In order to achieve the above purpose, the technical scheme of the utility model is that:

a flatness rapid detection jig comprises a bottom plate, a plurality of positioning columns and two measuring blocks, wherein the positioning columns and the two measuring blocks are arranged on the bottom plate;

each positioning column is arranged on the bottom plate, and the height of the positioning column protruding out of the bottom plate is greater than the heights of the two gauge blocks;

the height difference of the two gauge blocks is a preset value.

Furthermore, each positioning column is a hollow column.

Furthermore, each positioning column comprises a large hole and a small hole, the small hole is close to the bottom plate, and the large hole is formed in the end portion, far away from the bottom plate, of the positioning column.

Further, the large holes are communicated with the small holes.

Furthermore, the bottom plate is provided with a groove, and the end part of the positioning column is embedded in the groove and is in interference fit with the groove.

Furthermore, every reference column all includes body and rib, the outer wall body of body is located to the rib, the rib inlays in the recess.

Further, the length direction of rib with the central axis parallel arrangement of body, the length of rib is less than the degree of depth of recess.

The utility model has the advantages that: through setting up bottom plate, a plurality of reference column and two gauge blocks of difference in height at the default within range, realize the purpose of short-term test work piece surface flatness, improve production efficiency and detect the qualification rate.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.

Referring to fig. 1 to 4, a flatness rapid detection fixture of the present invention includes a bottom plate 1, a plurality of positioning columns 2 disposed on the bottom plate 1, and two gauge blocks 3;

each positioning column 2 is arranged on the bottom plate 1, and the height of the positioning column 2 protruding out of the bottom plate 1 is greater than the heights of the two gauge blocks 3;

the height difference between the two gauge blocks 3 is a preset value.

Specifically, in the embodiment, the number of the positioning columns 2 is four, four positioning columns 2 are respectively fixed on the same side of the bottom plate 1 through bolt connectors, the heights of the four positioning columns 2 protruding out of the surface of the bottom plate 1 are the same, the height difference of two gauge blocks 3 is set to be 0.4mm, the workpiece 100 is firstly turned over and fixed on the four positioning columns 2, the distance between the workpiece 100 and the surface of the bottom plate 1 is equal to the heights of the two gauge blocks 3, firstly, one gauge block 3 is placed between the workpiece 100 and the bottom plate 1, the gauge block 3 moves along the edge of the workpiece 100 and smoothly passes through, then another gauge block 3 is placed between the workpiece 100 and the bottom plate 1 and moves along the edge of the workpiece 100, the two gauge blocks 3 both pass smoothly to indicate that the surface flatness of the workpiece 100 is within 0.4mm, which is satisfactory, and the other gauge block 3 cannot pass smoothly to indicate that the surface flatness of the workpiece 100 is unqualified.

Through setting up bottom plate 1, a plurality of reference column 2 and two differences in height gauge blocks 3 at the default within range, realize the purpose of short-term test work piece surface flatness, improve production efficiency and detect the qualification rate.

Every reference column 2 is hollow post, and the setting of hollow post structure reduces the area of the terminal surface precision of polishing of reference column 2, reduction in production cost.

Every reference column 2 all includes macropore 21 and aperture 22, aperture 22 is close to the setting of bottom plate 1, macropore 21 is located reference column 2 and is kept away from the tip of bottom plate 1, and the setting of aperture 22 facilitates the use bolted connection spare to fix reference column 2 on bottom plate 1, and the setting of macropore 21 further reduces the area with the 100 contact surfaces of work piece, reduces the area of the terminal surface precision of polishing of reference column 2, reduction in production cost.

The big holes 21 are communicated with the small holes 22, so that the processing is easy, and the processing difficulty is reduced.

The bottom plate 1 is equipped with the recess, the tip of reference column 2 inlays in the recess and with recess interference fit, conveniently firmly fixes reference column 2 on bottom plate 1.

Every reference column 2 all includes body 23 and rib 24, the outer wall body of body 23 is located to rib 24, rib 24 inlays in the recess, and the setting of rib 24 increases the frictional force of reference column 2 and recess, improves the accurate nature that detects.

The length direction of the ribs 24 is parallel to the central axis of the body 23, and the length of the ribs 24 is smaller than the depth of the grooves.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
