Chuck open-and-close mechanism 9, comprises the rotor 11 being connected to board 2 rotationally, and at least one of them is connected for rotor 11 and the first chuck assembly and the second chuck assembly.In the particular embodiment shown, chuck open-and-close mechanism 9 is connected with the first chuck mount pad 18 and the second chuck mount pad 22, is configured to drive the first chuck mount pad 18 and the second chuck mount pad 22 to open between extreme position and a docking extreme position one and moves.
In an illustrated embodiment, rotor 11 can this open extreme position and docking extreme position between rotate, do above-mentioned relative movement to drive the first chuck assembly 19 and the second chuck assembly 23.Wherein, open corresponding first chuck assembly 19 of extreme position and the second chuck assembly 23 ultimate range wherein on axis, corresponding first chuck assembly 19 of docking extreme position and the second chuck assembly 23 minimum range wherein on axis.
In an illustrated embodiment, rotor 11 is plate-like, when rotor 11 open rotate between extreme position and docking extreme position time, plate-like rotor drive the first chuck mount pad 18 and the second chuck mount pad 22 towards close to each other or mutually away from direction move.
In the particular embodiment shown, chuck open-and-close mechanism 9 also comprises one and is fixed to rotor 11 to pull the operating grip 32 of rotor 11, user by pull operating grip 32 make rotor 11 open extreme position and docking extreme position between rotate.
Rotor 11 is fixed with the first alignment pin 14 and the second alignment pin 16, first alignment pin 14 and the second alignment pin 16 to be symmetrical arranged relative to the pivot of rotor 11 in the radial direction of rotor 11.Wherein, the first alignment pin 14 is in order to locate the end face of the first workpiece 6 in the first chuck assembly, and the second alignment pin 16 is in order to locate the end face of the second workpiece 8 in the second chuck.When rotor 11 be positioned at open extreme position time, the first alignment pin 14 and the second alignment pin 16 are positioned on the axis of the first chuck assembly and the second chuck assembly.And when rotor rotate leave open extreme position time, this axis of alignment pin whiz.
Butt welding machine is introduced from opening the concrete operations flow process of extreme position to docking extreme position below to weld screw tap and spring steel:
Fig. 1 is the structural representation of butt welding machine equipment screw tap and spring steel state.As shown in Figure 1, first, by operating grip 32 counter-clockwise swing to limit on the right-right-hand limit position (namely chuck open-and-close mechanism is positioned at and opens extreme position), the Compress Spring that the first chuck mount pad 18 and the second chuck mount pad 22 compress its correspondence respectively synchronously pulls open to both sides; Then loaded by screw tap 36 in first chuck 20, its end face is located by the first alignment pin 14, and screw tap 36 clamps by the knob on manual operation first chuck 20; Loaded by spring steel 38 in second chuck, its end face is located by the second alignment pin 16, and spring steel 38 clamps by the knob on manual operation second chuck 24.
Fig. 2 is the structural representation pasting solder state on screw tap.As shown in Figure 2, by operating grip 32 clockwise oscillation to centre position, first chuck 20 and the second chuck 24 synchronously move to centre, first alignment pin 14 and the second alignment pin 16 also simultaneously whiz position of center line by workpiece to be welded, namely the end face of screw tap and spring steel comes out, and then on the end face of screw tap 36, is pasted into solder 40.
Fig. 3 is the structural representation of butt welding machine welded condition.As shown in Figure 3, continue clockwise oscillation operating grip 32 to limit on the left position (namely chuck open-and-close mechanism is positioned at docking extreme position), first chuck 20 and the second chuck 24 continue synchronously to move to centre, Compress Spring applies the biasing force making chuck mount pad relatively close to the chuck mount pad of correspondence, screw tap 36 and spring steel 38 are abutted together tightly under the flexible bias pressure of Compress Spring, and abutment end is positioned at the high-frequency induction coil 4 of welding machine, be convenient to the welding of welding machine to workpiece.
Utilize high-frequency induction welder to carry out welding action after completing above step, after welding, knob of outwarding winding unclamps the first chuck 20 and the second chuck 24, is taken out by the workpiece after welding, repeats above action, continues welding.
In the above-described embodiments, two biasing devices apply bias voltage to two chuck assemblies respectively.In other embodiments, can only utilize a biasing device to apply bias voltage to one of them chuck assembly to another chuck assembly, and another chuck assembly is fixed on board.Chuck open-and-close mechanism is then only connected with the chuck assembly being applied in bias voltage, namely only drives this chuck assembly being applied in bias voltage to move by the rotation of chuck open-and-close mechanism.
In sum, the scroll chuck of docking clamp for special machines part provided by the invention can the axiality of part after effective guarantee welding, the technique of high-frequency induction brazing can ensure stable welding effect again, and due to welding heat-affected zone little, concentrate, weld for mother metal (screw tap and spring steel) almost without any impact, and the intensity of the solder added during owing to welding itself and fusing point are all lower than mother metal, therefore, in the process used, screw tap and spring steel only can disconnect from former faying face, do not affect repeat welding completely; When needing after reaching the service life of screw tap to separate screw tap, also only need to reheat on fixture and can easily disconnect from former faying face, the welding again not affecting spring steel completely uses.
Concept described in the invention may be embodied to other form when not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary instead of restrictive.Therefore, scope of the present invention is by appended claim, instead of determines according to these descriptions before.Any change in the letter and equivalency range of claim all should belong to the scope of these claims.
