DETAILED DESCRIPTION

[0022] The specific content of the utility model will be further described below:

[0023] The utility model is used for the welding positioning device for the through cabin of the C-type motor home, the C-type motor home is provided with a chassis 2 and a box body 1 constituting a motor home vehicle body, and a front through cabin 5 is welded and installed on the rear side opening of a cab 6.

[0024] The device positioning structure comprises a rear fixed rod 9, a bottom bracket 10, a front positioning bracket 11 and a side triangular connecting rod 12. The front positioning bracket 11 is fixed at the front of the bottom bracket 10. The side triangular connecting rod 12 connects the rear of the bottom bracket 10 and the top of the front positioning bracket 11. The front side of the front positioning bracket 11 is flush with the front end edge of the chassis.

[0025] The fixed rod, the bottom bracket 10, the front positioning bracket 11 and the side triangular connecting rod 12 are made of rectangular tubes. The rear fixed rod 9, the bottom bracket 10, the front positioning bracket 11 and the side triangular connecting rod 12 are fixedly integrated by welding. The front positioning bracket 11 of the device is a rectangular frame structure, with a space left in the middle and a front through cabin 5 embedded and fixed therein.

[0026] The rear fixed rod 9 is fixed on the chassis by a detachable fixing member. The bottom bracket 10 is arranged on the chassis in front of the rear fixed rod 9 and is fixed on the chassis by a detachable fixing member.

[0027] The side of the front through cabin 5 is in the same plane as the side of the front positioning bracket 11. The rear end surface of the front through cabin 5 is flush with the front side of the front positioning bracket 11. The front through cabin 5 is connected to the front positioning bracket 11 by a detachable structure.

[0028] The front end of the front through cabin 5 is welded on the rear side opening of the cab 6. The rear end of the rear through cabin 4 is fixed on the opening of the front box plate 7 of the box body 1. The rear through cabin 4 is connected to the front through cabin 5 by a flexible cylinder seal after abutting.

[0029] The detachable fixing member in the device is a C-shaped clamp. The chassis is provided with a transversely uppermost auxiliary beam 13. The rear fixed rod 9 is laid on the auxiliary beam 13. The C-shaped clamp clamps the auxiliary beam 13 and the rear fixed rod 9 to fix them.

[0030] The use process of the device is as follows:

[0031] First, the C-shaped clamp is used to fix and connect the concentrated rear fixed rod of the device and the auxiliary beam 13 together by the C-shaped clamp. The position of the bottom bracket on the chassis is pre-positioned. Then, the bottom bracket is placed, and the vertical surface of the front positioning bracket is ensured to be flush with the front side of the chassis. The middle space of the front positioning bracket is coincided with the opening position on the front box plate of the box body to be installed.

[0032] The rear end surface of the front through cabin is aligned with the front side of the front positioning bracket. The upper and lower side surfaces and the left and right side surfaces of the front through cabin are aligned with the middle space of the front positioning bracket. Then, the front end of the front through cabin is welded on the rear side opening of the cab to ensure the correct welding position of the cab and the front through cabin 5. Thus, the front box plate of the box body is aligned after the installation of the front through cabin and the rear through cabin.

[0033] The device is separated from the bottom bracket and the rear fixed plate on the chassis after the front-through cabin 5 is welded, the whole device is disassembled and moved away, then the front side plate and the rear-through cabin of the box body are installed, and the flexible connecting cylinder is installed to connect the front-through cabin and the rear-through cabin, so that sealing is realized.
