Definitions

  • the present invention relates to a device for rapidly mounting a mechanical assembly on a support. It relates notably to the mounting of a tool on a support, for example a vibrating support, notably for a testing station.
  • the subject of the invention is a device for mounting a mechanical assembly on a support comprising at least one mounting module having a male part mechanically fixed to the assembly and a female part mechanically fixed to the support, the male part fitting into the female part, the female part having a thrust system locking the male part against a wall of the female part once the male part has been fitted thereinto.
  • the male part may have a projecting portion penetrating into the modified side wall of the female part, the projecting portion being locked into the modified side wall under the effect of the thrust of the system.
  • the female part has, for example, a side wall with a conical internal form, the male part then having a conical portion which locks into the conical internal wall under the effect of the thrust of the system.
  • the thrust system may be a cylinder, for example a double-acting cylinder.
  • the device has, for example, a circuit for pressurizing the cylinder of a mounting module.
  • the support is, for example, a vibrating table.
  • the mechanical assembly is, for example, a tool.
  • FIG. 1 shows a simplified overall view of a tool mounted on a support by a device according to the invention
  • FIG. 2 shows an embodiment of a mounting module, a constituent part of a device according to the invention.
  • FIG. 1 shows, by way of an overall view, a tool 1 mounted on a support 2 by a device 3 , 4 according to the invention.
  • the device according to the invention has a set of mounting modules 3 connected, for example, to a supply circuit 4 , for example under pneumatic or hydraulic pressure.
  • FIG. 2 shows a schematic view of an exemplary embodiment of a mounting module 3 .
  • the mounting module has a female part 21 and a male part 22 .
  • the female part 21 is mounted on the support 2 .
  • This part 21 is, for example, mounted on the support 2 by way of a screw 23 .
  • the male part is mounted on the tool itself, for example by means of a mounting screw 24 .
  • the male part 22 and the female part 21 may be fitted together without play.
  • the female part 21 has, for example, a base 210 in contact with the support 2 , having, for example, at least one hole for the mounting screw 23 to pass through, side walls 211 , 212 and optionally an upper wall 213 , thus forming a box.
  • An opening 214 is provided for the male part 22 to pass through.
  • the male part has a side wall 212 having a conical internal form. This conical internal form is designed to receive a portion 221 of the male part 22 having a conical projecting form.
  • the female part 21 has, moreover, a cylinder 25 , 26 mounted, for example, on the side wall 211 opposite the side wall 212 having a conical internal form.
  • the piston 26 of the cylinder pushes the male part 22 such that its conical portion bears against the conical internal wall 212 , bringing about the mounting of the male part in the female part and therefore the mounting of the tool 1 on the support 2 .
  • This mounting is brought about by the pressurization of the cylinder 25 , 26 by the supply circuit 4 .
  • the cylinder may notably be pneumatic or hydraulic.
  • an adaptor 27 connects the cylinder to the supply circuit 4 .
  • a mounting device has as many mounting modules 3 as are required for the size of the tool. Once the male parts are fitted into the female parts, mounting is brought about by the activation of the cylinders 25 , 26 provided within the female parts 21 . If the cylinders are of the pneumatic type, they can be supplied by a compressed air circuit 4 which is generally available in factories.
  • the support 2 may be a vibrating table, depending on the equipment tested, for example.
  • the invention allows tools to be mounted while dispensing with the conventional screw mounting which requires a considerable intervention time under lengthy, tiresome and difficult accessibility conditions, since it may notably be necessary to remove some equipment from its support, to bend down, or even to get into the vibrating machine in order to unscrew numerous screws that are difficult to access between the uprights holding the equipment and the ventilation ducts.
  • the invention allows any type of tool to be mounted, without play and in a few seconds, in an environment that is very restricting in terms of vibration and temperature. It can be attached to existing tools by the addition of one or more male parts 22 having a complementary conical internal form 221 and attached for example permanently to the tool, in place of each of the former mounting screws.
  • the female part 21 includes, for example, the cylinder 25 , 26 supplied, for example, with compressed air from the factory network if it is pneumatic.
  • the female part 21 is thermally insulated in order to reduce the impact of thermal shocks on the reliability and efficiency of the cylinder, the pressing capacity of which is chosen depending on the maximum density of the equipment, on the measurements between the former mounting screws, on the level of vibration to be transmitted between the table and the tool 1 , and on the ambient temperature extremes.
  • the conical form and complementary conical form 212 , 221 are chosen to allow multidirectional locking and thus to bear vibrations and forces in all directions without play and without absorbing the vibrations and forces to be transmitted.
  • the preload required at the cylinders takes account of the maximum forces encountered in order that the form and the complementary form 212 , 221 never come apart during tests.
  • the angle of the cone is likewise chosen in order to prevent jamming between the form and the complementary form during disassembly.
  • the cylinder is chosen for example to be double-acting in order for the cone to be easily removed from the complementary form during disassembly of the tool/equipment assembly, without the worker intervening in the chamber.
  • the invention has variant embodiments, such as:
  • the invention has very many advantages. It allows the creation of a standard for rapid mounting (replacing a screw with a system), the use of pre-existing interfaces, rapid prepositioning techniques, rapid mounting, the use of factory compressed air, the transmission of vibrations without damping and without attachment play (very damaging in a vibrating environment). Further advantages of the invention are the possibility of changing the tool in less than a minute, resistance to severe environmental restrictions (in terms of vibration and climate), ultrafast reconfiguration of the production line, and zero or very low servicing and maintenance costs.
  • the invention may, moreover, be adapted to any type of testing station requiring frequent changes of mechanical interface, such as vibrating pots for example.
