Description

Technical Field

[0001] The present application relates to the technical field of precision motion stages, and in particular to an adjustment component. Background Art

[0002] In mechanical design, it is usually necessary to adjust the position of an object, so a corresponding adjustment mechanism needs to be added. According to the degree of freedom of the object being adjusted, some are single-degree-of-freedom and some are multi-degree-of-freedom. At present, the single-degree-of-freedom adjustment mechanisms need to be stacked to achieve multi-degree-of-freedom adjustment of the object. Taking into account the external dimensions of the single-axis adjustment structure itself and the space required for stacking each other, the adjustment component requires a relatively large space size to facilitate the placement of the mechanism. However, when the available space is limited, there will be a problem of insufficient space and the inability to effectively place the mechanism components that occupy a large space. How to place the required multi-degree-of-freedom adjustment components within a narrow space has become a problem that needs to be solved urgently. Summary of the Invention

[0003] The present application provides an adjustment component, which avoids the increase in the stacking size of parts in the thickness direction by partially accommodating the movable slider in the accommodating cavity of the base and arranging the sliding mechanism and part of the movable slider in the same vertical plane, so that the required multi-degree-of-freedom adjustment component can be placed in a narrow space.

[0004] 14. The repairing kit for automotive dents, according to claim 13, wherein the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut.

[0005] The present application provides a first sliding mechanism and a second sliding mechanism in the adjustment component. The first sliding mechanism connects the base and the second slider, and the base and the second slider generate relative displacement in the second direction through the first sliding mechanism. The second sliding mechanism connects the first slider and the second slider, and the first slider and the second slider generate relative displacement in the third direction through the second sliding mechanism, so that the adjustment component has multiple degrees of freedom to adjust the object along the second direction and the third direction. At the same time, by providing a first accommodating cavity on the base, and accommodating part of the first slider in the first accommodating cavity, and the projection of the second sliding mechanism and the first slider along the second direction partially overlap, the first slider and the second sliding mechanism are arranged more compactly along the first direction, which can avoid the increase in the size of the parts stacked in the first direction, i.e., the thickness direction, of the adjustment component, so that the multi-degree-of-freedom adjustment component can be placed in a narrow space.

[0006] In one possible implementation, the first slider includes a main body and an extension portion, the extension portion protruding relative to the main body toward a side closer to the base to be accommodated within the first accommodating cavity, a side wall of the extension portion facing away from the base and a side wall of the main body facing away from the base forming a step structure, and the second sliding mechanism is connected to the wall of the step structure. By forming the step structure in the first slider and connecting the second sliding mechanism to the wall of the step structure, the first slider and the second sliding mechanism are arranged more compactly along the first direction. The second sliding mechanism and the main body of the first slider are located in a plane formed by the second and third directions, which can avoid increasing the size of the components of the adjustment assembly in the first direction, i.e., the thickness direction, thereby allowing the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

[0007] In one possible implementation, there are two extensions located on opposite sides of the body along the second direction, there are at least two second sliding mechanisms, and the step structure formed by each extension is connected to at least one second sliding mechanism. This allows the multiple second sliding mechanisms to provide the adjustment assembly with the ability to freely adjust the degree of freedom along the third direction while remaining aligned with the body of the first slider in the plane defined by the second and third directions. This avoids the need for increased component size stacking in the first direction, i.e., the thickness direction, of the adjustment assembly, allowing for the placement of multi-degree-of-freedom adjustment assemblies within confined spaces.

[0008] In one possible implementation, the base is provided with a groove, the opening of the groove facing the first slider, and the groove cavity of the groove serves as the first accommodating cavity; and / or the base is provided with a channel, the channel extending through the base along the first direction, and the inner cavity of the channel serves as the first accommodating cavity. By providing the base with a groove, a channel, or both, a portion of the first slider is accommodated within the first accommodating cavity, making the arrangement of the first slider and the base more compact along the first direction, thereby avoiding an increase in the size of the components of the adjustment assembly in the first direction, i.e., the thickness direction, and allowing the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

[0009] In one possible implementation, the adjustment assembly further includes a first elastic member connecting the first slider and the second slider, and imparting an elastic restoring force to the first slider and the second slider along the third direction. This allows the adjustment assembly to quickly return to its pre-adjustment state after adjusting the position of the object along the third direction, facilitating further position adjustment.

[0010] In one possible implementation, at least one of the first and second sliders is provided with a second accommodating cavity, with at least a portion of the first elastic member being accommodated within the second accommodating cavity. By accommodating at least a portion of the first elastic member within the second accommodating cavity, the first elastic member and the first and / or second sliders are arranged more compactly along the first direction, thereby preventing an increase in the size of the adjustment assembly's components in the first direction, i.e., the thickness direction, and allowing the multi-degree-of-freedom adjustment assembly to be placed within a narrow space.

