Description
Technical field
The utility model relates to a kind of microwave circuit weld jig.
Background technology
In microwave device, need sometimes the unsettled placement of circuit wafer, need be welded on the cavity inner wall around the circuit wafer.For making convenient welding, guarantee that welding is smooth.At present, known method one of cushioning below circuit wafer welds after that it(?) again will circuit wafer flattening with big metal platforms such as cavity inner chambers.The method is inhomogeneous, stressed because of the scolder consumption easily in the circuit wafer welding process, be heated unequal and cause circuit wafer deformation, and is high to the little flat requirement of welding personnel technology.And in the cooling procedure after having welded, because stress, inhomogeneous cooling etc. also are easy to cause the circuit wafer distortion, and welding quality is difficult for guaranteeing.Influence the microwave property of device.
The utility model content
The utility model discloses a kind of microwave circuit weld jig, this weld jig can not only well reduce the distortion after the circuit wafer welding, and clamping is simple, and convenient welding is easily gone.
In order to achieve the above object, the technical solution adopted in the utility model is: these anchor clamps are made up of base, briquetting, housing screw, support four parts, and base end face smoothly offers the twice parallel groove on it, form a raised platforms between two grooves;
Housing screw head and root are threaded, and stage casing column part diameter is less than the thread root circular diameter, and the housing screw head is processed into sphere;
Support is fixed on the base, is provided with screwed hole over against the raised platforms place on it, and housing screw passes the screwed hole root and the support upper screwed hole is fixed;
Briquetting is chrome faced stainless steel material, and its bottom surface is smooth, and crown center is provided with screwed hole, the side has groove or the hole is communicated with the screwed hole bottom, the middle place of edge is thin, and overall dimensions is pressed on raised platforms by housing screw less than the raised platforms size.
The beneficial effects of the utility model are: can better reduce the deformation after circuit wafer welds, guarantee welding quality, and clamping be controlled, welding operation is convenient and easy, and volume is little, and is simple in structure.

The specific embodiment
For those skilled in the art are more readily understood, below in conjunction with the specific embodiment the utility model is done to be described in more detail.
Consult Fig. 1 to Fig. 6, a kind of microwave circuit weld jig, these anchor clamps are made up of base 1, briquetting 2, housing screw 4, support 3 four parts, and base 1 bottom surface smoothly offers 12 formation of twice parallel groove 12, two grooves, one raised platforms 13 on it.Housing screw 4 heads and root are threaded, and stage casing column part diameter is less than the thread root circular diameter.Housing screw 4 heads are processed into sphere.Support 3 is fixed on the base 1, is provided with screwed hole 14 over against raised platforms 13 places on it, and housing screw 4 passes screwed hole 14 roots and support 3 upper screwed holes 14 are fixing.Briquetting 2 is chrome faced stainless steel material, and its bottom surface is smooth, and crown center is provided with screwed hole 8, the side has groove or hole 10 is communicated with screwed hole 8 bottoms, the middle place of edge is thin, and overall dimensions is pressed on raised platforms 14 by housing screw 4 less than raised platforms 14 sizes.
During use, microwave cavity 6 is inserted in raised land 14 on the base 1, again circuit wafer 5 is put in the position to be welded in the cavity, support 3 is fixed on the base 1, have chute 11 on the base 1 and can be used for adjusting briquetting 2 positions with sunk screw 7.Housing screw 4 passes the screwed hole 14 of support 3 tops, its root screw thread cooperates with support 3 screwed holes 14, head threads is partly passed and is entered in briquetting 2 grooves or the hole 10 behind the screwed hole 8 on the briquetting 2, form the structure that a kind of housing screw 4 could freely rotate and don't can deviate from briquetting 2, tighten housing screw 4 and flatten circuit wafer 5 fixing.The length of the height of its medium-height trestle 3 and housing screw 4 should guarantee that the stroke L of briquetting 2 should be greater than the height overall H of microwave cavity 6, putting into and taking out with instant microwave cavity 6.Then after being heated to welding temperature on the hot platform, gap location is inserted welding wire and is welded around the briquetting 2, and after having welded, with the same cavity of anchor clamps, circuit wafer takes off together, unclamps anchor clamps after cooling again.In whole welding process and cooling procedure, circuit wafer 5 is in the state that is driven plain all the time, thereby has well guaranteed the flatness after the circuit wafer welding.
In addition, physical dimension a, the b in the groove of briquetting 2 or hole 10 should be respectively greater than physical dimension c, the d of housing screw 4 sphere shape heads.Raised land 13 on the base 1 adopts 0.05～0.1mm matched in clearance all around and between microwave cavity 6 internal chamber walls; The gap is 1mm around the briquetting 2 and between microwave cavity 6 internal chamber walls, and it is the 0.4mm welding wire that welding wire adopts diameter.Wherein briquetting 2 materials are stainless steel, and chrome-faced is handled, and make it be difficult for being welded by scolder.Housing screw 4 materials are stainless steel, and base 1 and support 3 materials are duralumin.
