Description
Technical field
The present invention relates to a kind of steel bar truss feeding step pitch regulation fixing apparatus, adjust stationary device for the steel bar truss feeding step pitch of steel bar truss welding machine production line specifically, belong to technical field of welding equipment.
Background technology
The steel bar girder point is welded on base plate and forms steel bar truss floor support plate, is applied to industry and civil buildings and structures.When steel bar girder is used for concrete floor slab construction, it is layed on beam, to bear concrete gravity and construction loads.Simultaneously, steel bar girder is used as again the permanent framework of steel reinforcement of floor.
The steel bar truss welding machine production line is exactly the biscuit steel bar welding to be connected into to the welding equipment production line of steel bar girder.The steel bar truss feeding step pitch guiding mechanism of original steel bar truss welding machine production line drives eccentric shaft to adjust the steel bar girder internode with gear pair, and without fixture.Motor reducer swings with actuating arm, and reliability is low fragile, and the accumulated error that the steel bar girder internode of producing (steel bar girder nodal pitch) exists is larger, thereby affects the steel bar girder length in same batch, can not meet the demand of production.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of steel bar truss feeding step pitch regulation fixing apparatus is provided, can effectively prevent that larger accumulated error from appearring in the steel bar girder internode in same batch, enhance productivity, meet the demand of producing.
According to technical scheme provided by the invention, the steel bar truss feeding step pitch regulation fixing apparatus comprises actuating arm, actuating arm comprises interconnected the first actuating arm support arm and the second actuating arm support arm, and the first actuating arm support arm end is rotationally connected the stepping link arm by the first rotating shaft.Actuating arm middle part eccentric position is rotationally connected back shaft, and back shaft, by the bearing connection bracket, is characterized in that: back shaft one end connects motor reducer, and the other end connects encoder by shaft coupling.Back shaft is by the flat key connecting brake, and brake is fixed on the brake installing rack.The second actuating arm support arm end is rotationally connected the oil cylinder link arm by the second rotating shaft, link arm in the middle of upper end, oil cylinder link arm middle part is rotationally connected by the 3rd rotating shaft, and the middle link arm other end is rotationally connected back shaft.Oil cylinder link arm rear end is rotationally connected the piston rod of hydraulic Step Cylinder by the 4th rotating shaft.
Further, brake is positioned at the end that back shaft connects encoder.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, with motor reducer, directly drives eccentric shaft, has eliminated the accumulated error that gear drive causes, is applicable to the number of turns of rotating with program controlled motor; Centre-to-centre spacing on actuating arm between each fulcrum is constant, has guaranteed the benchmark that steel bar truss feeding step pitch is adjusted; Motor reducer is fixed on frame, no longer follows actuating arm and swings, and has improved service life and reliability; After the steel bar girder pitch is adjusted, brake makes the actuating arm initial position constant by fixing eccentric shaft, thereby effectively prevents that the steel bar girder pitch from larger accumulated error occurring, and guarantees the steel bar girder length of same batch, enhance productivity, meet the demand of producing.

The specific embodiment
Following the present invention is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises actuating arm 2, and actuating arm 2 comprises that interconnected the first actuating arm support arm 12 and the second actuating arm support arm 13, the first actuating arm support arm 12 ends are rotationally connected stepping link arm 1 by the first rotating shaft 14.Actuating arm 2 middle part eccentric positions are rotationally connected back shaft 4, and back shaft 4 is by bearing connection bracket 5.
The second actuating arm support arm 13 ends are rotationally connected oil cylinder link arm 7 by the second rotating shaft 15, link arm 6 in the middle of oil cylinder link arm 7 upper ends, middle part are rotationally connected by the 3rd rotating shaft 16, and middle link arm 6 other ends are rotationally connected back shaft 4.Oil cylinder link arm 7 rear ends are rotationally connected the piston rod of hydraulic Step Cylinder 8 by the 4th rotating shaft 17.
Operation principle of the present invention is: the distance between the center that is connected center and back shaft 4 of hydraulic Step Cylinder 8 and oil cylinder link arm 7 is brachium a initiatively, between the center that is connected center and back shaft 4 of stepping link arm 1 and actuating arm 2 apart from being driven brachium b.Motor reducer 3 drives actuating arm 2 around back shaft 4 center rotatings, the connection center of middle link arm 6 and the center bias of back shaft 4.When middle link arm 6 rotates, stepping link arm 1 moves up and down with the center of the relative back shaft 4 of connection center meeting of actuating arm 2, make the active brachium b of hydraulic Step Cylinder 8 and the driven brachium b of stepping link arm 1 change, hydraulic Step Cylinder 8 promotes the center rotating of the relative back shaft 4 of actuating arm 2 by middle link arm 6 and oil cylinder link arm 7, actuating arm 2 promotes stepping link arm 1 and moves horizontally, at hydraulic Step Cylinder 8 stroke c under constant prerequisite, stepping link arm 1 move horizontally the distance be that steel bar truss feeding step pitch d changes, thereby realize the adjustment of steel bar truss feeding step pitch.After adjusting the feeding step pitch of steel bar girder, brake 10 is fixed the rotation of back shaft 4, can effectively prevent from guaranteeing that because of the loosening accumulated error caused of back shaft 4 the steel bar girder length of every batch is consistent, meets Production requirement.
