Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection machines, in particular to a clamping mechanism for optical detection of plane bearings. Background Art

[0002] Bearings are an important component used to support and reduce friction in mechanical devices. They are usually composed of an inner ring, an outer ring, rolling elements (such as balls or rollers) and a retainer. Bearings allow rotational motion and provide support between the shaft and the housing, reducing friction and making the mechanical system run more efficiently.

[0003] A Chinese patent discloses a bearing clamping mechanism for a bearing inspection machine (publication number: CN212887162U). The device supports the inner ring of the bearing through two rods, and then clamps the bearing with a wedge block and a round block. This is not only suitable for bearings of different sizes, but also can increase the stability of the bearing clamping; the motor drives the two rods to move toward the middle, so that the wedge block is separated from the bearing, so that the bearing is lifted up by the round block under the reset force of the first spring, which is convenient for taking out the bearing. However, the device still has the following defects during use:

[0004] Although the above device can clamp bearings of different sizes by adjusting the wedge block and the round block, the overall structure of the clamping device is semi-closed, which means that only the top of the bearing is exposed to the field of vision when it is clamped. When the other side of the bearing needs to be observed and inspected, the bearing needs to be separated from the clamping mechanism and turned over, and then a second installation is performed, which is more troublesome. Utility Model Content

When the worm 209 stops rotating, a self-locking is formed between the worm 209 and the worm wheel 208, and the worm wheel 208 cannot drive the worm 209 to rotate;

[0034] The bottom of the limit frame 201 and both sides of the worm gear 208 are fixedly installed with connecting shafts 211, and the connecting shafts 211 on both sides are symmetrically arranged.

[0037] The working principle of this utility model:

[0038] When the device is in use, firstly, the bearing is placed on the hollow inner wall of the middle part of the limit frame 201, and it is ensured that the bearing and each slider 205 are kept on the same horizontal plane, then the knob 210 is turned to drive the worm 209 to rotate, and then the worm 209 drives the worm wheel 208 to rotate when rotating, so that the rotating ring 202 rotates inside the limit frame 201, and at this time, the extrusion convex part 203 rotates the handle to drive the extrusion groove 207 to move, and at this time, the limit plate 206 is subjected to force and moves on the inner wall of the slide groove 204, and the limit plate 206 gradually approaches the bearing and clamps and fixes the side of the bearing;

[0039] Secondly, when it is necessary to detect the clamped bearing at different angles, pull the pull rod 217 outward and drive the movable plate 214 away from the clamping ring 212. At this time, the pin shaft 216 is gradually pulled out from the inner wall of the slot of the supporting foot 1. At this time, the limit frame 201 is pushed to make the connecting shaft 211 rotate on the inner wall of the supporting foot 1, so as to realize the angle change of the bearing inside the limit frame 201. After the adjustment is completed, release the pull rod 217, the spring 215 resets and stretches and pushes the pin shaft 216 to connect with the slot again, thereby completing the angle fixation of the limit frame 201.

[0040] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
