Description

Technical Field

[0001] This utility model relates to the technical field of sealing testing mechanisms, specifically a quick-change sealing mechanism. Background Technology

[0002] Existing products require sealing tests after manufacturing, necessitating the use of a sealing mechanism to seal the corresponding ports. However, existing sealing mechanisms require external three-axis moving mechanisms for port alignment, which are relatively bulky, resulting in a large sealing mechanism that lacks quick-change functionality. Furthermore, in practical use, the sealing head lacks automatic small-pitch adjustment, making reliable sealing impossible even with minor errors at the product ports. Utility Model Content

The mounting boss has a guide hole corresponding to the outer periphery of the arc-shaped spherical groove. The guide hole is concave along the thickness direction of the mounting boss. The sealing head includes a back mounting positioning plate, a middle connector assembly structure, and a front-end protruding sealing soft rubber post. The back mounting positioning plate includes a central arc-shaped spherical groove and surrounding guide protrusions. The guide protrusions are inserted into the guide holes and connected by a floating spring. The front end of the centering steel ball is embedded in the central arc-shaped spherical groove. The floating spring holds the sealing head in place. The diameter of the guide protrusions is slightly smaller than that of the guide holes.

[0010] Its further features are:

[0011] The X-axis drive screw assembly includes a first fixed block and an X-axis drive screw. The four corners of the first moving plate are provided with X-direction elongated slots. The first moving plate is connected to the front end of the back plate via fastening bolts and X-direction elongated slots. The first fixed block is fixed to one of the vertical sides of the back plate. The X-direction drive screw passes through the through hole on the first fixed block and is threaded to the corresponding X-direction threaded hole of the first moving plate. This allows the first moving plate to move in the X direction along the back plate through the X-direction elongated slots when the X-axis drive screw rotates.

[0012] The Y-axis drive screw assembly includes a second fixed block and a Y-axis drive screw. The second moving plate has Y-direction elongated slots at its four corners. The second moving plate is connected to the corresponding front end of the first moving plate via fastening bolts and Y-direction elongated slots.
