The driving unit 2 includes a fixed frame 20 fixed on the base 1, and a machine cover 21 is provided on the outer cover of the fixed frame 20. A servo motor 22 is provided at the upper end of the fixed frame 20, and a screw 23 extending to the movable platform 41 is provided at the lower end. The screw 23 is threadedly connected to the connecting member 42. The output shaft of the servo motor 22 extends out of the machine cover 21. The output shaft of the servo motor 22 located in the machine cover 21 is sleeved with a transmission wheel 24 that is transmission-connected to the screw 23. A clamp 25 is fixed on the output shaft outside the machine cover 21, and the clamp 25 is arranged opposite to the polishing machine 44. The connecting member 42 includes an extension plate 46 fixed on the movable platform 41, and a lower connecting block 460 and an upper connecting block 461 are sequentially provided on the extension plate 46, and a thread groove 462 is provided on the lower connecting block 460 and the upper connecting block 461. The thread grooves 462 of the lower connecting block 460 and the upper connecting block 461 are interlocked to form a threaded hole for the screw rod 23 to pass through, and the lower connecting block 460 is respectively provided with limiting columns 463 on both sides of the thread groove 462, and the upper connecting block 461 is provided with limiting holes 464 that cooperate with the limiting columns 463. The polishing part 4 also includes a dustproof plate 47 and a dustproof cover 48. The dustproof cover 48 is in a strip shape and is buckled on the screw 23. The upper connecting block 461 is located in the dustproof cover 48. Both sides of the dustproof cover 48 are provided with slots 480 that cooperate with the lower connecting block 460. The dustproof plate 47 is located between the fixed plate 43 and the storage table 3. The dustproof plate 47 is fixed on the dustproof cover 48. The limiting columns 463 arranged on the lower connecting block 460 extend out of the upper ends of the dustproof cover 48 and the dustproof plate 47. The dustproof plate 47 is also provided with a lifting member 5, and the lifting member 5 includes an L-shaped block 50, a bracket 51 and a rotating handle 52. The L-shaped block 50 is fixed on the upper connecting block 461, and one end of the L-shaped block 50 is arranged horizontally and is located below the screw 23 in a gap. The bracket 51 is arranged between the two fixed plates 43, and the rotating handle 52 is rotatably connected to the bracket 51. The end of the rotating handle 52 is fixedly connected to the dustproof plate 47 through a chain 53.The polishing machine 44 is rotatably fixed on the fixed plate 43 through the adjusting member 6, and the adjusting member 6 includes a rotating block 60 rotatably fixed to the inner side of the two fixed plates 43 through bolts, and multiple groups of adjusting holes 431 are evenly arranged on the fixed plate 43. The polishing machine 44 is located between the two rotating blocks 60, and a first arc plate 61 matching with the polishing machine 44 is provided below the two rotating blocks 60, and a second arc plate 62 is provided above the two rotating blocks 60. Bolts are respectively provided on both sides of the second arc plate 62 to be fixed to the rotating block 60, and a shock-absorbing plate 63 is provided between the first arc plate 61, the second arc plate 62 and the polishing machine 44. The provision of the shock-absorbing plate 63 can achieve an effective shock-absorbing effect, so that the polishing machine 44 can polish the valve more stably, thereby improving the polishing accuracy.

[0023] Furthermore, the servo motor 22 has a speed reducer 7, and a speed regulating valve 70 of the speed reducer 7 is located outside the machine cover 21. By providing the speed reducer 7 on the servo motor 22, people can adjust the polishing speed, thereby controlling the polishing feed amount. The slower the speed, the greater the polishing feed amount, and vice versa, the smaller the polishing feed amount, which is very convenient to use.

[0024] Furthermore, the movable platform 41 is also provided with an inductive stopper 8, which includes an inductive head 80 provided on one side of the fixed plate 43 and a movable contact 81 provided on the track 40, and the movable contact 81 is located at one end of the track 40 close to the driving part 2. By providing the inductive stopper 8 on the movable platform 41, the valve can be automatically shut down when the polishing is completed.

[0025] Furthermore, a second adjustment hole 432 for fixing the elastic member 45 is arranged at the lower end of the fixing plate 43 .

[0026] Furthermore, rollers 410 cooperating with the track 40 are provided on both sides of the moving platform 41 .

[0027] Working principle: When people use this device, they first clamp the valve on the fixture 25 and fix it, and then start the servo motor. Since the servo motor 22 has a reducer 7, the fixture 25 will drive the valve to rotate slowly and evenly. At the same time, the servo motor 22 will also drive the screw 23 to rotate. During the rotation of the screw 23, the connecting piece 42 will drive the moving platform 41 to move toward the driving part 2. During the movement of the moving platform 41, people can manually press down the polisher 44 so that the end of the polisher 44 is lifted and then aligned with the valve interface. When the moving platform 41 drives the polisher 44 to enter the valve interface, release the polisher 44. At this time, the polisher 44 will automatically rotate downward and contact the valve interface due to the restoring force of the elastic member 45. Then people can start the polisher 44 to polish the valve. The whole process is very convenient and fast, and no operation is required in the middle. During the rotation of the valve, the moving platform 41 will drive the polisher 44 to gradually penetrate into the valve for polishing, which is very practical. When the valve body is polished, the polishing part 4 can be quickly returned to its original position. When returning to its original position, the rotating handle 52 is pressed downward so that the rotating handle 52 can lift the dust plate 47. At this time, the dust plate 47 drives the dust cover 48 to lift upward. At this time, the upper connecting block 461 located in the dust cover 48 will be separated from the lower connecting block 460, and the L-shaped clamping block 50 set on the upper connecting block 461 will hold the screw 23 against and lift it. At this time, the screw 23 will be separated from the threaded hole formed between the lower connecting block 460 and the upper connecting block 461. Since it is separated from the restriction of the screw 23, people can quickly push the polishing part 4 back to its original position. After returning to its original position, the force applied to the rotating handle 52 is stopped, so that the lower connecting block 460 and the upper connecting block 461 are re-engaged with the screw 23 to form a threaded match, which is very fast and practical. The polishing device of the present invention only needs to install the valve on the fixture 25 when in use to perform fully automatic polishing, which can significantly improve the efficiency of polishing processing.

[0028] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
