Description

Technical Field

[0001] This utility model relates to a press-fit lifting device and a differential assembly equipment, belonging to the field of differential assembly technology. Background Technology

[0002] During differential assembly, spring pins need to be installed in pre-drilled holes in the differential housing to securely connect the upper and lower housings. Currently, most spring pin installation methods are manual, resulting in high labor costs, low automation, and low efficiency. Another method uses a press-fitting machine to press the spring pins into the pre-drilled holes in the differential housing. However, this requires a press-fitting lifting device. The lifting device, located below the differential, lifts it up, and then the press-fitting machine, positioned above the differential, presses the spring pins into the lifted differential housing.

[0003] However, most existing press-fitting lifting devices used with press-fitting machines employ a single lifting mechanism to lift the differential. This method results in the press-fitting force of the press-fitting machine and the weight of the differential acting directly on the lifting mechanism. Especially when assembling heavier differentials, the lifting mechanism bears even greater pressure, making it prone to damage and reducing the device's lifespan and reliability. Furthermore, existing single lifting mechanisms, when bearing the press-fitting force of the press-fitting machine and the weight of the differential, are prone to uneven distribution of the press-fitting force or the weight of the differential due to limited load-bearing capacity. This can affect the pressing quality of the elastic pin, thereby reducing the overall assembly quality of the differential.

[0004] Therefore, the existing pressing and lifting devices have limited load-bearing capacity and cannot be adapted to differentials of different weights, resulting in poor adaptability. Furthermore, the limited load-bearing capacity can easily lead to uneven pressing force of the pressing machine or uneven weight distribution of the differential, which in turn affects the pressing quality of the elastic pin and thus reduces the assembly quality of the differential. In addition, the single lifting mechanism is prone to damage, which greatly reduces the service life and reliability of the device, thereby affecting the assembly efficiency of the differential.

[0027] like Figures 1 to 5 As shown, this utility model provides a press-fit lifting device, including a first mounting plate 1, a lifting mechanism 3 mounted on the first mounting plate 1, and a support block 5; the first mounting plate 1 has a through hole 62, the output end of the lifting mechanism 3 passes through the through hole 62 and is fixedly connected to a first connector 33, the first connector 33 is connected to a connecting seat 32, the connecting seat 32 is fixedly connected to a lifting seat 31, the lifting seat 31 is fixedly connected to a lifting plate 2, a differential 22 is mounted on the lifting plate 2, and the lifting mechanism 3 is used to drive the lifting plate 2 and the differential 22 to perform lifting and lowering movements; the support block 5 is connected to a driving mechanism 4, and the driving mechanism 4 is used to drive the support block 5 to move; the support block 5 has an opening slot 51 on the side facing the first connector 33 for accommodating the first connector 33 and the connecting seat 32.

[0028] In some embodiments, a second mounting plate 6 is fixedly connected to the first mounting plate 1, the drive mechanism 4 is fixedly mounted on the second mounting plate 6 via a second mounting base 42, and the output end of the drive mechanism 4 is fixedly connected to the carrier block 5 via a second connector 41.

[0029] In this embodiment, the output end of the drive mechanism 4 drives the carrier block 5 to move through the second connector 41.

[0030] In some embodiments, guide rails 61 are fixedly installed on both sides above the second mounting plate 6, the bearing block 5 is slidably connected to the guide rails 61, and the driving mechanism 4 is used to drive the bearing block 5 to move along the guide rails 61.

[0031] In this embodiment, the guide rails 61 fixedly installed on both sides above the second mounting plate 6 provide guidance for the movement of the support block 5, so that the support block 5 can move accurately along the guide rails 61, thus ensuring the movement accuracy of the support block 5.

[0032] In some embodiments, the support block 5 is provided with a chamfer 52 on the side facing the first connector 33, which communicates with the opening slot 51.

[0033] In this embodiment, the chamfer 52 serves a certain guiding and avoidance function, enabling the carrier block 5 to smoothly avoid the first connector 33 and the connector 32 during movement.

[0034] In some embodiments, the connector 32 is provided with an embedding groove 321 on the side facing the first connector 33, and the first connector 33 is provided with a head protrusion 331 on the side facing the connector 32, and the head protrusion 331 is embedded in the embedding groove 321.

[0035] In this embodiment, the head protrusion 331 is embedded in the embedding groove 321, so that the head protrusion 331 and the embedding groove 321 cooperate with each other to realize the connection between the connecting seat 32 and the first connecting head 33, thereby ensuring that the lifting mechanism 3 smoothly drives the lifting seat 31, the lifting plate 2 and the differential 22 to perform lifting and lowering movements through the first connecting head 33 and the connecting seat 32.

