Description
Technical Field
[0001] This application relates to the field of hot-dip galvanizing equipment technology, and in particular to a precision positioning hot-dip galvanizing indexing machine. Background Technology
[0002] The precision positioning hot-dip galvanizing indexing machine is a key piece of equipment used in hot-dip galvanizing production lines. It is primarily used for the precise positional conversion and orientation adjustment of galvanized workpieces (such as steel, pipes, and plates). Its core function is to precisely move the workpiece along a preset trajectory to a designated station between each step of the hot-dip galvanizing process (such as degreasing, pickling, galvanizing, and cooling), ensuring the continuity of the galvanizing process and the uniformity of the coating, while avoiding quality defects caused by workpiece collisions or positional deviations. This equipment is widely used in steel manufacturing, metal processing, and other industrial fields requiring hot-dip galvanizing treatment.
[0003] In practical use, it has been found that traditional hot-dip galvanizing indexing equipment mostly relies on manual or simple mechanical assistance. Manual handling is not only inefficient, but also poses safety hazards in high-temperature environments. Although some automated equipment uses robotic arms or conveyor belts for indexing, the lack of a precise positioning mechanism makes the plates prone to displacement and collision during transport, which not only damages the surface of the plates, but may also cause equipment failure and increase maintenance costs. Therefore, we propose a precise positioning hot-dip galvanizing indexing machine to solve the above problems. Utility Model Content
[0004] The purpose of this application is to address the shortcomings of existing technologies, such as low efficiency and safety hazards in high-temperature environments when manually handling sheet metal during transposition, and the inability to accurately position the sheet metal. Therefore, this application proposes a precise positioning hot-dip galvanizing transposition machine.
[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a precision positioning hot-dip galvanizing indexing machine, comprising an operating table, a galvanizing tank fixedly installed on the right side of the operating table, a back plate fixedly installed on the rear side of the operating table and the rear side of the galvanizing tank, an indexing box fixedly installed on the top front side of the back plate, an indexing mechanism provided inside the indexing box, a first seat hole opened at the bottom of the indexing box; a lead screw seat slidably installed in the first seat hole, a through hole opened on the lead screw seat, a lifting mechanism provided between the through hole and the lead screw seat, a positioning box provided above the operating table, a second motor fixedly installed on the left side of the positioning box, a bidirectional mechanism provided between the second motor and the positioning box, a second seat hole opened at the bottom of the positioning box, a positioning mechanism provided below the positioning box, a liquid guiding mechanism provided between the operating table and the galvanizing tank, a controller provided on the front side of the operating table, and the controller electrically connected to the second motor.
[0006] A further configuration of this application is as follows: the indexing mechanism includes a first motor and a lead screw. The first motor is fixedly installed on the inner wall of the left side of the indexing box, and the lead screw is fixedly installed on the output shaft of the first motor. The right end of the lead screw is rotatably connected to the inner wall of the right side of the indexing box. The lead screw seat is threaded onto the lead screw. The first motor is electrically connected to the controller.
[0007] By adopting the above technical solution and by setting up a rotation mechanism, the first motor can drive the lead screw seat to move left and right, thereby enabling the plate to move left and right through the lifting screw, threaded cylinder, positioning box and positioning plate, and achieving the purpose of rotation of the plate.
[0008] A further configuration of this application is as follows: the lifting mechanism includes a lifting screw and a threaded cylinder. The lifting screw is rotatably installed on the inner wall of the top of the through hole. The bottom end of the lifting screw extends to below the screw seat. The threaded cylinder is threadedly sleeved on the bottom end of the lifting screw. A limit mechanism is provided between the threaded cylinder and the screw seat. A gear mechanism is provided between the lifting screw and the indexing box. The bottom of the threaded cylinder is fixedly connected to the top of the positioning box.
[0009] By adopting the above technical solution and by setting up a lifting mechanism, the lifting screw can drive the threaded cylinder to move up and down, thereby achieving the purpose of lifting the plate through the positioning box, positioning plate and scraper plate.

[0011] By adopting the above technical solution and setting a limit mechanism, the threaded cylinder can be constrained by the fixed plate and the sliding rod, so that the threaded cylinder can only move up and down in the vertical direction.
[0012] A further configuration of this application is as follows: the gear mechanism includes a fixed plate, a rack plate and a gear. The same fixed plate is fixedly installed on the inner walls of both sides of the indexing box. The fixed plate is located below the first motor. A rack plate is fixedly installed on the front side of the fixed plate. A gear is fixedly sleeved on the lifting screw. The gear is located in the through hole. The rack plate and the gear are adapted to each other.

The positioning plates are fixedly installed at the bottom of the screw seat, and the shovel plates are fixedly installed at the bottom of the adjacent sides of the two positioning plates. The positioning pads are located above the shovel plates.
[0017] By adopting the above technical solution and setting a positioning mechanism, the shovel plate can gently lift both ends of the plate while continuously providing stable support. This enables the positioning pad to fit tightly against both sides of the plate and evenly squeeze to firmly clamp and fix the plate, preventing displacement or shaking during subsequent transportation.

