Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The specific embodiment of spring assembly loading and unloading frock of the present invention, as Figure 2 to Figure 5 As shown, the frock includes a C-shaped clamping frame 9 with an opening facing the right and a stud screwed on the upper horizontal plate 91 of the clamping frame 9, which is composed of an upper horizontal plate 91, a lower horizontal plate 92, and a connecting plate. 8. The lower horizontal plate 92 constitutes the lower pressing part, and the studs are the actuators. On the lower horizontal plate 92, there is an open slot 93 for the opening of the spring assembly to pass through, which is convenient for loading and unloading. The open slot 93 is U type. The upper horizontal plate 91 is provided with a threaded hole 94 extending along the pressing direction, and the stud 8 is arranged in the threaded hole 94 to cooperate wi...

Abstract

The invention relates to a spring assembly loading and unloading tool. The tool comprises a clamping frame; a pressing mechanism is arranged on the clamping frame; the pressing mechanism comprises an upper force applying part and a lower force applying part connected with an upper spring seat and a lower spring seat of the spring assembly to apply tension or pressure on the spring of the spring assembly; and an assembly channel for enabling the upper spring seat and the lower spring seat to move to the upper force applying part and the lower force applying part along a direction perpendicular to an up-down direction and to move out from the upper force applying part and the lower force applying part is arranged on the clamping frame and / or the pressing mechanism, and thus, the loading and unloading tool can enable the spring assembly to be loaded and moved out along the direction vertical to the up-down direction. The spring is compressed or stretched through the pressing mechanism, the loading and unloading process can be completed by the force pressing mechanism, the structure is simple, and the efficiency is high.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a tool for loading and unloading a spring assembly. Background technique [0002] CTP2 series spring operating mechanism adopts modular design, simple structure, long life, high reliability, etc. It can be widely used in 12KV vacuum circuit breakers with different currents, and has a good market prospect. At present, the springs of the spring operating mechanism for indoor vacuum circuit breakers mainly adopt the form of extension spring and compression spring. When assembling the spring of the spring operating mechanism, it is necessary to ensure a certain initial pressure (pull) force, such as figure 1 The shown spring assembly that needs to be loaded and unloaded includes a spring 3, an upper spring seat and a lower spring seat. The lower spring seat includes a spring pull rod 5 that is installed in the spring from the lower end of the spring 3, and the upper spring seat includes a spri...
