Definitions

  • the invention relates to a mounting device for attaching small parts according to claim 1.
  • Such a device is known, for example, from DE 24 54 804 C3 and the corresponding US-A 4 048 461.
  • the contact metal blanks are introduced in a direction of approach of the electrodes approximately orthogonal insertion plane into a receptacle of the movable electrode and then with the movable electrode along the Sch sparoismosline approximated to the support member and clamped together with the support member between the two electrodes.
  • the contact metal blank to be processed in each case is in this known device of the recording of the movable electrode added when he begins the movement in the direction of the support member. He is not secured in the electrode.
  • the known device is therefore bound to arrange the movable electrode so that when approaching the movable electrode to the support member of the respective contact metal blank is held by gravity in the receptacle of the movable electrode.
  • the known device has also been further developed to the effect that the recording of the contact metal blank in the one electrode was assigned a suction nozzle, so that after receiving the respective contact metal blank in the recording of the electrode in question a backup of the contact metal blank could be ensured in this recording by negative pressure. It has been found that, although the whereabouts of the contact metal blank could be secured within the recording of the respective electrode by such a suction nozzle regardless of the position of the electrodes in space, but in the subsequent welding by the existence of the suction nozzle to the finished molded metal part contact an imprint originated, which the exact, desired Form of the contact metal part has falsified and was the cause of faulty behavior of the contact metal part during operation and for premature wear of the contact metal part in operation.
  • a device for attaching contact metal blanks to support parts by welding is known.
  • the contact metal blanks are cut from a wire or strip material, already at a location outside the respective welding gap.
  • the cut contact metal blanks are then advanced by advancing the leading end of the wire or ribbon forming the contact metal blanks in a guide until they enter the weld gap.
  • the guide guiding the singulated contact metal blanks can only extend to a point shortly before, but in any case outside, the welding gap, so that this guide can not interfere with the subsequent welding either mechanically or electrically.
  • the contact metal blanks rest unsecured on the respective electrode and therefore may be subject to local displacements when the electrodes approach.
  • the position of the electrodes in space and the direction of their approach movement is not arbitrary.
  • a device for welding balls to a pipe piece is known.
  • ferromagnetic balls are processed.
  • the balls are brought by introducing means in a welding preparation position opposite to one of the electrodes and are held in the region of this one electrode by magnetic holding means in welding preparation position. If the magnetic retaining means have become effective, the introduction means, which have previously brought the ball in the welding preparation position, can be withdrawn, wherein the respective ball then maintains its position relative to the electrode. Subsequently, the second electrode can then be aligned with the first electrode and approximated to the first electrode.
  • This known device requires a very complicated mechanism and is basically only usable when ferromagnetic welding metal blanks are processed.
  • the introduction means comprise at least one blank holder which is movable along the introduction plane into a blank dispensing position and which is designed to hold in its blank dispensing position the respective contact metal blank in its welding preparation position within the welding gap.
  • the control means are designed such that after introduction of the contact metal blank into the welding preparation position, a relative approaching movement of the welding electrodes along the welding movement line until joint clamping of the carrier part and the contact metal blank between the first and the second welding electrode, then the blank holder is removed from the blank dispensing position and then the welding current transition is initiated.
  • the gap which after the occurrence of clamping its height approximately equal to the height of the respective contact metal blank is preferably ensured that the blank holder in the direction of the welding movement line has an extension which is less than the height of the contact metal blank in this direction.
  • this requirement must be met only for those areas of the blank holder, which even enter the welding gap.
  • the blank holder must be formed so that it detects the contact metal blank in a space disc, which lies in the direction of the Sch spagolsline between a carrier surface facing the contact surface and one of the first welding electrode facing contact surface of the justifymetallrohlings.
  • the blank holder may be formed so that the contact metal blank is immovably held in its welding preparation position in the introduction level. This is to say, in other words, that the blank holder in the weld preparation position of the contact metal blank suppresses any unintentional movement of the contact metal blank parallel to the introduction plane.
  • the blank holder allows the contact metal blank in the welding preparation position compensating movements orthogonal to the introduction level. In that case, the contact metal blank can in fact approach itself when approaching the welding electrodes to the respective end position of the welding electrodes in which the clamping occurs.
  • the blank holder can in principle be designed as a clamping holder, for example in a pliers or fork shape or hairpin shape.
  • a clamping blank holder the secure positioning of the contact metal blank usually readily is guaranteed, it should not be ruled out in principle that the blank holder is carried out with suction means to ensure additional security of positioning.
  • These suction means can be carried out here easily with a suction nozzle. Namely, this suction nozzle can not give rise to an unintentional impression deformation of the contact metal blank, because the blank holder is no longer present at the welding location during the welding process, but has previously been withdrawn.
  • An embodiment of the blank holder with magnetic means should not be excluded in principle in the event that ferromagnetic contact metal blanks are processed.
  • the blank holder is preferably associated with blank holder guide and drive means which cause the blank holder to perform a reciprocating blank inserting and welding gap dis- placement movement in the insertion plane.
  • the blank insertion movement then brings the contact metal blanks into their weld preparation position.
  • the welding gap displacement movement the blank holder can be withdrawn without hindrance by now clamped between the contact carrier and electrode contact metal blank in a position in which the blank holder obstructs neither further electrode approach during the welding process still causes the risk of electrical short circuit or shunt.
  • the blank holder guide and drive means may be configured such that the blank holder performs substantially linear blank insertion and sealing gap dislocations in the region of the welding electrodes within the insertion plane, for example linear movements along a linear guide path indicative of the blank dispensing position. However, it does not depend on a strict linearity of these movements; It is conceivable, for example, that the blank holder moves along a curved path into the blank dispensing position and in turn moves back along a curved path from the blank dispensing position before the actual welding process begins.
  • the blank holder guide and drive means are adapted to each cause a transitional movement of the blank holder between a Sch Strukturspaltdistanz iststerrorism and a subsequent Rohlingseinbringungsterrorism, in the course of the blank holder passes into a blank receiving position, where it cooperates with Rigsingsbeschickungsstoffn.

