[0034] See attached Figures 1 to 12The present embodiment provides an angle adjustment device, which includes a load plate 1, a connecting plate 2, a base plate 3 and a switching mechanism 6; the load plate 1 is slidably connected to the connecting plate 2 through at least one set of first arc guide rail components 4, and the connecting plate 2 is slidably connected to the base plate 3 through at least one set of second arc guide rail components 5, the first arc guide rail components 4 and the second arc guide rail components 5 are arranged perpendicular to each other, and the swing center of the load plate 1 sliding relative to the connecting plate 2 through the first arc guide rail component 4 coincides with the swing center of the connecting plate 2 sliding relative to the base plate 3 through the second arc guide rail component 5; one end of the switching mechanism 6 is fixedly connected to the load plate 1, and the other end is drivingly connected to the driving device 7, and the switching mechanism 6 is used to convert the linear motion of the driving device 7 into a swing motion of the load plate 1 relative to the connecting plate 2 along the first direction through the first arc guide rail component 4, or into a swing motion of the load plate 1 in cooperation with the connecting plate 2 through the second arc guide rail component 5 relative to the base plate 3 along the second direction.

[0035] The adjustable part to be adjusted is fixed on the load plate 1, the load plate 1 and the connecting plate 2 are slidably connected by at least one set of first arc guide rail components 4, the connecting plate 2 and the bottom plate 3 are slidably connected by at least one set of second arc guide rails 5, and the load plate 1 can be driven and connected with the driving device 7 through the adapter mechanism 6. Driven by the driving device 7, the adapter mechanism 6 converts the linear motion of the driving device 7 into a swinging motion of the load plate 1 relative to the connecting plate 2 along a first direction through the first arc guide rail component 4, or converts the linear motion of the driving device 7 into a swinging motion of the load plate 1 in coordination with the connecting plate 2 in a second direction through the second arc guide rail component 5 relative to the bottom plate 3. By setting the adapter mechanism 6, the stable rotation of the load plate 1 relative to the connecting plate 2 or the swinging motion of the load plate 1 in coordination with the connecting plate 2 relative to the bottom plate 3 is achieved. Stable rotation of the plate 3; in addition, by separately arranging the switching mechanism 6, the load plate 1, the connecting plate 2, the bottom plate 3 and the switching mechanism 6 are independent of each other, so that when the switching mechanism 6, the load plate 1, the connecting plate 2 or the bottom plate 3 are damaged, the corresponding components can be replaced separately, avoiding overall replacement and reducing replacement costs. In addition, the four plates of the traditional angle adjustment platform are simplified to three plates, which simplifies the structure; and the swing center of the load plate 1 along the first circular arc guide rail assembly 4 and the swing center of the connecting plate 2 along the second circular arc guide rail assembly 5 coincide with each other, which solves the problem of the non-coincidence of the swing centers of the angle swinging platform in the prior art along the two directions, thereby improving the adjustment accuracy of the angle adjustment device for the adjustable member, and the structure is compact, which reduces the space occupied by the equipment and reduces the manufacturing cost of the angle adjustment device.

[0036] The driving device 7 includes a first driving end and a second driving end which are axially perpendicular to each other, and the first driving end and the second driving end are respectively arranged in a one-to-one correspondence with the first circular arc guide rail assembly 4 and the second circular arc guide rail assembly 5. Specifically, the first driving end and the second driving end are respectively and independently arranged on one driving device 7, or the driving device 7 includes a first driving device 71 and a second driving device 72, and the first driving end and the second driving end are respectively arranged on the first driving device 71 and the second driving device 72, and the two driving ends are respectively connected to the switching mechanism 6 to realize that the load plate 1 swings relative to the connecting plate 2 in the first direction through the first circular arc guide rail assembly 4, or the load plate 1 cooperates with the connecting plate 2 to swing relative to the bottom plate 3 in the second direction through the second circular arc guide rail assembly 5.

[0037] By providing a first arc guide rail assembly 4, a second arc guide rail assembly 5 and a switching mechanism 6 that cooperate with each other, it is achieved that the four plates of the traditional angle adjustment platform are simplified to three plates. That is, the present application only needs to provide a load plate 1, a connecting plate 2 and a bottom plate 3 to achieve the first direction angle adjustment and the second direction angle adjustment of the part to be adjusted on the load plate 1, thereby making the structure of the angle adjustment device more compact and reducing the overall size of the angle adjustment device.

