Abstract
The utility model discloses a bad installation detection fixture for an on-off key, which is a steel column composed of three sections of circular steps whose inner diameters are gradually reduced. Circular centers of the three sections of circular steps are in the same straight line; and the three sections of circular steps are sequentially a fixture body with the largest inner diameter, a no-go gauge with the middle-sized inner diameter and a go gauge with the smallest inner diameter from the top bottom. According to the bad installation detection fixture for an on-off key, the operation is simple and good products and defective products are obviously distinguished; the standards are obvious, products manufactured after bad installation is stopped have no bad phenomena; operation by the working staff is facilitated, and the labor intensity of the working staff can be greatly lessened; bad installation can be stopped, the quality can be ensured, and the production yield can be improved; tediousness of former measurement tools such as visual measurement or a ruler can be improved, the measurement errors can be reduced, labor cost can be saved, and effects of getting twofold results with half the effort can be achieved; bad installation manually detected can be eliminated, operation is facilitated, bad scraps can be reduced to 0 from about 6PCS each day, product scraps can be saved, and the scrap cost each month can be saved by 2315yuan.
Description
Technical field
The utility model belongs to endoporus Pore Diameter Detection tool technical field, relates to specifically a kind of on & off switch bad detection tool is installed.
Background technology
Conventionally in prior art, the on & off switch of various electronic products is all to adopt circular on & off switch, and institute is also circle for placing the position, hole of on & off switch.In prior art, be all hot pressing in batch or injection mo(u)lding conventionally for the workpiece of on & off switch is installed, the common hole of these workpiece is biased little, fraction defective is higher, operator detects workpiece by measuring tools such as visual or slide calliper rule, and the examination criteria of these methods is indefinite, is all to detect by workman's experience conventionally, manual operation inconvenience, operation intensity is larger, easily undetected and occur that defective products, hot melt power supply are turned on light and make cannot repair and cause card key to scrap after product hot melt.
In practical operation, often cause after assembling product the phenomenons such as card key when workman's assembled switch key because position, hole size is less than normal, thereby cause whole workpiece to scrap, and the internal diameter personnel of circular port position are difficult for inspection, make defective products every day in operation in the past a lot of.Because assembled switch key is all in the second half section of production line flow process conventionally, the workpiece that the detachable maintaining of product is produced leading portion is scrapped, so can cause the waste of a large amount of manpower and materials.Need badly now and make a kind of auxiliary fixture, with after by poorly controlled at first stop, so not only convenient working but also make bad scrapping be down to zero and scrap, thus use manpower and material resources sparingly cost.
Summary of the invention
The purpose of this utility model is the deficiency existing in order to overcome prior art, provide a kind of position, imitative type hole that utilizes holes of products position inside casing size and manufacture to detect tool, its be a kind of simple in structure, tackle on & off switch bad, guaranteed quality bad detection tool be installed.
The utility model is achieved through the following technical solutions: a kind of on & off switch is installed bad detection tool, it is the steel column that the step cutting pattern that reduced successively by three sections of interior diameters forms, the center of circle of three sections of step cutting patterns on same straight line, the no-go gage that tool body, interior diameter that three sections of step cutting patterns are followed successively by interior diameter maximum are from top to bottom placed in the middle and the drift of interior diameter minimum.
The described steel column steel column that is formed in one.The interior diameter of tool body is 15mm, and the interior diameter of no-go gage is 10.16mm, and the interior diameter of drift is 10.13mm.The height of three sections of step cutting patterns is 10mm.
The utility model is a kind of detection tool for detection of endoporus aperture fraction defective, when use, by the different drift of inner diameter size and no-go gage, the pore size of existing product detected, to determine that size is whether within margin tolerance:
If a drift passes through, no-go gage does not pass through, and judges that this aperture is qualified;
If b drift passes through, no-go gage also passes through, and judges that this aperture is bigger than normal;
If c drift does not pass through, judge that this aperture is less than normal.
The beneficial effects of the utility model are: the utility model uses steel cylinder material to make the circle that meets room diameter, is divided into two sections of steps, interior diameter no-go gage step and external diameter drift step.Conventionally the surperficial thickness of product after spraying paint for twice causes the less than normal or injection moulding of aperture size to shrink to cause aperture size bad etc., the visual difficult inspection of operating personnel, cause after Product Assembly the bad phenomenon such as card key to occur, need carry out detachable maintaining, easily cause bad scrapping.Use the utility model to use tool fool proof replacement personnel inspection, to make up the visual error shortcoming of personnel.The utility model improved in the past with the measuring tools such as range estimation or slide calliper rule loaded down with trivial details, reduced error in measurement, saved human cost, play a multiplier role.The utility model is made simple, and the Kong Weifang type tool personnel of stopping check bad, convenient working, bad scrap by every day about 6PCS be reduced to 0PCS, thereby save product rejection, with monthly saving 2315 yuan of scrap cost after tool.
The utility model also tool has the following advantages: 1, simple to operate, non-defective unit and substandard products are distinguished obviously; 2, standard is clear and definite, effectively tackles the product making after bad without bad phenomenon; 3, tool is convenient to employee's operation, can alleviate greatly employee's operation intensity; 4, tackle bad, guaranteed quality, improve produce yield.
Brief description of the drawings
Fig. 1 is the side structure schematic diagram that the utility model on & off switch is installed bad detection tool;
Fig. 2 is the use status architecture schematic diagram that the utility model on & off switch is installed bad detection tool:
In figure: 1-tool body; 2-no-go gage; 3-drift.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of on & off switch is installed bad detection tool, it is the steel column that the step cutting pattern that reduced successively by three sections of interior diameters forms, the center of circle of three sections of step cutting patterns on same straight line, the no-go gage 2 that tool body 1, interior diameter that three sections of step cutting patterns are followed successively by interior diameter maximum are from top to bottom placed in the middle and the drift 3 of interior diameter minimum.The steel column steel column that is formed in one.The interior diameter of tool body 1 is 15mm, and the interior diameter of no-go gage 2 is 10.16mm, and the interior diameter of drift 3 is 10.13mm.The height of three sections of step cutting patterns is 10mm.Fig. 2 is that detection tool of the present utility model is applied in the on & off switch Pore Diameter Detection of notebook computer, is illustrated in figure 2 drift 3 not by entering switch keyhole position, the defective products that testing result of this workpiece is Kong Wei little.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement, does not all depart from essence and the scope of technical solutions of the utility model.
