Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a highly efficient automatic welding device and method for container corner fittings. Background Art

[0002] Container corner fittings are fixed parts that connect the trailer and the eight corners of the container during container transportation. Corner fittings play an important role in the stability of the transport container. To improve the stability of the corner fittings, it is necessary to optimize the corner fittings during processing.

[0003] At present, container corner fittings are generally produced by sand casting. Since the corner fitting casting process is restricted by size, thickness, climate, raw materials and production process, some corner fittings will have various casting defects such as sand holes, air holes, shrinkage holes, cross-sectional shrinkage, cracks, etc. In order to ensure the performance of the corner fittings, it is necessary to repair the defects of the corner fittings after production.

[0004] When performing repair welding of corner pieces, firstly, detect the position of defects on the corner pieces. Generally, laser scanning, X-ray detection, ultrasonic detection and visual detection are used to locate the position of defects on the corner pieces. Secondly, after determining the position of defects on the corner pieces, the corner pieces are sent to the repair welding equipment for repair welding. Common repair welding equipment mainly includes welding platform, installation fixture and welding robot. The installation fixture is set on the welding platform. The installation fixture clamps and fixes the corner pieces to be welded, and then the corresponding surfaces of the corner pieces are welded by the welding robot.

[0005] With regard to the above-mentioned related technologies, since the corner piece may have defects on multiple sides, after the welding robot completes the repair welding of one side of the corner piece, the corner piece needs to be removed from the mounting fixture, and then the posture of the corner piece is turned and re-clamped so that the welding robot can repair the other defective side of the corner piece. When there are many defective sides on the corner piece, the corner piece needs to be clamped repeatedly, which will affect the welding efficiency of the corner piece. Summary of the invention

[0006] The present application provides a highly efficient automatic repair welding device and method for container corner fittings, the purpose of which is to reduce the number of repeated clamping of the corner fittings when performing multi-sided repair welding on the corner fittings, thereby improving the repair welding efficiency of the corner fittings.

[0007] On the one hand, the present application provides a container corner piece high-efficiency automatic repair welding device adopts the following technical solution: A high-efficiency automatic repair welding device for container corner fittings, comprising a welding platform, a clamping mechanism and a welding robot, wherein the clamping mechanism is arranged on the upper side of the welding platform, and the welding robot is located on one side of the width direction of the welding platform; the clamping mechanism comprises a wide side clamping assembly and a long side clamping assembly, the wide side clamping assembly comprises a first electromagnetic suction plate, and the long side clamping assembly comprises a second electromagnetic suction plate, the first electromagnetic suction plate and the second electromagnetic suction plate are respectively used for magnetically fixing two adjacent side surfaces of the corner fitting, a first telescopic driving component is arranged on the first electromagnetic suction plate, and the first telescopic driving component is used to drive the first electromagnetic suction plate to move along the width direction of the welding platform, and a second telescopic driving component is arranged on the second electromagnetic suction plate, and the second telescopic driving component is used to drive the second electromagnetic suction plate to move along the length direction of the welding platform.

[0008] By adopting the above technical solution, the welding platform, the clamping mechanism and the welding robot cooperate, the clamping mechanism fixes the corner piece to the welding platform, and the welding robot performs the repair welding on the outer side of the corner piece, thereby satisfying the function of the repair welding device.

[0009] The clamping mechanism cooperates with the first electromagnetic suction plate, the first telescopic driving member, the second electromagnetic suction plate and the second telescopic driving member. Under the action of the first telescopic driving member, the first electromagnetic suction plate can fit or separate with the corner piece, and when the corner piece fits with the first electromagnetic suction plate, the first electromagnetic suction plate can magnetically fix the corner piece. Similarly, under the action of the second telescopic driving member, the second electromagnetic suction plate can fit or separate with the corner piece, and when the corner piece fits with the second electromagnetic suction plate, the second electromagnetic suction plate can magnetically fix the corner piece. Therefore, both the first electromagnetic suction plate and the second electromagnetic suction plate can realize the clamping function of the corner piece.

