[0002] The ball cage of a drive shaft generally includes structures such as a bell housing, a cage, a spider, steel balls, a rubber boot, and a drive shaft. When assembling the ball cage of the drive shaft, the assembly of the steel balls into the bell housing, cage, and spider mainly relies on manual operation, resulting in slow assembly efficiency.

[0003] Chinese Patent with the authorization announcement number CN113478198B discloses a steel ball assembly device for a ball cage coupling. This assembly device for the steel balls of the ball cage coupling has a compact structure and ingenious design, and can mechanize the assembly and detection work of the steel balls of the ball cage coupling, solving the problems of "high labor intensity" and "low work efficiency" existing in the existing assembly methods of the steel balls of the ball cage coupling, and is particularly suitable for the needs of high-efficiency production in enterprises.

[0058] Embodiment 3

[0059] As Figures 4 to 6 shown in the figure, in the specific implementation manner, the first feeding mechanism includes a middle shaft 102. A push rod 103 is rotatably mounted at the bottom of the middle shaft 102. A backing plate 104 is rotatably mounted at one end of the push rod 103. The backing plate 104 is movably connected to the side of the lower support column 101. The feeding unit further includes a power mechanism. The power mechanism is used to drive the first feeding mechanism and the second feeding mechanism. The power mechanism includes a first electric cylinder 110 and a second electric cylinder 111. The first electric cylinder 110 and the second electric cylinder 111 are fixedly mounted on one side of the upper support column 100. The output end of the first electric cylinder 110 is fixedly connected to the middle shaft 102. In this setting, the first electric cylinder 110 works and drives the middle shaft 102 to descend. The middle shaft 102 drives the backing plate 104 to squeeze the inner wall of the star-shaped sleeve through the push rod 103, so that the star-shaped sleeve is captured by the first feeding mechanism.

[0060] As Figures 4 to 6 shown, further, the second feeding mechanism further includes a plug rod 107. A first pull rod 108 is rotatably installed on one side of the plug rod 107. One end of the first pull rod 108 is rotatably installed with a pull ring 109. The pull ring 109 is movably sleeved on the lower support column 101. The pull ring 109 is fixedly connected to the output end of the second electric cylinder 111. The second feeding mechanism further includes a limiting tube 106. The limiting tube 106 is fixedly connected to the frame plate 105. The plug rod 107 is movably inserted into the limiting tube 106 and the frame plate 105. In this setting, when the second electric cylinder 111 works to drive the pull ring 109 to move, the pull ring 109 drives the plug rod 107 to move through the first pull rod 108, so that the plug rod 107 extends into the side hole position of the cage.

[0061] As Figures 1 - 2 shown, further, the flexible assembly line of the modular constant velocity drive shaft assembly further includes a sliding device 500. An oil cylinder 501 is installed at the bottom of the sliding device 500. The output end of the oil cylinder 501 is fixedly connected to the rotating disc 212. The upper and lower ends of the rotating disc 212 are respectively rotatably connected to one side of the upper support plate 214 and the connecting plate 306 through connecting pieces. A ratchet mechanism is installed between the rotating disc 212 and the upper support plate 214. In this setting, the ratchet mechanism is used to limit the rotation direction of the assembly unit, so that it can only rotate along one rotation direction of the rotating disc 212.

[0062] Cylinders are installed on both sides of the bell housing for clamping the bell housing, and the bell housing, the star gear sleeve and the cage are all transported by a conveyor belt.

