The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

An efficient and environment-friendly grinding machine, as shown in fig. 1 to 3, comprises a lower grinding disc 2 mounted on the upper side of a worktable 1, and an upper grinding disc 4 mounted on a frame 3 corresponding to the lower grinding disc; it should be noted that the frame may be installed on the workbench, or may be installed and fixed on the ground or other structural members, and may be arranged as close to the workbench as possible;

an enclosing structure 5 is arranged at the outer edge of the lower grinding disc, an operation area is formed on the inner side of the enclosing structure, and a ventilation cavity 6 is arranged on the workbench corresponding to the position below the operation area of the lower grinding disc; specifically, the enclosing structure can be formed by enclosing plates arranged around the upper side of the workbench, and when the air suction device works, certain negative pressure can be formed on the inner side of the arranged enclosing structure, so that abrasive dust can be conveniently sucked into the ventilation cavity and then enter the ventilation pipe to be filtered;

the upper surface of the lower grinding disc is provided with a plurality of workpiece fixing grooves 7 and a plurality of through holes 8, and the through holes are used for communicating the operation area with the ventilation cavity;

the workbench is provided with a ventilation pipe 9 communicated with the ventilation cavity, the ventilation pipe is detachably provided with a filtering assembly 10, and the tail end of the ventilation pipe is provided with an air suction device 11. The air suction device generally adopts a suction fan.

It should be noted that the drawings are only schematic structures, the enclosure does not need to be a circular operation area, the workbench does not need to be cylindrical, and other structural forms are possible as long as the problems to be solved by the invention can be realized and normal grinding production is not interfered. Generally, each through hole is uniformly distributed by taking the center of the workbench as the center, so that the uniformity of wind power is ensured as much as possible, and the negative pressure formed in an operation area is relatively stable.

In an alternative embodiment, the groove bottom of the workpiece fixing groove is provided with a communication hole, and the workpiece fixing groove is communicated with the ventilation cavity through the communication hole. The advantages of such a structural design are: firstly, when workpieces to be ground are not placed in some workpiece fixing grooves, under the condition that the air suction device is opened, the (communication holes of) the workpiece-free fixing grooves actually play a role similar to that of via holes, and the negative pressure environment of an operation area is ensured; secondly, when placing the work piece and grinding in the work piece fixed slot, under the condition that the device that induced drafts opened, can effectually produce certain adsorption to the work piece through the suction that the intercommunicating pore produced, make the work piece can not be easy break away from the work piece fixed slot.

The rack is provided with a sliding frame 12, the upper grinding disc is arranged on the sliding frame, the upper grinding disc is driven to rotate by a first driving mechanism 13 arranged on the sliding frame, and the sliding frame is driven to slide in the height direction of the rack by a second driving mechanism 14 arranged on the rack. Usually, first actuating mechanism adopts servo motor, and second actuating mechanism adopts electronic jar or pneumatic cylinder, and general second actuating mechanism can bilateral symmetry arrange two sets ofly, certainly, to first actuating mechanism setting position, specific structural arrangement forms such as second actuating mechanism setting position, the technical staff in the art can design according to actual need can, owing to rotate through the motor drive part, promote the category that the part slides for prior art can realize through electronic jar or pneumatic cylinder, consequently, no longer give consideration to here.

The upper grinding disc can be generally arranged on the sliding frame in a rotating mode, the first driving mechanism is fixed on the sliding frame, and the upper grinding disc is driven to rotate through the first driving mechanism; the sliding frame is driven to slide along the rack in the height direction through the telescopic action of the second driving mechanism, so that the upper grinding disc is close to or far away from the lower grinding disc. It should be pointed out that the frame can design the form of two guide posts for bilateral symmetry, and the gliding setting respectively in both ends about the carriage is on the guide post, through with guide post sliding fit, has guaranteed the accuracy of upper and lower abrasive disc location relation.

Be equipped with the sealing member between above-mentioned abrasive disc and the workstation down, avoid leaking into the air from the junction, and then guarantee that the operation district forms stable little negative pressure state.

The filter assembly comprises a fixed frame 15 and a filter element 16 inside the fixed frame. In an optional embodiment, the ventilation pipe is provided with a mounting frame matched with the fixing frame. Specifically, be equipped with the opening that filtering component (fixed frame) can insert on the installing frame, here structural design can be convenient the installation with dismantle filtering component.

Of course, the structure of the mounting part of the filtering component can also adopt a mounting structure similar to that of the filter element of the automobile air conditioner, and the structure of the mounting part can be realized only by conveniently dismounting the filtering component. After using a period, pull down filtering component, clear up or change the filter core to guarantee reliable adsorption effect, furthest reduces the powder and discharges outside polluted environment.

The filter screen part of the filter element adopts filter cotton or filter cloth, and actually, the filter screen in the filter element created by the invention can adopt an air filter screen in an air filter. Therefore, even if some powder such as abrasive dust enters the ventilation pipe, the powder is filtered and adsorbed by the filtering component, the environment pollution caused by the emission is avoided, and the environmental protection performance is good.
