Abstract

Disclosed is a pair of energy saving safety welding tongs, mainly composed of an inner guide rod 1, a sleeve barrel 2, a handle 4 and a switch 5. The inner guide rod 1 is arranged in the sleeve barrel 2; the inner side of the sleeve barrel 2 is provided with a spring 7 and a spring adjusting screw 6; the sleeve barrel 2 is arranged on the left end of the handle 4 and is fixed for position by two screw nails 3; the lower part of the handle 4 is provided with the switch 5; the switch 5 is connected with the controlled silicon KP of the primary coil circuit in a welding machine by leading wires; corresponding holes 8 for the insertion of a welding rod are respectively arranged on the inner guide rod 1 and on the cylinder wall of the sleeve barrel 2. The utility model has the advantages of small volume, light weight, raw materials saving, simple structure, easy manufacture, convenient operation, long service life, safety and energy saving.

Description

Energy saving safety welding tongs

The utility model belongs to soldering appliance, a kind of energy-saving safety soldering turret.

The soldering turret of existing electric welding machine adapted is pincerlike spring pressure formula, and volume is big, heavy, complex structure, uses inconveniently, often because of jaw fixes the not firm scaling loss of welding rod, dangerous, very easily scraps.

The purpose of this utility model is in order to overcome the defective that traditional soldering turret exists, therefore to have designed little, in light weight, the easy to use and energy-saving safety soldering turret of a kind of volume.

The utility model is realized as follows:

The energy-saving safety soldering turret, mainly formed by inner guide 1, sleeve 2, handle 4 and switch 5, inner guide 1 is contained in the sleeve 2, spring 7 and spring fixed screw 6 also are housed in sleeve 2, sleeve 2 is contained in the left end of handle 4 and with two screw 3 maintenances, switch 5 is housed below handle 4, and switch 5 is connected with bidirectional triode thyristor KP in being serially connected in the welding machine primary circuit by lead.Be provided with the hole 8 that welding rod is inserted on sleeve 2 barrels, inner guide 1 is provided with a hole 8 that welding rod is inserted.

The utility model has the advantages that: volume is little, in light weight, save raw material, and is esy to use, safe and reliable, and hand switch 5 is in opening and makes controllable silicon KP blocking-up power supply when unloaded, therefore can reach energy-conservation purpose.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is the connection diagram of switch 5 of the present utility model and bidirectional triode thyristor KP and welding machine circuit.

Describe most preferred embodiment of the present utility model with reference to the accompanying drawings in detail:

The energy-saving safety soldering turret, inner guide 1 and sleeve 2 are all made with copper material, the right-hand member of inner guide 1 is provided with a boss and prevents to skid off in order to the interior shoulder place that card ends sleeve 2, handle 4 is to make with insulating materials, screw 3 both had been used for that sleeve 2 and handle 4 were fixed into one and also had been used for tightening simultaneously the soldering turret lead, switch 5 serial connections one two-way controllable silicon KP, bidirectional triode thyristor KP is connected on an end of welding machine circuit primary winding, also can substitute bidirectional triode thyristor with A.C. contactor.This energy-conservation safety welding tong grasps handle 4 in use and makes inner guide 1 touch certain hard thing to press in the sleeve 2, make on hole 8 and sleeve 2 outer walls on the inner guide 1 hole 8 over against and welding rod inserted, discharge inner guide 1 and under the effect of spring 7 elastic restoring forces, the welding rod clamping can be carried out normal welding operation, because work makes switch 5 depress the trigger electrode of connecting bidirectional triode thyristor KP when the time holding handle 4, as connected the magnet coil of contactor when adopting A.C. contactor, switch 5 is in the low current running status, promptly make loaded work piece with the big electric current of little Current Control, when electric welder no-load, switch 5 is in open position, by bidirectional triode thyristor KP blocking-up power supply, make welding machine primary winding no current by promptly reaching no-load automatic stop, thereby avoided unloaded power consumption to reach energy-conservation purpose.Simultaneously also can when changing welding rod or do other back work, avoid taking place soldering turret and workpiece short circuit and produce fully loaded quick-fried lock accident, also reach purpose safe in utilization.

Claims

1, this energy-conservation safety welding tong mainly is made up of inner guide (1), sleeve (2), handle (4) and switch (5), it is characterized in that inner guide (1) is contained in the sleeve (2), spring (7) and spring also are housed in sleeve (2) adjust screw (6), sleeve (2) is contained in the left end of handle (4), with two screws (3) maintenance, in the below of handle (4) switch (5) is housed, switch (5) links by lead and the controllable silicon (KP) that is serially connected in the welding machine primary winding circuit.

2, the energy-saving safety soldering turret described in claim 1 is characterized in that: the inner guide of longitudinal sliding motion (1) upward and on the barrel of sleeve (2) is provided with the corresponding aperture (8) that can insert welding rod respectively only.

3, the energy-saving safety soldering turret described in claim 1 is characterized in that: the controllable silicon (KP) in hand switch (5) the control welding machine primary winding circuit is housed, so as to opening or cut off welding machine primary winding power supply on the handle (4).
