The utility model is realized through following technical scheme: design, a kind of groove chi of manufacturing; Comprise a chi shape main body; Said chi shape main body is provided with pipe end groove measuring head; Said pipe end groove measuring head is made up of measurement of angle head and linear measure longimetry head, and said measurement of angle head and said linear measure longimetry head are installed in the same end of said chi shape main body.
As the further improvement of the utility model, said measurement of angle head rotates around the end of said chi shape main body; Said measurement of angle head is provided with the angular readings unit.
As the further improvement of the utility model, said linear measure longimetry headgear is being fixed on the said chi shape main body on the said chi shape main body and through fastening unit.
As the further improvement of the utility model, said chi shape main body is provided with the length read counting unit; Said length read counting unit reads the length of the root face of tube groove.
As the further improvement of the utility model, said linear measure longimetry head is provided with the length read counting unit; Said length read counting unit reads the length of the root face of tube groove.
As the further improvement of the utility model, said linear measure longimetry head moves up and down along the direction of said chi shape main body; One side of said linear measure longimetry head forms the angle of groove perpendicular to said chi shape main body and with the corresponding edge of said measurement of angle head.
As the further improvement of the utility model, said angular readings unit is scale mark, electronics indicator gauge or pointer indicator gauge.
As the further improvement of the utility model, said length read counting unit is scale mark, electronics indicator gauge or pointer indicator gauge.
The beneficial effect of the utility model is: through root face and the angle value that obtains pipeline simultaneously, improved the efficiency of measurement of tube groove greatly and reduced measuring error.
Description of drawings
Fig. 1 is the structural representation of the utility model groove chi.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further to describe.
A kind of groove chi; Comprise a chi shape main body; Said chi shape main body is provided with pipe end groove measuring head, and said pipe end groove measuring head is made up of measurement of angle head and linear measure longimetry head, and said measurement of angle head and said linear measure longimetry head are installed in the same end of said chi shape main body.
Said measurement of angle head rotates around the end of said chi shape main body; Said measurement of angle head is provided with the angular readings unit.
Said linear measure longimetry headgear is being fixed on the said chi shape main body on the said chi shape main body and through fastening unit.
Said chi shape main body is provided with the length read counting unit; Said length read counting unit reads the length of the root face of tube groove.
Said linear measure longimetry head is provided with the length read counting unit; Said length read counting unit reads the length of the root face of tube groove.
Said linear measure longimetry head moves up and down along the direction of said chi shape main body; One side of said linear measure longimetry head forms the angle of groove perpendicular to said chi shape main body and with the scallop of said measurement of angle head.
Said angular readings unit is scale mark, electronics indicator gauge or pointer indicator gauge.
Said length read counting unit is scale mark, electronics indicator gauge or pointer indicator gauge.
In one embodiment; As shown in Figure 1; A kind of groove chi comprises a chi shape main body 1, and said chi shape main body 1 is provided with pipe end groove measuring head; Said pipe end groove measuring head is made up of measurement of angle 2 and linear measure longimetry 3, and said measurement of angle 2 and said linear measure longimetry 3 is installed in the same end of said chi shape main body 1.Generally speaking, the reading of groove generally is divided into two, the data of angle and root face.
Said measurement of angle 2 end around said chi shape main body 1 rotate; Said measurement of angle 2 is provided with the angular readings unit, among the embodiment in, this measurement of angle head with turning axle 21 be the center can about be rotated, the angle of rotation can be adjusted arbitrarily, is between 0 ~ 60 like the anglec of rotation among the embodiment.
Said linear measure longimetry 3 is enclosed within on the said chi shape main body 1 and through fastening unit and is fixed on the said chi shape main body 1, and fastening unit generally adopts lower-cost devices such as nut, screw, adopts nut 31 in the present embodiment.
Said chi shape main body 1 is provided with the length read counting unit; Said length read counting unit reads the length of the root face of tube groove, and the length read counting unit is scale mark, electronics indicator gauge or pointer indicator gauge, and in the present embodiment, this length read counting unit is a length scale mark 33.
Certainly, the reading of root face also can be realized through the length read counting unit is arranged on the linear measure longimetry head.Be that said linear measure longimetry head is provided with the length read counting unit; Said length read counting unit reads the length of the root face of tube groove.
Said linear measure longimetry 3 direction along said chi shape main body move up and down; One side 32 of said linear measure longimetry 3 forms the angle of grooves perpendicular to said chi shape main body 1 and with the corresponding edge 22 of said measurement of angle 2.
During measurement, block the root face of tube groove with the linear measure longimetry head, at this moment, sliding length measuring head slowly makes the root face and the linear measure longimetry head chucking of groove, at this moment, tightens nut, and the linear measure longimetry head is fixed on the chi shape main body, just can read the length of root face.When the linear measure longimetry epicranium tightened, the rotation angle measurement head was close on the groove of pipeline the limit 22 of measurement of angle head, just can read the angle of groove.At this moment, the limit 32 of linear measure longimetry head and the limit 22 of measurement of angle head are close to respectively on the groove, so just can obtain the angle value and the length value of groove simultaneously, have improved measuring accuracy and efficient.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
