Abstract
The utility model relates to a flexible positioning device for a step motor, which comprises a step motor and a rack, a round disc, a photoelectric sensor and a computer. On the disk, a notch is provided. The disk is fixed on the shaft of the step motor. On the rack, near the point where the notch of the disk rotates passing, the photoelectric sensor is fixed. The photoelectric sensor sends the signal when the notch of the disk passes to the computer, which outputs pulse signals to the step motor. Such a positioning way that a disk with a notch is fixed on the shaft of the step motor and a photoelectric sensor and a computer are provided allows the positioning device to be simple and of low cost, and to achieve flexible and accurate positioning at different locations. By closed-loop controlling of the motor through the notch, such technical problems as loss of step and accumulated errors, etc. can be eliminated when the step motor operates at high speed.
Description
Affiliated technical field
The utility model belongs to the mechanical movement positioner, particularly relates to a kind of stepping motor flexible positioning device.
Background technology
Present known stepping motor exists in the re-positioning device lose the technical problem in step and to adopt in order to solve at work, is mostly to adopt photoelectric sensor is arranged to be positioned near the stepper motor driven mechanical parts running orbit.Photoelectric sensor will be installed to realize the location in two fixed positions at movement locus two ends respectively for the fixing situation of a kind of movement locus length like this; If being driven mechanical parts running orbit length needs under the situation of multiple different length, when the control step motor positions in a plurality of positions, a plurality of photoelectric sensors just need be set at the diverse location of corresponding multiple different length finish the location, so not only complicated in mechanical structure has also increased cost.
The utility model content
The utility model provides a kind of location flexible for solving the technical problem that exists in the known technology, can be at the stepping motor flexible positioning device of multiposition location.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes stepping motor and frame, also includes disk, photoelectric sensor and a computer; On described disk, gap is arranged, described disk is fixed on the axle of described stepping motor, near the above the position of gap rotation process of disk of frame, be fixed with a photoelectric sensor, signal input computer when described photoelectric sensor passes through the gap on the described disk, the computer output pulse signal is given stepping motor.
The utility model can also adopt following technical measures:
Described computer can be single-chip microcomputer, industrial control computer or PLC.
Advantage and the good effect that the utlity model has are: owing to adopt this locate mode of fixing the disk of a band gap and a photoelectric sensor and computer being arranged on step motor shaft, not only positioning device structure is simple, cost is low, and can be implemented in diverse location flexibly, accurate location, form Closed-Loop Control of Stepping Motor by the gap position, lose the technical problem of the error of step and generation accumulation in the time of also can eliminating the stepping motor high speed operation.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplifies now and following the present invention is used for embodiment on the integrated test bench for creepage breaker, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, stepping motor A is coaxial the connection with leading screw D, and integrated test bench for creepage breaker operating breaker handle carries out the slide block B and the leading screw D engagement of on/off switch, has the dish C that 1 about 80mm of diameter has a trapezoidal gap on the stepping motor A.Disk C is fixed on the stepping motor A axle; Photoelectric sensor F is fixed on the back-up block of the support leading screw D the disk C gap rotational trajectory near.The back-up block of stepping motor A, support leading screw D is fixed on the frame plate E.
As shown in Figure 2, photoelectric sensor F will receive the digital quantity input port that the high level signal that produces when disk C goes up gap by its conducting light paths is sent into industrial control computer, and the signal that industrial control computer is exported given umber of pulse and rotation direction pulse by the digital quantity output port is given stepping motor A.
The utility model had both included in the foregoing description: be fixed on stepping motor A, stepping motor A on the frame plate go up the fixing disk C that has gap, near disk C gap rotational trajectory the photoelectric sensor F of indirect securement on frame plate, and be used for receiving the industrial control computer of the signal of photoelectric sensor F high level signal and the given umber of pulse of output and rotation direction pulse to stepping motor A.
Its course of work is: follow in the stepping motor rotation process at disk, most of the time is the light path that stops photoelectric sensor F, when the disk gap turns to when making photoelectric sensor F conducting light paths, thereby connect the digital quantity input port that circuit signal is sent to industrial computer.The every conducting of photoelectric sensor once like this, for when a gap arranged on disk C, promptly be that stepping motor A leading screw D rotates a week (if m gap arranged on the disk C, then disk C revolution moves 1/m week, photoelectric sensor F conducting once, the every conducting of photoelectric sensor is only stepping motor A leading screw D for m time and rotates a week like this), industrial computer is by programmed counting once.For the number of times of the then corresponding different disk C gap in different positions through photoelectric sensor F conducting, i.e. industrial computer counts.Industrial computer is by rotation direction and the umber of pulse of two digital quantity output ports difference control step motor A, when the industrial computer counts with after set point is consistent, industrial computer stops the pulse input of digital quantity output port to stepping motor A, and then stepping motor A stops at setting position.Thereby realize the accurate and flexible location.Successively control step motor A positions under the different multiple situation of mechanical parts running orbit length to being driven when needs, then can by give put that different set point industrial control computers is counted the number of times of disk C gap process and with the set point of needs relatively, realize stepping motor A is reached the accurate location of diverse location.
