Description

CLAMP TYPE CLAMPING DEVICE

TECHNICAL FIELD The present invention relates to the field of clamping devices, generally designated by the term "clamp-joint". Such a clamping device thus generally comprises a rectilinear slide for defining a longitudinal direction in which a clamping force can be exerted. Such a clamping device thus makes it possible to hold two elements in position relative to one another. It then makes it possible temporarily to join two disjoint elements in connection with embedding.

PRIOR ART In general, clamping devices are known in which an pressing assembly is provided with a bore. This bore is then traversed by a slide, to form a slide connection with this slide.

To immobilize two disjoint elements, two sets are then brought closer to each other, then a clamping means is actuated to exert the clamping force.

However, this type of clamping device has many disadvantages, and in particular they do not allow to insert an additional pressing assembly between two pairs of pressing assemblies already cooperating with a slide or at one end. slide with a stop.

Thus, one of the aims of the invention is to provide a very flexible clamping device, making it possible to add or remove removable pressing assemblies in a simple manner, and this, whatever the configuration of the device. Indeed, the clamping device can make it possible to add intermediate pressing assemblies, for example between two other pairs of pressing assemblies. SUMMARY OF THE INVENTION

The invention therefore relates to a tightening device of the clamp type enabling a tightening force to be exerted in a longitudinal direction D. In addition, such a clamping device comprises:

• a rectilinear slide oriented parallel to said longitudinal direction;

At least one pressing assembly, said pressing assembly comprising a bore traversed by said slide and forming a slide connection with said slide.

According to the invention, this clamping device is characterized in that the bore comprises a pivoting portion movable in rotation about an axis parallel to the longitudinal direction D, the pivoting portion being movable between a closed position, in which the slide is trapped in the bore, and an open position in which the pressing assembly is removable by moving in translation in a radial direction perpendicular to the longitudinal direction D.

In other words, the pivoting portion of the bore makes it possible to make at least one pressing assembly of the rectilinear slideway removable. It is thus sufficient to open the pivoting portion to allow the radial displacement of the pressing assembly relative to the slide. Such an arrangement makes it possible in particular to add or remove an pressing assembly that would be positioned between two other pairs of remote pressing assemblies. It is then no longer necessary to disassemble one or more pressing assemblies already in place on the slide and / or in the process of exerting a tightening force.

Advantageously, the rectilinear slide may comprise an X-shaped cross section. In other words, the section of the rectilinear slide has four branches angularly distributed at 90 degrees to form an X about the longitudinal direction D. Such a shape of cross section of this rectilinear slide then allows to give the clamping device a high rigidity in torsion and flexion in particular. In practice, the pivoting portion may comprise a recess for cooperating with one of the branches of the X-shaped cross section of the rectilinear slide. In this way, the notch has a shape complementary to one of the branches forming the rectilinear slide. Such an indentation then makes it possible to eliminate a degree of freedom in rotation between the rectilinear slide and the pressing assembly equipped with such a pivoting portion. Furthermore, the symmetrical X shape of the rectilinear slide allows to position the pressing assembly in four distinct angular orientations and arranged at 90 degrees relative to each other.

Thus, it is possible to change the angular orientation of an pressing assembly relative to the straight slider only by positioning the pivoting portion in an open position, and then rotating the bore of the pressing assembly around the straight slider. .

According to a particular embodiment, the device may comprise a removable locking pin for securing a free end of the pivoting portion with a fixed portion of the pressing assembly.

Thus, the removable locking pin allows to maintain in its closed position the pivoting portion with the fixed portion of the pressing assembly. Such a locking pin may in particular be in the form of an elongated cylindrical member, whose orientation may be parallel to that of the rectilinear slide.

Advantageously, the locking pin can cooperate with, on the one hand, at least one orifice of the pivoting portion and, on the other hand, a housing of the fixed portion of the pressing assembly.

In this case, when the orifice of the pivoting portion and the housing of the fixed portion are arranged facing one another, the locking pin can be inserted to form the connection between the flush portion and the fixed portion. According to different variants of the invention, the pressing assemblies can be indifferently movable or fixed in translation relative to the rectilinear slide.

