Abstract

The invention discloses a large curved surface grinding self-adaptive grinding device. The device comprises a curved surface self-adaptive moving mechanism and a force controlled grinding tool module. The device is characterized in that the curved surface self-adaptive moving mechanism comprises a top tray, a cylindrical slot, a supporting rod and a universal wheel, wherein the top tray is provided with a supporting rod assembly hole, a top end motor assembly hole and a cylindrical slot assembly hole; the cylindrical slot is fixed on the top tray by virtue of a bolt; one end of the supporting rod is in fit connection with the universe wheel by virtue of threads, and the other end of the supporting rod is connected to the supporting rod assembly hole in the top tray by virtue of a bolt; the force controlled grinding tool module comprises the top end motor, a coupler, a screw rod, a nut, a spring, a force sensor, a dip angle sensor, three fine rod parts, a top three-legged chuck, a bottom three-legged chuck, a fixed board, a working motor and a grinder; and the top end motor is connected to the top end motor assembly hole in the top tray by virtue of a bolt, so that the curved surface self-adaptive moving mechanism and the force controlled grinding tool module are connected.

Description

technical field [0001] The invention relates to the technical field of mechanical autonomous grinding, in particular to a large-scale curved surface grinding self-adaptive grinding device. Background technique [0002] In the traditional current surface grinding industry, it is generally done manually by skilled workers. Manual grinding is not only labor-intensive, time-consuming and labor-intensive, but also inefficient, and it is difficult to ensure the integrity and consistency of the workpiece shape and surface quality; at the same time, the noise, dust and short fibers on the job site also seriously affect the health of workers. [0003] In the prior art, most of the grinding tools are directly held by the robot for grinding. Although the surface quality of the workpiece is high, it is necessary to teach the trajectory of the robot according to the workpiece model and the grinding area before grinding. Since the positioning dimensions of workpieces are inconsistent, re...
