Description

a winding machine

Technical field

The present invention relates to a winding machine, in particular a winding machine for making watch coils.

Background technique

The watch coil winding machine in the prior art, because the frame assembly and machine head are connected, the frame connecting rod is solid metal, all parts are metal parts and no shock absorbing measures are used, resulting in large noise and vibration. The life of the main engine and the frame is short, the processing of the machine parts is labor-intensive, the quality of the coil is poor, the operation is inconvenient and the work efficiency is low.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a winding with low noise and vibration, some components are replaced by plastic parts, the life of the main engine and the frame is prolonged, the workers are easy to operate, the coil quality is high, and the work efficiency is improved. machine.

The purpose of the present invention is achieved like this:

A winding machine, including a workbench 57, a wire barrel 15, a connecting rod 7, and a frame assembly 130 via a plastic tube 90, a fixing screw 200 and a handle screw 210, and the machine head 140 is separated by a rubber pad 80 Fixed on the workbench 57, the five connecting rods 150, 160, 170, 180, 190 of the frame are special-shaped hollow alloy bars, the number of synchronous gear teeth of the driving wheel A2 in the transmission system is increased, and the passing wheel B3 is reduced to one. The number of teeth of the wheel C2 is reduced.

——The frame connecting rod can be a special-shaped hollow aluminum alloy bar or a special-shaped hollow stainless steel bar.

——It is better to increase the number of synchronous gear teeth of the driving wheel A2 to 72.

——It is better to reduce the number of teeth of the workpiece wheel C2 to 24.

——The platform feet of the workpiece table 57 adopt shock-absorbing feet 70 .

One of the methods of reducing noise and reducing vibration of the present invention is to change the transmission ratio in the transmission system, and its principle is as follows:

The transmission system of the old winding machine is shown in Figure 1:

The synchronous wheel tooth number Za=52 of driving wheel A1, the rotating speed is na, the tooth number Zb1=29 of passing wheel B1, the tooth number Zb2=36 of B2, the rotating speed is nb, the tooth number Zc=36 of working wheel C1, the rotating speed is nc,

The transmission ratio between A1 and B1 is $\mathrm{Iab}=\frac{\mathrm{Za}}{\mathrm{Zb}1}=\frac{52}{29}=1.79$

The transmission ratio between B1 and C1 is $\mathrm{Ibc}=\frac{\mathrm{Zb}2}{\mathrm{Zc}}=\frac{36}{36}=1$

The transmission ratio of A1 and C1 is Iac=Iab×Ibc=1.79×1=1.79

Set the host speed na=10000 rev/min, then the side wheel speed nb=na×Iab=10000×1.79=17900, the working wheel speed nc=na×Iac=10000×1.79=17900,

The transmission system of the new winding machine is shown in Figure 2:

The number of teeth of the synchronous wheel of driving wheel A2 Za=72, the speed is na, the number of teeth Zb=36 of the passing wheel B3, the speed is nb, the number of teeth Zc=24 of the working wheel C2, the speed is nc,

The transmission ratio between A2 and B3 is $\mathrm{Iab}=\frac{\mathrm{Za}}{\mathrm{Zb}}=\frac{72}{36}=2$

The transmission ratio between B3 and C2 is $\mathrm{Ibc}=\frac{\mathrm{Zb}}{\mathrm{Zc}}=\frac{36}{\mathrm{twenty\; four}}=1.5$

The transmission ratio of A2 and C2 is Iac=Iab×Ibc=2×1.5=3

Under the condition that the rotation speed of the working wheel is kept constant (nc=17900 rpm)

The synchronous wheel tooth number Za=52 of driving wheel A1, the rotating speed is na, the tooth number Zb1=29 of passing wheel B1, the tooth number Zb2=36 of B2, the rotating speed is nb, the tooth number Zc=36 of working wheel C1, the rotating speed is nc,

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

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

It can be seen that after changing the transmission ratio, under the condition that the speed of the working wheel remains unchanged, the speed of the passing wheel can be reduced by 33.5%, and the speed of the main engine can be reduced by 40.4%. As we all know, the noise and vibration are naturally reduced when the speed is reduced.

The second method of the present invention to reduce noise and reduce vibration is to change the installation method, and its principle is as follows:

(a) The frame assembly and machine head are separated and fixed on the workbench separately, and the power is transmitted flexibly. (The frame and machine head of the old winding machine are fixed together, and the vibration generated by the machine head and the vibration generated by the frame are superimposed to produce resonance, so the vibration is greater).

(b) A rubber pad 80 is added to the machine head and the workbench through flexible connection.

(c) A plastic pipe 90 is added between the rack assembly and the workbench.

(d) The frame fixing screws 200 cannot be tightened too tightly. In order to ensure that the frame assembly does not shift, pull handle screws 210 are used to hold the frame.

(e) Five connecting rods 150, 160, 170, 180, 190 of the frame adopt special-shaped (hollow) aluminum alloy bars, which can also eliminate vibration and noise.

(f) The workbench adopts shock-absorbing feet 70 to prevent the vibration from being transmitted to the ground. As we all know, there are many winding machines in a workshop. If the vibration of each winding machine is transmitted to the ground, the entire workshop will use the ground as the medium to transmit Vibration produces resonance.

The present invention can ① prolong the service life of the main engine and the frame: the transmission is changed, and while the rotating speed of the working wheel is kept constant, the rotating speed of the side wheel and the main engine is greatly reduced, and the service life will naturally be extended, and the service life will also be extended if the vibration is reduced; ② Improve work efficiency: the old winding machine has 3 winding heads, and the new winding machine has 5 winding heads, which can improve the work efficiency by nearly 40%; ③ Convenient work and operation: the height (H) of the winding head and the working table is reduced from 200mm Reduced to 100mm, it is convenient for workers to operate (see Figure 3); ④ easy processing: some parts are replaced by plastic parts to make molds, which is convenient for mass production; ⑤ coil quality can be guaranteed.
