Definitions
- the present invention relates to a tensioning device, and in particular a multiple clamping device with at least a clamping module arranged on a base rail, the one slidably held on the base rail and fixable to it in different positions Basic element and a tensioning element attached to the basic element for clamping one workpiece against another the clamping module or stop module provided on the base rail is arranged displaceably, wherein the Clamping element held on the base element by a screw is and has a run-up slope, which at Tightening the screw cooperates with a counter surface, to the movement of the screw in a clamping movement implement the clamping element.
- Clamping devices of this type are in different Embodiments are known and are particularly based on NC Machining centers, drilling and milling machines, Coordinate grinding machines etc. used to simultaneously a large number of workpieces on a pallet, a plate or a machine table.
- the known multiple clamping systems are modular and include a base rail, usually a fixed one Stop module and several clamping modules provided are, each with a workpiece between two clamping modules or between a clamping module and the stop module can be excited.
- the clamping modules one on the market available multiple clamping system, of which the invention comes out, each have a basic element that the base rail slidably arranged and in different Positions can be locked, as well as a clamping element, that is movable along a slope on the base element is guided and for clamping or loosening workpieces movable by means of an Allen key is.
- the object of the invention is therefore a tensioning device of the type mentioned in such a way that while maintaining good functional accuracy easily and quickly can be converted.
- the Clamping element transversely to the guide direction of the clamping module and in particular in the axial direction of the screw actuating element arranged on the base element, by tightening the screw towards the Base rail is movable, and a parallel to the base rail jaw element movably arranged on the base element has, the actuator and Clamping jaw element are formed bevels that interact with each other to tighten the Screw the movement of the actuator into one movement to implement the jaw element.
- This configuration offers the advantage that the jaw element performs a pure tensioning movement, i.e. the clamping movements parallel to the base rail.
- the clamping jaw element expediently has one penetrated by the screw, in the direction of movement of the Clamping jaw element elongated through opening on, which is open to the basic element, so that the jaw element from the base element without loosening the screw can be removed to the side.
- This embodiment has the advantage that the jaw element exchanged easily and quickly can be.
- Locking means for example in the form of a spring-loaded Locking pin, which in a recess of the Interlocking jaw element engages, be provided.
- the ramp should be preferred Arranged at an angle of 45 ° to the base rail be, creating optimal path conditions during implementation the movement of the actuator in the movement of the jaw element can be reached and also it is also ensured that the jaw element does not stand out from the basic element.
- Another advantage is that a direct force curve from the actuating screw in the T-slot nut.
- a T-slot is formed, in which a T-slot nut is used, by means of a the basic element screwed screw attached to the base element and by tightening the screw with fixation the clamping module can be clamped against the base rail, and that the screw for fastening the clamping element the basic element, the clamping element and the basic element reaches through and is screwed into the T-nut.
- the fixation takes place of the basic element on the base rail by the T-slot nut by tightening the base element Screw is clamped to the base rail.
- the setup times are therefore compared to the known Clamping system in which the base element is fixed the base rail is done by four screws, comparatively low.
- the two screws are preferably parallel to each other and in particular perpendicular to the direction of guidance the T-slot aligned.
- a covering the screws Lid is arranged in which an opening is provided is through which the penetrating element Screw is accessible. This cover ensures that the facial expressions through which the basic element and the tensioning element can be actuated from contamination are protected and thus the clamping module is less susceptible against pollution-related faults.
- the T-slot nut is expediently transverse in the T-slot guided laterally to the guide direction, so that over the T-slot nut lateral positioning also takes place. Furthermore, can on the base element and the base rail interacting toothed strips can be provided, with which with a small pitch a reproducible positioning accuracy of the basic element in the guide direction the T-slot can be achieved.
- Figures 1 to 3 is an embodiment of an inventive Tensioner shown as it for example on NC-controlled machining centers, Drilling and milling machines, coordinate grinding machines etc. be used to simultaneously a variety of Workpieces on a pallet, plate or one Clamp machine table.
- a base rail 2 for example on a machine table can be attached in a stationary manner.
- the base rail 2 is horizontal, but it is also possible to arrange them diagonally or vertically.
- the base rail 2 has a T-groove 5 in its upper side in which the stop module 3 and the clamping modules 4 are slidably arranged.
- the clamping modules 4 each have an L-shaped base element 6, which via a T-slot nut engaging in the T-slot 5 7 is held on the base rail 2.
- the T-slot nut 7 is on the base element 6 by a screw 8 attached, the base element 6 approximately perpendicular to The direction of the T-slot 5 extends through and into the T-slot nut 7 is screwed.
- On the horizontal Leg of the L-shaped base element 6 is a jaw element 9 parallel to the guide direction of the T-slot 5, i.e. here in the horizontal direction, guided and points to the vertical leg of the base element 4 facing back an inclined surface 10, the is inclined at 45 ° to the base rail 2.
- On this ramp 10 is an actuator 11, the a corresponding 45 ° to the base rail 2 inclined Has ramp 12 and in the vertical direction on Basic element 4 is guided.
- the jaw element 9 and the actuating element 11 are fixed to the base element 6 by a screw 13, a bore 14 in the actuator 11th and one running parallel to the direction of guidance of the T-slot 5 Long slot 15 in the jaw element 9, the is open to the vertical leg of the base element 6, and the horizontal leg of the base element 4 reaches through and is screwed into the T-nut 7.
- the head of the screw 13 lies on the actuating element 11 on, so that this in the direction of the base rail 2 is depressed when the screw 13 is tightened being, this vertical movement of the actuator by the interaction of the two bevels 10, 12 in a horizontal clamping movement of the jaw element 9 is implemented.
- the elongated slot 15 in the jaw element 9 is therefore open to the vertical leg of the base element 6 held so that the jaw element 9 in a horizontal Direction can be subtracted from the base element 6, making retrofitting easier.
- Preventing unintentional loosening is, like in particular 4 and 5 is shown in the basic element 6 a spring pin 25 screwed in with a Recess in the jaw element 9 in locking engagement stands.
- the two screws 8, 13 of the clamping module 4 are as hexagon socket screws trained, and on that of the base rail 2 is the pioneering top of the clamping module 4 a cover 16 covering the two screws 8, 13 is attached, in which an opening 17 is provided through which the screw 13 for actuating the jaw element 9 is accessible for an Allen key.
- the lid 16 protects the facial expressions inside the Clamping module 4 against contamination.
- the clamping module 4 is fixed on the base rail 2, by the T-slot nut 7 by tightening the vertical leg of the base element 6 penetrating Screw 8 against the top of the T-slot 5 in the base rail is clamped, as can be seen in Figure 3 is, and can be reversed by loosening the Screw 8 are loosened again from the base rail 2, a slight loosening is sufficient to achieve this Basic element 4 during retrofitting processes along the base rail 2 to be able to move. To do this with high Repeat accuracy position the clamping module 4 exactly are on the top of the base rail and 6 toothed strips 18 on the underside of the base element, 19 provided for positioning the clamping module 4th can be brought into engagement with each other.
- the stop module 3 has a base body 20 which also via a T-slot nut 7 on the base rail 2 is fixable.
- the T-slot nut 7 is in this case two screws 21, 22, which the base body 20th reach through and screwed into the T-nut 7 are fixable.
- the two screws 21, 22 are also here protected by a cover 23 against contamination.
- the base body 20 also has on its underside a rack 24 on the rack 19 the base rail 2 can be brought into engagement with the stop module 3 to position exactly.
