Definitions

• the invention relates to a clamping device according to the preamble of patent claim 1.
• a clamping device of the type mentioned is known from DE 102 56 385 B3.
• This clamping device consists of a tensioning head piece, in which a linearly movable actuator is arranged with two mutually adjustable position sensors, which are designed to cooperate with two at a fixed distance from each other and stationary to the tensioning head piece arranged sensors.
• the linearly movable actuator of two parts and by means of a corresponding toothing variable in length (aus-) is formed, the position sensors are each arranged on a part and results by adjusting the parts to each other, the distance between the position sensors.
• This feature is also provided in a preferred embodiment of the invention, as explained below.
• the two sensors are arranged stationarily on a carrier element positioned in the tensioning head piece. To change the sensors, the entire clamping device must be taken apart.
• a tensioning device is known, which is provided in a known manner in the tensioning head piece with an actuator comprehensive actuating mechanism (in particular a so-called toggle mechanism) for pivotally actuating a clamping arm.
• the actuator is assigned to a drive, for example a so-called pneumatic drive, at the far end of the tensioner head piece.
• the actuator in the solution according to DE 196 16 441 Cl is integrally formed and also has only one position sensor.
• the two sensors are designed to be mutually adjustable within a cartridge which can be inserted into a slot on the tensioning headpiece.
• the invention has for its object to improve a clamping device of the type mentioned.
• a separate, externally accessible insertion opening is provided on the tensioning head piece for each sensor.
• the invention is characterized in particular by the departure from the usual carrier or cassette training towards a single positioning of the sensors.
• the particular advantage of the solution according to the invention consists in the fact that, despite sufficiently easy handling, the sensor system is overall significantly less expensive. Regarding the handling is to be noted that the sensors are practically only in case of damage or expand.
• the adaptation to different clamping requirements takes place by the adjustment of the position sensor to each other and accordingly in particular by length adjustment of the actuator, which, as explained above, formed in a preferred embodiment of the invention within the meaning of DE 102 56 385 B3 longer variable is.
• the use of so-called pneumatic sensors is possible, which consist in principle of small actuated by the positioners, acting as a switch way valves.
• FIG. 1 in perspective, the clamping device according to the invention with the tensioner head and
• FIG. 2 seen from the open side, the tensioning device according to FIG. 1.
• the tensioning device consists of a tensioning head piece 1, in which a linearly movable actuator 2 with two mutually adjustable position sensors 3, 4 is arranged, which with two at a fixed distance from each other and stationary (stationary) to the tensioning head piece 1 arranged sensors 5, 6 are formed cooperatively.
• a piston drive 22 pneumatic or hydraulic cylinder
• the actuator 2 and an associated actuating mechanism 16 are actuated.
• the two sensors 5, 6 in this case have an electrically operating, arranged in a small housing 9 sensor part and a freely bendable cabling part 10, which connects the sensors 5, 6 with a arranged on the tensioning head piece 1 connection adapter 15.
• the above-mentioned insertion openings 7, 8 on the tensioning head piece 1 are formed in a shape adapted to the housings 9 of the sensors 5, 6.
• the sensors 5, 6 or their housings 9 are associated with latching elements 24.
• variable-length actuator 2 a suitably dimensioned and to the insertion openings 7, 8 separate through-opening 11 is provided on the tensioning head piece 1, d. H. , the insertion openings 7, 8 are, seen in the axial or extension direction of the actuator 2, in front of and behind the slot-like passage opening 11, or in other words: The passage opening 11 is disposed between the two insertion openings 7, 8.
• regions of the sensors 5, 6 are each provided on two shell-like halves (half-shell elements 17) tensioning head piece 1 an externally accessible recess 12 which extend the access to the insertion openings 7, 8 and thus facilitate.
• These recesses 12 may also be connected longitudinally, d. H. form a channel (a depression) and thus also detect the passage opening 11.
• Opening 11 may be formed accessible from the outside via the recess 12, wherein the combined recess design is preferred for reasons to be explained.
• the recess 12 is basically designed so that in this a cover member 13 is used.
• the lid member 13 is designed to cover the wiring parts 10 of the sensors 5, 6 and thus this even in the recess 12 used.
• a passage opening for the wiring parts 10 from the sensors 5, 6 to the connection adapter 15 is optionally provided on the tensioning head piece 1 and / or on the cover element 13.
• the chuck head piece 1 is also provided with an interrupted by the elongated recess 12 Anflansch Structure 14, which is quasi a transverse to the head piece extended Breitnut, with the whole tensioning head piece 1 on a correspondingly profiled, not shown here carrier can be fastened ,
• the cover element 13 which may for example be formed from a suitable plastic, is shaped in cross-section such that it does not impede the flange surface 14 on the one hand and is provided on the inside with reinforcing elements 25 which extend into the passage opening 11 intervene. To fix the cover element 13, this can be latched in the tensioning head piece 1, as shown in FIG. 2, or it is held in the recess 12 with a suitable locking element.
• the actuator 2 is designed to be more variable and consists of two fixed, but releasably connectable parts 18, 19, for their fixed connection in the desired setting of a mutual toothing 21 a screw 20 with a groove-guided backdrop-like Gegenverschraubung 26 (see Figure 1). is provided.
• the position sensors 3, 4 are arranged as corresponding dimensioned projections 23 on the actuator 2 or on its parts 18, 19.
• the adjusting mechanism 16 does not necessarily have to be designed as a toggle mechanism as shown, but it can also be designed as a cam or tilting lever mechanism in the sense of DE 10 2004 007 465 A1 (FIGS. 3 and 4).
