The working principle and use process of this utility model:

When in use, the vertical rod 1 and the track rod 2 are clamped on the frame of the CNC lathe close to the cutter disc by the upper clamping plate 6 and the lower clamping plate 8, and fixed by tightening the bolts 9. By starting the electric telescopic rod 10, the output end of the electric telescopic rod 10 drives the sliding rod 12 to slide through the connecting block 11, and the sliding rod 12 drives the track rod 2 to move up and down, so as to adjust the track rod 2 to a suitable height according to the height of the workpiece. The receiving plate 14 is set on the side of the workpiece away from the cutter disc. First, the horizontal centerline position of the workpiece is determined by the tool, and then the long screw 34 is turned, and the long screw 34 drives the laser line releaser through the slider 33. The laser line 35 is moved to make the laser horizontal line emitted by the laser line maker 35 coincide with the center line position of the workpiece, and then the fixed rod 31 of the line maker 3 is adjusted according to the set size of the workpiece after turning, so that the two laser line makers 35 move up and down respectively, and the laser horizontal line emitted by the laser line maker 35 is at the peripheral position of the workpiece after turning. Finally, the lathe is started, the workpiece is rotated, and the turning tool is started. The turning tool turns the periphery of the workpiece. With continuous turning, the periphery of the workpiece gradually approaches the laser horizontal line emitted by the laser line maker 35 until the laser horizontal line coincides with the periphery of the workpiece and the laser horizontal line cuts through the periphery of the workpiece. When the peripheral surface shows a laser horizontal line on the white backing plate 15, it means that the turning has reached the set size. There is no need to repeatedly stop the lathe for measurement. The precise workpiece data can be processed in sequence. During processing, the laser line can be released through the laser line emitter 35 to determine the processing boundary of the workpiece as a positioning and reference. It is more intuitive when processing the workpiece and increases the convenience of workpiece turning. In addition, when in use, the fixed rod 31 is provided with a scale line 36 on one side of the sliding groove 32. The scale line 36 is a thousandth scale. The slider 33 is provided with an indicator block 37 on the side close to the scale line 36. When adjusting the position of the laser line emitter 35 It is convenient to confirm the adjustment data more intuitively and conveniently without the need for additional tools for measurement. In addition, debris is easily generated during turning, and a transparent glass plate is set to block the debris to prevent the debris from adhering to and damaging the white backing plate 15, and the transparent glass plate is easier to clean. In addition, when turning the workpiece, some workpieces are not the same size throughout, and different outer diameters need to be turned for different segments. A laser line emitter 25 is set, and by sliding the position of the laser line emitter 25, the laser vertical line emitted by the laser line emitter 25 is irradiated onto the workpiece, which is convenient for intuitively locating the boundary of the workpiece turning segment.
