Description

A kind of coil winding machine

Affiliated technical field

The present invention relates to coil winding machine, especially for the coil winding machine of making the wrist-watch coil.

Background technology

Wrist-watch coil winder of the prior art, because support assembly and head disjunctor, frame coupling bar are that solid metal, all parts all are metalworks and do not adopt the shock-absorbing measure, cause that noise is big, vibrations are big, short, parts processing charges expenses of labour material of main frame and frame life-span, mass of coil is poor, and operation inconvenience and operating efficiency are low.

Summary of the invention

Purpose of the present invention is intended to overcome the deficiencies in the prior art and provides a kind of noise, vibrations little, and the part parts are used working of plastics instead, prolong main frame and frame life-span, and the workman is easy to operate, and mass of coil is superior, the coil winding machine that operating efficiency improves.

The object of the present invention is achieved like this:

A kind of coil winding machine, comprise workbench 57, line tube 15, connecting rod 7, comprise that also support assembly 130 is through plastic tube 90, fixed screw 200 with draw a screw 210, and head 140 separately is fixed on the work estrade 57 through rubber blanket 80 separately, five coupling bars 150,160,170,180,190 of frame are special-shaped hollow alloy bar, the synchronizing wheel number of teeth of driving wheel A2 in the drive system increases, and third wheel B3 is reduced to one, and the number of teeth of workpiece wheel C2 reduces.

---described frame coupling bar can be special-shaped hollow aluminium alloy bar or special-shaped hollow stainless steel strip.

---the synchronizing wheel number of teeth of described driving wheel A2 increases to 72 for good.

---the number of teeth of described workpiece wheel C2 is reduced to 24 for good.

---the platform pin of described work stage 57 adopts shock-absorbing pin 70.

It is the gearratio that changes in the drive system that the present invention reduces one of method of noise, minimizing vibrations, and its principle is as follows:

Old coil winding machine drive system is seen Fig. 1:

The synchronizing wheel tooth number Z a=52 of driving wheel A1, rotating speed is na, the tooth number Z b1=29 of third wheel B1, the tooth number Z b2=36 of B2, rotating speed are nb, the tooth number Z c=36 of active wheel C1, rotating speed are nc,

The gearratio of A1 and B1 is $\mathrm{Iab}=\frac{\mathrm{Za}}{\mathrm{Zb}1}=\frac{52}{29}=1.79$

The gearratio of B1 and C1 is $\mathrm{Ibc}=\frac{\mathrm{Zb}2}{\mathrm{Zc}}=\frac{36}{36}=1$

The gearratio of A1 and C1 is Iac=Iab * Ibc=1.79 * 1=1.79

Set na=10000 rev/min of engine speed, cincture rotation speed n b=na * Iab=10000 * 1.79=17900 so, active wheel rotation speed n c=na * Iac=10000 * 1.79=17900,

New coil winding machine drive system is seen Fig. 2:

The synchronizing wheel tooth number Z a=72 of driving wheel A2, rotating speed is na, and the tooth number Z b=36 of third wheel B3, rotating speed are nb, and the tooth number Z c=24 of active wheel C2, rotating speed are nc,

The gearratio of A2 and B3 is $\mathrm{Iab}=\frac{\mathrm{Za}}{\mathrm{Zb}}=\frac{72}{36}=2$

The gearratio of B3 and C2 is $\mathrm{Ibc}=\frac{\mathrm{Zb}}{\mathrm{Zc}}=\frac{36}{24}=1.5$

The gearratio of A2 and C2 is Iac=Iab * Ibc=2 * 1.5=3

Guaranteeing under the constant situation of active wheel rotating speed (nc=17900 rev/min)

The synchronizing wheel tooth number Z a=52 of driving wheel A1, rotating speed is na, the tooth number Z b1=29 of third wheel B1, the tooth number Z b2=36 of B2, rotating speed are nb, the tooth number Z c=36 of active wheel C1, rotating speed are nc,

Cross wheel speed $\mathrm{nb}=\frac{\mathrm{nc}}{\mathrm{Ibc}}=\frac{17900}{1.5}=11930$

Engine speed $\mathrm{na}=\frac{\mathrm{nc}}{\mathrm{Iac}}=\frac{17900}{3}=5960$

As seen after changing gearratio, guaranteeing that wheel speed can reduce by 33.5% excessively under the constant situation of active wheel rotating speed, engine speed can reduce by 40.4%, and is well-known, and noise has fallen in speed, the vibrations nature has just reduced.

The present invention reduces noise, reduce vibrations method two be to change installation method, its principle is as follows:

(a) support assembly and head separately separately are fixed on the workbench separately, and power adopts flexible the transmission.(frame and the head of old coil winding machine are fixed together, and the vibrations stack that vibrations that head produces and frame produce produces shake altogether, so vibrations are bigger).

(b) head and workbench adopt flexible the connection to increase rubber blanket 80.

(c) increase plastic tube 90 between support assembly and the workbench.

(d) frame fixed screw 200 can not be twisted too tightly.Draw a screw 210 to hold frame in order to guarantee that support assembly is not shifted to adopt.

(e) five connecting rods of frame 150,160,170,180,190 adopt special-shaped (hollow) aluminum alloy bar, also can eliminate vibrations, noise.

(f) workbench adopts shock-absorbing pin 70, causes ground in order to avoid vibrations pass, and well-known, there are a lot of platform coil winding machines in a workshop, causes ground if the vibrations of every coil winding machine all pass, and whole workshop will produce shake altogether for medium transmission vibrations with ground.

1. the present invention can prolong main frame and frame useful life: changed transmissionization, guaranteed that cincture and engine speed reduce greatly under the constant situation of active wheel rotating speed, the life-span will prolong naturally, and vibrations have reduced the life-span and also can prolong; 2. increase work efficiency: old coil winding machine is 3 bobbin winding heads, and new coil winding machine is 5 bobbin winding heads, can increase work efficiency nearly 40%; 3. make things convenient for operation: the height of bobbin winding head and work top (H) is reduced to 100mm by 200mm and can makes things convenient for the workman to operate (see figure 3); 4. easy to process: part is used working of plastics instead, makes mould, the convenient production in enormous quantities in enormous quantities; 5. mass of coil is guaranteed.
