Abstract

A micron grade fine tuning structure of the utility model relates to a sphenoid fine tuning structure. The utility model composes a supporting plate, a supporting body, an upper sphenoid plate, a lower sphenoid plate, which is arranged in opposite to the upper sphenoid plate, and a micrometer. Wherein, a locating shaft is arranged on the underside of the supporting plate. A linear bearing is positioned between the supporting body and the locating shaft. The lower sphenoid plate is fixed to the supporting body, and the upper sphenoid plate is arranged between the supporting plate and the lower sphenoid plate. The micrometer, of which the contact is leaned against a stopper on the upper sphenoid plate, is positioned at the lower sphenoid plate. The upper and the lower sphenoid plates are provided with an extension spring in between. In the utility model, the slant movement of the upper sphenoid plate (traveling distance is represented as Y), caused by a rotating micrometer screw, is appeared as the horizontal movement of the upper sphenoid plate and the reciprocating of the table top (traveling distance is represented as X), according to Delta X=(X/Y)Delta Y. There, Delta Y is the stretching value of the micrometer swing arm and can be read directly, and Delta X is the height variance. When X/Y<0.1, for the precision of Delta Y is 0.01mm, the precision setting of over 0.001mm is available.

Embodiment

Below in conjunction with accompanying drawing, further describe the embodiment of micron order wedge shape fine tuning structure described in the utility model, but be not used for limiting protection domain of the present utility model.

As Fig. 1, Fig. 2 and shown in Figure 3, micron order wedge shape fine tuning structure described in the utility model comprises back up pad 1, supporter 4, last clapboard 5, following clapboard 6 and milscale 7.Wherein go up clapboard 5 and following clapboard 6 opposed, promptly go up the thicker end than clapboard 6 under the thin end correspondence of clapboard 5, thin end of clapboard 6 under the thicker end correspondence of last clapboard 5.Middle position is fixed with locating shaft 2 by attachment screw 10 below the described back up pad 1.Supporter 4 comprises circular bottom plate 41 and is positioned at the cylinder 42 of base plate 41 middle positions that cylinder 42 is sleeved on the locating shaft 2, and linear bearing 3 is installed between the two.Following clapboard 6 is fixed on the base plate 41 of supporter 4, has the hole of passing for cylinder 42 on it, has the slotted hole 51 that the cylinder 42 of confession supporter 4 moves on the last clapboard 5.On last clapboard 5, be fixed with block 8 and hang pin,, hang between the pin for two and be mounted with extension spring 9 also being provided with an extension pin on the clapboard 6 down.The shell of described milscale 7 is installed on the clapboard 6 by the fixed block 61 that is contained in down on the clapboard 6, and the contact 71 of milscale 7 is resisted against block 8 sides.Last clapboard 5 is installed between back up pad 1 and the following clapboard 6 by Sliding Structures.Described Sliding Structures can be two pairs of guide rail slide block pairs, promptly both sides are installed pair of guide rails I11, the slide block I12 that cooperates with described guide rail I11 more than a pair of or a pair of are installed on clapboard 6 down below last clapboard 5, pair of guide rails II13 is installed in both sides on last clapboard 5, the slide block II14 that more than installation on the back up pad 1 is a pair of or a pair of, cooperates with described guide rail II13, by these two pairs of guide rail slide block pairs, can realize the slippage of clapboard 5 between back up pad 1 and following clapboard 6.Last clapboard 5 also can be slidingly mounted between back up pad 1 and the following clapboard 6, as long as can realize relative motion by other Sliding Structures.The utility model is fixed together back up pad 1 and table top 15 in use.

As shown in Figure 4, principle of work of the present utility model is: because the effect of extension spring 9, the contact of milscale 7 withstands on (see figure 1) on the block 8 all the time.When the swing arm of turn milscale 7, because the constraint of guide rail I11 and slide block I12, last clapboard 5 will oblique movement (seeing Fig. 1, Fig. 2), this oblique movement is broken down into the tangential movement of guide rail II13 and moving up and down of slide block II14 again, because guide rail II14 and back up pad fix, and back up pad 1 is owing to the constraint of linear bearing 3 again, (see figure 3) can only move up and down, therefore, when the swing arm of turn milscale 7, the table top 15 of fixedlying connected with back up pad 1 will move up and down.As shown in Figure 4, according to formula: Δ X=(X/Y).ΔY。Δ Y is the stroke of milscale swing arm, can directly read, and Δ X is the variable quantity of height.When X/Y＜0.1,, can obtain the adjustment amount of the above precision of 0.001mm because the precision of Δ Y is 0.01mm.

More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that the utility model is protected.
