Description

The automobile frame on-line measuring device
Technical field
The utility model relates to a kind of automobile frame on-line measuring device, particularly a kind ofly to the truck frame longeron, adopts many orders camera to carry out the device of untouched online inspection.
Background technology
Can the quality of vehicle frame manufacture not only is related to the car load Assembling Production normally move, and also is related to the driving safety of car load.The pilot hole that two longerons of truck frame need to be processed reaches up to a hundred; in process; often there will be due to drift; the reasons such as broken drill or processing omission cause hole crudy defect; due to truck frame longeron length, 3m to 12m does not wait, and the backwardness of truck frame lateral bending detection means can't meet the crudy requirement.With above-mentioned mass defect longitudinal beam enter in the production assembling process, will have a strong impact on vehicle driving safety, also can cause very large economic loss to enterprise.
Because the position in the hole on the truck frame longeron does not have the obvious regularity of distribution, cut longeron length longer, the domestic quantity that generally adopts the manual detection target hole such as photoelectric sensor or magnetic switch at present.Be difficult to detect in time the processing quantity defect problem portalled.At present the position dimension in the aperture size of the processing on longitudinal beam and hole is detected two kinds of three-dimensional coordinates measurement machine testing and manual detection are arranged, be subject to the speed of production restriction, above-mentioned two kinds of detection methods are only suitable for, in the longeron sampling Detection, can not meeting the online detection requirements of the bulk article on production line.
The detection means of current domestic truck frame lateral bending and distortion is mainly to adopt pen machine and tape measure, these two kinds of methods all can't detect the concrete numerical value of lateral bending, can't for further improve the vehicle frame manufacturing process provide can foundation the detection data, can't adapt to the requirement that vehicle frame is produced.
Abroad, the detection method that solves the crudy of longitudinal beam has adopted mechanical vision inspection technology, has realized the online detection of bulk article.Because longitudinal beam Machine Vision Inspecting System price is higher, most domestic truck manufacturing enterprise not yet adopts this advanced person's pick-up unit to be detected the longitudinal beam of automobile frame crudy at present.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile frame on-line measuring device, it can overcome the various errors that manual detection causes, realize the detection of porose of institute, the longitudinal beam of automobile frame crudy can be detected fast and accurately whether qualified, can detect the position of automobile frame left-right longeron circular hole, radius, circularity, the flatness of left-right longeron top airfoil, frame width, catercorner length, the data such as pin-and-hole right alignment, meet the demand of production scene, detects stable performance, precision is high, and speed is fast.Effectively improve industrial detection level and production efficiency.
The technical solution of the utility model is achieved in that the automobile frame on-line measuring device, it is characterized in that: on platform base, there is guide rail both sides, platform base is with shock attenuation device, mobile working platform is positioned on platform base, and the mobile working platform bottom coordinates with guide rail, in the middle of mobile working platform, is engraved structure, on its both sides inwall, tooth bar is arranged, motor is fixedly connected on platform base, the tooth bar engagement on motor gear and mobile working platform, said structure formed automobile vehicle frame conveying device, the darkroom casing covers on automobile frame conveyer one end top, the darkroom casing is the semi-closed structure that transparent materials forms, two LED lamp boxes are fixedly connected on respectively on the inwall of casing both sides, darkroom, the top camera mount is arranged in the darkroom casing between the automobile frame conveyer, be fixedly connected with the top video camera on two top camera mounts, the line laser sensor, the top camera position is vertical corresponding above the automobile frame conveyer, the line laser sensor is positioned at the both sides of top camera mount, bottom shooting rack arrangement is below the automobile frame conveyer, be fixedly connected with the bottom video camera on bottom shooting support.
The beneficial effects of the utility model are: solved the deficiency of current manual detection, overcome the various error problems that manual detection causes, can detect the porose position of institute on longitudinal beam simultaneously.The precision, speed and the stability that detect have been improved.Detection level and the production efficiency of longitudinal beam have effectively been improved.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
