[0009] The clamping assembly includes: a support column and a pressure plate; the support column is provided in plurality and is fixedly connected to the base plate and evenly distributed along the outside of the blank; the pressure plate is arranged on the top of the support column and is pressed against the top of the blank.

[0010] The beneficial effect of adopting the above technical solution is that the side wall of the blank and the groove wall of the storage groove in the utility model are tightly attached to position the blank in the X-axis and Y-axis directions, and the clamping assembly can position the blank in the Z-axis direction. The positioning is convenient, and multiple workpieces can be processed at the same time, which can improve the processing efficiency of the workpieces.

[0011] Preferably, the clamping assembly further comprises a bolt, the bottom of which is connected to the base plate, and the top of which penetrates the clamping plate and is connected to a nut. The clamping plate can be limited by the bolt and the nut, so that the clamping plate can clamp the blank more stably.

[0012] Preferably, the base plate is provided with bolt holes at positions corresponding to the bolts for the bolts to be inserted in. The provision of the bolt holes makes the connection between the bolts and the base plate more stable.

[0013] Preferably, during a first processing step, a plurality of positioning holes are processed on the surface of the blank.

[0014] Preferably, during the second-order processing, the blank is turned upside down and then clamped, and a positioning pin is arranged in the positioning hole, and the positioning pin is connected to the bottom plate. The positioning pin can be angularly positioned, and the workpiece to be processed is accurately positioned during processing.

[0015] Preferably, during the second-order processing, the number of the clamping assemblies is the same as the number of the positioning holes, and the positions correspond one to one. During the second-order processing, the clamping assembly and the positioning pin simultaneously position a processed workpiece, so that the positioning of the processed workpiece is accurate, and the quality of the workpiece can be guaranteed.

[0016] Preferably, the number of the clamping assemblies selected for the first-order processing is less than the number of the clamping assemblies selected for the second-order processing.
