Description

Technical Field

[0001] This utility model relates to the field of metal welding technology, and in particular to a welding fixture for metal medium plates. Background Technology

[0002] Medium-thick metal plates, such as those made of steel or aluminum, are widely used in construction, manufacturing, and engineering. These plates typically have high strength and good corrosion resistance, making them suitable for the fabrication of structural and mechanical components.

[0003] The existing metal plate welding fixture includes a base, clamping mechanism, contour cover plate, locating pins, and cylinder. The base, made of aluminum alloy, serves as the foundation supporting the entire fixture, ensuring stability and accuracy during welding. The clamping mechanism uses a cylinder-pressurized jaws to clamp the cover plate, securing the workpiece and preventing movement during processing. The cylinder provides power to the clamping structure, outputting approximately 0-3 MPa pressure. The contour cover plate is the core functional unit in the welding fixture, enabling high-precision assembly and controlling the accuracy of the basic positioning and welding points. During production, the worker precisely places the product into the base according to the locating pins, then accurately places the cover plate. After pressing the start button, the clamping structure rotates and fixes the cover plate under the action of the cylinder, clamping the product. Alternatively, the worker places the product into the base according to the locating pins, then places the cover plate on top of the product according to the locating pins. After pressing the start button, the cylinder rotates the jaws onto the cover plate, fixing it and ensuring product stability during processing. Because the aforementioned clamping mechanism requires manual tightening of the cover plate to secure the workpiece, and only one piece can be processed at a time, it results in excessively long manual operation time, low machine uptime, and the risk of misalignment during manual tightening, leading to poor welding during product processing. Furthermore, the close proximity of the processing platform to the worker's operating area poses a production safety risk.

[0004] Therefore, a new solution is needed. Utility Model Content

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0016] Figure 1 The diagram shown is a structural schematic of a welding fixture provided in an embodiment of this utility model. Figure 1As shown, the welding fixture includes a mounting base plate 10 and multiple welding modules mounted on the mounting base plate 10. Each welding module provides a welding station, thereby improving welding efficiency. Specifically, each welding module includes a sliding component 210, a fixed base 220, a contoured cover plate 230, a guide component 240, and a support frame 250. The sliding component 210 and the guide component 240 are mounted on the upper surface of the mounting base plate 10, and the fixed base 220 is mounted on the upper surface of the sliding component 210. The sliding component 210 drives the fixed base 220 to move on the upper surface of the mounting base plate 10, and the sliding component allows the fixed base to move freely on the upper surface of the mounting base plate, thereby realizing multi-station production. The contoured cover plate 230 is mounted on the upper end of the guide assembly 240, and the guide assembly 240 drives the contoured cover plate 230 to move up and down in a direction perpendicular to the upper surface of the mounting base plate 10. The guide assembly not only allows the contoured cover plate to move vertically, but also ensures accurate alignment of the cover plate, which effectively solves the problem of positioning groove accuracy, thereby avoiding quality problems caused by human error. The automated operation of the contoured cover plate driven by the guide assembly reduces reliance on manual intervention, saving labor costs and reducing the possibility of operational errors, further improving work efficiency. The support frame 250 is mounted on one end of the mounting base plate 10, and a welding receiving portion is formed between the lower surface of the support frame 250 and the upper surface of the mounting base plate 10. One end of the guide assembly 240 and the sliding assembly 210 is located in the welding receiving portion. The welding receiving portion is located approximately 30 cm away from the manual operation surface, avoiding the risk of injury to operators due to close proximity during welding. The design of the welding receiving portion and the sliding assembly allows operators to safely perform welding work.

[0017] Figure 2 The image shown is a partial exploded view of a welding fixture provided in an embodiment of this utility model. Figure 2 As shown, the support frame 250 includes a first vertical support plate 2501, a second vertical support plate, and a horizontal support plate 2502. The lower ends of the first vertical support plate 2501 and the second vertical support plate are fixed to the mounting base plate 10. The horizontal support plate 2502 is installed on the upper ends of the first vertical support plate 2501 and the second vertical support plate. The first vertical support plate 2501 and the second vertical support plate are respectively provided with grooves.

[0018] Specifically, in this embodiment, the guide assembly is responsible for precisely controlling the Z-axis movement of the contour cover plate via a pneumatic system, ensuring accurate positioning of the product during processing and avoiding any unnecessary shaking, thereby improving processing precision. Figure 2As shown, the guide assembly 240 includes a first control cylinder 2401, a first sensor, a second control cylinder, a second sensor, a first lead screw cylinder 2402, a second lead screw cylinder 2403, a third lead screw cylinder 2404, and a fourth lead screw cylinder 2405. The first lead screw cylinder 2402, the second lead screw cylinder 2403, the third lead screw cylinder 2404, and the fourth lead screw cylinder 2405 are installed between the horizontal support plate 2502 and the mounting base plate 10 and pass through the contouring section. At the four ends of the cover plate 230, the first control cylinder 2401 and the second control cylinder are respectively located in the grooves of the first vertical support plate 2501 and the second vertical support plate. The first control cylinder 2401 is electrically connected to the first sensor and mechanically connected to the first lead screw cylinder 2402 and the second lead screw cylinder 2403. The second control cylinder is electrically connected to the second sensor and mechanically connected to the third lead screw cylinder 2404 and the fourth lead screw cylinder 2405. The first control cylinder 2401 is responsible for controlling the up and down movement of the contoured cover plate through air pressure; the second control cylinder cooperates with the first control cylinder to coordinate and control the precise movement of the contoured cover plate. The lead screw cylinder passes through the horizontal support plate 2502 and the mounting base plate 10, providing necessary support for the contoured cover plate and ensuring its precise sliding. The sensor is used to detect the position of the contoured cover plate. When the product reaches the designated position, the sensor sends a signal to the cylinder, thereby precisely controlling the positioning of the contoured cover plate.

