Description
Technical field
The present invention relates to a kind of weld jig, particularly to a kind of butt welding machine and grip device thereof.
Background technology
Butt welding machine realizes docking and the welding of two workpiece.Dock and weld screw tap and spring steel bar is i.e. that its one should
With.
Standard component manufacturer needs to use high-precision screw tap during manufacturing nut, and this screw tap needs to be welded on
One with on the spring steel bar of 90 degree of bendings of diameter, thus realizes automatic batch tapping, and the axiality of docking requires to be less than
Equal to 0.1mm.
Existing screw tap is welded with two ways with docking of spring steel:
1., after being manually directed at by Simple clamp, the position docked with oxyacetylene torch heating, after reaching certain temperature
Insert copperwelding rod to couple.The shortcoming of this connection: one is that fixture is simple, axiality it cannot be guaranteed that；Two is artificial gas brazing
Welding quality is unstable, needs skilled worker；Three is that the heat affected area of flame is big, can reduce the service life of screw tap.
2. reinforce with welding rod repair welding after being welded by upset butt welder Primary Location or directly positioned by simple fixture
Weld with welding rod afterwards.The shortcoming of this connection be axiality equally it cannot be guaranteed that, after welding rod repair welding, screw tap is in the mistake used
Journey occurs to disconnect at docking point during situation about disconnecting, but the screw tap end fracture near interface, and fracture is irregular,
Secondary reclosing can not be carried out, and when after screw tap arrival in service life, when needing to separate with spring steel, need to cut away a part of bullet
Spring steel, such spring steel is also required to often change.
Therefore, the coaxiality deviation how designing a kind of welded workpiece is little, even if screw tap in use occurs
Also can only disconnect at former faying face during fracture, not affect reusing of spring steel, and weld reliable and stable, simple to operate is right
Welding machine is the purpose of the present invention.

Ultimate range on dish device 19 and the second chuck assembly 23 axis wherein, corresponding first chuck assembly 19 of docking extreme position
With the minimum range on the second chuck assembly 23 axis wherein.
In an illustrated embodiment, rotor 11 is plate-like, when rotor 11 is opening extreme position and docking limit position
When rotating between putting, plate-like rotor drives the first chuck mounting seat 18 and the second chuck mounting seat 22 towards close to each other or mutual
Away from direction move.
In the particular embodiment shown, chuck open-and-close mechanism 9 also includes that one is fixed to rotor 11 to pull rotor
The operation handle 32 of 11, user can make rotor 11 open extreme position and the docking limit by pulling operation handle 32
Rotate between position.
The first alignment pin 14 and the second alignment pin 16, the first alignment pin 14 and the second alignment pin 16 it is fixed with on rotor 11
The diametrically opposite center of rotation in rotor 11 at rotor 11 is symmetrical arranged.Wherein, the first alignment pin 14 is in order to position
The end face of the first workpiece 6 in the first chuck assembly, the second alignment pin 16 is in order to position the end of the second workpiece 8 in the second chuck
Face.When rotor 11 is positioned at and opens extreme position, the first alignment pin 14 and the second alignment pin 16 be positioned at the first chuck assembly and
On the axis of the second chuck assembly.And when rotor is rotated away from opening extreme position, this axis of alignment pin whiz.
Butt welding machine is introduced below from opening the extreme position tool to docking extreme position as a example by welding screw tap and spring steel
Body operating process:
Fig. 1 is butt welding machine equipment screw tap and the structural representation of spring steel state.As it is shown in figure 1, first, handle will be operated
32 counter-clockwise swings are to limit on the right-right-hand limit position (i.e. chuck open-and-close mechanism is positioned at and opens extreme position), the first chuck mounting seat 18 and
Two chuck mounting seats 22 are compressed the compression spring of its correspondence respectively and are synchronized to pull open to both sides；Then screw tap 36 is loaded the first chuck
In 20, its end face is positioned by the first alignment pin 14, and screw tap 36 is clamped by the knob on manual operation the first chuck 20；By spring
Steel 38 loads in the second chuck, and its end face is positioned by the second alignment pin 16, and the knob on manual operation the second chuck 24 is by bullet
Spring steel 38 clamps.
Fig. 2 is the structural representation pasting solder state on screw tap.As in figure 2 it is shown, will operation handle 32 clockwise oscillation
To centre position, the first chuck 20 and the second chuck 24 synchronize to move to centre, and the first alignment pin 14 and the second alignment pin 16 are also
The end face of workpiece to be welded, i.e. screw tap and spring steel is come out by whiz position of center line simultaneously, then at the end face of screw tap 36
On be pasted into solder 40.
Fig. 3 is the structural representation of butt welding machine welded condition.As it is shown on figure 3, continue clockwise oscillation operation handle 32 to
Limit on the left position (i.e. chuck open-and-close mechanism be positioned at docking extreme position), the first chuck 20 and the second chuck 24 continue to synchronize in
Between move, compression spring applies the biasing force making chuck mounting seat relatively close, screw tap 36 He to corresponding chuck mounting seat
Spring steel 38 is abutted together under the flexible bias pressure of compression spring tightly, and abutment end is positioned at the high-frequency induction coil of welding machine
In 4, it is simple to the welding machine welding to workpiece.
Utilizing high-frequency induction welder to carry out welding action after completing above step, after welding, knob of outwarding winding unclamps
One chuck 20 and the second chuck 24, takes out the workpiece after welding, repeats above action, continue welding.
In the above-described embodiments, two chuck assemblies are biased by two biasing devices respectively.At other embodiment
In, can only utilize a biasing device that one of them chuck assembly is biased 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, is i.e. opened by chuck
The rotation closing mechanism only drives this chuck assembly being applied in bias to move.
In sum, the scroll chuck of the docking clamp for special machines part that the present invention provides can part after effective guarantee welding
Axiality, the technique of high-frequency induction brazing can ensure again stable welding effect, and owing to the heat-affected zone of welding is little, collection
In, welding is almost no impact for mother metal (screw tap and spring steel), and solder itself strong added during due to welding
Degree and fusing point are below mother metal, and therefore, during using, screw tap and spring steel only can disconnect, completely at former faying face
Do not affect and repeat welding；When needing separately screw tap after reaching the service life of screw tap, also have only to reheat on fixture
Can easily disconnect from former faying face, the welding again the most not affecting spring steel uses.
Concept described in the invention may be embodied to other form in the case of without departing from its spirit and characteristic.Institute is public
The specific embodiment opened should be considered exemplary rather than restrictive.Therefore, the scope of the present invention is to be wanted by appended right
Ask rather than be determined according to these descriptions before.Any in the letter and equivalency range of claim changes
Become the scope that all should belong to these claim.
