Description

Technical Field

[0001] The utility model relates to the technical field of visual detection devices, in particular to a welding molten pool detection device based on visual sensing. Background Art

[0002] During melting welding, under the action of the heat source, the liquid metal part with a certain shape formed on the weldment is called the welding molten pool. During the arc welding process, the molten pool metal under the arc overcomes gravity and surface tension and is discharged to the tail of the molten pool under the action of the arc force. As the arc moves forward, the metal at the tail of the molten pool cools and crystallizes to form a weld. The shape of the weld is determined by the shape of the molten pool, which is related to the form and spatial position of the joint, the shape and size of the groove and gap, the edge of the base material, the melting of the wire metal, the transition method of the molten droplet, etc. Different welding process methods and specification parameters will result in different molten volume and molten pool length. In order to detect the length of the molten pool at the weld, a visual welding molten pool detection mechanism is required to detect the welding molten pool at the weld;

[0003] Existing detection devices usually fix the detection mechanism and the welding head to facilitate the detection of the welding molten pool. When the detection mechanism is damaged and needs to be repaired, it is inconvenient to disassemble and repair it. At the same time, a certain amount of noise will be generated during welding. The noise in the environment will have a certain impact on the accuracy of the detection mechanism, making it difficult to correctly identify the state of the molten pool. In response to the above problems, the inventor proposes a welding molten pool detection device based on visual sensing to solve the above problems. Utility Model Content

The two side ends of the placement box 28 are symmetrically fixedly connected with side blocks 36 near the center. A sliding shaft 37 is slidably connected with the center of the side block 36. The bottom ends of the two sliding shafts 37 and near the center of the placement box 28 are symmetrically fixedly connected with L-limiting plates 310. The bottom end of the placement box 28 is detachably connected with a base 32, and the top ends of the two L-limiting plates 310 are in contact with the inside of the bottom end of the base 32. A detection component 33 is provided at the top of the base 32 and located inside the placement box 28, and a detection probe 34 is fixedly connected to the bottom end of the detection component 33.

[0021] A through hole 35 is formed at the center of the base 32 , and the diameter of the through hole 35 is larger than the diameter of the detection probe 34 .

[0022] By adopting the above technical solution, a through hole 35 is provided at the center of the base 32 to facilitate the installation and use of the detection probe 34 .

[0023] A pressure plate 38 is fixedly connected to the outer ring of the sliding shaft 37 and located below the side block 36 . A spring 39 is sleeved and fixedly connected to the outer ring of the sliding shaft 37 at the top of the pressure plate 38 . The top of the spring 39 is fixedly connected to the side block 36 .

[0024] By adopting the above technical solution, the pressure plate 38 is provided to support and fix the spring 39, and the spring 39 is provided to reset it.

[0025] A welding head 26 is fixedly connected at the center of the bottom end of the slide plate 25, and an illuminating lamp 27 is fixedly connected at one end of the L-plate 23 away from the placement box 28 and near the bottom.

[0026] By adopting the above technical solution, a lighting lamp 27 is provided at one side end of the welding head 26 in order to illuminate the molten pool below, thereby facilitating the operation of the detection probe 34 .

[0027] An electric cylinder 24 is fixedly connected to the center of the inner wall at the bottom end of the L-plate 23 , and an output end of the electric cylinder 24 is fixedly connected to the slide plate 25 .

[0031] Working principle: When the device is in use, first place the welded part at the center above the placement plate 11 and limit it, then operate the driving slide 22, so that the L plate 23 slides, so that the welding head 26 can achieve the effect of horizontal movement, and then operate the electric cylinder 24, so that the fixedly connected slide plate 25 is lowered under the action of the side wall of the L plate 23, so that the welding head 26 can then weld the welded part, and cooperate with the lighting lamp 27 and the detection probe 34 to realize the detection of the welding molten pool. By arranging silencer cotton 31 on the two side walls of the placement box 28 and the bottom end of the top cover 3, noise reduction is achieved, so that the noise generated can be prevented from affecting the detection work. The detachable top cover 3 is to facilitate the replacement of the silencer cotton 31, thereby solving the problem that a certain amount of noise is generated during welding, wherein the noise in the environment will have a certain impact on the accuracy of the detection mechanism, making it difficult to correctly identify the state of the molten pool;

[0032] When it is necessary to repair the detection part 33 inside the placement box 28, the two pressure plates 38 are pressed downward at the same time, so that the fixedly connected sliding shaft 37 drives the L limit plate 310 to move downward, thereby disengaging the two L limit plates 310 from the limiting work on the base 32. After the replacement is completed, it can be reset, and the force of the two pressure plates 38 is released. With the cooperation of the spring 39, the sliding shaft 37 drives the L limit plate 310 to rise, thereby realizing the limiting work on the base 32, thereby solving the problem of fixed installation of the detection mechanism and the welding head 26, and making it inconvenient to disassemble and repair when the detection mechanism is damaged and needs to be repaired.
