High-precision drilling device for industrial robot arm joint machining

Abstract

The invention relates to a high-precision drilling device for industrial robot arm joint machining. The high-precision drilling device for industrial robot arm joint machining comprises a drilling device body, the drilling device body comprises a supporting table, a movable table is arranged on one side of the supporting table, the supporting table is tightly attached to the movable table, and a drill bit is arranged on the lower side of the movable table. A cooling device, a heating device and a valve device are arranged in the supporting table, the cooling device is connected with a pipeline at the upper end of the drill bit, the heating device is electrically connected with the drill bit, a communication device is arranged in the drill bit, and through the cooling device, the heating device and the valve device, the drill bit can be pushed out of a hole after being shrunk, and hole wall smoothness is guaranteed; or the hole wall is coated with a tin layer, the hole is prevented from rusting, the problem that the hole is too large and difficult to repair is solved, the communication device is used for controlling whether the drill bit discharges liquid tin or not, and the device has the advantages that the qualified hole wall cannot be damaged, and the too large drilling problem can be solved.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, in particular to a high-precision drilling device for industrial robot arm joint processing. Background technique [0002] Drilling holes in solid materials with a drill is called drilling. Most of the hole machining of various parts is done by fitters using drilling machines and drilling tools. When drilling on a drilling machine, in general, the drill bit should complete two movements at the same time; the main movement, that is, the rotational movement of the drill bit around the axis; the auxiliary movement, that is, the linear movement of the drill bit against the workpiece along the axis direction. [0003] The industrial robot arm joint requires high precision. When the drill bit is taken out, due to the vibration of the machine or the human hand, the drill bit is easy to scratch the hole wall, which affects the accuracy of the hole; if the drilled hole is too large, it is us...