[0011] In one possible implementation, there are at least two first sliding mechanisms, located on opposite sides of the first slider along the third direction. By locating multiple first sliding mechanisms on opposite sides of the first slider along the third direction, the multiple first sliding mechanisms and the first slider are arranged more compactly along the first direction, thereby preventing an increase in the size of components of the adjustment assembly in the first direction, i.e., the thickness direction, and allowing the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

[0012] In one possible implementation, the adjustment assembly further includes a second elastic member connecting the base and the second slider, and imparting an elastic restoring force to the base and the second slider along the second direction. This allows the adjustment assembly to quickly return to its pre-adjustment state after adjusting the position of the object along the second direction, facilitating further position adjustment.

[0013] In one possible implementation, the second elastic member is located on one side of the first sliding mechanism in the third direction. This allows the second elastic member and the first sliding mechanism to be located in a plane defined by the second and third directions. This allows the second elastic member and the first sliding mechanism to be arranged more compactly along the first direction, thus preventing increased component size stacking in the first direction, i.e., the thickness direction, of the adjustment assembly. This allows the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

[0014] In one possible implementation, the adjustment assembly includes a first adjustment mechanism configured to drive the base and the second slider to move relative to each other along the second direction, which facilitates the adjustment assembly to adjust the position of the object to be adjusted along the second direction.

[0015] In one possible implementation, the adjustment assembly includes a first limiting mechanism that connects the base and the second slider to limit the relative displacement of the base and the second slider. Providing the first limiting mechanism in the adjustment assembly facilitates precise position adjustment of the object along the second direction in a confined space.

[0016] In one possible implementation, the adjustment assembly includes a second adjustment mechanism configured to drive the first and second sliders to move relative to each other along the third direction. This facilitates the adjustment assembly to adjust the position of the object being adjusted along the third direction.

[0017] In one possible implementation, the adjustment assembly includes a second limiting mechanism that connects the first and second sliders to limit the relative displacement of the first and second sliders. Providing a second limiting mechanism in the adjustment assembly facilitates precise position adjustment of the object along the third direction in confined spaces.

[0018] In one possible implementation, the angle adjustment device includes a locking bolt and a jacking bolt, wherein one of the connecting frame and the base is provided with a first through hole and the other is provided with a first threaded hole, the locking bolt passes through the first through hole and cooperates with the first threaded hole; the connecting frame is provided with a second threaded hole, the jacking bolt includes a first jacking bolt, the first jacking bolt cooperates with the second threaded hole, and one end of the first jacking bolt abuts the base; and / or the base is provided with a third threaded hole, the jacking bolt includes a second jacking bolt, the second jacking bolt cooperates with the third threaded hole, and one end of the second jacking bolt abuts the connecting frame; the number of the jacking bolts is at least three and arranged in an annular pattern, and / or the number of the locking bolts is at least three and arranged in an annular pattern. After the base is lifted relative to the connecting frame by adjusting the jacking bolts, adjusting the locking bolts can cause the mating structure of the base, the first slider, and the second slider to deviate from a plane formed by the second direction and the third direction, thereby achieving swing relative to the second direction and the third direction. When the jacking bolt and the locking bolt are adjusted simultaneously in the first direction, the matching structure of the base, the first slider, and the second slider can be displaced in the first direction. Combined with the displacement in the second and third directions achieved by the first and second sliding mechanisms, the adjustment assembly can ultimately achieve five degrees of freedom position adjustment capabilities.

[0019] In one possible implementation, the second slider is provided with a second through-hole for passing an assembly part through the second slider and the first slider. By passing the assembly part 2 through the first and second sliders, when the second slider and the base are relatively displaced in the second direction via the first sliding mechanism, and the first slider and the second slider are relatively displaced in the third direction via the second sliding mechanism, and the mating structure of the base, the first slider, and the second slider are displaced in the first direction and swung relative to the second and third directions, the assembly can also be adjusted in the five degrees of freedom described above, ultimately achieving multi-degree-of-freedom adjustment of the assembly within a narrow space through the adjustment component.

DETAILED DESCRIPTION

[0044] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0045] For ease of understanding, the English abbreviations and related technical terms involved in the embodiments of this application are explained and described below.

[0046] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0048] It should be understood that the term "and / or" as used herein is simply a term used to describe the existence of three possible relationships between related objects. For example, "A and / or B" can represent the existence of A alone, the existence of both A and B, and the existence of B alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0049] It should be understood that the terms “first”, “second”, etc. used in this application are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0050] In the description of this application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting this application.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0052] In mechanical design, the following requirements are often encountered: adjusting the position of an object. In this case, it is necessary to add a corresponding adjustment mechanism. According to the degree of freedom of the object being adjusted, some are single-degree-of-freedom and some are multi-degree-of-freedom. At present, there are various single-degree-of-freedom motion platforms on the market. For multi-degree-of-freedom, the single-degree-of-freedom motion platforms need to be stacked to achieve multi-degree-of-freedom adjustment. For example, when the position of the first structural member is determined, in a compact and narrow space, when the position of the second structural member relative to the first structural member in the five degrees of freedom directions needs to be accurately manually adjusted, a five-axis manual adjustment mechanism needs to be arranged to fix and adjust the position of the second structural member to obtain the optimal position relative to the first structural member.

