Abstract
The utility model discloses a kind of epoxy cast dry transformer nail pressing structure, this nail pressing structure comprises hold-down bolt, locking nut and pressing plate, be pressed on pressing plate in the through hole that hold-down bolt is arranged on upper clamping piece bottom, pressing plate is arranged in the long slot bore of cushion block, and locking nut to be sleeved on hold-down bolt and to be positioned at the through hole both sides of upper clamping piece bottom.This compressing structure assembly manipulation is simple and easy; And fully ensure that the reliability of assembling, meet Production requirement.
Description
Technical field
The utility model belongs to transformer manufacture technology, relates to a kind of epoxy cast dry transformer nail pressing structure.
Background technology
The nail pressing structure of conventional epoxies dry-type transformer as shown in Figure 1.Circular hole is opened in upper clamping piece 11 bottom, is welded in hole by nail pressing nut 12.After coil 13 has been set with, cushion block 14 in placement, places pressure bowl 15 in the circular recess of upper cushion block upper surface, then nail pressing 16 is screwed in nail pressing nut, by pressure bowl, coil is exerted a force, play pressuring action, finally locate total with locking nut 17 and complete assembling.The advantage of this structure is that structure is reliable, and shortcoming is that machined piece is many, requires high to the perpendicularity of nail pressing nut and folder, and welding quality is difficult to ensure, and work efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of epoxy cast dry transformer nail pressing structure, and this compressing structure is simple for structure, and fully ensure that the reliability of assembling, meets Production requirement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of epoxy cast dry transformer nail pressing structure, it is characterized in that: this nail pressing structure comprises hold-down bolt, locking nut and pressing plate, be pressed on pressing plate in the through hole that hold-down bolt is arranged on upper clamping piece bottom, pressing plate is arranged in the long slot bore of cushion block, and locking nut to be sleeved on hold-down bolt and to be positioned at the through hole both sides of upper clamping piece bottom.
In the utility model, aperture is slightly larger than hold-down bolt, does not need to weld nail pressing nut again; Nail pressing is replaced by hold-down bolt; Hold-down bolt, locking nut is standard component; The pressing plate of design one piece of plane steel plate replaces pressure bowl; This structure also slightly adjusts upper cushion block structure, changes rectangle long slot bore into by circular slotted eye.
In the utility model, the through hole internal diameter of upper clamping piece bottom and hold-down bolt suitable, aperture is slightly larger than hold-down bolt.Pressing plate is arranged in the rectangle long slot bore of cushion block.Pressing plate is plane steel plate.
The utility model opens hole in upper clamping piece bottom, and aperture is slightly larger than hold-down bolt, does not need to weld nail pressing nut again; Nail pressing is replaced by hold-down bolt; Hold-down bolt, locking nut is standard component; The pressing plate of one piece of plane steel plate replaces pressure bowl; This structure also slightly adjusts upper cushion block structure, changes rectangle long slot bore into by circular slotted eye.
The advantage of this structure is: the reliability that ensure that assembling; Eliminate nail pressing nut, do not need weld job again, saved a large amount of man-hours, reduced the difficulty of operation; Have employed standard component in a large number, decrease machined piece to greatest extent, make whole turn to join process and all more go a step further towards standardized work; Replace machined piece with standard component, buying is convenient, and assembly manipulation is simple and easy; Replace pressure bowl structure with pressing plate, process simple and easy.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of conventional epoxies dry-type transformer nail pressing structure.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is side-looking structural representation of the present utility model.
Embodiment
A kind of epoxy cast dry transformer nail pressing structure, see Fig. 2 and Fig. 3, this nail pressing structure comprises hold-down bolt 1, locking nut 2 and pressing plate 3, be pressed on pressing plate 3 in the through hole that hold-down bolt is arranged on upper clamping piece 4 bottom, pressing plate 3 is arranged in the rectangle long slot bore of cushion block 5, and pressing plate is plane steel plate.Two locking nuts 2 to be sleeved on hold-down bolt 1 and to be positioned at the through hole both sides of upper clamping piece bottom.The through hole internal diameter of upper clamping piece bottom and hold-down bolt suitable, the aperture of upper clamping piece lower through-hole is slightly larger than hold-down bolt, does not need to weld nail pressing nut again.Nail pressing is replaced by hold-down bolt; Hold-down bolt, locking nut is standard component; The pressing plate of one piece of plane steel plate replaces pressure bowl.
After coil 6 has been set with, cushion block in placement, now in the long slot bore of upper cushion block upper surface, place pressing plate, then hold-down bolt is placed in the hole of upper clamping piece bottom, rotate the locking nut in folder notch, by pressing plate, coil is exerted a force, realize pressuring action equally, finally complete assembling with bottom locking nut location total.
This structure is in production application, safe and reliable.This structure has saved a large amount of raw materials simultaneously, decrease assembly work, reach that modernization is extensive, the needs of intensive manufacture, simultaneously because the simplification of a large amount of structure, the saving of material also meet country and propose the requirement of building economizing type, energy-saving product.
