Description

Technical Field

[0001] This utility model relates to the field of gripping components, specifically a spreading gripping component. Background Technology

[0002] Robotic arms are a new type of device developed in the process of mechanized and automated production. In modern production, robotic arms are widely used in the handling of various items. Most existing robotic arms have complex structures, cumbersome control processes, and high costs. Currently, robotic arms lack the ability to grip fixed frames, thus requiring improvement. Utility Model Content

[0003] The purpose of this utility model is to provide an openable gripper to solve the problems mentioned in the background art, which has the advantage of gripping a fixed frame.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spreading gripper, comprising a fixed plate, a placement plate fixedly connected to the fixed plate, a lifting cylinder fixedly connected to the placement plate, a lifting plate connected to the lifting cylinder, a lifting frame fixedly connected to the lifting plate, a gripper for gripping a fixed frame fixedly connected to the lower end of the lifting frame, a fixed shaft passing through the placement plate, a first rotating wheel sleeved on the fixed shaft, a second rotating wheel connected to the first rotating wheel via a belt, a connecting shaft passing through the second rotating wheel, a rotating motor for driving the connecting shaft to rotate being provided at one end of the connecting shaft, and a vision sensor being provided at one end of the fixed shaft.

[0005] By adopting the above technical solution, during the grasping process, the lifting cylinder is activated to move the lifting plate, which in turn moves the lifting frame. After the lifting frame moves, the grasping component moves up and down. When the grasping component moves to the fixed frame, it grasps the fixed frame. Then, the rotating motor is activated to rotate the connecting shaft, which in turn rotates the second rotating wheel. The second rotating wheel drives the first rotating wheel to rotate via a belt, which in turn drives the fixed shaft to rotate. The rotation of the fixed shaft drives the vision sensor to rotate. The vision sensor rotates 360 degrees to determine whether the grasping component has completed the grasping operation.

[0006] As a further embodiment of this utility model: a limiting block is fixedly connected inside the placement plate, and the limiting block is slidably connected to the lifting frame.

[0007] By adopting the above technical solution, the limit block plays a stabilizing role during the movement of the lifting frame.

[0008] As a further embodiment of this utility model: the gripping component includes a connecting frame fixedly connected to the lifting frame, the connecting frame is fixedly connected to a bracket, the bracket is provided with a plurality of spreading cylinders, and the spreading cylinders are connected to spreading blocks.

[0009] By adopting the above technical solution, after the bracket is inside the fixed frame, the opening cylinder is activated to drive the opening block to move outward until it squeezes the inside of the fixed frame, thereby achieving the purpose of gripping the fixed frame.

[0010] As a further embodiment of this utility model: the bracket includes an L-shaped plate and a square plate. A dual-head motor is fixedly connected to the inner side of the L-shaped plate. The output shaft of the dual-head motor is threadedly connected to a threaded rod. The threaded rod passes through the L-shaped plate. The threaded rod is square in shape, and the L-shaped plate is provided with a square groove for the threaded rod to pass through.

[0011] By adopting the above technical solution, the dual-head motor drives the output shaft to rotate. The threaded rod is set to be square and is located in a square groove, so that the threaded rod cannot rotate. Therefore, the threaded rod will move along its own length direction. One end of the threaded rod moves to the inside of the pressing and fixing frame, increasing the strength of gripping the fixing frame.

[0012] As a further embodiment of this utility model: the end face of the threaded rod is integrally connected to two cylinders, each cylinder has a cavity, a spring is installed in the cavity, one end of the spring is fixedly connected to a pressing rod, the side of the pressing rod is integrally connected to a limiting shaft, the inner side of the cylinder is provided with a limiting groove communicating with the cavity, and the limiting shaft is located in the limiting groove.

[0013] By adopting the above technical solution, after one end of the threaded rod moves towards the inside of the fixed frame, the threaded rod will drive the cylinder to move, which in turn will drive the pressing rod to move. After the pressing rod is squeezed by the inside of the fixed frame, the pressing rod moves inward to compress the spring, which has deformation space and avoids deformation of the inside of the fixed frame. During this process, the movement of the pressing rod drives the movement of the limiting shaft. The limiting shaft is restricted by the limiting groove, thereby limiting the movement trajectory of the pressing rod and increasing the stability of the limiting rod when it moves.

[0014] Compared with the prior art, the beneficial effects of this utility model are: During the gripping process, the lifting cylinder is activated to move the lifting plate, which in turn moves the lifting frame. After the lifting frame moves, the gripping component moves up and down. When the gripping component moves to the fixed frame, it grips the fixed frame. Then, the rotating motor is activated to rotate the connecting shaft, which in turn rotates the second rotating wheel. The second rotating wheel rotates the first rotating wheel via a belt, which in turn rotates the fixed shaft. The rotation of the fixed shaft rotates the vision sensor, which rotates 360 degrees to determine whether the gripping component has completed the gripping operation. Attached Figure Description
