Description

Technical Field

[0001] This invention relates to the field of automated assembly, and more particularly to a wire thread insert installation punching device. Background Technology

[0002] Wire thread inserts, as high-strength and high-wear-resistant thread repair and reinforcement components, are widely used in fields with extremely high requirements for the reliability of threaded connections, such as aviation, aerospace, automotive, shipbuilding, and precision instruments. The installation process typically involves inserting the insert into a pre-machined threaded hole and then removing the installation shank at the end to form a complete internal thread, ensuring smooth and interference-free threading after installation.

[0003] Currently, the installation and removal of the installation shank of wire thread inserts mainly rely on manual labor or semi-automatic tools. Traditional manual installation methods typically involve the following steps: First, the operator uses a manual installation tool (such as a simple wrench or socket) to screw the wire thread insert into the pilot hole; then, a special breaking tool (such as a punch or striking rod) is used to strike the fracture groove of the installation shank to break it apart. This method has significant drawbacks: First, the installation force, alignment angle, and striking force are difficult to control precisely during manual operation, easily leading to deformation, skipped threads, or improper installation of the insert, affecting the thread's load-bearing capacity and accuracy; second, the breaking process of the installation shank requires additional tools and steps, and the impact and debris generated by the striking may damage the insert body, workpiece threads, or surrounding structures, posing quality risks; third, the entire process is inefficient, highly dependent on the operator's skill and proficiency, labor-intensive, and detrimental to the consistency of mass production and the integration of automated production lines.

[0004] To address some of these issues, semi-automatic installation tools, such as pneumatic or electric threaded insert installation guns, have emerged on the market. These tools can provide relatively consistent screw-in torque, improving installation efficiency. However, these devices are typically limited to screw-in installation; after installation, the operator still needs to manually or with the aid of another device perform the cutting operation. This separation of "installation" and "cutting" processes not only fails to achieve true automation but also requires equipment switching and repeated workpiece positioning, increasing production cycle time and process complexity. Furthermore, it cannot avoid the alignment errors and damage risks that may be introduced during secondary operations.

[0005] In summary, existing technologies lack a device that can integrate and automate the precise installation of wire thread inserts with the reliable breaking of the installation shank. Designing a specialized device with high integration and automation, capable of continuously performing the "installation-breaking" action while ensuring installation quality, improving production efficiency, and reducing operational difficulty, has become a pressing technical problem in this field. Summary of the Invention

[0006] To address the technical problems existing in the prior art, this invention provides a wire thread insert installation punching device. The technical solution is as follows: A wire thread insert installation punching device, comprising: A support member, which is set on the ground, includes a first support member and a pushing member. The first support member is on the ground and is used to provide an upward thrust. The pushing member pushes the broken mounting handle backward and separates it on the first support member. The first punching component is disposed on the first support component. The first punching component includes an electromagnetic component and a second punching component. The electromagnetic component provides an electromagnetic magnetic field to the second punching component on the first support component. The second punching component is on the first support component and is used to punch off the installation handle of the wire thread sleeve installed in the threaded hole, and magnetically pull the punched installation handle into the first support component and push it by the pushing component. An installation component is disposed on the second punched part. The installation component includes a threaded sleeve installation component and an installation power component. The threaded sleeve installation component is circumferentially driven on the second punched part to rotate and install the wire threaded sleeve loaded on the threaded sleeve installation component into the threaded hole. The installation power component drives the second punched part circumferentially.

[0007] Preferably, the first support includes a first support base, a first linear actuator, and a second support base. The first support base provides support on the ground, and the first linear actuator drives the connected second support base to move up and down on the first support base.

[0008] Preferably, the electromagnetic component includes a guide tube and an electromagnetic coil, both of which are embedded in a mounting groove on the second support base, and the guide tube is located in the inner circle of the electromagnetic coil.

[0009] Preferably, the second breaking member includes a support tube, a third linear actuator, and a breaking shaft. One end of the support tube is connected to the second support base, the third linear actuator is mounted on the other end of the support tube, one end of the breaking shaft is rotatably connected to the telescopic end of the third linear actuator, and the other end of the breaking shaft passes through the guide tube.

[0010] Preferably, the threaded sleeve mounting component includes a threaded sleeve mounting cylinder and a first spring. The threaded sleeve mounting cylinder is axially sliding and circumferentially locked onto the other end of the break-off shaft, and the threaded sleeve mounting cylinder is located inside the guide tube. The first spring is sleeved on an annular groove on one side wall of the break-off shaft, and the top end of the first spring is connected to a push plate on the inner wall of the threaded sleeve mounting cylinder.

