Intelligent drilling machine based on six-degree-of-freedom parallel robot

Abstract

The invention discloses an intelligent drilling machine based on a six-degree-of-freedom parallel robot, belongs to the technical field of intelligent drilling machines and aims to solve the problems of poor manual positioning accuracy, low manual positioning efficiency and poor drilling accuracy in the prior art. The intelligent drilling machine comprises a base, a stand column, a rocker arm, a spindle box, a drill bit, displacement sensors, the six-degree-of-freedom parallel robot and a controller, wherein the lower end of the stand column is fixedly connected with the base; one end of the rocker arm is arranged on the stand column in a sleeving mode and the rocker arm can move up and down relative to the stand column; the spindle box moves leftwards and rightwards relative to the rocker arm; the drill bit extends out of the lower end of the spindle box, is connected with a spindle in the spindle box and is capable of performing rotational motion and feeding motion; the displacement sensors are fixed to the lower end of the spindle box, the outer cylindrical surface of the end, extending out of the spindle box and connected with the drill bit, of the spindle is fit with the displacement sensors, and the position information of a to-be-machined surface of a workpiece is acquired in real time through the displacement sensors; the six-degree-of-freedom parallel robot is fixed to the base and corresponds to the drill bit in position, and the workpiece is arranged on a movable platform of the six-degree-of-freedom parallel robot; and the controller is disposed in the spindle box and electrically connected with the six-degree-of-freedom parallel robot and the displacement sensors.

Description

technical field [0001] The invention belongs to the technical field of intelligent drilling machines, and in particular relates to an intelligent drilling machine based on a six-degree-of-freedom parallel robot. Background technique [0002] Drilling machine refers to a machine tool that uses a drill bit to process holes on a workpiece. Among them, the radial drilling machine is widely used due to its simple structure. Usually, when processing a workpiece, in addition to ensuring the position accuracy of the hole, it is also necessary to ensure that the processing surface and the drill bit are always in a vertical state. For a simple workpiece with only one processing surface, it only needs to be clamped once to complete the processing. However, for complex workpieces, it may be necessary to drill holes on many non-parallel surfaces, and it is also possible to drill holes on curved surfaces. At this time, multiple clamping is required to ensure that the drill bit is perpend...
