Description
Technical field
The present invention relates to a kind of relevant equipment producing composite base pan, particularly relate to a kind of composite base spot welding and automatically press from both sides
Tool.
Background technology
In the production line making composite base pan, pan will be through this one procedure of spot welding, pan, aluminium flake, egative film
Stick together.
In the traditional-handwork mode of production, workman must take out egative film and aluminium flake from egative film heap and aluminium flake heap, puts into special
In fixture, then after the fixture that closes, egative film, aluminium flake are fixed together, push in mash welder, by foot switch control point welding machine
Egative film, aluminium flake are pre-welded to together.Another workman is transferred to use another mash welder and another set of special fixture again, will be pre-
The egative film that first welds together, aluminium flake and pot position, spot-welded together, then open fixture, check whether sealing-off, then pan
Put into down on the conveyer belt of one instrument.Whole process needs two mash welders and two workmans.
Pan this procedure of composite base spot welding is loaded down with trivial details, and long-term mechanical manipulation can allow workman produce at work
Tired sense, As time goes on, sense tired out is that geometry level increases, and in darg, more to below, the attention of workman is concentrated
Spending the lowest, one slight absent-minded, can produce hardly imaginable security incident.And fixture closes, pusher enters in mash welder not have
Fixing position, each pot of spot welding bond pad locations out is different, and quality disunity will affect the production of subsequent processing.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of composite base spot welding automatic fixture.
The present invention is achieved through the following technical solutions: a kind of composite base spot welding automatic fixture, is arranged on mash welder
On, for pan composite base spot welding, described mash welder includes copperhead and lower copperhead, including be split into two halves and for by pan with
Aluminium flake and three workpiece of egative film are tightly enclosed in together and ensure the concentric fixture of three, for opening or closing up described fixture
Open-and-close mechanism and buffer gear；Outline after described fixture Internal periphery combines with above three workpiece is consistent；Described slow
Punch mechanism, open-and-close mechanism, fixture three are from bottom to top arranged, and on the base being installed on described lower copperhead that forms a whole.
Outside symmetry is divided into after Internal periphery that the fixture being split into two halves closes up and pan, aluminium flake and egative film three combination
Profile is consistent, and the fixture after such guarantee closes up neither extrudes with workpiece and the most do not rocks.
