Description

Technical Field

[0001] This utility model relates to the field of valve guide processing technology, specifically to an automated valve guide processing device. Background Technology

[0002] Valve guides are the guiding devices for the valves of an automotive engine, installed on the cylinder head. Their main function is to ensure the valves perform reciprocating linear motion, to ensure proper contact between the valve and the valve seat, and to transfer the heat from the valve stem to the cylinder head. Currently, the production and processing of valve guides requires the use of CNC lathes for machining.

[0003] Currently, when valve guides are machined using CNC lathes, the production mode is generally manual loading and unloading, with an actual machining cycle of about 1 minute. The auxiliary loading and unloading time is 10 seconds, accounting for 16% of the total auxiliary time. Moreover, one person can only operate two machine tools, resulting in low production efficiency and increased costs that cannot meet the requirements for mass production. Therefore, an automated valve guide machining device is proposed to solve the above-mentioned problems. Utility Model Content
