Abstract
The invention provides a connection method for different kinds of metal. The connection method includes that one end of one kind of the metal is machined into a circular-shaft shape, and a plurality of blind holes are drilled in a machined circular shaft surface and distributed around the machined circular shaft axis evenly; an inner hole is machined in one end of another kind of the metal and is in clearance fit with the a previous machined shaft in size, a plurality of through hole are drilled in the outer wall of the inner hole of a part and are identical to the blind holes drilled in the circular shaft in size, and the through holes are evenly distributed around the inner hole axis; the machined circular shaft of the first metal is inserted into the machined inner hole of the other metal, so that the through holes in the outer wall of the inner hole coincide with the blind holes in the circular shaft; thermo-curing type epoxy resin adhesives are filled in the hole and put into an oven to enable the epoxy resin adhesives to be cured. The connection method is simple and convenient in production processing, wide in application and significantly high in connection performance.
Description
Technical field
The present invention relates to a kind of connecting means of dissimilar metals
Background technique
The mechanical connection method of metal current and metal is welded to connect conventionally, is threaded and is connected with interference.Welding has different requirements to different metal materials, is connected with stainless as copper, adopts welding just very difficult.Be threaded and adopt, because the direction of screw thread is unidirectional, therefore for oppositely, the shearing force that it can bear is smaller, even if add screw thread glue, effect is also bad.Adopt interference to connect for the size requirement coordinating higher, and the expanding force that different metal material produces in the time of mutual close-fitting is also different, versatility is not strong.Adopt chemical bonding, traditional mode is that axle is processed in one end of metal, another kind of metal one end processing pore-forming, and fastening glue is coated in two part cooperation places, is more mutually assembled together.Because glue is in Yu Zhou gap, hole, axle coordinates too the solid glue of degree of tightness may be inoperative with hole, coordinate and too tightly glue all can be squeezed out again, and fastening glue mainly relies on the viscous force of glue and metal surface, higher to metal surface requirement, applicability is wideless.
Summary of the invention
The invention provides a kind of connecting means of dissimilar metals, its objective is and solve the shortcoming that prior art scheme exists, make its processing and installation simple, connect reliable.
The method that the present invention adopts is: circular shaft type is processed in one end of a kind of metal, bores several blind holes on this processing circular shaft surface, and these several blind holes become uniform arrangement around processing circular shaft line.Another metal one end processes an endoporus, and this hole dimension coordinates with the size gap of machining shaft above, bores several through holes at this inner bore of part outer wall, the consistent size of the blind hole of boring on the size of through hole and circular shaft, and these several through holes become uniform arrangement around interior axially bored line.The processing circular shaft of one metal is inserted in the processing endoporus of another metal, several through holes of endoporus outer wall are overlapped with the blind hole on circular shaft.In hole, fill thermosetting epoxy resin adhesive, put into baking oven and make epoxy resins adhesive curing.
The usefulness of this patent of invention be two metals radial and axial be all subject to fixing.Tensile force and shearing force only depend on the performance of epoxy resin glue itself, and irrelevant with the adhesive force of finished surface and epoxy resins glue, performance significantly improves, and the method production technology is easy, is widely used.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is processing circular shaft metalwork schematic diagram;
Fig. 2 is processing endoporus metalwork schematic diagram;
Fig. 3 is assembling schematic diagram;
Embodiment
As shown in Figure 1, metal 1 is processed one section of circular shaft 11, and in the several blind holes 12 of circular shaft surface Machining, these several blind holes 22 become uniform arrangement as shown in Figure 2 around the axis of processing circular shaft 11, and metal 2 is processed endoporus 21, and endoporus 21 is coordinated with the size gap of circular shaft 11.Bore several through holes 22 at endoporus 21 outer walls, these several through holes 22 are around the uniform arrangement of axis of endoporus 21, as shown in Figure 3, the circular shaft 11 of metal 1 injects 21 li of the endoporus of metal 2, several endoporus 12 of metal 1 and several endoporus 22 of metal 2 are overlapped. in several holes 12 and hole 22, fill thermosetting epoxy resin adhesive, put into baking oven and make epoxy resins adhesive curing.
