Description

Technical Field

[0001] The invention relates to a positioning device according to the preamble of claim 1 . Background Art

[0002] A positioning device of the type described at the outset is known from document DE 100 13 874 A1. The positioning device here has a pivotable clamping arm in the specific case, and the positioning device consists of a housing, an adjusting element supported in a linearly movable manner in the housing, a stop arranged on the adjusting element, and a counter-stop fixed in the housing and cooperating with the stop to limit the stroke length of the adjusting element, wherein an insertion opening for the counter-stop is provided on the housing. In this solution, the force introduced from the adjusting element via the stop into the counter-stop is introduced into the head part or the housing via a stroke limiter (see reference numeral 82 there) and a cover plate (see reference numeral 81 there). Summary of the invention

[0003] The object of the present invention is to improve a positioning device of the type mentioned at the outset. In particular, a positioning device is to be realized in which the forces from the adjusting element are better introduced into the housing or are transmitted to the housing.

[0004] This object is achieved by means of a positioning device of the type mentioned at the outset by means of the features specified in claim 1 .

[0005] According to the invention, it is provided that the counter-stop has two wedge-shaped elements which are adjustable relative to one another and can thus be fixed in the insertion opening.

[0006] In other words, the solution according to the invention is characterized in that the counter-stop for the stop arranged on the adjusting element is formed as a stable component by the combination of the insertion opening in the housing and two wedge-shaped elements which can be adjusted appropriately in the insertion openings. This combination results in a very stable solution, wherein the counter-stop can also be adjusted very easily if necessary, as will be explained in more detail below.

[0013] The positioning device shown in the drawings firstly comprises in a known manner a housing 1, an adjusting element 2 which is supported in a linearly movable manner in the housing 1, a stop 2.1 arranged on the adjusting element 2, and a mating stop 1.1 which can be fixed in the housing 1 and cooperates with the stop 2.1 to limit the stroke length of the adjusting element 2, wherein an insertion opening 1.2 for the mating stop 1.1 is provided on the housing 1.

[0014] Here, it is preferably provided that the adjusting element 2 is optionally designed to be driven electrically, pneumatically or hydraulically; Figure 1 and Figure 2 is shown below.

[0015] Furthermore, it is preferably provided that the stop 2 . 1 is optionally screwed into the adjusting element 2 and / or is designed to protrude from the adjusting element 2 in a pin-like manner.

[0016] Furthermore, it is preferably provided from a geometrical point of view that the main longitudinal axis of the counter-stop 1.1 is perpendicular to the main longitudinal axis of the adjusting element 2, but is laterally offset relative to the main longitudinal axis. Furthermore, it is preferably provided additionally or alternatively that the main longitudinal axis of the stop 2.1 is configured perpendicularly to the main longitudinal axis of the adjusting element 2 and intersects the main longitudinal axis.

[0017] It is now essential for the solution according to the invention that the counter-stop 1.1 has two wedge-shaped elements 1.1.1, 1.1.2 which are adjustable relative to one another and can thus be fixed in the insertion opening 1.2.

[0018] Here, a threaded element 1.1.3 is preferably provided for connecting the two wedge-shaped elements 1.1.1, 1.1.2. Furthermore, a threaded hole 1.1.1.1 is preferably provided on one of the two wedge-shaped elements 1.1.1, and a through hole 1.1.2.1 for the threaded element 1.1.3 is preferably provided on the other of the two wedge-shaped elements 1.1.2. From a geometric point of view, it is preferably applicable here that the threaded hole 1.1.1.1, the through hole 1.1.2.1 and the threaded element 1.1.3 are designed to have a common longitudinal axis.

[0019] As can be seen from the drawings, it is preferably provided that the threaded hole 1.1.1.1 is arranged on the thicker end of the wedge-shaped element 1.1.1. Furthermore, it is preferably provided that a threaded element retaining device 1.1.2.3 provided with a through hole 1.1.2.1 is arranged on the thinner end of the wedge-shaped element 1.1.2.

[0020] In order to utilize the so-called self-locking (see also:

[0021] https: / / de.wikipedia.org / w / index.php?title=Selbsthemmung&oldid= 224834918 ), in addition and with particular reference to Figure 4 Preferably, friction surface 1.1.1.2 provided on one wedge element 1.1.1 is designed to cooperate with friction surface 1.1.2.2 provided on another wedge element 1.1.2. It is also preferably provided that friction surfaces 1.1.1.2, 1.1.2.2 are designed to extend obliquely with respect to the longitudinal axis of threaded element 1.1.3.

[0022] In addition, if Figure 3 It can be seen particularly clearly that it is preferably provided that the counter-stop 1.1 has an approximately cylindrical outer contour overall. Accordingly, it is also preferably provided that the insertion opening 1.2 (on the housing 1) is designed as a cylindrical hole, see in particular Figure 2 Here, preferably, a plurality of insertion openings 1.2 for the counter-stops 1.1 are also provided on the housing 1.

[0023] As from Figure 1 and Figure 2 It can be seen that a slot 1.3 is preferably also provided on the housing 1, which slot extends with its longitudinal extension parallel to the main axis of the adjusting element 2 and ensures an unimpeded movement of the stop 2.1. In this case, a guide element 1.4 extending on both sides of the stop 2.1 is preferably arranged in the slot 1.3. The guide element 1.4 is preferably made of a harder material than the housing 1. In addition, in order to further increase stability, at least one through hole 1.4.1 for the counter stop 1.1 is preferably provided on the guide element 1.4.

[0024] Finally, the assembly and disassembly of the counter-stop 1.1 according to the invention is carried out as follows:

[0025] Step 1: Insert the preassembled counter-stop 1.1 into the insertion opening 1.2 until it stops. However, the threaded element 1.1.3 is not yet Figure 4 Screw in to the extent shown in .

[0026] Step 2: To produce a frictional connection between the friction surfaces 1.1.1.2, 1.1.2.2, one wedge element 1.1.1 is wedged against the other wedge element 1.1.2 by a force acting on the threaded element 1.1.3 (the circumference of the counter stop 1.1 is increased in this case). The force can be applied to the threaded element 1.1.3, for example, by impact with a hammer or a press.

[0027] Step 3: In order to eliminate possible interfering contours, the threaded element 1.1.3 is preferably screwed into the threaded hole 1.1.1.1 until the threaded element no longer protrudes from the insertion opening 1.2. The counterstop 1.1 according to the invention is now fixed and thus ready for use.

[0028] Step 4: If the positioning device is now to be adjusted within the scope of stroke length adjustment, the threaded element 1.1.3 is screwed in further, thereby moving the wedge element 1.1.1 in the direction of the threaded element holder 1.1.2.3 and releasing the friction lock between the friction surfaces 1.1.1.2, 1.1.2.2 (here the circumference of the mating stop 1.1 is reduced again).

[0029] Step 5: Finally, the impact can be stopped, for example by screwing the threaded element 1.1.3 or also by means of a so-called impactor (for this purpose, a Figure 1 The counter stop 1.1 is removed or knocked out of the housing 1 and readjusted if necessary.
