Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a welding device for upper and lower shells of an intake manifold. Background Art

[0002] The intake manifold refers to the intake pipeline from the carburetor or throttle body to the cylinder head intake passage. Its function is to distribute the air and fuel mixture from the carburetor or throttle body to the intake passages of each cylinder. For an airway fuel injection engine or a diesel engine, the intake manifold only distributes clean air to the intake passages of each cylinder. The intake manifold must distribute the air, fuel mixture or clean air to each cylinder as evenly as possible. For this reason, the length of the gas flow passage in the intake manifold should be as equal as possible. In order to reduce the gas flow resistance and improve the intake capacity, the inner wall of the intake manifold should be smooth. Traditional engine intake manifolds are basically manufactured by vibration friction welding technology. This technology solves the limitations of ordinary injection molds. The upper shell and the lower shell of the intake manifold are welded into one body to form a tubular part with a hollow air passage inside. For example, an intake manifold welding tool with an integrated error-proofing function and publication number CN219336366U includes a welding tool body and an intake manifold. The welding tool body includes an upper template, the bottom of the upper template An upper mold block is fixedly connected by bolts, a lower mold block is arranged at the bottom of the upper mold plate, a lower mold block is fixedly connected to the top of the lower mold plate by bolts, a laser sensor assembly is fixedly connected to the top of one side of the lower mold plate, the intake manifold includes an upper plate, a lower plate is arranged at the bottom of the upper plate, a guide plate is arranged inside one side of the lower plate, four corners of the bottom of the upper mold plate are fixedly connected to guide seats, and four corners of the top of the lower mold plate are fixedly connected to guide columns; the technical points are: by installing a laser sensor assembly on the top of one side of the lower mold plate, the laser sensor assembly directly detects the guide plate inside one side of the lower mold plate, and in the process of using vibration friction welding of the upper and lower mold plates, it can be 100% detected whether there is a guide plate inside one side of the lower mold plate; wherein the lower mold plate is fixedly installed on the working table of the vibration friction welding machine by multiple bolts during installation, which is troublesome to install, and the upper mold plate is installed on the vibration head, which requires the staff to hold it with both hands, and then another staff member fixes it by bolts, which is labor-intensive.