[0053] Existing adjustment solutions, considering the dimensions of the single-axis motion platforms themselves and the space required for stacking, require a relatively large space to accommodate the mechanisms. However, when available space is limited, this inevitably leads to insufficient space for the space-consuming components. Therefore, arranging the required five-axis adjustment mechanism within this confined space becomes a pressing issue.

[0054] Figure 1 Schematic diagram of the matching structure of the assembly body 1, the adjustment component 10 and the assembly part 2 provided in the embodiment of the present application. Figure 2 This application provides Figure 1 The exploded view of the matching structure of the assembly body 1, the adjustment component 10 and the assembly part 2, Figure 3 is a schematic structural diagram of the adjustment component 10 provided in an embodiment of the present application, Figure 4 This application provides Figure 3 Exploded view of the middle adjustment assembly 10, combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present application provides an adjustment assembly 10, comprising a connecting frame 100, a base 200, a first slider 300, and a second slider 400, which are sequentially arranged along a first direction (see the X-axis direction in the figure). The adjustment assembly 10 also includes an angle adjustment device 500, which is connected to the connecting frame 100 and the base 200 and is used to adjust the angle of the base 200 relative to the connecting frame 100 in the first direction. Figure 20 Schematic diagram of the matching structure of the connecting frame 100 and the base 200 provided in an embodiment of the present application. Figure 21 This is a schematic diagram of another matching structure of the connecting frame 100 and the base 200 provided in an embodiment of the present application, see Figure 20 and Figure 21In the unadjusted state, the planes on which the connecting frame 100 and the base 200 are located can be perpendicular to the first direction. When the base 200 is adjusted by the angle adjustment device 500, the angle between the plane on which the base 200 is located and the first direction is no longer 90°, that is, the base 200 is deflected in the first direction relative to the connecting frame 100. The adjustment assembly 10 also includes a first sliding mechanism 600 and a second sliding mechanism 700. The first sliding mechanism 600 is connected to the base 200 and the second slider 400. The base 200 and the second slider 400 produce relative displacement in a second direction (see the Y-axis direction in the figure for details) along the extension direction of the first sliding mechanism 600. The second sliding mechanism 700 is connected to the first slider 300 and the second slider 400. The first slider 300 and the second slider 400 produce relative displacement in a third direction (see the Z-axis direction in the figure for details) along the extension direction of the second sliding mechanism 700. Any two directions of the first direction, the second direction and the third direction are perpendicular to each other. A first accommodating cavity 210 is provided on the base 200. Part of the first slider 300 is accommodated in the first accommodating cavity 210. The projections of the second sliding mechanism 700 and the first slider 300 along the second direction partially overlap.

[0055] Combine Figure 3 and Figure 4As shown, the present application provides a first sliding mechanism 600 and a second sliding mechanism 700 in the adjustment assembly 10. The first sliding mechanism 600 connects the base 200 and the second slider 400, and the base 200 and the second slider 400 produce relative displacement in the second direction along the extension direction of the first sliding mechanism 600. The second sliding mechanism 700 connects the first slider 300 and the second slider 400, and the first slider 300 and the second slider 400 produce relative displacement in the third direction along the extension direction of the second sliding mechanism 700. This enables the adjustment assembly 10 to adjust an object with multiple degrees of freedom along the second and third directions. Since the second sliding mechanism 700 needs to be provided between the first slider 300 and the second slider 400, if the first slider 300, the second sliding mechanism 700, and the second slider 400 are simply stacked in sequence, the size of the adjustment assembly 10 along the first direction will increase. By setting a first accommodating cavity 210 on the base 200, part of the first slider 300 is accommodated in the first accommodating cavity 210, so that there is a space between the part of the first slider 300 and the second slider 400, and the second sliding mechanism 700 can be set in the said space. At this time, the projection parts of the second sliding mechanism 700 and the first slider 300 along the second direction overlap. Compared with the part of the first slider 300 that is not accommodated in the first accommodating cavity 210, the protruding part of the second sliding mechanism 700 along the first direction is reduced, so that the first slider 300, the second sliding mechanism 700 and the second slider 400 are arranged more compactly along the first direction, which can avoid the increase in the size of the adjustment assembly 10 due to the stacking of parts in the first direction, that is, the thickness direction, so that the multi-degree-of-freedom adjustment assembly 10 can be placed in a narrow space.

[0056] In one embodiment, combining Figure 1 and Figure 4 As shown, the connecting frame 100 includes a connecting frame body 110 and a connecting plate 120. The base 200, the first slider 300, the second slider 400, and other components within the adjustment assembly 10 form a whole and are fixed to the connecting frame body 110 via bolts. The assembly 2 is mounted on the second slider 400, the assembly body 1 is fixed to the connecting frame 100, and the connecting frame 100 can be fixed to an external structural member via the connecting plate 120.

