Abstract
The utility model provides a transformer body pre-pressing mechanism which comprises pressing screws and a pressing screw bowl which is matched with the position of the pressing screws, wherein the pressing screws are fixed at both sides of an iron core through a clamping part, the pressing screw bowl is arranged at the upper part of a coil end ring, n disc springs are arranged between the pressing screws and the pressing screw bowl, the upper part of each disc spring is tightly contacted with each pressing screw through a pressing plate, the pressing plate is tightly contacted with each pressing screw in a mode of centering contact, that is, the contact end of each pressing screw and each pressing plate is a conical pressing head, and the contact surface of each pressing plate and each pressing screw is a concave conical pressing surface. After the transformer body pre-pressing mechanism tightly presses, the pressing screws and the disc springs always supply the pre-pressing force to a transformer body, although a material of the transformer body deforms and loses the pressing stress, because the pressure stored by the disc springs immediately supplements the pressing stress, the transformer body always keeps certain pressing force, therefore, a transformer is ensured to smoothly run without generating noises or damages; and as the pressing plates and the pressing screws are tightly contacted in the way of centering contact, the pressing screws cannot generate deviation in the pressing process, therefore, the pressing screws are smooth to press with stronger and better pressure.
Description
Technical field
The utility model relates to a kind of transformer assemble mechanism, particularly a kind of transformer body pre-compacted mechanism.
Background technology
At present to press nail that the device body is compressed what adopted through folder be the mode of pressing firmly to the device body that assembles of transformer, presses nail through manual work with defeating before promptly going into bucket, presses nail to be pressed on the pressure nail bowl on end circle top firmly.There is following weak point in this mode that compresses: transformer uses a period of time at initial stage; Operating device body is more fastening, but after after a while, the compression device body is permanent because of the time, the distortion of device stature material loses compressive stres; Make transformer lose thrust; Thereby make device body insufficient pressure and become slack, cause device that bigger noise takes place in running, when serious even can cause the device body to damage and burn out transformer.
Summary of the invention
It is a kind of through improved transformer body pre-compacted mechanism, to overcome the existing above-mentioned deficiency of prior art that the purpose of the utility model is to provide.
The technical scheme that the utility model is taked is: a kind of transformer body pre-compacted mechanism; Comprise and press nail and follow closely bowl with the pressure of pressing the nail position to cooperate; Press to follow closely to be fixed on the iron core both sides, press the nail bowl to be positioned at the top of coil-end circle, between said pressure nail and the pressure nail bowl n sheet dish spring is installed through folder; The top of dish spring clenches with pressure through pressing plate and contacts, and the value of said n is the arbitrary integer between 2～8.
Its further technical scheme is: said pressing plate adopts centering way of contact close contact with pressing nail, and promptly pressing the nail and the contact jaw of pressing plate is conical pressure head, and pressing plate is the conical pressure surface of indent with the contact-making surface of pressing nail.
Owing to take above technical scheme, a kind of transformer body pre-compacted mechanism of the utility model has following beneficial effect:
1, a kind of transformer body pre-compacted mechanism of the utility model, it presses nail n sheet dish spring to be installed with pressing between the nail bowl, compresses the back and presses nail and dish spring all the time to pre-pressing force of transformer body; When transformer after a very long time operation; Even the transformer body material deformation loses compressive stres, but because the pressure that the dish spring stores supplementary pressure immediately makes the compression device body remain certain thrust; Thereby guarantee the transformer even running, unlikely generation noise or damage.
2, because a kind of transformer body pre-compacted its pressing plate of mechanism of the utility model and pressure nail adopt centering way of contact close contact, and pressure is followed closely and in the process of pressing down, can not squinted, so press nail to press down steadily, pressure more by force better.
Below in conjunction with accompanying drawing and embodiment the technical characterictic of a kind of transformer body pre-compacted mechanism of the utility model is further described.

Embodiment:
Embodiment:
A kind of transformer body pre-compacted mechanism; Comprise and press nail 3 and follow closely bowl 6 with the pressure of pressing the nail position to cooperate; Press nail 3 to be fixed on iron core 1 both sides through folder 2; Press nail bowl 6 to be positioned at the top of coil-end circle 7, between said pressure nail 3 and the pressure nail bowl 63 dish springs 5 are installed, the top of dish spring 5 is through pressing plate 4 and pressure nail 3 close contact.
Said pressing plate 4 adopts centering way of contact close contact with pressing nail 3, and promptly pressing the nail 3 and the contact jaw of pressing plate 4 is conical pressure head 31, and pressing plate 4 is the conical pressure surface 41 of indent with the contact-making surface of pressing nail 3.
As a kind of conversion of the foregoing description, the sheet number of the dish spring of installing between said pressure nail 3 and the pressure nail bowl 6 can increase according to the different size of transformer or reduce, and its value is generally the arbitrary integer between 2～8.
