Description
Technical field
The present invention relates to field of measuring technique, especially relate to a kind of measurement apparatus to stalloy thickness.
Background technology
Stalloy is the ferro-silicium of a kind of silicon content 0.5%～4.8%.It is a kind of soft magnetic materials being widely used at electrical field, is mainly used in motor, electromotor, transformator, electromagnetic mechanism, relay electronic device and measuring instruments.Electrician is generally rolled into standard-sized big sheet material with stalloy or band uses.The thickness evenness of stalloy is a very important quality characteristic.If stalloy central authorities are too big with the difference in thickness at edge, or the thickness variation of stalloy length direction is too big, all can have influence on the thickness unshakable in one's determination after assembling.Different thickness unshakable in one's determination, the variation of its permeance is also big, directly influences the characteristic of motor, electromotor, transformator, and the Thickness sensitivity in therefore stalloy being produced and used is particularly important.
The thickness detecting method of thin steel sheet is generally divided into contact type measurement and non-contact measurement two kinds.Owing to sheet material can be caused certain damage by contact measuring thickness device, therefore being applicable to off-line measurement, on-line measurement typically uses non-contact measurement.Utilizing laser-CCD thickness measuring is conventional contactless measurement.Chinese patent application publication No. CN103063151A, April 24 2013 Shen Qing Publication day, the patent of invention of entitled " a kind of thickness measurement with laser c-type frame mechanism and adjustment using method ", disclose a kind of thickness measurement with laser c-type frame machine structure.A kind of thickness measurement with laser c-type frame mechanism, including c-type frame housing, upper laser sensor, lower laser sensor it also include upper angle moving stage group, inferior horn moving stage group, the next moving stage group, upper laser sensor is connected to c-type frame housing upper by upper angle moving stage group, and lower laser sensor is connected to c-type frame lower housing portion by inferior horn moving stage group, the next moving stage group；Upper angle moving stage group, inferior horn moving stage group are made up of two adjustment direction orthogonal angle moving stage respectively, and the next moving stage group is made up of two orthogonal displacement platforms of adjustment direction.It is mounted with special adjusting apparatus by gathering the upper-lower position of the laser sensor of data two, C-shaped frame front end, and utilize the light can be with this physical features of display beams path in suspension, being adjusted laser sensor, the data detected by the most upper and lower two laser sensors are in the optimum measurement required precision that can reach this sensor static, the most lower.This structure needs to dispose two laser sensors gathering data in C-shaped frame front end, and during calibration, required precision is higher, owing to equipment self vibration the most accurate also can have a strong impact on laser instrument measurement result, therefore is not suitable for the application of factory's online production.
For the stalloy for high-power transformer, stalloy width controls at 40cm when producing.Its thickness is more uniform, does not typically have and phenomenon is increased dramatically, but there will be a range of smooth transition, and owing to process for surface coating is superior, stalloy surface reflectance is preferable, can test thickness by luminous reflectance class method.Chinese patent Authorization Notice No. CN202485637U, authorized announcement date on October 10th, 2012, the utility model patent of entitled " a kind of sheet material online dynamically non-contact laser thickness measuring system ", disclose a kind of sheet material dynamic noncontact thickness measuring structure online.It includes several laser feelers being positioned at above one of them roller of plate-extruding machine outfan, laser feeler vertical irradiation is in the top of roller bus, several laser feelers are all connected with an industrial control host, and the plate-extruding machine that sheet material is departed from roller by the outfan of industrial control host respectively with acoustic-optic alarm and performs device and is connected.This utility model is arranged above several laser feelers at one of them roller of plate-extruding machine outfan, laser feeler is connected with industrial control host, operator can arrange the thickness upper lower limit value of product in industrial control host, can send sound and light alarm when thickness transfinites.This structure has the thickness of several laser head sheet material measurements above roller, is in fact not required to, because multiple laser instrument is only to ensure that the accuracy of final measured value.If final measurement exceedes certain value, need to stop conveying sheet material, process.Additionally the sheet material of this structure is it cannot be guaranteed that be adjacent to roller completely and do not have space, adds introducing error term, and the credibility of measurement is relatively low.
