Definitions

  • the invention relates to a guide device for machine tools and the like and in particular for punching tools, consisting of at least one in a guide beech axially movably mounted guide column, the Guide column between an at least indirectly carrying the tool Machine tool part and at least indirectly supporting the workpiece Workpiece machine part extends and together with the guide bushing the mutual Relative movement of machine tool part and workpiece machine part leads in its axial direction, the guide column on one of the two Machine parts is fixed and the guide bush the other of the two Machine parts is assigned, the bearing of the guide column in the guide bush a mortise extending in its axial direction connected in parallel is, and wherein the tenoning the two machine parts at the end of said axial relative movement at least at the time of loading the Workpiece by the tool in its radial direction at least almost free of play locked.
  • Guide devices consisting of guide columns are used in a wide variety of ways Areas of application used to be relatively short strokes with high Leadership accuracy. They are usually stored in roller bearings, which leads to the accuracy of workpiece machining from the bearing play depends. Especially with the high precision punching tools, of which here The camp game is often exemplary but not exclusive still too large to meet the very high dimensional accuracy requirements. For this reason, in addition to the guiding devices, several Tappings distributed over the punching tool arranged at the time of The two act on the workpiece Guide machine parts with almost no play and lock them in the radial direction. This makes it possible to ensure that the tool is accurate to the workpiece by a millimeter loaded in the intended position so that the Workpieces also in several work steps arranged one behind the other Follow-up tool can be manufactured without deviation.
  • This object is achieved in that the mortise by Parts of the guide column and / or ⁇ bushing itself is formed, and that the Parts of the guide column and / or ⁇ bushing forming the mortise axially adjacent arranged to or coaxial with the bearing of the guide column in the guide bush is.
  • the bearing of the guide column forms a rough guide for the majority the mutual relative movement between machine tool parts and workpiece machine part, for example for opening the tool 10 - 100 mm wide after the punching process, while the aligned mortise in particular critical time when the workpiece is loaded by the tool over a stroke length of 2 - 3 mm is effective as a fine guide to the high To be able to ensure manufacturing accuracy.
  • Aligning the Tapping on the guide pillar also leads to a simplification in such a way that not in addition to all the guide columns distributed over the tool the corresponding guide bushes, the position of all the mortises in the machine tool part on the one hand and in the workpiece machine part on the other hand during production and assembly of the tool must be precisely coordinated; the position of the guide columns and the guide bushes is exact coordinated, so is the subsequent arrangement of the mortises Aligned to the guide columns and guide bushes almost no longer a problem.
  • the guide column in one Partial area has a cross-sectional widening which acts as a pin and which together with a part of the guide bushing that acts as a pin receptacle Mortise forms.
  • the peg and peg receptacle each in one piece with the guide column or guide bush, but also separately from these can be formed; only the assignment of the mortise is essential to the guide pillar or guide bush and the mutual coaxial or aligned arrangement.
  • the pin receptacle of the guide bushing is expediently opposite the the bearing surface for the guide column forming part of the guide bushing radially offset to the outside, so that the bearing of the guide column accommodates the pin the guide bushing is not applied. This can be done, for example, by a small paragraph, which ensures that the bearing parts are manufactured with high precision Do not damage the pin holder.
  • roller bearing preferably consists of a ball bearing, which is expedient has a ball cage between the guide column and guide bush is arranged, the balls the bearing surfaces of the guide column and the guide bushing.
  • the simplest is the cross-sectional enlargement forming the pin of the guide column formed by a circumferential radially projecting collar, the Outside diameter is adapted to the pin receptacle and the expedient compared to the bearing surfaces of the guide column at least by the thickness of the Storage, in particular the rolling bearing, protrudes radially outwards.
  • the invention can be used with any type of machine tool with short strokes as well as for example with spraying and Use die casting machines or other tools / machines that are high Accuracy requirements must meet. It is expressly emphasized that the invention also applies to these and similar other fields of application extends, the used in the claims for better readability Features such as “tool” and "workpiece” must be interpreted accordingly. So match these features, for example, in die casting machines the two Casting mold halves, which are guided by the guide columns and mortise and tenon must be brought into a precisely coordinated position.
  • a preferred embodiment is in the field of punching machines, so that the guide column expediently a punching tool supporting tool upper part of a punching machine assigned and fixed to this is that the guide bushing carries a sheet to be punched Cutting frame is assigned to a punching machine and fixed to this, and that the upper part of the tool with its guide column opposite the cutting frame with its guide bush a vertical lifting movement directed towards one another perform, and that the mortise at the end of the facing Lifting movement is effective at least in and especially shortly before Time at which the punching workpiece is loaded by the punching tool.
  • the axial stroke of the mortise i.e. the maximum depth of engagement of the mortise in the pin receptacle
  • this is of course the dimensions of the Workpiece dependent.
  • the axial mortising stroke is approximately 2 to 3 mm, during the total stroke of the tool from the closed position with effective mortising up to the open position in the order of between 10 and 100 mm.
  • Figure 1 is a guide device 1 according to the invention with a guide column 11, which is part of a machine tool (mainly not shown) is and for this purpose between a tool carrying the tool at least indirectly Machine tool part 2 and the workpiece at least indirectly load-bearing workpiece machine part 3 extends.
  • a punching tool is the machine tool part 2 in the form of a Tool upper part and the workpiece machine part 3 in the form of a cutting frame formed in addition to the lower pressure plate 6 attached below.
  • the guide column 11 which on the machine tool part 2 through a central collar 4th is screwed tight, leads together with one assigned to the workpiece machine part 3 Guide bush 5 the mutual relative movement of the machine tool part and workpiece machine part in the axial direction of the guide column.
  • the Guide bushing is in turn by crossing the lower pressure plate 6 in Workpiece machine part 3 fixed coaxially to the guide column 11.
  • a ball bearing 7 is arranged between the guide column and guide bush, that for the desired axial guidance during a guide stroke in the order of magnitude between 10 and 100 mm.
  • the bearing balls 7a are in one Ball cage 7b guided and roll on bearing surfaces 7c on the guide column 11 and bearing surfaces 7d on the guide bush 5.
  • a mortise 8 To the radial deviation of this axial guided stroke movement at least in Time of the application of the workpiece by the tool in an order of magnitude to hold between 2 and 30 thousandths of a millimeter Guide device 1 a mortise 8.
  • This mortise consists of one arranged on the guide column 11 pin 9 in the form of a radial Cross-sectional expansion and a pin receptacle provided on the guide bush 5 10, which is also opposed by a radial cross-sectional expansion of the bearing surface 7d is formed so as not to the balls 7a of the ball cage 7b and possibly damaged.
  • Figure 3 finally shows the guide device in the closed position:
  • the machine tool part 2 and the workpiece machine part 3 are on top of each other to driven into mutual contact, while simultaneously the guide pillar 11 is further immersed in the guide bush 5 with its lower free end, until the pin 9 the pin receptacle 10 over a pin stroke length of about 2 to 3 mm has applied.
  • This mentioned 2 to 3 mm pin stroke length must be like this be chosen large that the entire machining process - in this case Case of punching - with simultaneous engagement of the pin in the pin holder takes place, so that the radial deviation mentioned in the order of magnitude guaranteed by a few thousandths of a millimeter at least during the punching process is.
  • the present invention offers the advantage of being under extreme Space saving and low material costs provided Systems made up of guide columns and integrated mortises, which are highly precise Working of machine tools, die casting machines and similar devices enable with axial stroke without radial deviation.
