It allows to work on the piece to grind of horizontal or vertical way.

Description

Grinding head.

The present invention relates to a head of grinding, which can be used in any grinding machine linear, rotary and / or robotic cell.

Background of the invention

The grinding machines currently known They comprise one or more grinding heads. For example, the grinding machines can be linear, rotary or cell robotic

The inconvenience of the machines currently known is that the head is placed only in a position, horizontal or vertical, for grinding on the piece to grind.

Therefore, at present, to grind the piece horizontally and vertically are necessary two Heads

Description of the invention

With the grinding head of the invention, They manage to solve the aforementioned problems, presenting other advantages to be described.

The grinding head of the present invention comprises a grinding band, and is characterized by the fact that it comprises a first and / or a second turning device of said grinding band, so that said grinding head can rotate, by said first rotation device, around its longitudinal axis and / or placed in any position between a substantially horizontal position and a substantially vertical position, by means of said second device of
turn.

Thanks to this feature, with the head of The present invention can be worked on the piece to be ground horizontally or vertically. In addition, it allows to place the band of the head with respect to the pieces to grind with more options and more easily, which makes the grinding program more simple. Specifically, it allows grinding vertical, shaped faces concave, inclined, convex or vertical.

Advantageously, said rotation of the head of frosted covers approximately 90º, between a position substantially horizontal and substantially vertical position of the grinding band.

According to a preferred embodiment, said grinding device of the grinding band comprises a disc rotating around a central axis, said disk comprising rotating a projection that defines two stop surfaces, entering said stop surfaces in their positions substantially horizontally and substantially vertical in contact with each other stop elements.

In order to guarantee the perfect head positioning, the position of said stop elements It is adjustable.

In addition, said disk preferably comprises a groove inside which houses a pin integral to a drive for rotation of said disk.

According to a preferred embodiment, said element of driving the rotation of said disk is a cylinder Dynamic fluid

Advantageously, said slot is placed in a diametrically opposite position with respect to said surfaces of stop, top, maximum as a noun, top as an adverb.

Brief description of the drawings

For a better understanding of how much has been exposed Some drawings are accompanied in which, schematically and only to title of non-limiting example, a practical case of realization.

Figure 1 is a perspective view of the grinding head of the present invention;

Figure 2 is a sectional view of the first turning device in its horizontal position;

Figure 3 is a sectional view of the second turning device in its vertical position;

Figures 4 to 8 are views of the possible head positions of the present invention, for grinding of different types of faces.

Description of a preferred embodiment

In figure 1 a head of grinding according to the present invention, identified in general by numerical reference 1.

Said grinding head 1 comprises an axis longitudinal 2 and a grinding band 3. The grinding head 1 also includes other elements, such as an engine of grinding belt drive 3, which will not be described, since that are well known to any expert in the field and They are not part of the present invention.

According to the embodiment shown, this band of frosted 3 comprises a first turning device 20 and a second turning element 21.

The first turning device 20 rotates the grinding head 1 around its longitudinal axis 2, while that the second turning device 21 allows to rotate the head of frosted between a substantially horizontal position and a substantially vertical position. These positions will be described. later in relation to figures 4 to 8.

In figures 2 and 3 it has been represented in first turning device 20 in sectioned in its two positions extreme

In the case of the second turning device 21, the rotation is driven by a gearmotor, indicated by numerical reference 22 in figure 1, although it should be indicated that It could be operated by any suitable means.

The first turning device 20 comprises a rotating disk 4 around a central axis 8. Said disk 4 is in solidarity with said longitudinal element 2, and consequently said grinding band 3, and comprises a projection 5 defining a pair of butt surfaces, which define a right angle to each other, and an elongated groove 6 located in a diametrically opposite position with respect to said stop surfaces 5.

Said stop surfaces 5 come into contact with two stop elements 7 when the grinding band 3 is in its vertical position or in its horizontal position. To guarantee the perfect positioning of said grinding band 3, said stopper elements 7 are adjustable, so that it can be adjusted your position

The rotation drive of said disk 4, and in consequence of the grinding band 3, it is preferably performed by means of a pneumatic cylinder 9, although it could be operated by Any suitable means.

Said cylinder 9 comprises at the end of its rod a pin 10 that is housed inside said slot elongated 6. In this way, pin 10 exerts pressure on the slot 6 that causes the disk 4 to rotate, and consequently of the grinding band 3, in one direction or another, depending on whether the cylinder rod 9 extends or contracts.

In figures 4 to 8 it has been represented in grinding head in different positions that you can adopt thanks to the presence of said turning devices.

Figure 4 shows the head of frosted 1 in the same position as shown in the figure 1. This position is suitable for grinding faces vertical

In Figure 5, the first turning device 20 causes rotation of head 1 around its longitudinal axis 90º. This position is used for grinding shaped faces. concave and convex.

In figure 6 the head 1 is shown rotated about 45º with respect to the horizontal. This turn is done by the second turning device 21. It should be noted that the head 1 can be placed in any position between its position horizontal and its vertical position. This position is used for the grinding of inclined faces from 0º to 90º.

In figure 7, the head 1 is in its position completely vertical, that is, rotated 90º from the position represented in figure 4. This position is suitable for the Frosted horizontal faces.

Finally, in figure 8 the head 1 that has rotated 90º around its longitudinal axis with respect to the position represented in figure 7. This position is also used for grinding horizontal faces.

It should be noted that the grinding head of The present invention can be used in any machine of linear, rotary and / or robotic cell grinding.

It should also be noted that the rotations and turns indicated in this description are simply indicative, since rotations and turns could be described with Any suitable value.

Although reference has been made to a Concrete embodiment of the invention is evident to an expert in the matter that the grinding head described is susceptible to numerous variations and modifications, and that all the details mentioned can be substituted by others technically equivalent, without departing from the scope of protection defined by the attached claims.
