Description
Technical field
The utility model relates to a kind of commutator fields, and in particular to a kind of commutation piece fixed structure of Novel commutator.
Background technique
Hooked reverser generally by commutator base and commutator base outer circle make circumference arrangement copper segment
(i.e. commutator segment) composition, the essential structure of copper segment are as follows: including main leaf body and set on the hook of main leaf body medial surface, changing
When forming to device, main leaf body is implanted into commutator base with commutator base firm connection together by hook, and traditional changes
Pass through the first inserted sheet being arranged on hook foot to piece and main leaf body is plugged in far from the second inserted sheet that the first inserted sheet is oppositely arranged and changes
Molding first inserted sheet not only forms difficulty height on device matrix, but directly on hook foot, and wastes material, specific manifestation are as follows:
If wanting to form the first inserted sheet on hook foot, the outer circle by hook foot is needed to be enlarged to not a half a millimeter, otherwise the first inserted sheet can not lead to
Extrusion forming is crossed, and needs very big squeeze pressure, and often results in Service Life of Extrusion Mold contracting when squeeze pressure is excessive
Short or direct damage, not only high production cost, and technology difficulty is big, raw materials consumption is big, therefore is badly in need of providing a kind of manufacture hardly possible
Spend low, raw materials consumption is few and the commutation piece fixed structure of high production efficiency is connect with commutator base.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art,
A kind of commutation piece fixed structure of Novel commutator is provided.
To achieve the above object, the utility model provides following technical solution: a kind of commutator segment of Novel commutator is solid
Determine structure, include multiple commutator segments that commutator base and circular commutator base are circumferentially arranged, the commutator segment includes
Main leaf body and the hook foot for being set to main leaf body one end, it is characterised in that: be equipped with and hook foot protrusion direction one in the middle part of the main leaf body
The first inserted sheet caused, the commutator base are equipped with the first connected slot compatible with the first inserted sheet.
By adopting the above technical scheme, traditional commutator segment be required to by hook foot outer circle increase with it is to be extruded when formed with hook foot
The contrary inserted sheet of hook portion, and it is not only excessive and production difficulty is larger in hook foot part waste material in this way, by
Extrusion forming is needed in inserted sheet, and often results in Service Life of Extrusion Mold when squeeze pressure is excessive and shortens or directly damage,
Production cost is improved, and the utility model uses setting and consistent first inserted sheet of hook foot protrusion direction in the middle part of main leaf body, leads to
It crosses the first inserted sheet and is plugged in commutator base and be arranged in the first connected slot compatible with the first inserted sheet, abandoned traditional
The mode that inserted sheet is connect with commutator base again is squeezed on hook foot, reduces production difficulty and saves the use of the material at hook foot
Amount.
A kind of commutation piece fixed structure of above-mentioned Novel commutator can be further arranged to: the main leaf body is oppositely arranged
The other end of hook foot one end is equipped with the second inserted sheet that or direction first inserted sheet vertical with main leaf body is obliquely installed, the commutator base
Body is equipped with the second connected slot compatible with the second inserted sheet.
By adopting the above technical scheme, when the first inserted sheet simple shape for example in rectangle when be likely to cause through the first inserted sheet
It is connect with commutator base unstable, it is therefore desirable to the second inserted sheet be set in the other end that main leaf body is oppositely arranged hook foot, changed
It is opened up on device matrix with consistent second connected slot of the second inserted sheet shape and keeps connective stability, and when the first inserted sheet shape
When shape is complicated dovetail-shape or the other end bifurcated setting of the opposite connection main leaf body of the first inserted sheet, in commutator base first
Connected slot is then in dovetail groove profile, and this connection type is relatively firm, it may be unnecessary to the second inserted sheet of additional setting.First inserted sheet shape
Shape is not fixed, and can be set to dove-tail form, with angled inclination piece etc..
A kind of commutation piece fixed structure of above-mentioned Novel commutator can be further arranged to: first inserted sheet includes
Cross section is in the interconnecting piece of rectangle or is set to the opposite connection main leaf body other end of interconnecting piece in the opposite fixation set up of forked
Portion is arranged between two fixed parts jagged.
A kind of commutation piece fixed structure of above-mentioned Novel commutator can be further arranged to: the notch cross section is in three
It is angular or T-shaped.
By adopting the above technical scheme, the first inserted sheet, which can be set to single only interconnecting piece shape, may be set to be both
There are the two opposite shapes for setting up fixed part again with interconnecting piece, set depending on specific production technology demand.
The utility model has the following beneficial effects: manufacture difficulty is low, raw materials consumption is few and high production efficiency.
The utility model is described in further detail with reference to the accompanying drawings and examples.
