Abstract

The utility model provides an emery cloth ring wheel which includes a drive wheel and a grinding wheel ring; the drive wheel comprises an expansion wheel which pierces a rubber material by a drive shaft; the wheel surface of the expansion wheel is provided with a plurality of parabola-type troughs to form a plurality of support pieces; the grinding wheel ring is formed by that one surface of a cirque is attached with a plurality of emery cloths which are arranged presenting inclined insertion and cascading type; in this way, the emery cloth ring wheel is formed by the grinding wheel ring and the cirque sleeved on the exterior of the expansion wheel of the drive wheel; by adopting the emery cloth arrangement of the grinding wheel ring, the utility model reaches the effects of high heat dissipation effect, increasing grinding area, gradually providing new emery cloth grinding and reducing grinding vibration, etc.

Description

Abrasive endless wheel

Technical field

The utility model provides a kind of Abrasive endless wheel, especially refer to a kind of can being installed in arbitrarily in the rotating shaft of hand-held or fixed electric grinder, in order to high speed rotary and at surface of the work polish, paint removal, rust cleaning, chamfering or remove the Abrasive endless wheel of work such as burr.

Background technology

Common Abrasive endless wheel structure (as Fig. 5 and shown in Figure 6) in the prior art, generally include a driving wheel 10 and an emery cloth ring 20, this driving wheel 10 is made of the expansion wheel 102 that a driving shaft 101 is arranged in a rubber material, these expansion wheel 102 wheel faces are provided with several parabolic groove 103, prop up sheet 104 to form several pieces; And this emery cloth ring 20 is to constitute in an annulus 201 peripheral emery cloths 202 that coat, make emery cloth ring 20 be sheathed on expansion wheel 102 peripheries of driving wheel 10 by this, promptly form when driving wheel 10 revolution, to utilize and prop up sheet 104 and expand and prop up emery cloth ring 20 rotating Abrasive endless wheels, to carry out surface grinding, paint removal, rust cleaning, chamfering at general workpiece or to remove work such as burr.

As mentioned above, conventional emery cloth ring 20 is coated with an emery cloth 202 in an annulus 201 peripheries, therefore its emery cloth 202 can with milling area to only limit to the anchor ring of annulus 201 long-pending, the grinding-material that emery cloth 202 of event can be used is limited, and emery cloth 202 wears away very easily fast, the machine that must stop upgrades, and causes grinding work smooth and easy inadequately; Secondly, this emery cloth 202 is close to annulus 201 peripheries of hard, very easily produces vibrations because of very stiff and demanding when the grinding hard workpiece, and then the smooth effect of influence grinding; In addition, because of the emery cloth 202 of routine is to continue to grind when the high speed rotary,,, also may directly grind and scald the operating personnel because of the operating personnel often hands metal works except that burning (for example woodwork) workpiece so friction produces high temperature easily.

Summary of the invention

The purpose of this utility model is to provide a kind of Abrasive endless wheel, by improving the emery cloth setting of emery wheel ring, reaching increases the amount that emery wheel ring wheel has grinding-material, but improves the purpose of the milling time of emery wheel ring wheel, but efficiently radiates heat makes the smooth and easy safety of grinding operation simultaneously.

The emery wheel ring wheel that the utility model provides, it comprises a driving wheel and an emery wheel ring, described driving wheel is for being installed in hand-held or fixed electric grinder arbitrarily to drive the rotating member of emery wheel ring, it is characterized in that: the emery wheel ring, constitute by an annulus and several pieces emery cloths, several pieces are the oblique cutting stacked arrangement around the annulus this emery cloth, and each emery cloth root is adhered on the annulus, make the emery wheel ring be sheathed on its annulus that the expansion wheel of driving wheel is outer forms a kind of Abrasive endless wheel by this.

Above-mentioned Abrasive endless wheel, its driving wheel comprise that the expansion wheel that is arranged in a rubber material by a driving shaft constitutes, and the wheel face of this expansion wheel is provided with several parabolic groove, is formed with several pieces and props up sheet around it.

The utility model is to make above-mentioned emery wheel ring be sheathed on a kind of Abrasive endless wheel of the outer composition of expansion wheel of described driving wheel with its annulus, utilize the emery cloth of this emery wheel ring to arrange, because of its emery cloth upper end has suitable elasticity activity space, so can reach radiating effect height, abradant surface increase, can progressively provide new emery cloth to grind, and reduce effects such as grinding vibrations.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing, but do not limit practical range of the present utility model.

As shown in Figures 1 and 2, Abrasive endless wheel of the present utility model, it is made up of a driving wheel 1 and an emery wheel ring 2, thus loading, unloading are ground on hand-held or fixed electric grinder arbitrarily, wherein:

Driving wheel 1 (as shown in Figure 1), it is for can be installed in hand-held or fixed electric grinder arbitrarily and to drive emery wheel ring 2 rotating members, the driving shaft 11 that is arranged in this expansion wheel 12 by the expansion wheel 12 and of a rubber material is constituted, the wheel face of this expansion wheel 12 is provided with several parabolic groove 121, be formed with several pieces around it and prop up sheet 122, can be when being driven high speed rotary swell by centrifugal force and fixing and drive following emery wheel ring 2.

Emery wheel ring 2 (as shown in Figures 3 and 4), it is to be driven wheel 1 to drive revolution with this grinding-material that grinds at workpiece, it is made of an annulus 21 and several pieces emery cloths 22, this annulus 21 can be the made ring body of paper wood, steel or rubber, being the oblique cutting stacked arrangement around this annulus 21 has several pieces emery cloths 22, and each emery cloth 22 root is adhered on this annulus 21.

By this, please refer to Fig. 2 to shown in Figure 4, emery wheel ring 2 is sheathed on expansion wheel 12 peripheries of driving wheel 1 with its annulus 21, promptly forms Abrasive endless wheel of the present utility model.

Abrasive endless wheel of the present utility model, especially be provided with several pieces emery cloth 22 structure arranged designs around being set forth in emery wheel ring 2 on, promptly around an annulus 21, be provided with a considerable amount of emery cloths 22, this emery wheel ring 2 spendable grinding-materials have been increased, so time and the quantity that can promote grinding work avoid often shutting down the emery wheel ring 2 more to renew; Secondly, emery cloth 22 of the present utility model is several pieces shape oblique cuttings and is laminated in around the annulus 21, it is not each emery cloth 22 to be used up when grinding work-piece at once, and can be along with the abrasion of emery cloth 22 front end faces, progressive provides new part to grind with the lower end again, so can improve the shortcoming that conventional ring-type emery cloth 202 just is worn away at once, promote each emery wheel ring 2 triturable time and quantity.

In addition, the arrangement architecture of several pieces emery cloths 22 around the emery wheel ring 2 of the present utility model, be to be adhered to around the annulus 21 with its root, so emery cloth 22 upper ends have suitable elasticity activity space, and can be when grinding hard workpiece, avoid producing very stiff and demanding vibrations situation, can reach the effect of the smooth grinding of surface of the work with workpiece.Moreover, the utility model is to be adhered to annulus 21 with several pieces emery cloths 22 to constitute emery wheel ring 2 on every side, these emery cloth 22 upper ends have suitable elasticity activity space, so when grinding, can produce radiating effect, avoid continuing friction and produce high temperature, further can prevent to burn workpiece or scald the operating personnel because of the often hand-held metal works of operating personnel directly grinds.

In sum, the utility model should meet the application condition of utility model patent, so earnestly ask approval.
