Live center special for carving machine

Abstract

The invention relates to the field of machining, in particular to a live center special for a carving machine. The live center comprises a movable shaft, a center movable shaft, an outer sleeve, a live center body and a hand-cranking wheel. The shaft shoulder end of the movable shaft is sleeved with the live center body. The external thread end of the center movable shaft is screwed into the other end of the movable shaft, and the other end of the center movable shaft is fixedly connected with the end face of the hand-cranking wheel. The movable shaft is sleeved with the outer sleeve. Linear bearings are arranged between the outer sleeve and the movable shaft. A locking cover is arranged at one end, close to the live center body, of the outer sleeve, a locking nut is arranged at the other end of the outer sleeve, and the locking cover and the locking nut are used for locking the live center special for the carving machine to the carving machine. According to the live center, the movable shaft and the outer sleeve are connected through the linear bearings, a gap between the movable shaft and the outer sleeve is eliminated, and a locking screw carries out locking from the end face of the hand-cranking wheel, so that the locking effect is firmer and safer.

Description

technical field [0001] The invention relates to the field of processing machinery, in particular to a movable top dedicated to an engraving machine. Background technique [0002] Mechanical engraving machine is a general-purpose mechanical equipment widely used in wood industry, advertising industry, craft industry, mold industry, construction industry, printing and packaging industry, decoration industry, and can carve woodworking board, density board, acrylic organic board, PVC board, Hibiscus board, two-color board, marble, fireproof board, rubber board, glass and other different materials. According to different engraving workpieces, mechanical engraving machines can be divided into plane engraving machines and cylindrical engraving machines. The plane engraving machine can carry out surface relief on the plate, and the cylindrical engraving machine can carry out engraving on the cylindrical workpiece. The processed products can be applied to the columns or other parts ...

AI Technical Summary

Problems solved by technology

During the operation of the cylindrical engraving machine, the tail of the workpiece needs to be fixed by the top. The existing top structure locking screw is above the top. When the screw is locked, the intermediate shaft will be pushed down a little, which is easy to cause eccentricity, and the casing and the movable shaft If there is no gap, it cannot expand and contract. If there is a gap, it will affect the processing accuracy and reduce the engraving accuracy.
