Compared with the prior art, the utility model, designed the structure that mechanical dimensional change amplifies detection mechanism, utilized lever mechanism of amplification principle, amplified micro - size through appropriate lever, made micro - size detected out easily by conventional sensor.
Description
Technical field
The utility model relates to field of mechanical technique, the amplification detection mechanism of specifically a kind of mechanical dimension change.
Background technology
In automobile back door hinge, there is a kind of very thin semicircle copper bush.Because its thickness only has about 1mm usually, adopt conventional proximity transducer to be difficult to detect, and adopt its cost performance of other special sensors not high, also poor by reliability after various factors.
Therefore, need to design a kind of can amplification the change of mechanical microscale dimensions, thus conventional proximity transducer can be utilized to carry out the special mechanism detected.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of can amplification the change of mechanical microscale dimensions, thus conventional proximity transducer can be utilized to carry out the special mechanism detected.
In order to achieve the above object, the utility model is the amplification detection mechanism of a kind of mechanical dimension change, comprise guide pin bushing, guide pillar, worktable panel, balancing weight, lever, proximity transducer and bearing, it is characterized in that: one end of worktable panel is set in outside the upper end of guide pin bushing, bearing is provided with bottom the other end of worktable panel, the lower surface of bearing is provided with groove, the outside surface of bearing is provided with proximity transducer, guide pillar is provided with in guide pin bushing, the bottom of guide pillar is connected with the hinged support of lever one end, fulcrum is adopted to be connected between lever with guide pin bushing, lever is provided with balancing weight, the other end of lever is positioned at the groove of bearing.
The top planes of described guide pin bushing and the top planes of described guide pillar are in same level.
Described fulcrum is positioned at the one end near guide pillar on lever.
The utility model compared with the existing technology, devises the structure of change amplification detection mechanism of mechanical dimension, utilizes lever amplifying mechanism principle, by microscale dimensions by suitable lever amplification, microscale dimensions is detected easily by conventional sensors.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is the G-G cut-open view of the utility model Fig. 3.
See Fig. 1-Fig. 3,1 is guide pin bushing; 2 is guide pillar; 3 is worktable panel; 4 is balancing weight; 5 is lever; 6 is fulcrum; 7 is hinged support; 8 is proximity transducer; 9 is bearing.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 1-Fig. 3, the utility model is the amplification detection mechanism of a kind of mechanical dimension change, comprises guide pin bushing, guide pillar, worktable panel, balancing weight, lever, proximity transducer and bearing.One end of worktable panel 3 is set in outside the upper end of guide pin bushing 1, bearing 9 is provided with bottom the other end of worktable panel 3, the lower surface of bearing 9 is provided with groove, the outside surface of bearing 9 is provided with proximity transducer 8, be provided with guide pillar 2 in guide pin bushing 1, the bottom of guide pillar 2 is connected with the hinged support 7 of lever 5 one end, adopts fulcrum 6 to be connected between lever 5 with guide pin bushing 1, lever 5 is provided with balancing weight 4, and the other end of lever 5 is positioned at the groove of bearing 9.
In the utility model, the top planes of guide pin bushing 1 and the top planes of guide pillar 2 are in same level.When not detecting workpiece, guide pillar 2 can not be stressed, when having detection workpiece, and guide pillar 2. under the gravity pressure of detection workpiece
Fulcrum 6 is positioned at the one end near guide pillar 2 on lever 5, and guide pillar 2 presses down 1 millimeter, and the other end of lever 5 upwarps 5 millimeters, thus is exaggerated variable quantity.
The deadweight of guide pillar 2 is balanced by the balancing weight 4 on lever 5.
The utility model operationally, the detection workpiece of small thickness size will be had, as semicircle copper bush, be placed on the top of guide pillar 2, utilize the deadweight detecting workpiece to be pressed down by guide pillar 2, thus drive one end of lever 5 to press down, under the effect of fulcrum 6, the other end of lever 5 tilts and swings in the groove of bearing 9, and proximity transducer 8 is lit.
The utility model is not when detecting workpiece, and by the impact of balancing weight 4, guide pillar 2 is forever upper, and proximity transducer 8 is in extinguishing waiting status.
