Problems solved by technology

In order to ensure the flatness of the middle surface of the lower outlet seat, the perpendicularity between the surfaces and the perpendicularity between the center axis of the hole and the surface, etc., CNC machine tools must be used to complete the processing of each process of the lower outlet seat. However, there are The disadvantages are: 1. If the processing of the lower outlet seat must be completed by a CNC machine tool, it is necessary to purchase a CNC machine tool, which will greatly increase the manufacturing and processing costs; The lower outlet seat is processed on an ordinary machine tool, but due to the poor positioning performance of the existing fixture of the ordinary machine tool, the dimensional accuracy of the processed lower outlet seat does not meet the requirements, especially the central axis of the threaded hole 1603 relative to the half cross-section 1602. The verticality becomes larger, so that the contact area between the lower outlet seat and the soft connection becomes smaller during installation, which affects the conductivity of the resistance circuit of the solid-sealed pole. When a large current passes through, the entire part may be scrapped. big security risk

Abstract

The invention provides a fixture device for machining a lower wire outlet base of a solid-sealed polar pole on a general machine tool. The fixture device comprises a base plate; a front plate is vertically arranged at one end of the upper end face of the base plate; a front jacking component for horizontally and axially jacking the lower wire outlet base is arranged on the front plate; a rear plate is vertically arranged at the other end of the upper end face of the base plate; a cushion block is arranged at the inner side of the rear plate; a left supporting plate and a right supporting plate are respectively arranged at the two sides of the middle part of the upper end face of the base plate; an upper positioning plate is supported on the upper end faces of the left and right supporting plates; a tapered iron pressing component for vertically and radially pressing the lower wire outlet base is arranged on the base plate between the left and right supporting plates; the front jacking component moves forwards to axially push one end face of the lower wire outlet base so that the other end face of the lower wire outlet base is tightly pressed on the cushion block in order to realize axial positioning; the tapered iron pressing component moves via a bevel so that the lower wire outlet base can be lifted in the radial direction and the upper plane of the lower wire outlet base is horizontally close to the lower plane of the upper positioning plate in order to realize radial positioning. The fixture device disclosed by the invention is capable of guaranteeing the precision of a lower wire outlet base product machined by a general machine tool so that the electric conductivity of a resistance loop of the solid-sealed polar pole is good, the potential safety hazards are reduced, and the manufacturing cost and machining cost can be greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to a fixture device for processing outlet sockets under solid-sealed poles on ordinary machine tools. Background technique [0002] The solid-sealed pole is mainly used in high-voltage vacuum circuit breakers, and the lower outlet seat on the solid-sealed pole is an important part in the resistance circuit of the solid-sealed pole. Such as Figure 7 As shown, generally the lower outlet seat is a columnar structure whose end face I1601 is perpendicular to the half cross-section 1602 and is formed by precision casting. Two threaded holes 1603 are required to be drilled on the half cross-section 1602, and the central axis of the threaded hole 1603 must be Guaranteed to be perpendicular to the half cross section 1602 . In order to ensure the flatness of the middle surface of the lower outlet seat, the perpendicularity between the surfaces and the perpendicularity between t...
