Description

Technical Field

[0001] This invention relates to the field of elevator metal parts processing equipment technology, specifically to an intelligent elevator metal parts processing device. Background Technology

[0002] With the rapid development of the elevator industry, the market has placed higher demands on the processing precision, efficiency, and product qualification rate of elevator metal parts. Elevator metal parts often require multiple processing steps such as drilling and cutting. They are core components that ensure the stability and safety of elevator operation, and their processing quality directly affects the service life and safety of the elevator. Currently, the industry mostly adopts a step-by-step processing model to complete the entire process of processing elevator metal parts.

[0003] The existing processing equipment has many shortcomings: First, drilling and cutting are mostly independent equipment, requiring manual transfer and positioning of workpieces between different devices, which not only increases labor costs but also easily causes deviations due to secondary positioning, affecting processing accuracy; Second, the workpiece clamping mechanism is poorly designed, and the clamping force cannot be kept stable, which can easily lead to problems such as excessive pressure damaging the workpiece or insufficient pressure causing workpiece displacement, reducing the product qualification rate; Third, burrs are easily generated during the cutting process, requiring an additional grinding process, increasing processing costs, and the cutting efficiency is low, making it difficult to adapt to the needs of mass production; Fourth, the power transmission structure is cumbersome, the coordination of various components is poor, and the equipment operation and maintenance are inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a processing device for intelligent elevator metal parts, which solves the problems of traditional devices such as step-by-step drilling and cutting, poor positioning accuracy, unstable clamping force that easily damages the workpiece, numerous cutting burrs and low efficiency, complex structure and inconvenient maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a processing device for intelligent elevator metal parts, comprising a processing table, wherein a straight cutting groove is formed on one side of the upper surface of the processing table, a fixed bracket is fixedly installed on the side of the upper surface of the processing table near the straight cutting groove, a top plate is fixedly installed on the top of the fixed bracket, a movable plate is movably installed below the top plate, and a cylinder is movably installed at each of the four corners of the movable plate via bearing seats, a drilling bit is fixedly installed at the bottom of each cylinder, a central shaft is movably installed in the middle of the top plate via bearing seats, and a crossbar is fixedly installed at the bottom of the movable plate. Both ends of the frame are movably mounted with rotating frames. Spring plates are fixedly mounted on both sides of the inside of the cross frame, and the ends of the spring plates extend into the interior of the rotating frames on the corresponding sides. Pressure rollers are fixedly mounted on the inner side walls of the rotating frames, and the tops of the pressure rollers abut against the lower surface of the spring plates on the corresponding sides. Connecting rods are movably mounted on the bottom of the rotating frames, and the ends of the connecting rods are movably mounted on the top sides of the positioning pressure blocks. A movable table is movably mounted on the bottom of the processing table near the cutting straight groove through two guide rods. An installation groove is opened in the middle of the movable table, and a cold saw is installed inside the installation groove near the cutting straight groove.

[0006] Two positioning guide rails are fixedly installed on the upper surface of the processing table.

[0007] The top plate has inner rods movably installed at its four corners via bearing seats. Splines are fixedly installed on both sides of the bottom of the inner rods. Keyways are opened on both sides of the inner wall of the cylinder. The outer ends of the splines are movably set on the inner wall of the keyways on the corresponding sides.

[0008] The top of each inner rod extends to the top plate and is fixedly mounted with a driven gear. A geared motor is fixedly mounted on the top plate via a bracket. A drive gear is fixedly mounted on the drive end of the geared motor. The inner ends of each driven gear mesh with the outer diameter of the drive gear. The top of the central shaft is fixedly mounted at the middle of the bottom end of the drive gear.

[0009] A threaded sleeve is fixedly installed in the middle of the movable plate, and a threaded rod is fixedly installed at the bottom of the central shaft, with the outer diameter of the threaded rod threadedly connected to the inside of the threaded sleeve.

