Embodiment Construction

[0009] The present invention will be further described below in conjunction with drawings and embodiments.

[0010] Such as figure 1 , As shown in 2, the main shaft structure of the tailstock is mainly composed of the main shaft 6, the upper body shell 7, the lower body shell 1, the top 15, the main shaft moving driving screw 8, and the nut 9.

[0011] Tailstock main shaft 6 profile is octahedron structure, and four guide rail surfaces wherein cooperate with the guide rail surface of tailstock body shell, two guide rail surfaces below tailstock main shaft 6 are installed two guide rails 2, are fixed by bolt 3. The guide rail 2 is easy to process and install, and has high hardness, which can reduce the friction coefficient between the main shaft and the guide rail surface of the lower body shell 1, and improve the life span of the main shaft 6 and the lower body shell 1.

[0012] The tailstock body shell is composed of the upper body shell 7 and the lower body shell 1 with an ...

Abstract

The invention relates to a main axle structure of polygonal tail support, which is formed by upper frame, lower frame, main axle moving driving screw, and nut, wherein the main axle is a octahedron; the tail support frame is connected by upper and lower frames to form a main axle with an octahedron inner hole at the middle that matches the main axle; the lower two track surfaces of main axle via the track connects two track surfaces of lower frame; the upper two track surfaces of main axle are sliding connected to the two track surfaces of upper frame. The invention has simple adjustment, and confirmed accuracy of main axle.

Description

technical field [0001] The invention relates to a tailstock spindle structure of a machine tool, in particular to a polygonal tailstock spindle structure of a special machine tool. Background technique [0002] At present, the exterior structure of the tailstock spindle commonly used on various machine tools is a cylinder. The tailstock spindle moves in the cylindrical hole on the tailstock body shell. The front end of the tailstock spindle is equipped with a top. For tight workpieces, the accuracy of the movement of the tailstock spindle directly affects the accuracy of the workpiece being processed. Contents of the invention [0003] The present invention aims to solve the technical problems of the existing structure of the main shaft of the tailstock of the machine tool, which requires high matching precision between the body shell hole and the main shaft of the tailstock, and makes it difficult to process and install. The hole machining of the main shaft, the tailstoc...