[0038] In some possible embodiments, at least one group of first circular arc guide rail components 4 and at least one group of second circular arc guide rail components 5 are arranged in the same plane, which can ensure that when the arc curvature of the first circular arc guide rail components 4 and the arc curvature of the second circular arc guide rail components 5 are the same, the swing center of at least one group of first circular arc guide rail components 4 and the swing center of at least one group of second circular arc guide rail components 5 are arranged to coincide with each other. Such an arrangement can improve the installation speed of the first circular arc guide rail components 4 and the second circular arc guide rail components 5.

[0039] The same plane mentioned above may be a mounting surface formed by the same component, or may be a mounting surface formed by different components.

[0040] In some possible embodiments, the transfer mechanism 6 includes a fixed part and a transfer part that are rotatably connected, the fixed part is fixedly connected to the load plate 1; the transfer part is drivably connected to the driving device 7, and is arranged parallel to the load plate 1 in the initial state; the driving device 7 can drive the transfer part to translate, so as to drive the fixed part to cooperate with the load plate 1 to rotate relative to the transfer part. Thus, the linear motion of the driving device 7 is converted into the swinging motion of the load plate 1 relative to the connecting plate 2 along the first direction through the first circular arc guide assembly 4, or the linear motion of the driving device 7 is converted into the swinging motion of the load plate 1 relative to the base plate 3 along the second direction through the second circular arc guide assembly 5 in cooperation with the connecting plate 2.

[0041] In some possible embodiments, the adapter mechanism 6 includes a self-aligning bearing 65, the inner ring of the self-aligning bearing 65 is placed on the adapter portion, and the outer ring of the self-aligning bearing 65 is placed on the fixed portion. The arrangement of the self-aligning bearing 65 can realize the rotational connection between the fixed portion and the adapter portion.

[0042] In some possible embodiments, the portion where the adapter part and the fixed part are rotatably connected forms a ball joint structure. The setting of the ball joint structure can realize the rotatable connection between the fixed part and the adapter part, and the structure is simple.

[0043] In some possible embodiments, Figure 1 , Figure 7 and Figure 8 As shown, the adapter part includes an adapter body 63 rotatably connected to the fixing part, and the adapter body 63 is slidably connected with a first adapter 61 and a second adapter 62 respectively connected to the driving device 7, the first adapter 61 is arranged in parallel with the first circular arc guide assembly 4, and the second adapter 62 is arranged in parallel with the second circular arc guide assembly 5; under the drive of the driving device 7, one of the first adapter 61 and the second adapter 62 and the adapter body slide synchronously relative to the other of the first adapter 61 and the second adapter 62; by setting the load plate 1 to be rotatably connected to the adapter part through the fixing part, under the guiding action of the first circular arc guide assembly 4, the driving device 7 can be moved to the first circular arc guide assembly 4. The linear motion of the drive device 7 is converted into a swinging motion of the load plate 1 relative to the connecting plate 2 along the first direction, or, under the guiding action of the second arc guide rail assembly 5, the linear motion of the drive device 7 is converted into a swinging motion of the load plate 1 in coordination with the connecting plate 2 relative to the base plate 3 along the second direction, thereby ensuring the stability of the angle adjustment of the load plate 1 relative to the base plate 3, and realizing the angle adjustment of the to-be-adjusted member on the load plate 1, and ensuring the angle adjustment accuracy of the to-be-adjusted member. In addition, when the drive device 7 applies a thrust, the adapter body 63 only moves within the plane and does not deflect with the fixing portion, so that the movement of the adapter body 63 does not affect the application of the driving force by the drive device 7.

[0044] like Figure 1 , Figure 7 and Figure 8As shown, the connection axis of the adapter body 63 slidingly connected to the first adapter 61 and the connection axis of the adapter body 63 slidingly connected to the second adapter 62 are arranged vertically, the movement direction of the first driving end of the first driving device 71 connected to the first adapter 61 is the same as the connection axis direction of the adapter body 63 slidingly connected to the second adapter 62, and corresponds to the swing direction of the load plate 1 relative to the connecting plate 2 through the first arc guide rail assembly 4, which can ensure that the first adapter 61 is driven by the first driving device 71 to realize the first adapter 61 to cooperate with the adapter body 63 to slide relative to the second adapter 62, and then realize that the adapter body 63 drives the load plate 1 to swing relative to the connecting plate 2 along the first direction under the guidance of the first arc guide rail assembly 4 through the fixing part, thereby ensuring the smoothness of the load plate 1 in the first direction. The sliding direction of the adapter body 63 relative to the first adapter 61 corresponds to the swing direction of the load plate 1 and the connecting plate 2 relative to the bottom plate 3 through the second arc guide rail assembly 5. Similarly.

