[0060] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0061] like Figures 1 to 6 As shown, according to an embodiment of this disclosure, a clamping device is provided, including: a processing platform 100; a clamping assembly 200 disposed on the processing platform 100 for clamping a workpiece to be processed; a first driving assembly 300 connected to the processing platform 100 for driving the processing platform 100 to rotate around a first axis; and a second driving assembly 400 connected to the processing platform 100 for driving 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 each other.
[0062] The clamping device disclosed herein includes the aforementioned processing platform 100, clamping assembly 200, first driving assembly 300, and second driving assembly 400. In practical applications, the clamping assembly 200 can clamp the workpiece to be processed, and the processing platform 100 can serve as a carrier for the clamping assembly 200, supporting both the clamping assembly 200 and the workpiece clamped therein, thereby ensuring the positional stability of the workpiece during processing. The first driving assembly 300 can drive the processing platform 100 to rotate, causing the processing platform 100 to rotate about a first axis. Correspondingly, the clamping assembly 200 on the processing platform 100 and the workpiece clamped therein can simultaneously rotate about the first axis. The second driving assembly 400 can drive the processing platform 100 to rotate, causing the processing platform 100 to rotate about a second axis, or about a third axis, or simultaneously about both axes. Correspondingly, the clamping assembly 200 on the processing platform 100 and the workpiece clamped therein can simultaneously rotate about the first axis. The workpiece to be processed clamped by the holding component 200 can synchronously generate corresponding rotational amounts. The aforementioned first axis, second axis, and third axis are not parallel to each other, so the processing platform 100, the clamping component 200 and the workpiece to be processed carried on it can have rotational degrees of freedom in three different directions. Therefore, in practical applications, the clamping device can flexibly adjust the position of the workpiece to be processed relative to the processing tool by using the first driving component 300 and the second driving 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. This helps to reduce the workload of manually filling shims, improve positioning accuracy and positioning reliability, and provide a guarantee for the surface processing accuracy of the workpiece to be processed. Based on the aforementioned settings, the clamping device proposed in this disclosure has a high degree of flexibility and a large number of motion degrees of freedom, which is conducive to realizing flexible adjustment of the position of the workpiece to be processed, improving the efficiency of workpiece position adjustment, reducing the difficulty of workpiece position adjustment, improving the positioning accuracy and positioning reliability of the workpiece, and providing a guarantee 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 arrowhead is used to schematically indicate that the clamping device is in... Figure 1 The direction of the first axis in the shown posture; Figure 1 The solid line segment F2 with an arrowhead is used to schematically indicate the clamping device in... Figure 1 The direction of the second axis in the shown posture; Figure 1 The solid line segment F3 with an arrowhead is used to schematically indicate the clamping device in... Figure 1 The direction of the third axis in the shown posture.
[0064] It is understandable that, based on the aforementioned setup, the rotation of the processing platform 100 around the second axis and the rotation of the processing platform 100 around the third axis can both be driven by the second drive component 400, thereby reducing the number of different types of drive components used and the structural complexity of the clamping device, which is beneficial to reducing the manufacturing and usage costs of the clamping components.
[0065] It is understood that the workpieces to be processed can be, but are not limited to, thin-shell, box-shaped, or centrally symmetrical structures.
[0066] It is understood that, in practical applications, any one of the aforementioned first axis, second axis, and third axis can be configured to pass through the plane defined by the other two, thereby further enhancing the rotational freedom of the processing platform 100 in space. For example, the aforementioned first axis, second axis, and third axis can be configured to be mutually perpendicular; or, the first axis and third axis can be configured to be perpendicular to the second axis, with the first axis passing through the plane formed by the second axis and third axis.
[0067] like Figure 1 and Figure 2 As shown, in some examples, the clamping device further includes: a transition platform 500 rotatably connected to the machining platform 100, the machining platform 100 being adapted to rotate relative to the transition platform 500 about a first axis; wherein a first drive assembly 300 is connected between the machining platform 100 and the transition platform 500.
