Technical field

The utility model relates to a kind of laser welder Working piece positioning device.

Background technology

Present sheet laser welding machine is that specification requirement is higher in the Laser Welding field, and its work stage comprises first workbench and second workbench; Be respectively applied for fixing two workpiece to be welded; Two all base of thin plate cut bonding machine slips relatively of workbench, second workbench is step-like, comprises lower first and higher second portion; The first of second workbench can extend into first workbench below, its second portion is concordant with first work stage.At present the location of workpiece is to lean on operating personnel to observe whether aligned of workpiece with eyes on the workbench, and the adjustment of manual movement workpiece compresses workpiece with pressing plate and bolt then by hand.This locate mode location is inaccurate, and is relatively thicker, mainly relies on operating personnel's experience, and each location is all different; Thereby each cutting waste material down is also different, and promptly waste material has at every turn has fewly more, and the workpiece shape after each cutting is also different, owing to locate when cutting inconsistent at every turn; Origin And Destination when causing each the cutting is all inconsistent, and each cutting all will be adjusted the cutting path of laser cutter, and is 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 welding quality unstable.United States Patent (USP) has been announced a kind of workpiece fixed clamping device No. 5098005; But this apparatus structure is complicated; The laser welder Working piece positioning device of the utility model is positioned at the outside of workpiece; So only be fit to the aligning of the straight workpiece of ten minutes standard,, then can't aim at it if the workpiece outer side edges is irregularly shaped.

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.
