Definitions

  • the invention relates to a pneumatic end position interrogation device for jig headpieces with one clamping arm actuating mechanism actuated by a linear actuator, the linear actuator being a sensor for two arranged one behind the other in the encoder setting direction Has pneumatic switch that is adjustable relative to each other are.
  • Such end position interrogation devices are in particular on clamping devices for fixing workpieces well known and in use so that it is relevant no special printed evidence requirement. It is in particular on such clamping devices of interest, the end positions, i.e. on the one hand the Clamping position of the actual, from the linearly movable Actuator actuated arm and on the other hand, the Display opening position via control signal and for the control of the tensioning device in a suitable manner implement, the triggering of the control signals with a arranged on the linearly movable actuator takes place in the travel of the two pneumatic switches are arranged one behind the other. At least one of these Switch, namely for the open position indicator, is adjustable over a relatively large range fixed to the carrier.
  • an end position interrogation device of The invention is the object of the invention based on such a pneumatic end position interrogation device to improve in that this to is spatially as compact as possible, on the other, separate, for the two pneumatic switches pipelines brought in from the outside are unnecessary and also relatively small opening angle positions with the pneumatic switch in question can be detected.
  • both pneumatic switches on one the Carrier strip containing pneumatic channels arranged are who the open position switch and fixable with its base is assigned that in the base the opening position switch towards the carrier bar open overflow channels parallel to the permanent pressure channel and on the other hand to the control pressure channel for the Open position indicator are arranged, wherein Permanent and control pressure channels distanced from each other have overflow bores leading the overflow channels and that between the contact surface of the base and the Support surface of the support bar one of both surfaces pressable surface seal with the overflow channels corresponding Slots is arranged.
  • This training according to the invention eliminates within the installation of all hose line guides to the two switches as these are drilled in the Carrier strip are replaced.
  • a pneumatic switch covering housing can be dispensed with, since the Carrier strip the located or arranged thereon Pneumatic switch covers itself, which is explained in more detail becomes.
  • the pneumatic switch for the Open position indicator because of hose lines not more handicapped, pretty close to the other pneumatic switch be put up, i.e. they are too small opening angle positions for the tension arm (between 30 ° and 60 °) detectable.
  • an advantageous further training consists in that the pneumatic switch at one end of its Base arranged and parallel in its contact surface and another overflow channel at the same distance is arranged. Because of what is explained in more detail below the pneumatic switch for the open position indicator just in the opposite direction the carrier strip are attached, the additional Overflow channel takes over the corresponding function.
  • the support bar in the area next to the pneumatic switch for the Tension position indicator is provided with a recess, in their longitudinal side flanks parallel to each other longitudinal grooves are arranged and that in one in the recess engaging base part slightly to the longitudinal grooves offset, a transverse recess with therein Rollers is arranged between the middle and perpendicular to the recess at the effective end frustoconical clamping element is directed.
  • the interrogator sits at one For example, fork-shaped head piece between its legs or in an appropriately sized slot, if it is a closed, i.e. bowl-shaped head piece acts.
  • the outer leading to the interrogator three pneumatic lines are on three connections of the Carrier strip connected, so do not hinder the adjustability the open position switch.
  • the starting point was a pneumatic one End position interrogation device for clamping device head pieces K with one of a linear actuator LS actuatable clamping arm actuating mechanism M, the linear actuator LS one encoder G for two in the encoder setting direction Pneumatic switches 1, 2 arranged one behind the other has, of which the open position switch 2 adjustable is.
  • the clamping device or its head piece K so it is in the embodiment a closed head piece K, on which the not shown Tension arm on the laterally protruding square shaft journal WZ sits, whose end positions (clamping position / opening positions) are to be queried.
  • the permanent and control pressure channels 4, 3 point apart from each other Overflow channels 7, 8 leading overflow bores 9, 10 on, and further between the contact surface 11 of the Base 2 'and the bearing surface 12 of the support bar 6 a surface seal 13 which can be pressed from both surfaces is arranged, the corresponding to the overflow channels 7, 8 Slots 14, 15 is provided.
