[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The clamping mechanism for polishing a steel ring shown in the figure comprises a workbench 1, a rotating plate 2 is arranged on the top of the workbench 1 through a lifting and rotating assembly, a disc 5 is fixedly installed on the top of the rotating plate 2, a rectangular hole is opened on the top of the disc 5, a bidirectional screw rod 6 is installed on the relative inner walls of the rectangular hole for common rotation, a driving assembly is arranged on the bidirectional screw rod 6, two rectangular frames 10 are threadedly installed on the bidirectional screw rod 6, and clamping assemblies are arranged on the two rectangular frames 10, and the clamping assemblies include a rectangular plate 11, which is fixedly installed on the side of the rectangular frame 10, and the rectangular plate A circular hole is provided on the side of 11 and the rectangular frame 10, in which a sliding shaft 12 is slidably installed, an arc-shaped clamping plate 13 is fixedly installed on one end of the sliding shaft 12, and a slide plate 14 is fixedly installed on the other end of the sliding shaft 12. The slide plate 14 is slidably installed in the rectangular frame 10, and a compression unit is provided on the side of the slide plate 14. Two sliding holes are provided on the side of the rectangular plate 11, and limit plates 16 are slidably installed in the two sliding holes. The two limit plates 16 are connected to the slide plate 14 through a connecting unit, and a grinding wheel 18 is provided on the top of the workbench 1 through an adjusting component.

[0023] With the help of the above structure, when in use, first place the steel ring on the top of the workbench 1, and then drive the bidirectional screw 6 to rotate through the driving assembly, so that the two rectangular frames 10, two rectangular plates 11, two sliding shafts 12, and two arc-shaped clamping plates 13 move synchronously in opposite directions. When the two arc-shaped clamping plates 13 are in contact with the inner wall of the peripheral side of the steel ring, the arc-shaped clamping plates 13, the sliding shafts 12, and the slide plate 14 stop moving under the action of extrusion. At this time, the rectangular frame 10 and the rectangular plate 11 continue to move, and under the action of the two connecting units, the two limit plates 16 are driven to move synchronously toward each other, and the top and bottom ends of the steel ring are clamped and fixed. In this way, the inner wall, top and bottom ends of the peripheral side of the steel ring can be clamped and fixed, and the steel ring can be effectively prevented from sliding downward during the polishing process.

[0024] like Figure 3 As shown, the lifting and rotating assembly includes a lifting hydraulic cylinder 3, which is fixedly installed at the bottom of the workbench 1. The output end of the lifting hydraulic cylinder 3 passes through the workbench 1 and is fixedly installed with a rotating motor 4. The output shaft of the rotating motor 4 is fixedly connected to the bottom of the rotating plate 2. The top of the workbench 1 is provided with an avoidance groove adapted to the disc 5. The advantage of this arrangement is that through the arrangement of the lifting hydraulic cylinder 3 and the rotating motor 4, the rotating plate 2 and the disc 5 can be driven to achieve the lifting and rotating functions.

[0025] Specifically, after the steel ring is clamped and fixed, it is driven to rise to a suitable position by the lifting hydraulic cylinder 3, and then the rotating motor 4 drives the rotating plate 2, the disc 5, and the steel ring to rotate synchronously, thereby realizing the grinding function.

[0026] like Figure 3As shown, the driving assembly includes a clamping motor 9, a device groove is opened on the side of the rectangular hole, the clamping motor 9 is fixedly installed in the device groove, the first bevel gear 7 is fixedly sleeved on the output shaft of the clamping motor 9, the second bevel gear 8 is fixedly sleeved on the bidirectional screw rod 6, and the first bevel gear 7 is meshed with the second bevel gear 8. The advantage of such an arrangement is that the function of driving the bidirectional screw rod 6 to rotate by the clamping motor 9 can be realized through the arrangement of the clamping motor 9 and the first bevel gear 7 and the second bevel gear 8.

[0027] Specifically, the clamping motor 9 is started to drive the first bevel gear 7 to rotate, and then the two-way screw rod 6 is driven to rotate through the meshing action of the first bevel gear 7 and the second bevel gear 8, and then the two rectangular frames 10 are driven to move toward or away from each other synchronously under the action of the thread.

[0028] like Figure 4 As shown, the compression unit includes a compression spring 15, one end of the compression spring 15 is fixedly installed on the side of the slide plate 14, and the other end of the compression spring 15 is fixedly installed on the inner wall of the side of the rectangular frame 10. The advantage of this arrangement is that through the arrangement of the compression spring 15, when the squeezing of the arc-shaped clamping plate 13 is released, the elastic action of the compression spring 15 can drive the slide plate 14, the sliding shaft 12, and the arc-shaped clamping plate 13 to achieve a reset function.

[0029] Specifically, when the compression on the arc clamping plate 13 is released, the elastic action of the compression spring 15 can drive the slide plate 14 to achieve the reset function, and the arc clamping plate 13 can be driven by the slide plate 14 and the sliding shaft 12 to achieve the synchronous reset function without manual operation by the staff.

[0030] like Figure 4 As shown, the connecting unit includes a connecting rod 17, one end of which is rotatably mounted on the side of the limit plate 16, and the other end of the connecting rod 17 is rotatably mounted on a side of the slide plate 14. The top inner wall and the bottom inner wall of the rectangular frame 10 are both provided with connecting holes, and the connecting rod 17 is slidably mounted in the connecting hole. The advantage of such an arrangement is that, through the arrangement of the connecting rod 17, the relative movement of the slide plate 14 and the rectangular plate 11 can be used to drive the limit plate 16 to realize the sliding function.

[0031] Specifically, when the arc-shaped slide plate 13 contacts the steel ring, the arc-shaped slide plate 13, the sliding shaft 12 and the slide plate 14 stop moving due to the squeezing of the steel ring. At this time, the rectangular frame 10 and the rectangular plate 11 continue to move, and the limit plate 16 is driven to slide under the action of the connecting rod 17.

[0032] like Figure 4As shown, the outer wall of the surrounding side of the arc-shaped clamping plate 13 and the opposite sides of the two limit plates 16 are provided with protective pads, and two avoidance holes are opened on the top of the workbench 1, and the two avoidance holes are respectively adapted to the two rectangular plates 11. The advantage of such a setting is that through the setting of the protective pads, the limit plates 16 and the arc-shaped clamping plates 13 can play a protective role when they are squeezed and fixed.

[0033] Specifically, when the arc-shaped clamping plate 13 and the two limiting plates 16 clamp and fix the steel ring, the provision of the protection pad can protect the steel ring and prevent the steel ring from being worn.

[0034] like Figure 1 As shown, the adjustment component includes a side plate 19, and an adjusting hydraulic cylinder 20 is fixedly installed on the side of the side plate 19. The output end of the adjusting hydraulic cylinder 20 passes through the side plate 19 and is fixedly connected to one end of the grinding wheel 18. The advantage of this arrangement is that the position of the grinding wheel 18 can be adjusted by adjusting the setting of the hydraulic cylinder 20, which is convenient for grinding steel rims of different sizes.

[0035] Specifically, when the position of the grinding wheel 18 needs to be adjusted, the grinding wheel 18 is driven to move by adjusting the hydraulic cylinder 20, so that the position of the grinding wheel 18 is adjusted, thereby achieving grinding of steel rings of different sizes.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
