Abstract
The utility model discloses an improved fixture for master die capable of more conveniently fixing the circuit board by the operator during the periods of welding the integrated component and various discrete elements. The improved point is to make use of the spring mounted in the spherical nest and the spring washer used to connecting the spherical nest and the sunken screw of the spherical cover. The automatic positioning of the universal handspike is realized; in addition, the centerline intersection angle of the lower clamping plate and the universal handspike are corresponding to the movable angle of the universal handspike, so the clamped circuit plate can arbitrarily alter positions in the spatial dimension of 180 DEG.
Description
The utility model is an improved circuit board clipping, the location of wiring board when being used for welding integrated component and various discrete component on printed substrate.
Existing circuit board clipping mainly is made up of by the universal thick stick of ball ball cup, bulb lid, train wheel bridge, lower plate and an end.The universal thick stick of this circuit board clipping is fixing certain position, is to realize by the fastening means of spiral to universal thick stick lower end ball.Like this, when soldered elements,, promptly change the position of wiring board, at first need loosen spiral, universal thick stick plate to desired location, and then is tightened spiral and could be retightened in the space if need to change the direction of universal thick stick; In addition, the lower plate plane is because vertical with universal thick stick center line, thereby to require printed substrate to change the locus arbitrarily in 180 degree scopes be difficult, though what have can accomplish, but need to adopt other servicing unit, it is too many to cause controlling spiral, uses extremely inconvenient.
Task of the present utility model provides a kind of improved circuit board clipping, makes its folded wiring board can change the position arbitrarily in the spatial dimension of 180 degree, and its universal thick stick can both be located automatically in any desired location.
The utility model is equipped with an obstructed circular hole at the recessed rounded bottom center position of ball cup, in this obstructed circular hole, has laid a spring that is slightly less than its diameter, and spring steel wire is carbon spring steel φ 1.Simultaneously, in each sunk screw (having three herein) that connects ball cup and bulb lid, be lined with a spring washer respectively, like this, the reaction force that lower spring produces universal thick stick lower end ball in the utilization, the automatic location of just having realized universal thick stick.In addition, make universal thick stick center line become miter angle, simultaneously with the lower plate plane, also make the folded central angle of radian sum that is exposed to universal thick stick lower end, bulb lid outside ball become 90 degree, so two angles are echoed mutually, just can make folded wiring board in 180 degree spatial dimensions, change the position arbitrarily.
The utility model is under the situation that does not increase any servicing unit, overcome circuit board clipping in the past can not change angle arbitrarily in 180 degree spatial dimensions deficiency, simplified the fixing program of universal thick stick simultaneously, make the operator more convenient in use, flexibly, and this utility model is simple in structure.
Description of drawings an embodiment of the present utility model.
With reference to Fig. 1, one end is that the universal thick stick (7) of ball is placed between ball cup (1) and the bulb lid (5), by spring (2) and the plain washer (4), the spring washer (6) that fill up in the sunk screw (3) that is connected ball cup (1) and bulb lid (5), come the suitable pressure of co-production, the automatic location of realizing universal thick stick to universal thick stick lower end ball.Rotate wing nut (12), it is poor with respect to the distance of lower plate (10) to adjust train wheel bridge (11), can loosen and clamp wiring board.Between wing nut (12) and train wheel bridge (11), be lined with a plain washer (13).Screw rod (8) relies on round nut (9) that lower plate (10) tightly is pressed on the 45 degree cross sections of universal thick stick with universal thick stick (7) the no relative displacement of combining closely.When rotating wing nut (12), because the reaction of spring (14) and spring (16) can make train wheel bridge (11) approaching to lower plate (10) reposefully.Sunk screw (15) is fixed on the screw plate (17).With reference to Fig. 2, rely on sunk screw (18) that holder (19) and ball cup (1) are connected as one, rotate spanner (22) and make the upper and lower motion of housing screw (20), thereby holder (19) is stuck on the workbench edge securely, and straight pin (21) connects together housing screw (20) and spanner (22).If this circuit board clipping uses on non-standard workbench, can be without holder (19), and directly circuit board clipping is placed on the workbench.
Claims (2)
1, a kind of by ball cup (1), bulb lid (5), train wheel bridge (11), a lower plate (10) and an end are the circuit board clipping that the universal thick stick (7) of ball is formed, and it is characterized in that:
A, be equipped with an obstructed circular hole, in this obstructed circular hole, be equipped with a spring, in connecting the sunk screw (3) that ball cup (1) and bulb cover (5), be lined with a spring washer (6) in the recessed cup dolly centre position of ball cup (1).
B, the same lower plate of described universal thick stick (7) center line (10) plane become miter angle, and the folded central angle of radian sum that is exposed to universal thick stick lower end ball above the bulb lid (5) is 90 degree.
According to the described circuit board clipping of claim 1, it is characterized in that 2, the used steel wire of spring that is put in the obstructed circular hole is carbon spring steel φ 1.
