Fig. 2 is the structural representation of sleeve.
Fig. 3 is the backplan of Fig. 2.
Fig. 4 is the partial side view of Fig. 2.
In whole accompanying drawings, the gauge head of the retaining sleeve of the dial plate of 1 dial gauge, 2 dial gauges (being also referred to as the bar cover), 3 sleeves, 4 gib screws, 5 dial gauges, the measuring staff of 6 dial gauges.
Embodiment
In Fig. 1 as can be seen, it all is cylindrical that the outer shape of the cavity shape of sleeve 3 and the retaining sleeve of dial gauge 2 is coincide mutually, and the interior body diameter of sleeve 3 is than big 0.1 millimeter of diameter of the outside cylinder of retaining sleeve 2, like this sleeve 3 can be sleeved on the retaining sleeve 2 of dial gauge and with latter's essentially concentric.In Fig. 1, sleeve 3 is fixed on the retaining sleeve 2 of dial gauge by gib screw 4.
This instrument should return to zero earlier before reality is used, adjusting zero method is: earlier with this instrument with hand on the bright and clean hard surface of the coating that the same geometry same curvature is arranged on the surface of the porcelain insulator of coating or with it (it is surperficial to abbreviate zeroing as), the measuring staff 6 of dial gauge is with this Surface Vertical and point to this surface, can shrink automatically after the gauge head 5 of dial gauge contacts with zeroing is surperficial and retreat, so the top of the crown top of sleeve 3 and the gauge head 5 of dial gauge all therewith the surface contact, it is zero that the dial plate 1 that keeps this state and adjust dial gauge makes reading.
The using method of this instrument is: this instrument after will returning to zero with hand is pressed to tested coating, and measuring staff 6 is vertical with tested coating surface and point to tested coating.This moment, the top of gauge head 5 contacted with tested coating surface, the crown of sleeve 3 pierces through tested coating and is against on the surface of coated article (porcelain insulator) under pressure, have displacement between the crown top of sleeve 3 and the top of dial gauge gauge head 5, this displacement equals the thickness of tested coating just and is shown by the dial plate reading.
As long as zeroing surface has the identical curvature of identical geometric configuration with measured surface, this instrument is applicable to the measurement of the solid cladding thickness that more easily pierces through on the hard solid surface of any geometric configuration.The concave curvatures coating less to radius-of-curvature, the top of gauge head 5 of should be before zeroing adjusting (amplifications) dial gauge earlier is than the overhang (unscrewing gib screw 4 can adjust) on the top of the crown of sleeve 3, so that return to zero smoothly.
Below introduce various embodiment of the present utility model.
Principle of the present utility model is around the gauge head at dial gauge several sharp-pointed hard sharp things to be set, and the dial plate of these sharp things and dial gauge fixes or the dial plate by retaining sleeve and dial gauge fixes the tip of sharp thing and the same sensing of the measuring staff of dial gauge.Pressure with hand during use acts on the dial plate, and sharp thing can pierce through that coating is against on the coated article and the gauge head of dial gauge is against on the coating surface, thereby shows the thickness of coating on dial plate.
