Description

Bus roof frame welding tooling

technical field

The utility model relates to a welding tool, in particular to a fixed frame welding tool for a passenger car.

Background technique

The bus roof is an important part of the whole bus. The bus roof includes a roof frame and a roof skin covering the roof frame. The roof frame is welded with criss-cross channel steel. In order to improve the welding efficiency and forming precision of the roof frame, it is very necessary to develop a welding method for the passenger car roof frame.

Utility model content

The purpose of this utility model is to provide a welding tool for the roof frame of a passenger car. The cross beam of the passenger car is placed on the cross beam support, the two ends are positioned, the middle part is locked by a U-shaped slot and claws, and then the longitudinal beam of the passenger car is placed on the longitudinal beam frame. On the top, the positioning block of the longitudinal beam keeps its position unchanged, and then the welding process of the bus roof frame can be carried out.

The technical scheme that the utility model adopts is:

The welding tool for the roof frame of a passenger car, including a base, is characterized in that several groups of beam supports arranged in parallel and corresponding to the beams to be supported in the roof frame are arranged on the base, and each set of beam supports has four And it is arranged in the middle of the beam and at both ends of the beam along the length direction of the beam. The tops of the two beam supports in the middle of each set of beam supports are provided with U-shaped slots and claws. The top of the two beam supports located on both sides is provided with a beam end positioning block, and several longitudinal beam supports corresponding to the longitudinal beams to be supported in the top frame are also arranged on the base, and the longitudinal beam supports It is located between adjacent two sets of beam supports, and a longitudinal beam frame is arranged on the longitudinal beam supports, and several longitudinal beam positioning blocks are arranged on the longitudinal beam supports.

Further, the top of the longitudinal beam support is provided with a first air cylinder, and the longitudinal beam frame is connected with the piston rod of the first air cylinder, and the first air cylinder is connected with the first controller.

Further, the claw is hingedly connected to the beam support, and the bottom of the claw is connected to the piston rod of the second cylinder, and the second cylinder drives the claw and the U-shaped groove to maintain a clamped state or to open state, the second cylinder is connected with the second controller.

The beneficial effects of the utility model are:

The utility model has a simple structure. The passenger car beam is placed on the beam support, and the two ends are positioned. The middle part is locked by a U-shaped slot and claws. The position remains unchanged, and then the welding process of the bus roof frame can be carried out, which is convenient and quick, and the processing precision is high, and is suitable for mass production of the bus roof frame welding process.

detailed description

In order to make the purpose of the utility model and the advantages of the technical solution clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and examples.

As shown in accompanying drawings 1 to 5, the welding tooling for the roof frame of a passenger car includes a base 1, and is characterized in that: on the base 1, there are several groups of beams arranged in parallel and corresponding to the beams that need to be supported in the roof frame There are four supports 2 in each group of beam supports 2 and they are arranged in the middle of the beam and at both ends of the beam along the length direction of the beam. There are U-shaped card slots 3 and claws 4, and the tops of the two beam supports 2 located on both sides of each set of beam supports 2 are provided with beam end positioning blocks 5, and several The longitudinal beam support 6 corresponding to the longitudinal beam that needs to be supported in the roof frame and the longitudinal beam support 6 is located between the adjacent two groups of beam supports 2, and the longitudinal beam support 6 is provided with a longitudinal beam frame 7, Several longitudinal beam positioning blocks 8 are arranged on the longitudinal beam frame 7 .

Further, the top of the longitudinal beam support 6 is provided with a first cylinder 9 and the longitudinal beam frame 7 is connected to the piston rod of the first cylinder 9, and the first cylinder 9 is connected with the first controller to adjust the height of the longitudinal beam .

Further, the claw 4 is hingedly connected to the beam support 2, and the bottom of the claw 4 is connected to the piston rod of the second cylinder 10, and the second cylinder 10 drives the gap between the claw 4 and the U-shaped groove 3. Keep the clamped state or the open state, and the second cylinder 10 is connected with the second controller to improve the degree of automatic operation.

When the utility model is in use, the passenger car beam will be placed on the beam support 2, the beam end positioning block 5 will position the two ends of the beam, the middle part of the bus beam will be locked by the U-shaped card groove 3 and the claw 4, and then the passenger car longitudinal beam will be placed On the longitudinal beam frame 7, the position of the longitudinal beam of the passenger car is kept constant by the longitudinal beam positioning block 8, and then the welding process of the roof frame of the passenger car can be carried out.
