A kind of Work fixing device being applicable to laser weld
The present invention relates to auxiliary device for laser welding technical field, be specifically related to a kind of Work fixing device being applicable to laser weld.
Many parts of high pressure vacuum D.C. contactor all adopt stainless steel to be material, and the precise cutting of such parts of stainless steel and welding need adopt Laser Welding to fetch to carry out.In stainless laser beam welding, how the fixing workpiece that need weld is an important problem easily, is also the large factor affecting laser weld effect.The fixed form of welding work pieces had both considered the factors such as workpiece nature and material, also needed the pattern considering welding.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of Work fixing device being applicable to laser weld, the thrust of the high pressure vacuum D.C. contactor workpiece that its adjustable need be welded, thus provide stable, adjustable fixed form for the laser weld of such workpiece, be conducive to the quality and the efficiency that improve welding.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of Work fixing device being applicable to laser weld, it specifically comprises fixture installing plate, clamp base, clamp cylinder, bracket and spacing casting die, fixture installing plate comprises minor axis, clamp cylinder comprises drive link, bracket comprises boss, and spacing casting die comprises fulcrum, laminate end and driving end.
Concrete position relationship and structure:
Bottom minor axis fixture installing plate, can be connected with stepping rotation motor.After connection, according to Laser Welding Speed and other needs, stepping rotation motor can be rotated and controls, thus ensure welding quality.
Clamp base is fixed on above fixture installing plate.
Clamp cylinder is divided into 2, is arranged on bracket both sides symmetrically, and it promotes spacing casting die and compresses workpiece.Drive link is connected with driving end, and its other end is then connected with cylinder block.
Bracket, by being rigidly connected, is fixed on above clamp base.
Boss is arranged on bracket top.
Spacing casting die is divided into 2, is arranged on the both sides of boss symmetrically; The fulcrum of spacing casting die is arranged on bracket, and it, under the promotion of clamp cylinder, moves around fulcrum.
Laminate end is arranged on inside spacing casting die, and the laminate end of both sides can just in the phase pressing of boss top.
Driving end is arranged on the outside of spacing casting die.
In the scheme of further optimization, the clamp base mode be fixed on fixture installing plate is by screw and pin.
After have employed technique scheme, the invention has the beneficial effects as follows:
Relative to the technique for fixing scheme being applicable to high pressure vacuum D.C. contactor laser weld disclosed, originally the Work fixing device being applicable to laser weld has the feature of the thrust of adjustable welding work pieces, thus be conducive to meeting various laser weld requirement, thus improve quality and the efficiency of welding.

Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing 1 and accompanying drawing 2 and specific embodiment, but not as a limitation of the invention.
Be applicable to a Work fixing device for laser weld, be applicable to the welding of high pressure vacuum D.C. contactor workpiece.
Above-mentioned Work fixing device specifically comprises fixture installing plate 1, clamp base 2, clamp cylinder 3, bracket 4 and spacing casting die 5, fixture installing plate 1 comprises minor axis 11, clamp cylinder 3 comprises drive link 31, and bracket 4 comprises boss 41, and spacing casting die 5 comprises fulcrum 51, laminate end 52 and driving end 53.
Bottom minor axis 11 fixture installing plate 1, can be connected with stepping rotation motor.
Clamp base 2 is fixed on above fixture installing plate 1.
Clamp cylinder 3 is divided into 2, is arranged on bracket 4 both sides symmetrically, and it promotes spacing casting die 5 pairs of workpiece 6 and compresses.The thrust of spacing casting die 5 pairs of workpiece is regulated by the pressure in alignment jig cylinder 3.
Drive link 31 is connected with driving end 53.
Bracket 4, by being rigidly connected, is fixed on above clamp base 2.
Boss 41 is arranged on bracket 4 top.
Spacing casting die 5 is divided into 2, is arranged on the both sides of boss 41 symmetrically; Spacing casting die 5, under the promotion of clamp cylinder 3, moves around fulcrum 51.
Fulcrum 51 is arranged on bracket 4.
Laminate end 52 is arranged on inside spacing casting die 5, and the laminate end 52 of both sides can just in the phase pressing of boss 42 top.
Driving end 53 is arranged on the outside of spacing casting die 5.
As shown in Figures 1 and 2, on the basis of above-mentioned embodiment, clamp base 2 mode be fixed on fixture installing plate 1 is by screw and pin.
As shown in Figures 1 and 2, on the basis of above-mentioned embodiment, the embodiment of this Work fixing device can be:
One, welding work pieces 6 is put into 4 li, bracket, promote by clamp cylinder 3 position that spacing casting die 5 compresses the welding of welding work pieces 6 needs.
Two, by the pressure of alignment jig cylinder 3, adjustable welding work pieces 6, the particularly thrust of the welding position of high pressure vacuum D.C. contactor welding work pieces, for laser weld provides a kind of stable, adjustable fixed form.
As known by the technical knowledge, the technical program can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
