Embodiment Construction

[0042] The full-parameter measurement system with the inner hole of the bearing ring as a tapered hole is as follows: figure 1 , 2 , 3, the mechanical part consists of a measuring platform 1, a measuring fulcrum 2, a radial auxiliary fulcrum 6, and two measuring heads 4, 5 with displacement sensors. When measuring, the small end surface of the inner hole of the bearing ring 3 is in close contact with the measuring platform 1, and the three points of the measuring fulcrum 2, the auxiliary fulcrum 6 and the probe 5 are distributed at 90° in the same radial plane at the small end of the inner hole, and the fulcrum 2 and the The probe 5 should be on the same straight line along the diameter, and the three points of the measuring point and the fulcrum should deviate from the chamfer at the small end of the inner hole; the other probe 4 should be placed directly above the measuring fulcrum 2, and the two points should be located on the same generatrix on the surface of the inner hol...

Abstract

The invention relates to an all-parameter measuring system with a bearing ring inner hole as a conical bore and a measuring method for the all-parameter measuring system. The system comprises a measuring fulcrum, an auxiliary fulcrum and two measuring heads, wherein the measuring fulcrum, the auxiliary fulcrum and the measuring heads are arranged on a measuring platform; the measuring heads are provided with displacement sensors; output signals of the two sensor measuring heads are transmitted into a signal amplifying module, a signal processing module and a display module which are connected in sequence; and the signal processing module is further connected with an input device in an input manner. The measuring device is simple to adjust, and belongs to common bearing instruments; measurement requirements on a volume production field can be met; measurement cost is greatly reduced; measurement on whole technical parameters of a conical bore can be accomplished at a single working position; working efficiency is greatly improved; a simple circuit control part is adopted to accomplish relatively complex calculation processes; artificial measurement errors caused by operating personnel is avoided; and meanwhile, labor intensity of the operating personnel is lightened; storage and process to measurement data can also be realized through the circuit control part, thereby being convenient for a quality engineer to monitor and control quality of a working procedure product in real time.

Description

technical field [0001] The invention belongs to the technical field of conical inner hole detection, and relates to a full-parameter measurement system and method in which the inner hole of a bearing ring is a conical hole. Background technique [0002] The main control parameters of the tapered hole are the taper of the tapered hole, the diameter of the small end of the tapered hole, and the perpendicularity of the reference end to the centerline of the inner hole. The taper of the taper hole is mainly used to control the angle parameters of the cone on the surface of the inner hole of the cone. Its machining accuracy directly affects the reliability and self-centering of the bearing when it is installed on the shaft, so it is often strictly controlled in production. When the diameter of the end face of the taper hole is known, the taper of the taper hole can be obtained by calculation. At present, the commonly used measurement methods for measuring the conical inner hole ...
