Abstract

Invention relates to a device for assembling, tuning, and testing motor vehicles. Automobile factories are provided with assembly lines, along which components are delivered to an automobile that is to be produced, are assembled, and further processed by humans or robots as required. The automobiles that are to be produced are continuously moved on wheels at the end of the assembly lines by means of chain-driven, rope-driven, or belt-driven apron conveyors. The aim of the invention is to create a device for assembling motor vehicles, which can be mounted anywhere in a flat ball without modifying the ceiling or floor and can be transported. Said aim is achieved by the fact that the inventive device can be assembled from individual transportable, modular, interconnectable components which can be mounted on a flat surface without using pits or creating Boor load. Said device encompasses the conveying mechanisms and assembly units for the motor vehicles that are to be assembled. Disclosed is an embodiment with suspended conveyors for the motor vehicles and different vehicle test stands that touch the wheels.

Description

conveyor line, assembly of units, transportation and assembly of automobile components (doors, instrument panels, engines, seats, front end, wheels, etc.), as well as social devices and logistics. Due to this, high flexibility is realized, since the assembly processes can be carried out consistently and flexibly in accordance with the requirements for the products, and there are no restrictions regarding transport equipment (for example, when changing the model), restrictions regarding the presence of notches (for example, at a "higher level"), as well as restrictions regarding the building (for example, regarding statics, space requirements). Also, the time required for the implementation of such an assembly line is significantly lower, since the modules are delivered already pre-assembled, there is no need for pre-installation of steel structures and planning or execution of notches, there are no transmission nodes in transport equipment (only the transport system), there is a small complexity with a small number of connections, resulting in a fairly short planning time. Less complexity will lead to greater transparency, better overview and better communication without fear of negative impacts on quality.

In one embodiment of the invention, means are provided for connecting power lines passing through individual modules.

This additionally speeds up assembly line installation. If, as a result of the connection of individual modules, feed lines (for current, compressed air, etc.) passing in the axial direction are also connected, then the long-term connection of individual units located in the assembly line to similar feed lines and associated with this is the danger of erroneous or incorrect connection, as well as the danger of injury from these lines.

One better embodiment of the invention is that the transport device is made in the form of a device for transporting cars in a hanging position. and At the same time, the means for the hanging transportation of cars are already made in separate modules, so that there is no need to fix these transport devices on the ceiling of the workshop.

According to the invention, it is provided that the device contains a final assembly section.

At the site of final assembly, wheels are usually installed on the car and functional tests are carried out (tests on acceleration, switching, braking, as well as light tests, etc.). This can also be implemented within the device according to the invention.

In one of the best embodiments of the invention, it is provided that the device contains a test stand, and the car is located on the test stand in a hanging position, and the wheels of the car are made with the possibility of being driven into rotation or with the possibility of braking with the help of side-acting on the wheels, supplied with an electric drive of the elements of the test stand on rolling, braking and ABS.

Thus, even when transporting cars in a hanging position, the section of the final assembly can be passed with the functional tests provided for there, and in addition, the above-mentioned disadvantages of roller test stands are eliminated.

According to one embodiment of the invention, the electrically driven elements affect the tires.

According to another embodiment of the invention, the elements with an electric drive are made with the possibility of influencing the rims.

It is also possible that elements with an electric drive affect the hubs of the wheels.

It is advisable to implement means for automatic implementation of acceleration and braking processes.

It is better to implement means for automatic implementation of other functional tests.

It can be, for example, a car test for vibration strength or light tests.

It is better to implement means for transporting finished cars in a hanging position from the assembly shop.

At the same time, it is expedient to branch off to the neighboring working area.

Means for hanging transportation of cars from the assembly shop have the advantage that after the final assembly, the cars can be transported from the assembly shop to the storage place while remaining in a hanging position. Due to this, emissions of toxic substances due to the start and departure of cars from the assembly shop are prevented, and at the end of hanging transportation, the orderly automated and controlled placing of finished cars in the parking lot can be carried out. If necessary, within the limits of transportation in the hanging position, branching to the adjacent working area, where deficiencies are eliminated, can also be performed.

Below, the invention is explained with the help of examples of its implementation. The drawings show: - FigLa: a separate module, according to the invention, in cross-section; - Fig. 1p: side view, according to Fig. 1a; - Fig2a: in cross-section, a separate module, according to the invention, in the area of seat manipulation with height adaptation; - Fig. 2r: side view, according to Fig. ha; - Fig. Za: a separate module, according to the invention, in cross-section with adaptation in height and lateral adaptation when manipulating the instrument panel; - Fig. 3p: side view, according to Fig. Za; - Fig. 3c: top view, according to Fig. 3a, 3b; - Fig. 4: device, according to the invention, for assembling aggregates; - Fig. Ba: a top view of the stand for tests on rolling, braking and ABS in the suspension; - Fig. 5p: side view, according to Fig. 5a.

As shown in Fig. 1a, 16, individual modules (modular "working areas") contain a supporting structure of longitudinal 1 and transverse 2 beams, on which transport devices C for the collapsible car and power lines, such as current cables and cables, are located data transmission, pneumatic supply and other devices such as ropes for indicators and rails for trolleys and pneumatic devices. For power lines, in particular for power supply, at the junction of two separate modules, quick-acting connections are made, providing power supply from one separate module to another. Thus, one of the individual modules is made with the possibility of connection to the supply lines in the shop, and through quick-acting connections, other individual modules can be provided together without the need for this complex individual connection of all individual modules. It is also possible to connect individual modules to power lines separately.

Further, individual modules also contain a conveyor belt 4 for workers or, as an alternative, a platform.

It is possible to feed the material from the side in carts 5 or remove it from the racks 6.

Fig. 2a, 25 shows a separate module with a height adapter 7, with the help of which you can reach a height that exceeds the normal design height. This can also be achieved due to extra long supports.

Accordingly, Fig. 3b shows a separate module with a height adapter 7 and a side adapter 8, with the help of which a width exceeding the normal design width can also be achieved.

Figure 4 shows the device according to the invention in the form of individual modules installed in a row for assembling aggregates, and individual sections are marked as sections 1-19.

Fig.Ba, 50 shows a stand for tests on rolling, braking and ABS in the suspension (when transporting the car in a hanging position), and loading units 10 affecting tires, rims or wheel hubs are brought from the side outside to the wheels of the car, and provided means 11 for moving the wheel stand. Next, vibrators 12 are installed under each loading unit 10, which can be used to create a vibrating movement. y y y snu Odiachntnyh poruma ra y pen Ktshi knizhn
