Abstract
The utility model discloses a stroke position limiter of door rolling machine which can solve problems that the present stroke position limiter of door rolling machine has complex structure and poor positioning accuracy. An inner gear ring (4) connects with a potentiometer (5) through a speed change mechanism (6), the potentiometer (5) connects with a drive motor through a control circuit. The stroke position limiter of door rolling machine has advantages of simple structure and accurate positioning.
Description
Affiliated technical field
The utility model relates to a kind of door-rolling machine, especially relates to a kind of door-rolling machine distance caging device of being made up of driven pulley and ring gear.
Background technology
At present, a kind of like this door-rolling machine distance caging device is disclosed on the market, its design feature is: by driven pulley, ring gear, idler gear, the profile of tooth drive link, left-handed screw mandrel, the dextrorotation screw mandrel, left-handed straight-tooth nut, dextrorotation straight-tooth nut, switch press plate, limit switch and governor motion are formed, ring gear is arranged in the driven pulley, idler gear and ring gear engagement, the profile of tooth drive link is connected with idler gear, left-handed screw mandrel, the dextrorotation screw mandrel is respectively by left-handed straight-tooth nut, dextrorotation straight-tooth nut and the engagement of profile of tooth drive link, at left-handed screw mandrel, one end of dextrorotation screw mandrel is provided with switch press plate, limit switch is installed on the housing of switch press plate direct of travel, at left-handed screw mandrel, the other end of dextrorotation screw mandrel is provided with governor motion. after adopting this structure, driven pulley is along with the door-hinge pipe rotates, the drive ring gear rotates, and then drive idler gear and the rotation of profile of tooth drive link, the profile of tooth drive link drives left-handed straight-tooth nut when rotating, dextrorotation straight-tooth nut rotates, two nuts are respectively along left-handed screw mandrel, the dextrorotation screw mandrel moves axially, when one of them nut arrives stroke limit point, pushing the limit switch contact by switch press plate makes drive motors cut off the power supply, thereby reach the effect of stroke limit. still, this structure is comparatively complicated, Installation and Debugging are inconvenience comparatively, and positioning accuracy is lower.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, door-rolling machine distance caging device that positioning accuracy is high.
For achieving the above object, the utility model door-rolling machine distance caging device is made up of driven pulley and ring gear, and ring gear is arranged in the driven pulley, and ring gear is connected with potentiometer by gear, and potentiometer is connected with drive motors by control circuit.
Gear is made up of duplicate gear, linkage gear, clamping plate and axle, duplicate gear is arranged between two clamping plate by axle, the gear wheel of duplicate gear and ring gear engagement, the pinion of duplicate gear and linkage gear engagement, linkage gear is connected with potentiometer by axle.
After adopting this structure, owing to be connected with potentiometer by linkage gear with the duplicate gear of ring gear engagement, thereby greatly simplify the structure; Because potentiometer is electrically connected with drive motors by control circuit, making door-rolling machine stroke positioning accuracy obtain bigger raising again, is desirable door-rolling machine distance caging device
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a door-rolling machine distance caging device master cross-sectional schematic of the present utility model.
Among the figure: 1. linkage gear 2. duplicate gears 3. driven pulleys 4. ring gears 5. potentiometers 6. gears 7. clamping plate
The specific embodiment
The door-rolling machine of the utility model shown in accompanying drawing distance caging device is made up of driven pulley 3 and ring gear 4, and ring gear 4 is arranged in the driven pulley 3, and ring gear 4 is connected with potentiometer 5 by gear 6, and potentiometer 5 is connected with drive motors by control circuit; Gear 6 is made up of duplicate gear 2, linkage gear 1, clamping plate 7 and axle, duplicate gear 2 is arranged between two clamping plate 7 by axle, the gear wheel of duplicate gear 2 and ring gear 4 engagements, the pinion of duplicate gear 2 and linkage gear 1 engagement, linkage gear 1 is connected with potentiometer 5. by axle
When the door-rolling machine distance caging device is in running order, driven pulley is along with the door-hinge pipe rotates, and the drive ring gear rotates, and then the linkage gear that drives duplicate gear and engagement therewith rotates, the linkage gear that rotates rotates by axle drive potentiometer, potentiometer is converted into the dielectric displacement signal with mechanical displacement signal, and signal is passed to control circuit by lead, by control circuit dependent instruction is passed to drive motors again.