Thus, according to a first embodiment, the pressing assembly can be movable in translation along the rectilinear slide.

In other words, the pressing assembly can move along the slide to achieve, for example, clamping forces between two elements of variable thickness. According to a second embodiment, the pressing assembly can be fixed along the rectilinear slide.

In this way, the pressing assembly is stationary relative to the rectilinear slide and is associated with another pressing element to make it possible to perform a clamping force between parts of the same thickness, or it can also be associated with another pressing assembly which is movable in translation to perform clamping forces between two elements of varying thicknesses.

SUMMARY DESCRIPTION OF THE FIGURES

The manner of carrying out the invention as well as the advantages which result therefrom will be apparent from the description of the embodiment which follows, given by way of indication but not by way of limitation, with reference to FIGS. perspective, the different assembly steps of a device according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

As already mentioned, the invention relates to a clamping device type "clamp" to exert a clamping force in a longitudinal direction.

As shown in Figure 1, the longitudinal direction D is formed by the direction in which extends longitudinally a slide 2. As shown, such a slide 2 may have an X-shaped cross section having four branches 8 oriented according to an angle of 90 degrees to each other. Such a clamping device 1 also comprises at least one pressing assembly 3 intended to exert the clamping force in the longitudinal direction D. Such an assembly 3 also includes a bore 4 inside which the slide 2 is intended to be arranged.

As shown, such a bore 4 is formed on the one hand by a fixed portion of the pressing assembly 3, and by a pivoting portion 5 rotatable about an axis 6 parallel to the longitudinal direction D. Moreover, the movable portion 5 may also have a recess 7 intended to cooperate with one of the branches 8 of the rectilinear slide 2.

As shown in FIG. 2, such an arrangement makes it possible to position the pressing assembly 3 on the slide 2 by performing a radial translation movement in a direction perpendicular to the longitudinal direction D. Once the slide 2 has been in contact with the portion fixed 11 of the pressing assembly 3, is then rotated the pivoting portion 5 so as to match a free end 12 facing a housing 13 formed in the fixed portion 11. In addition, as long as the portion pivoting 5 is arranged in the open position, it is possible to rotate the pressing assembly 3 about an axis of rotation coincides with the longitudinal direction D. Such an arrangement then makes it possible to vary the angular orientation of the pressing assembly 3 with respect to the rectilinear slide 2.

Moreover, and as shown, the free end 10 of the pivoting portion 5 comprises at least one orifice 12 intended to come opposite the housing 13 of the fixed portion 11.

This step is then explained in FIG. 3, in which is represented a releasable locking pin 9 which can move in a translation movement parallel to the longitudinal direction D. Furthermore and as shown in Figure 4, once the locking pin 9 inserted inside the orifice 12 and the housing 13, the pressing assembly 3 is then secured to the rectilinear slide 2. In addition , the notch 7 formed in the pivoting portion 5 avoids any relative rotational movement between the pressing assembly 3 and the rectilinear slide 2.

As shown in Figure 5, to exert the clamping force in the longitudinal direction D, the lever is folded down, which has the effect of translational movement of the jaw 14 in the longitudinal direction D.

Finally, if it is desired to stop the clamping force, it is necessary to actuate a trigger 16 arranged at the lever 15. The actuation of the trigger 16 thus releases the jaw 14 to no longer exercise clamping force. It follows from the foregoing that a device according to the invention has many advantages, and in particular:

It makes it possible to make the fixed and / or mobile pressing assemblies removable from such a clamping device;

It makes it possible to add, remove or modify the orientation of these pressing assemblies without having to dismount one of the assemblies already positioned on the slide or to disassemble a stop element arranged at one of the ends of the slide. slide;

It thus makes it possible to add pressing assemblies while maintaining a clamping force between two other pressing assemblies of the device;

· It is suitable for any operating device such as notching, ratchet, screw or the like associated with a piston or a spring in particular;

• It is suitable for any type of implementation, including manual implementation, pneumatic, hydraulic, electrical to exert the clamping force.
