The positioning assembly 3 includes a vertical column 9, a bottom plate 10 is fixedly installed on one side of the vertical column 9, and L-shaped plates 11 are fixedly installed on both sides of the bottom plate 10. A plurality of balls 12 are movably embedded at the lower end of the L-shaped plate 11. Inclined rods 15 are fixedly installed at the front and rear ends of the vertical column 9, and an inclined plate 16 is movably installed between the two inclined rods 15. A rubber pressure roller 17 is fixedly installed at the lower end of the inclined plate 16 near one side, and an electric push rod 13 is fixedly installed at the upper end of the bottom plate 10. First, the parts to be processed are placed on a Between the positioning components 3, according to the length of the component, the electric telescopic rod 18 is started, so that the electric telescopic rod 18 drives the base plate 10 and the vertical column 9 to move to the appropriate position, and then the electric push rod 13 is started to rotate the inclined plate 16 so that the rubber pressure roller 17 is just pressed on the top of the component. When processing one side of the component, the rubber pressure roller 17 on one side will no longer press the component, so that it is convenient for the cutting tool to process one side of the component, but the component on the other side is always pressed against the component, so that the component will not shift during processing. Conversely, when processing the other side of the component, the rubber pressure roller 17 on the other side will no longer press the component.

[0022] In this embodiment, two limit blocks 14 are fixedly mounted on the lower end of the inclined plate 16 , and the top of the electric push rod 13 is located between the two limit blocks 14 and is movably connected via a movable rod.

When processing one side of the parts, the rubber pressure roller 17 on one side no longer presses the parts, so that the cutting knife is convenient for one side of the parts. During processing, the parts on the other side are always pressed against the parts, so that the parts will not shift during processing. Conversely, when the other side of the parts is processed, the rubber pressure roller 17 on the other side no longer presses the parts. During processing, dust is generated on the surface of the workbench 1. At this time, the L-shaped column 4 is moved, and the negative pressure fan 6 is started to make the soft suction cup 8 generate suction. After the soft suction cup 8 is located in a suitable position, the gooseneck tube 7 can be deformed, so that the soft suction cup 8 can be held by hand to absorb the debris on the surface of the workbench 1 and suck it into the storage box 5 for centralized collection.
