Description
Technical field
The utility model belongs to testing tool and manufactures and designs the field, especially belongs to a kind of tapering instruments of inspection.
Background technology
At present, taper fit cooperates closely with it, and more easily detachable characteristics are widely used in mechanical industry; Especially in the heavy-duty machinery industry, but taper fit is when bad, and, tapering contact rate excessive like taper error is low etc.; To cause the cooperation premature damage, be unfavorable for permanent use.So tapering checks the link of checking in manufacture process, to seem particularly important.
Detect for big tapering, generally take vernier caliper and bevel protractor to cooperate the inspection tapering, but this check system error is bigger, not accurate enough, causes quality control power relatively poor, the acceptable quality poor stability.
Summary of the invention
The utility model discloses a kind of tapering instruments of inspection, the problem that the utility model will solve provides a kind of in actual production processing, detects the instrument of processing work tapering through the standard comparative approach.
The utility model through following be exactly that scheme realizes:
The tapering instruments of inspection is made up of a connecting rod, stiff end and movable end, it is characterized in that: said stiff end by the tapering piece and fixedly cushion block constitute, fixedly cushion block is fixed on connecting rod one end, the tapering piece is fixed on fixedly on the cushion block; Said movable end is made up of sleeve, holding screw, dial indicators rack, clock gauge and movable cushion block, and movable cushion block is fixed on the sleeve, and the dial indicators rack that connects clock gauge is fixed on sleeve, and sleeve slides on connecting rod and can fix through holding screw.
Further said fixedly cushion block and movable cushion block upper surface line and pitman shaft line parallel.
Preferred said tapering piece two sides are and have the tapering inclined-plane.
Preferred said dial indicators rack is a cylinder, and cylinder has the through hole that inserts clock gauge and the fixing bolt of clock gauge.
The preferred said tapering instruments of inspection has two groups of clock gauges at least.
Said connecting rod xsect is rectangle or polygon, and preferred connecting rod xsect is a rectangle.
The utility model check system mainly is to detect through comparing with the standard taper mould.Need instrument to comprise the tapering mould and the above-mentioned tapering instruments of inspection during check, the tapering mould comprises outer prod cast and interior prod cast, and two tapering mould cooperations are very good, the standard taper that uses when this tapering mould is checked as tapering.
The said tapering instruments of inspection is made up of stiff end, movable end and connecting rod.Stiff end is fixed on connecting rod one end, by one fixedly tapering piece and cushion block constitute, the fixedly tapering piece both sides of stiff end all have tapering, with outer prod cast and interior prod cast all can good fit.Movable end is made up of sleeve, holding screw, dial indicators rack, clock gauge, cushion block.Wherein, dial indicators rack is fixed on the sleeve, and two unthreaded holes and two countersunk head threaded holes are arranged on the support, and unthreaded hole is used to penetrate clock gauge, and the countersunk head threaded hole is used for the tightening clock gauge.Jacket casing is on connecting rod, and sleeve can be free to slide on connecting rod, on two groups of holding screws are arranged, behind the two groups of holding screws of screwing, sleeve will be fixed on connecting rod.Clock gauge is inserted in the unthreaded hole on the dial indicators rack, inserts threaded hole with screw from countersunk head one side, can clamp clock gauge.The quantity of clock gauge is relevant with the length of measuring tapering, but minimumly must not be lower than two.
During use, earlier the holding screw on the sleeve is unclamped, so that movable end can be free to slide on connecting rod.Measuring external taper with inner cone is example; Earlier the stiff end of the said tapering instruments of inspection is leaned against a side of interior prod cast; Let the cushion block of stiff end and movable end be fitted on the end face of interior prod cast, movable end adjustment sleeve is earlier adjusted the clock gauge position then to the approximate location of clock gauge effect; When clock gauge produces certain reading, clock gauge is clamped, write down the clock gauge reading.
The tapering instruments of inspection is taken out from prod cast, with the tapering of this cubing examining workpieces of adjusting.Stiff end is stuck in a side of tapering to be checked; Movable end is stuck in the opposite side of tapering to be checked, lets active side backing plate and fixation side backing plate fit on the end face of tapering to be checked, writes down the clock gauge reading; If the clock gauge reading departs from allowed limits; Proving that then this tapering is qualified, if deviation is overproof, then is rejected part.
When detecting outer cone, only need movable end is turned around to pack into, prod cast is that master die is measured in addition, and measuring method is consistent with the inner cone measuring method.
This tapering instruments of inspection is compared prior art and is had the following advantages:
1, taper measurement is accurate;
2, use the different tapers mould instead, can detect the tapering of different-diameter;
3, interior outer cone cooperation all can be checked, and has improved the interchangeability that awl is joined.
