Embodiment

[0025] Such as figure 1 As shown, the non-contact measuring device for the inner and outer diameters of large-diameter ring parts involved in this embodiment consists of a base (1), a rotating table (2), an elevating table (3), an inner and outer diameter adjustment frame (5), and an inner diameter probe (6) and outer diameter probe (7) form. The lifting table (3) drives the inner and outer diameter adjustment frame (5) to move up and down, and the inner diameter probe (6) and the outer diameter probe (7) are fixed on the inner and outer diameter adjustment frame (5).

[0026] The workpiece to be measured is the ring part (4) to be measured.

[0027] Such as figure 2 As shown, the turntable (2) is composed of a motor (8), a worm drive (9), a turntable (10), an encoder (11) and a fixture (12). The encoder (11) is coaxially connected with the rotating table (10) for monitoring its rotation angle. The encoder (11) selected in this embodiment generates 20000 pulses per rotatio...

Abstract

The invention, which belongs to the technical field of industrial measurement, discloses a non-contact measurement apparatus of inner and outer diameters of a large-diameter circular ring type component. According to the apparatus, a rotation platform (2) drives to-be-measured circular ring type components to make rotation; a non-contact laser displacement sensor is used for measuring the inner diameters and the outer diameters of the to-be-measured circular ring type components (4); and measurement of the to-be-measured circular ring type components (4) with different dimensions can be realized based on fine tuning of a lifting platform (3) and an inner-outer diameter adjusting rack (5). With the apparatus, automatic non-contact measurement of the inner diameter, outer diameter, thickness, and ovality of a circular ring type component can be realized; the measurement error is small; the operation is simple and convenient; the measurement speed is fast; and the work efficiency is high. The provided measurement apparatus is suitable for bath detection occasions of large-diameter circular ring type component production and processing enterprises.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement, and in particular relates to a non-contact measuring device for inner and outer diameters of large-diameter circular ring parts, which is used for measuring the inner diameter, outer diameter, thickness and ellipticity of large-diameter circular ring parts. Background technique [0002] There are many kinds of circular ring parts, such as rollers, rotors, rings, pistons, roller sleeves, bearings, etc., among which bearings are more common. In the industry, workpieces with a diameter (or caliber) of more than Φ500mm are usually called large-diameter workpieces, and some workpieces have a diameter of more than three meters. For example: water turbines, steam turbines, large generator sets, and large bearing rings are all large-diameter workpieces. [0003] Being able to accurately measure the geometric dimensions of large-diameter workpieces is of great significance and value to pro...
