In this embodiment, the threaded support post 20 is disposed at a position on the base 11 close to the clamping structure 13, the air compression assembly can supply air to the air cylinder 12, the air cylinder 12 can drive the clamping structure 13 connected to the air cylinder 12 to be in a clamping state after the air supply, and the clamping structure 13 can clamp the threaded support post 20 in the clamping state to fix the threaded support post 20, so as to prevent the threaded support post 20 from shifting, slipping, and the like. After the assembly is completed, the air cylinder 12 is controlled to vent, so that the clamping structure 13 is released from the clamping state to loosen the threaded support post 20.

The pneumatic preassembly tool 10 provided by the embodiment can firmly clamp the threaded support column 20 by using the cooperation of the air cylinder 12, the air compression assembly and the clamping structure 13, and effectively avoids the threaded support column 20 from slipping or shifting in the assembling process.

In this embodiment, optionally, the air cylinder 12 on the base 11 may include a plurality of air cylinders, and each air cylinder 12 is connected with a clamping structure 13, which may be used to clamp a plurality of threaded support posts 20. Wherein, the number of the air cylinders 12 and the clamping structures 13 can be set according to the number of the threaded support columns 20 required for assembling the battery module, for example, when the number of the threaded support columns 20 required for assembling is two, two air cylinders 12 are correspondingly set, and the clamping structures 13 are set on each air cylinder 12. Alternatively, the number of cylinders 12 may be three or four, and fig. 2 shows three cylinders 12.

In addition, the pneumatic preassembly tool 10 further comprises a second support frame 112 disposed at the edge of the base 11, and the second support frame 112 is used for supporting the battery module when the battery module is disposed in the pneumatic preassembly tool 10. Specifically, when the ABS panel 30 of the battery module is placed on the base 11, the second support bracket 112 on the base 11 supports the edge of the ABS panel 30, thereby supporting the ABS panel 30 for assembly.

In this embodiment, the base 11, the first supporting frame 111 and the second supporting frame 112 of the pneumatic preassembly tool 10 can be made of plastic materials.

In this embodiment, the air compression assembly includes an air compressor and an air pipe, wherein, the one end of air pipe is connected with the air compressor, and the other end is connected with cylinder 12, and air compressor accessible trachea admits air to cylinder 12 to make cylinder 12 drive clamping structure 13 be the clamping state.

Optionally, a solenoid valve is also provided on the air pipe for controlling the passage between the air compressor and the cylinder 12. For example, when the solenoid valve is opened, an air pipe between the air compressor and the cylinder 12 is opened, and the air compressor can supply air to the cylinder 12 through the air pipe. When the solenoid valve is closed, the air pipe between the air compressor and the cylinder 12 is closed, the air compressor stops charging the cylinder 12, the cylinder 12 stops driving the clamp structure 13, and the clamp structure 13 releases the clamped state.

Referring to fig. 6, the pneumatic preassembly tool 10 is illustrated as including three cylinders 12, wherein the three cylinders 12 are connected in parallel and then connected to the solenoid valves. The threaded support posts 20 can be opened or clamped simultaneously by controlling the on/off of the solenoid valves.

The two air outlets are respectively connected with each air cylinder 12 through air pipes, and the air inlet is communicated with an air compressor through the air pipes. When the air compressor works, after the electromagnetic valve is controlled to be opened, the air compressor can inflate through the air inlet of the electromagnetic valve and can intake air to each air cylinder 12 through the air outlet of the electromagnetic valve. When the work is stopped, the gas in the gas pipe is discharged through the exhaust port of the electromagnetic valve.

Referring to fig. 5 again, in the present embodiment, the clamping structure 13 includes a connecting member 131 and a chuck 132, one end of the connecting member 131 is connected to the cylinder 12, and the other end is connected to the chuck 132, wherein the clamping structure 13 includes a pair of connecting members 131, which are disposed opposite to each other. The pair of chucks 132 of the clamp structure 13 are provided to face each other. A pair of collets 132 may be used to contact the threaded support post 20 to retain the threaded support post 20 in the inflated state of the cylinder 12.

Wherein, the outer wall of the threaded support post 20 is provided with a groove 21, and the clamping structure 13 can clamp the threaded support post 20 by clamping the clamping head 132 in the groove 21 of the threaded support post 20.

Optionally, the cylinder 12 includes a cylinder body 121 and a sliding block 122 disposed on the cylinder body 121, and the connecting member 131 may be connected to the cylinder 12 through the sliding block 122, and is driven by the sliding block 122 to be in a clamping state or a contact clamping state.
