Description

Technical Field

[0001] This invention relates to the field of sleeve manufacturing technology, and in particular to a manufacturing equipment and method for a test sleeve for extruded deformed nuts. Background Technology

[0002] In mechanical assembly, especially in the fields of aviation, aerospace and high-end equipment manufacturing, a type of fastener called "extrusion deformation nut" (or "self-locking nut") is often used. To ensure its assembly quality and reliability, a special test installation sleeve is required for its installation and testing. This test sleeve must have extremely high dimensional accuracy, surface finish and structural consistency to ensure the accuracy and comparability of the test results. Therefore, when manufacturing the test sleeve, it is necessary to use a turning machine to machine its outer dimensions.

[0003] In existing turning processes, after the workpiece is separated from the clamping end by the milling cutter, it is often in a free fall state. At this time, the following problems exist: during the fall, the workpiece is very likely to collide with the machine tool or other hard objects, causing damage or deformation to the machined surface, affecting the final accuracy; at the same time, the residual high temperature accumulated by the turning process also brings additional risks: it may not only burn the worktable or adjacent parts, but also pose a safety hazard of burns if personnel accidentally come into contact with it. Therefore, this application proposes a manufacturing equipment and manufacturing method for a test sleeve for extrusion deformation of nuts. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art where workpieces are easily damaged by falling after processing and where there are high internal temperatures, by proposing a manufacturing device and method for a test sleeve for extruded deformation nuts.

[0005] In a first aspect, the present invention provides a manufacturing apparatus for a test sleeve for a nut subjected to extrusion deformation, comprising a machine tool and a clamping end for holding the workpiece, wherein the machine tool is internally provided with a motor for driving the clamping end to rotate, and an external part of the machine tool is provided with a milling cutter and a moving module for driving the milling cutter to move, and further comprising: At least two sets of symmetrically distributed protective plates, each set of protective plates has a protective plate at its top, and the protective plates are rotatably connected to the interior of the protective plates, which are fixedly connected to the protective plates. A splash-proof mechanism is respectively installed on the outside of the two sets of protective plates. The splash-proof mechanism includes a lifting assembly and a swing assembly, wherein: The lifting assembly is used to drive the first protective plate to rise and block the flying iron filings, and the swing assembly is used to realize the swing of the second protective plate when the first protective plate moves. A cooling mechanism is located below the clamping end. The cooling mechanism includes a coolant reservoir, a baffle to close the flow channel of the reservoir, and a control assembly, wherein: The control component is used to control the operation of the baffle when the protective plate rises; The baffle is slidably connected to the inside of the liquid storage tank. A side plate is fixedly connected to the end of the baffle away from the liquid storage tank. Four sets of guide rods that slide through the side plate are fixedly connected to the outside of the liquid storage tank.

[0006] Optionally, the lifting assembly includes a hydraulic cylinder, a connecting frame, and a slide. The hydraulic cylinder is installed on the outside of the machine tool. The connecting frame is connected to the output end of the hydraulic cylinder. Both ends of the connecting frame are fixedly connected to the two sets of protective plates. The slide is opened on the side of the machine tool near the hydraulic cylinder. The connecting frame is slidably connected to the inside of the slide, and the slide has a T-shaped cross-section.

[0007] Optionally, the swing assembly includes a connecting roller, a traction rope, and two sets of guide wheels. The connecting roller is fixed to the outside of the connecting shaft, the traction rope is wound around the outside of the connecting roller, and the end of the traction rope away from the connecting roller is fixed to the outside of the machine tool. Both sets of guide wheels are fixed to the outside of the machine tool, and the traction rope is in contact with the two sets of guide wheels.

[0008] Optionally, the control component includes a second traction rope, a fixed plate, and a second guide wheel. The second traction rope is fixed to the bottom end of the first protective plate, the fixed plate is fixed to the bottom end of the side plate, the end of the second traction rope away from the first protective plate is fixed to the fixed plate, and the second guide wheel is fixed to the outside of the liquid storage tank. The second traction rope is in contact with the second guide wheel.

[0009] Optionally, a straight groove plate is fixed to the outer side of the side plate, a square plate is fixed to the outer side of the liquid storage tank, and a compression spring is fixed between the straight groove plate and the square plate.

[0010] Optionally, an overflow hole is provided on the outside of the liquid storage tank, and a guide pipe is installed inside the overflow hole.

[0011] Optionally, three sets of arc-shaped springs are fixedly connected to the outer sides of the second protective plate and the first protective plate.

[0012] Optionally, a limiting plate is fixed to the side of the second protective plate away from the arc spring, and the limiting plate is in contact with the outer side of the first protective plate.

