Abstract
The utility model discloses a bridge plate capable of measuring the straightness of a vertical plane. The bridge plate comprises a bridge plate for measurement. A threaded hole is arranged on the position where a side face of the long side of the bridge plate is corresponding to two supporting anchors. The bridge plate further comprises two leaning blocks with a sliding hole. A butterfly-shaped bolt passes through the sliding hole of the leaning block and is connected with the threaded hole of the bridge plate with a thread, thus the leaning block is fixed. The bridge plate provided by the utility model not only can measure the straightness and the flatness of a horizontal plane, but also is convenient for measuring the straightness of the vertical plane, and has the advantages of simple structure and easy operation.
Description
Technical field
The utility model relates to the bridge plate of a kind of Linearity Measurement, flatness, but especially a kind of bridge plate of measuring vertical face linearity.
Background technology
Bridge plate is one of important tool of Linearity Measurement, flatness, and common adjustable bridge plate can produce different spans, above behind the placement catoptron; Straight line moves on flat board; Emit beam to catoptron through autocollimator, be received again after reflection, just can read the dull and stereotyped height relief volume of going up each point; And then calculate dull and stereotyped linearity, flatness, this is conventional measuring method.But this method can not be used to measure the linearity that is positioned at vertical plane, like the linearity of dull and stereotyped groove, machine tool guideway vertical plane.
Summary of the invention
But the purpose of the utility model provides a kind of bridge plate of measuring vertical face linearity, can effectively solve the problem that vertical plane can't Linearity Measurement.
The purpose of the utility model realizes as follows: but the bridge plate of this measuring vertical face linearity; Comprise measuring bridge plate; Corresponding two support lower margin places are provided with threaded hole in one side, long limit of bridge plate; Two pieces that lean on that have slide opening are arranged in addition, have wing bolt to pass slide opening by piece through fixing by piece on the threaded hole that is threaded in bridge plate.Leaning on slide opening on the piece to be used for regulating and lean on elongation under the piece, to measure the groove of the different depths, is to improve measuring accuracy, leans on the surface of contact of piece should reconditioning smooth, and makes chamfered.During measuring vertical face linearity, make two to lean on piece to move bridge plate near measured vertical plane all the time, the vertical plane that measures is risen and fallen is delivered to autocollimator through the catoptron of placing on the bridge plate, and the horizontal component of reading after the reception in the relief volume gets final product.When the level measurement, can unclamp wing bolt and will lean on to move on the piece and be higher than the bridge plate lower margin.
The utility model not only can be measured linearity, the flatness of surface level, and is convenient for measuring the linearity of vertical plane, and is simple in structure, easily operation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1-bridge plate 2-wing bolt 3-leans on piece.
Embodiment
With reference to Fig. 1; The utility model comprises measuring bridge plate 1; Corresponding two are supported the lower margin places threaded hole are set in one side, long limit of bridge plate 1, have in addition two have a slide opening lean on piece 3, have wing bolt 2 to pass slide opening by piece 3 through leaning on piece 3 fixing on the threaded hole that is threaded in bridge plate 1.
Claims (1)
