[0002] The automotive CVJ is the core transmission device connecting the transmission and wheels. Through the coordinated action of the inner and outer CVJs, it maintains stable power transmission during driving and steering. Its structure includes components such as a bell housing, a three-pronged bearing / steel balls, and a dust cover. During assembly of the inner CVJ, components such as the retaining ring and the blind cover must be installed. The typical steps are as follows: first, orient the inner CVJ with the large end facing upward, apply glue, then press the blind cover into the inner CVJ.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] For example 1, please refer to Figures 1 to 8 A machine for pressing and assembling an inner ball cage with a glue-dispensing retainer ring and a blind cover includes a frame 1, a first cylinder 2 and a glue-dispensing mechanism provided on the frame 1, a pressure head 3 provided on the piston rod of the first cylinder 2, the glue-dispensing mechanism including a fixing seat 4, a cavity 5 and a flow channel 7 provided in the fixing seat 4, a piston 6 provided in the cavity 5, a glue inlet 701 provided at one end of the flow channel 7, a glue outlet 702 provided at the other end of the flow channel 7, a glue outlet pipe 8 provided at the glue outlet 702, a flow direction adjustment seat 35 provided in the flow direction adjustment seat 35, and a U-shaped guide groove 36 provided on the flow direction adjustment seat 35;

[0036] The fixing seat 4 is provided with a glue head cleaning mechanism, and the glue head cleaning mechanism includes a first electric push rod 9, which is located at one end of the flow channel 7 close to the glue outlet 702, and a cleaning head 10 is provided on the piston rod of the first electric push rod 9.

[0037] The glue outlet pipe 8 is provided with a glue outlet head 11 , and one end of the glue outlet pipe 8 close to the glue outlet head 11 is in a cone shape. A dredging mechanism is provided on the lower side of the glue outlet head 11 .

[0038] The dredging mechanism includes a third electric push rod 14 , and a dredging rod 15 is provided on the piston rod of the third electric push rod 14 , and a scraper 16 is provided on one side of the dredging rod 15 .

[0039] The glue outlet pipe 8 and the glue outlet head 11 are dredged by setting a glue head cleaning mechanism and a dredging mechanism. The glue head cleaning mechanism is located inside the fixing seat 4, which includes a cavity 5. The cavity 5 is connected to the flow channel 7 through the branch channel 34. A flow direction regulating seat 35 is also provided in the flow channel 7. The piston 6 can be pushed to move in the cavity 5 by the third cylinder 32. When the piston 6 moves in the direction away from the flow channel 7, the U-shaped guide groove 36 is in a state where one end is connected to the branch channel 34 and the other end is connected to the glue inlet 701. At this time, the flow direction regulating seat 35 plays a role in The glue outlet 702 is in a closed state. At this time, as the piston 6 moves, the interior of the cavity 5 is in a negative pressure state. The glue inlet 701 is connected to the glue storage barrel. The glue in the glue storage barrel enters the cavity 5 through the U-shaped guide groove 36 and the branch channel 34. Then, the position of the flow direction adjustment seat 35 is adjusted to make the U-shaped guide groove 36 and the glue inlet 701 staggered. At this time, the flow direction adjustment seat 35 plays a role in closing the glue inlet 701. The piston 6 returns to its original position, and the glue in the cavity 5 flows out through the glue outlet 702, the glue outlet pipe 8, and the glue outlet head 11;

[0040] When the glue discharging head 11 is blocked, the dredging mechanism first moves to a position opposite to the glue discharging head 11, and then the third electric push rod 14 works. Driven by the third electric push rod 14, the dredging rod 15 is inserted into the glue discharging head 11, and then the interior of the glue discharging head 11 is dredged. Then the dredging rod 15 returns to its original position, and then the first electric push rod 9 works. Pushed by the first electric push rod 9, the cleaning head 10 enters the glue discharging pipe 8 through the glue outlet 702, and dredges the glue discharging pipe 8 from the inside. Then the cleaning head 10 returns to its original position, and the dredging rod 15 and the cleaning head 10 work alternately until the dredging is completed.

