However, the applicant believes that the adjustability of the assembly table body in the prior art is poor, and the bearings cannot be adjusted to the appropriate position for operation according to the habits of different assemblers. If it is not conducive to the operation of the assemblers, the long-term assembly work will increase the labor intensity of the assemblers, and the coaxiality will affect the bearing assembly accuracy and reduce work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a bearing assembly table to solve the problems that the assembly table body in the prior art proposed in the above background technology has poor adjustability, cannot adjust the bearing to a suitable position for operation according to the habits of different assemblers, is not conducive to the operation of the assemblers, and the labor intensity of the assemblers is increased during long-term assembly work.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Example:

[0029] See also Figure 1-Figure 5 A bearing assembly table includes an operating table 1, a connecting plate 3 is arranged above the operating table 1, a connecting seat 4 is fixedly connected to the middle part of the upper part of the connecting plate 3, a positioning cylinder 9 is rotatably connected to the upper part of the connecting seat 4, a threaded rod 10 is rotatably connected to the interior of the positioning cylinder 9, an extension rod 11 is fixedly connected to the upper end of the threaded rod 10, the other end of the extension rod 11 extends from the interior of the positioning cylinder 9 to the outside and is fixedly connected to an adjustment handle 12, a fixing member 13 is slidably connected to the interior of the positioning cylinder 9, and the fixing member 13 is threadedly connected to the threaded rod 10, a plurality of extension blocks 14 are fixedly connected to the outer wall of the fixing member 13 at equal intervals on the circumference, and the other ends of the plurality of extension blocks 14 extend from the interior of the positioning cylinder 9 to the outside The other end of the extension block 14 is slidably connected with an elastic rod 15, and the other end of the elastic rod 15 is fixedly connected with a stop block 16. The outer surface of the stop block 16 is fixedly connected with an anti-slip layer 17. In order to target some precision bearings that need to be manually assembled, the operating table 1 plays the main role of supporting and completing the assembly work. The precision bearing to be assembled is sleeved on the outside of the positioning cylinder 9. The fixing part 13 is mainly used to fix the bearing. The threaded rod 10 can be driven to rotate from the outside through the adjustment handle 12 and the extension rod 11. Since the fixing part 13 is threadedly connected with the threaded rod 10, the threaded rod 10 rotates the fixing part 13 to adjust the height along the positioning cylinder 9, so as to adapt to different assembly personnel for operation;

[0030] In addition, the extension block 14 can increase the stability of the fixing member 13 on the one hand, and can increase the telescopic distance of the elastic rod 15 on the other hand. The simultaneous contraction of multiple groups of elastic rods 15 makes it easier for the bearing sleeve to be arranged on the outside of the fixing member 13. When the elastic rods 15 are extended at the same time, the abutment block 16 is expanded to abut and fix the bearing. The anti-slip layer 17 can be made of rubber or other materials to increase the friction between the abutment block 16 and the bearing.

[0031] Specifically, the end of the positioning cylinder 9 away from the adjusting handle 12 is fixedly connected to the connecting block 6, the connecting block 6 is arranged inside the connecting seat 4, and the port of the connecting seat 4 is fixedly connected to the sealing plate 5. The positioning cylinder 9 can drive the bearing fixed by the fixing part 13 to rotate along the connecting seat 4, so that the assembler can rotate the bearing after the bearing is fixed to change the observation and assembly range. The positioning cylinder 9 is connected to the connecting seat 4 through the connecting block 6, and the sealing plate 5 can seal the port of the connecting seat 4.

[0032] Specifically, the outer wall of the connecting block 6 is fixedly connected with a plurality of protrusions 7 at equal intervals around the circumference, and a spring sheet 8 is fixedly connected to the inner wall of one side of the connecting seat 4. The protrusions 7 abut against each other, and the positioning cylinder 9 rotates while driving the connecting block 6 and the protrusions 7. The spring sheet 8 abuts between the two groups of protrusions 7, thereby increasing the limiting effect on the connecting block 6 and preventing the positioning cylinder 9 from rotating easily to affect the stability of the bearing during assembly.

[0033] Specifically, a limiting block 18 is fixedly connected to the lower middle portion of the connecting plate 3, a limiting groove 19 is provided at the upper middle portion of the operating table 1, the limiting block 18 is slidably connected to the limiting groove 19, and both the limiting block 18 and the limiting groove 19 are arranged in a T shape, so that the connecting plate 3 is initially connected to the operating table 1, and the connecting plate 3 can be adjusted forward and backward along the limiting groove 19 so that the assembler can adapt to different operating distances.

[0034] Specifically, both sides of the connecting plate 3 are provided with sockets 20, and a plurality of fixing holes 21 are evenly spaced above the operating table 1 and on both sides of the limiting groove 19. Fixing bolts 22 are inserted between the sockets 20 and the fixing holes 21. When the connecting plate 3 is adjusted to a suitable position, the sockets 20 correspond to the closest group of fixing holes 21, and the fixing bolts 22 are inserted between the sockets 20 and the fixing holes 21, so that the connecting plate 3 is fixedly connected to the operating table 1.

[0035] Specifically, an expansion board 2 is fixedly connected to one side of the operating table 1, a gooseneck tube 23 is fixedly connected to the expansion board 2, and a lighting lamp 24 is fixedly connected to the other end of the gooseneck tube 23. The expansion board 2 is connected to the operating table 1 as a whole. Drawings, bearing assembly tools and other objects required by assemblers can be placed on the expansion board 2. At the same time, the lighting lamp 24 helps assemblers to clearly observe the assembly process, and the angle of the lighting lamp 24 can be adjusted at will through the gooseneck tube 23.

[0036] Working principle:

[0037] When in use, the connecting plate 3 can be adjusted forward and backward along the limit groove 19 so that the assembler can adapt to different operating distances. When the connecting plate 3 is adjusted to a suitable position, the socket 20 corresponds to the closest set of fixing holes 21, and the fixing bolt 22 is inserted between the socket 20 and the fixing hole 21, so that the connecting plate 3 is fixedly connected to the operating table 1. The precision bearing to be assembled is sleeved on the outside of the positioning cylinder 9. The fixing part 13 is mainly used to fix the bearing. The threaded rod 10 can be driven to rotate from the outside through the adjusting handle 12 and the extension rod 11. Since the fixing part 13 is threadedly connected to the threaded rod 10, the threaded rod 10 rotates the fixing part 13 and the height can be adjusted along the positioning cylinder 9 to adapt to different assemblers for operation.
