The utility model content
The technical problem that the utility model solves is, a kind of laser welder Working piece positioning device is provided, and can guarantee that workpiece accurately locatees, and convenient and reliable operation is beneficial to automated production in enormous quantities.
The technical scheme that the utility model adopts is:
A kind of laser welder Working piece positioning device; Comprise cylinder and the linear bearing that is fixed in the cylinder top; Cylinder and linear bearing are fixed in the second workbench first; Comprise that also the bearing and the bearing that are installed on the cylinder in the linear bearing and are installed on cylinder top can roll around cylinder, through the piston motion of cylinder, the bearing that can make cylinder drive its top descends the location and the welding of motion realization workpiece in vertical direction.
The beneficial effect of the utility model is:
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 laser welder Working piece positioning device of a plurality of parallel arranged can be installed, to be applicable to the workpiece of different size.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment:
Shown in accompanying drawing 1-4, the used laser welder of the utility model comprises base 4, is installed in first workbench 2 and second workbench 5 on the base, and these two workbench 2,5 are respectively applied for fixing thin plate workpiece 3,6 to be welded.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; Second workbench 5 is installed on the accurate length guide rail 9, and accurate straight line short lead rail 8 is installed on second workbench 5, and first workbench 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 moved along guide rail 8,9.Second workbench 5 is step-like, comprises lower first and higher second portion, the first of second workbench 5 can extend into first workbench 2 below, its second portion is concordant with first work stage 2.
Shown in accompanying drawing 1; Laser welder Working piece positioning device 1; Comprise cylinder 12 and the linear bearing 13 that is fixed in the cylinder top; Cylinder 12 and linear bearing 13 are fixed in the lower first of second workbench 5; The bearing 15 and the bearing 15 that also comprise the cylinder 14 that is installed in the linear bearing 13 and be installed on cylinder 14 tops can roll around cylinder 14, and through the piston motion of cylinder 12, the bearing 15 that can make cylinder 14 drive its top descend the location and the welding of motion realization workpiece in vertical direction: the cutting edge of workpiece 3 is resisted against on the bearing 15 so that this workpiece 3 is located; When needs cutting welding; The laser welder Working piece positioning device 1 of the utility model is retracted into downwards in the workbench 5; Travelling table 2, make laser welder Working piece positioning device 1 and workpiece 3 produce horizontal directions relative displacement so that laser welder Working piece positioning device 1 away from the cutting welding edge of workpiece 3.
Also can be provided with a plurality of electromagnet 7 on the workbench 2,5, as shown in Figure 4, can produce attraction with fixation workpiece 3,6 to workpiece after electromagnet 7 energisings.Also be provided with a plurality of vacuum cups 11 on the workbench 2,5, make electromagnet 7 energisings that workpiece is carried out just clamping earlier, when the cutting welding,, do not influence other electronic installation to guarantee electromagnet 7 with cancelling electromagnet 7 behind vacuum cup 11 clamping work pieces.Vacuum cup 11 can be finely tuned on vertical, to compensate the alignment error that is caused by several suckers.The first of second workbench 5 is the laser welder Working piece positioning device of parallel arranged one row's the utility model laterally; Shown in accompanying drawing 4; Be equipped with the laser welder Working piece positioning device 10 of a plurality of the utility model at two cross sides of workbench 2,5, with fixation workpiece 3,6 in a lateral direction.
The utility model in the course of work of sheet laser cutting bonding machine is:
1. second workbench 5 moves to a material loading position laterally, and shown in Figure 4 is the state that second workbench 5 outwards moves to extreme position;
2. (or to be cut) to be welded workpiece 3 is placed on first workbench 2, by laser welder Working piece positioning device 1 location of two the utility model, 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. the laser welder Working piece positioning device 1 of the utility model moves down, and first workbench 2 is driven by servomotor and moves right to preposition, covers the laser welder Working piece positioning device 1 of the utility model;
5. the laser welder Working piece positioning device 10 of workpiece 6 to be welded through the utility model being alignd with the welding edge of workpiece 3 to be welded is close to, and accomplishes 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. to move to the regulation welding position to the inside to be welded for second workbench 5;
8. laser welder is finished workpiece 3 to be welded and 6 butt welding;
9. second workbench 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 accomplished by digital control system control through programming.
