Horizontal arm type three-coordinate measuring and ruling machine

Abstract

The invention discloses a horizontal arm type three-coordinate measuring and ruling machine, which includes a base, an upright column and a horizontal arm, wherein the upright column and the horizontal arm are made of lighter material, namely aluminum; all three shafts adopt two sets of linear slides; and the linear slide of the horizontal arm is mounted by adopting two mutually vertical surfaces, and an adjustable pull rod is mounted in the horizontal arm for adjusting the curve and deformation caused by other causes as self weight. The horizontal arm type three-coordinate measuring and ruling machine solves the problems in the market that the existing three-coordinate ruling machine has unstable mechanism, complex structure and high cost, and is complex to machine the parts and inflexible to operate. The shafts are mutually vertical and matched with the precise linear slides to realize the three-dimensional movement, so as to achieve the measuring and ruling functions in the three-dimensional space; and the three-coordinate measuring and ruling machine can support all sorts of triggering, analog scanning and non-contact optical measuring heads, and can be widely applied to the measuring and ruling of large mechanical parts as automobiles, motorcycles, excavators, ship engines and dies.

Description

technical field [0001] The invention relates to the technical field of measurement and marking, in particular to a horizontal arm type three-coordinate measuring and marking machine. Background technique [0002] A three-coordinate measuring machine has a detector that can move in three directions and can move on three mutually perpendicular guide rails. The detector transmits signals in a contact or non-contact manner. Optical ruler) An instrument that calculates the coordinates (X, Y, Z) of each point of the workpiece and the measurement of various functions through a data processor or computer." The measurement functions of a three-coordinate measuring machine should include dimensional accuracy, positioning accuracy, geometric accuracy And contour accuracy, etc., mainly used for the measurement of dimensional error and shape error of parts and components, and plays an important role in ensuring the quality of products. The three-coordinate measuring machine is a derivati...

AI Technical Summary

Problems solved by technology

Although this structure is suitable for the working environment in production and has good rigidity, the weight of the components is relatively large, and the horizontal arm and column are prone to deflection due to their own gravity, which affects the accuracy of measurement or marking. In addition, long-term use of marking line device, it is also easy to reduce the measurement accuracy of the device

[0004] There are also three-coordinate measuring liners that use rolling bearings on the frame in order to meet the lightness of operation, but this makes it difficult to achieve the required measurement accuracy, poor mechanical wear resistance, and relatively weak stability when using the line-scribing function. Affects the use of measurement functions

In addition, the processing technology requirements of the whole mechanism are relatively high, and the cost is relatively high, which is not conducive to the current market demand
