Support ring, described support ring comprises: the annular disk of bottom and be connected to the body on described annular disk, described body is connected for dismantling with the bottom of Leeb Hardness Tester impact bar, and what described body can move up and down is arranged in the straight hole in described back-up block;
Spring, is set on described body, and described spring is between described annular disk and described straight hole.
Further, the number of described supporting leg is four.
Further, described straight hole is pilot hole, is provided with the locating slot that the described body of restriction overturns in described straight hole in described straight hole.
Further, described body is provided with the positioning bar that the shape with described locating slot matches.
Further, the Area of bearing forming between a plurality of described supporting legs is greater than the area of described annular disk.
Further, it is characterized in that, described body has the internal thread being connected with the bottom of Leeb Hardness Tester impact bar.
Further, described in each, the height of supporting leg is greater than the height of described body.
Further, described back-up block is cuboid.
Further, described in each, the height of supporting leg is 20 to 40mm, and the height of described body is 10mm.
Because supporting leg is supported on tested workpiece, by moving up and down of the body on support ring, the position that annular disk is passed through after movement is adjusted, and the test point position on the curved surface of total energy maintenance and various tested workpiece is tangent, guarantee the impact direction of test ball, improve measuring accuracy.For the curved surface of different curvature, the difference of the distance moving up and down that can be by body, the test point position of realizing on annular disk and different curve is tangent.

Drawing reference numeral explanation:
The bottom of 1 bracing frame 3 support ring 5 spring 7 Leeb Hardness Tester impact bar 11 supporting leg 111 feet 13 back-up block 131 straight hole 1310 locating slot 31 annular disk 33 body 330 positioning bar 70 Leeb Hardness Tester impact bars
Embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing explanation the utility model.
As shown in Figure 1, Leeb Hardness Tester curved surface supportive device comprises:
Bracing frame 1,
As shown in Figure 2, support frame as described above 1 comprises: a plurality of supporting legs 11, the back-up block 13 being connected with described supporting leg and be arranged on the straight hole 131 in described back-up block, each supporting leg 11 has a feet 111, and described back-up block 13 is positioned at the top of described feet 111; Supporting leg 11 is for controlling Leeb Hardness Tester support ring surface (annular disk 31) alignment curved surface tangent plane.As shown in Figure 2, the number of described supporting leg is for example four, and four feets 111 form rectangle, like this, supporting & stablizing, and symmetrical;
Further, as shown in Figure 2, described straight hole 131 is pilot hole, be for example circular port, in described straight hole, be provided with the locating slot 1310 that the described body 33 of restriction overturns in described straight hole, as shown in Figure 3, body 33 is for example the round tube of hollow, described body is provided with the positioning bar 330 that the shape with described locating slot matches, and body 33 does not rotate when guaranteeing to test, thereby guarantees the stability of test.
Further, as shown in Figure 1, the Area of bearing forming between a plurality of described supporting legs 11 is greater than the area of described annular disk 31, to annular disk 31 is formed to stable support.
Further, described body 33 has the internal thread being connected with the bottom 70 of Leeb Hardness Tester impact bar, like this, can form stable being connected with Leeb Hardness Tester impact bar 7, and be convenient to dismounting during test.
Further, described in each, the height of supporting leg 11 is greater than the height of described body 33, to annular disk 31 is contacted or concordant with testing curved surface.
