Description

Machine for outdoor machining in flat elements of revolution.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a machine for the machining of flat elements of revolution, whose structure allows to realize the external mechanized of elements of cut of revolution, quickly in a very short time, while also allows machining those elements of revolution of any Size and without chip storage problems.

Background of the invention

Currently there are many cutting elements of revolution used to perform agricultural work, machining, etc., such as agricultural disks. To these elements during its manufacturing process it is necessary mechanize them on their outer edge to give them an edge.

To date, the means to carry out said Machining are based on machining the cutting edge 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 that involves tying the disk to be machined in the plate for later machining.

Instead, on 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 by Mechanize the disk.

This problem is that the chips are they are deposited in the lower part of the lathe, said area being where the engine responsible for moving is located precisely the plate on which the disc to be machined is mounted.

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 elements of revolution cut comprising a robust frame, on the that a power device is supported, a driving device and a third machining device.

The feeding device comprises a swivel mount coupled to a part of the frame, incorporating on such turntable, lower follower plates provided of seating tools intended to support the support of discs to be machined, contacting them about such tools seat down or down face.

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

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

Thus, the rotating movement of the disk is will activate when the two facing plates, follower and drag, are pressing in contrast on the respective faces opposite of the disc, thus ensuring its fixation and centering.

The axial fixation and immobilization of the disc is carried out by means of a hydraulic, pneumatic or electric that moves up to the lower follower plate faced with the top drag plate. To ensure the centering of the disc are incorporated some centers associated to the Two plates, upper and lower.

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

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

With this arrangement described, the disk a machining is placed centered on the respective follower plate lower, so that it is facing and aligned concentrically with the upper drag plate, it moves up the bottom follower plate until the disc contacts with the contact tool of the upper drag plate, thus remaining imprisoned and held 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.

Then, to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the machine for machining flat cutting elements of revolution, it comprises a robust frame 23 that supports in principle a feeding device 1, a driving device 2 and a machining device 3 synchronized with each other, so that the power device 1 first acts, then the driving device 2 spinning a disc 7 to be machined once immobilized and centered the same, coming into operation finally the machining device 3 to carry out the perimeter machining of disc 7 during continuous rotation.

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

So, first of all, the device feed 1 is formed by a rotating support 4, which it comprises a few lower 5 diametrically follower plates opposite and vertically movable with respect to the rotating support Four.

Said lower followers plates 5 possess in its upper part a seating tool 6 on which they will rest 7 disks to be machined. Said seating tools 6 are interchangeable depending on the size of the disk to be machined. Also, the lower follower plate 5 comprises in its central part a trunk-conical hole 8 and a centering 9 vertically movable on a rod 10, offering a resistance to said downward vertical displacement an element elastic, such as a spring 11. Finally the device supply 1 has a hydraulic actuator 12 that carries incorporated a pusher 13 at its top shaped end conical trunk.

The driving device 2 is formed by an upper drag plate 14 which has in its lower part about contact tools 15 whose function is to provide movement from the motor to the disk 7. Such contact tools 15 are interchangeable depending on the size of the disk to be machined. He upper drag 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 drag plate 14 is It is installed on a machining head 18 which rotates thanks to the use of engine 19, also pointing out that the aforementioned upper drag plate 14 will contact, through the contact tools 15, on the top face of the disc for transmit the movement of the turn.

The machining device 3 is located configured by two machining units 20, which can be stems 21 with cutting blades 22 or towers 23 in which incorporate different types of tools depending on the disc and / or of the type of machining to perform.

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

The operation of the machine for machining starts with disc 7 being machined, located in the loading position, staying centered by matching the central hole of disc 7, with centering 9 of the follower plate bottom 5, so that once the disc 7 is in position loading, a 180º turn is made thanks to the rotating support 4 the lower follower plate 5 and the plate of alignment being aligned upper drive 14. In that position the hydraulic actuator 12 vertically displaces said lower follower plate 5 with respect of the rotating support 4 by means of the thrust made by the pusher 13 of the hydraulic actuator 12 over the conical bore 8.

The actuator 12 raises the follower plate bottom 5 until disc 7 is trapped between the tool seat 6 and contact tool 15 belonging respectively to lower follower plate 5 and upper drive plate 14.

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

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

Once the disk 7 has been machined, the support Rotary 4 will rotate 180º to introduce a new disk to be machined, while the one that is already mechanized is unloaded.

This optimizes time and chip storage to a minimum, since at the bottom of the machine there are hardly any elements.

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 that the disc has mechanize.
