Description

Technical Field

[0001] This invention relates to the field of lead screw thread polishing technology, specifically a lead screw thread surface polishing machine. Background Technology

[0002] A screw thread surface polishing machine is a device specifically designed for polishing screw threads, improving the surface finish and machining accuracy of the screw threads. Currently, screw thread surface polishing machines on the market are mainly divided into three types: fluid polishing machines, polishing wheel polishing machines, and abrasive belt polishing machines.

[0003] Existing ball screw thread surface polishing machines mainly suffer from the following technical defects: Of the three existing polishing machines used for ball screw thread surface polishing, the fluid polishing machine provides sufficient contact area for the ball screw thread, but its polishing force is relatively insufficient. The polishing wheel polishing machine and the abrasive belt polishing machine both suffer from insufficient contact area with the ball screw thread, resulting in poor contact between their respective polishing media and the ball screw thread. Therefore, compared to these three types of polishing machines, a polishing machine using abrasive wire surface polishing has been further developed for ball screw thread surface polishing. While traditional abrasive wire polishing increases the contact area and polishing force of the ball screw thread surface, there is still an area where the abrasive wire does not contact the ball screw thread surface, resulting in low polishing efficiency and low abrasive utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a ball screw thread surface polishing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ball screw thread surface polishing machine, comprising: a housing, a clamping mechanism fixedly installed on the inner side of the housing, an adjusting mechanism fixedly installed on the inner side of the housing and on the rear side of the clamping mechanism, a polishing mechanism fixedly connected to the upper side of the adjusting mechanism, an abrasive wire connected to the upper drive of the polishing mechanism, a transmission group and a wire rotation mechanism fixedly connected to the inner side of the polishing mechanism, the wire rotation mechanism being evenly distributed at the four corners of the abrasive wire, the wire rotation mechanism clamping the abrasive wire and driving the abrasive wire to rotate under the drive of the transmission group; The wire rotation mechanism includes wire rotation components, which are distributed on the outer sides of the four corners of the abrasive wire; The wire rotating assembly includes a first semi-circular shell, a second semi-circular shell, and a wire clamping component. The first and second semi-circular shells are detachably and fixedly connected. The first and second semi-circular shells are arranged in two sets about their center to form a ring. The wire clamping component is fixedly connected to the inner side of the ring. The wire clamping component includes a wire clamping wheel. The outer circumference of the wire clamping wheel is provided with evenly distributed concave and convex tooth grooves for clamping the abrasive wire.

[0006] While the first and second semicircular shells rotate, the concave and convex teeth on the clamping wheel clamp the abrasive wire, and the wire rotation mechanism is distributed at the four corners of the abrasive wire, thereby driving the abrasive wire to rotate and flip, thus achieving the purpose of abrasive wire contacting the screw thread surface 360 ​​degrees for polishing, which greatly increases the contact area between the abrasive wire and the screw thread surface. Furthermore, the clamping mechanism includes a base plate, a tailstock assembly, and a machine tool spindle. The base plate is fixed at the middle of the inner side of the machine housing, and the tailstock assembly and the machine tool spindle are fixedly connected to the upper side of the base plate. The tailstock assembly includes a guide rail, a tailstock platform, and a tailstock. The guide rail is fixedly connected to the upper side of the base plate, and the tailstock platform is slidably connected to the upper side of the guide rail. The tailstock platform is fixedly connected to the side of the tailstock platform near the machine tool spindle. The machine tool spindle includes a motor, a pulley, a support platform, a fixed platform, and a pneumatic chuck. The support platform is fixedly connected to the upper side of the base plate, and the motor and the fixed platform are fixedly connected to the upper side of the support platform. A pulley is fixedly connected to the output end of the motor. The pneumatic chuck is rotatably connected to the inner side of the fixed platform. The pulley is fixedly connected to the side of the pneumatic chuck away from the tailstock. A transmission belt drives the pulley and the pulley. The pneumatic chuck and the tailstock are on the same axis. A spindle housing is fixedly installed on the upper side of the support platform.

