Embodiment Construction
[0032] Below, in conjunction with the accompanying drawings, preferred embodiments of the present invention are given and described in detail, so that the functions and features of the present invention can be better understood.
[0033] Figure 2-11 One embodiment of the digital cylinder of the present invention is shown. As shown in the figure, the digital air cylinder of the present invention includes a first cylinder 21 with a closed bottom end, a first piston rod 22 extending into the first cylinder 21 at one end, and a first piston rod 22 fixed on the aforementioned one end of the first piston rod 22. A piston 23 and a positioning seat 24 with a central cavity, wherein one end of the valve core 31 of the valve body 3 is fixed in the cavity of the positioning seat 24 . Besides, the present invention also adds a second cylinder 28 , a second piston rod 29 and a second piston 210 .
[0034] Wherein, the second cylinder 28 is fixedly connected between the first cylinder 21...

The invention provides a digital air cylinder which comprises a first cylinder barrel, a first piston rod, a first piston and a positioning base and further comprises a second cylinder barrel, a second piston rod and a second piston. The second cylinder barrel is fixedly connected between the first cylinder barrel and the positioning base, a step hole is formed in the inner wall of the second cylinder barrel, and the smallest diameter portion of the step hole is close to the first cylinder barrel. The second piston rod is coaxially and fixedly connected between the first piston rod and a valve element. In addition, the digital air cylinder comprises a small diameter section and a large diameter section, and the outer wall of the large diameter section tightly attaches to the inner wall of the positioning base. The small diameter section of the second piston rod is sleeved with the second piston. A first air cavity is formed between the first piston and the bottom end of the first cylinder barrel, a second air cavity is formed between the second cylinder barrel and the first piston, a third air cavity is formed between the second cylinder barrel and the second piston, and a fourth air cavity is formed between the second piston and the positioning base. The oil cylinder can be flexibly started or stopped by adding the second cylinder barrel, the second piston rod and the second piston, and noise is eliminated.
Description
technical field [0001] The invention relates to the field of cylinders, in particular to a digital cylinder. Background technique [0002] A cylinder is a pneumatic actuator. figure 1 It shows a typical air cylinder, which is used to drive the valve core 31' of the valve body 3' to move in the axial direction, which includes a cylinder tube 21' with a closed bottom end, and a piston rod 22' with one end extending into the cylinder tube 21' , the piston 23' fixed on the aforementioned one end of the piston rod 22' and the positioning seat 24' having a central cavity, the cylinder tube 21' and the positioning seat 24' together constitute the cylinder body, and the valve core 31' of the valve body 3' One end is fixed in the cavity of the positioning seat 24'. In addition, a centering spring 25' is provided between the inner wall of the positioning seat 24' and the valve core 31', and opening pads 27' are respectively provided on both sides of the centering spring 25', and the...
