Drawings

Fig. 1 is the utility model discloses the bearing structure's for bearing sleeve inner circle run-out detection structure schematic diagram.

Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

The bearing sleeve inner circle run-out detection bearing structure shown in fig. 1 mainly comprises a base 1, a loading assembly 2 and the like.

The base 1 can be conventional, and only needs to support the loading component 2 and mount other measuring devices for detecting the inner circle runout; which has a slope facing the user so that the chassis 21 is mounted on the slope.

The material loading component 2 comprises a chassis 21 arranged on the base 1, a first groove 23 arranged on the chassis 21 and passing through the axial lead of the chassis, a second groove 24 arranged on the chassis 21 and vertical to the first groove 23, at least three outer limiting units 25 arranged at the end parts of the first groove 23 and the second groove 24, and four claw bars 26 arranged on the chassis 21 in a way of moving towards or away from each other; when the bearing sleeve is used, the bearing sleeve is directly sleeved on the four jaw strips and rotated manually, and the outer ends of the jaw strips 26 are contacted with the inner surface of the bearing sleeve to sense the roundness of the inner surface of the bearing sleeve (when the bearing sleeve is rotated manually, when the inner surface of the bearing sleeve is uneven, the jaw strips 26 can move relatively along with the concave-convex condition of the inner surface of the bearing sleeve).

In this embodiment, a plurality of through holes 22 are opened on the chassis 21, and the chassis 21 is detachably mounted on the base 1 by a plurality of fasteners (e.g. bolts) penetrating through the through holes 22. The three or four outer limiting units 25, specifically three outer limiting units, form an isosceles triangle, have the same distance with the axis of the chassis 21 (the specific distance can be determined according to the outer diameter of the bearing sleeve), and are used for accurately positioning the outer diameter of the bearing sleeve, so as to ensure that the outer diameter axis of the bearing sleeve does not deviate when the bearing sleeve rotates manually. Specifically, the bottoms of the first groove 23 and the second groove 24 are independently provided with a plurality of insertion holes arranged at intervals, the outer limiting unit 25 comprises a threaded rod 253 capable of being inserted into the insertion holes, a pressing block 251 sleeved on the threaded rod 253 and contacting with the chassis 21, and an adjusting nut 252 mounted on the threaded rod 253 and matched with the pressing block 251; the distance between the outer limiting unit 25 and the axial lead of the chassis 21 is adjusted by the jack.

In the present embodiment, the intersection of the first groove 23 and the second groove 24 is defined as a groove intersection point, and the groove intersection point is located on the axis of the chassis 21. Carry material subassembly 2 still including seting up in chassis 21 surface and extending the line through chassis 21 axial lead's storage tank (the slotted hole of waist shape usually), the bottom surface of jack catch strip 26 is equipped with storage tank matched with joint arch (the joint arch is less than the storage tank, thereby make jack catch strip 26 can be relative storage tank back and forth movement under the exogenic action), be provided with in the storage tank and pass the bellied gag lever post of joint (the gag lever post only one end links to each other with the storage tank inner wall and the other end is with storage tank inner wall spaced, thereby be convenient for the installation of jack catch strip 26 and spring), install on the gag lever post and support the protruding spring that just is located its both sides of joint (the spring has two promptly to in order to guarantee that jack catch strip 26 can in time reset).

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
