Abstract
The utility model discloses an axial motion fine-adjusting device for a displacement sensor. The axial motion fine-adjusting device comprises a sliding rod, a spring, a base and a fine-adjusting nut. The axial motion fine-adjusting device is characterized in that the sliding rod passes through the spring, the base and the fine-adjusting nut in sequence. One end of the sliding rod is designed with a sensor fixing position, and the other end of the sliding rod is provided with a boss, a polished rod and threads in sequence. The outer diameter of the boss is greater than the inner diameter of the spring. The cross section of the polished rod between the boss and the threads is square, the base is provided with a square through hole, and the square side length of the cross section of the polished rod is slightly less than the square side length of the through hole in the base. The axial motion fine-adjusting device can be used for performing fine-adjustment on axial motion of the displacement sensor fixed on the sliding rod while ensuring that the displacement sensor does not rotate, and is simple and convenient in operation.
Description
Technical field
The utility model relates to a kind of device, in particular for the device of displacement transducer axially-movable fine setting.
Background technology
On June 5th, 2013, " a kind of hyperchannel full-automatic concrete convergent-divergent instrument " patent No. of bulletin was in ZL201220557247.X, to propose to adopt displacement transducer and Acquisition Instrument to be used in conjunction with to replace dial gauge, and then play raising precision, reduce labor intensity of operating staff and workload, avoid the effect of personnel's operate miss.But in patent, do not describe in detail how to realize displacement transducer is carried out to axially-movable fine setting.
Utility model content
The utility model provides a kind of displacement transducer axially-movable micromatic setting.
The utility model solves the technical scheme that its technical matters adopts: a kind of displacement transducer axially-movable micromatic setting, comprises slide bar, spring, base and fine-tuning nut.It is characterized in that, slide bar is successively through spring, base and fine-tuning nut.
Described slide bar one end is designed with sensor fixed bit, to slide bar other end direction, is designed with successively boss, polished rod and screw thread.
Described boss external diameter is greater than spring inside diameter.
Polished rod cross section between described boss and screw thread is square, has square through-hole on base, and the polished rod cross section square length of side is slightly smaller than the square length of side of base plate through holes.
The beneficial effects of the utility model show as:
By rotary fine adjustment nut, can finely tune slide bar axially-movable.When displacement transducer is parallel, be fixed on (maintenance is relative with slide bar static) on slide bar, by rotary fine adjustment nut, can finely tune displacement transducer axially-movable, guarantee that displacement transducer does not rotate simultaneously, simple and convenient.
Accompanying drawing explanation
Fig. 1 is the utility model displacement transducer axially-movable micromatic setting structural drawing;
Fig. 2 is the utility model Slide bar structure figure;
In figure: 1-slide bar, 2-spring, 3-base, 4-fine-tuning nut, 1.1-sensor fixed bit, 1.2-boss, 1.3-polished rod, 1.4-screw thread.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is done further and described in detail.
Referring to Fig. 1, a kind of displacement transducer axially-movable micromatic setting, comprises slide bar 1, spring 2, base 3 and fine-tuning nut 4.Described slide bar 1 is successively through spring 2, base 3 and fine-tuning nut 4.As seen from Figure 2, described slide bar 1 consists of sensor fixed bit 1.1, boss 1.2, polished rod 1.3 and screw thread 1.4.Wherein sensor fixed bit 1.1, for fixed displacement sensor, makes displacement transducer and slide bar keep relative static, regulates displacement transducer to make its axially-movable direction parallel with slide bar.
During use, first that base 3 is fixing.Because boss 1.2 external diameters are greater than spring 2 internal diameters, spring 2 cannot move to boss 1.2 opposite sides when compressed.Meanwhile, because the polished rod 1.3 cross section square length of sides are slightly smaller than the base 3 through hole square length of sides, can guarantee that polished rod 1.3 is through after base 3, slide bar 1 does not rotate, but can be free to slide vertically.
Rotary fine adjustment nut 4 makes it to the direction motion near base 3, when fine-tuning nut 4 contacts with base 3, continuing rotary fine adjustment nut 4 will shrink spring 2 pressurizeds in base 3 left sides, and then the Distance Shortened between boss 1.2 and base 3, slide bar 1 integral body moves to base 3 right sides, displacement transducer also and then moves right, due to fine-tuning nut 4 rotate a circle displacement transducer move right a pitch of thread from, thereby completed the fine setting to displacement transducer axially-movable.
When spring 2 is during in compressive state, rotary fine adjustment nut 4 makes it to the direction operation away from base 3, the elastic force of spring 2 can make the distance between boss 1.2 and base 3 become large, slide bar 1 integral body moves to base 3 left sides, displacement transducer is also and then moved to the left, due to fine-tuning nut 4 rotate a circle displacement transducer be moved to the left a pitch of thread from, thereby completed the fine setting to displacement transducer axially-movable.
The utility model displacement transducer axially-movable micromatic setting, utilize the elastic deformation of spring self, and screw thread rotation is advanced for one week or the characteristic of a slow astern screw thread, by the screwing and loosen the fine setting realizing displacement transducer axially-movable of fine-tuning nut, guarantee that displacement transducer does not rotate simultaneously.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
