Description
Technical field
The utility model belongs to measures the detection technique field, relates to the accurate detection system of roller physical dimension, and the precision that is mainly used in the roller physical dimension detects.
Background technology
Bearing is extremely important and use mechanical part very widely in the mechanical industry, and its production lot is big, accuracy requirement is high.At present; China most of Production of bearing producer still relies on surveying instruments such as mechanical type, optical profile type to carry out in the context of detection of bearing roller dimensional accuracy; Means are relatively backward, and the random sampling detection method detection efficiency of this dependence manpower is low, precision is low, be easy to cause personal error; Along with the development of modern manufacturing industry, traditional detection technique can not satisfy its needs.In order to adapt to the characteristics that the bearing manufacturing production lot is big, quality requirements is strict, the detection task is heavy, and during pipelining, realize the detection target of product " zero rejection rate ".
The geometric parameter of roller is an important evidence of judging that the roller physical dimension is whether qualified, and the geometric parameter of roller mainly comprises: the radius of a certain height section of roller, corresponding to certain any radius error on this cross-sectional periphery, and as shown in Figure 3.The detection of roller physical dimension at present also rests on detection mode manual, contact at home basically.Major part adopts milscale or differential transformer transducer carries out contact measurement.The manual measurement method of this traditional type is strong to operating personnel's dependence; Labor strength is bigger; Efficient is low; The more important thing is that the product precision can not get effective guarantee, also possibly produce a lot of artificial errors, so just be difficult to satisfy in enormous quantities, fast pace, high-precision product detects requirement.Because the general precision of process equipment of China's roller is not high, consistance is poor, and the precision major part of roller is to grade by checkout equipment, quality that is restricting China's bearing products and output that this is serious.The high-speed research that detects also is in the blank stage at present for bearing roller physical dimension contactless high-precision.
The processing of external bearing roller and detection mode and China Bearing Factory are different.Because the forging bed of external processing rolling body and the machining precision of cylindrical grinder generally are higher than China, the roller that therefore processes can guarantee precision and consistance preferably.But price is very expensive, can not be accepted by most of domestic Mechanical Manufacturing Enterprises.Can adopt its product quality of mode better controlled of sampling observation through the roller precision is carried out regular monitoring, the testing apparatus of its sampling observation also is to adopt the metering system of contact.Can not realize production scene large-scale application and real-time online detection, can not be from changing the state that detection means falls behind in essence.
Summary of the invention
The objective of the invention is to propose the accurate detection system of a kind of roller physical dimension in order to solve existing not high, the precision problem of lower of roller physical dimension detection method efficient, speed is fast, and measuring accuracy is high, is applicable to the upward online detection of high speed of industry.
The utility model adopts following technical scheme:
The accurate detection system of a kind of roller physical dimension, it is characterized in that: it comprises scanning system and computer data processing system; Said scanning system comprises that the scanning platform and the Liang Tai that place roller to be measured are oppositely arranged on scanning platform both sides three-dimensional laser scanner; Said computer data processing system comprises data acquisition module and data processing module; The output terminal of said two three-dimensional laser scanners all is connected with data acquisition module, and data acquisition module is connected with data processing module.
Said two three-dimensional laser scanners are placed relatively.
The utlity model has following advantage:
The utility model can be realized the on-the-spot high precision of roller geometric parameter, obtain fast; And roller geometric parameter values and the design load obtained compared; According to comparative result qualified/defective roller is separated, thereby the precision that realizes the roller physical dimension detects.
This pick-up unit, every product detect only needs 10s, can detect 6 products in one minute, one hour 360, can reach one day 24 hours uninterrupted detections, can detect 8640 in one day.It is thus clear that its detection efficiency is high.
The precision of this pick-up unit reaches as high as 0.02mm.And prior art does not generally reach this precision.
Therefore the utility model industrialization degree is high, and measuring accuracy is high, is applicable to that the industrial online contactless high-precision of high speed of going up detects.
