Abstract
The utility model belongs to machinery design technology, and relates to improvement on a sensor zero-setting structure. The disassembly-free type sensor zero-setting structure comprises zero-setting screws (1), a zero-setting cover plate (2), spring washers (3) and flat washers (4). The disassembly-free type sensor zero-setting structure is characterized in that each zero-setting screw (1) is a step type structure with one end of the zero-setting screw provided with threads; the zero-setting cover plate (2) is provided with kidney-shaped holes, clamping grooves for rotation, positioning bosses and adjusting columns; the adjusting columns of the zero-setting cover plate (2) are clamped on outer sides of lugs of a sensor; and each zero-setting screw (1) penetrates through the spring washer (3), the flat washer (4), the kidney-shaped hole of the zero-setting cover plate (2) and the lug of the sensor so as to fix the zero-setting cover plate (2) and the sensor. When the disassembly-free type sensor zero-setting structure is utilized to perform zero setting on the sensor, only the zero-setting screws need to be unscrewed and the zero-setting cover plate needs to be rotated, and thus disassembly-type sensor zero setting is realized, operation space for adjustment is reduced, the maintenance performance of the equipment is improved, and a requirement of downsizing missile type products is satisfied.
Description
Technical field
The utility model belongs to mechanical designing technique, relates to the improvement to sensor zero setting structure.
Background technology
At present, when missile-borne sensory unit zero-bit regulates, need pull down sensor protective cover or cover sheet, unscrew sensor auricle mounting screw, rotation sensor carries out zero-bit adjusting.Along with guided missile series products volume is more and more less, the operating space that can offer zero-bit adjusting is more and more narrower and small, and sight line cannot reach installation position, and traditional regulative mode can not meet design requirement.
Utility model content
The purpose of this utility model is: propose a kind of avoid dismantle sensor zero setting structure, constantly dwindle in situation the requirement that transducer zeroing adjustment operation space is little to meet guided missile series products volume.
The technical solution of the utility model is: a kind of avoid dismantle sensor zero setting structure, comprise two zeroing screws 1, zeroing cover plate 2, spring washer 3 and plain washer 4, and it is characterized in that: zeroing screw 1 is staircase structural model, TOE; On zeroing cover plate 2, there are mounting hole, rotation draw-in groove and positioning boss and adjustable column; The adjustable column of zeroing cover plate 2 is stuck in sensor auricle outside, and zeroing screw 1 through spring washer 3, plain washer 4, the zeroing mounting hole of cover plate 2 and the auricle of sensor, fixes zeroing cover plate 2 and sensor with the threaded end of the screw 1 that returns to zero successively.Zeroing cover plate 2 has two adjustable columns, can forward and reverse promotion sensor auricle.
The utility model has the advantages that: when the utility model carries out zero-bit adjusting to sensor, only need unscrew zeroing screw, rotate zeroing cover plate, realizing avoid dismantle transducer zeroing regulates, reduce and regulated with operating space, improve the maintainability of equipment, met the requirement that guided missile series products volume constantly dwindles.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of avoid dismantle sensor of the utility model zero setting structure;
Fig. 2 is zeroing covering plate structure schematic diagram;
Wherein, 1-zeroing screw, 2-zeroing cover plate, 3-spring washer, 4-plain washer.
Embodiment
Below the utility model is described in further details,
Referring to Fig. 1,2, a kind of avoid dismantle sensor zero setting structure, comprises two zeroing screws 1, zeroing cover plate 2, spring washer 3 and plain washer 4, it is characterized in that: zeroing screw 1 is staircase structural model, TOE; On zeroing cover plate 2, there are mounting hole, rotation draw-in groove and positioning boss and adjustable column; The adjustable column of zeroing cover plate 2 is stuck in sensor auricle outside, and zeroing screw 1 through spring washer 3, plain washer 4, the zeroing mounting hole of cover plate 2 and the auricle of sensor, fixes zeroing cover plate 2 and sensor with the threaded end of the screw 1 that returns to zero successively.Zeroing cover plate 2 has two adjustable columns, can forward and reverse promotion sensor auricle.
The step surface jam sensor auricle of zeroing screw 1, realize the location of the fixing of sensor and zeroing screw 1, eliminate with plain washer 4 and spring washer 3 in gap between zeroing screw 1 and zeroing cover plate 2, and while spring washer 3 is the mistake orientation problem with sensor auricle and the 2 liang of surface of contact of cover plate that return to zero in order to solution zeroing screw 1.
When sensor is carried out to zero-bit adjusting, only need unscrew zeroing screw 1, rotate zeroing cover plate 2, realizing avoid dismantle transducer zeroing regulates, reduce and regulated with operating space, improve the maintainability of equipment, realized avoid dismantle transducer zeroing and regulated, met guided missile series products volume and constantly dwindled and the requirement that cannot see sensor auricle mounting screw.
Claims (2)
1. an avoid dismantle sensor zero setting structure, comprises two zeroing screws (1), zeroing cover plate (2), spring washer (3) and plain washer (4), it is characterized in that: zeroing screw (1) is staircase structural model, TOE; On zeroing cover plate (2), there are mounting hole, rotation draw-in groove and positioning boss and adjustable column; The adjustable column of zeroing cover plate (2) is stuck in sensor auricle outside, zeroing screw (1) through mounting hole and the sensor auricle of spring washer (3), plain washer (4), zeroing cover plate (2), fixes zeroing cover plate (2) and sensor with the threaded end of the screw that returns to zero (1) successively.
2. a kind of avoid dismantle sensor zero setting structure according to claim 1, is characterized in that: zeroing cover plate (2) has two adjustable columns, can forward and reverse promotion sensor auricle.
