The specific embodiment
As shown in Figure 1, balance bracket in the method for laser welding of balance bracket of the present invention and counterweight lead, comprise main support 7, following main support 9, its both sides between the two are respectively arranged with two side stands 8 that are fixedly connected, be provided with two detents 4 on the outer surface of these 4 side stands 8, it is used for solder side counterweight lead 2, on eight sides of positive anti-communism of side stand 8, and welding side counterweight lead 3.
The method for laser welding of balance bracket of the present invention and counterweight lead, welding used laser both can be continuous laser, also can be pulse laser.
In laser beam welding, weld metal can be vaporized, and has the part metal vapors to be ionized to plasma, and plasma has absorption and scattering process to laser, when the plasma density in weld seam front is intensive, laser is had shielding action.In order to suppress of the shielding action of laser beam welding ionic medium body, dispel the plasma in weld seam front by the side-blown protective gas to laser.Select suitable side-blown protection throughput and side-blown angle, both can dispel the plasma that produces in the welding process, can prevent that again the material in the welding process is oxidized.Welding protection gas can be selected nitrogen, argon gas, helium for use among the present invention, or the mist of argon gas and helium, or other inert gases, as to welding the less demanding of surface quality, also can not apply protection gas.
In the present embodiment, for the welding of balance bracket and counterweight lead, selecting laser instrument for use is solid state laser.Process equipment is five frame-type machining robots, realizes the coordinate operation of laser instrument and machining robot by computer control.
The balance bracket material can be metal and metal alloy, has selected cast titanium alloy ZTC4 in the present embodiment respectively for use, and the 316L stainless steel.The material of face counterweight lead 2 and side counterweight lead 3 is elected pure plumbous Pb4 as.

A: the welding of face counterweight lead
As shown in Figure 2, for the welding of face counterweight lead 2: two detents 4 are arranged in each face of side stand 8, be used to fill out and put face counterweight lead 2.Before the welding, face counterweight lead 2 is packed in the pairing detent 4.In the welding process; need keep vertical with laser beam 5 by solder side; laser beam 5 act on titanium alloy (or: stainless steel) and plumbous at the interface; this interface sealing track run-down of lower edge under robot control; in welding process; protection gas jets 6 applies welding protection gas to weld seam, to prevent the weld seam oxidation.Laser power density 1600W/mm
2(timbering material: cast titanium alloy), 1800W/mm
2(timbering material: stainless steel), sweep speed 20mm/s, laser lens focal length 150mm, defocusing amount is 0, side-blown protection gas 5L/mm, the side-blown angle is 45 °.The face counterweight lead that a is applied on other faces welds.
B: side counterweight lead welding
Operation 1: the 3 positive welding of side counterweight lead, as shown in Figure 3: lay welding special mould clamp 11 in balance bracket 1 both sides, form space 10, side location between the side of side stand 8 and the jig 11.Side counterweight lead 3 is positioned in the space 10, side location, tightens trip bolt 12 then.In the welding process; needing to keep pairing of welding edge; vertical with laser beam 5, robot control laser beam 5 from titanium alloy (or: stainless steel) interface of support side and side counterweight lead 3 is inswept, and applies welding protection gas by protection gas jets 6 to weld seam.Laser power density 1600W/mm
2(timbering material: cast titanium alloy), 1800W/mm
2(timbering material: stainless steel), sweep speed 20mm/s, laser lens focal length 150mm, defocusing amount is 0, side-blown protection gas 5L/mm, the side-blown angle is 45 °.
By above operation 1, side counterweight lead 3 welds with side stand 8.Where necessary, the reverse side that we also can carry out opposite side counterweight lead 3 and side stand 8 again welds, and promptly by operation 2, can increase weld penetration.
Operation 2: side counterweight lead 3 reverse side welding.The jig of guaranteeing to operate in 1 11 has taken off.As shown in Figure 4: with the reverse side of institute's face of weld in the step 1 up, the placement level; Laser beam 5 is vertical with the need solder joint, and is 30 ° of angles with plumb line; Robot control laser beam is inswept from the intersection of balance bracket 1 side and side counterweight lead 3, and applies welding protection gas by protection gas jets 6 to weld seam.Laser power density 1600W/mm
2(timbering material: cast titanium alloy), 1800W/mm
2(timbering material: stainless steel), sweep speed 20mm/s, laser lens focal length 150mm, defocusing amount is 0, side-blown protection gas 5L/mm, the side-blown angle is 45 °.
For the welding of side counterweight lead welding, can only operate 1, promptly weld in the front of an opposite side counterweight lead and balance bracket; Also can after operating 1, operate 2 again, be i.e. after the front of opposite side counterweight lead and the balance bracket welding, again reverse side welded.
B is applied to the welding of other side counterweight leads.
Reliable through balance bracket and connection fusion penetration and intensity between the counterweight lead that above method is welded, overcome in original employing splicing process, adhesive technology randomness is bigger, the unmanageable problem of bonding quality.And because laser energy density height in the welding process, heat input and heat affected area are little, and the deflection of structure is controlled, satisfies instructions for use.
