[0026] 2. The sleeve riveting assembly equipment of the present invention facilitates the repair of deformed sleeve shapes through the installation of clamping blocks and a second electric push rod. When it is necessary to reset the slightly deformed sleeve surface, the second electromagnet is controlled to generate a strong magnet, which in turn positions the transmission block. The transmission block positions the detection block, and the second electric push rod is controlled to move the receiving groove. When the receiving groove moves, the position of the detection block is adjusted, so that the detection block moves to one side of the sleeve, thereby causing the sleeve to rotate. When the deformed sleeve is in contact with the surface of the detection block, the fixed position of the detection block applies pressure to the sleeve surface, restoring the sleeve shape. This achieves the purpose of simple sleeve shape repair, effectively avoiding material waste, reducing the replacement loss of defective sleeves, indirectly compressing production costs, and avoiding quality problems such as riveting misalignment and poor workpiece fit caused by sleeve deformation.

After the sleeve moves into the rotating ring, the driving motor No. 3 drives the No. 1 reducer to move. The movement of the No. 1 reducer drives the adjusting screw to move. When the adjusting screw moves, it adjusts the position of the clamping block. After the clamping block moves and contacts the sleeve surface, it limits and fixes the position of the sleeve. Then, when the worm gear moves, it causes the rotating ring to move through the worm wheel. The movement of the rotating ring causes the sleeve to be assembled to rotate, which facilitates the full observation and inspection of the sleeve surface. When the sleeve rotates 360 degrees, the inspection camera can collect real-time images of the assembly point between the sleeve and the workpiece. The collected images are displayed by the inspection camera, which facilitates the inspection of the sleeve surface and avoids the waste of finished products due to the failure to detect defects on the sleeve surface in time.

[0043] A supporting block 34 is fixedly arranged on the workbench 1, a cylinder 35 is fixedly arranged in the supporting block 34, an annular groove 36 is arranged on the cylinder 35, a rotating ring 37 is rotatably arranged in the annular groove 36, a clamping assembly is fixedly connected to the inner circle of the rotating ring 37, a frame 47 is arranged in the supporting block 34, a power mechanism for driving the rotating ring 37 to move is arranged in the frame 47, and a strip-shaped frame 62 is fixedly arranged on the side surface of the supporting block 34;

[0044] A through groove 61 is arranged in the cylinder 35, a receiving groove 64 corresponding to the through groove 61 is arranged in the strip-shaped frame 62, one end of the receiving groove 64 extends into the through groove 61, a detection block 65 is arranged in the receiving groove 64, one end of the detection block 65 extends into the through groove 61, a detection assembly is arranged in the receiving groove 64, and a warning lamp 63 is fixedly arranged on the strip-shaped frame 62;

[0045] A second electric push rod 76 is fixedly arranged in the strip-shaped frame 62, and the telescopic end of the second electric push rod 76 is fixedly connected to one side of the receiving groove 64;

[0046] The electronic device on the sleeve riveting assembly equipment without a special power supply is externally connected to a power supply, and the controller 2 is electrically connected to the electronic device, so as to control the electronic device on the sleeve riveting assembly equipment to work;

[0047] When the sleeve riveting assembly equipment is used to assemble and process the sleeve workpiece, the sleeve to be assembled is fed by the feeding mechanism, and the sleeve is clamped and limited by the clamping assembly after the sleeve moves into the limiting frame 11. The power mechanism is controlled to move, so as to drive the rotating ring 37 to rotate in the annular groove 36, and then drive the sleeve to rotate. When the sleeve rotates by 360 degrees, the surface of the sleeve is detected, so as to avoid the waste caused by the fact that the defects on the surface of the sleeve are not found in time and the assembly is not carried out in time;

