Problems solved by technology
In this way, knocking is easy to cause damage to the surface of the ball, and the relative rotation of the inner star wheel and the outer star wheel will have an adverse effect. At the same time, during the assembly process, the ball needs to be held by hand to prevent position changes. During the knocking process, the ball is constantly adjusted artificially. location, the production efficiency is low, and it is easy to cause injuries to workers

Embodiment Construction
[0049] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.
[0050] In this embodiment, a device for assembling the balls of the inner star wheel is provided, such as figure 1 with figure 2 Shown is a structural schematic diagram of the inner star wheel ball assembly device on the worktable 13, assembling the balls between the inner star wheel 9 and the outer star wheel 10. image 3 with Figure 4 It is a schematic diagram of the structure after the balls are assembled between the inner star wheel 9, the cage 14 and the outer star wheel 10. When the above-mentioned inner star wheel ball assembly device assembles the balls 20, the inner star wheel 9 and the cage 14 are already assembled as a whole, and then the balls 20 are assembled between the inner star wheel 9 and the outer star wheel 10 by this device.
[0051] Specifically, combine Figure 5-8 As shown, Figure 7 It is a schematic diag...

The invention relates to the technical field of inner star wheel tools, and discloses an inner star wheel ball assembling device. The device comprises a push rod, an outer conical part, a clamping jaw, an external pressing part, an outer sleeve and an elastic part; the outer conical part is arranged at one end of the push rod, and comprises an outer conical portion, the diameter, in the directionaway from the push rod, of the outer conical portion is gradually increased, the clamping jaw is arranged on the periphery of the outer conical portion, the external pressing part is arranged on the push rod in a sleeving manner, and can slide relative to the push rod, the inner wall of the external pressing part is provided with an inner conical portion matched with the outer conical portion, theouter sleeve is arranged outside the push rod in a sleeving manner, and can slide relative to the push rod, one end of the clamping jaw can stretch out of or retract into the outer sleeve, the elastic part is arranged on the push rod in a sleeving manner, abut-pressing portions are arranged on the push rod and the outer sleeve, and the elastic part is located between the two abut-pressing portions. A ball between an inner star wheel and an outer star wheel can be rapidly mounted, mounting accuracy is ensured, and life safety of a worker is ensured.
Description
Technical field [0001] The invention relates to the technical field of inner star wheel tooling, in particular to an inner star wheel ball assembly device. Background technique [0002] With the development of technology in the domestic automobile industry, the structural requirements for the key transmission components of automobiles are becoming higher and higher. A number of balls are arranged between the inner star wheel and the outer star wheel, and the balls are positioned via a cage arranged between the inner star wheel and the outer star wheel. When installing the balls, it is difficult to assemble all the balls between the inner star wheel and the outer star wheel at one time due to the unique helix surface and eccentric arc ball path of the inner star wheel and the outer star wheel. [0003] The usual way is to place the balls between the outer planet wheel and the cage, and press the balls one by one into the inner planet wheel and the outer planet wheel so that the bal...
