[0034] In this embodiment, a rotating column 17 is connected between the limiting seat 16 and the limiting bracket 14 , a limiting stopper 18 is fixedly installed on the top of the limiting bracket 14 , and a clamping joint 19 is fixedly installed on the bottom of the linkage frame 15 .

[0035] The lifting frame 5 descends and drives the linkage frame 15 to descend together. The linkage frame 15 drives the clamping joint 19 to contact the limit seat 16 to move it, and the limit block 18 limits the limit seat 16.

[0036] In this embodiment, the limiting seat 16 is rotatably connected to the limiting bracket 14 via the rotating column 17 , and the limiting seat 16 is flush with the top end of the limiting bracket 14 after being turned over.

[0037] The limit seat 16 is flipped relative to the limit bracket 14 through the rotating column 17. When the limit seat 16 is flipped to be flush with the top end of the limit bracket 14, the limit protection structure 13 composed of the limit bracket 14, the limit seat 16 and the limit block 18 limits the descending height of the lifting frame 5, thereby limiting the descending height of the polishing device head, which can avoid excessive contact between the polishing part of the polishing device and the metal workpiece.

[0038] In this embodiment, an indicator frame 20 is fixedly mounted on the outer side of the fixing frame 2, a connecting frame 21 is connected to the outer side of the linkage frame 15, an indicator plate 22 is fixedly connected to the outer surface of the indicator frame 20, and the connecting frame 21 moves synchronously with the linkage frame 15.

[0041] The connecting frame 21 drives the L-shaped block 24 to slide along the L-shaped groove 23 inside the indicating frame 20, and can drive the indicating head 25 to move together. By observing the position of the indicating head 25 on the indicating plate 22, the working position of the polishing device can be accurately indicated.

[0042] In this embodiment, a motor 26 is fixedly installed near one end of the top of the loading rack 3, and the output end of the motor 26 is connected to a socket 27 through a rotating shaft. A tubular workpiece 28 is arranged on the inner side of the socket 27. A threaded rod 29 is threadedly connected to the top of the loading rack 3 near the other end, and a support frame 30 is connected to the end of the threaded rod 29. A tightening head 31 adapted to the tubular workpiece 28 is arranged on the inner side of the support frame 30.

[0043] One end of the tubular workpiece 28 is sleeved on the socket 27 , and the abutting head 31 on the support frame 30 abuts against the other end of the tubular workpiece 28 , so that the tubular workpiece 28 is installed on the loading frame 3 .

[0044] In this embodiment, a hand wheel 32 is connected to one end of the threaded rod 29, and a guide sleeve 33 is symmetrically arranged on the outer side of the loading rack 3. A guide rod 34 connected to the support frame 30 is penetrated inside the guide sleeve 33, and the support frame 30 is movably connected to the loading rack 3 through the threaded rod 29.

[0045] By turning the hand wheel 32, the threaded rod 29 rotates accordingly and engages with the loading rack 3, which can provide power for the movement of the support frame 30. The support frame 30 moves relative to the loading rack 3 through the threaded rod 29. The support frame 30 drives the clamping head 31 to clamp the end of the tubular workpiece 28, and the guide rod 34 cooperates with the guide sleeve 33 to guide the movement of the support frame 30.

[0046] In this embodiment, a guide seat 35 is fixedly installed at the bottom of the loading rack 3, a movable seat 36 is arranged inside the guide seat 35, a lifting frame 37 is fixedly connected inside the movable seat 36, and an arc groove is opened on the top of the lifting frame 37.

[0047] The movable seat 36 moves along the guide seat 35 to a suitable lifting position, and the lifting frame 37 assists in supporting the metal workpiece to prevent the metal workpiece from being offset when being loaded, and can facilitate alignment of the metal workpiece when being loaded, thereby improving the loading efficiency of the polishing device.

[0048] In this embodiment, a slider 38 that is inserted into the interior of the guide seat 35 is fixedly installed on the outer surface of the movable seat 36, and a slide groove 39 that matches the slider 38 is inserted into the inner side of the guide seat 35. The outer side of the lifting frame 37 is connected to a connector 40 that is inserted into the interior of the movable seat 36. A telescopic spring 41 is connected between the connector 40 and the movable seat 36, and a positioning column 42 is connected to the interior of the connector 40.

