Definitions

  • the present invention relates to a marking machine.
  • It relates more particularly to a marking machine portable, i.e. capable of being moved to a piece to be marked remaining fixed.
  • a portable marking machine comprises a body, from which extends a marking stylus, terminated by a point, suitable for marking the piece, for example by striking or inkjet.
  • the body rests on three or four feet resting on the workpiece, appropriate places.
  • the machine is furthermore provided with holding means, such as a handle, allowing a operator to give constant positioning to the machine during the actual marking.
  • this type of marking machine has certain disadvantages.
  • Their size is relatively large due to made of the arrangement of the support legs according to a triangle or a quadrilateral.
  • the invention proposes to realize a portable marking machine which, while ensuring a marking of satisfactory quality, i.e. little bulky and can be adapted to a large number of surfaces, in particular to cylindrical surfaces of radius any curvature.
  • a marking machine comprising a body, a stylus terminated by a point of marking and body support means, intended to rest on a surface to be marked, characterized in that the means of support include two feet, one straight connecting the two feet, and a main axis of the stylus forming a main plane of the machine, said main plane being perpendicular to said surface to be marked in a set position, and what is provided for means of detecting an offset angularity of said main plane with respect to the position of setpoint, to allow a user, by toggling said machine, to bring the main plane back into the position setpoint.
  • FIG. 1 represents a portable marking machine, designated as a whole by the reference 2. It comprises a body 4 generally parallelepiped, from which extends a handle 6 allowing the machine to be held in place by a user.
  • Two legs 8, 8 'of elongated shape are fixed on two opposite ends of the body. They have main axes parallel, of which only one A is shown.
  • This stylus has a main axis A 'parallel to the axes A of the legs 8, 8'.
  • the tip 12 is arranged substantially on the straight line B, perpendicular to axes A and A ', connecting the ends of the legs 8, 8 'opposite the body 4.
  • the marking tip 12 is supplied in a known manner, for example by pneumatic means or electro-magnetic.
  • one 8 of the feet has a longitudinal groove 14 extending on all its main dimension and on part of its lateral dimensions.
  • the lower end of this groove 14, opposite the body 4 receives a rectangular block 16 articulated on the main part 18 of the foot 8, around an axis 17 parallel to the right B.
  • the line B defines, with the axis A ′ of the stylus, a plane P, said main plan of the machine 2.
  • This block 16 is provided, opposite the body 4, with two nipples 20 intended to come into contact with a part to to mark. Such contact must be stable, i.e. it does not allow any degree of freedom in rotation or translation of the block in relation to the surface of the part to be marked.
  • the pivoting of the block 16 around its axis 17 is limited by two lateral stops 22 mounted on the main part 18 of the foot 8.
  • Block 16 delimits, at its end opposite the nipples 20, a notch 24 in which is received the end of a needle 26 extending generally along the main axis of the foot 8.
  • This needle 26 is articulated on the block 16 around an axis 28, parallel to the axis 17. It is also possible to provide the needle 26 is free to pivot around one end protruding from the main part 18, like the beam of a balance.
  • the end 30 of the needle 26, opposite the block 16, extends in the vicinity of a mark 32 carried by the part main 18 of foot 8.
  • This mark is for example a line in hollow and / or colored.
  • a mirror 34, extending from the top of the main part 18, allows a user to view the area located near this marker 32, looking at in a direction generally perpendicular to the axis main A of foot 8. This is advantageous, especially in the case where machine 2 is used for marking vertical surfaces.
  • the other leg 8 ' is provided, at its end opposite to the body 4, of a terminal stud 35, similar to studs 20, which ensures a pivoting, non-sliding contact, of this foot 8 'on a area.
  • the main axis A of the foot 8 is perpendicular to a straight line C passing through the end free of nipples 20.
  • This position is called position of foot instruction.
  • a ball 36 is pushed, under the action of a spring 38, in a spherical recess 40 formed on the surface of the block, opposite the nipple 20.
  • This ball 36 and this spring 38 constitute means of recalling the part main 18 of foot 8 in this set position.
  • the mark 32 and the end 30 of the needle 26 are then aligned, to have that the straight line passing through this mark and this end is perpendicular to line C.
  • the pivoting block 16 associated with the needle 26 and the reference 32, allows to visually detect any offset of the axis principal A 'of stylus 10 with respect to the perpendicular axis at the tangent, at the point 12, at the surface at to mark.
