Repairing device for lathe center and using method of repairing device

Abstract

The invention relates to a repairing device for a lathe center and a using method of the repairing device. The repairing device for the lathe center comprises a first jacking and supporting piece, a second jacking and supporting assembly, a grinding assembly and a heart-shaped claw; the second jacking and supporting assembly comprises a fixing and holding piece, an elastic element and a jacking and supporting piece; and the grinding assembly comprises a guide rail, a sliding block, a motor and a grinding tool. According to the repairing device for the lathe center, the structure is simple, adopted parts are common and few, the center repairing cost is reduced, center scrap caused by high center repairing cost is reduced, and the center scrap rate is reduced; the first jacking and supporting piece and the second jacking and supporting assembly are matched to jack the two ends of a to-be-repaired center at the same time, so that the coaxiality of the to-be-repaired center during repairing is higher, and the phenomenon of low repairing precision caused by low coaxiality is reduced; and the jacking and supporting end of the jacking and supporting piece is provided with a receding notch, so that the end of the to-be-repaired center can be repaired, the center is repaired more perfectly, and the accuracy of repairing the center is further improved.

Description

technical field [0001] The invention relates to the technical field of lathe tops, more specifically, it relates to a repairing device for a lathe top and a method for using the same. Background technique [0002] It is very common to use lathes to machine long bars. During the processing, it is necessary to use the tip to withstand the end of the long bar workpiece for support, so as to avoid bending and torsion during the machining of the long bar by the turning tool. Among them, the top can play a supporting and centering role and is indispensable. Therefore, the top of the lathe is an important component in metal cutting. As one of the most commonly used clamping tools on lathes, the tip is often worn or damaged due to improper use or excessive cutting force during use. When the live center head is worn out, it will directly affect the processing quality of the workpiece, and even cause the workpiece to be scrapped. [0003] If the worn top is not repaired, it will ca...
