[0022] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown in the schematic diagram of a flange processing machine, the fixed coil 2 is fixed to the outer wall of the pipe fitting 8 to be processed by the fastening bolt 14 and the fastening clamp 15, and the base of the θ-axis main motor 9 is fixedly connected to the fixed coil 2.

[0023] The moving coil 1 is located on the outer ring of the fixed coil 2. The fixed coil 2 and the moving coil 1 are connected by a crossed roller bearing, which enables smooth rotation of the fixed coil 2 and the moving coil 1 under longitudinal stress. The θ-axis main motor 9 is connected to the moving coil 1 through a belt drive mechanism 10, driving the moving coil 1 to continuously rotate around the fixed coil 2. A bridge 3 is installed on the moving coil 1. A linear guide is installed on the bridge 3. A radial ball screw is provided on the guide rail. An r-axis slider 4 is installed on the radial ball screw. The ball screw drives the slider 4 to complete radial linear movement.

[0024] An r-axis motor 11 is provided inside the bridge. The r-axis motor 11 is drivingly connected to the radial ball screw. A vertical guide groove is provided on the r-axis slider 4. A vertical screw is provided in the guide groove. The tool holder 6 is located in the guide groove and is connected to the vertical screw. The turning tool 7 is installed on the tool holder and is perpendicular to the machining surface. An end of the r-axis slider 4 is equipped with a Z-axis motor 12, and the Z-axis motor 12 drives the turning tool 7 to move vertically. The controller is respectively connected to the θ-axis main motor, the r-axis motor, and the Z-axis motor through wires. A support 5 is provided on the bridge 3, and a conductive slip ring is installed on the support. On the one hand, the conductive slip ring is connected to an external power supply for power supply, and on the other hand, it is respectively connected to the r-axis motor, the Z-axis motor, and the controller through wires.

[0025] Preferably, the guide groove is a dovetail groove to ensure the correct cutting angle of the tool. The vertical screw is a nut screw.

[0026] Preferably, the transmission mechanism connecting the θ-axis main motor to the moving coil can also be a gear pair.

[0027] The controller can also be connected to an external computer, and through computer control, more precise and convenient control can be achieved.

[0028] In this way, under the control of the controller, the θ-axis main motor drives the turning tool to move around the pipe fitting to be machined, the r-axis motor drives the turning tool to move radially on the pipe fitting to be machined, and the Z-axis motor drives the turning tool to move axially on the pipe fitting to be machined, thereby precisely machining the flange surface. This flange processing machine combines modern lifestyles and uses a touch screen controller for operation instead of traditional complex buttons and handles, with a zero learning curve. The user only needs to simply set the machining radius and machining depth required for the workpiece to be machined, and through automatic programming, the machining tool path is intelligently generated, and the required machining duration is calculated, and then automatic machining can be started. And the remaining machining duration is displayed in real time on the controller APP interface, enabling real-time monitoring of the machining progress.
