[0060] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0061] like Figures 1 to 6 As shown, according to an embodiment of the present disclosure, a clamping device is proposed, including: a processing platform 100; a clamping assembly 200, which is arranged on the processing platform 100 and is used to clamp the workpiece to be processed; a first driving assembly 300, which is connected to the processing platform 100 and is used to drive the processing platform 100 to rotate around a first axis; a second driving assembly 400, which is connected to the processing platform 100 and is used to drive the processing platform 100 to rotate around a second axis and / or a third axis; wherein the first axis, the second axis and the third axis intersect with each other.

[0062] The clamping device proposed in the present disclosure includes the aforementioned processing platform 100, the clamping assembly 200, the first drive assembly 300 and the second drive assembly 400; wherein, the clamping assembly 200 can be used to clamp the workpiece to be processed in actual application, and the processing platform 100 can be used as a carrier of the clamping assembly 200 to support the clamping assembly 200 and the workpiece to be processed clamped by the clamping assembly 200, thereby ensuring the position stability of the workpiece to be processed during the processing; the first drive assembly 300 can drive the processing platform 100 to rotate so that the processing platform 100 generates a rotation amount around the first axis, and accordingly, the clamping assembly 200 on the processing platform 100 and the workpiece to be processed clamped by the clamping assembly 200 can synchronously generate a rotation amount around the first axis; the second drive assembly 400 can drive the processing platform 100 to rotate so that the processing platform 100 generates a rotation amount around the second axis, or generates a rotation amount around the third axis, or generates a rotation amount around the second axis and the third axis at the same time, and accordingly, the clamping assembly 200 and the clamping assembly 200 on the processing platform 100 The workpiece to be processed clamped by the holding component 200 can synchronously generate a corresponding amount of rotation; the aforementioned first axis, second axis and third axis are not parallel to each other, so that the processing platform 100 and the clamping component 200 and the workpiece to be processed carried thereon can have rotational freedom in three different directions, and then in actual application, the clamping device can flexibly adjust the posture of the workpiece to be processed relative to the processing tool by utilizing the first drive component 300 and the second drive component 400 to drive the processing platform 100 to rotate, so that the workpiece to be processed can adapt to the cutting action of the processing tool, which is beneficial to reduce the workload of manual filling of gaskets, improve positioning accuracy and positioning reliability, and provide guarantees for the surface processing accuracy of the workpiece to be processed; based on the aforementioned settings, the clamping device proposed in the present disclosure has a higher degree of flexibility and more degrees of freedom of movement, which is beneficial to realize flexible adjustment of the posture of the workpiece to be processed, improve the posture adjustment efficiency of the workpiece, and reduce the difficulty of posture adjustment of the workpiece, improve the positioning accuracy and positioning reliability of the workpiece, and provide guarantees for the surface processing accuracy of the workpiece to be processed.

[0063] It should be noted that Figure 1 The solid line segment F1 with an arrow in the middle is used to schematically represent the clamping device in Figure 1 the direction of the first axis in the illustrated posture; Figure 1 The solid line segment F2 with an arrow in the middle is used to schematically represent the clamping device in Figure 1 the direction of the second axis in the illustrated posture; Figure 1 The solid line segment F3 with an arrow in the middle is used to schematically represent the clamping device in Figure 1 The direction of the third axis under the posture is shown.

[0064] It can be understood that based on the above-mentioned settings, the rotation movement of the processing platform 100 around the second axis and the rotation movement around the third axis can both be driven by the second drive component 400, thereby reducing the number of different forms of drive components used and the structural complexity of the clamping device, which is conducive to reducing the manufacturing cost and use cost of the clamping component.

[0065] It is understandable that the workpiece to be processed may be, but is not limited to, a workpiece of a thin shell type, a box type, a centrally symmetrical type, or other structural types.

[0066] It is understood that in practical applications, any one of the first, second, and third axes can be set to pass through the plane defined by the other two, thereby further improving the rotational freedom of the processing platform 100 in space. For example, the first, second, and third axes can be set to be perpendicular to each other; or the first and third axes can be set to be perpendicular to the second axis, and the first axis can pass through the plane defined by the second and third axes.

[0067] like Figure 1 and Figure 2 As shown, in some examples, the clamping device also includes: a transition platform 500, rotatably connected to the processing platform 100, and the processing platform 100 is suitable for rotating relative to the transition platform 500 around a first axis; wherein the first drive assembly 300 is connected between the processing platform 100 and the transition platform 500.

