DETAILED DESCRIPTION

[0018] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0019] Please refer to Figure 1-Figure 8, is an embodiment of a welding test platform provided by the present invention, which can be used for the evaluation of deep-sea connector welding technology; it includes a loading device 100, a multifunctional welding platform 200, a multifunctional back plate 300, a clamping structure 400 and a enclosure 700; wherein, the loading device 100 can load the first test piece 500 and the second test piece 600 to the multifunctional welding platform 200, and after the multifunctional welding platform 200 adjusts the first test piece 500 and the second test piece 600 to the welding position, it cooperates with the clamping structure 400 to clamp and position the first test piece 500 and the second test piece 600; during the welding process, the multifunctional back plate 300 can collect and record welding information.

[0020] The loading device 100 can be a linear conveyor such as a crawler loading machine; the material preparation personnel only need to correctly place the first test piece 500 and the second test piece 600 in the loading area. When welding, the loading device 100 will transfer the first test piece 500 and the second test piece 600 to the multifunctional welding platform 200, avoiding manual handling after hoisting. Furthermore, the loading device 100 is provided with a limiting device such as a limiting plate to facilitate positioning of the first test piece 500 and the second test piece 600, ensuring that the first test piece 500 and the second test piece 600 are delivered to the multifunctional welding platform 200 in the designed posture.

[0021] The loading device 100 can also use other existing loading equipment, such as a manipulator, a crane and other equipment, to transfer the first test piece 500 and the second test piece 600 to the set position of the multifunctional welding platform 200; but compared with the linear conveyor, the structure is complex and the cost of use is high.

[0022] Please refer to Figure 2 and Figure 3 The multifunctional welding platform 200 includes a first workbench 201 and a second workbench 202, which are arranged side by side, and a weld gap 203 is provided between the first workbench 201 and the second workbench 202. When the feeding device 100 adopts a linear conveyor, the extension direction of the weld gap 203 is consistent with the conveying direction of the feeding device 100; the working surfaces of the first workbench 201 and the second workbench 202 are flush with the conveying surface of the feeding device 100, and the feeding device 100 feeds the first test piece 500 and the second test piece 600 to the first workbench 201 and the second workbench 202 respectively, and the welds of the first test piece 500 and the second test piece 600 correspond to the weld gap 203.

[0023] Please refer to Figure 4 and Figure 5 The first workbench 201 and the second workbench 202 are both provided with a specimen adjustment mechanism for adjusting the first specimen 500 and the second specimen 600 conveyed by the loading device 100 to a set welding position.

[0024] The specimen adjustment mechanism includes a plurality of first transverse AGV blocks 210 and a plurality of second transverse AGV blocks 217 , which are used to adjust the transverse positions of the first specimen 500 and the second specimen 600 .

[0025] Specifically, a first guide groove 213 concave toward the inner side is provided on the working surface of the first workbench 201, and a second guide groove 216 concave toward the inner side is provided on the working surface of the second workbench 202. The first guide groove 213 and the second guide groove 216 extend transversely, that is, parallel to the weld gap 203; a plurality of first transverse AGV blocks 210 are arranged in the first guide groove 213 and can move transversely along the first guide groove 213; a plurality of second transverse AGV blocks 217 are arranged in the second guide groove 216 and can move transversely along the second guide groove 216. The plurality of first transverse AGV blocks 210 cooperate together to drive the first test piece 500 to move transversely and adjust the transverse position of the first test piece 500 to the set welding position; a plurality of second transverse AGV blocks 217 can drive the second test piece 600 to move transversely and adjust the transverse position of the second test piece 600 to the set welding position.

[0026] In order to meet the adjustment requirements of the longitudinal positions of the first test piece 500 and the second test piece 600 , the test piece adjustment mechanism further includes a plurality of first longitudinal movement AGV blocks 214 and a plurality of second longitudinal movement AGV blocks 215 .

