Ultrasonic door panel welding machine

Abstract

The invention relates to equipment for welding automobile door panels, and discloses an ultrasonic door panel welding machine. The ultrasonic door panel welding machine mainly aims to solve the problem that an existing ultrasonic door panel welding machine is low in welding density. The ultrasonic door panel welding machine comprises a machine frame, front-and-back movement control air cylinders, bottom dies, cross beams, up-and-down movement control air cylinders, hanger plates and hanger plate fixing boards. A hanger rod assembly on each hanger plate fixing board comprises a movable vertical board and a fixed vertical board, wherein for each hanger rod assembly, the movable vertical board is connected with a lower transverse board, the fixed vertical board is connected with an upper transverse board which is connected with the hanger plate fixing board, a bolt hole of the movable vertical board and a long hole of the fixed vertical board are connected through a regulating bolt, a guide rod is fixed to the top of an energy converter shield, a limit nut is installed at the portion, extending out of a hole of the lower transverse board, of the guide rod, a spring is installed on the guide rod in a sleeved mode, a guide rail on the energy converter shield is installed in a slide block of the movable vertical board, an energy converter is installed inside the energy converter shield, a locating and compressing pipe is fixed to a guide column, and a compressing head is arranged at the bottom end of the locating compressing pipe which is sleeved with a spring. The ultrasonic door panel welding machine has the advantage of being high in welding density.

Description

Technical field: [0001] The invention relates to a device for welding automobile door panels. Background technique: [0002] The existing ultrasonic door panel welding machine comprises a frame on which several front and rear motion control cylinders and several bottom molds are fixed. The bottom of each bottom mold has a guide rail, and the guide rail is placed in the guide rail seat, which is fixed On the frame, each bottom mold is connected and fixed to the cylinder rod ends of one or two front and rear motion control cylinders, and the front and rear motion control cylinders work to drive the bottom mold to move forward and backward on the frame; It also includes several crossbeams, each of which is fixed on the frame through a column, and several upper and lower motion control cylinders, the cylinder body of each up and down motion control cylinder is fixed on the crossbeam, and each of the upper and lower motion control cylinders The bottom end of the cylinder rod of ...

AI Technical Summary

Problems solved by technology

However, the existing suspender assembly has a complex structure, a large volume, and takes up a lot of space. The number set on a hanging plate fixing plate is small, and the welding density is low. It can only weld about 50 solder joints on a square meter door plate. Poor welding effect, prone to failure, low safety performance
