The essence of the unit that it has a wire feeder part and a connector part, the carrying body of the wire feeder part and the house of the connector part is designed as a unit in one piece, suitably made of plastic, and the inlet opening of the wire feeder part is situated opposite to the wire lead-in opening on the inner side of the connector part joining to the bottom of the nest for the wire guide, in a given case there is an inlet piece in the inlet opening, the path of the wire defined by these two openings is going between the feed roll and the pinch roll as is known in the prior art, and further, either the axle of the pressure arm with the pinch roll mounted on it or the axle of the fixing arm is fixed to the inner end of the house of the connector part, suitably to a projection established there, and the axle of the other arm is fixed to a projection on the carrying body of the wire feeder part opposite to the other projection, making angular motion of the arms possible.
Description
The present invention relates to a kind of wire feeder and connector unit, the structure of this unit is applicable to welding wire is advanced in the cable of a welding torch in the mode that can further prevent its deflection, it can be used as a unit of welder especially like this, as the combined unit of connector on a kind of end of connection cable of receivability welding torch and the welding wire of feeding simultaneously.
As known, the effect of the welding wire feeder of welder is that welding wire is pulled out from bobbin, and it is pushed makes in torch cable and the connector that links to each other of device power supply, can be pushed into welding torch with constant speed under the guiding of torch cable to guarantee welding wire.
In known welder; the cable that welding torch is linked to each other with welder is constructed in such a way; promptly; carry the high-current conductor of welding current and carry the control signal weak current lead that is used for welding torch closely to be laid on mutually in the public tube-like envelope; the solenoid (spiral) that a guiding welding wire is arranged in the inner core of cable; and between the shell of cable and inner core, there are a pipeline or a conduit; to carry protective gas; for example United States Patent (USP) 4; the sort of structure that proposes in 529,861 the patent specification.On the end near device of these cables, a connector is installed, this connector is configured to be complementary with cable, and this connector can connect with other connector on the top board that is installed in device generally speaking by spiral and combines, and this connector is configured to, when connector interconnects and fixedly the time, can be simultaneously between the live of connector and carrier gas element, set up required connection, and the wire nozzle nose shape piece of cable upper connector also can be assembled in the corresponding jack that forms in the connector that is contained on the device, to guarantee that welding wire does not have deflection or the shifting ground imports in the cable of welding torch from device.The so-called inboard that is installed in the connector facing device inner space on the device is provided with a suitable terminal and an air feed piece, the lead that is loaded with welding current can link to each other with these terminals with the lead that is loaded with control signal, and gas pipeline can link to each other with the air feed piece, in addition, welding wire can be introduced in the connector by middle seal wire spare, and this seal wire spare feeds the jack of welding wire and be arranged in wherein liner.
By wire feeder, welding wire moves in connector and cable, and wire feeder normally is fixed on the inside of device.The common structure of known wire feeder is as follows: they have: a carrying body, and this body both can be cast, and also can be made by sheet metal; The roller of a pair of or two pairs of feeding welding wires, they are made up of the feed rolls and the pinch roll that are positioned on carrying body one side, and in practice, the axle of feed rolls is vertical with the installing plate that carries body; In addition, wire feeder also has one or more pressure arms, and these pressure arms are fixed by a swivel joint and carrying body, and pinch roll is fixed by the bearing and the pressure arm of a free-running operation, and this bearing can prevent that pinch roll from moving axially; In addition, wire feeder has a fixed arm, and this fixed arm locks together pressure arm and carrying body by pressure can be provided by the elastic force that prestressing force is regulated; And have a locking device, this device is used for fixing the closing position of pressure arm with the carrying body.In the position of pressure arm near the carrying body, fixed arm makes it press the feed rolls relative with it so that the mode of wire clamp between two rollers of feeding flexiblely oppressed pinch roll, and in open position, pinch roll separates with feed rolls.
In a sidewall of carrying body, an opening that is used for the first seal wire spare is arranged, and an opening that is used for the second seal wire spare is arranged in another sidewall relative with this sidewall, thereby in the position that pressure arm and carrying body are fixed, formed the path of the welding wire between feed rolls and pinch roll.Be applicable to that the first and second seal wire spares that import and derive welding wire use a helical spring to construct usually.
Driver element is installed on another installing plate of carrying body, and the output shaft of driver element is forced directly or indirectly to be coupled by feed rolls or roller and carried moment of torsion.In addition, the carrying body has a bottom surface, and the hole in the bottom surface that wire feeder can be threaded by use is installed on support plate, console, supporting member or the like, and makes wire feeder near connector as far as possible.For example United States Patent (USP) 5,155, and some examples of this type of wire feeder are arranged in 332,4,404,450,4,898,317,5,053,598 and 5,137,223.
In order to use welder, welding wire must guide by wire feeder, and must be directed in the connector on the device, and this need open device usually.When using this device, in the time of in welding wire is stuck in device, when welding wire need change, just must repeat this process again and again.The condition that welding wire correctly moves is, the wire feeder and the connector that are contained on the device that are used to guide welding wire should be approaching mutually, welding wire just can deflection or distortion in the path between wire feeder and the connector like this, this deflection or bending can cause the device operation to be broken down, and device need be opened, and needs again welding wire to be inserted to eliminate fault.For example United States Patent (USP) 4,102, and some structures are like this arranged in 483 the patent specification, and these structures are used in and guide welding wire between wire feeder and the workpiece in the correct guiding cable on the path, yet in practice, what these structures can not be real works.
In addition, also has so common problem, when the structure welder, to secure a position (generally being inner) at device for wire feeder, wire feeder fixing in this position the frame fixation of bottom surface by wire feeder and device (generally be) with device, and this position should be as far as possible just can be easily near wire feeder under the situation of stripping device, in addition, wire feeder should be positioned at a kind of so come-at-able position, device inside, promptly, this position can be inserted easily, shift out or change welding wire, change roller, not really skilled personnel regulate pressure or the like, even also should operate in this place in hard situation.
Our target of the present invention is to address the above problem, that is to say, be installed on the device wire feeder and and connector between set up the path of a welding wire, thereby, welding wire can prevent welding wire deflection or crooked guiding substantially for providing, like this, wire feeder and connector can enter easily, and it can carry out required maintenance and adjusting in the device course of normal operation easily.
