Description

Technical Field

[0001] This invention relates to the field of thread processing equipment technology, and in particular to a thread processing equipment based on screw manufacturing. Background Technology

[0002] In modern manufacturing, screws are one of the indispensable fasteners, used to secure two or more objects together and ensure their stability and safety during use. Thread processing equipment is one of the key pieces of equipment in screw manufacturing, which uses precise control to process threads that meet standard or special requirements to satisfy different application needs.

[0003] The screw threading device, with announcement number CN119035675A, solves the problems of traditional screw threading devices, which cannot perform threading on different types of screws without disassembling the device, have a limited range of screw processing capabilities, reduce the flexibility of the device during use, and have poor screw stability during threading. However, similar structures still have many defects in practical use. For example, existing threading devices mostly adopt a single-station, one-by-one processing mode, that is, after completing the threading of each screw, the machine must be stopped for loading and unloading operations before clamping and processing the next screw. This intermittent operation mode of "processing-stopping-unloading-reprocessing" results in extremely low equipment utilization, long single-piece processing cycle, and severely limited overall capacity, making it difficult to meet the capacity requirements of mass screw manufacturing.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

The two ends of the guide wheel are mounted inside the movable cover through shafts, and the outer side of the guide wheel is movably connected to the inside of the drive slot plate.

[0010] Preferably, the reciprocating switching mechanism consists of a slide rail frame, a reciprocating screw, and a reciprocating sleeve. The reciprocating sleeve moves inside the slide rail frame, and the reciprocating screw rotates to be installed inside the slide rail frame, with the reciprocating screw passing through the reciprocating sleeve.

[0011] Preferably, the intermittent stepping transmission mechanism consists of a stroke adjustment mechanism, a traction shaft, and an intermittent transmission assembly. One end of the traction shaft is connected to the front shaft of the stroke adjustment mechanism, and the other end of the traction shaft is connected to the shaft of the intermittent transmission assembly. The intermittent transmission assembly is connected to a reciprocating screw drive.

[0012] Preferably, the stroke adjustment mechanism consists of a rotary disk, an adjusting screw, an adjusting sleeve, and a servo motor. The back of the rotary disk has a spline groove, which is splined into the spline socket of the driven gear. The adjusting screw is rotated inside the rotary disk. The servo motor is fixedly mounted on the outside of the rotary disk, and its output end is fixedly connected to one end of the adjusting screw. The adjusting sleeve is fitted onto the outside of the adjusting screw, and a connecting shaft is rotatably mounted on the front of the adjusting sleeve.

[0015] The beneficial effects of this invention are: The technical solution of this invention uses a gear transmission mechanism to simultaneously drive an eccentric reciprocating drive mechanism and an intermittent stepping transmission mechanism, enabling the horizontal reciprocating cutting motion of the thread cutting mechanism and the intermittent equidistant displacement of the reciprocating shifting mechanism to achieve motion coordination under the same power source. This reduces costs, minimizes failure points, and ensures precise timing coordination between each action. Specifically, the intermittent stepping transmission mechanism achieves intermittent transmission through the engagement of a ratchet and a pawl. The gear transmission mechanism drives the stroke adjustment mechanism to rotate, and the rotating stroke adjustment mechanism drives the pawl to periodically lock and disengage from the ratchet. During the locking phase, the ratchet is driven to perform intermittent... The intermittently rotating ratchet drives the reciprocating screw to rotate, causing the reciprocating sleeve to move intermittently and equidistantly within the slide rail frame. This, in turn, drives the multi-station clamping mechanism to move intermittently and equidistantly, switching the screw processing station. After the thread cutting mechanism finishes processing the screw at the current station, the reciprocating switching mechanism drives the screw at the next station to the processing position and completes the unloading of the previous finished screw. This achieves parallel operation of processing and unloading. The device can complete continuous processing and unloading of screws without stopping the machine. Compared with the traditional single-station processing mode, the production capacity is increased several times, and the processing cycle time of a single piece is significantly shortened.

