Description
Technical field
The utility model relates to digital display calliper, particularly a kind of digital display calliper that possesses Novel movable gate wire plate.
Background technology
The digital display calliper of prior art, for ensureing the fit-up gap of moving grid and fixed grid, conventionally in moving grid wiring board both sides process Milling Process, process two steps, bring thus a series of adverse consequencess, be mainly manifested in: (1) moving grid circuit board, because the error that Deformation in Milling Process and uneven thickness cause is the main source of digital display calliper error, even causes moving grid to be scrapped, and cost of products is improved greatly; (2) thus reduce the installation distortion of aggravation moving grid because Milling Process can cause moving grid integral rigidity; (3) in machining process, wiring board is easily weighed wounded, is polluted, and makes chip side determine qualification rate and reduces; (4) because the moving grid machined surface moisture absorption expands, capacitor block pitch being increased, is the main cause that in digital display calliper use procedure, error increases gradually; (5) due to machine work, lengthen the production cycle, reduce production efficiency, cost of products is increased.
Mono-kind of CN2389348Y possesses the digital display calliper of Novel movable gate wire plate and New ruler frame, this patented claim is the fit-up gap that ensures moving grid and fixed grid, do not take at moving grid wiring board both sides Milling Process step, and take chi frame part position to sink, surface of subsidence is as the mode of the installed surface of Novel movable gate wire plate, but can introduce equally mismachining tolerance, improve processing cost.
Utility model content
The purpose of this utility model is intended to overcome the deficiencies in the prior art, and provide one to eliminate the caused error of moving grid wiring board machine work, strengthen its rigidity to prevent that distortion is installed, improved Product Precision qualification rate and production efficiency and reduced the digital display calliper that possesses Novel movable gate wire plate of production cost.
The technical scheme that realizes the utility model object is:
A kind of digital display calliper that possesses Novel movable gate wire plate, comprise blade, chi frame, display unit and fixed grid, unlike the prior art: also comprise the Novel movable gate wire plate being formed by moving grid line function plate and moving grid sensor board, moving grid circuit is arranged on moving grid sensor board, the width of moving grid sensor board is less than the width of moving grid line function plate, the mode that moving grid sensor board combines by viscose glue and welding is arranged on the middle part of moving grid line function plate bottom surface, and mate equipped with moving grid line function plate, the long side direction of moving grid line function plate and moving grid sensor board has just formed two steps like this, two steps are installed on chi frame as the installed surface of Novel movable gate wire plate, and move with chi frame.
On described moving grid line function plate and moving grid sensor board, be respectively equipped with location and installation hole one to one, play the effect of location, can ensure the accuracy of moving grid line function plate and moving grid sensor board relative position in the time of assembling.
Existing moving grid wiring board is divided into moving grid line function plate and moving grid sensor board two parts by the utility model, the width of moving grid sensor board is less than the width of moving grid line function plate, two plate stacks are bonded as one, two steps are just formed at the long side direction of moving grid wiring board like this, ensure the fit-up gap of moving grid and fixed grid, avoid mach link, eliminate the error that moving grid wiring board causes because of machining distortion and uneven thickness, even cause wiring board to scrap, improve the integral rigidity of wiring board, greatly reduce the installation distortion of wiring board, also eliminated the disadvantage that digital display calliper error is increased gradually because of the machined surface moisture absorption, shorten the production cycle, precision and the qualification rate of product are improved.
