Description
Technical field
The utility model relates to a kind of device of laser weld field, specifically a kind of frock clamp for printed circuit board heat exchanger laser weld.
Background technology
Printed circuit board heat exchanger (PrintedCircuitHeatExchanger, PCHE) is that a kind of heat transfer property is excellent, high efficiency compact heat exchanger.The different metallic plate of PCHE is first produced by chemical etching and is of a size of 1mm groove runner, be more tentatively fixed into block by laser weld, eventually pass HTHP diffusion bonding and be stacked to whole heat exchanger core closely.If do not have complete matching between each metallic plate of PCHE, there is the position deviation being greater than 0.1mm, this will cause PCHE heat exchanger runner to misplace, and affect the relative position of fluid in heat exchanger, thus destroy the heat exchange between heat exchanger core inner fluid.Because the weld seam of laser weld is very narrow, adjacent two blocks of metal heat-exchange plates all can destroy the connection of weld at any micro gap of weld, and therefore PCHE needs when carrying out laser weld to ensure each metal heat-exchange plate close contact.PCHE laser weld needs special welding tooling to be assisted, this frock needs to meet following three requirements simultaneously: 1) the metal heat-exchange plate close alignment of PCHE, 2) the heat exchanger core after the metal heat-exchange plate of PCHE closely clamps, 3) welding can take out easily from frock.
By finding prior art retrieval, open (bulletin) the day 2013.09.25 of Chinese patent literature CN203209899U, disclose a kind of distributor welding tooling, being intended to distributing pipe in solution prior art is welded on distribution plate by the mode of manual clamping, causes welding operation inconvenience, welds the not high problem of the perpendicularity of rear distributing pipe and distribution plate.It comprises distribution plate, on distribution plate, radial direction offers some through holes, in through hole, one_to_one corresponding is provided with distributing pipe, also include the fixture for clamping distribution plate, fixture comprises upper clamp and lower clamp, lower clamp is provided with to parallel setting with distribution plate weld template, welding template radial direction offers some spliced eyes, and the through hole one_to_one corresponding of spliced eye and distribution plate is arranged.But the prior art can not meet three requirements of PCHE welding tooling, reason is: 1) this distributor welding tooling only has upper lower clamp, not used for alignment and the device of each metal heat-exchange plate of fixing PCHE, can cause PCHE each metal heat-exchange Board position that skew occurs in the process applying clamping force and PCHE is welded when not alignment; 2) this distributor welding tooling applies power by means of only three upper lower clamps to PCHE metal heat-exchange plate local surfaces, cause other surfaces of PCHE metal heat-exchange plate stressed less, make PCHE metal heat-exchange plate surface there is gap because of unbalance stress, thus destroy the bonding strength of laser weld; 3) distribution plate of this distributor frock is greater than PCHE metal heat-exchange plate, causes the molten metal melted during laser weld to be known from experience and is set on the distribution plate of frock, make the PCHE after cannot taking out welding.
Utility model content
The utility model is for prior art above shortcomings, a kind of frock for printed circuit board heat exchanger laser weld is proposed, alignd by alignment pin and secure each metal heat-exchange plate of PCHE, ensureing that position skew does not occur metal heat exchanger plates in welding process; The utility model, by top cover and base clamping PCHE, makes each metal heat-exchange plate close contact in welding process, ensures welding effect; Being ejected by the alignment pin of fixing PCHE by moving back pin screw, making without shearing stress between each metal heat-exchange plate of PCHE, after ensureing welding, the tightness of PCHE is taken out with being convenient to.
The utility model is achieved through the following technical solutions:
The utility model relates to a kind of frock for printed circuit board heat exchanger laser weld, comprise: base, top cover and connect both alignment pin, be arranged at base and top cover four drift angles fastening stud and be positioned at middle part both sides guide rod, wherein: alignment pin vertically runs through the PCHE metal heat-exchange plate of multilayer between base, top cover, be fastenedly connected by stud between top cover and base and by the metal heat-exchange board clamping of centre, be movably equipped with between base, top cover and PCHE metal heat-exchange plate and move back pin screw.
Described base and top cover are rectangular configuration, and size is greater than PCHE metal heat-exchange plate.
Described base and the surrounding of top cover are provided with the welding groove for taking out PCHE.
Described alignment pin be according to GB/T119.2 ?straight pin under the 2000 corresponding nominal diameters chosen, this move back pin screw be according to GB/T65 ?the 2000 socket cap slotted screws chosen.
Described base, top cover and PCHE metal heat-exchange plate are equipped with for locating and fastening through hole.
The described nominal diameter moving back pin screw is less than or equal to the nominal diameter of alignment pin.
The utility model realizes each metal heat-exchange plate of alignment PCHE by the mode of alignment pin.Base is for bearing the metal heat-exchange plate of PCHE, and top cover is for clamping PHCE.Identical locating hole all offered by base, top cover and PCHE metal heat-exchange plate, and alignment pin is for aliging and the relative position of positioning metal heat exchanger plates, base and top cover.
Technique effect
Compared with prior art, the utility model realizes each metal heat-exchange plate of clamping PCHE by the mode of guide rod motion and Stud connection simultaneously.Base and bottom have all been offered the through hole for installing guide rod, base and top cover are twisted by stud in the mode of translation, when also ensure that welding, base and top cover clamp PCHE with relative parallel positions simultaneously, make PCHE uniform stressed in welding process.Top cover and base are clamped by fastening stud, ensure compact siro spinning technology between each metal heat-exchange plate of PCHE, and each metal heat-exchange plate relative offset do not occur in welding process.
The utility model realizes being convenient to take out the PCHE heat exchanger core after welding by moving back pin screw with the mode offering welding groove.Frock top cover offers the screwed hole that diameter is less than locating hole, be opened in two sides of top cover respectively, and screwed hole is coaxial with locating hole.After laser weld, the screwed hole of top cover is screwed on and moves back pin screw, move back pin screw and just alignment pin can be ejected completely each metal heat-exchange plate, so that take out the PCHE metal heat-exchange plate after welding.Carry out laser weld place at PCHE, base and top cover all offer groove, ensure that PCHE solder in welding process can not be bonded in frock, thus are convenient to take out the PCHE metal heat-exchange plate after welding.
