A ballbar fixture applied to multi-axis machine tools and machining centers

Abstract

The invention discloses a ball arm instrument clamp applied to a multi-axis machine tool and a processing center and belongs to the technical field of measurement. According to the specific technicalscheme, the ball arm instrument clamp comprises a bottom plate, a telescopic rod, a connecting rod, a front section strip and a magnetic ball bowl, wherein the magnetic ball bowl is mounted at one endof the front section strip; the other end of the front section strip is mounted at one end of the connecting rod; the other end of the connecting rod is fixed on the telescopic rod; the telescopic rod is fixed on the bottom plate; the bottom plate is fixed on the machine tool; the front section strip and the connecting rod are mutually perpendicular; and the center line of the magnetic ball bowlis perpendicular to the front section strip and the connecting rod. Through determining the position of the clamp once, the ball arm instrument can carry out measurement in multiple planes; and the ball arm instrument clamp has the advantages of being simple and convenient to operate and high in mounting precision.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a ballbar fixture applied to multi-axis machine tools and machining centers. Background technique [0002] With the rapid development of modern manufacturing industry, multi-axis machine tools and machining centers have been widely used in aviation, aerospace, automobiles, medical equipment and other fields. Especially in the processing of impellers, blades, steam turbine rotors, crankshafts, molds and other parts, multi-axis machine tools and machining centers have incomparable technical advantages, and through multi-axis linkage processing, multiple clamping can be avoided and the cost of fixtures can be reduced. Improve processing efficiency and reduce the impact of installation errors on processing accuracy. The errors of the multi-axis machine tool and the machining center itself will cause the size and surface defects of the processed parts, such as geometr...

Problems solved by technology

[0010] (2) It is difficult to find a suitable location to place the magnetic ball bowl assembly

[0012] (4) The method of installing the ballbar with only two magnetic bowl assemblies has poor versatility

When the operator wants to measure multiple machine tools, especially when measuring multiple machine tools with different layouts and different strokes, the installation positions of the two magnetic ball bowl assemblies are different, and the operator needs to find a suitable installation position many times, which is very difficult. cumbersome

[0013] (5) The installation accuracy is not accurate enough

[0014] In the prior art, in the process of installing the ballbar, in order to meet the height and length requirements, some spacers or extension rods may be temporarily found for use. These temporary patchwork transition pieces may have problems such as poor surface quality and serious elastic deformation. Affect the installation accuracy
