Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding equipment for the production of wastewater treatment equipment. Background Technology

[0002] In the production process of wastewater treatment equipment, welding is one of the key manufacturing processes. Wastewater treatment equipment is usually composed of a variety of metal parts, which need to be connected into a complete equipment structure through welding to ensure the equipment's sealing, stability and functionality.

[0003] With the advancement of technology, laser welding technology, as an advanced welding method, has advantages such as high welding precision, small heat-affected zone, and fast welding speed. It has been widely used in the production of wastewater treatment equipment. Laser welding equipment uses the high energy density of the laser beam to rapidly melt the welding part and form a strong weld, which can effectively improve welding quality and production efficiency. In laser welding equipment, the focusing lens is one of the core optical components. The performance of the focusing lens directly affects the focusing effect of the laser beam, and thus affects the welding quality.

[0004] However, during laser welding, the welding torch generates a large amount of heat. Since the focusing lens is located inside the welding torch and is exposed to high temperatures for extended periods, it undergoes thermal expansion and deformation. To maintain the focusing effect of the laser beam, the focusing lens needs to be replaced. However, the current method for replacing the focusing lens in welding equipment used in wastewater treatment plants is complex, requiring the disassembly of numerous components. This is not only time-consuming but also increases the risk of equipment damage. Furthermore, during the focusing lens replacement process, the welding torch's mounting slot is open, allowing dust and impurities from the external environment to easily enter the welding torch. These dust and impurities adhere to the laser beam transmission path, absorbing or scattering laser energy, affecting the quality and stability of the laser beam, and potentially contaminating and damaging other optical components inside the welding torch, thus impacting the overall performance of the laser welding equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding device for the production of wastewater treatment equipment, which has the advantage of facilitating quick replacement of the focusing lens. This solves the problem that the existing welding devices for wastewater treatment equipment production involve complex operations and are not convenient for quick replacement of the focusing lens.

[0006] This utility model provides the following technical solution: a welding device for the production of wastewater treatment equipment, comprising a welding gun and a focusing lens, wherein a first connecting assembly is provided between the focusing lens and the welding gun, the first connecting assembly includes a mounting groove formed on the top surface of the welding gun, a first guide rod is symmetrically fixedly connected inside the welding gun, a first mounting frame and a second mounting frame are provided inside the welding gun, both the inner wall surfaces of the first mounting frame and the second mounting frame are provided with fixing grooves, a guide block is fixedly connected to the bottom side wall surface of the first mounting frame, a first spring is sleeved on the surface of each of the first guide rods, a second connecting assembly is provided between the first mounting frame and the second mounting frame, and a snap-fit ​​assembly is provided inside the first mounting frame. The first connecting assembly serves to connect the welding gun and the focusing lens, enabling the focusing lens to be stably mounted on the welding gun and facilitating the replacement of the focusing lens.

[0007] Preferably, the focusing lens is movably connected inside the fixing groove, the first guide rods are all fixedly connected between the inner wall surfaces of the mounting groove, the first mounting bracket is slidably connected to the surface of the first guide rod through the guide block, the first spring is fixedly connected between the guide block and the opposite surface of the mounting groove, and the focusing lens focuses the laser beam so that the laser beam can accurately act on the welding part, ensuring the quality and effect of the welding.

[0008] Preferably, the second connecting component includes second guide rods uniformly fixedly connected to the four bottom corners of the second mounting bracket, guide holes uniformly opened at the four corners of the top surface of the first mounting bracket, connecting grooves opened on the opposing surfaces of the first and second mounting brackets, and second springs uniformly arranged between the opposing surfaces of the first and second mounting brackets. The second guide rods are uniformly fixedly connected to the four bottom corners of the second mounting bracket and slidably connected to the guide holes on the top of the first mounting bracket, providing guidance for the sliding of the second mounting bracket and ensuring the stability of the second mounting bracket when it moves relative to the first mounting bracket.

