Description

Technical Field

[0001] This invention relates to the field of protective door welding technology, specifically to a batch welding device for protective door accessories. Background Technology

[0002] During the production of civil defense protective doors, various components such as hinges, reinforcing ribs, and locking pivots need to be welded to the main door leaf. To improve the efficiency and consistency of batch welding, automated equipment such as welding robots or automatic welding guns are now commonly used for welding operations.

[0003] However, in actual production, existing positioning fixtures generally lack effective and flexibly adjustable clamping and positioning methods for accessories with varying shapes and specifications. Accessories are typically placed manually and temporarily fixed with spot welding before welding. This method makes it difficult to guarantee their positional accuracy and perpendicularity, easily leading to cumulative deviations during the final welding stage. Such deviations not only cause welds to deviate from the preset path but may also cause quality problems such as incomplete welds and missed welds, directly affecting the overall structural strength and sealing performance of the protective door. Summary of the Invention

[0004] A batch welding device for protective door accessories includes a workbench and a welding device. The welding device is located on top of the workbench, and a door leaf is mounted on the workbench. Multiple accessories are mounted on the door leaf. A batch welding assembly is also mounted on the workbench. The batch welding assembly is used to stably position and support the multiple accessories to be batch welded on the door leaf. The batch welding assembly includes a base component and multiple adjustment components. The base component is used to provide adjustment and limiting space and limit the door leaf. The adjustment components are used to adjust different limiting positions and angles. The base component includes two support frames, both of which are slidably connected to the top of the workbench. The two support frames are symmetrically distributed on both sides of the door leaf. Each of the two support frames has a cross groove on its top. The adjustment components include a slide rod and two rubber clamps. The slide rod and the cross groove are inserted into each other.

Each electric push rod includes a fixed shaft and a telescopic shaft. The telescopic shaft end of the electric push rod is fixedly connected to the support frame, and the fixed shaft end of the electric push rod is fixedly connected to the top surface of the worktable.

[0006] Furthermore, the adjusting component also includes two abutments, which are symmetrically slidably connected to the bottom of the slide rod. The sides of the two abutments that are far apart from each other are both provided with anti-slip surfaces. The sides of the two abutments that are close to each other are jointly fixedly connected to a spring. A pressure block is slidably connected to the bottom of the slide rod, and a spring is fixedly connected to the top of the pressure block. The top of the spring is fixedly connected to the slide rod, and a push plate is fixedly connected to the top of the pressure block.

[0007] Furthermore, a top frame is fixedly connected to the top of the slide rod, a universal ball is rotatably connected to the top frame, a support rod is slidably connected to the universal ball, and a pressure rod is slidably connected to the top frame. Both ends of the pressure rod pass through the top frame, and the end of the pressure rod near the universal ball is provided with an anti-slip surface. The end of the pressure rod near the universal ball is pressed and engaged with the universal ball. A spring three is sleeved on the pressure rod one, and both ends of the spring three are fixedly connected to the outer wall of the top frame and the end of the pressure rod one that passes through the top frame, respectively. One end of the universal ball extends outward, and a pressure rod two is slidably connected to the end of the universal ball that extends outward. The bottom end of the pressure rod two is provided with an anti-slip surface, and the bottom end of the pressure rod two is pressed and engaged with the support rod. A spring four is sleeved on the pressure rod two, and both ends of the spring four are fixedly connected to the top of the pressure rod two and the universal ball, respectively.

[0008] Furthermore, a support rod is rotatably connected to a carrier plate at the end furthest from the top frame. A pressure rod three is slidably connected to the bottom of the carrier plate. Both ends of the pressure rod three protrude from the carrier plate. The top of the pressure rod three is designed as an anti-slip surface. The top of the pressure rod three is pressed against the support rod. A spring five is fitted on the pressure rod three. Both ends of the spring five are fixedly connected to the bottom surface of the carrier plate and the bottom end of the pressure rod three, respectively. Two telescopic tubes are symmetrically fixedly connected to the bottom end of the carrier plate. The telescopic tubes include a fixed shaft and a telescopic shaft.