[0057] In one embodiment, combining Figure 1 and Figure 4 As shown, the assembly body 1 can be fixed independently to an external structural member instead of being fixed to the connecting frame 100. After the connecting frame 100, base 200, first slider 300, second slider, other components within the adjustment assembly 10, and assembly member 2 are connected, the assembly body 1 is fixed to the external structural member as a whole via the connecting plate 120 of the connecting frame 100.

[0058] In one embodiment, Figure 7Schematic diagram of the cooperation structure of the base 200 and the first slider 300 provided in an embodiment of the present application. Figure 8 This application provides Figure 7 The exploded view of the matching structure of the middle base 200 and the first slider 300, combined with Figure 4 、 Figure 7 and Figure 8 As shown, the first slider 300 includes a main body 310 and an extension portion 320. The extension portion 320 protrudes relative to the main body 310 toward the side close to the base 200 to be accommodated in the first accommodating cavity 210. The side wall of the extension portion 320 facing away from the base 200 and the side wall of the main body 310 facing away from the base 200 form a step structure 321, and the second sliding mechanism 700 is connected to the wall of the step structure 321. By forming a step structure 321 in the first slider 300 and connecting the second sliding mechanism 700 to the wall of the step structure 321, the second sliding mechanism 700 can be accommodated on the step structure 321, and the projections of the second sliding mechanism 700 and the main body 310 along the second direction can at least partially overlap, that is, the second sliding mechanism 700 does not have a portion protruding along the first direction relative to the main body 310, and the second sliding mechanism 700 and the main body 310 of the first slider 300 are in the first plane 311, and the first plane 311 is parallel to the plane formed by the second direction and the third direction, so that the first slider 300 and the second sliding mechanism 700 are arranged more compactly along the first direction.

[0059] In one embodiment, see Figure 4 、 Figure 7 and Figure 8 There are two extensions 320 located on opposite sides of the body 310 along the second direction. There are at least two second sliding mechanisms 700, and the step structure 321 formed by each extension 320 is connected to at least one second sliding mechanism 700. By providing at least one second sliding mechanism 700 on opposite sides of the first slider 300 along the second direction, when conditions for relative displacement between the first slider 300 and the second slider 400 are met, the at least one second sliding mechanism 700 located on opposite sides of the first slider 300 along the second direction can serve as a carrier for the relative displacement between the first slider 300 and the second slider 400. This can balance the force distribution between the first slider 300 and the second slider 400 during relative displacement, facilitating relative displacement of the first slider 300 and the second slider 400 in the third direction along the extension direction of the second sliding mechanism 700.

[0060] In one embodiment, Figure 5 This is a schematic diagram of the structure of the base 200 provided in the embodiment of the present application, combined with Figure 4 and Figure 5As shown, the base 200 is provided with a groove 220, the opening of the groove 220 facing the first slider 300. The groove cavity of the groove 220 serves as the first accommodating cavity 210. The extension portion 320 of the first slider 300 can be accommodated in the groove cavity. By forming the groove 220 in the structure of the base 200 itself, the extension portion 320 of the first slider 300 can be accommodated in the groove cavity (first accommodating cavity 210) of the groove 220 without increasing the size of the base 200 along the first direction, making the first slider 300 and the base 200 more compactly arranged along the first direction.

[0061] In one embodiment, Figure 6 This is a schematic diagram of the structure of the base 200 provided in the embodiment of the present application, combined with Figure 6 、 Figure 7 and Figure 8 As shown, the base 200 is provided with a channel 230 that extends through the base 200 along a first direction. The inner cavity of the channel 230 serves as the first accommodating cavity 210. The extension portion 320 of the first slider 300 can be accommodated within the inner cavity of the channel 230. By forming the channel 230 within the structure of the base 200 itself, the extension portion 320 of the first slider 300 can be accommodated within the first accommodating cavity 210 of the channel 230 without increasing the size of the base 200 along the first direction, thereby making the first slider 300 and the base 200 more compactly arranged along the first direction.

[0062] In one embodiment, combining Figure 4 and Figure 6 As shown, the base 200 is provided with a groove 220 and a channel 230. The opening of the groove 220 faces the first slider 300. The groove 220 forms a portion of the first accommodating cavity 210. The channel 230 can penetrate the base 200 in the first direction, and the inner cavity of the channel 230 also forms a portion of the first accommodating cavity 210. In this case, the channel 230 can penetrate the bottom wall of the groove 220 in the first direction, and the inner cavity of the channel 230 can form a portion of the groove 220. By forming the groove 220 in the structure of the base 200 itself and the channel 230 penetrating the bottom wall of the base 200 in the first direction, the extension 320 of the first slider 300 can be accommodated within the first accommodating cavity 210 shared by the groove 220 and the channel 230 without increasing the size of the base 200 in the first direction, thereby making the first slider 300 and the base 200 more compactly arranged in the first direction.

