Description

Technical Field

[0001] The present application relates to the technical field of rail vehicles, and in particular to a driver's cab assembly method and a driver's cab assembly device. Background Art

[0002] The driver's cab of a traditional rail vehicle primarily consists of a fiberglass outer casing and a metal frame. The metal frame is either pre-embedded and integrated with the fiberglass outer casing, or by pre-embedding metal connectors within the fiberglass outer casing. The metal connectors are then assembled to the metal frame using bolts and rivets. The metal frame is then connected to the vehicle body through bolts and welding, and finally, the interior trim is installed. This assembly process typically utilizes a vertical installation method with process struts. However, process struts cannot guarantee high-precision installation and require extensive grinding and lapping to correct the problem, resulting in low efficiency.

[0003] Compared to traditional cabs, today's carbon fiber composite cabs consist not only of an exterior cover but also a floor, support ribs, interior components, and equipment mounting interfaces. A foam core replaces the metal skeleton, with pre-embedded metal parts molded integrally with the exterior cover. Components are primarily connected using structural adhesive and rivets, requiring higher precision. The thickness of the structural adhesive layer and the rivet gap are typically around 0.3mm. Conventional vertical assembly processes are no longer suitable for assembling carbon fiber composite cabs.

[0086] It should be noted that the driver's cab provided in the embodiments of this application is a carbon fiber composite cab, comprising an outer cover, a support rib assembly, a floor, a partition assembly, and an interior assembly. The outer cover and floor are connected by adhesive riveting, with hand-layup reinforcement; the floor and partition assembly are connected by adhesive riveting; the outer cover and support rib assembly are connected by secondary adhesive bonding, with partial hand-layup reinforcement; and the outer cover and interior assembly are connected by adhesive riveting.

[0087] The cab positioning tool 10 mainly includes an outer cover positioning assembly 11, a support rib positioning assembly 12, a floor positioning assembly 13, a partition positioning assembly 14, and an interior positioning assembly 15.

[0094] Pre-install the interior trim components on the support rib components, floor and outer cover to ensure that the interior trim components fit the support rib components, floor and outer cover.

[0095] It should be noted that before pre-installing the support rib assembly, floor, partition assembly and interior assembly, the support rib assembly, partition assembly and interior assembly are also included in the independent assembly process. The following details:

[0096] Before the step of pre-installing the support rib assembly on the outer cover, the step further includes:

[0097] Positioning the support rod of the support rib assembly through the first support rib positioning connection assembly 22 of the support rib positioning connection fixture 20;

[0098] Position the two support rib bodies of the support rib assembly through the second support rib positioning connection assembly 23 of the support rib positioning connection tool 20;

[0099] The two support rib bodies are connected to the support rod to form a support rib assembly.

[0100] In other words, the support rib positioning and connection tool 20 is used to assist in the positioning and assembly of the support rib assembly. The support rib assembly includes a support rod and two support rib bodies. The support rib positioning and connection tool 20 includes a base frame 21, a first support rib positioning and connection assembly 22, and a second support rib positioning and connection assembly 23. The first support rib positioning and connection assembly 22 and the second support rib positioning and connection assembly 23 are mounted on the base frame 21. The first support rib positioning and connection assembly 22 is used to position the support rod of the support rib assembly, while the second support rib positioning and connection assembly 23 is used to position the two support rib bodies of the support rib assembly. After positioning is completed, the two support rib bodies are connected to the support rod to form the overall structure of the support rib assembly.

[0101] Of course, according to actual needs, both support rib bodies can be connected to the support rod by bonding.

[0102] Before the steps of pre-installing the interior trim components on the support rib components, the floor and the outer cover, the steps also include:

[0103] Positioning the console of the interior component by the console positioning assembly 51 of the interior positioning connecting fixture 50;

[0105] The console frame of the interior component is positioned and clamped respectively by the console frame positioning component 54 and the console frame clamping component 55 of the interior positioning connecting tool 50 .