[0048] The detection block 65 is moved to one side of the sleeve to be detected through the through groove 61, and then the sleeve is driven to perform circumferential motion. When the surface deformation of the sleeve is serious, the detection block 65 will be moved, and the movement of the detection block 65 will make the detection assembly move. Through the cooperation of the detection assembly, the warning light 63 will work to emit light, thereby facilitating personnel to timely find out whether the sleeve meets the assembly standard, reducing the scrap of the assembled materials and supporting materials, reducing the direct material cost. Compared with the problem found after assembly and then disassembled, repaired and maintained, the time and cost input of the early investigation is extremely low, but it can avoid the chain loss of multiple links, and is suitable for batch assembly production scene. After detecting that the sleeve has no problem, the sleeve is moved to the predetermined position, and the sleeve position is positioned and clamped. The workpiece riveted with the sleeve is fixed on the feeding mechanism, so that the workpiece and the sleeve are concentrically arranged. Through the movement of the feeding mechanism, the workpiece and the sleeve assembly are connected, the pre-set hole of the workpiece and the sleeve is aligned, the worker takes the pre-made rivet, and after the rivet passes through the sleeve and the pre-set hole inside the workpiece, the first electric push rod 27 is controlled to move, which pushes the riveting head 28 to move. The riveting head 28 moves to press the rivet, so that the rivet is deformed, and then the sleeve and the workpiece are fixedly connected, so as to achieve the purpose of riveting assembly.

[0049] Further, the workbench 1 is fixedly provided with a controller 2 on the side. The feeding mechanism comprises a storage tank 3, a rotating shaft 4, a groove 5 and a power motor 6. The storage tank 3 is fixedly arranged on the workbench 1. The rotating shaft 4 is rotatably arranged in the storage tank 3. The groove 5 is arranged on the rotating shaft 4. The power motor 6 is fixedly arranged on the side of the storage tank 3, and the output end of the power motor 6 is fixedly connected with the end of the rotating shaft 4.

[0050] The feeding mechanism further comprises a mounting frame 7, a first conveying belt 8, a first motor 9 and a conical groove 10. The mounting frame 7 is fixedly arranged on the top of the workbench 1, and the mounting frame 7 is located directly below the storage tank 3. The first conveying belt 8 is arranged in the mounting frame 7. The first motor 9 is fixedly arranged on the side of the mounting frame 7, and the output end of the first motor 9 is drivingly connected with the first conveying belt 8. The conical groove 10 is fixedly arranged at one end of the mounting frame 7.

[0051] The sleeve riveting assembly device can be controlled to work through the controller 2. The sleeves to be assembled can be neatly placed in the storage groove 3 for storage. When the sleeves need to be assembled, the power motor 6 is controlled to work to drive the rotating shaft 4 to move. When the rotating shaft 4 moves, the groove 5 moves, so that the sleeves stored in the storage groove 3 enter the groove 5. The rotating shaft 4 continues to move, and the sleeves move in the groove 5, so that the sleeves move to the mounting frame 7. The sleeves are supported by the first conveyor belt 8. The first motor 9 is controlled to work to drive the first conveyor belt 8 to move, so that the sleeves can be conveyed. The sleeves are calibrated by the conical groove 10, and then enter the limiting frame 11 for conveying.

[0052] Further, the limiting frame 11 is fixedly arranged on the workbench 1 and communicates with one end of the conical groove 10. The limiting frame 11 is internally provided with the second conveyor belt 12.

[0053] The support 26 is fixedly provided with the detection camera 29 at the bottom, and the display screen 30 is fixedly arranged on the support 26, and the detection camera 29 is in electrical connection with the display screen 30.

[0054] The workbench 1 is internally provided with the square groove 31. The square groove 31 is internally provided with the bearing block 33. The square groove 31 is fixedly provided with the sixth electric push rod 32, and the extension end of the sixth electric push rod 32 is fixedly connected with the bottom of the bearing block 33. The bearing block 33 is located directly below the riveting head 28.

[0055] After the sleeve enters the limiting frame 11, the second motor 13 is controlled to work to drive the second conveyor belt 12 to move. The second conveyor belt 12 moves to push the sleeve to move, so as to adjust the position of the sleeve. When the position of the sleeve needs to be positioned, the third electric push rod 14 is controlled to work to drive the clamping block 15 to move. After the clamping block 15 moves to one side of the sleeve, the position of the sleeve is positioned, so as to position the position of the sleeve.