[0010] A horizontal shaft is movably mounted in the center of the mounting groove, and a transmission gear is fixedly mounted on the outer diameter of the middle part of the horizontal shaft.

[0011] A chuck is fixedly installed on the outer diameter of the horizontal shaft near the cold saw cutting machine. A top frame is fixedly installed at the bottom of the end of the cold saw cutting machine near the transmission gear. Several hemispherical protrusions are fixedly installed on the top of the top frame and on the outer diameter of the transmission gear. Both ends of the cold saw cutting machine are connected to the inner wall of the mounting groove by tension springs.

[0012] A rack plate is fixedly installed on the bottom end of the processing table near the movable table, and the bottom end of the rack plate is meshed with the top end of the transmission gear.

[0013] A lead screw is movably installed on the side of the machining table near the movable table, and the outer diameter of the middle part of the lead screw is threaded to one side of the movable table. A stepper motor is fixedly installed on one side of the machining table, and the drive end of the stepper motor is fixedly installed on one end of the lead screw.

[0014] This invention provides a processing device for metal parts of intelligent elevators. It has the following beneficial effects:

[0015] 1. This invention utilizes the coordinated operation of a spring plate, pressure roller, rotating frame, and connecting rod. During the process of the positioning block clamping the workpiece, the pressure roller rotates with the rotating frame and slides relative to the surface of the spring plate, dynamically compensating for changes in the elastic force during the bending of the spring plate. This ensures that the clamping force of the positioning block on the workpiece remains constant. This avoids workpiece displacement and reduced machining accuracy due to insufficient pressure, while also preventing surface damage and deformation caused by excessive pressure. It is well-suited to the high-precision, low-damage machining requirements of elevator metal parts.

[0016] 2. The drilling mechanism of this invention drives the active gear to rotate via a reduction motor, which in turn drives the driven gears around it and the inner rod to rotate synchronously. The inner rod, through the limiting fit of splines and keyways, drives the cylinder and drilling bits to rotate at high speed and synchronously, ensuring that the speed of multiple drilling bits is consistent and their movements are synchronized. At the same time, the movable plate achieves smooth lifting and lowering through the threaded fit of the threaded rod and the threaded sleeve, ensuring uniform drilling depth and accurate hole position, thus meeting the stringent requirements of drilling accuracy for elevator metal parts.

[0017] 3. During the cutting process of this invention, the stepper motor drives the lead screw to rotate, which, in conjunction with the guide rod for limiting, drives the movable table and the cold saw cutting machine to move smoothly along the cutting groove, achieving precise cutting. At the same time, when the movable table moves, the transmission gear meshes with the rack plate, driving the chuck to rotate. The chuck engages with the hemispherical protrusion on the top frame through misalignment, and with the action of the tension spring, the cold saw cutting machine generates high-frequency up-and-down vibration. The vibration and the high-speed rotation of the saw blade work together to not only reduce the pressure required for cutting and speed up the cutting speed, but also to simultaneously grind the cut, effectively reducing cutting burrs and improving the flatness of the cut. No additional grinding is required afterward, reducing processing costs. Attached Figure Description

[0028] Example:

