Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an ultrasonic plastic welder for processing new energy automobile parts. Background Technique

[0002] Automobile parts processing mainly involves multiple technological processes, aiming to produce various components required for automobiles. These processes include stamping, welding, cutting, assembly, surface treatment, and inspection and testing, etc.

[0003] Existing ultrasonic plastic welders for automobile parts processing have some defects during use. For example, the cooling effect of the ultrasonic plastic welder is relatively low after welding, and there is no rotating cylinder provided on the ultrasonic plastic welder, so circular welding cannot be achieved.

[0004] As disclosed in a Chinese patent CN207359660U, an ultrasonic plastic welder for automobile parts processing fixes the automobile parts to be processed on a fixture. Through the KS02Y controller, devices electrically connected to the KS02Y controller all work normally. The ultrasonic generator emits ultrasonic waves, and the transducer receives the acoustic signal and converts the signal into mechanical energy. The hydraulic pump works to extract the hydraulic oil inside the hydraulic oil tank and transports it to the inside of the hydraulic cylinder through the hydraulic oil pipe. The hydraulic cylinder works to drive the telescopic rod to expand and contract. The expansion and contraction of the telescopic rod aligns the welding head with the part to be welded. The welding head conducts to the parts to be processed, causing the two plastic joint surfaces to generate intense friction under the action of ultrasonic waves. The frictional heat melts the plastic joint surfaces to complete gluing. The electric telescopic rod works to extend the fan blade close to the processed parts. The drive motor works to drive the fan blade to rotate, cooling the welded parts. At the same time, the rotating cylinder works to drive the clamping table to rotate by a certain degree, welding the parts on another fixture. After the parts on the welded fixture are cooled, the parts on this fixture are removed, and the required parts are reassembled, then circular welding can be carried out, improving the processing efficiency.
