Furthermore, unless explicitly defined herein, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the relevant art and the content of this application, and will not be interpreted as an idealized or overly formal meaning.

[0063] Generally, in view of the current diversified product development needs of customers and the urgent need for samples, ordinary fixture designs cannot meet the needs of rapid sample preparation, and some samples require multi-angle processing. Generally, a four-axis machining mechanism can only swing in two directions and usually cannot swing in four directions. In order to achieve an angle swing in more than two directions in the existing technology, a 4.5-axis or 5-axis turntable is usually required, and the cost of such a turntable is generally high. How to solve the above problems is what those skilled in the art need to consider.

[0064] Correspondingly, an embodiment of the present application provides a movable fixing mechanism, comprising a bottom plate, a base plate, a rotating connection assembly, and two lifting assemblies. The bottom plate is used to carry materials; the base plate is spaced apart from the bottom plate so that there is a movable gap between the bottom plate and the base plate; the rotating connection assembly is disposed between the bottom plate and the base plate, the rotating connection assembly comprising a fixed portion and a rotating portion, the rotating portion being rotatably connected to the fixed portion, the fixed portion being connected to the base plate, and the rotating portion being connected to the bottom plate; two lifting assemblies are spaced apart on opposite sides of the rotating connection assembly and are respectively connected to the base plate, the two lifting assemblies each being in detachable contact with the bottom plate, and being used to rotate the bottom plate relative to the base plate.

[0065] Therefore, in the present application's movable fixing mechanism, a base plate is used to support the material. The base plate and base plate are movably connected via a rotating connection assembly. A movable gap is provided between the base plate and the base plate, allowing the base plate to rotate relative to the base plate, thereby allowing the material to swing more freely during subsequent processing. Simultaneously, two lifting assemblies are each detachably in contact with the base plate. The two lifting assemblies can each abut one end of the base plate, allowing the base plate to rotate relative to the base plate about the rotating connection assembly as an axis; that is, the base plate drives the material to swing.

[0066] The following describes exemplary embodiments with reference to the accompanying drawings. It should be noted that the components depicted in the accompanying drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0067] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0068] like Figures 1 to 4 As shown, an embodiment of the present application provides a movable fixing mechanism 10, comprising a base plate 11, a base plate 12, a rotating connection assembly 13, two lifting assemblies 14, and two lateral displacement assemblies 15. The rotating connection assembly 13, the two lifting assemblies 14, and the two lateral displacement assemblies 15 are all connected to the base plate 12, and the base plate 11 is rotatably connected to the base plate 12 via the rotating connection assembly 13. The two lifting assemblies 14 are spaced apart on opposite sides of the rotating connection assembly 13, and the two lateral displacement assemblies 15 are disposed on opposite sides of the rotating connection assembly 13, and each lateral displacement assembly 15 is disposed between the rotating connection assembly 13 and a lifting assembly 14.

[0069] In one embodiment, the bottom plate 11 is used to carry materials, and the base plate 12 is spaced apart from the bottom plate 11, so that a movable gap 122 is defined between the bottom plate 11 and the base plate 12. A rotating connection assembly 13 is disposed between the bottom plate 11 and the base plate 12. The rotating connection assembly 13 includes a fixed portion 131 and a rotating portion 132. The rotating portion 132 is rotatably connected to the fixed portion 131. The fixed portion 131 is connected to the base plate 12, and the rotating portion 132 is connected to the bottom plate 11, so that the base plate 12 and the bottom plate 11 have a spatial structure that allows relative rotation. Two lifting assemblies 14 are spaced apart on opposite sides of the rotating connection assembly 13 and are respectively connected to the base plate 12. The two lifting assemblies 14 are each in detachable contact with the bottom plate 11 and are used to rotate the bottom plate 11 relative to the base plate 12.

