Description
Technical field
The utility model relates to a kind of anti-down mechanism, is specifically related to the anti-down mechanism of a kind of straight line, belongs to field of mechanical technique.
Background technology
In existing technology, the application of anti-down mechanism is very extensive, the especially anti-down mechanism of straight line, all needs to adopt the anti-down mechanism of straight line to carry out spacing to it during many work pieces process.But when spaces compact time, as only porose in workpiece and hole is very little, or under not having the situations such as boss, the anti-down mechanism of traditional straight line just cannot use in compact space.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of anti-down mechanism.
According to the technical scheme that the utility model provides, anti-down mechanism, comprises stand, stand is fixedly connected with mounting blocks, between stand and mounting blocks, is provided with trimmer, in mounting blocks, have a through main aperture, anti-down bar is arranged in the main aperture of mounting blocks, and mounting blocks upper end is provided with end cap;
Described mounting blocks both sides also have two side openings be communicated with main aperture; Carry out spacing by the first holding screw and dog screw to anti-down bar in one of them side opening; Be provided with elastic mechanism in another side opening, elastic mechanism contacts with anti-down bar.
Described elastic mechanism comprises the second holding screw, steel ball and spring; Steel ball props up anti-down bar, is provided with spring between the second holding screw and steel ball.
The side of described anti-down bar offers a chute, and dog screw can move up and down in chute.The opposite side of described anti-down bar has two detents along the axis of anti-down bar, and the steel ball in elastic mechanism can enter in detent.
Described anti-down masthead end arranges handle ball.
The beneficial effects of the utility model: the utility model is simple and reliable for structure, safe and reliable; One hand can operate, and degree of tightness is adjustable; Be applicable to the place of aperture and some spaces compact.

Detailed description of the invention
As schemed, 1 shows: anti-down mechanism, comprises stand 1, stand 1 is fixedly connected with mounting blocks 5, trimmer 2 is provided with between stand 1 and mounting blocks 5, have a through main aperture in mounting blocks 5, anti-down bar 3 is arranged in the main aperture of mounting blocks 5, and mounting blocks 5 upper end is provided with end cap 4;
Described mounting blocks 5 both sides also have two side openings be communicated with main aperture; Carry out spacing by the first holding screw 6 and dog screw 8 to anti-down bar 3 in one of them side opening; Be provided with elastic mechanism in another side opening, elastic mechanism contacts with anti-down bar 3.
Described elastic mechanism comprises the second holding screw 9, steel ball 11 and spring 10; Steel ball 11 props up between anti-down bar 3, second holding screw 9 and steel ball 11 and is provided with spring 10.
The side of described anti-down bar 3 offers a chute, and dog screw 8 can move up and down in chute.
The opposite side of described anti-down bar 3 has two detents along the axis of anti-down bar 3, and the steel ball 11 in elastic mechanism can enter in detent.
Described anti-down bar 3 top arranges handle ball 7.
Have two operating positions during utility model works, namely unclamp with anti-down, on anti-down bar 3, corresponding two operating positions are respectively provided with a detent.
In the utility model, stand 1 is the mounting platform of anti-down mechanism, and trimmer 2 can adjust anti-down bar 3 and the spacing of workpiece, adapts to the workpiece of uncertain surplus; The anti-down bar 3 driven by handle 7 is moved up and down and realizes the anti-down of workpiece; End cap 4 can carry out spacing, in the main aperture preventing foreign material from entering on mounting blocks 5 to anti-down bar 3; First holding screw 6 and dog screw 8 can form double nuts structure thus loosen; Former and later two second holding screws 9 pairs of springs 10 carry out spacing.
When mechanism is unclamped, anti-down bar 3 is extracted by handle ball 7, workpiece hole is exited in anti-down bar 3 front end, a detent of anti-down bar 3 is corresponding with steel ball 11, steel ball 11 withstands in the position of detent by the spring force of spring 10, thus prevent the landing of anti-down bar 3, now end cap 4 blocks the shaft shoulder, and double nut mechanism withstands on chute one end and ensures anti-down bar 3 non rotating.Spring force suffered by steel ball 11 is adjustable locks.
When mechanism is in anti-down state, slightly enforcing handle ball 7 makes anti-down bar 3 advance, until anti-down bar 3 front end puts in workpiece hole, steel ball 11 is pushed out detent along the conical surface, when steel ball 11 runs into rear side apex point, steel ball 11 is rapidly by the detent of jacking back, and namely operating position puts in place.Now, fast 5 end face gears are installed on the shaft shoulder.
When this mechanism arrives two operating positions, hand can feel slight vibrations, is applicable to the anti-down of aperture and compacted location.