With the operation of the adjustment components, the door panels can be limited from all four sides to prevent displacement of the door panels due to external influences during the welding process, ensuring that the door panels are always in the preset welding reference position.

[0014] By adjusting the detachable and multi-directional flexible position adjustment characteristics of the components, as well as the adaptive clamping range, it can be compatible with various accessories, ensuring the universality of the adjustment components. The adjustment components can accurately adjust various accessories to the required welding position, ensuring the positional accuracy and perpendicularity of accessories during batch welding. At the same time, the number and position of clamps can be freely arranged according to the batch welding point requirements of accessories. The mechanical limit and precise adjustment replace the traditional method of manual placement and temporary spot welding, reducing manual operation links, reducing positioning deviations caused by human factors, and avoiding problems such as weld deviation, incomplete welding, and missed welding.

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] Reference Figures 1 to 11 As shown, a batch welding device for protective door accessories includes a workbench 11 and a welding device 12. The welding device 12 is disposed on the top of the workbench 11. A door leaf 13 is disposed on the workbench 11, and multiple accessories 14 are disposed on the door leaf 13.

[0019] The workbench 11 and welding device 12 are existing automated welding mechanisms. The workbench 11 is used to carry and transport the door leaf 13 for movement. The welding device 12 is equipped with a welding actuator. In the prior art, the welding actuator of the welding device 12 can freely move its position and change its angle through the control system to perform welding, thereby enabling the welding device 12 to achieve a wide range and multi-angle welding capability. Both the workbench 11 and the welding device 12 are existing known technologies and will not be described in detail here.

[0020] In the prior art, when welding the accessories 14 to the door leaf 13, various accessories 14 are required, including hinges, reinforcing ribs, locking shaft seats, etc., and different accessories 14 are distributed in different positions of the door leaf 13, such as the top surface, the side surface, etc.

[0021] The workbench 11 is equipped with a batch welding assembly, which is used to securely position and support multiple parts 14 that need to be batch welded on the door leaf 13.

[0022] The batch welding assembly includes a base component and multiple adjustment components.

[0023] The base component is used to provide adjustment limit space and limit the door leaf 13.

[0024] The base assembly includes two support frames 21, both of which are slidably connected to the top of the workbench 11. The two support frames 21 are symmetrically distributed on both sides of the door leaf 13. Two electric push rods 22 are symmetrically arranged on both sides of the door leaf 13. Each electric push rod 22 includes a fixed shaft and a telescopic shaft. The telescopic shaft end of the electric push rod 22 is fixedly connected to the support frame 21, and the fixed shaft end of the electric push rod 22 is fixedly connected to the top surface of the workbench 11. Each of the two support frames 21 has a cross groove 23 on its top.

[0025] Among them, the electric push rod 22 is operated by the control system of the worktable 11.

[0026] The adjustment component is used to adjust different limit positions and angles.

[0027] The adjusting component includes a slide rod 24, which is inserted into a cross groove 23. Two abutments 25 are symmetrically slidably connected to the bottom end of the slide rod 24. The sides of the two abutments 25 that are far apart from each other are both provided with anti-slip surfaces. A spring 1 26 is fixedly connected to the sides of the two abutments 25 that are close to each other. A pressure block 27 is slidably connected to the bottom of the slide rod 24. A spring 28 is fixedly connected to the top of the pressure block 27. The top of the spring 28 is fixedly connected to the slide rod 24. A push plate 29 is fixedly connected to the top of the pressure block 27. The push plate 29 passes through the slide rod 24 and is slidably connected to the slide rod 24.