[0011] Preferably, the installation power component includes a protective shell, a rotating shaft, a magnet, and a stator. The protective shell is fitted through the support tube, the rotating shaft is rotatably embedded in the protective shell within the support tube, and the rotating shaft is axially sliding and circumferentially locked and fitted outside the break-off shaft. The magnet is disposed on the outer wall of the rotating shaft, the stator is embedded in the protective shell, and the stator is fitted and sleeved outside the rotating shaft.

[0012] Preferably, the system further includes a sorting and feeding component, which is located on the ground and provides the wire thread inserts to be installed to the mounting component. The sorting and feeding component includes a directional sorting component and a feeding component. The directional sorting component, located on the ground, orients and sorts a plurality of wire thread inserts placed inside it and then conveys them to the connected feeding component. The feeding component, on the directional sorting component, transfers the conveyed wire thread inserts to a position directly above the mounting component, facilitating the loading of the wire thread inserts onto the thread insert mounting cylinder. Preferably, the feeding component includes a second support, a third support, and a clamping and feeding component. The second support is rotatably mounted on a support platform on the bottom surface. The third support moves along the second support and drives the connected clamping and feeding component to rotate circumferentially. The clamping and feeding component moves along the third support and is used to clamp the wire thread sleeve fed by the directional sorting component and move the wire thread sleeve to directly above the thread sleeve mounting component, so as to facilitate the loading of the wire thread sleeve onto the thread sleeve mounting cylinder.

[0013] Preferably, the third support member includes a support block, a rotating tube, a second rotating power member, and a rotating seat. One side of the support block is disposed on the second support member. One end of the rotating tube rotates through a rotating through hole on the support block. The second rotating power member is connected to the rotating tube on the support block. One end face of the rotating seat is disposed on one end of the rotating tube and moves accordingly.

[0014] Preferably, the clamping and feeding component includes clamping claws, a cylinder, and a second spring. One end of the clamping claw is slidably disposed in a sliding groove on the other end face of the rotating seat. Two clamping claws are symmetrically distributed in the sliding groove for clamping the fed wire thread sleeve. The cylinder is connected to both clamping claws on the rotating seat to simultaneously drive the two clamping claws to unfold. The second spring is connected to both clamping claws to simultaneously pull the two clamping claws to clamp.

[0015] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: (1) The wire thread sleeve installation punching device of the present invention has a high degree of integration and automation, high production efficiency and consistency, effectively ensuring installation quality and product reliability, and significant comprehensive economic benefits; (2) The wire thread insert installation punching device of the present invention integrates the first punching part and the installation part into one unit, so that the two core processes of screwing in the wire thread insert and punching the installation handle can be completed continuously and automatically on one machine. This completely changes the traditional process where the two processes are separated, tools need to be changed and multiple operations are required. It significantly simplifies the operation process and eliminates the time waste and repeated positioning errors caused by process conversion. In addition, the fully automated "installation-punching" cycle operation greatly shortens the processing time of a single workpiece. The equipment is driven by a program or control system, which ensures the high consistency of the processing of each wire thread insert and significantly improves the overall production efficiency. (3) The wire thread insert installation punching device of the present invention, by integrating the first punching part and the installation part, can provide precise and controllable screwing torque and speed, ensuring that the wire thread insert is embedded in the bottom hole with the correct posture and depth, effectively avoiding problems such as tilting, skipping teeth or improper installation that may occur during manual installation; and the first punching part can apply precise, vertical and controllable impact to the fracture groove of the installation shank, ensuring successful punching in one go, with a flat fracture surface, avoiding the risk of failure to punch, deformation of the thread insert or damage to the internal thread of the workpiece caused by uneven force or incorrect direction of manual hammering, thus improving the reliability of the threaded connection from the root.

[0022] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] according to Figures 1-15 As shown, a wire thread insert installation punching device includes a support member, a first punching member, an installation member, and a sorting and feeding member. The support member is fixedly installed on the ground at a predetermined position. The first punching member is disposed on the support member and is used to punch off and remove the installation shank of the wire thread insert 1 installed in the threaded hole. The installation member is disposed on the first punching member and is used to install the wire thread insert 1 in the threaded hole. The sorting and feeding member is disposed on the ground and is used to provide the wire thread insert 1 to be installed to the installation member.

