A contact positioning tool

Abstract

The invention relates to an accessory of a drilling machine, in particular to a contact positioning tool. The contact finger positioning tool includes a base and a center positioning shaft rotatably assembled on the base. Two clamping positioning parts for clamping the contact fingers are arranged on the center positioning shaft, and an indexing mechanism is also arranged between the center positioning shaft and the base. The indexing mechanism includes an indexing disc and a clamping block set in the indexing disc. The clamping block is clamped into the concave part of the concave-convex structure to position the center positioning axis in the circumferential direction. The contact positioning tool is also equipped with a drilling template. To determine the position of the tooling relative to the rig. The contact finger positioning tool determines the position of the tool relative to the drilling machine through the drilling template, positions the contact finger on the central positioning axis by clamping the positioning piece, and determines the angle between two adjacent perforations in the circumferential direction through the indexing mechanism. Due to the original plan of using fitters to determine the drilling position, the machining accuracy and the stability of the contact fingers during processing are improved, thereby improving the quality of the processed contact fingers.

Description

technical field [0001] The invention relates to an accessory of a drilling machine, in particular to a contact positioning tool. Background technique [0002] The current high-voltage AC and DC isolating switch products all use the plug-in structure of contacts and contacts to open and close. In order to ensure the quality of the products, there are strict requirements on the processing and size of the contacts. Such as figure 1 As shown, there is a ring structure 101 at one end of the stylus, which is provided with two rows of perforations 102 evenly arranged along the circumferential direction, and elastic pieces 103 evenly arranged along the circumferential direction at the other end of the stylus. At present, the method of machining in the machining center is often used to drill the contact fingers, but when machining in the machining center, not only the processing tool for positioning the contact fingers is required, but also the processing cost is very expensive; if ...

Problems solved by technology

At present, the method of processing in the machining center is mostly used to drill the contact fingers, but when processing in the machining center, not only the processing tool for positioning the contact fingers is required, but also the processing cost is very expensive; if the fitter is used to mark the The method of drilling again is inefficient, and the precision of processing is also very low, and the error is very large, which cannot meet the quality requirements of the product.