[0028] A top frame 210 is fixedly connected to the top of the slide rod 24. A universal ball 211 is rotatably connected to the top frame 210. A support rod 212 is slidably connected to the universal ball 211. A pressure rod 213 is slidably connected to the top frame 210. Both ends of the pressure rod 213 pass through the top frame 210. The end of the pressure rod 213 near the universal ball 211 is provided with an anti-slip surface. The end of the pressure rod 213 near the universal ball 211 is pressed against the universal ball 211. A spring 214 is sleeved on the pressure rod 213. The two ends of 14 are fixedly connected to the outer wall of the top frame 210 and the end of the pressure rod 213 that protrudes from the top frame 210, respectively. One end of the universal ball 211 extends outward, and the end of the universal ball 211 that extends outward is slidably connected to the pressure rod 215. The bottom end of the pressure rod 215 is set as an anti-slip surface. The bottom end of the pressure rod 215 is pressed and engaged with the support rod 212. A spring 4 216 is sleeved on the pressure rod 215. The two ends of the spring 4 216 are fixedly connected to the top end of the pressure rod 215 and the universal ball 211, respectively.

[0029] A support rod 212 is rotatably connected to a carrier plate 217 at the end furthest from the top frame 210. A pressure rod 218 is slidably connected to the bottom of the carrier plate 217. Both ends of the pressure rod 218 extend out of the carrier plate 217. The top of the pressure rod 218 is designed as an anti-slip surface. The top of the pressure rod 218 is press-fitted with the support rod 212. A spring 219 is fitted on the pressure rod 218. Both ends of the spring 219 are fixedly connected to the bottom surface of the carrier plate 217 and the bottom end of the pressure rod 218, respectively. Two telescopic tubes 220 are symmetrically fixedly connected to the bottom end of the carrier plate 217. Each telescopic tube 220 includes a fixed shaft and a telescopic... A rubber clamp 221 is fixedly connected to the telescopic shaft end of each of the two telescopic tubes 220. Each of the two telescopic tubes 220 is equipped with a long strip airbag 222 and a spring 6 223. The two ends of the long strip airbag 222 and the spring 6 223 are respectively fixedly connected to the fixed shaft end and the telescopic shaft end of the telescopic tube 220. The spring 6 223 is located inside the long strip airbag 222. An air pump 224 is fixedly connected to the top of the carrier plate 217. The air pump 224 is fixedly connected to the air pipe 1 225 and the air pipe 226 at the air jet end. The air pipe 1 225 is fixedly connected to the two long strip airbags 222.

[0030] Specifically: two triangular plates are symmetrically arranged at the bottom of the pressure block 27, located on both sides of the spring 26, so that the up-and-down movement of the pressure block 27 does not interfere with the spring 26. The top of the two abutments 25 on the side closest to each other is set as an inclined surface, and the two abutments 25 are pressed and engaged with the pressure block 27.

[0031] The function of the push plate 29 is to facilitate the user to move the pressure block 27.

[0032] Where: Reference Figure 8 , Figure 9 As shown, the top frame 210 and the universal ball joint 211, as well as the support rod 212 and the carrier plate 217, all form ball joints in the prior art. The universal ball joint 211 can rotate freely within the top frame 210, and the support rod 212 can rotate freely within the carrier plate 217. This enables multi-angle rotational movement, giving the carrier plate 217 rotational flexibility in multiple directions. Combined with the free sliding of the support rod 212 within the universal ball joint 211, the carrier plate 217 can not only rotate flexibly but also move, allowing it to be moved more precisely to the position on the door leaf 13 where the welding accessory 14 needs to be placed.

[0033] It should be noted that when pressure lever 213 contacts and compresses the universal ball 211, the universal ball 211 is restricted. When pressure lever 218 contacts and compresses the support rod 212, the support rod 212 is restricted. When pressure lever 215 contacts and compresses the support rod 212, the support rod 212 is restricted.

[0034] Among them, the two rubber clamps 221 are both set as anti-slip surfaces on the side that is close to each other. Their function is to provide friction for the accessory 14, and to conform to the complex shape of the accessory 14 through the deformation ability of the rubber material. In addition, the softness of the rubber material can prevent the accessory 14 from being damaged during the clamping process.

