AI Technical Summary

Problems solved by technology

In the process of processing, the commonly used bushings cannot firmly hold the shaft head, resulting in relative movement between the shaft head and the bushing and friction of the shaft head
Due to friction, the shaft head 12 is often damaged during the rotation or clamping process, resulting in a greatly reduced service life of the workpiece

Embodiment Construction

[0022] The present invention is described in detail below in conjunction with accompanying drawing:

[0023] like figure 2 , image 3 and Figure 4 As shown, the shaft sleeve includes an outer sleeve 1 and an inner sleeve 2. The sheath 1 is provided with a sheath lumen 11 . The inner diameter of the sheath lumen 11 becomes smaller in axial direction from the sheath end 12 . The inner sleeve 2 is provided with an inner sleeve lumen 21 . The outer diameter of the inner sleeve 2 gradually increases from the axial diameter of the end portion 22 of the inner sleeve. That is, along the same direction, the change of the outer diameter of the outer sleeve lumen 11 is opposite to the change of the outer diameter of the inner sleeve. A radial through slot 23 extending in the axial direction is provided at the end portion 22 of the inner sleeve. The number of radial through slots 23 is three, so that the end portion 22 of the inner sleeve forms three blades 24 .

Abstract

The invention discloses a shaft sleeve. The shaft sleeve is characterized by comprising an outer sleeve and an inner sleeve; the outer sleeve is provided with an outer sleeve cavity; the inner sleeve is provided with an inner sleeve cavity; the inner sleeve is arranged in the outer sleeve cavity in a form of moving in an axial direction; and the inner sleeve is under a radial pressure of the wall of the outer sleeve cavity when moving along the axial direction so as to reduce the diameter of the inner sleeve cavity. By using the detachable shaft sleeve, a shaft end is effectively protected from being worn, and therefore, a shaft is protected. The clamping force to the shaft can be increased in the mounting process of the shaft sleeve, so that the shaft sleeve is firmer is clamping and more convenient to use.

Description

technical field [0001] The invention relates to a shaft sleeve. Background technique [0002] figure 1 Shown is a schematic structural view of a workpiece 10 . It includes a workpiece body 11 and shaft heads 12 arranged at two ends of the workpiece body 11 . The diameter of the shaft head 12 is much smaller than the diameter of the workpiece body 11 . This kind of workpiece is also called large workpiece small shaft head structure. During the processing of such workpieces, the workpiece body 11 needs to be driven to rotate through the shaft 12 for grinding or other processing. Therefore, it is necessary to clamp the shaft head 12 or lift the shaft head 12 to achieve the purpose of driving the shaft head 12 and further driving the workpiece body 11 to rotate. During the machining process, the commonly used bushings cannot firmly hold the shaft head, resulting in relative movement between the shaft head and the bushing and friction against the shaft head. Due to friction...