[0009] Preferably, the first mounting bracket and the second mounting bracket are vertically slidably connected inside the mounting groove. The second mounting bracket is slidably connected inside the guide hole via the second guide rod. The second springs are fixedly connected between the inner wall surfaces of the connecting groove. The second mounting bracket is disposed inside the welding gun, opposite to the first mounting bracket. It also has a fixing groove inside for engaging the top edge of the focusing lens, so that the focusing lens is stably fixed between the two mounting brackets. The second mounting bracket is connected to the first mounting bracket via the second connecting assembly, which enables relative movement with the first mounting bracket.

[0010] Preferably, the snap-fit ​​assembly includes a snap-fit ​​groove formed on the surface of the first mounting bracket, snap-fit ​​blocks are symmetrically slidably connected inside the first mounting bracket, and a third spring is symmetrically arranged between the opposing surfaces of the two snap-fit ​​blocks. The snap-fit ​​groove is formed on the surface of the first mounting bracket to provide sliding space for the snap-fit ​​blocks and also to accommodate the third spring.

[0011] Preferably, the locking blocks are slidably connected to each other inside the locking groove, and the third springs are all disposed inside the locking groove. The locking blocks are symmetrically slidably connected to the locking grooves inside the first mounting bracket. After the focusing lens is completely pulled out from inside the welding gun, due to the action of the third springs, the two locking blocks slide out relative to each other and lock onto both sides of the top surface of the mounting groove, preventing the first and second mounting brackets from retracting into the mounting groove under the action of the first springs. At the same time, it plays a role in temporarily sealing the mounting groove when replacing the focusing lens.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of the first connecting component, the second connecting component, and the snap-fit ​​component, the process of replacing the focusing lens becomes simple and efficient. Simply pull the second mounting bracket upward to sequentially complete the operations of pulling out the focusing lens, snap-fit ​​fixing, separating the mounting bracket, taking out the focusing lens and inserting the new focusing lens, resetting the mounting bracket, and resetting the snap-fit ​​block. This greatly shortens the time required to replace the focusing lens, improves the maintenance efficiency of the equipment, reduces the downtime caused by focusing lens problems, and helps to ensure the continuity and stability of wastewater treatment equipment production.