[0068] In this technical solution, the clamping device can also include the aforementioned transition platform 500; based on the aforementioned setting, the clamping device can use the transition platform 500 to support the first drive component 300 and the processing platform 100, which can improve the movement stability and installation reliability of the processing platform 100. Accordingly, the first drive component 300 can drive the processing platform 100 to rotate around the first axis relative to the transition platform 500, thereby adjusting the posture of the clamping component 200 and the workpiece to be processed clamped by the clamping component 200.

[0069] like Figure 1 and Figure 2 As shown, in some examples, the processing platform 100 includes a first platform body 110, a first connecting flange 120 and a mating block 130, and the mating block 130 is arranged on the first platform body 110; the transition platform 500 includes a second platform body 510 and an arcuate guide rail 520, the second platform body 510 and the first platform body 110 are rotatably connected through the first connecting flange 120, the arcuate guide rail 520 is arranged on the second platform body 510, and the mating block 130 is slidably matched with the arcuate guide rail 520; wherein, the axial direction of the first connecting flange 120 and the axial direction of the arcuate guide rail 520 both extend along the first axis.

[0070] In this technical solution, the processing platform 100 may include the aforementioned first platform body 110, the first connecting flange 120, and the matching block 130, and the transition platform 500 may include the aforementioned second platform body 510 and the aforementioned curved guide rail 520. Based on the aforementioned arrangement, on the one hand, a multi-point structural connection can be achieved between the processing platform 100 and the transition platform 500, thereby further improving the installation reliability of the processing platform 100 on the transition platform 500; on the other hand, based on the matching relationship between the aforementioned matching block 130 and the curved guide rail 520, the rotation of the processing platform 100 around the first axis can be guided and constrained by the curved guide rail 520, thereby further improving the stability of the processing platform 100 when rotating around the first axis, providing a guarantee for accurate and reliable position adjustment of the workpiece to be processed.

[0071] It can be understood that the axial direction of the aforementioned arc guide rail 520 is also the extension direction of the axis of the arc guide rail 520, and the axis of the arc guide rail 520 is perpendicular to the arc radial direction of the arc guide rail 520 and passes through the arc center of the arc guide rail 520; based on the aforementioned setting of this technical solution, the arc guide rail 520 and the first connecting flange 120 can be coaxially arranged, and the axis of the arc guide rail 520 or the first connecting flange 120 is the aforementioned first axis.

[0072] like Figure 1 and Figure 2 As shown, in some feasible examples, the mating block 130 is disposed at the edge of the first platform body 110, the arcuate guide rail 520 is disposed at the edge of the second platform body 510, and the middle portion of the second platform body 510 and the middle portion of the first platform body 110 are rotatably connected via the first connecting flange 120. Based on the above arrangement, the distance between the mating block 130 and the first connecting flange 120 can be increased, and the distance between the arcuate guide rail 520 and the first connecting flange 120 can be increased, thereby expanding the distance between the connection points of the processing platform 100 and the transition platform 500, further enhancing the supporting effect of the transition platform 500 on the processing platform 100, and improving the installation reliability of the processing platform 100 on the transition platform 500.

[0073] like Figure 1As shown, in some feasible examples, the clamping device may further include a first support assembly 700, one end of the first support assembly 700 being fixedly connected to the transition platform 500, and the other end being detachably connected to the processing platform 100. Based on the aforementioned configuration, during the process of the first driving assembly 300 driving the processing platform 100 to rotate around the first axis, the first support assembly 700 may be separated from the processing platform 100 to facilitate the rotation of the processing platform 100. After the processing platform 100 is rotated into place around the first axis, the first support assembly 700 may be connected to the processing platform 100, so that the transition platform 500 can further support the processing platform 100 through the first support assembly 700, which is conducive to further improving the installation reliability of the processing platform 100 on the transition platform 500 and providing a guarantee for the stable processing of the workpiece to be processed.

[0074] like Figure 1 and Figure 2 As shown, in some feasible examples, the clamping device may further include a second support assembly 800 , and the second support assembly 800 includes a plurality of support blocks spaced apart on the processing platform 100 , and the support blocks are used to abut against the workpiece to be processed.

