Model utility content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, and the taper hole linkage structure for made up electrical equipment rack sheet metal part that a kind of assembly precision is high is provided.
In order to realize above object, a kind of taper hole linkage structure for made up electrical equipment rack sheet metal part that the utility model provides, comprise: link and the through hole that is arranged on the assembled position of sheet metal part, on described sheet metal part, the position of corresponding described through hole is provided with locating cones cylinder, the stub end of described locating cones cylinder is connected with the inwall of described through hole, and the internal diameter of the little head end of described locating cones cylinder matches with the external diameter of described link.Add locating cones cylinder by the position of corresponding described through hole on sheet metal part, and the accurate location that utilizes the self centering function of locating cones cylinder to realize adjacent two sheet metal parts, improved the assembly precision of electrical equipment rack; And, because described locating cones cylinder can be realized the location between adjacent two sheet metal parts automatically, thus time assembling, without the position regulating between adjacent two sheet metal parts, reduce assembling difficulty, time saving and energy saving.
In such scheme, described locating cones cylinder and described through hole are coaxially arranged.Like this, be convenient to the processing of this linkage structure, be also convenient to assembling.
In such scheme, the tapering α of described locating cones cylinder is 30～60 °, and in this angular range, the self-centering effect of described locating cones cylinder is best.
In such scheme, described locating cones cylinder and described sheet metal part are integral type structure.Certainly, also can adopt the mode of welding that described locating cones cylinder is welded on described sheet metal part.
In such scheme, described link is countersunk screw.
The utility model adds locating cones cylinder by the position of corresponding described through hole on sheet metal part, and the accurate location that utilizes the self centering function of locating cones cylinder to realize adjacent two sheet metal parts, has improved the assembly precision of electrical equipment rack; And, because described locating cones cylinder can be realized the location between adjacent two sheet metal parts automatically, thus time assembling, without the position regulating between adjacent two sheet metal parts, reduce assembling difficulty, time saving and energy saving.
The utility model is compared with the prior art, and fully shows that its superiority is: assembly precision is high and easy to assembly etc.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
As shown in Figure 1: the present embodiment provides a kind of taper hole linkage structure for made up electrical equipment rack sheet metal part, comprise: link 1 and the through hole 2 that is arranged on sheet metal part 4 assembled positions, on described sheet metal part 4, the position of corresponding described through hole 2 is provided with locating cones cylinder 3, the stub end of described locating cones cylinder 3 is connected with the inwall of described through hole 2, and the internal diameter of the little head end of described locating cones cylinder 3 matches with the external diameter of described link 1.Position by corresponding described through hole 2 on sheet metal part 4 adds locating cones cylinder 3, and the accurate location that utilizes the self centering function of locating cones cylinder 3 to realize adjacent two sheet metal parts 4, has improved the assembly precision of electrical equipment rack; And, because described locating cones cylinder 3 can be realized the location between adjacent two sheet metal parts 4 automatically, thus time assembling, without the position regulating between adjacent two sheet metal parts 4, reduce assembling difficulty, time saving and energy saving.
Above-mentioned locating cones cylinder 3 is coaxially arranged with described through hole 2.Like this, be convenient to the processing of this linkage structure, be also convenient to assembling.The tapering α of described locating cones cylinder 3 is 30～60 °, and in this angular range, the self-centering effect of described locating cones cylinder 3 is best.Described link 1 is countersunk screw.
Above-mentioned locating cones cylinder 3 is integral type structure with described sheet metal part 4.When actual production, first offer at the assembled position of described sheet metal part 4 circular hole matching with the external diameter of described link 1, then directly form described locating cones cylinder 3 at described circular hole place by stamping process.Certainly, also can adopt the mode of welding that described locating cones cylinder 3 is welded on described sheet metal part 4.