[0106] In other words, the interior positioning and connection tool 50 assists in the positioning and assembly of the interior components. Specifically, the positioning and assembly of the interior components primarily involves the positioning and bonding of the left and right interior wall panels, the console, and the console frame. The interior positioning and connection tool 50 primarily comprises a console positioning assembly 51, a wall panel support assembly 52, a wall panel positioning structure 53, a console frame positioning assembly 54, and a console frame clamping assembly 55. The console positioning assembly 51 is used to position the console of the interior component, the wall panel support assembly 52 and the wall panel positioning structure 53 are used to support and position the interior wall panels of the interior component, and the console frame positioning assembly 54 and the console frame clamping assembly 55 are used to position and clamp the console frame of the interior component.

[0107] In the assembly of the partition assembly, the partition positioning and connecting tool is mainly used for the bonding assembly of the partition assembly, and the partition positioning and connecting tool is set according to the structure of the partition assembly and mainly includes partition positioning surfaces for limiting the up-down, left-right and front-back directions of the partition. The partition assembly has two types, namely a left partition assembly and a right partition assembly. The left partition assembly is bonded and assembled by using the left partition positioning and connecting tool 30, and the left partition positioning and connecting tool 30 is provided with left partition positioning surfaces 31 for limiting the up-down, left-right and front-back directions of the left partition assembly. The right partition assembly is bonded and assembled by using the right partition positioning and connecting tool 40, and the right partition positioning and connecting tool 40 is provided with right partition positioning surfaces 41 for limiting the up-down, left-right and front-back directions of the right partition assembly.

[0108] After the cab is completely assembled, in order to facilitate the turning of the cab, the installation of the console panel, the cabinet door and the footrest on the turned cab is also needed. Therefore, the cab needs to be turned by a preset angle through the turning tool 60. The specific process includes:

[0109] After the step of preassembling the interior component on the support rib assembly, the floor and the outer cover, it further includes: opening a waist-shaped hole on the interior component;

[0110] After the step of positioning the interior component by the interior positioning assembly 15 of the cab positioning tool 10 and connecting the interior component to the support rib assembly, the floor and the outer cover, it further includes:

[0111] The back plate 61 of the turning tool 60 is locked and connected to the cab through the waist-shaped hole;

[0114] The cab is turned by a preset angle through the base 62;

[0115] The console panel, the cabinet door and the footrest are installed on the cab.

[0116] It can be understood that by pre-opening the waist-shaped hole on the interior component, after the cab is completely assembled, the back plate 61 of the turning tool 60 is locked and connected to the cab through the waist-shaped hole, then the cab is lifted away from the cab positioning tool 10, after that the base 62 of the turning tool 60 is installed on the back plate 61 and the cab is turned by a preset angle through the base 62, finally the console panel, the cabinet door and the footrest are installed on the cab.

[0125] The steps of positioning the partition assembly by the partition positioning assembly 14 of the cab positioning tool 10 and connecting the partition assembly to the floor and the outer cover include:

[0126] Fixing the partition assembly and the outer cover by gluing and riveting the second connecting piece;

[0127] The partition assembly is connected to the contact wall surface of the outer cover by a hand lay-up process.

[0128] In this embodiment, the left and right partition assemblies are positioned using the partition positioning assembly 14 of the cab positioning tool 10. The left and right partition assemblies and the outer cover are both fixed by gluing and riveting with a second connecting piece. After gluing, they are further fixed by a hand lay-up molding process. The hand lay-up area mainly includes the contact wall surface between the partition assembly and the outer cover.

[0129] The following describes the specific assembly process of the driver's cab:

