The fields such as space flight and aviation are widely applied.Wherein, several different types of joint categories, same metal thin plate are comprised
Connect, the connection of dissimilar metal thin plate and the not connection of uniform thickness sheet metal etc..Sheet metal is connected, the most often occurs
Being exactly the problem on deformation in welding process, and control joint and mother metal deforms within certain limits, most common method is exactly
Use firm, controlled fixture.
High energy beam secondary industry quickly grew in the last few years, and wherein method for laser welding is the most representative, this welding method with
Energy density is high, and heat affected area density is little, welding residual stress and the advantage such as ess-strain is little so that it is be gradually generalized to work
On industry produces.The most this high efficiency welding method is the most gradually applied in the connection of thin-sheet metal.But, owing to swashing
During photocoagulation, LASER SPECKLE is less, and therefore the assembly precision of butt-welding fitting requires high, but high assembly precision means
The time adjusting fixture in commercial production or scientific research and testing is longer.Existing many welding clamping utensil many employings nuts are tight
, once there is deviation or the movement of weld seam relative laser track, it is necessary to sent by all nuts in solid formula in clamping process
Fall, the most not only it is difficult to ensure that clamping precision, also had a strong impact on efficiency.
It addition, in laser beam welding, along with welding object or the difference of operating mode in welding process, need to use tool
Having the eyeglass of different focal, therefore the distance between camera lens from weldment can adjust because focal length is different.But owing to being permitted now
The volume of many design of welding jig is the hugest, and fixture itself has bigger height simultaneously, causes the mirror of some less focal lengths
Sheet cannot use, and causes production or the difficulty of scientific experiment.
Summary of the invention
The technical purpose of the present invention is to overcome the deficiencies in the prior art, it is provided that a kind of fixture being applicable to sheet laser welding,
By using mechanism effectively stainless sheet steel or non-ferrous metal thin to be fixed, and use from lower

Gear is connected, and the lateral symmetry at described one-stage gear arranges secondary gear, connects at the middle part of described secondary gear and supports
Axle, described support shaft contacts through substrate box cover with Z-direction movable plate.
When using, slide clamping sheet metal in the Y direction between fastening plate and Z-direction mobile edition, restraint location
Can be adjusted by slip Y-direction slip fastening plate, to ensure weld seam form and the thrust of multi-form.
One of substrate box house provides the mechanism of vertical lift for Z-direction movable plate, it is ensured that the precision of vertical lift, and adjusts
Whole, easy to maintenance, can reach to dismount rapidly the purpose of standby weldering weldment.By symmetrically arranged adjustment knob, by defeated
Shaft, the first conical gear, the second conical gear, power transmission shaft, one-stage gear, secondary gear and support shaft adjust Z side
Move up and down to movable plate and lock with butt-welding fitting, and the adjustment of sheet metal position can be realized simultaneously.
The clamping device whole height of the present invention is relatively low, and outward appearance is the most flat, it is ensured that different focal camera lens is in use
During not with fixture bump against.Vertical clamping device from bottom to top is additionally used to reach faster thin-sheet metal is entered
The purpose that luggage unloads, greatly reduces clamping and adjusts the time of process.Compared with prior art, the present invention has following
Beneficial effect: (1) significantly reduces fixture height on vertical, it is ensured that the use of the eyeglass of multiple focal range,
Camera lens is avoided to bump against with fixture；(2) decrease the welding early-stage preparations time, improve the efficiency of weldment position adjustment.
