Description
1, technical field:
The present invention relates to a kind of by the motor-driven wire cutting machine tool bit structure of dc brushless external rotor.
2, background technology:
At present; The clothing industry is used a kind of trimming equipment gradually; It is the trimming machine; The patent No. is: 022729038, patent name is: a kind of cutter head assembly, notification number of trimming machine machine are: the patent of invention of CN2579925Y discloses its operation principle; It comprises blade assembly, transmission mechanism, housing and compositions such as cutter head stay pipe, air-breathing shape tube, and wherein blade assembly comprises the blade folder composition of cutting blade, fixed blade and clamping blade, and transmission mechanism comprises eccentric shaft, bearing, driving sliding block composition.There is following shortcoming in this trimming machine: 1) drives with alternating current generator, and carbon brush quick abrasion in the motor, the fault rate that carbon brush takes place is very high; 2) alternating current generator separates with wire cutting machine tool bit, uses the flexible axle transferring power between them, makes wire cutting machine tool bit structure complicated, and manufacturing cost is high; 3) structure is compact inadequately, and volume is big, take up room, and wire cutting machine tool bit is not too convenient during use at the back through flexible axle connection alternating current generator; 4) adstante febre does not have suitable radiator structure, and noise is big.
To above-mentioned technical problem; The technical scheme that this case patent applicant research makes new advances; And to national patent patent application is proposed on March 31st, 2007, and its number of patent application is: 200720049984.8, and name is called: " a kind of wire cutting machine tool bit structure by driven by Brush-Less DC motor ".This technical scheme has solved above-mentioned technical problem basically, but still there is following technical problem in it, is necessary further perfect.Its technical problem is: the dc brushless motor that 1) adopts is an inner rotor motor, and the radial distance of rotor and rotating shaft is smaller, so under the equal conditions, the torque ratio of generation is less; Want to produce bigger moment, meet the requirement of trimming machine, must improve the power of motor; But the raising power of motor, relatively power consumption, and it is serious to make that the motor feels hot; Therefore, must install heat sink additional in the motor outside, with heat radiation as early as possible.2) heat sink of motor and motor outside must be positioned at the enclosure of wire cutting machine tool bit, and therefore, not attractive in appearance, globality is poor, and volume is bigger, and it is not too convenient to install, inconvenient operation, and manufacturing cost is high; 3) powerful brush DC inner rotor motor, noise is big, power consumption; 4) heat sink of motor and motor outside must be positioned at the enclosure of wire cutting machine tool bit, and the people touches motor radiating plate and electrode in operation easily, when motor produces electric leakage, has potential safety hazard.
3, summary of the invention:
In order to overcome the deficiency of above-mentioned prior art, the objective of the invention is to carry that a kind of it is simple and compact for structure by the motor-driven wire cutting machine tool bit structure of dc brushless external rotor, easy for installation, volume is fewer, and is in light weight, energy-conservation, noise is little.
The present invention realizes through following technical scheme:
A kind of by the motor-driven wire cutting machine tool bit structure of dc brushless external rotor; Comprise shell and blade assembly, blade assembly is installed in cover top portion, and housings is provided with the negative pressure air-suction channel; The negative pressure air-suction channel be communicated to blade assembly below; Next door, cover top portion at the negative pressure air-suction channel are equipped with the dc brushless external rotor motor, and the output shaft upper top of dc brushless external rotor motor connects slide block, and slide block is embedded into the chute the inside of the cutting blade of blade assembly.It has following advantage: the brush DC inner rotor motor that adopts in the originally existing wire cutting machine tool bit structure, the power of motor of use are about 20 watts, need heat sink is installed, and the radial distance of rotor and rotating shaft is smaller; After adopting technical scheme of the present invention, the radial distance of rotor and rotating shaft doubles, and power of motor is about 10 watts, and moment can meet the demands; Need not adopt heat sink, therefore more energy-conservation, and also noise reduces greatly; Volume is littler, and structure is compact more, and it is little that the motor feels hot; Fault can further reduce, and installs simple and conveniently, and manufacturing cost is lower.
Above-mentioned described output shaft is an eccentric shaft.
The above-mentioned said motor slot that is complementary with dc brushless external rotor motor outside dimension that inside cover top portion, is provided with, the dc brushless external rotor motor is nested in the motor slot the inside.Owing to cancelled heat sink, it is little that the motor feels hot, and therefore, whole motor can be directly installed on housings; Structure gold is more gathered, and installation is more prone to, and uses convenient; Globality is strong, and good looking appearance is simultaneously when operation; Human body and motor are kept apart, increase Product Safety, and can further lower the noise that motor produces.
Above-mentioned described cover top portion one side is provided with atomizer, and atomizer is positioned near the blade assembly, and atomizer connects oil pump through oil pipe.It reduces the wearing and tearing between fixed blade and the cutting blade regularly to the blade assembly lubricating oil spraying, can prolong the blade assembly working life, lowers use cost.
Above-mentioned described enclosure also is provided with supporting boss.
The above-mentioned said motor cover plate that on motor slot, is equipped with, output shaft passes the motor cover plate, and the slide block on the output shaft is positioned at motor cover plate top.The motor cover plate is positioned at the motor slot the inside with motor.
Above-mentionedly saidly below the dc brushless external rotor motor, on the shell, have heat dissipation channel, it distributes the heat in the machine operation.
