Embodiment 1
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of prelocalization device relying on weight-driven, comprises installing rack, cylinder 2, guiding mechanism, guide rod 4, fork and proximity transducer 5.Installing rack comprises backboard 11 and mounting blocks 12.Backboard 11 and the integrated casting of mounting blocks 12.Backboard 11 is provided with for the prelocalization device of the present embodiment is installed to the screw before station.Cylinder 2 is arranged on mounting blocks 12 in the mode of standing upside down.In the present invention, the mode that cylinder 2 stands upside down refers to that the piston rod 21 of cylinder 2 is positioned at the below of cylinder 2, and piston rod 21 is vertical.Guiding mechanism comprises base 31 and cover plate 32.Base 31 is provided with the gathering sill 311 of vertical direction.Base 31 is fixed on backboard 11 by bolt mode, and cover plate 32 is covered on base 31 by bolt mode, guiding mechanism is become be provided with the strip shape body of the gathering sill 311 of vertical direction.This strip shape body is positioned at the below of mounting blocks 12.Guide rod 4 is strip shape body, is located in gathering sill 311, can slide up and down in gathering sill 311.Guide rod 4 top is connected with the piston rod 21 of cylinder 2 by T-shaped connector 22.Be provided with in mounting blocks 12 for the up and down cavity 121 of piston rod 21.Piston rod 21 connects guide rod 4 through cavity 121.In the present embodiment, for reducing the friction that guide rod 4 slides in gathering sill 311, base 31 and cover plate 32 are made up of copper radical self-lubricating materials.The guiding mechanism of the present embodiment is non-lubricating copper base guiding mechanism thus.The inverted L-shaped structure that fork is made up of test rod 61 and pin 62.The joint portion of test rod 61 and pin 62 is arranged on the bottom of guide rod 4 by the swinging axle 63 of level.The bottom of guide rod 4 is provided with the swinging chute 64 of vertical direction.The binding site of test rod 61 and pin 62 is in swinging chute 64.Fork can swing around swinging axle 63.When the effect not having external force, fork, under the Action of Gravity Field of himself, around swinging axle 63 bottom, when the bottom is to fork center of gravity minimum point, forms the shape of inverted V-shaped, as shown in Figure 3, Figure 4.Proximity transducer 5 is arranged on the lower end side of guide rod 4 in the mode of standing upside down by sensor mounting blocks 51, and be positioned at the top of fork.The handstand of proximity transducer 5 refers to that the detection direction of proximity transducer 5 is positioned at the below of proximity transducer 5, and forms the test surface of level.When fork is by External Force Acting, when test rod 61 swings to peak, proximity transducer 5 can detect the approach signal of test rod 61 end.
The operation principle of the present embodiment is as follows: as shown in Figure 3, and the prelocalization device of the present embodiment is installed in above connecting gear 91, and the processed plate 92 that connecting gear 91 transmits transmits along v direction.Time initial, fork is under the Action of Gravity Field of himself, and the bottom, to center of gravity minimum point, forms the shape of inverted V-shaped.Cylinder 2 is driven into guide rod 4 and makes fork press close to connecting gear 91, makes fork stop the transmission of plate 92.Plate 92 promotes pin 62 to v direction after encountering pin 62 to the transmission of v direction, drives test rod 61 to swing along w direction, until the lower end of guide rod 4 encountered by plate 92, now, test rod 61 swings to peak, and proximity transducer 5 can detect the approach signal of test rod 61 end.In the present embodiment, the front end face 621 that pin 62 is designed to the pin 62 when test rod 61 swings to peak overlaps with the side of guide rod 4.Thus, when proximity transducer 5 detects approach signal, show that the front position of plate 92 arrives the front end face 621 of pin 62.In addition after, guide rod 4 upwards promotes by control centre's control cylinder 2, i.e. u direction in Fig. 3, abdicates the gap that plate 92 passes through.
It should be noted that, in the present embodiment, the length L of the test rod 61 and length A of pin 62 meets relation: L=2.5A.The lever construction formed thus, amplifies pin 62 oscillating stroke, improves the accuracy of location.In general, for amplifying pin 62 oscillating stroke by this lever construction, the length L of the test rod 61 and length A of pin 62 meets relation: L>2A.In addition, also it should be noted that, test rod 61 determines the size of angle of oscillation β with the distribution of weight of pin 62 and the position of swinging axle 63.Angle of oscillation β as shown in Figure 3, for the fork bottom is put to angle during peak to during center of gravity minimum point and on test rod 61.Angle of oscillation β is generally 15 ~ 30 degree.In addition, for avoiding test rod 61 to encounter proximity transducer 5 when upper pendulum, swinging axle 63 is eccentric design usually.Swinging axle 63 bias represents that swinging axle 63 is not positioned at the horizontal centre of guide rod 4.The maximum height that can also be swung by design swinging chute 64 overhead height restriction test rod 61 in addition, encounters proximity transducer 5 to avoid test rod 61 when upper pendulum.In addition, if test rod 61 is compared to pin 62 length long enough, when likely causing being rocked to center of gravity minimum point according to self gravitation, angle of oscillation β is excessive, and the height of the aspect ratio pin 62 of test rod 61 end is also low.For avoiding this situation, as shown in Figure 3, can in swinging chute 64, the below being positioned at test rod 61 arranges tray 65.
Embodiment 2
On the basis of embodiment 1, in order to improve the height of material between prelocalization device and connecting gear, pin 62 adopts retraction to design, and concrete structure is as follows: guiding mechanism is provided with vertical slot to make way 33.When cylinder 2 upwards draws high guide rod 4, sensor mounting blocks 51 and test rod 61 can rise along slot to make way 33, thus make pin 62 can in retraction gathering sill 311.State in pin 62 retraction gathering sill 311 as shown in Figure 5.
