Abstract
The utility model discloses an automatic clamping auxiliary displacement resistance welding tongs, which comprises two mutually connected handles and a chuck positioned at the front end of the handles, wherein a current conducting plate and a plate electrode are arranged on the chuck; the two handles are connected through a rotating pin, and a lifting ring nut is arranged on the rotating pin; the middle part of one handle is provided with a torsion spring which is propped against the inner side of the other handle, and the resilience force of the torsion spring enables the chuck at the end part of the handle to be clamped tightly. The utility model discloses can simplify to the motor coil alternate connection welded technology degree of difficulty, promote production efficiency.
Description
Technical Field
The utility model relates to a resistance welding tongs that is used for automatic centre gripping in high-voltage motor field of making can assist displacement.
Background
After the motor coil is inserted, the coil interphase connecting wire needs to be welded. Because need press from both sides tight soldering turret in the whole welding process, compromise the removal of control soldering turret instrument and welding temperature's control simultaneously, consequently need two welders to mutually support and accomplish the welding process, consume the manpower and comparatively unchangeable, increased the production degree of difficulty. In addition, the handle is hot when the resistance welding tongs are heated for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, provide an automatic resistance welding tongs that displacement can be assisted to centre gripping, it can simplify to the alternate connecting wire welded technology degree of difficulty of electric machine coil, promotes production efficiency.
One technical scheme for achieving the above purpose is as follows: an automatic clamping auxiliary displacement resistance welding tongs comprises two mutually connected handles and a chuck positioned at the front end of the handles, wherein a conductive plate and an electrode plate are arranged on the chuck;
the two handles are connected through a rotating pin, and a lifting ring nut is arranged on the rotating pin;
the middle part of one handle is provided with a torsion spring which is propped against the inner side of the other handle, and the resilience force of the torsion spring enables the chuck at the end part of the handle to be clamped tightly.
Furthermore, a silica gel sleeve is arranged on the holding part of the handle.
Furthermore, the connecting part of the conducting plate and the electrode plate is provided with an insulating gasket.
Furthermore, the middle part of one handle is provided with a torsional spring connecting wing, a connecting hole is formed in the torsional spring connecting wing, and the torsional spring is connected with the connecting wing through a pin shaft.
The utility model discloses an automatic resistance welding tongs that displacement can be assisted to centre gripping increases a torsional spring of installation between the handle, and the during operation manpower is pinched the handle and is made keeping silent and open, loosens the handle torsional spring and extrapolates the handle, and the resilience force of torsional spring presss from both sides tight copper bar, has realized self-holding. The installation eyenut of soldering turret side can be hung the soldering turret and stops in suitable position. The utility model discloses stable performance, it is portable, work efficiency is high, and it is high to maintain convenient security performance, and operating strength is little, and the comfort level is high, low in manufacturing cost, and easy operation sexual valence relative altitude is fit for one-man operation.

fig. 2 is a side view of the automatic clamping displacement-assisted resistance welding tongs of the present invention.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1 and 2, the present invention relates to an automatic clamping auxiliary displacement resistance welding tongs, which is a special tool for welding an inter-phase connection line of a motor coil.
Two handles 1 are connected by a pin shaft 2 made of an aluminum bronze rod in a rotating and pin manner, so that self-lubrication and flexible rotation are ensured in use. Meanwhile, the lifting ring nut 3 is additionally arranged in the middle of the rotating pin, and the resistance welding tongs can be lifted above a workpiece to be welded through the lifting hook during welding, so that the resistance welding tongs can be moved at any time during welding, an operator for assisting welding can be reduced, and single operation can be realized.
The back of the handle is sleeved with a heat-resistant insulating silica gel sleeve 4 to increase the comfort level. Meanwhile, the heat during welding is not transferred to the handle part, people are not provided with contact inductance during welding, and the safety is improved.
The middle part of one handle is provided with a torsion spring mounting wing, and the torsion spring 5 is connected with the pin shaft of the torsion spring mounting wing and props against the middle part of the other handle, so that the welding part of the resistance welding tongs is in a normally closed state. When the welding clamp is used, the resistance welding clamp is opened through manual pressing, the two welded workpieces are automatically clamped by the loosened resistance welding clamp through the spring, and a positive current loop and a negative current loop are formed simultaneously, so that welding is simple, convenient and easy to operate, and manual clamping is not needed.
The handheld part adopts 45 # high strength steel, promotes the durability, and the current conducting plate 5 and the electrode plate 7 of soldering turret front end welding heating part are kept apart with insulation board and insulated column, make to be in insulating state handheld part, the double isolation protection personal safety.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
