Abstract
A paint scraping device is provided, wherein a motor is arranged in the casing of the paint scraping device, a paint scraper is arranged on the front end of an output shaft of the motor, a speed governing switch for regulating the rotary speed of the motor is arranged on the back portion of the motor, and a control switch can control the work of the motor through a control wiring board. A radiating fan is arranged in the casing, and the radiating fan and the control wiring board are arranged on the back portion of the motor, the back portion of the casing and the fan are provided with air outlets, a transparent protecting hood is arranged on the front end of the casing corresponding to the paint scraper, a lead cover with threading holes is arranged on the front end of the transparent protecting hood, and the motor is a brushless motor. As the radiating fan is arranged in the casing, heat energy generated by the brushless motor and the control wiring board can be exhausted out of the casing in time, thereby ensuring components not to overheat, and making the work of the paint scraping device stable.
Description
Technical field:
The utility model relates to a kind of electronic paint scraper that scrapes off the magnet wire insulation layer.
Background technology
Enamelled wire need be removed the insulating barrier on top layer earlier when being connected with other electric elements.In order to remove its surperficial enamelled coating efficiently, Chinese patent just provides " the electronic paint scraper of a kind of enamelled wire " for No. 02217204.1.In this technical scheme, electronic paint scraper comprises housing, electronic stepless speed regulation circuit in the prior art, paint chipping chisel assembly and motor in the prior art, motor comprises stator, rotor and brush, brush adopts the rotary extrusion type spinning carbon brush in the prior art, the rotary extrusion type spinning carbon brush is fixed on the housing by the carbon brush pipe in the prior art, the rotary extrusion type spinning carbon brush is axial perpendicular to the motor rotor, the epitrochanterian commutator of the end face of rotary extrusion type spinning carbon brush and motor contacts, the axle of the rotor in paint chipping chisel assembly and the motor is connected, the brush of motor is connected by lead with the electronic stepless speed regulation circuit, be provided with a by-pass cock in the prior art in the electronic stepless speed regulation circuit, can change the rotating speed of described motor, thereby the work of control paint chipping chisel assembly, the dismounting carbon brush that it can be more convenient.But have the following disadvantages:
When 1, above-mentioned paint scraper used, motor and control circuit board can produce a large amount of heats, are easy to cause each device overheated, make that the paint scraper job stability is undesirable, can not work long hours continuously.
When 2, above-mentioned paint scraper uses, because protecting cover is opaque, the quantity of lacquer bits in progress that can't be real-time observe scraped lacquer and the protecting cover, it is inconvenient to make paint scraper use.
When 3, above-mentioned paint scraper used, the wearing and tearing of carbon brush can produce conductive powder, and conductive powder amasss in casing and on each element, damages paint scraper thereby be short-circuited easily.
Summary of the invention
The purpose of this utility model is: the paint scraper that a kind of working stability, perfect heat-dissipating, long service life are provided.
The utility model is achieved through the following technical solutions:
A kind of paint scraper is provided with motor in the paint scraper casing, and the motor output shaft front end is provided with paint chipping chisel, and the motor rear portion is provided with the speed-regulating switch that is used to regulate motor speed, and control switch is controlled machine operation by control circuit board; It is characterized in that: be provided with radiator fan in the described casing, radiator fan and control circuit board are located at the motor rear portion, casing rear portion and fan relevant position are provided with air outlet, casing front end and paint chipping chisel corresponding position are provided with transparent cover, the transparent cover front end is provided with the wire cover of band through wires hole, and described motor is a brushless electric machine.
Advantage of the present utility model is: owing to be provided with radiator fan in the casing, radiator fan and control circuit board are located at the motor rear portion, casing rear portion and fan relevant position are provided with air outlet, can discharge the heat of brushless electric machine and control circuit board generation outside the casing timely, to guarantee that each element can be not overheated, make and the paint scraper working stability can work long hours continuously.Because casing front end and paint chipping chisel corresponding position are provided with transparent cover, the transparent cover front end is provided with the wire cover of band through wires hole, can scrape the quantity of lacquer bits in lacquer progress and the protecting cover during use by the transparent cover Real Time Observation, and it is more convenient to make that paint scraper uses.Because motor is a brushless electric machine, brushless electric machine can be avoided producing conductive powder and damage each element, thereby has prolonged the useful life of paint scraper.Simultaneously, the use of brushless electric machine can be saved the trouble that needs to change carbon brush in the prior art, makes that the service behaviour of paint scraper is better.
In the utility model, described casing is assembled by the last lower house that cooperatively interacts, and the casing front end is provided with the screw thread that cooperatively interacts with transparent cover.Said structure can be pulled down protecting cover easily from casing, make that pouring out lacquer considers to be worth doing easy to operate.
Description of drawings
Fig. 1 is the schematic diagram of the utility model specific embodiment.
Embodiment
As shown in Figure 1: the paint scraper of present embodiment comprises: casing 1, be provided with motor 4 in 2, motor 4 output shaft front ends are provided with paint chipping chisel 3, motor 4 rear portions are provided with the speed-regulating switch 6 that is used to regulate motor speed, control switch 7 is by 4 work of control circuit board 12 control motors, casing 1, be provided with radiator fan 5 in 2, radiator fan 5 and control circuit board 12 are located at motor 4 rear portions, casing 1 and 2 rear portions and fan 5 relevant positions are provided with air outlet 11, casing 1 and 2 front ends and paint chipping chisel 3 corresponding positions are provided with transparent cover 8, transparent cover 8 front ends are provided with the wire cover 9 of band through wires hole, the motor 4 of present embodiment is a brushless electric machine, casing is assembled by the last lower house 1 and 2 that cooperatively interacts, and the casing front end is provided with screw thread 10A and the 10B that cooperatively interacts with transparent cover 8.Press control switch 7, motor 4 drives paint chipping chisels 3 work, and the through wires hole of enamelled wire by wire cover 9 inserted the work that the service position of paint chipping chisel 3 can be removed the insulating barrier on top layer to enamelled wire.
Owing to be provided with radiator fan in the casing, the heat of brushless electric machine and control circuit board generation can be discharged outside the casing timely, can be not overheated to guarantee each element, make the paint scraper working stability to work long hours continuously.Because casing front end and paint chipping chisel corresponding position are provided with transparent cover, can scrape the quantity of lacquer bits in lacquer progress and the protecting cover during use by the transparent cover Real Time Observation, it is more convenient to make that paint scraper uses.Because motor is a brushless electric machine, brushless electric machine can be avoided producing conductive powder and damage each element, thereby has prolonged the useful life of paint scraper.Simultaneously, the use of brushless electric machine can be saved the trouble that needs to change carbon brush in the prior art, makes that the service behaviour of paint scraper is better.The paint scraper of present embodiment can be pulled down protecting cover easily from casing, make that pouring out lacquer considers to be worth doing easy to operate.