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 11 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] A thread processing device based on screw manufacturing includes a base 1, a reciprocating drive mechanism 3, a thread cutting mechanism 4, and an intermittent stepping transmission mechanism 8. A mounting box 101 is fixedly mounted on the top of the base 1, and a guide rail 102 is fixedly mounted on the top of the mounting box 101. A door is hinged to one side of the mounting box 101, allowing for easy inspection of the internal structure. A controller is placed inside the mounting box 101, and is electrically connected to the electrical equipment within the device via wires for easy control of the electrical equipment's operation. The guide rail 102 provides guidance for the movement of the thread cutting mechanism 4, ensuring stable movement of the thread cutting mechanism 4. A vertical adjustment mechanism 5 is fixedly installed on the side of the mounting box 101. A reciprocating shifting mechanism 6 is fixedly installed on the front of the vertical adjustment mechanism 5. A multi-station clamping mechanism 7 is fixedly installed on the front of the reciprocating shifting mechanism 6. The vertical adjustment mechanism 5 consists of a guide rail, an adjusting threaded rod, a servo motor, and a movable thread sleeve seat. The servo motor is embedded inside the base 1. The bottom end of the adjusting threaded rod is fixedly connected to the output end of the servo motor. The movable thread sleeve seat is sleeved on the outside of the adjusting threaded rod. The reciprocating shifting mechanism 6 is fixedly installed on the front of the thread sleeve seat by bolts. The movable thread sleeve seat is movably installed inside the guide rail. The guide rail limits the movement direction of the movable thread sleeve seat to ensure stable movement. The servo motor drives the adjusting threaded rod to rotate. The movable thread sleeve seat converts the rotational force of the adjusting threaded rod into a linear force, which drives the reciprocating shifting mechanism 6 to move vertically. This, in turn, drives the multi-station clamping mechanism 7 to move vertically, adjusting the machining position of the screw held by the multi-station clamping mechanism 7 and the thread cutting tool 405. The reciprocating shifting mechanism 6 consists of a slide rail frame 601, a reciprocating screw 602, and a reciprocating screw sleeve 603. The reciprocating screw sleeve 603 moves inside the slide rail frame 601, and the reciprocating screw 602 rotates to be installed inside the slide rail frame 601, and the reciprocating screw 602 passes through the reciprocating screw sleeve 603. The multi-station clamping mechanism 7 is fixedly installed on the front of the reciprocating screw sleeve 603 by bolts, and the reciprocating screw sleeve 603 can convert the rotational force of the reciprocating screw 602 into reciprocating moving force; The intermittent stepping transmission mechanism 8 transmits the driving force of the gear transmission mechanism 2 to the reciprocating screw 602, which drives the reciprocating screw sleeve 603 to move intermittently inside the slide rail frame 601, thereby driving the multi-station clamping mechanism 7 on the front of the reciprocating screw sleeve 603 to move intermittently, so as to realize the intermittent switching of the position of the screw clamped by the multi-station clamping mechanism 7. The gear transmission mechanism 2 is fixedly installed inside the mounting box 101. The gear transmission mechanism 2 consists of a drive motor 201, a drive gear 202 and a driven gear 203. One side of the drive gear 202 is fixedly connected to the output end of the drive motor 201 through a shaft. The driven gear 203 is meshed with one side of the drive gear 202, and a spline socket is provided inside the driven gear 203. When the drive motor 201 is powered on, it drives the drive gear 202 to rotate. The rotating drive gear 202 drives the meshing driven gear 203 to rotate. The rotating driven gear 203 drives the reciprocating drive mechanism 3 and the intermittent stepping transmission mechanism 8 to run through the internal spline socket. The reciprocating drive mechanism 3 is mounted inside the mounting box 101 via a shaft, and the top of the reciprocating drive mechanism 3 extends into the thread cutting mechanism 4. The reciprocating drive mechanism 3 is connected to the gear transmission mechanism 2. The reciprocating drive mechanism 3 consists of a drive slot plate 301, a sliding plate 302, a stroke adjustment component 303, and a guide wheel 304. The drive slot plate 301 is rotatably mounted inside the mounting box 101, and the sliding plate 302 is movably mounted on the drive slot plate 301. The sliding plate 302 is connected to the stroke adjustment component 303 in a transmission connection. A spline seat 305 is fixedly mounted on the back of the stroke adjustment component 303, and the spline seat 305 is spline-engaged with the driven gear 203 through a spline socket. The two ends of the guide wheel 304 are mounted inside the movable cover 402 through shafts, and the outer side of the guide wheel 304 is movably connected to the inside of the drive slot plate 301. It should be noted that the stroke adjustment component 303 is splinedly connected to the spline socket inside the driven gear 203 via the spline seat 305. The rotating driven gear 203 drives the stroke adjustment component 303 to rotate via the spline seat 305 connected by the spline. The rotating stroke adjustment component 303 drives the sliding plate 302 to rotate eccentrically, which in turn drives the drive slot plate 301 to reciprocate around the shaft at the bottom. The reciprocating drive slot plate 301 drives the thread cutting mechanism 4 to reciprocate on the guide slide rail 102 via the guide wheel 304. The thread cutting mechanism 4 reciprocates relative to the screw held by the multi-station clamping mechanism 7. The stroke adjustment assembly 303 consists of a slide frame, an adjusting screw, and an adjusting sleeve. The adjusting screw is rotatably installed inside the slide frame, and the adjusting sleeve is threaded onto the outside of the adjusting screw. The front of the adjusting sleeve is fixedly connected to the back of the sliding plate 302. It should be noted that a position sensor is embedded inside the slide rail to detect the position of the adjusting sleeve. A knob extending to the outside of the slide rail is fixedly installed at one end of the adjusting screw. By holding the knob, the adjusting screw is rotated, which drives the adjusting sleeve to move inside the slide rail. The position sensor monitors the position of the adjusting sleeve in real time and transmits the detection electrical signal to the controller. The controller provides timely feedback on the position information of the adjusting sleeve, which allows the staff to accurately adjust the position of the adjusting sleeve. Since the sliding plate 302 is fixedly installed on the front of the adjusting sleeve, the rotation range of the sliding plate 302 is adjusted by adjusting the position of the adjusting sleeve, thereby adjusting the amplitude and stroke of the reciprocating swing of the drive slot plate 301. This allows for precise control of the reciprocating stroke of the thread cutting mechanism 4 according to the length of the screw. The intermittent stepping transmission mechanism 8 is rotatably mounted on the back of the mounting box 101. The intermittent stepping transmission mechanism 8 is connected to the gear transmission mechanism 2. The intermittent stepping transmission mechanism 8 consists of a stroke adjustment mechanism 801, a traction shaft 802, and an intermittent transmission assembly 803. One end of the traction shaft 802 is connected to the front shaft of the stroke adjustment mechanism 801, and the other end of the traction shaft 802 is connected to the shaft of the intermittent transmission assembly 803. The intermittent transmission assembly 803 is connected to the reciprocating screw 602. The stroke adjustment mechanism 801 consists of a rotating