Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal wire production, specifically to an automatic transfer truss with I-beam wheels. Background Technology
[0002] In metal wire production, during the transition between different processes, the wire needs to be wound onto I-beams for processing in the next step, such as quantitative winding or further processing. The I-beam rotating gantry automatically rotates and positions full or empty I-beams during the process. Previously, the first two generations of automatic I-beam rotating gantry systems encountered the following problems in practical application: First, asynchronous movement on both sides. Although both wheels were controlled by servo motors, deviations occurred during operation, requiring frequent correction. Second, the lifting mechanism of the first two generations used a screw-nut drive; after prolonged shutdown and restart, the screw would bend, causing the screw nut to seize, resulting in high maintenance costs. Utility Model Content

The X-axis moving platform includes an X-axis moving mechanism body, a limiting roller, and a traveling roller. The X-axis moving mechanism body includes X-axis crossbeams on both sides and Y-axis crossbeams on both sides. A Y-axis track is arranged above the Y-axis crossbeams on both sides. An X-axis traveling roller and an X-axis limiting roller are arranged at the lower end of the X-axis moving mechanism body. The X-axis traveling roller and the X-axis limiting roller mesh with the rack.
[0008] The X-axis moving power mechanism is arranged on one end beam of the X-axis moving platform. The X-axis moving power mechanism includes an X-axis servo motor, an X-axis gearbox, an X-axis universal coupling, an X-axis commutator, and an X-axis traveling gear. The X-axis gearbox is installed on the center of the side of the beam of the X-axis moving platform. The X-axis servo motor is installed at the input end of the X-axis gearbox. The output end of the X-axis gearbox is connected to the input end of the X-axis commutator through the X-axis universal coupling. The X-axis traveling gear is installed at the output end of the X-axis commutator and meshes with a rack. The X-axis moving power mechanism drives the X-axis moving platform to move in the X-axis direction through the gear and rack drive.
[0009] The Z-axis lifting mechanism includes a sliding sleeve and a bracket; the sliding sleeve and bracket are respectively fixed on the Y-axis moving platform; the Z-axis servo motor and the Z-axis reducer are both fixed on the bracket; the sprocket is mounted on the motor shaft of the Z-axis servo motor, and the large sprocket and brake wheel are mounted on the input shaft of the Z-axis reducer, with the sprocket and large sprocket connected by a toothed chain; the lifting reel is mounted on the output end of the Z-axis reducer, one end of the lifting chain is mounted on the lifting reel, and the other end is mounted on the lifting guide post; the lifting guide post is installed in the sliding sleeve, and can slide freely up and down in the sliding sleeve, allowing the Z-axis lifting mechanism to move up and down; the brake is mounted on the bracket, and when work stops, the brake clamps the brake wheel, stopping the up and down components of the Z-axis lifting mechanism.
[0010] The grabbing and rotating mechanism is fixed at the lower end of the Z-axis lifting mechanism and includes a grabbing arm, a rotating shaft, a cylinder, a drive gear, a rotating support gear and a rotating frame, a rotating reducer and a rotating motor.

The lower part of the grabbing arm clamps an I-beam wheel. The rotating motor is arranged on the lifting guide column and is directly connected to the drive gear via the rotating reducer. The drive gear meshes with the gears of the rotating support gear and rotating frame.
[0011] The present invention, employing the above technical solution, has the following beneficial effects: In this invention, the intermediate transmission medium for the lifting mechanism's ascent and descent is a chain, which is a flexible connection, unlike the previous screw and nut transmission. This eliminates the possibility of jamming, ensuring smooth up-and-down sliding, reducing mechanical failures, lowering maintenance costs, and improving operating efficiency. Furthermore, the X-axis and Y-axis travel utilize a one-to-two universal coupling to provide power to the gears on both sides, constituting a rigid connection transmission. Both gears rotate synchronously, ensuring synchronized travel distance and speed on both sides. This results in higher positioning accuracy for the entire truss compared to systems driven by two servos. Attached Figure Description

[0025] In this invention, the intermediate transmission medium for the lifting mechanism's ascent and descent is a chain, a flexible connection unlike the previous screw and nut transmission. This eliminates the possibility of jamming, ensuring smooth up-and-down sliding, reducing mechanical failures, lowering maintenance costs, and improving operational efficiency. Furthermore, the X-axis and Y-axis travel utilize a split-type universal coupling to provide power to the gears on both sides, a rigid connection transmission. Both gears rotate synchronously, ensuring synchronized travel distance and speed on both sides. This results in higher positioning accuracy for the entire truss compared to systems driven by two servos.