[0045] In some possible embodiments, the driving device 7 includes a first driving end and a second driving end respectively arranged corresponding to the first arc guide rail assembly 4 and the second arc guide rail assembly 5, and the first driving end and the second driving end are respectively driven and connected to the first adapter 61 and the second adapter 62.

[0046] In some possible embodiments, the connection axis of the sliding connection between the adapter body 63 and the first adapter 61 is vertically arranged to the connection axis of the sliding connection between the adapter body 63 and the second adapter 62. One end of the fixing portion is fixedly connected to the load plate 1, and the other end thereof is rotatably connected to the adapter body 63. The first adapter 61 is connected to the first driving end of the first driving device 71, the second adapter 62 is connected to the second driving end of the second driving device 72, and the adapter body 63 is indirectly connected to the load plate 1, so that the linear motion of the first driving device 71 is converted into the movement of the first adapter 61 and the adapter body 63 relative to the second adapter 62, so that with the cooperation of the fixing part, the load plate 1 is swung in the first direction relative to the connecting plate 2 under the guidance of the first arc guide rail assembly 4; or, the linear motion of the second driving device 72 is converted into the movement of the second adapter 62 and the adapter body 63 relative to the first adapter 61, so that with the cooperation of the fixing part, the load plate 1 and the connecting plate 2 are swung in the second direction relative to the base plate 3 under the guidance of the second arc guide rail assembly 5, thereby ensuring the stability of the operation of the angle adjustment device.

[0047] Specifically, the adapter also includes a bearing outer ring of the self-aligning bearing 65 .

[0048] like Figure 1As shown, the first adapter 61 is fixedly connected to the first driving end of the first driving device 71, and the moving direction of the first driving end is set parallel to the length direction of the first arc guide rail assembly 4. The first driving end pushes the first adapter 61 to achieve the first adapter 61 to cooperate with the adapter body 63 to slide relative to the second adapter 62; since the first end of the fixed part is fixedly connected to the load plate 1, the second end of the fixed part is rotatably connected to the adapter body 63, and the load plate 1 and the connecting plate 2 are slidably connected through the first arc guide rail assembly 4, under the action of the above-mentioned first driving device 71, the load plate 1 swings relative to the connecting plate 2 through the first arc guide rail assembly 4 to achieve the first direction angle adjustment of the load plate 1.

[0049] The second adapter 62 is fixedly connected to the second driving end of the second driving device 72, and the moving direction of the second driving end is set parallel to the length direction of the second arc guide rail assembly 5. The second driving end pushes the second adapter 62 to realize the sliding of the second adapter 62 and the adapter body 63 relative to the first adapter 61; since the connecting plate 2 and the base plate 3 are slidingly connected through the second arc guide rail assembly 5, under the action of the above-mentioned second driving device 72, the connecting plate 2 cooperates with the load plate 1 to swing relative to the base plate 3 through the second arc guide rail assembly 5 to realize the second direction angle adjustment of the load plate 1.

[0050] In some possible embodiments, Figure 7 As shown, adjacent side walls of the adapter body 63 are respectively provided with a third clearance space 631 and a fourth clearance space 632 . The third clearance space 631 is used to accommodate and install the first adapter 61 , and the fourth clearance space 632 is used to accommodate and install the second adapter 62 .

[0051] In some possible embodiments, Figure 7 As shown, a fixing hole 633 is also provided on the adapter body 63; the third clearance space 631 and the fourth clearance space 632 are arranged around the fixing hole 633, and the fixing hole 633 is used to install the self-aligning bearing 65. In this way, not only can the material of the adapter body 63 be saved and the manufacturing cost of the adapter body 63 be reduced, but also the structure is more compact.

[0052] After the first adapter 61 is installed in the third clearance space 631, there is a gap between the first adapter 61 and the third clearance space 631 to ensure that when the adapter body 63 slides relative to the first adapter 61, the first adapter 61 will not interfere with the side wall of the third clearance space 631 of the adapter body 63, thereby ensuring the smooth sliding of the adapter body 63 relative to the first adapter 61; the same is true for the gap between the second adapter 62 and the third clearance space 631, which will not be repeated here.

[0053] It can be understood that the first adapter 61 can be partially or completely placed in the third clearance space 631 , and the second adapter 62 can be partially or completely placed in the fourth clearance space 632 .

