Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an automatic material discharging structure of a chuck of a numerically controlled lathe. Background Art

[0002] At present, the back-axle discharging device of the lathe on the market is hard-connected together by a push rod and a ejector rod through threaded locking. When discharging softer materials, the ejector rod is easy to damage the surface of the product. Sometimes, in order to solve this problem, the ejector rod is replaced with a soft material, such as copper, aluminum, etc., but it will be deformed or worn after long-term use. Basically, a flexible discharging structure of a push rod + spring + ejector rod is developed for this situation, which can not only ensure the service life of the ejector rod but also spit out the product without damaging the surface of the product. However, once the discharging structure is damaged, it is not easy to disassemble, which affects the efficiency of replacing parts. Utility Model Content
