Example Embodiment

[0047] The present invention will be further described below in conjunction with the drawings and embodiments:

[0048] The portable impactor for injury prefabrication in this embodiment includes a gear mechanism, a locking and releasing mechanism, a cylinder mechanism, a rack and pinion guide mechanism, a self-locking trigger mechanism, a trigger locking mechanism, and an energy fine-tuning mechanism. among them:

[0049] Such as figure 1 with figure 2 As shown, the front end of the portable impactor for damage prefabrication of the present invention is the shock-absorbing and limiting mechanism 1. The shock-absorbing and limiting mechanism 1 is connected to the front end of the front end self-locking mechanism 2 and is aligned with the front end of the front end self-locking mechanism 2 with screws. fixed. The rear end of the front end self-locking mechanism 2 is screwed to the front end of the cylinder mechanism 5. The gear mechanism 3, the display and calculation mechanism 8...

Abstract

The invention relates to the field of engineering material structure damage pre-formation, and in particular relates to a portable impactor for damage pre-formation. A shock absorption limiting mechanism is arranged at the frontmost end of the portable impactor, is butted to the front end of a front-end self-locking mechanism and is fixed together with the front end of the front-end self-locking mechanism; the rear end of the front-end self-locking mechanism is in threaded connection with the front end of a barrel body mechanism; a gear mechanism and a display and calculation mechanism are welded at corresponding positions on the outer surface of the barrel body mechanism; a spring and a fine adjustment mechanism are arranged inside a barrel body of the barrel body mechanism and are fixed through rear-end nuts of the barrel body mechanism; a locking and unlocking mechanism is positioned on the outer wall of the barrel body mechanism through a clamping slot and is fixed through a screw. The portable impactor for damage pre-formation is safe, portable, simple, high in environment adaptability and easy to operate; the technical limitations that the conventional impacting device cannot adapt to non-horizontal plane and specially-shaped plane impact or facilitates real-time impacting on the spot due to multiple sets of rear end equipment are well solved.

Description

technical field [0001] The invention relates to the field of damage prefabrication of engineering material structures, in particular to a portable impactor and an impact method for damage prefabrication. Background technique [0002] The structural damage prefabrication of engineering materials has been widely used in the material strength test and research. Among the different damage prefabrication methods, the impact damage prefabrication is more widely used. Impact damage prefabrication is generally divided into: gravity type, spring energy type, pneumatic type, electromagnetic power type and fire control power type, and the most widely used is gravity type. The gravity impact device achieves energy regulation by changing the mass and height of the falling hammer. It has simple structure, accurate measurement, convenience and safety. It is suitable for static level or material impact in the ideal state of the laboratory. Or the special-shaped surface of other large workp...
