[0011] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0012] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0013] Examples, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a rotating bar assembly fixture, including a fixture base 1, a pair of columns 2 on the fixture base 1, and supports 3 arranged in a triangular pattern with the columns 2 on the fixture base 1. The supports 3 have a portal-shaped structure and a base plate 4 at their bottom. A pair of sliding plates 5 are arranged on both sides of the supports 3, and a pair of bearing seats 6 are arranged between the sliding plates 5. Bearings 7 are arranged inside the bearing seats 6, and the center of the bearings 7 is used to cooperate with the rotating bar 8. A motor seat 9 is arranged on one of the bearing seats 6 facing the column 2. A servo motor 10 is arranged at the end of the motor seat 9. A connector 11 is arranged at the power output end of the servo motor 10. The connector 11 is used to drive the end of the rotating bar 8. A lifting device 12 is arranged on the side of the sliding plate 5. The lifting device 12 is used to drive the sliding plate 5, the servo motor 10 and the rotating bar 8 to lift synchronously.

[0014] Specifically, the column 2 on the tooling base 1 increases the overall weight of the tooling, which helps improve the balance of the device during assembly; the portal design of the support 3 not only provides an installation base for the bearing seat 6, but also provides clamping space for the rotating rod 8; the servo motor 10 provides rotational power and direction to the connector 11 and the rotating rod 8, so that the rotating rod 8 can be matched to the corresponding assembly angle; the lifting device 12 is used to adjust the height of the rotating rod 8 to match the hydraulic components to be assembled with it. Inserting the rotating rod 8 from the bearing 7 into the connector 11, the servo motor 10 drives the connector 11 to rotate the rotating rod 8, reducing the assembly difficulty of the rotating rod 8, and the lifting action of the lifting device 12 can adjust the assembly height in real time, which helps improve the assembly accuracy. This provides a dedicated tooling for assembling the rotating rod 8 to improve the efficiency of the assembly operation, which is highly practical and has a high utilization rate.

[0015] To improve the adjustment performance of the lifting device 12, the lifting device 12 provided by this utility model includes a lifting chain 121. One end of the lifting chain 121 is provided with a lifting connecting plate 122, which is connected to the slide plate 5. The other end of the lifting chain 121 is provided with a fixed connecting plate 123, which is disposed on a side plate 13. The side plate 13 is disposed on a bottom plate 4. A lifting cylinder 124 is disposed between the side plates 13. A sprocket seat 125 is disposed on the top of the lifting cylinder 124. A lifting sprocket 126 is disposed on the top of the sprocket seat 125. The top of the lifting sprocket 126 is in transmission cooperation with the lifting chain 121. The fixed end of the lifting cylinder 124 is connected to the base plate 4, and its telescopic end faces upward. The lifting cylinder 124 is used to lift the sprocket seat 125 upward. The lifting sprocket 126 on the sprocket seat 125 can rotate along the lifting chain 121. Since the total working length of the lifting chain 121 remains unchanged and one end is fixed by the fixed connecting plate 123, the other end of the lifting chain 121, namely the lifting connecting plate 122, works with the slide plate 5, bearing seat 6 and rotating rod 8 to change its height, thereby adjusting the assembly height of the rotating rod 8, which is beneficial to improving the assembly efficiency.

[0016] To facilitate adjustment of the assembly angle of the rotating lever 8, this invention provides flipping shafts 14 on both sides of the side plate 13. The flipping shafts 14 are mounted on shaft support seats 15, which are in turn mounted on the tooling base 1. A pair of first fixed hinge seats 16 are provided on the base plate 4 near the column 2. A flipping cylinder 17 is mounted on each of the first fixed hinge seats 16, and the telescopic end of the flipping cylinder 17 is axially connected to a second fixed hinge seat 18 located on the side of the column 2. When the telescopic end of the flipping lever 8 moves, its hinged design allows for planar motion, thereby causing the base plate 4 and support 3 to flip around the flipping shaft 14, resulting in a corresponding angle adjustment. This achieves the purpose of adjusting the assembly angle of the rotating lever 8, which helps improve assembly accuracy.

[0017] To improve the balance of the sliding plate 5 during translational movement along the height direction of the support 3, the sliding plate 5 of this utility model is provided with four guide posts 51 symmetrically distributed in pairs. The guide posts 51 cooperate with the guide rails 31 set on the support 3. Two parallel guide rails 31 are set on both sides of the support 3, and the guide posts 51 located in the same vertical direction cooperate with one guide rail 31. When the lifting device 12 generates lifting action, the sliding surface of the sliding plate 5 and the support 3 has multiple nodes to complete the translational cooperation, thereby improving the lifting balance of the sliding plate 5.

[0018] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
