Multi-degree-of-freedom reverse drilling robot

Abstract

The invention discloses a multi-degree-of-freedom reverse drilling robot. The robot comprises a Z-axis module, an X-axis module, a rotating module and a base, wherein a drilling tool is installed on the Z-axis module, one end of the drilling tool is fixed to a first guide column through a supporting block and a clamping base, and in the Z-axis module, one end of a first trapezoidal lead screw pairis connected with a push rod through a nut; a hollow shaft push rod is arranged outside the first trapezoidal lead screw pair, and a bearing seat is installed at the lower end of the first trapezoidal lead screw pair; the Z-axis module is installed on the X-axis module, and the X-axis module drives the second trapezoidal lead screw pair for transmission by adopting a servo motor and is connectedwith the Z-axis module through a nut; the rotating module drives the speed reducer to match with a gear set through the servo motor to provide rotation in a horizontal direction and rotation in a vertical direction, the X module is connected with a horizontal steering gear of the rotating module, and the rotating module is installed on the base and can vertically rotate along a vertical rotating shaft of the base. The degrees of freedom are all controlled by the servo motor to achieve accurate positioning.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a multi-degree-of-freedom reverse hole-making robot. Background technique [0002] At present, manual drilling is mostly used in the reverse drilling of the arc top, and the manual drilling speed is slow and the strength is high, which is easy to cause fatigue. Automated drilling can be fast and can work continuously for a long time, but simple improvements to existing equipment cannot satisfy the reverse drilling of the arc top, such as the robot arm cannot withstand the impact of drilling force and remain relatively rigid, the three-coordinate has no axis of rotation and can only drill holes on flat tops. Also there is no robot equipment developed for arc roof or inclined roof drilling on the market. Therefore the market is badly in need of developing a novel multi-degree-of-freedom reverse hole-making robot to help people solve the problems mentioned above. Cont...
