Definitions

  • the present invention relates to a device for mounting a positioning detector of a pneumatic or hydraulic cylinder piston on the body of this last.
  • a position detector such as that a magnetic proximity sensor, on the body of a pneumatic or hydraulic cylinder to detect the position of the piston of this jack.
  • a support rail with a groove is mounted axially on the cylinder body, between its two ends.
  • the groove is directly integrated on the body of the cylinder.
  • the detector is then placed in this groove and is held in position using fasteners appropriate (screw type, etc.).
  • EP-A-0 894 983, WO 91/19907, DE 196 53 222 constitute examples illustrating these known techniques.
  • Such configurations have the advantage of being able adjust the position of the detector along the groove, in the axial direction of the cylinder body, which allows choose the position of the piston you want detect.
  • the detector when it is a rail mounted on the body of the cylinder, the detector is conventionally inserted in the rail support by one end of the latter, and it's therefore necessary to dismantle it before being able to remove said detector.
  • detectors are generally such that when mounted in their support groove they protrude from this support so that these detectors have a surface significant exposed to possible shocks which could disturb them, or even damage them.
  • the present invention aims to overcome such drawbacks by proposing a device for mounting a position of a pneumatic or hydraulic cylinder piston on the body of said cylinder, which allows very easy disassembly easy of the detector, without having to disassemble the cylinder in whole, and whose particular form allows audit detector not to be protruding from its support.
  • Figure 1 represents a first embodiment of the device according to the invention, sees that this consists of a detector 1 mounted on the body 2 of a pneumatic or hydraulic cylinder.
  • a piston (not shown) is positioned inside the body 2 said cylinder so as to move therein in a movement of alternative translation.
  • an annular magnet in front to be detected by detector 1 is mounted on the surface external of the piston.
  • this is in the form of a magnetic proximity which outputs a signal when a magnet (the object detected) approaches it.
  • the detected object and the detector are not limited a magnet and a proximity sensor respectively magnetic.
  • the detected object can be realized metal and the detector can be a high detector frequency which detects an induced signal and transforms it into output signal.
  • the device for mounting the detector 1 comprises, in known manner, a rail 3 by which said detector is positioned on the cylinder body 2 pneumatic or hydraulic.
  • this rail 3 is, either attached to the body 2 of the jack using suitable fasteners (see Figure 1), either is an integral part of the outer surface of said body cylinder (see Figure 2).
  • the rail 3 has a groove 4 whose cross section in dovetail shape is suitable for receiving detector 1 (cf. figure 5).
  • the detector 1 is then mounted on top of said rail, in the groove 4 arranged thereon, which avoids to have to dismantle the latter during the installation or removal of said detector.
  • this rotation of the screw 6 or the like has effect of positioning the pivot 5 so that it makes protrusion from the side walls of the detector 1.
  • the pivot is then inserted into the bottom of the groove 4 in dovetail shape, rises slightly under the effect of the rotation of said screw, and thus blocks said detector in position, without generating any compression force on it (see Figure 5).
  • the detector 1 can slide in the groove 4 to choose the position of the piston you want detect. To do this, rotate the screw 6 or analog then allows to reposition the pivot 5 in the light 7 to allow the movement of the detector the along the body 2 of the jack.
  • the detector 1 has an upper surface such that, when said detector is mounted in groove 4, this surface is flush with the rail 3.
  • the detector does not does not protrude from the groove 4 in the form of dovetail which protects it from possible shocks and improper handling that could disrupt it, or even damage it.
  • the device may include a plate 8 capable of being positioned in groove 4 so as to keep in position a power cable 9 of the detector 1 in the bottom of said groove.
  • This plate 8 associated with the shape particular of detector 1, thus avoids any unintentional disturbance of the detector position, the whole being perfectly integrated inside the groove 4.
  • the present invention offers multiple benefits; in particular it brings a device for mounting a detector which is simple to produce, easy to use that allows the installation and removing the detector without having to dismantle the cylinder or any mechanical device incorporating the latter.
