Description

Technical Field

[0001] This invention relates to a linear regulator, a positioning device, a positioning component, and a method for repairing a linear regulator. Background Technology

[0002] A drive for a spindle drive with a stop device is known from DE 10 2004 007 550 A1.

[0003] EP 1 1898 122A2 describes a regulating device for a linear regulator.

[0004] US2 497 424 discloses a stop device for a linear regulator.

[0005] DE 10 001 939 A1 describes an adjustment device for positioning a lens in a projector. The adjustment device has a lens support frame and a lens receiving frame for receiving the lens. The lens receiving frame can be adjusted relative to the lens support frame in opposite linear adjustment directions within certain limits. Here, an anti-locking nut is rotatably guided, on the one hand by a fine thread on a drive spindle and on the other hand by a coarse thread in a frame hole in a molded part of the lens receiving frame. Two stops of the clamp protrude into the threads of the molded part, and the anti-locking nut can be brought onto these two stops by a movement defined by the coarse thread for locking. In this state, the anti-locking nut driven by the fine thread moves the clamp and thus the lens receiving frame along the corresponding adjustment direction until the lens receiving frame enters a stopped state using one of the end stops of the lens support frame. The coarse thread prevents the anti-locking nut from locking during the adjustment movement. Summary of the Invention

[0006] The object of this invention is to provide a linear regulator that is advantageous in terms of reliable operation.

[0007] According to the present invention, a linear adjuster is provided, comprising: a spindle-spindle nut mechanism; a first adjusting portion having a first base at a first end of the linear adjuster and having a first stop device; and a second adjusting portion having a second base at a second end of the linear adjuster and having a second stop device, wherein the first end and the second end are arranged opposite to each other, and wherein the first adjusting portion and the second adjusting portion are movable relative to each other along the longitudinal axis of the spindle by means of the spindle-spindle nut mechanism. The first adjusting portion and the second adjusting portion are implemented such that when the first stop device and the second stop device are in a stop preparation state and the linear adjuster performs an inward movement decreasing the adjuster length or an outward movement increasing the adjuster length, and the first adjusting portion and the second adjusting portion are in a predetermined corresponding stop movement position relative to each other, the first stop device and the second stop device enter a stop state, in which the first stop device and the second stop device abut against each other with their mutually facing surfaces. In embodiments of the linear adjuster according to the present invention, the stop state is particularly defined such that, in the linear adjuster, the first stop device and the second stop device abut against each other with their mutually facing surfaces.

[0008] For this purpose, the linear adjuster has a fixing device that can have a stop preparation state and a stop release state, wherein the stop release state is set by loosening the mechanical fixation of the fixing device. In the stop preparation state, a first stop device is mechanically fixed to a first base or a second stop device is mechanically fixed to a second base. In a corresponding embodiment of the linear adjuster, the stop state occurs during the insertion or removal motion. According to one embodiment of the linear adjuster according to the invention, the linear adjuster is in the stop release state after the mechanical fixation of the fixing device is loosened, in which the adjusting portion can move relative to each other from the stop movement position during the insertion or removal motion using a spindle-spindle nut mechanism, or alternatively, move relative to each other during the insertion and removal motions.

[0009] In an embodiment of the linear regulator according to the invention, the linear regulator can be implemented such that, in the case of a stop state occurring during an inward movement with a decreasing regulator length, further inward movement is mechanically prevented from the stop position in the stop preparation state, and further inward movement is no longer possible and is mechanically locked, particularly by a stop portion. Alternatively or additionally, in an embodiment of the linear regulator according to the invention, the linear regulator can be implemented such that, in the case of a stop state occurring during an outward movement with an increasing regulator length, further outward movement is mechanically prevented from the stop position in the stop preparation state, and further inward movement is no longer possible and is mechanically locked, particularly by a stop portion.

[0010] In an embodiment of the linear regulator according to the invention, the linear regulator may be implemented such that the loosening of the mechanical fastening of the fixing device is defined by the following alternatives (F1), (F2), (F3), wherein, for the purpose of describing the invention, a first base or a second base is defined as a first fixing member, and a fixing member assigned to the first fixing member is defined as a second fixing member. When the first fixing member is the first base, the fixing member is a first stop device, or when the first fixing member is the second base, the fixing member is a second stop device, provided that in one embodiment the corresponding first fixing member and the corresponding second fixing member constitute a stop preparation state:

[0011] (F1) Mechanically decouple the first fixed component and the second fixed component, wherein a mechanical connection is still maintained, particularly the connection between the first and second fixed components, wherein such connection can be achieved by a rotary joint or a linear guide;

[0012] (F2) Establish the free mobility of the second fixed component relative to the first fixed component, wherein the second fixed component has no mechanical contact with the first fixed component and the second fixed component is free to move relative to the first fixed component;

[0013] (F3) Deform the second fixed member relative to the first fixed member, for example, by plastic or elastic deformation of the second fixed member when the second fixed member is formed of a plastically deformable material or an elastically deformable material.

[0014] In alternative solution (F1) using a rotary joint, the axially pivotable portion of the second fixed member is mechanically released and moved radially outward to move radially outward relative to the spindle axis to a stop-release state. In alternative solution (F2), the second fixed member can be removed radially outward relative to the spindle axis. Here, in one implementation, the release of the second fixed member can already be achieved by releasing the fastener. Furthermore, in another implementation, the release of the second fixed member can only occur after the additional removal of at least one portion of the second fixed member. In alternative solution (F3), the deformable portion of the second fixed member moves radially outward relative to the spindle axis.

