Abstract
The utility model discloses a conveniently-installed motor carbon brush holder which comprises a supporting plate and a carbon brush box, wherein a central hole for a commutator to extend into is formed in the supporting plate, the carbon brush box is distributed on the supporting plate at intervals around the central hole and is provided with a carbon brush channel which is communicated in the radial direction, and a carbon brush and a spring for driving the carbon brush to move towards the central hole are arranged in the carbon brush channel. The utility model has simple structure and high installation efficiency.
Description
Technical Field
The utility model relates to an improved utility model of a motor carbon brush holder, in particular to an improved utility model of a conveniently-installed motor carbon brush holder.
Background
The carbon brush of motor carbon brush holder is installed in the carbon brush box, and the carbon brush receives the effect of spring and can move towards the centre bore in the carbon brush box, consequently, when installing the commutator, need carry out spacingly with the carbon brush, wait that the commutator assembly is accomplished the back, release again and spacing to the carbon brush, make the carbon brush butt on the commutator under the effect of spring, and spacing wire on wearing to locate the carbon brush box is adopted to spacing to the carbon brush generally, have on the corresponding carbon brush box and wear to establish the hole, have the spacing groove on the carbon brush, so the structure is complicated, and is with high costs, and when the carbon brush box has a plurality of, need each to wear to establish alone to limit the position iron wire, and also need demolish one by one when dismantling, lead to the assembly trouble, inefficiency.
Disclosure of utility model
The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing the conveniently-installed motor carbon brush frame which is simple in structure and high in installation efficiency.
The utility model aims to solve the technical problems, and the technical scheme is that the portable motor carbon brush holder comprises a supporting plate and a carbon brush box, wherein a central hole for a commutator to extend in is formed in the supporting plate, the carbon brush box is distributed on the supporting plate at intervals around the central hole, the carbon brush box is provided with a carbon brush channel which is conducted radially, and a carbon brush and a spring for driving the carbon brush to move towards the central hole are arranged in the carbon brush channel.
The limiting part is an outer flange arranged at the lower end of the cylindrical body.
The cylindrical body is a hollow tube.
The carbon brush limiting part is an injection molding part.
The carbon brush box is provided with two or four carbon brush boxes, and the carbon brush boxes are circumferentially distributed on the supporting plate at equal intervals.
The improved conveniently-installed motor carbon brush holder has the beneficial effects that the carbon brush limiting piece can be quickly embedded in the central hole of the supporting plate to realize radial limiting of the carbon brushes in the carbon brush boxes, the structure is simple, the installation is convenient, the assembly efficiency and the convenience are improved, and the original structures of the carbon brush boxes and the carbon brushes are not required to be changed.
Drawings
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a structural view of a carbon brush stopper according to the present utility model.
Detailed Description
The drawings illustrate the structure of the present utility model, and details thereof are further described below with reference to the drawings. In this embodiment, this civilian dress formula motor carbon brush holder, including backup pad 1 and carbon brush box 2, be equipped with the centre bore 3 that supplies the commutator to stretch into on the backup pad 1, carbon brush box 2 is around centre bore 3 interval distribution on backup pad 1, just carbon brush box 2 has radial conduction's carbon brush passageway, is equipped with the carbon brush in the carbon brush passageway and drives the spring that the carbon brush removed towards centre bore 3, can dismantle in the centre bore 3 and be equipped with carbon brush locating part 4, this carbon brush locating part 4 is including cylindricality 41 and the spacing portion 42 that sets up in cylindricality 41 lower extreme, cylindricality 41 can match and inlay and locate in centre bore 3, the excircle and the radial spacing cooperation of carbon brush of cylindricality 41, spacing portion 42 and backup pad 1 surface axial spacing cooperation.
In the installation process of the utility model, after the spring and the carbon brush are installed in the carbon brush box 2, manual limit (by means of a special tool) is applied to the carbon brush, then the cylindrical body 41 of the carbon brush limiting part 4 is embedded into the central hole 3 from the outer side of the supporting plate 1 in sequence until the limiting part 42 contacts the outer surface of the supporting plate 1, and the corresponding carbon brush is abutted against the outer circle of the cylindrical body 41 under the action of the spring, so that the radial limit of the carbon brush is realized.
As a further improved embodiment, the limiting portion 42 is an outer flange disposed at the lower end of the cylindrical body 41, and the outer flange is integrally formed on the cylindrical body 41.
As a further improved embodiment, the cylindrical body 41 is a hollow tube, which reduces material use, saves costs, and allows the motor shaft to pass through.
As a further improved specific embodiment, the carbon brush limiting part 4 is an injection molding part, has certain plasticity, is convenient to be embedded in the central hole 3, and is convenient to manufacture and reduce cost.
As a further improved embodiment, the carbon brush box 2 is provided with two or four carbon brush boxes and is circumferentially distributed on the support plate 1 at equal intervals.
In summary, the above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
