Description
Technical Field
The utility model relates to an insulating pull rod production technical field of circuit breaker specifically is a simple and easy frock of manual assembly contact spring.
Background
The circuit breaker is widely used in an existing electric power system, a main component of the circuit breaker is provided with an insulating pull rod assembly, the insulating pull rod assembly comprises a guide shaft connected with a moving contact of the vacuum arc extinguish chamber, a contact spring is sleeved on the guide shaft, a pressing sleeve is arranged at the top end of the contact spring and is connected with the guide shaft through a pin shaft, the pressing sleeve compresses the contact spring during assembly to enable the spring to have initial pre-pressure, manual assembly is inconvenient to operate due to the fact that the pre-pressure is large, the contact spring is difficult to compress and then pin shaft insertion is conducted, time and labor are wasted during operation of workers, and working efficiency is low.
Disclosure of Invention
The utility model discloses a main objective is in order to solve above-mentioned present manual assembly contact spring and waste time and energy, and the problem that work efficiency is low provides a simple and easy frock of manual assembly contact spring.
The utility model has the following concrete scheme: the simple tool comprises a fixed frame, wherein a supporting cross beam is arranged in the middle of the inside of the fixed frame, a jacking mechanism is installed below the supporting cross beam, a vacuum arc extinguish chamber is placed on the supporting cross beam, a positioning hole is formed in the supporting cross beam and used for inserting a static contact of the vacuum arc extinguish chamber, the top output end of the jacking mechanism faces the positioning hole, a positioning block is arranged at the top end of the inside of the fixed frame, and the positioning block is used for blocking a pressing sleeve of a contact spring.
The locating piece is arranged with the locating hole is coaxial.
Climbing mechanism adopts jack or cylinder or hydro-cylinder or electronic jar.
Locating piece up end and fixed frame fixed connection, lower terminal surface are equipped with and press the spacing face of cover, press the spacing face middle part of cover to be equipped with and upwards stretch into the inside hole of stepping down of locating piece, the hole diameter of stepping down is less than and presses the cover and be greater than insulating draw bar assembly's guiding axle.
The working principle of the utility model is as follows: the vacuum arc-extinguishing chamber is placed in a fixed frame, a static contact is inserted into a positioning hole of a supporting beam downwards, then a contact spring and a pressing sleeve are installed on a guide shaft, the pressing sleeve is manually rotated to enable a pin hole of the pressing sleeve and a pin hole of the guide shaft to be in the same direction, then a jacking mechanism is operated to jack the static contact of the vacuum arc-extinguishing chamber upwards, the pressing sleeve is limited by the positioning block in the process that the vacuum arc-extinguishing chamber jacks upwards, the guide shaft continues to move upwards, when the pin hole of the guide shaft is aligned with the pin hole of the pressing sleeve, jacking is stopped, finally a pin shaft is inserted, and after the pin shaft is inserted in place, the jacking mechanism is loosened to enable the contact spring to reset naturally, so that assembly is completed.
Compared with the prior art, the utility model has the following advantages: the assembly operation is more convenient, and the working efficiency is improved.
Drawings
Fig. 1 is a schematic view of the initial state of the contact spring of the present invention;
fig. 2 is a schematic view of the contact spring of the present invention in a compressed state during assembly;
in the figure: the method comprises the following steps of 1-fixing a frame, 2-a jacking mechanism, 3-a supporting beam, 4-a vacuum arc extinguish chamber, 5-a guide shaft, 6-a contact spring, 7-a pressing sleeve, 8-a positioning block and 9-a pin hole.
Detailed Description
Referring to fig. 1-2, the present embodiment is a simple tool for manually assembling a contact spring, and the tool includes a fixed frame 1, a supporting beam 3 is disposed at a middle portion in the fixed frame 1, a jacking mechanism 2 is mounted below the supporting beam 3, the supporting beam 3 is used for placing a vacuum arc extinguish chamber 4, a positioning hole is disposed on the supporting beam 3, the positioning hole is used for inserting a static contact of the vacuum arc extinguish chamber 4, a top output end of the jacking mechanism 2 faces the positioning hole, a positioning block 8 is disposed at a top end in the fixed frame 1, and the positioning block 8 is used for blocking a pressing sleeve 7 of the contact spring 6.
The positioning block 8 and the positioning hole are arranged coaxially in the embodiment.
In this embodiment, the jacking mechanism 2 is a jack, an air cylinder, an oil cylinder or an electric cylinder.
This embodiment 8 up end of locating piece and fixed frame 1 fixed connection, the terminal surface is equipped with the spacing face of pressure cover down, presses the spacing face middle part of cover to be equipped with and upwards stretches into the inside hole of stepping down of locating piece 8, and the hole diameter of stepping down is less than and presses cover 7 and be greater than guiding axle 5.
When the vacuum arc-extinguishing chamber 4 is jacked upwards by the jacking mechanism 2, the guide shaft 5, the contact spring 6 and the pressing sleeve 7 are synchronously jacked upwards, the pressing sleeve 7 is firstly limited and stopped by the positioning plate 8, the guide shaft 5 continues to be jacked upwards, the pin hole of the guide shaft 5 gradually rises until the jacking mechanism 2 stops when being aligned with the pin hole of the pressing sleeve 7, and the pin shaft can be inserted at the moment.
