Inverter transmission system Main shaft feeding device

(Diagram I) Drilling machine main structures diagram

② Working principle

1) Major cutting motion-main shaft rotation working principle

Main shaft rotation motion is powered by motor input via multiple

levels of belt transmission and inversion, which ultimately drives the

main shaft.

2) Feeding motion working principle

Main shaft feeding motion is realized by manually driving the rack on

main shaft sleeve through force amplifier and gear shaft. Additionally,

there is a precise feeding device to control and improve the

processing precision.

3) Main shaft box lifting device working principle

As regards the lifting device installed on the main shaft box, manually

rotate the worm, which will drive the angular gear, and the

counterforce arising from the rolling of angular gear along the rack

(axially fixed on the stand column) will drive the main shaft box to go

UP or DOWN.

4) Main shaft sleeve fixed-travel feeding working principle

It can be divided into rough travel fixing and precise travel fixing as


- 8 -

per the precision of the travel fixing. During the rough travel fixing, the

finger will point to the scale line on the nameplate with the minimum

feeding unit of “1mm”; whilst the precise travel fixing is adopting the

worm and worm gear principle to drive the motion of the main shaft

sleeve with the minimum unit of “0.05mm”.

VI Transmission system

① Major transmission system;

The major transmission system of the drilling machine adopts belt

auxiliary transmission and spline auxiliary transmission. Its transmission

route is: motor→belt wheel→spline sleeve→main shaft. When 1.5Kw

1400r/min motor is used as the power source, 12-level inversion

transmission can be achieved by changing the position on triangle

rubber belt pulley. The way to change the speed is: firstly cut off the

power supply, and then open two hasps on the side of the cover; open

the cover, loosen the vane screws, and push the motor toward the main

shaft box. After regulating the triangle rubber belt, push out the motor to

tighten the triangle rubber belt, tighten the vane screws, close the cover

and lock the hasps (Speed indication plate is attached inside the cover).

Attention:

Power supply MUST be cut off during the change of speed!

② Main shaft feeding device is divided into two types:

1）Direct feeding: The feeding handle fixed on the gear shaft will

directly drive the main shaft feeding, where one circle rotation of the

handle leads to the main shaft travel of 88mm.


- 9 -

2）Precise feeding: The main shaft feeding handle will drive the main

shaft feeding driven by gear shaft via tapered clutch, where one circle

rotation of the main shaft handle leads to the main shaft travel of

2.5mm.

③ Lifting transmission system:

Its transmission route is: rocker→worm→angular gear→rack.

④ Working table feeding is realized by lead screw driven by the handle,

where one circle rotation of handle wheel leads to the working table

travel of 2.5mm.
