By arranging a limit sleeve 72 and a pull rod 76, it is convenient to limit the moving position of the piston rod 81 to prevent the low gas pressure inside the cylinder 1 from causing displacement of the piston rod 81.

[0041] Furthermore, the above-mentioned dual-axis precision slide cylinder also includes:

[0042] like Figure 2 As shown, in the embodiment of the present application, the top cover assembly 3 includes a top shell 31, a first sealing ring 32 and a first sealing gasket 33.

[0052] like Figure 2 and Figure 3 As shown, in an embodiment of the present application, the piston assembly 8 includes a piston rod 81, a magnet 82, a second sealing ring 83, a filling layer 84 and a support plate 85. The piston rod 81 is arranged inside the cylinder 1, one end of the piston rod 81 is fixedly connected to the magnet 82, the outer wall of the magnet 82 is sleeved with the second sealing ring 83, the interior of the magnet 82 is arranged with a filling layer 84, a support plate 85 is fixedly connected between the magnets 82, and the outer wall of the piston rod 81 is arranged inside the third sealing ring 103 inside the connecting head 101 and inside the cleaning pad 105.

[0053] It should be noted that a magnet 82 and a second sealing ring 83 are provided at one end of the piston rod 81, which can reduce the friction between the piston and the cylinder liner. The magnet 82 can be used in conjunction with the sealing ring on the cylinder liner to form an effective sealing structure on the piston.

[0055] It should be noted that by providing the slide assembly 4 on the outer wall of the piston rod 81 and the outer wall of the cylinder 1 , it is convenient to install various equipment.

[0056] It should be noted that the control method of the present application can be automatically controlled by a controller, and the control method of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field, and the present application is mainly used to protect mechanical structures, so the present application will no longer explain the control method and circuit connection in detail.

Figure 2As shown in the figure, a magnet 82 and a second sealing ring 83 are provided at one end of the piston rod 81. Due to the flexible connection between the second sealing ring 83 and the cylinder sleeve 1, the friction between the piston and the cylinder sleeve 1 can be reduced. The magnet 82 can be used in conjunction with the second sealing ring 83 on the cylinder sleeve. The magnet 82 absorbs the cylinder barrel 1 through magnetic force and squeezes the second sealing ring 83 to fit tightly inside the cylinder barrel 1, so that the piston and the cylinder barrel 1 form an effective sealing structure. This structure can not only prevent the leakage of gas and liquid, but also prevent dust and other debris from entering the interior, thereby maintaining the normal working state of the equipment. By arranging a limit rod 75 at the top of the support plate 85, when the piston rod 81 moves up and down, the limit rod 75 is driven to move up and down. The limiting sleeve 72 and the pull rod 76 are provided to facilitate limiting the moving position of the piston rod 81 to prevent the piston rod 81 from being displaced due to the low gas pressure inside the cylinder 1. The third sealing ring 103 is provided at the movable part of the piston rod 81, so that the piston rod 81 can be sealed when the piston rod 81 contracts. The cleaning pad 105 is provided to facilitate cleaning of the piston rod 81. The limiting cover 51 can be provided to disassemble and replace the cleaning pad 105 to prevent the surface of the piston rod 81 from absorbing dust and other impurities, which would reduce the sealing effect of the third sealing ring 103. The slide assembly 4 is provided on the outer wall of the piston rod 81 and the outer wall of the cylinder 1 to facilitate the installation of various equipment.
