Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1 and 2, fig. 1 is a schematic structural diagram of a paint film measuring device for a columnar part, fig. 2 is a pencil hardness tester, and the device provided by the embodiment includes an auxiliary tool and a pencil hardness tester 5; the pencil hardness tester is arranged on the auxiliary tool and used for measuring the hardness and the thickness of a paint film of a part to be measured, which is arranged in the auxiliary tool.

Fig. 3 is an auxiliary tool, which comprises a base 1, a baffle 2, a screw 3, a guide rail and a V-shaped groove;

set up V type groove on base 1, the column part 4 that awaits measuring set up in the V type groove, V type groove top is provided with the guide rail, base (1) position rectangle strip, the rectangular limit setting of rectangle strip is followed in V type groove, V type groove opening terminal surface sets up the step respectively to the outside both sides, then sets up the guide rail on the step, pencil hardness appearance 5 set up in on the guide rail to when being suitable for pencil hardness appearance 5 in order to be suitable for moving on the guide rail, realize leaving the mar to pencil 6 in pencil hardness appearance centering on the part that awaits measuring, the guide rail is in be provided with baffle 2 that is used for preventing 6 hardness appearance roll-off guide rails of pencil on the both ends face on base 1, baffle 2 passes through screw 3 to be fixed on the terminal surface of the guide rail of base 1.

The width of the guide rail provided by the embodiment is slightly larger than that of the pencil hardness tester, so that the pencil hardness tester does not have clamping stagnation and the like during front-and-back movement, a V-shaped groove is arranged below the central symmetrical position of the guide rail and used for placing a part to be tested, and the V-shaped design can be suitable for testing the part with a larger diameter range and can prevent the part from moving back and forth; both ends are equipped with the screw hole around the base for the installation baffle prevents that pencil hardness appearance roll-off guide rail from leading to the circumstances such as damage.
