[0038] The working principle of this embodiment is as follows:

[0039] In order to install the positioning pin 5 in the two mounting holes 14 on the top of the bearing bracket 3 and to fix the bearing bracket 3 to the bottom of the semi-circular buckle 17 by bolt body 9, firstly, insert the positioning hole 13 on the top of the bearing bracket 3 into the positioning rod 24 on the limiting frame 21, place the bottom of the bearing bracket 3 and the connected semi-circular buckle 17 in the limiting seat 22, start the cylinder 23, and the cylinder 23 limits the connection between the bearing bracket 3 and the semi-circular buckle 17.

[0040] When it is necessary to install the positioning pin 5 into the mounting hole 14 at the bottom of the bearing bracket 3, firstly, the vibrating feeder 71 is activated, which transports the positioning pin 5 along the conveying channel 72 to the mounting base 73. Then, cylinder 2 743 is activated, which pushes the push plate 741 to slide on the mounting base 73, pushing the positioning pin 5 transported to the mounting base 73 to the top of the through groove 742. Then, cylinder 3 744 is activated, which drives its piston rod to move upward, thereby pushing the positioning pin 5 on the through groove 742 upward. Finally, the pneumatic gripper 61 is activated, which clamps the positioning pin 5. The cylinder is then turned to move downwards from the pneumatic pressure head 41, and cylinder 62 is activated. Cylinder 62 drives the pneumatic gripper 61 to move upwards, thereby installing the positioning pin 5 on the pneumatic gripper 61 onto the pneumatic pressure head 41.

[0041] When it is necessary to install the bolt body 9 into the fixing hole 16 at the top of the bearing bracket 3 and the semi-circular buckle 17 to achieve a fixed connection between the bearing bracket 3 and the semi-circular buckle 17, the electric pressure head 811 is activated. The electric pressure head 811 passes through the mounting bracket 812 and presses the screw body 91 into the corresponding two fixing holes 16. Then, the motor 823 and the cylinder 824 are activated. The cylinder 824 drives the wrench 822 and the motor 823 to move forward along the guide rail 11.