[0014] 2. Through the synergistic action of the first connecting component, the second connecting component, and the snap-fit ​​component, during the replacement of the focusing lens, the snap-fit ​​blocks are snapped onto both sides of the top surface of the mounting slot, temporarily sealing the mounting slot. This effectively reduces the possibility of dust from the external environment entering the welding gun through the mounting slot, thereby ensuring a relatively clean internal environment for the welding gun. This ensures that the laser beam can be focused stably and accurately, thus guaranteeing the welding quality of wastewater treatment equipment components and improving product reliability and service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 4This utility model provides an embodiment of a welding device for wastewater treatment equipment production, comprising a welding torch 1 and a focusing lens 2. A first connecting assembly 3 is provided between the focusing lens 2 and the welding torch 1. The first connecting assembly 3 includes a mounting groove 31 formed on the top surface of the welding torch 1. A first guide rod 32 is symmetrically fixedly connected inside the welding torch 1. A first mounting frame 33 and a second mounting frame 34 are provided inside the welding torch 1. Fixing grooves 35 are formed on the inner wall surfaces of both the first mounting frame 33 and the second mounting frame 34. A guide block 36 is fixedly connected to the bottom side wall surface of the first mounting frame 33. A first spring 37 is sleeved on the surface of each of the first guide rods 32. A connection is provided between the first mounting frame 33 and the second mounting frame 34. There is a second connecting component 38. A snap-fit ​​component 39 is provided inside the first mounting bracket 33. The focusing lens 2 is movably connected inside the fixing groove 35. The first guide rods 32 are all fixedly connected between the inner wall surfaces of the mounting groove 31. The first mounting bracket 33 is slidably connected to the surface of the first guide rods 32 via a guide block 36. The first spring 37 is fixedly connected between the guide block 36 and the opposing surfaces of the mounting groove 31. The welding gun 1 is used for laser welding of components of the wastewater treatment equipment and is the core component for achieving the welding function. The mounting groove 31 is opened on the top surface of the welding gun 1, providing space for the installation and sliding of the first mounting bracket 33 and the second mounting bracket 34. It also facilitates the operation during the replacement of the focusing lens 2. The channel, with the first guide rod 32 symmetrically fixedly connected inside the welding gun 1, provides guidance for the sliding of the first mounting bracket 33, ensuring that the first mounting bracket 33 slides vertically within the mounting groove 31. Simultaneously, the first spring 37 is sleeved on the first guide rod 32, and the first guide rod 32 guides the extension and retraction of the first spring 37. The first mounting bracket 33 is slidably connected to the first guide rod 32 via a guide block 36. An internal fixing groove 35 is provided for placing the focusing lens 2. Additionally, a snap-fit ​​assembly 39 is provided inside the first mounting bracket 33, which serves to snap and fix the focusing lens 2 and temporarily seal the mounting groove 31 during replacement. The fixing groove 35 is formed on the inner wall surface of the first mounting bracket 33 and the second mounting bracket 34, for placing... The focusing lens 2 is fixed to ensure its stable position during welding. A guide block 36 is fixedly connected to the bottom sidewall surface of the first mounting bracket 33 and slidably connected to the first guide rod 32, allowing the first mounting bracket 33 to slide stably along the first guide rod 32. Simultaneously, the guide block 36 is connected to a first spring 37, transmitting the elastic force of the first spring 37. The first spring 37 is sleeved on the surface of the first guide rod 32 and fixedly connected between the guide block 36 and the opposing surfaces of the mounting groove 31. During the replacement of the focusing lens 2, the first spring 37 is compressed and stores elastic potential energy. When the locking block 392 resets, the first spring 37 releases its elastic potential energy, causing the first mounting bracket 33 and the second mounting bracket 34 to retract into the mounting groove 31.

[0022] Please see Figure 1 - Figure 4 The second connecting assembly 38 includes second guide rods 381 evenly fixedly connected to the four bottom corners of the second mounting bracket 34. Guide holes 382 are evenly provided at the four corners of the top surface of the first mounting bracket 33. Connecting grooves 383 are provided on the opposing surfaces of the first mounting bracket 33 and the second mounting bracket 34. Second springs 384 are evenly disposed between the opposing surfaces of the first mounting bracket 33 and the second mounting bracket 34. The first mounting bracket 33 and the second mounting bracket 34 are vertically slidably connected inside the mounting groove 31. The second mounting bracket 34 is slidably connected inside the guide holes 382 via the second guide rods 381. The second springs 384 are all fixedly connected between the inner wall surfaces of the connecting grooves 383. The snap-fit ​​assembly 39 includes snap-fit ​​grooves 391 formed on the surface of the first mounting bracket 33. Snap-fit ​​blocks 392 are symmetrically slidably connected inside the first mounting bracket 33. Third springs 393 are symmetrically arranged between the opposing surfaces of the two snap-fit ​​blocks 392. The snap-fit ​​blocks 392 are slidably connected to each other inside the snap-fit ​​grooves 391. The third springs 393 are all located inside the snap-fit ​​grooves 391. The elastic force of the second springs 384 is greater than that of the first springs 37. Guide holes 382 are evenly formed on the top of the first mounting bracket 33. The four corners of the surface cooperate with the second guide rod 381 to realize the sliding of the second mounting bracket 34 on the first mounting bracket 33. The connecting groove 383 is opened on the opposite surface of the first mounting bracket 33 and the second mounting bracket 34 to fix the second spring 384 and provide installation space for the second spring 384. The second spring 384 is evenly distributed between the opposite surfaces of the first mounting bracket 33 and the second mounting bracket 34 and is fixedly connected between the inner wall surfaces of the connecting groove 383. The elastic force of the second spring 384 is greater than that of the first spring 37. When changing the focusing lens 2, the second mounting bracket 34 is pulled upward. The second spring 384 drives the first mounting bracket 33 to move upward. When the second mounting bracket 34 is released, the second spring 384 drives the second mounting bracket 34 to reset, so that the fixing groove 35 inside the second mounting bracket 34 engages with the top edge of the focusing lens 2. The third spring 393 is symmetrically arranged between the opposing surfaces of the two locking blocks 392, located in the locking groove 391. The third spring 393 applies pressure to the locking blocks 392, so that the locking blocks 392 can engage with both sides of the top surface of the mounting groove 31. When it is necessary to reset the locking blocks 392, press the locking blocks 392 to compress the third spring 393.