[0041] In this technical solution, there are two ways to install the dredging mechanism. One is to fix it directly on the frame 1 on the lower side of the fixed seat 4. The distance between the dredging rod 15 and the glue head 11 is large. During operation, the workpiece is placed in the gap between the dredging rod 15 and the glue head 11 by a robot for dispensing glue. When cleaning is required, just move the workpiece away. The other is to slide horizontally on the frame 1. Under normal circumstances, the dredging rod 15 and the glue head 11 are staggered. When cleaning is required, the position of the dredging mechanism is adjusted by a cylinder or other actuator to align the dredging rod 15 with the glue head 11, and then the dredging rod 15 is pushed by the third electric push rod 14.

[0042] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 The dredging mechanism includes a second electric push rod 12, and a cleaning brush head 13 is provided on the piston rod of the second electric push rod 12.

[0043] The present technical solution also discloses a dredging mechanism, which includes a cleaning brush head 13. Under the push of the second electric push rod 12, the cleaning brush head 13 can dredge the glue discharging head 11. Compared with the dredging mechanism in Example 1, the cleaning brush head 13 in this embodiment adopts a method of brushing off the blockage to dredge, while the dredging mechanism in Example 1 adopts a method of scraping off the blockage through the dredging rod 15 to dredge.

[0044] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 , a plurality of extension rods 17 are provided at one end of the glue discharge pipe 8 close to the glue discharge head 11, and the extension rods 17 are arranged on the glue discharge pipe 8 in a ring shape and equidistantly, and one end of the extension rod 17 is elastically connected to the glue discharge pipe 8 through a first spring 18, and one end of the extension rod 17 extends to the interior of the glue discharge pipe 8;

[0045] A ring-shaped adjustment seat 19 is provided on the outer side of the rubber outlet pipe 8 . The cross section of the adjustment seat 19 is triangular. The adjustment seat 19 is elastically connected to the rubber outlet pipe 8 via a second spring 20 .

[0046] The cleaning head 10 is disc-shaped, and a plurality of movable rake teeth 21 are provided at the lower end of the cleaning head 10 . The rake teeth 21 are elastically connected to the cleaning head 10 via rebound springs 22 , and triangular protrusions 24 are provided on the rake teeth 21 .

[0047] A plurality of first adjustment rods 23 are provided inside the cleaning head 10 . One end of the first adjustment rod 23 abuts against the triangular protrusion 24 , and the other end of the first adjustment rod 23 is provided with an inclined surface.

[0048] Under normal circumstances, the diameter of the glue head 11 at the end is smaller than the glue pipe 8 or the glue outlet 702. In order to reduce the residual glue, a tapered transition area is generally set at the connection between the glue head 11 and the glue pipe 8. However, when dredging, neither the cleaning head 10 nor the dredging rod 15 can clean this transition area, so blockages are likely to accumulate in this area. For this reason, the present technical solution sets a number of extension rods 17 in this transition area. The extension rods 17 are elastically connected to the glue pipe 8. An adjustment seat 19 for uniformly adjusting all the extension rods 17 is provided on the outside of the glue pipe 8. The middle part of the adjustment seat 19 is provided with a The conical notch, when the dredging rod 15 moves upward, after reaching a certain height, the scraper 16 conflicts with the bottom end of the adjustment seat 19, and the adjustment seat 19 overcomes the resistance of the second spring 20 and moves upward under the push of the scraper 16. The inclined surface inside the adjustment seat 19 conflicts with the outer end of the extension rod 17. Under the push of the adjustment seat 19, the extension rod 17 moves toward the inside of the rubber outlet hose 8. In this way, when dredging, after the dredging rod 15 is inserted, it is kept stationary, so that the extension rod 17 is in a protruding state. Then when the cleaning head 10 moves again, the blockage can be pushed toward the extension rod 17. The extension rod 17 can play a role in breaking the blockage and facilitate the discharge of the blockage.