[0007] The lead screw to be polished is placed between the tailstock and the pneumatic chuck, with one end of the lead screw placed inside the pneumatic chuck. Compressed gas is then supplied to the pneumatic chuck through an external air supply device, causing the pneumatic chuck to clamp the lead screw and push the tailstock to slide on the guide rail. Then, the other end of the lead screw contacts the tailstock, and the tailstock abuts against the lead screw. Since a limit device is installed on the tailstock, when the tailstock abuts against the lead screw, the limit device is controlled to fix the tailstock. At this point, the lead screw to be polished is placed. Furthermore, the control mechanism includes a profile module and an inclined platform. The profile module is fixedly connected to the rear side of the clamping mechanism, and the inclined platform is fixedly connected to the upper side of the profile module. The profile module includes a second base plate, a linear motor, a drag chain, and a sliding block. The second base plate is fixedly connected to the rear side of the first base plate, the linear motor is fixedly connected to the upper side of the second base plate, the sliding block is slidably connected to the upper side of the linear motor, the drag chain is fixedly connected to one side of the sliding block, and the end of the drag chain away from the sliding block is fixedly connected to the second base plate. While the abrasive wire polishes the screw thread, the linear motor is started. The linear motor drives the sliding block to slide back and forth with the assistance of the drag chain, which in turn drives the abrasive wire to polish the screw thread back and forth. The tilting platform includes a second motor, a tilting fixed platform, and a tilting moving platform. The tilting fixed platform is fixedly connected to the upper side of the sliding block. The second motor is fixedly connected to one side of the tilting fixed platform. A track is fixedly connected to the inner side of the second motor. A threaded rod is fixedly connected to the output end of the second motor. The threaded rod is located inside the track, and one end of the threaded rod is rotatably connected to the inner wall of the track. A slider is slidably connected to the upper side of the track and inside the tilting fixed platform. A tilting moving platform is slidably connected to the upper side of the tilting fixed platform. A cylindrical block is provided on the tilting moving platform. An arc-shaped groove corresponding to the cylindrical block is opened on the tilting fixed platform. Fixed shafts are fixedly connected to both the slider and the tilting moving platform. A push-pull rod is rotatably connected between the two fixed shafts. An angle scale is provided on one side of the tilting moving platform.

[0008] Furthermore, the polishing mechanism includes a base plate three, adjustable support wheels, a moving group, a guide group, and a drive group. The base plate three is fixedly connected to the upper side of the tilting moving table. The adjustable support wheels, the moving group, the guide group, and the drive group are sequentially fixedly connected to the upper side of the base plate three from the clamping mechanism toward the control mechanism. A gap is provided between the adjustable support wheels and the moving group for placing the lead screw to be polished.

[0009] The adjustable support wheel is equipped with an electric push rod. The electric push rod pushes the adjustable support wheel, and the support wheel on it contacts the lead screw to provide support for the lead screw. The moving assembly gradually brings the abrasive wire closer to the lead screw, stopping when the abrasive wire has wrapped one-third of the thread of the lead screw. Furthermore, the guide assembly includes a fixed vertical plate, a fixed horizontal plate, and a fixed frame. A fixed vertical plate is fixedly connected to the upper side of the base plate three. Two sets of fixed horizontal plates are fixedly connected to one side of the fixed vertical plate. The two sets of fixed horizontal plates are distributed at the upper and lower ends of the fixed vertical plate. A fixed frame is fixedly connected to the outer side of the upper fixed horizontal plate. Evenly distributed guide wheels are rotatably connected to the fixed horizontal plate, the fixed frame, and the moving assembly.