[0054] In some possible embodiments, the first adapter 61 is provided with a first through hole and a first blind hole that are not connected to each other, and the first blind hole is used to connect the first driving end; the second adapter 62 is provided with a second through hole and a second blind hole that are not connected to each other, and the second blind hole is used to connect the second driving end; the adapter body 63 includes a first connecting shaft 634 fixedly arranged on the side wall of the third makeshift space 631 and a second connecting shaft 635 fixedly arranged on the side wall of the fourth makeshift space 632, and after the first connecting shaft 634 passes through the first through hole, the first adapter 61 is slidably connected to the adapter body 63; after the second connecting shaft 635 passes through the second through hole, the second adapter 62 is slidably connected to the adapter body 63; by providing the first blind hole and the first through hole that are not connected to each other, interference between the first driving end and the structure provided in the first through hole can be avoided, thereby ensuring the stability of the operation of the angle adjustment device; the same applies to the second through hole and the second blind hole.

[0055] The axial direction of the first blind hole is perpendicular to the axial direction of the second blind hole, and the axial direction of the first through hole is perpendicular to the axial direction of the second through hole.

[0056] A linear bearing is installed in the first through hole. When the second driving end of the second driving device 72 pushes the second adapter 62, the second adapter 62 can cooperate with the adapter body 63 provided with the first connecting shaft 634 to slide relative to the first adapter 61, which can ensure the smoothness and stability of the sliding of the adapter body 63 relative to the first adapter 61, and avoid the adapter body 63 and the second adapter 62 from getting stuck, thereby avoiding affecting the driving force applied by the second driving device 72. The same is true for the linear bearing installed in the second through hole.

[0057] The axial direction of the first connecting shaft 634 and the axial direction of the second connecting shaft 635 are arranged perpendicularly, and can match the arrangement direction of the first arc guide rail assembly 4 and the second arc guide rail assembly 5. When the first adapter 61 cooperates with the adapter body 63 to slide relative to the second adapter 62, the first driving end drivingly connected to the first adapter 61 and the second arc guide rail assembly 5 are arranged perpendicularly, and the second arc guide rail assembly 5 cannot move, so that the connecting plate 2 connected to the second arc guide rail assembly 5 cannot swing relative to the bottom plate 3. In this way, when the load plate 1 is adjusted relative to the connecting plate 2 in the first direction under the guidance of the first arc guide rail assembly 4, the connecting plate 2 cannot swing relative to the bottom plate 3, thereby ensuring the angle adjustment accuracy of the angle adjustment device in the first direction; similarly, in the first When the second adapter 62 cooperates with the adapter body 63 to slide relative to the first adapter 61, the second driving end drivingly connected to the second adapter 62 is vertically arranged to the first arc guide rail assembly 4, and the first arc guide rail assembly 4 cannot move, so that the load plate 1 connected to the first arc guide rail assembly 4 cannot swing relative to the connecting plate 2. In this way, when the load plate 1 cooperates with the connecting plate 2 to adjust the angle in the second direction relative to the base plate 3 under the guidance of the second arc guide rail assembly 5, the load plate 1 cannot swing relative to the connecting plate 2, thereby ensuring the angle adjustment accuracy of the angle adjustment device in the second direction.

[0058] like Figure 7 As shown, the first connecting protrusion, the second connecting protrusion and the third connecting protrusion are arranged on the side wall of the adapter body 63 at intervals, the third clearance space 631 is arranged between the first connecting protrusion and the second connecting protrusion, and the fourth clearance space 632 is arranged between the second connecting protrusion and the third connecting protrusion. The first connecting protrusion and the third connecting protrusion are connected by an arc-shaped side wall. Since the three connecting protrusions are arranged to fix the first connecting shaft 634 and the second connecting shaft 635, the other side walls of the adapter body 63 are arranged as an arc structure, which can reduce the manufacturing cost.

[0059] In some embodiments, a matching hole is provided at a position of the connecting protrusion corresponding to the connecting shaft, for fixing and connecting the end of the connecting shaft. In other embodiments, the connecting shaft and the adapter body 63 may be an integrated structure.

