Embodiment Construction
[0012] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0013] like figure 1 As shown, the three-axis steel pipe intersecting line cutting machine of the present invention includes a spindle box located at one end of the cutting machine. A number of steel pipe support frames are provided for supporting the steel pipes; on the upper part of the base, at the height of the rotary chuck, parallel to the base track, a crossbeam 4 with a length similar to the fuselage is provided, supported on the base by a bracket 5, the cutting head The moving assembly 3 can slide horizontally on the guide rail of the crossbeam 4, and realize power and electrical connection with the power part and the control part through the pipeline protected inside the roller chain. The cutting head moving assembly 3 includes a cutting head longitudinal moving part 100, a cutting head lifting mechanism 200. The cutting head swi...

The invention relates to a cutting head elevating mechanism of a triaxial steel pipe intersecting line cutting machine. The cutting head elevating mechanism is arranged on a cutting head longitudinal moving part through a right angle side plate; a linear guide rail is vertically arranged on the other right angle surface of the right angle side plate, an electric motor is fixed on the right angle side plate, the output shaft of the electric motor is connected with a lead screw; an elevating block is provided with a nut meshed with the lead screw and also provided with a slider which fits with the linear guide rail; and the limit block of the elevating block fits with a limit switch on the right angle side plate. The cutting head elevating mechanism of the invention has simple, compact and reasonable structure; the servo motor fits with the lead screw and the nut, the elevating mechanism is accurate to position and simple to assemble, the precise linear guide rail is adopted to fit, the movement is smooth and reliable; the linear guide rail pair can expand the travel range of the cutting torch, the maximum travel range can reach 320mm; the control accuracy and cutting efficiency are high, and the load capacity is large.
Description
technical field [0001] The invention relates to the field of steel pipe processing equipment, in particular to a steel pipe intersecting line cutting machine. Background technique [0002] Complicated pipelines require multiple pipelines to be connected. At present, the intersecting line cutting of steel pipes is basically done by manual lofting, followed by manual flame gun or plasma gun cutting. The biggest disadvantage of this manual cutting is that it is difficult to guarantee the cutting accuracy. The surface is rough, and the labor intensity is high, and the production efficiency is low. The existing steel pipe intersecting line cutting machine can complete the cutting of steel pipe intersecting line well, but its cutting head lifting mechanism is very heavy and inflexible in movement, the impact is large and unstable, and the control accuracy cannot meet the requirements; the load capacity is relatively low. Small and expensive. Contents of the invention [0003] ...
