Definitions
- the known solutions for ensuring these functions all have common characteristics.
- the tool is guided on cylindrical surfaces, either of the same diameters or of different diameters.
- the rotation stop and the axial retention of the tool are effected by one or more removable keys, cylindrical or flat, as described in document FR-A-2248914.
- the present invention provides a holding device which overcomes these drawbacks.
- the device according to the invention of the type in which the tool is arranged coaxially with a striking piston, is mounted to slide, with the interposition of upper and lower guide means, in a front guide, and is limited in its stroke, respectively, upwards, by an abutment face of the guide, and, downwards, by at least one transverse key, disposed between the guide means and also forming an axial retaining means for this tool in the guide , is characterized in that, on the one hand, the upper guide means, situated on the side of the striking face of the piston, comprises a guide zone, the guide curve of which includes inflection points forming angles of separation of facets, this zone cooperating with a zone of complementary section formed, at least locally, on the tool, to wedge the latter in rotation and, on the other hand, the lower guide means is constituted by a cooperating cylindrical sleeve nt with a tool area, also cylindrical.
- the tool 5 has, in the upper part, a polygonal section, and below the notches 8, a cylindrical section.
- the lower guide means 4 are constituted by a bush having a cylindrical bore.
- the setting in rotation of the tool 5 relative to the front guide 2 is ensured by the upper guide means 3 which comprises a guide zone, the guiding curve of which includes inflection points forming angles 10 of separation between facets 12, that is, has non-circular, polygonal, or pseudopolygonal shapes.
- the tool 5 has a square cross section and cooperates with sockets 3a and 4a, constituting the guide means, upper and lower, also having an axial bore of square section.
- the tool 5b has two flats 14 constituting the facets 12 and cooperate with a socket 3c of similar internal section.
- the tool 5c is provided, in its flats 14, with two concave facets 15. This tool cooperates with a bore of the same section as it formed in a 3d socket carried by the front guide 2.
- FIG. 1 shows that the transverse clearances J1-J2 provided between the tool 5 and its guide means 3 and 4, whatever their embodiments, are less than the clearance J formed between the keys 7 and the bottom of the notches 8 , so that, in no case, the tool can come into contact with the keys in its transverse movements.
- the tool When the tool is engaged deep in the ground and a resistant torque is applied on the whole of the front part of the device, the tool is set in rotation by its large active facets coming into contact with the facets opposite guide means 3.
- the clearance J is also determined so that the keys 7 cannot not come into contact with the tool in its working conditions.
- FIGS. 5 to 10 differ from the previous ones by the fact that the guide means 3 is not constituted by a socket but by at least two pairs of opposite plates 20, reported in the front guide 2. These plates can be distributed along the four sides of a square or a rectangle and can have planar active faces as shown in 21 in FIGS. 5 and 6, concave active faces as shown in 22 in FIGS. 7 and 8, or convex as shown in 23 in Figures 9 and 10. Their dorsal face can be flat or convex depending on the shape of the face against which they are supported.
- the plates delimit a guide zone, the guiding curve of which includes points of inflection delimiting edges 10 and plane or curvilinear facets.
- the cross section of the tool 5 is complementary to that of the guide zone, as already described in the previous embodiments.
