[0002] When processing threaded holes on the surface of a workpiece, three processes are generally required: drilling, reaming and tapping. When processing smooth holes, two processes are generally required: drilling and reaming. If these processes are processed separately on equipment that can perform these processes, multiple clamping is required, which is inconvenient. As a result, the processing accuracy of the threaded holes / clear holes of each workpiece is low, which easily causes large center deviations during reaming, opening and tapping. With the application of integrated drilling and tapping machines, the efficiency and accuracy of drilling threaded holes on the surface of workpieces can be effectively improved.

[0003] Before drilling and tapping the workpiece, it is necessary to transfer the workpiece. During this process, the workpiece needs to be taken from the surface of the conveyor belt and lowered to the punching station. This step requires the use of a clamp to clamp and fix the workpiece. Some clamps are rigid when clamping the workpiece, so that the surface of the workpiece may be deformed and damaged due to the rigid contact between the clamp and the workpiece. Therefore, an elastic clamping discharge arm for a drilling and tapping machine is needed, which can elastically clamp the workpiece through the elastic clamp, thereby improving the integrity of the workpiece's own surface during transportation.
