Description
Technical field
The utility model relates to chain disassembling fixture field, is specifically related to a kind of chain provision for disengagement.
Background technology
Chain drive is mechanically operated a kind of important form.Driving chain generally adopts bushroller chain, is made up of inner plate, outer plate, sleeve and roller.Bearing pin and outer plate, sleeve and inner plate are all that interference is accompanied.Connected by outer plate between each chain link, when chain link bends and stretches, sleeve freely can rotate on bearing pin.When needs block chain, need outer plate bearing pin being extruded chain both sides.Under equipment long time running, there is the phenomenon of chain wear unavoidably, but the elongation of chain can be caused after chain wear and relax, thus affect the accuracy of chain drive cooperation, affect the normal work of plant equipment.Normally chain dismantling is blocked to repair, take off from chain nodal plate by chain rivet.Prior art dismounting chain normally transfers pad nut at chain, and then knock the pin on chain with hammer, pin is come off from chain, workman in operation, often makes hammer pound to hand because hammer skids when knocking pin.
There is the deficiency that efficiency is low, safety coefficient is low in prior art dismounting chain as can be seen here.
Utility model content
The technical problems to be solved in the utility model there is for prior art dismounting chain the deficiency that efficiency is low, safety coefficient is low to provide a kind of chain provision for disengagement, has chain removal efficiency high, the feature that safety coefficient is high.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: chain provision for disengagement comprises base, threaded rod and cam, and threaded rod is connected with whorl of base, and cam is positioned at below threaded rod; Described base comprises C type seat, riser and backing plate, and the upper end of riser is connected with C type seat, and the lower end of riser is connected with backing plate; C type seat comprises upper backup pad, side plate and base plate, and upper backup pad is parallel with base plate, and the upper end of side plate connects upper backup pad, the lower end connecting bottom board of side plate; Upper backup pad is provided with the tapped through hole matched with threaded rod, and base plate is provided with counterbore, and the axial line conllinear of the center line of counterbore and tapped through hole; Lining is provided with in counterbore; Described riser is provided with through hole, is provided with axle sleeve in through hole, is provided with turning cylinder in axle sleeve, axle sleeve and turning cylinder matched in clearance; Described cam is positioned at below base plate, and cam is fixedly connected with turning cylinder; The contoured surface of described cam is provided with annular groove, is provided with thimble between cam and base plate, and the bottom of thimble is provided with roller, and the width of roller is less than the width of annular groove; The top of thimble is positioned at the endoporus of lining; Described threaded rod is hollow stem, and the endoporus aperture of threaded rod is greater than the pin diameter of chain.
Adopt the chain provision for disengagement in this programme, comprise base, threaded rod and cam, threaded rod plays a part to compress chain, and cam provides power for dismantling chain.Upper backup pad is provided with the tapped through hole that threaded rod matches; Facilitate threaded rod can move up and down at gripper shoe place.Base plate is provided with counterbore, and the axial line conllinear of the center line of counterbore and tapped through hole; The chain being positioned at counterbore place can be compressed when guaranteeing that threaded rod moves down.Lining is provided with in counterbore; Counterbore plays support bushing.Described riser is provided with through hole, is provided with axle sleeve in through hole, is provided with turning cylinder in axle sleeve; Axle sleeve plays support rotating axle, and axle sleeve and turning cylinder can relatively rotate.Cam is fixedly connected with turning cylinder; Turning cylinder plays a supportive role to cam.The contoured surface of described cam is provided with annular groove, is provided with thimble between cam and base plate, and the bottom of thimble is provided with roller, and the width of roller is less than the width of annular groove; Roller rolls in the annular groove of cam, and cam rotates and thimble moved upward to be ejected by the bearing pin on chain.It is avoid roller sideslip in rotation process that cam contour face is provided with annular groove.The top of thimble is positioned at the endoporus of lining; The endoporus of lining play the guiding role to thimble.Described threaded rod is hollow stem, and the endoporus aperture of threaded rod is greater than the pin diameter of chain; Bearing pin on chain is bound to the endoporus place of threaded rod when being ejected, avoid bearing pin disorderly to fly to hurt sb.'s feelings when ejecting.
Operation principle of the present utility model and beneficial effect are: when using the provision for disengagement of this chain, first make threaded rod move to the direction away from lining, are then placed on lining by chain to be removed.Rotating rotating disk makes threaded rod move to the direction near lining, finally makes threaded rod support chain, compresses chain.Then make cam rotate, cam makes thimble move upward against the roller of thimble lower end to be ejected by the bearing pin on chain, be positioned at the endoporus place of threaded rod after bearing pin ejects.Then rotating threaded rod makes threaded rod move upward, and bearing pin falls down from the endoporus of threaded rod.Rotating cam makes thimble move to the direction away from lining, thus thimble is extracted from chain.The chain dismantled is taken off from lining.
Chain does not need to position chain with hand in unloading process, but is positioned by threaded rod.Avoid in chain unloading process, the probability that hand is injured, and the bearing pin of chain being positioned at the endoporus place of threaded rod after being ejected, avoiding bearing pin disorderly to fly to hurt sb.'s feelings when ejecting.This device realizes thimble by the principle of cam mechanism to move up and down fast.The utility model has the advantages that operating efficiency is high, safety coefficient is high as can be seen here.
Further, described lining is embedded with multiple equally distributed permanent magnet, and the upper surface of permanent magnet flushes with the upper surface of lining.Permanent magnet plays the role of positioning to chain, avoids people to position chain with hand, and it is that in the process that prevents from dismantling at chain, permanent magnet is extruded bad by chain, because permanent magnet fragility is larger that the upper surface of permanent magnet flushes with the upper surface of lining.
Further, oil groove is provided with in described axle sleeve.Turning cylinder, in rotation process, reduces the friction of turning cylinder axle sleeve by adding lubricating oil in the oil groove on axle sleeve.
Further, described cam adopts with turning cylinder and welds.Relative to cam and turning cylinder one-body molded for, cam and turning cylinder welding manufacture cost low, and easy to process.
Further, the screw thread of described threaded rod adopts double thread.For single thread, the distance that threaded rod rotates a circle advance is single threaded twice.
