IPC: B23Q15/00
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To provide an absolute position determining method for machine tools that makes for precise setting of the position of working tools in machine tools using two driving links. SOLUTION: On one plane of a workpiece as a measurement sample, a reference position (x1, y1), a first position (x2, y2), a second position (x3, y3) and a third position (x4, y4) are imprinted to stand on first to third straight lines 73 to 75 all parallel to one reference line 72 at respective intervals Δ1 to Δ3. With the tool shifted from an initial position (x0, y0) to the reference and first to third positions, the respective telescoping levels (e) to (h) and (p) to (s) of the first and second driving links are detected, From those telescoping levels (e) to (h) and (p) to (s) and intervals Δ1 to Δ3, initial lengths L and R and an interval H between supporting points 63 and 64 are computed.  For tool- positioning, the initial lengths L and R and interval H thus obtained are determinative of the telescoping levels (e) to (h) and (p) to (s) of the first and second driving links.

Abstract: PURPOSE:To eliminate the uneven compression force to a cathode-ray tube and to improve the explosion-proof reliability by putting in a spacer to a shrinkage-fitting band in the form in which two sides of the spacer contacting with the band or their extensions cross each other. CONSTITUTION:A trapezoid spacer 6 is inserted to a band 2 between it ends. By moving the spacer 6 in the directions of the arrows, the distance l between the ends of the band 2 is increased or decreased. By increasing or decreasing the distance between the ends of the band 2, the circumferential length of the band 2 is also increased or decreased. After regulating the circumferential length of the band 2, the band is welded through a plate to make a circular band. As a result, the circumferential length of the band 2 can be regulated as desired even though it exceeds a prescribed length in the manufacture of the band, only by moving the spacer 6. Consequently, the relation of the circumferential length of the cathode-ray tube and that of the band 2 can be regulated adequately, and the uneven compression force to the cathode-ray tube can be eliminated.
