Description

TECHNICAL FIELD

[0001] The application relates to the technical field of grinding machine equipment, in particular to a grinding machine dust cover clamping device. BACKGROUND

[0002] The lower end of the grinding machine needs to be provided with a dust cover to prevent dust from flying during grinding, and the dust cover is also convenient for adsorbing and collecting dust. Since the dust cover is a consumable, it is usually installed on the lower end of the grinding machine in a clamping manner, so as to facilitate replacement. The conventional dust cover of the grinding machine is made of dustproof rubber strips which are wrapped around the gear box cover and are adhered and connected by male and female buckles after being pulled tight. In the state of replacing the grinding material of the grinding head of the machine, the dustproof rubber strips are prone to falling off, and need to be repeatedly installed during use, thereby increasing the labor of workers. SUMMARY

[0003] The application aims to solve the technical problems in the above background, and provides a grinding machine dust cover clamping device. The application can quickly clamp the dust cover to prevent replacement.

[0004] To achieve the above technical purposes, the technical scheme adopted by the application is as follows:

Preferably, the number of the first screw holes is four. The air spring 20 is used for providing a pulling force to the pressing plate connecting seat 40, so that the pressing plate 10 can be pulled back to be close to the dust cover 200 after being lifted by the air spring 20, thereby playing a clamping role on the dust cover 200. One end of the air spring 20 is rotationally connected with the pressing plate connecting seat 40, and the other end of the air spring 20 is rotationally connected with the grinding machine 100. The turnover base 30 is fixedly connected with the grinding machine 100, and the turnover base 30 is rotationally connected with the pressing plate connecting seat 40, that is, the pressing plate connecting seat 40 can rotate on the turnover base 30, so as to drive the pressing plate 10 to press the dust cover 200 downward.

[0024] The original buckle type fixing dust cover is changed into a pressing plate type in the application. Through the pushing force of the air spring 20, the pressing plate connecting seat 40 can be automatically pushed forward and rotated on the turnover base 30, so as to drive the pressing plate 10 to press the dust cover 200. Even if the grinding head (abrasive material) needs to be replaced, the dust cover 200 will not fall off, and the efficiency of replacing the grinding head is improved.

[0025] As a preferred embodiment of the application, a mounting groove 13 is arranged on the pressing plate body 11. A step is formed between the mounting groove 13 and the pressing plate body 11. A handle 14 is mounted on the mounting groove 13. Specifically, the handle 14 can be fixed on the step through screws. The mounted handle 14 facilitates pulling the pressing plate 10. Preferably, a pulling edge 16 is arranged on the handle 14, and a through groove 15 is arranged above the pulling edge 16. The pulling edge 16 facilitates a user to hold the handle 14.

[0026] As a preferred embodiment of the present application, one end of the gas spring 20 is rotatably connected to the first universal shaft 21 and the pressing plate connecting seat 40. Specifically, the rotating connecting part 41 is provided with a second threaded hole 43, the second threaded hole 43 is threadedly connected with one end of a bolt (not marked in the figure), and the other end of the bolt is connected with the first universal shaft 21, that is, the first universal shaft 21 is fastened on the rotating connecting part 41 by the bolt, and can rotate with the rotating connecting part 41. Similarly, the other end of the gas spring 20 is rotatably connected to the second universal shaft 22 and the grinding machine 100, and the second universal shaft 22 is also fastened on the grinding machine 100 by a bolt, and can rotate with the grinding machine 100. In order to increase the stability of the present application, two gas springs 20 are provided, and the two gas springs 20 are arranged on the two sides of the rotating connecting part 41. Preferably, an included angle α is formed between the gas spring 20 and the grinding machine 100, the included angle α is 3-6°, and preferably 5°. The angle is arranged to enable the thrust of the gas spring 20 to drive the pressing plate connecting seat 40 to rotate.

[0027] As a preferred embodiment of the present application, the side of the pressing plate connecting seat 40 is in an L-shaped structure, and the side of the pressing plate 10 is in an inverted L-shaped structure. The L-shaped structure and the inverted L-shaped structure are buckled with each other, that is, the pressing plate connecting part 12 and the fixed connecting part 42 are attached to each other, so that the connection between the pressing plate 10 and the pressing plate connecting seat 40 is more stable. The pressing plate connecting seat 40 is also provided with a notch 45, which is matched with the turnover base 30, that is, the turnover base 30 is arranged in the middle of the pressing plate connecting seat 40 through the notch 45. In order to fix the turnover base 30, at least two second through holes are arranged on the turnover base 30 from top to bottom, preferably, the number of the second through holes is four, and the turnover base 30 is connected with the grinding machine through the bolt screwed into the second through hole.