[0024] The support structure includes a first support member and a pushing member. The first support member is disposed on the ground and provides an upward thrust. The pushing member is disposed on the first support member and is used to push and collect the mounting handle removed after the first punching member is broken. The first support member includes a first support base 2, a first linear actuator 3, and a second support base 4. The first support base 2 is fixedly disposed on the ground to provide support. The first linear actuator 3 drives the connected second support base 4 to move up and down on the first support base 2. Alternatively, the first linear actuator 3 is a multi-position cylinder. The second support base 4 is mounted on the telescopic end of the first linear actuator 3 via a first connecting seat 5.

[0025] The second support base 4 is provided with a mounting groove, a handle hole 6, and a mounting tube 7. The mounting groove is a circular groove on the bottom surface of the second support base 4 and is used to install the first punching member. The handle hole 6 is horizontally located on the second support base 4 above the mounting groove, and the bottom surface of the handle hole 6 communicates with the first through hole on the bottom surface of the mounting groove for installing the pusher member. A mounting cover 8 is detachably installed on the opening of the mounting groove. One end of the mounting tube 7 is vertically disposed on the top surface of the second support base 4, and one end of the mounting tube 7 is vertically connected to the handle hole 6, so that the pusher member can pass upward.

[0026] Furthermore, a handle guide tube 9 is installed downward through one end of the handle hole 6 to discharge the broken handle downwards. Alternatively, an air jet hole 10 is provided through one end of the handle hole 6, and the free end of the air jet hole 10 is connected to an air jet pipe to blow high-pressure gas into the handle hole 6 to blow the handle inside the handle hole 6 into the handle guide tube 9.

[0027] The pushing component includes a pushing shaft 11 and a second linear actuator 12. One end of the pushing shaft 11 is axially slidably fitted into the other end of the handle hole 6. The second linear actuator 12 is connected to the first connecting seat 5 via a second connecting seat 13, and the telescopic end of the second linear actuator 12 is connected to the other end of the pushing shaft 11. When the second linear actuator 12 extends, it drives the pushing shaft 11 to the left, thereby pushing the mounting handle in the handle hole 6 toward the handle guide tube 9. Combined with the high-pressure gas ejected from the jet hole 10, the mounting handle is smoothly delivered into the handle guide tube 9.

[0028] The first punching component includes an electromagnetic component and a second punching component. The electromagnetic component is disposed on the first support component to provide an electromagnetic magnetic field for the second punching component. The second punching component is disposed on the first support component and is used to punch off the mounting shank of the wire thread sleeve 1 installed in the threaded hole, and to magnetically pull the punched mounting shank into the shank hole 6.

[0029] The electromagnetic component includes a guide tube 14 and an electromagnetic coil 15. One end of the guide tube 14 is embedded in the first through hole, and the other end of the guide tube 14 is fixedly embedded in the second through hole on the mounting cover 8. The axis of the guide tube 14 coincides with the axis of the mounting tube 7. The electromagnetic coil 15 is embedded in the mounting groove to provide an electromagnetic magnetic field for the second punching component as needed.

[0030] The second punching component includes a support tube 16, a third linear actuator 17, and a punching shaft 18. One end of the support tube 16 is connected to the mounting cover 8. The third linear actuator 17 is mounted on the other end of the support tube 16, and the axis of the third linear actuator 17 coincides with the axis of the guide tube 14. One end of the punching shaft 18 is rotatably connected to the telescopic end of the third linear actuator 17, and the other end of the punching shaft 18 passes through the guide tube 14. The diameter of the punching shaft 18 is smaller than the inner diameter of the guide tube 14.

[0031] Furthermore, a connecting shaft 19 is connected to the telescopic end of the third linear actuator 17. The free end of the connecting shaft 19 has a larger diameter and rotatably penetrates into a connecting groove on one end face of the break-off shaft 18. A pressure cap is detachably installed on one end face of the break-off shaft 18. The pressure cap is in the shape of a circular ring plate, and the inner diameter of the pressure cap is smaller than the diameter of the free end of the connecting shaft 19. Alternatively, thrust ball bearings are provided between the free end face of the connecting shaft 19 and the bottom surface of the connecting groove, and between the free end of the connecting shaft 19 and the pressure cap, to facilitate circumferential rotation of the break-off shaft 18 at the telescopic end of the third linear actuator 17.