disk 8011, an adjusting screw 8012, an adjusting sleeve 8013, and a servo motor 8014. The rotating disk 8011 has a spline groove 8015 on its back side. The rotating disk 8011 is splined to the spline socket inside the driven gear 203 through the spline groove 8015. The rotation of the adjusting screw 8012 is installed inside the rotating disk 8011. The servo motor 8014 is fixedly installed on the outside of the rotating disk 8011, and the output end of the servo motor 8014 is fixedly connected to one end of the adjusting screw 8012. The adjusting sleeve 8013 is sleeved on the outside of the adjusting screw 8012, and a connecting shaft is rotatably installed on the front of the adjusting sleeve 8013. One end of the traction shaft 802 is movably connected to the connecting shaft on the front of the adjusting sleeve 8013. It should be noted that when the servo motor 8014 is powered on, it drives the adjusting screw 8012 to rotate. The rotating adjusting screw 8012 drives the adjusting sleeve 8013 to move inside the rotating disk 8011, thereby adjusting the eccentric position of the adjusting sleeve 8013. By adjusting the eccentric position of the adjusting sleeve 8013 inside the rotating disk 8011, the intermittent transmission stroke of the intermittent transmission component 803 is adjusted, and the intermittent driving distance of the reciprocating shifting mechanism 6 to the multi-station clamping mechanism 7 is adjusted, which facilitates flexible adjustment according to the number of screws clamped by the multi-station clamping mechanism 7. The intermittent transmission assembly 803 consists of a ratchet 8031, a shaft bracket 8032, and a pawl 8033. The back of the ratchet 8031 ​​is fixedly connected to one end of the reciprocating screw 602. The shaft bracket 8032 is rotatably mounted on the front of the ratchet 8031, and the pawl 8033 is rotatably mounted on the back of the shaft bracket 8032. The pawl 8033 is dynamically connected to the ratchet 8031. It should be noted that the rotating stroke adjustment mechanism 801 uses eccentric rotational force to drive the traction shaft 802 to rotate the shaft bracket 8032. The rotating shaft bracket 8032 drives the pawl 8033 to rotate and move away from the ratchet 8031, disengaging the pawl 8033 from the ratchet 8031. The continuing to rotate stroke adjustment mechanism 801 drives the pawl 8033 to rotate and move closer to the ratchet 8031, driving the ratchet 8031 ​​to rotate intermittently. The intermittently rotating ratchet 8031 ​​drives the reciprocating screw 602 to rotate. Working principle: According to processing needs, a certain number of screws are clamped by the multi-station clamping mechanism 7. The driving stroke of the stroke adjustment mechanism 801 is adjusted according to the number of screws clamped by the multi-station clamping mechanism 7. Specifically, the adjusting screw 8012 is rotated by the servo motor 8014, and the adjusting sleeve 8013 converts the rotational force of the adjusting screw 8012 into linear movement force. The traction stroke of the traction shaft 802 connected to the connecting shaft is adjusted by adjusting the eccentric position of the adjusting sleeve 8013, thereby adjusting the intermittent transmission stroke of the intermittent transmission component 803. The vertical position of the reciprocating shifting mechanism 6 is adjusted by the vertical adjustment mechanism 5 according to the screw specifications, thereby driving the multi-station clamping mechanism 7 to move vertically and adjusting the machining position of the screw clamped by the multi-station clamping mechanism 7 and the thread cutting tool 405. And the thread cutting mechanism 4 moves according to the screw specifications or the screw thread processing length; specifically, the adjustment screw is rotated by the knob in the hand stroke adjustment component 303, which drives the adjustment screw sleeve to move inside the slide frame, and the position of the adjustment screw sleeve is monitored in real time by the position sensor, and the detection electrical signal is transmitted to the controller. The controller provides timely feedback on the position information of the adjustment screw sleeve, which makes it convenient for the staff to accurately adjust the position of the adjustment screw sleeve. The amplitude of the reciprocating swing of the sliding plate 302 and the drive slot plate 301 is adjusted by adjusting the eccentric position of the adjustment screw sleeve. The eccentric reciprocating drive mechanism 3 is driven by the gear transmission mechanism 2 to drive the thread cutting mechanism 4 to move horizontally and reciprocally. At the same time, the gear transmission mechanism 2 drives the reciprocating shifting mechanism 6 to run intermittently through the intermittent stepping transmission mechanism 8. The controller controls the drive motor 201 to be powered on and run, which drives the drive gear 202 to rotate, which in turn drives the meshing driven gear 203 to rotate. The rotating driven gear 203 drives the spline-connected stroke adjustment component 303 and stroke adjustment mechanism 801 to rotate through the internal spline socket. The rotating stroke adjustment component 303 drives the sliding plate 302 to rotate eccentrically, which in turn drives the drive slot plate 301 to reciprocate around the shaft at the bottom. The reciprocating drive slot plate 301 drives the thread cutting mechanism 4 to reciprocate on the guide slide rail 102 through the guide wheel 304. The thread cutting mechanism 4 reciprocates relative to the screw held by the multi-station clamping mechanism 7. The height of the reciprocating stroke of the thread cutting mechanism 4 is consistent each time, ensuring uniform thread processing depth. Simultaneously, the rotating stroke adjustment mechanism 801 is transmitted to the intermittent transmission assembly 803 via the traction shaft 802. The intermittent transmission assembly 803 drives the reciprocating shifting mechanism 6 to intermittently move. The intermittently moving reciprocating shifting mechanism 6 drives the multi-station clamping mechanism 7 to intermittently move at equal intervals, switching the screw positions clamped by the multi-station clamping mechanism 7. Specifically, the rotating stroke adjustment mechanism 801 uses eccentric rotational force to traction the shaft 802 to move reciprocally. The reciprocating traction shaft 802 tractions the shaft frame 8032 to rotate, and the rotating shaft frame 8032 drives the pawl 8033 to rotate. Move away from ratchet 8031 ​​to disengage pawl 8033 from ratchet 8031; while the continuing to rotate stroke adjustment mechanism 801 drives pawl 8033 to rotate and move closer to ratchet 8031, locking with ratchet 8031. During the rotation and movement of pawl 8033, ratchet 8031 ​​is driven to rotate intermittently. The intermittently rotating ratchet 8031 ​​drives reciprocating screw 602 to rotate, which in turn drives reciprocating sleeve 603 to move intermittently back and forth inside slide rail frame 601, thereby driving the multi-station clamping mechanism 7 on the front of reciprocating sleeve 603 to move intermittently back and forth. The thread cutting mechanism 4 sequentially processes the screws held by the multi-station clamping mechanism 7. After processing, the corresponding rotating chuck 704 and the contact clamp 705 are released from clamping the screws, allowing the screws to be unloaded. An external screw loading mechanism places the screws to be processed between the rotating chuck 704 and the contact clamp 705, which then clamp and lock them in place. When the multi-station clamping mechanism 7 moves in the reverse direction, the additional screws are brought under the thread cutting tool 405 for thread processing. This allows the device to perform screw unloading and thread processing simultaneously without stopping the machine, achieving a continuous production line operation of "processing-changing-unloading". Compared with single-station processing, the production capacity is increased several times, and the processing cycle time of a single piece is significantly shortened.

