Automatic grinding device and grinding method of ceramic inserting core inner hole

Abstract

The invention discloses an automatic grinding device and a grinding method of a ceramic inserting core inner hole. The device comprises a programmable logic controller (PLC) controller, a drive device, a headstock portion, a left steel wire tensioning device, a right steel wire tensioning device and the like, wherein the drive device, the headstock portion, the left steel wire tensioning device, the right steel wire tensioning device are respectively connected with the PLC controller. The PLC controller is connected with a touch screen through a data line. The automatic grinding device and the grinding method of the ceramic inserting core inner hole has the advantages that an electro-magnetic induction switch which is high in 'sensitivity' can be used for controlling the upper limit of 'a grinding force' so that grinding tools (steel wires) can be ensured not to be snapped; meanwhile, 'a breaking line protective device' is also installed on the device to be ensured to be arranged on the safe side; various machining technological process and parameters are installed, the device can be solidified and preferably displaced at any time; the quality of processing products is reliable and the device is controllable; dispersion degrees of he size precision of a circular hole can be narrowed and a geometrical shape of the device can be guaranteed; a PLC program can be used for controlling the device and the stability of the product quality can be improved through process solidification; a 'touch screen' operating interface can be used for enabling the device to be audio-visual and more humanized; one operator can operate multiple machines.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an automatic grinding device and grinding method for the inner hole of a ceramic ferrule. Background technique [0002] In optical communication products, the processing accuracy of ceramic ferrule products is very high, such as the concentricity of the inner hole (with the outer circle) of the ferrule is 0.001mm, and the finish is 0.2um. Therefore, under this high-precision requirement, and the ceramic material In the case of difficult processing, grinding is often used for processing. However, the existing grinding methods mainly rely on manual grinding, and the specific grinding methods are as follows: [0003] The ceramic ferrule blank (that is, the workpiece) is clamped on the rotating device, and the steel wire is penetrated into the blank pre-hole (one end of the steel wire is corroded into a small size, the middle is a section of taper, and the other end is...
