Problems solved by technology
[0003] The technical problem to be solved by the present invention is: in order to solve the clamping or loosening of the parts by the two claws of the existing robot relatively open or relatively close together, when the claws are grasping, due to the external force acting on the parts When it is put on, the part exerts a reverse force on the jaws, and it is easy to make the jaws relatively open, which will cause the parts to fall and be damaged, increase the production cost, and cause serious injuries to the staff. Now a kind of problem is provided. Self-locking gripper mechanism for robots

Embodiment
[0023] Such as Figure 1-8 As shown, a self-locking gripper mechanism for a robot includes a base 1 and a claw 2 arranged on the base 1, and also includes a limit post 3, a baffle plate 4 and a first elastic element 5. There are two claws 2 which are oppositely arranged, and the two claws 2 are all rotatably arranged on the base 1, and a chute 6 is opened on the base 1, and the chute 6 has an upper end guide which is sequentially terminated and connected. Section 601, limit section 602 and lower end guide section 603 form a closed ring structure. The upper end guide section 601 has a first slope that is gradually inclined upward along the rotation direction when the claw 2 is opened, and the first slope is located near the limit. One side of the position segment 602, the limit segment 602 is arranged in the vertical direction, the limit segment 602 is provided with a number of spines 7, the spine 7 has a displacement segment 701 and a blocking segment 702 connected in sequence...

The invention relates to the technical field of robots, in particular to a self-locking gripper mechanism used for a robot. The self-locking gripper mechanism used for the robot comprises a bas and two clamping jaws arranged on the base. The self-locking gripper mechanism used for the robot further comprises limiting columns, baffles and first elastic elements. The two clamping jaws are arranged oppositely and both rotatably arranged on the base. Sliding grooves are formed in the base. Each sliding base is provided with an upper end guiding section, a limiting section and a lower end guiding section, wherein the upper end guiding section, the limiting section and the lower end guiding section are sequentially connected end to end to form a closed annular structure. When the self-locking gripper mechanism used for the robot is in use, the limiting columns on the clamping jaws are matched with the sliding grooves; on the one hand, in a clamping state, the clamping jaws are forced to be opened under the effect of external force, the limiting columns abut against the blocking sections of thorns, then the clamping jaws cannot be opened, and the clamping jaws are kept in the clamping state; and on the other hand, when a driving device fails, the clamping jaws can still clamp a part, and stable and reliable clamping of the clamping jaws can be ensured.
Description
technical field [0001] The invention relates to the technical field of robot equipment, in particular to a self-locking gripper mechanism for a robot. Background technique [0002] Robots have been used in various important occasions to grab objects, transfer objects or process parts through robots. The existing robot realizes the clamping or loosening of the parts by opening or closing the two claws relatively. When the claws are grasping, when the external force acts on the parts, the parts exert a reaction on the claws. It is easy to cause the claws to open relatively, which will cause the parts to fall and be damaged, increase the production cost, and in serious cases cause the staff to be injured. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing robot realizes the clamping or loosening of the parts by relatively opening or closing the two claws, when the claws are graspi...