[0020] like Figure 5As shown, the thread cutting mechanism 4 is movably mounted on the top of the guide slide rail 102. The thread cutting mechanism 4 consists of a slider 401, a movable cover 402, a mounting plate 403, a tool holder 404, and a thread cutting tool 405. The slider 401 is fixedly mounted on the bottom of the movable cover 402 and movably mounted inside the guide slide rail 102. The mounting plate 403 is fixedly mounted on the side of the movable cover 402. The tool holder 404 is fixedly mounted on the front of the mounting plate 403. The thread cutting tool 405 is locked inside the tool holder 404. It should be noted that the movable cover 402 slides on the guide rail 102 via the slider 401, allowing the movable cover 402 to move precisely in a straight line along the guide rail 102, thereby ensuring the accurate movement trajectory of the thread cutting tool 405 during thread cutting. The mounting plate 403 is fixedly installed on the side of the movable cover 402, providing a mounting position for the tool holder 404. The tool holder 404 is fixedly installed on the front of the mounting plate 403 for mounting the thread cutting tool 405. The tool holder 404 locks the thread cutting tool 405, ensuring the stability of the thread cutting tool 405 during thread processing and facilitating the disassembly and assembly of the thread cutting tool 405 for further processing, thus ensuring the accuracy of thread processing.