[0032] Alternatively, a telescopic shaft 20 is provided on the other end face of the punched shaft 18. One end of the telescopic shaft 20 has a smaller diameter than the other end. One end of the telescopic shaft 20 is axially slidably fitted into a telescopic hole on the other end face of the punched shaft 18, and a first slider (the length of the first slider is less than the length of the telescopic hole) on the side wall of one end of the telescopic shaft 20 is fitted into a first groove on the inner wall of the telescopic hole. A detachable and fastened annular plate is installed on the other end of the punched shaft 18 to limit the axial sliding distance of one end of the telescopic shaft 20 within the telescopic hole, preventing the telescopic shaft 20 from slipping out of the telescopic hole. This facilitates the suction and pulling of the punched mounting handle into the handle hole 6. The third linear actuator 17 is a multi-position cylinder or an electric push rod. Furthermore, a first slot 21 is provided on the other end face of the telescopic shaft 20 (when the telescopic shaft 20 is not provided on the other end face of the broken shaft 18, the first slot 21 is provided on the other end face of the broken shaft 18), the first slot 21 is used to fit onto the mounting handle of the wire thread sleeve 1. The height of the top surface of the telescopic shaft 20 is not less than the height of the top surface of the thread sleeve mounting cylinder. When the telescopic shaft 20 is not provided on the other end face of the broken shaft 18, the height of the other end face of the broken shaft 18 is not less than the height of the top surface of the mounting cylinder, to prevent the mounting handle magnetically attracted by the top of the broken shaft 18 or the top of the telescopic shaft 20 from being pushed off by the top of the thread sleeve mounting cylinder.

[0033] The mounting component includes a threaded sleeve mounting component and a mounting power component. The threaded sleeve mounting component is mounted on the punching shaft 18 and is driven circumferentially by the punching shaft 18 to screw the wire threaded sleeve 1 loaded on it into the threaded hole. The mounting power component is mounted on the support tube 16 and provides power for the circumferential rotation of the punching shaft 18.

[0034] The threaded sleeve mounting component includes a threaded sleeve mounting cylinder 22 and a first spring 23. The threaded sleeve mounting cylinder 22 is axially sliding and circumferentially locked onto the other end of the break-off shaft 18. The first spring 23 is fitted onto an annular groove 24 on one side wall of the break-off shaft 18, and one end of the first spring 23 is connected to a circular push plate 25 on the inner wall of the threaded sleeve mounting cylinder 22.

[0035] The outer wall of the threaded sleeve mounting cylinder 22 is provided with an external thread, which mates with the internal thread of the wire threaded sleeve 1 to mount the wire threaded sleeve 1 onto the threaded sleeve mounting cylinder 22. The inner diameter of the threaded sleeve mounting cylinder 22 is not less than the diameter of the punch shaft 18, and the outer diameter of the threaded sleeve mounting cylinder 22 is less than the inner diameter of the guide tube 14 and the mounting tube 7. The outer ring of the push plate 25 is fixedly connected to the inner wall of the threaded sleeve mounting cylinder 22, and the inner ring of the push plate 25 is axially slidably sleeved on the annular groove 24, so that the bottom surface of the push plate 25 is connected to one end of the first spring 23, and the other end of the first spring 23 is connected to the lower side wall of the annular groove 24. The natural length of the first spring 23 is less than the width of the annular groove 24.

[0036] When the break-off shaft 18 extends upward, it will drive the threaded sleeve mounting cylinder 22 to move upward via the first spring 23. When the break-off shaft 18 retracts downward, it will pull the threaded sleeve mounting cylinder 22 downward via gravity and the first spring 23. When the threaded sleeve mounting cylinder 22 is loaded with the wire threaded sleeve 1, the threaded sleeve mounting cylinder 22 can move upward relative to the break-off shaft 18. The second slider 45 on the inner wall of the threaded sleeve mounting cylinder 22 is fitted into the second sliding groove 46 on the side wall of the break-off shaft 18, so that when the break-off shaft 18 rotates, it will drive the threaded sleeve mounting cylinder 22 to rotate circumferentially via the second sliding groove 46 and the second slider 45. A second retaining groove is provided on the upper end face of the threaded sleeve mounting cylinder 22, which is aligned with the first retaining groove 21. The second retaining groove is used to fit onto the mounting handle of the wire threaded sleeve 1.

