Description

Technical Field

[0001] This invention relates to the field of cutting technology, and more specifically to a high-voltage switch housing port cutting device. Background Technology

[0002] The high-voltage switch housing is a key structure protecting the core components of high-voltage switchgear. Common shapes of high-voltage switch housings include cylindrical tubes. Flanges are installed on cylindrical high-voltage switch housings. The cutting precision of the high-voltage switch housing ports directly affects the equipment's sealing performance and operational stability.

[0003] During the production process, reliable clamping and fixing are the foundation for ensuring cutting accuracy. Existing technologies typically employ customized clamping and fixing devices. Through a precisely adapted mechanical structure, these devices can provide stable support for high-voltage switch housings of specific specifications, effectively suppressing vibration and offset during cutting and meeting standardized production requirements.

[0004] However, as high-voltage switchgear develops towards diversification, miniaturization, and large-scale applications, the differences in equipment specifications have increased significantly. Traditional fixed clamping devices, due to their single-size adaptability design, struggle to flexibly adapt to the clamping requirements of housings of different sizes and diameters. When dealing with smaller high-voltage switchgear housings, the clamping components cannot effectively fit together, easily leading to localized stress concentrations, causing the housing to twist or slide during cutting. For larger housings, the existing devices have insufficient fixing range, making it difficult to generate a uniformly distributed clamping force, resulting in insecure housing fixation. This not only severely affects cutting accuracy, leading to port size deviations, excessive surface roughness, and increased scrap rates, but also prolongs equipment debugging time due to frequent changes in adaptable clamps, significantly increasing production costs and manufacturing cycles. Summary of the Invention

[0005] To address the technical problem that traditional clamping devices for high-voltage switch housings, which employ a single-size adaptability design, are unable to flexibly adapt to the clamping requirements of housings of different sizes and diameters, this invention provides a high-voltage switch housing port cutting device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-voltage switch housing port cutting device includes a base, a fixed frame fixedly connected to the top of the base, a support ring fixedly installed inside the fixed frame, the central axis of the support ring being horizontally oriented, and an adjusting ring coaxially rotatably connected to the outer periphery of the support ring. The end face of the adjusting ring has several grooves of the same shape and size, evenly distributed in an array around the circumference of the adjusting ring. On the radial surface of the adjusting ring, each groove extends obliquely, with both radial and circumferential components in its extension direction. A cylindrical sliding rod is slidably connected within each groove, the outer diameter of which matches the width of the groove, and the axial direction of the sliding rod being parallel to the central axis of the adjusting ring. One end of the sliding rod extends out of the groove and is vertically connected to a cylindrical sliding rod, which slides radially through the outer periphery of the support ring. A cutting assembly is installed inside the fixed frame, including a cutting strip capable of vertically raising and lowering and reciprocating horizontally in a direction perpendicular to the axial direction of the adjusting ring.

[0007] The above structural design provides a stable support foundation with a fixed frame. The internal support ring and coaxially rotating adjusting ring work together. Through the evenly distributed array of grooves on the adjusting ring and the arrangement of slide rod one and slide rod two, slide rod two can slide and extend radially along the adjusting ring (i.e., the support ring), thereby clamping high-voltage switch housings of different diameters within the support ring. This greatly improves the versatility and flexibility of the device. The cutting strip in the cutting assembly can move vertically up and down and horizontally reciprocatingly, enabling it to cut the clamped high-voltage switch housing.

[0008] As a preferred implementation of a high-voltage switch housing port cutting device, one end of the slide rod that slides into the support ring is connected to a clamping block. The clamping block has a shaft-like structure, and its axial direction is parallel to the central axis of the support ring.

[0009] With the above structural design, the clamping block adopts a shaft-shaped structure, and its axis is parallel to the axis of the support ring. When clamping the high-voltage switch housing, it can increase the contact area with the housing, make the clamping force distribution more uniform, avoid damage to the housing caused by local stress concentration, and further improve the stability and reliability of clamping.

[0010] As a preferred implementation of a high-voltage switch housing port cutting device, two support rings and two adjusting rings are provided, and the two support rings and two adjusting rings are coaxially arranged. The cutting component is located between the two support rings. A drive component is fixedly installed on the outside of the fixed frame. The drive component includes a support block, and a double-headed motor is fixedly connected to the middle of the support block. The axial direction of the output shaft of the double-headed motor is parallel to the central axis of the support ring. The output ends of the two output shafts of the double-headed motor are fixedly connected to small pulleys. A large pulley is coaxially fixedly connected to the outer circumference of each support ring. Each small pulley is connected to a large pulley through a synchronous belt. The fixed frame has a notch for the synchronous belt to pass through.