[0068] In this technical solution, the clamping device may further include the aforementioned transition platform 500. Based on the aforementioned configuration, the clamping device can utilize the transition platform 500 to support the first drive assembly 300 and the processing platform 100, thereby improving the motion stability and installation reliability of the processing platform 100. Correspondingly, the first drive assembly 300 can drive the processing platform 100 to rotate relative to the transition platform 500 around the first axis, thereby adjusting the position of the clamping assembly 200 and the workpiece to be processed clamped by the clamping assembly 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, with the mating block 130 disposed on the first platform body 110; the transition platform 500 includes a second platform body 510 and an arc-shaped guide rail 520, with the second platform body 510 and the first platform body 110 rotatably connected via the first connecting flange 120, the arc-shaped guide rail 520 disposed on the second platform body 510, and the mating block 130 slidingly engaging with the arc-shaped guide rail 520; wherein, the axial direction of both the first connecting flange 120 and the arc-shaped guide rail 520 extends along a first axis.
[0070] In this technical solution, the machining platform 100 may include the aforementioned first platform body 110, first connecting flange 120, and mating block 130, while the transition platform 500 may include the aforementioned second platform body 510 and the aforementioned arc-shaped guide rail 520. Based on the aforementioned configuration, on the one hand, a multi-point structural connection can be achieved between the machining platform 100 and the transition platform 500, thereby further improving the installation reliability of the machining platform 100 on the transition platform 500; on the other hand, based on the mating relationship between the aforementioned mating block 130 and the arc-shaped guide rail 520, the rotation of the machining platform 100 around the first axis can be guided and constrained by the arc-shaped guide rail 520, thereby further improving the stability of the machining platform 100 when rotating around the first axis and providing a guarantee for the accurate and reliable position adjustment of the workpiece to be processed.
[0071] It is understood that the axial direction of the aforementioned arc-shaped guide rail 520 is also the extension direction of the axis of the arc-shaped guide rail 520. The axis of the arc-shaped guide rail 520 is perpendicular to the radial direction of the arc of the arc-shaped guide rail 520 and passes through the center of the arc of the arc of the arc-shaped guide rail 520. Based on the aforementioned arrangement of this technical solution, the arc-shaped guide rail 520 and the first connecting flange 120 can be arranged coaxially, and the axis of the arc-shaped 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 arc-shaped guide rail 520 is disposed at the edge of the second platform body 510, and the middle part of the second platform body 510 and the middle part of the first platform body 110 are rotatably connected by the first connecting flange 120. Based on the aforementioned configuration, the distance between the mating block 130 and the first connecting flange 120, and the distance between the arc-shaped guide rail 520 and the first connecting flange 120 can be increased, thereby expanding the spacing between the connection points of the processing platform 100 and the transition platform 500, further improving the support 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 component 700, one end of which is fixedly connected to the transition platform 500, and the other end is detachably connected to the machining platform 100. Based on the aforementioned configuration, during the process of the first drive component 300 driving the machining platform 100 to rotate around the first axis, the first support component 700 can be separated from the machining platform 100 to facilitate the rotation of the machining platform 100. After the machining platform 100 has rotated to its position around the first axis, the first support component 700 can be connected to the machining platform 100, so that the transition platform 500 can further support the machining platform 100 through the first support component 700. This is beneficial to further improve the installation reliability of the machining platform 100 on the transition platform 500 and provide a guarantee for the stable machining of the workpiece to be processed.
[0074] like Figure 1 and Figure 2 As shown, in some feasible examples, the clamping device may also include a second support assembly 800, which includes a plurality of support blocks spaced apart on the machining platform 100 for abutting the workpiece to be machined.
[0075] like Figures 1 to 3 As shown, in some examples, the first drive assembly 300 has a first connecting end 301 and a second connecting end 302. The first connecting end 301 is disposed on the processing platform 100, and the second connecting end 302 is hinged to the transition platform 500. Both the first connecting end 301 and the second connecting end 302 are arranged at intervals from the first axis, and the distance between the first connecting end 301 and the second connecting end 302 is adjustable.
