The adjacent second shaft 93 is then moved forward under gravity and vibration to the position of the opening 4161, at which point the shaft stop 417 is again actuated and re-held in place against the second shaft 93. After the shaft transfer member 414 moves the shaft 93 to a position directly above the assembling die 8, the shaft clamping jaws 4151 are released so that the shaft 93 falls vertically, and the shaft transfer member 414 drives the shaft clamping jaws 4151 to return to the position of the second shaft 93 and clamp the second shaft 93. The above steps are repeated to complete the loading operation of the shaft rod 93.

Referring to fig. 9, the hold-down assembly 42 includes a third mounting bracket 421, a shaft hold-down power member 425, and a shaft hold-down member 426.

When the piston rod of the cylinder is extended downward, the shaft pressing member 426 can press down the shaft 93 located in the assembling die 8 so that the assembling is tight.

In order to prevent the shaft 93 from tilting when being pressed down to cause assembly deviation, a conduit placing power part 422 is mounted on the third mounting frame 421, where the conduit placing power part 422 may be an air cylinder, and a piston rod of the air cylinder is vertically arranged. The conduit placing power member 422 is connected with a connecting plate 423, the connecting plate 423 is horizontally arranged and vertically fixed with a conduit 424, and the conduit 424 is arranged towards the rotary table 1 and coaxially located below the shaft rod lower member 426. The inner diameter of the catheter 424 is no less than the maximum profile outer diameter of the shaft 93, and the length of the catheter 424 is adapted to the length of the shaft 93.

When the assembling die 8 moves to a position right below the shaft down-pressing member 426, the guide tube 424 is inserted into the assembling die 8 downward under the action of the guide tube placing power member 422, and the guide tube 424 simultaneously presses down the bearing 92 so that the bearing 92 is tightly fitted and fastened with the end cover 91. Then the shaft 93 is moved above the assembling die 8 by the shaft transfer member 414 and inserted downward from the guide tube 414, and the shaft lower member 426 is moved downward by the shaft lower driving member 425 and presses the shaft 93, so that the shaft 93 is inserted into the inner race of the bearing 92 and fixed. The shaft down power member 425 then lifts the shaft down member 426 and the conduit 424 is lifted off the assembly mold 8 by the conduit placement power member 425.

A fourth supporting frame 511 is fixed to one end of the sleeve conveying groove 51 close to the feed opening 512, a sleeve limiting member 52 is mounted on the fourth supporting frame 511, the sleeve limiting member 52 may be an air cylinder, and a piston rod of the air cylinder is vertically arranged and an end portion of the piston rod can extend into the sleeve conveying groove 51 to prevent a sleeve 94 close to the feed opening 512 from moving forward.

In order to prevent the sleeve 94 from moving to the feed opening 512 and directly falling outside the assembling die 8, a supporting plate 53 is fixedly connected to one end of the sleeve conveying groove 51 close to the feed opening 512, the supporting plate 53 is located below the feed opening 512 and provided with a slot 531, an inserting plate 54 is inserted into the slot 531, a sleeve feed power part 55 is fixed to one end of the inserting plate 54 far away from the feed opening 512, the sleeve feed power part 55 can be an air cylinder, and a piston rod of the air cylinder is horizontally arranged. The sleeve blanking power part 55 can be fixed to the support by means of a rock mix. The side wall of the sleeve conveying groove 51 near the feed opening 512 is provided with a sensor, and the sensor is electrically connected with the sleeve limiting piece 52 and the sleeve feeding power piece 55 to an external processor such as a computer.

When the sleeve 94 moves to the position of the feed opening 512, the sleeve stopper 55 blocks the adjacent second sleeve 94, and the insert 54 seals the feed opening 512. When the assembling die 8 moves to a position right below the feed opening 512, the sleeve feed power part 55 drives the insert plate 54 to move and open the feed opening 512, and the sleeve 94 falls into the assembling die 8 under the action of gravity and is sleeved outside the shaft rod 93.

In order to reduce the possibility that the sleeve 94 may be jammed by the contact of the sleeve 94 with the assembling die 8, a mold opening mechanism 7 is also installed below the sleeve conveying groove 51 to open the assembling die 8.

After the sleeve 94 is placed, the assembling die 8 moves to the next bearing mounting mechanism 3, the bearing magnetic suction head 323 sleeves the bearing 92 on the shaft rod 93, and the bearing 92 presses the sleeve 94 downwards in the process until the bearing 92 is fixedly sleeved on the shaft rod 93 at the designed position. The bearing magnetic tip 323 then leaves the assembly die 8 and the assembly die 8 moves with the turntable to the station of the take off mechanism 6.

Referring to fig. 12, the material taking mechanism 6 includes a fifth support frame 61, a material taking lifting member 62 is fixed on the top of the fifth support frame 61, where the material taking lifting member 62 may be an air cylinder, and a piston rod of the air cylinder is vertically arranged; a horizontally arranged cantilever 63 is fixed at the lower end of the material taking lifting piece 62, and a guide rod 631 is horizontally fixed on the cantilever 63; the cantilever 63 has an axle take-off transfer member 64 mounted thereon, where the axle take-off transfer member 64 may be a linear motor that is movable along a guide bar 631.

In order to facilitate the clamping operation of the material taking mechanism 6, the bottom of the fifth supporting frame 61 is provided with a mold opening mechanism 7 for opening the assembling mold 8.

After the assembling die 8 is opened, the axle taking and transferring piece 64 drives the axle clamping jaw 651 to move right above the assembling die 8, then the taking and lifting piece 62 drives the cantilever 63 to move downwards, the axle taking piece 65 clamps the axle 9, and the taking and lifting piece 62 drives the cantilever 63 to move upwards so that the axle 9 leaves the assembling die 8. Axle take-off transfer member 64 then moves along guide bar 631 over pick-up channel 66 and axle clamp jaws 651 of axle take-off member 65 are released.

In the embodiment of the present application, besides the air cylinder, other mechanical structures that linearly reciprocate can be adopted for all components that linearly reciprocate, such as a linear stepping motor, a screw rod transmission mechanism, and the like.
