Description

Technical Field

[0001] This utility model relates to an automatic removal device for process pins used in differential assembly, belonging to the field of differential assembly technology. Background Technology

[0002] During the assembly of the differential, elastic pins need to be installed in the pre-drilled holes in the differential housing to securely connect the upper and lower housings. Before installing the elastic pins, process pins need to be pre-installed in the pre-drilled holes in the differential housing to pre-fix the upper and lower housings. This prevents misalignment or displacement of the housings during the processes prior to elastic pin installation, which could affect the normal operation of the processes preceding elastic pin installation.

[0003] Because the differential housing has pre-fixed process pins in its reserved holes, when it is necessary to install the spring pin in the reserved holes of the differential housing, the process pins in the reserved holes must be removed first, and then the spring pin can be installed. However, the removal of process pins used in existing differential assembly is mostly done manually, which is costly, has low automation, and low work efficiency, and cannot meet the requirements of high-efficiency assembly lines for differential assembly.

[0026] like Figures 1 to 5 As shown, this utility model provides an automatic removal device for process pins used in differential assembly, including a frame 3, on which a conveyor frame 4 and a gripper mechanism 1 located above the conveyor frame 4 are mounted. A tray 5 for carrying a differential 6 is slidably connected to the conveyor frame 4. A lifting mechanism 2 is installed below the frame 3, located below the conveyor frame 4. The lifting mechanism 2 includes a lifting drive mechanism 21 for driving the tray 5 and the differential 6 on the tray 5 to move up and down. The gripper mechanism 1 is located above the lifting mechanism 2 and includes a movable gripper 17 for removing the process pin 7 from the reserved hole 61 of the differential 6.

[0027] In some embodiments, the gripper mechanism 1 further includes a column 18 fixedly mounted on the frame 3, a first mounting base 19 fixedly mounted on the column 18, a linear module 11 fixedly connected to the first mounting base 19, a first mounting plate 12 connected to the output end of the linear module 11, a first cylinder 13 fixedly mounted on the first mounting plate 12, a second mounting plate 14 connected to the output end of the first cylinder 13, a second cylinder 15 fixedly mounted on the second mounting plate 14, and a gripper cylinder 16 connected to the output end of the second cylinder 15. The output end of the gripper cylinder 16 is connected to the gripper 17; the linear module 11 is used to drive the first mounting plate 12, the first cylinder 13, the second mounting plate 14, the second cylinder 15, the gripper cylinder 16, and the gripper 17 to move laterally; the first cylinder 13 is used to drive the second mounting plate 14, the second cylinder 15, the gripper cylinder 16, and the gripper 17 to move longitudinally; the second cylinder 15 is used to drive the gripper cylinder 16 and the gripper 17 to move longitudinally; and the gripper cylinder 16 is used to drive the gripper 17 to open or close.

[0028] In this embodiment, the first mounting plate 12, the first cylinder 13, the second mounting plate 14, the second cylinder 15, the gripper cylinder 16, and the gripper 17 are driven by the linear module 11 to move laterally, thereby achieving the lateral movement of the gripper 17. The first cylinder 13 drives the second mounting plate 14, the second cylinder 15, the gripper cylinder 16, and the gripper 17 to move longitudinally, and the second cylinder 15 drives the gripper cylinder 16 and the gripper 17 to move longitudinally, thereby achieving the longitudinal movement of the gripper 17. The combined design of the first cylinder 13 and the second cylinder 15 increases the longitudinal displacement of the gripper 17, thus adapting to differentials 6 of different heights and specifications, and expanding the applicability of the device. The gripper cylinder 16 drives the gripper 17 to open or close, allowing the gripper 17 to remove the process pin 7 from the pre-drilled hole 61 in the differential 6.

[0029] In some embodiments, the lifting mechanism 2 further includes a second mounting base 22 fixedly installed in the frame 3, and the lifting drive mechanism 21 is fixedly installed below the second mounting base 22. The output end of the lifting drive mechanism 21 is connected to a lifting plate 23, which is located below the conveyor frame 4. The lifting drive mechanism 21 is used to drive the lifting plate 23 to perform lifting and lowering movements.

[0030] Optionally, the second mounting base 22 is fixedly mounted with a linear bearing 25, and the lifting plate 23 is fixedly mounted with a guide shaft 24, which is movably inserted into the linear bearing 25.

[0031] In this embodiment, when the pallet 5 moves directly above the lifting plate 23, the lifting drive mechanism 21 drives the lifting plate 23 to move up and down. The lifting plate 23 drives the pallet 5 and the differential 6 on the pallet 5 to move up and down, thereby lifting the differential 6 so that the gripper 17 of the gripper mechanism 1 can perform the process pin 7 removal operation on the lifted differential 6. The guide shaft 24 of the lifting plate 23 is movably inserted into the linear bearing 25 of the second mounting base 22, providing guidance for the lifting movement of the lifting plate 23, facilitating a smoother lifting movement and ensuring that the pallet 5 and the differential 6 on the pallet 5 remain level during the lifting process, thus facilitating the gripper 17 to remove the process pin 7.

