Abstract

The invention provides an intersection point expose two serial-connected adjacent crossing rotary axes coplane degree detection device. The device comprises a detection component and a displacement sensor, wherein the detection component comprises a connecting piece which is arranged on the lower surface of a rear rotary shaft component rotator of a detected object, a three-dimensional movement fine tuning mechanism, a bent plate and a standard sphere; and the displacement sensor comprises an X-directional displacement sensor, a Z-directional displacement sensor and a Y-directional displacement sensor, the three displacement sensors are arranged along normal directions of X, Z and Y coordinate directions of the standard sphere respectively, and probes of the three displacement sensors arealigned to the body of the standard sphere along the normal line of the spherical surface. The invention also discloses an intersection point expose two serial-connected adjacent crossing rotary axescoplane degree detection method, which realizes coplane degree detection of two serial-connected adjacent crossing rotary axes of a detected component with an included angle theta of an arbitrary value by utilizing the detection device, and the accuracy of the detection result is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of geometric accuracy detection of machines with rotary motion, and relates to a detection device for the coplanarity of the axes of two series adjacent intersecting rotary shafts with exposed intersection points. Face detection method. Background technique [0002] There are many cases where there are two series, adjacent and intersecting rotary motion axes in the machine, such as the series adjacent intersecting A axis and C axis, A axis and B axis, B axis and The motorized spindle, A-axis and motorized spindle, and the series-adjacent and intersecting rotary joints in the robot, etc. all belong to two series, adjacent and intersecting rotary motion axes. The axis coplanarity accuracy of two rotary motion axes that are adjacent to each other in series has an important impact on the geometric accuracy of the machine as a whole. When the axis intersections of two serially adjacent intersecting rotary motio...
