Chinese patent application 200820103719.8 discloses a kind of electric welding tong with steady rotating heads, comprise electric welding caliper, binding clip and conductive plate, it is characterized in that being provided with swivel head in binding clip, described swivel head is two, swivel head by rotating shaft and binding clip hinged, rotating shaft outer end is respectively equipped with and rotates manipulation part and rotational lock knob.

The electrode holders that Chinese patent application 01228059.3 1 kinds of chucks can rotate relatively with lever, the overall vice body of original electrode holders is divided into chuck and lever two parts by it, with attachment screw, both are connected, angle between chuck and lever can be regulated arbitrarily, to meet actual needs in the scope of 0 °-180 °.In chuck sheath side, adjustment screw, spring protecting sleeve, spring, compression pin are installed successively, under spring force, compress between pin and chuck and namely produce a shearing force, be enough to clamp welding rod; Even if compress pin in use to wear and tear, by regulating adjustment screw to increase spring pressure, still welding rod can be clamped.

Chinese patent application 97244537.4 discloses a kind of Dual-head rotating electric welding tongs, it comprises jaw (1) and handle (2), it is characterized in that jaw (1) is made up of front jaw (3) and deutomala (4), middle part is equipped with pinching screw (5), in hammerhead shape, have upper and lower two jaws (6,7), the electric conductor (8) in the middle part of deutomala (4) and handle (2) is hinged.

Chinese patent application 201120134396.0 provides a kind of electrode holders of Universal rotary location type chuck, belongs to welding apparatus technical field, is intended to solve existing electrode holders tip for fixing fast knot structure, problem comparatively loaded down with trivial details in practical application.It is that to adopt soldering turret main body to be chuck at the bottom of tip be the soldering turret main body being shaped with rotating shaft and attaching nut, and the axle sleeve of the soldering turret main body that is connected is moved in the rotating shaft of tip, and chuck at the bottom of tip is the tip of cross notch.

Summary of the invention

The object of this invention is to provide the welding clamp of the rotatable clamping of a kind of welding rod, realize with the device rotating clamping the problem that the tight and soldering turret of welding rod clamping steady in a long-term generates heat because contact resistance strengthens.

Goal of the invention of the present invention is realized by following technical measures:

The principle of the invention is, in insulation grip, binding post is installed, insulation grip front end connects clamp handle, clamp handle front end connects nose plier with median perpendicular, in nose plier, rotary sleeve is installed, rotary sleeve outer rim there is cutting hole, nose plier outer rim fluting these cutting holes corresponding simultaneously, in nose plier and clamp handle connecting portion inside, rotary sleeve is by front axle and the hinged and connecting strand nose of rear link, clamp handle is installing pressure arm near insulation grip position, and pressure arm rear portion connects pressure handle, and the part of pressure arm in clamp handle connects by drag-line connecting strand nose.

The invention has the beneficial effects as follows: arranging at nose plier place can the rotary sleeve of multi-angle grafting welding rod, reasonable in design, simple for structure, modern design, handling safety is nimble, clamping place Stability Analysis of Structures is solid, and contact is reliable, also can adopt and rotate follow-up adjustment welding rod angle and gripping gesture during use, soldering turret temperature rise is steady, acutely do not generate heat, substantially exempt later maintenance, significant prolongation soldering turret service life.

Accompanying drawing explanation

Fig. 1 is the structural representation in the present invention

Reference numeral:

Insulation grip 1, pressure handle 2, pressure arm 3, dividing plate 4, spring 5, baffle plate 6, drag-line 7, rope nose 8, clamp handle 9, connecting rod 10, front axle 11, nose plier 12, welding rod 13, rotary sleeve 14, bearing 15, binding post 16.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is further described.

As shown in Figure 1, in insulation grip 1, binding post 16 is installed, insulation grip 1 front end connects clamp handle 9, clamp handle 9 front end connects nose plier 12 with median perpendicular, in nose plier 12, rotary sleeve 14 is installed, rotary sleeve 14 outer rim there is cutting hole, nose plier 12 outer rim fluting these cutting holes corresponding simultaneously, in nose plier 12 and clamp handle 9 connecting portion inside, rotary sleeve 14 is hinged and connecting strand nose 8 by front axle 11 and rear link 10, clamp handle 9 is installing pressure arm 3 near insulation grip 1 position, pressure arm 3 rear portion connects pressure handle 2, the part of pressure arm 3 in clamp handle 9 connects by drag-line 7 connecting strand nose 8.

In aforementioned, pressure arm 3 bottom is connected on bearing 15, and bearing 15 is fixed on outside pressure arm 3.

In aforementioned, in clamp handle 9, pressure arm 3 is other installs dividing plate 4, and rope nose 8 is other installs baffle plate 6, and mounting spring 5 between dividing plate 4 and baffle plate 6, spring 5 is socketed in outside drag-line 7.

In the present invention, welding rod 13 cuttage is on the cutting hole in rotary sleeve 14 outer rim, because rotary sleeve 14 can rotate freely, therefore, welding rod 13 angle can conveniently adjust, by hand-held adjustment pressure handle 2 elasticity, strained by drag-line 7 or loosen rotary sleeve 14, making welding rod 13 and nose plier 12 edge hold out against fixing.

Technical scheme of the present invention improve after effect be significant, arranging at nose plier place can the rotary sleeve of multi-angle grafting welding rod, reasonable in design, simple for structure, modern design, handling safety is nimble, and clamping place Stability Analysis of Structures is solid, contact is reliable, also can adopt during use and rotate follow-up adjustment welding rod angle and gripping gesture, soldering turret temperature rise is steady, does not acutely generate heat, substantially later maintenance is exempted, significant prolongation soldering turret service life.

In the present invention, especially, in special welding procedure, can realize manipulating flexible object, in electrode holders front end nose plier 12, be provided with alloy rotary sleeve 14, utilize alloy rotary sleeve 14 and the value difference of clamp handle 9 conductive plate two kinds of different metal resistance, effectively reach thermal resistance effect.After adopting structure of the present invention, when running into welding dead angle, pressing welding rod just can make the angle of welding rod do to change arbitrarily, avoids the problem that the welding of welding dead angle is inconvenient, improves operating efficiency; The iron pipe arranged, avoid and cause scalding the problem of user of service because power cord connector generates heat, also save a large amount of copper products simultaneously, save manufacturing cost, the material of insulation grip 1 insulated handle adopts PVC material to further increase adiabatic effect, structure of the present invention is simple simultaneously, manufactures processing very simple, facilitates processing and manufacturing and use.
