[0002] The driver's cab of a traditional rail vehicle is mainly composed of a FRP cover and a metal frame. The metal frame is either pre-embedded and formed integrally with the FRP cover, or by pre-embedding metal connectors in the FRP cover, and then assembling the metal connectors with the metal frame using bolts, rivets, etc., so as to realize the assembly of the FRP cover and the metal frame. The metal frame is then connected to the vehicle body by bolts, welding, etc., and finally the interior decoration parts are installed. The above assembly process usually adopts a vertical installation method with process struts, but the process struts cannot guarantee high-precision installation, and a lot of grinding and assembly processes are required to make up for it, which is inefficient.

The left and right directions of the support rib are determined according to the distance from the outer cover flange. Measure the bonding surface and bonding gap of the support rib. After determining the position, use a C-type clamp to clamp the positioned support rib to the tooling to prevent slippage during the process; after the support rib assembly is adapted, adapt to the floor. When adapting the floor, measure the distance between the support rib assembly and the floor When the spacing between the floor and the positioning inserts of the floor positioning assembly 13 meets the requirements, the floor adaptation is considered complete; when adapting the partition assembly, the partition assembly and the floor are riveted with glue, and the partition positioning assembly 14 is used to locate the relative position of the partition assembly. After positioning, the relative position of the partition assembly to the edge of the floor is measured. After the position is correct, use the holes on the L-shaped metal parts of the partition assembly to punch holes on the floor for positioning, and then take the floor and partition assembly out of the tooling to punch all rivet holes; when adapting the interior assembly, the left and right interior wall panels are used to roughly position the interior wall panels with their own process holes, and then the relative positions of the interior positioning card board, floor and interior assembly are measured. If there is interference, the interference needs to be polished and then measured, and the adaptation and measurement steps are repeated until the gap between the interior assembly and the interior positioning assembly 15 is guaranteed to be within the drawing range.

[0131] After all parts are qualified, the support rib assembly and the floor can be bonded. After bonding, measure the distance again. After confirmation, fix it with tooling and let it stand to solidify. After the support rib assembly and floor are bonded, hand paste is performed to avoid interference with subsequent parts and no operating space. The support rib hand paste area is on both sides of the bonding surface between the left and right support ribs and the outer cover, and the floor hand paste area is on both sides of the contact surface between the floor and the outer cover. After the floor and support rib assembly are hand-pasted, the partition assembly is bonded and riveted, glue is piled on the floor, and the L-shaped metal parts of the partition assembly are infiltrated. Then insert rivets into the pre-assembled rivet holes and rivet. Note to measure the bonding seam before riveting, and control the bonding gap at the rivet to be within 0.2-0.5mm; after the partition assembly is bonded and cured, hand paste is performed, and the hand paste area is the contact surface between the partition assembly and the outer cover; the bonding surface between the interior assembly and the outer cover is large, and there are many bonding parts, so some parts cannot be cleaned in time during the bonding and glue squeezing. Therefore, before bonding, protect the non-bonding area first, pile glue on the outer cover, support rib assembly and floor, and only soak the interior assembly before bonding.

[0132] After the interior trim components are bonded, the flip tool 60 is locked on the outer cover through the waist-shaped hole, and the back plate 61 of the flip tool 60 is lifted. When the driver's cab is moved out of the outer cover positioning tool 11, the base 62 of the flip tool 60 is installed, and the driver's cab is flipped with the help of the base 62.

[0133] After the cab is flipped over, install the console panel, cabinet doors and foot pedals.

[0137] Among them, the first direction may be the up-down direction of the support rib assembly, the second direction may be the front-back direction of the support rib assembly, and the third direction may be the left-right direction of the support rib assembly.

[0138] For example, the support rib positioning insert can be a square tube, which is used to position the support rib assembly up and down and front and back. The left and right directions of the support rib assembly are determined by the engraved lines on the insert. Of course, the left and right directions can also be positioned by adjusting the gap between the outer cover and the support rod.

[0139] The floor positioning assembly 13 includes floor positioning pins and floor positioning inserts. The floor positioning pins are used to position the floor in the first direction and the third direction. The floor positioning inserts are used to contact and abut against a side of the floor away from the supporting rib assembly to position the floor in the second direction.