[0049] The guide seat 35 moves to the position below the metal workpiece through the slider 38 and the slide groove 39, and the telescopic spring 41 resets the push-up connector 40 to lift the lifting frame 37. After the lifting frame 37 is lifted, it contacts the metal workpiece to assist in supporting it.

[0050] In this embodiment, the movable seat 36 is slidably connected to the guide seat 35 through a slider 38 and a slide groove 39 , and the lifting frame 37 is movably connected to the movable seat 36 through a connector 40 , a telescopic spring 41 and a positioning column 42 .

[0051] Press the lifting frame 37, and the lifting frame 37 will move relative to the movable seat 36 through the connector 40, the telescopic spring 41 and the positioning column 42, so as to separate the lifting frame 37 from the metal workpiece; pull the lifting frame 37, and the movable seat 36 will slide relative to the guide seat 35 through the slider 38 and the slide groove 39, so that the lifting frame 37 can be easily moved out.

[0052] It should be noted that the present invention is a metal workpiece polishing device. When in use, the movable seat 36 moves along the guide seat 35 to a suitable lifting position, and the lifting frame 37 assists in supporting the tubular workpiece 28. One end of the tubular workpiece 28 is sleeved on the socket head 27, and the hand wheel 32 is turned, and the threaded rod 29 rotates accordingly and meshes with the loading frame 3, which can provide power for the movement of the support frame 30. The support frame 30 moves relative to the loading frame 3 through the threaded rod 29, and the guide rod 34 cooperates with the guide sleeve 33 to guide the movement of the support frame 30. The support frame 30 drives the tightening head 31 to tighten the end of the tubular workpiece 28, and the tightening head 31 on the support frame 30 tightens the other end of the tubular workpiece 28, so as to realize the installation of the tubular workpiece 28 on the loading frame 3;

[0053] After the tubular workpiece 28 is installed, the lifting frame 37 is pressed, and the lifting frame 37 moves relative to the movable seat 36 through the joint 40, the telescopic spring 41 and the positioning column 42, so that the lifting frame 37 is separated from the metal workpiece. The lifting frame 37 is pulled, and the movable seat 36 slides relative to the guide seat 35 through the slider 38 and the slide groove 39, so that the lifting frame 37 can be easily moved out;

[0054] The motor 26 is started, and the motor 26 drives the tubular workpiece 28 to rotate at high speed through the socket 27. The No. 1 cylinder 4 is started, and the No. 1 cylinder 4 drives the lifting frame 5 to descend. When the lifting frame 5 descends, the frame 7 also descends. The frame 7 drives the polishing head 10 to contact the high-speed rotating tubular workpiece 28 to polish its surface. The No. 2 cylinder 11 is started, and the No. 2 cylinder 11 drives the machine base 9 through the driving frame 12. The machine base 9 moves along the crossbeam 8 to polish different positions of the tubular workpiece 28.

[0055] The lifting frame 5 descends and drives the linkage frame 15 to descend together. The linkage frame 15 drives the clamping joint 19 to contact the limit seat 16 to move it. The limit block 18 limits the limit seat 16. The limit seat 16 is turned over relative to the limit bracket 14 through the rotating column 17. When the limit seat 16 is turned over to be flush with the top end of the limit bracket 14, the limit protection structure 13 composed of the limit bracket 14, the limit seat 16 and the limit block 18 limits the descending height of the lifting frame 5, so as to limit the descending height of the polishing device head, thereby avoiding the phenomenon that the polishing part of the polishing device and the metal workpiece are in excessive contact.

[0056] The connecting frame 21 moves synchronously with the linkage frame 15. The connecting frame 21 drives the L-shaped block 24 to slide along the L-shaped groove 23 inside the indicating frame 20, and can drive the indicating head 25 to move together to observe the position of the indicating head 25 on the indicating plate 22. The indicating frame 20 cooperates with the indicating plate 22 and the indicating head 25 to accurately indicate the descending position of the polishing device head, so as to facilitate the polishing device to perform polishing processing at a suitable workstation.
