Background

A thin part is used for being installed in a control part of electronic equipment, the structure of the thin part is shown in figures 1-2, the thin part comprises a thin plate 1 with the thickness of 0.5-1mm, a plurality of protrusions 2 are integrally formed on the bottom surface of the thin plate 1, and a plurality of convex hulls 3 with a certain height are formed on the top surface of the thin plate 1. After the thin part is produced and molded, a height gauge is required to be adopted to measure the height of each convex hull 3 in the process, if the measured height of one convex hull 3 is not in the design range, the thin part to be measured is judged to be an unqualified product, and the thin part to be measured is removed.

The method for measuring each convex hull on the thin part in the existing workshop comprises the following steps: the worker firstly puts the bulge 2 of the thin part flat on the detection platform, then the worker operates the height of the convex hulls 3 which are measured by the height gauge one by one, and then the height of each convex hull 3 on the first thin part is measured, and the operation is repeated, so that the residual thin part can be measured. However, although the method in use in a workshop still enables the height of each convex hull 3 on a thin part to be measured, the skilled person still presents the following technical drawbacks:

I. the size of the convex hull 3 is small, and the specific position of the convex hull 3 is difficult to observe visually through naked eyes, so that the time for a worker to search the position of the convex hull 3 is prolonged, all the convex hulls 3 on a thin part can be measured for a long time, and the measuring efficiency of the height of the convex hull is greatly reduced.

II. The sheet metal 1 of thin part is just unevenness itself, and its surface has slight deformation promptly to cause the high inaccuracy of the convex closure 3 of follow-up measurement, lead to before measuring at every turn, the workman will carry out the flattening to sheet metal 1, measures after the flattening again, and this has undoubtedly increased the process, and further increased the measuring time of convex closure, thereby further reduced the measurement of convex closure height efficiency. Therefore, a jig for greatly improving the efficiency of measuring the height of the convex hull is needed.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 3-4, a jig for measuring the height of a convex hull on a thin part comprises a base 4 and a cover plate 5, wherein the thickness of the base 4 is greater than that of the cover plate 5, a plurality of grooves 7 corresponding to the convex parts 2 on the thin part are further formed in the top surface of the base 4, the outline of each groove 6 is matched with the outline of the thin plate 1 of the thin part, the depth of each groove 6 is smaller than that of the thin plate 1, a plurality of grooves 7 corresponding to the convex parts 2 on the thin part are further formed in the bottom surface of each groove 6, the outline of each groove 7 is matched with the outline of each convex part 2, blind holes are formed in the left side and the right side of each groove 6 on the top surface of the base 4, magnets 8 are embedded in the blind holes, the magnets 8 are cylinders and are in interference fit with the blind holes, and two locating pins 9 arranged diagonally are further fixedly arranged on the top surface of the base 4.
