The welding machine suspension holdfast
Technical field
The utility model relates to a kind of suspension holdfast that is used to hang and carry the welding wire car, belongs to the mechanical technology equipment.
Background technology
In the produced on-site process of rail vehicle, need carry out assembly welding at present to each member that constitutes car body.As adopt the welding wire car that welding processing is carried out in all kinds of extruding or injection moulding section bar.
The welding wire car that the technology scene is adopted need hang, and moves according to the different weld seams of member.The suspension of existing welding wire car does not still have standard and isolated plant, still the lifting that relies on artificial push-and-pull and manipulator of welding wire car, not only wasted time and energy, increased operator's labour intensity, and be difficult to guarantee to operate the use radius of welding machine handgrip, the efficient of welding operation is not high.
The utility model content
Purpose of design of the present utility model is to provide a kind of welding machine special suspension holdfast, needs and the welding wire car is hung at the welding post of tool member, realizes the selection of welding post easily, the flexible adjustment of welding machine handgrip position.
For realizing above-mentioned purpose of design, described welding machine suspension holdfast mainly has following structure:
One is fixedly connected on the fixed mount on the basis, and the upper lateral part of fixed mount connects a pedestal by bearing pin.
One side of linkage is connected on the pedestal, and another side connects a welding wire car hanging seat downwards.
Described linkage connects a side of pedestal, and its top is fixed on the upper end of pedestal, and its underpart is slidingly connected in the lower end of pedestal.Described linkage has at least one group of connecting rod that is hinged.
As above-mentioned technical characterictic, the welding wire car is hung by hanging seat, after welding post is determined, carry the welding wire car to the station top by the pushing linkage, the operator can use the welding machine handgrip to operate easily.
During the push-and-pull linkage, slide on pedestal in the bottom of linkage, and the connecting rod that is hinged both can be stretched, and can be contracted again, thereby carry the welding wire car to move back and forth.
For improving linkage and suspension and steering capability, further improvement project can be that linkage has two groups of connecting rods, interconnects by the middle part major axis between every group of connecting rod.
The outer cover of middle part major axis is provided with spacer, and spacer runs through the connecting rod at two ends, and spacer inside is provided with lining; Arranged outside at every group of connecting rod has a pair of locking nut that is used for fixing the middle part major axis.
Can provide more firm suspension strut by two groups of connecting rods, and the bottom of every group of connecting rod is slidingly connected on pedestal, the synchronism of connecting rod telescopic moving can be provided again.
For further improving the mobile flexibility of connecting rod, the bottom that connects pedestal one side at described linkage is provided with roller, and the sidepiece of pedestal is provided with slideway.
Connecting rod on the same group is hinged by bolt.
As above content, described welding machine suspension holdfast has the following advantages:
Can realize the selection of welding post and the flexible adjustment of welding machine handgrip position easily, time saving and energy saving, reduce working strength of workers effectively, and guarantee the use radius of welding machine handgrip, welding operation efficient is higher.

Fig. 3 is the I portion enlarged diagram of Fig. 2;
As shown in Figure 1 to Figure 3, fixed mount 1, bearing pin 2, pedestal 5, roller 6, linkage 10, welding wire car hanging seat 11, middle part major axis 14, spacer 15, lining 16, locking nut 17.
The specific embodiment
Embodiment 1, and as shown in Figure 1 to Figure 3, described welding machine suspension holdfast includes the fixed mount 1 that is fixed on the basis, and the upper lateral part of fixed mount 1 connects a pedestal 5 by bearing pin 2.
One side of linkage 10 is connected on the pedestal 5, and another side connects a welding wire car hanging seat 11 downwards.
In a side of linkage 10 connection pedestals 5, its top is fixed on the pedestal 5 by bearing pin, and its underpart is provided with roller 6, and the sidepiece of pedestal 5 is provided with slideway.
Described linkage 10 has two groups of connecting rods, interconnects by middle part major axis 14 between every group of connecting rod.The outer cover of middle part major axis 14 is provided with spacer 15, and spacer 15 runs through the connecting rod at two ends, and spacer 15 inside are provided with lining 16.
Arranged outside at every group of connecting rod has a pair of locking nut 17 that is used for fixing middle part major axis 14.
Connecting rod on the same group is hinged by bolt.
