<p>The present invention relates to a portable large flange machining device and, more specifically, to a portable large flange machining device which is a portable type to machine a large flange in a field and which enables precise machining while reducing setting hours by coupling rotary arms to one side of fixed arms of a fixing part using hinges. In the portable flange machining device according to the present invention, a fixing part (20) comprises: fixed arms (21) radially coupled to a base (10); rotary arms (23) coupled to one side of the fixed arms (21) by hinges (22) and folded in installation and separation; and jack rods (24) coupled to the end of the rotary arms (23) and fixed on the inner circumference of a flange after being transferred by being engaged with a screw. The present invention can reduce transfer costs and hours by machining an object to be machined in a field without transfer by making the device portable, can obtain safety and accuracy by machining the object in a field, and can be easily installed and separated by securing a wide installation space using a structure of folding the rotary arms (23) in the installation and the separation since the hinges (22) are coupled to one side of the fixed arms (21) and the rotary arms (23).</p> |
