Description

Technical Field

[0001] The utility model belongs to the technical field of welding devices and specifically discloses a welding positioning device for a main frame of a cutting machine. Background Art

[0002] At present, the method commonly used by domestic cutting machine manufacturers when assembling the main structure is to rely on the practical experience of individual welding workers and simple welding fixtures designed by themselves. The main problem with this method is that the welding tolerance is significant, and it is difficult to achieve precise control of the welding size. The high dependence on worker skills may cause the welding operation to fail to proceed smoothly once the welding operator is replaced. The welding results of each batch of products are inconsistent, and some products have significant deviations in welding dimensions, which leads to the tilt of the main structure after the finished product is assembled. In addition, the disassembly and reassembly process of the main structure before and after the welding process is cumbersome, which is not conducive to improving welding efficiency and is difficult to adapt to the requirements of enterprises to quickly respond to order needs and execute production plans.

[0003] The adjustable engine frame welding tool with patent application number CN102328171B includes a fixed plate, a limit block, a limit slider, a positioning slider and a cushion block. The limit block and the limit slider are used to limit the horizontal degree of freedom of the frame bend; the positioning slider is used to position the left beam, right beam or rear beam to be welded to the frame bend; the cushion block is used to position the bottom plate to be welded to the frame bend, and the limit slider and the positioning slider are connected to the fixed plate through a support plate. The above device fixes the device through a fixed plate, and it is impossible to achieve multi-angle fixation of the device, and the device fixing effect is poor. Therefore, it is urgent for technical personnel in this field to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is the problem of inaccurate positioning and poor stability during the welding process of the main frame of the cutting machine in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A welding positioning device for a cutting machine main frame comprises a bracket, a cutting machine support frame, a quick clamp, a support plate, a limit slider and a rotation positioning device, wherein a plurality of the quick clamps are installed on the bracket, the cutting machine support frame is installed between the left and right sides of the bracket, the support plates are installed on the cutting machine support frame and the bottom of the bracket, the support plates comprise a water tank support plate and a bracket support plate, the rotation positioning device comprises a rotation limit block and a rotation limit plate, the limit slider and the rotation limit block are installed on the bracket support plate, and the rotation limit plate is installed on the bracket.

[0007] Furthermore, the bracket is installed in the limiting groove of the bracket support plate through a supporting square tube, the supporting square tube and the bracket are connected through a plurality of rotating pins, and the supporting square tube and the bracket support plate are connected through a plurality of latches.

[0008] The supporting square tube is installed in the limit groove of the support plate of the bracket and connected to the bracket through multiple rotating pins. This design can ensure that the bracket maintains extremely high stability during the welding process, and can effectively prevent displacement or deformation even when subjected to large welding stress, thereby improving the stability and durability of the overall structure. The use of rotating pins allows the bracket to be fine-tuned within a certain range, which means that the position or angle of the bracket can be easily adjusted according to actual needs, increasing the flexibility of the device and the adaptability to different welding tasks, which is conducive to improving welding quality and efficiency. The supporting square tube is connected to the support plate of the bracket through multiple pins, realizing a fast and easy installation and disassembly process. This design reduces assembly time, facilitates maintenance and replacement of parts, and further improves production efficiency and operational convenience. The design of the limit groove ensures the precise installation position of the supporting square tube. Combined with the adjustment function of the rotating pin, extremely high positioning accuracy can be achieved during the initial installation, laying a solid foundation for subsequent welding operations and avoiding repeated work or quality problems caused by inaccurate positioning.

[0009] Furthermore, a slide rail is provided at the upper end of the supporting square tube, and the limiting slider is provided inside the slide rail.

[0010] The movement of the limit slider in the slide rail can achieve fine-tuning of the cutting machine main frame in the vertical direction, helping workers to accurately control the welding position, ensuring that each welding can achieve extremely high positioning accuracy, effectively reducing welding size deviations, and improving the quality and consistency of the finished product. Through the coordinated use of the slide rail and the limit slider, workers can quickly and intuitively adjust the support structure without the need for complex tools or a large amount of manpower intervention, simplifying the adjustment process, improving work efficiency, and reducing operating difficulty. The design of the slide rail can provide stable guidance and support for the limit slider, keeping it stable and without shaking during the adjustment process, ensuring the stability of the support structure even in high load or vibration environments, and improving the safety factor of the operation. The adjustability of the slide rail and the slider enables the device to adapt to cutting machine main frames of different sizes and shapes, improving the versatility and flexibility of the equipment, reducing the downtime adjustment time caused by changing workpieces, and improving the adaptability and production efficiency of the production line.

