Problems solved by technology

[0002] In the past, when the flange and the insulator were glued together, due to the long insulator, it was not easy to ensure the coaxiality of the two flange holes, but there was no special tool, so it could only be operated by experience, and the probability of errors was relatively high.

Embodiment Construction

[0008] As shown in the figure, the present invention consists of two pressing plates 1, 4, pull rod 2, and nut 3.

[0009] Two pressure plates 1,4 are identical in shape and structure, both are semicircular, and have holes 5,6 respectively on the same horizontal plane on the two pressure plates 1,4, and pull rod 2 passes through in these holes 5,6.

[0010] Several holes 7 are distributed on the pressure plates 1 and 4, and the positions of the holes 7 are at the same position as the mounting holes of the flange.

[0011] When the flange is glued to the insulator, the pressure plates 1 and 4 are respectively pressed on the outside of the two flanges, the holes 7 on the pressure plates 1 and 4 are bolted to the corresponding flange mounting holes with bolts 8, and then the pull rod 2 is used to pass through the insulator Fasten with nuts 3 on the outside of the pressure plates 1 and 4 to ensure that the two pressure plates 1 and 4 are coaxial. In this way, through the coaxialit...

Abstract

The invention discloses a concentricity jig of a flange mounting hole. Two pressure plates with the identified structure are provided with holes at the same water level. A pulling rod passes through the holes and is fastened by a bolt. The concentricity jig of the flange mounting hole is characterized in that the pressure plates are semicircular, a plurality of holes are arranged on the pressure plates; the holes on the pressure plates are in the same position with the flange mounting holes. The structure has the advantages that the jig adopts the semicircular pressure plates and corresponding positions of the pressure plates are provided with holes matching with the flange mounting holes. When the flange is connected with insulator gel, the two pressure plates are compressed tightly at two ends and are fastened in the same water level by the pulling rod. The holes on the pressure plates are respectively corresponding to the flange mounting holes and are fastened by bolts. When the connection between the flange and the insulator adhesive is finished, the jig can be demounted. The device can install flanges effectively and rapidly, and the coaxial performance is guaranteed absolutely.

Description

technical field [0001] The invention relates to a flange installation hole coaxiality fixture, in particular to a flange installation hole coaxiality fixture which is convenient for quick positioning and installation. Background technique [0002] In the past, when the flange was glued to the insulator, due to the long insulator, it was not easy to ensure the coaxiality of the two flange holes, but without special tools, it could only be operated by experience, and the probability of errors was relatively high. Contents of the invention [0003] The main task of the present invention is to provide a flange mounting hole coaxiality jig, in particular to a flange mounting hole coaxiality jig that is convenient for quick positioning and installation. [0004] In order to solve the above technical problems, a flange mounting hole coaxiality fixture of the present invention consists of two pressure plates with the same structure having holes on the same horizontal plane, and th...
