Abstract
A three dimensional trigger measuring head structure is provided, which solves technologic insufficience of difficult installation error adjustment and poor adjusting precision of the measuring head in the prior art on a machine tool main shaft. The employed technical scheme is that, a casing of the measuring head adopts end plane magnetic connection. Two positioning balls and an upper casing, an intermediate connector and a lower casing of an adjustable bolt supporting and positioning are respectively arranged with 120 DEG. Through adjusting a supporting position of the supporting bolt, the end plane contacting angle of the upper casing, the intermediate connector and the lower casing is changed, hence the aim of a center of a sphere of a spherical measurement contact terminal arranged coaxially with the machine tool main shaft is realized. The measuring head has the beneficial effects that, structure is simple, and adjustment is convenient. Through the adjustment of the center of the sphere of the spherical measurement contact terminal 5 in the X direction and the Y direction in the plane, installation errors of the measuring head on the machine tool main shaft can be eliminated. Adjustment accuracy can reach 0.001 mm.
