Embodiment
The present invention is described in further details below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of prelocalization device by weight-driven, including mounting bracket, gas
Cylinder 2, guiding mechanism, guide rod 4, swing rod and proximity transducer 5.Mounting bracket includes backboard 11 and mounting blocks 12.Backboard 11 and installation
12 integrated casting of block.Backboard 11, which is provided with, to be used to for the prelocalization device of the present embodiment to be installed to the screw before station.
Cylinder 2 is arranged on mounting blocks 12 in a manner of handstand.In the present invention, the mode that cylinder 2 stands upside down refers to the piston rod 21 of cylinder 2
Positioned at the lower section of cylinder 2, and piston rod 21 is vertical.Guiding mechanism includes base 31 and cover plate 32.Base 31 is provided with vertical side
To guide groove 311.Base 31 is fixed on backboard 11 by bolt mode, and cover plate 32 is covered in base 31 by bolt mode
On so that guiding mechanism turns into the strip shape body of the guide groove 311 provided with vertical direction.The strip shape body is located under mounting blocks 12
Side.Guide rod 4 is strip shape body, in guide groove 311, can be slided up and down in guide groove 311.The top of guide rod 4 passes through T-shaped company
Fitting 22 is connected with the piston rod 21 of cylinder 2.It is provided with mounting blocks 12 for the up and down cavity 121 of piston rod 21.Piston rod
21 pass through the connection guide 4 of cavity 121.In the present embodiment, to reduce the friction that guide rod 4 slides in guide groove 311, the He of base 31
Cover plate 32 is made up of copper radical self-lubricating materials.Thus the guiding mechanism of the present embodiment is the copper-based guiding mechanism of non-lubricating.Swing rod
The inverted l-shaped structure being made up of detection bar 61 and pin 62.The swinging axle that the joint portion of detection bar 61 and pin 62 passes through level
63 are arranged on the bottom of guide rod 4.The bottom of guide rod 4 is provided with the swinging chute 64 of vertical direction.The combination of detection bar 61 and pin 62
Portion is located in swinging chute 64.Swing rod can be swung around swinging axle 63.In the effect of no external force, swing rod is at its own
Action of Gravity Field under, around the bottom of swinging axle 63, during the bottom to swing rod center of gravity minimum point, the shape of inverted V-shaped is formed, such as Fig. 3, figure
Shown in 4.Proximity transducer 5 is arranged on the lower end side of guide rod 4 sensor mounting blocks 51 in a manner of handstand, and positioned at pendulum
The top of bar.The handstand of proximity transducer 5 refers to that the detection direction of proximity transducer 5 is located adjacent to the lower section of sensor 5, and shape
Into the test surface of level.When swing rod is acted on by external force, and detection bar 61 swings to peak, proximity transducer 5 is able to detect that
The approach signal of the end of detection bar 61.
The operation principle of the present embodiment is as follows：As shown in figure 3, the prelocalization device of the present embodiment is installed in transport mechanism
Above in the of 91, the processed plate 92 transmitted in transport mechanism 91 transmits along v directions.When initial, gravity of the swing rod at its own
Under effect, the bottom to center of gravity minimum point, the shape of inverted V-shaped is formed.The driving of cylinder 2 causes swing rod to press close to transport mechanism to guide rod 4
91 so that swing rod stops the transmission of plate 92.After plate 92 encounters pin 62 to the transmission of v directions, pin 62 is promoted to v directions,
Detection bar 61 is driven to be swung along w directions, until plate 92 encounters the lower end of guide rod 4, now, detection bar 61 swings to peak,
Proximity transducer 5 is able to detect that the approach signal of the end of detection bar 61.In the present embodiment, pin 62 is designed to work as detection bar
The front end face 621 of 61 pins 62 when swinging to peak overlaps with the side of guide rod 4.Thus, connect when proximity transducer 5 detects
During nearly signal, show that the front position of plate 92 reaches the front end face 621 of pin 62.Followed by, control centre's control cylinder 2 will
Guide rod 4 is lifted up, i.e. u direction in Fig. 3, concedes the gap that plate 92 passes through.
It should be noted that in the present embodiment, the length L of the detection bar 61 and length A of pin 62 meets relation：L=
2.5A.The lever construction being consequently formed, amplify the oscillating stroke of pin 62, improve the accuracy of positioning.In general, to pass through this
The kind lever construction amplification oscillating stroke of pin 62, the length L of the detection bar 61 and length A of pin 62 meet relation：L>2A.This
Outside, it is also necessary to which explanation, detection bar 61 determine that angle of oscillation β's is big with the weight distribution of pin 62 and the position of swinging axle 63
It is small.Angle of oscillation β as shown in figure 3, for the swing rod bottom to center of gravity minimum point when and detection bar 61 on pendulum to angle during peak.Pendulum
Dynamic angle beta is generally 15 ~ 30 degree.In addition, to avoid detection bar 61 from encountering proximity transducer 5 in upper pendulum, swinging axle 63 is generally inclined
The heart designs.Swinging axle 63 is eccentric to represent horizontal centre of the swinging axle 63 not at guide rod 4.It can in addition contain be swung by designing
The maximum height that the overhead height of groove 64 limitation detection bar 61 can be swung, to avoid detection bar 61 from encountering in upper pendulum close to sensing
Device 5.In addition, if detection bar 61 is compared to the length long enough of pin 62, it is possible to causes to be rocked to center of gravity most according to self gravitation
During low spot, angle of oscillation β is excessive, and the height of the end of detection bar 61 is also lower than the height of pin 62.To avoid this situation, such as Fig. 3
It is shown, tray 65 can be set positioned at the lower section of detection bar 61 in swinging chute 64.
Embodiment 2
On the basis of embodiment 1, in order to improve the height of material between prelocalization device and transport mechanism, pin 62 is adopted
Designed with retraction, concrete structure is as follows：Guiding mechanism is provided with vertical slot to make way 33.When cylinder 2 draws high guide rod 4 upwards,
Sensor mounting blocks 51 and detection bar 61 can rise along slot to make way 33, so that pin 62 can be in retraction guide groove 311.
State in the retraction guide groove 311 of pin 62 is as shown in Figure 5.
