Abstract

The utility model relates to a novel step gauge. Locking modes, precision of cushion blocks and precision of measuring blocks of conventional step gauges all can impact on precision of the conventional step gauge; and the stability is not enough, dimension drift is very easy to generate, and later detection precision is affected. The novel step gauge comprises a base and a plurality of gauge blocks, the gauge blocks are directly fixed on the base, each gauge block comprises a main body portion and end portions, the main body portion is located at the middle of each gauge block and has a cylindrical shape, the end portions are located at two ends of each gauge block and is cone-shaped, and the main body portion has the same central axis with the end portions. The novel step gauge is simple in structure, convenient to use, free of the cushion blocks, washers and the like between the conventional measuring blocks; a locking structure is not used in connection; and defects of poor stability and the dimension drift of the conventional step gauges are overcome. The gauge blocks having cylindrical structures are easy to install; and users can easily select a measuring point of a measurement because the measuring point is the center of a cylinder, so a case that has measuring errors, which are generated because the measuring point is not easy to choose correctly when the measuring point of the conventional square measuring block is chosen, are prevented.

Description

Step gauge

Technical field

The utility model relates to a kind of step gauge.

Background technology

According to Its Relevant Technology Standards, the detecting error of coordinate measuring machine normally obtains according to the standard of known distance, the step gage that working standard has slip gauge and pieced together by slip gauge now.After traditional step gage is measured fast and the amalgamation of square cushion block by square, by certain locking mode, be locked on pedestal again, locking mode, cushion block precision and measure fast precision and all can exert an influence to the step gage precision, locking mode particularly, even when irrational locking mode dispatches from the factory, precision is accurate, along with the user uses, because stability is inadequate, be very easy to produce the size drift, the accuracy of detection after impact.

The utility model content

The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, provides a kind of structure simpler, stable step gauge.

For solving the problems of the technologies described above, this step gauge comprises pedestal and some gauge blocks, and described gauge block directly is fixed on pedestal, and in the middle of this gauge block comprises, cylindrical main part and two ends are the taper type end, the concentricity axle in described main part and end.

As optimization, described pedestal is provided with groove, and described gauge block all is arranged in this groove.

As optimization, described pedestal is equipped with isometrical through hole between any two gauge blocks.

This step gauge is simple in structure, easy to use, has omitted cushion block between the traditional measurement piece, pad etc., does not use locking mechanism to connect simultaneously, but directly is fixed on pedestal, has overcome traditional step gage poor stability, size drift.The gauge block of cylindrical structural is easy for installation, the center of circle that is simultaneously cylinder due to measurement point, measurement point during the easy State selective measurements of user, while having avoided traditional square measurement piece to select because of measurement point, easily the selection of generation measurement point is incorrect, and produces the situation of measuring error.

Below in conjunction with accompanying drawing, this step gauge is described further:

Fig. 1 is the perspective view (removal of part pedestal) of this step gauge;

Fig. 2 is the cross-sectional configuration schematic diagram of this step gauge.

Fig. 3 is the longitudinal plane structure schematic diagram of this step gauge.

In figure: 1-pedestal, 2-gauge block, 3-main part, 4-end, 5-groove, 6-through hole.

Embodiment

As Figure 1-3, this step gauge comprises pedestal 1 and some gauge blocks 2, and described gauge block 2 directly is fixed on pedestal 1, and in the middle of this gauge block 2 comprises, cylindrical main part 3 and two ends are taper type end 4, described main part 3 and the concentricity axle in end 4.Described pedestal 1 is provided with groove 5, and described gauge block 2 all is arranged in this groove 5.Described pedestal 1 is equipped with isometrical through hole 6 in 2, any two gauge block.
