Description

Technical Field

[0001] The utility model relates to the technical field of bearing production and processing, in particular to a bearing clamp. Background Art

[0002] During the production and processing of bearings, the bearings need to be slotted, ground, polished, tested, transferred, and other steps. These steps require the bearings to be clamped. The existing bearing clamping method is mainly to clamp and grab by fixtures or manipulators.

[0003] For example, patent application number CN201820185146.1 discloses a bearing surface picking robot, which clamps and moves the bearing by moving two grabbing bars 10 on the grabbing arm 7 back and forth. The grabbing arm 7 is installed on a baffle at one end of the second hydraulic column 6, and the second hydraulic column 6 is connected to the inside of the second hydraulic pump 5. The mounting frame 3 is connected to the second hydraulic pump 5 through the oil tanks 4 at both ends. When working, the second hydraulic pump 5 drives the grabbing arm 7 to extend forward through the second hydraulic 6 columns, and then the first hydraulic pump 1 drives the mounting frame 3 to move downward through the first hydraulic column 2, so that the mounting frame 3 drives the grabbing arm 7 to move downward through the second hydraulic pump 5. The PLC controller 13 with model CPM1A in the control panel 8 of the grabbing arm 7 controls the two The two third hydraulic pumps 11 at the ends work, and the third hydraulic pump 11 extends out through the third hydraulic column 12. One end of the third hydraulic column 12 is welded to the connecting rod 17 of the grabbing bar 10. Then the two third hydraulic columns 12 push the two grabbing bars 10 to reduce the distance between them, so that the two grabbing bars 10 can grab the bearing. After grabbing, the first hydraulic pump 1 and the second hydraulic pump 5 work to move the bearing. The bearing is grabbed and moved synchronously by the two grabbing arms 7 to ensure that the working efficiency of the manipulator is higher. The grabbing foot 18 under the grabbing bar 10 is provided with an arc-shaped grabbing groove 19. The grabbing groove 19 matches the arc size of the grabbed bearing, ensuring that the two grabbing bars 10 are more firmly grabbed when grabbing and moving the bearing.

[0004] This patent in the prior art mainly uses grabbing bars to grab, but there are only two existing grabbing bars, and the stability is poor during the grabbing process. The grabbing bars are provided with grabbing grooves, but the upper and lower surfaces of the bearing are both flat. Therefore, when the bearing is placed on the plane, the grabbing grooves cannot grab the bearing. Therefore, this patent in the prior art has great limitations when used. Utility Model Content
