The invention belongs to the technical field of grinding knife machine tools and particularly relates to a five-axis linkage numerical control grinding knife machine tool. The five-axis linkage numerical control grinding knife machine tool comprises a rack, and the rack is provided with a workbench and a main shaft table, wherein the movement directions of the workbench and the main shaft table are perpendicular to each other; the main shaft table is provided with a steering device, the steering device comprises a index plate, the index plate is internally provided with a steering shaft, the axis of the steering shaft and the axis of a workpiece shaft are perpendicular to each other and are arranged on the same horizontal face, the front end of the steering shaft is fixedly provided with a steering plate, and the steering plate is rotatably arranged on the front end portion of the index plate; the steering plate is provided with a lifting device, the lifting device comprises a lifting table, the lifting table is provided with a main shaft drive device, the main shaft drive device comprises a main shaft, the end portion of the main shaft is provided with a grinding wheel, and the axis of the main shaft and the axis of the steering shaft are perpendicular to each other; and the axis of the steering shaft and the work face of the grinding wheel are jointly arranged in the same plane. By means of the five-axis linkage numerical control grinding knife machine tool, woodworking tool cutters, valve cutters, threading dies, screw taps and other cutters with complex knife edge shapes can be machined automatically.

Description

technical field [0001] The invention belongs to the technical field of knife sharpening machine tools, in particular to a five-axis linkage numerically controlled knife sharpening machine tool. Background technique [0002] At present, for tools with complex and changeable blade shapes and sizes, such as woodworking knives, manual low-speed grinding can only be generally used. Traditional sharpening machines are divided into grinding stones and grinders: [0003] The use of the grinding stone is entirely by hand, which is not only inefficient, but also consumes a lot of physical strength. In addition, due to the different materials and particle sizes of the whetstones, they may not necessarily match the knives to be sharpened, so it is difficult to ensure the quality of the sharpening, and the consistency of the sharpened knives is poor. [0004] There are two types of grinders: one is the hand grinder. When working, one hand shakes the grinder while the other sharpens the...

Problems solved by technology

[0003] The use of grinding stones is entirely manual, which is not only inefficient, but also consumes a lot of physical strength

In addition, due to the different materials and particle sizes of the whetstones, they do not necessarily match the knives to be sharpened, so it is difficult to ensure the quality of the sharpening, and the consistency of the knives after grinding is poor.

[0004] There are two types of grinders: one is the hand grinder. When working, one hand shakes the grinder while the other sharpens the tool. It is difficult to coordinate the movements and the quality of sharpening is difficult to guarantee. It is difficult to adapt to different shapes with the above hand grinder. Tool processing, low processing efficiency, poor consistency of the tool blade after grinding, poor tool strength and short service life

In addition, the above-mentioned hand grinder is poorly equipped, which poses safety hazards to operators and is labor-intensive, resulting in high labor costs for enterprises.

[0005] The other is the electric grinder, the grinding wheel rotates at high speed, and the operator holds the blade close to the grinding wheel for grinding, which poses a safety hazard to the operator and is labor-intensive, and it is difficult to form a sharp cutting edge

[0006] In addition, for the wavy blade, its characteristic is that the relief angle is basically unchanged, but the position of the relief angle changes with the shape of the blade. The current machine cannot meet the corresponding changes in the position of the grinding wheel and the position of the relief angle of the sharpener. Therefore, it can only be done manually, so that the quality of the knife blade is uneven, and the efficiency is extremely low
