DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0023] Example 1 like Figures 1 to 7 As shown, an automobile rear axle assembly assembly device includes a supporting plate 1 and: Sliding parts 2, two of the sliding parts 2 are slidably arranged on the top surface of the supporting plate 1; A U-shaped frame 3 is fixedly provided on the sliding portion 2, the axes of the two U-shaped frames 3 are horizontally arranged and coincide with each other, and an arc-shaped plate 4 is rotatably installed on the inner side of the two U-shaped frames 3, and the rotation axes of the two arc-shaped plates 4 are horizontally coaxially arranged, and an arc-shaped mounting groove 23 is provided on the inner wall of the arc-shaped plate 4, and at least two telescopic elements 5 are arranged around the axis in the arc-shaped mounting groove 23, and a mounting block 24 is fixed on the outer peripheral wall of the telescopic element 5, and the mounting block 24 is located in the arc-shaped mounting groove 23 and is detachably connected to the arc-shaped mounting groove 23, and the telescopic end of the telescopic element 5 points to the axis of the arc-shaped plate 4 and is fixed with a pressure plate 6.

[0024] In this embodiment, the rear axle housing 20 includes a differential cavity 201, end covers 203, and half-shaft portions 202 on both sides. The assembly process is as follows: the differential is installed in the differential cavity 201, and after lubricating oil is poured, the end covers 203 are covered. The two half-shafts are respectively inserted into the rear axle housing 20 through the half-shaft portions 202 and connected to the differential power. The half-shafts are mounted with flanges at the ends extending out of the rear axle housing 20. like Figure 5 As shown, during the assembly phase, the half-shaft portions 202 on both sides are placed on the two U-shaped frames 3, with the differential cavity 201 located between the two U-shaped frames 3. The telescopic element 5 pushes the pressure plate 6 to extend, clamping the outer wall of the half-shaft portion 202, and the assembly work begins. Compared to directly placing the rear axle housing 20 on a table for assembly, in this embodiment, the rear axle housing 20 is restrained by the U-shaped frames 3, reducing shaking and making assembly more convenient. like Figure 6 As shown, after the assembly work is completed, the staff can manually move the curved plate 4, and the curved plate 4 rotates in the U-shaped frame 3, driving the rear axle housing 20 to rotate, so as to facilitate inspection around the rear axle housing 20 to confirm whether the product has any defects; during the rotation process, the sealing of the differential cavity 201 can also be tested to see whether the lubricating oil leaks from the end cover 203; The cross section of the semi-axle portion 202 includes circular and rectangular shapes, etc. Figure 5 and Figure 6 As shown, the telescopic element 5 and the mounting block 24 can be moved around the axis in the arc-shaped mounting groove 23 to adjust their position and are fixed by screws. In the initial state, there are three telescopic elements 5, which are evenly distributed in the arc-shaped mounting groove 23. They are more suitable for clamping the semi-axle portion 202 with a circular cross-section, but have a poor fixing effect on the rectangular cross-section. like Figure 7 As shown, when it is necessary to clamp the semi-axial portion 202 of the rectangular cross-section, the telescopic elements 5 located on both sides are moved along the arc-shaped mounting groove 23 toward the opening direction of the arc-shaped plate 4 to ensure that when the pressure plate 6 is extended, it can press the corners of the semi-axial portion 202 of the rectangular cross-section, and the fixing effect is more stable.

[0025] This solution can change the distance between the U-shaped frames 3 on both sides by adjusting the sliding part 2, and is suitable for rear axles of different lengths. By adjusting the extension stroke of the pressure plate 6 by the telescopic element 5, it is suitable for rear axles with half-axles of different diameters. By adjusting the extension position of the telescopic element 5, it can be suitable for half-axle parts 202 with different cross-sectional shapes, thereby improving the versatility of the equipment.

[0026] Example 2 like Figures 1 to 3 As shown, preferably, on the basis of embodiment 1, an arcuate chute 7 is provided on the inner side of the U-shaped frame 3, a slider 8 is fixed on the outer peripheral wall of the arc plate 4, and the slider 8 is slidably located in the arcuate chute 7; One end of the arc-shaped plate 4 extends out of the U-shaped frame 3 and a tooth segment 9 is provided on the outer peripheral wall. A first rotary power source 10 is provided on the sliding portion 2. A gear 11 is fixed on the output shaft of the first rotary power source 10, and the gear 11 is engaged with the tooth segment 9.