[0063] In one embodiment, Figure 9 This is an exploded view of the matching structure of the base 200, the first slider 300 and the second slider 400 provided in the embodiment of the present application. Figure 9The adjustment assembly further includes a first bolt 420, a second bolt 440, a third bolt 610, and a fourth bolt 710.

At least one first fixing hole 430 is located on the second slider 400 at a position corresponding to the second sliding mechanism 700 along the first direction, and the first bolt 420 is threadedly connected to the first fixing hole 430 and passes through the through hole on the third sliding body 7001 to achieve the connection between the second slider 400 and the first sliding mechanism 700; a third fixing hole 720 is provided on the fourth sliding body 7002 of the second sliding mechanism 700, and the third fixing hole 720 is located at a position corresponding to the fourth sliding body 7002 and the first slider 300 along the first direction, and the fourth bolt 710 passes through the through hole on the first slider 300 and is threadedly connected to the third fixing hole 720 to achieve the connection between the first slider 300 and the second sliding mechanism 700; when the first slider 300 and the second slider 400 generate relative displacement in the third direction along the extension direction of the second sliding mechanism 700, the third sliding body 7001 and the fourth sliding body 7002 slide relative to each other through the slide rail (not shown in the figure) in the second sliding mechanism 700, so as to limit the displacement direction of the first slider 300 and the second slider 400 to the third direction. In one embodiment, see Figure 9The two first sliding mechanisms 600 are located on opposite sides of the body 310 of the first slider 300 along the third direction. Each first sliding body 6001 is provided with at least four second fixing holes 620.

[0064] In one embodiment, Figure 10 Schematic diagram of the matching structure of the base 200, the first slider 300 and the second slider 400 provided in an embodiment of the present application. Figure 11 This application provides Figure 10 The exploded view of the matching structure of the middle base 200, the first slider 300 and the second slider 400, combined with Figure 10 and Figure 11 As shown, the adjustment assembly also includes a first elastic member 800, which connects the first slider 300 and the second slider 400. The first elastic member 800 provides elastic restoring force to the first and second sliders 300 and 400 along the third direction. This allows the adjustment assembly to quickly return to its pre-adjustment state after adjusting the position of the object along the third direction, facilitating further position adjustment. The first elastic member 800 also serves to eliminate the sliding gap between the first and second sliders 300 and 400 along the third direction.

[0065] In one embodiment, combining Figure 10 and Figure 11As shown, at least one of the first slider 300 and the second slider 400 is provided with a second accommodating cavity 410 , and at least a portion of the first elastic member 800 is accommodated in the second accommodating cavity 410 . Taking the second slider 400 as an example, the first elastic member 800 can be a spring, which extends along the third direction; the first slider 300 includes a first connecting column 330, and the second slider 400 includes a second connecting column 450. The first connecting column 330 extends into the second accommodating cavity 410, and one end of the spring located in the second accommodating cavity 410 is connected to the first connecting column 330, and the other end of the spring is connected to the second connecting column 450; by extending the spring along the third direction, when the first slider 300 and the second slider 400 generate relative displacement in the third direction along the second sliding mechanism 700, the first slider 300 and the second slider 400 will not be affected by the force of the spring biased in the first direction and the second direction, thereby reducing the friction between the first slider 300 and the second slider 400, making the sliding of the first slider 300 and the second slider 400 smoother, and avoiding assembly offset between the first slider 300 and the second slider 400. When at least a portion of the first elastic member 800 is accommodated within the second accommodating cavity 410 of the first slider 300, the first elastic member 800 and the first slider 300 can be arranged more compactly along the first direction. When at least a portion of the first elastic member 800 is accommodated within the second accommodating cavity 410 of the second slider 400, the first elastic member 800 and the second slider 400 can be arranged more compactly along the first direction. This prevents the increase in the size of the adjustment assembly due to stacking of parts in the thickness direction, allowing the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

[0066] In one embodiment, see Figure 11 There are at least two first sliding mechanisms 600, with the at least two first sliding mechanisms 600 located on opposite sides of the first slider 300 along the third direction. In one embodiment, the projections of the multiple first sliding mechanisms 600 and the first slider 300 along the third direction can completely overlap, such that the multiple first sliding mechanisms 600 do not have any portion protruding relative to the first slider 300 along the first direction. By locating the multiple first sliding mechanisms 600 on opposite sides of the first slider 300 along the third direction, the multiple first sliding mechanisms 600 and the first slider 300 are arranged more compactly along the first direction, thereby avoiding an increase in the size of the adjustment assembly components in the first direction, i.e., the thickness direction, and allowing the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

[0067] In one embodiment, see Figure 11The adjustment assembly further includes a second elastic member 900, which connects the base 200 and the second slider 400. The second elastic member 900 provides an elastic restoring force along the second direction to the base 200 and the second slider 400. This allows the adjustment assembly to quickly return to its pre-adjustment state after adjusting the position of the object along the second direction, facilitating further position adjustment.