[0037] The installation power component includes a protective shell 26, a rotating shaft 27, magnets 28, and a stator 29. The protective shell 26 is fitted onto the support tube 16. The rotating shaft 27 is tubular and rotatably fitted into the protective shell 26 within the support tube 16. The rotating shaft 27 is axially sliding and circumferentially locked onto the outside of the break-off shaft 18. The magnets 28 are fixedly disposed on the outer wall of the rotating shaft 27, with multiple magnets 28 evenly distributed circumferentially around the rotating shaft 27. The stator 29 is fixedly fitted into the protective shell 26 and fits onto the outside of the rotating shaft 27. When a current is passed through the coil of the stator 29 to generate a magnetic field, the magnets 28 will drive the rotating shaft 27 to rotate circumferentially within the protective shell 26.

[0038] The third slider 47 on the inner wall of the rotating shaft 27 is fitted into the second slide groove 46, so that when the rotating shaft 27 rotates, the third slider 47 and the second slide groove 46 will drive the punch shaft 18 to rotate circumferentially. The rotating punch shaft 18 will drive the threaded sleeve mounting cylinder 22 to rotate circumferentially. The rotating threaded sleeve mounting cylinder 22 will screw the loaded wire threaded sleeve 1 into the threaded hole, thus completing the installation of the wire threaded sleeve 1.

[0039] Furthermore, a predetermined distance is maintained between the mounting power component and the electromagnetic coil 15 to reduce the impact on the mounting power component when the electromagnetic coil 15 generates a magnetic field. Alternatively, the protective shell 26 is provided with a magnetic field shielding material or a magnetic field shielding cover. The electromagnetic shielding material is one or a combination of low-carbon steel plate, electrical pure iron, or permalloy (the combination constitutes a double-layer shield).

[0040] The sorting and feeding component includes a directional sorting component and a feeding component. The directional sorting component is on the ground and sorts the multiple wire thread sleeves 1 placed inside it in a directional manner before conveying them to the connected feeding component. The feeding component is on the directional sorting component and transfers the conveyed wire thread sleeves 1 to the top of the mounting component, so that the wire thread sleeves 1 can be loaded onto the thread sleeve mounting cylinder 22.

[0041] The orientation and sorting component includes a vibrating sorting component 30 and a positioning tube 31. The vibrating sorting component 30 is mounted on a support platform 32 on the ground and is used to automatically organize multiple randomly placed wire thread sleeves inside it into a uniform and orderly arrangement, and accurately and stably convey them to the positioning tube 31. The positioning tube 31 is mounted on the support platform 32 so that it can be aligned with the feeding component, and is used to vertically convey the wire thread sleeves into the feeding component. Alternatively, the orientation and sorting component can be replaced with manual feeding by the operator (the operator manually adjusts the direction of the wire thread sleeves and then manually places them into the clamping groove).

[0042] The feeding component includes a second support, a third support, and a clamping and feeding component. The second support is rotatably mounted on the support platform 32. The third support moves along the second support and drives the connected clamping and feeding component to rotate circumferentially. The clamping and feeding component moves along the third support and is used to clamp the wire thread sleeve 1 fed by the positioning tube 31 and move the wire thread sleeve 1 directly above the thread sleeve mounting component, so as to facilitate the loading of the wire thread sleeve 1 onto the thread sleeve mounting cylinder 22.

[0043] The second support member includes a support plate 33, a rotating shaft, and a first rotating power member. The support plate 33 is rotatably mounted on the support platform 32. One end of the rotating shaft is vertically fixed to the bottom surface of the support plate 33, and the other end of the rotating shaft rotates through the support platform 32. The first rotating power member is connected to the rotating shaft on the support platform 32 for transmission, so as to drive the support plate 33 to rotate through the rotating shaft.

[0044] The first rotating power component includes a first worm gear, a first worm, and a first motor. The first worm gear is fixedly mounted on the other end of the rotating shaft, the first motor is fixedly mounted on the support platform 32, and the first worm is mounted on the rotating shaft of the first motor, meshing with the first worm gear. Furthermore, a thrust ball bearing is provided between the support plate 33 and the support platform 32, and the first motor is a stepper motor to improve transmission accuracy.