[0035] Specifically, the second air tube 226 is flexible, meaning that the first spring 26 can maintain its bent shape after being bent and deformed. The end of the second air tube 226 away from the air pump 224 is set as an opening.

[0036] In the initial state of the batch welding assembly, that is, before the welding operation of accessory 14 and door leaf 13 is performed, the state of each structure in the batch welding assembly is as follows: The telescopic shafts of the two electric push rods 22 are not extended. Multiple adjustment components are not mounted on the support frame 21. The slide rod 24 is not engaged with the cross slide groove 23. Spring 28 does not undergo elastic deformation. The pressure block 27 presses against the two abutments 25, with the ends of the two abutments 25 extending outwards from the bottom of the slide rod 24. Spring 1 26 is elastically stretched. Springs 3 214, 4 216, and 5 219 do not undergo elastic deformation. Pressure rod 1 213 presses against the universal ball 211, which is confined within the top frame 210. Pressure rod 215 presses against the support rod 212, which is confined within the universal ball 211. Pressure rod 3 218 presses against the support rod 212, and the carrier plate 217 is confined on the support rod 212. The two long airbags 222 were not inflated, the two springs 223 did not undergo elastic deformation, the telescopic shafts of the two telescopic tubes 220 were retracted within the fixed shaft, and the distance between the two rubber clamps 221 was at its maximum. The air pump 224 was not started.

[0037] During the batch welding of components, that is, when multiple parts 14 need to be welded onto the door leaf 13 in batches, the batch welding process proceeds as follows: The workbench 11 moves the door leaf 13 to the welding position of the welding device 12. The user drives the two electric push rods 22 to extend their telescopic shafts, thereby pushing the two support frames 21 to slide together on the workbench 11. This causes the two support frames 21 to fit against the two sides of the door leaf 13, thus clamping and limiting the door leaf 13 and preventing it from being moved by external forces during the welding process, which could have a negative impact.

[0038] The user then needs to configure the batch welding components as follows: The user specifies the number of parts 14 to be batch welded, and the welding positions of the multiple parts 14 on the door leaf 13, and performs different adjustments according to different welding positions. The user selects an adjustment component equal to the number to be welded. At this time, the user places the parts 14 between the two rubber clamps 221. Then, the user starts the air pump 224, causing the air pump 224 to spray gas into the first air pipe 225 and the second air pipe 226. The gas flows through the first air pipe 225 into the two elongated air bags 222, causing the two elongated air bags 222 to gradually inflate within the corresponding telescopic tubes 220. As the two elongated air bags 222 inflate, they push the telescopic shafts of the corresponding telescopic tubes 220 to extend, thereby bringing the two rubber clamps 221 closer together. During this process, the two rubber clamps 221 gradually contact and squeeze the parts 14, clamping and limiting the parts 14. Simultaneously, the gas ejected from the air pump 224 flows into the air tube 226, and the gas is ejected outward from the bottom end of the air tube 226. At this time, the user bends the air tube 226 so that the bottom jet end of the air tube 226 faces the welding position of the accessory 14. Due to the flexibility of the air tube 226, it can maintain its deformed shape after being bent. Thus, the bottom jet end of the air tube 226 always faces the welding position of the accessory 14.

[0039] It should be noted that when the two rubber clamps 221 hold the accessory 14, the rubber clamps 221 abut against the accessory 14 in a position that does not affect the welding, thereby facilitating the welding device 12 to perform welding operations on the accessory 14.

