Therefore, the structure is simple, the detection operation is convenient and quick, and the operation personnel can easily operate.
Description
Technical field
The utility model relates to the survey instrument of a kind of lower shaft right-hand member of flat seam machine casing to the symmetry of vertical pivot lower end.
Background technology
When the last axle of flat seam machine rotates, fixing conical gear drives the conical gear on the vertical pivot on it, the realization vertical pivot rotates, conical gear fixing on the subumbrella gear driven lower shaft of fixing on the vertical pivot rotates, and the rotation of lower shaft drives the rotating shuttle rotation that is fixed on the lower shaft, and realize the coordination of rotating shuttle and eedle, finally realize required sewing result.If but the symmetry of the lower shaft of finished product casing and vertical pivot is bad, will directly has influence on the engagement effect of vertical pivot lower gear and lower shaft gear, thereby cause the quality of the aspects such as the noise that shortens and have influence on machine serviceable life, moment of machine.The symmetry of this two axial ends of conventional sense generally is to adopt to go up axle, vertical pivot, shank, lower shaft length bar, adds isometry block, regulates supporting, and measurers such as height gauge, dial gauge, the right point of axle and lower shaft with reference to relevant table, is read symmetrical difference then in the leveling.Though the method can very accurately be read the difference of institute's inspection machine, detection speed is too slow, and loaded down with trivial details, and to the training that the operator also requires to have certain professional aspect, more is not suitable for full inspection in batches.
Summary of the invention
The utility model purpose provides the survey instrument of a kind of lower shaft right-hand member of flat seam machine casing to the symmetry of vertical pivot lower end, and it is simple in structure, and detecting operation is convenient and swift.
The technical solution of the utility model is: a kind of lower shaft right-hand member of flat seam machine casing is to the survey instrument of the symmetry of vertical pivot lower end, comprise first length bar, second length bar, measurer body, has measuring tank on the described measurer body, one end of described first length bar is the link that can link to each other with the right hole of the lower shaft of flat seam machine, the measuring junction of the other end for matching with described measuring tank; One end of described second length bar is the link that can link to each other with hole under the vertical pivot of flat seam machine, the measuring junction of the other end for matching with described measuring tank, the measuring junction of described first length bar, described second length bar all is inserted in the described measuring tank slidably, and the diameter of the measuring junction of the diameter of the measuring junction of described first length bar, described second length bar all equates with the width of described measuring tank.
The pressing plate that described measurer body comprises the measurer seat, is fixedly connected with described measurer seat, described measuring tank is arranged between described measurer seat and the described pressing plate.
Be fixedly connected with handle on the described measurer body.
The measuring junction of described first length bar, described second length bar is inserted in the described measuring tank simultaneously, and described first length bar is vertical mutually with the axial line of described second length bar.
Because the utilization of technique scheme, the utility model has following advantage compared with prior art: because the detection mode that has adopted first length bar, second length bar to match with measuring tank on the measurer body, so quickly and easily the lower shaft right-hand member of the flat seam machine casing symmetry to the vertical pivot lower end is detected in the scope of precision permission.

Embodiment
Referring to Fig. 1, Fig. 2, a kind of lower shaft right-hand member of flat seam machine casing is to the survey instrument of the symmetry of vertical pivot lower end, comprise first length bar 6, second length bar 7, measurer body 1, has measuring tank 5 on the described measurer body 1, one end of described first length bar 6 is the link that can link to each other with the right hole of the lower shaft of flat seam machine, the measuring junction of the other end for matching with described measuring tank 5; One end of described second length bar 7 is the link that can link to each other with hole under the vertical pivot of flat seam machine, the measuring junction of the other end for matching with described measuring tank 5, the measuring junction of described first length bar 6, described second length bar 7 all is inserted in the described measuring tank 5 slidably, and the diameter of the measuring junction of the diameter of the measuring junction of described first length bar 6, described second length bar 7 all equates with the width of described measuring tank 5.
The pressing plate 4 that described measurer body 1 comprises measurer seat 3, is fixedly connected with described measurer seat 3, described measuring tank 5 is arranged between described measurer seat 3 and the described pressing plate 4.
Be fixedly connected with handle 2 on the described measurer body 1.
The measuring junction of described first length bar 6, described second length bar 7 is inserted in the described measuring tank 5 simultaneously, and described first length bar 6 is vertical mutually with the axial line of described second length bar 7.
During operation: described pressing plate 4 by screw retention on described measurer seat 3, described handle 2 rotations are installed on the described measurer seat 3, the medial surface of the medial surface of described pressing plate 4 and described measurer seat 3 forms measuring tank 5, the width dimensions of described measuring tank 5 and first length bar 6, the external diameter of the measuring junction of second length bar 7 is identical, the upper limit difference of the width dimensions of described measuring tank 5 is the maximum tolerance of the symmetry of technological requirement, and first length bar 6, the external diameter tolerance of the measuring junction of second length bar 7 is zero substantially, first length bar 6, there is good cooperation requirement in the hole that the link of second length bar 7 is corresponding with it.During use, the link of first length bar 6, second length bar 7 is inserted in respectively under the right hole of lower shaft, the vertical pivot in the hole, remove the measuring junction of card first length bar 6, second length bar 7 then simultaneously with the measuring tank 5 of measurer body 1, if the measuring junction of two length bars can insert in the measuring tank 5 simultaneously like a cork, it is qualified just to judge, if can not enter simultaneously, then be judged to be defective.
Because adjustment and reading when this survey instrument need not be measured, thus convenient to operation, and because the simplicity of its operation and the simplicity of structure, it is also quite efficient and convenient that operating personnel learn left-hand seat.
