Description

Technical Field

[0001] This utility model relates to the field of plate welding support technology, and in particular to a plate welding support structure. Background Technology

[0002] In the sheet metal welding process of the machinery manufacturing industry, multiple sheets of sheet metal are usually spliced ​​and welded on a tooling table according to the designed positions. Existing sheet metal welding support structures mostly rely on manual placement of positioning blocks, pressure blocks, or hoisting configuration blocks to temporarily fix the sheets, and use magnetic clamps or spot welding for positioning to prevent the sheets from shifting or warping during the welding process.

[0003] However, before the sheet metal is placed on the platform, a large number of positioning blocks, clamping blocks, or partitions still need to be arranged and hoisted in advance. The steps are cumbersome and the process cycle is long. This not only increases the intensity of operation and the risk of positioning errors, but also takes up tooling preparation time and affects the accessibility of the welding area, thereby reducing the turnover efficiency of the workstation and the overall production cycle. Utility Model Content

[0004] Therefore, it is necessary to provide a sheet metal welding support structure to address the problem that a large number of positioning blocks, clamping blocks, or partitions still need to be pre-arranged and hoisted before the sheet metal is placed on the platform. This is a cumbersome process with a long cycle time, which not only increases the intensity of operation and the risk of positioning errors, but also takes up tooling preparation time, affects the accessibility of the welding area, and thus reduces the turnover efficiency of the workstation and the overall production cycle time.

[0005] A plate welding support structure includes: a support frame, on the top of which two welding stations are fixedly installed; and a welding fixing mechanism for fixing and supporting the welding of the plate, which is disposed on one side of the welding stations; wherein the welding fixing mechanism includes a bidirectional pump fixedly installed on one side of the support frame, a fixing component is disposed on one side of the bidirectional pump, and a support component is disposed on one side of the two welding stations.

[0006] The fixing assembly includes two guide plates fixedly installed inside the support frame. The two guide plates are respectively located at the bottom of two welding stations. Multiple suction cups are provided on the top of each guide plate. The multiple suction cups extend to the top of the adjacent welding station. Movable tubes are fixedly installed at the bottom of each suction cup. A regulating valve is fixedly installed on one side of the bidirectional pump. A first connecting pipe is fixedly installed on one side of the regulating valve. The first connecting pipe is fixedly connected to a diversion pipe. The diversion pipe is fixedly connected to multiple movable tubes on both sides.

[0007] The diversion pipe is internally connected to the adjacent movable pipe. Multiple sealing pipes are fixedly installed on the top of the guide plate. The multiple sealing pipes are located on the outside of the multiple movable pipes, and the movable pipes are slidably connected to the adjacent sealing pipes. A second connecting pipe is fixedly connected to the other side of the regulating valve. The second connecting pipe is internally connected to the two guide plates.

[0008] A sealing ring is fixedly installed on the top of the suction cup, and a welding platform extends from the top of the sealing tube.

[0009] The two guide plates are interconnected, and the sealing tube is connected to the interior of the adjacent guide plate.

[0010] The regulating valve is configured in a T-shape and is fixedly connected to the support frame.

[0011] The support assembly includes components fixedly mounted on a contact plate, with multiple suction cups penetrating the contact plate.

[0012] Multiple rubber balls are rotatably mounted on the top of the contact plate, and the multiple rubber balls are equidistantly distributed.

[0013] Beneficial effects 1. The fixing component can form a negative pressure adsorption on the bottom surface of the plate after it is placed on the welding table. It can quickly and stably fix the plate without the need for additional blocks, reduce pre-welding preparation, reduce displacement and positioning errors, and improve welding accuracy and efficiency. The support component supports and guides the plate when the fixing component is not working, which facilitates smooth movement and fine-tuning of position, and improves workstation turnover and operation convenience. 2. When the plate is placed on the rubber balls, the rotation of the balls provides low-friction rolling support for the plate, which facilitates the pushing and precise adjustment of the plate position before adsorption. When the suction cup starts vacuum adsorption, the plate presses down and squeezes the rubber balls, putting the rubber balls into a compressed and stationary state, firmly fixing the plate in the predetermined position and preventing movement during the welding process.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes the plate welding support structure.

[0019] In one embodiment, a plate welding support structure includes: a support frame 100, with two welding stations 200 fixedly installed on the top of the support frame 100; and a welding fixing mechanism 300, which is disposed on one side of the welding station 200 for fixing and supporting welding of the plate. The welding fixing mechanism 300 includes a bidirectional pump 310 fixedly installed on one side of the support frame 100, a fixing component 320 disposed on one side of the bidirectional pump 310, and a support component 330 disposed on one side of the two welding stations 200.

