Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as figure 2 As shown, a flatness and concentricity measuring mechanism for workpieces includes a flatness measuring sleeve 1 and a concentricity measuring rod 2. The concentricity measuring rod 2 is a hollow structure, saving materials, and the flatness measuring sleeve 1 The length is the same as the distance between the two drilling and milling holes of the workpiece to be measured, and the end is a planar mechanism. If it can be smoothly placed between the two drilling and milling holes of the workpiece to be measured during use, and there is no gap on the contact surface, then Such as figure 1 The workpiece shown is qualified for flatness, the concentricity measuring rod 2 is nested in the flatness measuring sleeve 1, and the diameter of the concentricity measuring rod 2 is the same as the diameter of the drilled and milled hole, when the flatness mea...

The invention discloses a flatness and concentricity measurement mechanism for a workpiece. The flatness and concentricity measurement mechanism comprises a flatness measurement sleeve and a concentricity measurement rod; the length of the flatness measurement sleeve is the same as the distance between two drilling and milling holes of a to-be-measured workpiece, and end portions of the flatness measurement sleeve are planar mechanisms; the concentricity measurement rod is nested in the flatness measurement sleeve, and the diameter of the concentricity measurement rod is the same as the bore diameter of the drilling and milling holes; and the end portions of the flatness measurement sleeve project outwardly to form convex rings. The flatness and concentricity measurement mechanism provides convenience for measurement of flatness and concentricity of the workpiece, is convenient to use and operate, simple in structure and easy to implement, and has a good application prospect.
Description
technical field [0001] The invention relates to a mechanism for measuring mechanical workpieces, in particular to a mechanism for measuring flatness and concentricity of workpieces. Background technique [0002] After drilling and milling of mechanical workpieces, such as figure 1 The workpiece shown needs to measure the flatness and concentricity of the drilled and milled holes symmetrically arranged at the front end. At present, a simple measuring ruler is used to measure manually with the human eye, and the flatness and concentricity are measured separately. The detection efficiency Very low, time-consuming and labor-intensive. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the existing problems of low detection efficiency, time-consuming and labor-intensive problems of using a simple measuring ruler in conjunction with human eyes for manual measurement. [0004] In order to achieve the above object, the technic...