[0013] Optionally, the machine tool is equipped with a blower, and the output end of the blower is connected to an air supply pipe. The end of the air supply pipe away from the blower passes through the liquid storage tank and extends into the interior of the liquid storage tank. A one-way valve is installed inside the air supply pipe.

[0014] Secondly, the present invention provides a method for manufacturing a test sleeve for extruded deformed nuts, applied to the manufacturing equipment for the test sleeve for extruded deformed nuts described in the first aspect, the method comprising the following steps: S1. Protection and preparation: After the workpiece is clamped at the clamping end, the hydraulic cylinder is started to drive the first protective plate to rise, and the second protective plate swings and closes to form an enclosure through the first traction rope and the connecting roller. At the same time, the first protective plate is linked to the side plate through the second traction rope to pull the baffle into the liquid storage tank to seal the bottom. S2. Machining and liquid collection: Start the motor and moving module, the milling cutter turns the rotating workpiece, and the sprayed coolant falls into the storage tank for storage. S3. Dropping and Cooling: After the workpiece is cut, it falls into the coolant in the storage tank for buffering and cooling. The blower is started to blow air into the storage tank through the air supply pipe to enhance cooling. S4. Reset and drain: The hydraulic cylinder retracts, and the first and second protective plates reset under the action of the arc spring. At the same time, the compression spring pushes the baffle to reset and open the bottom of the liquid storage tank, draining the coolant and allowing the workpiece to be removed.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention uses a lifting assembly to drive the two protective plates to rise to both sides of the workpiece, while simultaneously using a swing assembly to bring the second protective plate inward, thus quickly forming a high-temperature resistant protective enclosure around the workpiece. This design effectively blocks iron filings that fly during turning, ensuring personnel safety and improving the overall protective capability of the equipment.

[0016] Furthermore, through the structural design of the baffle and control components, the control components are linked with the baffle to close the liquid storage tank and form a coolant pool during processing, realizing the recovery and temporary storage of coolant. After processing, the workpiece falls into the liquid pool, and the impact is reduced and collision damage is avoided by the buffering effect of the liquid. At the same time, the coolant can quickly wrap around and cool the surface of the workpiece, which has the dual functions of buffer protection and uniform cooling. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 and Figure 2As shown, the present invention proposes a manufacturing equipment for a test sleeve for extrusion deformation nuts, including a machine tool 1 and a clamping end 2 for clamping the workpiece. During sleeve manufacturing, the bar is first clamped by the clamping end 2. The machine tool 1 is equipped with a motor that drives the clamping end 2 to rotate. The motor then drives the clamping end 2 to rotate at high speed, which in turn drives the workpiece (referring to the bar) to rotate at high speed. A milling cutter 3 and a moving module 4 that drives the milling cutter 3 are arranged on the outside of the machine tool 1. When the moving module 4 drives the milling cutter 3 to contact the workpiece, high-speed friction occurs between them. By moving the contact position between the milling cutter 3 and the bar through the moving module 4, the outer diameter of the bar can be machined to a specified size, which depends on the actual situation. During machining, coolant is continuously sprayed onto the contact surface between the workpiece and the milling cutter 3 to reduce the temperature and ensure smooth machining. It should be noted that the clamping end 2, milling cutter 3, and moving module 4 in this embodiment are all conventional and mature technologies in machining, and will not be elaborated upon further.

[0023] As one implementation method, such as Figure 3 - Figure 6 As shown, the manufacturing equipment in this embodiment also includes at least two sets of symmetrically distributed protective plates 5 and splash-proof mechanisms. Each set of protective plates 5 has a second protective plate 6 at its top. Both protective plates 5 and second protective plates 6 are made of high-temperature resistant material. A connecting shaft 7 is rotatably connected inside each protective plate 5, and the connecting shaft 7 is fixedly connected to the second protective plate 6. The second protective plate 6 can rotate along the top of the protective plate 5 via the connecting shaft 7. The splash-proof mechanisms are respectively disposed on the outer sides of the two sets of protective plates 5. Each splash-proof mechanism includes a lifting assembly and a swing assembly, wherein the lifting assembly is used for driving... Protective plate 5 rises to prevent metal chips from flying. During the processing of the bar stock, after the workpiece is clamped by clamping end 2, the lifting assembly first drives protective plate 5 to rise. Protective plate 5 then drives protective plate 6 to rise synchronously via connecting shaft 7. At this time, protective plate 5 and protective plate 6 are respectively positioned on both sides of the workpiece. The swing assembly is used to realize the linkage between protective plate 5 and protective plate 6 as protective plate 5 moves. Furthermore, when protective plate 5 rises, it also drives the swing assembly, which in turn drives the two sets of protective plates 6 to swing towards each other (the swing state of protective plate 6 is as follows). Figure 5 As shown), at this time, the protective plate 5, together with the swinging protective plate 6, can simply surround the side of the workpiece. The surrounding condition of the protective plate 5 and the protective plate 6 can effectively prevent the workpiece from being accidentally injured by flying iron chips during machining.

