Numerical control bearing ring turning automatic line

Abstract

The invention relates to a numerical control (NC) bearing ring turning automatic line. The automatic line comprises a feeding machine, a discharging machine, an automatic control online system and at least three NC lathes, wherein the automatic control online system respectively controls the feeding machine, the discharging machine and the NC lathes to work automatically; a connection material channel is arranged between each two adjacent NC lathes; and an automatic detection device is arranged inside the connection material channel and is used for detecting whether a machined bearing ring meets the standards. The automatic line mainly comprises two parts, namely the NC lathes and the automatic control online system, controls the NC lathes, the feeding machine, the discharging machine and other bearing ring conveying and machining devices to perform automatic efficient precision machining on the bearing ring by the automatic control online system, controls the turning state by the NC systems of the NC lathes, and implements the fully-automatic digital machining of a workpiece by the actions of feeding and discharging manipulators, so as to change the 'multiple persons one machine' and 'one person one machine' operation mode of an ordinary NC lathe, and realize a 'one person multiple machines' fully-automatic operation mode.

Description

technical field [0001] The invention relates to a numerically controlled turning processing production line, in particular to a numerically controlled bearing ring turning production line for processing medium and large bearing rings. Background technique [0002] Turning is one of the important components of metal cutting. It is the most widely used in the machinery manufacturing industry and occupies a very prominent position. At present, in the turning process of large-scale bearing rings in my country, single-tool machining is still used for processing. Medium and small bearing rings have gotten rid of single-tool machining. Most of the forgings are processed by multi-tool semi-automatic and fully automatic lathes. Turning can realize one-time processing of different parts of the same forging, but if there are many processing parts of the forging, and one lathe cannot realize the overall processing of the forging, multiple lathes are required to process different parts of...

At present, in the turning process of large-scale bearing rings in my country, single-tool machining is still used for processing. Medium and small bearing rings have gotten rid of single-tool machining. Most of the forgings are processed by multi-tool semi-automatic and fully automatic lathes. Turning can realize one-time processing of different parts of the same forging, but if there are many processing parts of the forging, and one lathe cannot realize the overall processing of the forging, multiple lathes are required to process different parts of the bearing ring in turn , in the entire processing process, multiple workers are required to work, to carry out manual loading and unloading, and the operation mode is "many people, one machine" or "one person, one machine". The production efficiency is low, and it is time-consuming and laborious.

During the processing process, the lathe clamps and positions the forgings through the clamps, but the existing hydraulic automatic clamps often cause inaccurate clamping and positioning of the clamps due to manual feeding errors, oil cylinder pressure, and workpiece position errors. The degree is between 3‰-5‰), not only the scrap rate is high, but also it is easy to cause the workpiece to be scrapped or the props to be damaged
