Abstract
The utility model discloses a back-and-forth rotary mechanism of pharmaceutical equipment; the mechanism comprises a box body (8) and a rotary frame (10); a lead screw (1) is rotationally arranged on the box body (8); the rotary frame (10) is connected onto the lead screw (1); a nut (5) is meshed and sleeved on the lead screw (1); a reset spring (4) is arranged between the nut (5) and the box body (8); and a shifting fork (6) which is transmitted and butted with the nut (5) is slidably arranged on the box body (8). The utility model is the back-and-forth rotary mechanism of the pharmaceutical equipment with simple structure, low manufacturing cost and stable performance.
Description
Technical field
The utility model relates to a kind of round rotating machinery, particularly relates to a kind of round rotating machinery of pharmaceutical equipment.
Background technique
At pharmaceutical industry, medicine bottle need come and go in process of production and rotatablely move.The round apparatus structure that rotatablely moves of realizing medicine bottle at present is complicated, and manufacture cost is high, and performance is unstable.
The model utility content
The utility model technical problem to be solved provides a kind of simple in structure, low cost of manufacture, the round rotating machinery of the pharmaceutical equipment of stable performance.
In order to solve the problems of the technologies described above; The round rotating machinery of the pharmaceutical equipment that the utility model provides comprises casing and swivel mount, and screw mandrel is rotatably installed on the described casing; Described swivel mount is connected on the described screw mandrel; Engagement is set with nut on described screw mandrel, between described nut and described casing, is provided with return spring, and on described casing, sliding is provided with the shift fork that docks with described nut transmission.
Described shift fork adopts roller slip to be installed on the described casing.
Described screw mandrel adopts sliding sleeve and circlip to be rotatably installed on the described casing.
Described return spring is enclosed within described screw mandrel and is between described nut and the described casing.
Described shift fork is provided with roller away from the other end that docks with described nut transmission.
Adopt the round rotating machinery of the pharmaceutical equipment of technique scheme, when horizontal force action during in roller, shift fork drives nut and does the straight line horizontal motion, because circlip has limited the degrees of freedom of the Horizontal displacement of screw mandrel, screw mandrel can only rotate.After reaching the stroke that needs, the horizontal force that acts on roller is eliminated, and relies on return spring to do reverse promotion nut and retreats, and nut drives the screw mandrel counterrotating, realizes that the horizontal motion of screw mandrel and swivel mount changes crankmotion into.Under the fixed situation of pitch, change the displacement distance of nut, can change the back and forth angle of rotation of screw mandrel.The utility model includes only screw mandrel, shift fork and return spring, and is simple in structure, low cost of manufacture, stable performance.
In sum, the utility model is a kind of simple in structure, low cost of manufacture, the round rotating machinery of the pharmaceutical equipment of stable performance.
Description of drawings
Fig. 1 is the utility model structural representation plan view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Referring to Fig. 1; Screw mandrel 1 adopts sliding sleeve 3 and circlip 2 to be rotatably installed on the casing 8, and swivel mount 10 is connected on the screw mandrel 1, and engagement is set with nut 5 on screw mandrel 1; Return spring 4 is enclosed within and is on the screw mandrel 1 between nut 5 and the casing 8; Shift fork 6 adopts roller 7 to be slidingly mounted on the casing 8, and shift fork 6 one ends dock with nut 5 transmissions, and the other end is provided with roller 9.
Referring to Fig. 1, when horizontal force action during in roller 9, shift fork 6 drives nuts 5 and does the straight line horizontal motion, because circlip 2 has limited the degrees of freedom of the Horizontal displacement of screw mandrel 1, screw mandrel 1 can only rotate.After reaching the stroke that needs, the horizontal force that acts on roller 9 is eliminated, and relies on return spring 4 to do reverse promotion nut 5 and retreats, and nut 5 drives screw mandrel 1 counterrotating, realizes that the horizontal motion of screw mandrel 1 and swivel mount 10 changes crankmotion into.Under the fixed situation of pitch, change the displacement distance of nut 5, can change the back and forth angle of rotation of screw mandrel 1.