[0033] Specifically, the lifting mechanism includes a lifting screw 601 and a threaded cylinder 602. The lifting screw 601 is rotatably installed on the inner wall of the top of the through hole 6. The bottom end of the lifting screw 601 extends to the bottom of the screw seat 303. The threaded cylinder 602 is threadedly fitted at the bottom end of the lifting screw 601. A limit mechanism is provided between the threaded cylinder 602 and the screw seat 303. A gear mechanism is provided between the lifting screw 601 and the indexing box 3. The bottom of the threaded cylinder 602 is fixedly connected to the top of the positioning box 5.
[0034] Specifically, the limiting mechanism includes a limiting plate 603 and a sliding rod 604. The limiting plate 603 is fixedly sleeved on the outside of the threaded cylinder 602, and the sliding rod 604 is fixedly installed at the bottom of the screw seat 303. The limiting plate 603 is slidably sleeved on the sliding rod 604.
[0035] Specifically, the gear mechanism includes a fixed plate 7, a rack plate 701, and a gear 702. The same fixed plate 7 is fixedly installed on the inner walls of both sides of the indexing box 3. The fixed plate 7 is located below the first motor 301. The rack plate 701 is fixedly installed on the front side of the fixed plate 7. The gear 702 is fixedly sleeved on the lifting screw 601. The gear 702 is located in the through hole 6. The rack plate 701 and the gear 702 are adapted to each other.
[0036] Specifically, the bidirectional mechanism includes a bidirectional screw 502 and two screw seats 503. The bidirectional screw 502 is fixedly installed on the output shaft of the second motor 501. The right end of the bidirectional screw 502 is rotatably connected to the inner wall of the right side of the positioning box 5. Two screw seats 503 are threaded on the bidirectional screw 502. The screw seats 503 are slidably connected to the second seat hole 504.
[0037] Specifically, the positioning mechanism includes two positioning plates 8, two scraper plates 801 and two positioning pads 802. The positioning plates 8 are fixedly installed at the bottom of the screw seat 503. The scraper plates 801 are fixedly installed at the bottom of the adjacent side of the two positioning plates 8. The positioning pads 802 are provided on the adjacent side of the two positioning plates 8. The positioning pads 802 are located above the scraper plates 801.
[0038] Specifically, the liquid guiding mechanism includes a liquid guiding groove 101 and a liquid guiding hole 201. The liquid guiding groove 101 is provided on the right side of the top of the operating table 1, and the liquid guiding hole 201 is provided on the left side of the galvanizing tank 2. The liquid guiding groove 101 and the liquid guiding hole 201 are compatible.
[0039] In this application, during operation, the sheet material to be galvanized is first placed on the operating table 1, and then the second motor 501 is started, which drives the bidirectional screw 502 to rotate, causing the two screw seats 503 to move relative to each other along the bidirectional screw 502. The screw seats 503 can drive the positioning plate 8 to approach the sheet material. The bottom scraper plate 801, with its inclined blade design, can gently scrape up both ends of the sheet material with a smooth pushing motion, while continuously providing stable support to prevent the sheet material from tipping over or deforming due to the shift of the center of gravity, thus laying the foundation for accurate positioning. As the positioning plate 8 moves further, the positioning pad 802 can be made to fit tightly against both sides of the sheet material, and the uniform compression can firmly clamp and fix the sheet material to prevent displacement or shaking during subsequent transportation.
[0040] After positioning is completed, the first motor 301 is started, and the lead screw 302 rotates accordingly. The lead screw seat 303 moves to the right along the first seat hole 304 under the threaded transmission. When the lead screw seat 303 moves to the position of the rack plate 701, the gear 702 in the through hole 6 gradually meshes with the rack plate 701 on the fixed plate 7. Since the rack plate 701 is fixed, the gear 702 is driven to rotate and drives the lifting screw 601 to rotate. The spiral transmission structure formed by the lifting screw 601 and the threaded cylinder 602 is constrained by the limiting plate 603 and the sliding rod 604, so that the threaded cylinder 602 can drive the positioning box 5, the positioning plate 8, the positioning pad 802 and the plate as a whole to move down. This can achieve the purpose of gradually and smoothly moving the plate down into the zinc plating liquid in the zinc plating tank 2 for zinc plating operation, thereby achieving the purpose of stable rotation of the plate and improving work efficiency.
[0041] After galvanizing, the first motor 301 rotates in reverse, driving the lead screw 302 to reverse, causing the lead screw seat 303 to move to the left along the first seat hole 304. The gear 702 moves in reverse with the lead screw seat 303 and meshes with the rack plate 701, driving the lifting screw 601 to reverse. The threaded cylinder 602 moves upward under the action of the limiting mechanism, lifting the positioning box 5, the positioning mechanism, and the galvanized plate above the galvanizing tank 2. When the plate moves above the liquid guiding tank 101, the controller 9 controls the first motor 301 to rotate in reverse. When motor 301 stops, the residual galvanizing liquid on the surface of the sheet drips into the liquid guide tank 101 under gravity, and then flows back into the galvanizing tank 2 through the liquid guide hole 201, which can realize the recycling of galvanizing liquid and reduce waste and pollution. When the galvanizing liquid stops dripping, the controller 9 restarts the first motor 301 to rotate in the opposite direction and moves the sheet to the initial position. Finally, the second motor 501 rotates in the opposite direction, driving the positioning plate 8 and the scraper plate 801 to release the sheet, completing the entire hot-dip galvanizing transfer process.
