The invention provides a crimping type power module valve segment and a valve segment frame. The crimping type power module valve segment comprises the valve segment frame and a plurality of power modules which are arranged on the valve segment frame in a compressed and clamped manner, wherein the valve segment frame comprises a left end plate and a right end plate, the two end plates are each provided with a top pressing part in top pressing fit with the power modules, through holes distributed at intervals along the fore-and-aft direction are formed in the two end plates, the through holes are used for mounting corresponding ends of front insulating pull rods and rear insulating pull rods in a cooperative manner, the two ends plates are fixed together by means of the front insulating pull rods and the rear insulating pull rods which extend along the fore-and-aft direction, one of the two end plates is a curve-surface pressure-bearing end plate, and a stress balance indicator which isused for indicating that the end plate is balanced under acting forces of the front and rear insulating pull rods is fixedly arranged on the curve-surface pressure-bearing end plate. The crimping type power module valve segment utilizes the stress balance indicator to observe a flat-straight state of the upper curve surface of the curve-surface pressure-bearing end plate, ensures that two end surfaces of the valve segment are completely parallel and are perpendicular to an axial direction of the insulating pull rods, and avoids the overall inclination of the valve segment.
