Abstract
The utility model relates to an assembly scale for induction synchronizers, which is used for measuring displacement. The assembly scale for induction synchronizers is adapted for digital display and numerical control system. The assembly scale for induction synchronizers is characterized in that the structural form that the outer terminal of the winding on a fixed ruler and the outer terminal of the winding on a slide ruler are positioned at the same side is adopted. The slide ruler directly slides on the fixed ruler by means of the boss positioned on the slide ruler, and an elastic element is arranged on the slide ruler. The utility model has the advantages of compact structure, small size, high measuring precision, simpler manufacturing technology than the prior art and degressive cost.
Description
A kind of inductosyn numerical control, digital readout system, that be used for Displacement Measurement assembling chi that is applicable to, it mainly is made up of institutes such as being sleeved on scale in the housing, that be provided with winding on it and slide rule.
The principle of work of this inductosyn assembling chi is as follows: because the winding that is provided with certain plane geometric shape and communicates from beginning to end on scale and the slide rule, after giving winding energising, promptly produce magnetic field with certain rule, when relative this winding of another winding in being in this magnetic field moves, then induce electric signal, can converse displacement according to electric signal.
Accompanying drawing 1 is an example of existing inductosyn assembling chi structure, as shown in Figure 1: scale (2 ') is fixed on the base (1 '), slide block (6 ') is in the slideway that the end is sat and scale (2 ') is formed and can slides along the cut lengths direction, utilize web member that slide rule (3 '), transmission plate (7 '), slide block (6 ') are fixed together, during Displacement Measurement, external movement is passed to slide rule (3 ') by transmission plate (7 ').Cover plate (9 ') tightens together by securing member and base (1 '), and cover plate (9 ') is provided with shrouding (8 '), influences precision in order to avoid dirt ash and foreign material fall in the assembling chi.
Existing known assembling chi also has some other version, this piece of writing is not in narration one by one, but the following weak point of these assembling chi ubiquities: the external terminal of (1) scale and slide rule makes scale and slide rule have to stagger mutually not in the same side, causes assembling chi overall dimensions bigger.(2) since the measuring accuracy of inductosyn assembling chi depend primarily between scale winding and slide rule winding between the accuracy of coupling gap, for obtaining this gap accurately, slide rule is slided along a high-precision slideway, because the requirement on machining accuracy of slideway is very high, so production cost is higher.
The purpose of this utility model is to overcome weak point of the prior art and provides that a kind of overall dimensions is less, producing cost is low and the higher inductosyn assembling chi of output electric signal quality.
The purpose of this utility model reaches by following measure: the external terminal of the external terminal of scale winding and slide rule winding is arranged in the same side, both sides are provided with boss below slide rule, the surface of contact of this boss and scale is as the slideway of slide rule motion, flexible member is installed on slide rule, to guarantee that a power of pressing to scale that continues is arranged, the slide rule boss is contacted all the time with scale.
The assembling chi that the utility model is designed, said flexible member is made up of the spring and the steel ball that are installed in the cylinder type hollow body, also can be flat spring.The boss on both sides can be formed by the liner plate that is installed in the slide rule both sides below the slide rule, also can directly process during slide rule in processing, and boss also can be arranged on the scale, method be arranged on slide rule on identical.In addition directly flexible member as the transmission connection piece that external movement is passed to slide rule.
The drawing of accompanying drawing is described as follows:
Fig. 1 is existing inductosyn assembling chi cross-sectional view.
Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is a front view of the present utility model.
The utility model elaborates below in conjunction with accompanying drawing:
As Fig. 2, shown in Figure 3: as to utilize securing member to be fastened on the housing (1) scale (2), packing into from the end of housing then, it is provided with the slide rule (3) of flexible member (7), form by spring in the cylinder type hollow body and steel ball by being installed in for the shown flexible member of this figure, four arms of angle at slide rule (3) are provided with four liner plates formation boss (6) along the slide rule length direction, the height of boss should adapt with the coupling gap of scale winding and slide rule winding, the surface of contact of boss (6) and scale (2) directly as the slideway of slide rule (3) motion, to make the external terminal (5) of slide rule winding and the external terminal (4) of scale winding be positioned at the same side during dress slide rule (3), only in this way could guarantee using under the same scale situation, make assembling chi overall dimensions minimum.Housing (1) can be assembled by a plurality of parts, also integral body.
When using this assembling chi, raise shrouding (8), the connector that is fixed on the measuring object is stretched in the housing (1), be fixed together with slide rule (3), when measuring object moved, slide rule (3) is movement therewith also, produce electric signal, can draw displacement by converting.
The utility model has following advantage compared to existing technology:
1, be positioned at the assembling form of homonymy owing to the external terminal of external terminal that has adopted the scale winding and slide rule winding, make and assemble the chi compact conformation, overall dimensions dwindles.
2, directly utilize the slideway of the surface of contact of the boss that is arranged on below the slide rule and scale, need not to reprocess high-precision slide block and slideway, thereby both guaranteed the positional precision of slide rule, make the production cost reduction again as the slide rule motion.
3, slide rule slides on the scale plane all the time, and the factor that influences scale winding and slide rule winding coupled gap is less, and it is higher therefore to export the electric signal quality.
Claims (4)
1, the inductosyn assembling chi used of a kind of Displacement Measurement, it is applicable to numerical control, digital readout system, it is made up of the scale (2) and slide rule (3) and the shrouding (8) etc. that are sleeved in the housing (1), on scale (2) and slide rule (3), be equipped with winding, of the present utility model being characterised in that: the winding external terminal (5) on winding external terminal (4) on the scale (2) and the slide rule (3) is positioned at homonymy, both sides are provided with boss (6) below slide rule (3), and flexible member (7) is installed on slide rule (3).
2, assembling chi according to claim 1 is characterized in that: the boss (6) on both sides can the liner plate of both sides forms below the slide rule by being installed in below the slide rule (3), also can directly process boss when processing slide rule (3).
