This structure supplies power to the entire press-fitting machine via an electrical box. The turntable structure on the frame starts intermittently. Each intermittent start places an installation fixture below the pressing equipment. Before each intermittent start, the pressing equipment starts once to press and secure the bearing and hub within the installation fixture. After pressing, the turntable rotates with the gaps in its rotation. When it reaches the side of the finished product pick-up and drop-off structure, a dual-axis lifter is activated to remove the pressed hub and bearing and place them onto the unloading slide, completing the installation of one caster. The bearing and hub loading process in this technical solution can be fully automatic before reaching the installation fixture, utilizing an external bearing vibratory feeder or a hub lift.

[0023] The turntable structure 2 described in this invention includes a rotation drive 21 mounted on a frame 1, and a turntable body 22 is mounted on the rotating core on the upper side of the rotation drive 21. The rotation drive uses a servo motor to drive the turntable body to rotate counterclockwise intermittently.

[0024] The installation fixture 3 of this utility model includes a tray 31 arranged around the turntable body 22 for supporting the wheel hub. A cavity 32 is provided in the center of the tray 31, and a positioning post 33 for inserting a bearing is provided in the center of the cavity 32. The tray supports the wheel hub for stable placement, and the cavity is used to insert the bearing. When inserting the bearing, the bearing must be inserted into the positioning post. After inserting the bearing, there is still some space in the cavity for inserting the center hole of the wheel hub. After pressing by a stamping device, the bearing will be embedded into the center hole of the wheel hub, completing the installation. The replaceable structure 4 of this utility model includes several through holes 41 arranged around the turntable body 22. A bottom mounting plate 42 is provided below the through holes 41, and a detachable post 43 connected to the bottom mounting plate 42 is provided inside the through holes 41. The tray 31 is fixed to the top of the detachable post 43. After the bottom mounting plate is installed with screws at the bottom of the perforation, the removable column is inserted into the hole of the bottom mounting plate from above the perforation. Since the removable column is connected to the tray, the dimensions of the tray, cavity, and positioning column can be changed for replacement.

The push rod drive drives the stamping head to move linearly up and down, and the limiting guide sleeve assists in limiting the linear movement of the stamping head. The push rod drive uses an electric push rod device.

[0026] The dual-axis lifting device 7 described in this utility model includes a horizontal rail 71 and a vertical rail 72. A horizontal drive push rod 73 is provided on one side of the horizontal rail 71 to move the vertical rail 72 within it. A vertical drive push rod 74 is provided on one side of the vertical rail 72 to lift and lower the finished product handling structure 8. The horizontal drive push rod of the horizontal rail can drive the vertical rail to move horizontally, and the vertical drive push rod of the vertical rail can drive the cylinder to move up and down. The combination of these two mechanisms allows for multi-directional adjustment of the cylinder position.

[0027] The finished product picking and placing structure 8 described in this utility model includes a cylinder 81 fixed to the movable end of a vertical drive push rod 74. A picking sleeve 82, capable of lifting the wheel hub upwards, is fixedly disposed on the lower side of the cylinder 81.