[0045] The third support member includes a support block 34, a rotating tube 35, a second rotating power member 36, and a rotating seat 37. One side of the support block 34 is fixedly disposed on the top surface of the support plate 33, and the axis of the support block 34 is parallel to the radial line of the support plate 33. One end of the rotating tube 35 rotates through the rotating through hole on the support block 34. The second rotating power member 36 is connected to the rotating tube 35 on the support block 34. One end face of the rotating seat 37 is fixedly disposed on one end of the rotating tube 35, and one end of the first air supply through hole on the rotating seat 37 communicates with one end of the rotating tube 35.

[0046] The second rotating power component 36 includes a second motor, a second worm gear, and a second worm wheel. The second motor is mounted on one end of the support block 34 via a mounting base. The second worm gear is mounted on the shaft of the second motor. The second worm wheel is fixedly fitted onto the side wall of the other end of the rotating tube 35, and meshes with the second worm gear. Furthermore, a bearing is provided between the rotating tube 35 and the rotating through hole to enable the rotating tube 35 to rotate circumferentially within the rotating through hole. The second motor is a stepper motor to improve transmission accuracy.

[0047] The clamping and feeding component includes clamping claws 38, a cylinder, and a second spring 39. One end of the clamping claw 38 is slidably disposed in a sliding groove on the other end face of the rotating seat 37 (the bottom surface of the sliding groove communicates with the first air supply hole). The two clamping claws 38 are symmetrically distributed in the sliding groove for clamping the wire thread sleeve 1 that is being fed in. The cylinder is connected to both clamping claws 38 on the rotating seat 37 to drive both clamping claws 38 to unfold simultaneously. The second spring 39 is connected to both clamping claws 38 to pull both clamping claws 38 to clamp simultaneously.

[0048] The thickness of one end of the clamping claw 38 is less than the thickness of the other end of the clamping claw 38. The space formed by the two clamping claws 38 at one end within the sliding groove is used to install the cylinder component and the second spring 39. A clamping groove is provided on the side wall of the other end of the clamping claw 38. The clamping groove is arc-shaped, and its axial length is less than the vertical width of the clamping claw 38, so that one end of the clamping groove is connected to the top surface of the clamping claw 38, while the other end is not connected to the bottom surface of the clamping claw 38 (when the two clamping claws 38 are opened to a predetermined width, the non-connected bottom surface of the clamping groove is used to receive the wire thread sleeve 1 delivered by the positioning tube 31). The central angle of the clamping groove is less than 180 degrees.

[0049] The cylinder assembly includes a cylinder body 40, pistons 41, piston rods, and a gas source processing element. The cylinder body 40 is connected to the bottom surface of the sliding groove, and the second gas supply hole at the middle position of the cylinder body 40 communicates with the first gas supply hole. The two pistons 41 are slidably and sealingly embedded in the tubes at both ends of the cylinder body 40. One end of each of the two piston rods passes through the cylinder body covers at both ends of the cylinder body 40 and is fixedly connected to the pistons 41. The other ends of the two piston rods are connected to the two clamping claws 38. The gas source processing element is rotatably and sealingly connected to the other end of the rotating tube 35 through a high-pressure hose 43 and a rotary joint 44, for supplying driving gas into the cylinder body 40 through the rotating tube 35 to drive the two piston rods to slide outward simultaneously, thereby simultaneously pushing the two clamping claws 38 to unfold outward. The cylinder assembly, through an automatic exhaust function and the action of the second spring 39, causes the two clamping claws 38 to move towards each other simultaneously to clamp the wire thread sleeve 1.