[0015] In an embodiment of the linear regulator according to the invention, the linear regulator can be implemented such that, in a stop-ready state where the second fixing member is mechanically fastened or locked to the first fixing member and arranged in a positionally and orientationally fixed manner, one or both of the following events (A1) and (A2) occur:

[0016] (A1) When the linear regulator moves in with a decreasing regulator length, it enters the first stop state with the minimum regulator length stop state between the first and second adjustment sections;

[0017] (A2) When the linear regulator moves out with increasing regulator length, it enters the second stop state in the minimum regulator length stop state between the first and second regulating parts.

[0018] According to the invention, the first stop device is arranged and fastened, particularly in the stop preparation state, on the first base or the second stop device is arranged on the second base in a position or orientation fixed manner, and especially fastened by means of a corresponding fixing device. According to the invention, the linear regulator is implemented such that one or both of the following measures (B1) and (B2) can be performed using the linear regulator:

[0019] (B1) By moving the first stop device relative to the first base to the stop release state, the stop state between the first adjustment part and the second adjustment part is canceled, so that the stop state no longer exists. It can be specified that if event (A1) exists, the first adjustment part can perform a further moving-in movement relative to the second adjustment part, or if event (A2) exists, a further moving-out movement can be performed.

[0020] (B2) By moving the second stop device relative to the second base to the stop release state, the stop state between the first adjustment part and the second adjustment part is canceled, so that the stop state no longer exists. It can be specified that if event (A1) exists, the first adjustment part can perform a further moving-in movement relative to the second adjustment part, or if event (A2) exists, a further moving-out movement can be performed.

[0021] According to one embodiment of the invention, the second fixing member is arranged at least segmentally or completely outside the first fixing member, so that the second fixing member can be accessed from the outside and can also be manually and especially by means of a tool from the outside. That is, the second fixing member can be brought from the ready state or moved to the stop-release state by manual operation.

[0022] Each embodiment of the present invention can be configured such that the transition from the stop preparation state to the stop release state between the second fixed member and the first fixed member is performed by moving the second fixed member or at least one segment thereof relative to the spindle axis, wherein the linear adjuster can be implemented according to one or more of the following alternatives (C1), (C2):

[0023] (C1) In the stop preparation state, the corresponding second fixing member is fastened to the first fixing member by means of a fastening device, in particular by means of at least one mechanically adjustable connecting element, wherein the stop device housing of the corresponding second fixing member is connected to the base housing of the corresponding first fixing member, and is held in a tensioned or locked position by means of the connecting element in a state in which the first and second fixing members are biased, and wherein by changing the position of the connecting element to a movable state, in which the connecting element biases the stop device housing and the base housing less or no longer, that is, the second fixing member can be moved to the stop release state with relatively little force consumption, wherein such movement to the stop release state is done by pivoting or displacing the second fixing member relative to the first fixing member or by loosening the mechanical connection between the second fixing member and the first fixing member or optionally simply by removing the second fixing member from the first fixing member.

[0024] (C2) In the stop preparation state, the corresponding second fixing member is clamped to the first fixing member by a clamping device, for example by a form-fit connection, wherein the stop device housing of the corresponding second fixing member is connected to the base housing of the corresponding first fixing member, and wherein the second fixing member is moved to the stop release state by overcoming the clamping between the second fixing member and the first fixing member, in particular by pivoting or displacing the second fixing member relative to the first fixing member or by canceling the mechanical connection between the second fixing member and the first fixing member, and optionally only by removing the second fixing member from the first fixing member.

[0025] In this paper, loosening the mechanical connection between the second fixing member and the first fixing member can in particular mean that the second fixing member can be separated from the first fixing member with less force and especially manual force and can be removed from the range of movement of the first fixing member.

[0026] In an embodiment of the linear regulator according to the invention, the linear regulator can be implemented such that, in the stop preparation state, the second fastening member is mechanically or fastened by means of a fixing device and is fixed in position and orientation on the first fixing member, wherein, in order to achieve the stop release state, the fixing device is loosened and the second fixing member is mechanically released to move radially outward relative to the main shaft axis away from the first fixing member to the stop release state.

[0027] In an embodiment of the linear regulator according to the invention, the linear regulator can be implemented such that the second fixed member and, for example, the first stop device have a first spacer and at least one movable stop portion, wherein the first spacer protrudes toward the second end in a direction along the longitudinal axis of the main shaft away from the first fixed member and, for example, the first base, and the first spacer has a proximal end section, a distal end section, and a connector connecting the proximal end section and the distal end section, and wherein the second fixed member and, for example, the first stop device are implemented using one or both of the following alternatives:

[0028] (m) A proximal movable stop portion is formed on the proximal end section, which extends radially from the first stop device relative to the longitudinal axis of the main shaft.

[0029] (n) A distal movable stop portion is formed on the distal end section, which extends radially from the first stop device relative to the longitudinal axis of the main shaft.

[0030] In an embodiment of the linear regulator according to the invention, the second fixing member and, for example, the first stop device may be formed as a clamp, a bridge, or an arch.

[0031] In an embodiment of the linear regulator according to the invention, the linear regulator can be implemented such that the fixing device is configured on the proximal end section.