[0027] Specifically, a plurality of third guide grooves 209 are provided on the working surface of the first workbench 201, the third guide grooves 209 are concave toward the inner side of the first workbench 201, and extend longitudinally; a plurality of first longitudinal AGV blocks 214 are arranged in the third guide grooves 209, and can move longitudinally relative to the third guide grooves 209. A plurality of fourth guide grooves 219 are provided on the working surface of the second workbench 202, the fourth guide grooves 219 are concave in the working surface of the second workbench 202, and extend longitudinally; a plurality of second longitudinal AGV blocks 215 are located in the fourth guide grooves 219, and can move longitudinally relative to the fourth guide grooves 219.

[0028] Based on the small longitudinal displacement adjustment amount of the first test piece 500 and the second test piece 600 , in actual applications, each third guide groove 209 may only be provided with one first longitudinal displacement AGV block 214 , and each fourth guide groove 219 may also be provided with one second longitudinal displacement AGV block 215 .

[0029] Preferably, the number of the third guide groove 209 and the number of the fourth guide groove 219 are both two. When in use, the two first longitudinal movement AGV blocks 214 cooperate to provide multi-point stable support for the first specimen 500, drive the first specimen 500 to move longitudinally, and adjust the longitudinal position of the first specimen 500 to the set welding position; the two second longitudinal movement AGV blocks 215 cooperate with each other to provide multi-point stable support for the second specimen 600, drive the second specimen 600 to move longitudinally, and adjust the longitudinal position of the second specimen 600 to the welding position.

[0030] In practical applications, it is possible to consider setting the third guide groove 209 in the middle of the first guide groove 213, and the fourth guide groove 219 in the middle of the second guide groove 216; in view of the space requirements of the structural layout, preferably, the two third guide grooves 209 are respectively located at the two ends of the first guide groove 213, and the two fourth guide grooves 219 are located at the two ends of the second guide groove 216. The span between the two third guide grooves 209 and the span between the two fourth guide grooves 219 are large, which can form a stable and reliable support on the lower side of the first specimen 500 and the second specimen 600.

[0031] Furthermore, the third guide groove 209 is connected to the first guide groove 213, and the fourth guide groove 219 is connected to the second guide groove 216; not only is the structure compact, but also the processing technology of the third guide groove 209, the first guide groove 213, the fourth guide groove 219, and the second guide groove 216 can be simplified.

[0032] In order to better guide the movement of the first transverse AGV block 210 and the second transverse AGV block 217, a first guide platform 212 extending laterally is provided in the first guide groove 213, and a second guide platform 218 extending laterally is provided in the second guide groove 216. Similarly, a third guide platform and a fourth guide platform can also be provided in the third guide groove 209 and the fourth guide groove 219, respectively, as required.

[0033] After the first test piece 500 and the second test piece 600 are loaded and arrive at the multifunctional welding platform 200, the test piece adjustment mechanism will take over the transmission of the first test piece 500 and the second test piece 600. The first transverse AGV block 210, the second transverse AGV block 217, the first longitudinal AGV block 214 and the second longitudinal AGV block 215 are prior art, having existing structures and functions such as a walking system, a communication module and a navigation module. The present invention does not improve the structures of the second transverse AGV block 217, the first transverse AGV block 210, the first longitudinal AGV block 214 and the second longitudinal AGV block 215. In order to support the test piece, an electromagnetic adsorption platform is fixed on the first transverse AGV block 210, the second transverse AGV block 217, the first longitudinal AGV block 214 and the second longitudinal AGV block 215, and an electromagnet is arranged in the electromagnetic adsorption platform; when the position of the first test piece 500 and the second test piece 600 needs to be adjusted, the electromagnet is controlled to be energized to adsorb the first test piece 500 and the second test piece 600 on the electromagnetic adsorption platform, so that they move synchronously with the electromagnetic adsorption platform.

