Abstract
The utility model relates to a safety dust-catching grinding wheel which adopts a combined type protective cover composed of a fixed protective outer cover, a telescopic movable inner cover and a rotary movable inner cover. The telescopic movable inner cover can telescope front and back according to the size of a grinding wheel. The size of the opening of the rotary movable inner cover can be decided according to the dimension of a workpiece. The safety dust-catching grinding wheel is provided with a small suction cleaner. The contact time of the grinding wheel with the workpiece is short, the time of run idle is long, and the power need by the suction cleaner is small, so the suction cleaner needs no external power, and the suction cleaner can be driven by the motor of the grinding wheel. The utility model has the advantages of compact structure, high safety, less noise, no dust and no environment pollution.
Description
The utility model belongs to abrasive machine.
Existing abrasive machine protective cover protection imprecision causes industrial accident easily, and abrasive machine itself is not with dust catcher, has only professional workshop that large-scale dust collection equipment just is installed, and noise is big, and the most of airborne release of dust, is harmful to health, contaminated environment.
The utility model is at above-mentioned deficiency, provides that a kind of noise is little, free from dust, new type of safe dust suction abrasive machine free from environmental pollution.
Task of the present utility model is finished as follows: safty shield is communicated with dust catcher by sweep-up pipe, and dust catcher is communicated with box style substructure, and during work, the flying dust that the dust catcher impeller produces grinding sucks the box base.
Safty shield adopts the fixedly modular guard cover of outer protective cover, telescopic movable inner cover and rotation activity inner cover formation, and the telescopic movable inner cover can be according to the emery wheel size and elastic, and rotation activity inner cover can be determined openings of sizes according to workpiece size.
Because workpiece and emery wheel are short time of contact, idle running is long, and the dust catcher required drive is little, so dust suction need not additionaling power, is got final product by the grinding wheel drive mitor drive.Emery wheel removes working face and exposes to the open air, and all the other all cover in the cover, do not hurt sb.'s feelings so the emery wheel fragmentation can not fly out.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model general assembly drawing.
Fig. 2 is the safty shield structure chart.
With reference to accompanying drawing 2, be equipped with on the fixedly outer protective cover ［ 7 ］ in the safty shield ［ 4 ］ and can wrap the dodge gate ［ 8 ］ that leaf ［ 9 ］ rotates, close and use nut ［ 13 ］ fixing behind the door.And the telescopic movable inner cover ［ 14 ］ in the safty shield ［ 4 ］ is adjusted front and back position by pull bar ［ 15 ］, nut ［ 16 ］, and it is also fastening to slide in strip hole ［ 10 ］ by elasticity bolt ［ 17 ］.Rotation activity inner cover ［ 18 ］ can prolong that regulating tank ［ 11 ］ slides and rotates around motor ［ 1 ］ axle with elasticity bolt ［ 19 ］, and determines openings of sizes according to size of ground workpiece.Grinding wheel ［ 2 ］ below is provided with long-pending sand launder ［ 20 ］.With reference to accompanying drawing 1,2, hose ［ 6 ］ one ends are communicated with fixing outer protective cover ［ 7 ］ top dust exhausting hole ［ 12 ］, the other end is connected with dust catcher ［ 5 ］, dust catcher impeller ［ 21 ］ is fixed on grinding wheel drive mitor ［ 1 ］ axle head with jackscrew ［ 22 ］, the dust exhausting hole of dust catcher ［ 5 ］ is communicated with box base ［ 3 ］, the motor lower margin is fixed on the box base ［ 3 ］ with bolt ［ 24 ］, and casing is equipped with the overanxious net of air ［ 23 ］.
Claims (3)
1, a kind of new type of safe dust suction abrasive machine that is made of motor [1], grinding wheel [2] it is characterized in that safty shield [4] is connected by hose [6] with dust catcher [5], and dust catcher [5] is communicated with box style substructure [3].
2, new type of safe dust suction abrasive machine as claimed in claim 1, it is characterized in that, safty shield ［ 4 ］ is by fixedly outer protective cover ［ 7 ］, flexible interior protective cover ［ 14 ］, rotation activity inner cover ［ 18 ］ constitute, and protective cover ［ 14 ］ connects with fixing outer protective cover ［ 7 ］ by pull bar ［ 15 ］, nut ［ 16 ］ in flexible, and rotation activity inner cover ［ 18 ］ connects with the emery wheel axle head and passes through elasticity bolt ［ 19 ］ and locate.
3, new type of safe dust suction abrasive machine as claimed in claim 1 is characterized in that the impeller ［ 21 ］ of dust catcher ［ 5 ］ is affixed with the axle head of motor ［ 1 ］.
