Active measuring device of end surface of CNC internal grinding machine

Abstract

The invention discloses an active measuring device of the end surface of a CNC internal grinding machine, comprising a machine tool chuck, a pressing cover, a regulating grinding head, a pneumatic micrometer, a positioning floral disc and a shaft coupler for coupling a head box of a machine tool. The end of the pressing cover with a milling flute is tightly matched with the positioning floral disc which is locked and fixed on an air pipe by a thread through hole on the pressing cover; the end of the pneumatic micrometer with the air pipe is inserted into a main shaft from one end of the machine tool chuck and is fixed on the shaft coupler on the end of the machine tool; three air hole branches on the other end of the air pipe are locked on the rest thread holes of the positioning floral disc and sealed by corresponding positioning bolts internally provided with ventilating holes; the regulating grinding head is positioned near the positioning floral disc; the air flow of the pneumatic micrometer is introduced by the shaft coupler with an air pipe connector and enters the space between the positioning floral disc and the pressing cover by the air pipe; the air flow is branched on the three air holes on the positioning floral disc by the air pipe and the blocked size of air flow quantity responds to the flopping size of a measured end surface. The active measuring device effectively enhances the labor efficiency and reduces the labor strength and the potential safety hazard.

Description

technical field [0001] The invention belongs to the technical field of numerical control internal grinding gear processing, and in particular relates to an active measuring device for end face positioning. Background technique [0002] CNC internal grinding machine is used to grind the inner hole of parts. Due to its advantages in processing accuracy and efficiency, CNC internal grinding machine has been widely used in production. Before starting to process the workpiece, the workpiece must first be placed on the machine tool Or occupying a certain correct position in the fixture, this process is called positioning; in the existing numerical control internal grinding technology, there is no fixture similar to the present invention that can effectively and quickly improve the positioning accuracy, and the existing technology Yes: Since there is no special device that can automatically ensure the runout of the end face of the workpiece after clamping, the method of calibrating...
