Description

Claw horn transformer quick clamping device

technical field

The utility model relates to a clamping device, in particular to a fast clamping device for a claw-type transformer.

Background technique

At present, in the verification of claw-type transformers, the clamping devices that are used more are: thread clamping method, or pliers, etc. Rotating the handle by hand when tightening the tested product is inefficient, and after the thread is locked, it is not easy to unscrew it, and it is time-consuming and laborious to remove the claw-type transformer.

Contents of the invention

The purpose of the utility model is to provide a fast clamping device for a claw-type transformer in order to reduce the clamping labor during transformer verification and improve work efficiency.

The technical scheme of the utility model is a fast clamping device for a claw-type transformer, which is composed of a quick clamp 1, an elastic push rod 2, two support frames 3 and a base 4, and the support frame 3 is composed of a support member 5 and an insulating baffle 6 components, the elastic ejector 2 has two elastic contacts 7, the two support frames 3 and the quick clamp 1 are fixed on the base 4, the insulating baffle 6 is fixed on the support 5 with countersunk screws, and the elastic ejector 2 is fixed On the main shaft of the quick clamp 1, the distance between the two supporting frames 3 is adjusted with the size of the tested product, and the distance between the two elastic contacts 7 of the elastic ejector rod 2 is equal to the distance between the two supporting frames 3. The quick clamp 1 is fixed on the neutral line between the two support frames 3 and can make the two elastic contacts 7 align with the two insulating baffles 6 on the two support frames 3, and leave the travel distance of the quick clamp 1 .

The device can reduce the labor intensity of operators, improve work efficiency, and is easy and labor-saving to operate, and is suitable for the verification of single and multiple horn-type transformers.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

In Fig. 1, the quick clamping device of the horn type transformer of the present invention is composed of a quick clamp 1, an elastic ejector rod 2, two support frames 3 and a base 4, and the support frame 3 is composed of a support member 5 and an insulating baffle 6 , the elastic ejector rod 2 has two elastic contacts 7, the two support frames 3 and the quick clamp 1 are fixed on the base 4, the insulating baffle 6 is fixed on the support member 5 with countersunk screws, and the elastic ejector rod 2 is fixed on the quick On the main shaft of the clamp 1, the distance between the two support frames 3 is adjusted according to the size of the tested product. The distance between the two elastic contacts 7 of the elastic ejector rod 2 is equal to the distance between the two support frames 3. The quick clamp equipped with the elastic ejector rod 2 The clamp 1 is fixed on the neutral line between the two support frames 3 and can make the two elastic contacts 7 align with the two insulating baffles 6 on the two support frames 3, and leave the travel distance of the quick clamp 1.

In Fig. 2, a plurality of fast clamping devices such as four claw-type transformers are fixed side by side on the base 4 of the test bench. When in use, the claw-type transformer 8 is placed between two support frames 3, and a total 7 transformers 8, the electrode copper bars at both ends of every two horn-type transformers just overlap and are sandwiched between the insulating baffle 6 and the elastic contact 7, pull the handle of the quick clamp 1 forward, and the quick clamp 1 pushes The elastic ejector rod 2 moves forward. When the elastic contact 7 at the top touches the object under test, the spring of the elastic contact 7 of the elastic ejector rod 2 is compressed. When the handle is pushed parallel to the desktop, it cannot be pushed further, and the device is Locked, the horned transformer 8 of the tested product is clamped; pull the handle of the quick clamp 1 backward, the elastic ejector rod 2 moves backward, the spring recovers, and the clawed transformer 8 of the tested product is released . When the thickness of the electrode copper bars at both ends of the claw-horn transformer 8 under test is different, the nut on the elastic mandrel 2 can be adjusted to adjust the elastic contact to achieve a suitable pressing force.

In Fig. 3, the utility model can also be placed on the support with castors, and it can be pushed to the vicinity of the table during use, and can be removed after the test is completed.

Claw-type transformer 8 is also called busbar-type transformer. The utility model can measure single or multiple claw-type transformers, which can reduce the labor intensity of operators, improve work efficiency, and is easy and labor-saving to operate.
