there are two situations: if the positioning opening 614 faces downward, the first flash 62 passes through the clearance groove 2111, and the outer side wall of the outer edge 612 moves along the inner side wall of the feeder body 211. Most of the area of ​​the first flash 62 is located on the spiral rising channel 212, and the oil seal semi-finished product 6 can pass through the sorting notch 2121; if the positioning opening 614 faces upward, the outer side of the second flash 63 moves along the inner side wall of the feeder body 211. As the inner wall of the disc 211 moves, the smaller side of the connecting part 613 moves along the outer side of the spiral rising material channel 212, while the larger side of the connecting part 613 is suspended at the sorting notch 2121. This is equivalent to the oil seal semi-finished product 6 losing its balance when it steps into the sorting notch 2121, causing it to fall onto the spiral rising material channel 212 below. During the fall, the oil seal semi-finished product 6 flips over, ensuring that the oil seal semi-finished product 6 output from the spiral vibrating disc 21 outlet is always positioned with the positioning opening 614 facing downwards.

[0045] Reference Figure 2 , Figure 4 and Figure 5Conveyor frames 222 are provided on both sides of the conveyor belt 22 in the width direction. The conveyor belt 22 is mounted on the conveyor frames 222. Several guide components 4 are provided on the conveyor frames 222. The guide components 4 on the two conveyor frames 222 are staggered. The guide components 4 include guide ropes 41 and adjusting rods 42. The head of the adjusting rod 42 is located above the conveyor belt 22. A threaded section 421 is coaxially fixed to the tail of the adjusting rod 42. A threaded sleeve 2221 is fixed on the conveyor frame 222. The threaded section 421 is threadedly connected to the threaded sleeve 2221. A handle 4211 is fixed to the end of the threaded section 421 away from the adjusting rod 42. A connector 422 is sleeved on the outer side of the head of the adjusting rod 42. The connector 422 is rotatably connected to the adjusting rod 42. The outer surface of the connector 422 is spherical. A winding reel 43 is rotatably connected to the conveyor frame 222. The winding reel 43 is located on the side of the adjusting rod 42 near the feed end of the conveyor belt 22. One end of the guide rope 41 is fixed to the end of the connector 422 away from the adjusting rod 42, and the other end is wound on the winding reel 43. A rotating shaft 431 is coaxially fixed to the lower end of the winding reel 43. A coil spring 4311 is sleeved on the rotating shaft 431. One end of the coil spring 4311 is fixed to the rotating shaft 431, and the other end is fixed to the conveyor frame 222.

[0046] When the semi-finished oil seal 6 is conveyed by the conveyor belt 22, the guide rope 41 can correct and guide the path of the semi-finished oil seal 6, reducing the possibility that the semi-finished oil seal 6 will deviate from the picking position 221. Furthermore, the angle between the guide rope 41 and the conveyor frame 222 can be adjusted according to the actual size of the semi-finished oil seal 6, thereby improving the accuracy of reaching the picking position 221. When adjusting the angle between the guide rope 41 and the conveyor frame 222, the handle 4211 is turned, causing the threaded section 421 to rotate. The rotation of the threaded section 421 causes the adjusting rod 42 to move along its own axial direction. The adjusting rod 42 causes the connector 422 to move along the axial direction of the adjusting rod 42, thereby achieving the purpose of adjusting the angle between the guide rope 41 and the conveyor frame 222. During the adjustment process, the coil spring 4311 ensures that the guide rope 41 remains taut.

[0047] Reference Figure 1 , Figure 6 and Figure 7The worktable 1 is equipped with a rotating platform 11 and a drive motor 111 for rotating the platform 11. The output end of the drive motor 111 is coaxially fixed to the bottom end of the rotating platform 11. A tooling base 12 is mounted on the rotating platform 11 and is fixedly connected to the platform 11 by bolts 121. A positioning ring 122 is coaxially fixed to the top end of the tooling base 12, and the positioning ring 122 is adapted to the positioning opening 614. The worktable 1 is equipped with a first tool bar 13 and a first telescopic mechanism 14 for driving the first tool bar 13 to move toward the connection between the inner edge 611 and the first flash 62. The worktable 1 is also equipped with a second tool bar 15 and a second telescopic mechanism 16 for driving the second tool bar 15 to move toward the connection between the outer edge 612 and the second flash 63.