[0075] like Figures 1 to 3 As shown, in some examples, the first drive assembly 300 has a first connection end 301 and a second connection end 302, the first connection end 301 is arranged on the processing platform 100, and the second connection end 302 is hinged to the transition platform 500, the first connection end 301 and the second connection end 302 are both arranged at intervals from the first axis, and the distance between the first connection end 301 and the second connection end 302 is adjustable.

[0076] In this technical solution, the first drive assembly 300 may have the aforementioned first connection end 301 and the aforementioned second connection end 302. Based on the aforementioned setting, the transition platform 500 may be hinged to the first drive assembly 300 and the processing platform 100 at the same time, that is, the transition platform 500 may form a hinged relationship with the processing platform 100 at the aforementioned first axis position on the one hand, and may form a hinged relationship with the first drive assembly 300 by hingedly connecting the aforementioned second connection end 302 on the other hand, and a certain distance may be formed between the hinged position of the transition platform 500 and the processing platform 100 and the hinged position of the transition platform 500 and the first drive assembly 300. Based on this, there is also a certain distance between the first connection end 301 and the first axis, and when the distance between the first connection end 301 and the second connection end 302 is adjustable, the processing platform 100, the transition platform 500 and the first drive assembly 300 may form a triangle with a variable length on one side. Mechanism; when the first drive component 300 is running, the distance between the first connection end 301 and the second connection end 302 will change, so that the angle between the transition platform 500 and the first drive component 300, and the angle between the transition platform 500 and the processing platform 100 will change, and then the first drive component 300 can drive the processing platform 100 to make the processing platform 100 generate a rotation around the first axis; when the first drive component 300 stops running, the distance between the first connection end 301 and the second connection end 302 also stops changing accordingly, so that the lengths of the three sides of the aforementioned triangular mechanism are in a relatively stable state, and then based on the stability of the triangular structure, the posture of the processing platform 100 can be guaranteed to be stable and reliable, which is conducive to the stable placement of the workpiece to be processed during the processing and provides a guarantee for the processing accuracy.

[0077] It can be understood that the hinge axis between the transition platform 500 and the second connecting end 302 is parallel to the aforementioned first axis.

[0078] like Figure 2 and Figure 3 As shown, in some examples, the first drive assembly 300 includes: a first motor 310; a first mounting base 320, having a first connecting end 301; a first screw 330, rotatably disposed on the first mounting base 320, and the first motor 310 is used to drive the first screw 330 to rotate; a first slider 340, transmission-connected to the first screw 330 and suitable for axial movement along the first screw 330; a first guide rod 350, one end of the first guide rod 350 is connected to the first slider 340, and the other end is a second connecting end 302.

[0079] In this technical solution, the first drive assembly 300 may include the aforementioned first motor 310, first mounting seat 320, first lead screw 330, first slider 340 and first guide rod 350; based on the aforementioned setting, when the first motor 310 is running, it can drive the first lead screw 330 to rotate relative to the first mounting seat 320, thereby driving the first slider 340 and the first guide rod 350 arranged on the first slider 340 to move along the axial direction of the first lead screw 330, thereby changing the relative position between the first guide rod 350 and the first mounting seat 320, thereby realizing the adjustment of the spacing between the first connection end 301 and the second connection end 302, and the lead screw transmission has good self-locking properties, which is conducive to ensuring the relative position between the first connection end 301 and the second connection end 302 is stable when the first motor 310 stops running, thereby ensuring that the position of the processing platform 100 is stable and reliable, which is conducive to the stable placement of the workpiece to be processed during the processing process, and providing a guarantee for the processing accuracy.

[0080] It is understandable that the second connection end 302 can be directly hinged to the transition platform 500 or indirectly hinged to the transition platform 500. For example, Figure 3 As shown, the first drive assembly 300 may further include an articulated seat 360 and a push plate 370 , wherein the articulated seat 360 is fixedly connected to the aforementioned second connection end 302 , the push plate 370 is rotatably connected to the articulated seat 360 , and the push plate 370 is fixedly disposed on the transition platform 500 .

[0081] Exemplarily, the first screw 330 may be a ball screw.

[0082] like Figure 3 As shown, in some feasible examples, the first drive assembly 300 may further include a first guide rail 380 , which is disposed on the first mounting seat 320 and extends axially along the first lead screw 330 , and the first slider 340 slides in cooperation with the first guide rail 380 .

