Description

Technical Field

[0001] This invention relates to the technical field of self-tapping screw sleeve processing equipment, specifically to an automatic continuous processing equipment for self-tapping screw sleeves. Background Technology

[0002] Self-tapping inserts, also known as self-tapping thread inserts, are fasteners with internal and external threads. They can be embedded in relatively soft materials such as plastics, aluminum alloys, cast iron, and copper to form high-strength internal threaded holes, and can also repair damaged internal threads. Their key feature is their self-tapping capability, eliminating the need for pre-tapping the base material during installation, thus saving costs and improving installation efficiency.

[0003] In the existing technology, most conventional self-tapping screw sleeve processing equipment adopts a manual single-piece feeding mode. Operators need to place the blanks one by one at the processing station, which cannot achieve continuous automatic feeding of blanks. Not only is the labor cost high, but the feeding rhythm is also difficult to match the machine tool processing rhythm. Frequent feeding interruptions disrupt the production continuity, thereby reducing the overall processing efficiency. Summary of the Invention

Through the fixed setting, the workpiece is clamped and limited, ensuring that the workpiece is reliably positioned and not easily deviated during processing. The rinsing mechanism includes a water pump pipe, with a water storage frame fixedly connected to the end of the water pump pipe. A filter screen is fixedly connected to the inner wall of the water storage frame. The filter screen separates the processing waste from the water, allowing the waste to fall onto the surface of the filter screen for easy cleaning by workers.

[0006] Furthermore, the top of the conveyor frame is provided with an elongated hole, the upper surface of the conveyor frame is provided with a feed hole, the two sides of the conveyor frame are provided with moving grooves, and the bottom of the feed slide plate is in contact with the surface of the base plate.

[0007] Furthermore, the feeding mechanism includes an electric telescopic rod, the output end of which is fixedly connected to a contact bending plate, the inner wall of the conveyor frame is fixedly connected to a guide tube, and the end of the slide rod away from the moving ring is fixedly connected to a return spring.

[0008] Furthermore, the surface of the electric telescopic rod is fixedly connected to the end of the conveyor frame, the output end of the electric telescopic rod is in contact with the inner wall of the guide tube, the end of the slide rod is fixedly connected to the end of the return spring, the end of the return spring away from the slide rod is fixedly connected to the inner wall of the moving groove, and the surface of the slide rod is slidably connected to the inner wall of the moving groove.

[0009] Furthermore, the fixing mechanism includes a turntable, a toothed ring is fixedly connected to the outer wall of the turntable, a guide groove is formed on the surface of the turntable, a reset elastic rod is fixedly connected to the inner wall of the guide groove, and a toothed disc is fixedly connected to the output end of the motor.

[0010] Furthermore, the inner wall of the turntable is rotatably connected to the outer wall of the guide tube, the inner wall of the guide groove is slidably connected to the end of the moving rod, the end of the reset elastic rod away from the moving rod is fixedly connected to the inner wall of the guide groove, the end of the push rod away from the moving rod is hinged to the inner wall of the slip ring, and the toothed ring and the toothed disc are hinged to each other.

[0011] Furthermore, the rinsing mechanism includes a right-angle plate, a punching machine is fixedly connected to the end of the right-angle plate, a right-angle plate is fixedly connected to the top of the feed slide plate, a cutting machine is fixedly connected to the end of the right-angle plate away from the feed slide plate, a rinsing pipe is fixedly connected to the surface of the right-angle plate, and a rinsing pipe is fixedly connected to the surface of the right-angle plate.

[0012] Furthermore, the end of the right-angle plate away from the punching machine is fixedly connected to the top of the feed slide plate, the ends of the flushing pipe one and the flushing pipe two are fixedly connected to the output end of the water pump, the end of the water pump away from the water storage frame is fixedly connected to the output end of the water pump, and the bottom of the water storage frame is fixedly connected to the surface of the base plate.

[0013] The present invention has the following beneficial effects: This invention uses a guide frame for material storage, combined with an electric telescopic rod and a guide tube to form a feeding mechanism. Workpieces are stored and dropped sequentially by their own weight. The telescopic rod intermittently pushes the blanks to the processing station. With the help of a return spring, the feeding component automatically rebounds and resets. This enables continuous automatic feeding of workpieces without interruption, eliminating the need for manual single-piece feeding, reducing processing standby time, and significantly improving the batch processing efficiency of self-tapping screw inserts.

[0014] This invention utilizes a fixed mechanism that relies on a motor to drive a turntable to rotate via a gear plate and gear ring. Multiple sets of fixed rings are synchronously clamped to the workpiece through a linkage control system using slip rings, push rods, and moving rods. The feeding and clamping mechanisms are linked, ensuring stable workpiece positioning without loosening. The turntable can drive the entire workpiece to rotate for processing, effectively preventing workpiece displacement during drilling and threading processes, improving product dimensional accuracy, and reducing defective product output. After processing, a reset elastic rod drives the fixed rings to automatically release the material, achieving an automated clamping and releasing cycle.

