This has the disadvantage that the tensioning lever is articulated with the tensioning lever. This has the disadvantage that the tensioning saw only performs up-and-down movements for tensioning, so that adaptation to the position of the workpiece cannot be reliably achieved. At the end of the tensioning process, the drive motor must be switched off. Furthermore, this known tensioning device is provided with additional components such as an axially displaceable axial joint, an axial spring for the screw spindle, a movable axial bush, a safety limit switch, and the like.

A particular advantage resulting from this is that significant energy savings can be achieved when the machine is shut down during intermediate breaks. Also, for mass production, workpieces on pallets can be prepared for later processing. Furthermore, the advantage arises that a small compact construction method is obtained, and high tensioning forces can be achieved compared to known liquid-actuated tensioning devices. Also, a very wide variety of mechanical connection possibilities can be realized.

。Bearing is achieved by rolling bearings 6 and 7 in a guide housing 8 which threadably engages the intermediate piece 2. 1st
As can be seen, the swing pin 4 engages eccentrically in the flange disk 5 and moves about the central axis of this disk. A shaft 9 is fixed concentrically to the disc 5, which is provided with a kinematic thread 10 on the outside. An actuating rod 11 is screwed into this shaft 9 and can be displaced within the guide housing 8 . Furthermore, the shaft 9 has a reduced extension 12 with a transverse bore 12', in which a coupling element l3 in the form of a pin with a coupling spring 14 is arranged. This coupling member 13 engages inside the actuating rod 11 in an axially extending inner longitudinal groove 15 . Furthermore, the actuating rod 11 is provided with a lubrication aperture 16 in the center, and between the guide housing 8 and the actuating rod 11 there is also a scraping 17 .

たは他の緊張ヘッドが固定される。For stroke limitation, the outside of the actuating rod 11 is equipped with an axially extending outer longitudinal groove 18 in which a guide and locking bolt 19 is screwed laterally into the guide housing 8. engage. At the end of the actuating rod 11 a tensioning arm 20 or other tensioning head is fixed.
緊張腕の旋回運動の限定のため、ハウジング８の端側に
止めピン２１が取付けられる。To limit the pivoting movement of the tensioning arm, a stop pin 21 is mounted on the end side of the housing 8.

転運動を実施できる。When operating the device as a linear tension cylinder,
When the bolt 19 extending into the outer longitudinal groove 18 is screwed in and the shaft 9 is disengaged, the actuating rod 11 is displaced in the axial direction. The displacement movement is limited by the length of the book 18. When the device is to be operated as a pivot tensioner,
The bolt 19 is moved away so that the actuating rod 11 can perform a rotational movement.

作動棒１１は、被加工物に対して軸線方向運動を実施し
、これを固く緊張させる。The stop pin 21 serves both to ensure rotation of the actuating rod 11 and to limit the rotation angle of the tension arm 20. When the tensioning arm 20 additionally carries out a pivoting movement through a certain angle, which can optionally be adjusted by means of the stop pin 21, the following effect occurs. When the actuating rod 11 advances, after the bolt 19 is moved away, the switch of the rotary motor 1 is activated, and the six shafts 9 are connected to the actuating rod 11 by coupling devices 13 and 14 so that the actuating rod is moved in. and since the shaft 9 carries out a rotational movement, the tensioning arm 20 also carries out a corresponding rotational movement. The pivoting movement of the tensioning arm 20 is stopped by the stop pin 21 and a sliding connection is produced, with the stop pin 2I
takes over the action of the groove 18 and the bolt 19, so that the actuating rod 11 carries out an axial movement on the workpiece and tensions it tightly.
緊張を除く際には、モータ１が反対方向に駆動される。When releasing the tension, the motor 1 is driven in the opposite direction.

。That is, the actuating rod is advanced to release the workpiece. If the frictional force between the tensioning arm 20 and the workpiece is less than the coupling force of the coupling devices i1113, 14, the tensioning arm 20 can be pivoted to one of the stop pins 21. Thereafter, until the motor switch is switched off, the coupling device 13
, 14 causes an axial movement in the direction of tension relief.

is covered with a connecting member 13' having a corresponding inner contour and lengthened by a threaded pin 30, which is guided through the shoulder 29 of the actuating rod U. The device is directly tiAW4
When operating as a tensioner, the locking bolt l9 is screwed in and thus engages in the groove 18 (FIG. 3). By means of a driven shaft 9 with a threaded part 10, an actuating rod 11 is displaced in the axial direction.