[0010] Furthermore, the drive assembly includes a motor three, gear one, gear two, a drive wheel, a square rotating shaft, a moving platform, a drive screw, and a guide rail two. The output end of the motor three is fixedly connected to the square rotating shaft. Gear one is fixedly connected to the outer side of the square rotating shaft. Gear two meshes with the lower side of gear one. The drive wheel is slidably connected to the outer side of the square rotating shaft. The moving platform is rotatably connected to the outer side of the drive wheel. The drive wheel has a square hole corresponding to the square rotating shaft. The moving platform has a round hole with a diameter larger than the outer dimension of the square rotating shaft. The upper side of the base plate three is fixedly connected to the guide rail two. The moving platform slides on the guide rail two. The inner side of gear two is fixedly connected to the drive screw. The drive screw and the moving platform are threaded together. The upper side of the base plate three is fixedly connected to two outer plates. The two outer plates enclose the guide assembly and the drive assembly. The motor three is fixedly connected to one of the outer plates. The drive screw is rotatably connected to the inner side of one of the outer plates. The drive assembly, the moving assembly, and the fixed frame are all equipped with collection trays. The collection trays collect the metal powder.

[0011] Start motor three, which drives the square shaft and gear one to rotate. Since the square shaft is square and the drive wheel has a square hole corresponding to the square shaft, the square shaft rotates while driving the drive wheel rotates synchronously, which in turn drives the outer frosting wire to rotate in a ring. This allows the frosting wire to polish the screw thread. Gear one meshes and drives gear two to rotate, which in turn drives the drive screw fixedly connected to it to rotate synchronously. This causes the drive screw to drive the moving table to slide along guide rail two, which in turn drives the drive wheel to rotate while sliding along guide rail two. Intermittently control motor three to rotate in both directions, so that the drive wheel can rotate while sliding back and forth along guide rail two. This allows the drive wheel to have a certain degree of lateral contact with the frosting wire, and the lateral contact force cleans the metal powder on it, preventing the frosting wire from slipping. Furthermore, the transmission assembly includes a motor, a worm, a gear, a worm wheel, a gear, and a transmission belt. Four sets of worms are rotatably connected to the inner side of one of the outer plates. A motor is fixedly connected to the inner side of one of the outer plates. The output end of the motor is fixedly connected to one set of worms. Gears are fixedly connected to the outer sides of two sets of worms. Gears are meshed with gears on the outer sides of gears. One end of each of the other two sets of worms and one end of each of the two sets of gears are fixedly connected to pulleys. Transmission belts are drivingly connected to the outer sides of the four sets of pulleys. The pulleys on the four gears are rotatably connected to one of the outer plates. A worm wheel meshes with the outer side of each worm.

[0012] Furthermore, the wire rotation mechanism includes bearing seats, and the four sets of wire rotation assemblies are rotatably connected to the outer side of the bearing seats. The four sets of bearing seats are fixedly connected to two outer side plates respectively. While the back-and-forth grinding and polishing is being carried out, motor four is started. Motor four drives a set of worm gears to rotate. Gear three on the set of worm gears meshes with gear four and drives gear four to rotate. Pulley two on gear four drives the other pulley two to rotate synchronously through the transmission belt. This makes the upper two sets of worm gears rotate in the opposite direction to the lower two sets of worm gears. Through the meshing of the worm gears and worm wheels, the upper two sets of wire rotating assemblies rotate in the opposite direction to the lower two sets of wire rotating assemblies. The bearing housing includes a bearing housing body and a bearing. The bearing is fixedly connected to the outer side of the semi-circular shell II. The bearing housing body is fixedly connected to the outer side of the bearing. The four sets of bearing housing bodies are respectively fixedly connected to two outer side plates.

