AI Technical Summary
Technical Problem
When the existing lathe back shaft material spitting device is spitting softer materials, the feed rod may easily damage the product surface and will deform or wear after long-term use.
Method used
A flexible material-spraying structure of CNC lathe back shaft chuck is designed, using a combination of push rod, spring and feed rod to provide soft thrust through the elastic characteristics of the spring, avoiding the feed rod directly exerting great force on the product.
Benefits of technology
It realizes that the product is flexible to be spit out without damaging the product surface, extending the service life of the feed rod and avoiding product deformation or embossment.

Abstract
The utility model provides a flexible discharging structure of a back shaft chuck of a numerical control lathe, and relates to the field of machining. The flexible discharging structure of the back shaft chuck of the numerical control lathe comprises a guide rod, a connector is fixedly connected to the left end of the guide rod, a through hole communicated with the right end is formed in the left end of the guide rod, a convex hole communicated with the right side is formed in the left side of the connector, and a push rod is movably connected into the through hole. And the left end of the push rod is fixedly connected with a spring. According to the flexible discharging structure of the back shaft chuck of the numerical control lathe, through the flexible discharging structure of the push rod, the spring and the ejector rod, when the push rod provides force to push the spring forwards, due to the elastic characteristic of the spring, small force can be provided for the ejector rod in the initial stage, and the ejector rod makes contact with a product slowly; therefore, the ejector rod can be gently attached to the product at the moment of contacting with the product, deformation or impressing of the product is avoided, the service life of the ejector rod can be guaranteed, and the product can be ejected out without damaging the surface of the product.
