Abstract
The utility model discloses a zero point positioner of a stepping motor, comprising a stepping motor and a stepping motor driver, and also comprising a casing located at one side of the output shaft of the stepping motor and forming a sealed space with the stepping motor, wherein the output shaft of the stepping motor is connected with a transmission shaft rotating along with the output shaft, the sealed space of the casing is provided with a code disc sleeved on the transmission shaft, a grooved optical coupler is arranged near the rotating passing position of the code disc in the casing, such that when the gap of the code disc passes through the grooved optical coupler, the receiving end of the grooved optical coupler receives a light signal, producing a low level, otherwise producing a high level. Therefore the output shaft of the stepping motor can fast and conveniently find the zero point position, and further rotates to any angle position from the zero point position under the cooperation of the stepping motor driver. The zero point positioner has the advantages of simple structure and convenience in operation.
Description
Technical field
The utility model relates to a kind of mechanical movement positioner, particularly relates to a kind of stepping motor zero-point positioning device.
Background technology
Along with the continuous development of modern industry, the zero-point positioning technology has obtained extensive use, for example rotary encoder; The zero-point positioning technology is just contained in portion within it, and rotary encoder is because its volume is little, and precision is high; Life-span is long, and is easy for installation, and interface shape is abundant; Advantages such as reasonable price at home and abroad are used widely many years ago, but propose higher protection requirement to using under open air and the adverse circumstances.There is not at present a kind of stepping motor positioner that provides zero-point positioning to adapt to adverse circumstances again on the market.
Because the defective that above-mentioned existing stepping motor positioner exists, the design people actively studies innovation, in the hope of founding a kind of stepping motor zero-point positioning device of new structure, makes it have more practicality.
The utility model content
The main purpose of the utility model is, overcomes the defective that existing stepping motor positioner exists, and a kind of stepping motor zero-point positioning device of new structure is provided; Technical problem to be solved is to make the stepping motor output shaft can carry out zero-point positioning rapidly easily; And it is under the cooperation of stepper motor driver, rotate at any angle on the position, and simple in structure, with low cost, easy for installation by dead-center position; Thereby be suitable for practicality more, and have the value on the industry.
The purpose of the utility model and solve its technical problem and adopt following technical scheme to realize.A kind of stepping motor zero-point positioning device according to the utility model proposition; Comprise stepping motor and stepper motor driver; On the output shaft of stepping motor, be connected with power transmission shaft with its rotation; Also comprise a side of the output shaft that is positioned at stepping motor and form the housing of seal cavity with stepping motor; In the seal cavity of said housing, be provided with the code-disc that is sleeved on the said power transmission shaft, the sealed environment through dark stops the interference of extraneous light to the flute profile optocoupler, in housing, is provided with the flute profile optocoupler near the position of said code-disc rotation process.
Aforesaid stepping motor zero-point positioning device, wherein, the overlap of said code-disc is provided with breach, and said flute profile optocoupler is transferred to stepper motor driver with the signal that the breach on the said code-disc passes through.
By technique scheme, the utility model stepping motor zero-point positioning device has advantage at least:
Near being employed in the position of said code-disc rotation process in the housing flute profile optocoupler is set, when the breach of code-disc during through the flute profile optocoupler, flute profile optocoupler receiving terminal receives light signal; Produce low level; Otherwise the generation high level makes the stepping motor output shaft can find dead-center position rapidly easily in this way, and then under the cooperation of stepper motor driver; Rotate at any angle on the position by dead-center position, have simple in structure, easy to operate advantage.
In sum, the stepping motor zero-point positioning device of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
Description of drawings

Fig. 2 is the fundamental diagram of the described stepping motor zero-point positioning of the utility model device.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the embodiment of the utility model specify as after.
As depicted in figs. 1 and 2; A kind of stepping motor zero-point positioning device; Comprise stepping motor 1, stepper motor driver 7, housing 2, power transmission shaft 3, code-disc 4 and flute profile optocoupler 5; On the output shaft 6 of stepping motor, be set with power transmission shaft with its rotation; Housing 2 be positioned at stepping motor output shaft 6 a side and form seal cavity with stepping motor 1, be provided with the code-disc 4 that is sleeved on the power transmission shaft 3 in the seal cavity of housing 2, code-disc 4 is provided with flute profile optocoupler 5 near rotating the position of processes housing 2 in.The overlap of code-disc 4 is provided with breach, and the signal that flute profile optocoupler 5 passes through the breach on the code-disc 4 is transferred to stepper motor driver 7.
The course of work of the utility model is: in normal operation, and to the stepping motor energising, when code-disc is followed in the stepping motor rotating process; Make its rotation; Observe flute profile optocoupler output level, when the breach on the code-disc passes through flute profile optocoupler 5, flute profile optocoupler 5 receiving terminal receiving optical signals; Produce low level; Otherwise then produce high level, flute profile optocoupler 5 is transferred to stepper motor driver 7 with low level signal, and stepper motor driver 7 confirms that according to the signal of feedback stepping motor is at dead-center position at this moment.After finding dead-center position, stepper motor driver 7 is given stepping motor 1 through sending different pulse quantity, and then drive stepping motor 1 is rotated at any angle on the position by dead-center position.
The above; It only is the preferred embodiment of the utility model; Not being that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment exposure as above, yet is not in order to limit the utility model; Anyly be familiar with the professional and technical personnel; In not breaking away from the utility model technical scheme scope, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents of above-mentioned announcement capable of using, be the content that does not break away from the utility model technical scheme in every case;, all still belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