[0011] The above structural design, with its two support rings and adjusting ring, enhances the support strength and stability of the high-voltage switch housing, ensuring that the housing will not wobble due to uneven force during cutting. The dual-head motor in the drive assembly drives the adjusting ring to rotate via a small pulley, a synchronous belt, and a large pulley, achieving automated adjustment of the clamping range. This makes operation more convenient and efficient, reduces labor intensity, and improves production efficiency.

[0012] As a preferred implementation of a high-voltage switch housing port cutting device, the cutting assembly includes a cylinder one, which has two cylinders. The output shaft of the cylinder one is vertically arranged, and the output end of the output shaft of each cylinder one is connected to a cylinder two. The output shafts of the two cylinder two are horizontal and collinear. The output shafts of the cylinder two are perpendicular to the central axis of the support ring, and the two ends of the cutting strip are respectively connected to the output ends of the output shafts of the two cylinder two.

[0013] With the above-mentioned structural design, the two cylinders and the two cylinders work together to precisely control the vertical lifting and horizontal reciprocating sawing action of the cutting bar.

[0014] As a preferred implementation of a high-voltage switch housing port cutting device, the cutting assembly also includes cylinder three, of which there are two. The output shaft of cylinder three is vertically arranged. Cylinder one is connected to the inner top of the fixed frame, and cylinder three is connected to the top of the base. The output end of the output shaft of each cylinder three is connected to a cylinder two.

[0015] The above structural design further enhances the stability and adjustability of the cutting assembly.

[0016] In a preferred embodiment of a high-voltage switch housing port cutting device, both ends of the cutting strip have slots. A connecting block is fixedly connected to the output end of the output shaft of cylinder two. A limit plate is fixedly connected inside the connecting block. The plate surface of the limit plate is horizontally set with the output shaft of cylinder two. Compression springs are vertically connected to both sides of the limit plate. A lever is connected to the end of the compression spring away from the limit plate. The lever can slide in the connecting block along the axial direction of the compression spring. The connecting block has a slot along the axial direction of the compression spring. One side of the lever extends out from the slot. A locking block is connected to the side of the lever away from the compression spring. The locking block protrudes from the connecting block and engages with the slot.

[0017] The above structural design, with its end slots engaging with the limiting plate, compression spring, lever, and locking block within the connecting block, facilitates quick and easy installation and removal of the cutting strip. When the cutting strip needs replacement, simply press the lever to disengage the locking block from the slot, and the cutting strip can be easily removed for replacement, improving equipment maintenance efficiency and reducing replacement costs and time.

[0018] In a preferred embodiment of a high-voltage switch housing port cutting device, a flat collecting pipe is fixedly connected to the side of the fixed frame away from the support block. The collecting pipe is vertically arranged, and its plate surface is perpendicular to the central axis of the support ring. Both sides of the collecting pipe have openings that are connected. The left side of the collecting pipe passes through the interior of the fixed frame, and the left opening of the collecting pipe faces the cutting component. A collecting box is fixedly connected to the top of the base, and a connecting pipe is fixedly connected to the top of the collecting box. The end of the connecting pipe away from the collecting box is connected to the right opening of the collecting pipe. A pull-out groove is opened on one side of the collecting box, and a filter box is slidably connected in the pull-out groove. An air pump is fixedly connected inside the collecting box, and the air pump is located below the filter box. An air suction pipe is fixedly connected to the air pump's suction end, and an exhaust pipe is fixedly connected to the air pump's exhaust end. The suction pipe is located inside the collecting box, and the exhaust pipe extends out of the collecting box.

[0019] With the above structural design, during the cutting process, the air pump creates a negative pressure in the collection box through the extraction pipe. Cutting debris is drawn into the collection box through the collection pipe, filtered by the filter box, and then discharged through the exhaust pipe. This effectively prevents debris from scattering everywhere, maintains a clean working environment, and facilitates centralized processing of the collected debris, reducing cleaning workload and improving production safety and environmental friendliness.

