[0002] In mechanical design, it is usually necessary to adjust the position of an object, so it is necessary to add a corresponding adjustment mechanism. According to the direction of the degrees 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. Considering 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

[0005] The present application provides a first sliding mechanism and a second sliding mechanism in the adjustment component, wherein the first sliding mechanism is connected to 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, and the second sliding mechanism is connected to 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 multi-degree-of-freedom adjustment of 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 part of the second sliding mechanism and the first slider along the second direction overlap, the first slider and the second sliding mechanism are arranged more compactly along the first direction, which can avoid the increase in the stacking size of the parts 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.

[0011] In a possible implementation, the number of the first sliding mechanisms is at least two, and the at least two first sliding mechanisms are located on opposite sides of the first slider along the third direction. By locating the plurality of first sliding mechanisms on opposite sides of the first slider along the third direction, the plurality of first sliding mechanisms and the first slider are arranged more compactly along the first direction, which can avoid increasing 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.

[0012] In a possible implementation, the adjustment component further includes a second elastic member, the second elastic member connects the base and the second slider, and the second elastic member provides elastic restoring force to the base and the second slider along the second direction. This enables the adjustment component to quickly restore to the state before adjustment after adjusting the position of the object to be adjusted along the second direction, which is conducive to the next step of position adjustment.

This allows the second elastic member and the first sliding mechanism to be located in a plane formed by the second direction and the third direction, and the second elastic member and the first sliding mechanism are arranged more compactly along the first direction, which can avoid increasing 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.

When the jacking bolt and the locking bolt are adjusted in the first direction at the same time, the matching structure of the base, the first slider and the second slider can be displaced in the first direction.

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 the present application are explained and described below.

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

[0047] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" 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 other meanings.

[0048] It should be understood that the term "and / or" used in this article is only a description of the same field of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0049] It should be understood that the terms “first”, “second”, etc. used in the present application are only used for the purpose of distinguishing the description, 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 the present application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0051] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 to be adjusted, some are single-degree-of-freedom and some are multi-degree-of-freedom. At present, there are various single-degree-of-freedom motion tables on the market. For multi-degree-of-freedom, the single-degree-of-freedom motion tables 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, it is necessary to accurately manually adjust the position of the second structural member relative to the first structural member in the five degrees of freedom directions. A five-axis manual adjustment mechanism needs to be arranged to fix and adjust the position of the second structural member to obtain the best position relative to the first structural member.

[0053] The above existing adjustment schemes, considering the external dimensions of the single-axis motion table itself and the space required for stacking, need to provide a relatively large space size to facilitate the placement of the mechanism. When the available space is limited, there is inevitably a problem of insufficient space and inability to effectively place the mechanism components that occupy a large space. How to place the required five-axis adjustment mechanism in a narrow space range has become an urgent problem to be solved.

[0054] Figure 1 It is a 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 An 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 diagram of the structure of the adjustment component 10 provided in the embodiment of the present application, Figure 4 This application provides Figure 3 An 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 arranged in sequence along a first direction (see the X-axis direction in the figure for details). 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 deflected in the first direction relative to the connecting frame 100; Fig. 20 is a schematic diagram of the matching structure of the connecting frame 100 and the base 200 provided in an embodiment of the present application, Fig.21 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 Fig. 20 and Fig.21In an 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 component 10 also includes a first sliding mechanism 600 and a second sliding mechanism 700. The first sliding mechanism 600 connects the base 200 and the second slider 400. The base 200 and the second slider 400 generate 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 connects the first slider 300 and the second slider 400. The first slider 300 and the second slider 400 generate 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 among 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] Combination Figure 3 and Figure 4As shown, the present application provides a first sliding mechanism 600 and a second sliding mechanism 700 in the adjustment component 10, wherein the first sliding mechanism 600 connects the base 200 and the second slider 400, and the base 200 and the second slider 400 generate relative displacement in the second direction along the extension direction of the first sliding mechanism 600, and 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 generate relative displacement in the third direction along the extension direction of the second sliding mechanism 700, so that the adjustment component 10 has multi-degree-of-freedom adjustment of the object along the second direction and the third direction. 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 component 10 along the first direction will increase. By setting the 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 vacant 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 vacant 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 component 10 due to the stacking of parts in the first direction, i.e., the thickness direction, so that the multi-degree-of-freedom adjustment component 10 can be placed in a narrow space.

