Machining fixture for transformer clamp tape limb plate and use method of machining fixture

Abstract

The invention relates to a machining fixture for a transformer clamp tape limb plate and use of the machining fixture. The machining fixture is provided with a positioning plate, two side plates, two pressing plates and a plurality of fastening pieces, wherein the two side plates are connected with the two ends of the positioning plate for clamping installation so that a fastening tool frame capable of bearing a workpiece can be formed, and the workpiece is clamped and fixed into the fastening tool frame through the multiple fastening pieces. A use method comprises the following steps that the machining fixture is applied to conducting clamping installation on a single transformer clamp tape limb plate piece; the machining fixture is applied to conducting clamping installation and arrangement on multiple transformer clamp tape limb plate pieces; and after machining is finished, the workpiece is taken out. According to the machining fixture, by means of the angle adjustment of the clamp and the clamping function at multiple positions, machining of installation holes of the clamp tape limb plate on a numerical control machine tool is achieved easily, accurate and rapid installing and clamping of the workpiece on the machine tool are achieved within the allowed error ranges of sizes, precise angle positioning is successfully achieved, the production efficiency is improved, the workpiece quality is stabilized, and convenience and rapidness are brought to production.

Description

technical field [0001] The invention relates to a tool used in the manufacture of a transformer, in particular to a clamping tool for machining a transformer clip, a strap, a limb plate, and a method for using the same. Background technique [0002] The clamp drawstring limb plate is an important component of the transformer clamp, and the holes on it are used to install the transformer drawstring, which is the main force-bearing structural component. During the processing of this part, each dimension requires high precision, especially the angle of the hole is extremely strict. However, due to the complex and irregular dimensions of the part, it is difficult to clamp the part on the CNC machine platform, and it cannot be fixed according to the ideal angle. , which brings great difficulties to the processing process, especially the angle of the hole cannot be guaranteed. [0003] The previous solution was to add spacers to adjust between the workpiece and the machine tool p...
