Description

Dry-type transformer tap welding frock

Technical Field

The utility model relates to a dry-type transformer field, specific theory has related to a dry-type transformer tap welding frock.

Background

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC machines and other places, and simply, dry-type transformers refer to transformers in which iron cores and windings are not immersed in insulating oil. Need carry out tap welding process in transformer production process, however, do not have special dry-type transformer tap welding frock at present, often need handheld copper nut to weld in the welding process, damage welding personnel's hand easily.

In order to solve the above problems, people are always seeking an ideal technical solution.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a dry-type transformer tap welding frock to prior art's not enough.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is:

the utility model provides a dry-type transformer tap welding frock, includes mould base, sets up stand on the base, slidable mounting in the holder on the stand, sets up the positioning mechanism in the holder lateral part, and the holder is used for centre gripping copper nut, and the mould base is used for placing the dry-type transformer mould.

Based on the above, the clamping piece comprises a clamping groove, a threaded hole is formed in the upper side of the clamping groove, and a first positioning nut is installed in the threaded hole.

Based on the above, set up vertical through-hole on the holder, in this vertical through-hole was worn to locate by the stand, positioning mechanism included the screw hole that is located vertical through-hole one side and set up the second set nut in this screw hole.

Based on the above, the base includes three first stabilizer blade and clamp plate, and on the lower extreme of stand was fixed in the clamp plate, the one end of three first stabilizer blade was crossing in a point and set up the connecting rod at this point and connect the clamp plate, and the height of connecting rod equals the height of mould base, and during the welding, the clamp plate was arranged in on the mould base.

Based on the above, the mold base comprises the supporting plate and four second supporting legs arranged at the bottom of the supporting plate, the height of each second supporting leg is larger than the thickness of the corresponding first supporting leg, and the gap between any two adjacent second supporting legs is larger than the width of the corresponding first supporting leg.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a dry-type transformer tap welding frock, this dry-type transformer tap welding frock can be used for dry-type transformer lead welding process, effectively avoids the injured probability of welding process workman, improves welding efficiency. In the specific use process, the dry-type transformer to be welded is placed on the mold base, the copper nut is fixed on the clamping piece, the clamping piece is adjusted to be suitable for the height, and then welding is carried out.

Fig. 2 is a schematic structural view of the base support leg of the present invention.

In the figure: 1. a first leg; 2. a second leg; 3. a connecting rod; 4. pressing a plate; 5. a support plate; 6. a column; 7. a first positioning nut; 8. a second positioning nut; 9. a clamping member; 10. copper nut.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-2, a dry-type transformer tap welding fixture comprises a mold base, a column 6 arranged on the base, a clamping member 9 slidably mounted on the column 6, and a positioning mechanism arranged on the side of the clamping member 9, wherein the clamping member 9 is used for clamping a copper nut 10, and the mold base is used for placing a dry-type transformer mold.

This dry-type transformer tap welding frock can be used for dry-type transformer lead welding process, effectively avoids the injured probability of welding process workman, improves welding efficiency. In the specific use process, the dry-type transformer to be welded is placed on the mold base, the copper nut is fixed on the clamping piece, the clamping piece is adjusted to be suitable for the height, and then welding is carried out.

Further, the clamping piece 9 comprises a clamping groove, a threaded hole is formed in the upper side of the clamping groove, and a first positioning nut 7 is installed in the threaded hole. In the use, go into the draw-in groove with the one end card of copper nut, the tight copper nut in top of first set nut of screwing is fixed, then welds again, and the welding is accomplished the back, loosens first set nut to take off the copper nut.

Further, set up vertical through-hole on the holder 9, in this vertical through-hole was worn to locate by stand 6 to the holder can reciprocate along the stand, and positioning mechanism is including the screw hole that is located vertical through-hole one side and setting up the second set nut 8 in this screw hole. After moving the clamping piece to a proper height, screwing a second positioning nut to jack the upright post for positioning.

Further, the base includes three first stabilizer blade 1 and clamp plate 4, and on the lower extreme of stand 6 was fixed in clamp plate 4, the one end of three first stabilizer blade 1 was crossing in a point and was set up connecting rod 3 at this point and connect clamp plate 4, and the height that highly equals the mould base of connecting rod 3 during the welding, on the mould base was arranged in to clamp plate 4, avoided base round trip movement.

Further, the mold base comprises a supporting plate 5 and four second supporting legs 2 arranged at the bottom of the supporting plate 5, the height of each second supporting leg 2 is larger than the thickness of the corresponding first supporting leg 1, and the gap between any two adjacent second supporting legs 2 is larger than the width of the corresponding first supporting leg 1. Preferably, the upper surface of the support plate may be provided with a shallow groove adapted to the shape of the bottom of the dry-type transformer, so that the lower end of the dry-type transformer is placed in the shallow groove for positioning.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
