Abstract

The invention discloses a coaxiality control tool and a coaxiality control method. The coaxiality control tool comprises a base and a screw rod. A first sliding block and a tensioning device are arranged on the base, a second sliding block is arranged on the first sliding block, and baffles are arranged on the left side and the right side of the second sliding block respectively. A stand column is arranged on the second sliding block, and an accessory limiting and clamping device and a ceramic part limiting and clamping device are arranged on the stand column. A second baffle is arranged on one side of the base, and one end of the screw rod penetrates through the second baffle and is connected with the first sliding block. The first sliding block moves on the base in a left-and-right and back-and-forth mode through the screw rod and is firmly fixed on the base through the tensioning device after moving to a proper position. The coaxiality control tool is used for controlling the vibration adhesive binding geometric tolerance of a bar type ceramic composite insulator so that the coaxiality of an adhesive binding ceramic part and an accessory can be 1mm and the coaxiality of the upper accessory and the lower accessory can be 0.5mm. Following forming process quality can be ensured, core shift of a whole product will not exist, the insulation thickness is even, the electromechanical property of the product is greatly improved, and long-term operation of the product can be stable and reliable.

Description

technical field [0001] The invention relates to the field of vibrating glue-mounting of rod-type porcelain composite insulators, in particular to a coaxiality control tool and a method for controlling the geometric tolerance of the rod-type porcelain composite insulator vibration glue-fitting by using the coaxiality control tooling. Porcelain insulator geometric tolerance control tooling mainly invents a series of tooling for effective control of geometric tolerance during the vibrating glue-fitting process of rod-type porcelain composite insulators for electrified railways. Background technique [0002] Rod-type porcelain composite insulators for electrified railways are a new type of insulators. At present, rod-type porcelain insulators and rod-type composite insulators are widely used in electrified railway catenary arms. However, the surface of rod-type porcelain insulators in operation is easy to adhere to dirt, and external flashover may occur when the weather conditio...
