Abstract

The invention discloses a precise detection device and detection method of principal axis cone hole accuracy. The device comprises a computer and a signal processing conversion module connected with the computer, the signal processing conversion module is connected with a cone-shaped measure gauge provided with an ultraphonic phased array probe, the signal processing conversion module comprises a phased array instrument and an adapter, the phased array instrument is connected with the computer through a data line, a control signal output end of the phased array instrument is connected with the adapter, and a command dispatch port of the adapter is connected with the ultraphonic phased array probe on the cone-shaped measure gauge through a prolonged cable. The precise detection device and detection method of principal axis cone hole accuracy adopts ultrasonic wave as a lossless detection means; detects contact pressure of a contact face according to ultrasonic wave reflectivity under the condition of not influencing an original contact condition; obtains pressure distribution on the contact face according to a corresponding relation between the ultrasonic wave reflectivity and contact pressure, enables a pressure distribution result to reflect a nominal contact area, and accordingly achieves precise detection of the principal axis cone hole accuracy.

Description

technical field [0001] The invention belongs to the technical field of mechanical detection, and relates to a detection device and a detection method, in particular to an accurate detection device and a detection method for the precision of a spindle taper hole. Background technique [0002] The contact area between the spindle and the tool holder in the precision machine tool is a conical joint surface. For this joint surface, the distribution of contact pressure will affect the contact stiffness, which in turn will have an important impact on the dynamic characteristics of the machine tool, thus directly affecting the machining accuracy. Therefore, it is extremely necessary to ensure the manufacturing accuracy of the spindle taper hole. [0003] At present, in the standards related to machine tool manufacturing, there are technical requirements for using the coloring method for inspection. For example, "Metal Cutting Machine Tool Cone Surface Coloring Method Inspection an...
