[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 3 The utility model provides a technical solution: a multi-station rotary fixture, including a base 1 and a support table, two brackets 2 are installed on the base 1, and support shafts 15 are provided at both ends of the support table. The two support shafts 15 are rotatably installed on the brackets 2. The support table includes a support frame 3, and a mounting plate 4 is provided on the top of the support frame 3. The two ends of the support frame 3 are connected to the support shafts 15 through connecting seats 9. However, in order to facilitate the disassembly of the support frame 3, as shown in FIG. Figure 1 As shown, the connecting seat 9 and the support shaft 15 are connected via a flange 8;

[0025] like Figure 1 As shown, each support shaft 15 is rotatably mounted in a bearing seat 7 , and the bearing seats 7 are respectively arranged on the top of the bracket 2 .

[0026] like Figure 1 As shown, a driving mechanism connected to the support shaft 15 is installed on the side of at least one bracket 2, and the driving mechanism is used to drive the support table to rotate. The specific structure of the driving mechanism includes a gear box 6 connected to the support shaft 15. The gear box 6 is arranged on the bracket 2 and its input end is connected to the drive motor 5.

[0027] The most important thing about this application is that there are multiple workpiece stations on the support table, so the workpiece stations can also rotate with the support table;

[0028] like Figure 2As shown, each workpiece station includes at least one guide rail 12 installed on the support table, and each guide rail 12 has a matching slider 11 slidably installed at both ends. It should be noted that there are no unlimited devices at both ends of the guide rail 12, and the slider 11 can be directly pulled out from the end of the guide rail 12, or directly inserted from the end of the guide rail 12, which is convenient for disassembly and installation of the slider 11. A positioning bolt 21 is provided on each slider 11 for positioning it. Tightening the positioning bolt 21 can make it abut against the surface of the guide rail 12, that is, the slider 11 can adjust its position along the guide rail 12, and after adjusting to the preset position, it can be fixed by the positioning bolt 21.

[0029] Each slider 11 is provided with a pneumatic clamping portion at the top, which includes a first strip plate 19 perpendicular to the support table, a second strip plate 20 provided on the side of the first strip plate 19, and an adjustment groove 18 provided on the side of the second strip plate 20 and the first strip plate 19. The adjustment groove 18 is provided with a bolt for fastening the two. The second strip plate 20 is vertically mounted on the top of the slider 11. When the bolt is loosened, the height of the first strip plate 19 can be adjusted. When the first strip plate 19 is adjusted to the preset height, it can be tightened by the bolt.

[0030] The pneumatic clamping part also includes a first support arm 16 and a second support arm 17. Figure 2 As shown, one end of the first support arm 16 and the second support arm 17 are connected and the two form a "V"-shaped structure, the "V"-shaped structure is open upward and its bottom is rotatably connected to the top of the first strip plate 19;

[0031] During actual use, the second support arm 17 is faced to the workpiece, and the other end of the first support arm 16 is rotatably connected to the cylinder 13. The cylinder 13 is installed on the cylinder support 14. The cylinder support 14 is located on the side of the first strip plate 19 and the two are rotatably connected. Therefore, when the cylinder 13 is extended and retracted, it can drive the "V"-shaped structure to rotate around the top of the first strip plate 19, so that the second support arm 17 is close to or away from the workpiece. A support 24 is provided on the end of the second support arm 17. The support 24 moves with the movement of the second support arm 17. The support 24 is against the side of the workpiece or pressed on the edge of the workpiece, so that the workpiece can be clamped.

[0032] The present application also provides a support structure for the workpiece. When processing the workpiece, the workpiece can be directly placed on the support structure. The support structure includes a carrier 10 provided on the top of each workpiece station, and sliders 11 are distributed at both ends of the carrier 10. When in use, the slider 11 is adjusted to approach the end of the carrier 10 so that the second support arm 17 is located on the side of the workpiece. The control cylinder drives the second support arm 17 to rotate to clamp the workpiece placed on the carrier 10.

[0033] Further improvements have been made to the carrier platform, such as Figure 3As shown, a limiting flange 22 is provided at the top edge of the supporting platform 10, and the workpiece is placed in the cavity formed by the limiting flange 22, that is, the workpiece is placed in the cavity to be positioned; a plurality of support legs 23 are provided at the edge of the supporting platform 10, and the support legs 23 are connected to the supporting table surface, and the support legs 23 are specifically fastened to the mounting plate 4 by bolts.

[0034] To sum up, when the present application is in use, the multiple workpiece stations set on the mounting plate 4 can correspond to the placement of multiple workpieces, that is, each workpiece can be placed on the supporting platform, and then the extension of each cylinder 13 is controlled to drive the end of the second support arm to rest on the workpiece to fix it, and the driving motor 5 can drive the workpiece station to rotate, allowing the workpiece to tilt, which is convenient for multi-angle processing.