[0024] Furthermore, such as Figure 6 , Figure 7 and Figure 8As shown, the manufacturing equipment in this embodiment also includes a cooling mechanism, which is located below the clamping end 2. The cooling mechanism includes a liquid storage tank 8 for collecting coolant, a baffle 9 for sealing the downward flow channel of the liquid storage tank 8, and a control component. When coolant is sprayed during workpiece processing, the coolant will fall into the interior of the liquid storage tank 8 under the action of gravity. The control component is used to control the operation of the baffle 9 when the protective plate 5 rises. The baffle 9 is slidably connected to the interior of the liquid storage tank 8. A side plate 10 is fixedly connected to the end of the baffle 9 away from the liquid storage tank 8. When the protective plate 5 rises, the control component will drive the side plate 10 to move. Four sets of guide rods 11 are fixedly connected to the outside of the liquid storage tank 8, sliding through the side plate 10. The side plate 10 moves along the four... The outer side of the guide rod 11 drives the baffle 9 to move synchronously. Finally, when the protective plate 5 is raised, the control component drives the baffle 9 to be completely inside the liquid storage tank 8. The baffle 9 seals the internal channel of the liquid storage tank 8. At this time, the coolant cannot flow from the bottom of the liquid storage tank 8, so it accumulates inside the liquid storage tank 8 and is located above the baffle 9. When the workpiece is separated from the clamping end 2 by the milling cutter 3, the workpiece falls naturally and finally falls into the liquid storage tank 8. Due to the fluidity and compressibility of water (referring to coolant in this embodiment), the coolant can disperse the impact force when the workpiece falls, thereby avoiding damage caused by hard impact and playing a buffering role. Secondly, the coolant can coat the surface of the workpiece, thereby quickly cooling the workpiece physically.

[0025] As one implementation method, such as Figure 3 and Figure 6 As shown, the lifting assembly includes a hydraulic cylinder 12, a connecting frame 13, and a slide 14. The lifting assembly is described in detail below: The hydraulic cylinder 12 is installed on the outside of the machine tool 1. The connecting frame 13 is connected to the output end of the hydraulic cylinder 12. When the hydraulic cylinder 12 is running, its output end will drive the connecting frame 13 to move upward. The two ends of the connecting frame 13 are respectively fixed to the two sets of protective plates 5. The upward movement of the connecting frame 13 will drive the two sets of protective plates 5 to move upward synchronously, so that the protective plates 5 and the second protective plate 6 can protect the workpiece during processing. The slide groove 14 is opened on the side of the machine tool 1 near the hydraulic cylinder 12. The connecting frame 13 is slidably connected to the inside of the slide groove 14. The slide groove 14 has a T-shaped cross-section. When the connecting frame 13 moves, it will move stably along the inside of the slide groove 14. The T-shaped design of the slide groove 14 can guide the movement direction of the connecting frame 13, so that it moves in the preset direction and avoids the shaking of the connecting frame 13 when it moves.

[0026] Furthermore, such as Figure 3 , Figure 4 and Figure 5As shown, the swing assembly includes a connecting roller 15, a traction rope 16, and two sets of guide wheels 17. The swing assembly is described in detail below: The connecting roller 15 is fixed to the outside of the connecting shaft 7. In the initial state, the traction rope 16 is wound around the outside of the connecting roller 15. The end of the traction rope 16 away from the connecting roller 15 is fixed to the outside of the processing machine tool 1. When the protective plate 5 rises, the protective plate 5 will simultaneously drive the connecting shaft 7 and the second protective plate 6 to rise. The rise of the connecting shaft 7 will then drive the connecting roller 15 to rise. When the connecting roller 15 rises, it will pull the traction rope 16 to move. Since the end of the traction rope 16 away from the connecting roller 15 is in a fixed state, when the traction rope 16 moves, it will release the wire harness and pull the connecting roller 15 to rotate. The rotation of the connecting roller 15 will drive the connecting shaft 7 to rotate. The rotation of the connecting shaft 7 will eventually drive the second protective plate 6 to swing (the second protective plate 6 swings as shown in the image). Figure 5 (As shown in the swing state), both sets of guide wheels 17 are fixed to the outside of the machine tool 1, and the traction rope 16 is in contact with the two sets of guide wheels 17. The setting of the guide wheels 17 plays a guiding role in the traction direction of the protective plate 2 6, so that it is pulled in the preset direction.