[0056] The detection camera 29 can collect real-time images of the sleeve and the workpiece assembly (prior art). The collected images are displayed by the detection camera 29, so that the operator can observe the riveting assembly status of the workpiece in real time.

[0057] After the sleeve is connected to the workpiece and before riveting, the movement of the No. 6 electric push rod 32 can be controlled according to the different sleeve volumes. This will push the load-bearing block 33 to move to the bottom of the sleeve, thereby supporting the connection. During the riveting process, this can prevent deformation of the assembly due to the lack of support at the bottom.

[0058] Furthermore, the feeding mechanism includes a concave frame 17, a trough 18, a plate 19, a fourth electric push rod 20, a guide shaft 21, and a guide cylinder 22.

The worktable 1 is provided with a slide groove 16, and a T-shaped block 23 is provided inside the slide groove 16. The top of the T-shaped block 23 is fixedly connected to the concave frame 17. The worktable 1 is fixedly provided with a shaft 24, and the shaft 24 passes through the T-shaped block 23. The worktable 1 is fixedly provided with a No. 5 electric push rod 25, and the telescopic end of the No. 5 electric push rod 25 is fixedly connected to the T-shaped block 23.

[0059] When the workpiece for sleeve assembly is fed by the feeding mechanism, after the workpiece is placed inside the concave frame 17, the operation of the fourth electric push rod 20 will push the plate 19 to move. When the plate 19 moves, it will drive the guide shaft 21 to move. With the cooperation of the guide cylinder 22, the plate 19 will be guided, so that the plate 19 moves smoothly. When the opposing plate 19 moves and comes into contact with the surface of the workpiece, it will limit and clamp the workpiece. After the position of the workpiece is fixed, when feeding the workpiece and assembling the sleeve, the operation of the fifth electric push rod 25 will push the T-block 23 to move. The movement of the T-block 23 will be guided by the shaft 24, so that the T-block 23 moves smoothly. The movement of the T-block 23 will drive the concave frame 17 to move. The concave frame 17 can drive the workpiece to move, so that the workpiece can be fed and the sleeve can be assembled.

[0060] Furthermore, a worm gear 38 is fixedly connected to the outer ring of the rotating ring 37. The clamping assembly includes a sliding groove 39, a power supply module 40, a third motor 41, and a first reducer 42. The sliding grooves 39 are arranged in a circular array inside the rotating ring 37. The power supply module 40, corresponding to the sliding grooves 39, is embedded inside the rotating ring 37. The third motor 41 is fixedly installed inside the sliding groove 39, and the first reducer 42 is fixedly installed inside the sliding groove 39. The output end of the third motor 41 is fixedly connected to the input end of the first reducer 42. Next, the clamping assembly also includes an adjusting screw 43, a clamping block 44, and a limiting shaft 45. The adjusting screw 43 is disposed inside the sliding groove 39, and one end of the adjusting screw 43 is fixedly connected to the output end of the first reducer 42. The clamping block 44 passes through the sliding groove 39, and the outer surface of the adjusting screw 43 is threadedly connected to the inside of the clamping block 44. The limiting shaft 45 passes through the clamping block 44, and the other end of the limiting shaft 45 is fixedly connected to the inner wall of the sliding groove 39. The rotating ring 37 is provided with a ring array of linkage shafts 46.

[0061] The power supply module 40 is electrically connected to the No. 3 motor 41 to provide power to the No. 3 motor 41. The No. 3 motor 41 is a remote control motor (existing technology) and can be remotely controlled to operate the No. 3 motor 41.

[0062] When the rotating ring 37 clamps the sleeve using the clamping assembly, the sleeve moves into the rotating ring 37. This causes the third motor 41 to work, which in turn drives the first reducer 42. The movement of the first reducer 42, in turn, drives the adjusting screw 43. The adjustment screw 43 adjusts the position of the clamping block 44. After the clamping block 44 moves and contacts the sleeve surface, it limits and fixes the position of the sleeve. Then, when the worm gear 50 moves, it works with the worm wheel 38 to make the rotating ring 37 move. The movement of the rotating ring 37 causes the assembled sleeve to rotate, facilitating thorough observation and inspection of the sleeve surface. The rotation of the rotating ring 37 drives the linkage shaft 46 to move, which in turn drives the support ring 55 to move.