[0060] like Figure 1As shown, the fixing part includes a fixing member 64 and an inner ring of a self-aligning bearing 65; the self-aligning bearing 65 is arranged in the fixing hole 633, and the self-aligning bearing 65 includes an inner ring of a bearing and an outer ring of a bearing which are rotatably connected, and the outer ring of the bearing is fixedly connected to the inner wall of the fixing hole 633; ​​the fixing member 64 includes a first end fixedly connected to the load plate 1 and a second end fixedly connected to the inner ring of the bearing, and by providing a fixing member matched with the adapter part, it is possible to drive the load plate 1 to swing relative to the connecting plate 2, or to drive the load plate 1 to swing relative to the base plate 3 in coordination with the connecting plate 2, and at the same time, under the drive of the driving device 7, the outer ring of the self-aligning bearing 65 moves horizontally synchronously with the adapter body 63, and the inner ring of the self-aligning bearing 65 and the fixing member 64 swing synchronously, thereby driving the fixing member 64 fixedly connected to the fixing member 64. The load plate 1 performs a swinging motion under the guidance of the arc guide rail assembly, so that when the fixing member 64 drives the load plate 1 to swing, the adapter body 63 only moves in the plane and will not deflect with the fixing member 64, so that when the driving device 7 applies a thrust to the second adapter 62, the second adapter 62 cooperates with the adapter body 63 to slide relative to the linear bearing in the first adapter 61, or, when the driving device 7 applies a thrust to the first adapter 61, the first adapter 61 cooperates with the adapter body 63 to slide relative to the linear bearing in the second adapter 62, so that the adapter can only move in the horizontal plane without angular swing, and thus will not interfere with the driving device 7 in driving, so as not to affect the driving device to apply the driving force, thereby ensuring the stability of the angle adjustment device.

[0061] A through hole is provided at a position of the load plate 1 corresponding to the fixing member 64 , and a screw passes through the through hole and is threadedly connected to the first end of the fixing member 64 , so that the load plate 1 and the fixing member 64 can be quickly installed and removed.

[0062] The fixing member 64 is a connecting block, and the function of the connecting block is to assemble the load plate 1 and the self-aligning bearing 65 in an indirect connection manner, so as to realize the linkage setting of the self-aligning bearing 65, the fixing member 64 and the load plate 1 to make up for the distance difference between the load plate 1 and the self-aligning bearing 65.

[0063] like Fig.12 and Figure 6As shown, the bottom plate 3 is provided with a second clearance space 35, a first matching through hole 32 and a second matching through hole 33 which are interconnected; the adapter mechanism 6 is arranged in the second clearance space 35, and a gap is provided between the adapter mechanism 6 and the bottom plate 3 to avoid interference between the adapter mechanism 6 and the bottom plate 3 during movement, thereby ensuring the stability of the operation of the adapter mechanism 6, and further ensuring the stability of the operation of the angle adjustment device.

In this way, the installation space can be saved, the overall size of the angle adjustment device can be reduced, and the structure is compact.

[0064] The second clearance space 35 is arranged in the middle area of ​​the base plate 3, and the first matching through hole 32 and the second matching through hole 33 are arranged on adjacent side walls of the base plate 3, and correspond to the first driving end and the second driving end respectively; the side wall where the first matching through hole 32 is located is also provided with a first driving device mounting hole, and the side wall where the second matching through hole 33 is located is also provided with a second driving device mounting hole, which are respectively used to fix and install the first driving device 71 and the second driving device 72.

[0065] The plane where the axis of the first mating through hole 32 and the axis of the second mating through hole 33 are located is parallel to the installation plane of the first arc guide rail assembly 4 and the second arc guide rail assembly 5. Such an arrangement can ensure that the first driving end and the second driving end of the driving device 7 are located on the same plane, which is obviously different from the upper and lower arrangement of the driving device in the prior art. The present application arranges the first driving end and the second driving end of the driving device 7 on the same plane, which can make the angle adjustment device structure more compact and reduce the overall size of the angle adjustment device.

[0066] like Figure 2 and Figure 3 As shown, the first arc guide rail assembly 4 and the second arc guide rail assembly 5 are each symmetrically provided with two groups, and the first arc guide rail assembly 4 and the second arc guide rail assembly 5 are both provided with a fixed guide rail and a movable guide rail that are slidably connected; when the load plate 1 swings relative to the connecting plate 2 under the guidance of the first arc guide rail assembly 4 or when the load plate 1 cooperates with the connecting plate 2 to swing relative to the base plate 3 under the guidance of the second arc guide rail assembly 5, the movable guide rail swings with the load plate 1 or the connecting plate 2, and the fixed guide rail remains stationary.

[0067] like Fig.12 and Figure 3 As shown, a protrusion 34 is provided on the side of the base plate 3 facing the load plate 1 , and the protrusion 34 is fixedly connected to the fixed guide rail of the second circular arc guide rail assembly 5 .

[0068] The projection of the protrusion 34 on the horizontal plane at least covers the projection of the fixed rail of the second arc rail assembly 5 on the horizontal plane to ensure the reliability of the fixed rail fixation. When the projection of the protrusion 34 on the horizontal plane and the projection of the moving rail of the second arc rail assembly 5 on the horizontal plane at least partially overlap, a gap is provided between the moving rail and the protrusion 34 to ensure the smoothness of the moving rail when swinging.