[0130] When adapting the outer cover, stick a protective film on the processed outer cover, and use the square tube to hang it into the outer cover positioning component 11. Reserve a 1mm gap between the positioning insert on the outer cover positioning component 11 and the product, and before placing the outer cover, pad the positioning insert and support insert of the outer cover positioning component 11 with a 1mm silicone gasket to prevent the insert from hitting the product and causing damage; after the outer cover is adapted, the support rib assembly is hoisted in and positioned with the support rib positioning component 12. The support rib positioning component 12 positions the support rib in the front and back and up and down directions. 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-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 support rib assembly and the floor The floor is considered to be adapted when the gap between the floor and the positioning inserts of the floor positioning assembly 13 meets the requirements; when adapting the partition assembly, the partition assembly and the floor are glued and riveted, 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 from 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 and 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 plate, floor and interior assembly are measured. If there is interference, the interference needs to be polished and then measured. Repeat the adaptation and measurement steps 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 adapted to the specifications, the support rib assembly and the floor can be bonded. After bonding, the distance is measured again. After confirmation, it is fixed with tooling and left to solidify. After the support rib assembly and the floor are bonded, hand-stitching is performed to avoid interference with subsequent parts and no operating space. The support rib hand-stitching area is on both sides of the bonding surface between the left and right support ribs and the outer cover, and the floor hand-stitching 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-stitched, the partition assembly is bonded and riveted, glue is piled on the floor, and the L-shaped metal parts of the partition assembly are soaked. Then insert rivets into the pre-arranged rivet holes and rivet. Note that the bonding seam should be measured before riveting, and the bonding gap at the riveting point should be controlled 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. Therefore, some parts cannot be cleaned in time during the bonding and extrusion. Therefore, the non-bonding area should be protected before bonding, and glue should be applied to the outer cover, support rib assembly and floor. The interior assembly is only soaked and then bonded.

[0132] After the interior 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.

The support rib positioning insert is provided with a first positioning scale line, which is used to position the support rib assembly in a third direction, which is perpendicular to both the first direction and the second direction.

[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 positioning can also be achieved by adjusting the gap between the outer cover and the support rod.

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

[0140] Floor locating pins connect to the floorboards to position them vertically and horizontally. Four floor locating inserts at the rear end of the floorboards position them forward and backward, securing the floor. Additionally, four additional holes are provided in the floorboards to facilitate positioning and lifting the cab upon completion.

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

[0142] The interior trim positioning assembly 15 includes a plurality of interior trim positioning card plates, each of which is used to locate the position of 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 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 connection tool 20 , which includes a base frame 21 , a first support rib positioning and connection assembly 22 , and a second support rib positioning and connection assembly 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 position 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 scale line, and the second positioning scale line is used to position 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 position 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 rod in the up and down and front and back directions. The second support rib positioning and connecting assembly 23 includes two pairs of second support rib positioning inserts, one pair of which is short support rib positioning inserts, and the other pair is long support rib positioning inserts. Any short support rib positioning insert and long support rib positioning insert are provided with positioning elements (such as positioning clamps or positioning calipers, etc.) for positioning the left and right support ribs in the left and right directions.

[0147] In some embodiments, the driver's cab assembly device also includes a flipping 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 lock and connect with the waist-shaped hole opened on the interior component, and the base 62 is used to allow the driver's cab to flip to a preset angle.

[0148] Specifically, by pre-opening waist-shaped holes on the interior components, after the driver's cab is assembled, the back panel 61 of the flip tool 60 is first locked and connected to the driver's cab through the waist-shaped holes, 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 panel 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 footrest 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, making full use of the hollow structure of the outer cover headlight and the mounting holes on the top of the support rib assembly, and designing 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 uses a vertical transfer tool 70, with the lifting point set at the front end of the driver's cab, which 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 positioning and connection tool 50 , which is used to assist in completing the positioning and assembly of interior components.

[0153] Specifically, the interior positioning and connection tooling 50 includes a console positioning assembly 51, a wall panel support assembly 52, a wall panel positioning structure 53, a console frame positioning assembly 54, and a console frame clamping assembly 55.

[0154] In this way, the interior positioning and connecting tooling 50 can be used to assist in completing the positioning and bonding of the interior components.

[0155] To sum up, after all the components are completed, the surface of the components is protected and then the overall assembly is carried out in sequence. The overall assembly process is as follows:

[0156] Protect the surface of components - prepare the assembly site and tools - hoist the outer cover into the driver's cab and position it with tool 10 - position the outer cover - pre-install the support rib assembly - pre-install the floor - pre-install the partition assembly - pre-install the interior assembly - open waist-shaped holes in the interior assembly - glue the support rib assembly - glue the floor - hand-lay up the support rib assembly and the floor - glue + rivet the partition assembly - hand-lay up the partition assembly - glue + rivet the interior assembly - flip the driver's cab - rivet the outer cover window - install the cabinet door - install the footrest - clean up.

[0157] The cab assembly method and device of the present application adopts horizontal integrated assembly, which has the following main advantages over traditional vertical assembly:
