Description
Technical field
The utility model relates to bolt Automatic Measurement Technique field, specifically relates to a kind of bolt that bolt head can be hung detection and hangs the detection index plate.
Background technology
Along with the fast development of science and technology, in Investment in fastener industry, the testing of bolt product quality by traditional manual detection, is substituted by checkout equipment miscellaneous just gradually, and this is an inevitable development trend.Than traditional manual detection, checkout equipment has: the accuracy of detection height, and error rate is little; Detection speed is fast, but non-stop run; Can effectively reduce and detect artificial input cost, improve many advantages such as market competitiveness of enterprises.The principle of work that checkout equipment detects bolt product quality quality is: utilize many technical grade video cameras, respectively to the capture of photographing of the head, neck and the screw portion that hang on the bolt on the index plate, by computing machine in conjunction with being built in detection software in the computing machine, the outward appearance of bolt and sized image compared calculate and analyze, and assign command signal so that directly unacceptable product is rejected away from detecting index plate by device for eliminating, non-defective unit and defective products automatic screening are come out the most at last.In checkout equipment, the index plate of Hanging bolt is one of important service part.The index plate structural design rationally whether, directly have influence on testing result, and the quality of examined product quality.
The index plate structure that occurs on the market is too simple at present, the more important thing is and exist technical deficiency: because index plate has certain thickness, when the head of bolt is suspended on the index plate, the camera that detects usefulness is merely able to bolt is exceeded the capture of photographing of part below the index plate thickness, and the head that aligns the bolt of the camera capture of partly photographing.And be at all can't capture for the neck camera that is suspended on the bolt that is blocked by index plate thickness on the index plate.Like this, the position of detection is affected.This structure often can only be applicable to the less demanding product of bolt is detected, for the detection that there is the specific (special) requirements bolt in the automobile industry field, can't use at all.
In order to overcome the existing technical deficiency of traditional index plate, people begin to attempt using several different methods, and attempt to solve this technical barrier, automatically detect screening machine as the disclosed a kind of bolt of China Patent No. " 02247740.3 ", its improvements are: the photography detecting unit comprises a briquetting machine, one ejecting mechanism and a photography detector, briquetting machine has one and overhangs to the pressing arm of the screw of rotary machine top and be arranged on an elasticity suppressor of pressing arm below, and ejecting mechanism has and is used for being pressed a thimble and the displacement limiter that screw that the arm compacting lives upwards ejects the irradiation hole that is aligned with light source generator.Its principle is: utilize a briquetting machine and an ejecting mechanism, tiny screw is ejected the surface of rotary machine, detect for the capture of photography detector.Be easy to find out that this utility model is created the deficiency that has overcome conventional art on principle.But this utility model is created disclosed technology, has certain deficiency also: at first structure is too loaded down with trivial details, and the cost of manufacturing, operation and maintenance is too high; Secondly, operation is long, and the production capacity in the identical time is not high; Once more, since in enormous quantities, long-time non-stop run, briquetting machine and ejecting mechanism are easy to damage, and serviceable life is limited; At last, for more tiny screw, be difficult to realize compacting and the stability that ejects, or when suppressing and ejecting, escape phenomenon very easily occur, and then influence detects quality.
The appearance of a kind of simple, science rational in infrastructure, practical index plate for the bolt detection range, seems extremely necessary.
The utility model content
The technical matters that the utility model solved be to provide a kind of simple in structure, economical and practical, be convenient to operation, and can easily realize the head of bolt is hung, the bolt that detects for camera photography capture hangs and detects index plate.
The technical matters that the utility model solved realizes by the following technical solutions:
Bolt hangs and detects index plate, comprise one division dish body, be provided with a power shaft mounting hole in the middle of the described index plate body, also be provided with fixed orifice in described power shaft mounting hole periphery, it is characterized in that: described index plate body bottom is formed with the following back light groove of a detection bolt shank, outer, the bottom five equilibrium of described index plate body is outward extended with numerous support arms, form bolt shank photography optical channel between adjacent two described support arms, be used for the parameters of bolt screw portion is detected, the outer end of every described support arm also extends upward formation one bolt head and raises piece;
Described bolt head is raised and is also formed back light groove on a detection bolt head and the neck between piece and the described index plate body, be used to place back light, adjacent two described bolt heads are raised and are also formed a bolt head and neck photography optical channel between the piece, be directly used in size to the R of bolt head and bolt head and screw rod connection place neck, whether perfect thread detects to parameters such as screw rod roots, raise at adjacent two described bolt heads and also to be provided with a block between the piece, the outer of described block also forms an arc groove that matches with the feeding bolt shank.
Described support arm stretches out perpendicular to the outer, bottom of described index plate body, and is connected as a single entity with described index plate body.
Described bolt head is raised piece and is extended upward perpendicular to the outermost end of described support arm, and is connected as a single entity with described support arm.
The outer, upper end that described bolt head is raised piece also stretches out perpendicular to the lower end that described bolt head is raised block body.
