Abstract
The utility model relates to an eccentric wheel type reinforcing bar butt-welder mould clamp which is mainly composed of an eccentric wheel, a supporting frame, a square shaft, a supporting frame seat, a clamping cap, a lying bar, a reverse spring, an adjusting screw, etc. The mould clamp can clamp the reinforcing bar, ensures the butt-welding quality, and has the characteristics of convenient operation, firm material, long service life, small size, light weight, easy movement and few operating staff. The mould clamp overcomes the defects that the supporting frame of the existing equipment slides on the reinforcing bar and scratches the reinforcing bar when the supporting frame moves forward. The mould clamp is suitable for the spot construction of buildings, dams, bridges and factories for cement constructional members, is suitable for the weld at different azimuths, and can cause the labor strength to be reduced by one to two times and the work efficiency to be increased by three to four times.
Description
The machine jig of using during a kind of steel bar butt welding is used for the fixing or locating support technical field of workpiece when belonging to welding.
At present the steel bar butt welding machine jig that uses is with screw-driving to prop up reinforcing bar, uses the removable jig support of hydraulic pressure overhead welding pushing tow then, and itself and reinforcing bar are moved to the solder joint direction, finishes butt welding.But use this jig often to occur the phenomenon that screw and support thereof slide along rebar surface easily, producing the degree of depth at rebar surface scratches, this is unallowed in some important construction occasions, because it has exceeded relevant construction required standard, seriously influenced welding quality, when reinforcing bar bears pulling force, occur fracture again again, caused construction quality defective.The manpower that this jig drops in construction is many, and efficiency is low.
The purpose of the present utility model is: overcome above-mentioned shortcoming and defect fully, made the steel bar butt welding quality good, guaranteed construction quality, reduced labor intensity, increased work efficiency.
Structural principle of the present utility model is: replace clamp-screw with eccentric wheel, rotation direction is consistent with reinforcing bar advance and retreat direction before and after the eccentric wheel.During use, two butt welding reinforcing bars are put into respectively be equipped with eccentric two stands, a support is for fixing, and another support vertical position welding is on the bar for sleeping in that can advance and retreat, and crouch bar and reverse spring are loaded in the carrier base, and the carrier base opening part is tightened with the card cap.On the carrier base of movable supporting frame both sides, be welded with and adjust the adjustment screw support that position, the movable supporting frame left and right sides is used, adjust screw and can make two reinforcing bars to be welded coaxial.When the beginning butt welding, bar makes its drive movable supporting frame move forward to the solder joint direction but hydraulic pressure driving and reversing mechanism pushing tow crouches, be milled with oblique groove in eccentric two on the inclined-plane, be convenient to block mutually with reinforcing bar, the reach of reinforcing bar also drives eccentric wheel and rotates, eccentric wheel to the span of reinforcing bar is strengthened, further the chucking reinforcing bar avoids support to slide along reinforcing bar, so how many supports moves forward, how many reinforcing bars also moves forward together, guaranteed welding quality.When rebar sizes was relatively large, available square shaft was fixed on eccentric wheel on another standby hole of top, and use principle is identical.
Characteristics of the present utility model are: be suitable for various job sites such as building, dam, bridge construction, cement components factory, be applicable to the steel bar butt welding in various orientation, this machine jig is simple in structure, manufacture easily, in light weight, portably use easy accessibility, sturdy and durable, the efficient height, to the tightening up, have good positioning of workpiece, guaranteed the butt welding quality of reinforcing bar.
Narrate most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 overall installation diagram of the present utility model.
Among the figure: eccentric wheel (1), square shaft (2), fixed support (3), movable supporting frame (4), the bar (5) that crouches, reverse spring (6), hole, garden (7), hole, garden (8), carrier base (9), adjustment screw (10), card cap (11).

The parts of this utility model most critical be its profile of eccentric wheel (1) as shown in Figure 2, in two of eccentric wheel (1), on the inclined-plane, be milled with oblique groove, recess can reach 2 millimeters deep, is to be used for tightening reinforcing bar.Supporting structure as shown in Figure 3, hole, two pairs of gardens is arranged on it, adjusting the eccentric wheel position when being used for butt welding thickness reinforcing bar uses, the support vertical position welding becomes fixed support (3) in the end that as shown in Figure 5 carrier base does not have fluting, and the support vertical position welding becomes movable supporting frame (4) on the concave surface of as shown in Figure 4 bar for sleeping in.Reverse spring (6) is placed earlier in the bearing (9), the bar for sleeping in (5) that will be welded with movable supporting frame (4) is again packed in the carrier base (9), the leg of movable supporting frame (4) just in time is positioned at the long fluting of carrier base (9), card cap (11) shown in Figure 6 is screwed in the threaded end of carrier base (9), falls outward to prevent bar for sleeping in.When the less reinforcing bar of butt welding size, the square shaft that has eccentric wheel (1) places on the hole, garden 1 of two stands, and when rebar sizes was big, the square shaft (2) that will have eccentric wheel (1) placed on the hole, garden (8).The reinforcing bar welding that this machine jig can be used for various orientation is an example with the implementation process of vertical position welding, describes implementation process.When the upright straight reinforcing bar of bottom has been processed firmly, fixed support (3) is deposited end, and will descend reinforcing bar to insert in the gap of eccentric wheel (1) and fixed support (3), make and treat that solder joint is positioned in the middle of the two stands, with the square shaft in the eccentric wheel under the spanner rotation, till supporting the position reinforcing bar, to go up reinforcing bar again inserts in the gap of eccentric wheel and movable supporting frame, two reinforcing bars are offseted adjust square shaft and mix up with adjustment screw (10) again to prop up reinforcing bar, the relative position of following reinforcing bar also makes it really coaxial, after the welding beginning, two steel bar ends begin fusing to be made its compressing reverse spring (6) and drives movable supporting frame (4) and last reinforcing bar moves down together with the hydraulic push rod pushing bar (4) that crouches, eccentric wheel moves down and rotates with reinforcing bar, and tighten reinforcing bar more, and reach the firm purpose of butt welding, guaranteed construction quality.
Claims (3)
1, a kind of eccentric wheel type steel bar butt welding machine jig, form by eccentric wheel (1), fixed support (3), square shaft (2), movable supporting frame (4) bar (5) for sleeping in, reverse spring (6), carrier base (9), card cap (11), adjustment screw (10), it is characterized in that eccentric wheel (1) is placed on the hole, garden (7) or hole, garden (8) of fixed support (3), movable supporting frame (4) with square shaft (2).
