Background

The surface of the existing part water jacket is provided with 12 equally-divided holes and 6 semicircular holes, the equally-divided holes and the 6 semicircular holes are distributed on two dividing circles with different diameters, and a traditional scribing method is adopted in the scribing process. Firstly, the cross center line of the part is clamped and aligned by a square box, and a copper sheet is inlaid in the inner hole of the workpiece, namely, the operation of borrowing is performed. At 4 points of intersection of the cross center line and the inner hole of the workpiece, the clamping feet of the scriber are clamped on the surface of the inner hole, and the clamping feet and the borrowed 'cores' are in a same plane in theory. The radius of the inner hole is taken as the side length, a drawing needle on the other clamping angle is used for drawing an arc on the copper sheet, 4 arcs are tangent to the surface of the copper sheet, one tangent point is obtained, namely the circle center of each reference circle is obtained, 12 reference circles which are equal to the holes are drawn by taking the point as the circle center, the reference circles are intersected with the cross center line, the sample punch is used for lightly punching a sample punching hole at 4 intersection points, and the chord length with the central angle of the reference circle of 15 degrees is calculated according to the diameter size of the pattern. And (3) drawing an arc by taking the intersection point of the cross center line and the reference circle as the center of a circle and the chord length of 15 degrees as the radius, intersecting the reference circle to obtain an intersection point, and punching a sample hole. Taking the point as an origin, taking the chord length of a 30-degree central angle as a side length, and sequentially cutting off 12 equal parts on the periphery of the reference circle to obtain 12 intersection points.
