The power of the engine is transmitted to the wheel through the differential, the movable end section, the intermediate shaft, the fixed end section and the wheel hub, thereby driving the wheel to rotate. In the assembly process of high-end drive shafts, the uniform distribution of grease in the fixed end section and the movable end section (that is, the grease is between the moving parts) is very important, which will directly affect the performance of the drive shaft. The OEM requires that the drive shaft be 100% evenly distributed with grease after assembly and before packaging. If the grease cannot be evenly distributed before the vehicle is off the line, the user will directly run it at high speed after the vehicle is sold, which will cause the parts inside the fixed end section and the movable end section to wear more in a short period of time, which is not conducive to the durability of the drive shaft and user dissatisfaction. In the past, the uniform distribution of transmission shaft grease was done by manual clamping on the functional test bench, which was not only labor-intensive but also took a long time (10 minutes); or the fixed end section was manually swung and the movable end section was pulled and pushed, which was labor-intensive and could not guarantee the quality 100% due to human factors. Therefore, a machine that can automatically and efficiently distribute the transmission shaft grease online is urgently needed at the assembly site. Summary of the invention

[0005] The workbench is provided with a long groove and a T-shaped guide groove, and a slide plate is provided on the long groove and the T-shaped guide groove. The slide plate is fixedly connected to the T-shaped guide groove by screws, and the bottom of the slide plate is fixedly connected to the connecting plate B.

[0019] The working process of the present invention is as follows: first, the movable end section of the transmission shaft is clamped in the clamping jaw A14 by manual setting, and then the center of the movable end section is adjusted by the ruler A6 and the electric cylinder A9 so that the center of the movable end section coincides with the center of the rotating shaft C4, and the controller records the position of the box A11 at this time (this position is defined as the original position of the box A); the fixed end section of the transmission shaft is clamped in the clamping jaw B15, and then the center of the fixed end section is adjusted by the ruler B23 and the electric cylinder B20 so that the center of the fixed end section coincides with the center of the rotating shaft D24, and the controller records the position of the box B18 at this time (this position is defined as the original position of the box B), the clamping jaws A14 and B15 release the movable end section and the fixed end section, and remove the transmission shaft. For transmission shafts of different lengths, loosen the screw 41, turn the hand wheel 37, and drive the slide plate 25 to move to the desired position through the spiral movement between the nut in the nut seat 34 connected to the lead screw 35 and the slide plate 25. By pressing the start button 46, the manipulator moves the transmission shaft to between the clamp A14 and the clamp B15. Synchronously, the electric cylinder B20 drives the box B18 and the rotating shaft B17, the clamping cylinder B16 and the clamp B15 thereon to withdraw to the right and rear along the double guide rail B22 by a safe distance greater than the length of the handle 53 of the fixed end section of the transmission shaft. The telescopic ends of the lifting cylinders A30 and B29 drive the V-blocks A31 and B28 to lift through the clearance opening 43. The manipulator releases the transmission shaft and places the transmission shaft on the V-blocks A31 and B28. At this time, the axis of the transmission shaft is consistent with the center line of the rotating shaft A12 and the rotating shaft B17. When the sensors A32 and B42 detect the presence of a workpiece, the electric cylinder B20 drives the box B18 and the rotating shaft B17, the clamping cylinder B16 and the clamp B15 thereon to move to the original position to the left along the double guide rail B22. The handle of the fixed end section 53 is just located in the clamping jaw B15, and the electric cylinder A9 drives the box A11 and the rotating shaft A12, the clamping cylinder A13, and the clamping jaw A14 to move to the right along the double guide rail A7 to a set distance. The purpose is to make the clamping jaw A14 contain the entire moving end section of the transmission shaft and close to the corresponding end face of the moving end section, and on the other hand, make the positioning surface 51 of the fixed end section of the transmission shaft close to the left end face of the clamping jaw B15, and the clamping cylinder A 13 drives the clamping claw A14 to clamp the movable end section, the clamping cylinder B16 drives the clamping claw B15 to clamp the handle 53 of the fixed end section, the telescopic ends of the lifting cylinder A30 and the lifting cylinder B29 drive the V-block A31 and the V-block B28 to return to their original positions through the clearance opening 43, and the electric cylinder A9 drives the box A11 and the rotating shaft A12 thereon, the clamping cylinder A13, the clamping claw A14 and the movable end section to return to their original positions to the left along the double guide rail A7.The rotating end of the servo motor C2 drives the mobile end section of the transmission shaft to swing back and forth around the center of the mobile end section according to the set swing angle range, swing speed, and swing frequency through the rotating shaft C4, turntable A8, box A11, rotating shaft A12, clamping cylinder A13, and clamping claw A14. Synchronously, the rotating end of the servo motor D27 drives the fixed end section of the transmission shaft to swing back and forth around the center of the fixed end section according to the set swing angle range, swing speed, and swing frequency through the rotating shaft D24, turntable B21, box B18, rotating shaft B17, clamping cylinder B16, and clamping claw B15. Synchronously, the telescopic end of the electric cylinder A9 drives the box A11, rotating shaft A12, clamping cylinder A13, and clamping claw A14 to drive the mobile end section of the transmission shaft to reciprocate along the double guide rail A7 according to the set stroke, movement speed, and frequency. Synchronously, the rotating end of the servo motor A10 drives the mobile end section of the transmission shaft to swing back and forth along the double guide rail A7 according to the set stroke, movement speed, and frequency through the rotating shaft A12, clamping cylinder A13, and clamping jaw A14 drive the movable end section of the transmission shaft to rotate at a set speed. Synchronously, the rotating end of the servo motor B19 applies torque to the fixed end section of the transmission shaft according to a set torque (this torque is usually a small load torque) through the rotating shaft B17, clamping cylinder B16, and clamping jaw B15. When the set running time is reached, the servo motor A10, servo motor B19, servo motor C2, and servo motor D27 stop rotating, the electric cylinder A9 stops reciprocating motion, and the telescopic ends of the lifting cylinders A30 and B29 drive the V-block A31 and the V-block B28 to lift through the clearance opening 43. The electric cylinder A9 drives the box A11 and the rotating shaft A12, clamping cylinder A13, and clamping jaw A14 thereon to move to the right to a set distance along the double guide rail A7, and the telescopic end of the clamping cylinder A13 drives the clamping jaw A14 to loosen and move.

[0020] The electric cylinder A9 drives the box A11 and the rotating shaft A12, clamping cylinder A13 and clamping claw A14 along the double guide rail A7 to retreat to the original position to the left. The telescopic end of the clamping cylinder B16 drives the clamping claw B15 to loosen the fixed end section.