[0013] Furthermore, the wire clamping component includes a moving frame, a connecting rotating block, a moving block, a fixed rod, a second track plate, and a moving rod. Four sets of second track plates are fixedly connected to the inner side of the first semi-circular shell. A moving block is slidably connected to the inner side of the second track plate. A fixed rod is fixedly connected to one end of the moving block, and a moving rod is rotatably connected to the other end of the moving block. The fixed rod is rotatably connected to the wire clamping wheel. A rectangular groove corresponding to the moving block is opened on the second track plate. A connecting rotating block is rotatably connected to the other end of the moving rod. A moving frame is fixedly connected to the side of the connecting rotating block away from the moving rod. A threaded operating rod is threadedly connected to the inner side of the moving frame. A rectangular plate is rotatably connected to the outer side of the threaded operating rod. The rectangular plate is fixedly connected to the inner side of the second semi-circular shell.

[0014] The abrasive wire is sleeved on the outside of the guide wheels and drive wheels, and passes through the vibrating wheel and the clamping wheel. Then, because the moving group is equipped with an electric push rod, the electric push rod pushes the guide wheel on it, thereby tightening the abrasive wire. At the same time, the second motor is started, and the second motor drives the threaded rod to rotate, thereby driving the slider to slide on the track. Then, under the action of the push-pull rod, the tilting moving table slides along the tilting fixed table. According to the helix angle of the thread of the screw, since the tilting moving table is equipped with an angle scale, the tilting angle of the tilting moving table is made to match the helix angle of the thread of the screw. By manually cranking the threaded operating rods at various locations, the threaded operating rods drive the moving frame to move along the threaded operating rods, so that the moving frame, through the moving rods, drives the moving block and the fixed rod along the track plate two to drive the clamping wheel to move towards the abrasive wire until the concave and convex grooves on the clamping wheel clamp the abrasive wire. Furthermore, two sets of vibrating elements are fixedly connected to the inner side of the semi-circular shell. The two sets of vibrating elements are staggered about the abrasive wire. Each vibrating element includes an electromagnetic vibrator, a connecting bracket, and a vibrating wheel. An electromagnetic vibrator is fixedly connected to the inner side of the semi-circular shell. The other end of the electromagnetic vibrator is fixedly connected to the connecting bracket. A vibrating wheel is rotatably connected to the inner side of the connecting bracket. The vibrating wheel is in close contact with the abrasive wire.

[0015] While the abrasive wire is rotating in a ring and rotating on its own axis, the electromagnetic vibrator is activated. The electromagnetic vibrator drives the vibrating wheel to vibrate at high frequency through the connecting bracket. Since the two sets of vibrating components are staggered about the abrasive wire, the abrasive wire is vibrated at high frequency, which expands the lateral movement amplitude of the abrasive wire and makes the abrasive wire in full contact with the edge and center of the screw thread surface.

[0016] Compared with the prior art, the present invention provides a ball screw thread surface polishing machine, which has the following beneficial effects: 1. This screw thread surface polishing machine, through the coordinated action of the clamping mechanism, the control mechanism, the polishing mechanism, the guide wheel and the collecting plate, can automatically polish the screw thread surface with abrasive wire, replacing the existing three types of polishing methods: fluid polishing machine, polishing wheel polishing machine and abrasive belt polishing machine. It solves the problems of insufficient contact area or insufficient polishing force of existing polishing machines, which result in poor contact between their respective polishing media and screw threads.

[0017] 2. This screw thread surface polishing machine, through the coordinated action of the transmission group and the screw rotation mechanism, achieves the goal of the abrasive wire rotating in a ring while simultaneously rotating on its own axis. This allows the abrasive wire to contact the screw thread surface 360 ​​degrees for polishing, significantly increasing the contact area between the abrasive wire and the screw thread surface. This ensures that the abrasive wire is in contact with the screw thread surface from all directions, greatly improving the utilization rate of the abrasive wire, saving abrasive, and solving the problem that existing abrasive wires still have areas that do not contact the screw thread surface, resulting in low polishing efficiency and low abrasive utilization.

[0018] 3. This screw thread surface polishing machine uses vibrating components that are staggered and distributed on the outside of the abrasive wire to make close contact with it. This causes the electromagnetic vibrator to drive the vibrating wheel to vibrate at high frequency, thereby increasing the lateral movement range of the abrasive wire. This ensures that the abrasive wire makes full contact with the edge and center of the screw thread surface, preventing dead corners in the abrasive wire polishing the screw thread surface and improving the overall polishing quality.