[0049] In order to further improve the cleaning effect, a number of rake teeth 21 are provided on the cleaning head 10. In order to reduce the residue of glue, under normal circumstances, the rake teeth 21 are in a state of being retracted into the cleaning head 10. A card slot that fits the dredging rod 15 is provided in the middle of the cleaning head 10. The dredging rod 15 will be inserted into the card slot when it moves. During the insertion process, the dredging rod 15 conflicts with the first adjusting rod 23, and the first adjusting rod 23 conflicts with the triangular protrusion 24. Driven by the triangular protrusion 24, the rake teeth 21 move down and extend out of the cleaning head 10. The dredging rod 15 is rotatably connected to the piston rod of the third electric push rod 14. The piston rod of the third electric push rod 14 is also provided with a drive motor 38 for driving the dredging rod 15 to rotate. In this way, when the dredging rod 15 and the cleaning head 10 are plugged together, the dredging rod 15 and the cleaning head 10 can rotate synchronously under the drive of the drive motor 38, and then cooperate with the extension rod 17 and the rake teeth 21 to further improve the crushing effect of the blockage.

[0050] The driving motor 38 can be connected to the dredging rod 15 through a gear, or can be connected to the dredging rod 15 through a belt.

[0051] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8The dredging rod 15 is prismatic, and a fixing groove 25 is provided inside the dredging rod 15. A second adjusting rod 26 is provided in the fixing groove 25. The second adjusting rod 26 is elastically connected to the dredging rod 15 through a reset spring 27, and a conical protrusion 28 is provided on the second adjusting rod 26. A stirring rod 29 is symmetrically provided on the dredging rod 15, and the stirring rod 29 is slidably connected to the dredging rod 15.

[0052] A support frame 30 is provided on one side of the frame 1, and a second cylinder 31 is provided on the support frame 30 for pushing the fixed seat 4 to rise and fall, a third cylinder 32 is provided on the fixed seat 4, and the piston rod of the third cylinder 32 is fixedly connected to the piston 6, a flushing port 33 connected to the flow channel 7 is provided on one side of the fixed seat 4, a branch channel 34 for connecting the flow channel 7 and the cavity 5 is opened on the fixed seat 4, and a hydraulic cylinder 37 for pushing the flow direction adjustment seat 35 to move is provided on one side of the fixed seat 4.

[0053] In order to improve the cleaning effect, a movable second adjusting rod 26 is provided at the dredging rod 15. When the dredging rod 15 collides with the cleaning head 10, the second adjusting rod 26 is retracted into the dredging rod 15 under the influence of the cleaning head 10 and collides with the stirring rod 29. The stirring rod 29 extends out of the dredging rod 15. As the dredging rod 15 rotates, the stirring rod 29 cooperates with the rake teeth 21 and the extension rod 17 to further improve the crushing effect of the blockage, making it easier to discharge the blockage.

[0054] The dredging rod 15 can drive the scraper 16 to rotate during the rotation process, and the scraper 16 can scrape off the residue on the outside of the glue head 11. In order to prevent the scraper 16 from colliding with the glue discharge pipe 8 in the process of pushing the adjustment seat 19 to rise, an extended protrusion is provided on the top of the scraper 16, and the protrusion is used to conflict with the adjustment seat 19.

[0055] The position of the fixing seat 4 can be adjusted. When the workpiece reaches the bottom of the fixing seat 4, the position of the fixing seat 4 is adjusted by the second cylinder 31 so that the glue head 11 is close to the workpiece to facilitate glue dispensing. By setting a flushing port 33, the cleaning liquid can be sent into the cavity 5 or the flow channel 7 through the flushing port 33 to clean it. When dispensing glue, the flushing port 33 is closed, and a one-way valve can also be set at the flushing port 33 to prevent the glue from flowing back.

[0056] An inner ball cage forming process of an inner ball cage glue-dotting retaining ring blind cover press-fitting machine comprises the following steps:

[0057] S1. First, the inner ball cage body is transported by a conveyor belt. When it reaches the designated location, the robot takes the inner ball cage body and places it in the dispensing station. The inner ball cage body is glued by the dispensing machine.

[0058] S2. The robot takes the inner ball cage body after the dispensing treatment and places it in the press-fitting station. The pressing head 3 presses the blind cover into the inner ball cage body.

[0059] S3. The inner cage body after press-fitting is taken by a robot and placed on the retaining ring installation station. During this process, the upper and lower positions of the inner cage body are turned, and then the retaining ring is press-fitted onto the inner cage body by a press.

[0060] S4. Carry out appearance inspection and dimension inspection on the assembled workpieces, perform performance test on them after the inspection is completed, and package them after passing the test.

[0061] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