[0070] It is understood that in the movable fixing mechanism 10 of the present application, the bottom plate 11 is used to carry the material. The bottom plate 11 and the base plate 12 are movably connected by a rotating connecting assembly 13. At the same time, there is a movable gap 122 between the bottom plate 11 and the base plate 12, which enables the bottom plate 11 to rotate relative to the base plate 12, thereby allowing the material to have a freer swing angle during subsequent processing. At the same time, the two lifting assemblies 14 are each in detachable contact with the bottom plate 11. The two lifting assemblies 14 can respectively support the two ends of the bottom plate 11, allowing the bottom plate 11 to rotate relative to the base plate 12 with the rotating connecting assembly 13 as the axis; that is, the bottom plate 11 drives the material to swing.

[0071] In this embodiment, the movable fixing mechanism 10 further includes a rotating platform 16, to which the base plate 12 is connected. The platform 16, through the base plate 12, can drive the bottom plate 11 connected thereto, as well as the material disposed on the bottom plate 11, to rotate. Simultaneously, the bottom plate 11, base plate 12, rotating connection assembly 13, two lifting assemblies 14, and two lateral displacement assemblies 15 cooperate to achieve the swinging of the material driven by the bottom plate 11. This allows the movable fixing mechanism 10 of this application to accommodate angular machining in two or more directions. When used in conjunction with a standard four-axis turntable, this significantly reduces the cost of the turntable and platform 16.

[0072] In one embodiment, the bottom plate 11 includes a carrying portion 111 and a connecting portion 112 . The carrying portion 111 is located on a side of the connecting portion 112 away from the base plate 12 . The carrying portion 111 is used to carry materials. The connecting portion 112 is connected to the rotating portion 132 .

[0073] In this embodiment, the support portion 111 can be a plate-like structure with a built-in vacuum adsorption unit (not shown). The side of the support portion 111 away from the connection portion 112 is used to support materials. If necessary, the surface of the support portion 111 supporting the materials can generate negative pressure to enhance the material's suction. The connection portion 112 is connected to the side of the support portion 111 facing the base plate 12. The connection portion 112 is generally plate-shaped and is stacked with the support portion 111 to maintain the stability of the base plate 11 structure.

[0074] In one embodiment, a connecting protrusion 1121 is provided on the side of the connecting portion 112 facing the rotating portion 132. The rotating portion 132 is connected to the middle portion of the side of the bottom plate 11 facing the base plate 12. The rotating portion 132 includes a rotating shaft 1321. The connecting protrusion 1121 is provided on the surface of the rotating shaft 1321 facing the bottom plate 11 and is fixedly connected to the rotating shaft 1321.

[0075] In this embodiment, the fixed portion 131 includes a fixed block 1311, a front cover 1313, and a rear cover 1314. The fixed block 1311 defines a rotation chamber 1312. The rotating portion 132 also includes a bearing 1324, which is disposed in the rotation chamber 1312. The rotating shaft 1321 includes two connecting ends 1322 located on both sides and a connecting block 1323 located in the middle. The two connecting ends 1322 are respectively disposed in one rotation chamber 1312 and are rotatably connected to the fixed block 1311 via a bearing 1324. The front cover 1313 and the rear cover 1314 are spaced apart on both sides of the fixed block 1311 to secure the bearing 1324 in the rotation chamber 1312. The connecting block 1323 is semi-cylindrical, and the connecting protrusion 1121 is connected to the flat portion of the semi-cylindrical connecting block 1323.

[0076] As can be understood, the two fixing portions 131 are respectively mounted on opposite sides of the same surface of the base plate 12, the rotating shaft 1321 is disposed between the two fixing portions 131, and the two connecting ends 1322 are each rotatably connected to a fixing block 1311 via a bearing 1324. Simultaneously, the front cover 1313 and the rear cover 1314 are respectively disposed on opposite sides of the fixing block 1311, cooperating to cover the rotating cavity 1312. The two ends of the connecting block 1323 are respectively connected to the two connecting ends 1322, the connecting protrusion 1121 is connected to the flat portion of the semi-cylindrical connecting block 1323, and the connecting protrusion 1121 is simultaneously located between the two connecting ends 1322. The surface of the connecting protrusion 1121 facing the connecting block 1323 is a flat portion, which abuts against the flat portion of the connecting block 1323. The connecting protrusion 1121 is further fixedly connected to the rotating shaft 1321 via bolts (not shown). This structure can not only ensure that the connection between the connecting portion 112 and the rotating portion 132 is stable, but also appropriately reduce the overall height of the movable fixing mechanism 10 .

