[0002] Xiaoblin lathes are ultra-high-precision equipment, used to process products with complex structures, high precision requirements, and high one-time success rates. Therefore, lathes must be kept in good condition at all times. At present, there is no corresponding Xiaoblin machine tool imported from my country We cannot complete the normal inspection work to ensure the high-precision operation of the machine tool, and foreign countries have blocked the standard. We cannot obtain either the material or the accuracy index. In order to ensure the normal use of the Xiaoblin lathe, we must independently Developed inspection tools for Shoblin lathes

Embodiment Construction
[0014] Taking the inspection mandrel for processing 180 Shoblin lathe as an example, the precision standard of Shoblin lathe is that the axial movement of the spindle is ≤0.005mm and the radial runout is ≤0.005mm.
[0015] Such as figure 1 As shown, the quenched and ice-cooled No. 45 steel rod is processed by a precision lathe into a small cylindrical tapered handle 1 with a diameter of 24.99+0.01 mm and a length of 76.52±0.01mm and a diameter of 33.85+0.01mm and a length of 200± 0.1mm large cylinder reference axis 2, a connecting body with a 165±1° chamfer 6 at the joint of the two cylinders, a 45° central taper hole 3 at both ends, and an outer cylindrical surface at the end of the taper shank 1 that is in line with the Xiao The Bollinger lathe fixture has a keyway 4 with the same fixed key size and an external thread 5 with the same thread size as the threaded rod in the fixture, and then the reference axis 2 is finished with a mirror lathe, and a small machining allowance ...

Abstract
The invention relates to a mandrel for detecting a Shaw Brin lathe and a machining method. The mandrel is formed by a taper shank, a basic shaft and a chamfer on the joint between two cylinders, wherein the basic shaft is a cylinder which is 200mm long, accuracy requirements of the basic shaft for straightness accuracy and coaxiality are respectively 1 / 3-1 / 5 of accuracy requirements of a main shaft of the Shaw Brin lathe for axial drifting and radial jumping, the two ends of the basic shaft are provided with ground central conical holes, the shape and dimension of the conical handle and the shape and dimension of the chamfer are the same as those of an inner hole of the main shaft of the Shaw Brin lathe, and the conical handle and the chamfer are in clearance fit. The mandrel has the technical advantages that a national blockade on new techniques is broken through, daily inspection operation for the Shaw Brin lathe under the situation that detecting tools do not exist is achieved, and high-precision operation of the lathe at any time is guaranteed.
