It is slidably connected with sliding slot 22；Slide rule 21 is equipped with graduated scale 23, and sliding slot 22 is equipped with large aperture margin of tolerance scale 24 and aperture
Diameter margin of tolerance scale 26；Slide rule 21 and 22 one end of sliding slot are equipped with card base 25, and card base 25 is symmetrical outer on slide rule 21 and sliding slot 22
It stretches；Two-stage step is equipped with below card base 25, top bar is datum level A when detecting special-shaped stepped hole small-bore；Getting out of a predicament or an embarrassing situation is inspection
Survey datum level B when special-shaped stepped hole large aperture.
The above-mentioned apparatus of the utility model is used to carry out the method for rapid survey abnormal shape stepped hole as with reference to such as Fig. 6, the party
Method is detected using the Angular Dimension of 10 pairs of homemade gauge block fan-shaped boss 3；By the scalloped recess 12 on gauge block 10 when detection
It is directed at fan-shaped boss 3 and fills in special-shaped stepped hole 2, can fill in, indicate that fan-shaped 3 Angular Dimension of boss is qualified, can not fill in, indicate
The Angular Dimension of fan-shaped boss 3 is unqualified.Homemade gauge block 10 and slide calliper rule 20 detect small-bore 4；By gauge block when detection
Scalloped recess 12 on 10 is directed at fan-shaped boss 3 and fills in special-shaped stepped hole 2, and makes 11 side of rectangle annular groove and fan on gauge block 10
3 end face of shape boss pushes against；The card base 25 for first shrinking slide calliper rule 20 passes through 10 inner hole of gauge block, by the datum level A of slide calliper rule 20 and gauge block 10
Datum level C fitting, then expanding outwardly slide rule 21 again contacts two card bases 25 of slide calliper rule 20 with 4 inner wall of small-bore, measures different
4 size of small-bore of type stepped hole 2；The size jerk value that slide calliper rule 20 obtain small-bore 4 is rotated horizontally again.Measure 4 ruler of small-bore
When very little and size jerk value, 0 of observation graduated scale 23 is qualified in small-bore margin of tolerance scale 26；It otherwise is not conform to
Lattice, in unqualified situation, 0 of graduated scale 23 reads measured value at small-bore 26 left side of margin of tolerance scale, is convenient for workpiece
It reprocesses, until qualified；0 of graduated scale 23 directly scraps at small-bore 26 right side of margin of tolerance scale.
Large aperture 5 is detected using homemade gauge block 10 and slide calliper rule 20；As shown in fig. 6, will be on gauge block 10 when detection
Scalloped recess 12 be directed at fan-shaped boss 3 and fill in special-shaped stepped hole 2, and keep 11 side of rectangle annular groove on gauge block 10 and sector convex
3 end face of platform pushes against；The card base 25 for first shrinking slide calliper rule 20 passes through 10 inner hole of gauge block, by the base of the datum level B of slide calliper rule 20 and gauge block 10
Quasi- face C fitting, then expanding outwardly slide rule 21 again contacts two card bases 25 of slide calliper rule 20 with 5 inner wall of large aperture, measures special-shaped platform
5 size of large aperture in rank hole 2；The size jerk value that slide calliper rule 20 obtain large aperture 5 is rotated horizontally again.Measure 5 size of large aperture and
When size jerk value, 0 of observation graduated scale 23 is qualified in large aperture margin of tolerance scale 24；Otherwise to be unqualified, no
Under Qualification, 0 of graduated scale 23 reads measured value, reprocesses convenient for workpiece at large aperture 24 left side of margin of tolerance scale,
Until qualified；0 of graduated scale 23 directly scraps at large aperture 24 right side of margin of tolerance scale.
Embodiment
This example special-shaped stepped hole to be measured is as depicted in figs. 1 and 2.Fig. 1 is the schematic diagram from the outside of round tube 1；Fig. 2 is round
The schematic diagram observed on the outside of pipe；From Fig. 1 and Fig. 2.Special-shaped stepped hole is located at 1 side of round tube, is small on the outside of special-shaped stepped hole 2
4 sections of aperture is 5 sections of large aperture on the inside of special-shaped stepped hole 2, is equipped with three sections of fan-shaped boss 3 for 4 sections in small-bore.In special-shaped stepped hole 2
Fan-shaped boss 3 play a part of in the product switch limit, large aperture 5 and the concentricity of large aperture 4 play a crucial role to sealing.
Therefore particularly important to product quality to the inspection of special-shaped stepped hole.The method of existing detection inner hole mainly uses inside caliper, and thousand
Divide ruler measurement.It but is small-bore on the outside of stepped hole due to there is fan-shaped boss inside the abnormal shape stepped hole, inside is large aperture, existing
Some inside calipers, micrometer are unable to satisfy this hole measurement requirement.Only have lathe itself precision to guarantee working special-shaped at present
The mismachining tolerance in rank hole, product quality not can guarantee.The device and method for the rapid survey abnormal shape stepped hole that this example provides can have
Effect solves above-mentioned technical problem.
The device of this example gauge block 10, slide calliper rule 20 as shown in fig. 6, be made of.It is recessed that 10 1 end face of gauge block is provided with symmetrical rectangle
Slot 13 is equipped with two-stage step below the card base 25 of slide calliper rule 20, this two-stage step is used for can be quick on gauge block 10 when measuring
Precise measurement is convenient in positioning.Gauge block 10 is put into special-shaped stepped hole 2, for measuring the position dimension of fan-shaped boss 3.Slide calliper rule 20
It is placed in gauge block 10, the two-stage step on slide calliper rule 20, it is specific to measure for measuring the big small pore size on special-shaped stepped hole 2
It is as follows: one, the A datum level of slide calliper rule 10 to be placed on the C datum level of gauge block 10, slide calliper rule 20 are rotated, if 20 0 groove of slide calliper rule is small
Between hole tolerance range scale 26, then can quickly determine that small-bore 4 is qualified, as if it is not, if for unqualified, unqualified situation
Under, 20 0 groove of slide calliper rule at small-bore 26 left side of margin of tolerance scale, reprocess convenient for workpiece, directly by the true readout value of slide calliper rule
To qualification, directly scrapped at small-bore 26 right side of margin of tolerance scale；Two, the B datum level of slide calliper rule 10 is placed in the C of gauge block 10
On datum level, slide calliper rule 20 are rotated, if 20 0 groove of slide calliper rule can quickly determine macropore between large aperture margin of tolerance scale 24
Diameter 5 is qualified, as if it is not, if be it is unqualified, in unqualified situation, 20 0 groove of slide calliper rule is on 24 left side of large aperture margin of tolerance scale
When side, the true readout value of slide calliper rule is reprocessed convenient for workpiece, until it is qualified, it is direct at large aperture 24 right side of margin of tolerance scale
It scraps.
The device of the utility model quickly can accurately measure whether product meets production matching requirements, largely
Product time of measuring is improved, measurement accuracy is improved, is improved the Product Assembly period, meanwhile, the device, the operation is simple and flexible.
