Abstract

The invention discloses a pressure feedback type air cylinder buffering device. The pressure feedback type air cylinder buffering device comprises a buffering end cover and a cylinder barrel fixedly installed at the front end of the buffering end cover, and a piston rod assembly is installed in a buffering cavity of the cylinder barrel; a valve core cavity communicating with a drainage channel in an end cover body is arranged inside the end cover body of the buffering end cover, and a buffering valve core is arranged inside the valve core cavity. When the pressure feedback type air cylinder buffering device carries out buffering, gas in the buffering cavity can flow to two branches, one branch sequentially passes through the buffering cavity and a normally-open drainage port and is finally guided to a plunger cavity, and the other branch sequentially passes through the buffering cavity, an upstream drainage hole, a small-triangle drainage channel, a large-triangle drainage channel and a downstream drainage hole and is finally guided to the plunger cavity. Through cooperation between the buffering valve core and a buffering plunger inside the buffering end cover, good buffering effect is realized.

Description

technical field [0001] The invention relates to a buffer cylinder structure, in particular to a pressure feedback type cylinder buffer device. Background technique [0002] At present, modern pneumatic technology is developing in the direction of high speed, but the problem of cushioning the collision between the piston and the end cover at the end of the stroke has always been an urgent problem to be solved in the high speed of the cylinder. At present, the buffering strategies of high-speed cylinders that are widely used are overflow buffering and needle valve buffering. Adjust cushioning. Contents of the invention [0003] In response to the above problems, the present invention researches and designs a pressure feedback type cylinder buffer device, which is used to solve the problem of the existing overflow type buffer and needle valve type buffer for the change of working conditions such as mass load, speed, and air supply pressure. Poor self-adaptive ability, unabl...
