Abstract
The invention relates to a sphere accuracy detecting device. The sphere accuracy detecting device comprises a locating barrel, a through hole is arranged at the center of the locating barrel, a detecting meter is inserted into the through hole, an inner threaded hole is mounted on the outer circle of the locating barrel, a locating screw is installed in the inner threaded hole, and a semisphere groove is disposed at the center of the bottom end face of the locating barrel. The sphere accuracy detecting device has the advantages of being simple in structure, easy and convenient to operate and high in reliability and detecting accuracy.
Description
Technical field
The present invention relates to the cubing technical field, relate in particular to a kind of pick-up unit to workpiece sphere end sphere precision.
Background technology
Field of machining, detection for Workpiece Machining Accuracy generally all has special-purpose cubing, such as interior or external diameter that can measuring workpieces by vernier caliper, whether the length equidimension meets the requirements, but for the workpiece with domed ends, if detect the machining precision of its domed ends, if the general measurers such as use vernier caliper can not be satisfied the demand.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, a kind of sphere accuracy detecting device is provided, it is simple in structure, and is easy and simple to handle, and reliability and detection degree of accuracy are high.
The technical solution adopted in the present invention is as follows:
The sphere accuracy detecting device comprises positioning tube, and the center of positioning tube is inserted in the through hole and detected table with through hole; The cylindrical of positioning tube is equipped with dog screw with internal thread hole in the described internal thread hole; The bottom face center of positioning tube is with hemispherical groove.
The invention has the advantages that: on the positioning tube with central through hole, insert in the central through hole and detect table, on the cylindrical of positioning tube dog screw is installed, can clamp detecting the table location, on the bottom face of positioning tube with hemispherical groove, the sphere end of workpiece is put into hemispherical groove, workpiece is swung the different parts that makes workpiece sphere end and contacts with detection table table point, detects the machining precision of workpiece sphere end; The present invention is simple in structure, and is easy and simple to handle, and reliability and detection degree of accuracy are high.
Description of drawings
Fig. 1, Fig. 2 are use constitutional diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the present invention includes positioning tube 1, the center of positioning tube 1 is with through hole 11, and through hole 11 interior insertions detect table 2; The cylindrical of positioning tube 1 is equipped with dog screw 3 with internal thread hole in the described internal thread hole, the table bar 21 that inserts the detection table 2 in the through hole 11 is positioned anchor clamps; The bottom face center of positioning tube 1 is with hemispherical groove, the domed ends of workpiece 4 is put into described hemispherical groove, make the inwall close contact of workpiece 4 and described hemispherical groove, allow simultaneously the table point 22 of detection table 2 and the sphere-contact of the domed ends of workpiece 4, the domed ends of workpiece 4 is swung in the hemispherical groove of positioning tube 1, the table point 22 of detection table 2 is contacted with the different parts of the sphere of the domed ends of workpiece 4, if the pointer of detection table 2 does not deflect or deflection angle in claimed range, whether the sphere machining precision of domed ends that then can judge workpiece 4 is satisfactory, otherwise, then undesirable.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
