AI Technical Summary

Technical Problem

In the existing technology, the spherical mirror stainless steel plate is welded using single-point clamping, which results in the whole plate not being able to fit completely and tightly with the spherical surface of the lower support plate, generating residual welding stress and affecting the welding quality.

Method used

Design a spherical pressing device, including at least two pressing frames and a vertical support rod. The pressing frames are vertically adjustable and connected to the vertical support rod, located on the inner and outer sides of the ring formed by the welding points of the stainless steel plates, respectively. The pressing frame applies a downward force to the vertical support rod through a pressure plate, so that the welding points of the stainless steel plates are completely in contact with the spherical surface of the lower support plate.

Benefits of technology

This design achieves complete fit between the stainless steel plate welding point and the spherical surface of the lower support plate, preventing residual welding stress, ensuring the quality and stability of the welding point, and improving the versatility and adaptability of the device.

Abstract

The utility model relates to the field of frock structure discloses a spherical surface compression device, including at least two compression frames, vertical support pole and pressing plate, the bottom of two compression frames all is provided with the compression ring, the compression frame all can be adjusted to connect on vertical support pole up and down, in the working condition, the compression ring of two compression frames is located in the inside and the outside of the ring of stainless steel plate welding point constitution respectively, and is all pressure joint in the upper end of stainless steel plate, the top of vertical support pole leans against the lower extreme of pressing plate, the utility model has the beneficial effect that, through setting up the pressing plate to the downward force of screw rod is added, so as to be convenient for two compression frames to force the inside and the outside of the ring of stainless steel plate welding point constitution simultaneously, makes stainless steel plate welding point place and lower support plate spherical surface complete adhesion, prevents the welding residual stress of welding place, ensures the quality of welding point.