[0034] The first workbench 201 and the second workbench 202 are both installed using a floating support structure. The floating support structure can be used to adjust the angle between the working surface of the first workbench 201 and the working surface of the second workbench 202 to meet the operational requirements of different welding conditions.

[0035] As an implementation scheme of the floating support structure, the floating support structure includes a plurality of first support columns 207, which are arranged near the weld gap 203 and supported on the lower side of the first workbench 201 and the second workbench 202; the first support column 207 can be a hydraulic support column, or other controllable height-adjustable structures, such as an electric telescopic rod, a screw rod, etc., but the hydraulic support column has a relatively small axial dimension, low installation requirements, and low use cost, and is more suitable for promotion and application. By controlling the height of the first support column 207, the side of the first workbench 201 and the second workbench 202 near the weld gap 203 can be raised or lowered, thereby adjusting the angle between the working surface of the first workbench 201 and the working surface of the second workbench 202. When in use, according to needs, only the working surface of the first workbench 201 or the working surface of the second workbench 202 can be adjusted, or the working surface of the first workbench 201 and the working surface of the second workbench 202 can be adjusted at the same time.

[0036] In order to cooperate with the first support column 207, the lower sides of the first workbench 201 and the second workbench 202 can also be supported by a rack, a mounting table, etc. Preferably, the floating support structure also includes a plurality of second support columns 208, and the second support columns 208 cooperate with the first support columns 207 to support the first workbench 201 and the second workbench 202. Taking the first workbench 201 as an example, the number of the first support columns 207 is two, which are respectively supported at both ends of the edge of the first workbench 201 close to the weld gap 203 and are hinged to the first workbench 201; the number of the second support columns 208 is also two, which are supported at the edge of the first workbench 201 away from the weld gap 203 and are also hinged to the first workbench 201. Controlling the first support column 207 can adjust the height of the first workbench 201 close to the weld gap 203 side; when the first workbench 201 and the second workbench 202 are adjusted in coordination, the angle between their working surfaces can be adjusted to the design requirements, thereby adapting to different welding operation requirements and achieving the anti-deformation effect of the welding of the first specimen 500 and the second specimen 600.

[0037] The second support column 208 can also be designed as a retractable structure as needed, for example, a hydraulic support column is also used. The first support column 207 and the second support column 208 cooperate to make the adjustment of the working surfaces of the first workbench 201 and the second workbench 202 more flexible to adapt to more welding operation conditions.

[0038] The multifunctional welding platform 200 also has the function of back gas protection during welding. The multifunctional welding platform 200 is provided with a lining plate 222 and a gas channel 211. The lining plate 222 can be extended outward during welding and shielded at the lower side of the weld gap 203, and together with the first workbench 201 and the second workbench 202, a protective gas cavity is formed. The gas channel 211 is located on the upper side of the lining plate 222, and is used to input protective gas, such as argon, into the weld gap 203.

[0039] As a preferred embodiment of the liner 222, Figure 4 and Figure 5As shown, a first chamber 223 is provided in the first workbench 201, and the first chamber 223 is opened on the side of the first workbench 201 facing the weld gap 203; a second chamber 221 is provided in the second workbench 202, and the second chamber 221 is opened on the side of the second workbench 202 facing the weld gap 203. The first chamber 223 and the second chamber 221 are located in corresponding positions, and a lining plate 222 is slidably provided in the first chamber 223 or the second chamber 221, and the lining plate 222 can be located in both the first chamber 223 and the second chamber 221, or in one of the two. For example, the lining plate 222 is arranged in the second chamber 221, and a driving shaft 220 is provided in the second chamber 221; the driving shaft 220 is in transmission connection with the lining plate 222, and the lining plate 222 is pushed and pulled when the driving shaft 220 rotates. Exemplarily, the drive shaft 220 is made of a material with a large friction coefficient such as rubber, and is in direct contact with the lining plate 222, and the friction between the two is used to push and pull the lining plate 222; during the welding operation, the lining plate 222 is controlled to slide until it partially extends into the first chamber 223, so that a shield is formed on the lower side of the weld gap 203.

