6. The press-fitting machine for driving and driven wheels and bearings as described in claim 5, characterized in that, The main moving base includes a main base plate, a main cover frame, a main pressure plate, and a main support column. The main base plate is vertically movable and assembled with the main moving rail. The main cover frame is assembled with the main base plate, and the main cover frame is fitted with the main pressure plate. The main cover frame is used for assembling the main baffle. The main bearing plate, the main pressure plate, and the main base plate are sequentially stacked from top to bottom. The main pressure plate is used to bear the downward pressure transmitted by the main bearing plate. The lower part of the main support column is fixed, and the upper part of the main support column extends through the main base plate and the main cover frame to embed the main pressure plate. The main support column and the main pressure plate are arranged in abutment at the middle.

7. The press-fitting machine for driving and driven wheels and bearings as described in claim 5, characterized in that, The main moving structure includes a main initial server and a main final server, which are arranged at intervals along the extension direction of the main moving track. The main initial servo and the main final servo are respectively used to detect the position of the main moving seat. The main initial servo is arranged in a corresponding manner to the initial position, and the main final servo is arranged in a corresponding manner to the pressing position.

8. The press-fitting machine for driving and driven wheels and bearings as described in claim 3, characterized in that, The main press-fitting structure includes a main cylinder and a main frame module. The main cylinder is used to provide downward pressure. The main frame module includes a main pull plate, a main middle plate, and a head fastener. The main pull plate, the main middle plate, and the head fastener are arranged sequentially from top to bottom. The main cylinder and the main pull plate are arranged vertically. The head fastener is used to assemble the main press head.

9. The press-fitting machine for driving and driven wheels and bearings as described in any one of claims 1-3, characterized in that, The housing component includes a mounting head for mounting a bearing component, and the driven wheel is fitted with the bearing component. The driven assembly includes a fixed seat for mounting the bearing component, which is arranged vertically to the mounting head. The fixed seat is used to position the bearing component and is embedded in the fixed seat. The lower part of the fixed post is aligned with the fixed seat, and the upper part of the fixed post extends upward. The driven structure is used to press down the driven wheel until the driven wheel and the bearing component are in a press-fit arrangement.

10. The press-fitting machine for driving and driven wheels and bearings as described in claim 9, characterized in that, The press-fit structure includes a press head, which includes a press base and three press blocks. The three press blocks are arranged in a triangular arrangement and are mounted on the press base. The driven wheel has a wheel groove and a groove ring wall. The wheel groove is hollow and the groove ring wall surrounds the wheel groove. The wheel groove is used for embedding each of the press blocks, and the groove ring wall is used to flatly abut against the press base. The press base has a seat channel for embedding a fixed post.