[0032] In an embodiment of the linear regulator according to the invention, the linear regulator may have a first base as a first fixed member and a first stop device as a second fixed member, wherein the second stop device arranged on the second base has a second spacer and a complementary stop portion, wherein the second spacer protrudes toward a first end in a direction away from the second base along the longitudinal axis of the main shaft, and the second spacer has a connecting section, a stop section, and a connector connecting the connecting section and the stop section, the connecting section being anti-rotationally connected to the second base.

[0033] In these embodiments, the complementary stop portion can be arranged on the stop section and extend radially outward from the stop section relative to the longitudinal axis of the main shaft. When a distal movable stop portion is formed on the distal end section, the distal movable stop portion extends radially from the distal end section of the first stop device relative to the longitudinal axis of the main shaft, so that in the stop state where the linear regulator is at its maximum regulator length, the complementary stop portion and the distal movable stop portion overlap and abut against each other in the radial direction.

[0034] In an embodiment of the linear regulator according to the invention having a second spacer arranged on a second stop device, the second spacer may be configured as a tube.

[0035] According to one aspect of the invention, a positioning device is provided, having a linear regulator formed according to one embodiment of the linear regulator according to the invention. Here, it can be particularly specified that the application component can be coupled to one end of the linear regulator, particularly by means of a connecting device, and the application component can be coupled to the other end, particularly by means of a connecting device.

[0036] According to one aspect of the invention, a positioning assembly is provided having at least two, and in particular six, linear adjusters, each according to one of the embodiments of the linear adjuster according to the invention, wherein at least two linear adjusters are arranged such that they extend relative to each other along their main longitudinal axis, wherein on one side of the positioning assembly, at least two linear adjusters are each coupled to an application component, and on a second side of the positioning assembly disposed opposite to the first side of the positioning assembly relative to the main longitudinal axis, at least two linear adjusters are coupled to another application component or can abut against a reference surface.

[0037] According to one aspect of the invention, the application of at least two linear adjusters according to one embodiment of the linear adjuster according to the invention is proposed, wherein the at least two linear adjusters are arranged such that they extend relative to each other along their main longitudinal axis, wherein on one side of the positioning assembly, the at least two linear adjusters are coupled to the application component, and on a second side of the positioning assembly which is arranged opposite to the first side of the positioning assembly relative to the main longitudinal axis, the at least two linear adjusters are coupled to another application component or abut against a reference surface.

[0038] According to one aspect of the invention, a method is provided for a linear regulator according to one embodiment of the linear regulator according to the invention, wherein, in a stop preparation state, a first stop device is fixed to a first base or a second stop device is fixed to a second base by means of a fixing device, wherein in the stop preparation state, the stop state occurs during a movement in or out, wherein the method comprises the following steps:

[0039] The fixing device is released and the first stop device is moved relative to the first base or the second stop device is moved relative to the second base by a moving component that moves in the opposite direction to the stop adjustment movement, so that the linear regulator is in the stop release state;

[0040] The adjusting parts are moved relative to each other during the insert and remove movements using the spindle-spindle nut mechanism from the stop position.

[0059] The linear adjuster 1 provided according to the present invention is implemented as a variable-length adjusting device, having a spindle-spindle nut mechanism 2 and a first stop device 30 and a second stop device 40. Here, it can be specified that the linear adjuster 1 is used to set the adjuster length between the minimum and maximum adjuster lengths when the linear adjuster 1 does not have the first stop device 30 and the second stop device 40, or to set time derivatives such as speed and acceleration that depend on the current adjuster length. The spindle-spindle nut mechanism 2 has a spindle 3 extending along the longitudinal axis L3 of the spindle and a spindle nut 5 supported by the spindle thread 4 of the spindle 3. When the spindle 3 and the spindle nut 5 rotate relative to each other, the spindle 3 and the spindle nut 5 move relative to each other along the longitudinal axis L3 of the spindle. The linear adjuster 1 has a first adjusting portion 10 and a second adjusting portion 20, which can enter different adjusting states due to the rotation of the spindle 3 and the spindle nut 5 relative to each other via the spindle-spindle nut mechanism 2 moving relative to each other along the longitudinal axis L3 of the spindle.

[0060] Here, when the first stop device 30 and the second stop device 40 are not present on the linear regulator 1, the linear regulator 1 may have an adjustment state between the following extreme adjustment states:

[0061] (a) Shortest adjustment state, in which the relative position of the spindle 3 and the spindle nut 5 produces the minimum adjustment length of the linear adjuster 1, i.e. the minimum shift-in adjustment state;

[0062] (b) Maximum adjustment state, in which the relative position of the spindle 3 and the spindle nut 5 produces the maximum adjustment length of the linear adjuster 1, i.e. the maximum displacement adjustment state.

[0063] The shortest adjustment state or the maximum adjustment state can be limited or set by the corresponding design of the end of the spindle thread 4 or the corresponding design of the movement stop of the spindle nut 5 on the spindle thread 4.

[0064] The linear adjuster 1 may itself have a motor 7, which is an integral part of the linear adjuster 1. This motor 7 drives the spindle-spindle nut mechanism 2, thereby causing the spindle 3 and spindle nut 5 to rotate relative to each other to adjust the length of the linear adjuster 1. Here, the linear adjuster 1 can be implemented such that the motor 7 either rotates the spindle 3 or the spindle nut 5. The motor 7 drives the spindle-spindle nut mechanism 2 based on receiving an adjustment command. The adjustment command is generated in the control or adjustment device and defines the target movement or target adjuster length of the motor 7, or its time derivative.

