[0007] The hinge seat, connecting rod, clamp, etc. are all installed on the rotating seat, and the rotating seat is installed on the rotating cylinder, and can rotate at a preset angle within the range of 0-180°; the rotating seat is connected to the rotating disk of the rotating cylinder, and the rotating cylinder is fixed on the sliding seat; the sliding seat is installed on the slider of the linear guide rail, and can move back and forth along the slide rail in a straight line; the linear guide rail and the linear cylinder are installed on the base, and the cylinder connecting rod is connected to the sliding seat, and with the reciprocating linear motion of the cylinder rod, the sliding seat is driven to move along the linear guide rail.

[0008] Furthermore, in order to better realize the utility model, the swing arm is installed on the fixed hinge shaft seat, and the movable hinge shaft seat is installed on the cylinder rod of the clamping cylinder and is connected to the swing arm through a connecting rod.

[0009] Furthermore, in order to better realize the present invention, one end of the connecting rod is connected to the rocker arm, and the other end is connected to the movable hinge shaft seat. The cylinder rod of the clamping cylinder and the movable hinge shaft seat telescope forward and backward, and then the rocker arm is driven by the connecting rod to rotate and swing within a certain angle around the fixed hinge shaft seat, thereby realizing the clamping and releasing action.

[0010] Furthermore, in order to better implement the present invention, the first clamp and the second clamp are arranged in staggered layers, and a set of clamps can clamp objects of different specifications and shapes without changing the jaws, thereby improving the application range of the clamps.

[0011] The beneficial effects of the utility model are:

[0012] The device of the utility model uses a connecting rod mechanism and combines the application of a rotary cylinder to simplify the transmission structure and realize the functions of opening and closing, rotating, and changing the clamping position of the clamp. Under the premise of ensuring durability and stability, the application range and action continuity of the clamp are improved within the effective space, thereby improving work efficiency and promoting automation.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] Figure 1This is a specific embodiment of the utility model, which is a retractable pneumatic rotating connecting rod clamp, and the specific use method is:

[0022] The clamping cylinder 7 and the fixed hinge seat 10 are respectively installed on the rotating seat 6, the fixed hinge seat 10 is arranged on both sides of the clamping cylinder 7, and the movable hinge seat 8 is connected to the cylinder rod of the clamping cylinder 7. The swing rod 11 is connected to the fixed hinge seat 10 through the hinge shaft, and one end of the connecting rod 9 is connected to the hinge shaft of the movable hinge seat 8, and the other end is connected to the hinge shaft of the swing rod 11. As the cylinder rod of the clamping cylinder 7 and the movable hinge seat 8 move forward and backward, the swing rod 11 is driven by the connecting rod 9 to swing around the hinge shaft hole of the fixed hinge seat 10 within a certain angle, thereby realizing the clamping and releasing actions.

[0023] The other side of the rotating seat 6 is installed on the rotating disk of the rotating cylinder 5, and can rotate with the rotating disk at a preset angle within the range of 0-180°. The rotating cylinder 5 and the connected rotating seat 6 are fixedly installed on the slider of the linear guide 4 through the sliding seat 3. The sliding seat 3 is connected and fixed to the cylinder rod of the linear cylinder 2. Under the action of the linear cylinder 2, the sliding seat 3, the rotating cylinder 5, the clamp, etc. can reciprocate forward and backward along the linear guide 4 on the base 1, thereby adjusting the working position of the clamp.

[0024] Since the first clamp 12 and the second clamp 13 are arranged in staggered layers, different clamps can be used to clamp objects of different shapes or specifications under different use conditions, thereby increasing the application range of the clamps, reducing the frequency of clamp replacement, and improving efficiency.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
