Description
Technical field
The utility model relates to technical field of measuring equipment, is specifically related to a kind of magnetoelectricity series measuring mechanism.
Background technology
Along with the continuous progress of science and technology, the machinery and equipment of high-accuracy high-efficiency rate is constantly releasing market, because its automaticity is more and more higher, therefore the heat receiving enterprise is held in both hands, in the process realizing robotization, machine self is typically provided with various instrument, in process of production, production unit needs to measure in real time instrument, to ensure its precision.The measuring mechanism of an instrument is in the market varied, but its structure is comparatively complicated, cause price costly, cause the straight line of production cost to rise, how therefore a kind of simple and practical measurement mechanism be provided, become the utility model technical issues that need to address.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of measuring mechanism, by changing inner structure, makes measuring mechanism have stronger cost advantage, and dirigibility strengthens.
The technical solution of the utility model is as follows:
A kind of magnetoelectricity series measuring mechanism, comprise the moving coil of rectangular configuration, the two ends of described moving coil are connected to rotating shaft, a cylinder-shaped iron core is provided with in the centre of described moving coil, be provided with the pole palm at the two ends, bottom side of described cylinder-shaped iron core, in described pole, palm is connected with permanent magnet, and described rotating shaft is arranged with rotary sleeve, described rotary sleeve is equipped with pointer, and the both sides of described rotary sleeve are linked with balance bob; Be provided with hairspring in the end of each described rotating shaft, described hairspring reverse-winding is in described rotating shaft, and one end of hairspring is connected with described moving coil, and the other end is fixed in described rotating shaft by snap close.
Beneficial effect: the utility model is by above technical scheme, and it is ingenious that the utility model has structure, the advantage that cost is low, in actual production use procedure, handled easily person measures arbitrarily, and small volume, and dirigibility is strong.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of a kind of magnetoelectricity series measuring mechanism disclosed in the utility model embodiment.
Numeral and the corresponding component title represented by letter in figure:
1, permanent magnet; 2, the pole palm; 3, cylinder-shaped iron core; 4, moving coil; 5, hairspring; 6, pointer; 7, balance bob; 8, return to zero device.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
A kind of magnetoelectricity series measuring mechanism, comprise the moving coil 4 of rectangular configuration, the two ends of described moving coil 4 are connected to rotating shaft, be provided with a cylinder-shaped iron core 3 in the centre of described moving coil 4, described measuring mechanism is also provided with a support, and described cylinder-shaped iron core 3 is fixed on support, like this, form certain gap between described moving coil 4 and described cylinder-shaped iron core 3, namely cylinder-shaped iron core 3 is positioned at the centre of described moving coil 4, and described moving coil 4 can be made to rotate in air gap; The pole palm 2 is provided with at the two ends, bottom side of described cylinder-shaped iron core 3, the described pole palm 2 is connected with permanent magnet 1, this structure is adopted to effectively reduce magnetic resistance, and make to produce uniform radial pattern magnetic field in the air-gap between the pole palm 2 and iron core, in addition, the advantage of this structure is, along the surface of described cylinder-shaped iron core 3, magnetic induction density is equal everywhere, and direction is then perpendicular with cylindrical surface.
Described rotating shaft is arranged with rotary sleeve, described rotary sleeve is equipped with pointer 6, the both sides of described rotary sleeve are linked with balance bob 7; Hairspring 5 is provided with in the end of each described rotating shaft, described hairspring 5 reverse-winding is in described rotating shaft, one end of hairspring 5 is connected with described moving coil 4, the other end is fixed in described rotating shaft by snap close, when described moving coil 4 deflects, described pointer 6 can be driven to deflect, thus can measured size be shown.
Illustrate whole implementation process below, after moving coil 4 passes to electric current, under the magnetic fields of permanent magnet 1, produce rotating torque and coil is rotated, the moment of reaction is produced by hairspring 5, described hairspring 5 is two, respectively around the two ends of described rotating shaft, and around on the contrary, hairspring 5 one end is connected with moving coil 4, the other end is fixed in rotating shaft, and the effect of hairspring 5 had both produced retroaction square, electric current is introduced into described moving coil 4 again simultaneously.
In order to the position that the pointer 6 on measuring mechanism can be made to be in zero before the use, the present embodiment is equipped with a zeroing device 8 in rotating shaft, and one end of zeroing device 8 is connected with hairspring 5 nearby, to form reference.
The measuring mechanism that the present embodiment provides, have the ingenious advantage of structure, and the cost of parts adopted is low, one-piece construction is less, and dirigibility is comparatively strong, is applicable to measuring at any time in process of production, significantly can saves production cost, increase work efficiency.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