A collection tray 7 is provided at each of the drive group 45, the moving group 43, and the fixed frame 443. The collection tray 7 collects the metal powder.

[0028] Motor 3 (451) is started, driving the square shaft 455 and gear 1 (452) to rotate. Because the square shaft 455 is square, and the drive wheel 454 has a corresponding square hole, the shaft rotates synchronously with the drive wheel 454, causing the outer abrasive wire to rotate in a ring. This polishes the screw thread. Gear 1 (452) meshes with and drives gear 2 (453) to rotate. 3. The drive screw 457, which is fixedly connected to it, rotates synchronously, so that the drive screw 457 drives the moving table 456 to slide along the second guide rail 458, thereby driving the drive wheel 454 to rotate and slide along the second guide rail 458. The motor 3 451 is intermittently controlled to rotate forward and reverse, thereby driving the drive wheel 454 to rotate and slide back and forth along the second guide rail 458, so that the drive wheel 454 has a certain degree of lateral contact with the abrasive wire. The metal powder on it is cleaned by the lateral contact force to prevent the abrasive wire from slipping. Furthermore, the transmission assembly 5 includes a motor 51, a worm 52, a gear 53, a worm wheel 54, a gear 55, and a transmission belt 57. Four sets of worms 52 are rotatably connected to the inner side of one outer plate, and a motor 51 is fixedly connected to the inner side of one outer plate. The output end of the motor 51 is fixedly connected to one set of worms 52. Gears 53 are fixedly connected to the outer sides of two sets of worms 52, and gears 55 mesh with the outer sides of gears 53. One end of each of the other two sets of worms 52 and one end of each of the two sets of gears 55 are fixedly connected to pulleys 56. The outer sides of the four sets of pulleys 56 are connected to the transmission belt 57. The pulleys 56 at the gear 55 are rotatably connected to one outer plate, and worm wheels 54 mesh with the outer sides of the worms 52.

[0029] Furthermore, the wire rotation mechanism 6 includes a bearing seat 61, and the four sets of wire rotation assemblies 62 are rotatably connected to the bearing seats 61 on their outer sides. The four sets of bearing seats 61 are fixedly connected to two outer side plates respectively. While the back-and-forth grinding and polishing is being carried out, motor 4 51 is started. Motor 4 51 drives a set of worm gears 52 to rotate. Gear 3 53 on the set of worm gears 52 meshes and drives gear 4 55 to rotate. Pulley 2 56 on gear 4 55 drives the other pulleys 2 56 to rotate synchronously through transmission belt 57. This makes the two sets of worm gears 52 on the upper side rotate in the opposite direction to the two sets of worm gears 52 on the lower side. Through the meshing of worm gears 52 and worm wheel 54, the two sets of wire rotating assemblies 62 on the upper side rotate in the opposite direction to the two sets of wire rotating assemblies 62 on the lower side. The bearing housing 61 includes a bearing housing body 611 and a bearing 612. The bearing 612 is fixedly connected to the outer side of the semi-circular shell 622, and the bearing housing body 611 is fixedly connected to the outer side of the bearing 612. The four sets of bearing housing bodies 611 are fixedly connected to two outer side plates respectively.

[0030] Furthermore, the clamping component 623 includes a moving frame 6231, a connecting rotating block 6232, a moving block 6233, a fixing rod 6234, a second track plate 6236, and a moving rod 6237. Four sets of second track plates 6236 are fixedly connected to the inner side of the semi-circular shell 621. Moving blocks 6233 are slidably connected to the inner side of the second track plate 6236. One end of the moving block 6233 is fixedly connected to the fixing rod 6234, and the other end of the moving block 6233 is rotatably connected to the moving rod 6237. The fixing rod 6234... 34 is rotatably connected to the wire clamping wheel 6235. The track plate 6236 has a rectangular groove corresponding to the moving block 6233. The other end of the moving rod 6237 is rotatably connected to the connecting block 6232. The side of the connecting block 6232 away from the moving rod 6237 is fixedly connected to the moving frame 6231. The inner side of the moving frame 6231 is threadedly connected to the threaded operating rod 10. The outer side of the threaded operating rod 10 is rotatably connected to the rectangular plate. The rectangular plate is fixedly connected to the inner side of the semi-circular shell 622.

