Flap wheel
Technical field
The utility model relates to the machining tool of a kind of grinding, polishing, especially a kind of flap wheel.
Background technology
Flap wheel, in industrial production, occupies important effect.Wherein, be widely used in the processing of industrial production product, mainly play sanding and polishing etc., purposes is very wide and use very convenient, the miniature page wheel can be installed on portable grinder, electric angle grinder, special pneumatic or electric tool, complex region to the workpiece of various shapes carries out attrition process, and as dish-like or pull out type page wheel, can being installed on electric angle grinder, that curved or spill workpiece are carried out to polishing is especially suitable; Fillet inwall, workpiece interior angle, groove, gap and hole are carried out to polishing, and deburring burr and other polishing are particularly suitable.
But the Proportionality design between the pallet external diameter of traditional flap wheel and annular this body diameter of flap wheel is unreasonable, easily cause the incomplete use of flap wheel, the utilization rate of flap wheel is low, form very large waste, production cost is high, traditional flap wheel is little with the contact area that is ground object in addition, and grinding efficiency is low.
The utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides a kind of and can greatly improve the utilization rate of flap wheel, thereby reduce production costs, and can also greatly improve the grinding efficiency of flap wheel, thus the flap wheel of obviously increasing work efficiency.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of flap wheel is provided, comprise pallet, be bonded in successively the annular flap wheel body formed on pallet by some emery cloth sheets, described pallet and annular flap wheel body are bonded as one, the external diameter of described pallet is 90:115~100:125 with the ratio of the external diameter of annular flap wheel body, flap wheel and the contact area that is ground object are significantly increased, flap wheel almost can be used fully, can effectively improve the utilization rate of flap wheel, production cost is low, and grinding efficiency is high.
As further improvement of the utility model, be equiped with the axle sleeve be fixedly connected with pallet in described rotating shaft fixing hole, be convenient to flap wheel is connected, extend the service life of flap wheel.
The beneficial effect of flap wheel described in the utility model is: by the ratio between the pallet external diameter to flap wheel and annular this body diameter of flap wheel, carry out appropriate design, thereby flap wheel almost can be used fully, the utilization rate of flap wheel can improve nearly one times, the utilization rate of flap wheel is high, avoid waste, production cost is low, in addition, flap wheel significantly increases with the contact area that is ground object, has greatly improved the grinding efficiency of flap wheel.
Below in conjunction with drawings and Examples, flap wheel described in the utility model is described further.
The accompanying drawing explanation
Fig. 1 is the structural representation of flap wheel described in the utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below the preferred example of flap wheel described in the utility model, therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, Fig. 2, a kind of flap wheel is provided, comprise pallet 1, be bonded in successively the annular flap wheel body 3 formed on pallet 1 by some emery cloth sheets 2, described pallet 1 is bonded as one with annular flap wheel body 3, the external diameter of described pallet 1 is 90:115~100:125 with the ratio of the external diameter of annular flap wheel body 3, adopt this ratio, can make flap wheel and the contact area that is ground object significantly increase, flap wheel almost can be used fully, can effectively improve the utilization rate of flap wheel, production cost is low, and grinding efficiency is high.
The center of described pallet 1 is provided with rotating shaft fixing hole 4, and has bowl structure projection 5.
Be equiped with the axle sleeve 6 be fixedly connected with pallet 1 in described rotating shaft fixing hole 4, axle sleeve adopts metal material processing to form, and is convenient to flap wheel is connected, and extends the service life of flap wheel.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