[0063] Furthermore, a filter screen 48 is fixedly installed inside the frame 47. The power mechanism includes a load-bearing ring 49, a worm gear 50, a second reducer 51, and a fourth motor 52. The load-bearing ring 49 is fixedly installed inside the frame 47. The worm gear 50 is rotatably installed inside the load-bearing ring 49 and meshes with the worm wheel 38. The second reducer 51 is fixedly installed inside the frame 47, and the output end of the second reducer 51 is fixedly connected to the end of the worm gear 50. The fourth motor 52 is fixedly installed inside the frame 47, and the output end of the fourth motor 52 is fixedly connected to the input end of the second reducer 51.

[0064] When outside air flows into the frame 47, it is filtered and purified by the filter screen 48. The load-bearing ring 49 supports the worm gear 50. The operation of the fourth motor 52 drives the second reducer 51 to move. When the second reducer 51 moves, it drives the worm gear 50 to rotate. Through the cooperation of the worm gear 50 and the worm wheel 38, the rotating ring 37 is driven to rotate.

[0065] Furthermore, an exhaust fan 53 is fixedly installed inside the frame 47, and the impeller inside the exhaust fan 53 is fixedly connected to one end of the worm gear 50 via a shaft. A nozzle 77 is installed at one end of the limit frame 11, and the output end of the exhaust fan 53 is connected to the nozzle 77 via a pipe. The nozzle 77 is located on one side of the cylinder 35.

[0066] When the worm gear 50 moves, it drives the exhaust fan 53 to move, which in turn generates airflow. The airflow enters the nozzle 77 through the pipe. The nozzle 77 allows the airflow to flow into the interior of the cylinder 35 on one side, cleaning the interior of the cylinder 35 and avoiding any impact on the surface quality of the sleeve.

[0067] Furthermore, the cylinder 35 has an annular groove 54 inside, and the side of the annular groove 54 is connected to the annular groove 36. A support ring 55 is rotatably arranged inside the annular groove 54, and the side of the support ring 55 is fixedly connected to the other end of the linkage shaft 46. An installation groove 56 is arranged in an annular array inside the support ring 55. A seventh electric push rod 57 is fixedly arranged inside the installation groove 56. A first electromagnet 58 is fixedly connected to the telescopic end of the seventh electric push rod 57. A connecting block 59 is arranged inside the installation groove 56, and the first electromagnet 58 is located inside the connecting block 59. The connecting block 59 is made of magnetic material, and a cleaning block 60 is fixedly arranged on the connecting block 59.

[0068] The cylinder 35 provides installation space for the support ring 55 through the annular groove 54. Inside the support ring 55, there is a battery corresponding to the No. 7 electric push rod 57. The battery provides power to the No. 7 electric push rod 57 and the No. 1 electromagnet 58. Both the electromagnet and the electric push rod can be remotely controlled (existing technology). Controlling the movement of the No. 7 electric push rod 57, the No. 1 electromagnet 58 and the connecting block 59 cooperate to push the cleaning block 60 to move. The cleaning block 60 can deform. When the cleaning block 60 contacts the surface of the sleeve, the sleeve connection can be cleaned when the sleeve rotates. When the rotating ring 37 rotates, it will drive the linkage shaft 46 to move. The linkage shaft 46 will drive the support ring 55 to move, control the No. 1 electromagnet 58 to stop working and no longer generate magnetic force, so that the No. 1 electromagnet 58 and the connecting block 59 can be separated. Then the connecting block 59 and the corresponding cleaning block 60 can be disassembled and replaced. Regular replacement can be performed to avoid excessive adsorption of impurities on the cleaning block 60, which will affect the cleaning effect.

