Technical Field
[0001] The utility model relates to an automatic running and uniform distribution device, in particular to a grease uniform distribution machine inside two end joints of a transmission shaft. Background Art
[0002] The constant velocity universal joint drive shaft of a car is composed of a fixed end joint, an intermediate shaft and a movable end joint. Among them, the fixed end joint is directly connected to the hub of the car wheel, and the movable end joint is directly connected to the differential of the engine. The power of the engine is transmitted to the wheel through the differential, the movable end joint, the intermediate shaft, the fixed end joint and the hub, so as to drive the wheel to rotate. During the assembly process of high-end drive shafts, the uniform distribution of grease in the fixed end joint and the movable end joint (that is, the grease is between each moving part) is very important, which will directly affect the performance of the drive shaft. The main engine factory requires that 100% of the grease be uniformly distributed after the drive shaft is assembled and before it is packed in a box. If the grease cannot be uniformly distributed before leaving the production line, when the vehicle is sold and the user runs at high speed directly, it will cause the parts inside the fixed end joint and the movable end joint to be severely worn in a short period, which is not conducive to the durability life of the drive shaft and will lead to user dissatisfaction. In the past, the uniform distribution of drive shaft grease was carried out manually on a functional test bench, which not only had a high labor intensity, but also had a long cycle time (10 minutes); or the fixed end joint was manually swayed and the movable end joint was pulled and pushed, which had a high labor intensity, and due to human factors, the quality could not be guaranteed 100%. Therefore, there is an urgent need for a machine on the assembly site that can automatically and efficiently distribute the drive shaft grease online. Summary of the Invention

[0019] The working process of the utility model 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), and the clamping jaws A14 and B15 loosen 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.

The transmission shaft falls on the V-shaped block A31 and the V-shaped block B28. The robot takes the transmission shaft away, and then puts the next transmission shaft to be greased and enters the next cycle...