[0050] The method of using the wire thread insert installation punching device includes: S1: By adjusting the first rotating power component and the second rotating power component 36, the clamping groove is rotated to be directly below the positioning tube 31, and one end of the clamping groove is facing upward (at this time, the two clamping claws 38 are driven to unfold by the cylinder component). S2: The wire thread sleeve 1 (the wire thread sleeve 1 with the mounting shank facing forward) with the adjusted direction is conveyed to the positioning tube 31 by the vibration sorting component 30, and then enters the two positioning slots from the positioning tube 31; S3: Activate the automatic exhaust function of the cylinder component, and simultaneously pull the two clamping claws 38 through the second spring 39 to clamp the wire thread sleeve 1; S4: Activate the first and second rotating power components 36 to drive the clamping claw 38 to rotate in the forward plane and circumferential direction, so that the clamping groove is located directly above the mounting tube 7, and one end of the clamping groove faces downward (e.g., Figure 11 (as shown) S5: The third linear actuator 17 is activated to extend, driving the other end of the punching shaft 18 (or the telescopic shaft 20 on the other end of the punching shaft 18) to move upward and insert into the wire thread sleeve 1 (the length of the other end of the punching shaft 18 inserted into the wire thread sleeve 1 is less than half the length of the wire thread sleeve). At this time, the top end of the external thread of the thread sleeve mounting cylinder 22 is pushed against the bottom end of the internal thread of the wire thread sleeve 1 by the first spring 23. S6: Start the installation power component to drive the punching shaft 18 to rotate in the forward direction. The punching shaft 18 drives the threaded sleeve mounting cylinder 22 to rotate in the forward direction. The rotating threaded sleeve mounting cylinder 22 is screwed into the wire threaded sleeve 1, completing the loading of the wire threaded sleeve 1. S7: Initiate the two clamping claws 38 to unfold, and then initiate the third linear actuator 17 to shorten, so that the wire thread sleeve 1 is completely disengaged from the clamping groove; S8: Repeat step S1, and then start the first linear actuator 3 to extend (so that the height of the mounting tube 7 is much greater than the clamping claw 38), so that the top end of the mounting tube 7 is aligned with the outside of the threaded hole (the threaded hole is the threaded hole on the rear longitudinal beam of the car where the wire thread sleeve 1 needs to be installed, the rear longitudinal beam is clamped and moved by the robotic arm to directly above the second support 4, and the axis of the threaded hole coincides with the axis of the mounting tube 7). S9: The third linear actuator 17 is activated to extend (so that the punching shaft 18 or the telescopic shaft 20 is inserted into the threaded hole to a predetermined length). The punching shaft 18 and the threaded sleeve mounting sleeve 22 drive the top of the wire threaded sleeve 1 to abut against the bottom port of the threaded hole (at this time, the length of the punching shaft 18 inserted into the threaded hole is not less than the length of three turns of thread and not more than half the length of the wire threaded sleeve 1). S10: Start the installation power component to rotate, rotate the wire thread sleeve 1 into the threaded hole, and then stop the installation power component from rotating; S11: Direct current is passed into the electromagnetic coil 15 to generate a magnetic field, thereby making the top end of the break-off shaft 18 or the top end of the telescopic shaft 20 magnetic. Then, the third linear actuator 17 is activated to continue to extend, and the mounting handle is broken off from the wire thread sleeve 1 and adsorbed onto the top end of the break-off shaft 18 or the top end of the telescopic shaft 20 through the break-off shaft 18 or the telescopic shaft 20. S12: Start the installation power component to drive the threaded sleeve mounting cylinder 22 to rotate in the opposite direction (control the reverse rotation speed of the installation power component to make the reverse rotation speed of the threaded sleeve mounting cylinder 22 slower, to prevent the installation handle from being thrown off the punching shaft 18 or the telescopic shaft 20), and rotate the threaded sleeve mounting cylinder 22 downward from the wire threaded sleeve 1 to exit (at this time, the threaded sleeve mounting cylinder 22 compresses the first spring 23, moves downward relative to the punching shaft 18, and exits the wire threaded sleeve 1), and stop the rotation of the installation power component after it has completely exited; S13: The third linear actuator 17 is activated to shorten, causing the top end of the punching shaft 18 to exit from the threaded hole, and driving the top end of the punching end and the threaded sleeve mounting cylinder 22 to retract into the shank hole 6; then the mounting power component is activated to rotate rapidly (at this time, the electromagnetic coil 15 reduces the energizing current intensity or cuts off the power), causing the mounting handle to be thrown from the top end of the punching shaft 18 or the telescopic shaft 20 into the shank hole 6; S14: The second linear actuator 12 is activated to push the mounting handle into the handle guide tube 9 via the push shaft 11 (in conjunction with the air jet 10 blowing it up), thus completing the separation of the mounting handle.

[0051] It should be noted that this embodiment is applicable to the threaded holes on the rear longitudinal beam of an automobile where the wire thread insert 1 needs to be installed, and the wire thread insert 1 installation punching device is designed accordingly. However, the wire thread insert 1 installation punching device can also be applied to all workpieces with the wire thread insert 1 installed upwards, and also to all workpieces with the wire thread insert 1 installed downwards, depending on future needs (in this case, the first linear actuator 3 is changed to push downwards, and the second rotational power component 36 does not need to circumferentially drive one end of the clamping groove to rotate upwards and downwards).

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