[0029] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a processing device for metal parts of intelligent elevators, such as... Figure 1As shown, the machine includes a processing table 1. A straight cutting groove 3 is formed on one side of the upper surface of the processing table 1. A fixed bracket 4 is fixedly installed on the upper surface of the processing table 1 near the straight cutting groove 3. A top plate 5 is fixedly installed on the top of the fixed bracket 4. A movable plate 6 is movably installed below the top plate 5. A cylinder 7 is movably installed at each of the four corners of the movable plate 6 via bearing seats. A drilling bit 8 is fixedly installed at the bottom of each cylinder 7. A central shaft 16 is movably installed in the middle of the top plate 5 via bearing seats. A crossbeam 18 is fixedly installed at the bottom of the movable plate 6. A rotating frame 19 is movably installed at both ends of the crossbeam 18. The inner sides of the crossbeam 18 are fixed... A spring plate 20 is installed, and the ends of the spring plates 20 extend into the interior of the corresponding side rotating frame 19. Pressure rollers 21 are fixedly installed on the inner side wall of the rotating frame 19, and the tops of the pressure rollers 21 abut against the lower surface of the corresponding side spring plate 20. A connecting rod 22 is movably installed at the bottom of the rotating frame 19, and the ends of the connecting rods 22 are movably installed on both sides of the top of the positioning pressure block 23. A movable table 25 is movably installed on the bottom of the processing table 1 near the cutting straight groove 3 via two guide rods 24. An installation groove 26 is opened in the middle of the movable table 25, and a cold saw cutting machine 27 is installed inside the installation groove 26 near the cutting straight groove 3. The processing table 1 serves as the installation base for the entire device, providing stable installation support for all components and ensuring that the device does not shake during operation, thus guaranteeing processing accuracy. The cutting groove 3 provides movement space for the cold saw cutting machine 27 during cutting operations, allowing the cold saw cutting machine 27 to move smoothly along the cutting groove 3 and accurately cut the elevator metal parts on the processing table 1, avoiding interference between the saw blade and the processing table 1 during the cutting process. The fixed bracket 4 is used to fix and support the top plate 5, enabling the top plate 5 to be stably installed above the processing table 1, providing an installation carrier for components such as the movable plate 6 and the inner rod 9. The top plate 5 serves as the installation base for the upper structure, providing movable support for the central shaft 16 and the inner rod 9 through the bearing seat, ensuring that the central shaft 16 and the inner rod 9 can rotate flexibly, ensuring the normal operation of the drilling mechanism. The movable plate 6 can be mounted on the top plate 16. The plate 5 moves up and down below, and its bottom fixed crossbeam 18 is used to install the rotating frame 19 and other clamping mechanisms. At the same time, the internal cylinder 7 is used to install the drilling bit 8, realizing the synchronous lifting and lowering of the drilling and clamping mechanisms. The cylinder 7 is movably mounted on the movable plate 6 through the bearing seat and can rotate flexibly, thereby driving the drilling bit 8 at the bottom to rotate, realizing the drilling operation on the elevator metal parts. The drilling bit 8 directly contacts the workpiece to complete the drilling process. The central shaft 16 is movably mounted in the middle of the top plate 5 through the bearing seat. Its top end is connected to the drive gear 14 and its bottom end is connected to the threaded rod 17, which plays the role of transmitting power and driving the threaded rod 17 to rotate synchronously. The crossbeam 18 is fixed at the bottom of the movable plate 6 and is used to install the rotating frame 19 and the spring plate 20, providing installation support for the clamping mechanism and ensuring that the clamping mechanism can rise and fall synchronously with the movable plate 6.The rotating frame 19 is movably mounted at both ends of the cross frame 18 and can rotate around the connection point with the cross frame 18. It drives the positioning block 23 to move up and down via the connecting rod 22, thus clamping and releasing the workpiece. The spring plate 20 is fixed inside both sides of the cross frame 18, with its ends extending into the rotating frame 19. When the rotating frame 19 rotates, the pressure roller 21 bends the spring plate 20. The elastic force generated by the spring plate 20 is transmitted to the positioning block 23 via the connecting rod 22, providing a stable clamping force to the positioning block 23. The pressure roller 21 is fixed to the rotating frame. On the inner wall of the rotating frame 19, its top end abuts against the lower surface of the spring plate 20. When the rotating frame 19 rotates, the pressure roller 21 slides relative to the surface of the spring plate 20, dynamically compensating for the change in elastic force during the bending process of the spring plate 20, so that the clamping force of the positioning pressure block 23 remains constant. The connecting rod 22 is movably connected between the bottom end of the rotating frame 19 and the top end of the positioning pressure block 23, playing a role in force transmission, converting the rotational motion of the rotating frame 19 into the up-and-down linear motion of the positioning pressure block 23, realizing the clamping and loosening of the workpiece; the positioning pressure... Block 23 is used to directly contact the elevator metal parts, pressing the workpiece firmly onto the processing table 1 to prevent displacement during drilling and cutting, ensuring processing accuracy. Guide rod 24 is fixed to the bottom of the processing table 1, used to limit and guide the movable table 25, ensuring it can move smoothly along the guide rod 24 and preventing deviation during movement, thus ensuring cutting accuracy. The movable table 25 is movably mounted on the bottom of the processing table 1 via the guide rod 24. Its internal mounting groove 26 is used to install the cold saw cutter 27, horizontal shaft 29, and other cutting-related components, driving these components to move synchronously to achieve the cutting operation of the workpiece. The mounting groove 26 is located in the middle of the movable table 25, providing installation space for the cold saw cutter 27, horizontal shaft 29, and other components, while also facilitating the coordinated operation of each component. The cold saw cutter 27 is located inside the mounting groove 26 on the side near the cutting groove 3. Its saw blade can rotate at high speed, coordinating with the movement of the movable table 25 to cut the elevator metal parts, and is the core component of the device's cutting function.

