Abstract

A high-stability long cantilever type coordinate measuring machine comprises a Y-direction guiding track, a transmission device and a supporting component. A Y-direction sliding plate is fixed on the transmission device. A stand column is arranged on the Y-direction sliding plate. A Z-direction sliding plate is arranged on the stand column in a sleeved mode. The Z-direction sliding plate is fixedly provided with a horizontal X-direction sliding plate which comprises four long guiding track air bearing devices connected to form a long cube box structure. An X-direction transmission device is arranged at one end of the X-direction sliding plate. A horizontal cantilever beam is arranged in the X-direction sliding plate. The machine moves in the X direction by driving of the X-direction transmission device which contains a clamping and guiding leather roller. The high-stability long cantilever type coordinate measuring machine improves moving stability and the straightness and the rigidness of the cantilever beam and the stand column, the innovative design of a transmission mechanism, a supporting mechanism, a cantilever structure and a stand column structure is determined, measuring accuracy can be greatly improved to 7 + 5 L / 1000microns, the high-stability long cantilever type coordinate measuring machine belongs to high-accuracy long cantilever measuring machines in domestic and foreign markets, and the measuring accuracy index is in a leading level.

Description

technical field [0001] The invention relates to a three-coordinate measuring machine, in particular to a highly stable long cantilever type three-coordinate measuring machine. Background technique [0002] The cantilever type three-coordinate measuring machine has the advantages of compact structure, wide measuring working space and low manufacturing cost. Comparison. Research on cantilever structure measuring machines has been carried out at home and abroad for a long time, but the cantilever structure will be deformed due to the influence of its own weight, and the deformation will increase with the extension of the cantilever. The cantilever stretches out and is bent by a large torque, which will seriously affect the measurement accuracy, so the cantilever structure is only used in manual measuring machines and marking machines that require low measurement accuracy, which limits its scope of use. In recent years, cantilever measuring machines - especially long cantileve...
