[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Example 1

[0019] A workpiece processing positioning device for a CNC machine tool, such as Figures 1 to 3As shown, it includes a base plate 1, and vertical plates 2 are respectively provided at both ends of the upper surface of the base plate 1. Electric telescopic rods 4 are rotatably provided on the two vertical plates 2. The two electric telescopic rods 4 drive the clamping mechanisms to approach each other, and the distance between the two clamping mechanisms can be adjusted according to the length of the workpiece. The clamping mechanism is provided at the telescopic end of the electric telescopic rod 4, and a flip motor 3 is provided on one side of one of the vertical plates 2; the flip motor 3 drives the electric telescopic rod 4 and the workpiece on the clamping mechanism to flip together.

[0020] The clamping mechanism includes a placement plate 9 connected to the telescopic end of the electric telescopic rod 4, a plurality of placement grooves 13 provided on the placement plate 9, a pressure plate 6 provided above the placement plate 9, and a threaded column 8 which is rotatably provided on the placement plate 9 at one end. The opposite ends of the placement grooves 13 on the two placement plates 9 are respectively connected to the outside world. When placing the workpiece, its two ends are respectively abutted against one end of the placement groove 13. The cooperation of the placement plate 9 and the pressure plate 6 can realize clamping and positioning of multiple workpieces.

[0021] The bottom of the pressing plate 6 is provided with pressing grooves corresponding to the placement grooves 13, and rubber pads are provided in the placement grooves 13 and the pressing grooves to protect the workpieces. The threaded column 8 is threadedly connected to the pressing plate 6, and a knob 7 is provided on the top of the threaded column 8. There are two threaded columns 8, which are respectively provided on both sides of the pressing plate 6. Vertical plates 5 are provided on both sides of the placement plate 9. The vertical plates 5 and the placement plate 9 are an integral U-shaped structure, and slide grooves 10 are respectively provided on the opposite side surfaces of the vertical plates 5, and the two ends of the pressing plate 6 are respectively slidably provided in the slide grooves 10. The height of the pressing plate 6 can be adjusted by the threaded column 8, so that workpieces of different thicknesses can be clamped and positioned.

[0022] A guiding mechanism is provided on each placement plate 9, and the guiding mechanism includes a guiding rod 14 that is slidably penetrated through the vertical plate 2 and the placement plate 9. The guiding rod 14 is composed of two guide rods 14 that are respectively located at both ends of the vertical plate 2 and the placement plate 9, and one end of the guide rod 14 extends out of the placement plate 9 and is provided with a threaded section, on which a limiting bolt 12 is threadedly connected, and the other end of the guide rod 14 extends out of the vertical plate 2 and is connected to a limiting pull plate 11. When adjusting the distance between the two clamping mechanisms, the guide rod 14 plays a guiding role, and the limit pull plate 11 and the limit bolt 12 can prevent the two ends of the guide rod 14 from falling off the vertical plate 2 and the placement plate 9; when flipping is required, first remove the limit bolt 12, then pull the limit pull rod 11 to remove the guide rod from the placement plate 9, and then start the flipping motor 3 to drive the clamping mechanism and the workpiece to flip 180° together through the electric telescopic rod 4, so that the bottom surface of the workpiece faces upward, and then insert the guide rod 14 into the vertical plate 2 and the placement plate 9, and tighten the limit bolt 12 on the threaded section of the guide rod. At this time, the guide rod 14 can play an auxiliary supporting role for the placement plate 9.

[0023] When the utility model is used, first, the two clamping mechanisms are driven to move under the guidance of the guide rod by the extension of the electric telescopic rod 4, so as to adjust the distance between the two clamping mechanisms according to the length of the workpiece, and then the threaded column 8 is rotated by the knob 7 to make the two ends of the pressing plate 6 move up and down along the slide groove 10 to adjust the height of the pressing plate 6 so that it can meet the clamping positioning of workpieces of different thicknesses. After adjusting the height of the pressing plate 6, the two ends of multiple workpieces are respectively placed in the placement grooves 13 of the two placement plates 9, and then the pressing plate 6 is adjusted again by the threaded column 8 so that it presses the workpiece tightly in the placement groove 13, and the pressing plate is used to clamp the workpiece. After positioning, start processing the workpiece. When one side is processed, remove the limit bolt 12, then pull the limit pull rod 11 to remove the guide rod 14 from the vertical plate 2 and the placement plate 9, and then start the flip motor 3 to drive the clamping mechanism and the workpiece to flip 180° through the electric telescopic rod 4 so that the bottom surface of the workpiece faces up, then insert the guide rod 14 into the vertical plate 2 and the placement plate 9, and tighten the limit bolt 12 on the threaded section of the guide rod. At this time, the guide rod 14 can play an auxiliary supporting role for the placement plate 9, and then process the bottom surface of the workpiece. After the processing is completed, the workpiece can be taken out.
