As shown in figure 1, the pressing jig 10 of one embodiment of the invention is used to carry out compression operation to workpiece to be welded.Pressure
Tight tool 10 includes pedestal 100, linear motion platform 200, drive mechanism 300 and compressing member 400.Wherein, linear motion platform
200 are installed on pedestal 100.Drive mechanism 300 is installed on linear motion platform 200, and drive mechanism 300 can be transported along straight line
Moving platform 200 moves along a straight line.Compressing member 400 is installed in drive mechanism 300, linear motion platform 200 and the phase of drive mechanism 300
Mutually coordinate, to drive compressing member 400 to move closer to workpiece to be welded, and compressing member 400 is pressed in workpiece to be welded
On.Compressing member 400 is made up of the material with translucency, and the laser that laser welding head sends can pass through compressing member 400, and to pressure
The workpiece that tight part 400 is compressed is welded.
Compressing member 400 is driven to be compressed workpiece to be welded by using drive mechanism 300, so that workpiece is one
Welded under fixed pressure effect, to overcome the displacement and deformation that are produced in welding process.Meanwhile, pressing jig 10 need not be accounted for
With the space that near workpieces to be welded are larger, you can the compression to workpiece is realized, to be prevented effectively between other processing steps
Movement interference.
It is pointed out that the profile phase of the shape of side that is in contact with workpiece of compressing member 400 and workpiece to be welded
Match somebody with somebody, be brought into close contact with workpiece to be welded, so as to reduce welding deformation amount.For example, the pressing jig 10 of the present embodiment is used to press
Tight VR glasses, the shape of compressing member 400 is to match with the profile of VR glasses.
Specifically, in the present embodiment, compressing member 400 is made up of acrylic material.The laser that laser head is launched can
Through compressing member 400, and heat effect is not produced, so as to be welded to workpiece while compressing member 400 are not influenceed.
Specifically in the present embodiment, drive mechanism 300 includes the first drive component 310 and the second drive component 320.First
Drive component 310 is installed on linear motion platform 200, and the second drive component 320 is installed on the first drive component 310, pressure
Tight part 400 is installed on the first drive component 310.Linear motion platform 200 drives the first drive component 310 to move horizontally, with
The first drive component 310 is set to drive the second drive component 320 and compressing member 400 near workpiece to be welded.First drive component 310
Further drive the second drive component 320 and the horizontal movement of compressing member 400 to workpiece to be welded just to position.Second drives
Component 320 drives compressing member 400 near workpiece to be welded, and compressing member 400 is pressed on workpiece to be welded.
Specifically, the first drive component 310 includes the drive cylinder 312 of support frame 311 and first.Support frame 311 is installed on
On linear motion platform 200, the first drive cylinder 312 is horizontally installed on support frame 311.Second drive component 320 includes peace

Buffer 316 can be abutted with contiguous block 323 away from the side of the second drive cylinder 322, be made with playing buffering to compressing member 400
With preventing compressing member 400 and workpiece from clashing into and defective work piece.
Second drive component 320 also includes the 4th buffer 326, and the 4th buffer 326 is installed on installing plate 321, and
Set near the second drive cylinder 322.When the drive connection block 323 of the second drive cylinder 322 and compressing member 400 are away from workpiece,
4th buffer 326 can be abutted with contiguous block 323 towards the side of the second drive cylinder 322, play slow with to contiguous block 323
Punching is acted on, it is to avoid contiguous block 323 clashes into the second drive cylinder 322.
3rd buffer 316 is engaged with the 4th buffer 326, with the driving stroke to the second drive cylinder 322, namely
The stroke of compressing member 400 is adjusted.
With reference to shown in Fig. 2, Fig. 3 and Fig. 4, specifically in the present embodiment, pressing jig 10 also includes datum plate 500 and regulation
Component 600.Datum plate 500 is located between pedestal 100 and linear motion platform 200, and adjusting part 600 can be to datum plate 500
It is adjusted, so that datum plate 500 is in level.Adjusting part 600 is four, and four adjusting parts 600 are distributed in datum plate
On 500.
Specifically, adjusting part 600 includes height regulation stud 610.Height regulation stud 610 is arranged in datum plate 500,
And be threadedly coupled with datum plate 500.One end of height regulation stud 610 abuts with pedestal 100, rotation height regulation stud 610,
The length that height regulation stud 610 stretches out datum plate 500 changes, so that the distance between datum plate 500 and pedestal 100 change
Become.When pedestal 100 is placed and inclined, multiple height regulation studs 610 are engaged, and can adjust to level datum plate 500, from
And ensureing the holding level of linear motion platform 200 so that drive mechanism 300 moves along a straight line the precise motion of platform 200.Meanwhile,
Multiple collective effects of height regulation stud 610, to form the support of stabilization so that larger pressure can be born on datum plate 500
Power is without failure.
The regulation process of datum plate 500 is realized by threaded adjusting due to height regulation stud 610, and threaded adjusting
Precision can reach 0.01mm so that datum plate 500 obtains the regulation of degree of precision.
In addition, adjusting part 600 also includes positioning stud 620, positioning sleeve 630, axle sleeve 640 and locking stud 650.Pedestal
Location hole (figure is not marked) is offered on 100, axle sleeve 640 is fixedly installed in location hole.Positioning stud 620 is arranged in datum plate
500, and be threadedly coupled with positioning sleeve 630.Positioning sleeve 630 can be placed in axle sleeve 640, so as to datum plate 500 and pedestal
100 are positioned.Screwed hole (figure is not marked) is further opened with pedestal 100, locking stud 650 can be arranged in datum plate 500, and
It is threadedly coupled with screwed hole, to realize the locking of datum plate 500 and pedestal 100.
By setting adjusting part 600, the high accuracy of datum plate 500 can not only be realized by height regulation stud 610
Level tune, and datum plate 500 and base can be realized by being engaged for positioning stud 620, positioning sleeve 630 and axle sleeve 640
Positioning between seat 100, further can also realize that the locking between datum plate 500 and pedestal 100 connects by locking stud 650
Connect.
In above-mentioned pressing jig, compressing member 400 is driven to be compressed workpiece to be welded by using drive mechanism 300,
So that workpiece is welded under certain pressure effect, to overcome the displacement and deformation that are produced in welding process.Meanwhile,
Pressing jig 10 need not take the larger space of near workpieces to be welded, you can realize to the compression of workpiece, be prevented effectively from
Movement interference between other processing steps.
