Description
Technical field
The utility model relates to a kind of stopping means, particularly relates to a kind of spacing dress of electric operator main drive gearPut.
Background technology
The main drive gear of electric operator refers to the screw-nut body being arranged in gear-box, and the nut of this mechanism is doneFor driving member is connected with the corner swing arm of executing agency. The leading screw of electric operator is also provided with torque sensor, works as biographyWhen moving nut contacts with arbitrary end limiting component, leading screw rotates and is obstructed, and the moment variations signal that torque sensor detects makes leading screwDriving mechanism stops driving.
In prior art, the stopping means of electric operator main drive gear is arranged on gear case body relevant positionStop screw. , stop screw is receiving that transmission nut can easy distortion or damage gear case body after clashing into repeatedly.
Summary of the invention
The utility model is for solving the problems of the technologies described above the stopping means that a kind of electric operator main drive gear is provided.
Technical solution adopted in the utility model is: a kind of stopping means of electric operator main drive gear, comprisesLeading screw in casing, casing and the transmission nut coordinating with threads of lead screw and the torque sensor of leading screw, described tank endsBe provided with limited block; Described limited block is provided with the lead screw hole of passing for described leading screw; On described lead screw hole periphery radiallyOutwards be provided with and hold hole tightly; The described bottom, hole of holding tightly is communicated to the end face of described limited block near described transmission nut by pushing away hole;Described holding tightly in hole is provided with and holds bar tightly, described in push away and in hole, be provided with push rod, described in hold bar tightly and connecting rod is passed through in described push rod endHinged; Described connecting rod described push rod to described push away hold tightly described in can promoting while moving in hole bar along described in hold hole tightly to describedDescribed leading screw is held in lead screw hole motion tightly. Pressure-ram after transmission nut moves to push rod place, push rod is pushed and is embraced by connecting rodTight bar, holds bar tightly and moves to lead screw hole along inclined hole under pressure, holds leading screw tightly, and the moment that torque sensor detects becomesChanging signal makes leading screw driving mechanism stop driving.
For fear of hold bar and leading screw friction tightly in the time not holding tightly, as further improvement, described in being exposed at, described push rod pushes awayEnd outside hole is provided with top board; Between described top board and described limited block, be provided with back-moving spring. At not pressure-ram of transmission nutTime, back-moving spring drives push rod to reset, and then is driven and held tightly bar reset by connecting rod, leaves leading screw.
As preferably, described top board surface is provided with rubber blanket, alleviates to hold tightly between bar and transmission nut to wear and tear.
As preferably, the hole of holding tightly on each described limited block is 8, is evenly distributed on around described lead screw hole.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, work as transmissionNut moves to pressure-ram behind push rod place, and push rod is pushed and held tightly bar by connecting rod, holds bar tightly under pressure along inclined holeTo lead screw hole motion, hold leading screw tightly, the moment variations signal that torque sensor detects makes leading screw driving mechanism stop driving.The utility model is simple in structure, not fragile, long service life.
The technical problem that solves except the utility model described above, form the technical characterictic of technical scheme and by thisOutside the advantage that the technical characterictic of a little technical schemes brings, other technologies problem, technology that the utility model can solveThe advantage that the other technologies feature comprising in scheme and these technical characterictics bring, will be hereinafter do by reference to the accompanying drawings intoThe explanation that one step is detailed.

Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinateAccompanying drawing is described in detail as follows:
As depicted in figs. 1 and 2, the present embodiment is a kind of stopping means of electric operator main drive gear, comprises caseLeading screw 3 in body 1, casing 1 and with the transmission nut 2 of leading screw 3 threaded engagement and the torque sensor (not shown) of leading screw,Transmission nut 2 is connected with the corner swing arm 4 of executing agency; Described casing 1 two ends are provided with limited block 5; Described limited block5 are provided with the lead screw hole of passing for described leading screw 3; On described lead screw hole periphery, being radially outwards evenly distributed with 8 embracesTieholen; The described bottom, hole of holding tightly is communicated to the end face of described limited block 5 near described transmission nut 2 by pushing away hole; DescribedHold tightly in hole and be provided with and hold bar 9 tightly, described in push away and in hole, be provided with push rod 7, described in hold tightly bar 9 with described push rod 7 ends by connectingBar 8 is hinged; Described hold tightly hole with described in push away link position place, hole and be provided with enough described link motions cavity; Described connecting rod 8Described push rod 7 to described push away hold tightly described in can promoting while moving in hole bar 9 along described in hold hole tightly and move to described lead screw holeHold described leading screw 3 tightly. The end pushing away outside hole described in described push rod 7 is exposed at is provided with top board 10; Described top board 10 surfaces are provided withRubber blanket 11, alleviates and holds wearing and tearing between bar and transmission nut 2 tightly; Between described top board 10 and described limited block 5, be provided with reset bulletSpring 6; At transmission nut 2, not when pressure-ram 7, back-moving spring 6 drives push rod 7 to reset, and then drives by connecting rod 8Hold bar 9 tightly and reset, leave leading screw 3.
The course of work of the present utility model is: pressure-ram after transmission nut moves to push rod place, push rod squeezes by connecting rodPressure is held bar tightly, holds bar tightly and moves to lead screw hole along inclined hole under pressure, holds leading screw tightly, the power that torque sensor detectsSquare variable signal makes leading screw driving mechanism stop driving. When transmission nut is not when pressure-ram, back-moving spring drives push rod multiplePosition, and then drive and hold bar reset tightly by connecting rod, leading screw left.
Above embodiment of the present utility model is had been described in detail, but described content is only better reality of the present utility modelExecute example, can not be considered to for limiting practical range of the present utility model. All do according to the utility model application range equalDeng variation and improvement etc., within all should still belonging to patent covering scope of the present utility model.