[0065] According to another embodiment, the linear adjuster 1 itself does not have a motor as a component of the linear adjuster 1, but is adjusted externally, particularly by adjusting the position of the adjusting parts 10, 20 or the rotational position of the end segments 1a, 1b relative to each other by an external adjusting device, or by changing the adjustment state of the spindle-nut mechanism 2, i.e., the spindle 3 or the spindle nut 5. For example, it can be specified that the relative position of the adjusting parts 10, 20 is adjusted by the linear adjuster 1 according to the invention or according to the prior art, which has a motor 7, and its first adjusting part is coupled to the first adjusting part 10, and its second adjusting part is coupled to the second adjusting part 20. Here, it can be particularly specified that the spindle 3 is anti-rotationally supported on the first base 11, and the spindle nut 5 is anti-rotationally supported on the second base 21.

[0066] The first adjustment portion 10 has a first base 11 disposed on a first end E1 of the linear regulator 1 and a first stop device 30. The second adjustment portion 20 has a second base 21 disposed on a second end E2 of the linear regulator 1 and a second stop device 40. The first base 11 forms a first end segment 1a of the linear regulator 1, and the second base 21 forms a second end segment 1b of the linear regulator 1.

[0067] In the illustrated embodiment of the linear adjuster 1, the first base 11 may have a first base bottom 15 or a first base bottom portion, which is cup-shaped with a base plate and a wall segment 16 extending around the longitudinal axis L3 of the main shaft toward the second end E2. Alternatively, the first base bottom 15 or the first base bottom portion may also be integrally formed as a plate. Here, a cylindrical extension segment 17 is tightly attached to the first base bottom 15, more specifically to its end facing the second end E2, which continuously extends around the longitudinal axis L3 of the main shaft and extends from the first base bottom 15 toward the second end E2. The extension segment 17 may also be configured as a mesh. Alternatively, the extension segment 17 may be bifurcated with at least two branches. The first base bottom 15 and the extension segment 17 may also be formed in one piece or made from one piece. All embodiments of the linear adjuster 1 may also be formed without the extension segment 17.

[0068] In the illustrated embodiment of the linear regulator 1, the motor 7 is housed and secured or clamped by the peripheral wall of the extension segment 17. Alternatively, the motor 7 may be fastened and secured to the extension segment 17, the bottom of the first base 15, or the bottom portion of the first base by means of at least one connecting element or by means of adhesive. Alternatively, the motor 7 may also be fastened to the bottom of the first base 15 or optionally to the peripheral wall segment 16.

[0069] The first end segment 1a extends from the bottom 15 of the first base in a direction oriented away from the second end segment E2. However, the linear regulator 1 can also be configured without the first end segment 1a. For example... Figures 1 to 10 As shown, the first end section 1a can be formed as a first support device 12 for supporting or coupling the linear regulator 1 to the first application component.

[0070] The aforementioned variant of the first substrate 11 can be implemented in all embodiments of the linear regulator 1.

[0071] In the illustrated embodiment of the linear regulator 1, the second base 21 has a second base bottom 25 or a second base bottom portion, which is cup-shaped with a base plate and has a wall segment 26 extending toward the first end E1 about the longitudinal axis L3 of the main shaft. Alternatively, the second base bottom 25 or the second base bottom portion may also be formed as a plate. The second base bottom 25 or the second base bottom portion and the wall segment 26 may be formed in one piece. They may also be made in one piece or fastened together as separate components. All embodiments of the linear regulator 1 may also be formed without the wall segment 26.

[0072] The second end segment 1b extends from the bottom 25 of the second base in a direction oriented away from the first end segment E1. However, the linear regulator 1 can also be configured without the second end segment 1b. Figures 1 to 9 As shown, the second end section 1b can be configured as a second support device 12 for supporting or coupling the linear regulator 1 to the second application component.

[0073] The aforementioned variant of the second substrate 21 can be implemented in all embodiments of the linear regulator 1.

[0074] The first stop device 30 extends from the first base 11 along the longitudinal axis L3 of the main shaft toward the second end E2. Figures 1 to 10 In this embodiment, the first stop device 30 is formed in the shape of a clamp or a bridge. The first stop device 30 can be anti-rotationally or fixedly supported on the first base 11 in the circumferential direction around the longitudinal axis L3 of the main shaft.

[0075] The second stop device 40 extends from the second base 21 toward the first end E1 along the longitudinal axis L3 of the main shaft. For example... Figures 1 to 10 As shown, the second stop device 40 is anti-rotatably or fixedly fastened to the second base 21, and particularly to the wall section 26, in a circumferential direction surrounding the longitudinal axis L3 of the main shaft. Here, the second stop device 40 is implemented as a cylindrical section that extends continuously around the longitudinal axis L3 of the main shaft and extends from the bottom 25 of the second base toward the second end E2. Alternatively, the second stop device 40 may also be formed in a mesh shape. Alternatively, the extension section 17 may also be formed in a rod shape or in a forked shape with at least two branches. Such variations of the second stop device 40 can be implemented in all embodiments of the linear regulator 1.