[0027] Furthermore, such as Figure 6 , Figure 7 and Figure 8 As shown, the control assembly includes a second traction rope 18, a fixing plate 19, and a second guide wheel 20. The control assembly is described in detail below: The second traction rope 18 is fixed to the bottom end of the first protective plate 5. When the first protective plate 5 rises, it pulls the second traction rope 18. The fixed plate 19 is fixed to the bottom end of the side plate 10. The end of the second traction rope 18 away from the first protective plate 5 is fixed to the fixed plate 19. When the second traction rope 18 is under force, it will pull the fixed plate 19 simultaneously. At this time, the fixed plate 19 will drive the baffle 9 to move through the side plate 10, so that the baffle 9 moves towards the liquid storage tank 8. When the first protective plate 5 rises to the limit position, the second traction rope 18 just pulls the baffle 9 completely inside the liquid storage tank 8, sealing the internal channel of the liquid storage tank 8 to facilitate the accumulation of coolant and prevent coolant from leaking from the bottom end of the liquid storage tank 8. The second guide wheel 20 is fixed to the outside of the liquid storage tank 8. The second traction rope 18 is in contact with the second guide wheel 20. The setting of the second guide wheel 20 can guide the traction direction of the second traction rope 18, so that it is pulled in the preset direction.

[0028] As one implementation method, such as Figure 8 and Figure 9As shown, a straight groove plate 21 is fixedly connected to the outer side of the side plate 10. When the side plate 10 moves, it will also drive the straight groove plate 21 to move. A square plate 22 is fixedly connected to the outer side of the liquid storage tank 8. A compression spring 23 is fixedly connected between the straight groove plate 21 and the square plate 22. When the straight groove plate 21 moves, it will cooperate with the square plate 22 to squeeze the compression spring 23. When the compression spring 23 is stressed, it will deform and generate elastic potential energy. When the workpiece is finished and falls into the liquid storage tank 8, the protective plate 5 moves down to reset. At this time, the pulling of the traction rope 18 by the protective plate 5 ends, and the compression spring 23 will generate elastic potential energy to push the straight groove plate 21 to move in the opposite direction and reset. The straight groove plate 21 then drives the baffle 9 to reset through the side plate 10. At this time, the baffle 9 releases the seal on the inside of the liquid storage tank 8, and the accumulated coolant can flow down the bottom of the liquid storage tank 8 (the bottom of the liquid storage tank 8 is similar to a filter screen structure), exposing the workpiece so that it can be taken out after cooling.

[0029] Furthermore, such as Figure 7 and Figure 9 An overflow hole is provided on the outside of the liquid storage tank 8. When the baffle 9 closes the internal channel of the liquid storage tank 8, if too much coolant accumulates inside the liquid storage tank 8, it will flow into the overflow hole. A guide pipe 24 is installed inside the overflow hole, and the coolant then flows to a designated location through the guide pipe 24, thus avoiding waste of coolant.

[0030] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, three sets of arc springs 25 are fixed to the outer sides of the second protective plate 6 and the first protective plate 5. When the first traction rope 16 pulls the connecting roller 15 to rotate, causing the second protective plate 6 to swing, the second protective plate 6 will cooperate with the first protective plate 5 to squeeze the arc springs 25, causing the arc springs 25 to deform under force and generate elastic potential energy. When the first traction rope 16 releases the pull on the connecting roller 15, that is, when the first protective plate 5 moves down, the arc springs 25 will release elastic potential energy, pushing the second protective plate 6 to swing back and reset, thus avoiding the situation where the second protective plate 6 will collide with the clamping end 2 if it moves down directly in an inclined state.

[0031] As one implementation method, such as Figure 5 and Figure 6 As shown, a limiting plate 26 is fixed to the side of the second protective plate 6 away from the arc spring 25. When the second protective plate 6 swings back to reset, the second protective plate 6 will synchronously drive the limiting plate 26 to swing. The limiting plate 26 is in contact with the outer side of the first protective plate 5. Finally, when the limiting plate 26 swings and hits the first protective plate 5, the reset of the second protective plate 6 stops, thereby ensuring that the second protective plate 6 and the first protective plate 5 are in a vertical state and avoiding the situation of the second protective plate 6 resetting too much.

