It is soldered to another part, especially in some big parts: as new energy car battery box can not be adopted since part is larger, heavier
Projection welding is carried out with the mode of stationary welding machine, manual handling.Sent automatically using side nut and dynamic lateral electrode binding nut mechanism with
Machine people's activity solves the clamping of dynamic lateral electrode nut, has reached the mode of automatic welding, so as to greatly improve
Production efficiency.Such design reduces part production process, improves productive temp, improves production efficiency, while can pole
The earth reduces production cost, reduces the labor intensity of the producer.
Summary of the invention
Mechanism purpose, be it is larger, heavier in order to solve, particularly solve some heavy parts, can not using fixation it is convex
The mode of welding machine, manual handling carries out projection welding, keeps projection welding automation feasible, liberates the productive forces, improve productive temp, improves production
Efficiency, while production cost can be greatly reduced, reduce the labor intensity of the producer.

Slot, the interior marmon clamp that clamps of annular groove for being respectively embedded into annular gripping sleeve (4) there are two annular fastening spring (1,2) is fixed (4), wherein
Symmetrical two pieces annular gripping sleeves (4) are connected and fixed by screw (12), and the lower end surface of one of annular gripping sleeve (4) is shorter than
Symmetrical another piece of annular gripping sleeve (4), in order that it is fixed (4) to allow welded nut (11) that can enter weld clip from side.Separately
It is parallel plane that the lower part of outer two pieces symmetrical annular gripping sleeves (4), which clamps the end face of welded nut (11), and two planes are
Conductor: when welded nut (11) overcomes annular fastening spring (1,2) power to enter annular gripping sleeve (4) lower boss, marmon clamp
Fixed (4) spreading clamps welded nut (11) under the action of annular fastening spring (1,2) power.Annular steps up to cover the inner wall of (4)
For insulator, the lower part of two movable annular gripping sleeves (4) is respectively kept with boss, and the plane of two boss is parallel plane, and
And two plane be conductor, generated after annular steps up to cover (4) with two nonisulated boss plane contacts when welded nut (11) enter
Circuit is connect with external detection equipment by conducting wire (10), whether in place to determine welded nut (11).
2. an electrode further respectively has cooling cycle water channel (7), stomata (13), annular air channel (8) and straight air flue (9),
And annular air channel (8) runs through with straight air flue (9).(see Fig. 1 and Fig. 2).Cooling cycle water channel (7): cooling cycle can be led to
Water takes away the heat generated when projection welding electrode body (6) projection welding, to achieve the purpose that cooling projection welding electrode body (6), it is ensured that weldering