[0069] In some embodiments, the projection of the protrusion 34 on the horizontal plane overlaps with the projection of the fixed guide rail of the second arc guide rail assembly 5 on the horizontal plane.

[0070] In other embodiments, the projection of the protrusion 34 on the horizontal plane covers the projection of the fixed guide rail of the second circular arc guide rail assembly 5 on the horizontal plane, and partially overlaps with the projection of the movable guide rail of the second circular arc guide rail assembly 5 on the horizontal plane, and a gap is left between the movable guide rail and the protrusion 34.

[0071] like Fig.12 and Figure 3 As shown, a baffle 31 is provided on the side wall of the bottom plate 3, and the baffle 31 includes a first end detachably fixedly connected to the bottom plate 3 and a second end abutting against the fixed rail of the second circular arc guide rail assembly 5. The baffle 31 abuts against the fixed rail of the second circular arc guide rail assembly 5, which can improve the stability of the sliding connection between the two rails of the second circular arc guide rail assembly 5, and further improve the operation stability of the second circular arc guide rail assembly 5; the detachable assembly mode of the baffle 31 facilitates the installation of the second circular arc guide rail assembly 5, improves the installation speed of the second circular arc guide rail assembly 5, and also facilitates manufacturing and processing, reducing manufacturing costs.

[0072] The baffle 31 , the protrusion 34 and the second arc guide rail assembly 5 are arranged in a one-to-one correspondence.

[0073] In some embodiments, a plurality of abutment holes are provided on the baffle plate 31 at positions corresponding to the second arc guide rail assembly 5. When installing the second arc guide rail assembly 5, the second arc guide rail assembly 5 is first placed on the protrusion 34, and the fixed guide rail in the second arc guide rail assembly 5 is fixedly connected to the protrusion 34. Then, the first end of the baffle plate 31 is fixedly connected to the base plate 3 by fasteners, and then the second end of the baffle plate 31 is abutted against the fixed guide rail of the second arc guide rail assembly 5 by passing the abutment screws through the abutment holes, thereby further improving the stability of the sliding connection between the two guide rails of the second arc guide rail assembly 5.

[0074] like Figure 2 , Figure 3 and Fig.12 As shown, a recessed portion is provided at the position of the bottom plate 3 corresponding to the baffle 31 for making way for the installation of the baffle 31. After the baffle 31 and the bottom plate 3 are installed in coordination, the outer wall of the baffle 31 and the outer wall of the bottom plate 3 are located in the same plane, and the structure is compact.

[0075] In other embodiments, the baffle 31 may be an integrated structure with the bottom plate 3 , that is, the baffle 31 is formed by extending a portion of the outer wall of the bottom plate 3 toward the direction close to the load plate 1 .

[0076] like Figure 3 As shown, a gap is provided between the baffle plate 31 and the connecting plate 2 to provide a clearance space for the swinging motion of the connecting plate 2 and to avoid interference between the connecting plate 2 and the baffle plate 31 during the swinging process.

[0077] like Figures 9 to 12 and Figure 6 As shown, the connecting plate 2 includes a connecting plate body and a second fixing portion 21 formed by the bottom side wall of the connecting plate body extending horizontally outward along the second direction, and the side wall of the connecting plate body connected to the second fixing portion 21 is formed with an abutment position, which is convenient for quickly positioning and installing the fixed guide rail of the first arc guide rail assembly 4; and / or, the top side wall of the connecting plate body is horizontally extended outward along the first direction to form a first fixing portion, and the side wall of the connecting plate body connected to the first fixing portion is formed with an abutment position, which is convenient for quickly positioning and installing the moving guide rail of the second arc guide rail assembly 5; the setting of the abutment position can improve the installation efficiency and accuracy of the first arc guide rail assembly 4 and the second arc guide rail assembly 5.

[0078] like Figure 2 and Figure 3 As shown, the upper surface of the second fixing portion 21 on the connecting plate 2 and the upper surface of the protrusion 34 on the base plate 3 are located in the same horizontal plane, that is, the second fixing portion 21 and the protrusion 34 form an installation plane, which is convenient for positioning and installing the first arc guide rail assembly 4 and the second arc guide rail assembly 5 in the same plane, thereby improving the installation efficiency and accuracy.

[0079] A clearance groove 36 is provided at a position of the bottom plate 3 corresponding to the second fixing portion 21 , and a gap is provided between the second fixing portion 21 and the side wall of the clearance groove 36 to ensure smooth swinging of the connecting plate 2 under the guidance of the second arc guide rail assembly 5 .