[0069] Furthermore, a transmission block 71 is fixed to the side of the detection block 65, a guide frame 69 is fixedly installed inside the storage groove 64, and the transmission block 71 passes through the guide frame 69. A second electromagnet 70 is fixedly installed inside the guide frame 69, and the second electromagnet 70 is located on one side of the transmission block 71. The transmission block 71 is made of magnetic material. A guide groove 66 is provided inside the detection block 65, and a guide rod 67 passes through the guide groove 66. The other end of the guide rod 67 is fixedly connected to the guide frame 69. A reset spring 68 is arranged around the guide rod 67, and one end of the reset spring 68 is fixedly connected to the detection block 65, and the other end of the reset spring 68 is fixedly connected to the guide rod 67.

[0070] When the sleeve rotates, if the sleeve deforms excessively, it will push the detection block 65 to move. When the detection block 65 moves, it will drive the detection component to move through the transmission block 71, and at the same time, it will compress the reset spring 68. The guide groove 66 and the guide rod 67 cooperate to guide the detection block 65, so that the detection block 65 moves smoothly. The movement of the detection component will make the warning light 63 work, which can promptly remind the operator to find the sleeve abnormality, effectively avoiding the phenomenon of material waste caused by discovering defective products after assembly. When the sleeve is not in contact with the side of the detection block 65, the reset spring 68 resets, which will push the detection block 65 to move and reset. When the transmission block 71 moves, it will be guided by the guide frame 69, so that the transmission block 71 moves smoothly.

[0071] When it is necessary to reset the slightly deformed sleeve surface, the second electromagnet 70 is controlled to generate a strong magnet, which in turn positions the transmission block 71. The transmission block 71 then positions the detection block 65. The second electric push rod 76 is then controlled to move the receiving groove 64. As the receiving groove 64 moves, it adjusts the position of the detection block 65, moving it to one side of the sleeve. This causes the sleeve to rotate. When the deformed sleeve comes into contact with the surface of the detection block 65, the fixed position of the detection block 65 applies pressure to the sleeve surface, restoring the sleeve's shape. This achieves the purpose of simply repairing the sleeve's shape, effectively avoiding material waste. This method is used for slightly deformed and repairable sleeves. Severely deformed sleeves are processed separately using equipment and judged manually.

[0072] Furthermore, the detection component includes a first conductive sheet 72, a second conductive sheet 73, a limiting block 74, and a battery 75. The first conductive sheet 72 is fixedly mounted on the transmission block 71, and the second conductive sheet 73, corresponding to the first conductive sheet 72, is fixedly mounted inside the storage slot 64. The second conductive sheet 73 is electrically connected to the battery 75, the first conductive sheet 72 is electrically connected to the warning light 63, the battery 75 is fixedly mounted inside the storage slot 64, and the limiting block 74 is fixedly mounted on the transmission block 71.

[0073] When the sleeve deformation drive detection block 65 moves, the detection block 65 will drive the first conductive piece 72 to move through the transmission block 71. After the first conductive piece 72 moves and comes into contact with the second conductive piece 73, the current inside the battery 75 will enter the warning light 63, causing the warning light 63 to work and remind the staff.

