Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] The core of this utility model is to provide a cover riveting device for the end section of a drive shaft, which can realize operations such as automatic pressing of inner and outer covers with AC sections, automatic grease injection of AC sections, steel ball detection of AC sections, and automatic edge rolling of inner covers with AC sections, effectively improving the production efficiency and processing quality of drive shafts, and effectively reducing the labor intensity of operators.

[0049] Please refer to Figures 1-11 .

[0050] This specific embodiment provides a cover riveting device for a drive shaft end section, including:

[0051] The pressing mechanism 1 includes an inner pressing head for pressing the inner cover 43 of the drive shaft 42, an outer pressing head for pressing the outer cover 44 of the drive shaft 42, a press 21 for driving the inner pressing head and the outer pressing head for pressing, and a switching device. The inner pressing head and the outer pressing head are both mounted on the switching device, which is used to move the inner pressing head or the outer pressing head to the pressing position of the pressing mechanism 1.

[0052] The detection mechanism 5 includes a detection head 34 for detecting whether there are steel balls in the AC section 45 of the drive shaft 42 and a first driving member for driving the detection head 34 to move in space. The detection head 34 is located at the moving end of the first driving member.

[0053] The grease injection mechanism 4 includes a grease injection head 31 for injecting grease into the AC section 45 and a second driving member for driving the grease injection head 31 to move spatially. The grease injection head 31 is located at the moving end of the second driving member.

[0054] The hemming device 2 includes a hemming member for automatically hemming the outer cover 44 onto the AC section 45 and a third driving member for driving the hemming member to move in space, with the hemming member located at the moving end of the third driving member.

[0055] The transfer mechanism 3 includes a gripper mechanism 11 for holding one end of the drive shaft 42, a transfer moving plate 12 for carrying the other end of the drive shaft 42, and a fourth driving member. The transfer moving plate 12 is located below the gripper mechanism 11. The moving ends of the gripper mechanism 11 and the fourth driving member are connected to each other so that the drive shaft 42 can switch between the pressing position and the rolling position of the rolling device 2.

[0056] The frame, pressing mechanism 1, detection mechanism 5, grease injection mechanism 4, hemming device 2, and transfer mechanism 3 are all mounted on the frame;

[0057] The control device, press 21, switching device, detection head 34, first drive unit, grease injection head 31, second drive unit, hemming part, third drive unit, gripper mechanism 11 and fourth drive unit are all connected to the control device.

[0058] It should be noted that, as Figure 8 As shown, the drive shaft 42 has an inner cover 43 and an outer cover 44 at its end, and a cavity can be formed between the inner cover 43 and the outer cover 44. The area within the cavity that does not contain the drive shaft 42 is the AC section 45, and a steel ball is provided inside the AC section 45. In actual application, the shape, structure, type, and position of the pressing mechanism 1, the detection mechanism 5, the grease injection mechanism 4, the edge rolling device 2, the transfer mechanism 3, the frame, and the control device can be determined according to the actual situation and requirements.

[0059] In one embodiment, such as Figure 4As shown, the pressing mechanism 1 also includes a pressing guide column 26 vertically mounted on the frame, a pressing fixing plate 24 mounted on the top of the pressing guide column 26, a pressing moving plate 25 slidably mounted on the outer periphery of the pressing guide column 26, and a press counterweight cylinder 23 for balancing the weight of the press head of the press 21.

[0060] The press 21 and the press counterweight cylinder 23 are both connected to the control device and are mounted on the press mounting plate 24. The press head of the press 21 is connected to the press mounting moving plate 25 through a linear bearing. The pull rod of the press counterweight cylinder 23 is connected to the press mounting moving plate 25. The switching device is mounted on the press mounting moving plate 25.