[0040] It should be noted that as gas fills the long strip airbag 222, since the long strip airbag 222 can only expand and extend inside the telescopic tube 220, the upper limit of the expansion of the long strip airbag 222 is the upper limit of the extension of the telescopic tube 220. When the telescopic tube 220 is fully extended, or when the rubber clamp 221 clamps the accessory 14 so that the telescopic tube 220 can no longer extend, the long strip airbag 222 expands to its limit inside the telescopic tube 220. The air tube 225 can no longer inject gas into the long strip airbag 222 to make the telescopic tube 220 expand. At this time, the two long strip airbags 222 and the air tube 225 can be regarded as being in a state of full internal gas. The airflow ejected by the air pump 224 cannot continue to flow into the already full air tube 225. Instead, the airflow from the air pump 224 will no longer flow into the air tube 225, but will instead flow entirely into the air tube 226. This allows additional airflow to enter the air tube 226, increasing the airflow speed within it. Furthermore, since the air tube 225 and the two elongated air bladders 222 are already full, the two elongated air bladders 222 can remain fully inflated as the air pump 224 ejects air. This means the two telescopic tubes 220 remain extended, fixing the clamping state of the accessory 14 on the two rubber clamps 221, thus fixing the accessory 14 in a limited position.

[0041] After clamping multiple parts 14 to be welded in sequence, the user installs the adjustment components on the support frame 21, as follows: When the user pushes the push plate 29 upward, the pressure block 27 moves upward inside the slide bar 24. At this time, the second spring 28 is elastically compressed, and the pressure block 27 no longer squeezes the two abutments 25. Under the elastic contraction of the first spring 26, the first spring 26 pulls the two abutments 25 inward at the bottom of the slide bar 24, so that the two abutments 25 are retracted into the slide bar 24. After completion, the user inserts the slide rod 24 into the cross groove 23. Then, the user slides the slide rod 24 in the cross groove 23. The slide rod 24 drives the clamped accessory 14 to move on the support frame 21. When the accessory 14 moves on the support frame 21 to the position corresponding to the welding position on the door leaf 13, the user stops sliding the slide rod 24 and stops pushing the push plate 29. Then, under the elastic extension of the second spring 28, the pressure block 27 is pushed downward. The two triangular plates at the bottom of the pressure block 27 abut against and squeeze the two abutment blocks 25, pushing the two abutment blocks 25 outward at the bottom of the slide rod 24. At the same time, the first spring 26 is elastically stretched, so that the two abutment blocks 25 extend outward at the bottom of the slide rod 24 to abut against and squeeze the groove wall of the cross groove 23. At this time, the part of the slide rod 24 inserted into the cross groove 23 and the two abutment blocks 25 form a cross shape. This cross shape fits the cross groove 23 and can prevent the slide rod 24 from tilting under external force in the cross groove 23. At the same time, the anti-slip surfaces of the two abutments 25 are pressed against the groove wall of the cross slide groove 23, providing friction for the slide rod 24, thereby fixing the position of the slide rod 24 in the cross slide groove 23, which can initially fix the position of the positioned accessory 14.

[0042] After completion, the user can pull the pressure rods 213, 215, and 218 respectively to elastically stretch the springs 214, 216, and 219, releasing the omnidirectional ball 211, support rod 212, and carrier plate 217. The user can then move the accessory 14 flexibly in multiple directions and angles while keeping it clamped on the carrier plate 217. Specifically, the accessory 14 is moved to the welding position on the door leaf 13, ensuring it is in contact with the door leaf 13. After completion, the user stops pulling the pressure rods 213, 215, and 218. With the elastic reset of the springs 214, 216, and 219, pressure rod 213 compresses and limits the omnidirectional ball 211, pressure rod 215 compresses and limits the support rod 212, and pressure rod 218 compresses and limits the carrier plate 217. At this time, the slide bar 24 is limited on the support frame 21, thereby limiting the movement of each part of the adjustment component and firmly fixing the accessory 14 to the door leaf 13, providing a stable foundation for the welding work of the accessory 14.

[0043] After securing a single component 14, the user positions the remaining components 14, so that multiple components 14 are positioned at different locations on the door leaf 13, such as the top or side, according to the required welding locations.

[0044] Meanwhile, the user can use the adjustment component without clamping accessory 14 to move the adjustment component to the side of the door leaf 13, so that the rubber clamp 221 of the adjustment component is pressed against the side of the door leaf 13, so that the four sides of the door leaf 13 are locked by the two support brackets 21 and the rubber clamp 221 of the adjustment component, forming a four-sided limit on the door leaf 13, thereby achieving stable limit on the door leaf 13.

