Embodiment Construction

[0028] A kind of surface roughness measuring device embodiment, such as Figure 1~4 As shown, it includes a marble base 12, a measuring workbench fixed on the upper surface of the base 12, a marble column 2 fixed on the upper surface of the base 12 and positioned in the middle of one side of the dimension measuring workbench, and a vertical movement on the column. The laser measurement mechanism, the measuring workbench includes two layers of platforms, each of which includes a linear guide movement pair, and the upper stage has a set of linear guide movement pairs, including a fixed guide rail 13 and a corresponding The fixed guide rail 13 guides the matched air-floating guide rail 11. The air-floating guide rail 11 is provided with a workpiece fixing platform 5, and the lower platform has two sets of linear guide moving pairs arranged in parallel, including two fixed guide rails 8, 8' and corresponding fixed guide rails. The guide rails 8, 8' guide the two air-floating guide...

Abstract

The invention provides a measurement device for surface roughness, comprising a measurement mechanism and a measurement workbench, wherein the measurement workbench consists of an upper-layer rack and a lower-layer rack, each layer of the rack comprises a linear guide sliding pair, each linear guide sliding pair comprises a fixed guide rail and an air-floating guide rail, each air-floating guide rail consists of an upper air-floating block, two side air-floating blocks fixedly connected with two sides of the bottom of the upper air-floating block and two bottom air-floating blocks which are fixedly connected with the bottoms of the two side air-floating blocks and oppositely extend respectively, the inner surface of each air-floating guide rail consists of air outlet surface of each air-floating block, air outlet holes are arranged on the air outlet surfaces which are opposite to the fixed guide rails, and the air outlet holes of the air-floating blocks are communicated with one another in the air-floating guide rails by gas passageways and jointly use one air inlet hole; and the invention further provides the measurement workbench. The air-floating guide rails formed into the measurement workbench can move along with the fixed guide rails without friction, so that the problem that the measurement workbench in the prior art is slow in response speed, low in moving speed and low in control precision can be solved.

Description

technical field [0001] The invention relates to a surface roughness measuring device. Background technique [0002] Surface roughness has a great influence on the assembly, sealing, fatigue, wear, corrosion, noise, etc. of the parts. It is one of the important contents to evaluate the surface quality. Therefore, it is necessary to carry out objective and scientific detection of the surface roughness of the workpiece And evaluation, has already become an important topic in the field of processing. [0003] At present, most of the roughness detection at home and abroad still use contact stylus profiler. The disadvantages of contact measuring instrument are: [0004] (1) The hardness of the diamond measuring head is generally very high, so the measuring head is not easy to wear quickly, but it is easy to scratch the workpiece when measuring the surface of the workpiece, so it is not suitable for measuring the surface of high-quality and soft materials. [0005] (2) In order t...
