Description
Technical field
The utility model relates to a kind of structure of being carried out telescopic linear movement pick-up zeroing locking by screw thread and sawtooth occlusion structure.
Background technology
The performance of usual single redundancy sensor is once-forming after Assembly of the parts.The performance of sensor directly depends on the concise degree of the precision of part machinery processing, the technique of assembling and field worker operation.In recent years along with the continuous increase of family demand, the application of various redundant transducer also got more and more, and this just requires that sensor is while meeting precision, also must meet the flexible adjustment of each remaining null positions.A kind of novel zeroing and the locking mechanism that meet request for utilization is devised for linear movement pick-up (LVDT), the problems such as this structure can realize the flexible adjustment of transducer zeroing position, and that the zero-bit that sensor can be made to overcome bring due to machine error, rigging error, magnetic material performance change etc. overlaps is poor, can not adjust.Facts have proved, this structure realizes simple, easy to operate, has now been successfully applied in the production of redundance linear movement pick-up.
Utility model content
The purpose of this utility model is: propose a kind of zeroing locking mechanism for telescopic linear movement pick-up.
The technical solution of the utility model is: a kind of zeroing locking mechanism of telescopic linear movement pick-up, comprises auris dextra ring 1, set nut 2, right pad 3, left pad 4, connecting rod rest 5, outer cylinder body 6, iron core 7, stator 8, inner barrel 9, left earrings 10; It is characterized in that: stator 8 is fixed with inner barrel 9, and be connected with left earrings 10, unshakable in one's determination 7 are fixed by connecting rod rest 5 and outer cylinder body 6, and be connected with auris dextra ring 1, regulate left earrings 10 to realize null positions with the distance of auris dextra ring 1 by auris dextra ring 1 and the helicitic texture of connecting rod rest 5 to regulate, realized the locking of connecting rod rest 5 and auris dextra ring 1 by the sawtooth occlusion structure of left pad 4 and right pad 3 and set nut 2.
Further, in order to implement the utility model better, fuse can be played realize locking further on left pad 4 and set nut 2.
The utility model has the advantages that: improve the transducer zeroing variation issue brought by machine error, rigging error and magnetic material performance change etc., do not need renewal part, again debug stator condition under, ensure that the accuracy of transducer zeroing position, reduce resetting difficulty, substantially increase product survival rate and production efficiency.

Embodiment
Below in conjunction with Figure of description, the utility model is elaborated, refer to Figure of description 1 ~ Fig. 7.A zeroing locking mechanism for telescopic linear movement pick-up, comprises auris dextra ring 1, set nut 2, right pad 3, left pad 4, connecting rod rest 5, outer cylinder body 6, iron core 7, stator 8, inner barrel 9, left earrings 10; It is characterized in that: stator 8 is fixed with inner barrel 9, and be connected with left earrings 10, unshakable in one's determination 7 are fixed by connecting rod rest 5 and outer cylinder body 6, and be connected with auris dextra ring 1, regulate left earrings 10 to realize null positions with the distance of auris dextra ring 1 by auris dextra ring 1 and the helicitic texture of connecting rod rest 5 to regulate, realized the locking of connecting rod rest 5 and auris dextra ring 1 by the sawtooth occlusion structure of left pad 4 and right pad 3 and set nut 2.
Further, in order to implement the utility model better, fuse can be played realize locking further on left pad 4 and set nut 2.
Embodiment one:
A control method for the zeroing locking mechanism of telescopic linear movement pick-up, step is as follows:
Require: the performance of sensor stator mixes up, stator can not change with relative position unshakable in one's determination, regulates the distance of auris dextra ring and left earrings realize returning to zero and lock this position.
Step 1: by the linear movement pick-up energising of having debug, find the electric null positions of sensor by voltage table test, measure and record this position;
Step 2: the fuse removing fixing left pad 4 and set nut 2, unscrews set nut 2;
Step 3: the serrated face of left pad 4 with right pad 3 is separated, being now threaded of auris dextra ring 1 and connecting rod rest 5 is in freely adjustable state, right pad 3 can in the groove track of auris dextra ring 1 rectilinear motion, but the two must rotate simultaneously;
Step 4: regulate the distance of auris dextra ring 1 and left earrings 10 by the helicitic texture of auris dextra ring 1 and connecting rod rest 5 and measure, making its distance reach the requirement of regulation;
Step 5: fastened by the serrated face of left pad 4 and right pad 3, ensure that the projection of left pad 4 and the groove of connecting rod rest 5 clamp, the projection of right pad 3 and the groove of auris dextra ring 1 clamp simultaneously, and now auris dextra ring 1 and connecting rod rest 5 helicitic texture are locked;
