Description
Technical field
The utility model relates to the electronic stopper in tube shaped electric machine field, particularly a kind of tube shaped electric machine.
Background technology
Existing tube shaped electric machine often uses electronic stopper control stroke, but electronic stopper is due to its characteristic, the phenomenons such as chip internal program is stuck may occur, and in the time that the chip of electronic stopper is stuck, electronic stopper just can not play position-limiting action, and tube shaped electric machine continuous firing is likely brought danger.
Summary of the invention
The object that the utility model will reach is to provide a kind of electronic stopper of tube shaped electric machine, still can play position-limiting action in the time that electronic stopper chip internal program is stuck.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of electronic stopper of tube shaped electric machine, comprise base and mainboard, mainboard is electrically connected with motor, mainboard is arranged on base, also comprise speed change assembly, mainboard is provided with angular transducer and detects axle, angular transducer is electrically connected with mainboard, detecting axle is in transmission connection by the output shaft of speed change assembly and tube shaped electric machine, detecting shaft extension enters in angular transducer, detect axle and be provided with positive stop key along the distal end faces of the direction that stretches into angular transducer, in angular transducer, the position corresponding with positive stop key is provided with guide vane end stop, guide vane end stop both sides are provided with sensitive switch, detecting axle can rotate around the axis that detects axle in angular transducer, detecting axle can go to the sensitive switch of guide vane end stop one side tactile or tactile mutually with the sensitive switch of guide vane end stop opposite side mutually, sensitive switch is electrically connected with mainboard, when being touched, sensitive switch sends by mainboard the signal that makes motor stopping.
Detect axle with output shaft rotation, angular transducer record detect the rotational angle of axle and by data real time reaction to mainboard, the chip of mainboard is processed this output and is shown that whether motor should shut down, and correspondingly control motor.According to the model of tube shaped electric machine and use scenes, regulate the gearratio that detects axle and tube shaped electric machine output shaft by speed change assembly, making to detect axle rotational angle under normal circumstances in angular transducer is 0 °-300 °, at 0 °, when 300 ° of two positions, mainboard should send stopping signal, under these two states, detect the positive stop key of axle should be respectively with the sensitive switch of guide vane end stop both sides at a distance of approximately 20 °, do not touch mutually, in the time that the chip internal program of mainboard is stuck, make to detect axle and rotate the scope that may exceed 0 °-300 ° because not shutting down in time, if now mainboard can not be revised in time, the positive stop key that detects axle can touch in the sensitive switch of guide vane end stop both sides, after being triggered, sensitive switch makes motor stopping by mainboard, thereby guarantee safety.
Further, described speed change assembly comprises radius different some gears between two, and gear is coaxial and be fixed on and detect the part that axle exposes angular transducer with described detection axle, and the same time has and only have a gear to engage with output shaft.Change the gearratio that detects axle and output shaft by different gear ratios, rotate in setting range thereby guarantee to detect axle.
Adopt after technique scheme, the utlity model has following advantage:
In the time that mainboard chip internal program is stuck, make electronic stopper still can play position-limiting action by the sensitive switch on guide vane end stop and positive stop key.
