Internal grinding machine

Abstract

The invention discloses an internal grinding machine. The internal grinding machine comprises a lathe body and a longitudinal workbench which is in sliding connection with the lathe body, wherein a transverse workbench is in sliding connection with the upper part of the longitudinal workbench; a transverse feeding mechanism is arranged on the transverse workbench; the transverse feeding mechanism is connected with a speed reducer; the speed reducer is connected with a feed control mechanism; the internal grinding machine further comprises a grating ruler; the main scale of the grating ruler is arranged on the transverse workbench in the feeding direction of the transverse workbench; a reading head of the grating ruler is arranged below the main scale; the reading head is electrically connected with a data display instrument. The internal grinding machine disclosed by the invention can change the feeding manner and the feed rate measuring manner, improves the stability of the workpiece size and the working accuracy, reduces misoperation frequency of the excessive feed rate, and decreases the rejection rate.

Description

technical field [0001] The invention relates to an internal grinding machine for processing the surface of an inner hole, in particular to a transverse feed system in the internal grinding machine. Background technique [0002] The internal grinding machine includes a bed, a spindle box, a longitudinal table, a horizontal table, and a grinding wheel frame on the horizontal table. The internal grinding machine is mainly used for grinding the surface of a cylindrical or conical inner hole. The internal grinding machine generally has Longitudinal and horizontal feeding, vertical feeding is generally completed by the longitudinal table, which can ensure the complete processing of long workpieces in the length direction; lateral feeding is completed by the horizontal table, which determines the amount of grinding and the accuracy of grinding. The grinding feed rate of the existing internal grinding machine is determined by the operator observing the scale of the mechanical handle...

AI Technical Summary

Problems solved by technology

The grinding feed rate of the existing internal grinding machine is determined by the operator observing the scale of the mechanical handle, which is prone to insufficient feed or excessive feed, especially when the feed is small, and the feed speed is too fast to exceed the feed rate. Quantity, resulting in large dimensional errors, and even waste products; troublesome operation, low precision, high requirements for workers' skills, the accuracy of workpiece processing largely depends on the technical level of workers, for micron-level feed The quantity is also completely dependent on the worker's estimation of the handle scale, which makes the production efficiency low and the workpiece size is unstable
