Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding device, in particular to a welding device for container corner fittings. BACKGROUND

[0002] Corner fittings are widely used in factory, warehouse shelves, shelves, tool shelves, workbenches, simple grating, display sheds and home air conditioning racks, beds, decoration, etc. The top corners of the container are also fixedly connected with corner fittings. During the transfer and fixation of the container, the position of the container is changed by the connection of the lifting appliance and the corner fittings.

[0003] In the production and manufacturing of containers, the combination and connection of various workpieces are basically carried out by welding. Usually, the beam frame, corner fittings, etc. are welded into a cuboid frame in advance, and then the shell is welded, and finally the paint is sprayed and other equipment is installed. Although the types of containers are relatively few, mainly 20-foot containers and 40-foot containers, but in the production process, according to the specific scene of application, the structure still has differences. The existing container welding equipment mostly adopts welding manipulator, but when welding different types of containers, the position of the welding manipulator still needs to be changed, so as to increase the welding operation range, which is relatively not flexible. SUMMARY

[0004] In order to solve the above problems, the present application discloses a welding device for container corner fittings, which comprises a workbench, a plurality of stop blocks are fixedly connected to the upper end edge of the workbench, welding mechanisms are arranged on both sides of the workbench, and a plurality of fixing mechanisms are arranged on the upper end of the workbench. The workpiece is placed on the workbench and fixed by the fixing mechanism, and then the welding mechanism is used for welding and combining the workpiece.

[0005] The welding mechanism comprises a sliding block, a light rod is inserted into the middle of the sliding block, a rack is arranged above the sliding block, the light rod and the rack are fixedly connected with the workbench, a second motor is fixedly connected to the side wall of the sliding block, a gear is fixedly connected to the output end of the second motor and engaged with the rack, and a welding manipulator is fixedly connected to the upper end of the sliding block. When welding the container, the welding of the beam frame is carried out in advance, and then the welding of the iron sheet is carried out. The beam and the corner fitting of the container are placed on the workbench, the U-shaped structure is pre-welded, and then the welding is further carried out to form a cuboid frame, that is, the welding is carried out in steps. In the production of the container, in order to increase the structural strength of the container, a plurality of connecting rods are additionally arranged between the beams. At this time, the welding manipulator is fixedly connected to the sliding block, the second motor is started, the position of the welding manipulator is changed, and therefore after the welding of the beam and the corner fitting is completed, the welding manipulator can be moved to weld other parts. The number of welding manipulators can be reduced, and the welding operation is more flexible.

[0006] Preferably, a first motor is fixedly connected to the lower end of the slider, and an unwinding wheel is sleeved on the output end of the first motor. Welding wire is wound on the unwinding wheel, and a nut is provided at the output end of the first motor. By tightening the nut, the unwinding wheel is fixed on the output end of the first motor. When the welding robot is performing welding operations, the first motor also moves accordingly, that is, the unwinding wheel rotates and releases the wound welding wire.

[0007] Preferably, a horizontal plate is fixedly connected to one side of the slider, and a first electric cylinder is fixedly connected to the upper end of the horizontal plate. A first telescopic rod extends from the upper end of the first electric cylinder, and the upper end of the first telescopic rod is fixedly connected to the bottom of the welding robot. The welding robot is a multi-joint type, and the addition of the first electric cylinder and the first telescopic rod allows the welding robot to move up and down, expanding its working range. Relatively speaking, while maintaining the same working range, the inclusion of the first electric cylinder and the first telescopic rod can reduce the number of joints in the welding robot to some extent, thus lowering costs.

[0008] Preferably, the fixing mechanism includes a second electric cylinder, the output of which is fixedly connected to a second telescopic rod. A fixing member is fixedly connected to the end of the second telescopic rod, and the fixing member faces the workpiece. The corner piece is placed at the corner of the work platform, and then the beam piece is placed on the edge of the work platform, with the beam piece abutting against the stop block. After the position is determined, the second electric cylinder is activated, the second telescopic rod extends, and the fixing member at its end abuts against the beam piece, thereby fixing the beam piece.

[0009] The beneficial effects of this invention are as follows: The invention includes a second motor, a rack, and a guide rod, enabling the slider to move axially along the guide rod. Simultaneously, the invention includes a first electric cylinder and a first telescopic rod, allowing for adjustments to the working height of the welding robot. These features significantly increase the working range of the welding robot and enhance welding flexibility. Attached Figure Description
