A kind of segmented butt-joint electrodeTechnical field
The present invention relates to machinery manufacturing technology field, particularly a kind of segmented butt-joint electrode.
Background technology
Butt-joint is one conveniently welding manner, and butt-joint can settle the integral solder of parts at one go, and welding effect is good.But the rush of current in butt-joint process is comparatively large, so can be larger for the damage of butt-joint electrode, the service life of butt-joint electrode can be shorter.
Summary of the invention
The technical issues that need to address of the present invention are that the service life of butt-joint electrode in prior art is shorter.
For solving the problems of the technologies described above, the invention provides a kind of segmented butt-joint electrode, comprise electrode body, described electrode body comprises end and shank, end and shank removably connect, shank outboard end is provided with circular hole, in this circular hole, T-shaped plug is installed, tip inside is provided with stepped hole, and aperture, outside is greater than medial aperture, also stepped hole is provided with inside shank, and aperture, outside is less than in medial aperture, outside end, electrode tip is installed, at tip inside, spring is installed, described spring one end connecting electrode head, the step surface of the stepped hole of one end connecting end portion.A kind of segmented butt-joint electrode of the present invention, electrode is set to segmented, comprise end and shank one plug, first distortion allowance change is large in the design of segmented, larger rush of current can be resisted, after being divided into two sections, electrode part damages the part can only changed wherein, does not need integral replacing simultaneously.
Wherein, described end is connected one end outer surface with electrode tip is inclined plane, and by the centre position descending inclination of end face laterally, angle of inclination is 3 °-6 °.End is connected one end outer surface with electrode tip is inclined plane, and consider the magnitude of current that electrode tip produces instantaneously in butt-joint, inclined plane has the effect of transition.
As a further improvement on the present invention, end and shank are threaded connection, and in end, arranged outside has external screw thread, inside shank, be provided with internal thread, external screw thread and internal thread suitable, and be also provided with annular groove between end external screw thread and end bodies.End and shank are threaded connection, convenient and practical, and also annular groove is provided with between end external screw thread and end bodies, annular groove is as the gap between end external screw thread and end bodies, there is regulating action, regulate the change in size brought of expanding with heat and contract with cold.
A kind of segmented butt-joint electrode of the present invention, whole electrode body is divided into end and shank, and be provided with T-shaped plug at shank end, segmented electrodes can resist larger rush of current, non-deformability is stronger, the major part distortion that can effectively avoid expands with heat and contract with cold simultaneously brings, and overall construction design is reasonable, easy to use, effectively extend the service life of electrode.

Detailed description of the invention
The preferred technical solution of the present invention is described in detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of segmented butt-joint electrode of the present invention, comprise electrode body, described electrode body comprises end 1 and shank 2, end 1 and shank 2 removably connect, shank 2 outboard end is provided with circular hole 3, in this circular hole 3, T-shaped plug 4 is installed, stepped hole is provided with inside end 1, and aperture, outside is greater than medial aperture, also stepped hole is provided with inside shank 2, and aperture, outside is less than in medial aperture, electrode tip 5 is installed outside end 1, spring 6 is installed inside end 1, described spring 6 one end connecting electrode head 5, the step surface of the stepped hole of one end connecting end portion 1, described end 1 is connected one end outer surface with electrode tip 5 is inclined plane, and by the centre position descending inclination of end face laterally, angle of inclination is 3 °-6 °, best inclination is 5 °.
Its medial end portions 1 and shank 2 are threaded connection, and in end 1, arranged outside has external screw thread, inside shank 2, be provided with internal thread, external screw thread and internal thread suitable, and be also provided with annular groove 7 between end 1 external screw thread and end 1 main body.
A kind of segmented butt-joint electrode of the present invention, electrode is set to segmented, comprise end and shank one plug, first distortion allowance change is large in the design of segmented, larger rush of current can be resisted, after being divided into two sections, electrode part damages the part can only changed wherein, does not need integral replacing simultaneously.
End is connected one end outer surface with electrode tip is inclined plane, and consider the magnitude of current that electrode tip produces instantaneously in butt-joint, inclined plane has the effect of transition, and generally, the overall angle of end slant surface is 10 °.
End and shank are threaded connection, convenient and practical, and also annular groove is provided with between end external screw thread and end bodies, annular groove is as the gap between end external screw thread and end bodies, there is regulating action, regulate the change in size brought of expanding with heat and contract with cold.
A kind of segmented butt-joint electrode of the present invention, whole electrode body is divided into end and shank, and be provided with T-shaped plug at shank end, segmented electrodes can resist larger rush of current, non-deformability is stronger, the major part distortion that can effectively avoid expands with heat and contract with cold simultaneously brings, and overall construction design is reasonable, easy to use, effectively extend the service life of electrode.