[0068] In one embodiment, see Figure 11 , the second elastic member 900 is located on one side of the third direction of the first sliding mechanism 600. Schematically, the second elastic member 900 can be located between the first sliding mechanism 600 and the first slider 300. The base 200 also includes a third connecting column 240. One end of the second elastic member 900 can be connected to the third connecting column 240, and the other end of the second elastic member 900 can be connected to the fourth connecting column (not shown) of the second slider 400. By extending the second elastic member 900 along the third direction, when the base 200 and the second slider 400 generate relative displacement in the second direction along the first sliding mechanism 600, the base 200 and the second slider 400 will not be affected by the force of the second elastic member 900 biased toward the first direction and the third direction, thereby reducing the friction between the base 200 and the second slider 400, making the sliding of the base 200 and the second slider 400 smoother, and avoiding assembly offset between the first slider 300 and the second slider 400. Combined Figure 7 and Figure 11 As shown, the projections of the first sliding mechanism 600, the second elastic member 900 and the main body 310 of the first slider 300 along the third direction can completely overlap, that is, the main body 310, the first sliding mechanism 600 and the second elastic member 900 are located in the plane formed by the second direction and the third direction, so that the first slider 300, the first sliding mechanism 600 and the second elastic member 900 can be arranged more compactly along the first direction, which can avoid the increase in the size of parts stacked in the first direction, i.e., the thickness direction, of the adjustment component, so that the multi-degree-of-freedom adjustment component can be placed in a narrow space.

[0069] In one embodiment, Figure 12 Schematic diagram of the matching structure of the base 200, the first slider 300 and the second slider 400 provided in an embodiment of the present application. Figure 13 This application provides Figure 12 A top view of the matching structure of the middle base 200, the first slider 300 and the second slider 400, Figure 14 This application provides Figure 12 The side view of the matching structure of the middle base 200, the first slider 300 and the second slider 400, combined with Figure 12 、 Figure 13 and Figure 14As shown, the adjustment assembly further includes a first adjustment mechanism 600a, which is used to drive relative movement between the base 200 and the second slider 400 in the second direction. Illustratively, the first adjustment mechanism 600a can be a micrometer component. The fixed base of the first adjustment mechanism 600a can be connected to the base 200 and the second slider 400. By turning the knob of the first adjustment mechanism 600a, the screw of the first adjustment mechanism 600a can push the movable base connected to the base 200 in the second direction, thereby driving the base 200 relative to the second slider 400 in the second direction. This facilitates the adjustment assembly to adjust the position of the object being adjusted in the second direction. The first adjustment mechanism 600a does not have a portion protruding in the first direction relative to the base 200 and the second slider 400. That is, the projections of the first adjustment mechanism 600a, the base 200, and the second slider 400 in the first direction completely overlap. This avoids the increase in component size of the adjustment assembly in the first direction, i.e., the thickness direction, and enables the placement of a multi-degree-of-freedom adjustment assembly in a confined space.

[0070] In one embodiment, Figure 15 This is a schematic diagram of the matching structure of the base 200, the first slider 300 and the second slider 400 provided in the embodiment of the present application, see Figure 15 The adjustment assembly also includes a first limiting mechanism 20, which connects the base 200 and the second slider 400 to limit the relative displacement distance between the base 200 and the second slider 400. Schematically, the first limiting mechanism 20 includes a movable plate connected to the second slider 400. The movable plate has a limiting hole. When the first adjustment mechanism 600a drives the second slider 400 to move in the second direction relative to the base 200, the movable plate moves in the second direction until the limiting hole abuts against a limiting member located on the base 200 and passing through the limiting hole. At this point, the second slider 400 cannot move in the second direction relative to the base 200. When the second slider 400 needs to be restored relative to the base 200, the knob of the first adjustment mechanism 600a can be rotated to move the second slider 400 in a direction opposite to the second direction. Under the elastic restoring force exerted by the second elastic member 900 on the base 200 and the second slider 400 in the second direction, the second slider 400 can be accurately restored to its original position. The provision of a first limiting mechanism 20 within the adjustment assembly facilitates precise position adjustment of the object being adjusted along the second direction in confined spaces. The first limiting mechanism 20 has no portion protruding along the first direction relative to the base 200 and the second slider 400. That is, the projections of the first limiting mechanism 20, the base 200, and the second slider 400 along the first direction completely overlap. This prevents increased component size stacking in the first direction, i.e., the thickness direction, of the adjustment assembly, allowing the multi-degree-of-freedom adjustment assembly to be placed within confined spaces.

