Problems solved by technology

[0002] Anchor chains and mooring chains are widely used in marine ships, petroleum and other industries. The usual manufacturing method for the crosspieces on the chain links of anchor chains and mooring chains is to press the crosspieces when the chain link is 600-700°C. If not implemented Welding is easy to loosen during use
At present, for the crosspieces that need to be welded, manual welding is usually used in the factory, and carbon dioxide shielded welding is used for manual welding. There are the following problems: 1. Carbon dioxide gas is harmful to workers; 2. Manual welding efficiency is low; 3. For large quantities It is difficult to guarantee the equal quality of welds produced by manual welding
However, due to the relatively long length of the anchor chain and mooring chain, up to 1000m or more, there are many product specifications, the crosspiece diameter ranges from 12.5mm to 157mm, and the self-weight is huge, and the repair chain is a combination of flexibility and rigidity , causing difficulties in its transmission and positioning; for these reasons, there is currently no mature automatic welding system for anchor chain and mooring chain crosspiece welding

Embodiment 1

[0039] The device includes a transverse straight conveyor chain plate 1 and a right-angle conveyor chain plate 2 formed by connecting a transverse chain plate 21 and a longitudinal chain plate 22. 1 parallel and located directly below the linear conveying chain plate; one end of the linear conveying chain plate is the feeding end, and the end of the longitudinal chain plate 22 of the right-angle conveying chain plate is the discharging end; several Feed roller 4; a welding robot 3 with visual servo is arranged on the inner side of the intersection of the transverse chain plate 21 and the longitudinal chain plate 22; The laser scanner 5 at the crosspiece position of chain link worker A; the device also includes a control system 6 that can receive the signal of the laser scanner and control the actions of the linear conveyor chain plate, the right angle conveyor chain plate and the welding robot. The side guide rails 7 with adjustable spacing are arranged on both sides of the co...

Embodiment 2

[0052] On the basis of the first embodiment, in addition to the original first welding robot 3a, a second welding robot 3b is installed on the side of the longitudinal chain plate of the right-angle conveying chain plate.

[0053] The welding control steps of this embodiment are: step 1, use the laser scanner above the linear conveyor chain plate to position the chain link crosspiece located at the upper welding station; at the same time, use the laser scanner above the longitudinal chain plate to position the lower welding The chain link crosspiece of the station is positioned;

[0054] Step 2: Control the first welding robot to position and weld the weld on the arc on the inner side of the front side of the link at the upper welding station; at the same time control the second welding robot to position and weld the inner side of the link at the lower welding station The welding seam on the side arc is positioned and welded;

[0055] Step 3, the chain drives one section forw...

Embodiment 3

[0059] On the basis of the second embodiment above, a third welding robot 3c is set on the other side of the linear conveying chain plate 1 opposite to the first welding robot 3a, and the first welding robot and the third welding robot are in the conveying direction At the same time, a fourth welding robot 3d is set on the other side of the longitudinal chain plate 22 relative to the second welding robot 3b, and the second welding robot and the fourth welding robot are staggered by a certain distance in the conveying direction. distance.

[0060] The welding process of this embodiment is to control the first welding robot and the third welding robot to locate and weld the welding seam on the inner side and the outer arc of the chain link front of the upper floor welding station respectively; The welding robot and the fourth welding robot position and weld the welding seams on the inner and outer arcs of the chain link reverse side of the lower welding station respectively.