[0040] The gas channel 211 may be disposed inside at least one of the first workbench 201 and the second workbench 202 , or may be a pipeline external to the first workbench 201 and the second workbench 202 , and the pipeline is directly connected to the weld gap 203 .

[0041] For further information, please refer to Figure 3 The first workbench 201 or the second workbench 202 is further provided with side baffles 206. There are two side baffles 206, which respectively block the two ends of the weld gap 203 in the horizontal direction. As an embodiment of the side baffles 206, the side baffles 206 are slidably arranged on the first workbench 201, and the weld gap 203 can be blocked or opened by pushing and pulling the side baffles 206.

[0042] Preferably, an inwardly concave first slide groove 204 is provided on the two transverse end faces of the first workbench 201, and a second slide groove 205 is provided on the two transverse end faces of the second workbench 202. The first slide groove 204 and the second slide groove 205 at the same end of the weld gap 203 in the transverse direction correspond to each other, and the side baffle 206 is slidably set in the first slide groove 204 and slides into or out of the second slide groove 205.

[0043] The lining plate 222 and the two side baffles 206 respectively form shielding at the lower side and both ends of the weld gap, which can effectively protect the back of the first test piece 500 and the second test piece 600. The distance between the first workbench 201 and the second workbench 202 (i.e., the width of the weld gap 203) is 5-15 mm, providing a suitable working environment for welding.

[0044] The clamping structure 400 is located above the multifunctional welding platform 200; Figure 6 and Figure 7 As shown, the clamping structure 400 includes a mechanical arm 401 and a clamping plate 402. The mechanical arm 401 is fixedly mounted on the multifunctional back plate 300. Of course, the mechanical arm 401 can also be fixedly mounted on the multifunctional welding platform 200 by using a bracket structure as needed. The clamping plate 402 is connected to the mechanical arm 401, so that the clamping plate 402 can be rotated and changed at multiple angles; the mechanical arm 401 adopts an existing product on the market, such as Jiangsu Bronte Technology-BRTIRUS0707A industrial robot; the inventor has not made any improvements to it, so it will not be described in detail here.

[0045] The clamping plate 402 includes a first clamping arm 403 and a second clamping arm 405, which are arranged at intervals and connected as a whole by a connecting arm 404. A welding window 407 is formed between the first clamping arm 403 and the second clamping arm 405. The welding window 407 corresponds to the weld gap 203 during welding, that is, corresponds to the welds of the first test piece 500 and the second test piece 600, and the connecting arm 404 is arranged to avoid the weld position. The mechanical arm 401 is connected to the clamping plate 402 to avoid the welding window 407.

[0046] Preferably, there are two connecting arms 404 , which are respectively located at two ends of the first pressing arm 403 and the second pressing arm 405 .

[0047] A plurality of chess blocks 406 are disposed on the working surfaces of the first clamping arm 403 and the second clamping arm 405 . The chess blocks 406 protrude out of the working surfaces of the first clamping arm 403 and the second clamping arm 405 and directly contact the first test piece 500 and the second test piece 600 when in use.

[0048] Furthermore, the chess block 406 is provided with a heating module, which can heat the first specimen 500 and the second specimen 600 when in contact with the first specimen 500 and the second specimen 600. The heating module can be an electric heating, and of course a heat source channel can be provided in the chess block 406, and the heat source channel can be connected to a device for circulating heat supply, so that the first specimen 500 and the second specimen 600 can be preheated and dehydrogenated without flame heating.

[0049] The working surfaces of the first clamping arm 403 and the second clamping arm 405 are provided with air cooling holes (not shown in the figure), which can reduce the interlayer temperature when welding some materials. The air cooling holes and the chess pieces 406 are staggered to avoid mutual position interference. The air cooling holes are externally connected to a device such as a fan to supply cold air. The setting of the air cooling holes enables the clamping plate 402 to have an air cooling function, which can be applied to welding conditions that require air cooling.

