Abstract
The utility model relates to a cutting tool, in particular to a dust-proof and water-splashing-prevention device for output shafts of cutting tools. The device comprises a head casing, a gear, the output shaft, a deep groove ball bearing, a front cover and a cutting sheet. The gear is installed in the head casing, the output shaft is arranged in the front cover, the gear is connected with the output shaft, a dust-proof ring is arranged on the output shaft, the deep groove ball bearing is installed in the output shaft and the head casing, the cutting sheet is installed between an inner pressing plate and an outer pressing plate, a screw hole is arranged on the front cover, the cutting sheet is fixed through the inner pressing plate and the outer pressing plate, the front cover is connected with the head casing through a screw, and the dust-proof ring pressing on the output shaft and the front cover form a labyrinth shape to prevent dust. In the working process of the machine, a certain gap is maintained between the dust-proof ring and the front cover without mutual friction, and accordingly dust-proof and water-splashing-prevention functions are achieved, and service life of the whole machine is prolonged.
Description
Technical field
The utility model relates to a kind of cutting kind tool, relates in particular to dustproof, the Splash-preventing device of a kind of cutting machine kind tool output shaft.
Background technology
Under whole background on the low side of electronic cutting kind tool life-span, through improving partial structurtes,, improve its effect through the dustproof mode of improving the output shaft place exactly here, to improve the life-span of cutting kind tool to improve its machine life.Existing structure is main with lip-type packing and O shape circle mainly, dust and water protection spatter effect still can, but because rotation at a high speed here, lip-type packing is easy to wear and cause the machine water inlet, advance dirt with O shape circle, and can't carry out heat exchange with the outside, the reduction service life of a machine.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, provides a kind of cutting kind tool output shaft dustproof, Splash-preventing device.
For reaching above-mentioned purpose; The utility model is realized through following technical scheme: a kind of cutting kind tool output shaft is dustproof, Splash-preventing device, mainly comprises head capsule, gear, output shaft, deep groove ball bearing, protecgulum, cutting blade, and it is characterized in that: described gear is installed in the head capsule; Be provided with output shaft in the described protecgulum; Said gear is connected with output shaft, and said output shaft is provided with dust ring, in described output shaft and the head capsule deep groove ball bearing is housed; Said cutting blade is installed between interior pressure strip and the external compression plate; Said protecgulum is provided with screw hole, and said cutting blade is fixed through interior pressure strip, external compression plate, and said protecgulum is connected with head capsule through screw.Said dust ring and the protecgulum formation labyrinth-like that is pressed on the output shaft spattered, and made things convenient for heat exchange with dustproof, waterproof.
Such scheme is done further analysis: the rotation of energising rear motor rotor high-speed, and through the rotation of gear drive drive output shaft, the dust ring and the protecgulum that are pressed on the output shaft form the labyrinth with dustproof.In the machine works process, dust ring and protecgulum keep certain clearance, do not have mutual friction, have so both played dustproofly, and the effect that waterproof is spattered has improved machine life again.
The beneficial effect of the utility model is: dust ring on output shaft and protecgulum form labyrinth-like, can realize the dustproof and waterproof function, and deep groove ball bearing and motor are prolonged service life.