[0140] The floor locating pins are used to connect with the floor to locate the floor up and down and left and right. The floor locating inserts at the rear end of the floor are used to locate the floor in the front and back directions, so that the floor can be fixed. In addition, the floor is made with four more process holes to facilitate positioning and lifting the driver's cab when completed.

[0141] The partition plate positioning assembly 14 is used to position the relative position of the partition plate assembly and the floor.

[0142] The interior trim positioning assembly 15 includes a plurality of interior trim positioning card plates, each of which is used to position the interior trim assembly on the outer cover.

[0143] After the assembly of other parts is completed, the interior decoration component is hoisted into the driver's cab positioning tool 10, and the interior decoration component is positioned by the shape of the interior decoration component and the outer cover itself, and the interior decoration component is positioned by the interior decoration positioning card, and at the same time, it is checked whether the interior decoration component is placed in place.

[0144] In some embodiments, the cab assembly device further includes a support rib positioning and connecting tool 20 , and the support rib positioning and connecting tool 20 includes a base frame 21 , a first support rib positioning and connecting component 22 , and a second support rib positioning and connecting component 23 .

[0145] Among them, the first support rib positioning connection component 22 is arranged on the base frame 21, and the first support rib positioning connection component 22 is used to locate the support rod of the support rib assembly in the first direction (up and down direction) and the second direction (front and back direction). The first support rib positioning connection component 22 is provided with a second positioning mark, and the second positioning mark is used to locate the position of the support rod in the third direction (left and right direction); the second support rib positioning connection component 23 is arranged on the base frame 21, and the second support rib positioning connection component 23 is used to locate the two support rib bodies of the support rib assembly with the support rod.

[0146] It can be seen that the support rib positioning and connecting tooling 20 is used for bonding the support rib assembly. The first support rib positioning and connecting assembly 22 includes a pair of first support rib positioning inserts. The first support rib positioning inserts have positioning grooves for positioning the support rods in the up and down and front and back directions.

[0147] In some embodiments, the driver's cab assembly device also includes a flip tool 60, which includes a back panel 61 and a base 62. The base 62 is detachably connected to the back panel 61. The back panel 61 is used to be locked and connected to the waist-shaped hole opened on the interior decoration component, and the base 62 is used to allow the driver's cab to flip to a preset angle.

[0148] Specifically, by pre-opening a waist-shaped hole on the interior decoration component, after the driver's cab is assembled, the back plate 61 of the flip tool 60 is first locked and connected to the driver's cab through the waist-shaped hole, and then the driver's cab is lifted off the driver's cab positioning tool 10, and then the base 62 of the flip tool 60 is installed on the back plate 61 and the driver's cab is flipped to a preset angle through the base 62, so as to facilitate the installation of the console panel, cabinet door and foot pedal in the driver's cab.

[0149] In some embodiments, the driver's cab assembly device also includes a transfer tool 70, which is L-shaped. The transfer tool 70 includes a vertical transfer body 71 and a transverse transfer body 72. The vertical transfer body 71 is provided with a first connecting structure 711 at one end away from the transverse transfer body 72. The first connecting structure 711 is used to adapt and connect with the hollow structure of the outer cover headlight. The transverse transfer body 72 is provided with a second connecting structure 721 at one end away from the vertical transfer body 71. The second connecting structure 721 is used to adapt and connect with the mounting hole on the support rib assembly, and the transverse transfer body 72 is also provided with a lifting ear 722.

[0150] It can be seen that the transfer tooling 70 is an L-shaped structure as a whole, which makes full use of the hollow structure of the outer cover headlight and the mounting holes on the top of the support rib assembly, and designs a conformal connection structure. Specifically, the first connection structure 711 and the second connection structure 721 are respectively adapted to connect with the hollow structure of the outer cover headlight and the mounting holes on the support rib assembly. At the same time, lifting ears 722 are arranged on both sides of the cross beams on the top of the transfer tooling 70 to cooperate with the overhead crane for lifting and transfer.

[0151] Such an arrangement, using a vertical transfer tool 70, with the lifting point set at the front end of the driver's cab, can effectively ensure the fit between the rear end of the driver's cab and the front end of the vehicle body, and can quickly realize the installation and disassembly of the vertical transfer tool 70, thereby improving the assembly efficiency.

[0152] In some embodiments, the cab assembly device further includes an interior trim positioning and connection tool 50, and the interior trim positioning and connection tool 50 is used to assist in completing the positioning and assembly of the interior trim components.
