Intelligent machining equipment for ends of silicon carbide ceramic roller bars and roller bar machining process

Abstract

The invention discloses intelligent machining equipment for the ends of silicon carbide ceramic roller bars and a roller bar machining process, and belongs to the technical field of new material machining equipment. According to the technical scheme, the intelligent machining equipment is characterized by comprising a rack, wherein a shell is integrally formed at the top of the rack; a placement disc is arranged at the center of the top of the rack, and annularly-distributed through holes are formed in the bottom of the placement disc; a hollow pipe is fixedly connected to the top of the inner wall of the shell, a positioning disc fixed to the inner wall of the shell is arranged at the upper end of the surface of the hollow pipe, first air cylinders are arranged at the top of the positioning disc, annularly-distributed pressing rods are arranged at the bottoms of the first air cylinders through a pressing plate, and the bottom ends of the pressing rods right face the circle centers of the through holes; and a liftable material placement device is arranged on the inner wall of the rack and used for placing the roller bars, and the roller bars can penetrate through the through holes and extend into a grinding groove through lifting of the material placement device. The intelligent machining equipment reduces the damage of clamping to the ends of the silicon carbide ceramic roller bars, and is higher in grinding efficiency and better in grinding effect.

Description

technical field [0001] The invention relates to the technical field of new material processing equipment, and more specifically relates to an intelligent processing equipment for the end of a silicon carbide ceramic roller rod and a processing technology for the roller rod. Background technique [0002] Silicon carbide ceramics not only have excellent mechanical properties at room temperature, such as high flexural strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance properties, etc.) is the best known ceramic material. The high temperature strength of hot pressing sintering, pressureless sintering and hot isostatic pressing sintering can be maintained up to 1600°C, which is the best high temperature strength among ceramic materials. Oxidation resistance is also the best among all non-oxide ceramics. Alias ​​emery. [0003] With th...

AI Technical Summary

Problems solved by technology

[0003] With the development of silicon carbide ceramic materials, the application of silicon carbide ceramic roller rods is gradually increasing. When grinding the ends of silicon carbide ceramic roller rods, the rod body needs to be fixed by a clamping mechanism, and then the end is manually aligned. Grinding the head, but when clamping, the clamping force is difficult to control, which is easy to cause damage to the end, and manual grinding is prone to uneven grinding. We propose an intelligent processing equipment for the end of silicon carbide ceramic roller rods.
