Description

Technical Field

[0001] The utility model relates to a rotary support base device of an industrial robot, belonging to the field of industrial robots. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities. Industrial robots are all provided with a base at the bottom, and this base can be rotated so that the robot can work at various angles. The base includes a connection plate for connecting the robot, and a servo motor is installed at the bottom of the connection plate, wherein the servo motor is installed in the support cylinder. In order to reduce the wear between the connection plate and the support cylinder, a support wheel is often installed between the connection plate and the support cylinder. The connection plate is driven by the servo motor to make the support wheel roll along the upper surface of the support cylinder. After the support wheel is in contact with the support cylinder for a long time, the contact parts of the support wheel, the support cylinder and the support wheel will be worn and deformed. The distance between the connection plate and the support cylinder is small, so it is necessary to disassemble more parts such as the connection plate to replace the support wheel and the support cylinder, which is time-consuming and labor-intensive. Therefore, it is necessary to design a rotating support base mechanism for industrial robots that is convenient for replacing wear parts. Utility Model Content

[0005] Furthermore, a ring is fixedly connected to the lower surface of the connecting plate, and the ring is in sliding contact with the inner wall of the supporting tube.

[0006] Furthermore, the upper surface of the connecting plate is provided with a plurality of circular holes for inserting screws at equal intervals in a circular shape, and the annular side surface of the connecting plate is provided with a plurality of slots at equal intervals in a circular shape.

[0010] Beneficial effects of the utility model:

[0011] 1. The movable cylinder is sleeved on the supporting cylinder, and the movable cylinder and the base are connected by an electric push rod. After the electric push rod is controlled to extend, the two semicircular pads installed on the upper surface of the movable cylinder are in contact with the supporting wheels on the connecting disk. Under the action of the semicircular pads, the supporting wheels are prevented from directly contacting the movable cylinder. When the semicircular pads are worn, the semicircular pads can be replaced without replacing the movable cylinder. When the worn supporting wheels and semicircular pads need to be replaced, the electric push rod is controlled to retract, and the electric push rod controls the movable cylinder to move downward, so that the spacing between the semicircular pads and the connecting disk is expanded, so as to expand the space for replacing the supporting wheels and semicircular pads. There is no need to disassemble the connecting disk and other components for replacement. The semicircular pads and the movable cylinder work together, and there is no need to make the supporting cylinder contact with the connecting disk.

[0012] 2. Insert the plug plate with screw holes matching the screws into the slots on the connection plate to realize the assembly of the plug plate and the connection plate. There is no need to directly process screw holes matching the screws on the connection plate. When the screw holes are damaged due to wrong threads during the process of connecting the robot and the connection plate, it is only necessary to replace the plug plate without replacing the entire connection plate.
