Embodiment

Fig. 1 to Fig. 3 is respectively front view, end view and the vertical view of circuit board element welding jigs and fixtures of the present utility model, this welding jigs and fixtures comprises a clamp body 1, clamp body 1 comprises two sidewalls and a bottom surface at least, is board-like assembly, is used to place the circuit board template; Have a pair of screwed hole that is used to install pin 3 on the clamp body 1 and be symmetrically located at two routine walls, Fig. 2 (sees in preceding 3/4 place that screwed hole is positioned at clamp body 1 two side, at this left end is defined as front end), clamp body has pair of support rods 8 on 1 bottom surface in addition, and support bar 8 is preferably located in preceding 1/4 place of two side.

One template 2 is positioned at clamp body 1 top, supports by support bar 8, and makes itself and clamp body 1 be rotatably connected by pin 3; A pair of anti-drop device 5 connects the both sides central authorities that symmetry is fixed on template 2 by screw, and wherein mousing-hook 504 is in to internal state by the effect of spring 502 all the time.

One pressing plate 4 leans on template 2, Corner Strapped at pressing plate 4 has positioning component 6, pressing plate 4 is correctly located by four positioning components 6, this positioning component 6 is standard components, it comprises linear bearing 602, guide pillar and spring 601, this linear bearing 602 is connected with guide pillar, and spring 601 is set in the guide pillar outside.Belly at pressing plate 4 is provided with a plurality of flexible hold down gags 7, and the length of described flexible hold down gag 7 and quantity are according to circuit board specification and components and parts specification and quantitative requirement making, and is arranged on the pressing plate 4 according to relative position.Be provided with thinner spring 704 in the described flexible hold down gag 7 (as shown in Figure 9); its front end connects a briquetting 702; the front end of briquetting 702 is provided with rubber pressure head 701; components and parts are fitted with circuit board well and play the effect of protection and insulation; end cap 705 is fixed in the rear end of spring 704, is used for when spring 704 is pushed and deformation is taken place it being provided support.

Fig. 5 to Fig. 7 is an embodiment schematic diagram and the corresponding template front view and the end view of the circuit board of special requirement.Irregularly shaped being shaped as of this circuit board, be not limited to shape represented among the figure.Be the shape of common circuit plate equally also, as rectangle.

Fig. 8 is the schematic diagram of anti-drop device, comprises fixed part 501, anticreep pin 503, mousing-hook 504, anticreep spring 502.Mousing-hook 504 can be rotated around pin 503, and mousing-hook 504 bottoms connect with fixed part 501 by spring 502.Anti-drop device 5 is located on the template 2, and sees the middle part that is positioned at clamp body 1 sidewall from side direction.

Operation principle

Inwardly press mousing-hook 504 spring 502 is pressed, thereby take off pressing plate 4.With circuit board shown in Figure 5 template 2 inner chambers (shown in Figure 6) of packing into, insert corresponding components and parts according to technological requirement then, then pressing plate 4 is pressed on the template 2, press mousing-hook 504 once more and make pressing plate 4 fixing getting final product.Because the effect of cramp bar 8 makes template 2 remain on level.

Stir template 2 during welding, template 2 is rotated the service position that finally obtains as shown in Figure 4 by the two ends pin-and-hole around pin 3, thereby can descend the welding procedure in step easily.

Because circuit board overall dimension is approaching relatively, it is more intense that these anchor clamps adaptability just seems.Just can carry out welding operation to most circuit boards on same pair of anchor clamps as long as change the flexible pressure head of template and pressing plate and correspondence, economy is stronger.

Characteristics of the present utility model are: come product is carried out correct the positioning compression finally pin-and-hole by being arranged on the template both sides and the pin manual overturning on the clamp body by prefabricated template and relevant positioning component, flexible pressing device, pressing plate and anti-drop device. Obtaining the position that a template back side makes progress comes components and parts are welded.

The advantages such as the utility model has simple in structure in addition, and is easy to operate, safe and reliable.