[0030] In this embodiment, two positioning guide rails 2 are fixedly installed on the upper surface of the processing table 1. The two positioning guide rails 2 are fixed parallel to each other on the upper surface of the processing table 1 and are used to guide and limit the workpiece of elevator metal parts. The workpiece can be placed between the two positioning guide rails 2 and driven forward smoothly by the feeding device to ensure that the workpiece will not shift to the left or right during the advancement process. This ensures that the workpiece can be accurately moved to the drilling and cutting position, providing a guarantee for the accuracy of subsequent drilling and cutting. At the same time, it is suitable for the continuous advancement of batch workpieces, improving processing efficiency. The setting of the positioning guide rails 2 also makes the positioning of the workpiece more convenient, eliminating the need for an additional positioning mechanism and simplifying the processing flow.

[0031] Furthermore, inner rods 9 are movably installed at the four corners of the top plate 5 via bearing seats. Splines 10 are fixedly installed on both sides of the bottom of the inner rods 9. Keyways 11 are opened on both sides of the inner wall of the cylinder 7. The outer ends of the splines 10 are movably set on the inner wall of the corresponding side keyways 11. The inner rod 9 is movably mounted at the four corners inside the top plate 5 via bearing seats, allowing it to rotate flexibly. Its top end is connected to the driven gear 12, enabling it to rotate synchronously under the drive of the driven gear 12, providing power for the rotation of the cylinder 7 and the drilling bit 8. The spline 10 is fixed on both sides of the bottom of the inner rod 9, and the keyway 11 is opened on both sides of the inner wall of the cylinder 7. The cooperation between the spline 10 and the keyway 11 serves to limit and transmit power, ensuring that the inner rod 9 rotates synchronously with the cylinder 7, and also allowing the cylinder 7 to move up and down relative to the inner rod 9. This ensures that when the movable plate 6 moves the cylinder 7 and the drilling bit 8 up and down, the inner rod 9 can still drive the cylinder 7 to rotate normally, thereby achieving the coordinated operation of the rotating drilling and the up and down feeding action of the drilling bit 8, ensuring the smooth progress of drilling operations. At the same time, the cooperation between the spline 10 and the keyway 11 also makes the installation and disassembly of the cylinder 7 more convenient, facilitating subsequent maintenance and replacement.