[0076] like Figure 1 and Figure 2 As shown, each embodiment of the linear regulator 1 according to the invention can be implemented such that the linear regulator 1 has a first rotary bearing D1 supported in a first support device 12 to couple the first base 11 to the first application component. Alternatively or additionally, as Figure 1 and Figure 2 As shown, each embodiment of the linear regulator 1 according to the invention can be implemented such that the linear regulator 1 has a second rotary bearing D2 supported in a second support device 22 to couple the second base 21 to the second application component. Figure 1 and Figure 2 As shown, the first support device 12 and the first rotary bearing D1 can constitute the first connecting device 13, and the second support device 22 and the second rotary bearing D2 can constitute the second connecting device 23. Here, the first support device 12 and the second support device 22 are arranged anti-rotationally relative to each other, so that the first base 11 and the second base 21 are also arranged anti-rotationally relative to each other.

[0077] Each of the embodiments of the linear regulator 1 according to the present invention can be implemented such that either the first support device 12 or the second support device 22 is absent, or neither support device 12, 22 is absent.

[0078] The spindle 3 is supported on the first base 11, and the spindle nut 5 is supported on the second base 21. According to the present invention, the following implementation scheme can be provided:

[0079] (R1) The spindle 3 is rotatably supported on the first base 11 and fixedly supported on the first base 11 along the longitudinal axis L3 of the spindle, and the spindle nut 5 is anti-rotationally supported on the second base 21;

[0080] (R2) The spindle 3 is anti-rotationally supported on the first base 11, and the spindle nut 5 is rotatably supported on the second base 21 relative to the second base 21 and fixedly supported in the direction of the longitudinal axis L3 of the spindle.

[0081] In the case where the linear regulator 1 has a motor 7, the motor 7 can be integrated into the linear regulator 1 in implementation (R1) such that the motor 7 drives the spindle 3 and rotates the spindle 3 to change the adjustment state of the linear regulator 1. Here, the motor 7 can be supported on the first base 11. This embodiment of the linear regulator 1... Figure 4 As shown in the diagram. Alternatively, the motor 7 may be supported on the second base 21. In the case where the linear adjuster 1 has a motor 7, the motor 7 may be integrated into the linear adjuster 1 in implementation (R2) such that the motor 7 drives the spindle nut 5 and rotates the spindle nut 5 to change the adjustment state of the linear adjuster 1. Here, the motor 7 may be supported on the second base 21 or alternatively supported on the first base 11. In another embodiment, the alternatives described for implementations (R1) and (R2) may also be combined with each other. In the embodiment described for this purpose, it may be particularly specified that the end segments 1a, 1b are supported relative to each other in a rotationally resistant manner by external supports or application components. Alternatively, the end segments 1a, 1b may be supported rotatably relative to each other by external supports or application components.

[0082] Both the first adjustment portion 10 and the second adjustment portion 20, or one of the adjustment portions 10 and 20, can be configured as a support leg. In the case of such a support leg, the corresponding support device 12 or 22 is implemented as a foot portion or abutment portion. Therefore, the linear adjuster 1 can be placed on the bottom or reference surface, such as the surface of a table or laboratory apparatus, or arranged or mounted on a reference component, while the application component can be mounted or coupled to the corresponding other of the two adjustment portions 10 and 20, or the application component can be abutted against the corresponding other of the two adjustment portions 10 and 20 to move the application component relative to the bottom or reference surface.

[0083] In all embodiments of the present invention, the application component can generally be a functional component that is adjustable relative to the bottom or reference surface, such as a sensor, a mirror, or a tool.

[0084] According to the present invention, the linear adjuster 1 can be configured as a positioning device. The positioning device may, in particular, have a first connecting device 13 and a second connecting device 23. Furthermore, the positioning device may have a motor 7, which is integrated into the linear adjuster 1 according to the implementation described herein. Additionally, the linear adjuster 1 may have a control interface functionally connected to the motor 7, which transmits an adjustment command or target signal corresponding to a target adjustment state to the motor 7, wherein the motor 7 actuates the spindle-spindle nut mechanism 2 based on the target signal, causing the linear adjuster 1 to adjust in the direction of the target adjustment state, and in particular to an adjustment state close to the target adjustment state. The target signal may be transmitted to the control interface, for example, by manual actuation of an input device or by an external controller functionally connected to the control interface. The control interface may be functionally connected to at least one application component.

[0085] Typically, the linear adjuster 1 according to the invention, or a plurality of linear adjusters 1 according to the invention, can be arranged between and supported on two application components, or between one application component and a reference surface or reference device. Here, the distance or position between the two application components can be set by setting the adjuster length of at least one linear adjuster 1. According to the invention, the reference surface or reference device can be understood as a surface or device that cannot be adjusted in position and orientation using the linear adjuster 1, but can be adjusted relative to the application component in its orientation or position, or in both orientation and position.

[0086] According to the invention, at least two linear adjusters 1 can also form a positioning assembly according to the embodiments described herein. Here, the at least two linear adjusters 1 can be arranged such that they extend relative to each other along their main longitudinal axis L3. On one side of the positioning assembly, for example, where at least two linear adjusters 1 may be arranged, the at least two linear adjusters 1 are coupled to an application component, and on a second side of the positioning assembly, opposite the first side of the positioning assembly to the main longitudinal axis L3, the at least two linear adjusters 1 are coupled to another application component or abut against or connected to a reference surface. Here, at least one, or multiple, or all of the linear adjusters 1 may have the aforementioned control interface. The positioning assembly may also have an external controller that controls at least one control interface using a target signal. Here, the linear adjusters 1 of the positioning assembly may be arranged on the bottom or reference surface or mounted on a reference component or application component, with the first or second adjustment portion 10, 20, and optionally another application component may be mounted, coupled, or abut against the corresponding other of the two adjustment portions 10, 20.