[0063] The implementation principle of the flexible assembly line of the modular constant velocity drive shaft assembly in this embodiment is as follows: During assembly, the sliding device 500 drives the feeding unit and the assembly unit to move as a whole. When moving to the conveyor belt where the star gear sleeve is transported, the oil cylinder 501 drives the feeding unit and the assembly unit to descend, so that the lower support column 101 extends into the central part of the star gear sleeve. At this time, the first electric cylinder 110 works and drives the middle shaft 102 to descend. The middle shaft 102 drives the backing plate 104 to squeeze the inner wall of the star gear sleeve through the push rod 103, so that the star gear sleeve is captured by the first feeding mechanism. After capturing the star gear sleeve, the sliding device 500 and the oil cylinder 501 work again to align the feeding unit with the cage, drive the star gear sleeve to be installed into the cage. At the same time, the second electric cylinder 111 works to drive the pull ring 109 to move. The pull ring 109 drives the plug rod 107 to move through the first pull rod 108, so that the plug rod 107 extends into the side hole position of the cage. At this time, the oil cylinder 501 contracts, so that the star gear sleeve and the cage are carried and moved until they are aligned with the bell housing. At the same time, the cylinders on both sides of the bell housing clamp the bell housing to keep the bell housing in a fixed state;

[0064] The oil cylinder 501 extends to install the star-shaped sleeve and the retaining frame into the bell-shaped housing, and at the same time, the second electric cylinder 111 is reset to reset the insertion rod 107. At this time, the power device 215 rotates to rotate the rotating column 201, and the rotating column 201 moves against the guide wheel 203 through the guide groove 202 to move the first connecting rod 206. The first connecting rod 206 drives the rotating rod 209 and the first blocking rod 211 to move by pushing the sliding frame 207. When the first blocking rod 211 is offset by the resistance of the groove 213, the first blocking rod 211 drives the rotating rod 209 to deflect and stretch the elastic rope 210 until the first blocking rod 211 is separated from the side wall of the groove 213. At this time, the elastic force of the elastic rope 210 drives the rotating rod 209 and the first blocking rod 211 to rotate and reset;

[0065] The rotating column 201 rotates while driving the rotating wheel 300 to rotate, and the rotating wheel 300 drives the rotating groove 301 to rotate. At this time, the second gear lever 302 slides in the rotating groove 301. When the rotating column 201 rotates half a circle, the guide wheel 203 abuts against the guide inclined surface 205 of the limiting ring 204 and moves to one side. At this time, the guide wheel 203 is located in the annular part of the guide groove 202. When the rotating column 201 continues to rotate, the guide wheel 203 remains stationary under the action of the limiting ring 204.

[0066] When the rotating column 201 rotates half a circle, the rotating wheel 300 rotates half a circle accordingly. At this time, the rotating groove 301 drives the second blocking rod 302 to move. The second blocking rod 302 drives the support shaft 304 to move by abutting against the second connecting rod 303, and then pushes the loading unit to deflect through the support frame 305. At this time, the loading unit drives the star-shaped sleeve and the retaining frame to deflect. The support shaft 304 moves and drives the installation shaft 307 to move. The installation shaft 307 drives the second mounting frame 403 to move through the second pull rod 406 and the protrusion 407, so that the placement tube 408 moves. When the placement tube 408 moves, the third blocking rod 409 abuts against the slide groove 413 and drives the rotating rod 412 to rotate, so that the railing 414 is opened. At this time, the steel ball enters the side hole position of the retaining frame and the star-shaped sleeve;

[0067] The power device 215 works in the reverse direction. At this time, the rotating column 201 and the rotating wheel 300 rotate in the reverse direction. The guide wheel 203 remains in the same position under the action of the limit ring 204. At the same time, the tension of the tension spring 308 acts on the support shaft 304, so that the support shaft 304 drives the feeding unit to reset. At this time, the star sleeve and the retaining frame are reset so that the steel ball can be installed in the bell housing.

[0068] When the rotating column 201 and the rotating wheel 300 rotate half a turn, the support shaft 304 drives the feeding unit to return to its original position completely. At this time, the rotation of the rotating wheel 300 causes the second stop lever 302 to slide in the rotating groove 301. At the same time, the rotating column 201 drives the guide wheel 203 to move and return under the action of the limiting ring 204, thereby driving the first connecting rod 206 to return. The first connecting rod 206 drives the first stop lever 211 to return through the sliding frame 207 and the rotating rod 209. The first stop lever 211 deflects under the action of the groove 213, and then drives the entire assembly unit to rotate so as to install other steel balls.
