Definitions

  • the present invention relates to a rivet processing device for broken mandrel rivets with monitoring of the setting process.
  • this object is achieved in that a pressure measurement sensor is arranged between the mouthpiece sleeve and the housing of the rivet processing device. This makes subsequent assembly considerably easier, since the mouthpiece sleeve must be replaceable anyway, since on the one hand it wears out very heavily and on the other hand the mouthpiece sleeves when changing to a different rivet type or a different rivet size usually have to be replaced anyway.
  • the pressure measurement sensor is particularly preferred to design the pressure measurement sensor as a length measurement plug or a measurement washer.
  • the invention further teaches that a considerable improvement in the accuracy of the monitoring of the riveting process is possible if, in addition to the pressure measurement between the mouthpiece sleeve and the housing, a displacement measuring device is arranged on a piston rod of the rivet processing device. A pressure-path diagram can then be generated for each riveting process, which allows even more precise conclusions to be drawn about the quality of the riveting process.
  • a displacement measuring device preferably comprises a conical section on the piston rod and a distance sensor which is firmly connected to the housing.
  • This distance sensor is preferably designed as an inductive analog displacement sensor.
  • Figure 1 is a sectional view of a rivet processing device according to the invention from the side.
  • Figure 1 shows a conventional rivet processing device for broken mandrel rivets in a sectional view seen from the side, which is equipped with a device according to the invention for monitoring the setting process.
  • a strain gauge plug 2 is arranged in an adapter 1 between the mouthpiece sleeve 12 and the housing 14.
  • the strain gage 2 is provided with a protective cover 3.
  • the pressure force between the housing 14 and the mouthpiece 12 can be continuously measured and monitored by means of the strain gauge plug 2.
  • an inductive analog displacement sensor 5 is provided according to the invention. With this, the course of the setting process is measured simultaneously.
  • the inductive analog displacement sensor 5 is arranged in an intermediate piece 4, which is located between the housing 14 and the rivet mandrel collecting container 16. Retrofitting is also relatively easy here, since the rivet mandrel collecting container 16 and the housing 14 are only screwed together and the adapter can therefore be placed in between.
  • the setting path is now measured by arranging a conical section 7 on the extended piston rod 6.
  • the conical section 7 is laterally moved past the analog displacement sensor 5, the distance between the conical section and the analog displacement sensor changes proportionally, as a result of which a signal is generated which is exactly proportional to the setting path.
  • the corresponding data is collected via a cable 8 and passed to the device compressed air connection via the hand protection, where the data can be forwarded to a corresponding recording or processing device separately or in connection with the compressed air line.
  • any conventional rivet processing device for broken mandrel rivets can be retrofitted with a monitoring device according to the invention.
  • the force - displacement sensor system for process-controlled processing of broken mandrel rivets is particularly advantageous here.
  • a length measuring plug strain sensor
  • This version can be used advantageously in the immediate vicinity of the riveting equipment (mouthpiece sleeve) and in the direction of the reaction force. This leads to a small size.
  • the reaction force is measured in an adapter 1, which is located between the device housing 14 and the mouthpiece sleeve 12.
  • the adapter 1 is screwed. Through the application of force during When the rivet is placed in the mouthpiece sleeve 12, this force is transmitted to the adapter 1 and provides measurable values for the change in the modulus of elasticity of the material of the rivet.
  • the adapter 1 Since the adapter 1 is firmly connected to the housing 14 of the device, it is not touched when the riveting equipment is changed, for example because of wear or to change to a different rivet size. This avoids additional calibrations.
  • measuring washers can also be used according to the invention. These are then also arranged between the adapter 1 and the device housing 14. Alternatively, an expansion transmitter could be screwed onto the adapter or the device housing.
  • the compensation for the increased distance between the mouthpiece sleeve 12 and the housing 14 by the present invention takes place by an extension of the pulling part, which is screwed between the piston rod 6 and the riveting equipment (clamping jaw cartridge).
  • a parallel displacement measurement is carried out.
  • this can take place directly on the piston rod 6 of the device.
  • the rear piston rod 6 is extended and protrudes from the space of the hydraulic cylinder.
  • a conical section (measuring bush) is mounted on this piston rod. This can be adjusted in the axial direction on the piston rod 6 and thus offers fine setting options for the distance measurement.
  • an inductive analog position sensor is permanently attached in an adapter. This inductive analog displacement sensor can be designed to be adjustable in the adapter radially to the conical section of the piston rod.
  • the adapter 4 according to the invention is placed on the rear part of the housing 14 instead of the rivet mandrel collecting container 16. screwed.
  • the analog position encoder thus has an unchangeable position. While a rivet is being set, the piston rod is moved backwards (device stroke), as a result of which the conical section 7 of the piston rod 6 moves past the measuring surface of the analog displacement sensor 5.
  • the conicity of the conical section 7 measures the distance between the surface of the conical section 7 and the analog displacement sensor 5, which changes during the stroke in accordance with the horizontal movement of the piston rod 6.
  • This embodiment preferably results in a particularly small installation space, the rivet mandrel collecting container is then screwed onto the other end of the adapter 4.
  • an analog displacement sensor instead of an analog displacement sensor, other displacement measurement methods can of course also be used.
  • a magnet can be attached to the piston rod instead.
  • an inductive displacement sensor is then used.
  • the corresponding cable connections run from the adapter 4 for the inductive analog displacement sensor 5 along the outside of the housing 14 to the adapter 1 of the strain gauge plug 3 and from there through the hand guard 8 to the preumatic connection located below.
  • the present invention allows a very simple and inexpensive retrofit of commercially available mandrel break rivet processing devices with a device for monitoring the riveting process.