[0031] The abrasive wire is sleeved on the outside of the guide wheels 8 and the drive wheel 454, and passes through the vibrating wheel 93 and the clamping wheel 6235. Then, because the moving group 43 is equipped with an electric push rod, the electric push rod pushes the guide wheel 8 on it, thereby causing the abrasive wire to tighten. At the same time, the second motor 321 is started. The second motor 321 drives the threaded rod to rotate, thereby causing the slider to slide on the track. Then, under the action of the push-pull rod 11, the tilting moving table 323 is driven to slide along the tilting fixed table 322. According to the helix angle of the thread of the screw, since the tilting moving table 323 is equipped with an angle scale, the tilting angle of the tilting moving table 323 is made consistent with the helix angle of the thread of the screw. By manually cranking the threaded operating rods 10 at various locations, the threaded operating rods 10 drive the moving frame 6231 to move along the threaded operating rods 10, so that the moving frame 6231, through the moving rod 6237, drives the moving block 6233 and the fixed rod 6234 to move along the track plate 6236 to drive the clamping wheel 6235 towards the abrasive wire until the concave and convex grooves on the clamping wheel 6235 clamp the abrasive wire; Furthermore, two sets of vibrating elements 9 are fixedly connected to the inner side of the semi-circular shell 621. The two sets of vibrating elements 9 are staggered about the abrasive wire. The vibrating element 9 includes an electromagnetic vibrator 91, a connecting bracket 92, and a vibrating wheel 93. The electromagnetic vibrator 91 is fixedly connected to the inner side of the semi-circular shell 621. The connecting bracket 92 is fixedly connected to the other end of the electromagnetic vibrator 91. The vibrating wheel 93 is rotatably connected to the inner side of the connecting bracket 92. The vibrating wheel 93 is in close contact with the abrasive wire.

[0032] While the abrasive wire is rotating in a ring and rotating on its own axis, the electromagnetic vibrator 91 is activated. The electromagnetic vibrator 91 drives the vibrating wheel 93 to vibrate at high frequency through the connecting bracket 92. Since the two sets of vibrating components 9 are staggered about the abrasive wire, the abrasive wire is vibrated at high frequency, which expands the lateral movement amplitude of the abrasive wire and makes the abrasive wire in full contact with the edge and center of the screw thread surface.

