Referring to fig. 1-6, an embodiment of the present invention provides a buffer device for a cylinder rocker arm, referring to fig. 1, including revolving cylinder 1, rocker arm 4, connecting plate 5 and support frame 7, support frame 7 side fixed mounting has revolving cylinder 1, revolving cylinder 1's rotation axis fixedly connected with rocker arm 4, rocker arm 4 top fixedly connected with connecting plate 5, and connecting plate 5 bottom fixed mounting has actuating mechanism such as tongs etc..

The side of the rotary cylinder 1 is provided with an elastic sheet assembly 2, refer to fig. 3, the elastic sheet assembly 2 comprises a first elastic sheet 21 (deformation section) and a second elastic sheet 22 (installation section) perpendicular to the first elastic sheet 21, the first elastic sheet 21 and the second elastic sheet 22 are integrally formed, the first elastic sheet 21 is communicated with a plurality of first installation holes used for fixing the first elastic sheet 21 and fixedly connected with the shell of the rotary cylinder 1 through screws, the top end of the second elastic sheet 22 is communicated with a second installation hole used for fixing the first elastic block 3, and the first elastic block 3 is fixedly connected with the second elastic sheet 22 through bolts.

The first elastic block 3 (which is cylindrical) is arranged to match the rocker arm 4, i.e. the diameter of the first elastic block 3 is larger than the width of a single side plate of the rocker arm 4. referring to fig. 3, when the rocker arm 4 is opened, it will first contact the first elastic block 3.

The supporting block 6 is arranged at the top of the supporting frame 7, the supporting block 6 is I-shaped, a countersunk hole is formed in the center of the top of the supporting block 6, and the supporting block 6 is fixedly connected with the supporting frame 7 through a countersunk screw. The top of the supporting block 6 is clamped with a cushion block 8, the top of the cushion block 8 is provided with an elastic pad 9 through a plurality of countersunk head screws, and referring to fig. 2, when the rocker arm 4 is closed, the rocker arm will be firstly contacted with the cushion block 8 (the elastic pad 9).

Referring to fig. 5 and 6, the top of the cushion block 8 is provided with a mounting hole 13, the mounting hole 13 is communicated with the bottom surface of the cushion block 8, a bottom plate 17 is arranged in the mounting hole 13, an external thread 19 is arranged on the outer side of the bottom plate 17, an internal thread 18 is arranged at the bottom of the inner wall of the mounting hole 13, and a hexagonal groove is further arranged at the bottom of the bottom plate 17, so that the bottom plate 17 can be screwed into the mounting hole 13 from the bottom through a tool.

The welding of bottom plate 17 top has fixed cover 15, fixed cover 15 top sliding connection has sliding sleeve 14, can follow fixed cover 15 bottom and pack into during sliding sleeve 14 assembly, the welding of sliding sleeve 14 top has spliced pole 12, the welding of spliced pole 12 top has sliding plate 10, there is second elastic block 11 (hemisphere) at sliding plate 10 top through the screw mounting, be provided with spring 16 in the sliding sleeve 14, spring 16 both ends link firmly with sliding sleeve 14 and bottom plate 17 respectively, spliced pole 12, mounting hole 13, sliding sleeve 14, fixed cover 15 and the 16 central axis collineations of spring.