[0076] In this technical solution, the first drive component 300 may have the aforementioned first connecting end 301 and the aforementioned second connecting end 302. Based on the aforementioned configuration, the transition platform 500 can be simultaneously hinged to the first drive component 300 and the processing platform 100. That is, the transition platform 500 can form a hinged relationship with the processing platform 100 at the aforementioned first axis position, and on the other hand, it can form a hinged relationship with the first drive component 300 by hinged to the aforementioned second connecting end 302. Furthermore, a certain interval can be formed between the hinge position of the transition platform 500 and the processing platform 100 and the hinge position of the transition platform 500 and the first drive component 300. Based on this, when there is also a certain interval between the first connecting end 301 and the first axis, and the distance between the first connecting end 301 and the second connecting end 302 is adjustable, the processing platform 100, the transition platform 500, and the first drive component 300 can form a triangle with a variable side length. The mechanism is such that when the first drive assembly 300 is running, the distance between the first connecting end 301 and the second connecting end 302 changes, thereby changing the angle between the transition platform 500 and the first drive assembly 300, as well as the angle between the transition platform 500 and the processing platform 100. This allows the first drive assembly 300 to drive the processing platform 100, causing it to rotate around the first axis. When the first drive assembly 300 stops running, the distance between the first connecting end 301 and the second connecting end 302 also stops changing. Thus, the lengths of the three sides of the aforementioned triangular mechanism are in a relatively stable state. Based on the stability of the triangular structure, the position and orientation of the processing platform 100 are guaranteed to be stable and reliable, which is beneficial for the stable placement of the workpiece during processing and provides assurance for processing accuracy.
[0077] It is understood that the hinge axis of the transition platform 500 and the second connection 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 lead screw 330 rotatably disposed on the first mounting base 320, the first motor 310 being used to drive the first lead screw 330 to rotate; a first slider 340 being drively connected to the first lead screw 330 and adapted to move along the axial direction of the first lead screw 330; and a first guide rod 350, one end of the first guide rod 350 being connected to the first slider 340, and the other end being a second connecting end 302.
[0079] In this technical solution, the first drive assembly 300 may include the aforementioned first motor 310, first mounting base 320, first lead screw 330, first slider 340, and first guide rod 350. Based on the aforementioned configuration, when the first motor 310 is running, it can drive the first lead screw 330 to rotate relative to the first mounting base 320, thereby causing the first slider 340 and the first guide rod 350 disposed on the first slider 340 to move along the axial direction of the first lead screw 330. This changes the relative position between the first guide rod 350 and the first mounting base 320, thereby adjusting the distance between the first connecting end 301 and the second connecting end 302. Furthermore, the lead screw drive has good self-locking properties, which helps to ensure the stability of the relative position between the first connecting end 301 and the second connecting end 302 when the first motor 310 stops running. This ensures the stable and reliable position of the processing platform 100, which is beneficial for the stable placement of the workpiece during processing and provides assurance for processing accuracy.
[0080] It is understood that the aforementioned second connecting end 302 can be directly hinged to the transition platform 500, or indirectly hinged to the transition platform 500. For example, as... Figure 3 As shown, the first drive assembly 300 may further include a hinge seat 360 and a push plate 370, wherein the hinge seat 360 is fixedly connected to the aforementioned second connection end 302, the push plate 370 is rotatably connected to the hinge seat 360, and the push plate 370 is fixedly disposed on the transition platform 500.
[0081] For example, the aforementioned first lead screw 330 can be a ball screw.
[0082] like Figure 3 As shown, in some feasible examples, the first drive assembly 300 may also include a first guide rail 380, which is disposed on the first mounting base 320 and extends along the axial direction of the first lead screw 330, and the first slider 340 slides in engagement with the first guide rail 380.
[0083] like Figure 3 As shown, in some feasible examples, the first drive assembly 300 may also include a first reducer 390, which is drively 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 further includes: a mounting platform 600 movably connected to a transition platform 500, the transition platform 500 being adapted to rotate relative to the mounting platform 600 about a first axis and / or a second axis; wherein a second drive assembly 400 is connected between the mounting platform 600 and the transition platform 500.
