[0055] Optionally, the clamping assembly 500 further comprises a threaded rod 530, an axis of the threaded rod 530 is parallel to the first direction X, the threaded rod 530 is provided with a plurality of first clamping blocks 520 one-to-one corresponding, one end of the threaded rod 530 is rotationally connected with the first clamping block 520, and the other end is threadedly connected with the back plate 510. By rotating the threaded rod 530, the threaded rod 530 rotates relative to the first clamping block 520, and moves relative to the back plate 510 along the first direction X, so as to realize clamping or releasing of the back plate 510 and the first clamping block 520.

[0056] Further, the first clamping block 520 is provided with a bearing, an outer ring of the bearing is fixed with the first clamping block 520, and the threaded rod 530 is fixedly inserted into an inner hole of an inner ring of the bearing.

[0057] Further, the clamping assembly 500 comprises a first driving member for driving the threaded rod 530 to rotate.

[0058] Optionally, the clamping assembly 500 further comprises a second clamping block 540, the second clamping block 540 is fixed to the back plate 510, the workpiece is clamped between the second clamping block 540 and the first clamping block 520, and the workpiece is spaced apart from the back plate 510.

It can be understood that the higher the sharpness of the drill bit, the smaller the force of the hole making tool 1 acting on the workpiece along the first direction X when processing the same specification hole, and with the accumulation of processing time, the sharpness of the drill bit gradually decreases, and the required force F gradually increases; when F>F 阈 , it indicates that the sharpness of the drill bit of the hole making tool 1 is too low, not only needs a large force F as compensation, but also is difficult to maintain the processing precision, at this time the control unit feeds back to the user that the hole making tool 1 needs to be replaced.

[0064] Optionally, the hole making tool further comprises a collection box 700, the collection box 700 is located below the clamping assembly 500, the opening of the collection box 700 faces upward, and is used to obtain the waste falling from the workpiece.

In this way, the collection box 700 is placed.

[0066] Further, the base 100 further comprises a second driving member for driving the collection box 700 to slide on the second X-direction guide rail. For example, the base 100 is provided with the second driving member on one side of the first direction X. The second driving member is a telescopic rod structure, such as a pneumatic cylinder structure or an electric rod structure. The telescopic rod structure can be telescoped along the first direction X. The telescopic end of the telescopic rod structure is detachably connected with the collection box 700. The collection box 700 is placed on the second X-direction guide rail. The collection box 700 is connected with the telescopic rod structure. The telescopic rod structure can push the collection box 700 to the lower side of the clamping assembly 500. When it is needed to empty the collection box 700, the telescopic rod structure can pull the collection box 700 back to the original position.

[0067] Further, the displacement assembly 200, the punching tool 1 and the second driving member are in communication connection with the control unit. The user can input basic parameters of the current operation to the control unit, such as the material of the workpiece, the three-dimensional size of the workpiece, the number of punching holes, the diameter and depth of the punching holes, etc. Based on the above parameters, the control unit can estimate the waste generated by the current operation. For example, the waste condition is the volume of the generated waste v n , the subscript n is the number of operations, v 总 =∑v n , when v 总 <kV, k is a proportional coefficient, k<1 is satisfied, and V is the volume of the collection box 700, it is considered that the collection box 700 can still load the waste generated by the current operation, and the operation can be started. If v 总 ≥kV, it is considered that the collection box 700 cannot load the waste generated by the current operation, and the control unit sends a signal to the user to empty the collection box 700. The second driving member can also control the collection box 700 to be pushed to the original position, so as to facilitate the user to empty the collection box 700. Further, the base 100 is provided with a trigger sensor for judging whether the collection box 700 is placed under the clamping assembly 500. If it is judged that the collection box 700 is placed under the clamping assembly 500, the punching tool 1 starts to punch the workpiece. Otherwise, a signal is fed back to the user.

[0068] It can be understood that when the waste naturally falls and accumulates, space gaps will be generated between the waste, so k<1 is satisfied.

[0069] As shown in FIG. Figure 4 , the use mode is roughly as follows:

[0070] S100, obtaining basic parameters of the current operation;

[0071] S210, outputting a punching template 320 required by the current operation and a drill bit model of the punching tool 1;

[0072] S221, estimating the waste condition generated by the current operation, i.e., v n ;

[0073] S222, determining whether v is satisfied 总 S310 if satisfied, S710 if not satisfied;