  • the pneumatic switch is 2 arranged on the base 2 'at one end region, and in its contact surface 11 is parallel and at the same distance a further overflow channel 7 'is arranged.
  • a further overflow channel 7 ' is arranged.
  • the support bar 6 in the area next to the Pneumatic switch 1 for the clamping position indicator with a Provide recess 16 in the longitudinal side flanks 16 ', longitudinal grooves 17 are arranged parallel to one another, being in a base part engaging in the recess 16 2 '', slightly offset from the longitudinal grooves 17, one transverse recess 18 with located therein Rollers 19 is arranged between the center and perpendicular to the recess at its end a truncated cone Clamping element 20 is directed.
  • a fastening extension 22 is arranged at the end of the carrier strip 6, the fastening extension 22 advantageously having axially adjustable fasteners such as grub screws with tip 23, ball spring element 24 or spring-loaded Locking pin 25 is provided (see Fig. 7A-C).
  • FIGS. 6A, B differs 3, 4 only to the extent that here and at basically the same design of the pneumatic switch 1 like the pneumatic switch 2 also the pneumatic switch 1 for the detection of the clamping end position the support bar 6 is arranged adjustable. A such adjustability is of interest insofar as thus dead center, dead center and bottom dead center positions of the clamping arm can be set and queried.
  • the adjustability of both pneumatic switches 1, 2 is the carrier bar 6 'in contrast to that 3, 4, extends straight.
  • the permanent pressure line 4 operates both pneumatic switches 1, 2.
  • FIG. 1 shows the clamping device equipped with the interrogation device in a position in which the clamping arm reaches its closed or clamping position and the encoder 1 has switched the print head D1 of the pneumatic switch 1.
  • the pneumatic switch 1 acting as a valve (also applies to the pneumatic switch 2) opens the connection to the control pressure channel 5, which passes on the pressure pulse.
  • the pneumatic switch 2 is on the carrier strip, for example. positioned approximately in the middle so that the tension arm when opening the jig, i.e. from drive A of the linear actuator LS causes, for example, 90 ° from the clamping position is pivoted back.
  • this opening position contacts the one located on the linear actuator LS Encoder G the print head D2 of the pneumatic switch 2, the so that the connection to the permanent pressure channel 4 via Overflow bores 9, overflow channel 8, connection 5 ′′, Overflow channel 7, overflow bore 10 to the control pressure channel 3 manufactures.
  • the slits shown Overflow channels 7, 8 only in the base 2 '' of the pneumatic switch 2 are located and the length of the necessary Adjustment range of the pneumatic switch 2 accordingly are dimensioned, i.e. in each adjustment position Detect holes 9, 10 in the support bar 6.
  • the pneumatic switch 2 is turned 180 ° to be arranged on the carrier bar 6, whereby the print head D2, with basically the same position as shown, in the position indicated by dashed lines in Fig. 3 arrives, which is a much larger open position or the pivoting position of the tension arm corresponds. In spite of This can adjust a large opening angle the total length of the support bar 6 is significantly reduced will.
  • the pneumatic switch 1 with its print head D1 must also not as high as shown, in the head 6 '' of the support bar 6 can be arranged, but can be much deeper sit (see for example Fig. 6A, B), which means that even very small opening angles below 60 ° to 30 ° and can be queried.
  • the pneumatic switch 2 Since the interrogation device is tight during operation, on the other hand, at least the pneumatic switch 2 is adjustable must be, as explained above, this requirement corresponded by an education according to FIG. 5, which for a quick release of the base 2 '' for adjustment allowed, but also at the same time the required pressing of the correspondingly slotted Surface seal 13 allows. Will that be in the pneumatic switch 2 screwed in, at its end with a truncated cone provided clamping element 20 released, get the Rolling body (see also Fig. 3) sufficient lateral play and release the base 2 ''. When positioning is achieved of the pneumatic switch 2 is then the clamping element 20th simply tightened again, what to fix to the support bar 6 and for pressing on the surface seal 13 leads.
  • the carrier bar fulfills 6 also the cover function of a otherwise required cover - is the bracket the interrogator to make it easier and faster Removal and reusability, as also briefly explained, designed.
