The heating mechanism 6 includes a heating head 61 located above the corresponding work station 3 and used for heating the outer ring 4. The assembly mechanism 7 includes a press-fitting head 71 located above the corresponding work station 3. An air gripper 72 for clamping the inner ring winding assembly 5 is installed inside the press-fitting head 71.

[0016] As Figure 2As shown in the figure, the heating device includes a first bracket 62 fixed to the top of the left end of the workbench 1. A first lifting cylinder 63 extending vertically is fixed to the top of the first bracket 62. The end of the piston rod at the lower end of the first lifting cylinder 63 is fixed with a lifting platform 64. The heating head 61 is fixed to the right end of the lifting platform 64, and a heating tube 611 is provided at the lower end of the heating head 61. On the right side of the upper end of the first bracket 62, there is a track 65 extending vertically. The left end of the lifting platform 64 is in sliding fit with the track 65 vertically. The first lifting cylinder 63 can drive the heating head 61 to move up and down. After the heating head 61 moves downward, the heating tube 611 can extend into the outer ring 4 to heat the outer ring 4, causing the outer ring 4 to expand due to heat.

[0017] As Figure 3 and Figure 4 As shown in the figure, the assembling mechanism 7 includes a second bracket 73 fixed to the top of the rear end of the workbench 1. A rodless cylinder 74 extending horizontally is installed at the upper end of the second bracket 73. A sliding table 741 of the rodless cylinder 74 is fixedly connected with a movable table 75.
