Description

Technical Field

[0001] The present invention relates to the technical field of bearing assembly tools, and particularly to a bearing assembly tool with a flipping and fixing device. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Therefore, the bearing has high machining accuracy and requires high installation accuracy. End covers are provided at both ends of the bearing. When assembling the bearing, the end covers need to be assembled. Existing bearing assembly tools need to position the balls between the inner ring and the outer ring, and mostly use a cage to position the balls. When assembling, the bearing needs to be turned over, and then the cage is assembled. However, the existing bearing assembly tools can only fix the inner ring and the outer ring of the bearing, and the turning over requires manual operation, resulting in poor efficiency. Therefore, we propose a bearing assembly tool with a flipping and fixing device. Summary of the Invention

[0003] The purpose of the present invention is to provide a bearing assembly tool with a flipping and fixing device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A bearing assembly tool with a flipping and fixing device, including a base. A vertical plate is provided on the top of the base. A motor is slidably connected to the front side wall of the vertical plate. A fixing block is provided on the front side wall of the vertical plate. A second electric telescopic rod is provided at the bottom of the fixing block, and one end of the second electric telescopic rod is connected to the top of the motor. The output end of the motor is connected to a flipping plate. First electric telescopic rods are provided on both the upper and lower side walls inside the flipping plate. Placement plates are provided at one end of each of the two groups of first electric telescopic rods. Outer ring fixing components are provided on the opposite side walls of the two placement plates.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1:

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a bearing assembly tooling with a flipping and fixing device, including a base 1. A vertical plate 2 is provided on the top of the base 1. A motor 8 is slidably connected to the front side wall of the vertical plate 2. A guiding groove is opened on the front side wall of the vertical plate 2. A guiding block matching the guiding groove is provided on the rear side wall of the motor 8. Under the action of the guiding groove and the guiding block, the motor 8 moves more stably up and down on the front side wall of the vertical plate 2. A fixing block 6 is provided on the front side wall of the vertical plate 2. A second electric telescopic rod 7 is provided at the bottom of the fixing block 6. One end of the second electric telescopic rod 7 is connected to the top of the motor 8. The output end of the motor 8 is connected with a flipping plate 3. First electric telescopic rods 4 are provided on both the upper and lower side walls inside the flipping plate 3. Placement plates 5 are provided at one ends of the two groups of first electric telescopic rods 4. Outer ring fixing components 11 are provided on the opposite side walls of the two groups of placement plates 5. Chutes 10 are opened on the opposite side walls of the two groups of placement plates 5. Inner ring fixing components 9 are provided in the two groups of chutes 10.

[0019] Please refer to Figure 3 , the outer ring fixing component 11 includes two outer fixing plates 110 slidably connected to the top of the placement plate 5. Mounting blocks 112 are provided on both the left and right sides of the top of the placement plate 5. Third electric telescopic rods 111 are provided on the opposite side walls of the two groups of mounting blocks 112. One ends of the two groups of third electric telescopic rods 111 are respectively connected to the outer side walls of the two groups of outer fixing plates 110. The outer fixing plates 110 are arranged in an arc shape.

[0020] Please refer to Figure 4 , the inner ring fixing component 9 includes a bidirectional lead screw 91 provided in the chute 10. One end of the bidirectional lead screw 91 is connected to a bearing provided on the left side wall inside the chute 10. A driving motor 93 is provided on the right side wall of the placement plate 5. The output end of the driving motor 93 penetrates through the right side wall of the placement plate 5 and is connected to one end of the bidirectional lead screw 91. Sliders 92 are sleeved on both the left and right sides of the outer wall of the bidirectional lead screw 91. A limiting groove is opened at the bottom inside the chute 10. Limiting blocks matching the limiting groove are provided at the bottoms of the two groups of sliders 92. Under the action of the limiting groove and the limiting blocks, the sliders 92 move more stably on the outer wall of the bidirectional lead screw 91. Inner fixing plates 90 are provided at the tops of the two groups of sliders 92. The inner fixing plates 90 are arranged in an arc shape.

[0021] Working principle: When the cage of the bearing needs to be assembled, the bearing is placed on the lower placement plate 5 (at this time, the bearing is composed of balls, inner ring and outer ring), and then the third electric telescopic rod 111 drives the outer fixing plate 110 to fix the outer ring. The driving motor 93 drives the bidirectional lead screw 91 to rotate. Under the action of the limiting groove and the limiting block, the two groups of sliders 92 move relative to the outer wall of the bidirectional lead screw 91. The slider 92 drives the inner fixing plate 90 to fix the inner ring (the heights of the inner fixing plate 90 and the outer fixing plate 110 can only fix the lower part of the outer wall of the bearing). Then the external assembly device assembles the cage (this is the prior art). When the other side of the bearing needs to be assembled, the first electric telescopic rod 4 above drives the upper placement plate 5 to squeeze the bearing, and then the inner fixing plate 90 and the outer fixing plate 110 fix the bearing. Then the motor 8 drives the turning plate 3 to rotate and turn over. At this time, the inner fixing plate 90 and the outer fixing plate 110 located above loosen the bearing, and the first electric telescopic rod 4 drives the upper placement plate 5 to move upward. Thus, the external assembly device assembles the cage, completing the assembly of the cages on both sides without manual turning over;

[0022] When assembling the cage, the second electric telescopic rod 7 drives the motor 8 to move downward, and the motor 8 drives the turning plate 3 to move downward to contact the base 1, ensuring the stability of the assembly.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
