Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a movable pressing clamp for welding and fixing. Background Art

[0002] As the ATM market expands, customers are increasingly customizing the appearance and functions of ATMs, which puts higher demands on the production side. How can we better meet customer requirements while improving the process? For example, how to ensure the flatness of sheet metal parts of different sizes after welding? This project studies how to solve the production problem of traditional clamps being difficult to fix when welding sheet metal parts such as top covers and false doors.

[0003] The top cover of the safe is welded from several thin plates. For example, the left plate of the top cover needs to be welded with reinforcing ribs before welding. However, the top cover and false door are large sheet metal parts with unstable dimensions. Therefore, when welding parts, if they are not fixed throughout the process, the thermal deformation caused by welding can easily affect their flatness, resulting in defects and rework. If traditional clamps are used for fixing, the disadvantage is that the height and length of the clamp arm cannot be adjusted. Sometimes the edge of the sheet metal is high and large in size, and the height and length of the traditional clamp arm are not enough to accurately fix the sheet metal. In addition, the angle is fixed and cannot be adjusted freely, which is also inconvenient to use. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a movable pressing clamp for welding fixation, which is easy and flexible to use and can meet the needs of welding and fixation of sheet metal parts of different sizes; the movable pressing clamp is designed with a lifting block to adjust the height of the pressing clamp arm, ensuring that the pressing clamp arm can cross the sheet metal parts with high edges to fix them before welding; the sliding block and the lifting block have strong versatility and can change the fixing length of the pressing clamp arm to meet the needs of welding and fixation of sheet metal parts of different sizes, especially large sizes.
