Abstract
The utility model relates to a caliper digital-display micrometer, which is a high-precision measurement caliper used for measurement in the direction of length. A screw pair is used for the prior micrometer caliper to implement the measurement, the screw pair needs to be twisted circle by circle, the measuring speed is slow and the thread error is included. The product comprises a bow-shaped ruler holder 1 and a quantitative jaw 2 is arranged at one end of the scale holder 1. A capacitive gate slide scale 3 and a digital display 4 are arranged at the other end of the scale holder 1. The product is used as a high-precision measuring tool which can be used conveniently and simply, processes quick measurement, has wide measurement range and has large range.
Description
Technical field: the utility model relates to a kind of measurement slide calliper rule of high-precision length direction metering usefulness.
Background technology: present micrometer callipers uses screw pair to measure, and what needs one enclosed twists, and measuring speed is slow, comprises thread error.
Summary of the invention:
The technical problems to be solved in the utility model: a kind of cassette digimatic micrometer is provided, can measures fast and accurately.
The technical scheme that addresses the above problem:
The cassette digimatic micrometer, its composition comprises: arc chi frame, an end of described chi frame has quantitative pawl, and the other end of described chi frame has the grid slide rule of appearance and device for digit-displaying.
Above-mentioned cassette digimatic micrometer, described appearance grid slide rule comprises the chi frame, is equipped with in the described chi frame to hold the grid scale, described appearance grid scale is equipped with described device for digit-displaying and outer cover thereof outward.
Above-mentioned cassette digimatic micrometer, described device for digit-displaying comprise that strip grate formula capacitance displacement sensor promptly comprises moving grid, fixed grid and LCDs.
Above-mentioned cassette digimatic micrometer has the hole of holding and radial support plate on the described chi frame, described quantitative pawl is contained in or is bonded on the described chi frame, on the described appearance grid slide rule locking nail is housed.
Beneficial effect compared with prior art
1. this product has been concentrated common milscale and and the advantage of digital display calliper.Be that whole frame is similar to outside micrometer, measuring mechanism is similar to digital display calliper, and positioning element adopts the measuring jaw of slide calliper rule.
2. the bow-shaped support in this product provides the rigidity space of between location basal plane and measurement face workpiece or standard component, and both sides arrange that respectively the location basal plane comprises measuring claw and slide rule guide rail (chi frame).Be fixed with the digital display assembly on this chi frame, be stained with the slide rule that holds grid and locate, change in location is converted to capacitance variations, finish measurement function in the moving aiming of chi middle slide of frame.Directly show by digital display, reduce artificial check weighing error, mensuration is accurate, speed is fast.
3. adopt this product, workpiece and scale arranged in series, measured line and slotted line overlap, and structural design meets abbe ' s principle, and error is a second order error, can finish high-acruracy survey fast.
4. adopt the measuring jaw shape and the moving method of slide calliper rule, make this product can obtain the broad scope, using method and slide calliper rule are close, can more accurate, the xsect of intercepting measurement more easily.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is left views of accompanying drawing 2.
Below in conjunction with the concrete embodiment of description of drawings:
