Abstract
The invention discloses an axial compaction device of a power transformer, which comprises a back pressure nail and a bottom board fixedly connected with the bottom of the back pressure nail, and the bottom plate is provided with a drum type structure. The invention takes over the advantages of simple structure and low cost of the back pressure nail, and also has the advantages of good manufacturability and strong generality.
Description
Technical field
The present invention relates to a kind of power transformer axial pressing device, specifically is a kind of improvement to anti-pressure nail used on the power transformer.
Background technology
Though along with the development power transformer axial pressing device or the member of technology presents the structure diverse trends, simple in structure, and anti-pressure nail with low cost still can be used widely.Power transformer product adopts the end outlet, and for the requirement that the low office that satisfies product puts, the surperficial roundness of metalwork requires than higher.The distance from bottom coil head end of anti-pressure nail is closer, needs the rounding processing is done in the bottom of anti-pressure nail, to have reduced the wedge angle part of metalwork.But the anti-pressure nail global formation is subject to processing technology, and its base diameter is less than normal, handles if do rounding again, must cause its bottom loading end to reduce, and it is fastened with certain negative effect.
Summary of the invention
Therefore, the present invention is directed to the above-mentioned defective of present anti-pressure nail structure, a kind of power transformer axial pressing device is provided, accept anti-pressure nail advantage simple in structure and with low cost, and good manufacturability, highly versatile.
The technical solution used in the present invention is:
Power transformer axial pressing device of the present invention comprises an anti-pressure nail and the base plate that is fixedly connected on this anti-pressure nail bottom, and this base plate has drum organization.
Substantially accepted the structure of anti-pressure nail according to the power transformer axial pressing device of technical solution of the present invention, be equivalent to install a cydariform base plate additional in the anti-pressure nail bottom, anti-pressure nail can be got the anti-pressure nail of not processing through rounding, the base plate manufacturability of drum organization is better, and increase seldom than the anti-pressure nail cost, accepted the characteristics of the universal strong of anti-pressure nail.
Above-mentioned power transformer axial pressing device, the upper bottom surface of described base plate is provided with a blind hole, and this blind hole cooperates with described anti-pressure nail bottom axis hole, and the bottom surface of anti-pressure nail cooperates with the bottom surface of blind hole.
Above-mentioned power transformer axial pressing device is welding between described anti-pressure nail and base plate.
Above-mentioned power transformer axial pressing device, described blind hole comprises the counterbore of opening portion.
Above-mentioned power transformer axial pressing device, described counterbore are vertebra shape counterbore.
Description of drawings
Fig. 1 is the base plate according to technical solution of the present invention.
Fig. 2 is the structural representation according to the power transformer axial pressing device of technical solution of the present invention.
Among the figure: 1, base plate body, 2, counterbore, 3, blind hole, 4, anti-pressure nail, 5, base plate.
Embodiment
With reference to explanation accompanying drawing 2, it shows a kind of power transformer axial pressing device, it is characterized in that the base plate 5 that it comprises an anti-pressure nail 4 and is fixedly connected on this anti-pressure nail bottom, and this base plate has drum organization.For said connection, can adopt welding or adopt the bonding of high strength glue.
Preferably, the upper bottom surface of described base plate is provided with a blind hole 3, and this blind hole cooperates with described anti-pressure nail bottom axis hole, and the bottom surface of anti-pressure nail cooperates with the bottom surface of blind hole, to increase the cooperation area of connection, the reliability of assurance connection.
Further, for welding, mention connection before and can adopt multiple mode between described anti-pressure nail and base plate, the fastness of welding is better, and welding portion can guarantee that substantially bonding strength is not less than the body portion of welded unit, satisfied normal the use.
For this reason, in order to assemble, described blind hole comprises the counterbore 2 of opening portion, and the existence of counterbore is convenient to the filling of weld material, also can guarantee the overall leveling of this hold down gag to a certain extent.
Preferably, described counterbore is a vertebra shape counterbore, more help the guiding of assembling, and formed Welding Structure is more reasonable.
Claims (5)
1. a power transformer axial pressing device is characterized in that the base plate (5) that it comprises an anti-pressure nail (4) and is fixedly connected on this anti-pressure nail bottom, and this base plate has drum organization.
2. power transformer axial pressing device according to claim 1 is characterized in that: the upper bottom surface of described base plate is provided with a blind hole (3), and this blind hole cooperates with described anti-pressure nail bottom axis hole, and the bottom surface of anti-pressure nail cooperates with the bottom surface of blind hole.
3. power transformer axial pressing device according to claim 1 and 2 is characterized in that: be welding between described anti-pressure nail and base plate.
4. power transformer axial pressing device according to claim 3 is characterized in that: described blind hole comprises the counterbore (2) of opening portion.
