Abstract

The utility model discloses a measurement caliper of a generator stator end winding which is made of a thin plate. According to the measurement caliper disclosed by the utility model, high columns and lower columns are symmetrically distributed on two sides of a middle handle part, a groove is formed between each high column and each lower column, a distance D1 between the outer side surfaces of the high columns on the two sides approaches to the inside diameter d of the end winding, a distance D2 between the outer side surfaces of the winding columns on the winding sides approaches to the outside diameter D of the end winding, the depth h1 of the groove relative to the top surface of each low column approaches to the length L of the end winding, and approaching means a tolerance with small clearance fit between two sizes. With the adoption of the measurement caliper, through a special measurement caliper, the sizes of an inner circle and an excircle, the length size and the concentricity requirements of the stator end winding can be directly checked, so that operation is rapid and efficient, a checking result is excellent, the quality of a workpiece is ensured, and a subsequent procedure is ensured to be smoothly carried out.

Description

The measurement slide calliper rule of generator stator end winding

Technical field

The utility model relates to generator and makes field, especially a kind of measurement slide calliper rule of generator stator end winding.

Background technology

Generator unit stator as shown in Figure 1 is comprised of iron core 2 and end winding 1, and the outer diameter D of end winding 1, inner diameter d, length L equidimension all have tolerance technically, need in the production to measure and check.Existing measuring method all is to utilize tape measure to measure, and takes time and effort and measure trouble.And; overall offset as shown in Figure 1 often can occur in the coil winding process; side-play amount is δ; in this case; because the internal-and external diameter of end winding 1 does not change, thereby utilizes tape measure can not check out this defective, causes concentricity not meet the demands; affect later process, even cause scrapping of assembly.

The utility model content

The applicant is for adopting tape measure to carry out dimensional measurement in the above-mentioned existing generator unit stator manufacture process, take time and effort and the shortcoming such as poor effect, a kind of measurement slide calliper rule of generator stator end winding rational in infrastructure are provided, thus can simple and fast, accurately finish all sidedly and measure the check operation.

The technical scheme that the utility model adopts is as follows:

A kind of measurement slide calliper rule of generator stator end winding adopt the manufacturing of thin plate sheet material, and mid-handle section symmetria bilateralis is distributed with the low post of Gao Zhuyu, form groove between the low post of Gao Zhuyu; Distance B 1 between the lateral surface of both sides Gao Zhu, size approximates the inner diameter d of end winding; Distance B 2 between the medial surface of the low post in both sides, size approximates the outer diameter D of end winding; Groove is with respect to the degree of depth h1 of low capital face, and size approximates the length L of end winding; Above-mentioned " approximating " refers to exist between two sizes the tolerance of little clearance fit.

The beneficial effects of the utility model are as follows:

The utility model is by the special measurement slide calliper rule, inside and outside circle size, length dimension and concentricity requirement that can the Direct Test Stator End Winding, operation rapidly and efficiently, assay is excellent, has guaranteed the quality of workpiece, has guaranteed carrying out smoothly of subsequent handling.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

Such as Fig. 2, shown in Figure 3, measurement slide calliper rule 3 of the present utility model adopt the manufacturing of thin plate sheet material, and mid-handle section 7 symmetria bilateralis are distributed with high post 4 and low post 5, form groove 6 between high post 4 and the low post 5; Distance B 1 between the lateral surface of the high post 4 in both sides, size approximates the inner diameter d of end winding 1; Distance B 2 between the medial surface of the low post 5 in both sides, size approximates the outer diameter D of end winding 1; Groove 6 is with respect to the degree of depth h1 of low post 5 end faces, and size approximates the length L of end winding 1; Above-mentioned " approximating " refers to exist between two sizes the tolerance of little clearance fit.

When practice examining is measured, as shown in Figure 4, only need to directly snap in stator end with measuring slide calliper rule 3, end winding 1 snaps in the groove 6, whether the inside and outside circle and the length dimension that get final product Direct Test end winding 1 satisfy accuracy requirement, if insert difficulty or insert not in placely, just directly can find dimension overproof; This measuring method does not rapidly and efficiently need to adopt tape measure to carry out loaded down with trivial details measurement.And, when skew occurs coil, will inevitably cause high post 4 lateral surfaces of a side of slide calliper rule 3 and the internal diameter of iron core 2 to interfere, thereby be difficult to insert, thereby can directly find to be offset defective, guarantee carrying out smoothly of concentricity requirement and later process, can generating assembly scrap.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and in the situation of the utility model spirit, the utility model can be done any type of modification.
