CN101975542B - Method for measuring coaxiality of flange screw holes on both ends of porcelain housing - Google Patents

Abstract

The present invention relates to a method for measuring coaxiality of flange screw holes on both ends of a porcelain housing, which comprises the following steps: a. preparing four identical screws with screw rods, wherein the diameter of the threaded parts of the screws tallies with that of the screw holes of flanges; b. putting the porcelain housing horizontally, and respectively screwing the two screws on the two flanges, wherein the hole on a first side can be any of two, and the screw hole on the other side is corresponding to the first side; c. putting a level gauge on the two screw rods on the first side, adjusting the porcelain housing, and leveling and fixing the level gauge; d. and putting the level gauge on the screw rods on the other side, wherein if the level gauge is horizontal, the flange screw holes on both ends of the porcelain housing are proved to be coaxial, or else, the flange screw holes on both ends of the porcelain housing are proved to be not coaxial. The method has the advantages of high accuracy and convenient operation.

Description

A kind of whether coaxial method of insulator two ends flange screw of measuring

Technical field

Whether coaxial technical field under the present invention relates to the electric porcelain production technical field, specifically relate to a kind of insulator two ends flange screw method of measuring.

Background technology

The insulator in the middle of insulator has and the flange at two ends, two flanges have same number and corresponding screw; Technical requirement, the screw of two side flange correspondences must be on axis, claim coaxially again, and promptly the center line of Dui Ying two screws must be that a line is only qualified product, otherwise is exactly waste product.In the prior art, what whether the center line of measuring two screws was that straight line adopts is the suspension wire method, because the general length of insulator is 2-3 rice, it is bigger to measure time error, even can not distinguish, and influences the identification of product quality.

Summary of the invention

Whether coaxial purpose of the present invention is exactly at above-mentioned shortcoming, provide a kind of more accurate, easy to operate measurement insulator two ends flange screw method.

Whether coaxial the technical solution used in the present invention is: measure insulator two ends flange screw method, may further comprise the steps:

A, four identical screws of preparation with screw rod, the diameter of the band silk part of described screw and the screw of flange coincide;

B, with the insulator horizontal positioned, two the above-mentioned screws of on these two flanges, respectively screwing on, the hole of first side can be chosen wherein two wantonly, the screw of opposite side is corresponding with first side;

C, surveyor's staff is placed on two screw rods of first side, adjust insulator, make surveyor's staff level, fixing;

D, surveyor's staff is placed on the screw rod of opposite side, if the surveyor's staff level proves that insulator two ends flange screw is coaxial, otherwise disalignment.

The invention has the beneficial effects as follows:, have whether coaxial more accurate, easy to operate advantage of the insulator of measurement two ends flange screw because the present invention taked above technical scheme.

Description of drawings

Fig. 1 is the synoptic diagram of step c of the present invention.

Wherein: 1, screw rod 2, leveling ruler level

Embodiment

The invention will be further described below in conjunction with accompanying drawing.

Measure the whether coaxial method of insulator two ends flange screw, may further comprise the steps:

A, four identical screws of preparation with screw rod, the diameter of the band silk part of described screw and the screw of flange coincide; Such screw has screw rod can place surveyor's staff in following step c and d, the diameter of described screw and the screw of flange coincide and make screw not have unnecessary activity in screw, reduce error.

B, with the insulator horizontal positioned, two the above-mentioned screws of on these two flanges, respectively screwing on, the hole of first side can be chosen wherein two wantonly, the screw of opposite side is corresponding with first side, is chosen in two screws on the diameter as optimal technical scheme;

C, as shown in the figure places surveyor's staff 2 on two screw rods 1 of first side, adjusts insulator, and rolling get final product, makes the surveyor's staff level, fixes;

D, surveyor's staff is placed on the screw rod of opposite side, if the surveyor's staff level proves that insulator two ends flange screw is coaxial, otherwise disalignment.

Claims (1)

1. measure the whether coaxial method of insulator two ends flange screw, may further comprise the steps:
