摘要： Present invention provides a universal fixture that fits a broad range of flange/pipe sizes, covering the common sized 4-hole to 24-hole flanges. The present invention solves the end play issue (between the mounting studs and the screw holes of the flange) by aligning the centers of the flange to the center of the pipe, relying on the center hole of the OH plate. An additional accessory can be used to set adjustable height support, for propping up pipes and balance the weight, facilitating the ease of handling the welding work.

摘要： The present invention provides an improved release mechanism for clamping tools where problems of thread slipping due to worn out thread can be reduced by the structure of a plunger with a small diameter section and the engagement of the thread shaft is made more secure by the cam action on account of the shape of the plunger. A protrusion extends from a push button on a top portion of the half-threaded nut. Threads are formed on an upper portion of the hole for engaging the threaded shaft. The middle portion of the plunger is made to have a section of small diameter allowing the protrusion to be pushed downward in a normal position and allowing the protrusion to rely on the resilient power of the helical spring to push it upward into the small diameter section.

摘要： Present invention provides a universal fixture that fits a much broader range of flange/pipe sizes, covering the common sized 4-hole to 24-hole flanges, so that the welding to be performed at a job site is made easier due to the flexibility of the fixture introduced herein. The present invention solves the end play issue (between the mounting studs and the screw holes of the flange) by aligning the centers of the flange to the center of the pipe, relying on the center hole of the OH plate. An additional accessory can be used to set adjustable height support, for propping up pipes and balance the weight, facilitating the ease of handling the welding work.
