Machine for machining exteriors in flat elements of revolution. Object of the invention

The present invention, as expressed in the statement of this specification, refers to a machine for the machining of flat elements of revolution, whose structure allows the external machining of cutting elements of revolution, quickly in a very short time reduced, while also allowing to mechanize those elements of revolution of any size and without problems of chip storage. Background of the invention

Currently there are many elements of revolution cutting that are used to perform agriculture, machining, etc., such as agricultural disks. These elements during their manufacturing process need to be machined at their outer edge to provide them with a fi le.

To date, the means to perform said machining are based on machining the fi le by turning. This turning can be done either by a parallel lathe or by using a vertical lathe.

The problem of using a parallel lathe lies in the loss of time involved in tying the disc to be machined on the plate for subsequent machining.

On the other hand, in the vertical lathe, in addition to the problem of mooring the disc on the plate, there is another problem related to the evacuation of the chips that are generated when machining the disc.

Said problem is that the chips remain deposited in the lower part of the lathe, said area being precisely where the motor in charge of moving the plate in which the disc to be machined is mounted is located. Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a machine for machining flat revolution cutting elements comprising a robust frame, on which a feeding device, a device is supported drive and a third machining device.

The feeding device comprises a rotating support coupled in a part of the frame, incorporating in such a rotating support lower follower plates provided with seating tools intended to support the support of the disks to be machined, contacting them on such seating tools by Your face below or below.

Each lower follower plate incorporates a hole and a vertically movable center in its center.

The driving device comprises an upper drive plate arranged above the lower follower plates and provided with a contact tool that will sit on the free face of the disk to be machined providing the necessary rotational movement to the disk to carry out its perimeter machining by means of a suitable tool incorporated in the machining device.

Thus, the rotary movement of the disk will be activated when the two facing plates, follower and drag, are pressing in contrast on the respective opposite faces of the disk, ensuring it is carried out by means of a hydraulic, pneumatic or electric actuator that moves up to the lower follower plate faced with the upper drag plate. In order to ensure the centering of the disc, centering centers associated with both upper and lower plates are incorporated.

The machining device comprises at least one radial unit that incorporates a respective tool to act on the peripheral area of the disk during its rotation to carry out the starting of material for machining.

Another possibility is that the machining device comprises two machining towers provided with different types of tools depending on the disc and / or type of machining to be performed.

With this arrangement described, the disc to be machined is placed centered on the respective lower follower plate, so that when it is facing and aligned concentrically with the upper drag plate, the lower follower plate is moved up until the disc contacts the contact tool of the upper drag plate, thus being trapped and holding the disc.

Once the disc has been fixed and its centering secured by means of the corresponding centers, the driving device is activated by rotating the upper drive plate and disc, and then activating the machining device whose tool is responsible for machining the disc on one or both sides of the same.

Next, in order to facilitate a better understanding of this specification and as an integral part thereof, some figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature. Brief description of the drawings

Considering the numbering adopted in the fi gures, the machine for the machining of flat revolution cutting elements, comprises a robust frame 23 which in principle supports a feeding device 1, a driving device 2 and a machining device 3 synchronized with each other, so that first the feeding device 1 acts, then the driving device 2 by rotating a disc 7 to be machined once immobilized and centered therein, the machining device 3 finally enters into operation to carry out the

3 EN 2362529A1 4

Perimeter banding of disc 7 during continuous rotation.

Starting from this premise, we will now describe each of the devices that make up the machine, as well as the relationship between them and their operation.

Thus, in the first place, the feeding device 1 is formed by a rotating support 4, which comprises diametrically opposed lower follower plates 5 and vertically movable with respect to the rotating support 4.

Said lower follower plates 5 have in their upper part seating tools 6 on which the discs 7 to be machined will rest. Said seat tools 6 are interchangeable depending on the size of the disk to be machined. Likewise, the lower follower plate 5 comprises in its central part a trunk-conical hole8 and a centering device 9 vertically movable on a rod 10, offering resistance to said downward vertical displacement an elastic element, such as a spring 11. Finally, the feeding device 1 has a hydraulic actuator 12 that incorporates a pusher 13 at its upper end with a conical trunk shape.

The driving device 2 is formed by an upper drive plate 14 which has in its lower part contact tools 15 whose function is to provide movement from the motor to the disk 7. Said contact tools 15 are interchangeable depending on the size of the disk to be machined. The upper drive plate 14 has in its central part a central guide drive 16 at the end of which there is a centering 17. Finally, indicate that the upper drive plate 14 is installed on a machining head 18 which rotates thanks to the use of the motor 19, also indicating that said upper drive plate 14 will contact, by means of the contact tools 15, on the upper face of the disk to transmit the rotation movement.

The machining device 3 is con fi gured by two machining units 20, which can be stems 21 with cutting blades 22 or towers 23 in which different types of tools are incorporated depending on the disc and / or the type of machining a perform.

Said machining units 20 can be moved both horizontally and vertically and are configured so that one of the units mechanizes the upper part, while the other mechanizes the lower part of the disc 7.

The operation of the machine for machining begins with the disc 7 being machined, located in the loading position, remaining centered by matching the central hole of the disc 7, with the centering 9 of the lower follower plate 5, so that a Once the disc 7 is placed in its loading position, a 180 ° rotation is made thanks to the rotating support 4, the lower follower plate 5 and the upper drive plate 14 being aligned. In that position the hydraulic actuator 12 vertically moves said lower follower plate 5 in relation to of the rotating support 4 by means of the thrust made by the pusher 13 of the hydraulic actuator 12 on the frustoconical hole 8.

The actuator 12 lifts the lower follower plate 5 until the disc 7 is pinched between the seating tool 6 and the contact tool 15 belonging respectively to the lower follower plate 5 and upper drive plate 14.

Once the disc 7 is fixed by the tools 6 and 15, the centering 17 of the driving device 2 descends, thanks to the actuation of a central guide 16 until the centering 17 is secured to the disc 7, moving that movement down to the pusher 9.

Subsequently, the motor 19 drives the machining head 18 by rotating the upper drive plate 14 and therefore the disk 7, to finally machine the fi lter of the disk 7 thanks to the machining units 20.

Once the disc 7 is machined, the rotating support 4 will rotate 180 ° to introduce a new disc to be machined, while the one that is already machined is discharged.

In this way, time and chip storage are optimized to a minimum, since there are hardly any elements at the bottom of the machine.

On the other hand, it should be noted that the centers 9 and 17 are interchangeable, so that they can be adapted to the central and / or peripheral holes of the disc to be machined.
