[0002] In modern industrial production, base plate welding is a key step in the product manufacturing process. Its welding quality directly determines the overall structural strength and stability of the product, which in turn affects the product's performance and safety. However, traditional base plate welding devices have shown obvious limitations when dealing with diverse production needs, especially in positioning and fixation.

[0003] Traditional base plate welding devices generally rely on fixed fixtures or positioning structures. The original intention of the design of these structures is to provide stable and accurate positioning for base plates of specific sizes to ensure the smooth progress of the welding process. However, with the rapid development of the manufacturing industry and the diversification of product types, the sizes of base plates that need to be welded are also becoming increasingly diversified. At this time, fixed fixtures or positioning structures are stretched. When the size of the base plate to be welded changes, users of traditional devices often need to manually replace fixtures or perform cumbersome positioning structure adjustments. This process not only takes a lot of time and energy, but also increases the difficulty of operation, greatly reducing production efficiency. What is more serious is that due to the errors and uncertainties of manual adjustments, positioning accuracy is often difficult to guarantee, which further affects the welding quality and the overall performance of the product.

[0041] The motor 51 on the same side is fixedly connected to the shell 521, and the output end of the motor 51 passes through the outer surface of the shell 521 and extends to the inner cavity of the shell 521. The output end of the motor 51 is fixedly connected to the gear 522. The clamping assembly 54 includes a main rod 541. A slide groove 3 542 is opened on the upper part of the main rod 541. A plurality of rubber blocks 543 are fixedly connected to one side of the main rod 541. A slider 1 544 is symmetrically fixedly connected to the lower end of the main rod 541. The outer surface of the slider 1 544 on the same side is slidably connected to the inner cavity of the slide groove 2 41.

During the movement of the clamping assembly 54, the slider 1 544 will slide in the inner cavity of the slide groove 2 41.

[0043] Example 3

[0044] like Figure 8As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the limit assembly 6 includes a slider 2 61, the outer surface of the slider 2 61 on the same side is slidably connected to the inner cavity of the slide groove 3 542, the upper side of the slider 2 61 close to the rubber block 543 is fixedly connected with a connecting block 2 62, the connecting block 2 62 is threadedly connected with a threaded rod 1 63, the upper side of the slider 2 61 away from the connecting block 2 62 is fixedly connected with a connecting block 3 64, and the connecting block 3 64 is threadedly connected with a threaded rod 2 65.

After the limit assemblies 6 are moved to the appropriate position, the threaded rod 2 65 is rotated to move the lower end of the threaded rod 2 65 toward the main rod 541. Then, the position of the limit assemblies 6 can be limited by the cooperation between the threaded rod 2 65 and the main rod 541. Then, the threaded rod 1 63 is rotated to move the lower end of the threaded rod 1 63 toward the base plate. The threaded rod 1 63 is used to apply a force to the upper end of the base plate, thereby limiting the position of the upper end of the base plate. This can reduce or even avoid the situation where the upper part of the base plate is lifted up when the clamping assembly 54 positions and fixes the side wall of the base plate, thereby improving the accuracy of the base plate positioning and the quality of base plate welding.

[0046] Example 4

[0047] like Figure 4 , Figure 5 As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, a slide groove 2 41 is symmetrically opened on the upper part of the placement block 4, a connecting block 1 42 is symmetrically fixedly connected to the lower end of the placement block 4, a hydraulic cylinder 43 is fixedly connected to the middle part of the lower end of the placement block 4, the lower end of the hydraulic cylinder 43 is fixedly connected to the upper end of the support plate 1, a slide groove 31 is opened in the middle part of the support block 3, and the inner cavity of the slide groove 31 on the same side is slidably connected to the outer surface of the connecting block 42.

[0048] In this embodiment, the hydraulic cylinder 43 is then controlled by the controller to operate, and the placement block 4 is driven to rise and fall by the extension and contraction of the hydraulic cylinder 43, thereby driving the connecting block 42 to slide in the inner cavity of the slide groove 31, and then the distance between the floor and the welding gun is adjusted according to the thickness of the base plate. After the positioning and clamping of the base plate are completed, the base plate can be welded by the welding machine 2.

[0049] The working principle of the bottom plate welding device with a positioning structure will be described in detail below.

[0050] like Figure 1-8As shown, when the bottom plate needs to be welded, first, the bottom plate to be welded is placed on the upper end surface of the placement block 4, and then the motor 51 is controlled to operate by the controller, and the output end of the motor 51 is used to drive the gear 522 to rotate, so that the gear 522 can mesh with the adjacent rack 1 523 and rack 2 524, and drive the rack 1 523 and rack 2 524 to move. At the same time, under the action of the connecting rod 53, the gear 522 on the other side will be driven to rotate, and then the gear 522 on the other side will be driven to mesh with the adjacent rack 1 523 and rack 2 524, and drive the rack 2 524 and rack 2 524 to move. Under the cooperation of the two driving components 52, the two clamping components 54 can be driven to move toward the bottom plate, and then under the push of the main rod 541, a number of rubber blocks 543 will be driven to position and fix the bottom plate. During the movement of the clamping component 54, the slider 1 544 will slide in the inner cavity of the slide groove 2 41.

[0051] Then, by sliding a plurality of limit assemblies 6, the positions of the plurality of limit assemblies 6 on the clamping assembly 54 are adjusted according to the length and welding position of the base plate. When the plurality of limit assemblies 6 are moved to a suitable position, the threaded rod 2 65 is rotated to allow the lower end of the threaded rod 2 65 to move toward the main rod 541. Then, the position of the limit assemblies 6 can be limited by the cooperation between the threaded rod 2 65 and the main rod 541. Then, by rotating the threaded rod 1 63, the lower end of the threaded rod 1 63 is moved toward the base plate. The threaded rod 1 63 is used to apply a force to the upper end of the base plate, thereby limiting the position of the upper end of the base plate. This can reduce or even avoid the situation where the upper part of the base plate is lifted up when the clamping assembly 54 is used to position and fix the side wall of the base plate, thereby improving the accuracy of the base plate positioning and the quality of base plate welding.

[0052] Then, the hydraulic cylinder 43 is controlled by the controller to operate, and the placement block 4 is driven to rise and fall by the extension and contraction of the hydraulic cylinder 43, so as to drive the connecting block 42 to slide in the inner cavity of the slide groove 31, and then the distance between the floor and the welding gun is adjusted according to the thickness of the bottom plate. After the positioning and clamping of the bottom plate are completed, the bottom plate can be welded by the welding machine 2.

[0053] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