[0020] As a preferred implementation of a high-voltage switch housing port cutting device, a snap-fit ​​block is fixedly connected to the outside of the filter box, and a snap-fit ​​assembly is provided on the side of the collection box with a pull-out groove. The snap-fit ​​assembly is located at the bottom of the snap-fit ​​block and includes a housing. The housing is fixedly connected to the side of the collection box, and a sliding rod is slidably connected inside the housing. The sliding rod is vertically arranged, and the top end of the sliding rod protrudes from the housing and can snap with the snap-fit ​​block. The bottom end of the sliding rod is connected to the top of the slider. The slider is vertically slidably connected inside the housing. A vertically arranged spring and a pull rod are fixedly connected to the bottom of the slider. The bottom end of the spring is connected to the inner bottom of the housing, and the pull rod is vertically slidably connected to the housing. The bottom end of the pull rod protrudes from the housing and is fixedly connected to a pull block.

[0021] With the above structural design, when the filter box needs to be cleaned, pull the pull block to lower the sliding rod and disengage it from the locking block, then the filter box can be pulled out for cleaning. Release the pull block, the spring returns to its original position, and the sliding rod rises, allowing it to re-lock into the locking block.

[0022] As a preferred implementation of a high-voltage switch housing port cutting device, a collection box is slidably connected to the top of the base. The collection box is located below the support ring, and the sliding direction of the collection box is set along the central axis of the support ring.

[0023] With the above structural design, the collection box is located below the support ring, which can collect larger debris that falls during the cutting process, reducing the impact of debris on the working environment and equipment, and keeping the work site clean and orderly.

[0024] As a preferred implementation of a high-voltage switch housing port cutting device, the fixed frame includes a top plate and two oppositely arranged side plates. The top plate is horizontally arranged, and the two side plates are located on the left and right sides of the bottom of the top plate, respectively, and the two side plates are perpendicular to the top plate. A support ring is located between the two side plates, and the central axis of the support ring is arranged along the front-back direction of the top plate. Support rods are connected between the two side plates and the outer circumferential surface of the support ring, and the support rods are horizontally arranged.

[0025] The above structural design uses a top plate and two side plates for the fixed frame, which are connected to the support rings by support rods to form a stable frame structure. This provides reliable support for the entire device, ensuring the stability of each component during the cutting process, reducing vibration caused by structural instability, and thus improving cutting accuracy and the service life of the equipment.

[0026] The beneficial effects of this invention include: 1. When the adjusting ring is rotated, slide rod one is restricted within the slide groove and cannot rotate with the adjusting ring. Instead, slide rod one slides relative to the slide groove. As slide rod one slides within the slide groove, slide rod two moves radially along the support ring. When all slide rod twos move synchronously toward the center of the support ring, smaller high-voltage switch housings can be clamped, and vice versa, larger high-voltage switch housings can be clamped. This allows for the clamping of high-voltage switch housings of different diameters.

[0027] 2. The dual-head motor can drive two small pulleys to rotate synchronously. When the small pulleys rotate, they can drive two large pulleys to rotate simultaneously through the synchronous belt. When the two large pulleys rotate synchronously, they will drive slide rod one to slide in the slide groove through two adjusting rings, which will then drive slide rod two to move. This allows for stable clamping of the high-voltage switch housing at two positions in the axial direction. The output shaft of the dual-head motor is locked in place, so the clamping will not loosen.

[0028] 3. When the cutting strip needs to be replaced, simply press the lever to disengage the locking block from the slot, and the cutting strip can be easily removed for replacement, which improves the maintenance efficiency of the equipment and reduces replacement costs and time consumption.

[0029] 4. This application utilizes a collection box to collect larger debris that falls during the cutting process. Simultaneously, an air pump creates a negative pressure in the collection box via a suction pipe, allowing smaller debris generated during cutting to be drawn into the collection box and collected into a filter box. This effectively prevents debris from scattering, maintains a clean working environment, facilitates centralized processing of the collected debris, reduces cleaning workload, and improves production safety and environmental friendliness.

Detailed Implementation

[0033] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Reference Figure 1-3 This specific embodiment proposes a high-voltage switch housing port cutting device, including a base 1, and a fixed frame 2 is fixedly connected to the top of the base 1. The fixed frame 2 includes a top plate 41 and two oppositely arranged side plates 42. The top plate 41 is horizontally arranged, and the two side plates 42 are located on the left and right sides of the bottom of the top plate 41, respectively, and the two side plates 42 are perpendicular to the top plate 41.

[0035] A support ring 5 is provided between the two side plates 42. The central axis of the support ring 5 is set horizontally and along the front-back direction of the top plate 41. A support rod 4 is connected between the two side plates 42 and the outer circumference of the support ring 5. The support rod 4 is set horizontally and can fix the support ring 5.

