Embodiment 1

[0021] The yT23 rock drill is a high-efficiency air-leg rock drill, mainly used for rock drilling in mining roadway excavation, and also an important tool in railway, water conservancy construction and national defense stonework projects. It can perform wet rock drilling on medium-hard and hard rocks , can drill horizontal and inclined blastholes.

[0022] Such as Figure 5 As shown, the head 90 involved in this design is one of the main parts of the yT23 rock drill. The part is roughly cylindrical, with a cylindrical surface 91, a brazing support frame 92, an ear plate 93 provided with tie rod bolt holes, a cylindrical protrusion 94 and an inner hole 95, and the blank is mostly a forging or a precision casting. In the grinding process of the inner hole 95 of the machine head, due to the irregular shape of the parts, a fork-shaped brazing support frame 92 protrudes from the cylindrical surface 91 at the left end, and two lug plates 93 with tie rod bolt holes protrude from the...

Abstract

The invention discloses a flexible bushing. The flexible bushing is a sleeve-shaped part as a whole. The flexible bushing includes an annular sleeve body, and a plurality of third long grooves are opened in the axial direction on the wall of the annular sleeve body. Both ends of the three long grooves run through the two ends of the annular sleeve body, and the third long groove divides the annular sleeve body into several independent elongated fan-shaped pressing blocks; The connecting head is connected to form a sleeve-shaped part; the connecting head is provided with protrusions extending outward along the axial direction on the two end faces of the annular sleeve body, and the protrusions on the two end faces of the annular sleeve body are alternately arranged. The advantage is that the inner hole of the flexible bush is inserted into the parts, and can shrink or expand in the radial direction under the action of external force, so that the irregular shaft parts are convenient for positioning and installation.

Description

technical field [0001] The invention relates to a flexible bush and belongs to the technical field of process equipment for machining. Background technique [0002] In the prior art, it is difficult to clamp some irregular shaft parts. The general three-jaw tooling is not convenient for clamping, and the clamping accuracy of the conventionally designed two-jaw tooling is not too high. Contents of the invention [0003] The purpose of the present invention is to provide a flexible bush, which can shrink or expand radially under the action of external force, so that the irregular shaft parts can be easily positioned and installed. [0004] The specific technical solution is as follows: a flexible bushing, the flexible bushing is a sleeve-shaped part as a whole, the flexible bushing includes an annular sleeve body, the annular sleeve body is divided into two half sleeves in the axial direction, and two half sleeves The sleeve body of the sleeve is provided with a plurality o...
