AUTOMATIC JIG FOR MACHINING FLAT-TYPE TEST PIECE AND AUTOMATIC MACHINING SYSTEM FOR FLAT-TYPE TEST PIECE

摘要

PURPOSE:To perform mechanical machining of various kinds of flat-type test pieces automatically without human operators by pushing the side parts of a plurality of the test pieces mounted on a receiving plate to a vertical reference surface, clamping the test pieces in the vertical direction, and detecting the completions of various kinds of operations. CONSTITUTION:The sizes of jigs are narrowed into several kinds based on the lengths and the grasping-part widths of test pieces 1. The jigs are arranged on a table of an NC machine tool for respective stages. The test pieces 1 which are conveyed on a conveyer are supplied into respective jigs by a robot. The test pieces are machined in accordance with programs based on the data for the kinds. At this time, a spacer 33 which is smaller than the finished size of the width of the upper part is arranged between the test piece 1 and a receiv ing plate 29 for mounting the test piece. The test pieces are pushed with a pushing plate to a reference surface 13a and clamping is performed. Then, the height position of the test pieces 1 on the jig is measured with a touch sensor. Cutting is performed with a cutter, and deburring is performed with a deburring tool. Then, the position is changed, and the other parts are cut.
