When the device is used specifically, a user needs to select and adjust the distance measuring contact 53 according to the profile of the surface to be measured of the die, when the surface to be measured is a straight inclined surface, the distance measuring contact 53 is rotated to a uniform horizontal height, when the surface to be measured is a vertical revolution surface, the distance measuring contact 53 is rotated to be longitudinally distributed, and when the surface to be measured is in other shapes, the distance measuring contacts 53 with different specifications can be replaced according to the requirements for matching use;
after the corresponding distance measuring contact 53 is selected and adjusted, before measurement, the transparent main shell 29 needs to be adjusted to a position perpendicular to the surface to be measured through the mechanical adjusting arm 28, the distance from the edge of the transparent main shell 29 to the impact target position is a constant distance, the distance can be rapidly measured through the contact of the two groups of distance measuring contacts 53 with the surface to be measured, and when the curved surface to be measured is special, the traditional distance measuring mode needs to be adopted;
after the transparent main shell 29 is adjusted, the electromagnet body 21 and the magnetic one-way limiting lantern ring 14 are powered and the adjusting motor 30 is started, the adjusting motor 30 drives the driving special-shaped nut 42 and the driven synchronous wheel 43 to rotate through the driving synchronous wheel 31 and the synchronous toothed belt 32, the adjustment stud 22 is drawn outwardly by the threaded drive between the drive contour nut 42 and the adjustment stud 22, since the electromagnet body 21 and the adsorption armature 9 are adsorbed together at this time, when the sliding adjusting seat 20 slides along the adjusting stud 22, can drive the adsorption armature 9 and the main body impact shaft 8 to slide together, the main body impact shaft 8 drives the sliding guide block 10 to slide and compress the energy storage spring 11 to store elastic potential energy, in the process, the magnetic lantern ring limit valve 19 is attached to the surface of the magnetic one-way limit lantern ring 14 in an adsorption mode, so that the magnetic one-way limit lantern ring can smoothly pass through the circular hole 18 of the number indicating plate;
after the adjusting stud 22 is drawn out to a specified distance, the power supply of the electromagnet body 21 and the magnetic type one-way limiting lantern ring 14 is cut off at the same time, the magnetic lantern ring limiting valve 19 automatically disperses after losing the adsorption force, and the adsorption armature 9 and the main body impact shaft 8 rebound and impact the surface of the die material under the elastic force action of the energy storage spring 11;
after the impact, the main body impact shaft 8 rebounds to a certain extent, due to the limitation of the inclined direction of the magnetic collar limiting petal 19, the main body impact shaft 8 pushes the movable index plate 13 to slide for a certain distance through the magnetic collar limiting petal 19 when rebounding, and as the movable index plate 13 slides and needs to overcome the elastic force of the reset elastic sheet 45 to press the ratchet plate 44 downwards, the sliding extent of the movable index plate 13 is the same as the rebounding extent of the main body impact shaft 8;
the rebound amplitude of the main impact shaft 8 can be judged by observing the final stop position of the movable indicator plate 13 through the transparent main shell 29, and the surface hardness grade of the material to be detected can be further known;
after the reading is finished, the manual retraction handle 46 is manually stretched outwards, and then the transparent main shell 29 is inclined through the mechanical adjusting arm 28, so that the movable display board 13 can be reset in a sliding mode.
The above is the overall working process of the invention, and the steps are repeated when the device is used next time.