[0085] In this technical solution, the clamping device may further include the aforementioned mounting platform 600. Based on the aforementioned configuration, the clamping device can use the mounting platform 600 to support the second drive component 400 and the transition platform 500. Correspondingly, the second drive component 400 can drive the transition platform 500 to rotate around the first axis and / or the second axis, thereby causing the processing platform 100 to generate a rotation in the corresponding rotation direction. Thus, with the support of the mounting platform 600, the movement stability and installation reliability of the transition platform 500 and the processing platform 100 can be improved.
[0086] like Figure 1 As shown, in some examples, the mounting platform 600 includes: a third platform body 610; a first bearing 620 disposed on the third platform body 610; a second bearing 630 disposed on the transition platform 500; and a Hooke hinge 640 including a first pivot and a second pivot, the first pivot being rotatably disposed on the first bearing 620 and extending along a second axis, the second pivot being rotatably disposed on the second bearing 630 and extending along a third axis, and the first pivot being fixedly connected to the second pivot.
[0087] In this technical solution, the mounting platform 600 may include the aforementioned third platform body 610, first bearing 620, second bearing 630, and Hooke hinge 640. Based on the aforementioned configuration, the transition platform 500 can be movably connected to the third platform body 610 via a Hooke hinge composed of the first bearing 620, second bearing 630, and Hooke hinge 640, thereby improving the structural compactness of the clamping device while enabling the transition platform 500 to rotate around the aforementioned second axis and / or the aforementioned third axis.
[0088] It is understood that, based on the aforementioned configuration 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 is understandable that both ends of the first rotating shaft can be connected to a first bearing seat 620, and both ends of the second rotating shaft can be connected to a second bearing seat 630.
[0090] like Figure 1 As shown, in some feasible examples, the Hooke hinge 640 is also connected to the transition platform 500 via a second connecting flange 650, which can further improve the connection reliability between the Hooke hinge 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 connecting end 401 and a fourth connecting end 402. The third connecting end 401 is disposed on the mounting platform 600, and the fourth connecting end 402 is hinged to the transition platform 500. The distance between the third connecting end 401 and the fourth connecting end 402 is adjustable. Both the third connecting end 401 and the fourth connecting end 402 are arranged at intervals from the second 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 be different, thereby changing the angle between the transition platform 500 and the mounting platform 600, and realizing the drive of the transition platform 500, so that the transition platform 500 will generate a rotation around the second axis and / or the third axis, thereby driving the processing platform 100 to generate a rotation in the corresponding rotation direction, and realizing the flexible adjustment of the position and posture of the processing platform 100.
[0093] For example, when multiple second drive components 400 located at the same axial position along the second axis produce the same aforementioned distance change, and multiple second drive components 400 located at different axial positions along the second axis produce different aforementioned distance changes, the multiple drive components can jointly drive the transition platform 500 to rotate around the third axis; or, when multiple second drive components 400 located at the same axial position along the third axis produce the same aforementioned distance change, and multiple second drive components 400 located at different axial positions along the third axis produce different aforementioned distance changes, the multiple drive components can jointly drive the transition platform 500 to rotate around the second axis; or, when the aforementioned distance changes produced by the multiple second drive components 400 are different from each other, the multiple drive components can jointly drive the transition platform 500 to rotate, so that the rotation amount of the transition platform 500 during the aforementioned rotation process has a rotation component around the second axis and a rotation component around the third axis.
[0094] like Figure 2 and Figure 4As shown, in some examples, the second drive assembly 400 includes: a second motor 410; a second mounting base 420 having a third connecting end 401; and a lifting mechanism disposed on the second mounting base 420, the lifting mechanism having a fourth connecting end 402. The second motor 410 is used to drive the lifting mechanism to move in order to adjust the distance between the third connecting end 401 and the fourth connecting end 402.
