Description
Technical field
The utility model relates to a kind of man-operated mechanism of straight travel pneumatic actuating mechanism, is mainly used in straight travel pneumatic actuating mechanism manually-operable needs.
Background technique
At present, the man-operated mechanism of the straight travel pneumatic actuating mechanism that we commonly use is screw rod A, spiral shell core B structure, to get on the bus long screw at screw rod, elongated spiral shell core is arranged in the long screw of screw rod, as shown in Figure 2, when stroke is longer, spiral shell core is longer, corresponding, the long screw of getting on the bus at screw rod is longer, brings difficulty but also increase cost of production not only to the processing of part; Assembling is complicated, and bumpy motion is smooth and easy.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides the man-operated mechanism of straight travel pneumatic actuating mechanism, screw rod is adopted as solid screw, eliminate spiral shell core, the company's of adding nut, this mechanism, structure is simple, cost is low, stable movement, cunning are fast, thus improve the working life of man-operated mechanism, ensure that the high quality of pneumatic actuator.
The utility model for achieving the above object, the technological scheme adopted is: a kind of man-operated mechanism of straight travel pneumatic actuating mechanism, comprise: piston rod, screw rod, it is characterized in that: also comprise and connect nut, steel ball, Cock screw, described screw rod is solid screw, the shaft of screw rod one end is provided with a circle groove I, above groove I, the screw rod the other end is provided with a guiding groove along the Vertical direction of shaft, the described hole wall connecting one end in nut bore is provided with a circle groove II, the hole wall connecting the other end in nut bore is provided with one section of screw thread, screw is provided with outside company's nut, screw communicates with groove II, described one end connecting nut is inserted on screw rod, the groove II connecting nut is corresponding with the groove I of screw rod, several described steel ball is arranged in groove II and groove I by screw, described Cock screw and screw are screwed together, connect nut rotatable on screw rod by several steel ball, described piston rod is screwed together with the other end connecting nut.
The beneficial effects of the utility model are: the man-operated mechanism of straight travel pneumatic actuating mechanism of our development, eliminates elongated spiral shell core part, and avoid and to get on the bus elongated screw at screw rod, processing is simple, reject rate is low, has saved processing cost; In groove II and groove I, loading multiple steel ball, that man-operated mechanism is assembled is simple, smooth and easy, hand behaviour movement process steady slide block, extends man-operated mechanism working life, ensure that the high quality of pneumatic actuator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the man-operated mechanism of prior art.
