As shown in fig. 1 to 5, the rotatable welding positioning mould for the steel wire framework of the car seat comprises a large bottom plate 1 for bearing the steel wire framework and two welding tyres 2 assembled along the length direction of the top of the large bottom plate 1, wherein the welding tyres 2 comprise a positioning clamping mechanism 21 for fixing the steel wire framework and an ejection mechanism 22 for ejecting the steel wire framework, the welding tyres 2 comprise a plurality of positioning clamping mechanisms 21, and an independent ejection mechanism 22 is also installed at the junction of the two welding tyres 2.

The positioning and clamping mechanism 21 comprises a supporting base 211 fixedly arranged on the top of the large base plate 1 and a supporting table 212 arranged on the top of the supporting base 211 along the horizontal direction, a clamping cylinder 213 is fixedly arranged at the bottom of the supporting table 212, the output end of the clamping cylinder 213 penetrates through the bottom and the top of the supporting table 212 in sequence and extends to the outside, a first connecting rod 215 is assembled at the output end of the clamping cylinder 213, a pressure foot 214 is hinged at the middle of the top of the supporting table 212, one end of the pressure foot 214 is hinged with one end of the first connecting rod 215, a fixed detection block 216 is fixedly arranged on one side of the supporting table 212, as the welding tire 2 comprises a plurality of positioning and clamping mechanisms 21, and the plurality of positioning and clamping mechanisms 21 are arranged according to the shape of the steel wire framework of the automobile seat, the steel wire framework is conveniently clamped, the position deviation of the steel wire framework during robot welding is avoided, the connection points of the steel wire framework are difficult to be welded together, the welding quality of the steel wire framework is influenced, the welding points on the steel wire framework are positioned between two adjacent positioning and clamping mechanisms 21, in addition, in order to better clamp the steel wire framework, the shape of a part of the positioning and clamping mechanism 21 are divided into a long rod shape and a T shape according to different clamping position.

The liftout mechanism 22 includes the jacking cylinder 221 of fixed mounting at big bottom plate 1 top, the output at jacking cylinder 221 top is equipped with second connecting rod 222, the top of second connecting rod 222 is equipped with the guide lantern ring 224, big bottom plate 1's top is followed its direction of height fixed mounting and is had guide bar 223, and welds the liftout mechanism 22 that child 2 contains and independently installs the liftout mechanism 22 that welds child 2 juncture two and distinguish and lie in: the second connecting rod 222 of the two is different in shape, the former is U-shaped, and the latter is in a straight shape.

In this embodiment, the top of the fixed detection block 216 is provided with a workpiece placing groove 217, and the workpiece placing groove 217 is located below the other end of the presser foot 214, so that the advantage of the arrangement is that the control circuits of the clamping cylinder 213 and the jacking cylinder 221 in each welding tire 2 are connected in series, but the control circuits of the two welding tires are connected in parallel with the main circuit, so that a worker can control the clamping cylinder 213 and the jacking cylinder 221 in the two welding tires 2 to respectively extend or shorten, thereby driving the presser foot 214 in the two welding tires 2 to clamp or loosen the steel wire framework, and the actions in the two welding tires 2 are opposite, thereby staggering the welding operation and the placing operation, so that the worker can safely take away the loosened steel wire framework when welding the clamped steel wire framework by the robot, and then put on the steel wire framework to be welded.

In this embodiment, the one end activity of guide bar 223 is pegged graft in the inside of guide sleeve ring 224, and the benefit that sets up like this lies in, can carry out jack-up or when descending at jacking cylinder 221 to second connecting rod 222 for guide sleeve ring 224 can vertically reciprocate along the surface of guide bar 223, comes in proper order to carry out spacing direction to reciprocating of second connecting rod 222, avoids appearing the skew at its reciprocating in-process, and is difficult to realize the jack-up effect to steel wire framework.

In this embodiment, the whole shape of second connecting rod 222 is the U-shaped, and the equal fixed mounting in top at second connecting rod 222 both ends has the ejector pin, the benefit that sets up like this lies in, because the steel wire framework's that liftout mechanism 22 jack-up position is different, thereby set up two kinds of liftout mechanisms 22, and displacement difference between the two is just different with second connecting rod 222's shape, be U-shaped and a font respectively, thereby can mutually support and steady jack-up the irregular steel wire framework of shape, so that the quick taking of work safety.

In this embodiment, the both sides at big bottom plate 1 top all are equipped with first upset handle 3 and second upset handle 4 along its width direction, the benefit that sets up like this lies in, all be provided with first upset handle 3 and second upset handle 4 in the both sides of big bottom plate 1 respectively, the mounted position that is in first upset handle 3 and second upset handle 4 of homonymy is staggered on the width direction of big bottom plate 1, and the length of first upset handle 3 and second upset handle 4 also has very big difference, thereby can be through switching first upset handle 3 and second upset handle 4, make the rotatory different angle of big bottom plate 1, so that it can adapt to more multiple type welding robot.

In this embodiment, the installation screw that is used for the equipment is all offered on the surface of first upset handle 3 and second upset handle 4, and the benefit that sets up like this lies in, and convenient to use person transversely assembles big bottom plate 1 through fastening bolt on playing the auxiliary assembly who bears and drive effect to it, dismantles or installs it when the maintenance of later stage overhauls to the person of facilitating the use examines or changes each part on big bottom plate 1.

In this embodiment, the length side fixed mounting of big bottom plate 1 has shift knob 5 who is used for controlling two welding child 2, the benefit that sets up like this lies in, shift knob 5 sets up the edge at big bottom plate 1, even it is in welding robot orbit's blind spot department, the risk of being touched by welding robot mistake can not appear, also can make it leave to use enough nearly, so that use can be when breaking down, closing circuit that can be timely, make it in time shut down and wait for maintainer to overhaul it.

In this embodiment, the whole shape of welding child 2 cooperatees with steel wire framework's frame shape, the benefit that sets up like this lies in, because the collision dynamics of welding robot and steel wire framework's contact point is great, in order to avoid steel wire framework to be strikeed by welding robot and the offset appears, so under the prerequisite that does not influence robot welding action, the quantity that positioning and clamping mechanism 21 in welding child 2 used is as much as possible, and make them arrange the assembly on big bottom plate 1 according to steel wire framework's shape, thereby can furthest fix steel wire framework spacing, and improve robot welding operation's precision, improve the welding quality of every welding point, avoid influencing the holistic support intensity of steel wire framework.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
