[0014] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0015] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The present invention provides the following technical solutions: Embodiment 1: Combination Figures 1 to 4 , a hydraulic turning mechanism of a workbench, comprising a gear box body 1 and a workbench 3, wherein a turning mechanism 2 is arranged on the gear box body 1; 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, and 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. A gear 22 is meshedly connected to the right side of the rack 21. 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 arranged on the surface of the rotating rod 201. The lower side surface of the gear 22 is fixedly connected to the inside of the workbench 3. A connecting block 29 is fixedly connected to the surface of the rotating shaft 23. 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. 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, 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, 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 penetrated and inserted into the through hole groove opened inside the gear box body 1.

[0017] 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, and the rack 21 drives the gear 22 to rotate, thereby driving the workbench 3 to flip 180°. Compared with the commonly used flipping structure of the motor + reducer driving the workbench 3 to flip, this flipping mechanism 2 has the advantages of large flipping torque and adjustable flipping speed (the linear motion speed of the hydraulic cylinder 26 is adjusted by the hydraulic system to achieve the adjustment of the flipping speed).

[0018] In actual operation, when this device is used, the hydraulic cylinder 26 drives the connecting flange 24 to move, 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. When the rotating shaft 23 rotates, it can drive the workbench 3 to rotate, so that the workbench 3 can be turned 180°, and with the cooperation of the bearing 27 and the flat key 28, it can be more stable when driven by the rotating shaft 23. This turning mechanism 2 has the advantages of large turning torque and adjustable turning speed compared to the commonly used turning structure of the motor + reducer driving the turning of the workbench 3 (the turning speed is adjusted by adjusting the linear motion speed of the hydraulic cylinder 26 through the hydraulic system).
