Abstract
The present invention relates to a structure for fixing grinding papers applied to a wheel paper of a circular plate shape, which is coupled to a rotary shaft of a hand-held grinder to support and rotate the grinding papers. More particularly, the present invention relates to a structure for fixing grinding papers wherein a support member is integrally disposed upright at one side of an insertion hole of a wheel paper into which grinding papers are inserted, thus supporting the sides of the grinding papers when the wheel paper is rotated, whereby the support strength of the grinding papers is improved to increase the contact force when the grinding papers are rubbing against a subject to be grinded, a working time is shortened and work efficiency is improved through improved grinding efficiency, the tips of the grinding papers that are difficult to use due to the bending property can be used through a reinforced strength of the grinding papers, the whole surface of the grinding papers can be thus used, usage efficiency of the grinding papers is maximized and the life of the grinding papers can be extended.
Description
Background technology
The invention belongs to the abrasive machine technical field, specifically a kind ofly combine, support abrasive cloth and make the fixture construction of applied abrasive cloth in the disc emery wheel paper of its rotation with the rotating shaft of portable abrasive machine.
Technical field
Known portable abrasive machine with the fixture construction of the abrasive cloth that is employed in the emery wheel paper (20) is, as shown in Figure 4, there is the hang plate (21) of fixed motor (M), rotating shaft (S) centre, this hang plate (21) has the folder hole (22) of fixing many overlapping abrasive cloths that form (23) of a plurality of insertions, and folder hole (22) is equidistant arrangement.
But, as shown in Figure 5, above-mentioned structure just merely has the effect that utilizes folder hole (22) and cement fixed support abrasive cloth (21) fixed end part, the support zone of abrasive cloth is limited in narrow and small fixed position, and bias toward a side, so can not to abrasive cloth itself increase long to support strength, so, as shown in Figure 2, when utilizing abrasive cloth to grind object, for increasing frictional force, even add pressure contact force slightly, also can be as shown in Figure 5, abrasive cloth is that benchmark is crooked easily with the fixed position, make fore-end perk in grinding object of abrasive cloth, thereby can not bring into play abrasive action, if just utilize so and add pressure contact force accordingly, the not only inefficiency of Yan Moing, and abrasive cloth also can't all be used, thereby shortens the service life of abrasive cloth, finally cause the waste problem that frequently to change, if for the fore-end that uses abrasive cloth reduces contact force, so, abrasive power will reduce, cause the prolongation of working time, will cause the reduction of operating efficiency thus.
Summary of the invention
The objective of the invention is when grinding, can improve the abrasive cloth fixture construction of the portable abrasive machine of abrasive cloth support strength with emery wheel paper.
The object of the present invention is achieved like this: it includes fixed motor, hang plate, folder hole, abrasive cloth, rotating shaft is characterized in that: central authorities have the stator of tightening the hole, to tighten the rotating shaft of fixed motor, the acclivitous toward the outer side hang plate of integral body is arranged on this stator, the folder hole of fixing many overlapping abrasive cloths that form of a plurality of insertions is arranged on the above-mentioned hang plate, folder hole is equidistant arrangement.
When the rotation of above-mentioned abrasive cloth, with abrasive cloth by and grind the object friction and the marginal portion of crooked corresponding above-mentioned each folder hole of a side, integral body is put into support chip.
The invention reside in the support strength that improves abrasive cloth, contact force when increasing with the friction of grinding object, shorten working hours and increase work efficiency by improving grinding efficiency, simultaneously also will be by increasing the support strength of abrasive cloth, make easy bending, use the lowermost end part of difficulty also can use, make abrasive cloth obtain full use, thereby farthest improve the service efficiency of abrasive cloth, and prolong the abrasive cloth fixture construction of the portable abrasive machine in abrasive cloth service life with emery wheel paper.For achieving the above object, the present invention makes the support chip integral body of certain altitude stand on the marginal portion of folder hole one side of the emery wheel paper that accompanies abrasive cloth, makes its side of supporting abrasive cloth when emery wheel paper rotates, thereby improves the support strength of abrasive cloth.Describe formation of the present invention in detail below by accompanying drawing.
Effect of the present invention is, the marginal portion of folder hole one side of the emery wheel paper by support chip integral body being stood on accompany abrasive cloth, make it when emery wheel paper rotates, support the side of abrasive cloth, thereby improve the support strength of abrasive cloth, contact force when increasing with the friction of grinding object is shortened working hours and is increased work efficiency by improving grinding efficiency.Simultaneously,, make easy bending, use the lowermost end part of difficulty also can use, make abrasive cloth obtain full use, thereby farthest improve the service efficiency of abrasive cloth, and prolong the service life of abrasive cloth by increasing the support strength of abrasive cloth.

To be described in further detail invention by example below, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
The specific embodiment
By accompanying drawing 1, Fig. 2 and shown in Figure 3, formation of the present invention is, central authorities have the stator (1) of tightening hole (2), and the rotating shaft (S) to tighten fixed motor (M) has the acclivitous toward the outer side hang plate of integral body (3) on this stator (1).
The folder hole (5) of fixing many overlapping abrasive cloths that form (4) of a plurality of insertions is arranged on the above-mentioned hang plate (3), and folder hole (5) is equidistant arrangement.
In a lateral edge portions of above-mentioned folder hole (5), more particularly, be that the marginal portion of abrasive cloth (4) curved side forms support chip (10) with upright state when abrasive cloth (4) spin finishing, it highly probably should be suitable with the width of folder hole (5).
Simultaneously, for increasing the support strength of support chip (10), can put into the enhancing rib in the inside of support chip (10).
Annotate: unaccounted symbol in the accompanying drawing
(G) be to grind object; (A) expression bonding part.
The effect of the present invention of above-mentioned formation is, after motor (M) energising, the rotating shaft (S) of motor (M) is rotation at a high speed, therefore, the abrasive cloth (4) of coupled emery wheel paper also begins rotation, and as shown in Figure 2, make this abrasive cloth (4) to lopsidedness, make it and grind object (G) and combine closely, so, the end portion of abrasive cloth (4), begins to grind grinding object (G) with slight curving state rotation along the direction of rotation of emery wheel paper simultaneously, at this moment, owing to be the curved side of supporting abrasive cloth (4) by support chip (10), so the bending of abrasive cloth (4) is that the end with support chip (10) is that benchmark forms in fact.
Therefore, according to the intensity identical materials, length is long more, the characteristics more little to the drag of bending, end at abrasive cloth shortens the crooked length that takes place between line, can reach the effect of the support strength of strengthening self, so, apply and in the past identical pressure, by the support strength that is reinforced, can reduce crooked degree, so as shown in Figure 3, can contact with grinding object (G) from the end of abrasive cloth (4), all areas are all effectively utilized.
