Embodiment Construction

[0018] An embodiment of the present invention will be described below with reference to the drawings.

[0019] figure 1 It is a schematic diagram of one embodiment of the present invention. In this embodiment, a machined workpiece 5 such as a machine part is fixed at a predetermined position on a table (not shown), and a machining tool 4 is attached to the front end of the arm of the robot body 1 via a force sensor 3 . The finishing device of the present invention uses the machining tool 4 to remove the flash 6 on the workpiece 5 to be machined. In addition, in figure 1 In , mark 2 is the control device of the robot, and the robot main body 1 is controlled and operated by the control device 2 . In addition, the cutting edge of the machining tool 4 is in a rotating form, and the driving control of the machining tool 4 is also performed by the control device 2 .

[0020] The force sensor 3 detects the pressing force of the machining tool 4 during machining and when profiling...

Abstract

The present invention provides a finishing machine characterized in that useless burr removing actions can be reduced and, further, that the overcutting of a workpiece can be prevented. A surface of a workpiece, from which the burr is removed, is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape. This positional data is corrected by an error caused by a bend of a robot. The thus obtained positional data is compared with the target shape of the surface, from which the burr is removed, obtained from CAD data. A shift of the surface shape in the normal line direction is found. The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position, the shift end position and the shift size. A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed. As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed.

Description

technical field [0001] The present invention relates to a finishing machine for removing burrs on the surface of machined workpieces such as machine parts by using a robot. Background technique [0002] As a method of removing burrs from workpieces such as mechanical products, there is a known method of automatically removing burrs using a robot. With the workpiece to be machined fixed at a predetermined position, the machining tool for deburring is mounted on the robot. Then, using a mechanical floating mechanism by spring or air pressure or using software pressure control, the machining tool is pressed against the cut-off flash surface of the workpiece with a prescribed pressure and the cut-off flash surface is moved to remove the flash. . In addition, in the state where the machining tool for deburring is fixed at a predetermined position, the workpiece is held by a robot, and the workpiece is pressed against the machining tool for deburring with a predetermined pressur...
