Problems solved by technology

[0004] When the technician reads the value of the radial runout of the spindle of the CNC machine tool from the dial indicator or dial indicator, it is difficult to read from the dial indicator or the dial indicator when the spindle radial runout has only slight changes The value of the radial runout of the spindle changes. In this way, the error of the recorded value of the radial runout of the spindle increases, so that the numerical error of the radial runout of the spindle of the CNC machine tool determined according to the recorded data is relatively large, which affects the evaluation of the performance of the CNC machine tool

Embodiment 1

[0059] see Figure 1A , an embodiment of the present invention provides a device for measuring the radial runout of a spindle. The device includes: a measuring element 1, a transmission element 2 and a signal conversion element 3;

[0060] The measuring element 1 is respectively connected with the spindle detection rod S1 and the transmission element 2, detects the radial displacement of the spindle, and transmits the radial displacement signal of the spindle to the transmission element 2 to drive the transmission element 2;

[0061] The signal conversion element 3 is connected with the transmission element 2, converts the radial displacement signal of the main shaft transmitted by the transmission element, and outputs the radial runout signal of the main shaft in the form of an electric signal.

[0062] The above-mentioned spindle detection rod S1 is connected to the spindle of the CNC machine tool, and before the radial runout of the spindle is measured, the spindle detectio...

Abstract

The invention provides a device for measuring radial run-out of a main shaft. The device comprises a measuring element, a driving element and a signal conversion element. The measuring element is connected with a main shaft detection rod and the driving element, so that the radial displacement of the main shaft is detected and the main shaft radial displacement signal is transmitted to the driving element to drive the driving element to drive; and the signal conversion element is connected with the driving element and is used for converting the main shaft radial displacement signal transmitted by the driving element, and outputting a main shaft radial run-out signal in the form of an electrical signal. The device realizes automatic real-time acquisition of main shaft radial run-out displacement, automatic reading of the main shaft radial displacement change, and automatic conversion from the main shaft radial displacement change in the mechanical form into the main shaft radial run-out signal in the form of the electrical signal, so that the high-precision main shaft radial run-out signal in the form of the electrical signal is output, and more convenience can be provided for the follow-up processing of the main shaft radial run-out signal.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools and measuring devices, in particular to a device for measuring the radial runout of a spindle. Background technique [0002] At present, when measuring the processing quality and efficiency of CNC machine tools for parts, the radial runout of the spindle of the CNC machine tool can be measured, and the processing quality and efficiency of the parts for the CNC machine tool can be explained according to the data of the radial runout of the spindle. [0003] At present, the radial runout of the CNC machine tool spindle is measured by a lever dial indicator or a dial indicator. The dial indicator or dial indicator is composed of a meter head, a transmission mechanism and a lever. When using a dial indicator or a dial indicator to measure the radial runout of the spindle of a CNC machine tool, put the lever close to the detection rod gently, and use the lever-gear transmission ...
