Abstract
The utility model discloses a straight-range electric executive mechanism which belongs to an industrial automatical device, in particular to a straight-range electric executive mechanism. The motor of the straight-range electric executive mechanism and a decelerator are coaxially arranged all together and arranged on a base. One end of a transmission shaft is connected with the decelerator, and the other end of the transmission shaft is connected with a screw rod. The screw rod is provided with a bearing frame engaged with the screw rod, a column with guiding rail is connected with the base, the guide groove of the bearing frame is arranged on the guiding rail, and the column is provided with a travel switch. The straight-range electric executive mechanism has the advantage of simple structure, large range, big load bearing, convenient installation and maintenance, and easy loading and unloading.
Description
Technical field
The utility model belongs to industrial automation arrangement, particularly straight stroke electric actuating mechanism.
Technical background
Traditional straight stroke electric actuating mechanism is subjected to the restriction of its structure because bearing frame is built-in, and stroke is all shorter, generally in 100mm; When process control need be carried out big Stroke Control, often adopt the principle of lever principle to realize, so not only be subjected to the restriction of steric requirements, and control precision is very poor, not easy to operate, this lever principle device has reduced the bearing capacity of actuator simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of big stroke straight stroke electric actuating mechanism, and it is simple in structure, and stroke range is big, and bearing capacity is big, is convenient to installation and maintenance, dismantles also very convenient.
Solving the scheme that technical problem of the present utility model adopts is: refill again on pedestal after motor and decelerator coaxial line are installed together, power transmission shaft one end connection reducer, other end connecting screw rod, bearing frame with its engagement is housed on the screw rod, connecting column on the pedestal with guide rail, the guide groove of bearing frame is contained in again on the guide rail simultaneously, and travel switch is housed on column.
Owing to adopted in this device worm drive to make the bearing frame motion, and bearing frame is subjected to the guiding and the location of guide rail, therefore only needs to increase the length of screw rod, bearing frame, column, just can increase stroke greatly, and the motor of smaller power just can drive heavier load.When the bigger carrying of needs, as long as change more powerful motor or reduce screw speed.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented successively among the figure: motor 1, decelerator 2, key 3, up-thrust bearing 4, lower thrust-bearing 5, power transmission shaft 6, pin 7, screw rod 8, bearing frame 9, lower bound range switch 10, base 11, suspension ring 12, column 13, upper limit travel switch 14, footstock 15, lower bearing sleeve 16, upper bearing sleeve 17, casing 18.
Embodiment
Referring to Fig. 1, the motor 1 of this mechanism is contained on the decelerator 2, motor 1 output shaft is connected in line with decelerator 2 power shafts, the mount pad of decelerator 2 is loaded on the upper bearing sleeve 17, upper bearing sleeve 17 and lower bearing sleeve 16 are by being bolted on the footstock 15, up-thrust bearing 4 is installed in upper bearing sleeve 17 and the lower bearing sleeve 16 in opposite directions with lower thrust-bearing 5, two thrust bearings 4, dress power transmission shaft 6 in the middle of 5, and there is step that two bearings is separated in the middle of the power transmission shaft 6, the output shaft of decelerator 2 is connected by part 3 with power transmission shaft 6, downward power is born by lower thrust-bearing 5, and the power that makes progress is born by up-thrust bearing 4, make this mechanism can adapt to two-way load, two thrust bearings are also being born radial load.Be connected with the column 13 of a pair of band guide rail below footstock 15, its lower end is equipped with base 11 again, thereby footstock 15, column 13 and base 11 have formed firm supporting frame.Bearing frame 9 is housed on the guide rail of column 13, power transmission shaft 6 usefulness pins 7 are connecting screw rod 8, threaded engagement on the screw thread of screw rod 8 and the bearing frame 9, when motor 1 motion, driving screw rod 8 rotates, bearing frame 9 is moved up and down along the guide rail of column 13, and will rotatablely move has become rectilinear motion, and not limited by stroke distances.Lower bound range switch 10 and upper limit travel switch 14 are housed on the column 13 of this mechanism, can limit the stroke of actuator, play a protective role; The thread of screw rod 8 adopts trapezoidal, can improve bearing capacity, and increases the reliability of using; Bearing frame 9 is T-shaped, lower end band one hollow tube, and the hollow tube bottom is equipped with suspension ring 12, can change easily, adapts to different load installation requirements; Casing 18 is housed on footstock 15, can disassembles as required, be convenient to the motor of wiring or replacing different capacity, and simultaneously motor and decelerator played a protective role.
The utlity model has following good effect and advantage: use very extensive, as the control of gate valve, The frequent lifting of weight etc.; Can with the forming control systems such as computer, controller, existing local operation function, Also has long-range switching control function; Fill up do not have on the market big stroke, the straight stroke electric of big bearing capacity holds The blank of row mechanism, its stroke range can reach 1000mm, and maximum hoist capacity can reach 20000 newton; Be convenient to Installation and maintenance is dismantled also very convenient.
