As shown in fig. 1-3, a two-way material taking large-stroke fork mechanism comprises: fork body 1, fork board 2, slip table 3, actuating mechanism, fixed rack 5, movable rack 6, gear assembly and travel switch 8.

The fork body 1 comprises a bottom plate 11 and left and

right side plates

12, 13.

The fork plate 2 is arranged on the fork body 1 in a sliding way. First sliding blocks 21 are respectively installed on the left side and the right side of the fork plate 2, first sliding rails 14 matched with the first sliding blocks 21 are respectively and fixedly installed at the top ends of the left side plate 12 and the right side plate 13 of the fork body 1, and the fork plate 2 is slidably installed on the fork body 1 through the matching of the first sliding blocks 21 and the first sliding rails 14.

In order to reduce the friction between the first slider 21 and the first slide rail 14 when the fork 2 slides, the present embodiment preferably mounts a plurality of guide wheels 211 on the first slider 21. The guide wheel 211 includes vertical and

horizontal guide wheels

2111 and 2112 rotatably disposed on the first slider 21, the vertical guide wheel 2111 is in contact with the upper bottom surface and/or the lower bottom surface of the first rail 14, respectively, and the horizontal guide wheel 2112 is in contact with the side surface of the first rail 14. The transverse and

vertical guide wheels

2111 and 2112 can convert sliding friction between the first slider 21 and the first guide rail 14 into rolling friction, thereby reducing friction between the first slider 21 and the first slide rail 14 when the fork 2 slides.

The sliding table 3 is arranged in the fork body 1 in a sliding manner. A second sliding block 31 is fixedly mounted on the sliding table 3, a second guide rail 15 matched with the second sliding block 31 is fixedly mounted in the middle of the right side plate 13 of the fork body 1, and the sliding table 3 is mounted on the fork body 1 through the second sliding block 31 and the second guide rail 15 in a matched mode.

The driving mechanism is arranged on the fork body 1 and used for driving the sliding table 3 to slide. The drive mechanism includes a drive link shaft 41 and a driven link shaft 42 rotatably provided on the fork body 1. The drive link shaft 41 is driven to rotate by a conventional drive device, and the drive link shaft 41 of the present embodiment is preferably driven using a motor. Two ends of the driving chain shaft 41 are rotatably arranged at the front ends of the left and

right side plates

12 and 13 of the fork body 1 through bearing seats and bearings respectively, and two ends of the driven chain shaft 42 are rotatably arranged at the tail ends of the left and

right side plates

12 and 13 of the fork body 1 through bearing seats and bearings respectively. A drive sprocket 43 and a driven sprocket 44 are fixedly mounted on the drive chain shaft 41 and the driven chain shaft 42, respectively. A chain 45 fixedly connected with the sliding table 3 is engaged and installed on the driving sprocket 43 and the driven sprocket 44. In operation, the driving chain shaft 41 is driven by the driving motor to rotate, so that the driven chain shaft 42, the driving chain wheel 43 and the driven chain wheel 44 drive the chain 45 to move, and the chain 45 drags the sliding table 3 to slide in the fork body 1.

The fixed rack 5 is fixedly arranged on the bottom plate 11 of the fork body 1 through a fastener such as a bolt.

The movable rack 6 is fixedly arranged on the bottom surface of the fork plate 2 through fasteners such as bolts and the like.

When the sliding table 3 slides on the fork body 1, the gear assembly can slide along with the sliding table 3, and since the first gear 71 is meshed with the fixed rack 5, when the gear assembly slides along with the sliding table 3, the first gear 71 can rotate along the fixed rack 5 and drive the second gear 72 to rotate through the gear shaft 73. Meanwhile, as the moving rack 6 is meshed with the second gear 72, the moving rack 6 and the fork plate 2 can extend and retract under the driving of the gear assembly, and the extending and retracting stroke of the moving rack 6 and the fork plate 2 is equal to the sliding displacement of the gear assembly plus the arc length of the second gear 72.

In order to further increase the telescopic stroke of the fork 2, the present embodiment preferably makes the diameter of the second gear 72 larger than the diameter of the first gear 71. Since the angular velocities of the first and

second gears

71 and 72 during rotation are the same, the linear velocity of the rotation of the second gear 72 is increased by increasing the diameter of the second gear 72, thereby increasing the arc length over which the second gear 72 rotates and further increasing the telescopic stroke of the yoke 2.

The travel switch 8 is fixedly arranged on the fork body 1, and the travel switch 8 is used for controlling the telescopic distance of the fork plate 1.
