Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a cutting device and method for gas-tight fasteners. Background Technology

[0002] A gas seal is a sealing component used to seal gaseous media. It has good sealing performance and durability. Gas seals are commonly used to seal the connection parts in pipes, containers or other equipment to ensure that gas or liquid leakage is prevented. Gas seals are generally manufactured by machining on a cutting machine tool.

[0003] When machining hermetic fasteners using a machine tool, a large amount of debris is generated. Currently, the mainstream method for handling these debris is to allow the debris to fall directly into the machine tool. After machining, workers use air nozzles to blow away the debris. This method has significant drawbacks: Firstly, the cleaning process needs to be performed separately after machining, increasing the workload of workers. The cleaning action requires interrupting the machining process, increasing non-productive time and reducing overall machining efficiency. Secondly, during the cutting process, debris is easily scattered, and some debris can embed in the gaps of components such as slide rails and tool holders. This not only increases the difficulty of cleaning but may also cause wear on components due to debris accumulation, affecting the machining accuracy and service life of the machine tool. Therefore, this paper proposes a hermetic fastener cutting device and its machining method to address these issues. Summary of the Invention

[0033] Example 1

[0034] like Figures 1-10 As shown, a gas-tight fastener cutting processing device and its processing method include a machine tool body 5 and a first housing plate 6. A tailstock 15 is fixedly connected to the inner side of the machine tool body 5 via a linear module. The linear module includes X-axis, Y-axis, and Z-axis modules (existing technology, not described in detail here). A first tool post 8 is fixedly connected to one end of the tailstock 15, and a second tool post 11 is fixedly connected to one end of the first tool post 8. The first tool post 8 is used to clamp drill bits, boring tools, etc., and the second tool post 11 is used to clamp cutting tools. A first housing plate 6 and a second housing plate 7 are fixedly connected to the inner side of the machine tool body 5. The second housing plate 7 and the first tool post 6... One end of each frame 8 is equipped with a cleaning mechanism 1, and the discharge end of the cleaning mechanism 1 is equipped with an anti-blocking mechanism 2. One end of the first box plate 6 is fixedly connected to a follower mechanism 4, and the inner side of the follower mechanism 4 is fixedly connected to a spray pipe 13. One end of the spray pipe 13 is connected to a delivery pipe 12, which is made of an oil delivery hose to ensure that the spray pipe 13 can move normally. One end of the second box plate 7 is rotatably connected to a chuck 14, which can clamp and fix the workpiece required for processing the gas seal buckle. The inner side of the machine tool body 5 is fixedly connected to a positioning mechanism 3, and the positioning mechanism 3 is located on one side of the cleaning mechanism 1.

[0035] As a further improvement to the present invention, such as Figure 1 and Figure 3 As shown, a collection box 9 is placed inside the machine tool body 5, and the collection box 9 is located below the discharge end of the cleaning mechanism 1. A filter screen 10 is fixedly connected to the inside of the collection box 9. The collection box 9 enables the centralized collection of cutting chips, and the filter screen 10 is installed inside the box for solid-liquid separation. The filter screen 10 maintains an appropriate distance from the bottom of the collection box 9 so that the separated coolant can be smoothly discharged from the bottom of the box, while the cutting chips are retained above the filter screen 10, thus achieving effective chip recycling and coolant recycling.

