Description
The utility model is the sensor that belongs to the microelectronics display unit, is used on the lathe.
The present linear inductosyn of using, difficulty is very big on installing and using, and solve on the lathe just difficulty more of spreading, and difficult more.According to the supporting actual requirement of machine tool plant,, it is supporting to solve machine tool plant's digital display device, and what need is the long chi of novel digital display assembly type of adjustable any spreading.Currently used combination ruler is all shorter, and what have can spreading, is difficult for meeting the demands, and installs pretty troublesome.Because linear inductosyn is the quite high linear measurement instrument of a kind of precision, thereby the requirement that it is installed and spreading is debugged is very high, has sent improperly in the installation, will have a strong impact on the precision of instrument, therefore the Installation and Debugging and the spreading of digital display device bring very big difficulty to the user concerning the user.Often do not reach result of use.
The purpose of this utility model is a kind of aluminum alloy frame spreading formula linear inductosyn combination ruler of design, can adjust, installation, spreading be easy, the light outward appearance of body U.S., strong interference immunity, reliable in quality, precision height.
The utility model mainly adopts the linear inductosyn of domestic production, utilizes magnetic induction principle, and the straight-line displacement amount accuracy is converted to the signal of telecommunication, and it finishes the detection of precision positions.The structure chart of this combination ruler is as shown in Figure 1, 2: mainly be made up of scale, slide rule, chi frame, billet, blanking cover plate, the plate that is connected and fixed, hold-down screw, chi frame cover plate, location jackscrew, slide rule frame, miniature bearing, bearing bearing pin, holding screw, scale lead, slide rule lead, rubber weather strip etc.This combination ruler is to improve on the basis of former patent aluminum alloy frame linear inductosyn combination ruler, and its main feature has increased the plate that is connected and fixed, and links with the datum clamp face of it and machine tool guideway.The plate bottom surface that is connected and fixed is a pin-and-hole with the column type of two open types, inserts straight pin with the pin-and-hole location, can connect the every section plate that is connected and fixed; There are two circular arc type projectioies and dove-tail form feather key in the front, play the positioning and fixing effect, can contact with the dovetail groove before and after the chi frame, when adjust every section chi the spreading precision time, guarantee that with the location jackscrew is fixing every section chi frame is on same parallel lines, like this can be easily spreading arbitrarily, satisfy instructions for use.Chi frame profile as shown in Figure 2; The back of chi frame has dovetail groove, can join with the dovetail feather key of the plate that is connected and fixed, and chi frame inner bottom surface has dovetail groove to be used for installing billet.One side has the groove on dovetail inclined-plane, is to be used for installing chi frame cover plate, can prevent that like this chi frame cover plate from falling down.Billet end face both sides have gradient, can insert in the dovetail groove in the chi frame, with it fixedly scale can prevent that the loosening heat with the assurance chi of the scale expansion factor of splashing is consistent.Scale, slide rule do not change: scale has a continuous winding, and its cycle guarantees that strict characteristic is 2mm, and the nominal length of scale is 250mm, can be contained in the combination ruler by polylith.It is two groups of Sim and cos that slide rule has two groups of windings, on a slide rule, occur, be contained in the chi frame and be coupled with scale, scale, slide rule keep the 0.25mm gap, have formed the position transformer of a plane exactly, in this transformer, scale or slide rule can be done excitatory limit, if excitatory to slide rule, just produce induced potential in the scale, otherwise too.Induced potential has such characteristic, relative position between its large and small and slide rule winding is corresponding, its variation is the cycle of scale winding, therefore when scale, slide rule during in vertical or horizontal relative motion, induced potential also changes with the cycle, induced signal is delivered to by amplification in the digital display meter of corresponding circuit or system and gone,, the actual range of displacement can be shown with number in digital display meter through the conversion of function transformer.Scale is screwed on the billet in the chi frame, and slide rule is fixed on the slide rule frame, and miniature bearing is contained in the bearing groove of slide rule frame.The slide rule frame is contained in can be toward anti-motion in the interior gathering sill of chi frame.Several scales with the lead series connection or and be together in series, connect with digital display meter by amplifier and excitation device; Adaptation can be in combination ruler, also can be outside combination ruler.Chi frame cover plate is contained in the chi frame and is with in the dovetail surface groove, and all there is the circular groove of open type on the every limit of chi frame and chi frame cover plate counterpart place, can play the dustproof and sealing function of anti-bits after rubber weather strip is packed into.The plate that is connected and fixed is contained on the datum level of machine tool guideway, and the chi frame is contained on the dovetail feather key of the plate that is connected and fixed, like this chi frame can be on the dovetail feather key move left and right, thereby reach the purpose of any spreading.
The utility model and the contrast of existing technology, great changes have taken place from mounting means, solved the difficulty of inductosyn spreading, and masty safety prevention measure, and this combination ruler has following advantage:
One, compactness rational in infrastructure, modern design, outward appearance U.S., body is little, body is light, strong interference immunity, reliable in quality precision height, good airproof performance, safe and reliable not fragile chi, install simple, easy to use, cost is low;
Two, be not subjected to environmental constraints, be not afraid of oil, water, dirt and normally move;
Three, be not subjected to length restriction, every section chi reaches three meters, and integral body can reach tens meters;
Four, maintenance, adjust easy for installation, the cycle that alleviates workmen's labour intensity and preform;
Five, be fit to the transformation of the supporting and old lathe of the big-and-middle-sized lathe of machine tool plant, shorten the set-up time, can answer the supporting use of digital display meter with the various model sense of domestic production synchronized.
