Abstract

The invention discloses a dedicated tool for machining a reamer shell sliding groove. The dedicated tool for machining the reamer shell sliding groove comprises a sliding groove electrode body. The two sides of the sliding groove electrode body are provided with sliding groove male dies. A fixing plate is fixedly connected with the upper part of the sliding groove electrode body. The sliding groove electrode body, the sliding groove male dies and the fixing plate are formed in an integrated manner. The side face of the fixing plate is provided with multiple through holes a. The fixing plate isprovided with a cutter bar connection piece. A cutter bar is fixedly connected to the cutter bar connection piece. The dedicated tool for machining the reamer shell sliding groove and a method for machining the shell sliding groove with the dedicated tool solve the problems that since a reamer shell is large in length and diameter and is provided with inclined grooves, a dedicated tool is neededfor fixation, and machining interference exists between the cutter bar and the shell during sliding groove machining.

Description

technical field [0001] The invention belongs to the mechanical processing technology of rock-breaking tools for petroleum and natural gas and geological drilling engineering, and in particular relates to a special tool for processing the chute of a reamer shell, and also relates to a processing method for processing the chute of the reamer shell. Background technique [0002] During the drilling process, the blades of the reamer protrude along the chute of the casing, so that the cutting teeth on the blades contact and scrape and break the well wall rock, thereby enlarging the diameter of the well. [0003] The chute of the eye reamer housing is a keyway with a certain oblique angle on the housing wall. The chute provides a sliding track for extending or retracting the blade. Due to the long length, large diameter and chute of the casing, special and complex fixtures are required to fix it on the worktable, and the processing technology of the chute is complex, which is pro...