[0027] like Figures 1 to 3 As shown, two sets of slide rails 12 are fixed on the supporting plate 1, the central axes of the two sets of slide rails 12 coincide with each other, and the two sliding parts 2 are respectively slidably positioned on the two slide rails 12; A threaded rod 13 is rotatably provided in the slide rail 12 , the sliding portion 2 is sleeved on the threaded rod 13 and threadedly connected to the threaded rod 13 , a second rotational power source 14 is provided on one side of the slide rail 12 , and an output shaft of the second rotational power source 14 is dynamically connected to the threaded rod 13 .

[0028] In this embodiment, the second rotational power source 14 drives the threaded rod 13 to rotate, the threaded rod 13 drives the sliding part 2 to move, and the sliding part 2 converts the rotational motion of the threaded rod 13 into a linear motion along the slide rail 12. The two sliding parts 2 move closer to or away from each other, driving the U-shaped frame 3 to move closer to or away from each other, corresponding to rear axle housings 20 of different lengths.

[0029] In this embodiment, Figure 4 As shown, the U-shaped frame 3 always opens upward, and an arc-shaped chute 7 is provided inside the U-shaped frame 3. The axis of the arc-shaped chute 7 is coaxial with the arc-shaped plate 4. In the initial state, when the opening of the arc-shaped plate 4 is also facing upward, it is convenient to place the rear axle housing 20 into the U-shaped frame 3; Then as Figure 5 As shown, the first rotating power source 10 is a forward and reverse motor, which can drive the gear 11 to rotate forward or reverse. The gear 11 drives the tooth segment 9 to move, and the tooth segment 9 drives the arc plate 4 to rotate. Since the tooth segment 9 does not form a complete 360° gear ring, the gear 11 drives the arc plate 4 to rotate 90° to the left and right, driving the rear axle housing 20 to rotate 90° to both sides for bottom inspection to confirm whether the product has any defects.

[0030] On the basis of this embodiment, if the arc plate 4 is manually moved, it is not restricted by the tooth segment 9 , and the arc chute 7 and the slider 8 cooperate, so that the arc plate 4 can complete a circular motion in the U-shaped frame 3 .

[0031] Example 3 like Figure 1 As shown, preferably, based on embodiment 1-2, a base 15 is included, and a scissor-type lifting bracket 16 is provided on the top surface of the base 15, and the top end of the scissor-type lifting bracket 16 is fixedly connected to the supporting plate 1.

[0032] like Figure 1 As shown, a universal wheel 17 is provided below the base 15 .

[0033] like Figure 1 As shown, a tool box 18 is also provided on the bottom surface of the supporting plate 1 .

[0034] like Figure 1 As shown, an escape groove 19 is provided on the supporting plate 1 , and the escape groove 19 is located between the two sets of slide rails 12 .

[0035] In this embodiment, a limiting slide groove 21 is provided on the inner side of the base 15. One end of the bottom of the scissor-type lifting bracket 16 is hinged in the limiting slide groove 21, and the other end is provided with a connecting column 22. The axis of the connecting column 22 is perpendicular to the limiting slide groove 21 and is slidably installed in the limiting slide groove 21. When the scissor-type lifting bracket 16 is raised or lowered, the connecting column 22 slides in the limiting slide groove 21. When assembling the rear axle housing 20, the scissor-type lifting bracket 16 is used to adjust the height of the support plate 1 to adapt to the heights of workers of different heights; when the assembly is completed, the base 15 is pushed to the bottom of the car chassis by the universal wheel 17 to cooperate with the assembly of the entire vehicle, reducing the labor intensity of the workers in carrying.

[0036] In addition, the tool box 18 stores assembly tools in a unified manner for easy access.

[0037] In addition, during the assembly process of the rear axle housing 20, the avoidance groove 19 can increase the operating space below, making it easier for the staff to perform assembly. Since the differential cavity 201 is located in a larger volume, when the rear axle housing 20 rotates, the avoidance groove 19 can avoid the middle differential position to prevent the rear axle housing 20 from being damaged by impact.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
