Description

Technical Field

[0001] The utility model relates to a mechanical arm sliding structure, belonging to the field of mechanical arm equipment. Background Art

[0002] The sliding structure of a robotic arm means that a certain component on the robotic arm can slide within a plane to increase the working range and flexibility of the robotic arm. Generally speaking, the sliding structure of a robotic arm can be divided into two types: plane sliding structure and three-dimensional sliding structure.

[0003] In the prior art, planar sliding structures are generally used for robotic arms with a smaller working range, and their sliding parts can slide within a plane of the robotic arm, thereby increasing the working range and flexibility of the robotic arm. For example, the arms in some assembly robotic arms can slide within a horizontal plane to better operate the workpiece. However, the planar sliding structure in the robotic arm usually requires load sliding, and the slider is affected by the gravity of the load and is prone to sliding outside the operating range, thereby reducing the working accuracy of the robotic arm and reducing the working stability of the robotic arm.

[0004] In summary, the utility model provides a mechanical arm sliding structure to solve the above problems. Utility Model Content

[0007] Furthermore, the rack is meshed with the driving wheel, and one side of the mechanical main arm is open.

[0008] Furthermore, the electromagnetic shaft is fixedly connected to the driving wheel, and bolts penetrate all around the front side of the connecting seat.

[0009] Furthermore, the electric clamping assembly includes a mounting seat, which is fixedly connected to the surface of the sliding main block and is located outside the mechanical main arm. A movable groove is opened inside the mounting seat, and a bending clamping plate is slidably connected inside the movable groove. One end of the bending clamping plate extends to the top of the mounting seat, and a fixed block is fixedly connected to one side of the top of the mounting seat. An electric push rod is fixedly connected to one side of the fixed block, and an output end of the electric push rod extends to one side of the bending clamping plate.

[0010] Furthermore, the top of the movable groove is connected to the upper part of the mounting seat, and one side of the movable groove is connected to the outside of the mounting seat.

[0011] Furthermore, the cross section of the mounting seat is a right-angled rectangular shape, and the two electric clamping components are installed in a mirror-symmetrical structure.

[0012] Furthermore, one side of the bending clamping plate is fixedly connected to the output end of the electric push rod, and one end of the bending clamping plate is adapted to the clamping slot.

[0013] Beneficial effects of the utility model:

The sliding main block can be locked through the bending clamp and the clamping slot, so that after the electromagnetic shaft is closed, the sliding main block will not rotate due to its own gravity, thereby effectively improving the working stability of the sliding structure of the robotic arm.

[0015] The electric clamping assembly can be used to match the sliding distance of the sliding main block and select clamping slots at different positions for clamping, thereby effectively increasing the sliding locking range of the mechanical arm sliding structure and expanding the operating range.