[0019] In this embodiment, the main function of the lead screw cylindrical component is to ensure the precise up-and-down movement of the contoured cover plate. The lead screw is designed with high transmission precision, preventing deviations during the sliding of the contoured cover plate and ensuring it moves precisely up and down along a predetermined trajectory. Four lead screw cylindrical components are installed between the horizontal support plate and the mounting base plate, passing through the four ports of the contoured cover plate, providing stable support and ensuring the cover plate does not shift or jam during sliding. The cylinder, as the power source for the guide assembly, is responsible for driving the rotation of the lead screw cylindrical components, thereby realizing the up-and-down sliding of the contoured cover plate. The air pressure adjustment of the cylinder can precisely control the moving speed and position of the cover plate, and its cooperation with the sensor ensures that the cover plate can move precisely according to the actual needs of the product. The main function of the sensor is to monitor the position of the contoured cover plate in real time. When the product moves to the designated position, the sensor sends a signal to the control cylinder, instructing the cylinder to stop working and maintain the accurate positioning of the cover plate. Through sensor feedback, the cylinder system can precisely control the up and down movement of the cover plate, thereby ensuring that the cover plate presses firmly against the product and prevents the product from shaking during processing. It can ensure that the conforming cover plate always stays in the ideal position throughout the entire working process, avoiding product quality problems caused by positional errors.

[0020] The guide assembly, through a precise control system, ensures the accurate positioning and movement of the contour cover plate, avoiding positioning deviations caused by operational errors or mechanical wear, thereby improving machining accuracy. Through a precisely designed lead screw cylinder, cylinder power system, and sensor feedback mechanism, the guide assembly provides high-precision and high-stability control during machining, significantly improving the overall efficiency and quality of welding or machining.

[0021] Figure 3 As shown Figure 1 The diagram shows the structure of the sliding component. Figure 3 As shown, the sliding assembly 210 includes a first guide rail 2101, a second guide rail 2102, and a slide table 2103. The lower surfaces of the first guide rail 2101 and the second guide rail 2102 are fixed to the mounting base plate 10. The slide table 2103 is slidably mounted on the upper surfaces of the first guide rail 2101 and the second guide rail 2102. The lower surfaces of the first guide rail 2101 and the second guide rail 2102 are respectively fixed to the mounting base plate 10. These guide rails provide a stable and precise support platform, ensuring that the slide table can move smoothly along a predetermined trajectory. The main function of the guide rails is to guide the movement of the slide table, ensuring that the slide table moves precisely along a specific path. As part of the sliding assembly, the slide table 2103 serves to support the fixed base 220. It is mounted on the upper surfaces of the first and second guide rails, and the smooth movement of the base is achieved through sliding. The slide table ensures that the welding fixture maintains accuracy and stability during efficient operation. With precise guide rails and sliding tables, welded workpieces can be smoothly transferred between multiple stations, avoiding errors caused by manual adjustments and ensuring that the welding process at each station is completed efficiently and accurately. The sliding component design enables multi-station production of products.

[0022] Specifically, in this embodiment, the fixed base 220 has a product receiving groove 2201 at its center, and multiple positioning pins 2202 are arranged around the upper surface of the fixed base 220. The product receiving groove at the center of the fixed base 220 is designed to ensure stable placement of the product. This design reduces product movement or shaking during processing, ensuring processing accuracy and stability. The multiple positioning pins around the upper surface of the fixed base allow employees to accurately place the product on the base, avoiding the inaccuracies of manual placement. The positioning pins provide fixing points, ensuring the accuracy of product placement each time and avoiding processing errors caused by product offset.

[0023] In use, employees simply place the product according to the position of the positioning pins and press the start button; the system will then automatically complete the subsequent work. This reduces manual intervention and improves operational efficiency and accuracy. The slide table, carrying the base, moves along the guide rail to the designated position. This design allows the base to move smoothly, ensuring the product is always in a precise position during each processing step. The efficient trajectory control of the slide table further ensures the stability and accuracy of the base's movement, avoiding processing deviations caused by base position errors. Once the slide table reaches the designated position, the sensor sends a feedback signal to the control system, and the cylinder begins to work. The cylinder pushes the lead screw cylinder, causing the cover plate to move downwards along the set path, precisely pressing the product. During this process, the precise control of the cylinder and the stability of the lead screw cylinder ensure smooth and uniform movement of the cover plate, avoiding product deformation caused by uneven pressing of the cover plate. Once the cover plate has pressed the product firmly, the cylinder stops working, indicating that the product has entered a stable positioning state, providing a stable foundation for the welding process. The automatic control and stop function of the cylinder greatly improves the automation level of the operation and reduces human error. Compared to traditional manual or inefficient mechanical operations, the improved system, through automatic control, positioning pins, slide rails, and cylinder control, makes the entire process more efficient and precise. Employees only need to perform initial operations (such as placing the product and pressing the start button), while the rest is handled automatically by the system, significantly improving production efficiency. Through these improvements, the system can complete product positioning, clamping, and welding in a shorter time, resulting in a smoother workflow and significant savings in labor and time costs. According to actual data, the improved fixture is approximately 30% more efficient than the previous fixture, meaning more products can be processed in the same amount of time, thus greatly increasing production capacity and output.
