Numerical control full-automatic machine tool special for cams

Abstract

The invention belongs to the technical field of numerical control machine tools and relates to a numerical control full-automatic machine tool special for cams. A horizontal guide rail arranged on the front side of a base is provided with a workpiece fixture capable of moving along the horizontal guide rail; a longitudinal guide rail arranged on the back side of the base is provided with a headstock; a vertical guide rail arranged on the front side of the headstock is provided with a head seat; a cantilever is fixedly arranged on the lower side of a vertical shaft which is vertically arranged on the front side of the head seat; a horizontal guide rail arranged on the cantilever is provided with a motor; an output shaft of the motor is provided with a cutter; all kinematic pairs are driven to move by motors; and a controller controls all motors to sequentially act. The numerical control full-automatic machine tool special for cams has the advantages that a numerical control technology and three-dimensional machining are adopted, the machined cams have smooth and continuous moving tracks and arcs, the yield is high, the production efficiency is high, the production cost is low, and the machine tool is suitable for machining cams with various complex surfaces and tracks.

Description

technical field [0001] The invention belongs to the technical field of numerically controlled machine tools, in particular to a numerically controlled full-automatic cam special processing machine tool. Background technique [0002] At present, the machine tools used to process cams can only process cams such as simple curved surfaces and curves, while the processing of spiral cams with complex curved surfaces and complex trajectory control is realized by segmented processing. The disadvantage is that : First, the continuity of the segmented cam surface is not good. Using this cam to control the running track, the running track is intermittent, unstable and discontinuous, and the accuracy of the control is not high, resulting in the quality of the processed product. It is difficult to guarantee, the qualified rate is low, and high-precision control cannot be realized; the second is that the processing efficiency is low and the production cost is high.
