Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of low automation and low batch production efficiency of the existing grinding machine in the cylindrical grinding process, and the existence of accurate positioning devices for the cylindrical grinding of YAG single crystal fine cylinders with small workpieces. It is difficult to clamp, which will easily lead to the breakage of the processed workpiece, and it is difficult to obtain better surface integrity of such hard and brittle materials, so as to provide a fully automatic feeding device for hard and brittle single crystal micro-cylindrical external cylindrical ultrasonic-assisted grinding machines

Abstract

The invention discloses a full-automatic feeding device of a hard and brittle single crystal micro-cylinder outer circle ultrasonic auxiliary grinding machine, and relates to the field of mechanical equipment. The full-automatic feeding device solves the problems that an existing grinding machine is low in automation degree and batch production working efficiency during outer circle grinding machining, and when a YAG single crystal micro-cylinder outer circle with the small workpiece size is ground, accurate positioning and clamping are difficult, a machined workpiece is prone to being broken,and the good surface integrity of the hard and brittle material is difficult to obtain. A hopper device is arranged above a material vibrating disc; a discharging opening of the hopper device is right opposite to the material vibrating disc; the material vibrating disc is arranged on a material vibrating disc support; an outlet of the material vibrating disc is connected with a workpiece separating mechanism; a first photoelectric sensor is fixedly arranged on the left side of the workpiece separating mechanism; a feeding mechanism is arranged above the right portion of the workpiece separating mechanism; and an ultrasonic oval vibration auxiliary grinding device is arranged right in front of the workpiece separating mechanism. The full-automatic feeding device is used for automatic transmission and automatic clamping of hard and brittle single crystal micro-cylinder outer circle grinding.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a fully automatic feeding device for a hard and brittle single crystal micro-cylindrical outer circle ultrasonically assisted grinding machine. Background technique [0002] In recent years, with the rapid development of new materials and new processes, some typical hard and brittle materials such as yttrium aluminum garnet crystal (YAG) and sesquioxide LU2O3 have high optical uniformity, good spectral characteristics, good Optical transmittance, excellent thermomechanical properties, and stable physical and chemical properties occupy an extremely important position in the fields of aerospace, national defense and military, and industrial production, and its application range is constantly expanding. However, due to the high hardness, high brittleness, and low fracture toughness of these materials, machining defects such as surface / subsurface cracks and surface pits are prone ...
