The inner walls on both sides of the guide groove 23 are connected to the first connecting rod 22 by rotating shafts, and the outer surface of the first connecting rod 22 is hinged to the first hinge seat 29 by the rotating shaft. The top of the first hinge seat 29 is slidably connected to the bottom end of the connecting frame 7. The lower inner wall of the guide groove 23 is slidably connected to the second hinge seat 25, and the inner wall of the second hinge seat 25 is hinged to the second connecting rod 24 by the rotating shaft. The second connecting rod 24 and the first connecting rod 22 are hinged by the rotating shaft. Then, the outer surface of the second connecting rod 24 is hinged with a third hinge seat 21 through a rotating shaft, and the top of the third hinge seat 21 is fixedly connected to one side of the bottom end of the connecting frame 7, and the upper part of one end of the second hinge seat 25 is fixedly connected to a cross bar 28. A limiting groove 27 for cooperating with the cross bar 28 is opened on the inner wall of one side of the guide groove 23. A telescopic gas rod 26 is fixedly connected to the inner wall of one side of the mobile frame 6, and the output end of the telescopic gas rod 26 is fixedly connected to one end of the cross bar 28. The mounting frame 1 provides a stable support structure for the entire device. The assembler body 4 and the assembly seat 5 cooperate to ensure that the wheel hub bearing is assembled in a dedicated working area. The shifting mechanism 3 facilitates the shifting of the assembled wheel hub bearing. The ejection assembly 2 is used to eject the assembled wheel hub bearing. The output end of the telescopic gas rod 26 drives the cross bar 28 to move. The movement of the cross bar 28 drives the second hinge seat 25 to move. The second hinge seat 25 moves to cooperate with the second connecting rod 24, the first connecting rod 22, the first hinge seat 29 and the third hinge seat 21 to move the connecting frame 7. The connecting frame 7 moves to eject the assembled wheel hub bearing.

[0018] The shift mechanism 3 includes a mounting groove 33, which is provided on the lower inner wall of the mounting frame 1. The lower inner wall of the mounting groove 33 is fixedly connected to a support plate 36. The top of the support plate 36 is fixedly connected to a motor 37, and the output end of the motor 37 is fixedly connected to a worm 38.

The lower inner wall of the mounting frame 1 is provided with a long groove 34, and the inner wall of one side of the long groove 34 is rotatably connected to a screw rod 302. One end of the rotating rod 301 passes through the inner wall of one side of the mounting groove 33 and is fixedly connected to one end of the screw rod 302. The outer surface of the screw rod 302 is threadedly sleeved with a connecting block 35, and the top of the connecting block 35 is fixedly connected to one side of the bottom end of the movable frame 6. The motor 37 drives the rotating rod 301 to rotate through the worm 38 and worm gear 39, thereby driving the screw rod 302 to rotate. The screw rod 302 cooperates with the thread of the connecting block 35 to convert the rotational motion into linear motion, driving the movable frame 6 to shift precisely. The movement of the movable frame 6 causes the ejected hub bearing to be displaced, thereby improving the unloading efficiency of the unloading device.

[0019] The inner wall of the connecting frame 7 is slidably provided with a pneumatic clamping rod 8, which can slide in the connecting frame 7 to facilitate clamping and fixing the wheel hub bearing and improve stability during the blanking process.

The U"-shaped mobile frame 6 facilitates the movement of the mobile frame 6 and avoids motion interference.

[0021] Correspondingly, the first connecting rod 22 and the second connecting rod 24 are arranged in an "X" shape. The "X"-shaped first connecting rod 22 and the second connecting rod 24 can provide more stable support and greater ejection force during the ejection process, thereby improving the efficiency and stability of the ejection operation.

[0022] The two ends of the second hinge seat 25 are respectively slidably connected to the inner walls on both sides of the guide groove 23. One end of the cross bar 28 passes through the limiting groove 27, and the two ends of the cross bar 28 are respectively slidably connected to the inner walls on both sides of the limiting groove 27. The second hinge seat 25 slides in the guide groove 23 to ensure the stability and directionality of its movement. The cross bar 28 slides in the limiting groove 27 to limit the movement range of the second hinge seat 25, prevent it from excessive displacement, and improve the safety and reliability of the ejection assembly 2.

[0023] The outer surface of the connecting block 35 is slidably connected to the inner wall of the long slot 34 , and the connecting block 35 slides in the long slot 34 to ensure its stability and directionality during the displacement process.

The cooperation between the long strip 31 and the guide rail groove 32 further improves the stability and accuracy of the mobile frame 6 during the shifting process, preventing the mobile frame 6 from shaking or offsetting.

[0025] Working principle: First, place the wheel hub bearing to be assembled on the assembly seat 5, and perform the assembly operation through the assembler body 4.

[0026] Next, when the hub bearing is assembled, the ejection assembly 2 is started, and the output end of the telescopic gas rod 26 pushes the cross bar 28 to slide in the limiting groove 27 on the inner wall of one side of the guide groove 23.

[0027] The cross bar 28 drives the second hinge seat 25 to slide on the lower inner wall of the guide groove 23, and the second hinge seat 25 moves to cooperate with the first connecting rod 22 and the second connecting rod 24 and the first hinge seat 29 and the third hinge seat 21 to push the connecting frame 7 up.

[0028] At this time, the pneumatic clamping rod 8 on the connecting frame 7 will clamp the assembled wheel hub bearing and push it out from the assembly seat 5.

[0029] When the shift mechanism 3 is started, the output end of the motor 37 drives the worm 38 to rotate, and the worm 38 engages with the worm wheel 39 for transmission. The worm wheel 39 is fixedly sleeved on the rotating rod 301, thereby driving the rotating rod 301 to rotate.

[0030] The rotation of the rotating rod 301 drives the screw rod 302 to rotate, and the rotation of the screw rod 302 causes the connecting block 35 to drive the moving frame 6 to move.

[0031] At the same time, the long strip 31 and the guide rail groove 32 cooperate to guide the moving direction of the movable frame 6.

[0032] The ejection assembly 2 provided on the moving frame 6 and the connecting frame 7 and the wheel hub bearing on the ejection assembly 2 move together with the moving frame 6 to transport the wheel hub bearing to a designated position.

[0033] When the wheel hub bearing is transported to the designated position, the ejection assembly 2 and the shift mechanism 3 are reset in sequence, and the next wheel hub bearing assembly, blanking and ejection operation is ready.

[0034] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
