Embodiment Construction

[0017] An embodiment of the insulating rod pressing tooling in the present invention is as figure 1 As shown, it includes a base 12 , a guide column 7 , a press-fit pad 11 , a limit pressure head 5 , a connecting plate 2 and a hydraulic puller 1 .

[0018] The press-fit pad 11 is a plate-shaped structure, which is detachably arranged on the base 12 of the plate-shaped structure through the positioning pin 10; the guide column 7 is a stepped shaft structure, fixed on the base 12 along the thickness direction of the press-fit pad 11 and connected with the base 12 vertical. The guide column 7 includes a support section close to the base 12 and a guide section away from the base 12. The limit pressure head 5 is a plate-shaped structure and guides and moves the guide sleeve set on the guide column 7 through the guide sleeve 4 fixed thereon. paragraph. The diameter of the support section is larger than the diameter of the guide section, forming a ring platform for blocking and mat...

Abstract

The invention relates to an insulation pull rod press-fitting tool and method. The insulation pull rod press-fitting tool comprises a base, a press-fitting pad and a limiting pressure head, wherein the press-fitting pad is detachably arranged on the base, and the limiting pressure head is arranged in a guiding and moving mode in the thickness direction of the press-fitting pad. The base, the press-fitting pad and the limiting pressure head are each provided with a supporting structure used for being in force fit with an insulation rod or a connector of an insulation pull rod. The limiting pressure head has a press-fitting station and a releasing station in the guiding and moving stroke, wherein the press-fitting station is used for enabling the distance between the supporting structure on the limiting pressure head and the overall length of the insulation pull rod to be equal to the distance between the supporting structure on the base and the overall length of the insulation pull rod, and the releasing station is used for releasing the insulation pull rod. The press-fitting pad has the thickness equal to the difference between the overall length of the insulation pull rod and the single-head length. The press-fitting tool further comprises a limiting structure used for preventing the limiting pressure head moving to the press-fitting station from continuously moving to the base. According to the press-fitting tool, by means of the cooperation of the press-fitting pad and the limiting structure, the assembling precision of the insulation pull rod is ensured, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to an insulating pull rod press-fitting tool and an insulating pull rod press-fit method. Background technique [0002] The insulating pull rod is an important component used to realize power transmission and insulation isolation in the circuit breaker. Since the action part of the circuit breaker and the operating mechanism need to conduct motion accurately to ensure the precise movement of the moving contact, the assembly of the insulating pull rod Precision requirements are high. An existing insulating rod includes an insulating rod and connectors arranged at both ends of the insulating rod in the axial direction. The insulating rod and the connector are fitted with sleeves, and the overall length L of the insulating rod needs to be ensured during assembly. 2 And the length L of a single head after installing one end of the connector 1 . In the prior art, the assembly of insulating tie rods is all done manually. During the a...