[0036] As a further improvement to the present invention, such as Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 As shown, the cleaning mechanism 1 includes a transition frame 101 fixedly connected to the second box plate 7. The transition frame 101 is coaxially arranged on the outside of the chuck 14. The other end of the transition frame 101 is fixedly connected to a jet frame 102. The inner wall of the jet frame 102 is provided with jet holes 103. The top of the jet frame 102 is connected to an air pipe 117, and the other end of the air pipe 117 is connected to an external high-pressure air source. The upper inner wall, left inner wall and right inner wall of the jet frame 102 are all provided with jet holes 103. The blowing direction of each jet hole is towards the inlet end of the chip removal pipe 116. During the workpiece cutting process, the air ejected from the jet holes 103 High-pressure gas can concentrate and blow cutting chips to the inlet of chip discharge pipe 116, achieving efficient directional collection of chips; the other end of the jet frame 102 is fixedly connected to a first elastic frame 104, and the other end of the first elastic frame 104 is fixedly connected to a first fixed frame 105; the cleaning mechanism 1 also includes a guide frame 110 fixedly connected to the first tool holder 8, the other end of the guide frame 110 is fixedly connected to a second elastic frame 111, the other end of the second elastic frame 111 is fixedly connected to a second fixed frame 112, the bottom end of the guide frame 110 is fixedly connected to the chip discharge pipe 116, and the outlet end of the chip discharge pipe 116 is located at the collection point. Above the header 9; both the first elastic frame 104 and the second elastic frame 111 are made of elastic rubber cloth (such as neoprene rubber cloth, polyurethane rubber cloth, or silicone rubber composite cloth). Their excellent flexibility ensures that the first fixed frame 105 and the second fixed frame 112 move flexibly without interfering with other components. Simultaneously, the elastic rubber cloth possesses high strength and wear resistance, able to withstand long-term friction from cutting chips and erosion from cutting fluid, effectively extending the overall service life of the chip removal system and ensuring long-term stability of sealing and movement performance. The first fixed frame 105 and the second fixed frame 112 are designed with the same specifications and dimensions to ensure… The two can be precisely aligned and fully fitted together; at the same time, sealing strips are embedded in the contact surfaces of the first fixed frame 105 and the second fixed frame 112. The elastic compression of the sealing strips fills the gaps and effectively blocks the leakage path of chips and cutting fluid, ensuring the smoothness of the docking process and strengthening the sealing performance of the connection parts, maintaining the stability of the closed processing environment; the bottom of the second elastic frame 111 and the guide frame 110 is designed to be inclined towards the chip discharge pipe 116, ensuring that the cutting chips can automatically slide towards the inlet of the chip discharge pipe 116 under the action of high-pressure air jet and gravity, realizing efficient directional collection of chips.

[0037] As a further improvement to the present invention, such as Figure 2 , Figure 3 and Figure 4As shown, both ends of the first fixed frame 105 are fixedly connected to the first ear plate 106. One end of the first ear plate 106 is movably connected to the first cylinder 107 via a spherical hinge. The first cylinder 107 drives the first fixed frame 105 to adjust its position through the first ear plate 106. When it is necessary to clamp the workpiece to the chuck 14, the first cylinder 107 moves the first fixed frame 105 and the first elastic frame 104 toward the transition frame 101, exposing the chuck 14, which is convenient for the operator to perform workpiece clamping operations. The outer side of the first cylinder 107 is fixedly connected to the first ball 108. The outer side of the first ball 108 is rotatably connected to the first limiting shell 109, and the first limiting shell 109 is fixedly connected to the second box plate 7. The first ball 108 can rotate freely within the first limiting shell 109. After the first fixed frame 105 and the second fixed frame 112 are docked, the first tool holder 8 drives the second fixed frame 112 to move through the guide frame 110, the second ear plate 113, the second cylinder 114 and the third ear plate 115. At the same time, the second fixed frame 112 can drive the first fixed frame 105 to make corresponding displacements. During this process, the first cylinder 107 and the second cylinder 114 will automatically extend and retract to ensure that the two fixed frames always remain in close contact. In order to accurately control the contact pressure, a pressure sensor can be installed on the contact surface between the first fixed frame 105 and the second fixed frame 112. By monitoring the pressure value in real time and setting a reasonable threshold range, the first cylinder 107 and the second cylinder 114 can be precisely controlled.

