The bottom end surface of the mounting shaft 22 is provided with an elastic member (not shown in the figure) for supporting the bottom end surface of the mounting shaft, so that the mounting shaft 22 is suitable for moving up and down in the cavity of the upright 21 and can return to the original position under the elastic force of the elastic member, namely, after the bearing assembly is completed, the elastic member can spring the mounting shaft 22, thereby lifting the assembled bearing fixed on the mounting shaft 22, and facilitating the picking and placing of the assembled bearing;
As shown in fig. 1, a pressing part 3 is disposed above the placement component 2, the pressing part 3 includes a bracket 31, a driving part is disposed on the bracket 31, the driving part is an air cylinder 32, the air cylinder 32 is fixedly mounted on the bracket 31, an output end of the air cylinder 32 is disposed towards a direction where the placement component 2 is located, and an output end of the air cylinder 32 is connected with a compression ring 33 for moving downwards under the driving of the air cylinder 32 until contacting with the bearing inner ring and pushing the bearing inner ring towards a direction where the bearing outer ring is located until the assembly of the bearing is completed.
Embodiment two:
In the assembly process of the bearing, the problems of incomplete assembly caused by the fact that the inner ring and the outer ring are not placed in the same axial center, insufficient lubrication, the cylinder 32 and the like can lead to incomplete assembly of the inner ring and the outer ring of the bearing, and after the cylinder 32 completes expansion and contraction of one stroke, the mounting shaft 22 can move upwards under the support of the elastic device no matter whether the bearing is assembled or not, and whether the bearing is assembled completely cannot be determined, so that improvement is made in the embodiment;
As shown in fig. 2-4, a spacer 24 is arranged in the cavity of the upright 21, a sliding block 26 is arranged in the spacer 24 in a sliding manner, the sliding block 26 is suitable for sliding in the spacer 24 along the vertical direction, and the mounting shaft 22 is not directly arranged in the cavity of the upright 21 but is fixed on the sliding block 26 and can synchronously move with the sliding block 26, meanwhile, an elastic connecting piece is arranged at the bottom of the sliding block 26, the elastic connecting piece is a spring 27, and the spring 27 is used for supporting the sliding block 26 and providing elasticity for the sliding block 26;
A second spring (not shown) is provided between the output end of the cylinder 32 and the pressing ring 33, and the elastic force of the second spring is greater than that of the spring 27;
A rotating rod 28 is rotatably connected to the side surface of the sliding block 26, one end of the rotating rod 28 is rotatably connected to the sliding block 26, a torsion spring (not shown in the figure) is arranged at the connecting position of the rotating rod 28 and the sliding block 26, and the other end of the rotating rod 28 is provided with a protrusion 29, so that the rotating rod 28 is suitable for synchronously moving with the sliding block 26;
A guide plate 30 is fixed on the inner wall of the spacer 24, meanwhile, a sliding groove 25 is formed in the side face of the spacer 24, the sliding groove 25 is provided with a first inclined plane 251 and a second inclined plane 252, meanwhile, the guide plate 30 is provided with a third inclined plane 301 and a fourth inclined plane 302, a first residence point 303 is arranged between the third inclined plane 301 and the fourth inclined plane 302, and the first residence point 303 is arc-shaped;
When the bearing assembly is assembled, after the bearing assembly is put in place, the cylinder 32 is opened, the compression ring 33 is driven by the cylinder 32 to move downwards and contacts the bearing inner ring in the continuous moving process, and after the bearing inner ring is continuously moved, the bearing inner ring is pushed downwards together with the mounting shaft 22, and because the mounting shaft 22 is fixed with the sliding block 26 in the embodiment, the sliding block 26 also slides downwards in the spacer 24 and compresses the spring 27;
In the process of moving the slide block 26, the rotating rod 28 is driven to synchronously move, the protrusion 29 is contacted with the third inclined surface 301, and when the slide block 26 continues to move, the third inclined surface 301 supports and guides the protrusion 29, so that the rotating rod 28 rotates and drives the torsion spring to twist, and the state can be seen from the first split view and the second split view in fig. 5;
When the protrusion 29 reaches the position of the chute 25, the torsion spring will reset due to the fact that the protrusion 29 loses the support of the third inclined surface 301, and then the rotating rod 28 is driven to rotate reversely, so that the protrusion 29 enters the chute 25 along the first inclined surface 251;
At this time, the cylinder 32 is closed, the compression force of the spring 27 drives the slider 26 to move upwards, so as to drive the protrusion 29 to move along the first inclined plane 251, and the protrusion is fixed after reaching the first standing point 303, and the position can be used as an observation position, and the state can be referred to as a third split diagram in fig. 5;
If the bearing is completely assembled, the bearing can be moved downwards in a manual pressing mode, the boss 29 can move along the second inclined plane 252, the rotating rod 28 continues to rotate under the action of the torsion spring, the compression force of the spring 27 drives the sliding block 26 to move upwards, and the boss 29 is driven to contact the fourth inclined plane 302 and move along the fourth inclined plane 302, and the state can be seen from a fourth split diagram in fig. 5;
After the spring 27 is restored, the sliding block 26 is sprung, the rotating rod 28 is restored to the initial angle, and the state can be referred to as a fifth split drawing in fig. 5, and the assembled bearing is lifted at the moment, so that the bearing is convenient to take and place;
When the bearing is not completely assembled and the inner ring is not completely pressed into the outer ring, the protrusion 29 is kept on the third inclined plane 301 and stays before the second standing point 304, the bearing cannot reach the observation position after the cylinder 32 is retracted, but is directly sprung up, at the moment, the cylinder 32 is continuously opened after the bearing assembly is required to be adjusted, the process is repeated until the bearing is completely assembled, and thus, when the bearing is not completely assembled, a prompt is quickly sent out, and the assembly efficiency of the bearing is improved.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