[0036] A collection box 3 is slidably connected to the top of the base 1. The collection box 3 is located below the support ring 5, and its sliding direction is set along the central axis of the support ring 5. The collection box 3 can collect large debris that falls during the cutting process, making it easy to handle.

[0037] Reference Figure 1-4An adjusting ring 14 is coaxially rotatably connected to the outer periphery of a support ring 5. The end face of the adjusting ring 14 has several identical grooves 15, which are evenly distributed in an array around the circumference of the adjusting ring 14. On the radial surface of the adjusting ring 14, each groove 15 extends obliquely. The extension direction of the groove 15 has both radial and circumferential components; that is, the extension direction of the groove 15 is neither along the radial nor circumferential direction of the adjusting ring 14. The projection of the groove 15 onto the radial surface of the adjusting ring 14 can be rectangular or arc-shaped, preferably arc-shaped. When the projection of the groove 15 onto the radial surface of the adjusting ring 14 is rectangular, the extension direction of the groove 15 intersects, but is not perpendicular to, the line connecting the midpoint of the extension direction of the groove 15 to the center of the adjusting ring 14 on the radial surface of the adjusting ring 14. When the projection of the slide groove 15 onto the radial surface of the adjusting ring 14 is arc-shaped, the extension direction of the slide groove 15 is not set along the circumference of the adjusting ring 14. A cylindrical slide rod 16 is slidably connected within each slide groove 15. The outer diameter of the slide rod 16 matches the width of the slide groove 15, and the axial direction of the slide rod 16 is parallel to the central axis of the adjusting ring 14. A cylindrical slide rod 38 is vertically connected to one end of the slide rod 16 that extends out of the slide groove 15. The slide rod 16 and slide rod 38 are connected to form a T-shaped rod. The slide rod 38 slides radially along the adjusting ring 14 through the outer circumference of the support ring 5. When the adjusting ring 14 rotates around its central axis, the groove 15 extends obliquely on the radial surface of the adjusting ring 14. The extension direction of the groove 15 has both radial and circumferential components. Therefore, under the constraint of the second sliding rod 38 and the groove 15, the sliding rod 16 can slide both radially and circumferentially along the adjusting ring 14. The sliding of the first sliding rod 16 in the groove 15 is a combined effect of radial and circumferential motion. One end of the second sliding rod 38 that slides into the support ring 5 is connected to a clamping block 17. The clamping block 17 has a shaft-like structure, and its axial direction is parallel to the central axis of the support ring 5.

[0038] Two support rings 5 ​​and two adjusting rings 14 are provided, and the two support rings 5 ​​and the two adjusting rings 14 are coaxially arranged. A drive assembly is fixedly installed on the outside of the left side plate 42 of the fixed frame 2. The drive assembly includes a support block 10, and a double-headed motor 11 is fixedly connected to the middle of the support block 10. The axial direction of the output shaft of the double-headed motor 11 is parallel to the central axis of the support ring 5. The output ends of the two output shafts of the double-headed motor 11 are fixedly connected to small pulleys 9. A large pulley 12 is coaxially fixedly connected to the outer periphery of each support ring 5. Each small pulley 9 is connected to a large pulley 12 through a synchronous belt 13. The left side plate 42 of the fixed frame 2 has a notch 43 for the synchronous belt 13 to pass through.

[0039] The dual-head motor 11 can drive two small pulleys 9 to rotate synchronously. When the small pulleys 9 rotate, they can drive two large pulleys 12 to rotate simultaneously via the synchronous belt 13. When the two large pulleys 12 rotate synchronously, the two adjusting rings 14 will rotate. Since the sliding rod 16 is restricted in the sliding groove 15, the sliding rod 16 cannot rotate with the adjusting ring 14, but slides relative to the sliding groove 15. As the sliding rod 16 slides in the sliding groove 15, the sliding rod 2 38 will move along the radial direction of the support ring 5. When all the sliding rods 2 38 move synchronously towards the center of the support ring 5, a smaller high-voltage switch housing can be clamped, and vice versa, a larger high-voltage switch housing can be clamped. This achieves the clamping of high-voltage switch housings of different diameters. The output shaft of the dual-head motor 11 is locked and will not loosen.

[0040] Reference Figure 1-4 In this embodiment, when the dual-head motor 11 drives the adjusting ring 14 to rotate clockwise, the slide bar 38 will move towards the center of the support ring 5, thus adapting to a smaller high-voltage switch housing; when the dual-head motor 11 drives the adjusting ring 14 to rotate counterclockwise, the slide bar 38 will move in the opposite direction, thus adapting to a larger high-voltage switch housing.

