Description
Technical field
The utility model relates to a kind of cubing, particularly a kind of for checking the cubing in bore aperture.
Background technology
At present, the method that bore aperture is detected has following several conventionally: 1, use slide calliper rule, dial bore gage directly to read size, but that its defect is accuracy of detection is low, and can not measures the form and position tolerance of endoporus; 2, use three coordinate measuring machine, although it can the higher hole of accuracy of detection, cost is too high, is not suitable for batch production; 3, use universal tool-measuring microscope, although its accuracy of detection is moderate, can only detect orifice diameter, cannot detect form and position tolerance to situation in hole, and efficiency is low, cost is high, is not suitable for produced on-site; 4, use air-gauge, as gauging spindle etc., but there is greatly limitation in the product that gauging spindle can only be through hole for detection of endoporus; 5, use micrometer inside caliper, because it can directly read endoporus aperture, and cost is low, be current the most frequently used endoporus measurer, but its shortcoming is to measure endoporus form and position tolerance.For the comparatively special gear of some inner hole structure, as shown in Figure 7, this gear 5 according to actual operation requirements except being processed with endoporus 5a, also be processed with respectively via hole 5b at the two ends of endoporus 5a, and the diameter of via hole 5b is less than the diameter of endoporus 5a, while detection in the endoporus aperture to this type gear like this, in the situation that there is no appliance special for detecting, can only use micrometer inside caliper and roundness measuring instrument to detect, in the time detecting, need first allow differential head and the measurement contact of micrometer inside caliper that via hole just can be entered in endoporus, endoporus aperture is measured, it is very inconvenient to use, waste time and energy, inefficiency, and measuring with micrometer inside caliper behind the endoporus aperture of this gear, also need that this gear is transplanted on to accurate measurement chamber roundness measuring instrument and carry out circularity, the detection of cylindricity, so not only cost is high, efficiency is low, it is not convenient to operate, and be only suitable for the inspection in single-piece production, be not suitable for the inspection of on-the-spot batch production.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of for checking the cubing in bore aperture, it is simple in structure, quick and easy to use, improve work efficiency, and can replace routine check micrometer inside caliper used and roundness measuring instrument, realize the verification and measurement ratio to product 100%, be applicable to the inspection of on-the-spot batch production, effectively improved the qualification rate of product, can also be cost-saving.
The purpose of this utility model is achieved in that a kind of for checking the cubing in bore aperture, comprise three independently locating piece and the taper plug gauges for coordinating with locating piece of sector shape, three locating pieces surround 3/4 cylinder centered by the center of circle of each locating piece, the medial surface of each locating piece is dip plane, and an end face of the medial surface of each locating piece is respectively equipped with the along inclined direction outer boss that stretches out locating piece, make 3/4 cylinder that three locating pieces surround in be formed centrally bellmouth, on the lateral surface of each locating piece, be respectively equipped with groove, the small end of described taper plug gauge inserts in bellmouth, one side of the large end of taper plug gauge is provided with breach, the lower end of this breach is go side, upper end is not-go-end.
The external diameter of 3/4 cylinder and the internal diameter of bore that three locating pieces surround equate.
The height of described locating piece lateral surface equals the axial length of bore.
Described groove is positioned at the middle part of locating piece lateral surface, and the oilhole being provided with gear is corresponding.
The diameter of described taper plug gauge small end is less than the diameter of bellmouth small end.
The diameter of the go side of the large end of described taper plug gauge and the equal diameters of the large end of bellmouth, the diameter of the not-go-end of the large end of taper plug gauge is greater than the diameter of the large end of bellmouth.
The end face of the large end of described taper plug gauge is provided with handle.
Adopt technique scheme: because the utility model comprises three independently locating piece and the taper plug gauges for coordinating with locating piece of sector shape, three locating pieces surround 3/4 cylinder centered by the center of circle of each locating piece, the medial surface of each locating piece is dip plane, and an end face of the medial surface of each locating piece is respectively equipped with the along inclined direction outer boss that stretches out locating piece, make 3/4 cylinder that three locating pieces surround in be formed centrally bellmouth, on the lateral surface of each locating piece, be respectively equipped with groove, the small end of described taper plug gauge inserts in bellmouth, one side of the large end of taper plug gauge is provided with breach, the lower end of this breach is go side, upper end is not-go-end, like this in the time that needs detect bore aperture, three locating pieces can be packed in the endoporus of gear to be measured in any order one by one, because three locating pieces pack in the endoporus of gear one by one, can avoid the interference of the two ends via hole of bore, make the locating piece can be light, pack into fast in bore, and the outside of locating piece can be close to the hole wall of bore, thereby the accuracy requirement of bore to be detected is transferred on locating piece, utilize locating piece directly bore to be detected, after three locating pieces install, only taper plug gauge need be inserted in the bellmouth of 3/4 cylinder that three locating pieces surround, can utilize go side and the not-go-end of the large end of taper plug gauge to detect whether bore is qualified, in the time that the position of the upper surface of the boss of locating piece is between the go side of the large end of taper plug gauge face and not-go-end face, product is specification product, otherwise be substandard product.
The external diameter of 3/4 cylinder and the internal diameter of bore that surround due to three locating pieces equate, make locating piece lateral surface can with the hole wall close contact of bore, improved the accuracy detecting.
Because the height of described locating piece lateral surface equals the axial length of bore, locating piece landing from bore not only can be prevented like this, and the no matter positive and negative placement of gear can be ensured, all can use locating piece to detect, use convenient.
Because described groove is positioned at the middle part of locating piece lateral surface, the oilhole being provided with gear is corresponding, like this after testing product completes, the oilhole of available elongate article (as the shank of steel wire or discarded drill bit etc.) on gear inserts in the groove of locating piece, by elongate article, locating piece is pushed up from bore, thus more quick and easy taking-up locating piece.