[0087] For example, the positioning assembly or multiple linear adjusters 1 may be configured as a parallel kinematic mechanism having at least two linear adjusters 1, one or more of the embodiments of the invention described herein. Here, it may be particularly specified that the longitudinal axes L3 of the main shafts of the at least two linear adjusters 1 extend parallel to each other or at an angle to each other, such that the angle between the longitudinal axes L3 of the main shafts of the linear adjusters 1 and each other is a maximum of 45 degrees. In particular, the positioning assembly may have three linear adjusters 1, one or more of the embodiments of the invention described herein, and be configured as a so-called three-bar linkage (Tripod). Furthermore, the positioning assembly may preferably have six linear adjusters 1, one or more of the embodiments of the invention described herein, and be configured as a so-called six-bar linkage (Hexapod).

[0088] Based on the relative positions of the two adjustment parts 10, 20 with respect to each other, the linear regulator 1 in the adjustment state has an regulator length LV, which is generated as the distance between the length endpoints by the length endpoints at the corresponding end segments 1a, 1b of the two end segments of the linear regulator 1.

[0089] The first stop device 30 and the second stop device 40 are typically designed such that they perform a stop adjustment movement relative to each other and can enter a stop state in which at least one abutting surface of the first stop device 30 and at least one abutting surface of the second stop device 40 abut against each other when the linear regulator 1 performs a move-out movement to increase the regulator length LV. In the stop state, the first adjustment portion 10 and the second adjustment portion 20 are in a stop movement position relative to each other, predetermined by the position and shape of the stop devices 30 and 40, in which the abutting surfaces of the first stop device 30 and the second stop device 40 abut against each other, and in this stop movement position, the regulator length LV has a maximum stop regulator length Lmax. This adjustment state... Figure 4 As shown in the image.

[0090] Alternatively or additionally, the first stop device 30 and the second stop device 40 may generally be designed such that they perform a stop adjustment movement relative to each other and can enter a stop state in which at least one abutting surface of the first stop device 30 and at least one abutting surface of the second stop device 40 abut against each other when the linear regulator 1 performs a moving movement to reduce the regulator length LV. In the stop state, the first adjustment portion 10 and the second adjustment portion 20 are in a stop movement position relative to each other, predetermined by the position and shape of the stop devices 30 and 40, in which the abutting surfaces of the first stop device 30 and the second stop device 40 abut against each other, and in this stop movement position, the regulator length LV has a minimum stop regulator length Lmin. This adjustment state... Figure 5 As shown in the image.

[0091] exist Figures 1 to 10 The following embodiment of the linear regulator 1 is shown, wherein the following two regulation states (i) and (ii) can occur:

[0092] (i) Figure 4 and Figure 9 The maximum regulator length stop state shown is in which the linear regulator 1 has a stopped maximum regulator length Lmax, wherein the maximum regulator length stop state occurs and thereby stops the outward movement of the linear regulator 1.

[0093] (ii) Figure 5 and Figure 10 The minimum regulator length stop state is shown. In this minimum regulator length stop state, the linear regulator 1 has a stop minimum regulator length Lmin, wherein the minimum regulator length stop state occurs and thereby stops the moving motion of the linear regulator 1.

[0094] In all embodiments of the invention, instead of this, the linear regulator 1 may be designed with a first stop device 30 and a second stop device 40 such that only one of the two stop states (i) and (ii) occurs.

[0095] exist Figure 3 and Figure 8 The diagram illustrates the intermediate stop state, i.e., the position where... Figure 4 or Figure 9 Maximum regulator length stop state and Figure 5 or Figure 10 The stop state between the minimum regulator length stop state.

[0096] exist Figure 4 and Figure 5 as well as Figure 9 and Figure 10 In this embodiment, the first stop device 30 is implemented such that it has two abutment surfaces spaced apart from each other on the longitudinal axis L3 of the main shaft. Each abutment surface provides one of the stop states (i) and (ii) as an event that can occur.

[0097] In the embodiment of the invention shown in the figure, the first stop device 30 has a first spacer 34 and at least one movable stop portion. Here, the first spacer 34 protrudes from the first base 11 toward the second end E2 along the longitudinal axis L3 of the main shaft, and the first spacer 34 has a proximal end section 31, a distal end section 32, and a connector 33 connecting the proximal end section 31 and the distal end section 32. The proximal end section 31 is disposed relatively close to the first base 11 or the first end E1, and the distal end section 32 is disposed relatively away from the first base 11 or the first end E1.

[0098] In an embodiment of the linear regulator 1 according to the invention, the first stop device 30 may be implemented, in particular, according to one of alternatives (m) and (n):

[0099] (m) A proximal movable stop portion 35 is formed on the proximal end section 31, which extends radially from the first connector 33 relative to the longitudinal axis L3 of the main shaft.

[0100] (n) A distal movable stop portion 36 is formed on the distal end section 32, which extends radially from the first connector 33 relative to the longitudinal axis L3 of the main shaft.

[0101] In the embodiments of the present invention shown in the figure, not only implementation scheme (m) but also implementation scheme (n) are given. In alternative embodiments of the present invention, it may be specified that implementation scheme (m) or (n) does not exist, that is, only implementation scheme (m) or implementation scheme (n) exists.

