[0024] In an automated assembly line, workpieces are clamped by fixtures and can be rotated and adjusted in time on a positioner. A flipping mechanism is used to drive the fixture or workpiece for rotational adjustment. After completing a pre-designed process at one station, the flipping mechanism, along with the fixture and workpiece, is driven by a moving mechanism to move the entire system to the next station, where the workpiece is then manipulated by the operating components.

[0025] The specific operation method relies on the sliding guidance of the guide rail 3 and the slider 4. The output shaft of the drive motor 7 rotates to drive the drive gear 6 to rotate. The drive gear 6 rotates and can move on the rack 5 engaged with it, thereby driving the moving seat 2 to move along the guide direction of the guide rail 3 and the slider 4. This driving method is stable and controllable. The output of the drive motor 7 is adjusted by servo control and the like to achieve precise adjustment of the position of the moving seat 2.

[0026] The flipping mechanism includes a flipping table 8 and a support table 9. The number of the movable seat 2 is two, and the flipping table 8 and the support table 9 are respectively installed on the movable seat 2. The flipping table 8 and the support table 9 are used to install the fixture plate 10 for placing the workpiece. The flipping table 8 mainly plays the role of rotation and displacement drive. A flipping and displacement motor is usually installed on the flipping table 8 to drive the rotation of the fixture plate 10. The support table 9 is used to cooperate with the flipping table 8 to clamp the fixture plate 10 and to support the fixture plate 10 to ensure that the fixture plate 10 is flipped and displaced stably and reliably. In addition, the flipping table 8 and the support table 9 are both installed on the movable seat 2, which can ensure that the two can move synchronously along the direction of the guide rail 3. On the other hand, the mutual distance between the flipping table 8 and the support table 9 can be adjusted in time according to the size of the fixture plate 10, thereby increasing the applicability of the flipping mechanism.

[0027] The turning table 8 is provided with a quick-change connection device for quick-change connection of the fixture plate 10, including a flange 11 and a connecting plate 12. The flange 11 is provided with a plurality of connecting holes 13. The connecting plate 12 is fixedly connected to the flange 11 through some of the connecting holes 13.

[0028] A guide block 14 is fixedly provided on the connecting plate 12, and a guide groove cooperating with the guide block 14 is provided on the clamping plate 10; the clamping plate 10 and the connecting plate 12 are quickly connected by a positioning mechanism, a pre-tightening mechanism and a fixing mechanism.

[0029] This fixture quick-change connection device allows the fixture to be quickly installed on the positioner, achieving rapid positioning and clamping of the fixture plate 10 and the flange 11 on the positioner. The multiple connection holes 13 distributed on the flange 11 provide different installation positions for the connecting plate 12 to accommodate different fixture installation sizes. During operation, the connecting plate 12 is first installed on the corresponding position on the flange 11 according to the different fixture specifications and models, completing the positioning and fixing of the connecting plate 12 and the flange 11.

[0030] Then install the fixture plate 10 and the connecting plate 12. The connecting plate 12 plays the role of transition connection. During the installation process of the fixture plate 10 and the connecting plate 12, the guide block 14 plays the role of preliminary guidance. By inserting the guide block 14 into the guide groove, this preliminary positioning can guide the pre-positioning connection of the fixture plate 10 and the connecting plate 12. After completing the preliminary positioning, the final positioning and fixed connection installation of the fixture plate 10 and the connecting plate 12 are completed through the positioning mechanism, pre-tightening mechanism and fixing mechanism.

[0031] The positioning mechanism includes a positioning pin 15 installed on the fixture plate 10 and a positioning sleeve 16 installed on the connecting plate 12. The fixture plate 10 is provided with a pin positioning hole 17, and the positioning pin 15 is inserted into the pin positioning hole 17; the connecting plate 12 is provided with a sleeve positioning hole 18, and the positioning sleeve 16 is inserted into the sleeve positioning hole 18; the bottom of the positioning pin 15 is inserted into the inner hole of the positioning sleeve 16.

[0032] The positioning mechanism realizes the precise positioning of the fixture plate 10 and the connecting plate 12 after the guide block 14 and the guide groove complete the initial positioning. During positioning, the positioning pin 15 is inserted into the inner hole of the positioning sleeve 16 to complete the positioning connection. The positioning method using the positioning pin 15 and the positioning sleeve 16 has a high positioning accuracy, and when the connection method is contacted, the release of the positioning connection is also convenient and quick.

[0033] The pre-tightening mechanism includes a pivot bolt 19 installed on the connecting plate 12 and rotatably installed by a turn pin. A locking groove 20 is provided on the clamp plate 10 at a position corresponding to the pivot bolt 19. The locking groove 20 is an open groove 21. The pivot bolt 19 is inserted into the open groove 21. A pivot nut 22 is installed on the pivot bolt 19, and the pivot nut 22 is locked on the clamp plate 10.

[0034] The pre-tightening device is used to clamp and fix the connecting plate 12 and the clamp plate 10 after the positioning mechanism completes the precise positioning. The swing bolt 19 can be rotated around the swivel pin so that it can be installed into the locking groove 20 or removed from the locking groove 20. When the positioning is completed, the swing bolt 19 is rotated to fit into the locking groove 20, and then the swing nut 22 is screwed into and installed on the swing bolt 19, so that the locking connection between the clamp plate 10 and the connecting plate 12 can be completed; when the connection needs to be removed, it is also necessary to unscrew the release swing nut 22. After the swing nut 22 is released from the swing bolt 19, the swing bolt 19 can be rotated and removed from the locking groove 20, so that the fixed pre-tightening of the pre-tightening device can be released.