[0056] In one embodiment, in combination Figure 1 and Figure 4 As shown, the connecting frame 100 includes a connecting frame body 110 and a connecting plate 120, and the base 200, the first slider 300, the second slider 400 and other components inside the adjustment assembly 10 form a whole and are fixed to the connecting frame body 110 by bolts. The assembly part 2 is installed 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 the external structural member through the connecting plate 120.

[0057] In one embodiment, in combination Figure 1 and Figure 4 As shown, the assembly body 1 may not be fixed on the connecting frame 100, but may be fixed on an external structural member alone. After the connecting frame 100, the base 200, the first slider 300, the second slider, other parts inside the adjustment assembly 10, and the assembly member 2 are connected, they are fixed to the external structural member as a whole through the connecting plate 120 of the connecting frame 100.

[0058] In one embodiment, Figure 7is a schematic diagram of the matching 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 a side close to the base 200 to be accommodated in the first accommodating cavity 210. A side wall of the extension portion 320 facing away from the base 200 and a side wall of the main body 310 facing away from the base 200 form a step structure 321. 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 and 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 has no 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 two 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 respectively arranging at least one second sliding mechanism 700 on two opposite sides of the first slider 300 along the second direction, when the first slider 300 and the second slider 400 are in a condition of generating relative displacement, the at least one second sliding mechanism 700 located on two opposite sides of the first slider 300 along the second direction can serve as a carrier of the relative displacement of the first slider 300 and the second slider 400, and can balance the force distribution of the first slider 300 and the second slider 400 during relative displacement, which is conducive to the 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.

The extension portion 320 of the first slider 300 can be accommodated in the groove cavity. By forming the groove 220 on 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, so that the first slider 300 and the base 200 are arranged more compactly along the first direction.

[0061] In one embodiment, Figure 6 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, a channel 230 is provided on the base 200, and the channel 230 penetrates the base 200 along the first direction, and the inner cavity of the channel 230 is the first accommodating cavity 210. The extension portion 320 of the first slider 300 can be accommodated in the inner cavity of the channel 230.

[0064] In one embodiment, Fig.10 2 is a 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. Fig.11 This application provides Fig.10 The exploded view of the matching structure of the middle base 200, the first slider 300 and the second slider 400, combined with Fig.10 and Fig.11 As shown, the adjustment component also includes a first elastic member 800, which connects the first slider 300 and the second slider 400, and provides elastic restoring force to the first slider 300 and the second slider 400 along the third direction. This allows the adjustment component to quickly return to the state before adjustment after adjusting the position of the object to be adjusted along the third direction, which is conducive to the next step of position adjustment. The first elastic member 800 can also be used to eliminate the sliding gap between the first slider 300 and the second slider 400 along the third direction.

[0065] In one embodiment, in combination Fig.10 and Fig.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 being provided with the second accommodating cavity 410 as an example, schematically, the first elastic member 800 can be a spring, and the spring 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, 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 making the spring extend 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 the assembly offset of the first slider 300 and the second slider 400. When at least part of the first elastic member 800 is accommodated in the second accommodation 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 part of the first elastic member 800 is accommodated in the second accommodation 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 can avoid the increase in the size of the adjustment assembly due to the stacking of parts in the thickness direction, so that the multi-degree-of-freedom adjustment assembly can be placed in a narrow space.

[0066] In one embodiment, see Fig.11 , the number of the first sliding mechanisms 600 is at least two, and at least two first sliding mechanisms 600 are located on opposite sides of the first slider 300 along the third direction. In one embodiment, the projections of the plurality of first sliding mechanisms 600 and the first slider 300 along the third direction can completely overlap, so that the plurality of first sliding mechanisms 600 have no protruding parts along the first direction relative to the first slider 300. By locating the plurality of first sliding mechanisms 600 on opposite sides of the first slider 300 along the third direction, the plurality of first sliding mechanisms 600 and the first slider 300 are arranged more compactly along the first direction, which can avoid the increase in the stacking of the parts size of the adjustment component in the first direction, i.e., the thickness direction, so that the multi-degree-of-freedom adjustment component can be placed in a narrow space.

[0067] In one embodiment, see Fig.11The adjustment component also includes a second elastic member 900, which is connected to the base 200 and the second slider 400, and provides elastic restoring force along the second direction to the base 200 and the second slider 400. This allows the adjustment component to quickly restore to the state before adjustment after adjusting the position of the object to be adjusted along the second direction, which is conducive to the next step of position adjustment.

[0068] In one embodiment, see Fig.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 the assembly offset between the first slider 300 and the second slider 400. Combined with Figure 7 and Fig.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 a 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.

