The invention provides a testing apparatus for wear conditions of location holes in a plate metal framework and a testing method thereof, belonging to the technical field of hole size measurement. The testing apparatus is characterized in that one end of a location cylinder is in fixed connection with a test platform, the other end of the location cylinder and an internal side face of an electrode ring fit tightly, and the external diameter of the electrode ring matches with the internal diameter of a location hole to be tested in a metal framework; one side of the test platform is provided with a push rod connected with a pneumatic means, and the push rod is as tall as the metal location framework. The testing method is characterized in that the metal location framework is arranged on the test platform; the ends of electrode rings on the location cylinders are arranged in the location holes in the metal location framework; when the push rod pushes the metal location framework along a direction to allow the metal location framework to contact with the location cylinders, sequentially arranged location cylinders form a series circuit because of conductivity of the metal location framework; if indicating lamps are on, the location holes prove to have no wear and be qualified, and if any location hole becomes larger due to wearing, the series circuit is disconnected, and the indicating lamps are off. The testing apparatus has a simple structure, and the testing method is convenient and practical.
Description
Technical field
The present invention relates to a kind of proving installation and method of testing thereof of wear condition of flat metal member pilot hole, belong to the aperture technical field of measurement and test.
Background technology
When using sheet type metal framework processing multiple product, generally metal framework is fixed on by pilot hole on the process equipment of product, be locating template with the sheet type metal framework, processing subsequent product repeatedly.Pull in the production run like P.e.c., the components and parts mounting hole will accurately be located, beaten to pcb board earlier, and then through chip mounter, move mounting head and place Surface Mount Component, exactly on the PCB pad.To accomplish definitely that pcb board accurately locatees; One of method is for being fixed on metal framework on the process equipment of product earlier through pilot hole; Pcb board places in the center pit of metal framework again, after punching, mount components and parts operation completion, takes out pcb board, puts into new pcb board again and repeats above-mentioned steps.Metal framework is after prolonged and repeated use, and pilot hole possibly cause the minor shifts of metal framework location because of wearing and tearing, and metal framework can't accurately be located, and causes influencing the quality of subsequent product.
In order to guarantee the bearing accuracy of metal framework, usually need be through percentage card, caliper-gauge or vernier caliper commonly used, whether the pilot hole that detects on the metal framework has wearing and tearing, but detection efficiency is very low, can not satisfy the needs that industrial automation in enormous quantities is produced.Set up a kind of device that whether weares and teares and measuring method that detects the pilot hole on the metal positioning framework fast and effectively,, very positive meaning is arranged for improving product percent of pass and production efficiency.
Summary of the invention
The objective of the invention is to, a kind of simple in structure, easy to operate flat metal framework pilot hole wear testing device and method of testing thereof are provided, so that whether the pilot hole that detects quickly and efficiently on the framework weares and teares.
For achieving the above object; The technical scheme that adopts is: a kind of flat metal framework pilot hole wear testing device; Comprise test platform and positioning cylinder; It is characterized in that: an end of said positioning cylinder is fixedly connected with said test platform, and the outside surface of the other end and the medial surface of electrode retaining collar fit tightly, and the external diameter of said electrode retaining collar and the internal diameter of pilot hole to be measured coupling are coincide; Said positioning cylinder quantity is arranged in order more than two, and the electrode retaining collar of two positioning cylinders of ordering initial and end is electrically connected with pilot lamp respectively; Place the push rod that links to each other with pneumatic means of said test platform one side, height is concordant consistent with flat metal frame height to be measured.
The other end of said positioning cylinder, periphery are equipped with a plurality of caulking grooves that are inlaid with the metal electrode pin, are uniformly distributed with, and the internal diameter coupling of external diameter and pilot hole to be measured is coincide.
Said positioning cylinder and said test platform are made by insulating material.
The method of testing of said proving installation; It is characterized in that: said metal framework places on the said test platform; Make charged polar ring one end of positioning cylinder place pilot hole on the metal framework, control said push rod to opposite side gently translation promote metal framework, till the positioning cylinder outside surface joins on pilot hole inwall and the test platform on the said metal framework; The bright expression pilot hole of pilot lamp is not worn, and is qualified.
Good effect of the present invention is: the push rod that links to each other with pneumatic means promotes the metal positioning framework gently from a direction; After framework touches the electrode retaining collar (or electrode pin) of positioning cylinder; Because the conduction of framework, the positioning cylinder that is arranged in order forms series loop, and the bright demonstration pilot hole of pilot lamp does not have wearing and tearing; Any one pilot hole is as becoming big because of wearing and tearing; Framework does not reach the electrode retaining collar (or electrode pin) of positioning cylinder, and series loop can not form, and pilot lamp does not work, and experience wear is defective for the demonstration pilot hole.Said flat metal framework pilot hole wear testing apparatus structure is simple, and method of testing is convenient and easy.