[0036] In some embodiments, the lifting plate 2 is fixedly connected to a plurality of optical axes 5, the first mounting plate 1 is fixedly connected to a plurality of linear bearings 7, and the plurality of optical axes 5 are slidably connected to the plurality of linear bearings 7 respectively; a connecting plate 9 is fixedly connected below the optical axis 8, and two adjacent optical axes 8 are connected by the connecting plate 9.

[0037] In this embodiment, the optical axis 5 of the lifting plate 2 cooperates with the linear bearing 7 of the first mounting plate 1 to guide the lifting movement of the lifting plate 2, ensuring that the lifting plate 2 moves vertically and thus ensuring the pressing accuracy of the press-fitting machine. Simultaneously, it keeps the first mounting plate 1 horizontal, ensuring a uniform distribution of the pressing force of the press-fitting machine or the gravity of the differential 22, avoiding affecting the pressing quality of the elastic pin, thereby improving the assembly quality of the differential 22.

[0038] In some embodiments, a first mounting base 21 is fixedly connected to the lifting plate 2, and a differential 22 is mounted on the first mounting base 21. The differential 22 is fixedly mounted via the first mounting base 21.

[0039] In some embodiments, a positioning pin 23 is provided on the edge of the upper surface of the lifting plate 2.

[0040] In this embodiment, the positioning pin 23 is used to cooperate with the pressing machine above the lifting plate 2 during the lifting process, and plays a positioning role. It can ensure that the pressing machine is aligned with the reserved hole in the differential housing, thereby ensuring that the elastic pin is accurately pressed into the reserved hole in the differential housing.

[0041] Optionally, both the lifting mechanism 3 and the driving mechanism 4 are cylinders.

[0042] The working principle of the press-fit lifting device provided by this utility model is as follows: When the assembly of the differential 22 reaches the elastic pin press-fitting process, the output end of the lifting mechanism 3 drives the first connector 33 to lift through the through hole 62. The first connector 33 drives the lifting seat 31 to lift through the connecting seat 32. The lifting seat 31 drives the lifting plate 2 to lift, thereby completing the lifting of the differential 22 on the lifting plate 2. After the differential 22 is lifted, the drive mechanism 4 drives the bearing block 5 to move along the guide rail 61 through the second connector 41, so that the bearing block 5 moves to below the lifting seat 31. At this time, the first connector 33 and the connecting seat 32 are located in the opening groove 51. The chamfer 52 on the side of the bearing block 5 facing the first connector 33 communicates with the opening groove 51, so that the bearing block 5 can smoothly avoid the first connector 33 and the connecting seat 32 during the movement. After the support block 5 moves below the lifting seat 31, the lifting mechanism 3 retracts, and the lifting seat 31 descends until it abuts against the support block 5. At this time, the support block 5 bears the weight of the entire lifting seat 31, the lifting plate 2, and the differential 22. The press-fitting machine directly above the reserved hole in the differential housing begins the press-fitting operation, pressing the elastic pin into the reserved hole in the differential housing. After the elastic pin is pressed in, the press-fitting machine returns to its original position, the lifting mechanism 3 drives the differential 22 to rise, the drive mechanism 4 retracts, and after the support block 5 returns to its initial position, the lifting mechanism 3 drives the differential 22 to descend, so that the differential 22, after the elastic pin press-fitting operation is completed, returns to its initial position, thus completing the elastic pin press-fitting process during differential assembly.

[0043] In summary, the pressing and lifting device provided by this utility model, through the cooperation of the lifting mechanism 3 and the drive mechanism 4, allows the lifting mechanism 3 to lift the differential 22. After the lifting mechanism 3 completes the lifting of the differential 22, the drive mechanism 4 drives the bearing block 5 to move below the lifting seat 31, and then the lifting mechanism 3 retracts. Thus, the bearing block 5 bears the pressing force of the pressing machine and the weight of the differential, preventing the lifting mechanism 3 from directly bearing the pressing force of the pressing machine or the weight of the differential, thereby protecting the lifting mechanism 3 and effectively preventing damage to it. This significantly improves the service life and reliability of the device, thereby increasing the assembly efficiency of the differential. Furthermore, the bearing block 5 has a strong force-bearing capacity, can adapt to differentials 22 of different weights, has high adaptability, and can also ensure a uniform distribution of the pressing force of the pressing machine or the weight of the differential 22, avoiding affecting the pressing quality of the elastic pin, thereby improving the assembly quality of the differential 22.

[0044] Furthermore, this utility model also provides a differential assembly device, which includes the press-fit lifting device described in any of the above-mentioned embodiments. Because the differential assembly device includes the press-fit lifting device described in any of the above-mentioned embodiments, it possesses all the advantages mentioned above.