[0010] With the cooperation of the first telescopic driving member and the second telescopic driving member, the first electromagnetic suction plate or the second electromagnetic suction plate can be automatically selected to magnetically fix the corner piece. Since the first electromagnetic suction plate and the second electromagnetic suction plate magnetically fix different sides of the corner piece, when the first electromagnetic suction plate magnetically fixes the corner piece, five sides of the corner piece are exposed, and the welding robot can perform the repair welding process on the five exposed sides of the corner piece; and when the second electromagnetic suction plate magnetically fixes the corner piece, the side of the corner piece connected to the first electromagnetic suction plate is exposed, and the welding robot can perform the repair welding process on the remaining sides of the corner piece.

[0011] Therefore, the setting of the clamping mechanism enables repair welding of all sides of the corner piece when the repair welding device of the present application is used for repair welding of the corner piece, and the clamping mechanism can automatically realize repeated clamping of the corner piece, which can improve the repair welding efficiency of the corner piece.

The first rotating driving member is connected to the first telescopic driving member, and the first rotating driving member is used to drive the first telescopic driving member to rotate, and the second rotating driving member is connected to the second telescopic driving member, and the second rotating driving member is used to drive the second telescopic driving member to rotate.

[0013] By adopting the above technical solution, the first rotating driving member and the second rotating driving member are arranged, when the first electromagnetic suction plate or the second electromagnetic suction plate is magnetically fixed to the corner piece, the corresponding first rotating driving member or the second rotating driving member will drive the corresponding first telescopic driving member or the second telescopic driving member to rotate, thereby causing the corresponding first electromagnetic suction plate or the second electromagnetic suction plate to rotate, which enables the corner piece fixed by magnetic attraction to rotate as well.

[0014] The corresponding first rotating drive member or the second rotating drive member rotates, driving the angle piece to rotate 90° or 180° clockwise or counterclockwise, which enables the angle piece to be adjusted at multiple angles, providing a more flexible operating space for the welding robot, thereby improving the flexibility and coverage of the repair welding operation, and further improving the repair welding efficiency and quality.

[0015] Optionally, the welding robot includes a robot body, a mounting pipe rack and a welding head, the mounting pipe rack is located above the welding platform, the length direction of the mounting pipe rack is arranged along the width direction of the welding platform, one end of the mounting pipe rack in the length direction is connected to the robot body, and the other end is provided with a clearance hole, the clearance hole is used to accommodate corner pieces, the welding head is arranged on a side of the mounting pipe rack where the clearance hole is opened, and the working end of the welding head is arranged toward the central axis of the clearance hole.

[0016] By adopting the above technical solution, the welding robot cooperates with the robot body, the mounting pipe rack and the welding head. The robot body, the mounting pipe rack and the welding head are connected in sequence, which meets the function of the welding robot and can perform repair welding on corner parts.

[0017] The installation pipe rack is located on the welding platform, and a clearance hole is provided at one end of the installation pipe rack, and the clearance hole can accommodate the corner piece. Therefore, when the robot body drives the installation pipe rack to be arranged opposite to the first electromagnetic suction plate or the second electromagnetic suction plate, the robot body drives the installation pipe rack to move toward the corresponding first electromagnetic suction plate or the second electromagnetic suction plate, and the corner piece magnetically fixed on the first electromagnetic suction plate or the second electromagnetic suction plate will automatically be inserted into the clearance hole, and the welding head will then perform repair welding on the side corresponding to the corner piece. The design of the installation pipe rack allows the welding robot to weld different sides of the corner piece by adjusting the position of the installation pipe rack without moving the corner piece, thereby reducing the number of clamping times for the corner piece and improving the degree of automation of the repair welding operation.

Therefore, the robot body cooperates with the covering driving member to increase the movement range of the welding head, so that the range of the welding head that can be repaired covers the corresponding side of the corner piece, which can improve the repair welding effect of the welding head on the corner piece.
