Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-5, the cylinder barrel structure of the high-speed buffer oil cylinder comprises a cylinder barrel body 1 and cylinder barrel deceleration parts 2 arranged at the front end and the rear end of the cylinder barrel body 1, the cylinder barrel deceleration parts 2 are respectively connected with a sealing tube body 3, a piston rod 4 is arranged in a piston cavity formed by the cylinder barrel body 1 and the cylinder barrel deceleration parts 2, one end of the piston rod 4 is provided with an oil pushing part 41, the piston rod 4 drives the oil pushing part 41 to reciprocate in the cylinder barrel, the thickness of the cylinder barrel deceleration part 2 is smaller than that of the cylinder barrel body 1, the cylinder barrel deceleration part 2 is provided with a plurality of damping holes 21, liquid oil reciprocates between the piston cavity and the sealing tube body 3 through the damping holes 21, the thickness of the cylinder barrel deceleration part 2 is smaller than that of the cylinder barrel body 1, the depth of the damping holes 21 is reduced, the pressure generated on the damping holes 21 when the liquid oil passes through the damping holes, meanwhile, the clearance between the cylinder barrel speed reducing part 2 and the sealing pipe body 3 is enlarged, the oil storage capacity is improved, and the braking effect is improved;
when the piston rod 4 moves back and forth, the number of the damping holes 21 participating in oil discharge on the cylinder barrel speed reducing part 2 on one side of the moving direction gradually decreases along with the movement of the piston rod 4, so that the oil pressure in the cylinder barrel speed reducing part 2 is increased, the effect of braking and speed reducing is achieved on the oil pushing part 41, the cylinder barrel can not only play a role in guiding and positioning the movement of the piston rod 4, but also play a role in smoothly braking and buffering in the back and forth movement process of the piston rod 4.
