[0002] The screw thread surface polishing machine is a device specially used for polishing the screw thread to improve the surface finish and processing accuracy of the screw thread. The screw thread surface polishing machines on the market are mainly divided into three main types: fluid polishing machine, polishing wheel polishing machine, and abrasive belt polishing machine.

[0003] The existing screw thread surface polishing machines mainly have the following technical defects: among the three existing polishing machines used for screw thread surface polishing, the fluid polishing machine has sufficient contact area with the screw thread, but its polishing force is relatively insufficient, and both types of polishing machines, namely the polishing wheel polishing machine and the frosted belt polishing machine, have the problem of small contact area with the screw thread, which makes the contact degree between their respective polishing media and the screw thread poor. Therefore, compared with these three types of polishing machines, polishing machines using frosted wire surface polishing for screw thread surface polishing have been further developed. Among them, although the traditional frosted wire polishing increases the contact area and polishing force of the screw thread surface, there is still an area where the frosted wire is not in contact with the screw thread surface, and thus there are still problems of low polishing efficiency and low abrasive utilization.

[0014] The frosted wire is sleeved on the outside of the guide wheels and the driving wheel at various places, and passes through the vibrating wheel and the wire clamping wheel. Then, since the moving group is provided with an electric push rod, the electric push rod pushes the guide wheel thereon, thereby driving the frosted wire to be tightened. 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 platform is driven to slide along the tilting fixed platform. According to the helical angle of the thread of the screw rod, since the angle scale is provided on the tilting moving platform, the tilting moving platform is driven to an inclination angle consistent with the helical angle of the thread of the screw rod. By manually cranking the threaded operating rods at various locations, the threaded operating rods drive the motion frame to move along the threaded operating rods, so that the motion frame drives the moving block and the fixed rod along the track plate to drive the wire clamping wheel to move toward the frosted wire until the concave and convex tooth grooves on the wire clamping wheel are clamped with the frosted wire; Furthermore, two groups of vibrators are fixedly connected to the inner side of the semicircular shell one, and the two groups of vibrators are staggered with respect to the frosted wire.

[0015] While the frosted wire is rotating in a circle and on its own, the electromagnetic vibrator is started, and the electromagnetic vibrator drives the vibration wheel to vibrate at high frequency through the connecting bracket. Since the two groups of vibrators are staggered about the frosted wire, high-frequency vibration of the frosted wire is achieved, thereby expanding the lateral movement amplitude of the frosted wire, so that the frosted wire is in full contact with the edge and center parts of the screw thread surface.

[0016] Compared with the prior art, the present invention provides a screw thread surface polishing machine, which has the following beneficial effects: 1.

[0017] 2. The screw thread surface polishing machine realizes the purpose of the frosted wire rotating on its own while performing circular rotation through the cooperation between the transmission group and the wire rotating mechanism, so that the frosted wire is in 360-degree contact with the screw thread surface for polishing, greatly improving the contact area between the frosted wire and the screw thread surface, so that the frosted wire is in full contact with the screw thread surface, greatly improving the utilization rate of the frosted wire, saving abrasives, and solving the problem that the existing frosted wire still has an area that is not in contact with the screw thread surface, and thus still has low polishing efficiency and low abrasive utilization.

[0018] 3. The screw thread surface polishing machine has vibrating parts staggeredly distributed on the outside of the frosted wire and in close contact with the frosted wire, so that the electromagnetic vibrator drives the vibrating wheel to vibrate at high frequency, thereby achieving high-frequency vibration of the frosted wire, thereby expanding the lateral movement amplitude of the frosted wire, so that the frosted wire is in full contact with the edge and center parts of the screw thread surface, preventing the frosted wire from grinding the screw thread surface with dead angles, thereby improving the overall polishing quality.

Then, under the action of the push-pull rod 11, the tilting moving platform 323 is driven to slide along the tilting fixed platform 322. According to the helical angle of the thread of the screw rod, since the tilting moving platform 323 is provided with an angle scale, the tilting moving platform 323 is driven to an inclination angle consistent with the helical angle of the thread of the screw rod. By manually cranking the threaded operating rods 10 at various locations, the threaded operating rods 10 drive the motion frame 6231 to move along the threaded operating rods 10, so that the motion frame 6231 drives the moving block 6233 and the fixed rod 6234 along the track plate 6236 to drive the wire clamping wheel 6235 to move toward the frosted wire, through the motion rod 6237, until the concave and convex tooth grooves on the wire clamping wheel 6235 are clamped with the frosted wire; Furthermore, two groups of vibrators 9 are fixedly connected to the inner side of the semicircular shell 621, and the two groups of vibrators 9 are staggered about the frosted wire.

[0032] While the frosted wire is rotating in a circle and on its own, the electromagnetic vibrator 91 is started, and the electromagnetic vibrator 91 drives the vibration wheel 93 to vibrate at high frequency through the connecting bracket 92. Since the two groups of vibrators 9 are staggered with respect to the frosted wire, high-frequency vibration of the frosted wire is achieved, thereby expanding the lateral movement amplitude of the frosted wire, so that the frosted wire is in all-round contact with the edge and center parts of the screw thread surface.

[0033] The specific usage and function of this embodiment are as follows: First, connect all electrical equipment of the polishing machine to a power source, place the screw to be polished between the tail top 223 and the pneumatic chuck 235, wherein one end of the screw is placed on the inner side of the pneumatic chuck 235, and then introduce compressed gas into the pneumatic chuck 235 through an external air supply device, so that the pneumatic chuck 235 clamps the screw, and pushes the tail top platform 222 to slide on the guide rail 1 221, and then the other end of the screw contacts the tail top 223, and the tail top 223 abuts against the screw.

At the same time, the motor 2 321 is started, and the motor 2 321 drives the threaded rod to rotate, thereby driving the slider to slide on the track. Then, under the action of the push-pull rod 11, the tilting moving platform 323 is driven to slide along the tilting fixed platform 322. According to the helical angle of the thread of the screw rod, since the tilting moving platform 323 is provided with an angle scale, the tilting moving platform 323 is driven to an inclination angle consistent with the helical angle of the thread of the screw rod. The moving group 43 drives the frosted wire to gradually approach the screw rod until the frosted wire wraps around one third of the screw rod thread and stops; The staff manually cranks the threaded operating rods 10 at various locations, and the threaded operating rods 10 drive the motion frame 6231 to move along the threaded operating rods 10, so that the motion frame 6231 drives the moving block 6233 and the fixed rod 6234 along the track plate 6236 to drive the wire clamping wheel 6235 to move toward the frosted wire, through the motion rod 6237, until the concave and convex tooth grooves on the wire clamping wheel 6235 are clamped with the frosted wire; The motor 3 451 is started, and the motor 3 451 drives the square shaft 455 and the gear 1 452 to rotate.
