Abstract
The utility model discloses a hand-held dust-proof angular grinding and polishing machine. The angular grinding and polishing machine comprises a handle (4), a switch (3), a shell body (8), a commutator (5), a stator/rotator (7, 6), a fan (10), a head capsule (12) and a gear transmission mechanism (13), wherein the head capsule (12) is provided with a front air outlet (11) and a lower air outlet (15); the lower part of the handle (4) is provided with an air duct (2); the front end of the air duct (2) is communicated with a cooling air duct (17); the tail end of the cooling air duct (17) is provided with an air intake port (16); the cooling air duct (17) is connected with the lower air outlet (15) through the commutator (5), the stator/rotator (7, 6), the fan (10) and the front air outlet (11) on the head capsule; the air intake port (16) is connected with an air inlet pipe (1), thereby keeping away from hostile working conditions. With the adoption of the structure, the angular grinding and polishing machine has the advantages of simple structure, high security, strong reliability, long service life, etc.
Description
Technical field
The utility model relates to a kind of electric tool, the particularly a kind of dustproof angle polishing of hand-held and polishing machine that can carry out work under adverse circumstances.
Background technology
As everyone knows, hand held electric tool in the market such as electric angle grinder, polishing machine etc. comprise handle, switch, casing, commutator, rotor, fan, head capsule, gear drive, air inlet is opened in the both sides of casing or handle usually, on head capsule, offer front air outlet and following air outlet, during work under the fan effect, cooling air enters through commutator, rotor from air inlet, discharges from air outlet and following air outlet then, thereby makes the motor cooling.Because electric angle grinder, polishing machine are often worked under working environment comparison harsh conditions, bigger such as dust, working region temperature height, grinding metal, stone, polishing etc., air inlet is closer from the working region, dust, metal fillings end etc. enter in the instrument easily, make commutator, bearing and gear drive wearing and tearing aggravation, destroy insulation, cause short circuit, quicken tool damage, even the security of instrument self is worked the mischief.For this reason, many manufacturers and knowledgeable people develop and study at the problems referred to above, but do not find comparatively reasonably solution so far as yet.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing hand-held angle polishing and polishing machine exist, the purpose of this utility model is to provide a kind of simple and reasonable, flexible and convenient operation, the dustproof angle polishing of hand-held safe and reliable, that the life-span is long and polishing machine by the air intake mode that changes instrument.
The technical scheme that its technical problem that solves the utility model adopts, it comprises handle, switch, casing, commutator, rotor, fan, head capsule, gear drive, head capsule is provided with front air outlet and following air outlet, the bottom of described handle is provided with ventilating duct, the ventilating duct front end communicates with cooling air channel, its tail end is provided with the air intake interface, and cooling air channel links to each other with following air outlet with front air outlet on the head capsule through commutator, rotor, fan.
Further preferred version of the present utility model is connected with blast pipe on the described air intake interface, during work from suck relatively cleaner cooling air away from the working region.
Further preferred version of the present utility model, described casing is provided with wind loop, improves the radiating effect of rotor.
After adopting said structure, the utility model has following advantage compared with the prior art: during tool using, the operator can select the entrance location of cooling air according to the quality of working environment by blast pipe, make air inlet away from bad working environment, perhaps be connected with extraneous source of the gas, the cooling air that instrument is sucked is clean relatively; So not only can improve the cooling effect of electric machine rotor, and can significantly reduce dust, metal fillings end or other impurity that enters in the motor, make the wearing and tearing of commutator, bearing and gear drive drop to minimum, electrical machine insulation can not be damaged, thereby reaches the security performance of raising instrument and the purpose that increases the service life.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Shown in Figure 1, specific embodiments for dustproof angle polishing of the utility model hand-held and polishing machine, it comprises handle 4, switch 3, casing 8, commutator 5, rotor 7,6, fan 10, head capsule 12, gear drive 13, casing 8 is provided with wind loop 9, head capsule 12 is provided with front air outlet 11 and following air outlet 15, fixedly connected grinding wheel 14 of the output shaft of gear drive 13 or polishing wheel, the bottom of described handle 4 is provided with ventilating duct 2, ventilating duct 2 front ends communicate with cooling air channel 17, its tail end is provided with air intake interface 16, cooling air channel 17 is through commutator 5, rotor 7,6, fan 10 links to each other with following air outlet 15 with front air outlet 11 on the head capsule, is connected with blast pipe 1 on the air intake interface 16.The air inlet position of blast pipe 1 can be selected according to working environment, perhaps is connected with extraneous source of the gas, can effectively avoid bad working environment.
Claims (3)
1, dustproof angle polishing of a kind of hand-held and polishing machine, comprise handle (4), switch (3), casing (8), commutator (5), rotor (7,6), fan (10), head capsule (12), gear drive (13), head capsule (12) is provided with front air outlet (11) and following air outlet (15), it is characterized in that: the bottom of described handle (4) is provided with ventilating duct (2), ventilating duct (2) front end communicates with cooling air channel (17), its tail end is provided with air intake interface (16), and cooling air channel (17) is through commutator (5), rotor (7,6), fan (10) links to each other with following air outlet (15) with front air outlet (11) on the head capsule.
