It statesThe bottom at shape both ends respectively from the workpiece be measured different planes be in contact, the measurement top plate with it is described
It clamps to be equipped between backing plate and limits the limiting device for measuring top plate amount of movement in the horizontal direction.
As an implementation, the limiting device includes that limited post and setting clamp backing plate or outer layer backing plate described
On U-type groove, limited post is mounted on the side for measuring top plate, and the limited post matches with the U-type groove.
As an implementation, corner block is additionally provided on the measurement top plate, the corner block is right angled triangle,
Its right-angle side and the right-angle side of the inflection point for measuring top plate match.
As an implementation, the bottom surface for measuring top plate is inclined-plane, quilt on the angle of inclination on the inclined-plane and measured workpiece
The setting angle for measuring plane is consistent, and the backing plate that clamps is equipped with the inclined-plane branch consistent with measured workpiece setting angle
Support, so that the top surface for measuring top plate is parallel to horizontal plane.
As an implementation, it is equipped with chamfering along the top edge for measuring top plate.The outer layer backing plate with it is described
It clamps and bolt is installed with fixation between backing plate.
The advantageous effect that the utility model is reached is：It devises a set of convenient for the flat of measurement inclination class rod piece difference plane
The measurement cubing of row degree, structure detection can obtain rapidly measurement result, for parallel between the inclined-plane of different planes on brace
Error spatially is converted to 2 points in plane of error using the conversion of device itself by the measurement of degree, high certainty of measurement,
Difficulty is low.

Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figs. 1-5, the utility model provide it is a kind of measurement rod piece difference plane between the depth of parallelism measurement cubing, including
It clamps backing plate 1, outer layer backing plate and measures top plate 2, clamp backing plate 1, outer layer backing plate and measure the composition workpiece accommodating cavity of top plate 2,
So that being in the cavity by workpiece, the both sides of workpiece accommodating cavity are installed respectively clamps backing plate 1, outer layer backing plate, accommodating cavity
Top be measure top plate 2, measure top plate 2 beShape,The bottom at shape both ends respectively on workpiece be measured difference