[0011] Furthermore, the rotation limiting plate is hinged to the supporting square tube through the rotation pin.

[0012] The hinged structure enables the rotating limit plate to rotate freely within a certain angle range. The operator can easily adjust the angle of the limit plate according to actual welding requirements, thereby achieving multi-angle and multi-directional precise positioning restrictions on the welded parts, improving the flexibility and adaptability of the welding operation. Through the connection of the rotating pin, the rotating limit plate can fit tightly and limit the position of the welded parts, ensuring that each welding can be performed at the preset optimal position, greatly improving the positioning accuracy of the welding point, reducing the scrap rate caused by inaccurate positioning, and improving product quality. Compared with the fixed limit device, this rotatable design simplifies the adjustment steps, and workers can quickly adjust the limit plate to the appropriate position without complex tools, thereby improving work efficiency and reducing labor intensity.

[0013] Furthermore, the water tank support plate includes a water tank front support plate and a water tank rear support plate, and the water tank front support plate and the water tank rear support plate are welded to the water tank support plate.

[0014] By dividing the water tank support into two parts, front and rear, and reinforcing them independently, the weight of the water tank can be distributed more evenly, effectively improving the load-bearing capacity of the overall structure. Especially when loading heavy water tanks, the stability and safety of the welding platform can be significantly increased, and deformation or damage caused by uneven force can be reduced. The independent front and rear support plates of the water tank make it easier to operate when the water tank needs to be maintained or replaced. The water tank and its supporting structure can be inspected or partially repaired more easily without affecting other parts of the entire welding platform, reducing maintenance costs and downtime. The split design gives the water tank support structure more flexibility, and can be customized and installed according to different models or sizes of water tanks, enhancing the versatility and adaptability of the device to meet the specific needs of different welding operations. By strengthening the structural design of the water tank support, the stability of the water tank during the welding process is ensured, reducing the potential safety hazards caused by the displacement or tipping of the water tank, and providing a safer working environment for the welding operator.

[0015] Furthermore, a handle is welded on the water tank support plate.

[0016] The handles welded on the water tank support plate provide direct gripping points, making it more convenient and labor-saving for operators to carry or install the water tank support plate, especially when the position of the water tank needs to be frequently adjusted or replaced, which can significantly improve work efficiency and reduce physical exertion. Carrying by the handle can avoid direct contact with the water tank or other welded components that may be hot, reduce the risk of burns or other safety accidents, and ensure the safety and health of operators. The handle design allows a single person to easily operate the movement and positioning of the water tank support plate without the assistance of additional tools, enhancing the flexibility and response speed of on-site operations, which is particularly important for scenarios that require rapid layout adjustments or emergency handling. During daily maintenance or regular inspections, the welded handles make it easier for workers to move the water tank support plate, so that they can approach and view the condition of the support plate and the area under or around the water tank, ensuring that potential problems are discovered and resolved in a timely manner.

[0017] The utility model has the following beneficial effects:

[0018] 1. By adopting a rotating positioning device combined with a limit slider and a rotating limit plate, the main frame is accurately positioned before welding, ensuring that each welding can achieve a consistent position and angle, significantly reducing the deviation of the welding size, improving the accuracy and quality of product assembly, and avoiding the problem of main frame skew caused by inaccurate welding position;

[0019] 2. The integrated quick clamp design enables the cutting machine support frame to be quickly and firmly fixed on the bracket, which not only reduces the assembly time, but also improves the working efficiency, facilitates the quick loading and unloading before and after welding, and solves the problems of inconvenient assembly and disassembly and low efficiency in traditional methods;

[0020] 3. The setting of the support plate (including the water tank support plate and the bracket support plate) enhances the stability and bearing capacity of the entire device, is suitable for the welding requirements of the main frame of the cutting machine of different specifications and weights, and improves the versatility and applicability of the equipment.
