Description

Technical Field

[0001] The utility model relates to the technical field of anti-stuck devices, in particular to an air claw anti-stuck component. Background Art

[0002] The air gripper is a kind of modern manipulator with a two- to five-finger gripping structure at the gripping end. The more coupling structures it has, the more flexible the claw shape is, and the more complex the gripping work it can complete. The biggest difference between it and ordinary mechanical grippers is that it is driven by pneumatic drive. Unlike ordinary motor-driven or hydraulic-driven manipulators, its structure is bidirectional and flexible and has various forms. It can be used in a variety of occasions, can realize a variety of gripping functions, and adapt to different clamping operations. It can also be installed with detection equipment to achieve constant torque output. The size of the air gripper torque can be controlled by programming to achieve the effect of constant output torque. At present, constant torque output has become a major research direction of air grippers, which makes air gripper-type clamping equipment more and more stable and accurate.

[0003] Nowadays, most air grippers require a multi-structure composition for force transmission, so that the upper piston changes the force transmission direction of the lever, thereby realizing the structural clamping and releasing process of the air gripper. However, the composition of multiple components often leads to frequent failures. Since the air gripper mainly relies on the action of air pressure on the piston to do work on the required object, when part of the structure fails, it will affect the operation of other structures, making the whole structure unable to do work. Therefore, it is necessary to improve the structure of the air gripper, and improve the force transmission process at the upper end of the air gripper to a simple structure with fewer components, so that the force transmission is direct, and to avoid small failures in the force transmission process that cause the whole structure to be unable to operate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0020] Refer to Figure 1 , the main body is a central plate 6. A piston cylinder 5 is installed at the upper end of the central plate 6, and an attachment cover is assembled at the upper end of the piston cylinder 5. A connecting plate 4 is assembled at the upper end of the attachment cover. An air pressure port is provided at the corresponding position of the connecting plate 4 for connecting an air pressure delivery port. A connection port is provided in the middle of the connecting plate 4, and a connection block 1 is installed at the lower end of the connection port. A fixed port 8 is assembled at the connection port. The connection block 1 is embedded on the surface of the central plate 6 and assembled on the lower surface of the connecting plate 4. The lower end of the central plate 6 is connected to a centering ring 2 for calibrating the position of the lower pressure rod 3. A bearing plate 7 is assembled at the lower end of the centering ring 2. A perforation is provided on the surface of the bearing plate 7, and the lower pressure rod 3 is inserted into the perforation. The lower end of the lower pressure rod 3 is connected to a clamping mechanism. A central column is provided at the edge of the perforation and connected between the bearing plate 7 and the central plate 6 to provide a fixed connection effect for the bearing plate 7;

[0021] Refer to Figure 2 , the main body is a clamping mechanism. A lower pressure frame 10 is installed at the upper end of the clamping mechanism, and a lower pressure plate is assembled inside the lower pressure frame 10. A connecting bracket is installed inside the lower pressure frame 10 and connected to the lower surface of the bearing plate 7 to fix the lower pressure frame 10. The bottom opening of the lower pressure frame 10 is designed to be smaller and only allows a cylindrical structure to enter. When the lower pressure plate is pressed down to reach the bottom opening, it will be stopped. The main effect is to limit the pressing distance of the lower pressure rod 3. The lower pressure rod 3 is connected to the upper surface of the lower pressure plate. A clamping block 16 is installed at the lower end of the lower pressure frame 10, and a concave opening is provided on the upper surface of the clamping block 16. An inclined surface plate 15 is provided on one side of the concave opening;

[0022] Refer to Figure 3The main body is a lower pressure plate, and a pushing rod 13 is assembled at the lower end of the lower pressure plate, and a pushing column 12 is assembled at the lower end of the pushing rod 13. When the pushing column 12 is pushed downward, it will slide along the inclined plate block 15 and push the bottom clamping block 16 to deviate inwardly. The rotating column 9 connected at the upper end fixes the front end of the clamping block 16, so that the clamping block 16 can only rotate when subjected to thrust, thereby achieving the required clamping effect. The pushing column 12 is assembled inside the recessed mouth, and the rotating column 9 is inserted into the front end of the lower pressure frame 10, and the rotating column 9 is connected to the derivative block 14. A limit block 11 is provided on the other side of the recessed mouth. One side of the installation of the limit block 11 is used to limit the pulling back distance of the lower pressure rod 3, so that the lower pressure rod 3 will bring the bottom clamping block 16 back to its original position when it is pulled back, thereby achieving the loosening effect after clamping. The lower pressure rod 3 passes through the straightening ring 2 to the piston cylinder 5, and a fitting ring is assembled inside the piston cylinder 5, and a meshing layer is provided on the surface of the fitting ring.

[0023] During actual use, first connect the upper end of the device along the position of the connection port to the required mechanical parts, align the various air pressure delivery ports and connect them, and after completion, operate the control device to deliver air pressure inside. As the air pressure is delivered, the piston cylinder 5 is compressed and the internal fitting circle moves downward, driving the lower pressure rod 3 to be pressed downward. As the lower pressure rod 3 is pressed downward, the lower pressure plate is compressed, so that the bottom pushing column 12 is pushed along the inclined panel block 15, and the inclined panel block 15 is rotated inwardly due to the connection with the upper rotating column 9 when receiving the thrust, and the lower clamping block 16 performs a clamping operation. After the air pressure stops delivering, the pushing column 12 will bring the clamping block 16 back to its original position due to the design of the limit block 11. Since the device is simple in design at the force transmission point, it is very likely to avoid the situation of jamming in the middle, and the subsequent maintenance and processing are simple.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
