Description
Technical field
The utility model belongs to shaft Stroke Control field, more particularly to a kind of mechanical stroke controller.
Background technology
In machinery field, shaft is common part, some shafts as driving part, some shafts as transmission parts,
No matter being used as driving part or transmission parts, shaft is to work in a rotating manner.In some applications, such as
, it is necessary to control the positive warp number of turns of shaft, this just needs the stroke of countershaft to carry out for the folding and unfolding of curtain, folding and unfolding of electric mosquito net etc.
Control.At present, existing to be controlled generally by installation PLC on a drive, this there is following defect：PLC is installed on
It on driver, is connected between driver and shaft by transmission mechanism, this may be there are driving error, and control accuracy is low；Also
There is PLC to belong to circuit control, the reliability of circuit control is relatively low.
Utility model content
For overcome the deficiencies in the prior art and there are the problem of, the utility model provides a kind of mechanical stroke controller,
Control accuracy is high, and reliability is high.
The utility model is achieved through the following technical solutions：
A kind of mechanical stroke controller, including housing, the housing is equipped with and is connected with the rotating shaft screw, and screw is equipped with
With the screw hole sliding block of screw cooperation, housing is interior to be equipped with slide opening, and screw hole sliding block is located in slide opening, and housing is equipped with what is connected with slide opening
Sliding slot, screw hole sliding block are equipped with positioning region, and positioning region, by being extended in slide opening outside housing, and is slided by sliding slot along sliding slot, sliding
The both ends of slot are equipped with the /V testing agency for being right against positioning region.
The both ends of housing are run through at the both ends of the screw, and are rotatablely connected with the both ends of housing.
The /V testing agency includes microswitch, and microswitch is fixed on housing.
The cross section of the slide opening is square.
The /V testing agency is fixed on by adjustment seat on shell.
Screw is connected with shaft in the utility model, when shaft rotates screw is driven to rotate, and is driven in screw rotation process
Screw hole sliding block is slided along slide opening, when screw hole sliding block slides into predeterminated position, positioning region triggering /V testing agency, and /V detection
Mechanism sends control signal control associated mechanisms and shuts down, and so as to which shaft be controlled to stop rotating, control accuracy is high, and reliability is high.

Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below in conjunction with the drawings and specific embodiments into
One step is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of mechanical stroke controller, including housing 1, housing 1 is equipped with and is connected with shaft
Screw 2, screw 2 is equipped with the screw hole sliding block 3 coordinated with screw 2, slide opening 11 is equipped in housing 1, and screw hole sliding block 3 is located at slide opening
In 11, when screw 2 rotates screw hole sliding block 3 is driven to be slided in slide opening 11.Housing 1 is equipped with the sliding slot 12 connected with slide opening 11,
Screw hole sliding block 3 is equipped with positioning region 31, positioning region 31 by sliding slot 12 by being extended in slide opening 11 outside housing 1, and along sliding slot 12
It slides.The both ends of sliding slot 12 are equipped with the /V testing agency 4 for being right against positioning region 31, when positioning region 31 is moved to precalculated position
When, 31 top pressure /V testing agency 4 of positioning region sends stopping signal so as to trigger /V testing agency 4, and control shaft stops rotation
Turn.The cross section of slide opening 11 is square, this can effectively prevent screw rod sliding block 3 from being rotated with screw 2.
The both ends of housing 1 are run through at the both ends of screw 2, and are rotatablely connected with the both ends of housing 1.
/V testing agency 4 includes microswitch 41, and microswitch 41 is fixed on housing 1./V testing agency 4 passes through
Adjustment seat is fixed on housing 1, the position of adjustment seat adjustable limit testing agency 4, so as to the movable model of adjusting screw hole sliding block 3
It encloses, and then adjusts the rotating cycle of shaft.
The course of work of the present embodiment：When shaft rotates screw 2 is driven to rotate, 3 edge of screw hole sliding block is driven when screw 2 rotates
Slide opening 11 slides, and positioning region 31 is slided along sliding slot 12, the top pressure /V testing agency 4 when positioning region 31 is moved to precalculated position,
Send stopping signal so as to trigger /V testing agency 4, control shaft is stopped rotating, set due to /V testing agency 4 there are two,
Therefore the positive and negative rotation number of turns of shaft can be controlled.
Above-described embodiment is the preferable realization method of the utility model, is not the restriction to the utility model, not
Depart from the utility model inventive concept on the premise of, it is any it is obvious replacement the scope of protection of the utility model it
It is interior.
