Abstract
The utility model relates to the field of gear detection, in particular to a device for inspecting a spindle of a gear. Two ends of the spindle are respectively sheathed with an expansion sleeve; an inner hole of the expansion sleeve is a cone surface which is contacted with a cone surface of the spindle; and the outer edges of the expansion sleeves at the two ends of the spindle are respectively provided with a compression nut. By adopting the technical scheme, the cone surface of the spindle is added with the expansion sleeve, when a part is assembled, the compression nuts are respectively used for pushing and pressing the expansion sleeves, so that a centering surface of the expansion sleeve is contacted with a centering hole of the part in a seamless way at two positions which have a certain distance in the axial direction, and the functions of detecting and centering are finished with stable centering, therefore, the problem that the instable axial centering of the part has influence on the detection effect of the positional precision is solved, and false detection and false judgment are reduced.
Description
Technical field
The utility model relates to the gear detection range, is a kind of gear test mandrel device.
Background technology
Gear test mandrel is the important auxiliary of gear pick-up unit.During detection of gear, no matter be circular hole or splined hole, often adopt the tapering centering mandrel, hold the positional precision inspection that product is made the gear part region of interest with dress, limited by the tapering face of mandrel, it is inadequate that part dress is held centering, and an end of hole in piece part is with after the tapering face contacts, and there is the gap in the other end, influenced the stability that the part dress is held like this, it is big easily to cause the testing result scattered error, influences product quality and judges conclusion, brings harmful effect for the manufacturing of product and quality control and checking and accepting.In addition, for adapting to the manufacturing tolerance requirement in part centering aperture,, to prepare the tapering mandrel that many fragment size require with the kind part to satisfy the check needs.
Summary of the invention
The purpose of this utility model is that a kind of new technical scheme will be provided.
The utility model is achieved in that at the two ends of mandrel and is with the expanding cover respectively that the endoporus of expanding cover is the conical surface, contacts with the conical surface of mandrel, in the outer of the two ends of mandrel expanding cover gland nut is housed respectively.
Owing to adopted technique scheme, the conical surface of mandrel is added with the expanding cover, behind the encapsulation part, push the expanding cover respectively with gland nut, the centering face of expanding cover is contacted as zero-clearance on position, axial certain distance two place with the part internal point, finish the detection centering function, it is more stable to feel relieved, so both solved because of part axial centering instability,, reduced the flase drop erroneous judgement again the influence of part position accuracy detection effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings: 1, mandrel; 2, expanding cover; 3, gland nut; 4, expanding cover; 5, gland nut.
Embodiment
The utility model is further described below in conjunction with drawings and Examples.
In Fig. 1, be with expanding cover 2 and expanding cover 3 respectively at the two ends of mandrel 1, the endoporus of expanding cover 2 and expanding cover 3 is the conical surface, contacts with the conical surface of mandrel 1, in the outer of the two ends of mandrel 1 expanding cover 2 and expanding cover 3 gland nut 3 and gland nut 5 is housed respectively.