[0071] In one embodiment, combining Figure 12 、 Figure 13 and Figure 14 As shown, the adjustment assembly includes a second adjustment mechanism 700a, which is used to drive the first and second sliders 300, 400 to move relative to each other in a third direction. Illustratively, the second adjustment mechanism 700a can be a micrometer component. The fixed base of the second adjustment mechanism 700a can be connected to the first and second sliders 300, 400. By turning the knob of the second adjustment mechanism 700a, the screw of the second adjustment mechanism 700a can push the movable base connected to the second slider 400 in the third direction, thereby driving the second slider 400 to move relative to the first slider 300 in the third direction. This facilitates the adjustment assembly to adjust the position of the object being adjusted in the third direction. The second adjustment mechanism 700a does not have a portion protruding in the first direction relative to the first and second sliders 300, 400. That is, the projections of the second adjustment mechanism 700a and the first and second sliders 300, 400 in the first direction completely overlap. This avoids the increase in component size of the adjustment assembly in the first direction, i.e., the thickness direction, and allows the multi-degree-of-freedom adjustment assembly to be placed in a confined space.

[0072] In one embodiment, Figure 16 This application provides Figure 15 A schematic diagram of the cooperation structure of the middle base 200, the first slider 300 and the second slider 400 from another perspective, see Figure 16The adjustment assembly includes a second limiting mechanism 30, which connects the first slider 300 and the second slider 400 to limit the relative displacement distance between the first slider 300 and the second slider 400. Illustratively, the second limiting mechanism 30 includes a movable plate connected to the second slider 400. The movable plate has a limiting hole. When the second adjustment mechanism 700a drives the second slider 400 to move relative to the first slider 300 in the third direction, the movable plate moves accordingly in the third direction until the limiting hole abuts against a limiting member located on the first slider 300 and passing through the limiting hole. At this point, the second slider 400 can no longer move relative to the first slider 300 in the third direction. When the second slider 400 needs to be restored relative to the first slider 300, the knob of the second adjustment mechanism 700a can be rotated to move the second slider 400 in the direction opposite to the third direction. Under the action of the elastic restoring force applied by the first elastic member 800 to the first and second sliders 300, 400 can be accurately restored to its original position. By providing the second limiting mechanism 30 in the adjustment assembly, the adjustment assembly can facilitate precise position adjustment of the object being adjusted along the third direction in a narrow space. The second limiting mechanism 30 does not have a portion protruding along the first direction relative to the first and second sliders 300, 400. That is, the projections of the second limiting mechanism 30 and the first and second sliders 300, 400 along the first direction can completely overlap. This can avoid the increase in the size of the components of the adjustment assembly in the first direction, i.e., the thickness direction, and allows the multi-degree-of-freedom adjustment assembly to be placed in a narrow space.

The base 200 is provided with a first through hole 40, and the connecting frame 100 is provided with a first threaded hole 50. The locking bolt 510 passes through the first through hole 40 and cooperates with the first threaded hole 50. In one embodiment, the base 200 is provided with a first threaded hole 50, and the connecting frame 100 is provided with a first through hole 40.

Figure 20 and Figure 21 The deflection of the base 200 relative to the connecting frame 100 is shown. Simultaneously adjusting the first jacking bolt 521 and the locking bolt 510 in the first direction causes the mating structure of the base 200, the first slider 300, and the second slider 400 to move in the first direction. Combined with the displacement in the second and third directions achieved by the first sliding mechanism 600 and the second sliding mechanism 700, the adjustment assembly ultimately possesses five degrees of freedom of position adjustment capability.

A third threaded hole 70 is provided on the base 200, the lifting bolt 520 includes a second lifting bolt 522, the second lifting bolt 522 cooperates with the third threaded hole 70, and one end of the second lifting bolt 522 abuts against the base connecting frame 100. Combined Figure 18 、 Figure 20 and Figure 21 As shown, after the base 200 is lifted relative to the connecting frame 100 by adjusting the second lifting bolt 522, the locking bolt 510 can be adjusted to deflect the matching structure of the base 200, the first slider 300 and the second slider 400 relative to the plane formed by the second direction and the third direction, that is, swing relative to the second direction and the third direction is achieved, as shown in FIG. Figure 20 and Figure 21The deflection of the base 200 relative to the connecting frame 100 is shown. Simultaneously adjusting the second jacking bolt 522 and the locking bolt 510 in the first direction causes the coordinated structure of the base 200, the first slider 300, and the second slider 400 to move in the first direction. Combined with the displacement in the second and third directions achieved by the first sliding mechanism 600 and the second sliding mechanism 700, the adjustment assembly ultimately possesses five degrees of freedom of position adjustment capability.

