Abstract
The utility model relates to a dial gauge style instrument for taper measurement, which achieves the purpose of taper measurement mainly through changing the angular measurement into the measurement of length. The utility model is mainly composed of a test rod, a test sleeve, a spring and dial gauge.
Description
The utility model relates to the instrument of coning angle in a kind of novel measurement, and it mainly is to measuring the improvement of inner cone angle instrument.It is to change into measurement of length by the measurement with angle to achieve the goal.This inner cone angel measuring instrument mainly is made up of test rod, detection cover, spring and dial gauge etc.
At present, in mechanical processing industry, the product of coning angle in known is adopted coning angle in the standard taper feeler gauge measured hole usually.When the part of coning angle in unknown is surveyed and drawn, adopt the method for cutting measurement open usually.The previous case is because production standard feeler gauge technology is loaded down with trivial details, the cycle is long, expense is high, and for typical products in mass production, it is more suitable to adopt this method to measure.But in batches little, the duration is tight or the diverse product of interior coning angle adopts the standard feeler gauge just economical inadequately.Latter event is owing to need cut measurement open and not only waste time and energy but also destroyed former part.
The purpose of this utility model provides a kind of novel inner cone angel measuring instrument with regard to being to avoid above-mentioned weak point.It can measure interior coning angle accurately, rapidly.It mainly is made up of test rod, detection cover, spring and dial gauge.Its major technique characteristics are that test rod 1 can be free to slide in detecting cover 2 under guider screw 6 controls, and dial gauge 9 is locked at by lock-screw 8 and detects cover 2 tops, and the contact outside of dial gauge 9 is with spring 7 contacts and contacts with the bottom of test rod 9.Pressing plate 4 is tightened on the detection cover 2 by tightening screw 13, and there are two movably housing screws 5 on pressing plate 4 both sides.
Accompanying drawing 1 is schematic appearance of the present utility model.
Accompanying drawing 2 is diagrammatic cross-section of the present utility model.1-----test rod 2-----detection cover 3-----fixed pin 4-----pressing plate 5-----housing screw 6-----guider screw 7-----spring 8-----lock-screw 9-----dial gauge 10----lock sleeve 11----spring press-cover 12---tightens screw 13-----and tightens screw
Below in conjunction with drawings and Examples in detail design feature of the present utility model is described in detail.
In actual design with in making, deviser of the present utility model according to interior coning angle equal on the same circular cone distance between the vary in diameter amount and diameter change than 1/2nd, i.e. formula S=tg (a/2)=(D-d)/2L.If (D-d)/2 be constant C, then S=tg (a/2)=C/L.As long as therefore measuring L just can determine taper value S.When making measuring instrument, allow 1/2nd of test rod 1 and detection cover 2 head diameter differences be constant, be assumed to 1mm.Be C=(D-d) 2=1.Selected range is the dial gauge of some greatly.Earlier at grade, tighten screw 12 before measuring the head end adjustment of test rod 1 and detection cover 2.Adjust dial gauge 9 and give an one precompressed amount.Test rod 1 with detect cover 2 and put into institute and surveys on the workpiece workpiece inner conical surface, make the interior hole end surface of pressing plate 4 and workpiece after putting down, tighten screw 13 during measurement.Regulate fixed pin 3 and allow its stretching endoporus, tighten screw 5.Unclamp lock-screw 12.Test rod 1 moves under the promotion of spring 7, and the bar head contacts with another point of workpiece inner conical surface.Read relative shift L by dial gauge 9, be assumed to 1mm, C=1, L=1 substitution formula S=tg (a/2)=CL.Draw S=1, a/2=45 degree, a=90 degree.Therefore coning angle is 90 degree in the workpiece.
The utility model is reasonable in design, and is easy to use, directly perceived, accurate, the life-span is long, applied widely.Can not only measure the workpiece process of known inner cone tapering, can also measure the workpiece of unknown inner cone tapering.Has very big promotional value.
