The position of the fixing fixture 3 along the radial direction of the rotating worktable 2 is adjustable. By adjusting the position of the fixing fixture 3, the position of multiple placement holes 31 can be adjusted. The appropriate placement hole 31 is selected according to the outer diameter of the sleeve, which facilitates the placement of the sleeve in the placement hole 31. The width of the first feeding groove 41 is adjustable. By adjusting the width of the first feeding groove 41, the width of the first feeding groove 41 is adapted to the outer diameter of the sleeve. The width of the second feeding groove 42 is adjustable. By adjusting the width of the second feeding groove 42, the width of the second feeding groove 42 is adapted to the outer diameter of the bolt. The device can automatically assemble sleeve bolts by adjusting the position of the fixing fixture 3, the width of the first feeding groove 41, and the width of the second feeding groove 42. The system can meet the assembly requirements of different types of sleeve bolts. The first moving component 51, the first transfer fixture 61 and the first gripping component 71 can transfer the sleeve conveyed by the first feeding trough 41 to the placement hole 31 of the fixed fixture 3 corresponding to the first feeding station. The second moving component 52, the second transfer fixture 62 and the second gripping component 72 can transfer the bolt conveyed by the second feeding trough 42 to the inner cavity of the sleeve in the placement hole 31 of the fixed fixture 3 corresponding to the second feeding station, thus completing the assembly of the sleeve bolt.
