Technical Field

[0001] The utility model relates to the technical field of automobile tooling, in particular to an automobile welding fixture tooling which can steadily correct a vehicle body. Background Art

[0002] The body refers to the part of the vehicle used to carry people and cargo, and also refers to the vehicle as a whole. The body of some vehicles is both the driver's workplace and a place to accommodate passengers and cargo. The body includes windows, doors, cockpit, passenger compartment, engine compartment and luggage compartment, etc. The body shapes include box type, fish type, boat type, streamlined and wedge type. The structural forms are divided into single compartment, two compartment and three compartment types. The body shape structure is the body language of the vehicle, and its design will directly affect the performance of the vehicle.

[0003] For example, a Chinese patent (publication number: CN213497374U) discloses an automobile tooling fixture for welding automobile parts, including a bracket body and a support member, wherein the support member is movably mounted on the bracket body, and the spacing between the two support members can be adjusted, and also includes: a telescopic member partially inserted into the accommodating cavity in the support member, and the telescopic member can be telescoped along the vertical height; a clamping member, wherein the clamping member is fixed away from one end of the telescopic member away from the support member, and the clamping member is arranged in a direction perpendicular to the telescopic member. By moving the support member in the horizontal direction and the telescopic member installed on the support member in the vertical direction, the position of the clamping member fixed on the telescopic member can be adjusted, so that it can be suitable for clamping automobile parts of different sizes and different positions of automobile parts, effectively improving the practicality of the automobile tooling fixture.

[0032] The working principle of the above embodiment is:

[0033] (1) When the vehicle body needs to be fixed, the vehicle body is placed between the two clamping plates 408, and the electric push rod 401 is started. The electric push rod 401 drives the first rack 402 to move. When the first rack 402 moves, it drives the gear 404 and the first rotating rod 403 to rotate together. The gear 404 drives the second rack 405 to move in the opposite direction of the first rack 402. The first rack 402 and the second rack 405 move in the opposite direction at the same time, driving the two fixing blocks 406 to move relative to each other at the same time. The fixing block 406 drives the clamping plate 408 to move together through the connecting block 407. The vehicle body is stably fixed by the clamping plate 408, which is simple to operate and has a good fixing effect.

[0034] (2) When welding is required, the motor 202 is started, and the motor 202 drives the second rotating rod 203 to rotate. The second rotating rod 203 drives the two first sprockets to rotate together. The first sprocket at the left end drives the second sprocket at the rear end to rotate through the first chain, and the first sprocket at the right end drives the second sprocket at the front end to rotate through the second chain. The second sprocket drives the screw rod 205 to rotate together. Since the two sections of the screw rod 205 have opposite thread directions, the screw rod 205 rotates to drive the two movable blocks 206 to move relative to each other at the same time. The movable block 206 drives the box body 3 to move together through the connecting rod 207. The two box bodies 3 move relative to each other at the same time, which is convenient for driving the two car bodies to move relative to each other, and is conducive to welding the two car bodies.