[0015] This invention employs a two-stage separate feeding structure with feed slide one and feed slide two, each equipped with a drilling machine and a cutting machine, to complete the workpiece drilling and external thread cutting processes sequentially. The two processes are completed continuously in one integrated manner, eliminating the need for secondary disassembly and relocation of the workpiece, simplifying the processing flow, and shortening the processing time per piece.

[0016] This invention utilizes a dual-pipeline fixed-point spraying structure through a rinsing mechanism. Rinsing pipe one and rinsing pipe two spray cooling water onto the cutting and drilling stations respectively. This can quickly remove processing heat, reduce tool wear due to high temperatures, and extend tool life. It can also flush away processing waste and prevent debris from splashing. The processing wastewater is filtered through a filter screen and then returned to a water storage frame, where it is pumped out for recycling. Waste residue is left on the filter screen for easy centralized cleaning. This not only improves the workshop working environment but also realizes the recycling of cooling water and saves production water.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8 As shown, the present invention is an automatic continuous processing self-tapping screw sleeve processing equipment, including a base plate 1, a conveyor frame 2 and a guide rail 5 fixedly connected to the surface of the base plate 1, a guide frame 3 fixedly connected to the upper surface of the conveyor frame 2, a motor 4 fixedly connected to the lower surface of the conveyor frame 2, a feed slide plate 6 slidably connected to the surface of the guide rail 5, a groove opened on the surface of the feed slide plate 6, and a second feed slide plate 7 slidably connected to the inner wall of the groove, and also includes; The feeding mechanism 10 includes a moving ring 14, a sliding ring 15 slidably connected to the inner wall of the moving ring 14, and a sliding rod 16 fixedly connected to the surface of the moving ring 14. The fixing mechanism 30 includes a movable rod 35, a push rod 36 is hinged to the surface of the movable rod 35, and a fixing ring 37 is fixedly connected to the end of the movable rod 35. The rinsing mechanism 50 includes a water pump pipe 57, with a water storage frame 58 fixedly connected to the end of the water pump pipe 57, and a filter screen 59 fixedly connected to the inner wall of the water storage frame 58.

[0023] The top of the conveyor frame 2 has an elongated hole, the upper surface of the conveyor frame 2 has a feed hole, and the two sides of the conveyor frame 2 have moving grooves. The bottom of the feeding slide plate 6 contacts the surface of the base plate 1.

[0024] The feeding mechanism 10 includes an electric telescopic rod 11. The output end of the electric telescopic rod 11 is fixedly connected to a contact bending plate 12. The inner wall of the conveyor frame 2 is fixedly connected to a guide tube 13. First, the workpiece is placed horizontally inside the guide frame 3. After the workpiece is placed inside the guide frame 3, it will move down the slope of the guide frame 3. The first workpiece will move into the guide tube 13, and the subsequent workpieces will be blocked by the first workpiece and stay inside the guide frame 3. At this time, the electric telescopic rod 11 is activated to extend and push the workpiece inside the guide tube 13 towards the slip ring 15. While the electric telescopic rod 11 is extending, it will drive the contact bending plate 12 to move towards the slip ring 15. During the movement of the workpiece, it will move to the outside of the guide tube 13. During the movement of the contact bending plate 12, it will contact the surface of the moving ring 14 and push the moving ring 14 towards the feed slide plate 16. The end of the slide rod 16 away from the moving ring 14 is fixedly connected to a return spring 17.

[0025] The surface of the electric telescopic rod 11 is fixedly connected to the end of the conveyor frame 2. The output end of the electric telescopic rod 11 contacts the inner wall of the guide tube 13. The end of the slide rod 16 is fixedly connected to the end of the return spring 17. The end of the return spring 17 away from the slide rod 16 is fixedly connected to the inner wall of the moving groove. The surface of the slide rod 16 is slidably connected to the inner wall of the moving groove. When the moving ring 14 moves, it will drive the slide ring 15 to move towards the feed slide plate 6, and at the same time pull the slide rod 16 to slide towards the feed slide plate 6 on the inner wall of the moving groove. When the slide rod 16 slides, it will squeeze the return spring 17. When squeezed, it will contract in the direction of the feed slide plate 6. After the workpiece is processed, the electric telescopic rod 11 will drive the contact bending plate 12 to reset. The moving ring 14, slip ring 15, and slide rod 16 will be elastically reset to their original positions with the return spring 17. After the electric telescopic rod 11 is reset, the first workpiece is transferred into the guide tube 13. The electric telescopic rod 11 is driven again to push the workpiece along the guide tube 13 to the outside of the tube opening to complete the subsequent processing. This device relies on the cooperation of the guide frame 3 and the electric telescopic rod 11 to realize the continuous automatic feeding and processing of workpieces, eliminating the manual feeding process and greatly improving the workpiece processing efficiency.