[0048] Reference Figure 1 , Figure 6 and Figure 7 The feeding assembly 23 includes a movable plate 231 and a feeding cylinder 232 fixed on the movable plate 231. The movable plate 231 is slidably connected to the mounting frame 3. A second drive source 31 is fixed on the mounting frame 3 to drive the movable plate 231 to move along the line connecting the center of the picking position 221 and the positioning ring 122. The output end of the feeding cylinder 232 is provided with a suction component 5 for sucking up the oil seal semi-finished product 6. In this embodiment, the second drive source 31 is a cylinder.

[0049] Reference Figure 6 and Figure 8 The suction component 5 includes a suction block 51, the bottom end of which is integrally formed with a limiting end 52 that matches the inner edge 611. The bottom end of the limiting end 52 has a suction hole 521, and the top end of the suction block 51 has a connecting groove 511, which communicates with the suction hole 521. A connecting cylinder 53 is inserted into the connecting groove 511, with its opening facing downwards. The top end of the connecting cylinder 53 is fixedly connected to the output end of the feeding cylinder 232. A connecting air pipe 54 is installed on the suction block 51. An insertion hole 512 for inserting the connecting air pipe 54 is provided on the side wall of the suction block 51. One end of the connecting air pipe 54 passes through the insertion hole 512 and extends into the interior of the connecting cylinder 53, while the other end is connected to a suction pump 55. An opening 531 for the connecting air pipe 54 to pass through is provided on the side wall of the connecting cylinder 53.

[0050] When the oil seal semi-finished product 6 is picked up from the picking position 221, the second drive source 31 drives the moving plate 231 to move, so that the loading cylinder 232 is directly above the picking position 221. Then the loading cylinder 232 is started, driving the suction block 51 to move downward until the bottom end of the limiting end 52 is close to the first flash 62. Then the vacuum pump 55 pumps air to achieve the purpose of picking up the oil seal semi-finished product 6. Then the second drive source 31 is started, which can drive the loading cylinder 232 from the picking position 221 to directly above the tooling base 12. Then the loading cylinder 232 is started, driving the suction block 51 to move downward until the positioning ring 122 is pressed into the positioning opening 614. Finally, the vacuum pump 55 stops, the loading cylinder 232 drives the suction block 51 to move upward, the oil seal semi-finished product 6 is separated from the limiting end 52 and installed on the tooling base 12, and the loading cylinder 232 returns to the picking position 221 to pick up the next oil seal semi-finished product 6.

[0051] After the oil seal semi-finished product 6 is installed on the tooling base 12, the first telescopic mechanism 14 drives the first cutter bar 13 to move toward the connection between the inner edge 611 and the first flash 62, and the second telescopic mechanism 16 drives the second cutter bar 15 to move toward the connection between the outer edge 612 and the second flash 63. At the same time, the drive motor 111 rotates, which drives the rotating table 11 to rotate. The rotating table 11 rotates, which drives the tooling base 12 to rotate. The rotating tooling base 12 rotates, which drives the positioning ring 122 to rotate. The positioning ring 122 rotates, which drives the oil seal semi-finished product 6 to rotate. During the process of the oil seal semi-finished product 6, the first cutter bar 13 and the second cutter bar 15 continue to feed, thereby realizing the trimming of the first flash 62 and the second flash 63.

[0052] Reference Figure 8 To facilitate the installation of the connecting air pipe 54 and ensure airtightness between the connecting air pipe 54 and the internal space of the connecting cylinder 53, a flexible air nozzle 541 is fixedly connected to the end of the connecting air pipe 54 away from the suction pump 55. The flexible air nozzle 541 is tapered away from the suction pump 55, with the diameter of the insertion hole 512 and the opening 531 being larger than the diameter of the small end of the flexible air nozzle 541, and the diameter of the opening 531 being smaller than the diameter of the large end of the flexible air nozzle 541. A locking nut 542 is threaded onto the circumferential sidewall of the connecting air pipe 54, abutting against the sidewall of the suction block 51, and the large end of the flexible air nozzle 541 abutting against the inner sidewall of the connecting cylinder 53. In this embodiment, the flexible air nozzle 541 is made of rubber.

[0053] When installing the connecting air tube 54, first insert the connecting cylinder 53 into the connecting groove 511, and align the insertion hole 512 with the opening 531. Then, insert the small end of the elastic nozzle 541 into the insertion hole 512 and gradually push it inward. The elastic nozzle 541 deforms, and the large end is also squeezed into the insertion hole 512. Continue to push the connecting air tube 54 so that the elastic nozzle 541 passes through the opening 531 and enters the connecting cylinder 53. After passing through the opening 531, the elastic nozzle 541 returns to its original shape. Then, tighten the locking bolt 121 until the locking bolt 121 abuts against the suction block 51. At this time, the large end of the elastic nozzle 541 abuts against the inner wall of the connecting cylinder 53. Since the elastic nozzle 541 is elastic, it can fit tightly against the connecting cylinder 53, thereby ensuring the airtightness between the connecting air tube 54 and the internal space of the connecting cylinder 53.

