Description
Technical field
The utility model relates to a kind of aluminium alloys to increase seat screw thread nested structure, belong to technical field of transformer manufacturing.
Background technique
To reduce cost, copper sheet usage amount is reduced, the product process-cycle is shortened, guarantees product quality, heavy-duty generator
Transformer is existing using the high-strength aluminum alloy with low magnetic property.Bushing shell for transformer, which increases seat ring flange threaded hole with aluminium alloy, to be made
It is connected with, but aluminium alloy flange disk intensity is low, is easily damaged.
Utility model content
The purpose of the utility model is to provide a kind of aluminium alloys to increase seat screw thread nested structure, and assembling is quick, guarantees casing peace
Intensity is filled, aluminium alloy flange disk is less likely to be damaged, and solves the above problem existing for background technique.
The technical solution of the utility model is:
A kind of aluminium alloy raising seat screw thread nested structure increases seat, aluminium alloy flange, screw thread comprising connection bolt, aluminium alloy
Hole, stainless steel thread bush and stop pin, the interior matching of the threaded hole of the aluminium alloy flange are equipped with stainless steel thread bush, stainless steel spiral shell
The upper end outer wall of line set is equipped with semi-circular groove one, and the upper end hole wall of threaded hole is equipped with semi-circular groove two, one He of semi-circular groove
The matching setting of semi-circular groove two, forms mounting groove, and stop pin is arranged in mounting groove, and connection bolt passes through aluminium alloy flange screw thread
Aluminium alloy flange is fixed on aluminium alloy and increased on the side wall of seat by the stainless steel thread bush in hole.
Two semi-circular grooves one are symmetrically arranged on the upper end outer wall of the stainless steel thread bush, on the upper end hole wall of threaded hole
Two semi-circular grooves two are symmetrically arranged with, two matching settings of semi-circular groove one and two semi-circular groove two form two mounting grooves,
Stop pin is two, is separately positioned in two mounting grooves.
For the threaded hole installation strength for guaranteeing aluminium alloy flange, after aluminium alloy raising seat completes, the aluminium of connecting sleeve
The threaded hole opening diameter of alloy flange is greater than the connection diameter of bolt.The thread bush of insertion be stainless steel material, internal side diameter be with
The internal screw thread that connection bolt matches, outside diameter is the external screw thread to match with aluminium alloy flange threaded hole.In threaded hole and not
The stainless steel stop pin of anti-rotation, such as pin are added between rust steel thread bush.
The good effect of the utility model: assembling is quick, meets bushing shell for transformer installation requirement, and structure novel guarantees set
Pipe installation strength, aluminium alloy flange disk are less likely to be damaged.
Detailed description of the invention
Fig. 1 is the utility model mounting structure schematic diagram；
Fig. 2 is the portion Fig. 1 I structural schematic diagram；
Fig. 3 is the utility model aluminium alloy flange threaded hole schematic diagram；
Fig. 4 is the utility model structure diagram；
In figure: aluminium alloy increases seat 1, aluminium alloy flange 2, threaded hole 3, stainless steel thread bush 4, stop pin 5.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples:
A kind of aluminium alloy raising seat screw thread nested structure increases seat 1, aluminium alloy flange 2, spiral shell comprising connection bolt, aluminium alloy
Pit 3, stainless steel thread bush 4 and stop pin 5, the interior matching of the threaded hole 3 of the aluminium alloy flange 2 are equipped with stainless steel thread bush 4,
The upper end outer wall of stainless steel thread bush 4 is equipped with semi-circular groove one, and the upper end hole wall of threaded hole 3 is equipped with semi-circular groove two, partly
Circular trough one and the matching setting of semi-circular groove two, form mounting groove, and stop pin 5 is arranged in mounting groove, and connection bolt passes through aluminium
Aluminium alloy flange 2 is fixed on aluminium alloy and increased on the side wall of seat 1 by the stainless steel thread bush 4 in 2 threaded hole 3 of alloy flange.
Two semi-circular grooves one, the upper end hole wall of threaded hole 3 are symmetrically arranged on the upper end outer wall of the stainless steel thread bush 4
On be symmetrically arranged with two semi-circular grooves two, two matching settings of semi-circular groove one and two semi-circular grooves two form two installations
Slot, stop pin 5 are two, are separately positioned in two mounting grooves.
The utility model lies in that providing a kind of aluminium alloy raising seat screw thread nested structure, guarantee casing installation strength, aluminium alloy
Stainless steel thread bush is added in all threaded holes of flange and increases stop pin.It is this to be able to satisfy bushing shell for transformer installation requirement,
Structure novel, technological innovation.
