Abstract
The present invention relates toa sheet laser cutting-welding machine. It includes laser cutting-welding machine, base seat, working table mounted on the base seat, said working table is used for fixing sheet workpiece. On the working table at least two positioning pin which are parallel and can be upward and downward stretched out and drawn back are set, the cutting edge of said workpiece is placed against the described positioning pins so as to make said workpiece be positioned. When the sheet has need of cutting and welding, the positioning pins can be downward drawn into working table, so that said positioning pins can be far separated from the cutting-welding edge of workpiece.
Description
Technical field
The present invention relates to a kind of sheet laser cutting bonding machine, relate in particular to a kind of sheet laser cutting bonding machine that has precision positioning device.
Background technology
The location of workpiece is to observe workpiece by operating personnel with eyes whether to aim at the location on the existing sheet laser cutting bonding machine workbench, and manual travelling workpiece adjustment compresses workpiece by hand with pressing plate and bolt then.This locate mode location is inaccurate, and is relatively thicker, mainly relies on operating personnel's experience, each location is all different, thereby each cutting waste material down is also different, and promptly more waste material has to have at every turn and lack, workpiece shape after each cutting is also different, because the location is inconsistent during each the cutting, the Origin And Destination when causing each the cutting is all inconsistent, and each cutting all will be adjusted the cutting path of laser cutter, pretty troublesome, the time of auxiliary adjustment work is long, inefficiency, the incompatible production in enormous quantities in enormous quantities.Because clamping mode is undesirable, cause the local warpage of workpiece in addition, influence weldquality, cause the welding quality instability.
It is the special fixture that designs for numerical control fully-automatic laser weldering platinum alloy bushing that Chinese patent application has disclosed for No. 91230556 a kind of, mainly form by top board and clamp body, and be provided with support muscle, groove and dowel hole etc. in the above, to reach fast, accurately to locate, guarantee to have good flatness and good welds quality.The alignment pin of these anchor clamps and the alignment pin of bushing all are by artificial location, and by bolted, efficient is not high, and are not suitable for thin plate cutting and welding.
United States Patent (USP) has also disclosed two kinds of workpiece fixed clamping devices that are used for laser-beam welding machine for No. 5098005 and No. 5045668, but these apparatus structure complexity.The alignment pin that No. 5045668 patent disclosed is positioned at the outside of workpiece, so only be fit to the aligning of the straight workpiece of ten minutes standard, if the workpiece outer side edges is irregularly shaped, then can't aim at it.Workpiece fixed clamping device in the laser-beam welding machine that United States Patent (USP) is disclosed for No. 5023427 adopts the electromagnetism suction means, in use can disturb other electronic installation.
Summary of the invention
The object of the present invention is to provide a kind of workpiece that guarantees accurately to locate, convenient and reliable operation, the sheet laser that is beneficial to automated production in enormous quantities cuts bonding machine.
The objective of the invention is to realize by following technical method: sheet laser cutting bonding machine comprises the laser cutting bonding machine, base, be installed in the workbench on the base, this workbench is used for fixing the thin plate workpiece, be provided with at least two parallel alignment pins that can stretch up and down on workbench, the cutting edge of workpiece is resisted against on the described alignment pin so that this workpiece location; When needs when welding cutting, alignment pin is retracted into downwards in the workbench, alignment pin with workpiece generation relative displacement so that alignment pin away from the cutting welding edge of workpiece.
Sheet laser cutting bonding machine disclosed in this invention, its advantage shows: the accurate work piece positioning that is cut and welds is reliable, fast, has improved production efficiency greatly, improves cutting and welding quality, and what help producing is automated and semi-automatic.And the alignment pin of a plurality of parallel arranged can be installed, to be applicable to the location of different size workpiece.

The specific embodiment
Below in conjunction with embodiment the present invention is further described.
See also Fig. 1 to Fig. 4, sheet laser cutting bonding machine of the present invention comprises laser cutting bonding machine, base 4, is installed in upper table 2 and lower table 5 on the base, and these two workbench 2,5 are respectively applied for splint fixation workpiece 3,6.Precision ball screw (not shown) is installed on the base 4, accurate line slideway 8,9 links to each other with above-mentioned leading screw, lower table 5 is installed on the accurate length guide rail 9, and accurate straight line short lead rail 8 is installed on the lower table 5, and upper table 2 is installed on the accurate straight line short lead rail 8.Drive precision ball screw by digital control system control servomotor and rotate, and then workbench 2,5 can be slided along guide rail 8,9.
Lower table 5 comprises two parts, wherein first can extend into upper table 2 below, another part is concordant with upper table 2, a horizontal row is arranged in the first of lower table 5 to the alignment pin 1 of parallel arranged.Alignment pin 1 comprises cylinder 12, is fixed in the linear bearing 13 of cylinder top, be installed on the cylinder 14 in the linear bearing 13 and be installed on the bearing 15 of cylinder 14 tops, and bearing 15 can rotate around cylinder 14.By the piston motion of cylinder 12, can make cylinder 14 drive bearing 15 and move in vertical direction.The cutting edge of workpiece 3 is resisted against on the bearing 15 of alignment pin 1 so that these workpiece 3 location; When needs when welding cutting, alignment pin 1 is retracted into downwards in the workbench 5, travelling table 2, make alignment pin 1 and workpiece 3 produce horizontal directions relative displacement so that alignment pin 1 away from the cutting welding edge of workpiece 3.
The course of work of sheet laser cutting bonding machine of the present invention is:
1. lower table 5 moves to a material loading position laterally, Figure 2 shows that lower table 5 outwards moves to the state of extreme position;
2. (or to be cut) to be welded workpiece 3 is placed on upper table 2, by two alignment pins, 1 location, is undertaken just clamping by two in the electromagnet 7 workpiece 3 to be welded immediately;
3. vacuum cup 11 work sucks clamping with workpiece 3 to be welded, electromagnet 7 dead electricity immediately, and the electromagnetism clamping force disappears;
4. alignment pin 1 moves down, and upper table 2 is driven by servomotor and moves right to preposition, covers alignment pin 1;
5. workpiece 6 to be welded being alignd with the welding edge of workpiece 3 to be welded by alignment pin 10 is close to, and finishes the location of two workpiece to be welded, immediately by in the electromagnet 7 effective two electricly just clamp;
6. vacuum cup group 11 work suck clamping with workpiece 6 to be welded, and electromagnet 7 dead electricity are unclamped immediately;
7. it is to be welded that lower table 5 moves to the regulation welding position to the inside;
8. laser welder is finished workpiece 3 to be welded and 6 butt welding;
9. lower table 5 moves to the blanking position of regulation laterally;
10. vacuum cup group 11 quits work, and clamping force disappears;
11. the workpiece after will welding takes off from workbench.
Above process can be finished by digital control system control by programming.
The advantage of thin-plate laser cutting-welding machine of the present invention is: the accurate work piece positioning that is cut and welds Reliably, fast, greatly improved production efficiency, improved cutting and welding quality, be conducive to produce Automated and semi-automatic. And because the alignment pin of a plurality of parallel arranged has been installed, applicable to difference The workpiece of specification.
