Abstract
A double-side stirring friction spot welding device comprises a support, a working table, a sliding table and a welding part, wherein the working table is arranged at the lower end of the support; the sliding table is vertically guided on the guide rail of the support; a cylinder is fixed on the support and connected with the sliding table; a cross arm is extended from the sliding table; and the welding part comprises an upper stirring head, a lower stirring head, an upper shaft shoulder and a lower shaft shoulder. The upper stirring head is supported on the cross arm through a bearing; the upper shaft shoulder is sleeved on the upper stirring head; the upper shaft shoulder is supported on the cross arm through the bearing; a motor on the cross arm drives the upper shaft shoulder and the upper stirring head through a gear pair; the lower stirring head is supported on the working table through a bearing; the lower shaft shoulder is sleeved on the lower stirring head; the lower shaft shoulder is supported on the working table through a bearing; and a motor below the working table drives the lower shaft shoulder and the lower stirring head through a gear pair. The upper and lower shaft shoulders have the functions of preventing plastic metal from overflowing, and generating heat through surface friction with the welded parts to compensate a part of the heat. Therefore, the device can avoid deep concave pit of the welding point and large amount of extrusion matters.
Description
Technical field
The utility model relates to a kind of device that is used for two-sided friction stir spot welding.
Background technology
Friction stir welding is that a kind of material solid phase that Britain's institute of welding (The Welding Institute is called for short TWI) proposed in 1991 connects new method, has has meanwhile researched and developed numerous agitating friction soldering equipments.These equipment mainly be welding portion be control one stirring-head with certain pressure-loaded on workpiece to be welded, in rotation, advance with certain speed, so the rotary speed and the translational speed (speed of welding just) of on-load pressure, stirring-head all are the main technologic parameters of friction stir welding along bead direction.Along with further going deep into of friction stir welding technical research, on this technical foundation, friction stir welding spot-welding technology (Friction Stir Spot Welding is called for short FSSW) has been proposed.Stirring friction spot welding technology and the difference of friction stir welding technology are that friction stir spot welding does not move longitudinally along weld seam, and stirring-head does not have (welding direction) inclination angle in pinpoint welding procedure.Therefore the friction stir spot soldering equipment is to realize rotating at a high speed when stirring-head is treated the weldment loading.There is the defective that the solder joint pit is dark, extrudate is many in workpiece after welding with existing friction stir spot soldering equipment.
Summary of the invention
There is the defective that the solder joint pit is dark, extrudate is many in order to solve present friction stir spot soldering equipment, the utility model proposes a kind of two-sided friction stir spot welder.
For this reason, the technical solution of the utility model is: a kind of two-sided friction stir spot welder, constitute by bearing, workbench, slide unit, welding portion, workbench is located at the lower end of bearing, slide unit is vertically-guided on the guide rail of bearing, be fixed with cylinder on the bearing and be connected with slide unit, stretch out transverse arm on the slide unit, it is characterized in that: welding portion comprises stirring-head, descends stirring-head, goes up the shaft shoulder, descends the shaft shoulder; On transverse arm, the last shaft shoulder is enclosed within on the stirring-head last stirring-head by bearings, and the last shaft shoulder on transverse arm, is fixed with motor by bearings on the transverse arm, and motor drives by gear pair and goes up the shaft shoulder and last stirring-head; On workbench, the following shaft shoulder is enclosed within down on the stirring-head following stirring-head by bearings, and the following shaft shoulder on workbench, is fixed with motor on workbench is following by bearings, and motor drives the shaft shoulder and following stirring-head down by gear pair.
Upper and lower stirring-head requires also to realize that except treating weldment exerts pressure rotation at a high speed produces heat with treating the weldment mantle friction, provides welding required heat and power, makes joint form firm connection under the effect of frictional heat.Upper and lower shaft shoulder design can be treated weldment and apply certain pressure and rotation at a high speed around upper and lower stirring-head when welding, its effect mainly is: the one, prevent that plastic metal is excessive; The 2nd, produce heat with treating the weldment mantle friction, compensation realizes the required a part of heat of high-quality welding.Thereby the utility model can be avoided, and the solder joint pit is dark, extrudate defective how.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
A kind of device that is used for two-sided friction stir spot welding as shown in Figure 1, by bearing 1, workbench 10, slide unit 3, thrust bearing 4, bearing 5, motor 8 and gear pair 9, welding portion comprises stirring-head 6, following stirring-head 12 and the last shaft shoulder 7, the following shaft shoulder 11.Last stirring-head 6 is supported on the transverse arm by thrust bearing 4, bearing 5, and the last shaft shoulder 7 is enclosed within on the stirring-head 6, and the last shaft shoulder 7 on transverse arm, is fixed with motor 8 by bearings on the transverse arm, and motor 8 drives by gear pair 9 and goes up the shaft shoulder 7 and last stirring-head 6; On workbench 10, the following shaft shoulder 11 is enclosed within down on the stirring-head 12 following stirring-head 12 by bearings, and the following shaft shoulder 11 on workbench 10, is fixed with motor on the workbench 10 times by bearings, and motor drives the shaft shoulder and following stirring-head down by gear pair.
Described upper and lower shaft shoulder design is around stirring-head, but the plane rotation also can vertically be moved; Can when welding, treat weldment and apply certain pressure.Upper and lower stirring-head to weldment (the be used for welding) span of exerting pressure is: 1470～5880N; The upper and lower shaft shoulder is exerted pressure to weldment, and (be used for heat production and prevent that plastic metal is excessive), value can be smaller, and scope can be decided to be 1000～5000N; Owing to be that spot welding is carried out simultaneously up and down during two-sided friction stir spot welding, and the power that loads is bigger, therefore when welding, require the axiality of stirring-head up and down good.
