Description

Technical Field

[0001] This utility model relates to the field of argon arc welding technology, and in particular to welding fixtures for stabilizers. Background Technology

[0002] A flame stabilizer is a device used to maintain flame stability in combustion equipment. It is an essential component in combustion equipment that requires stable combustion. During the casting process of a flame stabilizer, some cracks and porosity may occur. After these defects are removed, the different components of the flame stabilizer need to be welded together with the aid of argon arc welding, which requires argon gas as a shielding gas.

[0003] Due to the unique structure of the flame stabilizer, the metal on the back of the flame stabilizer may oxidize during argon arc welding, and the argon gas will also dissipate rapidly during the welding process, resulting in high welding costs. Therefore, a special tooling fixture is needed to reduce welding costs while ensuring welding quality. Utility Model Content

[0004] The purpose of this invention is to provide a stabilizer welding fixture to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] The stabilizer welding fixture includes a base plate, a perimeter of which is surrounded, and an upper cover plate is detachably mounted on the top of the perimeter.

[0007] The base plate, enclosure, and top cover form an airtight cavity;

[0008] The volume of the cavity is between 3 and 20 times the volume of the stabilizer component to be welded;

[0009] The base plate has a carrier for placing the stabilizer components to be welded;

[0010] The enclosure is provided with at least one interface as a protective gas inflation port;

[0011] The fence has at least two positioning holes on its upper part and at least two positioning posts on its lower part.

[0012] The upper cover plate is provided with at least one placement opening for placing stabilizer components.

[0013] In a further embodiment, the inner wall of the enclosure is provided with a plurality of sliding grooves;

[0014] Each of the multiple sluices can be detachably installed with a partition, and each partition, together with the base plate, the enclosure, and the top cover plate, forms an airtight isolation cavity. Each isolation cavity does not contain a protective gas inflation port.

[0015] By adopting the above technical solution, the flame stabilizer is first placed inside the fixture consisting of the base plate and the enclosure. Then, multiple corresponding partitions are inserted according to the shape of the flame stabilizer. The partitions are detachably installed on the inner side wall of the enclosure via sliding grooves, thus effectively improving the versatility of the fixture and avoiding multiple design wastes of resources. After the top cover is closed, the part to be welded is placed from the placement port into the corresponding position of the flame stabilizer. The protective gas argon is filled from the protective gas filling port into the airtight cavity formed by the base plate, enclosure, and top cover. The partitions can also form new isolation cavities with the base plate, enclosure, and top cover. These isolation cavities significantly reduce the amount of argon required to fill the fixture. The welding torch performs argon arc welding through the placement port. The partitions effectively reduce the amount of argon that needs to be filled, while the top cover effectively reduces the escape of argon. The combination of these two measures reduces welding costs while ensuring welding quality.

[0016] In a further embodiment, the base plate is provided with at least one clamping mechanism for clamping the stabilizer component to be welded;

[0017] The enclosure is equipped with protective gas inflation ports at the lower center of both adjacent sides below the placement opening.

[0018] The two protective gas filling ports are connected to the same protective gas source through a T-junction.

[0019] In a further embodiment, an openable cover is provided at the placement port, and the cover has an opening smaller than the placement port, serving as a welding operation port.

[0020] By adopting the above technical solution, if the position of the component and the flame stabilizer changes during the welding process, it will greatly affect the welding quality. The flame stabilizer itself is fixed by the partition, so a clamping mechanism is needed to stabilize the component. The advantage of setting multiple protective gas inlets is that it can more evenly protect the flame stabilizer during the welding process. The gas inlet set at the middle and lower height can ensure that the argon gas escape rate is slower. Moreover, the openable cover plate can facilitate the placement of the component, and during the welding process, the smaller welding operation port on the cover plate can further slow down the argon gas escape rate on the original basis.

[0021] In a further embodiment, a slide rail is provided above the upper cover plate, a cover plate is slidably mounted on the slide rail, and at least one spare placement opening is also provided on the upper cover plate.

[0022] By adopting the above technical solution, there are two slide rails arranged in parallel. The placement port and the spare placement port are both located in the middle of the two slide rails. The width of the placement port and the spare placement port is also smaller than that of the cover plate. Therefore, the cover plate can block the placement port, or the spare placement port can be blocked by sliding to the other end of the slide rail. The reason for setting the spare placement port is that there is another component on the other side of the flame stabilizer that needs to be welded on by argon arc welding. Setting two placement ports on a top cover plate not only saves materials, but also makes replacement and storage more convenient.

