Abstract

The utility model provides a friction stir welding device, which comprises an upper pressing roller and a lower supporting roller. A first workpiece to be welded and a second workpiece to be welded are arranged on the lower supporting roller in parallel. The upper pressing roller presses on the first workpiece to be welded and the second workpiece to be welded. The friction stir welding device further comprises a lateral guide roller and a clamping device. The lateral guide roller is arranged on one side of the first workpiece to be welded far away from the second workpiece to be welded, which is used for lateral location. The clamping device is arranged on one side of the second workpiece to be welded far away from the first workpiece to be welded. The position of the clamping device is controlled according to the width of the workpiece to be welded so as to make the workpiece to be welded throughout next to one side of the lateral guide roller. The position of the clamping device is controllable, thus the width of the workpiece to be welded is free from the limitation of the structure of the friction stir welding device. Therefore, the workpiece wide in amplitude surface can be welded.

Description

A kind of agitating friction welder
Technical field
The utility model relates to welding technology field, relates in particular to a kind of agitating friction welder.
Background technology
Since Britain's institute of welding in 1991 since (The Welding Institute-TWI) invented friction stir welding (Friction Stir Welding-FSW); because application that it had and plurality of advantages economically; such as smooth welded seam; need not wlding; weldment stress is little; the welding wide ranges; welding procedure is easy to hold; welding cost is low etc.; make friction stir welding reach scale in the manufacturing field; industrialized application level, and in shipbuilding; rail vehicle is made; world's aerospace is made; proud achievement has all been obtained in fields such as world car industry.
Along with the increasingly extensive application of friction stir welding, people constantly study improvement at its technological parameter and stirring-head vpg connection, but but the structures shape of agitating friction welding equipment itself width of its welder's part.Major part is that workpiece to be welded is fixed on the platen in the existing agitating friction welding equipment, rely on the feed motion of the motion realization workpiece of platen or machine tool chief axis, thereby the welding process of finishing, the weld width of this welder's part with regard to making is subjected to the restriction of machine tool travel, thereby can't realize the welding of wide format workpiece.
The utility model content
Problem to be solved in the utility model provides a kind of agitating friction welder, makes the width of workpiece to be welded not be subjected to the restriction of this body structure of agitating friction welding equipment, thereby realizes the welding of wide format workpiece.
The technical solution of the utility model is:
A kind of agitating friction welder, comprise pressure roller and snub pulley, first workpiece to be welded and second workpiece to be welded place on the described snub pulley side by side, the described pressure roller of going up is pressed on described first workpiece to be welded and second workpiece to be welded, also comprise side guide wheel and hold down gag, described side guide wheel be positioned at first workpiece to be welded and second workpiece to be welded away from a side, be used for lateral register, described hold down gag be positioned at second workpiece to be welded and first workpiece to be welded away from a side, according to the position of the width adjusting hold down gag of workpiece to be welded workpiece to be welded is close to all the time to side guide wheel one side.
The utility model agitating friction welder, its position is adjusted according to the width of workpiece to be welded in good time, workpiece to be welded piece together and after width unrestricted, can realize the welding of wide format workpiece.
Description of drawings
Fig. 1 is the utility model agitating friction welder embodiment schematic diagram.
The specific embodiment
The utility model agitating friction welder adopts the lateral register technology, and the position according to the width timely adjustment clamping cylinder of workpiece to be welded is close to workpiece to be welded all the time, thereby welding process is steadily carried out to side guide wheel one side that is used for lateral register.
Below in conjunction with accompanying drawing specific embodiment of the utility model is done detailed elaboration.
Agitating friction welder of the present utility model, as Fig. 1, comprise pressure roller, snub pulley, side guide wheel 1, side pressure bearing up pulley 5 and clamping cylinder 4 (not shown pressure roller and the snub pulley gone up), side pressure bearing up pulley 5 comprises support 51, clamping cylinder 4 comprises piston rod 41, first workpiece 2 to be welded and second workpiece 6 to be welded place on the snub pulley side by side, last pressure roller is pressed on first workpiece 2 to be welded and second workpiece 6 to be welded, side guide wheel 1 be positioned at first workpiece 2 to be welded and second workpiece 6 to be welded away from a side, described side pressure bearing up pulley 5 be positioned at second workpiece 6 to be welded and first workpiece 2 to be welded away from a side, clamping cylinder 4 is positioned at the opposite side of side pressure bearing up pulley 5, the support 51 of side pressure bearing up pulley adopts hinge to be connected with the piston rod of clamping cylinder 4 41, position according to the width adjusting clamping cylinder 4 of workpiece to be welded, cylinder 4 is fixed on the suitable spacing hole by locking part (screw or pin etc. all can), make side pressure bearing up pulley 5 flexibilities compress workpiece to be welded, last pressure roller presses down, after stirring-head is aimed at welding bead 3, the stirring-head of rotation presses down, mixing needle slowly enter workpiece until mixing needle backgauge shoulder with till workpiece contacts, workpiece is under the drive of tractive force, along welding direction march forward to, workpiece is close to the side guide wheel 1 that is used for lateral register all the time in the whole welding process because the effect of clamping cylinder makes, and welding process is steadily carried out.
Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
