Problems solved by technology
In this application, the rivet welding machine cooperates with the AC servo motor and the screw lifter to drive the hot riveting tooling assembly up and down. There are many hot riveting tooling components of the spot welding machine, and the weight is too heavy, which will cause a huge impact on the structure of the screw lifter, especially the joint between the screw and the threaded pipe in the screw lifter, reducing the structural strength and service life.

Abstract
The invention discloses a multipoint hot riveting welding machine. The multipoint hot riveting welding machine comprises a hot riveting tool, a first driving mechanism and a gravity compensation mechanism. The hot riveting tool comprises a plurality of hot riveting welding heads, the first driving mechanism is used for driving the hot riveting tool to ascend and descend between a first position and a second position, and the gravity compensation mechanism is connected with the hot riveting tool and at least partially compensates for the gravity of the hot riveting tool. The gravity of the hotriveting tool can be balanced through the gravity compensation mechanism, zero self gravity is achieved during ascending and descending, the load of the driving mechanism is reduced, the service lifeof the driving mechanism can be effectively prolonged on the premise of guaranteeing the machining precision, and energy consumption is reduced.
Description
technical field [0001] The application belongs to the technical field of welding equipment, and in particular relates to a multi-point hot riveting welding machine. Background technique [0002] Cars are an important means of transportation. With the rapid development of the automobile industry and the significant increase in the number of cars per capita, people have higher and higher requirements for the quality of cars. Car manufacturers are also constantly improving and innovating in manufacturing processes. , but there are still deficiencies. For example, manual hand-held welding torches are used for welding in the manufacture of automobile door panels. , The inspection process is long, the quality is unstable, and a waste of manpower and material resources. In order to improve work efficiency and output, multi-point welding technology has emerged as the times require, which can perform multi-point welding on workpieces to be welded at the same time.
