Description
Technical field
The utility model relates to encoder techniques field, relates in particular to a kind of scrambler location compressing tablet and scrambler stationary installation.
Background technology
Scrambler is a kind of device that angular displacement or straight-line displacement is converted to electric signal, absolute encoder is as a kind of position transducer of feeding back absolute position, be the important component part of servo-drive system, its precision and accuracy are directly connected to the performance index of servo-drive system.The location of absolute encoder is the emphasis that guarantees precision.
Scrambler fixed form individual difference is very large, the impact that is subject to use location is a lot, and the fixed form that has a kind of scrambler is to adopt elastic pressuring plate, as shown in Figure 1, by trip bolt, elastic pressuring plate 12 is fixed on the armature spindle of scrambler, on elastic pressuring plate 12, there is pawl 11 and screw 13.This pawl 11 is pressed on the rotor of scrambler, leans on the elastic pressure of elastic pressuring plate 12 that rotor is rotated with axle.When needing equipment in normal operating conditions under vibration environment condition, this elastic pressuring plate 12 elastic deformation when doing axial vibration, make 12 pairs of rotors of elastic pressuring plate pressure in a circumferential direction inhomogeneous, thereby cause rotor and armature spindle to occur relative motion, cause position feedback error.
Utility model content
In view of this, the utility model provides a kind of scrambler location compressing tablet and scrambler stationary installation, to solve in prior art because the technical matters that elastic deformation affects scrambler precision occurs the elastic pressuring plate for regular coding device in the axial direction.
To achieve these goals, the existing scheme proposing is as follows:
A location compressing tablet, is provided with screw on the compressing tablet of described location, and the outer shroud of described location compressing tablet is provided with axial location platform, and the rotor of described axial location platform and described scrambler compresses mutually.
Further, described location compressing tablet is also provided with boss, and described boss and the epitrochanterian gap of described scrambler clamp mutually.
Particularly, the number of described screw is more than or equal to 4.
The utility model also provides a kind of scrambler stationary installation, and described device comprises above-mentioned location compressing tablet, and trip bolt, armature spindle and pedestal; Wherein, described trip bolt is fixed on location compressing tablet on armature spindle by screw, and whole scrambler is fixed on pedestal.
From above-mentioned technical scheme, can find out, the disclosed scrambler of the utility model location compressing tablet, utilize the gap on scrambler armature spindle, on the compressing tablet of location, the boss matching with gap is set, the boss of location compressing tablet and the clamping of the gap on scrambler armature spindle, played the effect of regular coding device; Meanwhile, the outer shroud of location compressing tablet is provided with axial location platform, has increased the contact area of location compressing tablet and scrambler rotor, more solid and reliable in axial location.In a word, the disclosed scrambler of the utility model location compressing tablet is regular coding device better, thereby improves the precision of scrambler.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the elastic pressuring plate structural representation for regular coding device of prior art;
Fig. 2 is the structural representation of the disclosed scrambler of the utility model embodiment location compressing tablet;
Fig. 3 is the structural representation of the disclosed scrambler stationary installation of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of scrambler location compressing tablet, to solve in prior art because the technical matters that elastic deformation affects scrambler precision occurs the elastic pressuring plate for regular coding device in the axial direction.
Concrete, with reference to Fig. 2, Fig. 2 shows the scrambler location compressing tablet that the present embodiment provides, and this location compressing tablet 2 is provided with screw 21, and the number of screw 21 is not limit, and in order to play good fixation, the number of screw 21 be take 4 and above as good.On the outer shroud of fixed outer compressing tablet 2, be provided with axial location platform 23, axial location platform 23 compresses with the rotor of scrambler, has played fixation.On the compressing tablet 2 of location, be also provided with the boss 22 matching with the epitrochanterian gap of scrambler, boss 22 clamps mutually with gap, and scrambler is being played to positioning action in the radial direction.
Due to self design feature of scrambler, on scrambler rotor, with a gap, on the compressing tablet 2 of location, boss 22 is set, just in time when mounted, boss 22 and gap clamping, for scrambler provides radially auxiliary positioning.
Please refer to Fig. 3, Fig. 3 shows a kind of structural representation of scrambler stationary installation, and trip bolt 5 is fixed on location compressing tablet 2 on the armature spindle 31 of scrambler by the screw 21 on the compressing tablet 2 of location.The axial location platform 23 of location compressing tablet 2 outer shrouds compresses the rotor 32 of scrambler, and whole scrambler 3 is fixed on pedestal 4.
The material of main part of location compressing tablet 2 is 2A12 metal duralumin, adopt the fixed form of axial location platform, increased the contact area between location compressing tablet and scrambler rotor, when trip bolt axially fastens, make to locate between compressing tablet and rotor stressed evenly, and can provide radial location by the friction force between axial location platform and rotor.
The location compressing tablet of the scrambler that the present embodiment provides and scrambler stationary installation, by the rotor of axial location platform compression scrambler, for scrambler provides axial location; By boss and the epitrochanterian gap of scrambler on the compressing tablet of location, mutually clamp again, avoided scrambler sliding in the radial direction.By fixing on both direction, reduced the relative motion between scrambler and armature spindle, improved the precision of scrambler.
