Description

Technical Field

[0001] This utility model relates to the field of automobile production and assembly, specifically to a chassis assembly fixture suitable for trucks and monocoque bodies. Background Technology

[0002] With increasingly diverse product demands, car manufacturers need to produce a wider variety of products. Currently, car manufacturers produce fewer product types because the manufacturing processes for trucks and monocoque chassis differ significantly. Trucks are assembled with the chassis first, then the cab is joined. During truck chassis assembly, the chassis height is typically 800-900mm. Monocoque chassis, on the other hand, place the body at a higher position, requiring workers to stand below for assembly. The final assembly line struggles to accommodate the chassis assembly of both trucks and monocoque chassis.

[0003] At present, a tooling suitable for assembling trucks and monocoque chassis is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling suitable for assembling truck and monocoque chassis to solve the problem that the current assembly line is difficult to be compatible with the chassis assembly of trucks and monocoque bodies because the body is placed in a high position and people stand below to assemble it.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A chassis assembly fixture suitable for trucks and monocoque bodies includes an upper fixture and a lower fixture. The upper fixture includes an upper frame and a pin assembly. The upper frame supports the monocoque body. The lower fixture includes a chassis and a support frame. The support frame is mounted on the chassis and has pin holes that match the pin assembly. The pin assembly is mounted below the upper frame. The upper fixture is detachably mounted on the lower fixture via the pin assembly and pin holes. There are two lower fixtures, respectively located directly below the left and right sides of the upper fixture.

[0007] Further specifying, the chassis is provided with four traveling wheels for traveling on the track, which are respectively installed at the four corners of the chassis. The chassis is also provided with fixing pins, which connect the chassis to the bottom conveyor drag chain, and the bottom conveyor drag chain drives the lower tooling to travel on the track.

[0008] Furthermore, the upper tooling also includes a front pin assembly and a rear support assembly. The size of the upper frame is larger than the size of the load-bearing vehicle body. The front pin assembly and the rear support assembly are both installed on the inner sidewalls of the front and rear sides of the upper frame.

[0009] Further specifying, the pin assembly includes four pins, which are respectively disposed on the lower left and right sides of the upper frame, with two pins on each side.

[0010] Further specifying, the rear support assembly includes a fixed placement plate and a movable placement plate, a fixed plate is provided on the inner side of the front frame of the upper frame, a slide rail is provided on the fixed plate, a slider is provided on the slide rail, and the movable placement plate is mounted on the slider.

[0011] The advantages of this utility model over the current technology are as follows:

[0012] The lower tooling is equipped with fixed pins and traveling wheels. The lower tooling is driven on the track by the bottom conveyor drag chain. It can be used for truck chassis frames of different lengths. When generating a monocoque body, the lower tooling and the upper tooling can be used together. They can be switched at any time, which is convenient and quick. It also solves the problem that the current final assembly line is difficult to be compatible with the chassis assembly of trucks and monocoque bodies. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0021] like Figures 1-6 As shown, a chassis assembly fixture suitable for trucks and monocoque bodies includes an upper fixture 1 and a lower fixture 2. The upper fixture 1 includes an upper frame 11 and a pin assembly. The pin assembly includes four pins 12, which are respectively arranged on the lower left and right sides of the upper frame 11, with two pins 12 on each side. The upper frame 11 is larger than the size of the monocoque body 3 and is used to support the monocoque body 3. The lower fixture 2 includes a chassis 21 and a support frame 22. The support frame 22 is mounted on the chassis 21 and has pin holes that match the pin assembly. The upper fixture is detachably mounted on the lower fixture 2 through the pins 12 and the pin holes.

[0022] The chassis 21 is equipped with four traveling wheels 4 for traveling on the track. The four traveling wheels 4 are installed at the four corners of the chassis 21. The chassis 21 is also equipped with fixing pins 23, which connect the chassis 21 to the bottom conveyor drag chain. The bottom conveyor drag chain drives the lower tooling 2 to travel on the track. There are two lower tooling 2. When it needs to be used in conjunction with the upper tooling 1, the lower tooling 2 is driven by the bottom conveyor drag chain to travel on the track and move to the left and right sides directly below the upper tooling 1 for assembly.

[0023] The upper fixture 1 includes a front pin assembly 5 and a rear support assembly. Both the front pin assembly 5 and the rear support assembly are installed on the inner sidewalls of the front and rear sides of the upper frame 11. The rear support assembly includes a fixed placement plate 6 and a movable placement plate 7. A fixed plate 8 is provided on the inner side of the front frame of the upper frame 11. A slide rail 9 is provided on the fixed plate 8. A slider 10 is provided on the slide rail 9. The movable placement plate 7 is installed on the slider 10.

[0024] When producing a truck chassis, only two lower fixtures 2 are used to support the truck chassis frame. The chassis frame is then placed on the two lower fixtures 2, and the distance between the two lower fixtures 2 is adjusted according to the length of the chassis frame. Workers assemble the truck chassis components. When producing a monocoque body, the two lower fixtures 2 are moved to the left and right sides directly below the upper fixture 1. They are combined with the upper fixture 1 through the cooperation of four pins 12 and pin holes. The upper fixture 1 is located on the two lower fixtures 2. The monocoque body 3 is placed on the upper fixture 1, and workers assemble the monocoque body 3. The fixed placement plate 6 and the movable placement plate 7 provide support. The movable placement plate 7 can adjust the support position of the monocoque body 3.
