Description
Technical field
The utility model belongs to parts detection technique field, is specifically related to the aid for detecting machined surface flatness.
Background technology
The flatness detecting parts machining face is one of quality testing department routine inspection project, and the height of parts machining facial plane degree directly affects assembly quality and the reliability of complete machine.At present conventional detection method is that the height gauge re-using band digital display function is measured first by placing part marble countertop after calibration.The drawback of the method is: the face machining precision that part contacts with marble countertop can not ensure, directly affects the follow-up measurement of part processing plane degree, causes the resultant error of measurement comparatively large, well can not ensure the precision that the part later stage assembles and reliability.
Utility model content
In order to solve, the measuring result error that existing part machined surface flatness detection mode exists is large, later stage assembly precision and the lower defect of reliability, and the utility model devises the aid for detecting machined surface flatness.
For detecting the aid of machined surface flatness, comprise pedestal 1, push rod 2;
Described pedestal 1, in upright cylindric, is axially arranged with through hole 11 in the middle part of it; On pedestal 1 bottom, to be provided with bolt hole, bolt hole and through hole 11 through for radial direction, and described bolt hole inside spin is combined with dogbolt 4;
Described push rod 2 is straight-bar, the top of push rod 2 is top 21 of taper, the push rod 2 segment body periphery of top less than 21 is provided with external thread, and threaded engagement has the adjustment seat 3 of ring-type on the external thread of push rod 2: the footpath, bottom of described push rod 2 has concaved locking groove 5;
Push rod 2 is vertically plugged in the through hole 11 of pedestal 1, and the adjustment seat 3 on push rod 2 external thread contacts with the bottom surface of pedestal 1, and the dogbolt 4 bottom pedestal 1 puts in the locking groove 5 of push rod 2, by the axial location moving radially, realize push rod 2 of dogbolt 4.
The cone angle of described top 21 shaft sections is 45 °.
Described push rod 2 is clearance fit with coordinating of through hole 11 on pedestal 1.
Advantageous Effects of the present utility model:
(1), when detecting part, uses three aids to support part, rotate adjusting seat and drive push rod to make part machined surface correspondence 3 of aid be on sustained height, lock push rod by dogbolt; Three-point shape on the part that aid is corresponding becomes a reference field, and by machined surface, other is put reference field therewith and compares, and tests out the flatness of part; The utility model structure is simple, easy to adjust, quick to push rod position, improves precision and the reliability of the assembling of part later stage, improves the work efficiency detecting parts flatness.
(2), the utility model is provided with dogbolt in the bottom of pedestal, after parts are adjusted to desired height, on pedestal with dogbolt by the effect of push rod bottom locking groove, the axial location realizing push rod, parts are stabilized in required height, easy and simple to handle, popularization degree is high.
(3), the utility model by the top cone angle being designed to 45 ° of push rod, any part of work piece can be supported, make support convenient.