[0023] In a further embodiment, a circular pull ring is vertically disposed above the cover.

[0024] By adopting the above technical solution, after the components on one side of the flame stabilizer are welded, it is necessary to flip it over and weld another component. Since the temperature of argon arc welding is very high, the temperature conducted to the tooling is also very high. Therefore, it is not possible to directly contact the cover plate or the top cover plate. The top cover plate can be lifted by a hoist and the flame stabilizer can be flipped over by using a circular pull ring. At the same time, the cover plate can be pulled by a hoist or other tools to cover the through groove of a specific shape.

[0025] In a further embodiment, at least one gas collecting hood is provided above the baffle, with the large end of the gas collecting hood facing the placement opening and the small end of the gas collecting hood facing the circular pull ring.

[0026] By adopting the above technical solution, the gas collecting hood is shaped like a quarter sphere, with its open large end facing the placement port. This makes it easier for operators to perform argon arc welding on the flame stabilizer. The bottom of the gas collecting hood and the top of the shield are fixedly connected. The gas collecting hood can collect argon gas when it escapes into the air, and can also prevent some external impurities such as dust from entering the tooling during the welding process and affecting the welding quality.

[0027] In a further embodiment, the gas collection hood is provided with a suction pipe, one end of which is connected to a vacuum pump, and the other end of which is connected to the small end of the gas collection hood.

[0028] It also includes a gas storage bladder, and the outlet of the vacuum pump is connected to the gas storage bladder.

[0029] By adopting the above technical solution, when an existing gas recovery system is available, argon gas recovery is an economical option. The vacuum pump is set to a small suction force to collect a portion of the argon gas escaping from the placement port and spare placement port of the upper cover plate without affecting the argon arc welding. This argon gas will mix with air and be collected into the gas storage bag for recovery. At the same time, when other welding processes are used, if gases that are harmful to the human body but have minor hazards are generated during the welding process, they can also be collected through the gas collection hood and vacuum pump, thereby improving safety.

[0030] In a further embodiment, a clamping device is also included, which includes an upper clamping plate, a lower clamping plate, and a locking bolt. The upper clamping plate is disposed above the upper cover plate, and the lower clamping plate is disposed below the bottom plate. The upper clamping plate and the lower clamping plate are connected by the locking bolt.

[0031] By adopting the above technical solution, the upper and lower clamping plates are controlled to tighten and loosen by locking bolts. The main function of this device is to ensure that the cavity formed by the upper cover plate, the enclosure and the bottom plate during the welding process is more airtight and to avoid argon gas from leaking out of the gaps as much as possible.

[0032] In summary, this utility model has the following beneficial effects:

[0033] 1. By setting up the top cover plate and partitions, the flame stabilizer set on the base plate can be isolated by multiple partitions of corresponding shapes. The detachable partitions can accommodate various models of flame stabilizers. When the top cover plate is closed, the part to be welded is placed from the placement port into the corresponding position of the flame stabilizer. The protective gas argon is filled from the protective gas filling port into the airtight cavity formed by the base plate, the enclosure, and the top cover plate. The partitions can also form new isolation cavities with the base plate, the enclosure, and the top cover plate. These isolation cavities significantly reduce the amount of argon required to fill the tooling. The welding torch performs argon arc welding through the placement port. The partitions effectively reduce the amount of argon that needs to be filled, while the top cover plate effectively reduces the escape of argon. The combination of the two reduces welding costs while ensuring welding quality.

[0034] 2. By setting up a baffle, the baffle, which is wider than both the placement opening and the spare placement opening, can be used to block either the placement opening or the spare placement opening after sliding. The reason for setting up the spare placement opening is that there is another component on the other side of the flame stabilizer that needs to be welded by argon arc welding. Setting up two placement openings on a top cover not only saves materials but also facilitates replacement and storage. The shape of the gas collection hood on the baffle is a quarter-sphere, and there are two in total. When the baffle is located at the middle point of the slide rail, the larger open end of the gas collection hood at one end of the baffle faces the placement opening, and the larger open end of the gas collection hood at the other end of the baffle faces the spare placement opening. This makes it easier for operators to perform argon arc welding on the flame stabilizer. The bottom of the gas collection hood is fixedly connected to the top of the baffle. The gas collection hood can collect the argon gas when it escapes into the air and also prevent some external impurities such as dust from entering during the welding process, which achieves the effects of environmental protection and ensuring welding quality.

