The invention belongs to the technical field of precision test, and relates to a laser measurement measuring head device for measuring a form and position error of any surface . The device comprises aspherical measuring head, a spring limiting plate, a spring, a guide shaft, a dense bead shaft sleeve, a bushing, a target mirror mounting base, a target mirror and a housing. The device is capable of proportionally converting the displacement of a point testing position into the displacement of the target mirror to achieve precise measurement of a curved surface and a non-reflective surface. Byadjusting the size of the component, the measurement of infinitesimal displacement can be realized, and the measurement of large displacement can be further realized. The displacement transmission components of the device are rigidly connected, and the displacement transmission precision is high; an axis of the device and a normal line of the to-be-tested surface are located on the same straight line, and no measurement abbe error exists. The device has the advantages of simple structure, no measurement abbe error, wide application range and high displacement transmission precision, and has good market application prospects and promotion values.