[0050] The multifunctional back panel 300 includes a back panel 301, a connection panel storage mechanism 302, an external tool suspension structure 303, and an intelligent detection display screen 304; wherein the back panel 301 is arranged on one side of the multifunctional welding platform 200, preferably, the back panel 301 is located on the side of the second workbench 202 away from the first workbench 201, and the gas channel 211 is arranged in the first workbench 201, with a reasonable layout, convenient for operation and control. The connection panel storage mechanism 302, the external tool suspension structure 303, and the intelligent detection display screen 304 are all arranged on the side of the back panel 301 facing the multifunctional welding platform 200.

[0051] The intelligent detection display screen 304 has a camera, which can collect, obtain and record the welder's arc light and the position of the welder's movement during welding; the multifunctional welding platform 200 and the clamping plate 402 are both provided with thermal sensors, which can transmit the real-time temperature of the first test piece 500 and the second test piece 600 to the intelligent detection display screen 304 for display and recording. The intelligent detection display screen 304 is an existing product on the market. The intelligent detection display screen 304 is not improved in this application, so its structure and signal transmission process are not described. The temperature of the welding process, the welder's arc light, and the position of the welder's movement during welding are recorded for the evaluation of the welding process, and the welding time can also be obtained according to the change of the welding position.

[0052] The external tool suspension structure 303 includes a number of hooks, plug holes, etc., which can be used to hang some common tools, such as a thermometer, a welding ruler, a square, a tool hammer, etc., and can also be connected to external tools such as a dust cover, a laser rust removal arm, etc.

[0053] The connecting plate storage mechanism 302 can be used to place connecting plates in batches and in a standardized manner for use by welders to start and end arcs. The connecting plate storage mechanism 302 includes a U-shaped plate, which is fixed to the back plate 301, and the two form a storage cavity, in which the connecting plates are stacked. The lower end of the storage cavity is open for taking out the connecting plates.

[0054] like Figure 8 As shown, the enclosure 700 cooperates with the back plate 301 to surround the multifunctional welding platform 200 to play a protective role. Preferably, a dust hood is provided above the multifunctional welding platform 200, and the enclosure 700 can ensure that the dust hood connected to the top has a centralized processing function. Since the dust hood is a common device in the field of welding equipment, it is not shown in the figure, and its structure is not described here. Similarly, the test bench can also be equipped with common welding equipment such as a dust suction device, an automatic laser rust removal device, a welding robot, and a submerged arc welding device.

[0055] During welding operation, The material preparation personnel first hoist the first test piece 500 and the second test piece 600 to the loading device 100; after they are in place, the loading device 100 is started for transmission.

[0056] When the first test piece 500 and the second test piece 600 are transferred to the first longitudinal AGV block 214 and the second longitudinal AGV block 215 on the upstream side of the first workbench 201 and the second workbench 202, the second transverse AGV block 217 and the first transverse AGV block 210 as well as the first longitudinal AGV block 214 and the second longitudinal AGV block 215 on the downstream side of the first workbench 201 and the second workbench 202 are controlled to start. When it is detected that the first test piece 500 and the second test piece 600 stop moving, it means that the feeding device 100 has reached the limit position, and the test piece adjustment mechanism on the first workbench 201 and the second workbench 202 is controlled to perform transverse and longitudinal adjustments. The lateral adjustment is: controlling the first lateral AGV block 210 and the second lateral AGV block 217 to transfer the first test piece 500 and the second test piece 600 to the lateral designated position; The longitudinal adjustment includes: controlling the first longitudinal movement AGV block 214 and the second longitudinal movement AGV block 215 , adjusting the first test piece 500 and the second test piece 600 to set longitudinal designated positions, and adjusting the gap between the first test piece 500 and the second test piece 600 .