[0032] Furthermore, such as Figure 9As shown, a blower 27 is installed inside the machine tool 1. The output end of the blower 27 is connected to an air supply pipe 28. When the blower 27 is running, it blows outside air into the air supply pipe 28. The end of the air supply pipe 28 away from the blower 27 passes through the liquid storage tank 8 and extends into the liquid storage tank 8. Finally, the air is blown into the liquid storage tank 8 in the form of air bubbles. The air bubbles rise under the action of buoyancy and stir the surrounding liquid during the rise, forming local eddies and circulation, thereby accelerating the cooling of the workpiece by the liquid. A one-way valve is installed inside the air supply pipe 28. The one-way valve can prevent the liquid inside the liquid storage tank 8 from flowing back into the air supply pipe 28.

[0033] A method for manufacturing a test sleeve for compressive deformation nuts, the method comprising the following steps: S1. Protection and preparation: After the workpiece is clamped at the clamping end 2, the hydraulic cylinder 12 is started to drive the protective plate 5 to rise. It is linked with the connecting roller 15 through the traction rope 16, so that the protective plate 6 swings and closes to form an enclosure. At the same time, the protective plate 5 is linked with the side plate 10 through the traction rope 18 to pull the baffle 9 into the liquid storage tank 8 to seal the bottom. S2, Machining and Liquid Collection: Start the motor and moving module 4, the milling cutter 3 turns the rotating workpiece, and the sprayed coolant falls into the storage tank 8 for storage. S3. Dropping and cooling: After the workpiece is cut off, it falls into the coolant in the storage tank 8 to buffer and cool down. The blower 27 is started to blow air into the storage tank 8 through the air pipe 28 to enhance cooling. S4. Reset and drain: Hydraulic cylinder 12 retracts, and protective plates 5 and 6 are reset under the action of arc spring 25. At the same time, compression spring 23 pushes baffle 9 to reset and open the bottom of liquid storage tank 8, draining the coolant and allowing the workpiece to be removed.

[0034] In this embodiment, after the workpiece is clamped at the clamping end 2, the hydraulic cylinder 12 is activated. Its output end pushes the connecting frame 13 upward along the slide groove 14, thereby causing the protective plates 5 on both sides to rise synchronously. When the protective plate 5 rises, on the one hand, it drives the protective plate 6 upward through the connecting shaft 7, and on the other hand, the connecting roller 15 fixed to the connecting shaft 7 moves upward accordingly. Since the other end of the traction rope 16 wound on the connecting roller 15 is fixed and guided by the guide wheel 17, the upward movement will release the traction rope 16 and pull the connecting roller 15 to rotate. The protective plates 6 on both sides are driven by the connecting shaft 7 to swing and close towards the workpiece. During this process, the arc spring 25 is compressed, and the protective plate 5 and the protective plate 6 together form an enclosure to prevent iron filings from flying. At the same time, the rise of the protective plate 5 is guided by the guide wheel 20 through the traction rope 18 at its bottom end, which pulls the fixed plate 19 and the side plate 10 to move, so that the side plate 10 slides along the guide rod 11, thereby pulling the baffle 9 completely into the liquid storage tank 8 to seal its bottom channel. During this process, the compression spring 23 is compressed, and the protective plate 5 and the protective plate 6 together form an enclosure to prevent iron filings from flying. After the protective plate 26 is in place and the liquid storage tank 8 is closed, the motor inside the machining tool 1 drives the clamping end 2 to rotate the workpiece. The moving module 4 controls the milling cutter 3 to turn the workpiece. Coolant is sprayed to cool it down and falls into the liquid storage tank 8 for storage. When the workpiece is cut off and falls after processing, it falls into the coolant in the liquid storage tank 8. The liquid's buffering effect prevents impact and allows for rapid cooling. At this time, the blower 27 can be started to blow air into the liquid storage tank 8 through the air supply pipe 28 (the air supply pipe 28 is equipped with a one-way valve to prevent backflow). The air bubbles agitate the liquid to... After accelerated cooling and completion of the operation, hydraulic cylinder 12 retracts, protective plate 5 descends, releasing the tension on traction rope 16 and traction rope 18. Compression spring 23 releases its elastic potential energy, pushing straight groove plate 21 and side plate 10 to reset. Baffle 9 moves out, opening the bottom channel of liquid tank 8 and draining the coolant for part removal. At the same time, arc spring 25 pushes protective plate 6 to swing back and reset until the limiting plate 26 on it contacts the outside of protective plate 5, ensuring that protective plate 6 returns to a vertical position. At this point, all mechanisms are reset, ready for the next cycle.