[0077] In one embodiment, the lifting assembly 14 includes a lifting drive 141 and a lifting rod 142. The lifting drive 141 is fixedly connected to the base plate 12. The lifting rod 142 is driven by the lifting drive 141 to move relative to the bottom plate 11. The top end of the lifting rod 142 is in detachable contact with the surface of the bottom plate 11 facing the base plate 12, thereby driving the bottom plate 11 to rotate about the rotating connecting assembly 13.

[0078] In this embodiment, the lifting drive member 141 can be a cylinder. In other embodiments, the lifting drive member 141 can also be other feasible driving units such as a motor. The lifting rod 142 is driven by the lifting unit and has the ability to perform linear motion.

[0079] As can be understood, the lifting drive member 141 is connected to the base plate 12 and can be arranged on the side of the base plate 12 away from the bottom plate 11, with the lifting rods 142 extending toward the side closer to the bottom plate 11. The lifting rods 142 contact the bottom plate 11 and push the bottom plate 11 to rotate about the rotating portion 132 as the rotation axis. The two spaced lifting rods 142 lift the bottom plate 11 from both sides, respectively, and the direction and amplitude of the rotation of the bottom plate 11 can be adjusted.

[0080] In one embodiment, two contoured grooves 1111 are formed on the surface of the bottom plate 11 facing the base plate 12. The two contoured grooves 1111 are respectively located on opposite sides of the rotating portion 132. The top of the lifting rod 142 has a contoured protrusion 143. One contoured protrusion 143 is correspondingly matched with one contoured groove 1111.

[0081] It is understood that the two contoured grooves 1111 are respectively located at the two side ends of the bearing portion 111, and the two lifting rods 142 are respectively provided corresponding to the two contoured grooves 1111. By matching the contoured structure, it is possible to guide the lifting rods 142 to contact the bottom plate 11 and protect the entire structure.

[0082] In one embodiment, the base plate 11 further includes two stoppers 113 connected to the connecting portion 112. The two stoppers 113 are located on opposite sides of the connecting protrusion 1121. Both stoppers 113 are located on the side of the connecting portion 112 facing the base plate 12. The stoppers 113 protrude from the connecting portion 112 toward the side away from the supporting portion 111. The stoppers 113 include a stepped structure 1131 with a height difference, and the stepped structure 1131 is disposed toward the base plate 12.

[0083] In this embodiment, the step structure 1131 includes a convex surface 1132 closer to the base plate 12 and a concave surface 1133 further away from the base plate 12. The convex surface 1132 is closer to the rotating portion 132 than the concave surface 1133. The convex surface 1132 is used to provide support for the base plate 11 when the base plate 11 is in a substantially horizontal state, and the concave surface 1133 is used to limit the position of the base plate 11 when the base plate 11 is in a tilted state.

[0084] In one embodiment, the lateral displacement assembly 15 includes a lateral drive unit 151 and a support block 152. The lateral drive unit 151 is fixedly connected to the base plate 12, and the support block 152 is drivingly connected to the lateral drive unit 151. The support block 152 is movably disposed on the side of the base plate 12 facing the bottom plate 11, and each support block 152 is correspondingly provided with a limit block 113.

[0085] In this embodiment, the transverse drive unit 151 includes a transverse drive member 1511 and a push rod 1512, which are connected in a driving manner. The push rod 1512 is located on the side of the transverse drive member 1511 near the two lifting assemblies 14. The transverse drive member 1511 is connected to the base plate 12. The transverse drive member 1511 and the rotation connection assembly 13 are located on opposite sides of the base plate 12. The base plate 12 has a through hole 121, through which the push rod 1512 passes to connect to the support block 152.