[0020] In this embodiment, the fixing component 320 can form a negative pressure adsorption on the bottom surface of the plate after it is placed on the welding table 200, so as to quickly and stably fix the plate without the need for additional hanging configuration blocks, significantly reducing the pre-welding preparation process, reducing the risk of plate displacement and positioning error, and improving welding positioning accuracy and efficiency. When the fixing component 320 is not working, the support component 330 can support and guide the plate, making it easier for the operator to move the plate smoothly and make fine adjustments to its position, further improving the turnover speed and operation convenience of the workstation. It should be noted that existing plate welding support structures typically include basic components such as a support frame, welding table, positioning and clamping components, and guide and limiting components. These components provide load-bearing, positioning, and support during the plate welding process. The fixing component 320 uses a bidirectional pump 310 to achieve negative pressure adsorption and fixation of the plate, while the support component 330 supports and guides the plate when the fixing component 320 is not in operation or when the adsorption is released. Since both components are located at the edge of the welding table 200 and are independently startable and stopable, maintaining a necessary distance from the working surface of the welding table 200, they will not obstruct the weld area or interfere with the normal use of existing support devices.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 320 includes two guide plates 321 fixedly installed inside the support frame 100. The two guide plates 321 are respectively located at the bottom of the two welding stations 200. Multiple suction cups 324 are provided on the top of each guide plate 321. The multiple suction cups 324 extend to the top of the adjacent welding station 200. Movable tubes 323 are fixedly installed at the bottom of the suction cups 324. A regulating valve 326 is fixedly installed on one side of the bidirectional pump 310. A first connecting pipe 327 is fixedly installed on one side of the regulating valve 326. A diversion pipe 328 is fixedly connected to the first connecting pipe 327. The diversion pipe 328 is fixedly connected to multiple movable tubes 323 on both sides.

[0022] In this embodiment, by setting a guide plate 321 inside the support frame 100 and arranging multiple suction cups 324 extending through to the surface of the welding table 200 on its top, and cooperating with the vacuum pipeline consisting of a bidirectional pump 310, a regulating valve 326, a first connecting pipe 327 and a diversion pipe 328, multiple movable pipes 323 can simultaneously supply negative pressure to the suction cups 324, thereby achieving rapid and uniform negative pressure adsorption and fixation of the plate placed on the welding table 200. This eliminates the cumbersome operation of placing pressure blocks, positioning blocks or hoisting configuration blocks required by traditional welding fixtures, significantly shortening the pre-welding preparation time and reducing labor intensity. It should be noted that the bidirectional pump 310 is a dual-purpose vacuum pressure pump capable of both extracting and injecting gas. Its inlet is connected to the distributor pipe 328, the movable pipe 323, and the suction cup 324, used to create negative pressure during operation to adsorb and fix the plate. Its outlet is connected to the sealing pipe 322 via the regulating valve 326 and the second connecting pipe 329, used to inject gas into the sealing pipe 322 to drive the movable pipe 323 to rise and fall relative to each other, thereby adjusting the height and contact state of the suction cup 324. The bidirectional pump 310 can be a commercially available small vacuum compressor integrated pump, diaphragm vacuum pump, rotary vane vacuum pump, or pneumatic vacuum pressure pump, or other pump types with comparable functions can be selected as needed.

[0023] The diversion pipe 328 is internally connected to the adjacent movable pipe 323. Multiple sealing pipes 322 are fixedly installed on the top of the guide plate 321. The multiple sealing pipes 322 are all located outside the multiple movable pipes 323, and the movable pipes 323 are slidably connected to the adjacent sealing pipes 322. A second connecting pipe 329 is fixedly connected to the other side of the regulating valve 326. The second connecting pipe 329 is internally connected to the two guide plates 321.

[0024] In this embodiment, a sealing tube 322 is provided on the top of the guide plate 321 and forms a sliding fit with the movable tube 323. At the same time, the second connecting tube 329 is connected to the bidirectional pump 310 and the regulating valve 326, realizing the function of both drawing air to generate negative pressure for adsorption and injecting gas to drive the movable tube 323 to rise and fall in the same set of pipelines. The two working modes of negative pressure adsorption and air pressure rise and fall can be flexibly switched by simply adjusting the regulating valve 326. It can not only quickly fix plates of different thicknesses and shapes, but also quickly release adsorption and lift the suction cup 324 after welding, which is convenient for the handling and fine adjustment of the plate.

