Main shaft system of multi-wire cutting machine

Abstract

The invention discloses a main shaft system of a multi-wire cutting machine. The main shaft system comprises a wire roller and a mandrel, wherein the wire roller, the mandrel and a screw nut are axially fastened and connected, the upper end of the mandrel is fastened with a belt wheel through an expansion sleeve and is used for torque input, the main shaft system also comprises a first spherical bearing and a second spherical bearing, the first spherical bearing and the second spherical bearing realize the support positioning with the two ends of the wire roller, the first spherical bearing is directly connected with the mandrel, a slide sleeve is arranged between the second spherical bearing and the mandrel, a key is arranged between one end of the wire roller and the mandrel, a bearing seat is arranged outside the upper end of the mandrel, a pair of angular contact ball bearings and a first cylindrical roller bearing are arranged between the bearing seat and the mandrel, the bearing seat is fixedly connected with a cold water sleeve, a front support seat is arranged outside the lower end of the mandrel, and a second cylindrical roller bearing is arranged between the front support seat and the mandrel. The main shaft system of the multi-wire cutting machine has the advantages that the service life is long, the cooling environment is good, the sealing effect of the main shaft system is good, the protection performance is good, in addition, the high-speed and stable operation of the wire roller is realized, the processing precision of workpieces is ensured.

Description

[0001] technical field [0002] The invention belongs to the field of multi-wire cutting machines, and in particular relates to a main shaft system of a multi-wire cutting machine. [0003] Background technique [0004] As a multi-wire cutting machine, the stability and high precision of the spindle system play a vital role in the processing quality of the workpiece. The two wire rollers of the spindle system have high requirements for running accuracy and stability. Frequent movement, in order to ensure smooth operation and precision, the mandrel drives the wire roller through the end face key. During the cutting process, the entire working environment is very harsh, and the protection requirements for the inside of the wire roller are very high. However, the existing multi-cutter spindle system has poor sealing effect and poor cooling environment, and the working life of the system is generally relatively short. In order to solve this series of problems, it is best to de...