[0102] Here, the proximal movable stop portion 35 can be implemented as a transition member extending radially between the first base 11 and the first connector 33. In the illustrated embodiment, the proximal movable stop portion 35 and the distal movable stop portion 36 each extend radially from the first connector 33 along the longitudinal axis L3 of the main shaft.

[0103] The first spacer 34 can be implemented, in particular, as a clamp or bridge shape, i.e., not in a tubular form and circumferentially around the longitudinal axis L3 of the main shaft. Here, the length of the first spacer 34 extending along the longitudinal axis L3 of the main shaft can be 1.2 times greater than the average width perpendicular to that length and in the radial direction relative to the longitudinal axis L3 of the main shaft. Alternatively, the first spacer 34 can be tubular and circumferentially around the longitudinal axis L3 of the main shaft. Here, the first spacer 34 can have the features of the second stop device 40 described herein.

[0104] In each embodiment of the linear regulator 1 according to the invention, as shown, the second stop device 40 may have a second spacer 44 and a complementary stop portion 45. Here, the second spacer 44 protrudes toward the first end E1 in the direction of the longitudinal axis L3 of the main shaft away from the second base 21. The second spacer 44 has a connecting section 41, a stop section 42, and a connecting member 43 connecting the connecting section 41 and the stop section 42, the connecting section 41 being rotatably connected to the second base 21. As shown, the second spacer 44 may be configured, in particular, as a tubular shape.

[0105] In the embodiment of the linear adjuster 1 shown in the figure, the complementary stop portion 45 may be an edge segment of the stop segment 42, wherein the edge segment is oriented toward the first end E1 along the longitudinal axis L3 of the main shaft. The complementary stop portion 45 moves between the proximal movable stop portion 35 and the distal movable stop portion 36 along the longitudinal axis L3 of the main shaft between adjustment states (i) and (ii). Alternatively or additionally, the complementary stop portion 45 may be arranged on the connector 43 and in this case extend radially from the stop segment 42 relative to the longitudinal axis L3 of the main shaft. Here, the direction in which the complementary stop portion 45 extends radially from the stop segment 42 relative to the longitudinal axis L3 of the main shaft is opposite to the direction in which the proximal movable stop portion 35 and the distal movable stop portion 36 extend from the first stop device 30.

[0106] In the embodiment of the linear regulator 1 shown in the figure, the proximal movable stop portion 35 has a proximal abutment surface 35a, and the distal movable stop portion 36 has a distal abutment surface 36b, wherein the proximal abutment surface 35a and the distal abutment surface 36a are oriented toward each other. Alternatively, the proximal abutment surface 35a and the distal abutment surface 36a may be formed on the first spacer 34 or the connector 35. In the embodiment of the linear regulator 1 shown in the figure, the complementary stop portion 45 has a first abutment surface 45a and a second abutment surface 45b, which are oriented relative to each other. In the adjustment state (i), the second abutment surface 45b of the complementary stop portion 45 and the distal abutment surface 36a of the distal movable stop portion 36 abut against each other. In the adjusted state (ii), the first abutting surface 45a of the complementary stop portion 45 and the proximal abutting surface 35a of the proximal movable stop portion 35 abut against each other.

[0107] In embodiments where feature (n) is absent in the linear regulator 1, the linear regulator 1 can be implemented without the second abutment surface 45b of the complementary stop portion 45, and particularly without the complementary stop portion 45. Here, the first abutment surface 45a of the complementary stop portion 45 can be implemented as the surface or edge surface of the second stop device 40 facing the first end segment 1a or the first end E1. In embodiments where feature (m) is not constituted in the linear regulator 1, the linear regulator 1 can be implemented without the proximal abutment surface 35a.

[0108] According to the present invention, the linear regulator 1 may also have a plurality of first stop devices, namely, first stop devices disposed on the first end E1 of the linear regulator 1. Here, each of the plurality of first stop devices is implemented according to one of the implementation schemes described herein.

[0109] exist Figures 6 to 10 In the embodiment of the linear regulator 1 shown, two first stop devices are arranged, indicated by reference numerals "30" and "60". In this embodiment, the first stop devices 30 and 60 are implemented identically to each other and arranged opposite each other relative to the longitudinal axis L3 of the spindle. Alternatively, the first stop devices 30 and 60 are each implemented according to one of the variations described herein.

[0110] According to the present invention, as shown in the figure, the first stop device 30 can be held in a stop preparation state by means of a fixing device 50, wherein the fixing device 50 fixes the first stop device 30 in terms of its position and orientation to prevent it from moving relative to the first adjustment portion 10. In the stop preparation state, one or both of the stop states (i) and (ii) can occur in the respective adjustment states of the spindle-spindle nut mechanism (2) according to the embodiments of the stop devices 30 and 40.

[0111] In the illustrated embodiment, the fixing device 50 is configured on the proximal end section 31. Alternatively, the fixing device 50 may be configured on the distal end section 32 or on the connector 33.

[0112] In linear regulator 1 Figure 4 and Figure 5 as well as Figure 9 and Figure 10 In the illustrated embodiment, the first stop device 30 is held in a stop-ready state by means of a fixing device 50, wherein the fixing device 50 fixes the first stop device 30 in its position and orientation to prevent movement relative to the first adjustment portion 10. Here, the first stop device 30 is fastened and fixed by means of a connecting element 51 in the stop-ready state and thus locked onto the first base 11, and in particular the bottom 15 of the first base. This fastening or locking is achieved by means of two connecting elements 51, 52, each of which extends laterally through a through-hole formed in the proximal end section 31 into a hole formed in the bottom 15 of the first base. The longitudinal direction of the connecting elements 51, 52 may extend along the longitudinal axis L3 of the main shaft or transversely to the longitudinal axis L3 of the main shaft. Alternatively, the linear adjuster 1 may also be implemented such that the linear adjuster 1 has only one connecting element and only one through-hole formed in the proximal end section 31 and the hole in the bottom 15 of the first base.