[0061] It should be noted that the press 21 can be configured as a servo motor, which serves as the power source for the pressing of both the inner and outer pressing heads. The servo motor can also display the displacement and pressure during pressing, allowing operators to accurately control the pressing process. The press counterweight cylinder 23 effectively balances the weight of the press head on the press 21. The press head of the press 21 is fixedly connected to the pressing moving plate 25 via a linear bearing, enabling the press head to move up and down along the pressing guide column 26, thereby driving the inner and outer pressing heads on the switching device to perform the pressing operation. Furthermore, the pressing fixing plate 24 is fixed to the frame using locating pins to ensure that the relative position remains unchanged after prolonged movement, guaranteeing the repeatability and accuracy of the mechanism.

[0062] In one embodiment, the switching device includes a switching cylinder 22 connected to a control device, a switching linear guide rail, and a switching block slidably disposed on the switching linear guide rail. The fixed end of the switching cylinder 22 and the switching linear guide rail are both located below the pressing plate 25. The switching end of the switching cylinder 22 is connected to the switching block, and an inner pressure head and an outer pressure head are disposed below the switching block. Therefore, by controlling the operation of the switching cylinder 22, the switching end extends and retracts, which drives the switching block to move laterally along the switching linear guide rail, thereby driving the inner and outer pressure heads to move laterally to the pressing position.

[0063] In one embodiment, such as Figure 7 As shown, the first driving component includes a detection lifting cylinder 32 for driving the detection head 34 to move up and down, a detection translation cylinder 33 for driving the detection lifting cylinder 32 to move horizontally, and a first support column 36. The first support column 36 is vertically mounted on the frame, and the detection head 34 is located at the moving end of the detection lifting cylinder 32. Both the detection lifting cylinder 32 and the detection translation cylinder 33 are connected to the control device.

[0064] The top of the first support column 36 is provided with a fixed end of the detection translation cylinder 33 and a first linear guide rail 35. The moving end of the detection translation cylinder 33 is connected to the detection lifting cylinder 32. The detection lifting cylinder 32 is slidably mounted on the first linear guide rail 35 by a slider.

[0065] Therefore, the detection lifting cylinder 32 can drive the detection head 34 to move up and down, and the detection translation cylinder 33 can drive the detection lifting cylinder 32 to move horizontally along the first linear guide rail 35, so as to drive the detection head 34 to move horizontally synchronously. Furthermore, the detection head 34 can be fixedly connected to a proximity switch to detect the presence or absence of a steel ball.

[0066] In one embodiment, such as Figure 6 As shown, the second driving component includes a grease lifting cylinder 27 for driving the grease injection head 31 to move up and down, a grease translation cylinder 28 for driving the grease lifting cylinder 27 to move horizontally, and a second support column 29. The second support column 29 is vertically mounted on the frame, and the grease injection head 31 is located at the moving end of the grease lifting cylinder 27. Both the grease lifting cylinder 27 and the grease translation cylinder 28 are connected to the control device.

[0067] The top of the second support column 29 is provided with a fixed end of the grease injection translation cylinder 28 and a second linear guide rail 30. The moving end of the grease injection translation cylinder 28 is connected to the grease injection lifting cylinder 27. The grease injection lifting cylinder 27 is slidably mounted on the second linear guide rail 30 via a slider.

[0068] Therefore, the grease injection lifting cylinder 27 can drive the grease injection head 31 to move up and down, and the grease injection translation cylinder 28 can drive the grease injection lifting cylinder 27 to move horizontally along the second linear guide rail 30, so as to drive the grease injection head 31 to move horizontally synchronously. The grease injection head 31 is used to inject grease into the AC section 45.

[0069] In one embodiment, the hemming component includes a three-jaw chuck 13 for hemming the outer cover 44 onto the AC section 45, a servo motor 16 for driving the three-jaw chuck 13 to rotate, a double-row angular contact ball bearing 14 for rotating the three-jaw chuck 13 around the center, and a limiting bearing 15 for hemming the outer cover 44 to the desired diameter. The rotating end of the servo motor 16 is connected to the three-jaw chuck 13, and the servo motor 16 is connected to a control device.