[0054] Reference Figure 7 and Figure 9 An air chamber 123 is formed between the bottom opening of the tooling base 12 and the rotating table 11. An outer shell 17 is fixed on the worktable 1, and the outer shell 17 is fitted onto the outside of the drive motor 111. The top of the outer shell 17 abuts against the bottom of the rotating table 11. A vent hole 112 is provided on the rotating table 11, and the vent hole 112 communicates with the interior of the outer shell 17. A vacuum generator 18 is installed on the worktable 1. The air inlet of the vacuum generator 18 is connected to an air source 181. The vacuum port of the vacuum generator 18 is connected to the outer shell 17. An exhaust control valve 182 is installed at the exhaust port of the vacuum generator 18. A first through hole 124 is provided on the tooling base 12. One end of the first through hole 124 is located within the inner circle of the positioning ring 122 and communicates with the top of the tooling base 12. The other end communicates with the air chamber 123. In this embodiment, the air source 181 is an air compressor.

[0055] Reference Figure 1 The positioning ring 122 has a second through hole 1221 at its top end, which communicates with the air chamber 123. Multiple second through holes 1221 are evenly distributed along the circumference of the positioning ring 122. A first control valve 125, which controls the opening and closing of the first through hole 124, and a second control valve 126, which controls the opening and closing of the second through hole 1221, are mounted on the tooling base 12. Both the first control valve 125 and the second control valve 126 are located within the air chamber 123. In this embodiment, both the first control valve 125 and the second control valve 126 are wireless miniature solenoid valves.

[0056] During the trimming process of the oil seal semi-finished product 6, the first control valve 125 and the second control valve 126 are opened, the exhaust control valve 182 is opened, the air source 181 is introduced into the vacuum generator 18 and discharged from the exhaust port of the vacuum generator 18. The vacuum port of the vacuum generator 18 generates negative pressure, thereby generating negative pressure inside the outer shell 17 and the air chamber 123, thereby tightly adhering the oil seal semi-finished product 6 to the tooling base 12, reducing the possibility of the oil seal semi-finished product 6 detaching or moving up and down during the rotation of the tooling base 12, thus ensuring the trimming accuracy of the first flash 62 and the second flash 63.

[0057] After the oil seal semi-finished product 6 is trimmed, the first control valve 125 is opened, the second control valve 126 is closed, the exhaust controller valve is closed, the air source 181 is introduced into the vacuum generator 18, and the air is discharged from the vacuum port of the vacuum generator 18, thereby venting the interior of the outer shell 17 and the air chamber 123. Air is blown through the first through hole 124, which can blow the first flash 62 out of the tooling base 12, so that the first flash 62 is separated from the inner edge 611, and the blown first flash 62 is deviated from the center of the tooling base 12.

[0058] Reference Figure 9 To reduce the whistling sound of gas exhaust from the exhaust port of the vacuum generator 18, a silencer 1821 is fixedly connected to the end of the exhaust control valve 182 away from the vacuum generator 18. To reduce the possibility of air leakage between the top of the outer casing 17 and the bottom of the rotating platform 11 during rotation, a sealing gasket 171 is fixed to the top of the outer casing 17. In this embodiment, the sealing gasket 171 is made of nitrile rubber.

[0059] Reference Figure 6 , Figure 7 and Figure 10 The mounting frame 3 is equipped with a suction pipe 32 and a first drive source 33 that drives the suction pipe 32 to move toward the positioning ring 122. The opening of the suction pipe 32 is oriented downwards. A material suction machine 34 is mounted on the mounting frame 3. The end of the suction pipe 32 away from the tooling base 12 is connected to a connecting hose 321. The end of the connecting hose 321 away from the suction pipe 32 is connected to the input end of the material suction machine 34. The output end of the material suction machine 34 is connected to a discharge pipe 341. In this embodiment, the first drive source 33 is a cylinder, and the connecting hose 321 is a corrugated pipe.

[0060] When the first flash 62 and the second flash 63 deviate from the center of the tooling base 12, the first drive source 33 drives the suction pipe 32 to move toward the positioning ring 122. When the pipe opening of the suction pipe 32 is directly above the positioning ring 122, the first control valve 125 closes, the second control valve 126 opens, the exhaust controller valve closes, the air source 181 enters the vacuum generator 18 and is discharged from the vacuum port of the vacuum generator 18, thereby venting the interior of the outer shell 17 and the air chamber 123. Air is blown through the second through hole 1221, which can blow up the final oil seal product. At the same time, the suction machine 34 starts and sucks up the blown oil seal product through the suction pipe 32, and finally discharges it from the discharge pipe 341, realizing the centralized collection of the oil seal product.

