Description
Technical field
The present invention relates to a kind of verifying attachment, refer in particular to and use the scalable movable lever indicator bracket on a kind of test flat plate, be mainly used in the clamping lever dial gauge detects processing parts on test flat plate the depth of parallelism.
Background technology
The speed regulator flyball of diesel engine is a kind of special-shaped part; Profile is irregular, but between a plurality of size factor Geometrical Tolerance Principle such as the higher depth of parallelism and verticality is arranged, in each link of part manufacture process; Like head inspection, self check, patrol and examine, the inspection of intact preface, the inspection of dispatching from the factory etc. all will check continually; The size that has is sampling observation, and the size that has is full inspection, and the workload of check is very big.Though adopt the three-coordinates measuring machine accuracy of detection high, receive the restriction of fund and work-yard; Adopt conventional sense utensil such as magnet stand clamping lever dial gauge, though or height gauge directly measure feasiblely, inefficiency is not suitable for production in enormous quantities.
Summary of the invention
For form and position tolerances such as the depth of parallelism between a plurality of size factors of frequent detection flyball and verticality; The invention provides and use the scalable movable lever indicator bracket on a kind of test flat plate; When flyball places on the measuring seat on request; When measuring seat is placed on the test flat plate,, regulate coarse adjustment and micrometer adjusting screw (mother) with scalable movable lever indicator bracket clamping lever dial gauge of the present invention; The spheric probe of lever indicator is contacted with workpiece or length bar; On test flat plate, drag gauge stand, can know the height change in the face of test flat plate to be detected from the mobility scale of pointer on the lever indicator dial plate, through calculating the depth of parallelism and the verticality numerical value that can draw the relative dimensions that Geometrical Tolerance Principle is arranged each other.
If regular part such as flat-type; Can directly part be placed on the test flat plate; Regulate coarse adjustment and micrometer adjusting screw (mother); The spheric probe of lever indicator is contacted with workpiece, on test flat plate, drag the gauge stand of dial gauge, can directly read the depth of parallelism numerical value of detection faces basal plane from the lever indicator dial plate.
The technical solution adopted for the present invention to solve the technical problems is: use the scalable movable lever indicator bracket on a kind of test flat plate; Comprise a pedestal, be fixed with a lever gusset on the pedestal, the middle part of lever gusset is fixed in the cannelure of pedestal through the revolution pin; One bottom portion of lever gusset supports with a stage clip; The other end is processed with a threaded hole in vertical direction, screws in a set screw, the cannelure pig of screw bottom and pedestal; Down, up rotate expansion screw, can make the lever gusset around revolution pin in the cannelure of pedestal, do certain angle about revolution.
On the lever gusset, be fixed with cramp bar, the dial gauge fixed bar is fixed on the cramp bar through 2 collets that interlock, the first revolution screw and cramp bar set nut, 2 collets, and one is inserted in cramp bar, and another is inserted in the dial gauge fixed bar.When the cramp bar set nut is screwed, can not turn round each other between 2 collets that interlock, can not on cramp bar, do upper and lower moving, can not turn round around the axis of cramp bar, and the dial gauge fixed bar can not stretch in the hole of collet and turn round.Unclamp the cramp bar set nut, can do 360 ° of revolutions between 2 collets that interlock, make the dial gauge fixed bar point to the seized part surface with certain angle; Make the dial gauge fixed bar can on cramp bar, do upper and lower moving, with the adjustment height; And the dial gauge fixed bar can stretch in the hole of first collet, with the extension elongation of adjustment dial gauge fixed bar.
External part at the dial gauge fixed bar is designed with the lever indicator clamping device, comprises the 3rd collet, second revolution screw and the lever indicator set nut, is used for the clamping lever dial gauge; Unclamp the lever indicator set nut, can lever indicator be taken off.
During measurement; Set screw on the adjustment (adjusting) lever gusset makes the spheric probe of lever indicator be in the extreme higher position, then according to the seized part surface height at first downwards; Unclamp the cramp bar set nut; The height of coarse adjustment lever indicator and angle make the spheric probe of lever indicator exceed about the 0.5～3mm of seized part surface the cramp bar set nut of screwing.The spheric probe of lever indicator is placed the seized part surface; The set screw on the adjustment (adjusting) lever gusset upwards again; The spheric probe of lever indicator is pressed to about the 1～2mm of seized part surface, and the fine setting set screw, make the dial plate pointer to zero or whole scale.
Drag the gauge stand of dial gauge, can read the parallelism tolerance numerical value on corresponding or whole plane at 2, can calculate the depth of parallelism and verticality numerical value between the relative dimensions according to this numerical value from the hunting range of dial plate pointer.
Can know that from technique scheme accuracy of detection is only relevant with the precision of test flat plate, accuracy of detection is high.The design of whole dial framework and manufacturing accuracy require not high, and number of parts is few, and manufacturing cost is lower, can make in batches.Each processing stations that need detect side and check point all can be equipped with the dial framework of respective numbers; Can greatly make things convenient for, satisfy the usefulness of each item detection of operator and testing staff; Can shorten round, stand-by period when detecting part, enhance productivity, easy to detect, quick.And can be used directly in the depth of parallelism that detects regular part on the test flat plate, very convenient, practical.