[0032] Furthermore, the top of the inner rod 9 extends to the top plate 5 and is fixedly installed with a driven gear 12. A reduction motor 13 is fixedly installed on the top plate 5 via a bracket. A driving gear 14 is fixedly installed on the drive end of the reduction motor 13. The inner end of the driven gear 12 is meshed with the outer diameter of the driving gear 14. The top of the central shaft 16 is fixedly installed at the middle of the bottom end of the driving gear 14. Driven gear 12 is fixed to the top of inner rod 9 and extends above top plate 5. It meshes with drive gear 14 to transmit power from drive gear 14 to inner rod 9, causing inner rod 9 to rotate. The four driven gears 12 correspond to the four inner rods 9 respectively, ensuring that the four inner rods 9 can rotate synchronously, thereby driving the four drilling bits 8 to rotate synchronously and ensuring consistent drilling. Gear motor 13 is fixed above top plate 5 by bracket. As the power source of drilling mechanism, it can provide stable rotational power. At the same time, gear motor 13 can reduce speed and increase torque, ensuring that drilling bits 8 can obtain sufficient rotational torque to meet the drilling requirements of elevator metal parts. It also operates stably and is easy to control. Rotational speed; The drive gear 14 is fixed to the drive end of the geared motor 13 and rotates under the drive of the geared motor 13. Through meshing with the four driven gears 12, it drives the four driven gears 12 to rotate synchronously, realizing synchronous power transmission and ensuring that the rotational speed of the four inner rods 9 is consistent. This ensures that the rotational speed of the four drilling bits 8 is the same, improving drilling accuracy. The top of the central shaft 16 is fixed to the middle of the bottom of the drive gear 14 and can rotate synchronously under the drive of the drive gear 14. It transmits the power of the geared motor 13 to the threaded rod 17 below, realizing the synchronous supply of rotational power and lifting power of the drilling mechanism. This simplifies the power transmission structure and makes the overall structure of the device more compact.

[0033] Furthermore, a threaded sleeve 15 is fixedly installed in the middle of the movable plate 6, and a threaded rod 17 is fixedly installed at the bottom of the central shaft 16, with the outer diameter of the threaded rod 17 threadedly connected to the inside of the threaded sleeve 15. The threaded sleeve 15 is fixed in the middle of the movable plate 6 and moves up and down synchronously with the movable plate 6. It has an internal thread that engages with the external thread of the threaded rod 17 to form a threaded transmission mechanism. The threaded rod 17 is fixed at the bottom of the central shaft 16 and rotates synchronously with the central shaft 16. When the central shaft 16 drives the threaded rod 17 to rotate, the rotational motion is converted into the vertical linear motion of the movable plate 6 through the threaded engagement between the threaded rod 17 and the threaded sleeve 15, realizing the smooth lifting and lowering of the movable plate 6, which in turn drives the drilling bit 8 and the clamping mechanism to lift and lower synchronously. This threaded transmission method is smooth and precise, and can accurately control the lifting height of the movable plate 6, thereby accurately controlling the drilling depth and the clamping degree of the positioning block 23, meeting the high-precision processing requirements of elevator metal parts. At the same time, the threaded transmission has a self-locking function, which can fix the movable plate 6 at any height, preventing the movable plate 6 from falling unexpectedly during processing, and ensuring processing safety and processing accuracy.

[0034] Furthermore, a horizontal shaft 29 is movably mounted in the center of the mounting groove 26, and a transmission gear 30 is fixedly mounted on the outer diameter of the center of the horizontal shaft 29. The horizontal shaft 29 is movably mounted in the center of the mounting groove 26 via a bearing seat, allowing it to rotate flexibly. One end is used to mount the chuck 31, and the middle is used to mount the transmission gear 30, which transmits power from the rotation of the transmission gear 30 to the chuck 31. The transmission gear 30 is fixed on the outer diameter of the center of the horizontal shaft 29 and rotates synchronously with the horizontal shaft 29. Its top end meshes with the rack plate 34. When the movable table 25 moves, the transmission gear 30 meshes with the rack plate 34 fixed at the bottom of the processing table 1, driving the transmission gear 30 to rotate, which in turn drives the horizontal shaft 29 and the chuck 31 to rotate, providing power for the vibration of the cold saw cutting machine 27, realizing the coordinated operation of cutting and vibration, and improving cutting efficiency and cut quality.

