Abstract
The utility model relates to a depth indicator for measuring depth of a blind hole, comprising a measuring head, a scale rod, a guide sleeve and a set screw, and being characterized in that the diameter of the measuring head is matched with the diameter of a reamed hole; the coordinating clearance is 0 to 0.5mm; a little groove is arranged on a cylinder outside the measuring head; a scale marked with a minimum interval of 0.5mm is marked on the scale rod; and the scale rod slides in the guide sleeve. The depth indicator for measuring depth of a blind hole can measure the depth of the reamed holes with different hold diameters by exchanging the measuring head, and solves the problem that the reamed hold cannot be measured because the reamed hold differs too little from the bottom hole diameter.
Description
Technical field the utility model relates to mechanical measurement technique field, particularly pit gauge.
The background technology detection technique is the important means that guarantees mechanical product quality, and the vernier caliper of special pit gauge or band depth survey function is arranged on the market now, and measuring accuracy can reach 0.02 millimeter; Its versatility is more intense; Can measure linear size and diameter dimension, still, when measuring the fraising degree of depth because the diameter of fraising and bottom outlet differs very little; Generally, can't measure with the vernier caliper of pit gauge or band depth survey function also with regard to the 0.1-0.2 millimeter.
The purpose of summary of the invention the utility model provides a kind of measurement blind hole depth and uses pit gauge; This measurement blind hole depth is to propose a solution to the problem that exists in the background technology with pit gauge, has solved the measurement of measurement of articulation blind hole depth and the nonplanar blind hole depth in bottom.
The purpose of the utility model realizes through following technical scheme: a kind of measurement blind hole depth is used pit gauge; Form by gauge head, scale bar, guide pin bushing, fixed clamping screw four parts; It is characterized in that the diameter of gauge head and the diameter of fraising match, tolerance clearance 0-0.05 millimeter is opened a sulculus and is used for exhaust on the gauge head outside cylinder; The scale bar is marked with the scale mark of 0.5 millimeter of minimum interval, and the scale bar slides in guide pin bushing.
This measurement blind hole depth has with the advantage of pit gauge: can measure the fraising degree of depth in different apertures through changing gauge head.Solved fraising because differ too little and problem that can't measure with bottom diameter.
Description of drawings Fig. 1 is the structural representation of the utility model.
Among the figure, scale bar (1), guide pin bushing (2), fixed clamping screw (3), gauge head (4).
Embodiment is described further the utility model below in conjunction with accompanying drawing and embodiment.
Pit gauge in the present embodiment is made up of scale bar (1), guide pin bushing (2), fixed clamping screw (3), gauge head (4) four parts.The diameter of gauge head (4) and the diameter of fraising match, and tolerance clearance 0-0.05 millimeter is opened a sulculus and is used for exhaust on the gauge head outside cylinder.Scale bar (1) is marked with the scale mark of 0.5 millimeter of minimum interval, and scale bar (1) slides in guide pin bushing (2).The upper surface of guide pin bushing (2) is exactly the numerical value shown in that scale mark with the corresponding depth value of which bar scale mark.Fixed clamping screw (3) is tightened, can be taken out reading.During assembling, be through scale bar (1) in the hole of guide pin bushing (2) earlier, then gauge head (4) be screwed on the screw thread of scale bar (1).The small end face of scale bar (1) should closely contact with the end face of gauge head (4) and not interspace.At last fixed clamping screw (3) is screwed to interior the getting final product of threaded hole of guide pin bushing (2).
