Semi-closed numerical control lathe center frame

Abstract

The invention discloses a semi-closed numerical control lathe center frame. A first guide block assembly is arranged at one end of a roll-over frame, and the other end of the roll-over frame is connected with a base through a roll-over frame rotary shaft and can rotate around the roll-over frame rotary shaft; a second guide block assembly is arranged on the base, and a fixing screw rod is arranged between the roll-over frame and the base; a rotary block assembly is connected with the base through a rotary block rotary shaft, and a rotary block adjusting screw rod is arranged on the base and abuts against the plane on one side of the rotary block assembly. By adjusting guide blocks and rotary blocks manually, the semi-closed numerical control lathe center frame achieves machining of thin-wall cylindrical elements, and solves the clamping problem of a numerical control lathe in machining thin, long and thin-wall parts. After the roll-over frame is opened, the parts are clamped on a three-jaw chuck of the numerical control lathe, and after primary clamping of the thin-wall cylindrical elements is finished, the roll-over frame is closed and fixed through a nut on the fixing screw rod; the guide blocks and the rotary blocks are adjusted, so that the middle portions of the thin-wall cylindrical elements are clamped. The semi-closed numerical control lathe center frame can meet the requirement that the numerical control lathe clamps the thin-wall cylindrical elements.

Description

technical field [0001] The invention relates to a numerically controlled lathe in the technical field of mechanical processing, in particular to a semi-closed numerically controlled lathe center frame. Background technique [0002] The working surface of DMG CNC lathe CTX510 is inclined, and it has a hydraulic steady rest. [0003] Since the part to be processed is a thin-walled cylindrical part, the hydraulic steady rest cannot precisely control the strength of the clamped part, and it is easy to clamp the part. In order to meet the requirements of the lathe for processing thin-walled cylindrical parts, it is necessary to design an openable manual center frame, and in order to facilitate the operation of the operator, the adjustment parts should face the operator. Do not find description or report similar to the present invention at present, also do not collect similar data both at home and abroad. Contents of the invention [0004] The present invention aims at the abo...