[0026] The fixing mechanism 30 includes a turntable 31, with a toothed ring 32 fixedly connected to the outer wall of the turntable 31. A guide groove 33 is provided on the surface of the turntable 31. When the slip ring 15 moves, it drives the end of the push rod 36 to move in the direction of the feed slide plate 6. The other end of the push rod 36 pushes the moving rod 35 to slide in the direction of mutual approach on the inner wall of the guide groove 33. When the moving rod 35 moves, it pushes the reset elastic rod 34 to retract in the direction of mutual approach. When the moving rod 35 moves, it pushes the fixing ring 37 to move in the direction of mutual approach. During the movement of the fixing ring 37, it will contact the surface of the workpiece, thereby clamping and fixing the workpiece. The reset elastic rod 34 is fixedly connected to the inner wall of the guide groove 33. A toothed disc 38 is fixedly connected to the output end of the motor 4.

[0027] The inner wall of the turntable 31 is rotatably connected to the outer wall of the guide tube 13, the inner wall of the guide groove 33 is slidably connected to the end of the moving rod 35, the end of the reset elastic rod 34 away from the moving rod 35 is fixedly connected to the inner wall of the guide groove 33, the end of the push rod 36 away from the moving rod 35 is hinged to the inner wall of the slip ring 15, and the gear ring 32 and the gear disk 38 are hinged to each other. When the workpiece is fixed, the start motor 4 drives the gear disk 38 to rotate. When the gear disk 38 rotates, it will drive the gear ring 32 to rotate. When the gear ring 32 rotates, it will drive the turntable 31 to rotate on the surface of the guide tube 13. When the turntable 31 rotates, it will drive the reset elastic rod 34, the moving rod 35 and the push rod 36 to rotate at the same time. When the push rod 36 rotates, it will drive the slip ring 15 to rotate on the inner wall of the moving ring 14. The three sets of fixed rings 37 effectively form a clamping limit on the workpiece during the operation of the mechanism, ensuring that the workpiece is firmly positioned and not easily deviated during processing.

[0028] The rinsing mechanism 50 includes a right-angle plate 51, with a drilling machine 52 fixedly connected to the end of the right-angle plate 51. A right-angle plate 53 is fixedly connected to the top of the feed slide plate 7. A cutting machine 54 is fixedly connected to the end of the right-angle plate 53 away from the feed slide plate 7. A rinsing pipe 55 is fixedly connected to the surface of the right-angle plate 53, and a rinsing pipe 56 is fixedly connected to the surface of the right-angle plate 51. When the workpiece is clamped and rotated, the feed slide plate 6 is activated, driving the feed slide plate 7, right-angle plate 51, right-angle plate 53, and cutting machine. 54. Rinsing pipe 1 55 and rinsing pipe 2 56 move toward the workpiece. When the punching machine 52 moves, it will contact the end of the workpiece. Then the punching machine 52 will be started to punch holes in the workpiece. After the cutting machine 54 moves into place and is started, the feed slide plate 2 7 will be started to slide in the direction of right angle plate 1 51 on the inner wall of the slide groove. When the feed slide plate 2 7 slides, it will drive right angle plate 2 53 and the cutting machine 54 to move in the direction of right angle plate 1 51, so that the cutting machine 54 contacts the surface of the workpiece and processes it, so that the surface of the workpiece forms threads.

[0029] The end of right-angle plate 51 furthest from the punching machine 52 is fixedly connected to the top of the feed slide plate 6. The ends of flushing pipe 1 55 and flushing pipe 2 56 are fixedly connected to the output end of water pump 8. The end of water suction pipe 57 furthest from the water storage frame 58 is fixedly connected to the output end of water pump 8. The bottom of the water storage frame 58 is fixedly connected to the surface of the base plate 1. While the punching machine 52 and the cutting machine 54 are processing, the water pump 8 is started to draw water from inside the water storage frame 58 through the water suction pipe 57. The drawn water then enters the interior of flushing pipe 1 55 and flushing pipe 2 56 respectively. Water is sprayed onto the processing positions of the drilling machine 52 and the cutting machine 54 to prevent the waste generated during processing from splashing. Finally, the waste will fall onto the surface of the filter screen 59 with the water flow, making it easy for the staff to clean. The water will flow into the water storage frame 58 and can be extracted and reused. The first flushing pipe 55 and the second flushing pipe 56 spray cooling water onto the processing positions of the drilling machine 52 and the cutting machine 54, which can not only prevent the processing debris from splashing, but also allow the processing waste to fall onto the filter screen 59 with the flushing water, making it easy for manual collection and cleaning. The filtered water flows into the water storage frame 58, realizing the recycling and reuse of water resources.

