DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0021] A rear axle installation tool for an automobile comprises a lifting platform 1, a support column 2 is fixedly installed at the center position of the upper surface of the lifting platform 1, a lifting plate 21 is fixedly installed on the upper surface of the support column 2, two support platforms 3 are symmetrically fixedly installed on the upper surface of the lifting platform 1, and the two support platforms 3 are respectively located on the left and right sides of the support column 2, a U-shaped lifting groove 31 is opened on the upper surface of the support platform 3, and a mounting groove 32 is opened through the front surface of the support platform 3, two connecting grooves 33 are symmetrically opened between the U-shaped lifting groove 31 and the mounting groove 32, V-shaped clamping rods 4 are rotatably installed in the connecting grooves 33 through a rotating shaft, an electric telescopic column 5 is fixedly installed in the mounting groove 32, a fixing plate 51 is fixedly installed on the upper surface of the electric telescopic column 5, connecting grooves 511 are opened at the front and rear ends of the fixing plate 51, connecting rods 52 are rotatably installed in the connecting grooves 511 through a rotating shaft, and one end of the connecting rod 52 away from the fixing plate 51 is rotatably connected to the lower end of the corresponding V-shaped clamping rod 4 through a rotating shaft;

[0022] like Figure 4 As shown, when the electric telescopic column 5 is extended, it can drive the fixing plate 51 to move upward, and the fixing plate 51 drives the lower end of the V-shaped clamping rod 4 to move outward through the connecting rod 52, so that the upper end of the V-shaped clamping rod 4 is turned inward, as shown in FIG. Figure 2 As shown, when the upper ends of the two V-shaped clamping rods 4 come into contact with the outer surface of the shaft of the rear axle of the automobile placed in the U-shaped lifting groove 31, they can be clamped and fixed. After the installation of the rear axle shell of the automobile is completed, the electric telescopic column 5 is retracted, and under the linkage of the fixing plate 51 and the connecting rod 52, the upper end of the V-shaped clamping rod 4 is driven to flip outward to release the fixation. After release, the lifting platform 1 is lowered to the lifting position, and the tooling can be pulled out of the lifting position of the rear shell of the automobile as a whole.

[0023] In order to further enhance the clamping performance of the V-shaped clamp rod 4 on the rear axle of the vehicle, Figure 4 As shown, an arc-shaped clamping portion 41 is provided at the top inner end of the V-shaped clamping rod 4, and the arc-shaped clamping portion 41 can be used to increase the contact area with the end of the shaft of the rear axle of the automobile, thereby enhancing the clamping performance.

[0024] It should be noted that if Figure 1 As shown, the lifting platform 1 includes a base 11, a manual jack 12 is fixedly installed at the center of the upper surface of the base 11, a support plate 13 is fixedly installed on the upper surface of the manual jack 12, and the support column 2 and the support platform 3 are fixedly installed on the upper surface of the support plate 13. The support height of the manual jack 12 can be manually adjusted to adjust the support height of the entire tooling;

[0025] To ensure the stability of the support plate 13 during lifting and lowering, Figure 1As shown, four directional rods 14 are symmetrically fixedly installed on the upper surface of the base 11. After the support plate 13 is slidably set between the four directional rods 14, the directional rods 14 can be used to ensure that the support plate 13 is vertically lifted and lowered under the drive of the manual jack 12, thereby ensuring its stability during lifting.

[0026] To facilitate the overall movement of the tooling, Figure 1 As shown, four self-locking universal wheels 111 are fixedly installed on the lower surface of the base 11. After the tooling is moved as a whole to a specified position, it can be positioned by the locking structure of the self-locking universal wheels 111 themselves.

[0027] Finally, in order to facilitate the synchronous clamping of the shafts at both ends of the automobile axle housing and improve the installation efficiency, such as Figure 1 As shown, a synchronous lifting controller body 6 is fixedly installed on the upper surface of the support plate 13. After the synchronous lifting controller body 6 is electrically connected to the two electric telescopic columns 5 through cables and the two electric telescopic columns 5 are powered on, the extension or contraction of the two electric telescopic columns 5 can be synchronously controlled by the synchronous lifting controller body 6, and the two operate synchronously, thereby improving the installation efficiency of the automobile axle housing.

[0028] In actual use of the utility model, Figure 2 As shown, first place the center of the automobile axle housing on the upper surface of the lifting plate 21 for support, and at the same time place the shaft bodies at both ends of the automobile axle housing in the corresponding U-shaped lifting grooves 31. Next, the two electric telescopic columns 5 are synchronously controlled to extend through the synchronous lifting controller body 6, driving the upper end of the V-shaped clamping rod 4 to flip inward, and the shaft bodies at both ends of the automobile axle housing are fixed by the arc-shaped clamping part 41. Subsequently, the workpiece is pushed to the installation position of the automobile axle housing with the help of the self-locking universal wheel 111, and the lifting height of the tooling is adjusted by the manual jack 12 until it reaches the appropriate installation height for installation. After the installation is completed, the two electric telescopic columns 5 are synchronously controlled to contract, driving the upper end of the V-shaped clamping rod 4 to flip outward to release the fixation. Subsequently, the lifting height of the tooling is lowered by the manual jack 12, so that the U-shaped lifting groove 31 is separated from the automobile axle housing, and finally, the tooling is moved out of the installation area as a whole.
