[0024] It should be noted here that: by adjusting the setting of the component, under the action of the driving component and the moving component, while ensuring the convenience of fixing the plate and the repeated positioning accuracy during the continuous processing of large quantities of plates, it is convenient to effectively distribute the clamping force of the clamping plate 103 according to the size of the plate, thereby reducing the insufficient clamping force or stress concentration caused by the mismatch between the clamping force distribution and the size of the plate, thereby further reducing the risk of displacement, vibration or deformation of the plate during the processing, thereby improving the accuracy of plate clamping.

[0026] It should be noted here that: by setting the guide component, a guiding and limiting function is provided for the movement of the sliding plate 202.

[0027] See also Figure 2 and Figure 3 The driving assembly shown in the figure includes two driving plates 401 fixedly connected to the inner wall of the adjustment hole 201, the two driving plates 401 are rotatably connected to the double-headed threaded rod 402, the two sliding plates 202 are respectively threadedly connected to the side walls of the double-headed threaded rod 402, the length of the double-headed threaded rod 402 is less than the length of the clamping plate 103, and the clamping plate 103 is provided with a rotating assembly for rotating the double-headed threaded rod 402;

[0028] It should be noted here that: by setting the driving component, it is convenient to drive the two adjustment plates 203 to move closer to or away from each other.

[0030] It should be noted here that: by setting the rotating assembly, it is convenient to drive the double-headed threaded rod 402 to rotate.

[0031] Working principle: when fixing the plate, first place the plate on the workbench 102, and then adjust the distribution of the pressing force between the two clamping plates 103 and the plate according to the size of the plate. During the adjustment process, the rocker 504 is rotated to drive the rotating rod 501 to rotate. During the rotation of the rotating rod 501, the first bevel gear 502 is driven to rotate. Under the mutual meshing transmission action of the first bevel gear 502 and the second bevel gear 503, the double-headed threaded rod 402 is driven to rotate, thereby utilizing the thread meshing transmission action of the two sliding plates 202 and the double-headed threaded rod 402 and the guiding action of the guide assembly to drive the two adjustment plates 203 to move closer to or away from each other;

[0032] When the two adjustment plates 203 are moved to the appropriate position, the movement of the two sliding plates 202 is stopped, and then the moving assembly is used to drive the two clamping plates 103 to move closer to the plate. When the clamping plates 103 are against the side walls of the plate, the two adjustment plates 203 will simultaneously be against the side walls of the plate, thereby increasing the contact area with the plate under the pressing action of the two adjustment plates 203, effectively distributing the pressing force of the clamping plates 103, reducing insufficient clamping force or stress concentration caused by the mismatch between the pressing force distribution and the plate size, thereby further reducing the risk of displacement, vibration or deformation of the plate during processing and improving the accuracy of plate clamping.