[0083] like Figure 3 As shown, in some feasible examples, the first driving assembly 300 may further include a first reducer 390 , and the first reducer 390 is transmission-connected between the first motor 310 and the first lead screw 330 .

[0084] like Figure 1 and Figure 2 As shown, in some examples, the clamping device also includes: a mounting platform 600, movably connected to the transition platform 500, the transition platform 500 being suitable for rotating relative to the mounting platform 600 around a first axis and / or a second axis; wherein the second drive assembly 400 is connected between the mounting platform 600 and the transition platform 500.

[0085] In this technical solution, the clamping device can also include the aforementioned mounting platform 600; based on the aforementioned setting, the clamping device can use the mounting platform 600 to support the second drive component 400 and the transition platform 500. Accordingly, the second drive component 400 can drive the transition platform 500 to rotate around the first axis and / or the second axis, thereby driving the processing platform 100 to generate a corresponding rotation direction, thereby, with the support of the mounting platform 600, being able to improve the motion stability and installation reliability of the transition platform 500 and the processing platform 100.

[0086] like Figure 1 As shown, in some examples, the mounting platform 600 includes: a third platform body 610; a first axle seat 620, disposed on the third platform body 610; a second axle seat 630, disposed on the transition platform 500; a Hooke's hinge shaft 640, including a first rotating shaft and a second rotating shaft, the first rotating shaft being rotatably disposed on the first axle seat 620 and extending along the second axis, the second rotating shaft being rotatably disposed on the second axle seat 630 and extending along the third axis, and the first rotating shaft being fixedly connected to the second rotating shaft.

[0087] In this technical solution, the mounting platform 600 may include the aforementioned third platform body 610, the first axle seat 620, the second axle seat 630 and the Hooke's hinge 640; based on the aforementioned setting, the transition platform 500 can be movably connected to the third platform body 610 through a Hooke's hinge composed of the first axle seat 620, the second axle seat 630 and the Hooke's hinge 640, thereby enabling the transition platform 500 to rotate around the aforementioned second axis and / or the aforementioned third axis while improving the structural compactness of the clamping device.

[0088] It can be understood that, based on the aforementioned setting of this technical solution, the aforementioned second axis can be the axis of the first rotating shaft, and the aforementioned third axis can be the axis of the second rotating shaft.

[0089] It can be understood that both ends of the first rotating shaft may be connected to the first shaft seat 620 , and both ends of the second rotating shaft may be connected to the second shaft seat 630 .

[0090] like Figure 1 As shown, in some feasible examples, the Hooke's hinge shaft 640 is further connected to the transition platform 500 via the second connecting flange 650 , thereby further improving the connection reliability between the Hooke's hinge shaft 640 and the transition platform 500 .

[0091] like Figure 1 、 Figure 2 and Figure 4As shown, in some examples, the second drive assembly 400 has a third connection end 401 and a fourth connection end 402, the third connection end 401 is arranged on the mounting platform 600, and the fourth connection end 402 is hinged to the transition platform 500, the distance between the third connection end 401 and the fourth connection end 402 is adjustable, the third connection end 401 and the fourth connection end 402 are both spaced apart from the second axis, and the third connection end 401 and the fourth connection end 402 are both spaced apart from the third axis; the number of second drive assemblies 400 is multiple, and the multiple second drive assemblies 400 are arranged in an array along the second axis and the third axis, the second axis is perpendicular to the third axis, and the multiple second drive assemblies 400 can operate independently.

[0092] In this technical solution, the distance between the third connection end 401 and the fourth connection end 402 of the second drive component 400 in operation will change. Accordingly, the clamping device can control multiple second drive components 400 to operate independently, so that the distance change between the third connection end 401 and the fourth connection end 402 of at least some of the second drive components 400 will form a difference, thereby changing the angle between the transition platform 500 and the installation platform 600, and realizing the driving of the transition platform 500, so that the transition platform 500 generates a rotation amount around the second axis and / or the third axis, and then drives the processing platform 100 to generate a rotation amount in the corresponding rotation direction, thereby realizing flexible adjustment of the position of the processing platform 100.

[0097] Exemplarily, the second screw 430 may be a ball screw.

[0098] like Figure 1 and Figure 2As shown, in some feasible examples, the clamping device further includes a detection component 900, which is used to detect motion information of the transition platform 500, thereby facilitating control of the operation of the first drive component 300 and the second drive component 400 based on the motion information in actual applications.
