The bolts are prone to slippage after long-term use, making it impossible to disassemble. In the process of disassembling multiple bolts, the more bolts are removed, the more unstable the gripper installation is. If it falls, it is easy to cause damage. However, the grippers used in the existing robot clamps do not have a component for convenient replacement.
[0004] The present utility model is implemented as follows: the gripper replacement structure of the robot clamp includes a manipulator component and a device shell, the bottom of the manipulator component is fixedly connected to the top of the device shell, the surface of the device shell is movably connected to the mounting shell, the bottom of the mounting shell is fixedly connected to the gripper, and the inner cavity of the device shell is provided with a limiting device.
[0005] As a preferred embodiment of the present invention, the limiting device includes two limiting blocks, and springs are fixedly connected to the opposite sides of the two limiting blocks. A movable hole is opened on the surface of the limiting block, and the inner cavity of the device shell is fixedly connected with a movable rod used in conjunction with the movable hole. The surface of the movable rod is movably connected to the inner cavity of the movable hole. By setting the limiting device, when the mounting shell moves to the surface of the device shell and the clamp moves to the bottom of the manipulator component, the limiting device has a limiting effect on the position of the mounting shell and the clamp.

The restoring force generated by the spring restoring its shape will drive the limit blocks to be stuck in the inner cavity of the limit groove. The limit device has a limiting effect on the position of the mounting shell and the clamping claw. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

A movable hole 503 is opened on the surface of the limiting block 501. The inner cavity of the device shell 2 is fixedly connected to a movable rod 504 used in conjunction with the movable hole 503, and the surface of the movable rod 504 is movably connected to the inner cavity of the movable hole 503.
[0024] Adopting the above solution: by setting the limiting device 5, when the mounting shell 3 moves to the surface of the device shell 2 and the clamping jaw 4 moves to the bottom of the manipulator component 1, the limiting device 5 has a limiting effect on the position of the mounting shell 3 and the clamping jaw 4.
[0025] refer to Figure 4 The surface of the moving rod 504 is sleeved with two moving extrusion blocks 6 used in conjunction with the limiting block 501 , and the surface of the moving extrusion block 6 contacts the surface of the limiting block 501 .
[0026] The above solution is adopted: by setting the movable extrusion block 6, the extrusion force generated on the movable extrusion block 6 when the extrusion frame 8 moves can drive the two movable extrusion blocks 6 to move, and when the movable extrusion block 6 moves, it can drive the limit block 501 to move.
[0027] refer to Figure 3 The inner cavity of the device shell 2 is movably connected to two handle frames 7, and the side of the handle frame 7 away from the movable extrusion block 6 passes through the device shell 2 and extends to the outside of the inner cavity of the device shell 2.
[0028] The above solution is adopted: by providing the handle frame 7 , when the handle frame 7 moves, the squeezing frame 8 can be driven to move along the surface of the movable squeezing block 6 .
[0029] refer to Figure 3 The bottom of the handle frame 7 is fixedly connected to an extrusion frame 8 used in conjunction with the mobile extrusion block 6, and the inner cavity of the extrusion frame 8 is in contact with the surface of the mobile extrusion block 6.
[0030] The above solution is adopted: by providing the extrusion frame 8 , when the extrusion frame 8 moves, an extrusion force can be generated on the movable extrusion block 6 .
[0031] refer to Figure 5The left and right sides of the inner cavity of the mounting shell 3 are both provided with limiting grooves 9 for use with the limiting block 501 , and the surface of the limiting block 501 contacts the inner cavity of the limiting groove 9 .
[0032] The above solution is adopted: by setting a limit groove 9, when the mounting shell 3 moves to the surface of the device shell 2, the handle frame 7 is released, and the restoring force generated by the spring 502 restoring its shape will drive the limit block 501 to be stuck into the inner cavity of the limit groove 9.

The coordinated use of the positioning rod 11 and the positioning groove 10 has a limiting effect on the moving position of the mounting shell 3.
[0035] The working principle of this utility model:
[0036] During use, when the gripper 4 used in the robot clamp needs to be replaced conveniently, the operator first removes the gripper 4 that needs to be replaced, and then pulls the handle frame 7 to the opposite side of the two handle frames 7. When the handle frame 7 moves, it will drive the squeezing frame 8 to move along the surface of the moving squeezing block 6. The squeezing frame 8 will generate an squeezing force on the moving squeezing block 6. The two moving squeezing blocks 6 subjected to the squeezing force will move along the surface of the moving rod 504 toward the side close to each other. When the moving squeezing block 6 moves, it will drive the two limit blocks 501 along the moving rod 504. The surface of the movable rod 504 moves toward the side that is closer to each other. When the limit block 501 moves, the force generated causes the spring 502 to elastically deform. When the limit block 501 is completely moved to the inner cavity of the device shell 2, the mounting shell 3 is moved to the surface of the device shell 2 and the handle frame 7 is released. The restoring force generated by the spring 502 recovering its shape will drive the limit block 501 to be stuck in the inner cavity of the limit groove 9. The coordinated use of the limit block 501 and the limit groove 9 has a limiting effect on the position of the mounting shell 3 and the clamp 4. At this time, the clamp 4 used by the robot clamp is easily replaced.
[0037] To sum up: the gripper replacement structure of the robot clamp solves the problem that the gripper of the existing robot clamp is a device for fixing or moving objects, which is usually installed on the robot's mechanical arm. The type of gripper needs to be replaced according to different usage scenarios. When replacing, it is usually necessary to use professional auxiliary tools to disassemble multiple bolts. The bolts are prone to slippage after long-term use, resulting in the phenomenon that they cannot be disassembled. In the process of disassembling multiple bolts, the more bolts are removed, the more unstable the gripper installation is. If it falls, it is easy to cause damage. However, the gripper used in the existing robot clamp does not have a component for convenient replacement.
