Description

Technical Field

The present application relates to the field of the mechanical grinding machine, and specifically to a multi-purpose grinding disc.

Background Arts

The market for the engineering field is very large. Various machines are often used, especially in the field of the grinding machine, various mechanical parts or some decorated walls are often polished. However, grinding discs are often used in the field of the grinding machine. The existing grinding discs only have a single function, and there is no way to adjust the angle of those grinding disc. For tiny positions, people have to directly polish tiny positions by hands, resulting in much inconvenience.
Aiming at the problem of a single use function and an inability of adjusting the angle of the grinding disc by the existing grinding machine, no effective solution has been proposed so far.

Summary of the Utility Model

The main purpose of this application is to provide a multi-purpose grinding disc to solve the technical problem of a single use function in the grinding disc and an inability of adjusting its angle.
In order to achieve the above purpose, according to one aspect of the present application, a multi-purpose grinding disc is provided, which comprises an angle adjusting device and a connecting device connected to a grinding machine. An upper end of the angle adjusting device is equipped with a connecting kit that matches the connecting device, and the angle adjusting device is connected to the connecting device through the connecting kit. The angle adjusting device mainly serves the purpose of rotating at multiple angles, and solves the technical problem that the grinding disc of the grinding machine cannot adjust the angle. One end of the connecting device is connected to the grinding machine, and the other end of the connecting device is connected to the connecting kit that is located in the angle adjusting device and matches the connecting device.
A lower part of the angle adjusting device is provided with a fixing piece for fixing the angle adjusting device, an adhesive device is provided under the fixing piece, and the adhesive device is adhered to the fixing piece. An abrasive paper for dull polish is installed below the adhesive device.
Further, the angle adjusting device is a rubber sleeve.
Further, the angle adjusting device is gourd-shaped, and it is configured to have a small upper part and a large lower part.
Further, a distance between the center of the cross-sectional of the upper end of the connecting device and a peripheral edge of the cross-section is not equal. It mainly functions to facilitate the disassembly. When there is a need to polish small parts by hands, pliers, wrenches and other tools are used to perform the disassembling work. Since the existing device generally is circular in the prior art, it is very inconvenient to carry out the disassembling work, and skidding easily occurs.
Further, the connecting kit is an insert nut, and the lower end of the connecting device is provided with a thread that matches the connecting kit. The insert nut has a very wide range of functions. The contact between the connecting kit and the connecting device becomes tighter and tighter during the grinding process with the use of the insert nut, and no looseness occurs.
Further, the fixing piece is circular, and the center of the fixing piece is provided with a through hole.
Further, the adhesive device is a Velcro.
Further, the angle adjusting device is provided with an antiskid part around the circumference of the angle adjusting device.
Further, the antiskid part comprises, but is not limited to, a sawtooth antiskid pattern, a spiral antiskid pattern and a polygonal antiskid pattern. The antiskid pattern mainly plays a role of antiskid. When the connecting device is disassembled and a polishing process is carried out by hands, the antiskid pattern can play a better antiskid effect.
Regarding the utility model of this application, the angle adjusting device is adopted, the connecting device and the angle adjusting device are combined, and the connecting device and the angle adjusting device can be detached, so as to provide a grinding disc with multiple functions and an adjustable angle just for generating the technical effects of realizing the adjustment of the angle of the grinding disc angle, a hand-operated grinding disc and a dual use of the grinding machine. Further, the technical problem of a single use function in the grinding disc and the inability of adjusting the angle can be solved.

The multi-purpose grinding disc comprises an angle adjusting device 3 and a connecting device 1 connected to a grinding machine. An upper end of the angle adjusting device 3 is equipped with a connecting kit 2 that matches the connecting device 1, and the angle adjusting device 3 is connected to the connecting device 1 through the connecting kit 2. The angle adjusting device 3 mainly serves the purpose of rotating at multiple angles, and solves the technical problem that the grinding disc of the grinding machine cannot adjust the angle. One end of the connecting device 1 is connected to the grinding machine, and the other end of the connecting device 1 is connected to the connecting kit 2 that is located in the angle adjusting device 3 and matches the connecting device 1.
As shown in Figures 1-4, the lower part of the angle adjusting device 3 is provided with a fixing piece 4 for fixing the angle adjusting device 3, and an adhesive device 5 is provided under the fixing piece 4, and the adhesive device 5 is bonded to the fixing piece 4; an abrasive paper 6 for dull polish is installed below the adhesive device 5. The angle adjusting device 3 is a rubber sleeve. The angle adjusting device 3 is gourd-shaped, and is configured to have a small upper part and a large lower part.
As shown in Figures 1-4, the upper part of the connecting device 1 is cylindrical, and the upper end of the connecting device 1 is in the shape of a flat-blade screwdriver. It mainly functions to facilitate the disassembly. When there is a need to polish small parts by hands, pliers, wrenches and other tools are used to carry out the disassembling work. Since the existing device generally is circular in the prior art, it is very inconvenient to carry out the disassembling work, and skidding easily occurs. The connecting device 1 is made of a metallic material.
As shown in Figures 1-4, the connecting kit 2 is an insert nut, and the lower end of the connecting device 1 is provided with a thread that matches the connecting kit 2. The insert nut has a very wide range of functions. the contact between the connecting kit 2 and the connecting device 1 becomes tighter and tighter during the grinding process with the use of the insert nut, and no looseness occurs.

As shown in Figures 1-4, the angle adjusting device 3 is provided with an antiskid part 7 around the circumference of the angle adjusting device 3. The antiskid part 7 has a spiral antiskid pattern. The antiskid pattern mainly plays a role of antiskid. When the connecting device 1 is disassembled, and a polishing process is carried out by hands, the antiskid pattern can play a better antiskid effect.
In the embodiment of this application, the driving cavity of the grinding machine is connected to the connecting part of the grinding disc, the insert nut is tightly connected to the rubber sleeve, and the galvanized iron sheet presses the rubber sleeve. One surface of the Velcro is glued to the galvanized iron sheet with glues, and the other surface of the Vecro is pasted to an abrasive paper 6. When the abrasive paper 6 needs to be replaced, it is just torn off. When there is no need to use the grinding machine, the connecting device 1 is disassembled just through use of the pliers and other tools. Then, people hold the grinding disc to carry out the grinding process, which is very convenient. The angle adjusting device 3 is adopted, the connecting device 1 and the angle adjusting device 3 are combined together, and the connecting device 1 and the angle adjusting device 3 can be detached, so as to provide a grinding disc with multiple functions and an adjustable angle just for generating the technical effects of realizing the adjustment of the angle of the grinding disc, a hand-operated grinding disc and a dual use of the grinding machine. Further, the technical problem of a single use function in the grinding disc and the inability of adjusting the angle can be solved.
The foregoing descriptions are only preferred embodiments of the application, and are not intended to limit the application. For those skilled in the art, the application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
