The invention discloses a multi-functional integrated type
hydraulic cylinder. The multi-functional integrated type
hydraulic cylinder comprises a main cylinder
barrel, a main cylinder cover, a
barrel-shaped main cylinder
piston rod, a rapid cylinder guide sleeve, an isolating ring, a three-section card key and a main cylinder guide sleeve and is characterized in that: a first oil port, a second oil port and a third oil port are formed on the main cylinder
barrel; a fourth oil port and a sixth oil port are formed on the main cylinder cover; a positioning cylinder guide sleeve is matched with the inner wall of the left end part of the main cylinder barrel; the inner wall of the positioning cylinder guide sleeve is matched with the outer wall of the main cylinder guide sleeve; the left end part of a barrel-shaped rapid cylinder
piston rod is matched with the inner wall of the barrel-shaped main cylinder
piston rod; the right end of the barrel-shaped rapid cylinder
piston rod is connected with a
locknut in a matching way; a rapid
cylinder head is connected with the inner wall of the left end part of the barrel-shaped main cylinder
piston rod in a matching way; a low-pressure oil inlet
pipe is fixedly connected in the barrel-shaped rapid cylinder
piston rod; and the right end of the low-pressure oil inlet
pipe is a fifth oil port. The multi-functional integrated type
hydraulic cylinder has the advantages of compact structure, high circulating operation speed, high
working pressure, large thrust force of a working condition,
high power density and convenient installation.
