The specific embodiment
Followingly describe embodiment of the present utility model in detail with reference to accompanying drawing.
As shown in Figure 1, be provided with printed circuit board (PCB) (PCB) workbench 5 in the printed circuit board (PCB) drilling machine, workbench 5 is provided with at least one parking position groove (3 parking position grooves exemplarily are shown among Fig. 1), is respectively arranged with the printed circuit board (PCB) clamping device in the parking position groove.
F that indicates among Fig. 1 and B represent the place ahead and the rear of workbench respectively, and alleged hereinafter left side and right side are according to deciding in the face of workbench the place ahead F observes workbench.Forward and backward alignment pin on the printed circuit board (PCB) S is represented with FP, BP respectively.
The utility model printed circuit board (PCB) clamping device comprises base plate (being workbench 5), and it is provided with at least two grooves; At least two clamp mechanism independently, it is arranged at respectively in this groove, and comprises fixed head and movable plate respectively, and each movable plate moves under cylinder action respectively, is clamping between this fixed head and the movable plate or is unclamping alignment pin on this printed circuit board (PCB); This clamp mechanism is the reinforcement clamp mechanism, when clamped condition, the alignment pin of clamping is applied the active force of increase.
Parts such as the cylinder 1 during exemplary printed circuit board (PCB) clamping device is shown by Fig. 1, arm-tie 2, fixed head 3, big movable plate 4, pin III6, rocking arm 7, pin II9, pin I8, little pin 10, little movable plate 11, backing plate 12, little fixed head 13, connecting rod 14, connecting pin 16, cylinder 15 and screw are formed.
Use after annexation between each parts and the assembling now is specified in down:
The exemplary clamping device of the utility model comprises independently prelocalization pin clamp mechanism and back alignment pin clamp mechanism.Prelocalization pin clamp mechanism comprises the backing plate 12 that is installed in the sulculus of workbench front, be vertically fixed on the little fixed head 13 on the backing plate, the little pin 10 of one end band screw also is vertically fixed on the backing plate 12, little pin 10 is equipped with in the hole of little movable plate 11 left ends, and little movable plate 11 can be around little pin 10 rotations.Connecting rod 14 is connected in the horizontal thread hole of the connecting pin of being installed in the movable end of little movable plate 11 16, and this horizontal thread hole is used for being connected with the end of thread on this connecting rod 14.Cylinder 15 drives connecting rod 14 and seesaws.Connecting rod 14 drives little movable plate 11 around little pin 10 rotations by connecting pin 16.Clamp the prelocalization pin with this.Offer a little V-shaped groove in the middle of the little fixed head 13, this is the anchor point of prelocalization pin, two frees degree in restriction pcb board all around.Because V-shaped groove mediates, the force rate cylinder that therefore is applied on the prelocalization pin is applied to the power increase of little movable plate 11 movable ends, thereby forms the clamping effect of strengthening.The narrow groove that forms between little fixed head 13 and the little movable plate 11, except that the middle part V-shaped groove can insert the pin, all the other position groove widths can avoid pin to fall in the groove less than the pin diameter, hinder the motion of little movable plate 11.
Back clamp mechanism comprises the fixed head 3, the big movable plate 4 that is used for the clamping and positioning pin that are fixed in the vat of workbench back, be contained in arm-tie 2, rocking arm 7 below the fixed head 3.Be connected with three rocking arms 7 on the arm-tie 2, when cylinder 1 drove arm-tie 2 and seesaws, arm-tie 2 was connected on rocking arm 7 long-armed, and big movable plate 4 is connected on the galianconism of rocking arm 7.Arm-tie 2 drives rocking arm 7 rotations.The pivot point of three rocking arms 7 is fixed on the workbench.Rocking arm 7 rotations drive big movable plate 4 and move.7 rotations of three rocking arms drive big movable plate 4 and move as parallelogram.Because during rocking arm 7 rotations, the arm of force that is connected with arm-tie 2 is greater than the arm of force that is connected with big movable plate 4, the former is preferably two times of the latter, so form force-increasing mechanism.The clamping force of big movable plate 4 is two times of cylinder pulling force.Earlier rocking arm 7 is fixed on the workbench during installation, with pin II9 arm-tie 2 and three rocking arms 7 is coupled together then.With pin I8 big movable plate 4 and three rocking arms 7 are coupled together.
User mode after the installation: the cylinder of this mechanism is a double-acting cylinder, when cylinder 1, when 15 piston rod stretches out, the little movable plate of front air cylinder clamp mechanism is rotated counterclockwise around pin, forms a leg-of-mutton groove C2 between little fixed head and the little movable plate, and the arm-tie of back clamp mechanism travels forward, promoting rocking arm rotates around pin III6; rocking arm drives big movable plate and moves, and makes big movable plate leave fixed head, forms an elongated slot C1.When the piston rod of cylinder 1,15 was withdrawn, the little movable plate of front air cylinder clamp mechanism turned clockwise around pin, and little fixed head and little movable plate clamp; The arm-tie of back clamp mechanism moves backward, and the pulling rocking arm is around pin 6 rotations, and rocking arm drives big movable plate and clamps near realizing to fixed head.During operation, the piston rod of cylinder stretches out, and forms a leg-of-mutton groove C2 between little fixed head and the little movable plate, and big movable plate leaves fixed head, forms an elongated slot C1.To install in advance in the V-shaped groove of prelocalization pin insertion groove C2 of pcb board of alignment pin, among the back alignment pin insertion groove C1.The piston rod of cylinder withdrawal then, little fixed head and little movable plate clamp the prelocalization pin, and fixed head and big movable plate clamp the back alignment pin.Promptly finish accurate location and reliable grip before the pcb board processing.After operation was finished, the piston rod of cylinder stretched out once more, and little fixed head is left in little movable plate rotation, and big movable plate leaves fixed head, only needed this moment pcb board up one is carried, and just finished discharging work.
Above with reference to description of drawings preferred embodiment of the present utility model, those skilled in the art do not break away from essence of the present utility model and spirit, can have multiple flexible program to realize the utility model.The above only is the preferable feasible embodiment of the utility model, is not so limits to interest field of the present utility model, and the equivalence that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
