Embodiment 1

[0032] see figure 1 and figure 2 , a cushioning cylinder device according to the present invention includes a cylinder body 01, and the cylinder body 01 includes a first through hole 011, a front end cover 012, a piston rod 013, a piston body 014, a cylinder barrel 015, a rear end cover 016 and a first through hole 011. Two through holes 017, the cylinder barrel 015 is set between the front end cover 012 and the rear end cover 016, the piston body 014 is slidingly connected to the inner cavity of the cylinder barrel 015, and the piston rod 013 is installed on the left end of the piston body 014; the first through hole 011 and the second through hole The two through holes 017 are opened at the central positions of the tops of the front end cover 012 and the rear end cover 016 respectively, and the front end cover 012 and the rear end cover 016 are provided with a first shock absorbing mechanism 02 and a second shock absorbing mechanism 03 on the sides close to each other.

Embodiment 2

[0034] see figure 1 and Figure 4 , the left and right sides of the piston body 014 close to the edge are equipped with buffer washers 06 through the fixing bolts 07, and the piston rod 013 is fixedly connected to the fixing bolts 07 on the left side of the piston body 014. This structure is set so that the two ends of the piston body 014 can be Receive preliminary cushioning protection to prevent direct damage to the piston body 014; the front view of the first through hole 011 and the second through hole 017 are both L-shaped and communicate with the inner cavity of the cylinder 015, the first through hole 011 and the second through hole 017 The connection between the second through hole 017 and the cylinder 015 extends outwards with an adapter groove. The diameter of the adapter groove is larger than the diameter of the fixing bolts 07 on both sides of the piston body 014. This structure allows the piston body 014 to move left and right When the fixed bolts 07 at both ends...

Embodiment 3

[0036] see figure 1 , 3 and Figure 5, the top ends of the first through hole 011 and the second through hole 017 are fixedly connected with the butt joint 04, and the front view of the two butt joints 04 are both T-shaped and communicate with the inner cavity of the first through hole 011 and the second through hole 017 respectively , the structure is set so that the first through hole 011 and the second through hole 017 can be better connected with the external inflation mechanism, so as to facilitate the control of the movement of the piston body 014; the second shock absorbing mechanism 03 includes a shock absorbing spring 031, The second card slot 032 and the second connecting rod 033, the second card slot 032 is located on the opposite side of the front end cover 012 and the rear end cover 016 and near the edge of the first through hole 011 and the second through hole 017 and is opened around the ring equidistantly. The second connecting rod 033 is slidably engaged in ...

Abstract

The invention relates to the technical field of air cylinders, and particularly discloses an air cylinder device with a cushioning function, the air cylinder device comprises an air cylinder body, the air cylinder body comprises a first through hole, a front end cover, a piston rod, a piston body, a cylinder barrel, a rear end cover and a second through hole, the cylinder barrel is arranged between the front end cover and the rear end cover, and the piston body is slidably connected to an inner cavity of the cylinder barrel; the piston rod is mounted at the left end of the piston body; according to the invention, the arranged first cushioning mechanism is matched with the cushioning gasket, so that the impact force can be effectively reduced when the piston body moves left and right, the impact force on the piston body and the cushioning gasket is reduced, and meanwhile, the arranged second cushioning mechanism is utilized to further improve the cushioning effect on the basis of the first cushioning mechanism; the cushioning effect is better, the service life of the piston body and the service life of the cushioning gasket are effectively prolonged, and the problems that a cushioning structure of a traditional air cylinder is simple and crude, and the cushioning effect is poor are solved.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a cylinder device with cushioning. Background technique [0002] Air converts heat energy into mechanical energy through expansion in the engine cylinder; gas is compressed by the piston in the compressor cylinder to increase the pressure, and the casing of the turbine, rotary piston engine, etc. is usually also called "cylinder". The application fields of the cylinder: printing, automation control, robot and so on. [0003] At present, when most of the cylinder devices are in use, the internal piston will move left and right under the push of air pressure, so as to drive the piston rod to move and realize the function of the cylinder. However, when the piston moves left and right, it is limited by the length of the cylinder body. The distance of its left and right movement is also limited. When the piston moves to the far left and right every time, it will be pressed and coll...
