Description

Technical Field

[0001] This utility model relates to a flexible assembly device for a rear drive axle of an automobile, belonging to the field of automotive parts processing and manufacturing technology. Background Technology

[0002] As a key component of the automotive chassis system, the rear drive axle's main function is to support the wheels, connect the rear wheels, and provide driving, deceleration, and differential functions when the vehicle is in motion.

[0003] The rear drive axle varies greatly depending on the customer and the vehicle model. To better serve customers and be compatible with more product series, flexible assembly is crucial. A good flexible design can be compatible with more products, reduce investment, reduce changeover time, and improve production efficiency.

[0004] The existing assembly device structure involves symmetrically welding V-shaped blocks on both sides of the base plate. The V-shaped blocks support the rear drive axle housing. The disadvantage is that the V-shaped blocks are fixed on the base plate, and the support point position is fixed, so the position cannot be adjusted. Different rear drive axle parts are in different positions, which causes interference from the welded parts on the support block. There is also a risk of scratches and damage to the paint and welded parts of the rear drive axle during placement and flipping. Utility Model Content

[0005] The purpose of this invention is to provide a flexible assembly device for automotive rear drive axles, which is particularly suitable for production lines that are compatible with multiple product types. This device reduces changeover time, improves production efficiency, and reduces the labor intensity of operators.

[0006] The technical solution adopted by this utility model is: a flexible assembly device for a rear drive axle of an automobile, characterized in that: it includes a rear drive axle following unit and a rear drive axle support unit; the rear drive axle following unit includes a following base plate, on which two sets of linear guide rails and several lifting lugs are provided; a stop pin is also provided on the following base plate; the rear drive axle support unit includes a sliding support plate, on which a support block that cooperates with the workpiece is provided above the sliding support plate, and on which a slider that cooperates with the linear guide rails is provided below the sliding support plate; a limit pin is also provided on the sliding support plate.

[0007] Furthermore: a stop pin on the accompanying base plate serves to limit the movement of the rear drive axle support unit, and the stop pin is threadedly connected to the base plate.

[0008] Furthermore, the support block is provided with an inverted triangular groove.

[0009] Further: The lifting lugs are threadedly connected to the accompanying base plate.

[0010] Furthermore, the accompanying base plate is provided with multiple limiting holes that cooperate with the limiting pins.

[0011] Furthermore: the sliding support plate is Z-shaped, and the limiting pin is inserted into the bottom edge of the Z-shape.

[0012] The beneficial effects of this utility model are as follows: Its structural design is simple and reasonable, and the device has strong versatility. By lifting the limiting pin, the drive axle support device can slide on the linear guide rail, thereby achieving rapid product changeover. This results in fast changeover speed, high efficiency, cost savings, and high production efficiency. Simultaneously, it achieves accurate positioning, reducing scratches and dents on the rear drive axle paint and improving paint quality. The utility model's reasonable structural design and strong versatility allow it to be compatible with more products, shortening changeover time and tooling investment, saving manufacturing costs, and improving production efficiency.

[0018] according to Figures 1-3 The specific structure of this utility model is described in detail. A flexible assembly device for a rear drive axle of an automobile includes a rear drive axle following device 1 and a rear drive axle support device 2. Its technical features are: the rear drive axle following device is composed of a following base plate, a linear guide rail, a stop pin, and a lifting lug; the rear drive axle support device is composed of a support block, a sliding support plate, a limit pin, and a slider.

[0019] The rear drive axle flexible assembly device has a symmetrical structure and is supported on the rear drive axle housing tube. Different product series can be changed by adjusting the position of the rear drive axle support device. The linear guide rail 4 is installed in the guide rail groove of the accompanying base plate 3 and fixed with bolts; the stop pin 5 is connected to the hole on the accompanying base plate 3 by an interference fit; the lifting lug 6 is connected to the accompanying base plate 3 by a thread; the rear drive axle support device is slidably connected to the linear guide rail 4 by a slider 10; the support block 7 is connected to the sliding support plate 8 by welding; the sliding support plate 8 is connected to the slider 10 by bolts; the limiting pin 9 is placed in the limiting hole of the sliding support plate 8 and the two are slidably engaged. Lifting the limiting pin pushes the sliding support plate, causing the slider to slide along the linear guide rail for adjustment and change of shape. In this utility model structure, the slider is provided with an inverted groove, which can be fastened to the linear guide rail and slidably engaged with the top surface of the linear guide rail, while both sides are limited by the linear guide rail. This structure can achieve good fit to ensure positional stability, and at the same time, the slider can be directly removed for quick replacement.

[0020] The working process of this utility model structure is as follows:

[0021] During adjustment and model change, lift the limit pin to push the sliding support plate, causing the support block to slide along the linear guide rail until it is adjusted into the limit hole of the corresponding model, thus completing the model change. Place the rear drive axle assembly on the support block to install the rear drive axle.
