Description

Technical Field

[0001] This utility model relates to the field of round steel butt welding technology, specifically a rapid round steel butt welding device. Background Technology

[0002] In modern industrial production, round steel bars are a commonly used material in construction and machinery manufacturing, and often require butt welding to meet the needs of different projects and products. Traditional round steel bar butt welding methods mostly rely on manual operation, using simple tools such as wrenches and clamps for positioning and fixing. This method has many drawbacks.

[0003] Firstly, the precision of manual operation is difficult to guarantee, resulting in significant coaxiality deviations in the butt joints of round steel bars. In high-end manufacturing fields where stringent connection precision requirements exist, this can severely impact product quality and lead to higher defect rates. For example, in the manufacturing of aerospace components, insufficient precision in the butt joints of round steel bars can cause serious safety hazards.

[0004] Secondly, the traditional docking process is extremely cumbersome, requiring workers to adjust the position of the round steel multiple times, which consumes a lot of time and labor costs. Especially in large construction sites or machine processing workshops, where the task of docking batches of round steel is heavy, the inefficient docking method seriously restricts the progress of the project.

[0005] Thirdly, some existing simple butt welding tools lack stability when clamping round steel bars, making them prone to slippage. This not only endangers operator safety but may also damage equipment and the surrounding environment. In complex operating environments, such as high-temperature and high-humidity factory workshops, the performance of traditional butt welding tools is significantly reduced. Therefore, developing a device that can quickly, accurately, and safely butt weld round steel bars has become an urgent problem to be solved in current industrial production. To address these issues, a rapid butt welding device for round steel bars is proposed. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems and provide a quick docking device for round steel bars.

[0007] The specific solution of this utility model is: a quick docking device for round steel, comprising: a housing, wherein clamping mechanisms are symmetrically provided at both ends of the housing, the clamping mechanisms are used to clamp round steel, a connecting slider is provided at the bottom of the clamping mechanism, the connecting slider is slidably connected to the housing, and a driving mechanism is provided inside the housing, the driving mechanism is connected to the clamping mechanisms at both ends through the connecting slider, and is used to drive the clamping mechanisms at both ends to move towards or away from each other;

[0008] The clamping mechanism includes:

[0009] The base is fixedly connected to the outer end of the connecting slider;

[0010] The lower arc-shaped seat is fixedly connected to the base at its bottom;

[0011] The upper arc-shaped seat has one end hinged to the lower arc-shaped seat and the other end threaded to the lower arc-shaped seat. The top of the upper arc-shaped seat is provided with a clamping screw, which passes through the upper arc-shaped seat and is set vertically downward. The bottom of the clamping screw is provided with an arc-shaped pressure block, which is adapted to the outer contour of the round steel to be clamped.

[0012] Furthermore, the drive mechanism includes:

[0013] Two drive racks are rotationally symmetrically arranged at both ends of the housing and are fixedly connected to the connecting sliders at both ends;

[0014] A rotating shaft passes vertically through the middle of the housing from bottom to top and is rotatably connected to the housing. The housing is provided with a drive gear that meshes with the drive racks on both sides. The drive gear is fixedly connected to the middle of the rotating shaft.

[0015] A rotating disk is located at the lower end of a rotating shaft and is fixedly connected to the rotating shaft, and there is a gap between the rotating disk and the ground.

[0016] Furthermore, both the lower arc-shaped seat and the upper arc-shaped seat have a connecting groove at one end of their threaded connection. A connecting screw is hinged in the connecting groove of the lower arc-shaped seat, and a connecting sleeve is threadedly connected to the other end of the connecting screw. The diameter of the connecting sleeve is larger than the width of the connecting groove, and a handle is provided on the top of the connecting sleeve.

[0017] Furthermore, the lower end of the arc-shaped pressure block is provided with a fabric-reinforced rubber layer.

[0018] This utility model has the following beneficial effects:

[0019] 1. Regarding docking accuracy, the device's clamping mechanism is ingeniously designed. Through the hinged and threaded connection of the upper and lower arc-shaped seats, it can tightly conform to the outer contour of the round steel. Furthermore, the arc-shaped pressure block is adapted to the round steel, ensuring stable clamping of the round steel under the action of the clamping screw, effectively reducing positional deviations caused by unstable clamping. Simultaneously, the drive rack and drive gear of the drive mechanism are precisely matched. When the rotating shaft drives the drive gear, it enables the clamping mechanisms at both ends to move synchronously and uniformly towards or away from each other, greatly improving the coaxiality of the round steel docking. This meets the stringent requirements of high-precision docking in high-end manufacturing fields, reducing product defect rates. For example, in the manufacturing of precision mechanical parts, it can significantly improve product quality.

[0020] 2. In terms of work efficiency, this device achieves rapid operation. The rotating disc in the drive mechanism allows operators to easily apply force; rotating the disc drives the clamping mechanism via the rotating shaft, drive gear, and drive rack, quickly adjusting the position of the round steel bars, eliminating the need for repeated manual adjustments as in traditional methods. Furthermore, the graduated markings on the base allow operators to intuitively grasp the position of the clamping mechanism, further improving operational efficiency. In scenarios with batch round steel bar docking tasks, such as large construction sites or machining workshops, it can significantly shorten operation time, accelerate project progress, and reduce labor costs.

[0021] 3. In terms of safety, this device has significant advantages. The connecting slider at the bottom of the clamping mechanism is stably connected to the housing, ensuring that the round steel will not slip during the docking process and protecting the operator's safety. The rubber layer at the lower end of the arc-shaped pressure block not only enhances the friction with the round steel, preventing it from slipping during clamping, but also provides cushioning protection, avoiding damage to the surface of the round steel. In addition, the height-adjustable support feet at the bottom of the housing enable the device to maintain horizontal stability under different ground conditions, reducing the safety risks caused by device shaking and ensuring reliable operation even in complex working environments.
