Abstract
The utility model discloses a kind of general commutator screening core, comprise columniform main body and be connected to the screening post on main body outer circumference surface, first row film trap is formed between adjacent described screening post, described screening post both sides are provided with restriction protrusion, described restriction protrusion makes first row film trap have less entrance, it is characterized in that: described restriction protrusion is provided with along body shaft groove upwards, adjacent described groove forms second row film trap, and described first row film trap and second row film trap are of different sizes.This screening core can be applicable to the screening demand of the commutator segment of the connecting wing with different size shape, has very high versatility, thus effectively reduces the screening cost of commutator.
Description
Technical field
The utility model relates to a kind of commutator screening core.
Background technology
Commutator screening core is in the commutator course of processing, for commutator segment evenly being arranged in circular parts, it mainly comprises a columniform main body and is arranged in the screening post on main body outer circumference surface, screening groove is formed between adjacent screening post, screening groove has the space of mating with commutator segment connecting wing and this space has a less outlet, the connecting wing of commutator segment is inserted after in screening groove, commutator segment can be fixedly attached on screening core, thus make some commutator segments on screening core one week arrangement in circular.Exactly because the spatial form of screening groove will match with the connecting wing of commutator segment, the commutator segment so dissimilar with the connecting wing of different size shape needs when screening to use different specific screening cores, and this is undoubtedly for increasing the processing cost of commutator.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of general commutator screening core that can be applicable to the screening of the commutator segment of the connecting wing with different size shape.
For this reason, the utility model realizes in the following way: a kind of general commutator screening core, comprise columniform main body and be connected to the screening post on main body outer circumference surface, first row film trap is formed between adjacent described screening post, described screening post both sides are provided with restriction protrusion, described restriction protrusion makes first row film trap have less entrance, it is characterized in that: described restriction protrusion is provided with along body shaft groove upwards, adjacent described groove forms second row film trap, and described first row film trap and second row film trap are of different sizes.
Described screening post and main body removably connect.
Described screening post rear end has the T-shaped locating piece in cross section, and described main body is provided with the location notch mated with locating piece, and described locating piece is placed in location notch.
In the utility model, same screening core has the screening groove that at least two sizes are different, thus make this screening core can be used to the screening of different commutator segment, saved the cost of screening, and then saved the processing cost of commutator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, this general commutator screening core, the screening post 2 comprising columniform main body 1 and be connected on main body 1 outer circumference surface, first row film trap 6 is formed between adjacent described screening post 2, described screening post 2 both sides are provided with restriction protrusion 3, described restriction protrusion 3 makes first row film trap 6 have less entrance, described restriction protrusion 3 is provided with along body shaft groove 4 upwards, adjacent described groove 4 forms second row film trap 5, described first row film trap 6 is of different sizes with second row film trap 5, described screening post 2 removably connects with main body 1, specifically, described screening post 2 rear end has the T-shaped locating piece in cross section 7, described main body 1 is provided with the location notch mated with locating piece 7, described locating piece 7 is placed in location notch.In said structure, the different first row film trap 6 of size and second row film trap 5 is formed between adjacent screening post 2, the connecting wing of the different size shape that first row film trap 6 and second row film trap 5 have from different commutator segment respectively matches, when actual screening, different screening grooves can be selected as required to carry out screening, and be not required to be often kind of different special different screening core of commutator segment, reduce processing cost.And the removably connecting of screening post 2 and main body 1, screening post 2 can be coordinated with the main body of different size, this just can enable core be applicable to the different demands of commutator when screening of different size, further enhance the versatility of this screening core, and effectively reduce the production cost of commutator.Certainly, in said structure, as required can also multiple groove be set in restriction protrusion, thus obtains the different screening groove of more size, thus meet the screening demand of how different commutator segment.