[0030] In use, the workpiece is first placed horizontally inside the guide frame 3. After the workpiece is placed inside the guide frame 3, it will move downwards along the slope of the guide frame 3. The first workpiece will move into the guide tube 13, while subsequent workpieces will be blocked by the first workpiece and stop inside the guide frame 3. At this time, the electric telescopic rod 11 is activated to extend and push the workpiece inside the guide tube 13 towards the slip ring 15. As the electric telescopic rod 11 extends, it will drive the contact bend plate 12 to move towards the slip ring 15. During the movement of the workpiece, it will move to the outside of the guide tube 13. During the movement of the contact bend plate 12, it will contact the surface of the moving ring 14 and push the moving ring 14 towards the feed slide plate 6. During movement, the slip ring 15 moves towards the feed slide plate 6, while simultaneously pulling the slide rod 16 along the inner wall of the moving groove towards the feed slide plate 6. As the slide rod 16 slides, it compresses the return spring 17. When the return spring 17 is compressed, it contracts towards the feed slide plate 6. After the workpiece is processed, the electric telescopic rod 11 drives the contact bend plate 12 to reset. The moving ring 14, slip ring 15, and slide rod 16 return to their original positions due to the elasticity of the return spring 17. After the electric telescopic rod 11 resets, the first workpiece is transferred into the guide tube 13. Driving the electric telescopic rod 11 again pushes the workpiece along the guide tube 13 to the outside of the tube opening, completing subsequent processing. This device relies on the coordinated operation of the guide frame 3 and the electric telescopic rod 11 to achieve the processing... The continuous automatic feeding process eliminates the need for manual loading of each part, significantly improving workpiece processing efficiency. As the slip ring 15 moves, it drives the end of the push rod 36 towards the feed slide plate 16. The other end of the push rod 36 pushes the moving rod 35 to slide closer together on the inner wall of the guide groove 33. During the movement of the moving rod 35, it pushes the return elastic rod 34 to retract closer together. Simultaneously, the moving rod 35 pushes the fixing ring 37 to move closer together. During this movement, the fixing ring 37 contacts the workpiece surface, clamping and fixing the workpiece. Once the workpiece is fixed, the starting motor 4 drives the gear disc 38 to rotate. When the gear disc 38 rotates, it drives the gear ring 32 to rotate. When the gear ring 32 rotates, it carries... The rotating turntable 31 rotates on the surface of the guide tube 13. When the turntable 31 rotates, it drives the reset elastic rod 34, the moving rod 35, and the push rod 36 to rotate simultaneously. When the push rod 36 rotates, it drives the slip ring 15 to rotate on the inner wall of the moving ring 14. The three sets of fixed rings 37 effectively clamp and limit the workpiece during the operation of the mechanism, ensuring that the workpiece is reliably positioned and not easily deviated during processing. When the workpiece is clamped and rotates, the feed slide plate 1 6 is activated, which drives the feed slide plate 2 7, right angle plate 1 51, right angle plate 2 53, cutting machine 54, flushing pipe 1 55, and flushing pipe 2 56 to move towards the workpiece. When the drilling machine 52 moves, it will contact the end of the workpiece, and then the drilling machine 52 will be activated to drill holes in the workpiece. After the cutting machine 54 moves into position and is activated,Then, the feed slide plate 2 7 is started and slides along the inner wall of the chute towards the right-angle plate 1 51. When the feed slide plate 2 7 slides, it will drive the right-angle plate 2 53 and the cutting machine 54 to move towards the right-angle plate 1 51, so that the cutting machine 54 contacts and processes the surface of the workpiece, forming threads on the surface of the workpiece. While the drilling machine 52 and the cutting machine 54 are processing, the water pump 8 is started to draw water from the water storage frame 58 through the water suction pipe 57. The drawn water will then enter the flushing pipe 1 55 and the flushing pipe 2 56 respectively, and then the flushing pipe 1 55 and the flushing pipe 2 56 will spray water respectively. At the processing positions of the drilling machine 52 and the cutting machine 54, the waste generated during processing is prevented from splashing. The waste falls onto the surface of the filter screen 59 with the water flow, facilitating cleaning by workers. The water flows into the water storage frame 58 and can be extracted and reused. Flushing pipes 1 55 and 2 56 spray cooling water onto the processing positions of the drilling machine 52 and the cutting machine 54, respectively. This prevents the splashing of processing debris, and the processing waste falls onto the filter screen 59 with the flushing water, facilitating manual collection and cleaning. The filtered water flows into the water storage frame 58, achieving water resource recycling.
