Description
Technical field
The present invention is a kind of to be used to detect on the step surface of axial step part whether have the checkout gear of expecting slag.
Background technology
In axial step part (like Fig. 1) process of precision instrument; Not only need guarantee the dimensional accuracy of part, also need keep the cleaning on the surface of part, avoid in the assembling or the course of work, scratching part because of the material slag of surface attachment; Influence part and performance of products, even cause fault.
At present, the detection of the cleannes on axial step part surface also mainly is to carry out through manual work, through the eye-observation piece surface, judges whether to exist the material slag.This method, inefficiency not only, and also in high volume production process, human eye needs the identical observation process that repeat repeatedly, and very easy fatigue not only has damage to eyes, and easy error, occurs the situation of false retrieval and omission unavoidably.Especially, process the workpiece of axial indent step for the end, light can receive blocking of edge, deposits the dash area that light can't shine on the step surface of its indent and the sidewall; These position human eyes can't directly be observed, and needing increases additional light source, and constantly adjust the orientation of workpiece; Can carry out reluctantly, not only detection efficiency is low for it, and the degree of reliability that detects is not high yet; Whole detecting operation comparatively bothers and difficulty, and is for undersize part, particularly difficult.In addition, in the process of manual detection, staff often needs contact workpiece, and this can bring harmful effect to the surface treatment of workpiece, is infected with greasy dirt, surface oxidation etc. like surface of the work, thereby influences the performance of part.
Summary of the invention
The present invention is intended to provide a kind of material slag checkout gear that can detect the axial step part of the surperficial material slag situation of axial step part easily and fast, accurately.
The material slag checkout gear of axial step part according to the invention; Comprise the video camera checkout gear that the monitor station of placing workpiece to be detected and identification part be whether qualified; The bottom of monitor station offers the workpiece inlet, and the workpiece porch is provided with by drive mechanism movable supporting plate to be opened/closed, and the below of workpiece inlet is provided with two material outlets and baffle plate; Two material outlets are respectively qualified outlet and defective outlet; Baffle plate is by the swing of another drive mechanism, and the baffle plate swing can be blocked a material outlet and another material outlet of conducting, which conducting in the position-controllable system workpiece inlet that swings to through the control baffle plate and two material outlets; Said video camera checkout gear comprises the controller of video camera and the signal that receives the video camera transmission; Controller carries out analysis and arrangement with this signal and judges whether part is qualified; And judged result issued PLC; PLC drives movable supporting plate switching and baffle plate swing according to the driving mechanism action of the driving mechanism and the baffle plate of judged result control movable supporting plate; No matter whether judged result qualified, and PLC whenever receives the driving mechanisms control movable supporting plate of a judged result through movable supporting plate and opens and closes once, workpiece is dropped from the workpiece inlet after, close again; When judged result was qualified, PLC control drive mechanism baffle plate was in and makes workpiece inlet and qualified outlet conduction position, sees off from qualified outlet from the workpiece that the workpiece inlet drops; When judged result was defective, PLC control drive mechanism baffle plate was in the position that makes workpiece inlet and defective outlet conducting, sees off from defective outlet from the workpiece that the workpiece inlet drops.
The material slag checkout gear of axial step part of the present invention, during detection, workpiece to be checked is sent to monitor station; Be positioned at the top of movable supporting plate; Taking pictures in the position to be detected of the camera workpiece of video camera checkout gear, and gives controller with the information of photograph taking, and controller contrasts this information and standard with reference to information; It is qualified to judge whether, and judged result is transferred to PLC; PLC, drives movable supporting plate and baffle plate and moves separately through their driving mechanism separately according to the driving mechanism of judged result control movable supporting plate and baffle plate.PLC whenever receives a judged result, no matter be qualified or defective, it all controls driving mechanism action of movable supporting plate, opens and closes once through the control movable supporting plate, workpiece after the detection is dropped from the workpiece inlet after, close movable supporting plate once more; For baffle plate, PLC is then in judged result when being qualified, and control drive mechanism baffle plate is in and makes workpiece inlet and qualified outlet conduction position, is seen off by qualified outlet from the workpiece that the workpiece inlet drops; When judged result when being defective, control drive mechanism baffle plate is in the position that makes workpiece inlet and defective outlet conducting, is seen off by defective outlet from the workpiece that the workpiece inlet drops.
The material slag checkout gear of said axial step part, whole testing process is accomplished by equipment automatically, and human cost is low, and its testing process is quick and easy, and testing result is reliable, be difficult for makeing mistakes.Simultaneously, the sub-material process after it detects also is automatic completion, and not only sub-material is accurate, efficient for it; And can guarantee that there are not staff touching workpiece in the surface treatment of workpiece, sub-material process, the oxidation and the adhesion grease that produce because of the staff touching can not appear in surface of the work.In addition, the accuracy of detection of video camera checkout gear is high, detects the influence that does not receive the workpiece size size, extremely is difficult to the undersize part that detects for human eye, equally can accurate detection.
