Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as Figure 1-2 As shown, the tool for repairing bolt threads includes a fixed base body 1 in a rectangular frame, the corresponding left and right sides of the fixed base body 1 are respectively provided with through windows 11, and a triangular file 2 with a triangular cross section. The through window 11 runs through the left and right sides of the fixed seat body 1, and the triangular file 2 is arranged in the through window 11 to move up and down. Elastic guide structure 3, and one of the three file sides of the triangular file 2 corresponding to the upper end of the fixed seat body 1 is a fixed surface 21, wherein the fixed surface 21 of the triangular file 2 is parallel to the upper end of the fixed seat body 1, and the triangular file 2 is parallel to the upper end of the fixed seat body 1. One of the three file co...

Abstract

The invention relates to a tool for repairing threads of bolts and solves the technical problem of high cost of bolt repairing tools in the prior art. The tool comprises a fixing seat body, penetrating windows, a triangular file and an elastic guide structure; one, corresponding to the upper end of the fixing seat body, of three file side surfaces of the triangular file is a fixing surface; one, corresponding to the fixing surface, of three file corners of the triangular file is a repairing corner; a gap is formed between the repairing corner of the triangular file and the lower end of the fixing seat body; the repairing corner is inserted in a thread of a to-be-repaired bolt; an axial driving mechanism is arranged between the triangular file and the fixing seat body; and the tool furthercomprises at least one fixing mechanism for fixing the end of the to-be-repaired bolt and rotating the to-be-repaired bolt. The tool has the advantages as follows: the threads of the bolts can be repaired by the aid of the triangular file, and the tool has the good repairing effect, is applicable to the bolts in different specifications and has the relatively good repairing effect on triangular threads, rectangular threads and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a tool for repairing bolt threads. Background technique [0002] As a common fastener, a bolt is generally used to cooperate with a nut to form a fastening connection, and the threaded connection to the mechanical equipment connection is realized through the external thread of the bolt. Bolts and nuts have good connection performance and simple structure, and are widely used in the field of mechanical equipment. However, in daily use, the bolts are often rusted or deformed by external forces, resulting in bolts that cannot be used normally. In order to save costs, it is necessary to The threaded teeth of the bolts are repaired. The repair of common bolt threads generally relies on the die to repair, that is, the thread of the corroded or deformed bolt is repaired by manually rotating the die or the bolt. The repair is difficult and inefficient. Therefor...
