Abstract

Disclosed is a centralizer for reaming holes with a variable diameter hinge, which includes: a first shell, a second shell, a centralizing block, an inner tube of the centralizer, and a diameter-adjusting nut; the first shell is connected to the second shell; The inner tube of the centralizer is connected in the first shell; the centralizing block runs through the side wall of the first shell, and then connects with the inner tube of the centralizer through a dovetail structure, and the dovetail structure includes a dovetail groove and a dovetail tenon; Above, the plane where the bottom surface of the dovetail slot intersects the axis of the centralizer, and the projection of the axis of the centralizer on the plane where the bottom surface of the dovetail slot is parallel to the length direction of the dovetail slot; the adjusting nut and the inner tube of the centralizer are connected by threads, and The diameter-adjusting nut is arranged between the first housing and the second housing, and the two end surfaces of the diameter-adjusting nut are respectively attached to one end surface of the first housing and one end surface of the second housing . The centralizer of the invention can improve the processing level of the deep and long inner hole, improve the processing quality, improve the efficiency of reaming and reaming, and is easy to operate.

Description

technical field [0001] The invention belongs to the field of centralizers, in particular to a centralizer with variable-diameter hinge reaming. Background technique [0002] In the process of mechanical processing, the processing of the inner hole of deep and long pipe fittings is a difficult problem to solve. When processing the inner hole, it is often difficult to ensure the processing quality so that it can meet the technical requirements, especially when the precision requirement is relatively high and the inner hole depth is large. Processing is more difficult. The main reason for this phenomenon is that when the tool is machining the inner hole of the pipe, as the machining depth of the tool increases, the length of the drive shaft of the tool will also increase accordingly. The work of the tool is powered by the drive shaft. The increase in length will inevitably lead to the offset between the centerline of the drive shaft and the centerline of the pipe fitting in th...
