Abstract
The utility model discloses a stroke-adjustable buffering plunger type cylinder comprising a plunger (1), a lead screw (3), a dust ring (4), a cover (5), a fixing ring (6), an O-shaped ring (8), a hole seal (9), a cylinder (10) and a spring (11), wherein a cylinder end at one end of the lead screw (3) is connected to the plunger (1) through a bolt (2), and the other end of the lead screw (3) passes through the fixing ring (6); the plunger (1) and the spring (11) are arranged in inner holes of the hole seal (9); the dust ring (4) and the O-shaped ring (8) are respectively arranged in troughs of the cover (5) and the plunger (1); the cover (5) is screwed on a screw thread of the hole seal (9) to tightly press the fixing ring (6); and the cylinder (10) is sleeved on the spring (11). The stroke-adjustable buffering plunger type cylinder provided by the utility model is changed from a buffering plunger type cylinder buffering structure into a plunger buffering structure and is high in machining and mounting precisions.
Description
Technical field
The utility model relates to a kind of range-adjustable band bumper post plug cylinder.
Background technique
Present plunger case does not have spacing and buffering mostly, have spacing be inner at oil cylinder, be nonadjustable.Band bumper post plug cylinder buffer structure is the plunger buffering now, and processing and installation precision are all very high.
The model utility content
The purpose of the utility model provides a kind of range-adjustable band bumper post plug cylinder.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of range-adjustable band bumper post plug cylinder; Comprise that plunger (1), screw mandrel (3), dust ring (4), lid (5), retaining ring (6), O type circle (8), hole are with sealing (9), tube (10) and spring (11); One end socket cap of said screw mandrel (3) is connected on the plunger (1) through bolt (2); The other end of screw mandrel (3) passes retaining ring (6); Plunger (1) and spring (11) are installed in the hole with sealing (9) endoporus; Dust ring (4) and O type circle (8) are installed in respectively in the groove of lid (5) and plunger (1), and lid (5) is screwed on the screw thread of hole with sealing (9) retaining ring (6) is compressed, and tube (10) is sleeved on the spring (11).
Said screw mandrel (3) is fixed on the retaining ring (6) through nut (7).
Said bolt (2) and screw mandrel (3) constitute position-limit mechanism.
Through the distance adjustment piston rod stroke of adjusting nut (7) with retaining ring (6).
A kind of range-adjustable band of the utility model bumper post plug cylinder becomes band bumper post plug cylinder buffer structure and is the plunger buffering, and processing and installation precision are all very high.
Description of drawings
Fig. 1 is the structural representation of a kind of range-adjustable band of the utility model bumper post plug cylinder.
Among the figure: 1, plunger; 2, bolt; 3, screw mandrel; 4, dust ring; 5, lid; 6, retaining ring; 7, nut; 8, O type circle; 9, the hole is with sealing; 10, tube; 11, spring.
Embodiment
As shown in Figure 1, range-adjustable band bumper post plug cylinder comprises that plunger 1, screw mandrel 3, dust ring 4, lid 5, retaining ring 6, O type circle 8, hole are with sealing 9, tube 10 and spring 11; One end socket cap of screw mandrel 3 is connected on the plunger 1 through bolt 2, and the other end of screw mandrel 3 passes retaining ring 6, and screw mandrel 3 is fixed on the retaining ring 6 through nut (7); Plunger 1 is installed in the hole with sealing 9 endoporus with spring 11, dust ring 4 and O type circle 8 be installed in respectively cover 5 with the groove of plunger 1 in, lid 5 is screwed in the hole and with sealing on 9 the screw thread retaining ring 6 is compressed; Tube 10 is sleeved on the spring 11; When piston rod reached certain position, nut 7 nuts and retaining ring 6 retaining rings were collided, and stoped piston rod to advance through bolt 2 and screw mandrel 3; Reach position-limiting action; Adjusting nut 7 just can be adjusted piston rod stroke and mounting distance with the distance of retaining ring 6, when piston rod is withdrawn, reaches the effect of buffering through the compression generation of the contained spring power opposite with piston motion.
Claims (4)
