Description

Technical Field

[0001] The utility model belongs to the technical field of water tank body processing, in particular to a device for removing laser welding slag from a water tank body. Background Art

[0002] A water tank is a kind of water tank used to store domestic water or production water in a production workshop. Water tanks, especially water tanks used for industrial production, are mostly large in size and are used to store water that can meet the production needs of the workshop.

[0003] Therefore, unlike traditional small water tanks, the processing of large water tanks is not only complicated, but also time-consuming. This is reflected in the fact that during the processing of large water tanks, the water tanks often need to be welded to ensure that the water tanks have a high degree of sealing. Among them, laser welding is currently a common welding method in water tank processing. However, after laser welding, a certain amount of welding slag is likely to form on the tank body, and the cooled welding slag solidifies at the weld position (the solidification force is not particularly high and can be removed with a shovel). It needs to be cleaned before subsequent polishing and grinding can be carried out.

[0004] The more conventional removal method is to manually use a shovel to clean it little by little along the length of the weld. Although the cleaning is relatively smooth, during the processing, since the weld is circumferential (the tank body is composed of multiple sections of sealed welding), when cleaning to the position where the tank body contacts the workbench, the tank body needs to be turned over, and the tank body is relatively heavy and not easy to turn over.

[0005] Moreover, the above method has a disadvantage in that it is difficult to control the force during the cleaning process. If the force is too strong, the tank body may be easily damaged, while if the force is too weak, the welding slag may not be completely cleaned. Therefore, in actual work, the welding slag position can only be repeatedly and carefully scraped and cleaned to ensure that the welding slag is completely cleaned. However, this method is too inefficient and is obviously not compatible with the assembly line operation in the workshop, which seriously reduces production efficiency. Utility Model Content

[0036] Example 1

[0037] like Figure 1-5 As shown, a device for removing laser welding slag from a water tank body comprises a water tank body rolling mechanism 1 which is spaced apart at front and rear ends. The water tank body rolling mechanisms 1 are assembled and connected via a length adjustment mechanism. The total length of the spacing between the water tank body rolling mechanisms 1 can be adjusted via the length adjustment mechanism according to the different lengths of the water tank bodies.

[0038] Specifically, in this way, the spacing of the water tank body rolling mechanism 1 is adjusted according to the total length of the tank body, ensuring that tank bodies of different lengths can be fully supported.

[0039] Specifically, the specific structure of the water tank body rolling mechanism 1 is as follows: the water tank body rolling mechanism 1 includes a turning frame 13 arranged at a front and rear interval, and a driving roller 12 is rotatably connected between the central parts of the turning frame 13 (the top surface of the driving roller 12 is higher than the top position of the turning frame 13 to ensure that the tank body and the turning frame 13 maintain a safe distance), and a driving motor 14 is assembled and connected to the driving roller 12.

[0040] Specifically, according to the conventional method, the above-mentioned turning frame 13 is respectively fixedly connected with a mounting seat, and the two ends of the driving roller 12 are respectively fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the turning frame 13 and the mounting seat 2 (according to the conventional method, the turning frame 13 and the mounting seat 2 are installed with an adaptor bearing, and similarly, the two ends of the following rollers are respectively fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the bearing on the turning frame 13). Several bottom mounting plates are welded on the mounting seat 2 (according to the existing method, the bottom mounting plate-bolt structure is used to realize the whole device being fixedly mounted on the workbench).

[0041] The output shaft of the driving motor 14 is mounted on the rotating shaft through a connecting flange to achieve detachability. At the same time, the motor is fixedly mounted on the mounting seat 2 through a motor mounting frame.

[0042] In order to effectively support the tank body, the water tank body rolling mechanism 1 further includes two rollers 11 rotatably connected between the turning frames 13; the rollers 11 are located on both sides of the driving roller 12. During the turning process, the tank body is supported and placed on the top of the driving roller 12, and both sides of the lower end of the tank body are supported on the rollers 11. The rollers 11 and the driving rollers 12 are arranged in a triangle.