[0086] In one embodiment, the support block 152 includes a support end 1521 protruding toward the bottom plate 11 . The lateral displacement assembly 15 drives the support block 152 to move relative to the rotating portion 132 , so that the support end 1521 corresponds to one of the concave surface 1133 or the convex surface 1132 .

[0087] It is understood that the function of the lateral displacement assembly 15 is to push the support block 152 to move via the lateral drive unit 151, so that the support block 152 can correspond to the moving limit block 113. Furthermore, the lateral drive unit 151 can push the support block 152 to move further, so that the support block 152 can correspond to and contact one of the concave surface 1133 or the convex surface 1132. The height difference of the step structure 1131 limits the travel of the bottom plate 11 during the flipping process.

[0088] In this embodiment, the transverse driving member 1511 and the lifting driving member 141 are arranged on the same side of the base plate 12 away from the bottom plate 11. When the transverse driving member 1511 and the lifting driving member 141 are both cylinders, this design structure can facilitate the layout of the pipeline; at the same time, it can minimize the interference of the transverse driving member 1511 and the lifting driving member 141 with the flipping of the bottom plate 11.

[0089] In this embodiment, push rod 1512 has a bent structure. One end of push rod 1512 connects to transverse drive member 1511, while the other end bends and passes through through-hole 121 to connect to the bottom of support block 152. Through-hole 121 is at least one long strip to prevent interference with the movement of push rod 1512. The end of push rod 1512 away from transverse drive member 1511 can extend into the interior of support block 152, strengthening the connection with support block 152 and simplifying the structure.

[0090] The following describes the movement of the movable fixing mechanism 10 by taking an actuation process of the movable fixing mechanism 10 according to an embodiment of the present application as an example:

[0091] like Figure 5 As shown, the support end 1521 of the left support block 152 abuts against the convex surface 1132 of the left limit block 113, and the contoured protrusion 143 of the right lifting rod 142 abuts against the contoured groove 1111 on the right side of the bearing part 111, and the bottom plate 11 remains roughly horizontal.

[0092] like Figure 6 As shown, the right lifting rod 142 falls back, and the right supporting block 152 moves rightward to correspond to the concave surface 1133 of the right limiting block 113.

[0093] like Figure 7 As shown, the left lifting rod 142 is pushed upward, and the contoured protrusion 143 of the left lifting rod 142 is pressed against the contoured groove 1111 on the left side of the bearing part 111. The base plate 11 rotates around the rotating connecting assembly 13, and the right side of the bearing part 111 descends. The supporting end 1521 of the right supporting block 152 is pressed against the concave surface 1133 of the right limit block 113, completing the negative direction movement.

[0094] like Figure 8 As shown, the left lifting rod 142 falls back, and the left supporting block 152 moves leftward to correspond to the concave surface 1133 of the left limiting block 113.

[0095] like Figure 9 As shown, the right lifting rod 142 is pushed upward, and the contoured protrusion 143 of the right lifting rod 142 is abutted against the contoured groove 1111 on the right side of the bearing part 111. The base plate 11 rotates around the rotating connecting assembly 13, and the left side of the bearing part 111 descends. The supporting end 1521 of the left supporting block 152 is abutted against the concave surface 1133 of the left limiting block 113, completing the positive direction movement.

[0096] like Figure 10 As shown, the right lifting rod 142 is first partially lowered, and then the left supporting block 152 is moved rightward to correspond to the convex surface 1132 of the left limiting block 113, completing the movement in the horizontal plane direction.

[0097] It is understandable that the above “up”, “down”, “left” and “right” are based on Figures 5 to 10 The plan view shown is placed forwardly as a reference. The movable fixing mechanism 10 of the present application controls the movement of the bottom plate 11 relative to the base plate 12 by cooperating with the lifting component 14 on one side and the lateral displacement component 15 on the other side.

[0098] The specific embodiments of the present application have been described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and substitutions may be made to the specific embodiments of the present application without departing from the spirit and scope of the present application. Such modifications and substitutions are intended to fall within the scope of the present application.
