Detailed Description

Embodiment 1 this embodiment provides a take radial play detection device of dabber bearing, including base, fixture and detection mechanism, the base includes bottom plate 11 and interval relative setting in backup pad one 12 and the backup pad two 13 of base both sides, fixture and detection mechanism set up promptly on backup pad one 12 and the backup pad two 13. In this embodiment, the clamping mechanism includes a first tip 2, a second tip 8, a first fixing pin 7, and a second fixing pin 7, horizontal through holes are formed in the first support plate 12 and the second support plate 13, the first tip 2 and the second tip 8 horizontally penetrate through the upper portions of the front sides of the first support plate 12 and the second support plate 13, respectively, and the first tip 2 and the second tip 8 are located on the same horizontal line. The first centre 2 and the second centre 8 are composed of a middle rod part, limiting rings 21 connected to two ends of the middle rod part and conical tips 22. The conical tips 22 of the first tip 2 and the second tip 8 are opposite (point to each other) and are spaced and opposite, and the gap between the conical tips 22 is used for placing the bearing with the mandrel.

When the first centre 2 and the second centre 8 are horizontally placed as shown in fig. 2, a V-shaped groove is formed in the top of the first centre along the axial direction of the first centre, and the opening of the V-shaped groove faces upwards and is preferably of a symmetrical structure. Vertical threaded through holes communicated with the horizontal through holes are further formed in the upper portions of the first supporting plate 12 and the second supporting plate 13, the first fixing pin 7 and the second fixing pin 7 are inserted into the vertical threaded through holes from the upper portions of the first supporting plate 12 and the second supporting plate 13 downwards through threads and are inserted into the V-shaped grooves to be screwed, and the first tip 2 and the second tip 8 are stably fixed on the positions suitable for the bearings with the mandrels. When the clamping device is used, the first tip 2 is fixed, one end of the bearing with the mandrel is in interference fit with the conical tip 22 of the first tip 2, then the conical tip 22 of the second tip 8 is pushed to be in interference fit with the other end face of the bearing with the mandrel, and the second fixing pin 7 is screwed up and fixed, so that clamping of the bearing with the mandrel is completed.

In this embodiment, detection mechanism includes measuring instrument, instrument clamp 5 and installation pole 4, fastening screw, and installation pole 4 also is horizontal setting and its both ends pass through screw fixed connection respectively in the rear side upper surface of backup pad one 12, backup pad two 13. The mounting rod 4 is provided with a sliding groove which is consistent with the connecting direction between the first support plate 12 and the second support plate 13. The instrument clamp 5 is slidably mounted on the sliding groove, one end of the instrument clamp 5 is fixed on the mounting rod 4 through a fastening screw, the other end of the instrument clamp extends towards the front side where the first tip 2 and the second tip 8 are located, and the measuring instrument is fixedly mounted at the end of the other end of the instrument clamp 5. The measuring instrument is a dial indicator 6 or a dial indicator. When the device is used, after the mandrel bearing is clamped and fixed, the tightness of the fastening screw is adjusted, so that the detection end of the measuring instrument can be matched with the middle part of the mandrel bearing, and the accuracy of a detection result is ensured.

Example 2 this example differs from example 1 in that: in this embodiment, the groove walls on both sides of the V-shaped groove are provided with a plurality of positioning strips. Specifically, the positioning strip is a strip-shaped protrusion which is obliquely arranged on the wall of the V-shaped groove, and the strip-shaped protrusion inclines towards the other end of the tip part far away from the tip. In order to ensure the antiskid and positioning of the strip-shaped protrusions on the fixing pins 7 and the inward pushing effect on the first tip 2 and the second tip 8, the inclination angle of the strip-shaped protrusions ranges from 10 degrees to 20 degrees. In addition, the distance between adjacent strip-shaped bulges is 1 mm-2 mm, so that the positioning strips are appropriate in density, and the phenomenon that the positioning strips are too dense or sparse and cannot play a fixing effect can be avoided.

To sum up, the utility model provides a simple structure, convenient to use take mandrel bearing's radial play detection device, its bayonet fixed knot through two top and fixed pin 7 constructs will take mandrel bearing centre gripping fixed, be furnished with adjustable position's measuring instrument again and detect, improved detection efficiency, satisfied actual user demand.