[0032] Optionally, the lifting drive mechanism 21 is a cylinder.

[0033] In some embodiments, a first sensor 41 is fixedly installed on one side of the conveyor frame 4. The first sensor 41 is used to detect whether the differential 6 on the tray 5 is running under the gripper mechanism 1.

[0034] Optionally, the first sensor 41 is located below the gripper mechanism 1.

[0035] In this embodiment, when the first sensor 41 detects that the differential 6 on the tray 5 has moved below the gripper mechanism 1, the gripper mechanism 1 and the lifting mechanism 2 are activated to begin the process pin removal operation on the differential 6.

[0036] In some embodiments, a second sensor 42 is fixedly installed on one side of the conveyor frame 4. The second sensor 42 is used to detect whether there is a process pin 7 in the reserved hole 61 provided in the differential 6.

[0037] Optionally, the second sensor 42 is located below the gripper mechanism 1.

[0038] In this embodiment, after the automatic process pin removal device completes the process pin removal process, the second sensor 42 detects whether there is a process pin 7 in the reserved hole 61 set in the differential 6. This allows the device to detect whether it has successfully removed the process pin 7 from the differential 6 on the tray 5. An additional detection process after the process pin is removed is added to ensure the accuracy of the device operation.

[0039] In some embodiments, a process pin mounting seat 51 for storing process pins 7 is fixedly installed on the tray 5, and the process pin mounting seat 51 is located on one side of the differential 6.

[0040] In this embodiment, after the gripper 17 removes the process pin 7, it places the process pin 7 into the process pin mounting base 51.

[0041] The working process of the automatic removal device for process pins used in differential assembly provided by this utility model is as follows:

[0042] The conveyor frame 4 drives the pallet 5 and the differential 6 on the pallet 5 to move to the bottom of the gripper mechanism 1. The first sensor 41 detects whether the differential 6 is in position. After the differential 6 is in position, the gripper mechanism 1 and the lifting mechanism 2 are started.

[0043] The lifting mechanism 21 of the lifting mechanism 2 drives the lifting plate 23 to rise, and the lifting plate 23 drives the tray 5 and the differential 6 on the tray 5 to be lifted. The linear module 11 of the gripper mechanism 1 drives the first mounting plate 12, the first cylinder 13, the second mounting plate 14, the second cylinder 15, the gripper cylinder 16, and the gripper 17 to move laterally. The first cylinder 13 drives the second mounting plate 14, the second cylinder 15, the gripper cylinder 16, and the gripper 17 to move longitudinally. The second cylinder 15 drives the gripper cylinder 16 and the gripper 17 to move longitudinally, so that the gripper 17 moves to the process pin 7 in the reserved hole 61 of the differential 6.

[0044] The gripper cylinder 16 drives the gripper 17 to close, clamping and fixing the process pin 7. The first cylinder 13 and the second cylinder 15 drive the gripper 17 and the process pin 7 in the gripper 17 to rise, thereby removing the process pin 7 from the reserved hole 61 of the differential 6. The linear module 11, the first cylinder 13, and the second cylinder 15 drive the gripper 17 and the process pin 7 in the gripper 17 to move to the process pin mounting seat 51. The gripper cylinder 16 drives the gripper 17 to open, so as to put the process pin 7 into the process pin mounting seat 51.

[0045] When the gripper 17 removes the process pin 7 from the reserved hole 61 of the differential 6, the second sensor 42 detects whether the process pin 7 exists in the reserved hole 61 of the differential 6, thereby detecting whether the automatic process pin removal device has successfully removed the process pin 7 from the differential 6 on the tray 5.

[0046] In summary, the automatic process pin removal device for differential assembly provided by this utility model has a high degree of automation and high working efficiency, greatly saving labor costs and meeting the requirements of high-efficiency assembly in differential assembly production lines. Through the cooperation of the gripper mechanism 1, lifting mechanism 2, conveyor frame 4, and tray 5, the device can automatically remove the process pin 7 from the reserved hole 61 of the differential 6, thus facilitating the subsequent installation of the elastic pin. Furthermore, the device uses a first sensor 41 to detect whether the differential 6 on the tray 5 has moved below the gripper mechanism 1, and a second sensor 42 to detect whether the process pin 7 exists in the reserved hole 61 of the differential 6. This allows the device to detect whether the automatic process pin removal device has successfully removed the process pin 7 from the differential 6 on the tray 5, adding a post-process pin removal detection step to ensure the accuracy of the device's operation.