  • the swivel arm is fixed on the carriage in a movement range of the carriage near the blank feed means and executes a reciprocating linear movement in the direction of the feed means or away from the feed means.
  • all essential movements of the contact metal blank are then moved into approximately one line of movement, which leads to a further increase in compactness.
  • the pivoting movement of the pivot arm on a carriage can be achieved in that the pivot arm is caused to pivot by means of a rack and pinion drive.
  • the pivot arm is then performs a common linear motion with the carriage, which serves the blank insertion and nip at one end of the carriage movement and, if desired, at the other end of the carriage movement to approach the blank holder can lead to the blank feed means and after loading of the blank holder for the withdrawal of the blank holder from the blank feed means.

  • a reciprocating pitch circle in particular semicircular movement
  • the device can then directly adjoin a neighboring subassembly of a higher-level machine without the possibility of movement collisions.
  • the design according to the invention of the introduction means is in principle not bound to a specific design of the blank feeding or blank feeding means to the blank holder.

  • another welding device 12 which welds contact metal blanks 14 onto the underside of the carrier parts 10-1 - 10 - 3.
  • the welding devices 12, 12 'and 12 are mounted as preassembled units on a tooling plate 136 of the assembly machine 128 and can be attached or detached as needed.
  • the contact metal strand 16 for forming the individual contact metal blanks 14 in the respective welding devices 12, 12' and 12" is supplied through the tool plate 136 from the back of the mounting machine 128 forth.
  • the pivot arms on the lateral boundary surfaces 49 and 49 'of the two adjacent welding device 12 and 12' on one side with the adjacent transfer devices are arranged so that the pivot arms after swing out in opposite directions, which is illustrated in Fig. 6 by arrows 138 and 139, and can not touch. Therefore, the welding devices 12 and 12 'can abut each other in the sense of optimum space utilization.
  • FIG. 7 there is shown an embodiment modified with respect to the feeder and the transfer device, the illustration being limited to the essential parts.
  • analogous parts to parts of Figs. 1 - 4 by analogous reference numerals, each augmented by the number a, respectively.
  • a total of four pivot arms 58a-1 - 58a-4 are mounted on the pivot hub 52a; the pivot hub 52a is in this embodiment, in each case advanced by 90 °, always in the same direction.
  • the clamp receiver 62a-2 of the swing arm 58a-2 of the feeder 140a just receives a contact metal blank 14a.
  • the hub 52a moves by means of a carriage corresponding to the transfer carriage 44 of Fig. 3 in the direction of the linear guide track 142a, so that the clamp receiver 62a-4 of Swing arm 58a-4 enters the blank dispensing position A in the region of the welding gap 30a.
  • the contact metal blank 14a is clamped by the clamp receiver 62a-4 by welding electrodes, not shown.
  • the pivot hub 52a is moved back toward the linear guideway 142a. During this return movement, the pivot hub 52a rotates by 90 ° clockwise, so that after completion of the backward movement and this rotational movement, the clamping receptacle 62a-1 of the pivot arm 58a-1 enters the blank receiving position E and receives there a blank 14a.
  • the rotation of the pivot hub 52a in the course of each backward movement of the pivot hub 52a to the right is accomplished by a pawl mechanism.
  • a contact metal blank 14a is pushed by a push-in pin 144a into the respective clamp receiver.
  • the contact metal blanks 14a are fed from a blank container 146a via a blank channel 148a.
  • the promotion in the blank channel 148a can be done pneumatically, for example.
  • the blanks 14a come in this way to rest against the tip of the plunger 144a and can be pushed by the latter into the respective clamping receptacle 62a-1 - 62a-4.
  • monitoring elements such as micro-switches, proximity sensors or even image monitoring devices may be provided to ensure a smooth flow of the welding device.
  • the welding electrode (position 26 of Fig. 2) is nachzutragen still that there the welding electrode is formed as a wheel electrode which can be rotated about a horizontal or vertical axis and thus used sequentially in a plurality of positions.
  • the welding electrode may be formed, for example, as a polygonal electrode wheel which has nests at angular intervals for receiving the respective blank.
  • eccentric loads may result, leading to uneven contact pressure in the contact surface. Uneven contact pressure can lead to a deterioration of the welding quality when large contact surfaces occur.
  • a clamping receptacle 36a or 34a is received for a pin electrode 26p or 28p.
  • the formation of the clamp receptacle 34a is shown on the lower electrode carrier 34. Adjoining the clamp receptacle 34a to the right and left to a clamping slot 34b, of clamping screws 34c is penetrated, so that the clamp receptacle 34a can be relaxed or narrowed. After wear of an electrode surface of the respective electrode pin can be post-processed and nachgeschoben.
  • the current flow through the pin electrodes is denoted by cf.
  • the pin electrodes shown in FIG. 8 in addition to equalizing the welding pressure, it is also ensured that the welding current, thanks to the geometric arrangement of the welding surfaces to the welding electrodes, thanks to the aligned arrangement of the cylindrical welding electrodes and thanks to the approximately centric arrangement of the welding electrodes in the electrode carriers has uniform current density over the entire contact surfaces.
  • the contact is, so to speak, in the range of the largest current density.
  • the feeding device which holds the contact metal blanks until they are clamped between the electrodes, makes it possible to dispense with special nests in the electrodes.
  • the insertion device according to the invention allows to position the contact metal blanks at any point of the welding electrode end faces and thus to take into account the demand for the most uniform current flow density.