[0041] Reference Figure 1-5 A cutting assembly is installed inside the fixed frame 2, located between two support rings 5. The cutting assembly includes a first cylinder 6 and a cutting strip 19. There are two first cylinders 6, which are connected to the bottom of the top plate 41. The output shafts of the two first cylinders 6 extend and retract synchronously. The output shafts of the first cylinders 6 are vertically arranged, and the output end of each first cylinder 6 is connected to a second cylinder 18. The output shafts of the two second cylinders 18 are horizontal and collinear, and are perpendicular to the central axis of the support ring 5. The output shafts of the two second cylinders 18 extend and retract synchronously in opposite directions. The two ends of the cutting strip 19 are connected to the output ends of the output shafts of the two second cylinders 18 respectively. Driven by the first cylinder 6, the cutting strip 19 can rise and fall vertically. Driven by the second cylinder 18, the cutting strip 19 can move back and forth stably in the horizontal direction in a direction perpendicular to the axis of the adjusting ring 14. The cutting strip 19 can cut the high-voltage switch housing by pressing down and moving back and forth horizontally. The cutting assembly also includes cylinder 39, of which there are two. The output shaft of cylinder 39 is vertically set and connected to the top of base 1. The output end of the output shaft of each cylinder 39 is connected to a cylinder 18. The output shaft of cylinder 39 and the output shaft of cylinder 16 extend and retract synchronously in opposite directions. Cylinder 39 and cylinder 16 cooperate with each other to make the lifting and lowering of the cutting strip 19 more stable.

[0042] Reference Figure 5-7Both ends of the cutting strip 19 have slots 22. The output end of the output shaft of the second cylinder 18 is fixedly connected to a connecting block 20. A limit plate 25 is fixedly connected inside the connecting block 20. The plate surface of the limit plate 25 is horizontally set with the output shaft of the second cylinder 18. Both sides of the limit plate 25 are vertically connected to compression springs 24. The end of the compression spring 24 away from the limit plate 25 is connected to a lever 23. The lever 23 can slide in the connecting block 20 along the axial direction of the compression spring 24. The connecting block 20 has a lever groove 40, which is opened along the axial direction of the compression spring 24. One side of the lever 23 extends out from the lever groove 40. The side of the lever 23 away from the compression spring 24 is connected to a locking block 21. The locking block 21 passes through the connecting block 20 and engages with the locking groove 22.

[0043] When replacing the cutting strip 19, pinch the side of the lever 23 that is exposed in the lever groove 40 and squeeze the two compression springs 24. Both locking blocks 21 will move into the interior of the connecting block 20, thereby disengaging from the locking groove 22. After the locking blocks 21 disengage from the locking groove 22, the cutting strip 19 can be separated from the cylinder 6, which facilitates the replacement of the cutting strip 19 and improves the replacement efficiency.

[0044] Reference Figure 1-3 , Figure 8 and Figure 9 Two parallel, flat collecting tubes 8 are fixedly connected to the side plate 42 on the right side of the fixed frame 2. The collecting tubes 8 are vertically arranged, and their surfaces are perpendicular to the central axis of the support ring 5. The two collecting tubes 8 are located on the front and rear sides of the cutting assembly, respectively. Each collecting tube 8 has an opening on both its left and right sides, which are connected. The opening on the left side of the collecting tube 8 is elongated, and the opening on the right side is a round hole. The left side of the collecting tube 8 passes through the side plate 42 on the right side of the fixed frame 2, and the left opening of each collecting tube 8 faces the cutting assembly. A collecting box 7 is fixedly connected to the top of the base 1. Two connecting tubes 26 are fixedly connected to the top of the collecting box 7. The end of the connecting tube 26 away from the collecting box 7 is connected to the right opening of the collecting tube 8. A pull-out groove is provided on one side of the collection box 7, and a filter box 27 is slidably connected in the pull-out groove. An air pump 32 is fixedly connected inside the collection box 7. The air pump 32 is located below the filter box 27. An air suction pipe 33 is fixedly connected to the air suction end of the air pump 32, and an exhaust pipe 31 is fixedly connected to the air exhaust end of the air pump 32. The air suction pipe 33 is located inside the collection box 7, and the exhaust pipe 31 extends out of the collection box 7.

