[0013] A method for using a surfacing welding device for a tapered roller of a ring rolling machine comprises the following steps: Step 1, use the first shift wheel to move the entire surfacing device to the position of the cone roller of the ring rolling machine, then use the tool to rotate the threaded support, the threaded support descends, supports the entire surfacing device, and raises the entire surfacing device, and makes the entire surfacing device in a horizontal position, then control to open the two linear electric rails to drive the adjustment device to slide horizontally, so that the wall-attached bracket is moved to the top of the cone roller of the ring rolling machine, then control to open the first motor to drive the rotating horizontal axis to rotate, thereby driving the transmission gear to rotate, and cooperate with the meshing connection between the transmission gear and the inner side of the arc-shaped rack, the transmission gear moves on the inner side of the arc-shaped rack, thereby controlling the rotating horizontal axis and the wall-attached bracket to rotate with the rotating horizontal axis as the axis, flexibly and automatically adjusting the angle position of the wall-attached bracket, so that the angle of the wall-attached bracket is the same as the inclination angle of the upper end of the longitudinal section of the cone roller of the ring rolling machine, and use a fastening nut to screw on the outside of the fastening bolt and contact with the side end of the arc-shaped support frame to fix the position of the rotated wall-attached bracket; Subsequently, the threaded support is rotated by a tool, the threaded support moves upward, and the entire surfacing device descends until the bottom end of the wall-attached support contacts the inclined surface of the tapered roller installed on the ring rolling machine. At this time, the inclination angle of the moving slide frame is the same as the inclined surface of the tapered roller, which assists in positioning the subsequent inclination movement angle of the surfacing welding head, milling mechanism and turning mechanism. Step 2: When the bottom end of the wall-attached bracket contacts the inclined surface of the conical roller installed on the ring rolling machine, the lifting screws on the first longitudinal frame and the second longitudinal frame are rotated to control the auxiliary support seat to descend so that the auxiliary support seat contacts the ground, thereby providing auxiliary support for the surfacing device through the lifting screws and the first longitudinal frame and the second longitudinal frame; Step 3: Control and start the two linear electric rails to drive the adjustment device and the repair device to slide horizontally, so that the milling cutter head moves to the upper position of the cone roller, and control the second motor to drive the moving screw to rotate, so as to control the moving card seat to slide horizontally in the moving slide frame, and control the milling mechanism to slide along the path of the moving slide frame, so as to stably move on the inclined surface of the cone roller of the ring rolling machine until the milling mechanism moves to the damaged position of the cone roller of the ring rolling machine; Subsequently, the third motor is controlled to drive the driving gear to drive the crown gear to rotate, thereby controlling the longitudinal sliding sleeve and the longitudinal sliding rod to rotate at high speed, and then controlling the milling cutter head to rotate at high speed. At the same time, the first cylinder is controlled to drive the longitudinal sliding rod to slide up and down in the longitudinal sliding sleeve, thereby driving the milling cutter head to move up and down, and adjusting the milling depth of the milling cutter head. During this period, the milling mechanism is flexibly controlled to slide along the path of the moving slide frame, and then the high-speed rotating milling cutter head is used to mill the surrounding area of ​​the damaged position of the cone roller of the ring rolling machine, and the damaged area of ​​the damaged position of the cone roller of the ring rolling machine is appropriately increased; Step 4: After the damaged area is appropriately increased, control the opening of two linear electric rails to drive the adjustment device and the repair device to slide horizontally, so that the surfacing welding head moves to the upper position of the cone roller, and the surfacing welding head is used to perform comprehensive automatic surfacing welding on the damaged position of the cone roller of the ring rolling machine.

After the surfacing process is completed, the mobile repair device is controlled again, and the turning tool head is controlled to slide along the moving slide frame path, so that the turning tool head is moved above the surfacing position of the cone roller of the ring rolling machine. Then, the second cylinder is controlled to drive the turning tool head to rise and fall, and the cone roller installed on the ring rolling machine is driven to rotate at high speed by using an external driving device. During this period, the turning tool head is controlled to slide along the moving slide frame path again, so that the surfacing position of the cone roller of the ring rolling machine is turned by the turning tool head, so that the surface of the cone roller of the ring rolling machine is smooth, and the cone roller of the ring rolling machine can be repaired without disassembling it.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the adjustment device, the angle position of the wall-attached bracket can be flexibly and automatically adjusted, so that the bottom end of the wall-attached bracket contacts the inclined surface of the conical roller installed on the ring rolling machine, which is convenient for auxiliary adjustment of the angle of inclination of the surfacing welding head, milling mechanism and turning mechanism, and is convenient for subsequent surfacing welding repair of the damaged position of the conical roller of the ring rolling machine, without the need to disassemble the conical roller of the ring rolling machine, thereby improving the surfacing welding repair efficiency and quality of the conical roller of the ring rolling machine.

[0015] 2. By setting up the repair device, the damaged area of ​​the damaged cone roller of the ring rolling machine can be appropriately increased, which is convenient for the subsequent use of the surfacing welding head to perform surfacing treatment on the damaged cone roller of the ring rolling machine. Due to the appropriate increase in the damaged area, the surfacing material can be stably fixed at the damaged cone roller of the ring rolling machine, thereby improving the repair quality of the cone roller of the ring rolling machine.

[0016] 3. By setting up the repair device, the surfacing position of the cone roller of the ring rolling machine can be directly turned to make the surface of the cone roller of the ring rolling machine smooth without disassembling the cone roller of the ring rolling machine, which further improves the surfacing repair efficiency and quality of the cone roller of the ring rolling machine.
