Abstract
The invention relates to a plastic shell type breaker link mechanism main spring installation tool and a using method thereof. The plastic shell type breaker link mechanism main spring installation tool is characterized by being a plier, one lateral arm of a clamping article positioned on the front end of the plier is provided with a pointed wedge shape with the front part convenient to be inserted into gaps between every two rings of the installed breaker link mechanism main spring, and the front end of a lateral arm of the pointed wedge shape is provided with a U-shaped rabbet, and the difference of the length of the other lateral arm of the plier and the length of the one lateral arm is slightly more than the sum of the excircle radius of the installed breaker link mechanism main spring and the excircle diameter of a lifting root segment of the installed breaker link mechanism main spring. Because the front end of one lateral arm of the plier is provided with the pointed wedge shape capable of being inserted into gaps between every two rings of the installed breaker link mechanism main spring, the front end of the pointed wedge shape is provided with the U-shaped rabbet, and the length of the other lateral arm is shorter than that of a lateral arm of the pointed wedge shape, the invention simplifies the disassembly and the assembly of the plastic shell type breaker link mechanism main spring, thereby lowering the labor intensity, enhancing the work efficiency and ensuring the production security; and in addition, the invention damages no structural members of the plastic shell type breaker link mechanism main spring, thereby saving materials and reducing the product cost.
Description
Technical field
The invention belongs to a kind of moulded case circuit breaker erecting tools, particularly relate to a kind of plastic shell type breaker link mechanism main spring installation tool and using method.
Background technology
Present known 400A and above big housing mold cased circuit breaker are because of the needs of linkage, and often She Ji main spring elastic pulling force is very big, have caused main spring installment work labour intensity big.Traditional installation method is to adorn a joint hinge on the spring, and this joint hinge has upper and lower two earrings to link to each other, and pounds seal in the middle of two earrings.Wear axle on earrings hole during mounting spring on joint hinge, axle is levered up, in the earrings below when the earrings hole below the joint hinge is higher than lever, axle being penetrated with crowbar.After spring is installed top earrings is removed along pounding seal.So traditional not only loaded down with trivial details, waste material of assembly method, and difficult more when needs dismounting main spring, the spring of pulling down also can not be reused.
Summary of the invention
The present invention provides a kind of assembly method simple for solving the technical problem that exists in the known technology, also reusable plastic shell type breaker link mechanism main spring installation tool of the spring of pulling down and using method.
The technical scheme that the present invention takes for plastic shell type breaker link mechanism main spring installation tool for the technical problem that exists in the solution known technology is: it is an a pair of tongs; Side arm at described pliers front end gripping objects is that the glut shape that is mounted gap between each circle of breaker link mechanism main spring is convenient to insert in a front portion, and at the front end of this glut shape side arm one U type notch is arranged; The length of another side arm of described pliers less than an aforementioned side arm and with the difference of the length of an aforementioned side arm be to be slightly larger than the joint hinge root outside diameter sum that is mounted on breaker link mechanism main spring exradius and this main spring.
The present invention for the technical scheme that solves the technical problem that exists in the known technology and take for the using method of plastic shell type breaker link mechanism main spring installation tool is: at first the U type notch of the front end of glut shape side arm is aimed at joint hinge, be inserted in main spring the 2nd, between 3 circles, another side arm is pressed on the lever of breaker link mechanism, firmly clamp pliers then, when the earrings hole on the main spring joint hinge is exposed to the lever upper surface, axle is penetrated in the earrings hole on the joint hinge, again axle is put into the groove of reserving on the lever, pull down pliers at last, main spring installs.
Advantage and good effect that the present invention has are: it can be applied to the installation of mechanism's main spring of the circuit breaker of multiple housing similar structures in 400A and the above series.The present invention is to insert the glut shape among the gap between each circle of breaker link mechanism main spring owing to having adopted the side arm front end at pliers, and the U-lag mouth of its front end can escape the main spring joint hinge again; And the opposite side arm lengths is shorter than the technical scheme that front end is a glut shape side arm length.It can not only realize the dismounting of main spring easily, make assembling be tending towards simple, reduce working strength of workers greatly, increase work efficiency greatly, ensure the fail safe of producing, and do not destroy any structure spare on the main spring, the spring of pulling down can be reused, economical with materials reduces product cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, a side arm 3 of gripping objects is a glut shape on pliers 1, and at the front end of this side arm 3 a U type notch is arranged; The length of another side arm 2 of pliers 1 less than side arm 3 and with the difference of the length of side arm 3 be to be slightly larger than the joint hinge root outside diameter sum that is mounted on breaker link mechanism main spring exradius and this main spring.
Using method of the present invention is as follows: at first the U type notch of side arm 3 band glut shape front ends is aimed at joint hinge, be inserted in main spring the 2nd, between 3 circles, another side arm 2 is pressed on the lever of breaker link mechanism, firmly clamps pliers 1 then, when the earrings hole on the main spring joint hinge is exposed to the lever upper surface, axle is penetrated in the earrings hole on the joint hinge, axle is put into the groove of reserving on the lever again, pulled down pliers 1 at last, main spring installs.Same this instrument also can be pulled down main spring easily, and spring is reusable.
