Description
Technical field
The utility model relates to a kind of technical field of mechanical electric device, specifically a kind of hold down gag for the flat docking laser welding equipment of thin plate.
Background technology
At present, in the flat butt welding termination process of thin plate, mainly adopt human weld, welding efficiency is low, and welding quality is unstable, and postwelding also needs shaping.Along with the development of productivity, the progress of industrial technology, thin plate is put down docking and is adopted Automatic laser to be welded into the effective means improving the quality of production, working environment of enhancing productivity, improve.But the rigidity of thin plate own is poor, poor flatness easily produces buckling deformation, and inevitably produces temperature distortion when welding, and affects Automatic laser welding.Therefore, need to design a kind of hold down gag to support and push down thin plate, make the position of thin plate can not produce skew and the distortion of thin plate can be reduced.
Summary of the invention
The purpose of this utility model is the hold down gag for the flat docking laser welding equipment of thin plate providing a kind of improvement, and it can overcome the easy buckling deformation of plate sheet welding in prior art, affects the some shortcomings of flatness.
To achieve these goals, the technical solution of the utility model is: a kind of hold down gag for the flat docking laser welding equipment of thin plate, it mainly comprises door frame and support platform, it is characterized in that: door frame is provided with crossbeam, the side of crossbeam is provided with one group of liftable hold down gag, hold down gag is made up of oil cylinder, dovetail mount, contiguous block and pressing plate, one end of contiguous block is connected with oil cylinder, the other end is connected with pressing plate by two swing mechanisms, contiguous block is designed to swallow-tail form, and its formation that matches with dovetail mount moves up and down.
During use, made a set of door frame be made up of crossbeam and end-rack, equidistant installation one group of hold down gag on crossbeam, be provided with support platform below door frame, in support platform, plane is guaranteed smooth through machined, guarantees level during installation; During work, thin plate is placed in support platform, moves to assigned address, and the pressure head often overlapping hold down gag declines until effectively compress the thin plate of below.
The utility model has the advantage of that thin plate compresses reliable, prevent that thin plate be shifted, improve the flatness of thin plate itself, in reduction welding process, thin plate is heated buckling deformation amount, and postwelding is without the need to shaping.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of single cover hold down gag in the utility model embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
The label of each accompanying drawing is expressed as follows: 1 oil cylinder, 2 screws, 3 dovetail mounts, 4 contiguous blocks, 5 are had strong market potential, 6 ear seats, 7 short pins, 8 Triangulums, 9 pressing plates, 10 end-rack, 11 crossbeams, 12 hold down gags, 13 support platforms, 14 thin plates.
A kind of hold down gag for the flat docking laser welding equipment of thin plate described in the utility model, it mainly comprises door frame and support platform, its difference with the prior art is: door frame is provided with crossbeam, the side of crossbeam is provided with one group of liftable hold down gag, often overlap hold down gag to be made up of oil cylinder, dovetail mount, contiguous block and pressing plate, one end of contiguous block is connected with oil cylinder, the other end is connected with pressing plate by two swing mechanisms, contiguous block is designed to swallow-tail form, and it matches with dovetail mount and forms linkage from top to bottom campaign.The quantity of hold down gag adjusts according to actual conditions, is generally 4-20.
Be connected by two swing mechanisms between pressing plate with contiguous block, two swing mechanisms are respectively left-right swinging mechanism and swing mechanism.Left-right swinging mechanism is formed by connecting with having strong market potential by ear seat, ear seat by a semicircle shape stake body and be located at one group, stake body two ends step cutting pattern and be formed by connecting, two step cutting patterns are provided with symmetrical front and back through hole, have strong market potential and be arranged in the through hole of front and back, by the connection being formed and can swing of having strong market potential between contiguous block and ear seat, the amplitude of swing is-45 ° ~+45 °.Swing mechanism is formed by connecting by Triangulum and short pin, Triangulum is by base plate and divide the one group of set square being located at base plate both sides to be formed by connecting, the top of two set squares is provided with symmetrical left and right through hole, described short pin is arranged in the through hole of left and right, Triangulum and left-right swinging mechanism are formed by short pin can the connection of swing, and amplitude of fluctuation is-45 ° ~+45 °.
In enforcement, single cover hold down gag course of work is as follows: oil cylinder 1 oil-feed, the piston rod of oil cylinder 1 drives contiguous block 4 to move downward, contiguous block 4 is led by dovetail mount 3 above-below direction and is driven and has strong market potential 5, ear seat 6, short pin 7, Triangulum 8, pressing plate 9 moves downward, until pressing plate 9 workpiece pressing (thin plate), because contiguous block 4 is arranged in the dovetail groove of dovetail mount 3, so the moving direction of contiguous block can control, have strong market potential 5 owing to being provided with simultaneously, ear seat 6, short pin 7 and Triangulum 8, said structure constitutes left-right swinging mechanism and swing mechanism, pressing plate is made to adjust angle, workpiece pressing is controlled with most suitable contact surface, reach best working effect.
Hold down gag in the present embodiment has following characteristics:
The first, adopt the mode that some cover hold down gag multiple spots compress, compress reliable, prevent thin plate local to arch upward injustice;
Second, the lifting of hold down gag and compression adopt hydraulic oil cylinder driving to realize, size is compared with little and thrust is large, thrust size can adjust (by adjustment oil piping system pressure), achieve automatic control, drastically increase the security of production, reliability greatly reduce the labour intensity of workman;
3rd, the oscilaltion of hold down gag has dovetail mount to lead, and cylinder piston rod can be prevented to be subject to side force and leakage of oil or damage;
4th, pressing plate can before and after beat, prevents workpiece fore-and-aft direction uneven and reduce pressing plate contact area, thus pressure is excessive, makes surface of the work occur the defects such as impression;
5th, pressing plate can deflect, and prevent workpiece left and right directions uneven and reduce pressing plate contact area, thus pressure is excessive, makes surface of the work occur the defects such as impression.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that the utility model is specifically implemented to be confined to these explanations above-mentioned.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
