3D single-arm measuring machine with high stability

Abstract

Disclosed in the invention is a three-dimensional single-arm measuring machine with high stability. The three-dimensional single-arm measuring machine comprises a lifting device, a rotating device, a telescoping device, a measuring arm and a support device; the rotating device is fixed at the lifting device; the telescoping device is fixed at the rotating device; and the measuring arm is fixed at the telescoping device. The supporting device includes at least one support rod that is arranged at a motion path of the measuring arm, a spring arranged at the top of the support rod, a support rack connected with the top of the spring, and a support plate fixed at the support rack by a rotating shaft. According to the invention, the measuring machine has the following advantage: the support device is arranged, so that a phenomenon that the measuring arm is bent when being extended due to lack of support can be effectively prevented.

Description

technical field [0001] The invention relates to a measuring machine, in particular to a three-dimensional single-arm measuring machine with high stability. Background technique [0002] In traditional 3D measuring machines, the measuring arm needs to move in the X-axis, Y-axis and Z-axis directions. The movement in the Z-axis direction is realized by lifting the column, the movement in the Y-axis direction is realized by a telescopic device connected with the measuring arm, and the movement in the X-axis direction is realized by a slideway arranged at the bottom. [0003] Due to the need to set the slideway at the bottom, the traditional three-dimensional measuring machine occupies a large amount of space in the X-axis direction, which is not conducive to the arrangement of the equipment. [0004] In addition, in traditional 3D measuring machines, when the length of the measuring arm is longer, the center of gravity of the measuring arm will be greatly shifted outward, whic...

Problems solved by technology

[0003] Due to the need to set the slideway at the bottom, the traditional three-dimensional measuring machine occupies a large amount of space in the X-axis direction, which is not conducive to the layout of the equipment

[0004] In addition, in the traditional 3D measuring machine, when the measuring arm has a long extension length, the center of gravity of the measuring arm will be greatly shifted outward, which will affect the stability of the 3D measuring machine

At the same time, since the measuring arm is stretched out, there will inevitably be a certain bending, resulting in errors in the measurement results
