Description

Technical Field

[0001] The utility model relates to the technical field of cutting and grinding machines, in particular to a multifunctional cutting and grinding machine. Background Art

[0002] A cutting grinder is a device used to process the surface of materials, mainly used for precise processing of hard materials. Its working principle is to cut and grind the surface of materials through high-speed rotating cutting blades or grinding stones to achieve the purpose of fine processing. This machine combines cutting and grinding, which can effectively improve processing efficiency and processing quality. In cutting mode, the cutting grinder uses rotating blades to quickly cut or cut materials along the surface of the material to achieve a specific size and shape. In grinding mode, the surface of the material is ground with a grinding stone or grinding wheel to make the surface smoother and with higher precision. This machine is often used in industrial fields such as metal processing and glass processing. It can achieve high-precision and high-efficiency processing and is widely used in manufacturing and engineering fields.

[0003] When cutting and grinding wood or metal materials, a large amount of dust is usually generated. This dust will spread into the surrounding air. Although workers will wear protective tools such as masks, the high concentration of dust in the air will still affect the safety of workers. Utility Model Content

The motor drives the fixing rod to rotate through the transmission structure, and the fixing rod drives the grinding disc and cutting blade to rotate. The rotating grinding disc and cutting blade are then used by the operator to cut and grind the material.

[0008] Preferably, the two sides of the shell are connected, and a grid frame is installed on the side of the shell away from the filter screen. Air can circulate inside the shell, and the grid frame prevents large foreign objects from entering the shell.

[0009] Preferably, the fixing frame below the housing has fixing grooves on both sides, and fixing blocks are installed on both sides of the collecting drawer, with the two fixing blocks inserted into the two fixing grooves. The collecting drawer is movably connected to the fixing frame via the fixing blocks and the fixing grooves, so that some falling debris can fall into the collecting drawer, which collects the debris.

[0010] Preferably, the bottom of the fixing frame below the collecting drawer is provided with casters in a rectangular array, and the fixing frame is moved on the ground by the casters.

[0011] Preferably, a handwheel is mounted on the top of the screw, a bearing 3 is mounted on the top of the connecting plate, the bottom of the screw is fixedly connected to the inner ring of the bearing 3, and suction cups are mounted on the bottom of the connecting plate in a straight line and equidistantly. The handwheel can be used to rotate the screw, which is movably connected to the connecting plate through the bearing 3. When the screw is raised or lowered, it can drive the connecting plate to move up and down, and the connecting plate drives the suction cup to move up and down.

[0012] Preferably, a movable rod is installed on the top of the connecting plate, and a movable hole is opened on the fixed plate, and the top of the movable rod passes through the movable hole. The movable rod limits the connecting plate, and when the connecting plate is raised or lowered, the movable rod moves in the movable hole to prevent the connecting plate from shaking.
