Abstract
The invention relates to a method for quickly positioning a special-shaped flange plate of a transformer, and belongs to the technical field of transformer manufacturing. The technical scheme of the invention is as follows: the special-shaped flange plate is provided with a boss which is cut at the end point of the long shaft or the short shaft of the oval flange plate for marking during blanking, the mark is used as the position of a reference marking positioning hole during machining and punching, and a welding team is aligned and positioned for spot mounting when spot mounting workpieces. The invention has the beneficial effects that: need not additionally to increase manpower and materials, can do high-efficient, swift, accurate, the operator intensity of labour that significantly reduces, improve work efficiency, improve product quality.
Description
Technical Field
The invention relates to a method for quickly positioning a special-shaped flange plate of a transformer, and belongs to the technical field of transformer manufacturing.
Background
The lower flange of the lifting seat arranged above the tank cover of the oil tank bending structure of the oil-immersed power transformer is mainly of an external circular internal oval structure (as shown in figure 1), and each transformer product is provided with at least three or more lifting seat flange plates (hereinafter, oval flange plates) with the structure (as shown in figure 2). After the blanking process is carried out by numerical control programming cutting blanking according to the drawing size, the machining process is not easy to find the highest point position of the long axis or the short axis when the flange plate is machined, namely the flange plate is not easy to position and mark, the flange plate hole is positioned and has deviation after machining, and the problem is more obvious when the outer diameter size of the flange plate is larger; the flange plate and the rising seat wall are very difficult to point-mount by welding teams, and cannot be aligned, so that the point-mount workpiece is large in workload, long in product period and difficult to guarantee product quality.
Disclosure of Invention
The invention aims to provide a method for quickly positioning a special-shaped flange plate of a transformer, which does not need additional manpower and material resources, can be efficiently, quickly and accurately carried out, greatly reduces the labor intensity of operators, improves the working efficiency, improves the product quality and effectively solves the problems in the background technology.
The technical scheme of the invention is as follows: a method for quickly positioning a special-shaped flange plate of a transformer comprises the following steps: the special-shaped flange plate is provided with a boss which is cut at the end point of the long shaft or the short shaft of the oval flange plate for marking during blanking, the mark is used as the position of a reference marking positioning hole during machining and punching, and a welding team is aligned and positioned for spot mounting when spot mounting workpieces.
The special-shaped flange plate is characterized in that the outer ring is a regular circle, and the inner ring is an ellipse.
The cutting of the lug boss is realized by adding two columnar lug bosses with semicircular sections at two end points of the long axis of the ellipse in the flange plate, and the radius of the semicircle is 5 mm.
The invention has the beneficial effects that: need not additionally to increase manpower and materials, can do high-efficient, swift, accurate, the operator intensity of labour that significantly reduces, improve work efficiency, improve product quality.

Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments, which are preferred embodiments of the present invention. It is to be understood that the described embodiments are merely a subset of the embodiments of the invention, and not all embodiments; it should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A method for quickly positioning a special-shaped flange plate of a transformer comprises the following steps: the special-shaped flange plate is provided with a boss which is cut at the end point of the long shaft or the short shaft of the oval flange plate for marking during blanking, the mark is used as the position of a reference marking positioning hole during machining and punching, and a welding team is aligned and positioned for spot mounting when spot mounting workpieces.
The special-shaped flange plate is characterized in that the outer ring is a regular circle, and the inner ring is an ellipse.
The step of cutting the lug boss is that two columnar lug bosses 1 with semicircular sections are additionally arranged at two end points of the long axis of the ellipse in the flange plate, and the radius of the semicircle is 5 mm.
When the special-shaped flange plate is machined, programming is needed before blanking for fast and accurate positioning machining and welding, and during programming, a mark is marked at a special-shaped part so as to facilitate subsequent machining and welding. Since the machining of the flange plate of the method not only includes the steps of drilling the flange plate, but also lathing the surface and the outer circle of the flange plate, the method of marking the surface of the flange plate is not suitable for the workpiece.
In practical application, when the elliptical flange plate is blanked, a columnar boss with a semicircular section is cut at the end point of the long shaft or the short shaft of the ellipse, the semicircular radius is 5mm to be marked, the mark is used as the position of a reference marking positioning hole when the elliptical flange plate is machined and punched, a welding team is very easy to align and position to perform spot assembly when a workpiece is spot-assembled, and the working efficiency and the product quality are greatly improved.