[0095] In this technical solution, the second drive component 400 may include the aforementioned second motor 410, second mounting base 420 and lifting mechanism; based on the aforementioned configuration, the second motor 410 can drive the lifting mechanism to move during operation, so as to change the distance between the aforementioned fourth connecting end 402 and the aforementioned third connecting end 401, thereby driving the transition platform 500 to move relative to the mounting platform 600.
[0096] In some feasible examples, the lifting mechanism includes a second lead screw 430, a second slider 440, a third slider 450, a second guide rail 460, a third guide rail 470, and a second reducer 480. The second lead screw 430 is rotatably mounted to the second mounting base 420. The second reducer 480 is driveably connected between the second lead screw 430 and a second motor 410, allowing the second motor 410 to drive the second lead screw 430 to rotate via the second reducer 480. The second slider 440 is driveably connected to the second lead screw 430 and adapted to move axially along the second lead screw 430. The second guide rail 460 is mounted on the second mounting base 420 and slides with the second slider 440. The extension direction of the second guide rail 460 is parallel to that of the second lead screw 430. The axes are aligned. The third guide rail 470 is disposed on the second mounting base 420 and slides with the third slider 450. The extension direction of the third guide rail 470 is perpendicular to the extension direction of the second lead screw 430. Both the second slider 440 and the third slider 450 have guide slopes. The guide slope of the second slider 440 slides with the guide slope of the third slider 450. Thus, when the second slider 440 moves along the axis of the second lead screw 430, it can drive the third slider 450 to move along the second guide rail 460. The aforementioned fourth connecting end 402 is located on the third slider 450, that is, the third slider 450 is hinged to the transition platform 500. Therefore, when the third slider 450 moves, it can drive the transition platform 500 to move accordingly.
[0097] For example, the aforementioned second lead screw 430 can 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 for detecting motion information of the transition platform 500, thereby facilitating the control of the first drive component 300 and the second drive component 400 based on the aforementioned motion information in practical applications. For example, the aforementioned detection component 900 may include a laser detection sensor.
[0099] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some examples, the clamping assembly 200 includes: a first clamping part 210 disposed on the processing platform 100 and having a first clamping wall 201; and a second clamping part 220 disposed on the processing platform 100 and having a second clamping wall 202, wherein the second clamping wall 202 is arranged opposite to the first clamping wall 201 and the second clamping wall 202 can be close to or away from the first clamping wall 201; wherein both the first clamping wall 201 and the second clamping wall 202 are used to abut against the workpiece to be processed.
[0100] In this technical solution, the clamping assembly 200 may include the aforementioned first clamping part 210 and the aforementioned second clamping part 220; based on the aforementioned configuration, the clamping assembly 200 can clamp the workpiece to be processed using the relatively arranged first clamping wall 201 and second clamping wall 202, and can clamp or release the workpiece to be processed by adjusting the distance between the first clamping wall 201 and the second clamping wall 202.
[0101] For example, such as Figure 5 and Figure 6 As shown, the first clamping part 210 may include a first support base and a first pad 212 disposed on the first support base 211, the first pad 212 forming a first clamping wall 201; the second clamping part 220 may include a second support base 221, a third lead screw 222, a ball head mounting base 223, a clamping plate 224, a ball head pressure plate 225, a second guide rod 226, and a second pad 227, wherein the third lead screw 222 is rotatably disposed on the second support base 221, and one end of the third lead screw 222 forms a ball head, the ball head being connected to the ball head mounting base 223. The ball head pressure plate 225 is sleeved on the third lead screw 222 and located on the side of the ball head away from the ball head mounting seat 223. The ball head pressure plate 225 is fixedly connected to the ball head mounting seat 223. The clamping plate 224 is disposed on the ball head mounting seat 223. The second pad 227 is disposed on the side of the clamping plate 224 away from the ball head mounting seat 223. The second pad 227 forms a second clamping wall 202. The second guide rod 226 is slidably inserted through the second support 221 and one end is fixedly connected to the clamping plate 224. The second guide rod 226 is arranged parallel to the third lead screw 222.
