Sedan quarter window ultrasonic hot riveting and welding integrated machine

Abstract

The invention provides a sedan quarter window ultrasonic hot riveting and welding integrated machine which comprises a frame. The machine is characterized in that the frame comprises a left sedan quarter window welding unit framework, a right sedan quarter window welding unit framework, work piece base membrane platforms for welding sedan quarter windows arranged in all the sedan quarter window welding unit frameworks, work piece base membrane platform adjusting mechanisms connected with the work piece base membrane platforms, a work piece holding-down device, an ultrasonic welding position provided with a plurality of welding heads, a multi-position hot riveting and welding mechanism and a lifting and guiding synchronizing mechanism; a PLC (Programmable Logic Controller) control platform controlled by gas and electric circuits is also connected with the side surface of the frame; and a work piece cold blowing pipe is also arranged on the work piece holding-down device. The machine has the beneficial effects that as two welding heads are adopted for simultaneous welding, depths of the welding heads can be accurately controlled, and 250*150mm special-shaped curved surface objects can be welded. A welded sedan quarter window has high water seal performance and bright appearance, and work pieces are not damaged after being painted.

Description

technical field [0001] The invention relates to an integrated ultrasonic heat riveting welding machine for triangular windows of cars. Background technique [0002] At present, the use of ultrasonic welding technology for triangular windows of domestic cars is known, but there is no relevant literature report on the welding equipment that is compatible with ultrasonic welding and hot riveting. And general car triangular window transport ultrasonic welding technology equipment exists: the car triangular window water-tight performance after welding is poor, the brightness of appearance is not high, easy to damage after painting. Colleagues' existing ultrasonic welding equipment uses single welding head welding, and the welding depth of the welding head is difficult to control. However, the existing triangular window welding equipment for cars adopts the force in the positive direction, so the welding precision is not high; the workpiece is easily deformed after welding. Con...

Problems solved by technology

[0002] At present, the use of ultrasonic welding technology for the triangular window of domestic cars has been known, but the welding equipment compatible with ultrasonic welding and hot riveting has not been reported in relevant literature

However, the general ultrasonic welding equipment for triangular windows of cars has the following problems: the watertightness of the triangular windows of cars after welding is poor, the brightness of the appearance is not high, and it is easy to be damaged after painting.

Colleagues' existing ultrasonic welding equipment uses single welding head welding, and the welding depth of the welding head is difficult to control

However, the existing triangular window welding equipment for cars adopts the force in the positive direction, so the welding accuracy is not high; the workpiece is easily deformed after welding
