The utility model adopts technique scheme, digging teeth height measurement device comprises the measurer that has flexible gauge head and can detect the telescopic displacement of flexible gauge head, also comprise the measurer bearing being placed on measured tooth head matrix around for supporting, described measurer bearing is provided with for fixing described measurer and makes the flexible direction of its gauge head along the measurer fixed sturcture of the tooth depth direction setting of tooth head, the bottom of described measurer bearing is provided with the open space entering for the tooth head of drill bit, the gauge head of described measurer overhangs in described open space, therefore, when use, measurer bearing is supported on measured tooth head matrix around, make tooth head enter in open space and top pressure stretch contracting gauge head, the telescopic displacement of the flexible gauge head that can detect by measurer and tooth the head not telescopic displacement before top pressure stretch contracting gauge head are determined the height of tooth head, realize the direct measurement to drill bit tooth depth, easy to operate, fast, can effectively ensure the quality of product, enhance productivity.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model digging teeth height measurement device;
Fig. 2 is the use view of digging teeth height measurement device in Fig. 1.
The name that in figure, each Reference numeral is corresponding is called: 10 dial gauges, 11 gauge outfits, 12 sleeves, 13 flexible gauge heads, 20 measuring cylinders, 30 holding screws, 40 drill bits, 41 tooth heads.
Embodiment
An embodiment of the utility model digging teeth height measurement device, as shown in Fig. 1 ~ Fig. 2, is a kind of specific purpose tool for digging teeth high measurement, comprises dial gauge 10 and measuring cylinder 20, and dial gauge 10 is as measurer, and measuring cylinder 20 is as measurer bearing.
Dial gauge 10 is prior art, comprises gauge outfit 11, flexible gauge head 13 and the sleeve 12 for flexible gauge head 13 guiding movements assemblings, and gauge outfit 11 can detect the telescopic displacement of flexible gauge head 13, and the numerical value that telescopic displacement is converted into quantification is shown.Measuring cylinder 20 is sleeve-shaped, for stable support to measured tooth head 41 matrix around.The bottom opening of measuring cylinder 20, forms the open space entering for the tooth head 41 on drill bit 40, and top is provided with capping, is provided with the jack inserting for the sleeve 12 of dial gauge 10 in capping in central axis place.On the sidewall of measuring cylinder 20, be also provided with threaded hole and be installed with holding screw 30, holding screw 30 is along the radially setting of measuring cylinder 20, and front end is the top pressure side for hold out against respectively and discharge described measurer in the time screwing and unscrew, and can realize fixing dial gauge 10.In addition, after holding screw 30 unscrews, can also make dial gauge 10 relatively move up and down with measuring cylinder 20, thereby the position of the flexible gauge head 13 of adjustment dial gauge 10 in measuring cylinder 20 is convenient for measuring.
