[0003] For example, the patent publication number CN219113676U is a rotary grinding head for plate rolling processing. Through the design of the support block, the connecting block of the grinding plate is clamped inside the clamping slot. The rotating grinding plate enables the connecting block to rotate to the inside of the semicircular groove. The grinding plate is fixed by the clamping block. During the installation and disassembly process, there is no need to use professional tools to install and disassemble the grinding plate. It is reinforced by bolts, which facilitates operation, increases convenience and work efficiency.

[0004] However, in actual use, since the objects to be polished have different surface curvatures, workers need to constantly adjust the angle of the polishing disc when polishing the objects, which reduces the polishing rate of the objects and the applicability of the device. Therefore, the applicant proposes a high-efficiency rotary polishing head. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] In all walks of life, in order to improve the appearance of products, it is often necessary to polish the products. Therefore, an efficient rotary polishing head is needed. In actual use, most traditional polishing heads have different curvatures on the surface of objects due to the different types and styles of objects. When polishing objects, it is necessary to continuously adjust the polishing head so that the polishing head can better contact with the surface of the object, which reduces the applicability of the device and the polishing rate of the object. For this reason, the applicant proposes an efficient rotary polishing head.

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: an efficient rotary grinding head, including a grinding sheet 1, a changing mechanism 2 is clamped on the top of the grinding sheet 1, the changing mechanism 2 includes a shell 201, and movable rods 202 are rotatably connected on both sides of the outer wall of the shell 201, one side of one movable rod 202 is fixed with a rope 203, one end of the rope 203 passes through both sides of the outer wall of the shell 201 and is fixed to one side of the other movable rod 202, and the middle part of the rope 203 is located inside the shell 201, and a pressing plate 204 is slidably connected to the inner wall of the shell 201, and the bottom of the pressing plate 204 contacts the middle part of the rope 203, a plurality of telescopic rods 205 are fixed on the top of the pressing plate 204, a plurality of first springs 206 are fixed on the top of the pressing plate 204, and the plurality of telescopic rods 205 are respectively located inside the plurality of first springs 206, and the plurality of A connecting column 207 is fixed to the top of a first spring 206 and a plurality of telescopic rods 205, and the lower end of the connecting column 207 is slidably connected to the inner wall of the shell 201, and the control mechanism 3 is clamped on the top of the changing mechanism 2, and the top of the changing mechanism 2 is located inside the lower end of the control mechanism 3. Blocks 208 are fixed to both sides of the top of the connecting column 207, and fixing frames 209 are fixed to one end of the two movable rods 202, and a cushion 210 is fixed to the bottom of the two fixing frames 209. The center position of the top of the cushion 210 is rotatably connected to the lower end of the shell 201, and the sum of the lengths of the two fixing frames 209 is less than the length of the cushion 210. The lengths of the two movable rods 202 are equal, and the lengths of the two movable rods 202 are both greater than the height of the shell 201, and the length of the rope 203 is greater than or equal to the height of the shell 201.

[0023] It should be noted that when grinding an object, when the grinding sheet 1 contacts the object, due to the flexibility of the soft pad 210 and the rotational connection between the shell 201 and the soft pad 210, the grinding sheet 1 can make good contact with the surface of the object. Subsequently, through the continuous descent of the device, the connecting column 207 is also subjected to pressure and will also descend. At this time, the pressure plate 204 will exert pressure on the rope 203. Due to the elasticity of its first spring 206, hard contact with the rope 203 can be avoided. Subsequently, under the continuous contraction of the rope 203, the two movable rods 202 will respectively control the two fixed frames 209 to clamp and fix the two ends of the soft pad 210, thereby completing the grinding operation of the object.

[0024] like Figure 4As shown, the utility model provides a technical solution: a high-efficiency rotary grinding head, including a control mechanism 3, the control mechanism 3 includes a connecting shell 301, the inner wall of the connecting shell 301 is respectively provided with a card slot 302, the inner wall of the connecting shell 301 is respectively provided with a sliding slot 303 on the other two sides, a fixing box 304 is fixed on the top of the connecting shell 301, a second spring 305 is fixed on the top of the inner wall of the fixing box 304, a stretching rod 306 is fixed on the top of the inner wall of the fixing box 304, the stretching rod 306 is located inside the second spring 305, one end of the stretching rod 306 is rotatably connected to a rotating plate 307, and one end of the second spring 305 It is in contact with the top of the rotating plate 307, and the top of the fixed box 304 is rotatably connected to the fixed block 308.

The height of the second spring 305 is equal to the height of the stretching rod 306, and is greater than or equal to the sum of the heights of the fixed box 304 and the slot 302. The shortest height of the second spring 305 is less than the height of the fixed box 304.

[0025] It should be noted that when disassembling or installing the changing mechanism 2, first align the two blocks 208 in the changing mechanism 2 with the two sliding grooves 303, and insert the connecting column 207 into the connecting shell 301. At this time, the connecting column 207 will contact the rotating plate 307. When the two blocks 208 are disengaged from the two sliding grooves 303, rotate the changing mechanism 2 to make the two blocks 208 and the two slots 302 engage with each other. Under the action of the second spring 305, the rotating plate 307 will clamp and fix the connecting column 207. Subsequently, when grinding the object, start the motor 309 to drive the control mechanism 3 and the changing mechanism 2 to rotate, thereby completing the grinding operation of the object.
