A grinding device with manual and automatic dual-mode free switching

Abstract

The invention relates to the related field of machine grinding devices, and discloses a manual and automatic double-mode free-switching grinding device, which includes a grinding box, a processing chamber with an opening forward, and a numerically controlled movement fixedly connected to the right end wall of the processing chamber. Fixture, the upper end surface of the CNC movable fixture is fixedly connected with the main box, and the main box is provided with a spherical cavity opening to the right. When manual grinding is required in the automatic processing process, the withdrawal of the movable sphere is canceled by restricting the retraction of the slider. Fixed, by turning the clamping knob, the lateral limiting block is out of contact with the lateral slider. At this time, the operator can freely operate the workpiece to move or rotate, so that the workpiece can be polished automatically or manually in one clamping. , when it is necessary to continue automatic grinding after manual grinding, the alignment slide block slides to the left to convert the alignment spring into a stretched state, so that the movable sphere and the movable connection block are quickly reset.

Description

technical field [0001] The invention relates to the related field of machine grinding devices, in particular to a manual-automatic dual-mode free-switching grinding device. Background technique [0002] At present, the grinding work of workpieces with complex shapes is mainly carried out by manually holding the workpiece close to the friction wheel. The operation is cumbersome and the efficiency is not high. The use of CNC movable fixtures can greatly improve the efficiency of grinding work. CNC movable fixtures with simple displacement and rotation functions are difficult to deal with workpieces with complex shapes, and usually require manual supplementary grinding. Some workpieces need to be automatically ground after manual grinding in order to improve efficiency. During the period, the workpiece needs to be disassembled and clamped several times. It reduces the work efficiency, and also affects the grinding accuracy of the workpiece. SUMMARY OF THE INVENTION [0003] ...
