Multi-sensor quick dismounting device based on three-coordinate measuring machine and use method

Abstract

The invention discloses a multi-sensor quick dismounting device based on a three-coordinate measuring machine and a use method. At present, a commercial CMM is generally fixedly provided with a type of sensors, and the diversity of measurement requirements cannot be met. The multi-sensor quick dismounting device comprises a magnetic base module, a common connector base module and a special connector module which are sequentially connected from top to bottom. The magnetic base module comprises a base, a rotating disc, a permanent magnet, a middle frame, a first magnet yoke, a magnetic isolation belt and a second magnet yoke. The common connector base module comprises a common base. The special connector module comprises a Morse taper shank and a measuring sensor. According to the invention, by adjusting the magnetic poles of the permanent magnets above the two separated magnet yokes, the adsorption force of the magnet yokes to the special connector module below the magnet yokes is adjusted, so that the special connector module is stably adsorbed, and meanwhile, different measurement sensors can be quickly switched. And the CMM application range is expanded. In addition, the multi-sensor quick dismounting device can be obtained by upgrading and transforming a measuring head mounting structure on the basis of an existing CMM.

Description

technical field [0001] The invention belongs to the field of geometric quantity measurement of complex parts, and in particular relates to a multi-sensor quick disassembly device based on a three-coordinate measuring machine (Coordinate Measuring Machine, CMM) and a use method thereof. Background technique [0002] The field of CMM geometric quantity measurement is usually divided into two methods: contact measurement and non-contact measurement. Among them, contact measurement uses a contact probe to collect data point by point, and the measurement accuracy is high, but the measurement process is cumbersome and the efficiency is low; non-contact measurement usually uses laser displacement sensors, confocal displacement sensors, image probes, etc. Acquisition, measurement accuracy is lower than contact measurement, and there are more measurement dead angles, but the measurement speed is fast. [0003] At present, commercial CMMs are generally fixedly installed with a type o...

Problems solved by technology

However, such commercial products are expensive, and the size and specifications of the sensors are strictly limited. Only the special sensors independently developed by the manufacturer can be used. The maintenance cost is high, and the interchangeability cannot be satisfied, which increases the measurement cost to a certain extent.
