Shaft sleeve self-locking device, dismounting method and excavator
The invention discloses a shaft sleeve self-locking device, a dismounting method and an excavator. The shaft sleeve self-locking device comprises a shaft sleeve, a special-shaped expansion sleeve, a first connecting piece, a second connecting piece and a sliding block, and the shaft sleeve is embedded into the inner circle faces of the two ends of a bucket rod front shaft assembly; the special-shaped expansion sleeve comprises a disc part and a conical part which are integrally connected, an elastic kerf is formed in the disc part, the expansion sleeve outer conical surface of the conical part is attached to the inner conical surface of the end of the bucket rod front shaft assembly, and the expansion sleeve inner circular surface is attached to the outer circular surface of the shaft sleeve; the first connecting piece is connected with the special-shaped expansion sleeve and the outer end face of the bucket rod front shaft assembly. The bottom end of the second connecting piece makes contact with the inner conical face of the bucket rod front shaft assembly through a compressed spring and a sliding block, the sliding block moves to the upper end face of the sliding block along with tightening of the second connecting piece to be attached to the outer end face of an inner groove of the bucket rod front shaft assembly, and self-locking is formed. Self-locking and three-axis self-centering of the bucket rod front shaft assembly, the sliding block and the special-shaped expansion sleeve are achieved, and the problems that a shaft sleeve is abraded, and a friction plate and the bucket rod front shaft assembly crack are solved; and quick disassembly can be realized.
本发明公开了一种轴套自锁装置及拆卸方法和挖掘机，装置包括轴套、异形涨套、第一连接件、第二连接件和滑块，轴套嵌入斗杆前轴组件两端的内圆面；所述异形涨套包括一体连接的圆盘部和圆锥部，圆盘部上设有弹性切缝，圆锥部的涨套外锥面与斗杆前轴组件端部的内锥面贴合，涨套内圆面与轴套外圆面贴合；第一连接件连接异形涨套与斗杆前轴组件的外端面；第二连接件底端通过压簧和滑块接触斗杆前轴组件的内锥面，滑块随着第二连接件的拧紧移动至滑块的上端面与斗杆前轴组件的内槽外端面贴合，形成自锁。本发明使得斗杆前轴组件、滑块、异形涨套实现自锁以及三轴自定心，防止轴套磨损以及摩擦片、斗杆前轴组件开裂等问题；还能够实现快速拆卸。