[0025] A sealing ring 325 is fixedly installed on the top of the suction cup 324, and a welding station 200 extends from the top of the sealing tube 322.

[0026] In this embodiment, after the plate is placed on the welding table 200, the bidirectional pump 310 generates negative pressure on the suction cup 324 through the diversion pipe 328 and the movable pipe 323. At the same time, under the action of the sealing ring 325, a stable seal is formed, which quickly fixes the plate in the predetermined position. When it is necessary to release or adjust, the bidirectional pump 310 is switched to inject gas into the sealing pipe 322 through the regulating valve 326, which drives the movable pipe 323 to rise and fall relative to the sealing pipe 322, releases the negative pressure and lifts the suction cup 324, so as to realize the rapid release and height adjustment of the plate.

[0027] The two guide plates 321 are interconnected, and the sealing tube 322 is connected to the interior of the adjacent guide plate 321.

[0028] In this embodiment, the bidirectional pump 310 can supply or extract air to the guide plate 321 and the sealing pipe 322 as a whole through the regulating valve 326, which can simultaneously drive multiple movable pipes 323 to move up and down synchronously.

[0029] The regulating valve 326 is T-shaped and is fixedly connected to the support frame 100.

[0030] In this embodiment, the T-shaped structure of the regulating valve 326 allows it to be connected to the bidirectional pump 310, the first connecting pipe 327, and the second connecting pipe 329 simultaneously. It can flexibly switch or adjust the two working conditions of negative pressure suction and positive pressure air injection through a single valve body, thereby achieving unified control of the movable pipe 323 and the suction cup 324. It should be noted that the regulating valve 326 is an integrated T-shaped three-way valve, whose three ports are connected to the bidirectional pump 310, the first connecting pipe 327 and the second connecting pipe 329 respectively. It can quickly switch between negative pressure suction and positive pressure injection by rotating or tossing the valve core, or adjust the flow rate of the air passages on both sides as needed.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the support assembly 330 includes a contact plate 331 that is fixedly mounted, and a plurality of suction cups 324 that penetrate the contact plate 331.

[0032] In this embodiment, the surface of the contact plate 331 is made smooth to reduce surface friction when placing the plate, which facilitates the plate to slide smoothly, adjust its position, and align with the welding station before adsorption.

[0033] Multiple rubber balls 332 are rotatably mounted on the top of the contact plate 331, and the multiple rubber balls 332 are evenly distributed.

[0034] In this embodiment, when the plate is placed on the rubber ball 332, the rotation of the ball can achieve low-friction rolling support for the plate, which facilitates the pushing and precise adjustment of the plate position before adsorption. When the suction cup 324 starts vacuum adsorption, the plate presses down and squeezes the rubber ball 332, so that the rubber ball 332 is in a compressed and stationary state, thereby increasing the contact resistance and cooperating with the negative pressure of the suction cup 324 to firmly fix the plate in the predetermined position and avoid movement during the welding process.

[0035] Working principle: When in use, the plate is first placed on two welding tables 200. The plate initially rests on the contact plate 331 and rubber ball 332 of the support component 330. With the help of the smooth surface treatment and the low friction support of the ball, it can be easily pushed, aligned with the seam, and the position can be finely adjusted. Subsequently, the bidirectional pump 310 is controlled by the regulating valve 326 to operate, drawing air into the suction cup 324 through the diversion pipe 328 and the movable pipe 323 to form a negative pressure. The sealing ring 325 cooperates with the bottom surface of the plate to produce a stable seal and adsorption, realizing the quick and uniform fixation of the plate without the need for hanging and placing the configuration block. During the welding process, the rubber ball 332 is squeezed and stationary due to the pressure of the plate, increasing the contact resistance and preventing displacement in conjunction with the negative pressure of the suction cup 324. When welding is completed or adjustment is required, simply switch the regulating valve 326 to inject gas into the sealing pipe 322 by the bidirectional pump 310, driving the movable pipe 323 to rise and fall relative to each other and release the negative pressure. The suction cup 324 is lifted, and the plate can be easily released or moved again. The whole process realizes the rapid switching between negative pressure adsorption and air pressure release, improving positioning accuracy, operation convenience and workstation turnover efficiency.

[0036] It should be noted that the bidirectional pump and regulating valve mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the bidirectional pump and regulating valve can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