[0023] Working Principle: In the welding equipment used in the production of wastewater treatment equipment, welding gun 1 welds the components of the wastewater treatment equipment. During the long-term laser welding process of welding gun 1, a large amount of heat is generated, placing the focusing lens 2 in a high-temperature environment. Prolonged exposure to high temperatures causes thermal expansion and deformation of the focusing lens 2, affecting the focusing effect of the laser beam and the welding quality. Therefore, the focusing lens 2 needs to be replaced. When replacing the focusing lens 2, first pull the second mounting bracket 34 upwards. Because the elastic force of the second spring 384 is greater than that of the first spring 37, pulling the second mounting bracket 34 upwards, under the connection between the second spring 384 and the first mounting bracket 33 and the second mounting bracket 34, will cause the first mounting bracket 33 to move upwards during installation. As the groove 31 moves upward, the first mounting bracket 33 drives the guide block 36 to slide upward on the surface of the first guide rod 32. Simultaneously, the movement of the first guide rod 32 applies pressure to the first spring 37, causing it to contract and store elastic potential energy. This then pulls the focusing lens 2 out of the welding gun 1. Once the focusing lens 2 is completely withdrawn from the welding gun 1, the two locking blocks 392, due to the action of the third spring 393, apply pressure to each other, causing them to slide relative to each other inside the locking groove 391. The two locking blocks 392 are then pushed out by the third spring 393 and locked onto both sides of the top surface of the mounting groove 31, preventing the first mounting bracket 33 and the second mounting bracket 34 from collapsing when the focusing lens 2 is replaced. Under the action of spring 37, the guide block 36 retracts into the mounting slot 31. Simultaneously, under the action of springs 37 and 393, the top surface of the guide block 36 abuts against the top inner wall surface of the mounting slot 31, and the bottom surfaces of the two locking blocks 392 lock onto both sides of the top surface of the mounting slot 31. This temporarily seals the mounting slot 31 when the focusing lens 2 is replaced, reducing the amount of dust from the external environment entering the welding gun 1 through the mounting slot 31 during the replacement of the focusing lens 2. Then, the second mounting bracket 34 is pulled upwards, causing it to move upwards. The second guide rod 381 slides inside the guide hole 382, ​​and the second spring 384 stretches, temporarily separating the second mounting bracket 34 from the first mounting bracket 33. At this point, the focusing lens 2 can be removed from the first mounting slot 31. The new focusing lens 2 is then placed inside the fixing slot 35 of the first mounting bracket 33. The focusing lens 2 is a convex lens. To facilitate correct placement, the edge of the fixing slot 35 near the convex surface of the focusing lens 2 is rounded. Then, the second mounting bracket 34 is released, and under the action of the second spring 384, it resets, causing the fixing slot 35 inside the second mounting bracket 34 to engage with the top edge of the focusing lens 2, ensuring the focusing lens 2 is stably engaged inside the fixing slot 35. Simultaneously, the two engaging blocks 392 are pressed into the engaging slot 391, compressing the third spring 393.When both locking blocks 392 are fully inserted into the locking slots 391, the first spring 37, through the first guide rod 32, causes the first mounting bracket 33 and the second mounting bracket 34 to retract into the mounting slots 31, thus completing the replacement of the focusing lens 2.
