Description

Technical Field

[0001] The present invention belongs to the technical field of bearing measurement, and particularly relates to a bearing clamping and measuring device and a using method thereof. Background Art

[0002] Bearings are the core components of mechanical operation. Especially for mechanical equipment, the operating state of the bearings directly affects the normal operation of the equipment. Therefore, the processing quality of the bearings is directly related to the operating condition of the equipment.

[0003] At present, most bearing enterprises still rely on manual sampling measurement with measuring tools for the size measurement of the inner and outer rings of bearings during the production process. Therefore, it is difficult to measure all the inner and outer rings of the bearings, and missed inspections often occur. The test results are greatly affected by the subjective factors of the test personnel, and the measurement efficiency is low. In addition, for small bearings, the bearing weight is small and manual measurement is relatively convenient. For medium and large bearings, the weight of the inner and outer rings of the bearings is large. Manual measurement not only has a high labor intensity, but also is prone to safety accidents.

Specifically:

[0033] The driving gas provided by the external device is transported through the hollow part of the driven shaft 23 to the high-pressure air pipe 36 of the rotary joint 34, and then transported to the air cylinder 31. Under the action of the driving gas, the piston rod of the air cylinder 31 moves in the direction close to the driving ejector rod 35;

[0034] The movement of the piston ejector rod of the air cylinder 31 drives the driving ejector rod 35 to move, and makes the ball hinge top block 352 move along the wedge-shaped guiding surface 45 of the fixture 42, thereby driving the fixture 42 to move.

[0035] The fixture 42 moves away from the ball hinge top block 352 under the action of the ball hinge top block, and at the same time, the anti-slip groove 43 of the fixture 42 acts on the inner surface of the inner ring or outer ring of the bearing, thereby clamping the bearing and placing it on the measuring table used in industrial production;

The device includes a support 1, a transmission mechanism 2, a driving mechanism 3, and a measuring mechanism 4. When using the device for measurement, an external device provides driving gas, and the driving gas is transmitted to the driving mechanism 3 through the transmission mechanism 2 to make the driving mechanism 3 move, thereby driving the measuring mechanism 4 to move and clamp the bearing, and then cooperating with the measuring table used in industrial production to complete the measurement of the bearing diameter.
