Abstract
The invention discloses an adjustable stroke type buffer plunger cylinder, which comprises a plunger (1), a screw (3), a dustproof ring (4), a cover (5), a fixing ring (6), an O-shaped ring (8), a hole seal (9), a tube (10) and a spring (11). A cylindrical head at one end of the screw (3) is connected onto the plunger (1) through a bolt (2), the other end of the screw (3) penetrates through the fixing ring (6), the plunger (1) and the spring (11) are arranged on the inner hole of the hole seal (9), the dustproof ring (4) and the O-shaped ring (8) are respectively arranged in grooves of the cover (5) and the plunger (1), the cover (5) is screwed on threads of the hole seal (9) to press the fixing ring (6), and the tube (10) is sleeved on the spring (11). The buffer structure of the buffer plunger cylinder is changed into plunger buffering, and the processing accuracy and installation accuracy are high.
Description
Technical field
The present invention 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.
Summary of the invention
The purpose of this invention is to provide a kind of range-adjustable band bumper post plug cylinder.
The present invention 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 present invention 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 present invention 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.
