Abstract
The utility model relates to a digital micro depthometer with a dial gauge, which is the generation-changing product of a vernier depthometer and is a micro measuring instrument for measuring the depth of a blind hole, the depth of a circular bead in the hole and the depth of circular beads of various structures. The digital micro depthometer is composed of a main ruler (3), a slidable micro measuring bar (1) in the central groove of the main ruler, and a meter head installed on the ruler body of the main ruler. The depth dimensions is displayed out with the millimeter grade numerical values on the micro measuring bar and lower than millimeter grade numerical values on the meter head by that a gear in the meter head is engaged with a rack gear on the micro measuring bar. The instrument has the advantages of visual and accurate read number, little visual error and convenient operation.
Description
The utility model belongs to surveying instrument, is a kind of accurate measurement pit gauge that is used to measure the shoulder degree of depth in blind hole depth, the hole.
For the measurement of the shoulder degree of depth in blind hole depth, the hole and the various member shoulder degree of depth, using maximum at present is slide calliper rule or depth vernier gage.Major defect is, reading is not directly perceived, and the collimation error is big.In addition, (number of patent application: 93232863.6), also directly reading fathoms the two shockproof slide calliper rule dial gauges of numeral pointer-type of the applicant's application.But because measurement function many (mainly measuring the inside and outside size of part), so structure is complicated, uses also not very convenient.
The purpose of this utility model is to provide a kind of simple in structure, the band table accurate measurement pit gauge that reading is intuitively accurate, easy to use, cheap.
The technical solution of the utility model is, on main scale (3), be provided with measuring basis and the initial groove of millimeter level, there is sliding tray at middle part at main scale (3), adorning the accurate measurement bar (1) that can in groove, slide in the groove, stud with accurate measurement tooth bar (13) on the accurate measurement bar, on the blade of main scale (3), gauge outfit (2) also is housed, be contained in the stud wheel of garden up and down (6 in the clamping plate (8) in tooth bar on the accurate measurement bar (13) and the gauge outfit (2), 7) engagement, the garden stud wheel (6 up and down, 7) the in-line gears sheet (12) on drives needle pivot (11), pointer (5) rotates on dial plate, thereby tested depth dimensions is indicated on dial plate, the displacement of the lines on the accurate measurement bar (1) is passed through tooth bar, gear rotation becomes the angular displacement of pointer.The enlargement factor of transition process is K, K=(2 π L)/2=(2 π * 15.9)/2=50, and like this, depth dimensions 0.02mm shows on the dial plate, just amplifies the reading lattice of 1mm.The above numeral of millimeter level is read by accurate measurement bar (1), and the following numeral of millimeter level is read by gauge outfit (2).
Owing on the table axle, be wound with hairspring, thereby guaranteed that the flank of tooth is the single face engagement, eliminated backlash, improved transmission accuracy.
Effect of the present invention is, 1, reading is directly perceived, accurately, eliminated the measuring error that operation and vision are brought, 2, measurement range is big, easy to operate.
The drawing explanation:
Fig. 1 is the utility model structural representation
Fig. 2 is the gauge head structure synoptic diagram
Fig. 3 is gauge outfit garden stud wheel and an accurate measurement bar tooth bar mesh schematic representation up and down
Below in conjunction with accompanying drawing and use-case, the utility model is further described:
The numbering explanation:
1---accurate measurement bar, 2---gauge outfit, 3---main scale, 4---dial plate, 5---pointer, 6---last garden stud wheel, 7---following garden stud wheel, 8---clamping plate, 9---watchcase, 10---vernier, 11---needle pivot, 12---gear sheet, 13---tooth bars.
The accurate measurement bar (1) of accurate measurement pit gauge is inserted in the tested blind hole, make measuring junction benchmark (A) face of main scale (3), near the datum end face of measured hole, operation accurate measurement bar makes the measuring basis face (B) of accurate measurement bar contact the blind hole bottom.In operating process, the accurate measurement bar moves in the chute of main scale (3), the interior garden stud wheel with the engagement of accurate measurement bar tooth bar of gauge outfit that drive is installed on the main scale rotates, by garden shaft gear sheet (12), make needle pivot, pointer turn over certain angle on dial plate, millimeter value of series on the accurate measurement bar and the following numerical value of millimeter level on the gauge outfit have shown tested blind hole depth.
Claims (2)
1, a kind of digital band table accurate measurement pit gauge, it comprises main scale (3), it is characterized in that, there is sliding tray at middle part at main scale (3), adorning accurate measurement bar (1) in the groove, the accurate measurement bar can slide in groove, on the accurate measurement bar, stud with accurate measurement tooth bar (13), gauge outfit (2) is contained on the blade of main scale (3), in the gauge outfit (2), is contained in upper and lower garden stud wheel (6,7) and the engagement of the tooth bar (13) on the accurate measurement bar in the clamping plate (8), with garden stud wheel up and down coaxial gear sheet (12) drive needle pivot (11), pointer (5) is gone up at dial plate (4) and is rotated.
2, pit gauge according to claim 1 is characterized in that, on the axle of upper and lower garden stud wheel, hairspring (10) is housed, and has eliminated backlash.
