Technical Field

[0001] This application relates to the field of differential assembly technology, and in particular to a workbench for differential assembly. Background Technology

[0002] As a key component of a car's transmission system, the differential's main function is to precisely adjust the speed difference between the left and right wheels when the car is turning. This function is of great significance for significantly improving the car's cornering performance and stability during driving.

[0003] The core structure of a differential includes important components such as the differential housing, planetary gears, and planetary gear shafts. The planetary gears are located inside the differential housing, while the planetary gear shafts are mounted on the differential housing, with the planetary gears nested on the shafts. The planetary gear shafts provide support and guidance for the planetary gears, ensuring that they operate stably according to predetermined motion paths and requirements.

[0004] Currently, during differential assembly, the differential housing is typically transported to the operator's vicinity via a conveyor line. The operator picks up the differential housing and then installs the planetary gears and planetary gear shafts onto it. To facilitate the installation of the planetary gears and planetary gear shafts, the differential housing needs to be rotated multiple times during assembly. After the differential assembly is complete, the operator must place the assembled differential back onto the conveyor line for the next installation step.

[0005] However, when assembling large quantities of differentials, workers need to pick up and rotate the differential housing multiple times, which results in a heavy workload and can easily lead to fatigue. Utility Model Content

[0054] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0055] This application discloses a workbench for assembling a differential.

[0056] A differential assembly workbench is provided, located at a specific position on a frame 1. The workbench includes a first platform 2 and a second platform 3, and a conveyor line 11 is provided on the frame 1. The first platform 2 is fixedly located below the conveyor line 11. The second platform 3 is located on the conveyor line 11. A lifting assembly 5 is provided on the first platform 2. The lifting assembly 5 is used to lift the second platform 3 away from the conveyor line 11. When the lifting assembly 5 and the second platform 3 come into contact, the lifting assembly 5 and the second platform 3 rotate in cooperation. The second platform 3 has a placement area for the differential housing 4.

[0057] In this embodiment, the conveyor line 11 is a roller conveyor line 11, and two roller conveyor lines 11 are provided. The second platform 3 is placed on the two roller conveyor lines 11. The differential housing 4 is pre-placed on the differential housing 4 placement area on the second platform 3. The second platform 3 conveys the differential housing 4 to directly above the first platform 2 via the roller conveyor lines 11.

[0058] The first platform 2 is fixed on the frame 1 and is located in the middle of the two roller conveyor lines 11. When the second platform 3 is conveyed to the top of the first platform 2, the lifting component 5 on the first platform 2 lifts the second platform 3 upward, so that the second platform 3 is removed from the roller conveyor line 11, thereby reducing the impact of roller vibration on the assembly of the differential.

[0059] When it is necessary to rotate the differential housing 4, the operator can directly rotate the second platform 3, which will drive the differential housing 4 to rotate.

[0060] After the differential is assembled, the second platform 3 is placed on the roller conveyor line 11 again by the lifting component 5, and then transported to the next process by the roller conveyor line 11.

[0061] The lifting assembly 5 is equipped with multiple positioning posts 6. The second platform 3 is equipped with multiple positioning holes 31. The positioning posts 6 are inserted into the positioning holes 31.

[0062] During the process of lifting the second platform 3 away from the roller conveyor line 11, the positioning pin 6 on the lifting assembly 5 is gradually inserted into the positioning hole 31 in the second platform 3, and the second platform 3 is positioned by the positioning pin 6. This improves the positional stability of the second platform 3 during its vertical movement.

[0063] When it is necessary to place the second platform 3 on the roller conveyor line 11, the positioning post 6 can be moved downward to disengage from the positioning hole 31, thereby releasing the restriction of the positioning post 6 on the second platform 3 and allowing the second platform 3 to move again on the roller conveyor line 11.

[0064] The second lifting platform 52 is provided with an annular limiting boss. The bottom of the second platform 3 is provided with a limiting groove. The limiting boss and the limiting groove are inserted into each other.

[0065] When the second platform 3 is lifted, the limiting boss is placed inside the limiting groove, and the limiting boss and the inside of the limiting groove further cooperate to improve the stability of supporting the second platform 3.

[0066] The lifting assembly 5 includes a first lifting platform 51 and a second lifting platform 52. The first lifting platform 51 is positioned above the first platform 2 via a first lifting drive unit. The second lifting platform 52 is positioned above the first lifting platform 51 via a second lifting drive unit. The second lifting platform 52 is rotatably engaged with the first lifting platform 51. A positioning post 6 is positioned on the second lifting platform 52.

