[0069] The driving motor 19 is controlled by a pre-set program to control the intermittent rotation of the driving motor 19 and the rotation angle each time; the driving motor 19 drives the gear 20 to rotate, the gear 20 engages the transmission gear ring 21, and the gear ring 21 drives the rotating body 4 to rotate, and the barrel-shaped component is fixed on the rotating body 4 by the clamping block 6, so the driving motor 19 can drive the barrel-shaped component to rotate accurately at a certain angle, ensuring the precision processing of the barrel-shaped component;

[0070] Before the processing equipment is used, the driving motor 19 will drive the swivel 4 to reset, so that each oil filling hole 14 corresponds to the insert tube 25 one by one, and then the barrel-shaped component is placed in the swivel 4, and then the cylinder 24 is driven to insert the insert tube 25 into the oil filling hole 14 and press against the end face of the plugging head 16, and the plugging head 16 moves toward the piston rod 13, no longer blocking the oil filling hole 14, and the oil outlet 26 of the insert tube 25 is completely placed in the oil filling hole 14, and then the external oil pump is driven to inject hydraulic oil into the insert tube 25, and the oil flows into the piston cylinder 12 from the oil outlet 26 to push the piston rod 13 out; after the external push is completed, the external oil pump stops supplying oil, the cylinder 24 drives the slider 22 away from the clamping block 6, and the insert tube 25 is pulled out of the oil filling hole 14, at this time, the plugging head 16 is reset under the elastic force of the compression spring 15 to block the oil filling hole 14;

[0071] When the barrel-shaped component is processed, the driving assembly drives the wheel body to rotate and reset, so that each oil filling hole 14 corresponds to the insert tube 25 one by one, and then drives the cylinder 24 to insert the insert tube 25 into the oil filling hole 14 and press against the end surface of the plugging head 16. The plugging head 16 moves toward the piston rod 13. At the same time, the oil pipe connected to the insert tube 25 and the oil pump are in the state of pumping oil. Under the elastic force of the reset spring 11 connected to it, the clamping block 6 retreats and resets, and squeezes the piston rod 13 toward the piston cylinder 12, presses the hydraulic oil in the piston cylinder 12 into the insert tube 25, and flows back to the external oil barrel;

[0072] The processing motor 28 delivers a fixed milling cutter, and the processing cutter is perpendicular to the inner surface of the barrel-shaped component, and cooperates with the hydraulic cylinder 7 to adjust the feed amount of the milling cutter, so as to flexibly process the inner cavity surface of the barrel-shaped component;

[0073] The rotary motor 9 drives the processing motor 28 to rotate through the cross bar 27, so that the processing motor 28 performs rotary processing. At the same time, the processing motor 28 drives the milling cutter to rotate, that is, the milling cutter rotates and revolves around the axis of the cross bar 27, and can perform rotary processing on the inner cavity of the barrel-shaped component, or process the eccentric position of the inner cavity of the barrel-shaped component; when the axis of the cross bar 27 coincides with the axis of the inner cavity of the barrel-shaped component, the inner cavity of the barrel-shaped component can be processed; when the axis of the cross bar 27 does not coincide with the axis of the inner cavity of the barrel-shaped component, the eccentric position of the inner cavity of the barrel-shaped component can be processed;

[0074] The processing motor 28 itself performs a rotary motion, and the power supply of the processing motor 28 needs to be considered; for this purpose, a conductive component is set up; an external wire connects the conductive rod 30, and the fixed ring 29 is fixedly connected to the end shell of the rotary motor 9. The conductive rod 30 is inserted into the annular groove 31. A ring-shaped conductive plate is provided in the annular groove 31. The conductive plate is in electrical contact with the conductive rod 30, and the conductive plate is electrically connected to the processing motor 28 through a wire; the rotary motor 9 drives the cross bar 27 to rotate, and the movable ring 23 rotates, and at the same time, the conductive rod 30 performs a relative rotational motion in the conductive plate; a rotating roller body 32 is provided at the end of the conductive rod 30, and the sliding friction between the conductive rod 30 and the conductive plate is converted into a rolling friction between the roller body 32 and the conductive plate, thereby reducing the wear of the conductive rod 30 itself and improving the relative rotation smoothness of the movable ring 23 and the fixed ring 29.