[0021] like Figure 11 As shown, the multi-station clamping mechanism 7 consists of a movable seat 701, a bearing seat 702, a worm gear drive assembly 703, a rotating chuck 704, and abutting clamps 705. The movable seat 701 has a slag collection port inside, and a collection box 706 is installed inside the movable seat 701 through a sliding groove. The bearing seat 702 is fixedly installed on one side of the top of the movable seat 701. The worm gear drive assembly 703 is installed on one side of the bearing seat 702 through a shaft seat. Multiple rotating chucks 704 are equidistantly rotatably installed on the other side of the bearing seat 702, and the worm gear drive assembly 703 is connected to the multiple rotating chucks 704 in a transmission connection. Multiple abutting clamps 705 are fixedly installed on the other side of the top of the movable seat 701 through a bracket, and the multiple abutting clamps 705 correspond one-to-one with the multiple rotating chucks 704 along the axis. It should be noted that multiple rotating chucks 704 are equidistantly mounted on the other side of the bearing housing 702 and are connected to the worm gear drive assembly 703. The worm gear drive assembly 703 drives the multiple rotating chucks 704 to rotate synchronously. The rotating chucks 704 clamp one end of the screw, and the contact clamps 705 ensure that the other end of the screw is clamped when the rotating chucks 704 rotates horizontally, effectively preventing radial movement of the workpiece due to rotation, further improving machining accuracy and equipment reliability. During unloading, the corresponding rotating chucks 704 and contact clamps 705 are controlled to release the screw from the clamps, achieving complete unloading. The screws to be threaded are unloaded and placed between the rotating chuck 704 and the contact clamp 705 by an external screw loading mechanism. The rotating chuck 704 and the contact clamp 705 clamp and lock the screws. When the multi-station clamping mechanism 7 moves in the reverse direction, the additional screws are brought under the thread cutting tool 405 for threading. The slag collection port inside the moving seat 701 and the collection box 706 installed with it through the slide groove effectively collect the waste chips or other workpiece debris generated during the processing, avoiding the pollution or impact of waste chips on the processing environment and equipment, and maintaining the cleanliness of the working environment.
