Description
Technical field
The present invention relates to a kind of related equipment for producing composite base cookware, more particularly to a kind of composite base spot welding to press from both sides automatically
Tool.
Background technology
In the production line for making composite base cookware, cookware will be by this procedure of spot welding, cookware, aluminium flake, egative film
Stick together.
In the traditional-handwork mode of production, worker must take out egative film and aluminium flake from egative film heap and aluminium flake heap, be put into dedicated
In fixture, then egative film, aluminium flake are fixed together after closing fixture, are pushed into mash welder, mash welder is controlled by floor push
Egative film, aluminium flake are pre-welded to together.Another worker is transferred to again using another mash welder and another set of special fixture, will be pre-
Egative film, aluminium flake and the pot first welded together positions, is spot-welded together, then opens fixture, checks whether desoldering, then cookware
It is put into down on the conveyer belt of one of instrument.Whole process needs two mash welders and two workers.
This procedure of cookware composite base spot welding is cumbersome, long-term mechanical manipulation, worker can be allowed to produce at work
Fatigue sense, over time, sense tired out increase in geometry level, in darg, more arrive below, and the notice of worker is concentrated
Degree is lower, one slight absent-minded, can produce hardly imaginable security incident.And fixture closes pusher and enters in mash welder not having
Fixed position, the bond pad locations that each pot spot welding comes out are different, and quality disunity will influence the production of subsequent processing.
The content of the invention
The purpose of the present invention is overcome above-mentioned the deficiencies in the prior art, there is provided 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 cookware composite base spot welding, the mash welder includes upper copperhead and lower copperhead, including be split into two halves and for by cookware with
Three workpiece of aluminium flake and egative film tightly surround together and ensure the concentric fixture of three, for opening or close up the fixture
Open-and-close mechanism and buffer gear；Outer contour after the fixture Internal periphery is combined with above three workpiece is consistent；It is described slow
Punch mechanism, open-and-close mechanism, fixture three are from bottom to top set, and form a whole and be installed on the base of the lower copperhead.
Symmetrically it is divided into outer after the Internal periphery that the fixture being split into two halves closes up is combined with cookware, aluminium flake and egative film three
Profile is consistent, so just can guarantee that the fixture after closing up neither is extruded nor rocked with workpiece.
The fixture includes left fixture, right fixture and mold insert；Left fixture and right fixture are symmetrically arranged semicircular structure,
There is semicircle seam allowance in its junction, and it is a full circle not misplaced that both, which close rear outer contour, and the left fixture or right fixture are independent
It is fixed on the mold insert described in one；The mold insert is using mold insert made of iron material matter or stainless steel.Since fixture is general
For the aluminium material being easily worked, the mold insert of iron material matter or stainless steel can prevent fixture to be easily damaged because of being dismounted for multiple times, edge
The addition of part effectively reduces fixture cost of manufacture, improves fixture service life.
The open-and-close mechanism includes open-and-close mechanism base, the cunning being separately positioned on one group of opposite side of open-and-close mechanism base
Rail, the sliding block for being arranged on slide and sliding along, the clamp bottom board being fixed on sliding block；The mold insert is fixed on the fixture
On bottom plate；The first cylinder mounting plate, the first cylinder mounting plate are respectively arranged with described another group of opposite side of open-and-close mechanism base
On be fixed with the first cylinder, the second cylinder is fixed with the piston rod of first cylinder, the piston rod of second cylinder is consolidated
It is scheduled on the clamp bottom board；First tail cylinder, which is equipped with, to be used to pass through precompressed to the cookware and aluminium flake that are put into the fixture
Precompressed distance and the adjusting nut that is adjusted；The clamp bottom board is provided with hollow structure and is used to support the mould of cookware
Core, the lower copperhead are hidden in the core rod hollow space, and the lower copperhead rises rising less than the core rod, the lower copper
Copperhead is on the same line on the center of head and mash welder；The cookware is sleeved on the core rod, cookware inner top surface and core rod
Top surface contacts.The line slide rail pair of slide and sliding block composition has enough rigidity so that always exists when fixture opening and closing left and right
On one linear direction；First cylinder can adjust the stroke of precompressed cookware and aluminium flake by adjusting nut；By cookware pot mouth down
It is sleeved on core rod, aluminium flake is placed at the bottom of a pan, and active force, is added on clamp bottom board, pressed from both sides by the extrapolation of the first cylinder by the second cylinder
Tool bottom plate is slided on slide together with fixture by sliding block, and left fixture, right fixture close up toward centre, due to the first cylinder stroke tune
Section limitation, left and right fixture cannot fully come together, and can only fix cookware and aluminium flake within the specific limits, at this time fixture internal orifice diameter
It is smaller than egative film, egative film is placed on fixture groove, the extrapolation of the second cylinder, left and right fixture will be tightly pressed at together, at this moment cookware,
Aluminium flake and egative film are compacted in concentric relation.
The buffer gear includes buffer gear bottom plate, buffer spring and some guide posts；The buffer gear bottom plate peace
On the mash welder, described guide post one end is fixed on the buffer gear bottom plate, its other end is slided solid by guide sleeve
It is scheduled on the open-and-close mechanism base and the open-and-close mechanism base can slides in vertical direction along guide post；Every guide post overcoat
There is the buffer spring, the buffer spring lower part heads on the buffer gear bottom plate, and its upper part heads on the open-and-close mechanism bottom
Seat；Off working state, buffer spring open, and jack up a whole set of open-and-close mechanism, workpiece and the fixture, and workpiece is separated with lower copperhead；
Working status, the upper copperhead pushes so that buffer spring compression, the upper copperhead, workpiece, lower copperhead mutually touch, and mash welder will
Workpiece sticks together；Upper copperhead rises after spot welding, and the buffer spring rebound, workpiece separates again with lower copperhead.
The medial surface of the fixture semicircular structure is provided with flange, and left fixture closes up rear flange with right fixture and forms a circle
Prevent aluminium flake, egative film from rocking and the encirclement concentric with cookware.
The core rod be equipped be used for detect the cookware whether sensor in place.
It is an advantage of the invention that：The present invention can effectively solve the problems, such as that traditional-handwork production exists, with automatic fixture device generation
For people's clamping apparatus, cooperative mechanical hand and mash welder realize that composite base spot welding automates, and thoroughly mitigate worker's amount of labour, improve production
Efficiency, ensures that weld through product uniformity is good, stable quality；And reduce equipment and number of workers, by original two people, two spot welding
Machine, is reduced to one mash welder of a people.
