[0010] A connecting rod is fixedly installed on the outer surface of the movable rod. One end of the connecting rod extends to the outside of the side wall of the disc body through a limiting groove, and an expansion block is fixedly installed on one end of the connecting rod.

[0011] As a further description of the above technical solution:

[0012] A support plate is fixedly installed on the upper surface of the rotating disk, and a positioning spring is fixedly installed on the side wall of the support plate.

[0013] As a further description of the above technical solution:

[0014] A fixing plate is fixedly installed at one end of the positioning spring, and a positioning rod is fixedly installed on the side wall of the fixing plate.

[0015] As a further description of the above technical solution:

[0016] One end of the positioning rod passes through the interior of the positioning spring and extends to the outside of the other side wall of the support plate, and the positioning sleeve is fixedly installed on the outer surface of the self-locking threaded sleeve.

[0017] As a further description of the above technical solution:

[0018] The outer surface of the positioning sleeve is provided with a positioning hole, and one end of the positioning rod is adapted to the positioning hole.

[0019] As a further description of the above technical solution:

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by setting an adjustment component, when it is necessary to replace the polishing pad with a larger size, one end of the positioning rod is disengaged from the positioning hole, and then the rotating disk rotates on the upper surface of the disk body. As the rotating disk rotates, the moving rod will move in the limiting groove under the action of the stroke groove. At this time, the moving rod moves outward in the limiting groove of the disk body. When the moving rod moves, it drives the connecting rod to move, thereby driving the expansion block to move outward under the action of the connecting rod. Then, under the action of the positioning spring and the fixing disk, one end of the positioning rod is inserted into the positioning hole on the positioning sleeve. The expansion block is fixed by fixing the rotating disk, thereby adjusting the overall area of ​​the disk body. Then, the larger polishing pad is glued to the disk body. It can be used for polishing pads of different sizes without replacing the disk body, which improves the applicability of the composite polishing disk and also improves the practicality of the composite polishing disk, further demonstrating the convenience of the composite polishing disk.

[0023] 2. In this utility model, by setting an asphalt layer, the disc body is fixedly connected to the polishing machine by a self-locking threaded sleeve. Then, the polishing skin with self-adhesive backing is bonded to the asphalt layer on the lower surface of the disc body. Then, the polishing machine drives the disc body to rotate, which in turn drives the polishing skin to rotate, thereby performing the polishing operation. Compared with the traditional polyurethane polishing disc, it can better control the surface shape of the polishing skin and improve the operability of the composite polishing disc.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a cold working polishing composite polishing disc, including a disc body 1, a self-locking threaded sleeve 2 fixedly installed on the upper surface of the disc body 1, and an adjustment component 5 provided on the upper surface of the disc body 1;

[0032] The adjusting assembly 5 includes a rotating disk 51 and a limiting groove 53. The lower surface of the rotating disk 51 is rotatably connected to the upper surface of the disk body 1. One end of the self-locking threaded sleeve 2 extends to the outside of the upper surface of the rotating disk 51. A travel groove 52 is provided on the upper surface of the rotating disk 51. The limiting groove 53 is located outside the upper surface of the disk body 1. A moving rod 54 is slidably installed on the inner wall of the limiting groove 53. One end of the moving rod 54 extends to the outside of the upper surface of the rotating disk 51 through the travel groove 52. A connecting rod 55 is fixedly installed on the outer surface of the moving rod 54. One end of the connecting rod 55 extends to the outside of the side wall of the disk body 1 through the limiting groove 53. An expansion block 56 is fixedly installed at one end of the connecting rod 55. A support plate 57 is fixedly installed on the upper surface of the rotating disk 51. A positioning spring 58 is fixedly installed on the side wall of the support plate 57. A fixing plate 59 is fixedly installed at one end of the positioning spring 58. A positioning rod 510 is fixedly installed on the side wall of the fixing plate 59. One end of the positioning rod 510 passes through the interior of the positioning spring 58 and extends to the outside of the other side wall of the support plate 57. A positioning sleeve 6 is fixedly installed on the outer surface of the self-locking threaded sleeve 2. A positioning hole 7 is provided on the outer surface of the positioning sleeve 6. One end of the positioning rod 510 is adapted to the positioning hole 7.

[0033] The specific implementation method is as follows: When it is necessary to replace the polishing skin 4 with a larger size, one end of the positioning rod 510 is disengaged from the positioning hole 7, and then the rotating disk 51 is rotated on the upper surface of the disk body 1. As the rotating disk 51 rotates, the moving rod 54 will move in the limiting groove 53 under the action of the stroke groove 52. At this time, the moving rod 54 moves to the outside of the disk body 1 in the limiting groove 53. When the moving rod 54 moves, it drives the connecting rod 55 to move, thereby driving the expansion block 56 to move to the outside of the disk body 1 under the action of the connecting rod 55. Then, under the action of the positioning spring 58 and the fixing disk 59, one end of the positioning rod 510 is inserted into the positioning hole 7 on the positioning sleeve 6. The expansion block 56 is fixed by fixing the rotating disk 51, thereby adjusting the overall area of ​​the disk body 1. Then, the polishing skin 4 with a larger size is glued to the disk body 1.

[0034] The lower surfaces of the disc body 1 and the expansion block 56 are both covered with an asphalt layer 3, and a polishing skin 4 is fixedly installed on the lower surface of the asphalt layer 3. The outer surface of the polishing skin 4 has self-adhesive backing.

[0035] The specific implementation method is as follows: the disc body 1 is fixedly connected to the polishing machine by the self-locking threaded sleeve 2, and then the polishing skin 4 with self-adhesive backing is bonded to the asphalt layer 3 on the lower surface of the disc body 1. Then the polishing machine drives the disc body 1 to rotate, which in turn drives the polishing skin 4 to rotate, thereby performing the polishing operation. The asphalt layer 3 is poured on the disc body 1, and then the asphalt layer 3 is trimmed and flattened.

[0036] Working principle: The disc body 1 is fixedly connected to the polishing machine via the self-locking threaded sleeve 2. Then, the self-adhesive polishing pad 4 is bonded to the asphalt layer 3 on the lower surface of the disc body 1. The polishing machine drives the disc body 1 to rotate, which in turn drives the polishing pad 4 to rotate, thus performing the polishing operation. When a larger polishing pad 4 needs to be replaced, one end of the positioning rod 510 is disengaged from the positioning hole 7, and then the rotating disc 51 rotates on the upper surface of the disc body 1. As the rotating disc 51 rotates, the moving rod 54 moves in the limit groove under the action of the stroke groove 52. The moving rod 54 moves outward from the limit groove 53. When the moving rod 54 moves, it drives the connecting rod 55 to move, thereby driving the expansion block 56 to move outward from the plate body 1 under the action of the connecting rod 55. Then, under the action of the positioning spring 58 and the fixing plate 59, one end of the positioning rod 510 is inserted into the positioning hole 7 on the positioning sleeve 6. The expansion block 56 is fixed by fixing the rotating plate 51, thereby adjusting the overall area of ​​the plate body 1. Then, the larger polishing skin 4 is glued to the plate body 1.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
