Description

Technical Field

[0001] This utility model relates to the field of electric welding technology, specifically a positioning mechanism for a large electric welding machine used in the processing of wrought iron products. Background Technology

[0002] Electric welding machines, as a highly efficient welding tool, work by utilizing the instantaneous short circuit between the positive and negative electrodes to generate a high-temperature electric arc. This arc melts the solder on the welding rod and the material to be welded, achieving a strong bond between the objects. Based on the type of output power, electric welding machines are mainly divided into two categories: AC welding machines and DC welding machines. Both cleverly utilize the principle of inductance: the change in inductance at the instant the circuit is switched on and off triggers a violent voltage fluctuation, which in turn generates a high-voltage arc, melting the solder and achieving a tight bond at the atomic level.

[0003] However, the current installation method for large welding machines mostly involves directly fixing them to the ground with bolts. This approach has two major drawbacks: First, the installation position of the welding machine is fixed, and when facing uneven installation surfaces, additional auxiliary parts are often required for adjustment, making the entire installation process complex and time-consuming. Second, when it is necessary to move the welding machine, the operation becomes quite laborious, affecting work efficiency and flexibility. There may already be technical solutions to the above problems in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning mechanism for a large electric welding machine for wrought iron product processing, comprising: a convex processing bracket, a pair of conveyors, a telescopic conveyor, an electric welder, and a positioning structure, wherein the convex processing bracket is mounted on the pair of conveyors, the electric welder is mounted on the convex processing bracket, and the positioning structure is mounted on the convex processing bracket;

[0005] The positioning structure includes: two pairs of clamping loop-shaped horizontal limiting blocks, two pairs of horizontal bidirectional threaded rods, four pairs of horizontal threaded tubes, one pair of horizontal gear sets, one pair of horizontal drive motors, several auxiliary telescopic components, two pairs of vertical angle adjustment components, two pairs of vertical drive motors, two pairs of vertical gear sets, four pairs of vertical threaded rods, four pairs of vertical threaded tubes, two pairs of vertical lifting blocks, and an industrial camera.

[0006] Two pairs of clamping loop-shaped horizontal limiting blocks are mounted on the convex machining bracket via auxiliary telescopic components. Two pairs of horizontal bidirectional threaded rods are respectively inserted into the convex machining bracket via bearings. Four pairs of horizontal threaded tubes are respectively inserted into the two pairs of clamping loop-shaped horizontal limiting blocks, and the four pairs of horizontal threaded tubes are respectively fitted onto the two pairs of horizontal bidirectional threaded rods. One pair of horizontal gear sets are respectively mounted on the two pairs of horizontal bidirectional threaded rods. One pair of horizontal drive motor drive ends are respectively connected to one pair of horizontal gear sets. Two pairs of vertical lifting blocks are mounted on the two pairs of blocks via several auxiliary telescopic components. Inside the clamping loop-shaped horizontal limiting block, four pairs of vertical threaded rods are respectively inserted into the inner side of two pairs of clamping loop-shaped horizontal limiting blocks via bearings; four pairs of vertical threaded tubes are respectively inserted into two pairs of vertical lifting blocks, and four pairs of vertical threaded tubes are respectively movably fitted onto four pairs of vertical threaded rods; two pairs of vertical gear sets are respectively fitted onto four pairs of vertical threaded rods; two pairs of vertical drive motor drive ends are respectively connected to two pairs of vertical gear sets; the industrial camera is mounted on the convex processing bracket; and two pairs of vertical angle adjustment components are respectively mounted on two pairs of vertical lifting blocks.

[0007] It should be noted that, in the above process, the transporter stably and horizontally transports the components to the inside of the vertical angle adjustment assembly. The vertical angle adjustment assembly clamps the components. The vertical drive motor operates, driving the vertical gear set on the drive end of the vertical drive motor. The vertical gear set drives the four pairs of vertical threaded rods on it, which in turn drive the vertical threaded tubes on them. The four pairs of vertical threaded tubes drive the two pairs of vertical lifting blocks on them for stable lifting and lowering. The vertical lifting blocks drive the vertical angle adjustment assembly to vertically lift and lower the components, so that the vertical lifting blocks stably lift and lower inside the two pairs of clamping loop-shaped horizontal limit blocks. The horizontal drive motor operates, driving the horizontal gear set on the drive end of the horizontal drive motor. The horizontal gear set drives the horizontal bidirectional threaded rods on it, which in turn drive the two pairs of clamping loop-shaped horizontal limit blocks to extend and retract relative to each other. At the same time, the auxiliary extension assembly provides active limiting for lifting and lowering.

[0008] Preferably, the vertical angle adjustment assembly includes: an angle ring, an angle drive motor, an angle transmission helical gear, an angle drive helical gear, a concave limiting bracket, a concave telescopic inner block, a pair of horizontal electric push rods, and several telescopic grippers.

[0009] The vertical lifting block has an annular groove. The angle ring is inserted into the inner side of the annular groove via a bearing. The angle drive motor is installed inside the annular groove. The angle transmission helical gear is installed on the angle ring. The angle drive helical gear is installed on the drive end of the angle drive motor, and the angle drive helical gear and the angle transmission helical gear mesh. The concave limiting bracket is inserted into the angle ring. A pair of horizontal electric push rods are installed parallel to each other on the concave limiting bracket. The concave telescopic inner block is movably inserted into the inner side of the concave limiting bracket, and the concave telescopic inner block is installed on the push end of the pair of horizontal electric push rods. Several telescopic grippers are evenly installed on the inner side of the concave telescopic inner block.

[0010] It should be noted that, in the above process, the angle drive motor operates, which drives the angle drive helical gear on the drive end of the angle drive motor to rotate. The angle drive helical gear drives the angle transmission helical gear meshing with it to rotate. The angle transmission helical gear drives the angle ring on it to rotate stably vertically. The angle ring drives the concave limiting bracket on it. The pair of horizontal electric push rods on the inner side of the concave limiting bracket extend and retract, which drives the concave telescopic inner block on it to extend and retract stably horizontally along the inner side of the concave limiting bracket. At the same time, the telescopic claws on the inner side of the concave telescopic inner block squeeze and fix the parts.

[0011] Preferably, the auxiliary telescopic component includes: a horizontal limiting shaft, a vertical limiting shaft, a telescopic slide, and a telescopic slider;

[0012] The horizontal limiting shaft is inserted into the convex machining bracket and is movably inserted into the clamping loop-shaped horizontal limiting block.

The telescopic slide is respectively installed on the convex machining bracket and the clamping loop-shaped horizontal limiting block. The telescopic slider is respectively installed on the clamping loop-shaped horizontal limiting block and the vertical lifting block.

[0013] It should be noted that, as described above, the horizontal limiting axis limits the clamping loop horizontal limiting block horizontally, and the vertical limiting axis limits the vertical lifting block vertically. At the same time, the telescopic slider and the telescopic slide cooperate to stabilize the telescopic effect.

[0014] Preferably, infrared rangefinders are provided on the two pairs of clamping horizontal limiting blocks and the two pairs of vertical lifting blocks.

[0015] Preferably, the two pairs of angle rings are provided with angle scales.

[0016] Preferably, scanning cameras are provided on the two pairs of annular grooves. Beneficial effects

The system has a clear structure and well-defined connections between components, facilitating maintenance and repair. The use of standard parts such as electric push rods and drive motors reduces maintenance costs and difficulty. Attached Figure Description