[0080] like Fig.11 and Figure 2 As shown, at least one first connecting hole 211 is provided on the connecting plate body, and the movable guide rail of the second circular arc guide rail assembly 5 is fixedly connected to the connecting plate 2 by the cooperation of the fastener and the first connecting hole 211; at least one second connecting hole 212 is provided on the second fixing portion 21, and the fixed guide rail of the first circular arc guide rail assembly 4 is fixedly connected to the connecting plate 2 by the cooperation of the fastener and the second connecting hole 212.

[0081] When there are more than two first connecting holes 211 and more than two second connecting holes 212, the arrangement direction of at least two first connecting holes 211 is perpendicular to the arrangement direction of at least two second connecting holes 212, the arrangement direction of at least two first connecting holes 211 is consistent with the length direction of the second circular arc guide rail assembly 5, and the arrangement direction of at least two second connecting holes 212 is consistent with the length direction of the first circular arc guide rail assembly 4.

[0082] like Fig.10 and Figure 6 As shown, in some possible embodiments, the connecting plate body is provided with a first clearance space 22, the bottom plate 3 is provided with a second clearance space 35 communicating with the first clearance space 22, and part of the switching mechanism 6 is provided in the first clearance space 22. Specifically, the fixing portion connected to the switching portion extends into the first clearance space 22 and is connected to the load plate 1.

[0083] After the connecting plate 2 and the base plate 3 are connected by the second arc guide rail assembly 5, the first clearance space 22 of the connecting plate 2 and the second clearance space 35 of the base plate 3 are communicated, the driving end of the driving device 7 extends into the second clearance space 35 and is connected to the adapter portion arranged in the second clearance space 35, and the fixing portion is connected to the adapter portion and then extends into the first clearance space 22 to be connected to the load plate 1.

[0084] like Figure 1 and Figure 2 As shown, the load plate 1 includes an abutment portion extending from its side wall toward one side of the bottom plate 3, and the abutment portion is fixedly connected to the movable guide rail of the first circular arc guide rail assembly 4, which not only enables the load plate 1 to swing synchronously with the movable guide rail of the first circular arc guide rail assembly 4, but also the abutment portion limits the movable guide rail, thereby further ensuring the stability of the operation of the first circular arc guide rail assembly 4.

[0085] At least one set of first arc guide rail assembly 4 and at least one set of second arc guide rail assembly 5 are both arranged on the side of the bottom plate 3 facing the connecting plate 2. The first arc guide rail assembly 4 includes a first guide rail 41 and a second guide rail 42 which are slidably connected, one of the first guide rail 41 and the second guide rail 42 is fixedly connected to the load plate 1, and the other is fixedly connected to the connecting plate 2; the second arc guide rail assembly 5 includes a third guide rail 51 and a fourth guide rail 52 which are slidably connected, one of the third guide rail 51 and the fourth guide rail 52 is fixedly connected to the connecting plate 2, and the other is fixedly connected to the bottom plate 3, so that the load plate 1 and the connecting plate 2 are relatively swung, and the connecting plate 2 and the bottom plate 3 are relatively swung, thereby ensuring the stability of the angle adjustment process.

[0086] like Figure 3 and Figure 4 As shown, the first guide rail 41 and the third guide rail 51 correspond to movable guide rails, and the second guide rail 42 and the fourth guide rail 52 correspond to fixed guide rails.

[0087] The fixed surfaces of the fixed guide rail and the movable guide rail are planes, and the surfaces opposite to the fixed surfaces are arc surfaces or planes. Compared with the structure in which both the upper and lower surfaces of the circular guide rail are arc surfaces, it is easier to process and assemble, and further improves the installation speed.

[0088] like Figure 1 As shown, the angle adjustment device includes two groups of first arc guide rail assemblies 4 and two groups of second arc guide rail assemblies 5 arranged opposite to each other, and the arrangement direction of the two groups of first arc guide rail assemblies 4 is arranged perpendicularly to the arrangement direction of the two groups of second arc guide rail assemblies 5; the length direction of the first arc guide rail assembly 4 is arranged parallel to the axial direction of the first driving end of the driving device 7, and the first driving end can drive the load plate 1 to swing relative to the connecting plate 2 through the first arc guide rail assembly 4, and because the length direction of the second arc guide rail assembly 5 is arranged perpendicularly to the axial direction of the first driving end, the second arc guide rail assembly 5 It can limit the connection plate 2, so that the load plate 1 can swing relative to the connection plate 2 along the first direction; the length direction of the second arc guide rail assembly 5 is parallel to the axial direction of the second driving end of the driving device 7, and the second driving end can drive the load plate 1 to cooperate with the connection plate 2 to swing relative to the bottom plate 3 through the second arc guide rail assembly 5, and because the length direction of the first arc guide rail assembly 4 is perpendicular to the axial direction of the second driving end, the first arc guide rail assembly 4 can limit the load plate 1, so that the load plate 1 can cooperate with the connection plate 2 to swing relative to the bottom plate 3 along the second direction. Among them, the first direction corresponds to the sliding direction of the moving guide rail in the first arc guide rail assembly 4, and the second direction corresponds to the sliding direction of the moving guide rail in the second arc guide rail assembly 5.