[0043] The advantage of the above arrangement is that when the tank body is supported and placed on the top of the driving roller 12, the bottom of the tank body can be fully and stably supported on the rollers 11. Under the synchronous operation of the front and rear motors, the heavy tank body can be turned over synchronously from the front and rear sides. Specifically, the tank body is turned over under friction drive. When turning over, the weld seam on the tank body constantly adjusts its position, which makes it easier to remove the welding slag on the weld seam.

[0044] Example 2

[0045] like Figure 1-5 As shown, based on the structure of Example 1, in the process of dealing with tanks of different lengths, in order to ensure that both sides of the tank are supported and flipped in an evenly force manner, the length adjustment mechanism 3 includes a plurality of adjustment shafts 32 fixedly connected to the flipping frame 13 on one side, and a sleeve sleeved on the adjustment shaft 32 is fixedly connected to the flipping frame 13 on the opposite side, and a positioning screw 33 fastened to the adjustment shaft 31 is threadedly connected to the sleeve, and a plurality of through holes matching the positioning screw 33 are opened on the adjustment shaft 32.

[0046] During the working process, the length of the tank body is measured in advance, the mounting base 2 is randomly loosened from the workbench, and the spacing between the water tank body rolling mechanisms 1 on both sides is adjusted by sliding, and the positioning screw 33 is screwed onto the sleeve again and penetrated through the through holes at different positions, and then a reinforcing nut is fastened at the bottom position to achieve fixation. Then the mounting base 2 is fixed and installed again.

[0047] Example 3

[0048] like Figure 1-5 As shown, based on the structure of Example 1, in order to remove the welding slag in a very efficient manner during the welding slag removal process, the above-mentioned water tank body laser welding slag removal device also includes a scraper mechanism 4 respectively assembled and connected to the water tank body rolling mechanism 1.

[0049] Specifically, the scraper mechanism 4 comprises a long tool rod 41 , and a long scraper 42 for scraping off welding slag is assembled and connected to the bottom of the long tool rod 41 .

[0050] Specifically, the long scraper 42 is a rectangular scraper, and its bottom is polished. The front and rear ends of the long tool rod 41 are respectively slidably connected with an adjusting screw 43 fixedly installed on the water tank body tumbling mechanism 1 (specifically: the adjusting screw 43 is fixedly connected to the top of the turning frame 13), and the adjusting screw 43 is threadedly connected with a pair of nuts 431 for adjusting the height of the long tool rod 41 (specifically: the front and rear ends of the long tool rod 41 are respectively threadedly connected with a short screw, and the short screw is fixedly connected with a sliding sleeve 411 that is slidably adjusted on the adjusting screw 43, and the nuts are positioned at the top and bottom of the sliding sleeve 411. Loosening the nuts 411 can slide and adjust the spacing. After the spacing is adjusted, the nuts 411 can be positioned on both sides of the sliding sleeve 411). By adjusting the height of the long tool rod 41, the scraping force between the long scraper 42 and the welding slag can be adjusted according to the thickness of the welding slag.

[0051] Specifically, during the operation, after the operator loosens the nut 431, the operator slides the long tool rod 41 downward until the scraper 42 on the long tool rod 41 contacts the welding slag on the tank body, and adjusts the force of the long tool rod 41-scraper 42 contacting the welding slag according to the thickness of the welding slag, thereby achieving full removal of the welding slag. Since the tank body is in a rolling state, this method can achieve rapid removal, and since the distance between the scraper 42 and the tank body is fixed, after adjusting the distance between the scrapers, it can be removed over a large area without obstacles.

[0052] Furthermore, in actual use, when the thickness of the welding slag is relatively large, the distance between the scraper 42 and the tank body is gradually reduced to remove the welding slag in a gentle manner and protect the welding position.

[0053] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
