[0023] Embodiment 1: This embodiment is intended to help solve the problem that the existing knife-beating cylinder may not be able to flexibly adjust the stroke, resulting in unsatisfactory efficiency and accuracy in specific processing tasks. Please refer to Figure 1 - Figure 4 A stroke-adjustable knife-beating cylinder comprises an oil cylinder 100, an air cylinder 200 and a knife-beating head 300. The oil cylinder 100 is arranged at the bottom side of the air cylinder 200. A mounting plate 400 is fixedly mounted on the upper side of the oil cylinder 100. The air cylinder 200 is mounted on the mounting plate 400. A piston rod 210 is arranged in the air cylinder 200. An oil rod 110 is movably inserted in the oil cylinder 100. A movable rod 120 is movably inserted in the oil rod 110. The bottom of the mounting plate 400 is inserted into the oil cylinder 100. The top of the mounting plate 400 is inserted into the bottom of the air cylinder 200. A sealing plate 130 is installed at the bottom of the oil cylinder 100. A through hole 131 is opened in the sealing plate 130. A knife-beating head 300 is installed at the bottom end of the oil rod 110. The movable rod 120 is connected to the knife-beating head 300 through the through hole 131. An adjusting component 500 for controlling the oil rod 110 is arranged on the side of the oil cylinder 100.

[0024] The adjustment assembly 500 includes a fixed block 510 installed at the side of the oil cylinder 100, an adjustment cavity 511 is provided in the fixed block 510, an adjustment rod 520 is inserted in the adjustment cavity 511, a stopper 521 is installed at the bottom of the adjustment rod 520, an adjustment plate 530 is installed at the bottom of the stopper 521, and the adjustment plate 530 is connected to the side wall of the oil cylinder 100. An adjustment slot 540 is provided in the oil cylinder 100, and the adjustment plate 530 is movably inserted in the adjustment slot 540. The adjustment plate 530 is connected to the oil rod 110 through the adjustment plate 530. Threaded holes 541 are provided in the adjustment plate 530 and the oil rod 110, and a fixing screw 542 is inserted in the threaded hole 541.

[0025] An external threaded ring 522 is provided on the outside of the adjusting rod 520, and an internal threaded ring 512 is provided in the adjusting cavity 511, and the internal threaded ring 512 is threadedly matched with the external threaded ring 522. A control button 550 for controlling the adjusting rod 520 is fixedly installed on the top of the adjusting rod 520, and the control button 550 is located on the upper side of the external threaded ring 522. A groove 560 is provided in the fixing block 510, and the groove 560 is communicated with the adjusting cavity 511, and the control button 550 is partially inserted in the groove 560.

[0026] Working principle: Install the cutting cylinder on the machine tool, and ensure that the mounting plate 400 at the bottom of the oil cylinder 100 is in close contact with the machine tool and fixed. This step ensures the stability and safety of the cutting cylinder during operation. According to the specific processing requirements, select a suitable tool and install it on the cutting head 300. The cutting head 300 is usually fixed to the cutting cylinder through a fixing mechanism at the bottom of the oil rod 110, which may be a threaded connection or other forms.

[0027] The control knob 550 is used to adjust the position of the adjustment rod 520 to control the telescopic stroke of the oil rod 110. The operator can rotate the control knob 550 to move the control knob 550 portion on the external thread ring 522, thereby changing the position of the adjustment rod 520. This design allows the stroke of the cutter head 300 to be accurately adjusted to meet the processing requirements of different workpieces and the size of the tool. After the adjustment is completed, the staff will conduct a test to ensure that the position and stroke of the cutter head 300 meet the processing requirements.

[0028] In this embodiment: by adjusting the rod 520 and the related threaded mechanism, the operator can accurately control the telescopic stroke of the oil rod 110 to ensure that the position and movement of the cutting head 300 meet the requirements of a specific processing task, thereby improving the positioning accuracy and processing quality of the tool during the processing. At the same time, due to the design of the adjustment system, the cutting cylinder can quickly and flexibly adapt to the processing requirements of workpieces of different sizes and shapes. The operator only needs to adjust the stroke by rotating the control button 550 without replacing the entire tool, thereby saving adjustment time and improving production efficiency.

[0029] Embodiment 2: This embodiment is intended to promote the solution of the problem that the sealing disc 130 and the through hole 131 do not fully solve the control and leakage of the lubricating oil flow, which may cause the pressure loss or instability of the hydraulic system. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Figure 4 .

[0030] A telescopic rod 570 is arranged in the adjustment chamber 511, and the telescopic rod 570 is arranged on the top of the control button 550.
