[0017] Embodiment 1:

[0018] The following is combined with Figure 1-2 The utility model is described in detail with specific implementation modes.

[0019] A double-axle reduction truck power head comprises a power head housing 1, a cutter head shaft 2, a driving shaft 3 and a motor 4.

[0020] The power head housing 1 comprises a housing cover 11 and a shaft end cover 12. The power head housing 1 protects the gears and bearings on the cutter head shaft 2 and the driving shaft 3 from being affected by flying chips generated during the machining process.

[0021] The cutter head shaft 2 includes a cutter head shaft gear 21, a counterweight balance wheel 22, and a cutting head 23;

[0022] The driving shaft 3 includes a driving shaft gear 31 and a driving shaft synchronous wheel 32;

[0023] The motor 4 is fixed on a motor mounting plate 41 , and includes a motor synchronous wheel 42 and a synchronous belt 43 .

[0024] The motor 4 is connected to a motor synchronous wheel 42 , and the motor synchronous wheel 42 is connected to the driving shaft 3 via a synchronous belt 43 . The driving shaft 3 is connected to the cutter disc shaft 2 via the meshing of the driving shaft gear 31 and the cutter disc shaft gear 21 .

[0025] A counterweight balance wheel 22 is disposed on one side of the cutter head shaft 2, and a car cutter head 23 is connected to the other side.

[0026] The motor 4 can be controlled by the numerical control system to adjust the rotation speed in real time, thereby adjusting the rotation speed of the cutting disc 23 in real time.

[0027] The counterweight balancing wheel 22 is used to adjust stability and balance, so that the equipment operates more stably and ensures the weight balance on both sides of the cutter head shaft 2.

[0028] In this embodiment, the number of teeth on the cutter shaft gear 21 is greater than the number of teeth on the driving shaft gear 31, which plays a role in reducing speed and increasing torque.

[0029] How it works

[0030] The motor 4 drives the connected motor synchronous wheel 42, and the motor synchronous wheel 42 drives the driving shaft synchronous wheel 32 through the synchronous belt 43, thereby driving the driving shaft 3, and the driving shaft 3 drives the cutter head shaft gear 21 through the gear, and the cutter head shaft gear 21 drives the cutter head shaft 2 to rotate, so that the turning cutter head 23 on the cutter head shaft 2 rotates; this power head is installed on the lathe pallet, and the speed ratio of the spindle and the turning power head, as well as the power head feed are controlled by the lathe system to complete the turning processing.
