Abstract
The utility model discloses a kind of tank commutator, the commutator segment comprising die body and evenly lay at die body excircle, the two ends of commutator segment are carried out radial direction by reinforcing ring and are fixed, every commutator segment is provided with upper and lower two sheet pin and implants in die body and die body strong bonded, it is characterized in that: the top that described commutator segment arranges bonding wire groove step one end has and raises up, and described reinforcing ring snaps onto this outer rim raised up; One in two sheet pin up and down of every commutator segment arranges reinforcement pin at medial surface, and the reinforcement pin of adjacent commutator segment is arranged in commutator short transverse and mutually staggers.What the utility model can prevent commutator segment from occurring when snapping wire casing arranges phenomenon, and the stressing conditions improved when commutator segment works, the utility model can strengthen the bond strength between commutator segment and die body simultaneously, improves structural stability and the mechanical performance of commutator product.
Description
[technical field]
The utility model relates to a kind of commutator, what be specifically related to is a kind of tank commutator.
[background technology]
Tank commutator is used widely in electric tool, the usual structure of tank commutator has: the commutator segment comprising die body and evenly lay at die body excircle, commutator segment is L-type, the two ends of commutator segment are carried out radial direction by reinforcing ring and are fixed, and every commutator segment is provided with upper and lower two sheet pin and implants in die body and die body strong bonded.Shortcoming is: 1. the two ends of commutator segment all punching grooves, and reinforcing ring embeds in groove just, and commutator segment to be carried out radial direction fixing, due to the two ends punching groove of commutator segment, obviously can weaken the intensity of commutator segment bonding wire groove step, so when carrying out offering bonding wire groove on the bonding wire groove step of commutator segment, that easily causes commutator segment bonding wire groove step arranges phenomenon, in addition because the very most quality of commutator segment concentrated by the bonding wire groove step of commutator segment, commutator segment two ends stressing conditions can be caused bad; 2. for improving the mechanical performance of tank commutator, the bond strength between commutator segment and die body need be strengthened, the best way arranges reinforcement pin at the medial surface of sheet pin, but sheet pin medial surface arranges the problem strengthening tape to be had, one is that distance between adjacent reinforcement pin can be very near, easily collide in commutator manufacturing process and contact and cause waste product, two be strengthen the space of pin periphery can be less, be unfavorable for the filling of die body material, thus affect structural stability and the mechanical performance of commutator product.
[summary of the invention]
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of commutator segment that prevents to occur when snapping wire casing arranging and improve stressing conditions when commutator segment works, the bond strength between commutator segment and die body can be strengthened simultaneously, improve the tank commutator of product structure stability and mechanical performance.
The utility model is implemented by following technical solution:
A kind of tank commutator, the commutator segment comprising die body and evenly lay at die body excircle, the two ends of commutator segment are carried out radial direction by reinforcing ring and are fixed, every commutator segment is provided with upper and lower two sheet pin and implants in die body and die body strong bonded, it is characterized in that: the top that described commutator segment arranges bonding wire groove step one end has and raises up, and described reinforcing ring snaps onto this outer rim raised up; One in two sheet pin up and down of every commutator segment arranges reinforcement pin at medial surface, and the reinforcement pin of adjacent commutator segment is arranged in commutator short transverse and mutually staggers.
After adopting technique scheme, the beneficial effect that the utility model realizes is: 1. commutator segment arranges bonding wire groove step one end without punching groove, but by arrange convex to reinforcing ring carry out radial direction fix, the intensity of commutator segment bonding wire groove step would not be weakened like this, occur when avoiding offering bonding wire groove arranging phenomenon, the decentralization of commutator segment bonding wire groove step, can improve the stressing conditions at commutator segment two ends simultaneously; 2. the sheet pin medial surface of commutator segment is not only provided with reinforcement pin but also mutually staggers, so the bond strength between commutator segment and die body not only can be strengthened, hypotelorism and strengthen the too small technical problem of pin peripheral space between the reinforcement pin that can overcome again adjacent commutator segment, thus improve structural stability and the mechanical performance of commutator product.
[accompanying drawing explanation]
The utility model has the following drawings:
Fig. 1 is structural representation of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing specific embodiment of the utility model be described in detail and illustrate:
As shown in Figure 1, tank commutator of the present utility model, the commutator segment 1 comprising die body 7 and evenly lay at die body 7 excircle, commutator segment 1 is in L-type, the two ends of commutator segment 1 are carried out radial direction by reinforcing ring 5 and are fixed, every commutator segment 1 be provided with upper and lower two sheet pin 2 implant in die body 7 with die body 7 strong bonded, the top that described commutator segment 1 arranges bonding wire groove step 6 one end has and raises up 3, described reinforcing ring 5 snap onto this raise up 3 outer rim; One in two sheet pin 2 up and down of every commutator segment 1 arranges reinforcement pin 4 at medial surface, and the reinforcement pin 4 of adjacent commutator segment 1 is arranged in commutator short transverse and mutually staggers, be specially: in two adjacent commutator segments, the medial surface of upper slice pin of a commutator segment arranges reinforcement pin, and the medial surface of the bottom sheet pin of another commutator segment arranges reinforcement pin.