[0089] like Figure 6 As shown, when the angle adjustment device is in the initial state, the load plate 1 , the connecting plate body, the second fixing portion 21 , the protrusion 34 and the adapter body 63 are all arranged in parallel, and the axis of the driving end of the driving device 7 passes through the adapter body 63 .

[0090] When the angle adjustment device is adjusted from the initial state to the working state, the driving device 7 drives the adapter body 63 to translate, and the fixing member 64 rotatably connected to the adapter body 63 rotates a certain angle relative to the adapter body 63, thereby driving the load plate 1 to rotate a certain angle relative to the connecting plate 2, or driving the load plate 1 to rotate a certain angle in coordination with the connecting plate 2 relative to the base plate 3.

[0091] The second aspect of the present invention also protects an angle adjustment device, including a driving device 7 and the above angle adjustment device, the driving device 7 includes a first driving end and a second driving end, which respectively correspond to the driving adapter mechanism 6 to translate along the first direction or the second direction.

[0092] The driving device 7 connected to the switching mechanism 6 is a manual adjustment device or an automatic adjustment device, and the driving end of the driving device 7 can move toward or away from the switching mechanism 6 .

[0093] The automatic adjustment device can be a push rod motor. By adjusting the extension length of the first driving end of the push rod motor, the load plate 1 is pushed through the first arc guide assembly 4 to adjust the angle relative to the connecting plate 2 through the adapter mechanism 6, thereby achieving fine adjustment of the angle of the part to be adjusted on the load plate 1 in the first direction; by adjusting the extension length of the second driving end of the push rod motor, the load plate 1 is pushed through the adapter mechanism 6 to coordinate with the connecting plate 2 to adjust the angle relative to the bottom plate 3 through the second arc guide assembly 5, thereby achieving fine adjustment of the angle of the part to be adjusted on the load plate 1 in the second direction, effectively improving the angle adjustment accuracy of the angle adjustment device on the part to be adjusted, and at the same time, by controlling the movement of the push rod motor, it is possible to achieve automatic adjustment of the part to be adjusted, further improving the angle adjustment rate and angle adjustment accuracy of the part to be adjusted.

[0094] The angle adjustment process of the angle adjustment device is as follows: The first driving end of the push rod motor fixedly connected to the first adapter 61 pushes the first adapter 61, and the first adapter 61 cooperates with the adapter body 63 to slide relative to the second adapter 62. Since the second arc guide rail assembly 5 is vertically arranged to the first driving end, the connecting plate 2 connected to the second arc guide rail assembly 5 cannot swing relative to the base plate 3 through the second arc guide rail assembly 5; and since the first arc guide rail assembly 4 is parallel to the first driving end, the load plate 1 connected to the first arc guide rail assembly 4 can swing relative to the connecting plate 2 through the first arc guide rail assembly 4, thereby realizing the first direction angle adjustment of the part to be adjusted on the load plate 1.

[0095] The second driving end of the push rod motor fixedly connected to the second adapter 62 pushes the second adapter 62, and the second adapter 62 cooperates with the adapter body 63 to slide relative to the first adapter 61. Since the first arc guide rail assembly 4 is vertically arranged to the second driving end, the load plate 1 connected to the first arc guide rail assembly 4 cannot swing relative to the connecting plate 2 through the first arc guide rail assembly 4; and since the second arc guide rail assembly 5 is parallelly arranged to the second driving end, the connecting plate 2 connected to the second arc guide rail assembly 5 can swing synchronously with the load plate 1 relative to the base plate 3 through the second arc guide rail assembly 5, thereby realizing the second direction angle adjustment of the part to be adjusted on the load plate 1.

[0096] The order of adjusting the angles of the first direction and the second direction of the adjustable part on the load plate 1 is not limited.

[0097] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.

[0098] In the absence of conflict, the above embodiments and features in the embodiments can be combined with each other.

[0099] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
