[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0020] See also Figure 1 and Figure 2 The cylinder linkage clamping device comprises a cylinder 1, a linkage mechanism 2 and a clamp 3. The cylinder 1 is connected to two clamps 3 through the linkage mechanism 2. The cylinder 1 can drive the two clamps 3 to move toward or away from each other through the linkage mechanism 2 to complete the clamping or releasing action, thereby reducing the equipment cost of the clamping device.

[0021] In some embodiments, the linkage mechanism 2 includes a slide rail 21 , the two clamps 3 are slidably connected to the slide rail 21 , and the cylinder 1 is disposed on the slide rail 21 to drive the clamps 3 to slide along the slide rail 21 .

[0022] In some embodiments, the linkage mechanism 2 further includes two connecting rods 22 and a connector 23, one end of the two connecting rods 22 is rotatably connected to the two clamps 3 respectively, the other end of the two connecting rods 22 is rotatably connected to the connector 23, and the connection positions of the two connecting rods 22 on the connector 23 are different. The cylinder 1 is transmission-connected to one of the clamps 3, driving the clamp 3 to move along the slide rail 21. When the clamp 3 moves, the connector 23 is driven to rotate through the connecting rod 22, and the other clamp 3 is driven to move symmetrically through the other connecting rod 22, thereby achieving the action of clamping or releasing.

[0023] In some embodiments, the linkage mechanism 2 further includes a connecting shaft 24, the upper end of which is fixedly connected to the slide rail 21, and the lower end of which is rotatably connected to the connector 23. The connecting shaft 24 serves to connect and stabilize the connector 23.

[0024] In a preferred embodiment, the connecting rod 22 is an arc-shaped rod, and the middle part of the arc-shaped rod can bypass the connecting shaft 24 to avoid interference with the connecting shaft 24, so that Figure 2 Similarly, the two connecting rods 22 and the connecting shaft 24 are in the same straight line. In this way, the length of the connecting rod 22 can be used to the maximum extent. When the length of the connecting rod 22 along the slide rail 21 is constant, a larger stroke of the clamp 3 is obtained compared to the straight rod. In other words, in order to achieve a certain stroke of the clamp 3, the length of the arc rod along the slide rail 21 is shorter than that of the straight rod, thereby reducing the length of the clamping device.

[0025] In some embodiments, the position where the lower end of the connecting shaft 24 is connected to the connector 23 is located at the center of the line connecting the connection positions of the two connecting rods 22 and the connector 23. The connector 23 can be elliptical or diamond-shaped or other shapes.

[0026] In some embodiments, the linkage mechanism 2 further includes a return torsion spring 25, which is sleeved on the connecting shaft 24, and the upper end of the return torsion spring 25 is connected to the slide rail 21, and the lower end is connected to the connector 23. The return spring 25 provides elastic force to make the clamp 3 clamp tighter.

[0027] In some embodiments, the linkage mechanism 2 also includes a connecting plate 26, the two ends of the connecting plate 26 are respectively fixedly connected to the two slide rails 21, the two clamps 3 are respectively arranged on the two slide rails 21, the upper end of the connecting shaft 24 is fixedly connected to the connecting plate 26, and the upper end of the reset torsion spring 25 is fixedly connected to the connecting plate 26.

[0028] In some embodiments, the linkage mechanism 2 further includes a protective shell 27, which is fixedly connected to the connecting plate 26 and encloses a protective cavity. The connector 23, the connecting shaft 24 and the return torsion spring 25 are built into the protective cavity, and the connecting rod 22 extends out of the protective cavity. Figure 1 The middle protective shell 27 is a cross-sectional view to show the connection relationship between the internal connector 23, the connecting shaft 24 and the return torsion spring 25.

[0029] In some embodiments, the clamp 3 includes a clamp seat 31 and a clip 32. The clamp seat 31 is slidably connected to the slide rail 21. The clamp seat 31 has a mounting groove. The clip 32 is detachably connected to the mounting groove. Different clips 32 can be replaced according to different workpieces to be clamped.

[0030] In some embodiments, the cylinder 1 is drivingly connected to one of the clamping seats 31 .

[0031] Compared with the prior art, the cylinder linkage clamping device provided by the utility model utilizes a linkage mechanism to connect one cylinder with two clamps, so that one cylinder can drive the two clamps to move toward or away from each other at the same time, thereby reducing the equipment cost of the clamping device.