[0057] Regardless of whether the lateral adjustment is performed first or the longitudinal adjustment is performed first, in order to ensure that the movement of the first test piece 500 and the second test piece 600 is controllable, during the position adjustment process of the first test piece 500 and the second test piece 600, the electromagnets of the first longitudinal movement AGV block 214, the second longitudinal movement AGV block 215, the first lateral movement AGV block 210, and the second lateral movement AGV block 217 are energized to adsorb the first test piece 500 or the second test piece 600; after the lateral adjustment and the longitudinal adjustment are in place, the electromagnets are turned off to avoid affecting subsequent adjustments.

[0058] If reverse deformation is required, the first support column 207 can be activated to adjust the relative position between the working surfaces of the first workbench 201 and the second workbench 202 to reversely deform the first specimen 500 and the second specimen 600 to the process angle.

[0059] Then, argon gas is delivered into the protective gas chamber; if arc starting and arc ending are required, the connecting plate is taken and placed at the arc starting and arc ending positions; then, the robot arm 401 is started, and the clamping plate 402 is clamped from above the first test piece 500 and the second test piece 600; if preheating is required, the heating module of the chess block 406 is started, and the first test piece 500 and the second test piece 600 are heated to the required temperature, and the intelligent detection display screen 304 displays the real-time temperature; if the required temperature is reached, a voice reminder command is issued and heating is stopped; welding is performed, and while welding, the intelligent detection display screen 304 will record the welding time; after the interlayer temperature rises, the air cooling function of the chess block 406 can be started (limited to materials that allow air cooling), and cold air is delivered to the first test piece 500 and the second test piece 600 through the air cooling hole, effectively reducing the interlayer temperature, and welding is continued. At the same time, the display screen will record the temperature before each welding and the welding time together; until the welding is completed.

[0060] The above process can be controlled by an external operation button or connected to a computer and accurately controlled by conveying instructions, such as argon arc primer 4mm gap, submerged arc welding gap, reverse deformation, conveying, position adjustment, and clamping of the first test piece 500 and the second test piece 600. After preparing the materials, the welder only needs to wait for the first test piece 500 and the second test piece 600 to reach the welding state before welding. During welding, the intelligent detection display screen 304 will automatically judge the time and record the distribution of the weld according to the camera, and finally derive a complete welding record without the intervention of auxiliary personnel.

[0061] Furthermore, adsorption modules are provided on the working surfaces of the first clamping arm 403 and the second clamping arm 405, and the adsorption modules can adsorb the first specimen 500 and / or the second specimen 600 onto the clamping plate 402. The adsorption module can adopt a magnetic structure, such as an electromagnet, or a suction cup, which is externally connected to a negative pressure device.

[0062] When double-sided welding is required, after one-side welding is completed, the first specimen 500 and the second specimen 600 are adsorbed by the robot arm 401, and the robot arm 401 is controlled to first lift the clamping plate 402 perpendicular to the first workbench 201 and the second workbench 202, and then slowly tilt the first specimen 500 and the second specimen 600 to fall, and pull them out after reaching a certain angle, so that the first specimen 500 and the second specimen 600 fall on the first workbench 201 and the second workbench 202, and the specimen adjustment mechanism then moves the first specimen 500 and the second specimen 600 to the appropriate position.

[0063] By using the adsorption module on the clamping plate 402, the test bench can perform vertical welding, horizontal welding, and other welding of the first test piece 500 and the second test piece 600 at different spatial relative positions; at this time, one of the first test piece 500 and the second test piece 600 is adsorbed by the clamping plate 402, and the other is placed and adsorbed on the first workbench 201 or the second workbench 202. As for the weld structure, the test bench can not only weld butt welds, but also fillet welds. By adjusting the clamping plate 402 to be perpendicular to the multifunctional welding platform 200 through the mechanical arm 401, fillet welds can be welded.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
