During the movement of the robotic arm, due to the hard connection between the structures, there may be reaction forces in multiple directions, and the robotic arm has a risk of being damaged. Therefore, how to prevent the robotic arm from being damaged by reaction forces during operation has become an urgent problem to be solved in the enterprise production process. Summary of the Utility Model

[0016] The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0017] Embodiment

[0018] As Figures 1 - 3 shown, the cylinder clamping mechanism of the present utility model includes a cylinder fixing seat for fixing the cylinder 5. A clamping mechanism is connected to the telescopic rod 3 of the cylinder 5.

[0019] The cylinder fixing seat includes a first fixed seat 6 and a second fixed seat 4, which are respectively fixed at the front and rear ends of the cylinder 5. The first fixed seat 6 and the second fixed seat 4 are fixedly connected to the robotic arm, playing the role of fixing the cylinder 5 and fixing the cylinder 5 at the end of the robotic arm.

[0020] The clamping mechanism includes a first clamping seat 1 and a second clamping seat 2. The air cylinder 5 includes a telescopic rod 3, and the end of the telescopic rod 3 is fixedly connected to the second clamping seat 2. The second clamping seat 2 has a conical structure. The first clamping seat 1 includes a connecting end 11 and a clamping end 12. The connecting end 11 is fixed on the object that needs to float; an opening is provided on the clamping end 12, and it is sleeved outside the telescopic rod 3 through the opening and is located between the second clamping seat 2 and the second fixing seat 4. One side of the clamping end 12 of the first clamping seat 1 close to the second clamping seat 2 can be fitted and installed with the conical surface of the second clamping seat 2. One side of the clamping end 12 of the first clamping seat 1 close to the second fixing seat 4 can be fitted and installed with the round hole opened on the second fixing seat 4. When the telescopic rod 3 of the air cylinder 5 expands and contracts, the second clamping seat 2 can move with the telescopic rod 3 to clamp or loosen the first clamping seat 1; when in the clamped state, the second clamping seat 2, the first clamping seat 1 and the second fixing seat 4 are in contact with each other.

[0021] The cylinder clamping mechanism of the present utility model is mainly used for collaborative robots and is installed on the robotic arm through a cylinder fixing seat. During the movement of the robotic arm, the telescopic rod 3 of the air cylinder 5 is controlled to expand and contract by a solenoid valve to pull the second clamping seat 2, as Figure 3 shown, pressing the first clamping seat 1 against the second fixing seat 4 of the air cylinder 5; when the robotic arm needs to drive the object to move, the air cylinder 5 contracts, and the first clamping seat 1 is fixed and can move with the robotic arm; as Figure 2 shown, when the object moves to the corresponding position, the air cylinder 5 extends, and the first clamping seat 1 is in a floating state. During the operation of the object, the acting force will not be transmitted to the robotic arm, and thus the mutual conversion between floating and clamping can be achieved.

[0022] The cylinder clamping mechanism of the present utility model realizes the mutual conversion between the floating and clamping states between the air cylinder and the robotic arm by setting the clamping mechanism, which can protect the robotic arm from the acting force of hard connection and prevent the reaction force from damaging the robotic arm during the operation of the robotic arm.

[0023] Although the present utility model has been described in detail above with general descriptions and specific embodiments, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope claimed by the present utility model.
