Rotatable workpiece clamping mechanism for automatic cutter grinding machine

Abstract

The invention discloses a rotatable workpiece clamping mechanism for an automatic cutter grinding machine. The mechanism comprises a base body and a motor, wherein the motor is mounted on the base body; the base body has a mounting through hole; a rotating shaft is pivoted and mounted in a mounting through hole; a mounting disc is fixed at the front end of the rotating shaft; the rotating shaft and the mounting disc have communicated inner holes; a center pull rod is movably mounted in the inner hole of the rotating shaft; the front end of the center pull rod is connected with a clamping head part; the back end of the center pull rod is connected with a piston of the cylinder; the clamping head part is movably mounted in the inner hole of the mounting disc; the inner wall of the rotating shaft has an inclined surface; the outer wall of the clamping head part has an inclined taper surface fitting an inclined surface; a center hole for placing a workpiece is formed in the clamping head part; and the rotating shaft is driven by the motor. The mechanism can improve the claming precision of a cutter required to be sharpened, and further can the cutter sharpening precision.

Description

Technical field: [0001] The invention relates to the technical field of tool grinding machines, in particular to a rotatable workpiece clamping mechanism for automatic tool grinding machines. Background technique: [0002] In the field of mechanical processing, especially in the process of cutting or drilling, when the cutting or drilling tool is worn, it is necessary to sharpen the tool. Grinding on a rotating grinding wheel makes the knife have a sharp edge. This is a sharpening method that depends on the personal skills of the operator. The quality of the sharpening is unstable, and the efficiency of this sharpening method is relatively low. Now there are many fields that use CNC The biggest feature of CNC tool grinding is high grinding efficiency. However, the clamping of the tool in the existing CNC tool grinder is a one-time fixed clamping, that is, the tool that needs to be ground is directly clamped.

[0002] In the field of mechanical processing, especially in the process of cutting or drilling, when the cutting or drilling tool is worn, it is necessary to sharpen the tool. Grinding on a rotating grinding wheel makes the knife have a sharp edge. This is a sharpening method that depends on the personal skills of the operator. The quality of the sharpening is unstable, and the efficiency of this sharpening method is relatively low. Now there are many fields that use CNC The biggest feature of CNC tool grinding is high grinding efficiency. However, the clamping of the tool in the existing CNC tool grinder is a one-time fixed clamping, that is, the tool that needs to be ground is directly clamped. Fix it on the clamping head of the tool, and then perform the tool setting on the clamped tool that needs to be ground. Since the one-time fixed clamping is only one point when you set the tool, it cannot be rotated. Generally, the clamping accuracy is not high, and sometimes there will be deviations in the clamping, so this will seriously affect the accuracy of tool grinding, and in severe cases, the tool may be scrapped.
