Background technology
In the production technology of transformer, need iron core is carried out coil winding.Prior art uses coiling
Machine completes this technique: by iron core sleeve in rotating shaft, then drives rotating shaft and iron core circumference by rotating shaft electric motor
Rotate, then the winding trend of staff's control coil.But in coil-winding process, due to each
The impact of factor, the actual coil diameter easily causing the outer coiling of iron core is bigger than score loop diameter, not only makes
The production cost becoming transformer improves, and process open circuit loss is excessive, temperature is too high in use also to make transformer
And be easily caused coil and be burned, have a strong impact on production safety.
Utility model content
The purpose of this utility model is to provide a kind of transformer coil diameter control device, the utility model structure
Simply, reasonable in design, it is possible to press to reduce coil diameter to transformer wire loop diameter.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
A kind of transformer coil diameter control device, including by frame, be positioned between frame and be arranged with iron core
The coil winding machine that rotating shaft and the coiling electric motor driving rotating shaft to circumferentially rotate form, described frame is provided with frame plate,
Being provided with screw mandrel between frame plate, screw mandrel one end is connected with rotary electric machine, is provided with fixing seat directly over iron core, fixing
The internal thread hole of seat is connected with wire rod thread, and fixing seat bottom portion is connected with the cylinder barrel of hydraulic cylinder, the work of hydraulic cylinder
Stopper rod is connected with for pressing the briquetting of coil on iron core.
Preferably, described device also includes being arranged between frame plate and being positioned at the guide post above screw mandrel, guides
The pilot hole that bar is arranged with fixing seat top coordinates.
Preferably, described device includes control system, control system by holding wire respectively with hydraulic cylinder and turn
Dynamic motor connects.
Preferably, described iron core be arranged right below range sensor, range sensor pass through holding wire and control
System processed connects.
When coil winding, the coil of each position of the real-time inductive iron core of range sensor immediately below iron core
And the spacing between it, when somewhere coil and when being smaller than setting value of range sensor, i.e. table on iron core
Open-wire line loop diameter exceeds aimed dia, and range sensor transmits signal to control system, and control system controls to turn
Dynamic driven by motor screw mandrel rotates a fixing turn so that fixing seat drives hydraulic cylinder to move to corresponding coil,
Then the piston rod of control system control hydraulic cylinder stretches out, by briquetting coil pressing to improve the density of coil
And reduce the diameter of coil.After the sensing spacing that coil diameter at this meets range sensor, Distance-sensing
Device transmits signal to control system, and control system controls the piston rod retraction of hydraulic cylinder, and controls rotary electric machine
Drive screw mandrel rotates backward so that fixing seat resets.
The start and stop of motor, hydraulic cylinder piston rod stretch out and bounce back and range sensor by control system (as
Can be PLC control system) carry out automation manipulation, its concrete control method belongs to art technology
The common knowledge of personnel, therefore repeat no more, wherein range sensor can be multiple.
Certainly, range sensor and arranging of control system are a kind of technical scheme more optimized, this reality
With novel when not using range sensor, manual measurement coil diameter can be passed through, the most again by controlling
Rotary electric machine and hydraulic cylinder operation also can realize reducing transformer wire loop diameter.
The utility model compared with prior art, has the advantage that simple in construction, reasonable in design, passes through
Coil diameter is monitored by range sensor in real time, and uses hydraulic cylinder to coordinate briquetting that coil is compressed pressure
Real, to reduce coil diameter.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, the utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain the utility model, is not used to limit the utility model.
As it is shown in figure 1, a kind of transformer coil diameter control device, including by frame 1, be positioned at frame 1
Between and be arranged with iron core 3 rotating shaft 2 and drive rotating shaft 2 circumferentially rotate coiling electric motor 4 composition coiling
Machine, described frame 1 is provided with frame plate 5, is provided with screw mandrel 6 and guide post 11, guide post 11 between frame plate 5
Being positioned at above screw mandrel 6, screw mandrel 6 one end is connected with rotary electric machine 7, and iron core 3 is arranged right below Distance-sensing
Device 13, is provided with fixing seat 8 directly over iron core 3, the internal thread hole of fixing seat 8 is threadeded with screw mandrel 6,
The pilot hole that fixing seat 8 top is arranged coordinates with guide post 11, fixes the cylinder with hydraulic cylinder 9 bottom seat 8
Cylinder connects, and the piston rod of hydraulic cylinder 9 is connected with the briquetting 10 being used for pressing coil on iron core, control system
12 are connected with hydraulic cylinder 9, rotary electric machine 7 and range sensor 13 respectively by holding wire.
Real-time each position of inductive iron core of range sensor 13 when coil winding, immediately below iron core 3
Coil and spacing between it, when on iron core somewhere coil and range sensor 13 be smaller than set
During value, i.e. showing that coil diameter exceeds aimed dia, range sensor 13 transmits signal to control system 12,
Control system 12 controls rotary electric machine 7 and drives screw mandrel 6 to rotate a fixing turn so that fixing seat 8 band hydrodynamic
Cylinder pressure 9 moves to corresponding coil, and then control system 12 controls the piston rod of hydraulic cylinder 9 and stretches out,
By briquetting 10 coil pressing to improve the density of coil and to reduce the diameter of coil.Treat coil diameter at this
After meeting the sensing spacing of range sensor 13, range sensor 13 transmits signal to control system 12,
Control system 12 controls the piston rod retraction of hydraulic cylinder 9, and controls rotary electric machine 7 and drive screw mandrel 6 reverse
Rotate so that fixing seat 8 resets.
