Abstract

The utility model relates to a steel grating ruggedness test instrument. Including torque spanner and wane, torque spanner have the handle bar, handle bar one end is the handle, the other end is fixed with the torsion square shaft, fixed calibrated scale on the handle bar, fixed pointer on the torsion square shaft, handle bar pass through the torsion square shaft with the wane fixed, be fixed with the fulcrum axle on the wane, couple in addition on the wane, couple, fulcrum axle and torsion square shaft be triangular distribution. Its simple structure, discernment is simple, does not need to calculate, and minimum strength index is mark down to the contrast specification can.

Description

Steel grating ruggedness test instrument

Technical field

This utility model relates to a kind of instruments of inspection, particularly to the ruggedness test instrument of a kind of steel grating.

Background technology

At present, the commonly used resistance welder welding fabrication of production of domestic steel grating, the adjustment of welding current, pressure and other side directly affects the weld strength of twisting square steel. And the weld strength of twisting square steel is checked and does not seek unity of standard, the general method of inspection makes a crowbar, rule of thumb exerts oneself to prize, solder joint do not open be considered as qualified. Completely by virtue of experience, the size differences that different people prizes power is very big for this kind of method, it is impossible to illustrate that the weld strength of twisting square steel is qualified completely.

Summary of the invention

In order to overcome the shortcoming of prior art, this utility model provides a kind of steel grating ruggedness test instrument. Its simple in construction, identifies simple, it is not necessary to calculate, and comparison specification writes down minimum strength index.

The technical scheme in the invention for solving the technical problem is: include torque spanner and seesaw, described torque spanner has handlebar, handlebar one end is handle, the other end is fixed with torsion square shaft, and handlebar is fixed graduated disc, fixed pointers on torsion square shaft, handlebar is fixed by torsion square shaft and described seesaw, seesaw is fixed with fulcrum shaft, seesaw also has hook, described hook, fulcrum shaft and the distribution triangular in shape of torsion square shaft.

This utility model is easy to operate, identifies simple, it is not necessary to calculate, and comparison specification writes down minimum strength index; Coming into operation of this instrument provides guarantee for control of product quality and welding parameter adjustment.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this this utility model is further illustrated.

Fig. 1 is this utility model schematic diagram;

Fig. 2 is that this utility model uses view.

Detailed description of the invention

As shown in Figure 1, 2, this utility model includes torque spanner and seesaw 2, described torque spanner has handlebar 5, and handlebar 5 one end is handle 8, and the other end is fixed with torsion square shaft 3, handlebar 5 is fixed graduated disc 7, fixed pointers 6 on torsion square shaft 3, handlebar 5 is fixed with described seesaw 2 by torsion square shaft 3, and seesaw 2 is fixed with fulcrum shaft 4, seesaw 2 also has hook 1, described hook 1, fulcrum shaft 4 and torsion square shaft 3 distribution triangular in shape.

Described handlebar 5 is detachably fixed by torsion square shaft 3 and described seesaw 2.
