Description
Technical field
The utility model relates to a kind of snap joint locking device of improvement, belongs to mechanical interlocking equipment technical field.
Background technology
The plurality of advantages such as mechanical interlocking is safe and reliable with it, flexible movements are widely used in daily production, life.Large to spaceship docking, the locking of Aircraft Air oiling pipeline, the little locking to safety belt buckle, various equipment top connection uses various mechanical interlock mechanism all in a large number.In iron and steel enterprise, in cold rolling mill oil-air lubrication, the locking of snap joint is the one end continuing to live snap joint on bearing block to pneumatic jack by cylinder, and moves together along with bearing block; Snap joint is divided into male and female two parts, and wherein male is by being threaded on the cylinder bar of cylinder, and female is arranged on bearing block; After roll pushes milling train, the cylinder snap joint of stretching out forward with male part combines with bearing side female and backs down check valve, and at this moment oil gas is connected to bearing block fuel feeding; Bearing block in play process as long as no the extreme position exceeding cylinder, with the use of snap joint can be held out against by cylinder and combine, reach the object of sustainable supply oil gas.But in normal production, due to factor impacts such as milling train bottom bracket base copper slide plate wear extent is different, cylinder base bolt loosens, the distortion of cylinder cylinder rod bending, usually cause the side snap joint of oil gas male and female not align, cause oil gas normally can not enter bearing block thus cause bearing block to burn.Cold rolling for Handan Iron and Steel Co West, occur more than 3 times because oil gas connects the accident causing bearing block to burn not in place every year, cause direct bearing spare part to be lost in about 1,000,000, the direct motion of also serious restriction production simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of snap joint locking device of improvement, in this device work, there is larger fault-tolerant ability, can not wear and tear because of bearing block copper shoe, cylinder base loosens, the change of cylinder cylinder rod bending deformation factor causes male and female snap joint can not in conjunction with the problem causing bearing damage, solve the defect in background technology.
The technical scheme solved the problems of the technologies described above is:
A kind of snap joint locking device of improvement, formation comprises snap joint male, cylindrical housing, the retaining mechanism being assemblied in enclosure and cylinder, U-shaped locking arm is fixed along its central axial direction in snap joint male side, two locking arms are symmetrical with snap joint male central axis, distance between two locking arms is greater than housing diameter, on two locking arms, symmetry has the contrary groove of opening direction, snap joint male right-hand member anchor tip spring; Described retaining mechanism comprises hollow slide block, be fixed on slide block left end and the cylindrical shape slide bar vertical with slide block end face, be sheathed on slide bar and and its fixing annular anterior lid, be sheathed on slide bar and its two ends respectively and drive end bearing bracket and slide block end face sliding block spring, cylindrical base, the built-in ladder tubular latch segment between base and slide block, annular rear end cap and the base spring fixed; Rear end cap right side is fixed in cylinder front end; Described base spring one end is through base center and latch segment interior step face is fixed, the other end and rear end cap left end offset; Drive end bearing bracket and rear end cap fixed cap are located at shell upper and lower side, slide block outer circumferential side is fixed with positioning key, outer casing inner wall is offered along its axis direction the chute matched with positioning key on slide block and is realized the slip of positioning key in chute and locate, the check lock lever of two deads in line is fixed in the two sides that latch segment is relative, check lock lever is vertical with housing central axis, and shell shell wall has for the through hole through check lock lever in check lock lever extended spot; The central axes of snap joint male, slide block, latch segment, base and cylinder; Described slide block right side offers at least three inclined-plane slideways along its circumference with equidistant from distance, the slideway matched with inclined-plane, slide block right side slideway quantity and size is offered in described latch segment both ends of the surface and base left side, and the diameter of described joint spring is between slide bar internal-and external diameter; The coefficient of elasticity K3 of described base spring is greater than the coefficient of elasticity K1 of joint spring; The coefficient of elasticity K1 of joint spring is greater than the coefficient of elasticity K2 of sliding block spring; When joint spring, sliding block spring and base spring all in a state of nature time, slide bar left end and joint spring offset, and be not in contact with each other between slide block and latch segment, base, now, check lock lever is arranged in two grooves of locking arm.
Above-mentioned a kind of snap joint locking device, described slide block, latch segment are cylindrical shape with base and external diameter is identical, the described inclined-plane slideway be opened on slide block, latch segment and base end face is respectively 4, the orthographic projection of inclined-plane slideway is at right angles trapezoidal, and trapezoidal hypotenuse and base are 30 ° ~ 60 ° angles; The positioning key of described slide block outer circumferential side is 4, lays along slide block circumference is average.
Above-mentioned a kind of snap joint locking device, described base annular right side and rear end cap is had corresponding screw, is connected between base and rear end cap by connecting bolt.
The utility model locking action process is: in roll change, impeller-hub bearing drives snap joint male to move to cylinder by roll shifting hydraulic cylinder, joint spring and slide bar contact gradually and hold out against, due to K1 > K2, then time initially, the elastic shrinkage force F2 of sliding block spring is less than the elastic extension power F1 of joint spring, along with the acting slider of joint spring top clamping power moves axially along the chute on shell, the inclined-plane slideway of final slide block and latch segment ramps contact drive latch segment along turning clockwise, and latch segment drives check lock lever to be locked in the groove of U-shaped locking arm, when needing to unlock separation, bearing block is to cylinder direction axial advance, constantly increase because sliding block spring constantly extends its elastic contractile force F2, the situation of F2 > F1 will be there will be, at this moment will there will be contact surface between latch segment and slide block to separate gradually, and the U-shaped locking arm of now snap joint male will continue to move axially with check lock lever, check lock lever drive latch segment move axially until with the inclined-plane ramps contact on base, because base is fixedly connected with rear end cap bolt, so base can not rotate, latch segment drives by base inclined-plane slideway and is rotated counterclockwise, thus check lock lever is separated with the groove on snap joint locking arm, realize the releasing process of snap joint.
The beneficial effects of the utility model are:
The utility model utilizes retaining mechanism nipple spring, sliding block spring, base spring, slide block, cooperatively interacting between latch segment and base realizes the locking of snap joint male, unlocks separation process; Snap joint male is fixed on together with female in bearing block can along with bearing block together action on bearing block.This device action is reliable, there is larger fault-tolerant ability, because holding out against by cylinder in its work, therefore avoid because of the wearing and tearing of roll chock copper shoe, cylinder base loosens, cylinder cylinder rod bending deformation factor causes male and female snap joint can not in conjunction with problem.To effectively can ensure that oil gas enters bearing block, avoids bearing block burnout failure for Oil/Gas Pipe from center of the present utility model through being connected with snap joint male.
