Abstract
The utility model discloses a portable planeness tester comprising a supporting plane, and a scale fixed on the supporting plane, wherein one side of the supporting plane is provided with a handle, and the other side thereof is provided with three reference rods distributed equiangularly; the ends of the three reference rods are positioned on the same plane; and after reaching across the supporting plane, the measuring end of the scale is positioned on the plane. When in specific implementation, the reference rods are three bolts rotatably fixed on the supporting plane. On the basis that the testing accuracy is fully considered, the portable planeness tester aims at being portable and simple, and the scale is used for testing by utilizing the reference plane formed by the three reference rods distributed equiangularly, thus being capable of conveniently testing the planeness of a workpiece to be tested.
Description
[technical field]
The utility model belongs to a kind of portable planarity checking instrument.
[background technology]
In the machine tooling operation, the mensuration of workpiece planarization degree not only influences the crudy of product itself, also is directly connected to the precision of utilizing the various device instrument that this workpiece is made.At present, a kind of bikini flatness detecting instrument that detects the annular workpiece is arranged, its structure comprises disk, contact, transverse bearing and indicating gauge.Uniform three radial bar holes on the disk, be equipped with the contact of link supporting in each bar hole, each contact touches mutually with the end face of measured workpiece, show by the indicating gauge that is fixed on the disk, its design feature is, be equipped with rotating eccentric wheel in the hole of bar hole, other two Kong Zhongjun are equipped with in addition that be equipped with on elastic support, each elastic support can be along the transverse bearing of disk radial expansion, and eccentric wheel touches mutually with the cylindrical of each transverse bearing with measured workpiece.Use it can detect the flatness of annular workpiece entire working surface.The problem that the bikini flatness detecting instrument of this structure exists is: not only complex structure, cost height, and carry inconvenience, be not suitable for the mensuration of workpiece planarization degree.
[summary of the invention]
For overcoming the prior art above shortcomings, the utility model aims to provide a kind of portable planarity checking instrument, and this check meter has check flatness precision height, easy to carry and advantage of simple structure.
For achieving the above object, the utility model has adopted following technical scheme: this portable planarity checking instrument, comprise a supporting plane, be fixed on the scale on the described supporting plane, it is characterized in that: the one side of described supporting plane is provided with handle, the another side of supporting plane is provided with three and is the baseline rod that isosceles triangle distributes, and three baseline rod end points are positioned on the plane; After the measuring junction of described scale extends through supporting plane, in the same plane with three baseline rod end points.
Aforesaid portable planarity checking instrument, when specifically implementing, described baseline rod is three and revolves and put the bolt that is fixed on the supporting plane.
Beneficial effect: compared with prior art, the utility model is taking into full account on the basis of testing accuracy, base oneself upon portable, simple and easy, utilize three to be the formed reference plane of baseline rod end points that isosceles triangle distributes, by scale check the 4th whether with described reference plane place at grade, thereby can check out the 4th error amount with reference plane easily, and finish check the whole work-piece surface.
[description of drawings]
Fig. 1 is the perspective view of an embodiment of the utility model.
Among the figure: supporting plane 1, face 11, screw 12, bayonet socket screw 13, bayonet socket 14; Handle 2; Scale 3, sounding rod 31, measuring junction 32; Baseline rod 4, baseline rod end points 41.
[embodiment]
Referring to Fig. 1.Scale 3 and handle 2 are positioned on the one side 11 of supporting plane 1, and baseline rod 4 can adopt bolt arrangement, revolve from lower to upper to put in the screw 12 of supporting plane 1.Three baseline rods 4 are isosceles triangle and distribute, near two baseline rods 4 of scale 3 to another root distance from equating that they are positioned at the another side of supporting plane 1.Three baseline rod end points 41 can form a reference plane by adjusting, grinding.Scale 3 is through bayonet socket 14, is fixed on the front end of supporting plane 1 by securing member by bayonet socket screw 13, and sounding rod 31 is the global facility of scale 3, after its measuring junction 32 extends through supporting plane 1, also is positioned on the described reference plane, and the pointer of scale 3 is made zero.For guaranteeing that in whole checkout procedure measuring junction 32 can be pressed on the surface of the workpiece of surveying all the time, measuring junction 32 should skip over reference plane a bit.
During use, hand-held this check meter is mobile on the surface of surveys workpiece, for example: at the abrasive surface of workpiece or scratch on the face mobilely, according to shown pointer value on scale 3 dial plates, can check out the flatness of measured workpiece easily, whether belong to true plane.
Claims (2)