[0045] Once all the components 14 are positioned on the door leaf 13 to be welded, the welding device 12 begins welding the door leaf 13. Through the welding actuator on the welding device 12, multiple components 14 are welded onto the door leaf 13 in a single batch. During the welding process, the gas pipe 226 continuously sprays gas onto the welding area between the components 14 and the door leaf 13 to achieve precise cooling and to blow away splattered molten slag and welding dust, preventing weld defects caused by slag residue.

[0046] After the welding work is completed, the user drives all the air pumps 224, so that the air pumps 224 stop venting and start venting, thereby venting the gas in the long air bag 222. Under the elastic contraction of the spring six 223, the long air bag 222 vents and contracts, which drives the telescopic shaft of the telescopic tube 220 to contract, thereby causing the two rubber clamps 221 to move away from each other. At this time, the two rubber clamps 221 no longer resist the accessory 14, and as the gas in the long air bag 222 is completely vented, the two rubber clamps 221 are driven to detach from the accessory 14.

[0047] After completion, the user drives the two electric push rods 22 to operate. The telescopic shafts of the two electric push rods 22 retract, thereby causing the two support frames 21 to move away from each other. The two support frames 21 drive all the adjustment components on them to move synchronously, so that the adjustment components are completely separated from the door leaf 13.

[0048] It should be noted that since the rubber clamp 221 has already detached from the accessory 14, the movement of the adjustment component will not interfere with the accessory 14. As the two support frames 21 move away from each other to their reset positions, the four sides of the door leaf 13 are no longer restricted, and the worktable 11 can move the door leaf 13 to the next processing station.

[0049] It should be noted that after completing a single welding operation of the door leaf 13, if subsequent welding operations of the same number and positions of accessories 14 are performed, the already configured adjustment components can be reused multiple times without needing to readjust the number and position of the adjustment components. The user can fix multiple accessories 14 to the adjustment components while the support frame 21 is not in contact with the door leaf 13. When welding the door leaf 13 again, as the two support frames 21 move closer to each other, the support frames 21 drive multiple accessories 14 to move synchronously, causing the accessories 14 to contact the door leaf 13 and slide horizontally. When the support frame 21 contacts the side of the door leaf 13, the multiple accessories 14 move to the position to be welded.

[0050] This allows for the reuse of the previous configuration of the adjusted components when dealing with the same batch of welding operations. Multiple components 14 to be welded can be horizontally moved from both sides of the door leaf 13 to their welding positions on the door leaf 13. Simultaneously, the four sides of the door leaf 13 are limited by the support frame 21 and the rubber clamps 221 specifically designed to limit the movement of the door leaf 13. This achieves versatility for batch welding of components.

[0051] In summary, the following beneficial effects can be achieved by operating batch welding of components: By setting two support frames 21 that can move equidistantly along the central axis of the workbench 11, the spacing can be adjusted according to different specifications of door panels 13. With the operation of the adjustment components, the door panels 13 can be limited from all four sides to avoid displacement of the door panels 13 due to external influences during the welding process, and to ensure that the door panels 13 are always in the preset welding reference position.

[0052] By adjusting the detachable and flexible multi-directional positioning characteristics of the components, as well as the adaptive clamping range, it can be compatible with various accessories 14, ensuring the universality of the adjustment components. The adjustment components can accurately adjust various accessories 14 to the required welding position, ensuring the positional accuracy and perpendicularity of accessories 14 during batch welding. At the same time, the number and position of clamps can be freely arranged according to the batch welding point requirements of accessories 14. The mechanical limit and precise adjustment replace the traditional method of manual placement and temporary spot welding, reducing manual operation links, reducing positioning deviations caused by human factors, and avoiding problems such as weld deviation, incomplete welding, and missed welding.
