Abstract
The utility model discloses a kind of folding control mechanism based on half-nut, comprise a housing, two symmetrical 1/2 half-nuts are installed in housing, two 1/2 half-nuts all have through hole, polished rod is through through hole, and polished rod two ends are fixed on two sidewalls of housing, between the left side wall of housing and 1/2 left half-nut, spring is installed, also spring is installed between the right side wall of housing and right 1/2 half-nut, described spring is placed on polished rod, track groove is had between two described 1/2 half-nuts, track groove is built-in with rotating cam, described rotating cam ovalize.The beneficial effect that the utility model plays is: this device adopts half-nut, polished rod and spring mechanism can realize the closed of two 1/2 half-nuts, and the camming movement that rotates between two 1/2 half-nuts to the position of specifying time, just can by two 1/2 half-nut foldings again.
Description
Technical field
The utility model relates to a kind of folding control mechanism, particularly relates to a kind of folding control mechanism based on half-nut.
Background technique
Nut is mainly used on some clamping tools with the transmission that coordinates of leading screw, such as bench vice, numerical control machine tool etc.What general transmission major part was used now is that full nut matches with leading screw, and under the rotation of handle or the driving of electric power, full nut lead agency moves on leading screw, and such transmission is comparatively slow, and the time of needs is long, is unfavorable for increasing work efficiency.
Summary of the invention
For above-mentioned prior art problem, the utility model provides a kind of folding control mechanism based on half-nut, and construction is simple, and control folding speed fast, working efficiency is high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of folding control mechanism based on half-nut, comprise a housing, two symmetrical 1/2 half-nuts are installed in housing, two 1/2 half-nuts all have through hole, polished rod is through through hole, and polished rod two ends are fixed on two sidewalls of housing, between the left side wall of housing and left 1/2 half-nut, spring is installed, also spring is installed between the right side wall of housing and right 1/2 half-nut, described spring is placed on polished rod, track groove is had between two described 1/2 half-nuts, track groove is built-in with rotating cam, described rotating cam ovalize.
Described rotating cam is connected with a connecting rod, and the other end of connecting rod is fixed with control rotating disk.
The beneficial effect that the utility model plays is: this device adopts half-nut, polished rod and spring mechanism can realize the closed of two 1/2 half-nuts, and the camming movement that rotates between two 1/2 half-nuts to the position of specifying time, just can by two 1/2 half-nut foldings again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural drawing of half-nut and rotating cam.
In figure: 1, housing, 2, right 1/2 half-nut, 3, left 1/2 half-nut, 4, polished rod, 5, spring, 6, track groove summit, 7, track groove, 8, rotating cam, 9, track groove concave point.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of folding control mechanism based on half-nut of the utility model, comprises a housing 1, and be provided with the symmetrical right side 1/2 half-nut 2 and left 1/2 half-nut 3 in housing 1, right 1/2 half-nut 2 and left 1/2 half-nut 3 can form a complete half-nut.
Two 1/2 half-nuts all have through hole, polished rod 4 is through through hole, and polished rod 4 two ends are fixed on two sidewalls of housing 1, between the left side wall of housing 1 and left 1/2 half-nut 3, spring 5 is installed, between the right side 1/2 sidewall of housing 1 and right 1/2 half-nut 2, spring 5 is also installed, two described springs 5 are placed on polished rod 4, track groove 7 is had between two described 1/2 half-nuts, track groove 7 is built-in with rotating cam 8, rotating cam 8 is rotated in track groove 7, described rotating cam 7 ovalize.Track groove about 7 two-end-point is track groove summit 6, track groove about 7 two-end-point is track groove concave point 9, distance between two track groove summits 6 is greater than the distance between two track groove concave points 9, when making rotating cam 7 forward track groove concave point 9 to like this, right 1/2 half-nut 2 and left 1/2 half-nut 3 are open mode, when rotating cam 7 forward to track groove forward two track groove summits to time, right 1/2 half-nut 2 of spring-compressed and left 1/2 half-nut 3, make right 1/2 half-nut 2 and left 1/2 half-nut 3 be closed state.
As shown in Figure 2, in order to rotate rotating cam 8 more easily, rotating cam 8 is connected with a connecting rod, and the other end of connecting rod is fixed with and controls rotating disk 10.Only needs rotation control rotating disk 10 just can complete the opening and closing to right 1/2 half-nut 2 and left 1/2 half-nut 3.
