Description

The twin columns electronic digital height gauge

The utility model relates to a kind of twin columns electronic digital height gauge of measuring or ruling usefulness.

Existing former twin columns band table height calipers, 92223651) or " digital pointer height ruler meter " (application number: 93217217) as " column band table height gauge " (application number:, their structure be with the rotation of the shaft gear of counting garden post tooth bar engagement, by the plate gear coaxial with shaft gear, driving the central shaft gear rotates, central shaft gear head end is fastened with pointer cover, pointer, thereby drives the pointer rotation.Read the decimal place of shaft gear and counting garden post tooth bar engagement displacement on the pointer scale dish, mobile integer-bit then relies on the shaft gear on the handwheel spindle nose by worm gear the mechanical counter worm screw to be overturn with the another set of cogwheel gearing of lifting garden post tooth bar engagement drive again and reads.Its mechanical mechanism is complicated.

The purpose of this utility model is, utilizes existing appearance gate technique to replace mechanical type display gauge head on the former twin columns band table height calipers of being made up of pointer, index dial etc., a kind of electronic digital display measurement of the proposition in generation scoring tool.

The purpose of this utility model is achieved in that it is that central shaft gear head end at former twin columns band table height calipers has increased the appearance grid angular transducer that can adjust vertically, and this sensor is electrically connected with LCD.

Its concrete technical scheme is as follows, this twin columns digimatic height gage comprises base, line measuring jaw, measuring claw, chi frame, counting garden post tooth bar, end cap, lifting garden post tooth bar, handwheel and mechanical drive gauge outfit, it is characterized in that, it comprises that is also held a grid angular transducer, the fixed grid 18 of this appearance grid angular transducer is fixed on the train wheel bridge 13 of mechanical drive gauge outfit, the moving grid 17 that holds the grid angular transducer is fixed in moving grid stator 16, and moving grid stator 16 is fastened to the head end of central shaft gear 12, and the fixed grid of above-mentioned capacitor grid transducer is electrically connected with LCD.

Good effect of the present utility model is, the machine driven system and the frame of reference of complicated former twin columns band table height gauge simplified and removed to this twin columns electronic digital height gauge, used the high electronic digit display technique of reliability, made its use more convenient, reading is more directly perceived.

The utility model is described in further detail below in conjunction with accompanying drawing,

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the cut-open view of mechanical drive gauge outfit in the utility model,

Fig. 3 is the synoptic diagram that holds grid angular transducer moving grid,

Fig. 4 is the combination synoptic diagram that holds grid angular transducer fixed grid and LCD,

Fig. 5 is the assembling relationship figure that holds grid angular transducer fixed grid, moving grid and mechanical gauge outfit.

Among the figure, 1-base 2-line measuring jaw 3-measuring claw 4-chi frame 5-counting post tooth bar 6-end cap 7-lifting garden, garden post tooth bar 8-handwheel 9-LCD 10-plate gear 11-shaft gear 12-central shaft gear 13-train wheel bridge 14-elastic washer 15-screw 16-moving grid stator 17-holds grid angular transducer moving grid 18-and holds grid angular transducer fixed grid.

As Fig. 1, Fig. 2, shown in Figure 5, the utility model comprises base 1, line measuring jaw 2, measuring claw 3, chi frame 4, counting garden post tooth bar 5, end cap 6, lifting garden post tooth bar 7, handwheel 8 and mechanical drive gauge outfit, its design feature is, it be with the head end overstriking of the corresponding central shaft gear of former twin columns pointer-type height calipers, lengthening, and fixed the moving grid stator that to adjust vertically with screw 15 at the head end of central shaft gear 12, between central shaft gear and train wheel bridge, be provided with an elastic washer 14 again, to solve the axial float (axial float of pointer height calipers does not influence indicating value, then is fatal to capacitive sensor) of central shaft gear.Holding grid angular transducer fixed grid 18 is to be fixed on the train wheel bridge 13 of mechanical drive gauge outfit with two trip bolts, hold on the bonding what moving grid of the moving grid 17 usefulness double sticky tape paper stator 16 of grid angular transducer, the fixed grid of above-mentioned appearance grid angular transducer is electrically connected with LCD.

Use of the present utility model is, at first determine the measuring basis of testee, shake handwheel then, the rotation of this handwheel has driven the rotation of the shaft gear that is meshed with counting garden post tooth bar, rotate by driving the central shaft gear again with the coaxial plate gear of shaft gear, appearance grid angular transducer fixed grid that is installed on the train wheel bridge 13 and the appearance grid angular transducer moving grid that is bonded in the moving grid stator on the central shaft gear head end are relatively rotated, the size of relative rotation, proportional with the distance that shaft gear moves with counting garden post tooth bar engagement, again by with hold its reading of liquid crystal display displays that grid angular transducer fixed grid is electrically connected.