[0070] That is, the three-jaw chuck 13 is used to automatically roll and close the outer cover 44 onto the AC section 45. The double-row angular contact ball bearing 14 causes the closing mechanism of the three-jaw chuck 13 to rotate around the center, ensuring that the outer cover 44 is closed into a complete circle. The limit bearing 15 is used to limit the closing mechanism, ensuring that the outer cover 44 is closed to the diameter required by the drawing, and preventing dry friction with the closing mechanism. The servo motor 16 drives the three-jaw chuck to rotate through components such as the reducer, pulleys and synchronous belt, thereby realizing the rolling and closing operation of the outer cover 44.

[0071] In one embodiment, such as Figure 2As shown, the third driving component includes a pneumatic-hydraulic booster cylinder 17, a rolling guide post vertically mounted on the frame, a rolling fixing plate 20 mounted on the top of the rolling guide post, a rolling moving plate 19 slidably mounted on the outer periphery of the rolling guide post, and a rolling balancing cylinder 18 for balancing the gravity of the rolling component. Both the pneumatic-hydraulic booster cylinder 17 and the rolling balancing cylinder 18 are connected to the control device.

[0072] Both the gas-liquid booster cylinder 17 and the hemming balance cylinder 18 are mounted on the hemming fixing plate 20. The pressure head of the gas-liquid booster cylinder 17 is connected to the hemming moving plate 19 via a linear bearing. The pull rod of the hemming balance cylinder 18 is connected to the hemming moving plate 19. The hemming component is mounted on the hemming moving plate 19.

[0073] It should be noted that the pneumatic-hydraulic booster cylinder 17 has a greater boosting pressure than a regular cylinder. For example, the pneumatic booster cylinder 17 is pneumatically driven during the first half of its operation and hydraulically driven during the second half, allowing it to apply a greater boosting pressure. The pneumatic-hydraulic booster cylinder 17 is connected to the hemming component. The AC section 45 is fixed by raising and lowering the pneumatic-hydraulic booster cylinder 17. By pressing the height difference between the outer cover 44 and the hemming head of the three-jaw chuck 13, the hemming position of the three-jaw chuck 13 is ensured to be within the area required by the drawing. The hemming balancing cylinder 18 can balance the weight of the hemming component. The hemming moving plate 19 is connected to the hemming component, and the raising and lowering of the hemming component is achieved through the hemming guide post.

[0074] It should be further explained that the hemming operation of the hemming device 2 includes: 1. Controlling the pneumatic-hydraulic booster cylinder 17 to press down so that the three-jaw chuck 13 presses against the AC section 45; 2. Controlling the servo motor 16 to run so that the hemming head of the three-jaw chuck 13 rotates to perform the hemming operation; 3. Controlling the servo motor 16 to run in reverse so that the hemming head resets; 4. Controlling the pneumatic-hydraulic booster cylinder 17 to rise and return to the initial position; 5. Visually inspecting whether the hemming operation is qualified. If it is qualified, proceed to the next operation.

[0075] In one embodiment, such as Figure 4 As shown, the fourth driving component includes a workpiece translation cylinder 8 and a transfer slide rail 10 connected to the control device; two transfer guide columns are vertically arranged on the frame, and a transfer moving plate 12 is slidably sleeved on the two transfer guide columns. A transfer fixing plate is provided on the top of the two transfer guide columns. The fixed end of the workpiece translation cylinder 8 and the transfer slide rail 10 are both located on the transfer fixing plate. The moving end of the workpiece translation cylinder 8 is connected to the gripper mechanism 11. The transfer guide columns are provided with multiple fixing holes along the axial direction for fixing the position of the transfer moving plate 12.

