Abstract
The invention relates to a motor brush holder assembly, which is provided with a brush holder in a closed ring shape. A spring plate is embedded on the inner side of the brush holder and extends out of a brush holder body. A wire is wound on the spring plate. The wire is fixed in the brush holder. A preparation process of the motor brush holder assembly is implemented according to the following steps of: (1) winding the wire on the brush spring plate; and (2) loading a spring plate part wound with the wire into a die and carrying out plastic compression by using a high temperature resistant material to form the brush holder assembly. In the invention, the brush holder is made from the high temperature resistant polyimide material. The preparation process is suitable for the thin-wall plastic compression part with a plurality of inserts. The assembly is prepared by the novel process method of winding the wire on the brush spring plate, then embedding the brush spring plate wound with the wire into the brush holder and carrying out plastic compression by using the high temperature resistant polyimide material. The preparation process improves the structure strength and the conductive reliability of the motor brush holder assembly. The part material has high advancement and novelty and attractive appearance.
Description
Technical field
The invention belongs to the motor manufacturing technology field, particularly the manufacturing of motor brush frame component.
Background technology
Brush holder assemblies is the motor core component, and effect is the accurate brush transmission of electric signals by motor, realizes product function.The brush holder assemblies of present domestic high accuracy electrical micro-machine, torque motor and platform motor is most to be that matrix is installed shell fragment with folder wood glue wood, more silver-colored graphite and wire is welded on the shell fragment, and this kind structure is simpler and easy, but part life is short, and outward appearance is bad.Also bad in shell fragment welding conduction reliability.Motor is in running, when particularly running up, or duration of runs when long, if shell fragment not prison welding then connect wire and easily disconnect causes the motor clamping stagnation, affects properties of product.
Summary of the invention
The object of the invention provides a kind of motor brush frame component and new preparation process, to improve the overall performance of motor.
Specifically, a kind of motor brush frame component, it has the brush carrier that is closed ring, is inlaid with shell fragment in the brush carrier inboard and shell fragment stretches out the brush carrier body, is wound with wire at shell fragment simultaneously, and wire is fixed in the brush carrier.
The preparation technology of said motor brush holder assemblies implements in accordance with the following steps: (1) is the coiling wire on the brush shell fragment; (2) will twine shell fragment part behind the wire mould of packing into, become brush holder assemblies with the exotic material plastic compression.
Center brush frame of the present invention adopts fire resistant polyimide material, many inserts, thin-walled, plastic compression part.The technique new method of coiling wire on the brush shell fragment embeds in the brush carrier again, then becomes assembly with fire resistant polyimide material plastic compression.Improved structural strength and the conduction reliability of motor brush frame component, the advanced novelty of part material is good, outward appearance is good.
The present invention adopts the process of exotic material plastic pressure forming, wire (high temperature resistant wire) coiling shell fragment inserts, and the mould of packing into after the shell fragment part is twined becomes brush holder assemblies with the exotic material plastic compression.Adapt to many inserts, thin-walled, plastic compression part.The method all is suitable for for the brush of varying number and the motor of different size.Reliable in quality, outward appearance are good.Can produce, reduce cost in enormous quantities.
Description of drawings
Fig. 1 is motor brush frame component structural representation of the present invention.
Fig. 2 is elastic piece structure schematic diagram of the present invention.
Embodiment
Provided a kind of motor brush frame component of invention own such as Fig. 1, it has the brush carrier 2 that is closed ring, it is characterized in that being inlaid with shell fragment 1 and shell fragment 1 in the brush carrier inboard stretches out brush carrier 2 bodies, be wound with wire 1-2 at shell fragment 1 simultaneously, wire 1-2 is fixed in the brush carrier 2.The other end of wire 1-2 passes the hole from brush carrier 2.Be the elastic piece structure schematic diagram such as Fig. 2, shell fragment 1 is two and is evenly arranged on brush carrier 2 peripheries.Brush carrier 2 adopts resistant to elevated temperatures polyimide material compress molding.
The new preparation process of motor brush frame component is characterized in that preparing in accordance with the following steps: (1) is the coiling wire on the brush shell fragment; (2) will twine shell fragment part behind the wire mould of packing into, become brush holder assemblies with the exotic material plastic compression.
Claims (2)
1. motor brush frame component, has the brush carrier (2) that is closed ring, it is characterized in that being inlaid with shell fragment (1) in brush carrier (2) inboard and shell fragment (1) stretches out brush carrier (2) body, simultaneously be wound with wire (1-2) at shell fragment (1), wire (1-2) is fixed in the brush carrier (2); The other end of wire (1-2) passes the hole from brush carrier (2); Shell fragment (1) is two and is evenly arranged on brush carrier (2) periphery; Brush carrier (2) adopts resistant to elevated temperatures polyimide material compress molding.
2. the new preparation process of motor brush frame component as claimed in claim 1, it is characterized in that preparing in accordance with the following steps: (1) is the coiling wire on the brush shell fragment; (2) will twine shell fragment part behind the wire mould of packing into, become brush holder assemblies with the exotic material plastic compression.
