Anti-deformation positioning device and positioning method for oblique cutting of copper bars

Abstract

The anti-deformation positioning device for oblique cutting of copper bars includes a strip-shaped reference block, a pair of reference positioning clamping blocks are arranged on the reference block, and an adjustment guide rod is provided on each side of the two reference positioning clamping blocks. A group of movable positioning clamping blocks are respectively provided on the root adjusting guide rods; a reference clamping block locking screw is provided on the reference positioning clamping block, and a movable clamping block locking screw is provided on the movable positioning clamping block; the reference positioning clamp The side of the clamping block is provided with a reference jaw, and the two sides of the movable positioning clamping block are respectively provided with a movable jaw; the lower end of the locking screw of the movable clamping block is provided with a rubber block; the middle part of the locking screw of the movable clamping block is provided with a There is a tapered surface, and the movable positioning clamping block is provided with a guide hole at the bottom of the movable jaw of the reference positioning clamping block. The guide hole is provided with a slide block that can slide along the guide hole, and the outside of the slide block is provided with a rubber pad. The device of the present invention is used to clamp the copper bar to be obliquely cut, which is easy to operate, not easy to loosen, ensures the positioning accuracy, and makes the cutting accuracy high.

Description

technical field [0001] The invention relates to a positioning technology for oblique cutting of copper bars, in particular to an anti-deformation positioning device for oblique cutting of copper bars and a method for positioning copper bars using the device. Background technique [0002] Copper bars, also known as copper bus bars or copper bus bars, are made of copper and have a rectangular or chamfered (rounded) rectangular cross-section. The copper bar has low resistivity and is a high-current conductive product, which plays the role of transmitting current and connecting electrical equipment in the circuit. In the field of transformers, copper bars are widely used to connect voltage regulating coils and transformer cabinets. [0003] The traditional copper bar cutting is carried out on the cutting platform. Copper bars used in transformers often require bevel cuts. When oblique cutting of the copper bar is required, the traditional method is to cut a reference plane on...

Problems solved by technology

Finding the reference in this way is not only a waste of material, but also the found reference surface will be out of alignment due to the thermal deformation of the material, especially after the copper bar used as the reference is heated many times, this problem is particularly prominent, and the position of the cutting line is very Difficult to find, easy to cut off, the cut copper bar is often seriously deformed, and the cutting accuracy cannot be guaranteed
