Table clamps are usually made of metal and have high strength and stability. They are widely used in the fields of machining, assembly, welding, measurement, etc. In the current technical solutions, air cylinders are often used as driving components to drive the movement of the table clamp to adapt to the processing requirements of equipment with different shapes and sizes. However, when using an air cylinder for driving, not only is the air cylinder prone to damage due to frequent actions, but also the extended length of the air cylinder cannot be controlled, and thus the position of the table clamp cannot be accurately controlled.

[0017] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0018] In order to better understand the above - mentioned technical solutions, the exemplary embodiments of the present utility model will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0019] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0020] Please refer to Figure 1 , an embodiment of the present utility model provides a turntable clamp driving mechanism, which can accurately control the position of the turntable clamp to adapt to the processing requirements of equipment with different sizes and shapes.

[0021] The turntable clamp driving mechanism includes a base plate 100, a movable plate 200, and a rotary driving assembly. Specifically, the base plate 100 can be a plate-like structure of any shape, and there can be multiple mounting positions on the base plate 100 for mounting other components. A first slide rail 110 is provided on the base plate 100, and the movable plate 200 is slidably disposed on the first slide rail 110. The movable plate 200 can reciprocate along the first slide rail 110 under the drive of an external force.

[0022] One end of the movable plate 200 is connected to a turntable clamp 210. When the movable plate 200 reciprocates on the first slide rail 110, the turntable clamp 210 is correspondingly driven to move, thereby realizing the adjustment of the position of the turntable clamp 210.

[0023] The rotary driving assembly is disposed on the base plate 100. The rotary driving assembly includes a rotary driving member 310 and a transmission unit. The two ends of the transmission unit are respectively connected to the rotary driving member 310 and the movable plate 200. The transmission unit can drive the movable plate 200 to reciprocate along the first slide rail 110 under the drive of the rotary driving member 310, thereby realizing the adjustment of the position of the turntable clamp 210. That is to say, the transmission unit can convert the rotary motion of the rotary driving member 310 into the linear motion of the movable plate 200. Thus, the staff can accurately control the position of the turntable clamp 210 by controlling the rotary motion of the rotary driving member 310.

[0024] In one embodiment, the transmission unit includes a first connecting rod 321 and a second connecting rod 322. One end of the first connecting rod 321 is vertically connected to the output shaft of the rotary driving member 310. Specifically, the rotary driving member 310 can be disposed in the vertical direction, and the end of the first connecting rod 321 is perpendicular to the output shaft of the rotary driving member 310, so that the first connecting rod 321 can rotate on the horizontal plane under the drive of the output shaft. The other end of the first connecting rod 321 is rotatably connected (such as hinged) to one end of the second connecting rod 322, and the other end of the second connecting rod 322 is connected to the movable plate 200.

[0025] Thus, since the first link 321 and the second link 322 are rotatably connected, when the first link 321 rotates driven by the output shaft of the rotary drive member 310, it will not drive the second link 322 to rotate together, but will "pull" the second link 322. At this time, due to the limitation of the first slide rail 110 on the movable plate 200, the second link 322 can drive the movable plate 200 to reciprocate along the first slide rail 110. It should be understood that when the rotation direction of the first link 321 changes, the movement direction of the movable plate 200 will also change accordingly.

[0026] In an embodiment of the present invention, the transmission unit further includes a bearing 323. A second slide rail 321-A is provided along the length direction at the top of the first link 321. The bearing 323 is slidably disposed on the second slide rail 321-A, and the inner ring of the bearing 323 is connected to the end of the second link 322. Thus, through the setting of the bearing 323, when the first link 321 rotates, the side wall of the second slide rail 321-A applies a force to the bearing 323. Under the action of the force applied by the side wall of the second slide rail 321-A to it and the pulling force of the second link 322 on it, the bearing 323 reciprocates along the second slide rail 321-A, thereby driving the second link 322 to move. In this way, the rigid connection between the first link 321 and the second link 322 can be avoided, and on the basis of ensuring the function of the transmission unit, the service life of the transmission unit is extended.

[0027] In an embodiment, an anti-detachment structure is provided at the end of the second slide rail 321-A close to the second link 322 to limit the bearing 323 and prevent the bearing 323 from detaching from the second slide rail 321-A. In an example, the anti-detachment structure may be a convex block or a convex point provided at the end of the second slide rail 321-A close to the second link 322. It should be understood that those skilled in the art can select the corresponding anti-detachment structure according to actual implementation needs, and no special limitation is made thereto.

[0028] In an embodiment, the rotary drive member 310 is disposed on the bottom surface of the substrate 100, and its output shaft passes through the substrate 100 from bottom to top to be connected to the first link 321. It should be understood that by disposing the rotary drive member 310 on the bottom surface of the substrate 100, there is no need to provide a complex installation structure to avoid the first link 321, saving the equipment cost.

[0029] In an example, the rotary drive member 310 may be a servo motor. It should be understood that a servo motor is a precision motor that can convert the input electrical signal into mechanical motion and can precisely control the angular displacement or angular velocity of the motor shaft, so as to precisely control the position of the table clamp 210.
