Not-go-end is equipped with the second annular groove for concaving towards regulator central axes with regulator joint；
The slot bottom of the first annular groove includes the flat segments and bevel phase to connect, and the bevel phase is located remotely from regulator
One end, the angle with horizontal plane is 10 °, a diameter of first annular groove of the corresponding first annular groove of the flat segments
Maximum gauge, and the diameter of the corresponding first annular groove of bevel phase is less than the maximum gauge of first annular groove, described the
The diameter of second ring groove is more than the maximum gauge of first annular groove.
Further, the lower limiting value phase of the maximum gauge of the first annular groove and tested float grease seal slot tolerance
Deng the diameter of the second annular groove is equal with the tested upper limit value of float grease seal slot tolerance.
Further, the length of the flat segments is the 0.38- of the slot bottom projected length in the horizontal direction of first annular groove
0.42 times.
Further, the cavity is equipped with intermediate incline with regulator joint.
Further, the angle of the intermediate incline and horizontal plane is 30 °.
The utility model has the beneficial effects that：
First annular groove and second annular groove is respectively set at the both ends of regulator, with embedded tested float grease seal slot
It is interior, wherein the maximum gauge of first annular groove is equal with the tested lower limiting value of float grease seal slot tolerance, and the second annular is recessed
The diameter of slot is equal with the tested upper limit value of float grease seal slot tolerance, need to only be embedded in regulator and be detected in float grease seal slot i.e.
It can check whether qualification, simple in structure, simple operation, checkability is high, meanwhile, intermediate incline guides regulator insertion is tested to float
In oil seal groove, embedded resistance is reduced.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the schematic diagram that go-no go gauge insertion is detected inside float grease seal slot；
Fig. 3 is that go-no go gauge is detached from the schematic diagram for being detected float grease seal slot.
In attached drawing：1- regulators, the go sides 2-, 3- not-go-end, 4- cavitys, 5- first annular grooves, 6- second annular grooves, 7- are flat

Specific implementation mode
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
Other similar embodiments that logical technical staff is obtained without making creative work, should all belong to the application
The range of protection.In addition, the direction word mentioned in following embodiment, such as "upper" "lower" " left side " " right side " etc. are only refer to the attached drawing
Direction, therefore, the direction word used is for illustrative and not limiting the invention.
The utility model is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
Embodiment one：
As shown in Figs. 1-3, a kind of float grease seal slot go-no go gauge, including regulator 1, the regulator 1 is in the internal circle for cavity
Column, one end are set as go side 2, and the other end is not-go-end 3, and the go side 2 is equipped with 1 joint of regulator and concaves towards 1 axis of regulator
The first annular groove 5 of line, the not-go-end 3 are equipped with the second annular groove 6 for concaving towards 1 central axes of regulator with 1 joint of regulator.Quilt
It examines workpiece 10 and is equipped with tested float grease seal slot 11, first annular groove 5 and second annular groove 6 for the embedded tested oil that floats
Sealing groove 11, to examine tested float grease seal slot 11 whether qualified.
The slot bottom of the first annular groove 5 includes the flat segments 7 to connect and bevel phase 8, and the length of the flat segments 7 is
0.38-0.42 times of the slot bottom of first annular groove 5 projected length in the horizontal direction, the bevel phase 8 is located remotely from regulator 1
One end, the angle with horizontal plane are 10 °, a diameter of first annular groove of 7 corresponding first annular groove 5 of the flat segments
5 maximum gauge, and the diameter of 8 corresponding first annular groove 5 of bevel phase is less than the maximum gauge of first annular groove 5, together
