[0020] 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.

[0021] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0022] The utility model provides the following technical solutions:

[0023] Example 1: Combination Figures 1 to 4 A hydraulic turning mechanism for a workbench comprises a gear box 1 and a workbench 3, wherein a turning mechanism 2 is provided on the gear box 1;

[0024] The flip mechanism 2 includes a hydraulic cylinder 26, which is fixedly connected to the left side of the front face of the gear box 1. A connecting flange 24 is fixedly connected to the bottom of the hydraulic cylinder 26. A rack 21 is fixedly connected to the bottom of the connecting flange 24. A guide plate 25 is fixedly connected to the left side of the front face of the gear box 1. The right side of the rack 21 is meshed with a gear 22. A rotating rod 201 is fixedly connected to the axis of the gear 22. A connecting block 29 is fixedly connected to the bottom of the rotating rod 201. A rotating shaft 23 is fixedly connected to the top of the connecting block 29. The rotating shaft 23 is provided on the surface of the rotating rod 201. The lower surface of the gear 22 is fixedly connected to the inside of the workbench 3. The surface of the rotating shaft 23 is fixedly connected to the connecting block 29. Bearings 27 are fixedly connected to the upper and lower surfaces of the gear box 1, and flat keys 28 are fixedly connected to both sides of the inner wall of the gear box 1.

[0025] The workbench 3 is arranged on the back of the gear box body 1, the connecting block 29 is arranged on the back of the workbench 3, a slide groove is opened inside the guide plate 25, and the left side of the rack 21 is slidably connected to the slide groove opened inside the guide plate 25. There are two bearings 27, and the two bearings 27 are arranged on both sides of the flat key 28. The bearings 27 are sleeved on the upper and lower sides of the surface of the rotating shaft 23. The flat key 28 is arranged at the center of the surface of the rotating shaft 23. A through hole groove is opened inside the gear box body 1, and the surface of the rotating shaft 23 is inserted into the through hole groove opened inside the gear box body 1.

[0026] Furthermore, the gear 22 is connected to the workbench 3 as a whole through the flat key 28, the rotating shaft 23, the rotating rod 201, and the connecting block 29. This flipping mechanism 2 abandons the commonly used form of motor + reducer driving the workbench 3 to flip, and adopts the hydraulic cylinder 26 to drive the rack 21 to make a linear reciprocating motion. The rack 21 then drives the gear 22 to rotate, thereby driving the workbench 3 to flip 180°. This flipping mechanism 2 has the advantages of large flipping torque and adjustable flipping speed compared to the commonly used flipping structure of motor + reducer driving the workbench 3 to flip (the adjustment of the flipping speed is achieved by adjusting the linear motion speed of the hydraulic cylinder 26 by the hydraulic system).

[0027] In actual operation, when this device is used, the hydraulic cylinder 26 drives the connecting flange 24 to move under the operation of the hydraulic cylinder 26, and the connecting flange 24 drives the rack 21 to move. Since the rack 21 and the gear 22 are meshed and connected, the gear 22 rotates. When the gear 22 rotates, it can drive the rotating rod 201 to rotate, and the rotating rod 201 drives the connecting block 29 to move. At this time, the connecting block 29 can also drive the rotating shaft 23 to rotate. Under the rotation of the rotating shaft 23, the workbench 3 can be driven to rotate, which can make the workbench 3 rotate 180°, and with the cooperation of the bearing 27 and the flat key 28, it can be more stable under the rotation driven by the rotating shaft 23. This flipping mechanism 2 has the advantages of large flipping torque and adjustable flipping speed compared to the commonly used flipping structure of the motor + reducer driving the workbench 3 to flip (the flipping speed is adjusted by adjusting the linear motion speed of the hydraulic cylinder 26 by the hydraulic system).

[0028] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