[0045] When the air pump 32 is working, it will draw out the air in the collection box 7, making the collection box 7 a negative pressure state. The collection pipe 8 will then draw in the small debris generated during cutting. The small debris can enter the collection box 7 through the connecting pipe 26 with the airflow. The small debris falls into the filter box 27. The bottom of the filter box 27 has a small hole. The airflow passes through the filter box 27 and can be discharged through the exhaust pipe 31 of the air pump 32.

[0046] Reference Figure 9 and Figure 10 A snap-fit ​​block 30 is fixedly connected to the outside of the filter box 27. The collection box 7 has a snap-fit ​​assembly on the side with a pull-out groove. The snap-fit ​​assembly is located at the bottom of the snap-fit ​​block 30. The snap-fit ​​assembly includes a housing 28, which is fixedly connected to the side of the collection box 7. A sliding rod 29 is slidably connected inside the housing 28. The sliding rod 29 is vertically set. The top end of the sliding rod 29 protrudes from the housing 28 and can snap with the snap-fit ​​block 30. The bottom end of the sliding rod 29 is connected to the top of the slider 34. The slider 34 is vertically slidably connected inside the housing 28. A vertically set spring 36 and a pull rod 35 are fixedly connected to the bottom of the slider 34. The bottom end of the spring 36 is connected to the inner bottom of the housing 28. The pull rod 35 is vertically slidably connected to the housing 28. The bottom end of the pull rod 35 protrudes from the housing 28 and is fixedly connected with a pull block 37.

[0047] When the filter box 27 needs to be removed, manually pull down the pull block 37. The pull block 37 moves the pull rod 35 downward, compressing the spring 36 and causing the slider 34 to move downward, which in turn moves the sliding rod 29 downward. The sliding rod 29 disengages from the locking block 30, and the filter box 27 can be removed. When the filter box 27 is pushed back in, release the pull block 37, the spring 36 returns to its original position, and the sliding rod 29 can move upward and re-engage with the locking block 30.

[0048] Work process: When the dual-head motor 11 in the drive assembly starts, it drives the large pulleys 12 on the outer periphery of the two support rings 5 ​​to rotate synchronously through the small pulley 9 and the synchronous belt 13, thereby driving the coaxial adjusting ring 14 to rotate.

[0049] When the adjusting ring 14 rotates, the evenly distributed sliding grooves 15 on its end face slide relative to the slide rod 16, pushing the slide rod 38 to move radially along the support ring 5. The shaft-shaped clamping block 17 at the end of the slide rod 38 can contact the outer peripheral surface of the high-voltage switch housing. Multiple clamping blocks 17 are evenly distributed to form a ring-shaped clamping, ensuring that the clamping force is evenly distributed and avoiding local stress concentration.

[0050] During cutting, cylinders 1-6 and 3-9 operate synchronously: when the output shaft of cylinder 1-6 presses down, the output shaft of cylinder 3-9 pushes up, causing the cutting strip 19 to descend vertically to the predetermined cutting height; conversely, when cylinder 1-6 lifts up and cylinder 3-9 pulls down, the cutting strip 19 rises to its original position. The output shafts of cylinders 2-18 reciprocate horizontally in sync, driving the cutting strip 19 to perform a horizontal sawing action, thus cutting the end of the housing.

[0051] When the cutting strip 19 needs to be replaced, press the lever 23 on the connecting block 20. The compression spring 24 will compress and cause the locking block 21 to disengage from the slots 22 at both ends of the cutting strip 19, so that the old cutting strip 19 can be removed. When installing the new strip, the operation is reversed. The locking block 21 will automatically lock into the slot 22 under the action of the compression spring 24 to complete the fixation.

[0052] After the air pump 32 is started, it draws air out of the collection box 7 through the suction pipe 33 to create negative pressure. The fine debris generated during cutting is sucked into the collection pipe 8, enters the collection box 7 through the connecting pipe 26, and the debris is deposited in the filter box 27. The airflow is discharged through the small hole at the bottom of the filter box 27 and released to the outside through the exhaust pipe 31. When the filter box 27 needs to be cleaned, pull the pull block 37 on the side of the collection box 7. The sliding rod 29 descends and disengages from the locking block 30, allowing the filter box 27 to be pulled out and the debris to be emptied. After resetting, the spring 36 pushes the sliding rod 29 to re-lock.

[0053] Larger debris falls directly into the collection box 3 below the support ring 5. The collection box 3 can be slid out along the central axis of the support ring 5 for easy cleaning.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