  • the axis of the stylus 10 is inclined at an angle ⁇ relative to the line perpendicular to the tangent. This would therefore induce a poor marking quality, if the latter was used artwork.
  • Such pivoting induces a corresponding tilting of the needle 26 around its axis 28, so that the end 30 is no longer aligned with the reference 32.
  • This offset can be viewed by an operator looking along the main axis from the foot or transversely to the main axis A, through of mirror 34.
  • the operator pivot the main part 18 of the foot 8 relative to the block 16, so as to re-align the end 30 relative to at reference 32.
  • This alignment then allows the operator to know that the marking machine is again in the set position, illustrated in Figure 2, guaranteeing a good workmanship. The operator then proceeds to proper marking, holding the machine by means of the handle 6.
  • Figures 4 and 5 illustrate the great adaptability of the marking machine 2, as described above.
  • the machine 2 is suitable for marking a cylindrical surface S 'with a small radius of curvature (Figure 4) as well as a surface S '' whose radius of curvature is significantly more important (Figure 5).
  • Figures 6 and 7 show a foot 108 fitted to a marking machine according to a second embodiment of the invention.
  • This foot 108 is provided with a pivoting block 116, similar to that 16 of Figure 1, surmounted by a cap 120.
  • the latter which extends in the direction of the body 104 of the machine, has an end 122, the dimensions of which side are reduced.
  • the part thinned 122 is interposed between a lamp 124 and a cell photoelectric 126, both housed in the main 118 of the foot.
  • FIGS 8 and 9 show a foot 208 equipping a portable marking machine according to a third mode of realization of the invention.
  • foot 208 is provided with a single nipple end 220.
  • two rods 222, 222 ' are housed, being free to move around translation, in channels 224 formed in the part main 218 of the foot.
  • These channels which extend along the axis principal A of this foot, are opening at their two ends, namely that they communicate, upwards in these figures with a housing 226 formed in the main part 218.
  • the two rods 222, 222 ′ are pivotally mounted on a triangular part 228 received in the housing 226.
  • the articulation of the rod 222 on the part 228 is slidably mounted, at the within an oblong groove 229 extend transversely by relative to the axis of the foot 208.
  • a return spring 230 fixed to the lower base of the triangular piece 228, tends to bring this in the direction of the stud 220, in a position such that the straight line connecting the free ends of the rods 222, 222 ' either perpendicular to the main axis A of foot 208. In this setpoint position of the foot 208, the free ends rods 222, 222 ′ extend beyond the stud 220.
  • a thinned end 232 of the triangular head 228 is interposed between a lamp not shown and a cell 236, analogous respectively to those 124 and 126 described above.
  • the operation of the marking machine equipped with the foot 208 is explained below, with reference to FIG. 9.
  • the marking tip is not perpendicular to the surface S, as is the case in the arrangement of the figure 9, the same applies to the axis A of the foot 208.
  • the latter rests then on the surface only by means of the nipple 220 and of a single rod 222, while the other rod 222 'extends to distance from this surface.
  • This induces a pivoting of the triangular piece 228, so that the thinned end 232 is no longer interposed between the lamp and the cell 236.
  • this activates an alarm.
  • the user as well the lawyer is then able to bring the foot 208 back into its set position, bringing the rod back into contact 222 'with the surface S to be marked.
  • the pivoting part 228 may not have thinned end 232, but cooperate with a needle, similar to that 26 described with reference to Figures 2 and 3. In the set position, such a needle is aligned with a reference, similar to that 32 of these Figures 2 and 3.
  • a needle is aligned with a reference, similar to that 32 of these Figures 2 and 3.
  • the two feet of the machine are equipped with means for detecting an offset of their axes, as described above. This saves the user any superfluous displacement, insofar as it can check the correct positioning of the foot of which it is most close.
  • the invention makes it possible to achieve the objectives previously mentioned.
  • the detection means comprise a element, such as the needle 26, pivoting in synchronism either with the member 16, or with the part 228, the operator is at even to estimate, with satisfactory precision, the inclination possible foot relative to its setpoint axis. In the case where this inclination has a value sufficiently weak, the operator can then initiate the operation of marking proper, without additional tilting of the whole marking machine.