[0038] Both ends of the second fixed frame 112 are fixedly connected to third ear plates 115, and both ends of the guide frame 110 are fixedly connected to second ear plates 113. One end of the third ear plate 115 is fixedly connected to a second cylinder 114, and the other end of the second cylinder 114 is fixedly connected to the second ear plate 113. The second cylinder 114 can adjust the position of the second fixed frame 112 through the third ear plate 115. When it is necessary to clamp the tool to the inside of the first tool holder 8 or the second tool holder 11, the second cylinder 114 moves the second fixed frame 112 and the second elastic frame 111 towards the guide frame 110, so that the first tool holder 8 or the second tool holder 11 is exposed, which is convenient for the operator to perform tool clamping operations. The linear module first drives the first tool holder 8 and the second tool holder 11 to move the tool to the side of the workpiece through the tailstock 15. After the tool is aligned, the first fixed frame 105 is then docked with the second fixed frame 112. First, the positioning mechanism 3 is used to... The first cylinder 107 is kept horizontal, at which point the first fixed frame 105 and the second fixed frame 112 are aligned. Subsequently, the first cylinder 107 drives the first fixed frame 105 through the first ear plate 106, while the second cylinder 114 drives the second fixed frame 112 through the third ear plate 115, causing the two to move towards each other and complete docking. At this time, the transition frame 101, the air jet frame 102, the first elastic frame 104, the first fixed frame 105, the second fixed frame 112, the second elastic frame 111, and the guide frame 110 together form a closed cutting space, so that the cutting process is completed in the closed space, effectively preventing chip splashing and avoiding them from getting embedded in the gaps of components such as the slide rail, the first tool holder 8, and the second tool holder 11. At the same time, the chips generated by cutting fall directly into the collection box 9 through the chip discharge pipe 116, eliminating the need for manual blowing and cleaning, significantly reducing the labor intensity and cleaning difficulty of the workers, and improving the overall processing efficiency.

[0039] As a further improvement to the present invention, such as Figure 3 , Figure 4 and Figure 5As shown, the anti-blocking mechanism 2 includes a third cylinder 201 fixedly connected to the tailstock 15. A connecting plate 202 is fixedly connected to the other end of the third cylinder 201. Connecting rods 203 are rotatably connected to both sides of the center line of one end of the connecting plate 202. A rotating plate 204 is rotatably connected to the other end of the connecting rods 203. Simultaneously, the rotating plate 204 is rotatably connected to the guide frame 110. A fixing rod 205 is fixedly connected to the other end of the rotating plate 204. A row of cutters 206 is fixedly connected to one end of the fixing rod 205. A tempered glass observation window is provided on the side wall of the guide frame 110 for real-time monitoring of the internal chip discharge status. When a blockage is detected, the third cylinder 201 drives the connecting plate 202 to move closer to the guide frame 110. Then, the guide frame 110 drives the connecting rods 203 to move closer to the guide frame 110. Simultaneously, one end of the connecting rod 203 will rotate around the axis between itself and the connecting plate 202, moving away from the horizontal center line of the third cylinder 201. Then, the connecting rod 203 pushes the rotating plate 204 to rotate around the axis between itself and the guide frame 110. The upper rotating plate 204 will rotate counterclockwise with the cutter 206 via the corresponding fixed rod 205 (viewed from left to right), and the lower rotating plate 204 will rotate clockwise with the cutter 206 via the corresponding fixed rod 205 (viewed from left to right). This causes the upper and lower rows of cutters 206 to gradually approach and cut the long strip-shaped cutting chips blocking the inlet of the chip removal pipe 116, thereby effectively preventing the chip removal pipe from clogging. This design not only avoids machine downtime for manual cleaning due to blockage and ensures the continuity of the cutting and chip removal process, but also significantly improves the overall processing efficiency.

[0040] As a further improvement to the present invention, such as Figure 3 , Figure 4 and Figure 5 As shown, the cutter 206 has two rows, upper and lower, which are staggered and their cutting edges can be staggered to ensure that when cutting long strips of chips, the cutting edges of the upper and lower rows of cutters 206 will not touch each other and cause damage, while ensuring the cutting effect of the upper and lower rows of cutters 206. The number of fixing rods 205 corresponds to the number of rows of cutters 206. The cutters 206 and fixing rods 205 in the upper row are movable between the guide frame 110, and the cutters 206 and fixing rods 205 in the lower row are movable between the chip discharge pipe 116, ensuring that the cutters 206 can work normally. The cutters 206 on both the upper and lower sides can improve the cutting efficiency and effect.

