Abstract
The invention provides a detecting tool for a hole, relating to a plug gauge and aiming at solving the problem that parts cannot be gradually detected one by one before warehoused to cause high reject rate of the parts because one hole is detected twice to consume detecting hour when the traditional plug gauge for detecting an aperture is used for detecting the aperture. A scheme I of the invention is that a first not-go end, a first clearance end and a first through end on a first detecting tool unit are arranged in turn along an axis; a marking end is arranged on an end surface of the first through end or the first not-go end; the first through end, the first not-go end, the first clearance end and the marking end are integrally made; an external diameter of the marking end is less than that of the first through end; and the first detecting tool unit is provided with a through hole along the axis. A scheme II of the invention is that a second through end, a second clearance end, a second not-go end and a holding end on a second detecting tool unit are arranged in turn along an axis and integrally made; an external diameter of the holding end is less than that of the second through end; and a blind hole is arranged on an end surface of the second through end. The detecting tool of the invention is used for detecting the aperture.
Description
Technical field
The present invention relates to a kind of survey instrument, be specifically related to a kind of feeler gauge that is used for detection aperture.
Background technology
The feeler gauge of existing detection aperture is formed by go side A, not-go-end B and rod member C, see Fig. 7, go side and not-go-end are separately positioned on the two ends of rod member, the go side is the lower deviation in aperture, and not-go-end is the upper deviation in aperture, when detection aperture, if the aperture can be passed through in the go side, and not-go-end can not pass through the aperture, and then this aperture is qualified, and promptly this aperture is in margin tolerance; If the aperture can be passed through in the go side, and not-go-end also can pass through the aperture, then this aperture is underproof, and promptly this aperture is not in margin tolerance; The deficiencies in the prior art part is: it (is that the aperture is filled in once in the go side that (1), a hole will be detected twice, not-go-end is filled in the aperture once), make that detection is loaded down with trivial details, expend a large amount of detection man-hours, detect man-hour in order to reduce, not to detect before the part warehouse-in by part, but sampling observation, thereby part rejection rate height caused; (2), a kind of aperture of specification need join a feeler gauge, interchangeability is poor.
Summary of the invention
The objective of the invention is for the feeler gauge that solves existing detection aperture when the detection aperture, a hole will detect twice, expends and detects man-hour, causes can not pursue part before the part warehouse-in and detect, and causes the high problem of part rejection rate, and a kind of testing tool of hole is provided.
The solution of the present invention one: described testing tool comprises at least one first testing tool unit, the first testing tool unit comprises first go side, first not-go-end, first empty cutter end and the mark end, first not-go-end, the first empty cutter end and first go side set gradually along axis, the mark end is arranged on the end of first go side or first not-go-end, first go side, first not-go-end, the first empty cutter end and mark end are made one, the external diameter of mark end is less than the external diameter of first go side, and the described first testing tool unit is provided with through hole along axis.
The solution of the present invention two: described testing tool comprises at least one second testing tool unit, the second testing tool unit comprises second go side, second not-go-end, the second empty cutter end and controls end, second go side, the second empty cutter end, second not-go-end and control end and set gradually along axis, second go side, the second empty cutter end, second not-go-end and control end and make one, control the external diameter of the external diameter of end less than second go side, the end face of described second go side is provided with blind hole.
The present invention has following beneficial effect: one, the present invention utilizes go side and not-go-end once to finish the detection in a hole of part, a feeler gauge need be joined in a kind of aperture of specification, reduce detection man-hour, before the part warehouse-in, can pursue part and detect, reduced the part rejection rate.Two, the present invention can be according to the needs arbitrary combination of detection aperture, and a testing tool can detect the different aperture of multiple size respectively, and is easy to use, easy.Three, the present invention can improve the quality and the speed of each plant-manufactured machine parts, improves the commutative rate and the interworking rate of part, can reduce the phenomenon of burning bearing.Four, the present invention detects easily, and anyone can be convenient to use.
