Description

An automated welding platform Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and specifically relates to an automated welding platform. Background Technology

[0002] Welding fixtures are process devices used to fix and position welding workpieces, ensuring welding accuracy and efficiency. Welding fixtures use mechanical devices to fix the workpiece, preventing displacement caused by thermal deformation or external forces during welding, and ensuring the accuracy of the weldment's dimensions and shape. The welding platform, a type of universal platform used with welding fixtures, is a specialized worktable that supports the workpiece and assists in the welding operation.

[0003] Existing welding fixtures, when welding two planar raw materials, require welding the front side first, then flipping the material to weld the back side. For example, a multi-functional welding platform (publication number CN205702976U) uses a cylinder to drive a clamping roller to clamp the raw material before welding. However, after welding the front side, the material still needs to be flipped, re-clamped, and then welded on the back side. This process requires two welding operations and two clamping operations, resulting in low overall efficiency. Similarly, an automated bracket welding platform (publication number CN210649291U) uses a servo motor and a rotary table to increase the flexibility of the welding worktable and equipment, expand the welding range, and avoid dead angles during welding. However, after welding the front side, the material still needs to be flipped, re-clamped, and then welded on the back side. This process also requires two welding operations and two clamping operations, resulting in low overall efficiency. Summary of the Invention

[0004] To address the assembly error caused by secondary clamping of welded workpieces in the existing technology, this utility model provides an automated welding platform that avoids secondary clamping through double-sided welding and improves welding efficiency. The specific technical solution is as follows: An automated welding platform includes two mounting platforms 1 and two gantry welding machines 2.

[0010] The automated welding platform of this utility model has the following advantages compared with the prior art:

[0011] 1. This automated welding platform uses two welding machines to weld the welding material simultaneously, allowing the workpiece to be welded on both the front and back sides after a single clamping, greatly improving welding efficiency. Furthermore, this invention only requires one clamping, thus avoiding the errors caused by secondary clamping of the workpiece and improving welding accuracy.

[0021] Working principle:

[0022] I. Preparation and Installation Before Use: Before using this utility model, an external AC power supply needs to be connected to this utility model to provide energy for the electrical appliances in this utility model. Then, the operator connects the matching controller to this utility model to provide control and working logic for the operation of the two gantry welding devices 2, the clamp hydraulic device 6, and the moving drive motor 9 in this utility model. Finally, a computer capable of recognizing drawings is connected to this utility model to provide computing power for the utility model to recognize drawings.

[0023] II. Operating Procedure and Working Principle: The operator first reads the drawing of the workpiece using a computer, which can identify the outer contours and welding lines of the two workpieces. Identifying the outer contours allows for adjustment of the relative position of the fixture fixing seats 5, facilitating subsequent clamping of the workpiece. Specifically, the computer controls the moving drive motor 9 to rotate according to the drawing via a controller. The rotation of the moving drive motor 9 drives the moving drive screw 8 to rotate, and through the action of the screw, the moving drive connecting frame 10 moves linearly outside the moving drive screw 8. Simultaneously, the moving square rod 4 drives the fixture fixing seats 5 to move. At this time, all the fixture fixing seats 5 are arranged according to the outer contour of the workpiece. Then, the operator places the workpiece on the upper wall of several fixture fixing seats 5 and starts clamping. The fixture hydraulic device 6 drives the fixture clamping plate 7 to extend until the fixture clamping plate 7 can clamp the workpiece with the fixture fixing seats 5. The workpiece is clamped, and the two gantry welding machines 2 weld simultaneously, completing the welding of the front and back of the workpiece at the same time.
