[0003] Taking a certain vehicle model as an example, six boxes of power batteries are arranged on the bottom battery installation bracket. The front and rear span of the bracket is 3 meters, the left and right span is 2.5 meters, and the total mass is 1200 kilograms. There is no lifting device on the original tooling. Due to the limitation of the structure in the middle section of the bracket, the installation screws cannot be installed. Only the screws around can be pre-tightened first. Since the horizontal and radial spans of the bottom battery bracket are relatively large, the weight of the battery causes serious downward hanging in the middle section of the bracket, and the fixing screws in the middle section of the bracket cannot be installed. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a mobile battery installation tooling. Place the assembled bottom power battery bracket assembly on this tooling. The bottom of the tooling is equipped with four wheels for convenient mobile operation. According to the installation position of the batteries at the bottom of the vehicle, adjust the position of the tooling so that the battery bracket assembly on the tooling can accurately find the fixing points, adjust the hydraulic lifting device in the middle, control the height of the battery bracket assembly to install the batteries, and solve the problem that the screws in the middle section of the bottom battery bracket cannot be installed.

[0005] The purpose of the utility model is achieved by the following technical solutions: This mobile battery installation tooling includes a main body frame and a hydraulic lifting device. The top of the main body frame serves as an assembly table for placing and positioning the battery bracket assembly. A lifting area is arranged in the middle of the main body frame, and the hydraulic lifting device is installed in this lifting area. Drive the lifting plate at the top of the hydraulic lifting device through hydraulic pressure, so that the lifting plate extends out of the assembly table and jacks up the middle of the battery bracket assembly, driving the power battery assembly installed on the battery bracket assembly to move up and down, thereby adjusting the installation position of the power battery assembly relative to the vehicle.

[0006] As a further technical solution, positioning bolts are arranged at the four corners of the assembly table for positioning the battery bracket assembly.

[0007] As a further technical solution, the battery bracket assembly and the power battery assembly are fixedly connected by fixing bolts.

[0008] As a further technical solution, universal wheels are arranged at the four corners of the bottom of the main body frame.

[0009] As a further technical solution, avoidance spaces are provided at positions corresponding to the top and side surfaces of the jacking area on the main body frame, and the jacking plate freely rises and falls through the avoidance space at the top of the main body frame; the pedal of the hydraulic jacking device faces the avoidance space on the side surface of the main body frame for stepping on.

[0010] As a further technical solution, handrails are provided on the main body frame.

[0011] As a further technical solution, the main body frame is made of Q235 square tubes welded by CO2 shielded arc welding.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. The entire battery bracket assembly is installed on the subassembly tabletop of the main body frame and positioned by positioning bolts. The universal wheels at the bottom of the main body frame facilitate the movement operation. According to the installation position of the battery at the bottom of the vehicle, the position of the tooling is adjusted so that the battery bracket assembly on the tooling can accurately find the fixed points.

[0014] 2. A hydraulic jacking device is provided in the middle of the main body frame. The jacking plate is controlled to rise and fall by the pedal, thereby driving the battery bracket assembly and the power battery assembly to perform lifting movement, and controlling the height of the battery bracket assembly to facilitate the installation of the battery.

[0015] 3. The battery bracket assembly and the power battery assembly are connected by fixing bolts to prevent the battery from falling off. Description of the Drawings
