Abstract

The utility model provides a novel diamond-shaped electronic digital caliper, which is mainly composed of a capacitance sensor component, a liquid crystal display, a caliper body and a caliper frame. The utility model is characterized in that the sliding matched parts of the two ends of the cross sections of the caliper body and the caliper frame are diamond shaped; one side of the longitudinal axial line of the face of the caliper frame near to the front and back of the diamond point is respectively provided with a through hole, the middle of which is provided with a thread; the upper end of the thread is perpendicular to the middle part of the through hole, and is transversely provided with two small slots; sinking head clearance adjusting screws , which are matched with the threads of the through holes , are screwed inside the through holes. The utility model solves the problem that the error of the displayed value and the measuring precision are affected due to the fact that the matched clearance of the present caliper can not be adjusted, and thus the utility model makes the displayed data of the measured the result stable and reliable. The matched clearance of the utility model can be adjusted and is easy to be adjusted. Therefore, the utility model is convenient to be used, can reduce the error of the displayed value and can improve the measuring precision. Thus, the utility model is applicable for the measuring workpieces in the mechanical processing industry.

Description

A kind of novel rhombus digimatic calipers

(1) technical field:

The utility model belongs to surveying instrument, specifically a kind of novel rhombus digimatic calipers.

(2) background technology:

Existing ordinary electronic digital display calliper, its physical construction partly be blade with the chi frame between exist different gaps, even the digimatic calipers of diamond structure can not be adjusted the gap between blade and the chi frame, influence the error of indication and measuring accuracy.

(3) utility model content:

The purpose of this utility model provides a kind of novel rhombus digimatic calipers, and the glade plane space between its blade and the chi frame is adjustable, and the slide calliper rule of this structure can reduce the error of indication and improve measuring accuracy, make measurement result more reliable.

In order to achieve the above object, the technical measures that the utility model is taked are: this digital display calliper comprises the measuring head that capacitor grid transducer assembly, LCD and blade and chi frame constitute, it is characterized in that: the part that is slidingly matched at blade and chi frame xsect two ends assumes diamond in shape, chi frame front longitudinal axis one side respectively has a through hole near the other front and back of water chestnut point, the middle part of through hole is threaded, the thread segment upper end laterally has the twice stria perpendicular to the middle part of through hole, and the countersunk head gap adjustment screws that matches with screw thread in the through hole is spun in the through hole.

The utility model has the advantages that: the mobile space of blade and chi frame can be adjusted and be easy to adjust, and can reduce the error of indication, improve the accuracy of measuring, and makes the measurement result data presented reliable and stable.

Fig. 2 is the installation site cut-open view of case moving grid assembly 2 interior capacitor grid transducers among Fig. 1.

Fig. 3 is the mechanical part view that takes down among Fig. 1 behind the case moving grid assembly.

Fig. 4 is that blade cooperates with the chi frame and the cut-open view of clearance adjusting screw installation site among Fig. 3.

(5) embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail: in Fig. 1, the 1st, LCDs, the 2nd, case moving grid assembly, the 3rd, stop screw is used for the dogging beam mouth, and the 4th, the switching button of metric and English measurement unit, the 5th, 1.5V button cell, the 6th, front pressuring plate, the 7th, pit gauge, the 8th, the zero setting button, the 9th, power switch, the 10th, chi frame, the 11st, blade, chi frame and blade are for being slidingly matched, and the chi frame that relatively moves can change the distance of measuring mouthful both ends of the surface and pit gauge and chi frame tail both ends of the surface simultaneously.Fig. 2 is the installation site cut-open view of case moving grid assembly 2 capacitor grid transducers among Fig. 1, among the figure, and the 12nd, the self tapping gib screw, the 7th, the xsect of pit gauge, the 13rd, fixed grid is contained in the groove of blade, the 14th, spring shim, the 2nd, case moving grid assembly is fixed on the chi frame, and moving, fixed grid face is installed relatively, between leave the gap, the attachable mechanical stage frame, moving grid also is moved thereupon, and measurement data shows in LCDs through the sensor internal processing of circuit.Capacitor grid transducer and assembly thereof are the prior aries that generally adopts during present digital display is measured.

Fig. 3 is the mechanical part view that takes down among Fig. 1 behind the case moving grid assembly, and Fig. 4 is that blade cooperates with the chi frame and the cut-open view of clearance adjusting screw installation site among Fig. 3, also is distinguishing characteristics of the present utility model place.Wherein, the 15th, the cross recessed countersunk head sscrew of gap adjustment usefulness, have two, respectively adorn one before and after a side of longitudinal axis, specification is M1.6, the 17th, the through hole of assemblage gap set screw, the aperture is φ 2, and design is by blade and chi frame are slidingly matched water chestnut point partly, and the middle part of through hole 17 is threaded, gap adjustment screws 15 is spun in the screw of through hole, and turn set screw up and down can be adjusted the gap that is slidingly matched of blade and chi frame.The thread segment upper end laterally has twice stria 16 perpendicular to the middle part of through hole in the through hole, the width 0.2mm of notch, and its effect is to make to adjust easily, is easy to adjust, and can eliminate unnecessary gap.
