Problems solved by technology

[0003] The purpose of the present invention is to overcome the defect that the existing technology cannot be used to measure curved surfaces larger than itself when measuring special-shaped parts, the measurement speed is slow, and it is easy to cause the surface tissue of the measured curved surface to be squeezed and scratched. The non-contact special-shaped surface detection device can ensure that the whole device is horizontal before measurement, and the horizontal and vertical scanning angles are controlled accurately. It is non-contact measurement and will not cause the surface tissue of the workpiece to be squeezed or scratched. The processing technology of special-shaped parts The adjustment is instructive

Abstract

The invention discloses a non-contact special-shaped surface detection device, which belongs to the technical field of parts detection device design, including a foot, a base, a horizontal scanning stepping motor, a worm, a worm wheel, a longitudinal scanning stepping motor, a pinion and a large gear 1. Laser length measuring instrument. There are three legs connected to the lower end of the base. The worm is fixedly connected to the motor shaft of the horizontal scanning motor. Fixedly connected with the big gear, the non-contact special-shaped surface detection device designed by the present invention can ensure that the whole device is horizontal before measurement, and the horizontal and longitudinal scanning angles are controlled accurately. It is non-contact measurement and will not cause surface tissue damage Being squeezed and scratched has guiding significance for the adjustment of the processing technology of special-shaped parts.

Description

technical field [0001] The invention relates to the technical field of part detection device design, in particular to a non-contact special-shaped surface detection device. Background technique [0002] With the development of the machinery industry, the shapes of mechanical parts vary widely. In the shaft-hole fitting parts, the advantages of special-shaped cross-sections are very obvious. Therefore, more and more machine tools use the special-shaped shaft-hole fit method when transmitting torque, but The detection of special-shaped shafts or special-shaped holes is very troublesome. The three-coordinate measuring machine is a traditional measuring device for the detection of special-shaped surfaces. It mainly uses a probe with a spherical end to touch the workpiece with a certain measuring force to measure the three coordinate directions. Displacement, that is, the three-dimensional coordinate value of the probe in the machine tool coordinate system. This device cannot be ...
