The present invention is directed to the above-mentioned disadvantages, and provides an adjustable mirror polishing head, which is an adjustable mirror polishing head with low cost and convenient use.
The technical scheme adopted by the invention is as follows: the adjustable mirror grinding head comprises a handle part and a grinding disc, wherein a grinding surface is arranged below the grinding disc, and the mirror grinding head is in an inverted T-shaped structure in a longitudinal section; the method is characterized in that: the handle is provided with threads, the handle also comprises an adjusting disc, a nut matched with the threads is arranged in the middle of the adjusting disc, a plurality of downward and outward extending connecting rods are arranged around a screw hole, a top disc is connected below the connecting rods, the top disc is an annular body on the grinding surface, edges clamped by a wrench are arranged around the screw hole, the nut is arranged on the threads, and the top disc is propped against the upper surface of the grinding disc.
Furthermore, the adjusting discs are multiple, the adjusting discs are divided into different sizes, and the large adjusting disc is installed outside the small adjusting disc.
Furthermore, the top disc is provided with a small screw hole facing downwards, and a small screw is arranged in the small screw hole.
Furthermore, the top disc is provided with a downward through hole, a small screw is arranged in the through hole, and the grinding surface is provided with a grinding surface screw hole matched with the small screw.
Further, the polishing head also includes a plurality of pads.
Further, the thickness of the gasket is not the same.
Furthermore, the device also comprises one or more ejector rods arranged between the screw hole and the top disc, and a stretching mechanism is arranged in the middle of each ejector rod.
The invention has the beneficial effects that: the mirror grinding head has the advantages of being adjustable in use, low in use cost and convenient to use.

FIG. 1 is a schematic longitudinal sectional view of the present invention.
Fig. 2 is a schematic top view of the present invention.
Wherein: 1. shank 11, screw thread 2, grinding disc 21, grinding surface 3, adjusting disc 31, screw thread 32, connecting rod 33, top disc 34, ridge 35, small screw hole 4, ejector rod 41 and stretching mechanism.
Detailed Description
The invention is further described below with reference to the figures and examples.
As shown in fig. 1 and 2, the adjustable mirror polishing head comprises a handle 1 and a polishing disc 2, wherein a polishing surface 21 is arranged below the polishing disc, and the mirror polishing head has an inverted T-shaped structure in a longitudinal section; the method is characterized in that: the handle is provided with threads 11 and further comprises an adjusting disc 3, a nut 31 matched with the threads is arranged in the middle of the adjusting disc, a plurality of downward and outward extending connecting rods 32 are arranged around a screw hole, a top disc 33 is connected to the lower portion of each connecting rod, the top disc is an annular body on the grinding surface, edges 34 clamped by a wrench are arranged around the screw hole, the nut is arranged on the threads 11, and the top disc is abutted to the upper portion of the grinding disc.
When the grinding head is used, the phenomenon that the grinding surface where the A, B part is located is worn, namely the phenomenon that the periphery of the grinding surface is warped upwards often occurs, the edge 34 can be screwed downwards by a wrench, the connecting rod acts on the top disc 33, a downward acting force F is generated, the grinding surface is deformed downwards, and the purpose of correcting the grinding surface is achieved.
Furthermore, the adjusting discs are multiple, the adjusting discs are divided into different sizes, and the large adjusting disc is installed outside the small adjusting disc.
As shown in fig. 1, in actual use of the polishing head, the polishing head often warps more near the edge, and thus a separate adjustment disc is required for adjustment.
Furthermore, the top disk 33 has a small screw hole 35 facing downward, and a small screw is installed in the small screw hole.
Thus, it is also possible to adjust the position of a circle on the polishing pad individually, as shown at C in fig. 2, so that a small screw can be screwed into this location and corrected against this location.
Furthermore, the top disc 33 is provided with a downward through hole, a small screw is arranged in the through hole, and the grinding surface 21 is provided with a grinding surface screw hole matched with the small screw.
By the arrangement, a small screw can be placed in the through hole, the lower surface of the small screw is matched with the screw hole in the grinding surface, the grinding surface can be pulled upwards, and the direction of the applied force is the direction of an arrow K in figure 1, so that the grinding surface is corrected.
Further, the polishing head also includes a plurality of pads. In this way, the pad can be placed at J in fig. 1, i.e. between the upper face of the abrasive disc and the top disc, and the correction of the abrasive face can be performed.
Further, the thickness of the gasket is not the same. This makes correction more convenient.
Further, the device also comprises one or more ejector rods 4 arranged between the screw hole and the top disc, and the middle of each ejector rod is provided with a stretching mechanism 41.
Thus, the pin can be positioned between the threaded hole and the top plate, and the pin generates a force as indicated by arrow H in FIG. 2 to correct the polishing surface. The stretching mechanism can be two sections of connected screws, can also be a stretching cylinder, can also be other parts, and only can stretch the two ends of the ejector rod.
The above description is only an embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications within the field of the present invention by those skilled in the art are covered within the scope of the present invention.
