Description

The working principle and structural layout of the existing corner assembly machine are very mature and are widely used in the door and window processing industry. Figure 7 As shown, this is a common structure of an existing angle assembly machine, including a workbench, on which an outer angle positioning mechanism and an inner angle positioning mechanism are longitudinally spaced, and two punching and riveting mechanisms are symmetrically arranged laterally. The inner angle positioning and punching and riveting actions are all completed by oil cylinders.

[0003] Although the existing corner assembly machines can also complete the corner assembly action, there are still many technical problems that deserve in-depth research and solution in practical applications. For example, although the use of oil cylinder drive has the advantage of sufficient power, the oil system has high cost, cumbersome maintenance and pressure control, and easy pollution. In addition, when the drive stroke needs to be adjusted, it is usually necessary to manually adjust the limit structure to achieve it. Overall, the maintenance cost is high and the operation control is cumbersome. Although there are also technical solutions that use air cylinders instead of oil cylinders, such as the pneumatic corner assembly machine for aluminum doors and windows disclosed in the Chinese patent, authorization announcement number CN215787997U, and some positive effects have been achieved, there are still cumbersome adjustment operations and technical problems such as internal positioning retreat when impacted by punching and riveting movements, which in turn affects the quality of corner assembly. Therefore, it is necessary to improve and optimize the structure of the existing corner assembly machine in order to improve the efficiency and quality of corner assembly.
