Description
Affiliated technical field
The utility model relates to a kind of electronic measuring instrument, especially snap gauge in the variable digital display of measurement range thousand minutes.
Background technology
Along with science and technology development, new and high technology constantly is penetrated into every field.Holding the grid sensing technology is to drop into the new and high technology that a large amount of science and technology strengths grows up for many years, after successfully applying to the measuring tool industry, the parts of traditional measurer is replaced by the novel electron digital display appliance, it have that reading is directly perceived, measurements is simple and easy, efficient is high, data can be connected with computing machine and mechanical type measurer such as processing incomparable advantage, so obtained very fast development and application.
But,, still continuing to use traditional survey instruments such as dead clamp or logical, no-go gage, the development that is far from suitable and produces at present a large amount of when measuring part seam equidimension in industries such as water pump, motor, valves.
Summary of the invention
The development need that be to adapt to modern production, the utility model provide snap gauge in the variable digital display of a kind of measurement range thousand minutes, and it measures convenient and swift, accuracy of reading.
The technical scheme that the utility model adopted is: snap gauge is made up of chi bar, moving jaws, chi frame, plane lock-screw, digital display assembly etc. in the variable digital display of measurement range thousand minutes.Moving jaws is installed in the left side of chi bar, the plane lock-screw is installed on the moving jaws, lock with the plane set nut, two extension springs are installed in the middle part of chi bar and chi frame respectively with screw, the digital display assembly is installed on the chi frame, chi frame and chi bar can be done relative motion, by holding the grid sensing displacement of the lines directly are presented on the LCDs of digital display assembly.Before the measurement, demarcate at measuring room earlier, when measuring endoporus (inner stopper), the chi frame compresses 2～3mm left, and when measuring external diameter (male half coupling), the chi frame compresses 2～3mm to the right, and measuring jaw is put on the measured workpiece, can measure.
The digital display assembly has data-out port, uses special-purpose connecting line, measurement data can be imported that dedicated printer is printed or the input computing machine carries out data processing.
Adopt the beneficial effect of such scheme to be, make that snap gauge has compact conformation in the variable digital display of measurement range thousand minutes, measurement range is big, and is efficient and convenient, degree of accuracy height, plurality of advantages such as economical and practical.

Embodiment
As shown in Figure 1, the moving jaws (2) that connects relatively is installed in the left side of chi bar (1) with it, plane lock-screw (3) is installed on the moving jaws (2), lock with plane set nut (6), two extension springs (8) use flat head screw (9) to be installed in the middle part of chi bar (1) and chi frame (11) respectively, chi bar (1) is packed in the groove of moving jaws (2) and chi frame (11), on moving jaws (2) and chi frame (11), two pieces of set screw (5) are installed respectively, be used to regulate moving jaws (2), the glade plane space of chi frame (11) and chi bar (1), two pieces of lock-screws (4) are contained in the upper end of locking chi frame (11) and moving jaws (2) respectively, digital display assembly (7) is installed on the chi frame (11), chi frame (11) can be done relative motion with chi bar (1), by holding the grid sensing displacement of the lines directly is presented on the LCDs of digital display assembly (7).
Moving jaws (2) can move and fixes to chi bar (1) left end according to the size of measured workpiece size, thereby before measuring, need to demarcate at measuring room, when measuring endoporus (inner stopper), chi frame (11) compresses 2～3mm left, and when measuring external diameter (male half coupling), chi frame (11) compresses 2～3mm to the right, measuring jaw is put on the measured workpiece, can measures.
Digital display assembly (7) has data-out port, uses special-purpose connecting line, measurement data can be imported that dedicated printer is printed or the input computing machine carries out data processing.
As can be seen from Figure 2, there are two grooves at chi frame (11) middle part, and every groove subtend one end has a screw, and the two ends of chi frame (11) have the stopper slot of one 5 * 5mm respectively.
Claims (3)
1, snap gauge is made up of chi bar, moving jaws, chi frame, plane lock-screw, digital display assembly in the variable digital display of measurement range thousand minutes, it is characterized in that: moving jaws is installed in the left side of chi bar, the plane lock-screw is installed on the moving jaws, lock with the plane set nut, two extension springs are installed in the middle part of chi bar and chi frame respectively with screw, the chi bar is packed in the groove of moving jaws and chi frame, and two pieces of set screw respectively are installed on moving jaws and chi frame, and the digital display assembly is installed on the chi frame.