[0075] In one embodiment, Figure 19 This is an exploded view of the matching structure of the base 200, the first slider 300 and the second slider 400 provided in the embodiment of the present application. Figure 19 , the angle adjustment device 500 includes a locking bolt 510 and a lifting bolt 520, a first through hole 40 is provided on the base 200, a first threaded hole 50 is provided on the connecting frame 100, the locking bolt 510 passes through the first through hole 40 and cooperates with the first threaded hole 50; in one embodiment, a first threaded hole 50 is provided on the base 200, the connecting frame 100 is provided with a first through hole 40, the locking bolt 510 passes through the first through hole 40 and cooperates with the first threaded hole 50. A second threaded hole 60 is provided on the connecting frame 100, and a third threaded hole 70 is provided on the base 200. The lifting bolt 520 includes a first lifting bolt 521 and a second lifting bolt 522.

Combined Figure 19 、 Figure 20 and Figure 21 As shown, after the base 200 is lifted relative to the connecting frame 100 by adjusting the first lifting bolt 521 and the second lifting bolt 522, the locking bolt 510 can be adjusted to deflect the matching structure of the base 200, the first slider 300 and the second slider 400 relative to the plane formed by the second direction and the third direction, that is, to achieve swing relative to the second direction and the third direction, as shown in FIG. Figure 20 and Figure 21 The deflection of the base 200 relative to the connecting frame 100 is shown. Simultaneously adjusting the first jacking bolt 521, the second jacking bolt 522, and the locking bolt 510 in the first direction causes the coordinated structure of the base 200, the first slider 300, and the second slider 400 to move in the first direction. Combined with the displacement in the second and third directions achieved by the first sliding mechanism 600 and the second sliding mechanism 700, the adjustment assembly ultimately possesses five degrees of freedom of position adjustment capability.

[0076] In one embodiment, see Figure 19The connecting frame 100 further includes a connecting portion 130, which is used to assemble the base 200 to the connecting frame 100. There are at least three jacking bolts 520, which are arranged in a circular pattern. In an exemplary embodiment, the at least three jacking bolts 520 are arranged in a circular pattern around the connecting portion 130, so that when the base 200 is lifted relative to the connecting frame 100, the jacking bolts 520 can provide a uniformly distributed force to the connecting frame 100 and the base 200. There are at least three locking bolts 510, which are arranged in a circular pattern. In an exemplary embodiment, the at least three locking bolts 510 are arranged in a circular pattern around the connecting portion 130, so that when the mating structure of the base 200, the first slider 300, and the second slider 400 is deflected relative to the connecting frame 100, the locking bolts 510 can provide a uniformly distributed force to the connecting frame 100 and the base 200.

[0077] In one embodiment, Figure 22 This is an exploded view of the matching structure of the first slider 300, the second slider 400 and the assembly part 2 provided in the embodiment of the present application. Figure 22 The second slider 400 is provided with a second through-hole 80 for passing the assembly part 2 through the second through-hole 80, so that the assembly part 2 can pass through the second slider 400 and the first slider 300.

[0078] In summary, the overall solution of this application can be as follows: Figure 1 、 Figure 4 、 Figure 10 、 Figure 14 as well as Figure 16As shown, the assembly body 1 has bolt mounting holes that can fix the assembly body 1 to the connecting frame 100. The base 200 is connected to the second slider 400 via a first sliding mechanism 600. A second elastic member 900 is arranged between the base 200 and the second slider 400 in the second direction to eliminate the sliding gap in this direction; the second slider 400 is connected to the first slider 300 via a second sliding mechanism 700. A first elastic member 800 is arranged between the first slider 300 and the second slider 400 in the third direction to eliminate the sliding gap in this direction; the first slider 300 is hidden between the base 200 and the first movable block and the second slider 400. The two sets of first sliding mechanisms 600 and second sliding mechanisms 700 are arranged in a U-shaped pattern, and the two sets of first elastic members 800 and second elastic members 900 are arranged in a U-shaped pattern, fully utilizing the first direction, i.e., the thickness direction, of the adjustment component to avoid an increase in the size of parts stacked in the thickness direction. The first adjustment mechanism 600a, the second adjustment mechanism 700a, the first limiting mechanism 20, and the second limiting mechanism 30 arranged on the periphery are also arranged in a U-shaped pattern, thereby realizing a two-axis pushing action along the second direction and the third direction: the first adjustment mechanism 600a can push the second slider 400 to move back and forth along the second direction relative to the base 200; the second adjustment mechanism 700a can push the first slider 300 to move back and forth along the third direction relative to the second slider 400. The above constitutes an integral assembly, which is assembled to the connecting frame 100 via locking bolts 510 and lifting bolts 520. When the lifting bolts 520 are lifted, the U-shaped integral assembly can be swung relative to the connecting frame 100 along the second direction and the third direction by adjusting the locking bolts 510 at the four corners. When the positions of the locking bolts 510 and the lifting bolts 520 in the first direction are adjusted simultaneously, the integral assembly can be translated in the first direction. The assembly part 2 is mounted and fixed on the first slider 300 and the second slider 400 , thereby ultimately achieving position adjustment of the assembly part 2 with respect to the assembly body 1 in five degrees of freedom in a narrow space.
