In field of machining, it is sometimes desirable to measure on a certain axial workpiece the groove of end face relative to the symmetry of a certain cylindrical of this axial workpiece. Traditional measuring method checks only by single symmetry gauge, but, owing to two symmetry gauges will have error accumulation, the needs of actual production therefore can not be met.
Utility model content
For problem above, this utility model provides a kind of notch symmetry gauge, it is possible to the groove of Parts Measurement is relative to the symmetry requirement of a certain cylindrical fast and accurately.
This utility model is implemented by the following technical programs:
A kind of notch symmetry gauge, combined by measuring gage and gauge body and be assembled together, wherein said measuring gage includes measurement portion and the caudal peduncle portion that one connects, described gauge body is disc structure, the interior circular hole playing positioning action it is provided with in the center of gauge body, a place on the external edge of gauge is provided with the groove playing guide effect, and described groove and the preparation gap, measurement portion on measuring gage are for detecting the symmetry relative to this part outer of the groove on tested axial workpiece.
The caudal peduncle portion of described measuring gage has annular knurl, it is therefore an objective to prevent from use procedure is skidded.
The caudal peduncle portion of described measuring gage is shaped with the flat of 6-10mm, as the index face of this marking.
The beneficial effects of the utility model: by using this notch symmetry gauge, can well check that the end face groove of same axial workpiece requires within 0.06mm relative to the symmetry of a certain cylindrical of this axial workpiece, decrease multiple single symmetry gauge and use the error propagation brought, shorten the detection time, it is possible to check the symmetry requirement relative to end face of the different cylindrical as required.

Detailed description of the invention
A kind of notch symmetry gauge, is combined by measuring gage 1 and gauge body 2 and is assembled together, and is used for the 7H11 notch detecting tested axial workpiece 7 symmetry relative to this axial workpiece �� 34h8 within 0.06mm.
As depicted in figs. 1 and 2, described measuring gage 1 includes measurement portion 3 and the caudal peduncle portion 4 that one connects.
1. measurement portion 3 is of a size of 6.9620 -0.005, will be used for measuring the symmetry relative to a certain cylindrical of the facing groove of this axial workpiece.
2. the calculating in measurement portion 3:
The size in measurement portion: dI=(DM-t+F1)0 -T1;
The abrasion size in measurement portion: dIw=DM-t+F1-(TI+WI);
Wherein DM is the maximum material size of detected part notch;
T is the form and position tolerance of element to be measured;
F1 is the basic tolerance in measurement portion;
TI is the dimensional tolerance in measurement portion;
WI is the permission wear extent in measurement portion.
3. caudal peduncle portion is constituted and is alternatively referred to as handgrip part, this caudal peduncle portion annular knurl, it is therefore an objective to prevent from skidding in use procedure, convenient uses; There are flat the 8 of 8mm at this place of caudal peduncle portion one, as the index face of marking; The hole of �� 3 is also had, in order to hang the purpose of placement in caudal peduncle portion.
4. material is CrWMn, and hardness is HRC58-65.
As it is shown on figure 3, described gauge body 2 is in disc structure, being provided with the interior circular hole 6 playing positioning action in the center of gauge body 2, the place on gauge body 2 outer is provided with the groove 5 playing guide effect.
1. gauge body groove guiding position is of a size of 6.962(and measuring gage matching part), this groove port relative to the symmetry of endoporus within 0.01mm; There is circular hole in position point �� 34 (this hole size is the excircle dimension that this axial workpiece requirement has symmetry requirement relative to groove) in this gauge body, it has 6 �� 10 lightening cores.
2. the calculating of position point:
The size of position point: DL=dM+TL 0;
The abrasion size of position point: DLw=dM+ (TL+WL);
Wherein: dM is the maximum material size of detected shaft parts;
TL is the dimensional tolerance of measuring point;
WL is the permission wear extent of measuring point;
3. lead position:
Guiding position is not more than Smin with preparation gap, measurement portion;
Wherein: Smin is the minimum clearance at insert type gage for measuring position guiding position.
4. material is CrWMn, and hardness is HRC58-65.
As shown in Figure 4, the using method of notch symmetry gauge, comprise the following steps:
1. by borehole jack in gauge body 2 on the cylindrical of tested axial workpiece 7, the end face of one side end face of gauge body 2 Yu tested axial workpiece 2 groove position is fitted tightly, it is ensured that the upper edge at the cylindrical of gauge body 2 and tested axial workpiece 7 groove position is in sustained height;
2. the groove 5 of gauge body 2 is corresponding with the groove position of tested axial workpiece 7;
3. by the groove 5 of the measurement portion 3 insertion regulator 2 of measuring gage 1, and successively measurement portion 3 is slidably reciprocated in the groove position of gauge body 2 and tested axial workpiece 7, then judge the groove detecting on tested axial workpiece 7 is relative to whether the symmetry of this part outer meets the requirements according to sliding condition, only when measurement portion 3 between the groove of gauge body 2 and tested axial workpiece 7 accessible by time, represent that the groove position of tested axial workpiece 7 meets the requirements relative to the symmetry of this part outer.
