Definitions

  • the invention relates to a tool changing device in rotary hammers and kneaders according to the preamble of claim 1.
  • Rotary hammers and kneaders which operate according to the feed or plunge method, with two or more hammer plungers and jaws as forming tools in a tool guide with a front cover, in particular with jaw feed by wedge insertion.
  • the hammer jaws have so far been changed by hand, which is cumbersome and time-consuming and prevents efficient operation, especially when it comes to smaller series, which requires the tools to be repositioned more often, or for machining workpieces with several Gradations.
  • the tool changing device in rotary hammers and kneaders is characterized in that a swivel or lifting segment with juxtaposed receiving chambers with tool gripper and holder for the interchangeable tool sets - hammer jaws - swings into the workpiece feeder axis for tool change - Or is slidable, which swivel or lifting segment has a guideway in which the front cover, which is likewise pivoted or slidably engages, in such a way that it covers the hammer mechanism in the working position and releases it in the tool change position.
  • the tool grippers and holders of the receiving chambers in the swivel or lifting segment are assigned vertically pivotable actuating arms which insert or remove the selected tool sets - hammer jaws - from the tool guide into the corresponding receiving chamber after adjustment to the workpiece feeder axis.
  • a tool guide 2 is provided on the hammer head housing 1 in the hammer machine shown, which receives the hammer plunger 3 with hammer jaws 4 - here three each - with associated insertion wedges 5; the tool feeder axis is here at 6.
  • the structure and the mode of operation are described in detail in DE-PS 32 05 584.
  • the hammer mechanism on the hammer head housing 1 is preceded by a pivotable or displaceable front cover 9 and a pivoting or lifting segment; operable in the example as a swivel segment 10 by means of a rotary motor 10a.
  • the front cover 9 and the swivel segment 10 via a pin guide track 11, 12 in their swivel or. Sliding movement coupled together, such that the front cover 9 covers the hammer mechanism in the hammer head housing 1 in the working position and releases it in the tool change position.
  • the swivel or lifting segment 10 there are side by side along the guideway 12 on the lower edge receiving chambers 13 with tool grippers in Form of locking rockers 14 provided in associated tool holder housings 15.
  • An actuating arm 16 is assigned to each holder housing 15, which actuating arm 16 moves the selected tool sets in the form of hammer jaws 4 after adjustment to the tool feeder axis 6 from the tool guide 2 into the corresponding receiving chamber 13. spread.
  • the actuating arms 16 engage on the outside of the tool holder housing 15 by means of a pin slot guide 17 for retracting and extending at the receiving chambers 13, the actuating arm 16 engaging in the hook opening 20 from the piston tappet 18 of a cylinder drive 19 by means of a hook end 21 to pivot it.
  • the tool grippers in the form of latching rockers 14 are pivotably arranged in circumferential slots 22 of the respective tool holder housing 15 and engage via bevels 23 on the hammer jaws 4 with latching lugs 24 in blind holes 25 of the same (FIG. 4) for insertion and removal.
  • the latching rockers 14 engage at the end by means of pins 26 in oblique slots 27 of a driving piston 28 in the tool holder housing 15 and can be lifted out of their latching action with the hammer jaws 4 by means of an actuating plunger 29 that hits the end of a latching rocker 14.
  • the tool holder housing 15 also accommodate a counter-holder plunger 31 which is extended under spring action 30 and which is guided on the one hand at 32 in the housing 15 and on the other hand at 33 in the driver piston 28.
  • the actuating plunger 29 can be advanced via an end bevel 34 from a piston plunger 35 with a cylinder drive 36 arranged perpendicularly thereto with a counter bevel 37.
  • These insertion wedges 5 are movably suspended in their receptacles in accordance with the aforementioned DE-PS; these (5) here have side cams 38, which (38) each run in an inclined path 39 of the tool guide 2, so that they do not fall into the center when the hammer jaws 4 are removed and inserted, where they (5) otherwise introduce the would block changing hammer jaws 4.