[0035] Furthermore, a chuck 31 is fixedly installed on the outer diameter of the horizontal axis 29 near the cold saw cutter 27, and a top frame 32 is fixedly installed at the bottom of the end of the cold saw cutter 27 near the transmission gear 30. Several hemispherical protrusions 33 are fixedly installed on the top of the top frame 32 and the outer diameter of the transmission gear 30. Both ends of the cold saw cutter 27 are connected to the inner wall of the mounting groove 26 by tension springs 28. The chuck 31 is fixed to the side of the horizontal shaft 29 near the cold saw cutting machine 27 and rotates synchronously with the horizontal shaft 29. The hemispherical protrusion 33 on its outer diameter cooperates with the hemispherical protrusion 33 on the top frame 32. When the chuck 31 rotates, the two hemispherical protrusions 33 will continuously misalign and engage, pushing the top frame 32 to move up and down, thereby causing the cold saw cutting machine 27 to vibrate up and down. The top frame 32 is fixed to the bottom of the end of the cold saw cutting machine 27 near the transmission gear 30. It is used to install the hemispherical protrusions 33, transmit the rotational power of the chuck 31, and drive the cold saw cutting machine 27 to vibrate. This causes the cold saw cutting machine 27 to vibrate up and down while rotating and cutting at high speed, improving the cutting effect. The hemispherical protrusions 33 are respectively fixed to the top of the top frame 32 and the outer diameter of the chuck 31. The arc-shaped structure of the cold saw 27 allows for smoother engagement and reduced wear, while also ensuring stable power transmission. This ensures uniform vibration and prevents excessive or insufficient vibration from affecting cutting quality. The tension spring 28 connects the two ends of the cold saw 27 to the inner wall of the mounting groove 26, providing elastic reset. When the hemispherical protrusion 33 on the chuck 31 separates from the hemispherical protrusion 33 on the top frame 32, the tension spring 28 pulls the cold saw 27 back to its original position, allowing it to vibrate continuously up and down. This, combined with the rotation of the chuck 31, achieves high-frequency vibration. The tension spring 28 also buffers the impact force generated by the vibration of the cold saw 27, protecting it and extending its service life.

[0036] Furthermore, a rack plate 34 is fixedly installed on the bottom end of the processing table 1 near the movable table 25, and the bottom end of the rack plate 34 is meshed with the top end of the transmission gear 30. The rack plate 34 is fixed on the bottom end of the processing table 1 near the movable table 25, and its length is adapted to the length of the cutting straight groove 3. It is used to mesh with the transmission gear 30. When the movable table 25 moves along the guide rod 24, the transmission gear 30 will roll on the rack plate 34, and meshing transmission will occur, thereby driving the transmission gear 30 to rotate. Without the need for an additional power source, the rotation of the transmission gear 30, the horizontal shaft 29 and the chuck 31 can be realized, which simplifies the device structure and reduces energy consumption. At the same time, the meshing transmission between the rack plate 34 and the transmission gear 30 is smooth and precise, which can ensure that the rotation speed of the transmission gear 30 matches the moving speed of the movable table 25, so that the vibration frequency of the cold saw cutting machine 27 is coordinated with the cutting speed, further improving the cutting efficiency and cut quality.

