Automatic bar grinding machine and charging assembly

Abstract

The invention provides an automatic bar grinding machine. The machine comprises a charging assembly for charging a bar, a rotating clamping mechanism for receiving the bar on the charging assembly, and a grinding mechanism for polishing and grinding the bar which is clamped on the rotating clamping mechanism, wherein the rotating clamping mechanism is capable of receiving the bar on the charging assembly and conveying the received bar to a grinding station of the grinding mechanism. The grinding mechanism is capable of roughly processing the bar.

Description

technical field [0001] The invention relates to the field of processing bar parts, in particular to an automatic bar grinding machine and a feeding assembly for feeding the grinding machine. Background technique [0002] Shaft (bar stock) parts are one of the typical parts often encountered in hardware accessories. It is mainly used to support transmission parts, transmit torque and bear load. According to the different structural forms of shaft parts, it can generally be divided into optical shaft, There are three types of stepped shafts and special-shaped shafts; or divided into solid shafts, hollow shafts, etc. They are used in machines to support transmission parts such as gears and pulleys to transmit torque or motion. Shaft parts are rotating parts whose length is greater than the diameter. Generally, they are composed of outer cylindrical surfaces, conical surfaces, inner holes and Composed of threads and corresponding end faces, according to different structural sha...

They are used in machines to support transmission parts such as gears and pulleys to transmit torque or motion. Shaft parts are rotating parts whose length is greater than the diameter. Generally, they are composed of outer cylindrical surfaces, conical surfaces, inner holes and Composed of threads and corresponding end faces, according to different structural shapes, shaft parts can be divided into optical shafts, stepped shafts, hollow shafts and crankshafts, etc. The processing and polishing of shaft parts need to be completed by corresponding numerical control equipment. The curved surface of shaft parts is a cylindrical surface, which makes the grinding process complicated. Usually, the machining accuracy of traditional CNC machine tools is not easy to guarantee. When grinding, it needs to rely on manual proficiency and control the grinding allowance, so the machining accuracy is not high, and the production efficiency is reduced.
