Description
Technical field
The present invention relates to automobile fuel tank end cover field of welding devices, and in particular to be a kind of welding of automobile fuel tank end cover from
Centering special fixture.
Background technology
Automotive oil tank is a very important part on automobile, very strict to its quality requirement, it is ensured that fuel tank was used
Reliability and security in journey.Truck fuel tanks are mostly aluminium alloy fuel tanks, are welded together by oil-box body and two ends end cap
Stroke casing overall structure.
Laser tracking and positioner form, laser tracking are added using welding robot more than end cap of gasoline tank-Circumferential Welds In Cylinders
Device deployment cost is higher, and due to fuel tank part, deviation ratio itself is larger, and general weld jig positioning action is complicated, and positioning is inaccurate
Really, welding efficiency is low, and aluminium alloy is higher to welding process requirement, easily occurs not meeting technical requirements after welding, scraps
Rate is high, and cost wastes big.
To sum up, how to design it is a kind of can effectively solve the not enough automotive oil tank positioning fixture for welding of prior art, become for
One of the problem of those skilled in the art's urgent need to resolve.
The content of the invention
For above-mentioned the deficiencies in the prior art, self-centering exclusive clamps are welded the invention provides a kind of automobile fuel tank end cover
Tool.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of automobile fuel tank end cover welds self-centering special fixture, including bottom plate, the directive slide track machine on bottom plate
Structure, in directive slide track mechanism and along directive slide track mechanism can linear slide end cap locating piece, on bottom plate
Drive mechanism for Driving terminal locating piece along directive slide track mechanism linear slide, the end cap being arranged on bottom plate holds out against face,
And the self-centering hinge being connected with end cap locating piece；The directive slide track mechanism, end cap locating piece and drive mechanism are four
Individual and using bottom plate center as center of circle circumference uniform distribution, the self-centering hinge is two groups and connects two end locating pieces, institute respectively
State two groups of self-centering hinges to be connected with bottom plate center and rotatable by axle of junction, the self-centering hinge and end cap locating piece
Connected by bearing pin and be used to ensure that two end cap locating pieces are equal with bottom plate center spacing when along directive slide track mechanism slips.
Further, the directive slide track mechanism includes two slide rails be arrangeding in parallel.
Further, the end cap locating piece includes location division, is arranged on the installation portion of location division bottom, and connection
In installation portion rear end and for preventing installation portion from skidding off the position-limited box of slide rail；The installation portion is provided with two and slide rail phase
The chute of matching, the end locating piece is arranged on slide rail by chute.
Further, the drive mechanism is cylinder and is arranged between two slide rails, the piston rod of the cylinder
It is connected with installation portion.
Further, the end cap holds out against four support columns that face includes being connected with bottom plate, is connected with four support columns
Disk is held out against, and is arranged on the nylon for holding out against on disk and matching with end cap of gasoline tank and holds out against ring.
Further, the self-centering hinge is connected including center with bottom plate center and around the rotatable middle part in bottom plate center
Connecting rod, two linking arms being connected with middle part connecting rod two ends by bearing pin, two linking arms are positioned with end cap respectively
Block is connected by pin shaft structure, and distance is equal between the junction of described two linking arm two ends, described two linking arms and middle part
Connecting rod junction is equal with middle part connecting rod centre distance.
Further, the middle part connecting rod is additionally provided with bearing with bottom plate center junction.
Compared with prior art, the invention has the advantages that：
(1) in the present invention, middle part connecting rod center is connected with bottom plate center, distance between the junction of two linking arm two ends
Equal, two linking arms are equal with middle part connecting rod centre distance with middle part connecting rod junction, and linking arm connection end cap is determined
Position block, thus the hinged two end cap locating pieces of self-centering be mutually in step linkage and with bottom plate centre distance phase all the time
Deng further two groups of self-centering hinges can navigate to workpiece centre at the center of bottom plate, it is ensured that the accuracy that positions every time and
Uniformity, reduces influence of workpiece itself error to welding, in certain workpiece error range, can cancel welding robot
Laser tracker can also reach welding end cap of gasoline tank required precision, save laser tracker deployment cost；
(2) present invention needs two fixtures to use cooperatively, and end to end during two groups of fixture top tight workpieces, is provided with due to holding out against on disk
Ring is held out against with the nylon that end cap of gasoline tank matches, nylon holds out against ring and the end cap of fuel tank holds out against and can play protection by opposite end lid well
Effect, it is ensured that end cap is not scratched or pushed up bad, and the location division of end cap locating piece need to only clamp end cap, and the action of location division is not
Workpiece can be scratched；
(3) it can change the nylon accordingly matched according to the fuel tank of multiple section size because nylon holds out against ring and hold out against ring,
If the fuel tank of multiple section size, and sectional dimension deviation (is less than 200mm) within the specific limits, only need to change sequence Buddhist nun
Dragon, which holds out against ring, can just realize that welding workpiece is remodeled problem, practical；
(4) middle part connecting rod is provided with bearing with bottom plate center junction, therefore middle part connecting rod rotary resistance is small, and
Rotate flexible, be conveniently adjusted, also save power；
(5) installation portion of end cap locating piece sets position-limited box effectively to prevent installation portion from skidding off slide rail, can also cover in cunning
Rail, it is both beautiful and practical.
