Problems solved by technology

As for the shape of the plugging hole of the brush, the current processing method is very simple, that is, a cylindrical drill bit rotating at high speed is put into the brush body for drilling, and the shape of the plugging hole drilled is generally cylindrical.
After the copper wire is implanted into the filled hole, the copper wire is almost distributed in a straight line, so the wire is mainly fixed by the density of the filled copper powder, and the fixing effect is not very ideal.

Embodiment 1

[0031] Such as figure 1 and 2 As shown, the present invention provides a kind of method that improves the stuffing detachment pulling force of wire in electric brush, comprises:

[0032] Step S1, punching a hole with a preset length on the brush body 1; the diameter of the hole from the hole 2 to the bottom 3 of the hole is the same, and the shape of the hole can be cylindrical;

[0033] Step S2, reaming the hole bottom 3 of the hole; here, the diameter of the hole bottom 3 after reaming is greater than the diameter of the hole opening, and the shape of the hole bottom 3 after reaming is trumpet-shaped or other as long as the diameter is greater than Arbitrary shape of the diameter of the orifice;

[0034] Step S3, filling the wire 4 from the hole 2 to the bottom 3 of the hole, and bending one end of the wire in the space at the bottom of the hole;

[0035] Step S4, filling copper powder between the holes and gaps of the wires. Specifically, the connection between the wire...

Embodiment 2

[0046] Such as figure 1 As shown, the present invention also provides another method and structure for improving the pulling force of the wire in the brush, including:

[0047] A hole of a predetermined length arranged on the brush body 1, the diameter of the hole bottom 3 of the hole is greater than the diameter of the hole 2;

[0048] The wire 4 stuffed in the hole, one end of the wire is bent in the space at the bottom of the hole 3;

[0049] Copper powder filled between the holes and the gaps of the wires 4 .

[0050] preferred, such as figure 1 As shown, the structure for improving the pulling force of the lead wire in the brush for packing and detaching also includes glue for sealing the hole.

[0051] Preferably, the structure for improving the pulling force of the lead wire in the brush, such as figure 1 As shown, the bottom of the hole 3 is trumpet-shaped.

[0052] For other details of Embodiment 2, refer to the corresponding part of Embodiment 1 for details, and...

Abstract

The invention provides a method and a structure for improving packing pulling force of a wire in an electric brush. A hole with a preset length is punched in an electric brush body; the diameter of the hole is the same from the hole opening to the hole bottom; the hole bottom of the hole is expanded; the diameter of the expanded hole bottom is larger than that of the hole opening; the wire is packed from the hole opening to the hole bottom; one end of the wire is bent in the space of the hole bottom; the gap between the hole and the wire is filled with copper powder; one end of the wire can be bent with enough space in a horn-shaped opening or in a hole bottom of any shape only if the diameter of the hole bottom is larger than that of the hole opening, so that the wire is prevented from being pulled out of the brush body; and therefore, the packing pulling force of the wire is greatly increased.

Description

technical field [0001] The invention relates to a method and a structure for improving the pulling force of a wire in a brush for packing and detaching. Background technique [0002] The brush body generally needs one or more wires to be connected to it, and then the wires are connected to the terminal of the motor, so as to form a normal energization circuit, and the connection between the wires and the brush body is generally through the wire pressing method. And the wire packing method to implant the wire into the brush body. The quality of the wire filling directly reflects the pulling force of the wire. The greater the pulling force, the stronger the connection and the better the conductivity. Therefore, the pulling force of the wire directly affects the performance of the brush and even whether it can be used normally; in some motor working conditions It is relatively harsh and the motor vibration is relatively large, and the wire may even fall off during the use of t...