[0037] Furthermore, a lead screw 35 is movably installed on the side of the machining table 1 near the movable table 25, and the outer diameter of the middle part of the lead screw 35 is threaded to one side of the movable table 25. A stepper motor 36 is fixedly installed on one side of the machining table 1, and the drive end of the stepper motor 36 is fixedly installed on one end of the lead screw 35. The lead screw 35 is movably mounted on the side of the processing table 1 near the movable table 25. Its middle part is threaded to the movable table 25, and both ends are supported by bearing seats, allowing it to rotate flexibly. Through threaded transmission, it drives the movable table 25 to move smoothly along the guide rod 24. The stepper motor 36 is fixed on one side of the processing table 1, serving as the power source for the movement of the movable table 25. Its drive end is fixedly connected to one end of the lead screw 35, enabling it to drive the lead screw 35 to rotate precisely. The stepper motor 36 features controllable speed and precise positioning, allowing for precise control of the rotation angle of the lead screw 35, and thus precise control of the moving distance and speed of the movable table 25. This ensures that the cold saw cutting machine 27 can accurately cut to the designated position of the workpiece, meeting the cutting accuracy requirements of elevator metal parts. At the same time, the stepper motor 36 operates stably, enabling automated control, adapting to batch processing needs, and improving processing consistency and efficiency.

[0038] Working principle:

[0039] The elevator component workpiece to be processed is placed between two positioning guide rails 2 and advanced forward by the feeding device. When the workpiece moves to below the fixed bracket 4, the reduction motor 13 is started, which drives the drive gear 14 to rotate, thereby rotating the central shaft 16. When the central shaft 16 rotates, it drives the threaded rod 17 to rotate, which, together with the threaded sleeve 15, drives the movable plate 6 to descend. When the movable plate 6 descends, it drives the cross frame 18 to descend, thereby driving the positioning block 23 to descend. When the positioning block 23 contacts the workpiece, the movable plate 6 continues to descend. At this time, the positioning block 23 drives the rotating frame 19 to rotate through the connecting rod 22. The rotating frame 19 bends the spring plate through the pressure roller 21. 20. The bent spring plate 20 generates elastic force that reverses through the connecting rod 22 to exert pressure on the positioning block 23, thereby pressing the workpiece. In addition, the pressure roller 21 slides relative to the surface of the bent spring plate 20, causing the lever arm of the spring plate 20 to change, compensating for the change in elastic force as the degree of bending changes, so that the generated elastic force remains stable. This ensures that the pressing force of the positioning block 23 on the workpiece remains stable, ensuring that the workpiece is not damaged due to excessive pressure while pressing and positioning. As the movable plate 6 continues to descend, it also drives the cylinder 7 and the drill bit 8 to descend. When the drive gear 14 rotates, it drives the driven gears 12 and the inner rod 9 around it to rotate. 9. Through the limiting engagement of spline 10 and keyway 11, all cylinders 7 and drilling bits 8 are driven to rotate at high speed, thereby drilling the workpiece. After drilling is completed, positioning block 23 and drilling bit 8 rise and reset. At this time, the feeding device continues to control the workpiece to move forward. When the workpiece moves to the appropriate position, the movable plate 6 descends to the appropriate height again. At this time, only positioning block 23 presses the workpiece. Then, stepper motor 36 is started. Stepper motor 36 drives lead screw 35 to rotate. Using the limiting action of guide rod 24, it drives movable table 25 and saw blade of cold saw cutting machine 27 to move along the cutting straight groove 3. When cold saw cutting machine 27 is started, saw blade rotates at high speed to cut the workpiece. During the cutting operation, as the movable table 25 moves, it drives the transmission gear 30 to mesh with the rack plate 34, causing the transmission gear 30 to rotate. When the transmission gear 30 rotates, it drives the chuck 31 to rotate. When the chuck 31 rotates, the hemispherical protrusion 33 on the outer diameter of the chuck 31 and the hemispherical protrusion 33 on the top frame 32 will continuously misalign and engage. With the action of the tension spring 28, the cold saw cutting machine 27 will continuously vibrate up and down. Combined with the high-speed rotating saw blade, this not only reduces the cutting pressure and improves the cutting efficiency, but also polishes the workpiece and reduces the burrs generated during cutting. Finally, the positioning block 23 rises and resets, and the feeding device controls the workpiece to move forward again. This cycle repeats continuously.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
