Abstract
The utility model relates to a high-speed air cylinder. Due to the fact that a high-speed air cylinder seal is made of materials such as rubber, the high-speed air cylinder seal is prone to being abraded under the high-speed movement, if the high-speed air cylinder seal is used at the frequency of 10 times per second, the service life of the high-speed air cylinder seal is normally about 10-million times, and when the high-speed air cylinder continuously operates for 4 hours every day, the high-speed air cylinder seal will lose efficacy after the high-speed air cylinder operates for 11 days. The high-speed air cylinder comprises a cylinder barrel and a piston rod, and an end cover is arranged at the front end of the cylinder barrel. The high-speed air cylinder is characterized in that a pneumatic muscle tendon device is arranged in the cylinder barrel and comprises an air inlet end and a fixed end, the fixed end of the pneumatic muscle tendon device is sleeved with a spring and connected with the piston rod, the air inlet end of the pneumatic muscle tendon device penetrates through the end cover to be extended out of the cylinder barrel, and the air inlet end of the pneumatic muscle tendon device is provided with a first rapid connector. According to the high-speed air cylinder, the pneumatic muscle tendon device is used as a movement element, the problem that in an existing structure, the air cylinder is scrapped due to abrasions of the seal is solved, the high-speed movement of the air cylinder is guaranteed, meanwhile, the service life of the air cylinder is prolonged, and the structure is simple.
Description
Technical field
The utility model relates to a kind of cylinder, relates in particular to a kind of high-speed cylinder.
Background technique
Current known high-speed cylinder, is comprised of low friction cylinder barrel, end cap, low-friction piston, piston rod and low drag seal.Because the material making such as rubber are used in high-speed cylinder sealing, easily wearing and tearing under high-speed motion, if used under the frequency of 10 times/second, its working life is conventionally 1,000 ten thousand left and right, according to the 24 hours every days of operation continuously, can move 11 days, losing efficacy just appears in Sealing.
