Example Embodiment

[0028] Example: Combining Figure 1 ~ Figure 5 As shown, the semi-automatic laser pipe cutting machine provided by the present invention has a frame 1, and the frame 1 is provided with a laser automatic cutting device and a pipe fixing device, wherein: the laser automatic cutting device has an X axis The gantry 3 of the traveling drive device 2 and the laser cutting device 5 arranged on the gantry 3 by the Y-axis traverse drive device 4, the X-axis and Y-axis constitute a horizontal rectangular coordinate system; the pipe fixing device is located at The tightening device and the rotary pneumatic chuck 6 arranged opposite to the X-axis travel direction of the gantry 3 under the laser cutting device 5, and the pipe supporting device arranged between the tightening device and the rotary pneumatic chuck 6 are formed together.
[0029] The rotary pneumatic chuck 6 described in this embodiment is a prior art, and it is composed of a four-jaw pneumatic chuck 6a and a rotary cylinder 6b connected to and driving the four-jaw pneumatic chuck 6a to rotate. The structure of the tightening device is as follows: it has a movable seat 7 assembled on the frame 1 by an X-axis screw drive pair and a cone pivotally mounted on the movable seat 7 and opposite to the rotary pneumatic chuck 6 形头8。 Shaped head 8. The structure of the X-axis screw drive pair is the same as the conventional technology. It has a screw 14 arranged on the frame 1 and a nut arranged on the movable seat 7 and matched with the screw 14, and one end of the screw 14 is arranged There is a crank handle 15, which is convenient for workers to operate, as in figure 2 , image 3 with Figure 4 Shown. At the same time, the frame 1 is provided with a movable seat linear guide 9 that guides the movable seat 7 to travel along the X axis. In this embodiment, the movable seat linear guide 9 adopts a conventional ball linear guide, which is provided on the frame 1 and Two rail bodies 9a arranged in parallel and a sliding element slidably arranged on the rail body 9a, the sliding element is fixed at the bottom of the movable seat 7, see for details Figure 2 to Figure 5 Shown.
[0030] In this embodiment, the X-axis traveling driving device 2 is a towline device fixed on the frame 1 and connected with the gantry 3. At the same time, the frame 1 is provided with a gantry linear guide 10 that guides the gantry 3 to travel along the X axis. The gantry linear guide 10 adopts a conventional ball linear guide and has two parallel-arranged two A guide rail body and a sliding element slidably arranged on the guide rail body, the sliding element is fixed at the bottom of the gantry 3, see figure 2 with Figure 5 Shown.
[0031] In this embodiment, the laser cutting device 5 is composed of a laser (not shown) and a laser cutting head 5a connected to the laser, and the laser cutting head 5a faces vertically downward, see details figure 1 , image 3 with Figure 5 Shown.
