Description
Technical field
The utility model relates to the big seat of a kind of full-automatic oil pressure front upper stretching machine oil cylinder.
Background technique
The big seat of existing oil pressure front upper stretching machine oil cylinder, in the process of using, transfer the throttling plug screw of buffering to limit oily bypass amount, it is useful working when the piston rod breeze way enters buffer cavity, when back delivery piston bar moved, the oil mass that acts on piston rod breeze way end face was far longer than throttling bypass amount.Can unexpected increase at this moment be harmful at the moment stress surface that goes out breeze way.Often show: machine vibration is bigger, and big flap plate motion is unstable, speed waits shortcoming more slowly.
Summary of the invention
At the shortcoming of the big seat of existing oil pressure front upper stretching machine oil cylinder, the utility model provides the big seat of a kind of novel full-automatic oil pressure front upper stretching machine oil cylinder.
To achieve these goals, the measure taked of the utility model:
The big seat of full-automatic oil pressure front upper stretching machine oil cylinder comprises axle sleeve, protecgulum, bonnet, piston rod, and described protecgulum front end is connected with sealing gland by screw, is provided with seal ring between sealing gland and protecgulum front end groove; Axle sleeve is set in the sealing gland; Be provided with piston rod in the axle sleeve; Piston rod passes axle sleeve, protecgulum, cushion collar, oil cylinder, and the piston rod rear end is arranged in the buffering trepanning; Be provided with cushion collar, " O " type circle in the preceding cover back-end groove, and be tightly connected by " O " type circle, the cushion collar that is provided with in oil cylinder and the bonnet front end groove; The piston rod rear end is disposed with " O " type circle, back-up ring, shellfish filler ring; Back-up ring, " O " type circle, protecgulum; Bonnet is connected with joint, and bolt is connected with protecgulum by bonnet.
Described cushion collar is provided with 6 holes, and is provided with the polymorphic structure in arc groove and hole.
Be provided with steel ball in the hole on the described cushion collar.
Before hole on the described cushion collar and the piston rod behind breeze way, the piston rod cooperating between the breeze way diameter be Spielpassung.
The beneficial effects of the utility model: reduce machine vibration, make and improve movement velocity by big flap plate motion stabilization; Simple in structure, cost is low.

Embodiment:
The big seat of full-automatic oil pressure front upper stretching machine oil cylinder, as Fig. 1, Fig. 2, shown in Figure 3, comprise axle sleeve 1, protecgulum 5, bonnet 9, piston rod 12, described protecgulum 5 front ends are connected with sealing gland 3 by screw 2, are provided with seal ring 4 between sealing gland 3 and protecgulum 5 front end grooves; Axle sleeve 1 is set in the sealing gland 3; Be provided with piston rod 12 in the axle sleeve 1; Piston rod 12 passes axle sleeve 1, protecgulum 5, cushion collar 6, oil cylinder 11, and piston rod 12 rear ends are arranged in cushion collar 6 holes; Be provided with cushion collar 6, " O " type circle 8 in the protecgulum 5 rear end grooves, and be tightly connected by interior " O " type circle 8, the cushion collar 6 that is provided with of oil cylinder 11 and bonnet 9 front end grooves; Piston rod 12 rear ends are disposed with " O " type circle 13, back-up ring 14, shellfish filler ring 15; Back-up ring 14, " O " type circle 13, protecgulum 5; Bonnet 9 is connected with joint 16, and bolt 10 is connected with protecgulum 5 by bonnet 9.Be provided with steel ball 7 in the hole 19 on the cushion collar 6.As Fig. 4, Fig. 5, shown in Figure 6, hole 19 is used to adorn steel ball 7, hole 22 is used for logical oil and sealing, hole 21 is used for logical oil and causes oil pressure poor, hole 29 by-pass flow micropores are used for stable buffering and hole 23 communicates, it is smooth logical that hole 20 diameters can ensure that less than the diameter of steel ball 7 steel ball 7 opens when jumping oil, and arc groove 31 is used for guaranteeing to start moment oil pressure acting surface, and hole 30 diameters become Spielpassung with piston rod front and back breeze way 17,18 external diameters.As shown in Figure 7, the position of reflection big seat oil cylinder on frame.In the real work, bonnet joint 16 fuel feeding, steel ball 7 opens jumping, oil pressure acts on both ends of the surface simultaneously, piston rod 12 actions, big flap plate moves downward, when the preceding breeze way of piston rod 12 enters the hole 30 of cushion collar 6, pressure reduction makes the steel balls 7 in the hole on the cushion collar 6 19 press 22 hole end surfaces, oil can only be got back to fuel tank from micro-hole on the cushion collar 6 29 and matching gap, before piston rod, form a pressure chamber between the inwall of breeze way 17 peripheries and end face and oil cylinder 11, reduce the impact force of piston rod 12 and cushion collar 6 end faces; Principle is the same during protecgulum joint 16 fuel feeding.Also comprise big flap plate 24 among Fig. 7, big seat worktable 25, big seat slide plate 26, big seat oil cylinder 27 and frame 28.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
