[0028] During this clamping process, the user first controls the start cylinder 5 so that the piston of the cylinder 5 starts to move. This action directly drives the first clamping plate 6 to move forward, thereby starting the operation of the entire clamping system. The movement of the first clamping plate 6 drives the first limiting plate 9 and the first silicone pad 7 to move together, so that the first silicone pad 7 moves accurately to the middle position of the front and rear sides of the workpiece. At the same time, the movement of the first limiting plate 9 causes the connecting plate 10 to move accordingly. The design of the connecting plate 10 enables it to effectively transmit force while maintaining stability. This action further drives the clamping block 11 to approach the workpiece. The clamping block 11 promotes the movement of the second silicone pad 12 through its movement, so that it can accurately Positioned at the left and right positions on the front and back sides of the workpiece, through this series of coordinated actions, this workpiece clamping equipment for CNC boring and milling machines realizes the multi-sided clamping function of the workpiece. Multi-sided clamping not only improves the stability of the workpiece, but also greatly enhances the safety during the processing. The first silicone pad 7 and the second silicone pad 12 both play an important role in the clamping process. Their flexible characteristics make the clamping force evenly distributed, effectively preventing the displacement and vibration of the workpiece during the processing. In addition, the use of multiple silicone pads also plays a role in protecting the workpiece to prevent wear or damage at the clamping point. This design takes into account the fineness and integrity of the workpiece surface, ensuring high-quality processing results.

[0029] Reference Figure 1-Figure 3 A number of slide grooves 2 are evenly opened on the upper part of the base 1, and sliders 3 are slidably connected to the left and right sides of the slide grooves 2.

[0030] During operation, the user first controls and starts the electric telescopic rod 17 to start running. The movement of the electric telescopic rod 17 directly drives the second clamping plate 18 to move through the mechanical structure. This action is the starting link of the entire clamping process. As the second clamping plate 18 moves, the clamping plate begins to drive the third silicone pad 20 to move to both sides of the workpiece. The third silicone pad 20 is designed to provide uniform contact pressure to ensure that the workpiece is not easy to slide or shift during the clamping process, thereby enhancing the stability of the clamping. At the same time, the movement of the second clamping plate 18 also guides the clamping block 11 to slide on the outside of the connecting plate 10 This design ensures that the clamping block 11 can flexibly adjust its position to adapt to workpieces of different sizes and shapes. The movement of the clamping block 11 further drives the adjustment of the second silicone pad 12, so that it can accurately contact the workpiece. The flexibility and adaptability of the second silicone pad 12 ensure the safety of clamping and reduce the risk of damage to the workpiece surface. Through the above series of coordinated movements, this workpiece clamping device for controlled boring and milling machines realizes the adaptability to different types of workpieces. Whether it is a large workpiece or a small component, the device can effectively adjust the clamping method to improve the efficiency and accuracy of clamping.

[0031] Working principle: When it is necessary to clamp the workpiece for boring and milling of the CNC boring and milling machine, the workpiece is placed on the upper part of the base 1, and the electric telescopic rod 17 is controlled to start so that the electric telescopic rod 17 is operated to drive the second clamping plate 18 to move, so that the second clamping plate 18 drives the third silicone pad 20 to move to both sides of the workpiece, and at the same time, the second clamping plate 18 drives the clamping block 11 to slide on the outside of the connecting plate 10, and the clamping block 11 drives the second silicone pad 12 to move, thereby realizing that the workpiece clamping device for the CNC boring and milling machine can be applied to different types of workpieces, improving the practicality of the clamping device, and then controlling the cylinder 5 to start so that the cylinder 5 drives the second clamping plate 11 to move.