[0074] Working Principle: First, when using the sleeve riveting assembly equipment to assemble sleeve workpieces, the sleeves to be assembled can be neatly placed inside the storage tank 3 for storage. When the sleeves need to be assembled, the control motor 6 drives the rotating shaft 4 to move. The movement of the rotating shaft 4 drives the groove 5 to move. After the groove 5 moves to the top, the sleeves stored in the storage tank 3 will enter the groove 5. The rotating shaft 4 continues to move, and through the movement of the groove 5, the sleeves will move into the mounting bracket 7. The sleeves are supported by the first conveyor belt 8. The control motor 9 drives the first conveyor belt 8 to move, thus conveying the sleeves. The conical groove 10 calibrates the position of the sleeves. After calibration, the sleeves will enter the limit... Inside the positioning frame 11 for conveying, after the sleeve enters the positioning frame 11, the second motor 13 is activated, driving the second conveyor belt 12. The movement of the second conveyor belt 12 pushes the sleeve to move, achieving the purpose of adjusting the sleeve's position. When the sleeve's position needs to be positioned, the third electric push rod 14 is activated, pushing the locking block 15 to move. After the locking block 15 moves to one side of the sleeve, it positions the sleeve. When the rotating ring 37 clamps the sleeve through the clamping assembly, after the sleeve moves into the rotating ring 37, the third motor 41 is activated, driving the first reducer 42 to move. The movement of the first reducer 42 drives the adjusting screw 43 to move. The movement of the adjusting screw 43 will adjust the position of the sleeve. The position of the clamping block 44 is adjusted. After the clamping block 44 moves and contacts the sleeve surface, it limits and fixes the position of the sleeve. Then, when the worm gear 50 moves, it will cause the rotating ring 37 to move through the worm wheel 38. The movement of the rotating ring 37 will drive the sleeve with assembly to rotate, which facilitates a thorough observation and inspection of the sleeve surface. When the sleeve rotates 360 degrees, the inspection camera 29 can acquire real-time images of the assembly point between the sleeve and the workpiece. The acquired images are displayed by the inspection camera 29, which facilitates the inspection of the sleeve surface and avoids the waste of finished products due to the failure to detect defects on the sleeve surface in time. When the sleeve rotates, if the sleeve deforms abnormally too much, it will push the inspection block 65 to move. When the inspection block 65 moves, it will transmit through the transmission The moving block 71 drives the detection component to move and compresses the reset spring 68. The guide groove 66 and guide rod 67 cooperate to guide the detection block 65, allowing it to move smoothly. The detection block 65, through the transmission block 71, drives the first conductive piece 72 to move. After the first conductive piece 72 contacts the second conductive piece 73, the current inside the battery 75 enters the warning light 63, activating the warning light to alert the staff. This facilitates timely detection of whether the sleeve meets the assembly standards, reducing the scrap of assembled materials and accessories, and lowering direct material costs. Compared to disassembly and repair after problems are discovered during assembly, the time and cost of initial troubleshooting are extremely low, while avoiding cascading losses from multiple stages. This is suitable for mass assembly production scenarios.When it is necessary to reset the slightly deformed sleeve surface, the second electromagnet 70 is activated to generate a strong magnet, which in turn positions the transmission block 71. The transmission block 71 then positions the detection block 65. The second electric push rod 76 is activated to move the receiving groove 64. As the receiving groove 64 moves, it adjusts the position of the detection block 65, moving it to one side of the sleeve. This causes the sleeve to rotate. When the deformed sleeve comes into contact with the surface of the detection block 65, the fixed position of the detection block 65 applies pressure to the sleeve surface, causing the sleeve to rotate. The sleeve is reshaped and thus easily repaired, effectively avoiding material waste. After the sleeve is inspected and found to be without problems, it is moved to a predetermined position and clamped. The workpiece riveted to the sleeve is then fixed on the feeding mechanism. After the workpiece is placed inside the concave frame 17, the operation of the fourth electric push rod 20 is controlled to push the plate 19 to move. When the plate 19 moves, it drives the guide shaft 21 to move. Through the cooperation of the guide cylinder 22, the plate 19 is guided, allowing it to move smoothly. The opposing plates 19... After contacting the workpiece surface during movement, the workpiece is clamped and limited. Once the workpiece position is fixed, during workpiece loading and sleeve assembly, the control of the No. 5 electric push rod 25 pushes the T-block 23 to move. The T-block 23 is guided by the shaft 24, ensuring smooth movement. The movement of the T-block 23 drives the concave frame 17 to move, which in turn moves the workpiece, allowing for workpiece loading and sleeve assembly. This aligns the workpiece with the pre-set holes on the sleeve, and the worker then retrieves the pre-made rivets. After the rivet passes through the pre-set holes inside the sleeve and workpiece, the movement of the sixth electric push rod 32, depending on the sleeve volume, will push the load-bearing block 33 to move below the sleeve, thus supporting the connection. This prevents deformation of the assembly due to lack of bottom support during riveting. Controlling the movement of the first electric push rod 27 will push the rivet head 28 to move, applying pressure to the rivet and causing it to deform, thereby fixing the sleeve and workpiece together and achieving the purpose of riveting assembly.
