Abstract
The utility model discloses a support for testing cover shape nut welding strength, wherein, a support block is arranged on the base of the support, which is perpendicular to the base; a thread column in a cantilever shape is arranged on the support block, which is perpendicular to the support block; the diameter of the thread column is corresponding to the aperture of a cover shape nut; the thread screwing length of the thread column is less than that of the cover shape nut. The utility model can fix the cover shape nut, which is used in a pressure tester for testing cover shape nut welding strength. By using the support, the welding strength of each cover shape nut can be tested so as to guarantee the welding quality of cover shape nuts.
Description
Technical field
The utility model is particularly related to a kind of support that is used to test the acorn nut weld strength.
Background technology
Motorcycle engine acorn nut in the past all adopts the method manufacturing of cold pier moulding, but the acorn nut cost that this method is made is higher, manufacture factory now for reducing the manufacturing cost of acorn nut, often adopt nut and lid independent processing and manufacturing respectively, and then be welded into an integral body, because acorn nut adopts welding manufacturing, so the gaseous tension of the generation of the weld strength of its weld must engine operation can be born the time, prevent the weld generation crack phenomenon that leaks air.Yet also be not specifically designed to the anchor clamps of test acorn nut weld strength at present, it can be tested by pressure testing machine, therefore, all be to adopt to take out the part trial assembly whether observed the acorn nut weld strength afterwards qualified for a long time, this detection mode can not detect the quality of each part product, the quality of product can not get guaranteeing, just pinpoints the problems after waiting installation, caused the waste of human and material resources.
Summary of the invention
The purpose of this utility model is, a kind of support that is used to test the acorn nut weld strength is provided, and it can be fixed acorn nut, is used for the weld strength of pressure testing machine test acorn nut weld.
The purpose of this utility model is achieved like this: a back-up block vertical with base is set on the base of this support, a threaded post that is cantilever is set on the back-up block, threaded post is vertical with back-up block, the diameter of threaded post is corresponding with the aperture of acorn nut, and the length of thread engagement of threaded post is less than the length of thread engagement of acorn nut.
Owing to adopted such scheme, a threaded post that is cantilever is set on the back-up block on the base of support, the diameter of threaded post is corresponding with the aperture of acorn nut, and the length of thread engagement of threaded post is less than the length of thread engagement of acorn nut.This support is fixed on the worktable of pressure testing machine, the acorn nut of need test is fixed on the threaded post by screw thread, because the length of thread engagement of threaded post is less than the length of thread engagement of acorn nut, therefore make the nut of acorn nut and the weld of lid not enter threaded post, be in overhead positions, exert pressure for the lid of acorn nut by pressure testing machine by predetermined force value, under the pressure of this force value, the crack does not appear in weld, the weld strength of then representing acorn nut reaches requirement, otherwise is defective.After the test acorn nut is screwed off from threaded post, promptly by checking and accepting.
The utility model is simple in structure, makes easily, and is easy to use, adopts it to test the weld strength of each part acorn nut, and the welding quality of acorn nut is guaranteed.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Embodiment
With reference to accompanying drawing, a back-up block vertical with base 2 is set on the base 1 of the utility model support, back-up block 2 is positioned at center, base 1 upper surface.Back-up block 2 adopts and is weldingly fixed on the base 1, perhaps is fastenedly connected on base 1 by screw also can reach effect same.Back-up block 2 is provided with a threaded post 3 that is cantilever near the position of upper end, and threaded post 3 is vertical with back-up block 2.Threaded post 3 is taked with the mode and the back-up block 2 of back-up block 2 whole machine-shapings as a whole, and to guarantee fastness, perhaps threaded post 3 adopts the mode of interference fit to be fixed on back-up block 2 also to reach effect same.The diameter of threaded post 3 is corresponding with the aperture of acorn nut 4, and the length of thread engagement of threaded post 3 is less than the length of thread engagement of acorn nut 4, and when making acorn nut be fixed on the threaded post 3, the weld of its nut and lid does not enter threaded post, is in overhead positions.Base 1 is provided with the installation via hole, makes the support can be by on the worktable that is bolted to pressure testing machine.
When the utility model is used to test the acorn nut weld strength, at first with support by on the worktable that is bolted to pressure testing machine, also can support be clamped on the worktable of pressure testing machine by other frocks; Then acorn nut is fixed on the threaded post of support by screw thread, makes the weld of nut and lid not enter threaded post, be in overhead positions; To the lid of the acorn nut F that exerts pressure, under the predetermined force value of pressure testing machine, the crack does not appear in the weld of nut and lid, represents that then the weld strength of acorn nut reaches requirement, is specification product, otherwise is defective by pressure testing machine.After the test acorn nut is screwed off from threaded post, promptly by checking and accepting.
