AI Technical Summary
During the pressing process of fixed joints of the vehicle drive shaft assembly, the rotation operation of the solid shaft and fixed joints is carried out purely manually, resulting in the inability to pre-install, wasting time, affecting assembly efficiency, and may cause people to shut down and increase the burden on staff.
A solid shaft pressing machine is designed, equipped with a pre-installed rotation mechanism, including a bottom box, a rotating frame and a pre-installed frame. The pre-installation and automatic push of the solid shaft and fixed sections to the pressing position through structures such as hydraulic rods and snaps.
It realizes batch pre-installation of real shafts and fixed joints, improves the assembly efficiency of the drive shaft assembly, reduces manual operation time, avoids the situation of human shutdown, and simplifies subsequent maintenance.

2. The automobile drive shaft assembly assembly equipment according to claim 1, characterized in that: A plurality of sliding blocks (13) capable of sliding in a circular track are arranged in the bottom box (2), one side of the sliding block (13) extends outside the bottom box (2) and is fixedly connected to the main frame (11) of the pre-installed frame, a first hydraulic rod (5) is fixedly installed in the bottom box (2), and a buckle (6) for clamping with the sliding block (13) is arranged on the output rod of the first hydraulic rod (5); In this way, when each pre-installed frame moves to the buckle (6), it is engaged with the buckle (6), and the first hydraulic rod (5) can push and pull the pre-installed frame and the fixed section and the real shaft placed on the pre-installed frame through the buckle (6), thereby completing the work of placing the pre-installed real shaft and the fixed section on the frame and removing it.
3. The automobile drive shaft assembly assembly equipment according to claim 2, characterized in that: The bottom of the buckle (6) extends outside the bottom box (2) and is fixedly mounted with a second hydraulic rod (8); the bottom of the sub-frame (12) is L-shaped and corresponds to the output rod of the second hydraulic rod (8), thereby completing the lowering and placement of the real shaft and the fixed section without affecting the normal extension and retraction of the pre-installed frame.
4. The automobile drive shaft assembly assembly equipment according to claim 3, characterized in that: A retractable first extension bar (7) is arranged in the bottom box (2), and one end of the first extension bar (7) is connected to the buckle (6) and the second hydraulic rod (8), thereby improving the stability of the second hydraulic rod (8) without affecting the normal retraction of the second hydraulic rod (8).
5. The automobile drive shaft assembly assembly equipment according to claim 2, characterized in that: An annular slide rail (14) is arranged in the bottom box (2), and a pulley is arranged at the bottom of the slide block (13), wherein the pulley extends into the annular slide rail (14) and is slidably connected to the annular slide rail (14); In this way, when the rotating frame (4) drives the plurality of pre-installed frames to rotate, the pre-installed frames can be stably maintained in the current state and will not be extended prematurely due to inertia.
6. The automobile drive shaft assembly assembly equipment according to claim 1, characterized in that: The pre-installed frame is provided with a reverse thrust mechanism, the reverse thrust mechanism comprising two support blocks arranged on the main frame (11), the two support blocks being provided with positioning rods, the positioning rods being provided with a sliding sleeve having a first spring and a connecting block, the main frame (11) being provided with a long sliding hole, one side of the connecting block passing through the long sliding hole and being fixedly connected to the auxiliary frame (12), so that the auxiliary frame (12) can automatically rise and reset under the push of the first spring after descending.
7. The automobile drive shaft assembly assembly equipment according to claim 1, characterized in that: An articulated frame is provided on the sub-frame (12), the fixed section limiting bucket (15) is rotatably connected to the articulated frame, and the center of gravity of the fixed section limiting bucket (15) is located at the bottom; In this way, after the fixed section is pressed and installed, the drive shaft assembly only needs to be separated from the magnet (17) on the real shaft limiting sleeve (16), and the drive shaft assembly can be reversed and fall off by itself. After the drive shaft assembly falls off, the fixed section limiting bucket (15) can be reset by itself.
8. The automobile drive shaft assembly assembly equipment according to claim 1, characterized in that: The reset ejection mechanism comprises a sleeve (19) arranged on the real shaft limiting sleeve (16), a push rod (20) is slidably mounted in the sleeve (19), one end of the push rod (20) is in contact with the cam ring (18), two abutment blocks (21) are arranged on the push rod (20), the two abutment blocks (21) both extend outside the sleeve (19) and are slidably connected to the sleeve (19), and a second spring (22) is sleeved on the sleeve (19) and abuts against the two abutment blocks (21); As a result, when the push rod (20) follows the pre-installed frame to move to the protruding position of the cam ring (18), it will squeeze the second spring (22) and push the real shaft adsorbed by the magnet (17) out of the real shaft limiting sleeve (16), so that the drive shaft assembly that loses the adsorption of the magnet (17) completes the inversion and detaches from the pre-installed frame.
