Abstract

The utility model provides a mini breaker testing clamp and belongs to the technical field of machinery. The mini breaker testing clamp solves the problem that a conventional clamp is low in efficiency and can not automatically clamp products. The mini breaker testing clamp comprises a base plate, a fixed clamping plate arranged on the base plate and a movable clamping plate oppositely arranged with the fixed clamping plate, wherein the fixed clamping plate and the movable clamping plate are made of epoxy resin material. A mini breaker is positioned between the fixed clamping plate and the movable clamping plate, and the base plate is also provided with a driving structure which drives the movable clamping plate to laterally move to the fixed clamping plate. A power supply structure powering on the mini breaker is arranged between the fixed clamping plate and the movable clamping plate. The mini breaker testing clamp automatically clamps and loosens the breaker during a test process, and is convenient and flexible for use, and improves work efficiency.

Description

Small-size breaker testing fixture

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of miniature circuit breaker testing apparatus, particularly a kind of small-size breaker testing fixture.

Background technology

Miniature circuit breaker is a kind of application low-voltage controling appliance very widely, in the production run of miniature circuit breaker, need to carry out the test of time delay release property to product, existing domestic low-voltage electrical apparatus manufacturer, when carrying out delay performance verification, still adopts manual mode mostly, by workman, product is fixed on the test fixture of checking table, after fixing, test, fixture cannot Automatic-clamping product, and action is complicated, inefficiency.

Summary of the invention

The purpose of this utility model is to have the problems referred to above for existing technology, proposed a kind of can Automatic-clamping in test process and unclamp the small-size breaker testing fixture of product.

The purpose of this utility model can realize by following technical proposal:

Small-size breaker testing fixture, the moving clamping plate that comprise base plate, are located at the clamp plate on base plate and are oppositely arranged with clamp plate, miniature circuit breaker is between described clamp plate and moving clamping plate, it is characterized in that, on described base plate, also have and drive moving clamping plate to the drives structure of clamp plate transverse shifting, between described clamp plate and moving clamping plate, be provided with the electric power-feeding structure of conducting miniature circuit breaker.

In above-mentioned small-size breaker testing fixture, described drives structure is for to be laterally fixed at the cylinder on base plate with " L " shape support, and above-mentioned moving clamping plate are located on the piston rod of this cylinder, and described cylinder is connected to foot valve and by its control.

In above-mentioned small-size breaker testing fixture, described electric power-feeding structure comprises a contact and No. two contacts of being located on moving clamping plate be located on clamp plate, and described a contact and No. two contacts are all wired to constant current source.

In above-mentioned small-size breaker testing fixture, described clamp plate and moving clamping plate are made by epoxide resin material.

Compared with prior art, this small-size breaker testing fixture has the following advantages: adopt foot valve control cylinder to drive moving clamping plate, can be in test process Automatic-clamping and unclamp product, flexible and convenient to use, improved work efficiency, result of use is good.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model releasing orientation.

Fig. 2 is the structural representation of the utility model clamped condition.

In figure, 1, base plate; 2, clamp plate; 3, moving clamping plate; 4, cylinder; 5, " L " shape support; 6, foot valve; 7, constant current source; 8, miniature circuit breaker; 21, a contact; 31, No. two contacts.

Embodiment

Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

Small-size breaker testing fixture as shown in Figure 1 and Figure 2, the moving clamping plate 3 that comprise base plate 1, are located at the clamp plate 2 on base plate 1 and are oppositely arranged with clamp plate 2, miniature circuit breaker 8 is between described clamp plate 2 and moving clamping plate 3, it is characterized in that, on described base plate 1, also have and drive moving clamping plate 3 to the drives structure of clamp plate 2 transverse shiftings, between described clamp plate 2 and moving clamping plate 3, be provided with the electric power-feeding structure of conducting miniature circuit breaker 8.

Concrete, the cylinder 4 of described drives structure for being laterally fixed on base plate 1 with " L " shape support 5, moving clamping plate 3 are located on the piston rod of this cylinder 4, and cylinder 4 is connected to foot valve 6 and by its control.

Concrete, described electric power-feeding structure comprises a contact 21 and No. two contacts 31 of being located on moving clamping plate 3 be located on clamp plate 2, described a contact 21 and No. two contacts 31 are all wired to constant current source 7.

Concrete, described clamp plate 2 is made by epoxide resin material with moving clamping plate 3.

During work, it is middle with moving clamping plate 3 that workman is positioned over clamp plate 2 by miniature circuit breaker 8, pin steps on foot valve 6 stretches out cylinder 4, make contact 21 and No. two contacts 31 start test respectively with after the binding post close contact of miniature circuit breaker 8, after being completed, pin steps on foot valve 6 and makes cylinder 4 retractions again, thereby miniature circuit breaker 8 is unclamped from fixture.
