Four-axis linkage lifting type numerical control end face tool sharpener

Abstract

The invention discloses a four-axis linkage lifting type numerical control end face tool sharpener. The four-axis linkage lifting type numerical control end face tool sharpener comprises a rack, an inclined rail tool rest and a spindle box, and the inclined rail tool rest comprises an inclined rail tool rest base, an X-axis lead screw, a middle carriage and an X-axis servo motor. When the X-axis servo motor is controlled to rotate, the middle carriage is driven to move left and right. The inclined rail tool rest further comprises a lifting sliding plate, a lifting seat, a Y-axis servo motor, a rotating shaft and a tool hanging plate. When the Y-axis servo motor is controlled to operate, the lifting sliding plate is driven to ascend and descend. The rotating shaft is rotationally mounted on the lifting sliding plate. The spindle box comprises a spindle box supporting seat, a spindle mounting seat, a Z-axis screw rod, a Z-axis servo motor and a spindle, and when the Z-axis servo motor is started, the spindle mounting seat can move back and forth through nut transmission of the Z-axis screw rod, so that a grinding wheel moves back and forth. A swing shaft (A shaft) of a knife rest structure adopts a high-precision RV speed reducer structure, so that the precision of the swing angle is improved, and the whole structure is simple and durable.

Description

technical field [0001] The invention relates to a four-axis linkage lifting type numerical control end face knife grinder, which belongs to the technical field of knife grinders. Background technique [0002] The end face sharpener is made of high-quality carbon structural steel, the tool holder adopts a 30° angle inclined rail structure, and the transmission mode of the grinding head is a rolling linear guide rail; the cooling water is directly sprayed to the position to be processed by the water pipe in the grinding wheel cover. Make the cooling effect better; each axis of the whole machine is controlled by absolute value servo motor, and the speed can be adjusted arbitrarily within the specified range. The grinding wheel is automatically fed to sharpen the knife, and the grinding head adopts a cylindrical grinding wheel, which increases the service life of the grinding wheel by 1 / 3, greatly reduces the cost of sharpening the knife, and the front and rear movement of the g...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a four-axis linkage lifting type CNC end face grinder, which solves the problem that the structure of the CNC end face grinder currently on the market generally adopts a square casting guide rail. It is an improvement on the basis of the original hydraulic machine, the operation accuracy is not high, and the response speed is slow, and it cannot meet the technical problems of CNC high-precision operation.