[0076] It should be noted that the transfer fixing plate can be set on the welded base plate 39 of the frame. The gripper mechanism 11 is fixedly connected to the transfer moving plate 12, and the transfer moving plate 12 is detachably connected to the transfer guide column. All fixedly connected plates can be connected by positioning pins to ensure that the relative positions remain unchanged after long-term movement and to ensure repeatability accuracy. During use, the end of the drive shaft 42 can be placed on the transfer moving plate 12, and the other end of the drive shaft 42 with the AC joint 45 is fixed by the gripper of the gripper mechanism 11 to achieve fixed clamping of the drive shaft 42, which facilitates the switching operation of the drive shaft 42 between the press-fit position and the roll-edge position.

[0077] In one embodiment, the transfer fixing plate is provided with a first detector for detecting the presence of a drive shaft 42 at the pressing position, a second detector for detecting the presence of a drive shaft 42 at the rolling position, and a buffer mechanism 9. The buffer mechanism 9 is provided corresponding to the pressing position and the rolling position. Both the first and second detectors are connected to a control device. Therefore, when the first detector detects the drive shaft 42, it indicates that the drive shaft 42 is located at the pressing position, and the control device can control the pressing mechanism 1 or the transfer mechanism 3 to perform corresponding operations. When the second detector detects the drive shaft 42, it indicates that the drive shaft 42 is located at the rolling position, and the control device can control the rolling device 2 or the transfer mechanism 3 to perform corresponding operations. The buffer mechanism 9 can buffer and protect the moving drive shaft 42 and related components.

[0078] In one embodiment, such as Figures 9-11 As shown, the frame includes a bottom frame 6 and a top frame 7. The bottom frame 6 includes a welding base 37, feet 38 located at the bottom of the welding base 37, and a welding base plate 39 located at the top of the welding base 37. The top frame 7 includes a profile frame 40 located on the welding base plate 39 and a safety light curtain 41 located on the profile frame 40. The frame is used to integrate the various components, resulting in a tight fit between the devices, a compact device structure, and a relatively small footprint.

[0079] To further illustrate the usage of the cover riveting device for drive shaft end sections provided by this utility model, the following example will be given.

[0080] Step 1, Product loading and pressing of inner cover 43: The operator manually takes the preceding drive shaft 42, with the AC section 45 of the drive shaft 42 facing upwards and the shaft end of the drive shaft 42 facing downwards. Using the 6 holes of the AC section 45 for positioning, the operator manually takes the glued cover sleeve assembly and installs it on the front shaft tube. The operator manually removes the outer cover 44 and places it into the outer pressing head. At this time, the inner pressing head is in the pressing position. The first detector checks whether the drive shaft 42 is present. If it is, the press 21 is started, and then the inner pressing head is controlled to descend. The press 21 presses the inner cover 43 and AC section 45 into place. Then, the press 21 returns to its original position, and the next mechanism can be performed.

[0081] Step 2, Steel Ball Detection: First, control the detection translation cylinder 33 to extend horizontally. Then, control the detection lifting cylinder 32 to descend, causing the detection head 34 to move to the detection position. The detection head 34 contains spring probes of the same number as the steel balls, which are inserted into the corresponding steel ball positions. After the probe detects a steel ball, it retracts. The same number of proximity switches at the tail end of the probe detect whether the probe has retracted. The position corresponding to the retracted probe has a steel ball, and the position corresponding to the unretracted probe has no signal from the proximity switch, that is, there is no steel ball. If the number of steel balls is incorrect, it is unqualified and the unqualified products need to be removed manually. If it is qualified, after the steel ball detection operation is completed, it enters the next mechanism.