[0067] The first lifting platform 51 and the second lifting platform 52 work together to move the second platform 3 vertically. The first lifting platform 51 moves the second platform 3 upward to detach it from the roller conveyor line 11 or moves the second platform 3 downward to place it on the roller conveyor line 11.

[0068] In the embodiments of this application, both the first lifting drive unit and the second lifting drive unit are cylinders.

[0069] In its initial state, the bottom of the second lifting platform 52 is in contact with the top of the first lifting platform 51 to enhance the overall structural strength of the lifting assembly 5. When it is necessary to rotate the second platform 3, the second lifting platform 52 is raised slightly away from the first lifting platform 51. Then, the operator rotates the second platform 3, which drives the second lifting platform 52 to rotate via the positioning column 6, thereby reducing the rotational friction between the second lifting platform 52 and the first lifting platform 51.

[0070] A positioning component 7 is provided between the first lifting platform 51 and the second lifting platform 52. The positioning component 7 includes a first stop 71 and a second stop 72. The first stop 71 is provided on the first lifting platform 51. There are multiple first stop blocks 71. The second stop 72 is provided on the second lifting platform 52. The second stop 72 is located between two adjacent first stop blocks 71.

[0071] When the second lifting platform 52 rotates, it drives the second stop block 72 to move between two adjacent first stop blocks 71, thereby limiting the rotation angle of the second lifting platform 52. In this embodiment, the movement angle of the second stop block 72 between two adjacent first stop blocks 71 is ninety degrees, which facilitates the positioning of the rotation angle of the second lifting platform 52.

[0072] A support assembly 8 is provided between the first platform 2 and the first lifting platform 51. The support assembly 8 includes a pad 81 and a telescopic support column 82. The telescopic support column 82 is located on the lifting platform. The pad 81 is located on the first platform 2. The top of the pad 81 is used to contact the bottom end of the telescopic support column 82.

[0073] When the first lifting platform 51 moves upward, the overall length of the telescopic support column 82 is adjusted so that the bottom end of the telescopic support column 82 contacts the top of the pad 81, thereby further improving the structural stability of the first lifting assembly 5.

[0074] When the first lifting platform 51 moves downward, the telescopic support column 82 shortens as a whole. In this embodiment, the telescopic support column 82 is a cylinder.

[0075] The first platform 2 is provided with a placement opening. A telescopic support column 82 is inserted into the placement opening. A pad 81 is slidably engaged with the first platform 2. The pad 81 moves on the first platform 2 via a first horizontal drive unit. In this embodiment, the first horizontal drive unit is a cylinder.

[0076] When it is necessary to support the telescopic support column 82, the pad 81 is moved on the first platform 2 to be directly below the telescopic support column 82, and the overall length of the telescopic support column 82 is adjusted so that the pad 81 supports the telescopic support column 82.

[0077] When the first lifting platform 51 moves downward, the pad 81 is moved out of the direct line of the telescopic support column 82, and the telescopic support column 82 is inserted into the placement hole, thereby increasing the moving range of the first lifting platform 51.

[0078] The first platform 2 is provided with a guide bar 83. The guide bar 83 is provided with a guide groove 84. The pad 81 is provided with a guide block. The guide block and the guide groove 84 are slidably engaged. During the movement of the pad 81, the inner wall of the guide groove 84 further guides and limits the pad 81 through the guide block, thereby improving the stability and positional accuracy of the pad 81's movement.

[0079] The implementation principle of a differential assembly workbench according to an embodiment of this application is as follows: First, the differential housing 4 is pre-placed on the differential housing 4 placement area of ​​the second platform 3. The second platform 3 is transported to directly above the first platform 2 via two roller conveyor lines 11. The lifting assembly 5 on the first platform 2 lifts the second platform 3 upwards, causing the second platform 3 to detach from the roller conveyor lines 11, reducing the impact of roller vibration on differential assembly. When it is necessary to rotate the differential housing 4, the operator directly rotates the second platform 3, which drives the differential housing 4 to rotate. After the differential assembly is completed, the lifting assembly 5 is used again to place the second platform 3 on the roller conveyor lines 11, and it is transported to the next process via the roller conveyor lines 11. The positioning pin 6 on the lifting assembly 5 is inserted and engaged with the positioning hole 31 on the second platform 3. When lifting and placing the second platform 3, the positioning pin 6 positions and releases the second platform 3, improving the positional stability of the second platform 3 when moving in the vertical direction. The annular limiting boss on the second lifting platform 52 is engaged with the limiting groove at the bottom of the second platform 3 to further enhance the stability of supporting the second platform 3.

[0080] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
