Abstract
The invention mainly relates to a kind of positioning devices of easy material scratch measuring device, the positioning device includes by bottom plate with a scale, frame and crossbeam, the bottom plate and crossbeam are arranged in frame, the device is mainly used for the measurement of surface of plastic products scratch resistance, program repeatability and reproducibility is strong, the influence of subject people is light and small, while investing the device of fewer measurement product scratch.
Description
Technical field
The invention mainly relates to a kind of positioning device of easy material scratch measuring device, which is mainly used for moulding
The measurement of material products surface scratch resistance.
Background technique
Requirement with consumer to automobile is more and more harsher, and automotive field also puts forward new requirements material, scratch resistance
Wiping property is exactly one of them.If the scratch resistance of material is poor, plastic products in production, storage, assembly and use process, by
It is contacted in hard object, it is possible to generate scratch, seriously affect the appearance of product.The scratch resistance of material has following several measurement sides
Method: Emhorn stick method, the back-shaped skill of handling needles, five fingering and cross scrape embrocation.Emhorn stick method is exactly with the Emhorn stick for adjusting load pressure
It crosses in surface of plastic products.Estimate the thickness and color change of scratch.The advantages of this method is that equipment is simple, it is only necessary to one
Emhorn stick；It is easy to operate.The disadvantage is that subjectivity is strong, same scratch, somebody is considered qualified, and somebody is considered not conforming to
Lattice, repeatability and reproducibility is poor.It has been eliminated substantially now.The five fingers scrape embrocation and cross to scrape embrocation be with fixed negative
Load and speed, draw a series of parallel lines or cross hairs in product surface with stump is scraped, and measure scribing line front and back product with color difference meter
The color change on surface.The advantages of this method is that subjectivity is weaker, and repeatability and reproducibility is strong, and measurement result is more objective,
The disadvantage is that equipment investment is higher.
Summary of the invention
The purpose of the present invention is to provide a kind of repeatability and reproducibility is strong, the influence of subject people is light and small, throws simultaneously
Provide the device of fewer measurement product scratch.
To reach this purpose, the present invention provides a kind of following solution: easy material scratch resistance measuring device,
The positioning device of easy material scratch measuring device, which is characterized in that the positioning device include by bottom plate with a scale,
Frame and crossbeam, the bottom plate and crossbeam are arranged in frame；The bottom plate is bottom plate with a scale, the scale on the bottom plate
It is divided into a series of straight lines of 2mm between being, the width of the frame is 5-10CM, and the width of the bottom plate and crossbeam is respectively less than side
The width of frame.
Compared with the existing technology, advantages of the present invention is as follows, and it is strong that the present invention provides a kind of repeatability and reproducibility, by
The influence of gauger people is light and small, while investing the device of fewer measurement product scratch.
Specific embodiment
Below with reference to embodiment, technical solution of the present invention is described in detail, but protection scope of the present invention is not
It is confined to the embodiment.
A kind of easy material scratch resistance measuring device, the positioning device of easy material scratch measuring device, institute
Stating positioning device includes by bottom plate with a scale, frame and crossbeam, and the bottom plate and crossbeam are arranged in frame；The bottom plate is
Bottom plate with a scale, the scale on the bottom plate are divided into a series of straight lines of 2mm between being, the width of the frame is 5-
The width of 10CM, the bottom plate and crossbeam is respectively less than the width of frame.In measurement, the face in region to be measured is first measured with color difference meter
Chromatic number evidence.Then product to be measured is put into positioning device, makes one in a line and bottom plate with a scale of product to be measured
Graduation mark is overlapped, and an edge in region to be measured is under a line of crossbeam.With adjust load scrape stump along
Crossbeam draws a straight line in the region to be measured of product, and the product to be measured of movement gently makes scale adjacent on its side and bottom plate
Line is overlapped, and further along crossbeam in the standardized straight line in region to be measured of product, continues to press on product, is crossed, until will be on region to be measured
Draw full line.Product is removed, with the color data of color difference meter measurement dashed part.The color difference in the scribing line front and back region is calculated, accordingly
Judge whether the scraping property of the material meets the requirements.
