Abstract
The utility model discloses a 7-shaped commutator segment for a motor commutator, comprising a commutator segment body (1) and a dovetail (2), wherein the commutator segment body (1) has a lifting sheet part (4) and the longitudinal section of the commutator segment body (1) is a 7-shaped structure. The utility model can design a short welding groove on the top surface of the 7-shaped short edge of the commutator segment body, is convenient to process; and closely fits with a carbon brush on the combination part of the working face part and the lifting sheet part of the commutator segment bodyand simultaneously will not cause the material waste thus the commutator segment material utilization ratio is high. When the commutator segment body working face is turned, the processing allowanceis small so as to improve the operating efficiency; reduce the heat owing to turnings and promote the work performance of the commutator product.
Description
One, technical field
The utility model relates to the commutator segment that a kind of engine commutator is used.
Two, background technology
Existing commutator is made of commutator segment, moulding compound etc. usually, wherein commutator segment comprises commutator segment body and dovetail, be rectangle shape, longitudinal section of the cross section of commutator segment body is trapezoidal shape, bonding wire groove (promptly being designed to the linear groove of straight horizontal) also to be set at the end face of this commutator segment body after making the commutator product as required be used for motor point welding lacquered wire, but the bonding wire line of rabbet joint bar of processing this commutator segment body end face is long, the operation trouble is time-consuming, and operating efficiency is not high.This external surface of commutator segment that cooperates with carbon brush needs through repeatedly turning is to reach and the carbon brush matched size, and the part that the cylindrical car removes forms copper scale, causes waste of material, production cost height.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, can make short, easy to process " 7 " the font commutator segment simple, that reduce with carbon brush compatible portion car bits surplus of processing bonding wire line of rabbet joint bar on the commutator segment body end face and provide a kind of.
The purpose of this utility model realizes by following technical solution: a kind of " 7 " font commutator segment, comprise commutator segment body and dovetail, and described commutator segment body has the rise piece position, and the longitudinal section of this commutator segment body is " 7 " font structure.
After adopting the utility model structure, can on the end face of " 7 " of commutator segment body font minor face, design the bonding wire groove of short-term bar, process simple and convenient; Can also can not cause waste of material simultaneously in the work that closely cooperates of the junction at commutator segment body working face position and rise piece position and carbon brush.Thereby make commutator segment stock utilization height, saved the commutator segment material; When car bits commutator segment body working face, its allowance is few, increases work efficiency; Minimizing has promoted the service behaviour of commutator product because of the heat that the car bits produce.
Four, description of drawings
Below in conjunction with accompanying drawing and execution mode the utility model is described in further detail.
Fig. 1 is the structural representation of known commutator segment.
Fig. 2 is the vertical view of Fig. 1 (as make behind the commutator product processing).
Fig. 3 is the structural representation of the utility model " 7 " font commutator segment.
Fig. 4 is the vertical view of Fig. 3 (as make behind the commutator product processing).
Five, embodiment
With reference to Fig. 1, Fig. 2 as can be known, the cross section of the commutator segment body of the known commutator segment shape that is rectangle, as after making commutator product and processing, the bonding wire line of rabbet joint bar on the commutator segment body end face is longer, the processing trouble is time-consuming.
With reference to Fig. 3, Fig. 4 as can be known, the utility model " 7 " font commutator segment, comprise commutator segment body 1 and dovetail 2, described commutator segment body 1 has rise piece position 4, and commutator segment body 1 has with the rise piece position 4 of carbon brush for electric machine coupling (can by bending process to form the rise piece position) and working face 3 and (can form by drawing process; Conventional products allowance is many, waste of material, and the production cost height, and when turning, produce heat, and cause commutator segment and moulding compound adhesive property to reduce), the longitudinal section of this commutator segment body 1 is " 7 " font structure.As shown in Figure 4, as make the commutator product and processing after, the bonding wire line of rabbet joint bar 5 on the end face of " 7 " font minor face of commutator segment body 1 is shorter, easy to process saving time.
Claims (1)
1, a kind of " 7 " font commutator segment comprises commutator segment body (1) and dovetail (2), and it is characterized in that: described commutator segment body (1) has rise piece position (4), and the longitudinal section of this commutator segment body (1) is " 7 " font structure.
