[0016] There are two first stoppers.

[0017] There are two second stoppers.

[0018] The above structure of the present application can achieve the following beneficial effects:

[0019] During processing, the workpiece is placed at the processing station on the bridge plate, one end of the clamping plate is placed on the workpiece, and then the first bolt is tightened to clamp the workpiece between the clamping plate and the bridge plate, and several clamping plates are used to fix the workpiece from both sides of the workpiece to ensure that the workpiece will not move during the processing.

[0025] The following is combined with Figure 1-2 The utility model is described in further detail.

[0026] Reference Figure 1-2 A rotary support machining tooling comprises: a base 1, a bridge plate 2, a fixing mechanism and a driving mechanism are arranged on the base 1, the bridge plate 2 is horizontally arranged on the base 1, both ends of the bridge plate 2 are rotatably connected to the base 1, and the driving mechanism is used to drive the bridge plate 2 to rotate; the fixing mechanism comprises a plurality of splints 3, a processing station is provided on the bridge plate 2, and a plurality of splints 3 are respectively arranged on both sides of the processing station, and a first bolt 4 is provided on the splint 3, the first bolt 4 passes through the splint 3 from the top surface of the splint 3, and the bottom end of the first bolt 4 is threadedly connected to the bridge plate 2. In this way, during processing, the workpiece is placed at the processing station on the bridge plate 2, one end of the splint 3 is placed on the workpiece, and then rotated. The first bolt 4 is tightened to clamp the workpiece between the clamping plate 3 and the bridge plate 2, and several clamping plates 3 are used to fix the workpiece from both sides of the workpiece (in this embodiment, four clamping plates 3 are provided, and two clamping plates 3 are provided on both sides of the processing station respectively) to ensure that the workpiece does not move during the processing. Since a driving mechanism is provided to drive the bridge plate 2 to rotate on the base 1, when one side of the workpiece is processed, the bridge plate 2 is rotated to make the other side of the workpiece face the side of the processing equipment, and the processing can be continued without re-fixing the workpiece, which is very convenient. Moreover, since the position of the workpiece relative to the bridge plate 2 has not changed, it is convenient to position it for re-processing, which is beneficial to improve the accuracy of workpiece processing.

[0027] Reference Figure 2 In order to improve the flexibility of the splint 3, a waist-shaped groove is provided on the splint 3, and the first bolt 4 is passed through the waist-shaped groove. In this way, the first bolt can move in the waist-shaped groove to change the position of the splint 3, so that the splint 3 can clamp different workpieces.

Since a driving mechanism is set to drive the bridge plate 2 to rotate on the base 1, when one side of the workpiece is processed, the bridge plate 2 is rotated so that the other side of the workpiece faces the side of the processing equipment, and processing can continue without re-fixing the workpiece, which is very convenient. Moreover, since the position of the workpiece relative to the bridge plate 2 has not changed, it is convenient to position the workpiece for re-processing, which is beneficial to improving the accuracy of workpiece processing.