[0082] Step 3, Lubrication of AC Section 45 End Face: First, control the grease injection translation cylinder 28 to extend horizontally, then control the grease injection lifting cylinder 27 to descend, pressing the grease injection head 31 onto the AC section 45 end face. Subsequently, grease injection of AC section 45 end face is performed by relying on the pump station-pressure stabilizing valve-flow meter-switching valve-grease injection head 31. The pump station provides grease, the pressure stabilizing valve controls the pressure, the flow meter monitors the grease injection volume, the switching valve controls the grease injection speed and the on / off of the grease, and the grease injection head 31 injects the grease into the required position. After the grease injection is completed, control the grease injection lifting cylinder 27 to rise and control the grease injection translation cylinder 28 to retract horizontally, entering the next mechanism;

[0083] Step 4, Pressing the outer cover 44: Control the switching cylinder 22 to move the outer pressure head with the outer cover 44 to the pressing position of the pressing mechanism 1, so that the outer pressure head and AC section 45 are aligned and distributed. Control the press 21 to move downward, press the outer pressure head with the outer cover 44 onto the end face of AC section 45, drive the outer pressure head to perform the pressing operation on AC section 45. After the pressing operation of the outer cover 44 is completed, control the press 21 to reset upward to make room for the operation position.

[0084] Step 5, Switch to the hemming position: First, control the pneumatic-hydraulic booster cylinder 17 to press down, so that the three-jaw chuck 13 clamps the AC section 45; then, control the servo motor 16 to run, so that the hemming head of the three-jaw chuck 13 (the hemming head conforms to the hemming position) rotates to perform the hemming operation; then, control the servo motor 16 to run in reverse, so that the hemming head resets; subsequently, control the pneumatic-hydraulic booster cylinder 17 to rise, returning to the initial position; finally, visually inspect whether the hemming operation is qualified, if qualified, proceed to the next operation;

[0085] Step 7, manual unloading: After the rolling operation is completed, control the workpiece translation cylinder 8 to move in the opposite direction, so as to drive the gripper mechanism 11 and the transfer plate 12 to move synchronously, so that the transmission shaft 42 moves from the rolling position of the rolling device 2 back to the pressing position of the pressing mechanism 1. Then control the gripper mechanism 11 to release, so as to remove the transmission shaft 42 that has completed the processing operation.

[0086] If the equipment is not used for a long time, or needs to be restarted due to sudden power outages or gas outages, the equipment needs to be initialized. Confirm that all cylinders are in the initial feeding state and that there are no missing products in the equipment. Ensure the safety of the equipment before restarting it.

[0087] As described above, after the equipment is started, it can automatically complete the processes of pressing the 45-inch end cap of the AC section, steel ball detection, grease injection, and edge rolling. This integrates four processes into one machine, significantly saving labor and time costs. Furthermore, by controlling the movement sequence of the mechanism, products with missing steel balls can be detected and manually assembled in the middle of the process, greatly reducing the scrap rate. Compared to manual assembly with mechanical tooling, the fully automated equipment is faster, more consistent, and produces higher quality products. Defective parts can be removed, ensuring 100% product quality. Compared to manual screening, the mechanical success rate is higher, and the NG rate is also significantly reduced, thus greatly saving raw materials and costs.

[0088] Taking one person's annual output as an example: Traditional manual assembly requires four people, each taking 60 seconds per piece, working two shifts of 8 hours each, totaling 16 hours a day. Four people can assemble 365 x 16 x 60 x 60 / 60 = 350,400 pieces per year. Using this device, the cycle time for mechanical and manual assembly is 60 seconds per piece. Four machines and four people can assemble 4 x 365 x 16 x 60 x 60 / 60 = 1,401,600 pieces per year. Compared to manual assembly, mechanical assembly efficiency is increased by 4 times. Furthermore, the product qualification rate for manual assembly is typically 95%, while the product qualification rate for mechanical assembly is 99.7%. Therefore, using this device can effectively improve product quality and assembly efficiency.

[0089] It should be noted that the first driving component, the second driving component, the third driving component, the fourth driving component, the first support column 36 and the second support column 29, the first linear guide rail 35 and the second linear guide rail 30, the first detector and the second detector mentioned in this application are only distinguished by their different positions and do not have any order of precedence.