[0061] The implementation principle of the automatic oil seal cutting device in this application embodiment is as follows: When using the device, the spiral vibratory feeder 21 and the conveyor belt 22 are started. Through the front and back recognition of the spiral vibratory feeder 21, the oil seal semi-finished products 6 arriving at the feeding end of the conveyor belt 22 are all aligned with the positioning opening 614 facing downwards. When the oil seal semi-finished products 6 are conveyed by the conveyor belt 22, the guide rope 41 can correct and guide the path of the oil seal semi-finished products 6, reducing the possibility that the oil seal semi-finished products 6 will eventually deviate from the picking position 221.

[0062] When the oil seal semi-finished product 6 is picked up from the picking position 221, the second drive source 31 drives the moving plate 231 to move, so that the loading cylinder 232 is directly above the picking position 221. Then the loading cylinder 232 is started, driving the suction block 51 to move downward until the bottom end of the limiting end 52 is close to the first flash 62. Then the vacuum pump 55 pumps air to achieve the purpose of picking up the oil seal semi-finished product 6. Then the second drive source 31 is started, which can drive the loading cylinder 232 from the picking position 221 to directly above the tooling base 12. Then the loading cylinder 232 is started, driving the suction block 51 to move downward until the positioning ring 122 is pressed into the positioning opening 614. Finally, the vacuum pump 55 stops, the loading cylinder 232 drives the suction block 51 to move upward, the oil seal semi-finished product 6 is separated from the limiting end 52 and installed on the tooling base 12, and the loading cylinder 232 returns to the picking position 221 to pick up the next oil seal semi-finished product 6.

[0063] After the oil seal semi-finished product 6 is installed on the tooling base 12, the first telescopic mechanism 14 drives the first cutter bar 13 to move toward the connection between the inner edge 611 and the first flash 62, and the second telescopic mechanism 16 drives the second cutter bar 15 to move toward the connection between the outer edge 612 and the second flash 63. At the same time, the drive motor 111 rotates, which drives the rotating table 11 to rotate. The rotating table 11 rotates, which drives the tooling base 12 to rotate. The rotating tooling base 12 rotates, which drives the positioning ring 122 to rotate. The positioning ring 122 rotates, which drives the oil seal semi-finished product 6 to rotate. During the process of the oil seal semi-finished product 6, the first cutter bar 13 and the second cutter bar 15 continue to feed, thereby realizing the trimming of the first flash 62 and the second flash 63.

[0064] During the trimming process of the oil seal semi-finished product 6, the first control valve 125 and the second control valve 126 are opened, the exhaust control valve 182 is opened, the air source 181 is introduced into the vacuum generator 18 and discharged from the exhaust port of the vacuum generator 18. The vacuum port of the vacuum generator 18 generates negative pressure, thereby generating negative pressure inside the outer shell 17 and the air chamber 123, thereby tightly adhering the oil seal semi-finished product 6 to the tooling base 12, reducing the possibility of the oil seal semi-finished product 6 detaching or moving up and down during the rotation of the tooling base 12, thus ensuring the trimming accuracy of the first flash 62 and the second flash 63.

[0065] After the oil seal semi-finished product 6 is trimmed, the first control valve 125 is opened, the second control valve 126 is closed, the exhaust controller valve is closed, the air source 181 is introduced into the vacuum generator 18, and the air is discharged from the vacuum port of the vacuum generator 18, thereby venting the interior of the outer shell 17 and the air chamber 123. Air is blown through the first through hole 124, which can blow the first flash 62 out of the tooling base 12, so that the first flash 62 is separated from the inner edge 611, and the blown first flash 62 is deviated from the center of the tooling base 12.

[0066] Finally, the first drive source 33 drives the suction pipe 32 to move toward the positioning ring 122. When the pipe opening of the suction pipe 32 is directly above the positioning ring 122, the first control valve 125 closes, the second control valve 126 opens, the exhaust controller valve closes, the air source 181 enters the vacuum generator 18 and is discharged from the vacuum port of the vacuum generator 18, thereby venting the interior of the outer casing 17 and the air chamber 123. Air is blown through the second through hole 1221, which can blow up the final oil seal product. At the same time, the suction machine 34 starts and sucks up the blown oil seal product through the suction pipe 32, and finally discharges it from the discharge pipe 341, realizing the centralized collection of the oil seal product.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
