Description

Technical Field

[0001] The present invention relates to the technical field of intelligent welding systems, and more specifically, to a welding device for shaft parts with real-time weld monitoring function. Background Art

[0002] An intelligent welding system is an innovative manufacturing system that combines advanced technologies such as artificial intelligence, robotics, sensor technology, automatic control technology, and machine vision with traditional welding processes. It is driving the manufacturing industry towards more efficient, precise, and intelligent directions. It usually includes parts such as welding robots, welding power sources, sensors, control systems, and software, and can automatically adjust the welding trajectory through real-time monitoring and feedback to ensure the stability and consistency of welding quality. For example: The prior art with Chinese patent application number 202411506391.4 and patent theme name of an automatic welding photoelectric contact type weld tracking detection system can be combined with welding robots, automatic arc welding machines, plasma arc welding machines, etc. to form an intelligent welding system, achieving real-time monitoring of welds. Among them, when welding shaft parts, an auxiliary device needs to be combined with the intelligent welding system to enable the intelligent welding system to weld the weld more conveniently. For example: The Chinese patent application number 201520357083.X with the patent theme name of an adjustable shaft part welding fixture can fix two short shafts and align the welds of the two short shafts, and the intelligent welding system can weld the welds of the two short shafts. However, for some shaft parts with a length greater than five meters, in order to save materials, the common method is to weld two short shafts to a section of round pipe, and the short shafts are welded to the ends of the round pipe. Due to the relatively long length of the five-meter shaft part, if the positioning method (horizontal positioning) in the prior art (Chinese patent application number 201520357083.X) is used, the occupied space is relatively large, and after the shaft part is fixed, the shaft part cannot move, resulting in the need to change the position of the shaft part during welding, with relatively low welding efficiency and relatively poor flexibility in use.

[0015] In order to make the content easier to understand clearly, the following will be further described in detail according to specific embodiments in conjunction with the drawings; A welding device for shaft parts with real-time weld monitoring function solves the technical problems in the related art of relatively large occupied space, relatively low welding efficiency, and relatively poor flexibility in use, and achieves the positive effects of relatively small occupied space, relatively high welding efficiency, relatively good welding quality, and relatively good flexibility in use. The general idea is as follows: Embodiment 1: As Figure 1 、 Figure 2 、 Figure 15 shown; A welding device for shaft parts with real-time weld monitoring function includes: A vertical support frame 10, the bottom of which is connected to the ground foundation 100, and the middle position of the vertical support frame 10 has a vertical space 11; A horizontal support frame 20, connected to the top of the vertical support frame 10; A ladder 30, connected to one side wall of the vertical support frame 10; A lifting platform 40, connected to the ground foundation 100 and arranged in the vertical space 11; An electric chuck 50, connected to the top of the lifting platform 40 and arranged in the vertical space 11, used to clamp one end of the round tube 200 and drive the round tube 200 to rotate; At least two rotatable guiding and supporting members 60, spaced and connected to the vertical support frame 10 and arranged in the vertical space 11, used to guide and support the middle position of the round tube 200; A movable upper pressing member 70, connected to the horizontal support frame 20, used to press the short shaft 300 after the short shaft 300 is inserted into the other end of the round tube 200; And a weld monitoring and welding part 80, connected to the vertical support frame 10, used to weld the weld 400 at the insertion part of the short shaft 300 and the round tube 200 and monitor the weld 400 (the weld 400 is an annular weld); Specifically, during implementation, the vertical support frame 10 and the horizontal support frame 20 form a reliable support structure, which is beneficial to connecting and arranging other components. And since there is a vertical space 11 in the middle position of the vertical support frame 10 after the vertical support frame 10 and the horizontal support frame 20 are combined, when arranging other components at the vertical space 11, the vertical space is fully utilized, and the occupied space is relatively small; The ladder 30 is beneficial for the operator to climb, can see the situation of the weld 400, and monitor the situation at the weld 400, and the flexibility in use is relatively good; Use a traveling crane to hoist the circular pipe 200 (hoisting the circular pipe 200 with a traveling crane is common knowledge). The circular pipe 200 vertically enters the vertical space 11. The circular pipe 200 gradually contacts the rotatable guiding and clamping member 60 and moves downward along the rotatable guiding and clamping member 60. When approaching the electric chuck 50, the circular pipe 200 stops moving downward. The lifting platform 40 operates, driving the electric chuck 50 to move towards the circular pipe 200. After the electric chuck 50 clamps the circular pipe 200, release the circular pipe 200, and the circular pipe 200 detaches from the traveling crane. The traveling crane continues to hoist the short shaft 300. Until after the short shaft 300 is inserted into the circular pipe 200, release the short shaft 300, and the short shaft 300 detaches from the traveling crane. The lifting platform 40 operates again, driving the electric chuck 50, the circular pipe 200, and the short shaft 300 to move, adjusting the position of the weld 400 (the purpose is to make the position of the weld 400 conducive to welding by the weld monitoring welding part 80). Move the position of the movable upper pressing member 70. The movable upper pressing member 70 presses the short shaft 300. The weld monitoring welding part 80 welds the weld 400. And during welding, the electric chuck 50 drives the circular pipe 200 and the short shaft 300 to rotate. The welding efficiency is relatively high, and the weld is monitored in real time, and the welding quality is relatively good; Embodiment 2: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 12 shown; During implementation, after the vertical support frame 10 is projected onto a plane from top to bottom, its outer shape is a triangular structure, which is relatively beautiful in appearance and can form a reliable support structure; The vertical support frame 10 includes: three columns 10-1, which are arranged at intervals to form a triangular arrangement; a first intermediate support member 10-2, which is connected between the columns 10-1, close to the ground foundation 100, and surrounds the lifting platform 40; a second intermediate support member 10-3, which is connected between the columns 10-1, is spaced from the first intermediate support member 10-2, and has the lifting platform 40, the electric chuck 50, and the rotatable guiding and clamping member 60 between it and the first intermediate support member 10-2.