[0033] The specific usage and function of this embodiment are as follows: First, connect all the electrical equipment of this polishing machine to the power supply. Place the lead screw to be polished between the tail jack 223 and the pneumatic chuck 235, with one end of the lead screw placed inside the pneumatic chuck 235. Then, supply compressed gas to the pneumatic chuck 235 through an external air supply device, so that the pneumatic chuck 235 clamps the lead screw and pushes the tail jack 222 to slide on the guide rail 221. Then, the other end of the lead screw contacts the tail jack 223, and the tail jack 223 abuts against the lead screw. Since the tail jack 222 is equipped with a limit device, when the tail jack 223 abuts against the lead screw, the limit device is controlled to fix the tail jack 222. At this point, the lead screw to be polished has been placed. The adjustable support wheel 42 is equipped with an electric push rod. The electric push rod pushes the adjustable support wheel 42 so that the support wheel on it contacts the lead screw and provides support for the lead screw. The abrasive wire is attached to the outside of the guide wheels 8 and the drive wheel 454, and passes through the vibrating wheel 93 and the clamping wheel 6235. Then, since the moving group 43 is equipped with an electric push rod, the electric push rod pushes the guide wheel 8 on it, thereby causing the abrasive wire to tighten. At the same time, the second motor 321 is started. The second motor 321 drives the threaded rod to rotate, thereby causing the slider to slide on the track. Then, under the action of the push-pull rod 11, the tilting moving table 323 is driven to slide along the tilting fixed table 322. According to the helix angle of the thread of the screw, since the tilting moving table 323 is equipped with an angle scale, the tilting angle of the tilting moving table 323 is made consistent with the helix angle of the thread of the screw. The moving group 43 drives the abrasive wire to gradually approach the lead screw, until the abrasive wire wraps around one-third of the thread of the lead screw and then stops; The staff manually cranks the threaded operating rods 10 at various locations. The threaded operating rods 10 drive the moving frame 6231 to move along the threaded operating rods 10. This causes the moving frame 6231 to drive the moving block 6233 and the fixed rod 6234 to move along the track plate 6236 and drive the clamping wheel 6235 towards the abrasive wire until the grooves on the clamping wheel 6235 clamp the abrasive wire. Motor 3 (451) is started, driving the square shaft 455 and gear 1 (452) to rotate. Because the square shaft 455 is square, and the drive wheel 454 has a corresponding square hole, the shaft rotates synchronously with the drive wheel 454, causing the outer abrasive wire to rotate in a ring. This polishes the screw thread. Gear 1 (452) meshes with and drives gear 2 (453) to rotate. 3. The drive screw 457, which is fixedly connected to it, rotates synchronously, so that the drive screw 457 drives the moving table 456 to slide along the second guide rail 458, thereby driving the drive wheel 454 to rotate and slide along the second guide rail 458. The motor 3 451 is intermittently controlled to rotate forward and reverse, thereby driving the drive wheel 454 to rotate and slide back and forth along the second guide rail 458, so that the drive wheel 454 has a certain degree of lateral contact with the abrasive wire. The metal powder on it is cleaned by the lateral contact force to prevent the abrasive wire from slipping. While the abrasive wire polishes the screw thread, the linear motor 312 is started. The linear motor 312 drives the sliding block 314 to slide back and forth with the assistance of the drag chain 313, thereby driving the abrasive wire to polish the screw thread back and forth. While the back-and-forth grinding and polishing is being carried out, motor 4 51 is started. Motor 4 51 drives a set of worm gears 52 to rotate. Gear 3 53 on the set of worm gears 52 meshes and drives gear 4 55 to rotate. Pulley 2 56 on gear 4 55 drives the other pulleys 2 56 to rotate synchronously through transmission belt 57. This makes the two sets of worm gears 52 on the upper side rotate in the opposite direction to the two sets of worm gears 52 on the lower side. Through the meshing of worm gears 52 and worm wheel 54, the two sets of wire rotating assemblies 62 on the upper side rotate in the opposite direction to the two sets of wire rotating assemblies 62 on the lower side. While the first semicircular shell 621 and the second semicircular shell 622 are rotating, the concave and convex teeth on the clamping wheel 6235 are clamped with the abrasive wire, and the wire rotation mechanism 6 is distributed at the four corners of the abrasive wire, thereby driving the abrasive wire to rotate and flip, thereby achieving the purpose of abrasive wire contacting the screw thread surface 360 ​​degrees for polishing, which greatly increases the contact area between the abrasive wire and the screw thread surface. While the abrasive wire is rotating in a ring and rotating on its own axis, the electromagnetic vibrator 91 is activated. The electromagnetic vibrator 91 drives the vibrating wheel 93 to vibrate at high frequency through the connecting bracket 92. Since the two sets of vibrating components 9 are staggered about the abrasive wire, the abrasive wire is vibrated at high frequency, which expands the lateral movement amplitude of the abrasive wire and makes the abrasive wire in full contact with the edge and center of the screw thread surface.
