Background

The positioner is a special welding auxiliary device, is suitable for the welding deflection of a rotary workpiece, and obtains an ideal welding position and welding speed. When a long-span workpiece is welded in the circumferential direction, the workpiece is often fixed on a clamp beam, two end parts of the beam are fixedly connected to a turntable of a positioner, and then a driving device drives the turntable to rotate relative to a fixed seat so as to realize circumferential displacement of the beam. In order to ensure the position stability of the cross beam, the cross beam and the clamp as well as the clamp and the turntable are generally connected through bolts, for a heavy-duty positioner, the connection mode has the condition that the center distance and the coaxiality of a driving end and a driven end are inconvenient to adjust, and once the cross beam expands with heat and contracts with cold, the displacement and the expansion force accumulated in the axial direction easily cause the positioner to be stopped and blocked.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.

Example 1:

the heavy positioner connecting mechanism of this embodiment connects anchor clamps crossbeam 3 in the both ends of anchor clamps crossbeam 3, including rotatable connect in the carousel 2 on positioner fixing base 1 to and be used for the coupling assembling 4 of the end connection on carousel 2 of anchor clamps crossbeam 3, the relative carousel 2 of direction along perpendicular to carousel 2 of coupling assembling 4 of the at least one end of anchor clamps crossbeam 3 removes. This kind of mode of setting up makes and has certain activity allowance between whole coupling mechanism and the anchor clamps crossbeam 3 in this direction, and 2 centre-to-centre distances of carousel at both ends are adjusted more nimble conveniently, reduce the centre-to-centre distance requirement to the machine of shifting, not only make things convenient for the installation of anchor clamps crossbeam 3 to dismantle, can also provide the activity space when taking place expend with heat and contract with cold for anchor clamps crossbeam 3. To long-span anchor clamps crossbeam 3, the influence that its telescopic power and displacement that accumulate in the axial were effectively cleared up to the coupling mechanism of this embodiment brought, and the self-adaptability is better, avoids the machine of shifting to take place the stagnation and the dead circumstances of card etc..

In this embodiment, as shown in fig. 1 and fig. 2, be equipped with socket 21 on carousel 2, the quotation of the perpendicular carousel 2 of axial of socket 21, coupling assembling 4 one end is used for coupling fixture crossbeam 3, the other end is equipped with the plug 41 with socket 21 plug-in connection, plug 41 and socket 21 plug-in connection can realize coupling assembling 4's axial displacement, thereby make fixture crossbeam 3 have the surplus of moving about when changing in the axial, this kind of mode of setting simple structure, it is less to current machine change of shifting, the practicality is higher.

In this embodiment, the cross sections of the socket 21 and the plug 41 are both rectangular, at least one pair of opposite inner walls in the socket 21 are inclined inner walls, the distance between the two inner walls is gradually reduced from the outer side of the turntable 2 to the inner side of the turntable 2, and the side wall of the plug 41 corresponding to the inclined inner wall is provided with a corresponding inclination angle. The clamp beam 3 is in the installation process, and due to the inclined fit between the plug 41 and the socket 21, the effect of automatic centering of the two ends of the clamp beam 3 can be realized, and the coaxiality requirement of the positioner is reduced. In another embodiment, the cross-sections of the socket 21 and the plug 41 may be circular, the inner wall of the socket 21 may be tapered, the inner diameter of the socket 21 may be gradually reduced from the outside of the turntable 2 to the inside of the turntable 2, and the plug 41 may be tapered in accordance with the socket 21.

In this embodiment, the tip of coupling assembling 3 in the coupling assembling 4 is equipped with connecting axle 42, and connecting axle 42 wears to establish in the through-hole that sets up on being fixed in anchor clamps crossbeam 3, and the connecting axle 42 mutually perpendicular of coupling assembling 4 at anchor clamps crossbeam 3 both ends, compares in parallel arrangement, can avoid anchor clamps crossbeam 3 whole along the axis of connecting axle 42 to subside.

In this embodiment, coupling assembling 4 of 3 one ends of anchor clamps crossbeam can remove 2 relatively turntables, and coupling assembling 4 snap-on of the other end makes anchor clamps crossbeam 3 have certain installation benchmark in the installation, in other implementation manners, also can adopt the equal mobilizable coupling mechanism in both ends, does not do this and does not describe repeatedly.

In this embodiment, when the clamp beam 3 is installed, a certain gap is left between the movable end of the connecting assembly 4 and the turntable 2, so as to further prevent the clamping stagnation phenomenon.
