Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a low-friction torque roller bearing press-fitting tool. Background Art

[0002] Roller bearing is a commonly used mechanical part used to support and reduce the friction and wear of the machine. Its function is to transfer loads through rolling contact, thereby reducing the friction and wear of machine parts, and also improving the efficiency and precision of the machine. Roller bearing is a type of rolling bearing and is one of the widely used components in modern machinery. It relies on rolling contact between the main components to support the rotating parts. Most roller bearings are now standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and easy selection.

When using the existing pressing device, the rollers need to be held by hand. The rollers are relatively small, which makes it inconvenient to operate during hand-held processing, and there is a risk of crushing fingers, thereby affecting the efficiency of installing the bearings. In order to solve this technical problem, the utility model proposes a low-friction torque roller bearing pressing tool. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a low friction torque roller bearing press-fitting tool comprises a base plate 1, the upper surface of the base plate 1 is connected to a support plate 2, the outer surface of the support plate 2 is connected to a fixing plate 3, the outer surface of the fixing plate 3 is provided with a fixing hole 1 4, the outer surface of the fixing plate 3 is provided with a fixing hole 2 5, the inner wall of the fixing hole 1 4 is connected to a hydraulic rod 6, the inner wall of the fixing hole 2 5 is connected to a cylinder 7, one end of the hydraulic rod 6 is connected to a movable plate 8, and the bottom surface of the movable plate 8 is connected to a push-pull rod 9.

[0024] The bottom end of the push-pull rod 9 is connected with a circular plate 10, the diameter of which is the same as the diameter of the gap in the cylinder 7, and the circular plate 10 can just enter the cylinder 7. The bottom surface of the circular plate 10 is connected with a contact plate 11, and the bottom surface of the contact plate 11 has a circular depression to facilitate the extrusion of the roller.

[0025] The circular plate 10 slides on the inner wall of the cylinder 7, and a groove 17 is provided on the inner wall of the cylinder 7. A protrusion 18 is connected to the outer surface of the circular plate 10, and the protrusion 18 slides on the inner wall of the groove 17. The presence of the groove 17 and the protrusion 18 can prevent the push-pull rod 9 from rotating, so that the push-pull rod 9 can only move up and down. The outer surface of the cylinder 7 is fixedly connected to an inlet pipe 12, and the bottom end of the cylinder 7 is connected to a rubber ring 13.

[0026] The inner wall of the rubber ring 13 is connected with a rubber cardboard 14. The roller will fall naturally onto the upper surface of the rubber ring 13 and will not pass through the rubber cardboard 14. The roller will only pass through the rubber cardboard 14 when it is squeezed to install the roller.

[0027] A placement plate 15 is provided above the base plate 1, and a side plate 19 is connected to the upper surface of the placement plate 15. A bidirectional threaded rod 20 is rotatably connected to the outer surface of the side plate 19. The threads at both ends of the bidirectional threaded rod 20 are in opposite directions. Small rings are provided at both ends of the bidirectional threaded rod 20 to prevent the bidirectional threaded rod 20 from detaching from the side plate 19. A telescopic rod 24 is connected to the upper surface of the base plate 1, and the top end of the telescopic rod 24 is connected to the bottom surface of the placement plate 15. There are four telescopic rods 24, which are evenly distributed above the base plate 1.

[0028] The upper surface of the placement plate 15 is connected to the bearing body 16, and the upper surface of the base plate 1 is slidably connected to a clamping plate 21. The outer surface of the clamping plate 21 is threadedly connected to the outer surface of the bidirectional threaded rod 20. There are two clamping plates 21, which are symmetrically distributed above the placement plate 15. One end of the bidirectional threaded rod 20 is connected to a handle 22. The outer surface of the clamping plate 21 is connected to a rubber strip 23. The rubber strip 23 can prevent the clamping plate 21 from excessively squeezing the bearing body 16 and causing damage, thereby playing a role in both fixing and protecting the bearing body 16.

[0029] There are two bidirectional threaded rods 20 symmetrically distributed above the placement plate 15. Turn the handle 22 to rotate the bidirectional threaded rod 20. At this time, the two clamps 21 approach each other so that the rubber strips 23 on the outer surfaces of the clamps 21 contact the bearing body 16 and fix it.

[0030] It should be noted that in actual use of the device, when installing the roller, it is necessary to first fix the bearing body 16 and turn the handle 22. The handle 22 drives the bidirectional threaded rod 20 to rotate. At this time, the two clamps 21 approach each other, and the rubber strip 23 on the outer surface of the clamp 21 contacts the bearing body 16 and fixes it. Then, the telescopic rod 24 is started to adjust the distance between the placement plate 15 and the cylinder 7, so that the rubber card plate 14 under the cylinder 7 contacts the bearing body 16, and the roller enters from the inlet pipe 12 into the cylinder 7. At this time, the hydraulic rod 6 is started, and the hydraulic rod 6 drives the push-pull rod 9 to move downward through the moving plate 8, and the push-pull rod 9 drives the circular plate 10 to move downward. At this time, the protrusion 18 slides on the inner wall of the groove 17, and the contact plate 11 contacts the roller and squeezes the roller downward, so that the roller slides out of the rubber card plate 14 and pushes the roller into the inside of the bearing body 16.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
