Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

As shown in Figures 1-3, the positioning assembly in the utility model includes a support plate 1 and a positioning plate 2. When positioning the workpiece, the workpiece is placed above the support plate 1. Positioning plates 2 are arranged on both sides of the support plate 1. The support plate 1 passes through the slide groove 3 on the positioning plate 2 and the support plate 1 slides with the slide groove 3. The positioning plate 2 slides on the support plate 1, and the positioning plate 2 can move along the long axis direction of the support plate 1. A positive thread sleeve 4 and a negative thread sleeve 5 are respectively arranged on the positioning plates 2 on both sides. The driving screw rod 6 is respectively threadedly matched with the positive thread sleeve 4 and the negative thread sleeve 5. The driving screw rod 6 is provided with two sections of threads in opposite directions, which are respectively threadedly matched with the positive thread sleeve 4 and the negative thread sleeve 5. By rotating the driving screw rod 6, the positioning plates 2 on both sides can be driven to move toward the middle workpiece at the same time to clamp and position the workpiece.

The positioning plate 2 and the support plate 1 are provided with guide shafts 7 respectively. When the workpiece is placed on the support plate 1, the guide shaft 7 on the support plate 1 guides the placement of the workpiece, and when the positioning plate 2 moves toward the workpiece, the guide shaft 7 guides the positioning plate 2.

The end of the driving screw rod 6 is fixedly connected to the output end of the clamping driving motor 8, and the output shaft of the clamping driving motor 8 drives the driving screw rod 6 to rotate. In the utility model, the rotation of the driving screw rod 6 can be powered by the clamping driving motor 8.

In the flip assembly, two rotating plates 9 are respectively arranged on the outside of the positioning plate 2. The rotating plates 9 on both sides are fixedly connected by a connecting plate 10. The rotating plates 9 on both sides can rotate synchronously. Support wheels 11 are arranged on both sides of the bottom of the rotating plate 9. The support wheels 11 are rotatably installed with the supports 12. The edges of the support wheels 11 cooperate with the edges of the rotating plates 9. The support wheels 11 support the rotating plates 9 and the rotating plates 9 can rotate on the top of the support wheels 11.

Two sets of driving gears 13 are respectively fixed at both ends of the driving shaft 14, and the ends of the driving shaft 14 are fixedly connected to the output ends of the flip driving motor 18. Starting the flip driving motor 18 can drive the driving shaft 14 to rotate, and the driving shaft 14 drives the two driving gears 13 to rotate at the same time. An annular groove 15 is provided on the outer edge of the rotating plate 9, and the synchronous belt 16 is sleeved on the driving gear 13 and the annular groove 15 outside the rotating plate 9. The driving gear 13 is transmitted to the rotating plate 9 through the synchronous belt 16. Driven by the driving gear 13, the rotating plates 9 on both sides drive the positioning assembly and the workpiece in the middle to flip.

In the utility model, the edge of the support wheel 11 is provided with an annular groove 17 which matches with the protruding annular edge of the rotating plate 9. The rotating plate 9 can be supported between the two groups of support wheels 11 and can rotate due to the restriction of the annular groove 17.

The utility model is provided with a positioning component and a turning component. The workpiece is fixed on the turning component through the positioning component, and the workpiece can be turned through the turning component. The workpiece is turned to cooperate with different processes to process different surfaces.