[0041] As a further improvement to the present invention, such as Figure 2 and Figure 6As shown, the positioning mechanism 3 includes a fourth cylinder 301 fixedly connected to the machine tool body 5. A crossbar 302 is fixedly connected to the other end of the fourth cylinder 301. Side rods 303 are fixedly connected to both ends of the crossbar 302, and a positioning ring 304 is fixedly connected to the bottom end of each side rod 303. The fourth cylinder 301 can move horizontally along the crossbar 302 and side rods 303, causing the positioning ring 304 to engage with the outside of the positioning cone 305 for positioning. The positioning mechanism 3 also includes a positioning cone 305 fixedly connected to the first cylinder 107. A transition rod 306 is fixedly connected to the other end of the positioning cone 305, and the transition rod 306 passes through the positioning ring 304. The two positioning rings 304 are symmetrically distributed on both sides of the vertical center line of the crossbar 302. When the first cylinder 107... When the first ball 108 rotates within the first limiting shell 109, it synchronously drives the positioning cone 305 and the transition rod 306 to swing, with the transition rod 306 acting as a limiting guide. When the first cylinder 107 needs to be horizontally positioned, the positioning ring 304 can slide along the transition rod 306 and be sleeved on the outside of the positioning cone 305 to achieve horizontal fixation of the first cylinder 107. After the first fixed frame 105 and the second fixed frame 112 are docked, the positioning ring 304 can move from the outside of the positioning cone 305 back to the outside of the transition rod 306, releasing the positioning constraint, so that the second fixed frame 112 can drive the first fixed frame 105 to move synchronously, thereby ensuring that the first tool holder 8 and the second tool holder 11 can adjust the tool position normally and maintain the continuity and stability of the machining process.

[0042] As a further improvement to the present invention, such as Figure 1 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the follower mechanism 4 includes a top plate 401 fixedly connected to the first box plate 6. A guide rail 402 is fixedly connected to the bottom end of the top plate 401. A slider 403 is slidably connected to the outer side of the guide rail 402. A vertical rod 406 is fixedly connected to the bottom end of the slider 403. A second limiting shell 407 is fixedly connected to one end of the vertical rod 406. A second ball 408 is rotatably connected to the inner side of the second limiting shell 407. The spray pipe 13 is fixedly connected to the second ball 408. The second limiting shell 407 is fixedly connected to the second elastic frame 111. When the positions of the first knife holder 8 and the guide frame 110 are finely adjusted, the second elastic frame 111 deforms accordingly. The second limiting shell 407 is then connected to the vertical rod 406. The fixed connection maintains a stable relative position, thereby ensuring the normal operation of the spray pipe 13. A locking screw 409 is spirally connected to the inner side of one end of the second limiting shell 407, and the locking screw 409 abuts against the second ball 408. When the linear module moves with the first tool holder 8 through the tailstock 15, the first tool holder 8 will also move together through the guide frame 110 and the second elastic frame 111. The second elastic frame 111 will slide along the guide rail 402 with the slider 403 through the second limiting shell 407 and the vertical rod 406. The spray direction of the spray pipe 13 can be adjusted by the mutual rotation between the second ball 408 and the second limiting shell 407. After adjustment, tighten the locking screw 409 to make it abut against the second ball 408 to lock the spray direction and ensure that the coolant is accurately sprayed to the processing area of ​​the workpiece and the tool.

[0043] As a further improvement to the present invention, such as Figure 8 As shown, a telescopic electromagnet 404 is fixedly connected to the inner side of the slider 403, and a limit block 405 is fixedly connected to the other end of the telescopic electromagnet 404, with the limit block 405 abutting against the guide rail 402. When the slider 403 slides along the guide rail 402, the telescopic electromagnet 404 is de-energized, and the limit block 405 is not abutting against the guide rail 402, thus ensuring that the slider 403 can slide freely along the guide rail 402. When the slider 403 moves to the designated position, the telescopic electromagnet 404 is energized, causing the limit block 405 to abut against the guide rail 402, preventing the slider 403 from sliding freely, thus ensuring the stability of the spray pipe 13 during operation.

[0044] As a further improvement to the present invention, such as Figures 1-10 As shown, S1: The workpiece is held by the chuck 14, and the corresponding tool is held by the first tool post 8 and the second tool post 11; S2: The cleaning mechanism 1 is positioned by the positioning mechanism 3; S3: The cleaning mechanism 1 then covers the chuck 14, the first tool post 8 and the second tool post 11, and the follower mechanism 4 moves along with the operation of the cleaning mechanism 1; S4: The workpiece is cut by the first tool post 8 or the second tool post 11; S5: Coolant is sprayed onto the workpiece and the tool by the spray pipe 13 during the cutting process.
