A long rod processing method and auxiliary tooling for long rod processing

Abstract

The invention discloses a long rod piece machining method and an auxiliary tool for long rod piece machining. The machining method comprises the following steps that first, a groove which extends in the length direction of a long rod piece is machined in the long rod piece; and second, the long rod piece is fixedly buckled on a base of the auxiliary tool, the groove of the long rod piece is correspondingly matched with a protruding part which extends or is distributed in the length direction of the long rod piece and is arranged on the base in an inserting mode, and then the outer surface of the long rod piece is subjected to machining. According to the long rod piece machining method, after the groove is machined, the long rod piece is fixedly buckled on the base, the groove of the long rod piece is matched with a groove correspondingly formed in the base in an inserting mode, the protruding part on the base correspondingly supports the groove of the long rod piece, a cavity formed by the groove of the long rod piece is filled correspondingly by the protruding part on the base, accordingly, the intensity of the long rod piece can be effectively improved, when the outer surface of the long rod piece is machined, deforming of the long rod piece can be effectively avoided, and then the machining accuracy of the long rod piece is improved.

Description

technical field [0001] The invention relates to a method for processing long rods and auxiliary tooling for processing long rods. Background technique [0002] In the field of machinery, long rods with grooves extending along the length are often encountered, such as figure 1 , figure 2 The shown insulation guide 100 is applied in the circuit breaker field. The insulation guide is attached to the surface of the insulation pull rod of the circuit breaker during use to protect the surface of the insulation pull rod from damage and play an important role in insulation. The insulating guide 100 is made of polytetrafluoroethylene, and one side of the insulating guide 100 is provided with a groove extending along the length direction of the guide. The radius of the cylindrical surface where the arc-shaped groove bottom surface 101 is located is R16.8mm, and the side of the insulating guide 100 away from the notch of the groove has an arc-shaped side surface arranged concentrica...