[0113] By loosening the fixing device 50, and in particular at least one connecting element 51, 52, the first stop device 30 is brought into a stop-release state relative to the first base 11, especially when the abutting surfaces facing each other are respectively inclined and extend as sliding surfaces in pairs. In particular, when the distal abutting surface 36a and the second abutting surface 45b extend along each other and in this case extend at an angle of, for example, greater than 1 degree relative to the radial direction and are radially outward toward the first end E1, the adjustment state (i) does not occur in the stop-release state because the distal abutting surface 36a and the second abutting surface 45b slide past each other in the case of the maximum stop adjuster length Lmax. Here, the first stop device 30 moves radially outward and no longer prevents the second stop device 40 from continuing to move. Similarly, especially when the proximal abutment surface 35a and the first abutment surface 45a extend along each other and, in this case, each extends at an angle greater than 1 degree relative to the radial direction and is radially outward toward the second end E2, the situation that occurs is that the adjustment state (ii) does not occur in the stop release state because, in the case of the maximum stop adjuster length Lmin, the proximal abutment surface 35a and the first abutment surface 45a slide past each other. Here, the first stop device 30 moves radially outward and no longer prevents the second stop device 40 from continuing to move.

[0114] Even without this special design of a surface, these effects can also be achieved by forming the corresponding through holes in the proximal end section 31 and the corresponding holes in the bottom 15 of the first substrate as elongated holes.

[0115] Furthermore, the fixing device 50 can be implemented as a clip connector. As an alternative or addition to the aforementioned variant of the fixing device 50, the fixing device 50 can be implemented as a clamping device, which can be implemented as a press fit between the first base 11 and the first stop device 30, especially the proximal end section 31.

[0116] Therefore, through the design of the stop device 30 and the first base 11, it is possible to achieve that after the mechanical fixation of the fixing device (50) is released, the linear regulator (1) is in the stop release state.

[0117] In the illustrated embodiment of the linear adjuster 1, the first stop device 30 can also be removed radially outward relative to the spindle axis by removing at least one connecting element 51, 52 from its connection with the first base 11 and, in particular, from the hole in the first base 11 when the fixing device 50 is released, thereby placing the fixing device 50 in a stop-released state.

[0118] In each embodiment of the linear adjuster 1, the linear adjuster 1, and especially the spindle-spindle nut mechanism 2, can be designed such that the range of motion of the spindle 3 and spindle nut 5 in the stop-release state is greater than the range of motion of the spindle 3 and spindle nut 5 in the stop-ready state. For this reason, the adjusting parts can move relative to each other from one of the stop-moving positions in the stop-release state using the spindle-spindle nut mechanism during the infeed and outfeed movements.

[0119] Alternatively or additionally, each embodiment of the linear adjuster 1 according to the invention may be implemented such that the second stop device 40 is coupled to or fastened to the second base 21 by means of a fixing device in order to hold the fixing device in a stop-ready state. Here, the fixing device in the stop-ready state fixes the second stop device 40 in terms of its position and orientation to prevent movement relative to the second adjustment portion 20. In the stop-ready state, one or both of the stop states (i) and (ii) may occur in the respective adjustment states of the spindle-spindle nut mechanism 2, depending on the embodiment of the stop devices 30 and 40. The fixing device may be implemented as a variant of the fixing device 50 described herein, acting between the first base 11 and the first stop device 30.

[0120] Alternatively, each embodiment of the linear regulator 1 according to the invention may be implemented such that the transition from the stop preparation state to the stop release state, by at least partially moving the first stop device 30 or the second stop device 40 radially outward relative to the main shaft axis, is achieved by pivoting the first stop device 30 and the second stop device 40. In these embodiments, the fixing device 50 may be implemented as a hinge joint with the connecting element 51 as the axis of rotation, such that after the connecting element 51 and its mating member are released, the connecting element 51 remains in the through hole of the first base 11 and the fixing device 50, and in this state, the fixing device 50 may pivot relative to the first base 11 to the stop release state, in which the first stop device 30 and the second stop device 40 cannot stop each other.

[0121] In an embodiment of the linear regulator 1 having two first stop devices 30, 60, namely stop device 30 and an additional stop device 60, the additional stop device 60 has the combination of features described above based on the stop device 30.

[0122] Therefore, a method for repairing the linear regulator can be performed using one embodiment of the linear regulator 1 described herein. In operation, in a stop-ready state, the first stop device 30 is fixed to the first base 11 by means of the fixing device 50, or the second stop device 40 is fixed to the second base 21 by means of the fixing device. In this stop-ready state, a stop occurs during the insertion or removal movement. From this, according to the method, the corresponding fixing device is released, and the first stop device 30 is moved relative to the first base 11 or the second stop device 40 is moved relative to the second base 21 by means of a moving component opposite to the stop adjustment movement, thereby placing the linear regulator 1 in a stop-released state. Then, the adjusting parts 10 and 20 are moved relative to each other from the stop-movement position by means of the spindle-spindle nut mechanism 2 during the insertion and removal movements.
