Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing:
As shown in Figure 1-3, a kind of friction welding (FW) welds top and top handle welding point, including round end and mobile terminal,
The Clamping Center axis of the rotary shaft of its round end and mobile terminal is point-blank；Round end includes driving flying for round end rotation
Wheel 9, the rolling clamp 6 for clamping center 1 and the top pillar I 10 for stationary center 1, mobile terminal include being used for clamping center
The mobile fixture 4 of handle 3 and top pillar II 12 for stationary center handle 3；Top 1 and the contact surface of top handle 3 are welding surface, two
Welding surface is parallel, and the welding surface of top handle 3 is recessed inwardly to form step cutting pattern hole 7, and solder 2 is movably set in stepped hole 7；Top
Point 1 connects top pillar I 10 by transition piece 5, and transition piece 5 is hollow tubulose；Transition piece 5 is identical as top 1 outer diameter, transition piece 5
Be recessed inwardly the conical socket to be formed and be matched with top 1；Rolling clamp 6 clamps transition piece 5 and top 1 by collet 11.Top
Point 1 is exposed to 6 outside of rolling clamp, and in clamping process, rolling clamp 6 clamps top 1 and makes top 1 some exposing
In rolling clamp 6, make top 1 preferably to contact with solder 2, guarantees welding quality.
Friction welding (FW) welds top and top handle welding point form in the utility model, is welding intermediate solder 2
In journey and postwelding plays the role of buffering, not only avoids because clamping precision error leads to rushing for CONTACT WITH FRICTION initial stage
It hits, and after forge, still there is enough solders 2 in connector, play the mistake for absorbing stress and metallographic structure
The effect of crossing ensure that the final performance of connector meets design and use requirement.And the transition piece 5 by matching with top 1
Booster action increases rolling clamp 6 to top 1 holding area, avoids because top area of bed is small, retaining part has centainly
Pattern draft, holding area it is small, caused by be easy skid the problem of.
7 diameter of stepped hole is more than or equal to the diameter of top 1 welding surface, and multiple concave stations 8 are arranged in the bottom of stepped hole 7.Pass through
The design of stepped hole 7, in stepped hole 7 be arranged solder 2, make intermediate solder 2 in the welding process and postwelding play it is slow
The effect of punching, 7 diameter of stepped hole are greater than the welding surface with 7 opposite side of stepped hole, make weldment during the welding process
Two kinds of weldments are avoided directly to contact, so as to cause brittle crack.
Multiple concave stations 8 include central concave station 81 and the multiple edge concave stations 82 being uniformly arranged around central concave station 81.Edge
There are six concave stations 82, and six edge concave stations 82 are arranged in a ring.Multiple concave stations 8 are uniformly distributed, and make the phase generated in welding process
Varying stress is uniformly spread, and optimizes the performance of joint microstructure, plays the transitional function for absorbing stress and metallographic structure.
In order to improve the quality of welding and the appearance of welding surface, the diameter and thickness of solder 2 is identical as stepped hole 7.
Flywheel 9 is movably set in 6 outside of rolling clamp, and rolling clamp 6 is driven to rotate.Mobile fixture 4 passes through collet 11
Clamping center handle 3 and top pillar II 12.Collet 11 is the tubular structure of sidewall opening, the internal diameter of collet 11 and top 1 outer diameter phase
Together, this design structure keeps top 1 clamping stronger, and the sidewall opening arrangement of collet 11, makes top 1 convenient for picking and placing.
In one embodiment, the retaining part of top handle 3 is recessed inwardly, and step-like, folder is formed with top 3 outer diameter of handle
It holds stronger, prevents from causing due to the interaction of welding surface in the welding process top handle 3 to slide, so as to cause welding
It is of poor quality.
In one embodiment, top 1 hard alloy and structural steel are selected respectively with top handle 3.Solder 2 be pure nickel,
Brass, red copper.It selects pure nickel, brass, red copper as solder, and welds top and top handle welding point in conjunction with friction welding (FW)
Design solves the welding problem of hard alloy and the big material of two kinds of physics, chemical differences of structural steel.
The above is only the preferred embodiment of the utility model only, and the explanation of above example is only intended to help to manage
The method and core concept for solving the utility model, are not intended to limit the utility model, meanwhile, for this field general technology people
