Definitions

  • This invention refers to a device for the precision cleaning and/or deburring of orifices in machined parts, designed for fitting in the cleaning chambers of the cleaning and/or deburring stations of cleaning machines for machined parts.
  • Machined parts for kinematic and dynamic systems are fitted with orifices and ducts for channelling and receiving lubricating or cooling fluids.
  • Machined parts likewise feature a number of blind, threaded orifices designed to take threaded fasteners.
  • the aim of this invention is to solve the drawbacks mentioned above, providing a device for the precision cleaning and/or deburring of orifices in machined parts, one giving suitable movement and positioning relative to each other of the cleaning or abrasive liquid jet and the part to be cleaned, in order to obtain better results in the cleaning process.
  • the device of this invention is characterized in that it has:
  • said means of supporting and spinning the part to be cleaned comprises two points for holding the part, which determine the axis around which the part can be spun during the cleaning and/or deburring operation, at least one of the holding points being fitted with rotating grippers that grip the part and are driven by one numerical-control motor, which governs the spinning of the part enabling it to take up a number of pre-programmed positions around its axis of rotation.
  • the above-mentioned carriage supporting the cleaning equipment comprises a frame supporting a driving member, such as a hydraulic or pneumatic cylinder; a vertical arm, carrying the lances that hold the nozzles, that can travel vertically when the driving member is operated; guide bearings for said vertical arm; and a nut, operating in conjunction with a horizontal leadscrew, fitted on the frame of the cleaning machine and driven by a second numerical-control motor, the latter also being fitted on the frame of the cleaning machine.
  • a driving member such as a hydraulic or pneumatic cylinder
  • a vertical arm carrying the lances that hold the nozzles, that can travel vertically when the driving member is operated
  • guide bearings for said vertical arm guide bearings for said vertical arm
  • a nut operating in conjunction with a horizontal leadscrew, fitted on the frame of the cleaning machine and driven by a second numerical-control motor, the latter also being fitted on the frame of the cleaning machine.
  • the above-mentioned means of closing the opening in the upper face of the cleaning chamber consists of horizontal plates arranged to form a labyrinth.
  • Fig. 1 shows a part 1 to be cleaned and/or deburred - in this case an engine crankshaft - in which the orifices 2 to be cleaned are shown.
  • the part 1 can be moved by a feeder unit 3, e.g. of the stepped-pitch type, fitted, by way of example, with a conveying bar that can move upwards, forwards, downwards and backwards.
  • Fig. 1 shows the part 1 in its position as removed from the feeder unit 3 and set in the means for supporting and spinning it. These means are fitted, to one side of the part 1, with a set of grippers 4 that close on the part 1 in order to move it along, and a centring device 5 which penetrates inside a suitable zone of the part 1.
  • the set of grippers 4 and the centring device 5 are driven by an actuating cylinder 6, preferably hydraulic though it could also be pneumatic or electric, arranged in such a way that it can make the centring device 6 move onwards - in the directions shown by the arrows A - and the grippers 5 close on the part 1 - with the movements shown by the arrows D - gripping it, a function that can be arranged, for example, by a mechanical device involving a lever or rack-and-pinion system.
  • the set of grippers 4, the centring device 5 and the cylinder 6 are joined to a support 7, and spin together around at least one bearing 8, the base of which is joined to the cleaning machine.
  • the support 7 is joined to a crown wheel 9 driven by a numerical-control motor 10 through a pinion 11 and a transmission belt 12.
  • the means for supporting and spinning the part are equipped with another supporting device whose function is to support the part at its other end.
  • a tailstock 13 driven in its movement by the part of the means of supporting and spinning the parts fitted on the first side described, and spinning freely on a bearing 14 held by a support 15 attached to the cleaning machine.
  • Fig. 2 shows in diagrammatic form the cleaning equipment and the means of closing that are to be used in conjunction with the mechanisms shown in Fig. 1, as explained hereabove.
  • the cleaning equipment is provided with a nozzle 17, arranged to create the flow of cleaning material, plus at least one supporting lance 18, joined to the nozzle 17 and fitted on a support 19 joined to an arm 20.
  • This arm 20 can be raised or lowered, driven by a cylinder 21, in the directions shown by the arrows B, in order to move the lances 18 away from the part 1 to be cleaned when that part is required to move on conveyed by the stepped-pitch feed device.
  • the arm 20 can slide along guide bearings 23 fitted on a frame 22 which can move transversely, as shown by the arrows C, with respect to the feed direction of the leadscrew, in a direction that is parallel to the axis of rotation of the part 1 and perpendicular to the direction of the sliding movement of the arm 20.
  • This transverse movement is preferably transmitted through a leadscrew 27 driven by a second numerical-control motor 24.
  • a rack-and-pinion system could be used for that transmission instead of the leadscrew 27.
  • Most of the unit formed by parts 21, 22, 23, 24, 26 and 27 is preferably located outside the cleaning chamber of the cleaning machine and is isolated from the outside by a means of closing, comprising a group of closing plates 25 forming a labyrinth.
  • the device works as follows: firstly, the part 1 is brought by the feed device 3, to which it is attached by known means, to the right position near the means of supporting and spinning; next, the latter clamp the part at both ends; then the stepped-pitch feed device 3 releases and moves away from the part 1, which is left ready to spin around through the agency of parts 6 to 11; afterwards, part 1 is spun to the required angle; then the nozzles 17 of the cleaning equipment are brought, through the action of the cylinder 21 and the motor 24 to the required position with respect to the part 1; at this stage the cleaning and/or deburring operation can be commenced by the ejection of a jet of cleaning material through the nozzle 17 against the part 1.
