Definitions

• the invention relates to an actuating device according to the preamble of patent claim 1.
• An actuator of the type mentioned is known from DE 1 183 204 A.
• This pivoting device consists of a pivotable in a first operating state about an axis (pivot axis) actuator (crank), which is rotationally connected to a tooth member (gear).
• the invention has for its object to improve a Betuschistsvor ⁇ direction of the type mentioned.
• an actuating device is to be created in which the actuator can be locked if necessary.
• the toothed member is formed blocked in a second operating state for prohibiting Schwenkbe ⁇ movement of the actuator with a movable ge ⁇ superimposed to the axis of catch member.
• tooth member is provided according to the invention that this is either as in DE 1 183 204 A as a complete (circular) gear or even as a sector-shaped tooth element (with arranged on its arc teeth), in particular depending on the targeted ⁇ pivoting range of the actuator.
• the locking member which - as well as the other components mentioned - are arranged in or on a housing, according to the invention erfin ⁇ tion characterized in that it is positively locked only in the second operating state with the tooth member, and thereby the locking of the actuator conditionally. Therefore it is particular ⁇ DERS preferably mounted in the direction of the axis of the actuator or of the tooth member displaceable in Gebäuse, so that an engagement of the locking member prevents the tooth member further rotational movement of the actuating member.
• the actuating device shown in the figures which is designed as a so-called tensioning or pivoting device, in particular for the automotive industry, consists of a in ei ⁇ nem first operating state (normal operation) ver ⁇ pivotable about an axis 1 actuator 2 (typically a clamping ⁇ or swivel arm on which further tools or the like can be fastened ⁇ be), which is rotationally connected to a tooth member 3.
• a tensioning or pivoting device in particular for the automotive industry, consists of a in ei ⁇ nem first operating state (normal operation) ver ⁇ pivotable about an axis 1 actuator 2 (typically a clamping ⁇ or swivel arm on which further tools or the like can be fastened ⁇ be), which is rotationally connected to a tooth member 3.
• axis 1 actuator 2 typically a clamping ⁇ or swivel arm on which further tools or the like can be fastened ⁇ be
• tooth member 3 typically a clamping ⁇ or swivel arm
• the tooth member 3 either as a circular gear (as Darge ⁇ asserted) or as a circular sector shaped tooth member (not illustrates Darge ⁇ ) may be madebil ⁇ det having disposed on its circular arc teeth. Also preferred is (also not shown expli ⁇ zit), that the axle 1 as a shaft is formed (for torque transmission ⁇ ), wherein the actuating member 2 and the dental element 3 rotationally connected to this shaft.
• the actuating transmission member 2 is rotationally connected to a rotatable in the first operating state about the axis 1 drive gear 13, which in turn is provided with a rack 14 provided with a drive piston ⁇ 15 operatively connected.
• Zvi ⁇ rule is disposed a transmission gear 16 to the drive gear 13 and the rack 14 for embedding ⁇ pound ung the transmission ratio.
• the tooth member 3 while a finer toothing and has a smaller diameter than the at ⁇ drive gear 13.
• the drive piston 15 is pneumatically or hydraulically operated in a known manner.
• the tooth member 3 in a second operating state to prevent a pivotal movement of the actuator 2 with a movably mounted to the axis 1 locking member 4 is formed blockable.
• the locking member 4 is formed in its position to the tooth member 3 for setting the first or second operating state ver ⁇ adjustable, wherein the operation of the locking member 4 in principle can be done either pneumatically, hydraulically or electrically.
• the locking member 4 shown in the figures is designed to be actuated pneumatically, which will be explained in more detail below ⁇ he.
• the locking member 4 has a toothed member 3 to form-fit matching teeth 5 and is formed as in a housing 6 of the actuator ver ⁇ displaceably mounted bolt. At one end of this bolt cooperating in the second operating state with the tooth member 3 toothing 5 is arranged.
• the other end of the bolt is designed as a piston rod 7 to a guided in a cylinder 8 of the housing 6 piston 9.
• the piston 9 is formed from two sides acted upon by a force. Be ⁇ particularly preferred is, as shown, provided that the piston 9 from one side with a fluid (typically, air or oil), and forms from the other side with a spring 10, in particular a helical compression spring, can be acted upon out ⁇ .
• a line 12 is arranged ausmündend on the cylinder 8 for supply and discharge of the fluid.
• the cylinder 8 with a housing 6 arranged on the (in particular screwed) cover 11 is closed out ⁇ forms.
• the actuating device works as follows: In Figure 1, the operating device is shown in the first Be ⁇ operating state, ie, the teeth 5 of the bolt or of the locking member 4 does not interfere with the teeth of the toothed member ⁇ . 3 Accordingly, via the drive piston 15, when this is moved by a corresponding pressurization in the image up, first the transmission gear 16 and thus also the drive gear 13 is rotated who ⁇ . Since further rotationally the actuator 2 is connected to the drive gear 13, thus an actuation of the drive piston 15 to a pivoting movement of the Actuate the ⁇ supply member 2. performs Depending on the size of the rack corresponding actuating ⁇ away selected 14, this results in a ent ⁇ speaking adjusting angle of the actuator. 2
• FIG. 1 The comparison of Figures 1 and 2 illustrates the function of the lock:
• a fluid has been introduced into the cylinder 8 via the line 12. If the valve shown on the right is closed, the fluid can no longer leave the cylinder. In addition, thus the position of the piston 9 and thus also of the bolt with the toothing 5 is defined.
• the line 12 is connected to the cylinder 8 such that a pressurization has the consequence that the piston 9 against the spring 11, which in turn is supported on the lid 11, is pressed.
• the actuating device according to the invention is in the first operating state ⁇ (normal operation).
• both the piston 9 of the locking member 4 and the drive piston 15 can be acted upon by corresponding valves or valve control with fluid.
• the He ⁇ invention encompasses also the option that the Betuschistsvor ⁇ direction is associated with a corresponding control of the fluid actuation of the pistons 9, 15 corresponding BEWE ⁇ supply plans can be controlled following as needed. LIST OF REFERENCE NUMBERS
