Five-axis linkage numerical control grinding device of nonstandard grinding cutter and blade

Abstract

The invention discloses a five-axis linkage numerical control grinding device of a nonstandard grinding cutter and a blade. The five-axis linkage numerical control grinding device comprises a lathe bed, wherein a workbench, a first direct acting rail member, a second direct acting rail member, a third direct acting rail member, a rotary table transmission mechanism and a CNC control system are correspondingly arranged on the lathe bed, a rotary table is correspondingly arranged on the surface of the workbench, a to-be-ground workpiece is clamped on the rotary table by virtue of a workpiece holder, the third direct acting rail member is arranged on one side of the workbench by virtue of an upright post, the third direct acting rail member comprises a third direct acting block and a third direct acting rail, the rotary table transmission mechanism is arranged on the third direct acting rail member by virtue of a rotary table connecting plate, and a main shaft cutter is correspondingly arranged on the rotary table transmission mechanism on one side of the workbench. According to the five-axis linkage numerical control grinding device, the grinding efficiency and the grinding accuracyare increased, the self security of operating personnel is protected, the environmental pollution is reduced, the production in an automatic grinding mode is realized, and the manual complex operationis reduced.

Description

technical field [0001] The invention relates to a five-axis linkage numerical control grinding device for grinding non-standard cutting tools and blades. Background technique [0002] With the rapid development of the information age, the manual profiling sharpening machine (hereinafter referred to as "profiling grinding") currently used in the woodworking tool industry has the following working principles: to control the running track of the tool or workpiece according to the template or model Ordinary machine tools for grinding, the profiling grinder needs to manually change the angle of the grinding wheel many times to grind the tool and blade so that the grinding accuracy and smoothness between the cutting edge and the cutting edge of the cutting tool and blade to be ground are poor / Low service life. [0003] And the degrees of the axial relief angle and radial relief angle of the blade to be ground cannot accurately meet the required requirements, so that the required...

Problems solved by technology

[0002] With the rapid development of the information age, the manual profiling sharpening machine (hereinafter referred to as "profiling grinding") currently used in the woodworking tool industry has the following working principles: to control the running track of the tool or workpiece according to the template or model Ordinary machine tools for grinding, the profiling grinder needs to manually change the angle of the grinding wheel many times to grind the tool and blade so that the grinding accuracy and smoothness between the cutting edge and the cutting edge of the cutting tool and blade to be ground are poor / low service life

[0003] And the degrees of the axial relief angle and radial relief angle of the blade to be ground cannot accurately meet the required requirements, so that the required processing products and materials have relative process angles and cannot be achieved, which greatly reduces the cutting tool Persistence, increasing the cost of consumables

[0004] The profiling grinder cannot achieve fully enclosed protection, the grinding environment is poor, and a large amount of water mist will be mixed with the blade powder and scattered around the operator during the grinding process of the grinding wheel on the blade, which will not only cause irreparable serious damage to the human body but also cause serious damage to the human body. Pollution to the environment, low grinding efficiency of manual profiling knife sharpening machine tools, the same product requires multiple clamping, which not only affects the efficiency but also affects the grinding accuracy, and poses hidden dangers to the safety of the operators

[0005] The profiling mill uses an ordinary frequency conversion motor to drive the spindle head. The torque of the frequency conversion motor is low. The motor will be burned out, and the variable frequency motor needs to be replaced, which will lead to low grinding efficiency and high failure rate, and many other problems
