Non-circular curved surface part self-adaption polishing machine

Abstract

The invention discloses a non-circular curved surface part self-adaption polishing machine. The non-circular curved surface part self-adaption polishing machine mainly comprises a stepping motor, a lead screw, a rectangular sliding table, a workpiece driving part, a main shaft, a vertical bearing block, a strain gage, a control system single chip microcomputer, a table type polishing machine and the like; the strain gage is fixed to the side wall of the vertical bearing block, a workpiece is driven by a direct current motor to rotate along with the main shaft, the grinding force of a grinding wheel on the workpiece is transmitted to the vertical bearing block to enable the vertical bearing block to generate strain, a strain signal is transmitted to the control system single chip microcomputer, and the rotating direction and feed of the stepping motor are adjusted by detecting the exceeding range of the strain to the preset scope; and through the feedback effect of force, the grinding force keeps constant. By means of the non-circular curved surface part self-adaption polishing machine, the surface grinding quality of a non-circular curved surface part can be effectively improved, harms of polishing noise and dust to workers in the manual polishing process can be effectively overcome, the beneficial effects of being simple in structure, convenient to operate, simple in workpiece clamping, low in constructing cost, high in product serial degree and the like are achieved, and the non-circular curved surface part self-adaption polishing machine is suitable for polishing machining of the non-circular curved surface part.

Description

technical field [0001] The invention relates to a grinding machine, in particular to an adaptive grinding machine for non-circular curved surface parts Background technique [0002] The processing and polishing of non-circular surface parts need to be completed by corresponding numerical control equipment. Due to the inconsistency of the curvature of each point on the contour of non-circular surface parts, the grinding process is complicated, and it is difficult to guarantee the machining accuracy with traditional CNC machine tools. At present, most of the polishing equipment adopts the abrasive belt grinding technology, but the abrasive belt grinding technology is usually suitable for workpieces with large size and complex structure. It is more economical to use the manipulator clamping method for grinding, and it depends on the operation of workers. The degree of proficiency subjectively feels the size of the grinding force to control the grinding allowance. This kind of g...
