Description
Technical field
The utility model relates to commutator fields, and in particular to a kind of electrical carbon commutator.
Background technique
Existing flat carbon commutator, including commutator segment, moulding compound, carbon block, the rotation of the ontology and the commutator of commutator segment
Shaft axis is perpendicular, and carbon block is located on the outer surface of the ontology of commutator segment and integrally covers commutator segment, but this structure exists not
Foot, in the welding of electrical carbon piece, concentricity be cannot be guaranteed, and be typically only capable to determine by the experience of operator, therefore not only add
Work low efficiency and rejection rate is also higher.
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 electrical carbon commutator is provided.
To achieve the above object, the utility model provides following technical solution: a kind of electrical carbon commutator, includes commutation
Piece, moulding compound, the commutator segment are spaced apart in the outer peripheral surface of moulding compound one end, and the moulding compound other end is provided in a ring
Eight carbon blocks being arranged on moulding compound are provided with gap between each carbon block, it is characterised in that: moulding compound is oppositely arranged commutator segment
The other end outer peripheral surface locating piece is provided between adjacent commutator segment, the locating piece is the first copper sheet being oppositely arranged and
Two copper sheets, the gap setting of first copper sheet and second copper sheet one end between carbon block and one end and commutation far from gap
The axis of piece is parallel.
By adopting the above technical scheme, traditional electrical carbon commutator does not have anchor point on moulding compound, therefore welds in the later period
Concentricity cannot be guaranteed when connecing electrical carbon piece, cause production efficiency low and high rejection rate, and the utility model is used in moulding compound phase
Locating piece is arranged between adjacent commutator segment to the other end outer peripheral surface of setting commutator segment, welding electrical carbon is guaranteed by the locating piece
The concentricity of piece and experience no requirement (NR) to operator.
A kind of above-mentioned electrical carbon commutator can be further arranged to: first copper sheet and the second copper sheet are towards commutator segment
One end is all provided with jagged.
A kind of above-mentioned electrical carbon commutator can be further arranged to: first copper sheet and the second copper sheet are in L-shaped.
By adopting the above technical scheme, the utility model is by being oppositely arranged the outer peripheral surface of carbon block one end in moulding compound in carbon block
Between gap location the first copper sheet and the second copper sheet be set, the convenient concentricity for guaranteeing electrical carbon piece when welding electrical carbon piece in the later period,
And guarantee that the firmness after the welding of electrical carbon piece, electrical carbon piece are electric after welding with copper sheet by the first copper sheet of setting and the second copper sheet
The resistance of carbon plate also obtains a degree of improvement, substantially increases the performance of electrical carbon commutator.
The utility model has the following beneficial effects: guarantee the concentricity after the welding of electrical carbon piece, the jail after increasing the welding of electrical carbon piece
Gu degree improves service life, the resistive performance for improving electrical carbon piece greatly improves the performance of commutator.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the schematic elevation view of the utility model embodiment.
Fig. 2 is the schematic side view of the utility model embodiment.
Specific embodiment
Referring to shown in Fig. 1-Fig. 2: a kind of electrical carbon commutator, includes commutator segment 1, moulding compound 2, and commutator segment 1 is spaced apart
Outer peripheral surface in 2 one end of moulding compound, 2 other end of moulding compound are provided with eight carbon blocks 3 being arranged on moulding compound 2 in a ring, respectively
Gap 4 is provided between carbon block 3, the other end outer peripheral surface that moulding compound 2 is oppositely arranged commutator segment 1 is set between adjacent commutator segment 1
It is equipped with locating piece, locating piece is the first copper sheet 5 and the second copper sheet 6 being oppositely arranged, and the first copper sheet 5 and 6 one end of the second copper sheet are leaned on
One end of the setting of gap 4 and separate gap 4 between nearly carbon block 3 is parallel with the axis of commutator segment 1, and the first copper sheet 5 and direction are changed
It is equipped with the first notch 51 to one end of piece 1, the second copper sheet 6 is equipped with the second notch 61 towards one end of commutator segment 1.