Schematically, the first adjustment mechanism 600a can be a micrometer component. The fixed seat of the first adjustment mechanism 600a can be connected to the base 200 and the second slider 400. By rotating 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 to move toward the second direction, and then drive the base 200 to move relative to the second slider 400 toward the second direction, which is conducive to the adjustment assembly to adjust the position of the object to be adjusted along the second direction. The first adjustment mechanism 600a does not have a protruding part along the first direction relative to the base 200 and the second slider 400, that is, the projection of the first adjustment mechanism 600a and the base 200 and the second slider 400 along the first direction can completely overlap, which can avoid the increase in the size of the parts stacked in the first direction, that is, the thickness direction of the adjustment assembly, so that the multi-degree-of-freedom adjustment assembly can be placed in a narrow space.

Schematically, the first limiting mechanism 20 includes a movable sheet, which is connected to the second slider 400, and the movable sheet 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 sheet moves in the second direction until the limiting hole abuts against the limiting member located on the base 200 and passing through the limiting hole, at which time the second slider 400 can no longer move in the second direction relative to the base 200. When the position of the second slider 400 relative to the base 200 needs to be restored, the knob of the first adjustment mechanism 600a can be rotated to move the second slider 400 in the opposite direction of the second direction. Under the action of the elastic restoring force given by the second elastic member 900 to the base 200 and the second slider 400 along the second direction, the second slider 400 can be accurately restored to the original position. The first limiting mechanism 20 is provided in the adjustment component, which can facilitate the adjustment component to precisely adjust the position of the object to be adjusted along the second direction in a narrow space. The first limiting mechanism 20 has no protruding portion 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 can completely overlap, 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.

[0071] In one embodiment, in combination Fig.12 , Fig.13 and Fig.14 As shown, the adjustment assembly includes a second adjustment mechanism 700a, and the second adjustment mechanism 700a is used to drive the first slider 300 and the second slider 400 to move relative to each other along the third direction. Schematically, the second adjustment mechanism 700a can be a micrometer component. The fixed seat of the second adjustment mechanism 700a can be connected to the first slider 300 and the second slider 400. By rotating 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 to move toward the third direction, and then drive the second slider 400 to move relative to the first slider 300 toward the third direction, which is conducive to the adjustment assembly to adjust the position of the object to be adjusted along the third direction. The second adjustment mechanism 700a does not have a protruding part along the first direction relative to the first slider 300 and the second slider 400, that is, the projection of the second adjustment mechanism 700a and the first slider 300 and the second slider 400 along the first direction can completely overlap, which can avoid the increase in the size of the parts stacked in the first direction, that is, the thickness direction of the adjustment assembly, so that the multi-degree-of-freedom adjustment assembly can be placed in a narrow space.

Schematically, the second limiting mechanism 30 includes a movable sheet, which is connected to the second slider 400, and the movable sheet has a limiting hole. When the second adjustment mechanism 700a drives the second slider 400 to move toward the third direction relative to the first slider 300, the movable sheet moves toward the third direction accordingly until the limiting hole abuts against the limiting member located on the first slider 300 and passing through the limiting hole, at which time the second slider 400 can no longer move toward the third direction relative to the first slider 300. When the second slider 400 needs to be restored relative to the first slider 300, the second slider 400 can be moved in the opposite direction of the third direction by rotating the knob of the second adjustment mechanism 700a. Under the action of the elastic restoring force given to the first slider 300 and the second slider 400 by the first elastic member 800 along the third direction, the second slider 400 can be accurately restored to the original position. By providing the second limiting mechanism 30 in the adjustment component, it can be beneficial for the adjustment component to accurately adjust the position of the object to be adjusted along the third direction in a narrow space. The second limiting mechanism 30 does not have a protruding part along the first direction relative to the first slider 300 and the second slider 400, that is, the projection of the second limiting mechanism 30 and the first slider 300 and the second slider 400 along the first direction can completely overlap, which can avoid the increase in the stacking of the size of the parts of the adjustment component in the first direction, that is, the thickness direction, so that the multi-degree-of-freedom adjustment component can be placed in a narrow space.

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 arrangement, so as to realize the 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 component, which is assembled to the connecting frame 100 through the locking bolts 510 and the lifting bolts 520; when the lifting bolts 520 are lifted, the U-shaped integral component 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 at the same time, the translation of the integral component in the first direction can be realized. The assembly part 2 is mounted and fixed on the first slider 300 and the second slider 400, and finally the position adjustment of the assembly part 2 with respect to the assembly body 1 with five degrees of freedom in a narrow space is realized.
