Description
Technical field
The present invention relates to a kind of mechanical engineering device, particularly a kind of forging manipulator lifting mechanism.
Background technology
Forging manipulator is the important auxiliary equipment of free-forging hydraulic group, is also that the major mechanical that the career developments such as national heavy industry, nuclear power, Aero-Space and wind energy are badly in need of one of is equipped.If complete a whole set of forging process, forging manipulator seven the forging operation functions such as jaw clamping, claw beam rotation, claw beam lifting, claw beam pitching, claw beam are traversing, claw beam swing, large vehicle walking that need realization to comprise.Wherein, jaw clamping, claw beam rotate, large vehicle walking three actions are separate structure, and respectively by motor or hydraulic cylinder drive, clamp realizes clamping and the spinfunction of workpiece, and walking function born by cart, and remaining action is realized by hoisting mechanism.Current use more widely large-tonnage forging manipulator form has parallel link mechanism and two kinds, rocking lever formula mechanism.Wherein the mobile decoupling of parallel link forging manipulator is higher, be easy to control, but most of parallel link forging manipulator is only containing single pitching hydraulic cylinder, as German patent DE 20108277, Chinese patents 201010543863.5,201010133714.1,201210421383.0 etc., the manipulator holding capability of this structure is not very large.And in Chinese patent 201010193620.3 and 201210182110.5, although containing two pitching hydraulic cylinders, but pitching hydraulic cylinder or be placed in the middle of synchronizing bar or be directly connected with frame, in lifting process, stressed size variation scope comparatively greatly, easily makes the depth of parallelism of lifting reduce.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, holding capability is strong, lifting is stably containing two pitching linear actuator parallel link forging manipulator lifting mechanisms.The present invention mainly comprises lifting device, swings device, front-back buffer, claw beam and frame.Described lifting device comprises claw beam, front slide bar, a pair front overhang peg, front lift arm, a pair synchronizing bar, rear lift arm, rear slide bar, left pitching linear actuator, right pitching linear actuator and is elevated linear actuator a pair; The described device that swings comprises a pair front left and right linear actuator and a pair rear left and right linear actuator; Described front-back buffer cushions linear actuator before and after comprising a pair; Described a pair lifting linear actuator, a pair front overhang peg, cushion linear actuator before and after a pair and a pair synchronizing bar is all symmetrically arranged.
Wherein, claw beam front end is connected with front slide bar by moving sets, these front slide bar two ends are connected with a pair front overhang peg lower end respectively by ball pivot, this front overhang peg upper end is connected with the crossbeam of a pair front lift arm by ball pivot, this front lift arm top is connected with synchronizing bar front end by ball pivot, this synchronizing bar rear end is connected with rear lift arm top by ball pivot, and after a pair, left and right linear actuator stiff end is connected in above-mentioned rear lift arm both sides respectively, and its tache motorice withstands on the two ends of rear slide bar respectively; Above-mentioned forward and backward lift arm is connected with frame with the turning joint that axis left and right horizontal direction is arranged respectively; Left pitching linear actuator upper end is connected with on the left of above-mentioned rear slide bar by ball pivot, and its lower end is connected with claw beam back stay left end by ball pivot; The turning joint that right pitching linear actuator upper end is arranged by axis left and right horizontal direction is connected with on the right side of above-mentioned rear slide bar, and its lower end is connected with claw beam back stay right-hand member by ball pivot; A pair lifting linear actuator upper end is connected with above-mentioned front lift arm bottom respectively by ball pivot, and its lower end is connected with frame by ball pivot; Cushion linear actuator front end before and after a pair to be connected with in the middle part of above-mentioned a pair front overhang peg by ball pivot, its rear end is connected with claw beam mid link by ball pivot; A pair front left and right linear actuator stiff end and claw beam are connected, and its tache motorice withstands on the inwall of frame both sides respectively.
Each action of forging operation is respectively by each device complete independently of this forging manipulator lifting mechanism.During elevating movement, a pair lifting linear actuator promotes front lift arm, drives a pair front overhang peg to be synchronized with the movement up and down; Lift arm after simultaneously being promoted by a pair synchronizing bar, slide bar after rear lift arm drives, thus drive two asymmetrical pitching linear actuators of structure to be synchronized with the movement up and down, and then drive claw beam to do synchronization lifting motion.During elevating movement, two asymmetrical pitching linear actuators of structure are synchronized with the movement and directly promote claw beam rear portion and make it do elevating movement.Traversing and oscillating motion completes by swinging device, a pair front left and right linear actuator promotes claw beam front portion and drives claw beam to realize transverse movement, after a pair, left and right linear actuator promotes rear slide bar, rear slide bar drives two asymmetrical pitching linear actuators of structure, drives claw beam to realize transverse movement from claw beam rear portion.Current, rear left and right linear actuator driving direction is consistent and size is identical time, claw beam realizes transverse motion; When current, rear left and right linear actuator driving direction is contrary or drive volume is different, claw beam realizes oscillating motion.In cart Acceleration of starting, decelerating phase and the forging process for fuel process of stopping, by cushioning the passive stretching motion of linear actuator before and after a pair, realize the kicking motion that claw beam adapts to front and back sudden change external force.
The present invention compared with prior art tool has the following advantages:
1. the pitching linear actuator that two structures are different is directly connected with claw beam afterbody, improves the holding capability of manipulator;
2. a pair front overhang peg is directly hinged with front lift arm, and structure is simple, and lifting is steady, improves the integral rigidity of manipulator, is applicable to the forging operation of large-scale/ultra-large type forging.
