Description

Technical Field

[0001] The utility model relates to the technical field of robot grippers, in particular to a robot quick-change gripper. Background Art

[0002] A gripper is a robot component that can achieve functions similar to those of a human hand. A robot gripper is a component used to hold workpieces or tools and is one of the important actuators. According to the different shapes of the workpieces held by the robot, grippers can be divided into various types, mainly including three categories: mechanical grippers, also known as mechanical clamps, including two-finger, three-finger, and deformed fingers; special grippers including magnetic chucks, welding torches, etc.; general grippers, including two fingers to five fingers.

[0003] The "a quick-change gripper for a robot" disclosed in the patent publication number "CN216731858U", which relates to the technical field of robots, includes an arm. A rotating ring is movably sleeved at the left end of the arm, and a connecting block is fixedly connected to the left end of the arm. In the present utility model, the rotating ring is rotated. The rotating ring moves towards the arm until the rotating ring is completely separated from the thread ring, preventing the rotating ring from easily detaching from the connecting block, making the rotating ring and the connecting block have stable stability. The clamping block moves out of the inside of the fixed block and contracts towards the inside of the connecting block by the acting force when the spring shape is restored, pulling the claw to move away from the arm until the claw detaches, replacing the claw of the arm with a new one. By rotating the rotating ring and pulling the claw, it can be disassembled and replaced, making the robot have the characteristics of being easy to operate and disassemble, and improving the convenience when the claw is disassembled.

[0004] In view of the above related problems, the existing grippers adopt a spring clamping method. During actual use, since the robotic arm needs to move frequently, the spring is prone to shaking, resulting in unstable use of the gripper, and there is no good auxiliary maintenance function. During the maintenance process, it is difficult for lubricating oil to enter the inside of the gripper, which will affect the use effect.

[0005] Therefore, the present utility model provides a robot quick-change gripper to solve the above problems. Summary of the Utility Model

The inner side wall of the installation box 2 is connected with a round rod 35 through a bearing. One end of the round rod 35 is fixedly connected with a bevel gear two 36. The bevel gear two 36 is meshed and connected with the bevel gear one 32. A cross slot 37 is opened at one end of the round rod 35. The quick-change component 3 further includes a slide slot 38 and a slide block 39. The slide slot 38 is opened on both sides of the installation box 2. The slide block 39 is fixedly installed on both sides of the moving plate one 33. The slide block 39 is slidably connected with the slide slot 38. First clamping slots 4 are respectively opened on both sides of the installation box 2. An installation frame 7 is arranged above the installation box 2. The installation box 2 and the installation frame 7 are clamped with each other. First round holes 8 and second clamping slots 10 are respectively opened on both sides of the installation frame 7.
