The working principle and the working process of the invention are as follows:
an operator clicks a start button on an operation display screen 1103, controls a workstation 11 to control a hydraulic cylinder II 4 to extend out, jacks up a milling heating device 7, opens a clamp cover 902, selects a pair of upper slips 903 and lower slips 904 suitable for the size of a pipeline, fastens the upper slips 903 on the clamp cover 902, fastens the lower slips 904 on a clamp seat 901, places two pipelines between slips of a movable clamping device and a fixed clamping device respectively, sets the positions of the pipelines, lowers the clamp cover 902, and screws a fastening nut 905;
then, a milling button is clicked on the operation display screen 1103, the workstation 11 is controlled to control the second hydraulic cylinder 4 to retract, and the clamping groove 8 on the milling heating device shell 711 is clamped on the first supporting pipe 103 and the second supporting pipe 104 to ensure the overall stability; because high-temperature-resistant heat-conducting liquid is not introduced, the cutter head 702 is in a milling state (namely an initial state) at the moment, the telescopic table 7021 is tightly attached to the bottom surface of the main body groove 7027-7 through the tensile force of the first return spring 7023, the milling cutter 7022 is in an extending state, the limiting block 7026 is extruded to the position under the milling cutter 7022 by the telescopic table 7021, meanwhile, the small boss 7026-4 supports and clamps the milling cutter 7022 to limit the movement of the milling cutter 7022, the milling cutter 7022 is prevented from retracting when the end surface of a pipeline is milled, and meanwhile, the second return spring 70210 is in a compressed state.
Then the motor 707 is electrified to rotate to drive the two-sided cutterhead 702 to rotate, after the fixed rotation speed is reached, the workstation 11 is controlled to control the hydraulic pump 1202 to rotate, high-pressure oil liquid is introduced into the hydraulic cylinder I2 through the hydraulic cylinder interface 121, the hydraulic cylinder I2 drives the movable clamping device to move towards the fixed clamping device, so that the two pipelines are tightly attached to the two end faces of the milling heating device 7, and at the moment, the sliding platform spring 13 is compressed or stretched; the milling cutter 7022 continuously mills the end face of the pipeline under the action of rotation, and a part of space reserved by the sinking of the telescopic table 7021 serves as a chip cutting groove, so that chips are smoothly discharged; when continuous and uniform cutting chips exist, an operator clicks a milling completion button on the operation display screen 1103, the first hydraulic cylinder 2 drives the movable clamping device to be far away from the fixed clamping device, and the sliding platform spring 13 resets to separate the milling heating device 7 from the pipe fitting.
The control workstation 11 controls the second hydraulic cylinder 4 to extend out to jack up the milling heating device 7, the motor 707 is powered off to stop rotating, an operator clicks a heating end face button on the operation display screen 1103 after checking that the milling of the two end faces is qualified, the control workstation 11 controls the second hydraulic cylinder 4 to retract, and the milling heating device 7 returns to the working position again; the constant-temperature pumping device 10 continuously provides power for the high-temperature-resistant heat-conducting liquid through a pump inside the constant-temperature pumping device, then starts to convey the high-temperature-resistant heat-conducting liquid, outputs the high-temperature-resistant heat-conducting liquid through a high-temperature-resistant heat-conducting liquid interface 1104, flows into a liquid guide groove 7028 from a liquid inlet in a liquid conveying port 7029 through a connecting pipeline 6, a pipeline interface 701, an internal pipeline 705, an annular groove 708, a communicating hole 706, a liquid conveying hole 714 and a pipeline butt joint 715, flows through the whole cutter head main body 7027 to enable the cutter head main body to be uniformly heated, flows out from a liquid return port in a liquid conveying port 7027-9 to reach a liquid inlet in a liquid conveying port 7021-5 through a connecting hose 70212, and further flows into a liquid conveying groove of a telescopic table 7021 to enable the telescopic table 7021 to be uniformly heated, and accordingly the surface of the whole cutter head to be uniformly heated; and the liquid flows back to the constant-temperature pumping device 10 through a liquid return port in the second infusion port 7021-5, a connecting hose 70212, a liquid inlet in the third infusion port 7027-9, a liquid guide groove 7028, a liquid return port in the first infusion port 7029, a pipeline butt joint 715, an infusion hole 714, a communication hole 706, an annular groove 708, an internal pipeline 705, a pipeline interface 701, a connecting pipeline 6 and a high-temperature-resistant heat-conducting liquid interface 1104 to form circulation.
