Description

Technical Field

[0001] The utility model relates to the field of bearing detection tooling, in particular to a bearing fixing tooling suitable for bearing aperture detection. Background Art

[0002] Bearings are an important mechanical foundation, and their main function is to support rotating parts and reduce friction. Depending on the direction of force, bearings can be classified into sliding bearings and rolling bearings. Rolling bearings are further divided into single-row, double-row, self-aligning ball bearings and self-aligning roller bearings. When producing bearings, the aperture needs to be tested to ensure the quality of the bearings.

[0003] After searching, the application number is "202110654732.2", which provides a bearing fixing tool for bearing aperture detection. The bearing sleeve is mounted on the clamping shaft 2, and then the driving mechanism is turned on. The driving mechanism drives the screw rod 4 to rotate. Since the screw rod 4 is threadedly connected to the slider 5, the slider 5 can move up and down after the screw rod 4 rotates. Since the outer peripheral surface of the slider 5 is a conical surface, the conical surface shrinks downward, and the top block 3 of the clamping shaft 2 is also provided with an inclined surface, and in the direction close to the screw rod 4, the inclined surface is inclined downward, and the inclined surface abuts against the conical surface. Therefore, when the slider 5 moves downward, the top block 3 can be pushed to move outward, and then all the clamping shafts 2 around the screw rod 4 can move outward at the same time until the bearing is stuck and fixed. When the bearing is stuck and fixed, the detection tool can be used to detect the aperture of the bearing.

[0004] The above-mentioned clamping shaft controlled twice by the screw rod limits the bearing, which is convenient for the detection of the hole diameter at the back. However, when this structure is used, the staff needs to take out the bearing and clamp it, and then detect the hole diameter. When the number of bearings to be tested is large, the staff must wait for the test to be completed before placing the bearing in the clamping area. The test cannot be performed continuously, and the detection speed is reduced. Utility Model Content
