Description
Technical field
The utility model is related to the making frock of parts in transformer, relates in particular to the system of transformer yoke insulation
Make frock.
Background technology
Transformer yoke insulation is important insulating part required when transformer body is assembled.Core insulation is generally by some length
The cross-over block of cube is uniformly pasted on insulating board circle and constitutes, and as shown in Figure 6 and Figure 7, generally to make in every transformer
With more than ten even tens core insulations for differing in size.Core insulation is arranged on the upper and lower ends of transformer coil, plays
Oil Guide, mechanical support, the effect for keeping insulation distance.During due to transformer assembling, it is desirable to each cushion block on core insulation with
Coil stay and general assembly stay align, so the decile to cushion block on core insulation on cardboard circle（I.e. cushion block is in cardboard circle
On circumferential position accuracy）Propose requirement very high.
At present, the preparation method of core insulation is as follows：
1st, corresponding decile mould 12, the insulating board that will be made are selected according to core insulation decile and cushion block width requirement
Circle 9（Usual 1-3 millimeters thicks）Lie on decile mould 12, center of circle position is determined by the internal diameter of cardboard circle 9 and three pieces of Steel Rulers 11
Put, rule one by one on cardboard circle 9, as shown in Figure 8.
2nd, cushion block viscous 10 is connected on cardboard circle 9 according to scribing position.
3rd, the spacing of cushion block 10, the big cushion block 10 of adjustment deviation are checked one by one with tape measure.
4th, the core insulation that will be made is removed.
Existing this preparation method exists following not enough：
1st, need to rule one by one in manufacturing process, workload is big and speed is slow.
2nd, in scratching process, cardboard circle is easily subjected to displacement and causes line inaccurate, so as to influence cushion block on cardboard circle
Circumferential position accuracy.
3rd, there is one fixed width in the line marked with wax crayon in itself, and cushion block is pasted accordingly, can also influence cushion block on cardboard circle
Circumferential position accuracy.
The content of the invention
The purpose of this utility model is to provide a kind of making frock of transformer yoke insulation, exhausted to improve transformer yoke
The manufacturing speed and quality of edge.
The making frock of transformer yoke insulation described in the utility model, is made up of chassis and equi-index plate, and chassis includes bottom
Plate and newel, newel are vertically fixed on the center of base plate, are marked with least along newel radial direction in plate upper surface
Three groups of scales；Equi-index plate is made up of contiguous block, connection ring and at least eight skeletons, and contiguous block is located at connection ring center, skeleton
Two ends side does not weld with contiguous block and connection ring, and skeleton is eccentric and is evenly distributed between contiguous block and connection ring, contiguous block
Center is vertically welded with axle sleeve, the axle sleeve be sleeved on the newel with newel rotatable engagement, equi-index plate is supported on bottom
On the base plate of disk, lock-screw is radially connected with axle sleeve.
The scale mark of plate upper surface distance of the scale to base plate center.
The cross section of the skeleton is square.
Before making core insulation, the cardboard circle of annular and the cushion block of rectangle are prepared first, first by equi-index plate from chassis
Take out, cardboard circle is lain on base plate, determine that cardboard circle exists by the scale on cardboard circle internal diameter or outside dimension and base plate
Position on base plate, makes the center of circle of cardboard circle and base plate center superposition.
Equi-index plate is sleeved on the newel on chassis by its axle sleeve, equi-index plate is located on chassis, and by cardboard circle
It is pressed between equi-index plate and base plate, lock-screw is screwed, prevents from being relatively rotated between equi-index plate and chassis.
Cushion block is pasted onto on cardboard circle as guiding ruler using the skeleton of equi-index plate.
After equi-index plate is taken out from chassis, core insulation is removed.
The utility model is used for the making of transformer yoke insulation, aids in filling as a result of equi-index plate and chassis etc.
Put, on cardboard circle paste cushion block when, position of the cushion block on cardboard circle is directly determined by the skeleton on equi-index plate, only need by
Cushion block edge nestles up skeleton and is pasted onto on cardboard circle.Because position of the cushion block on cardboard circle is by the skeleton on equi-index plate
To ensure, only need to be when equi-index plate be made, circumferential position accuracy of the strict control skeleton on equi-index plate, you can effectively ensure
Circumferential position accuracy of the cushion block on cardboard circle.So as to eliminate cumbersome crossed process, by core insulation manufacturing process not
Controllable accidental error is converted into controllable systematic error, reduces the competency profiling to core insulation producer, improves
The manufacturing speed and operating efficiency of core insulation, it is ensured that the stability of product quality.

Specific embodiment
In order to the technical solution of the utility model is explained further, come to carry out the utility model in detail below in conjunction with the accompanying drawings
Illustrate.
As shown in Figure 1, Figure 2 and Figure 3, the making frock of transformer yoke insulation is made up of chassis and equi-index plate, chassis bag
The base plate 1 and newel 2 of circle are included, newel 2 is vertically fixed on the center of base plate 1, in the upper surface of base plate 1 along newel 2 half
Footpath bearing mark has four groups of scales 3, four groups of scales 3 respectively positioned at two of chassis it is orthogonal diametrically, every group of scale 3 is marked
The distance of the scale 3 to the center of base plate 1 is remembered.
As shown in Figure 4 and Figure 5, the equi-index plate is made up of contiguous block 8, connection ring 4 and 20 skeletons 5, contiguous block 8
In the center of connection ring 4, the cross section of skeleton 5 is square, and its two ends side does not weld with contiguous block 8 and connection ring 4, and skeleton 5
Bias is evenly distributed between contiguous block 8 and connection ring 4, i.e., skeleton 5 is evenly arranged on equi-index plate, and each skeleton 5
With a diameter parallel of equi-index plate and be separated by an identical distance.The center of contiguous block 8 is vertically welded with axle sleeve 7, the axle
