Embodiment Construction

[0015] In order to clearly illustrate the technical features of the present solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings. It should be noted that components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted herein to avoid unnecessarily limiting the present invention.

[0016] Such as figure 1 As shown, the special mandrel tooling for the dynamic balance of the high-precision machine tool pulley includes the mandrel body 1, the spring expansion sleeve 2 and the lock nut 3.

[0017] Both ends of the mandrel body 1 are outer round terminals 11 with a size of Φ30h6, which are used for connecting to a dynamic balancing machine tool. The middle part of the mandrel body 1 is a tapered outer circle 12 with a taper of 1:20, and the tapered outer circle 12 is used to match and connect the pulley 4 ...

Abstract

The invention aims to provide a special mandrel tool for dynamic balance of a belt wheel of a high-precision machine tool, and the special mandrel tool is used for solving the technical problem abouthow to improve dynamic balance performance of a machine tool transmission belt wheel. The special mandrel tool for dynamic balance of the belt wheel of the high-precision machine tool comprises a mandrel body, a spring tightening sleeve and a locking nut, wherein the two ends of the mandrel body are equipped with outer circular terminals which are connected with a dynamic balance machine tool, andthe middle part of the mandrel body is equipped with a taper outer circle which is matched with a belt wheel hole; and the spring tightening sleeve is arranged between the taper outer circle and thebelt wheel hole, and a the locking nut for tightening the spring tightening sleeve is mounted between the mandrel body and the outer end of the belt wheel. The special mandrel tool has the beneficialeffects that: positioning gap errors between the outer circle of the dynamic balance mandrel and the belt wheel hole in the prior art are completely eliminated, and dynamic balance precision of the belt wheel can be greatly improved, so that stability and balance of the machine tool are guaranteed.

Description

technical field [0001] The invention relates to the technical field of mandrel tooling for belt pulleys of machine tools, in particular to mandrel tooling for dynamic balancing of high-precision machine tool belt pulleys. Background technique [0002] With the continuous improvement of the level of science and technology in our country, the precision requirements of machining accessories are also getting higher and higher, thus putting forward higher requirements for the precision and speed of the CNC machining machine tools. As the pulley of the power transmission part of the CNC machine tool, since it rotates with the motor at high speed, if its dynamic balance is not handled well. Then, when the CNC machine tool is working at high speed to process the workpiece, it will cause the vibration of the machine tool, which will directly affect the surface processing quality and machining accuracy of the workpiece. Therefore, it is very important to seek a technical solution for...