[0035] 3. The locking device allows the upper and lower clamping plates to be tightened and loosened by locking bolts. The main function of this device is to ensure better airtightness of the cavity formed by the upper cover plate, enclosure and base plate during the welding process, thereby minimizing the loss of argon gas from the gaps.

[0042] like Figure 1 - Figure 3 As shown, the stabilizer welding fixture includes a base plate 1, a perimeter of which is provided with a guardrail 2, and an upper cover plate 3 is detachably mounted on the top of the guardrail 2.

[0043] The base plate 1, the enclosure 2, and the top cover plate 3 form an airtight cavity;

[0044] The volume of the cavity is between 3 and 20 times the volume of the stabilizer component to be welded;

[0045] The base plate 1 has a carrier for placing the stabilizer components to be welded;

[0046] At least one interface is provided on the enclosure 2 as a protective gas inflation port;

[0047] At least two positioning holes are provided on the top of the enclosure 2, and at least two positioning posts are provided on the bottom of the top cover plate 3;

[0048] The upper cover plate 3 is provided with at least one placement opening for placing stabilizer components.

[0049] Furthermore, multiple grooves are provided on the inner wall of the enclosure 2;

[0050] Multiple sluices can be detachably installed with partitions 4. Each partition 4, together with the base plate 1, the enclosure 2, and the top cover plate 3, forms an airtight isolation chamber. Each isolation chamber does not contain a protective gas inflation port.

[0051] In this embodiment, the flame stabilizer is first placed inside the fixture consisting of the base plate 1 and the enclosure 2. Then, multiple corresponding partitions 4 are inserted according to the shape of the flame stabilizer. The partitions 4 are detachably installed on the inner side wall of the enclosure 2 via sliding grooves, thus effectively improving the versatility of the fixture and avoiding multiple design wastes of resources. After the top cover plate 3 is covered, the component to be welded is placed from the placement port into the corresponding position of the flame stabilizer. The protective gas argon is filled from the protective gas filling port into the airtight cavity formed by the base plate 1, the enclosure 2, and the top cover plate 3. The partitions 4 can also form new isolation cavities with the base plate 1, the enclosure 2, and the top cover plate 3. These isolation cavities significantly reduce the amount of argon required to fill the fixture. The welding torch performs argon arc welding through the placement port. The partitions 4 effectively reduce the amount of argon that needs to be filled, while the top cover plate 3 effectively reduces the escape of argon. The combination of the two reduces the welding cost while ensuring the welding quality.

[0052] Furthermore, the base plate 1 is provided with at least one clamping mechanism for clamping the stabilizer component to be welded;

[0053] Below the placement opening, on both sides of the enclosure 2, there are protective gas inflation ports in the lower middle position;

[0054] The two protective gas filling ports are connected to the same protective gas source through a T-junction.

[0055] Furthermore, an openable cover is provided at the placement port, and the cover has an opening smaller than the placement port, serving as a welding operation port.

[0056] In this embodiment, if the position of the component and the flame stabilizer changes during the welding process, it will greatly affect the welding quality. The flame stabilizer itself is fixed by the partition 4, so a clamping mechanism is needed to stabilize the component. The advantage of setting multiple protective gas inlets is that they can more evenly protect the flame stabilizer during the welding process. The gas inlet set at the middle and lower height can ensure that the argon gas escapes more slowly. The openable cover can facilitate the placement of the component, and during the welding process, the smaller welding operation port on the cover can further slow down the escape rate of argon gas.

[0057] Furthermore, a slide rail is provided above the upper cover plate 3, and a cover plate is slidably installed on the slide rail. At least one spare placement opening is also provided on the upper cover plate 3.

[0058] In this embodiment, there are two slide rails arranged in parallel. The placement port and the spare placement port are both located in the middle of the two slide rails. The width of the placement port and the spare placement port is also smaller than that of the cover plate. Therefore, the cover plate can block the placement port, or the spare placement port can be blocked by sliding to the other end of the slide rail. The reason for setting the spare placement port is that there is another component on the other side of the flame stabilizer that needs to be welded on by argon arc welding. Setting two placement ports on a top cover plate 3 not only saves materials, but also makes replacement and storage more convenient.

[0059] Furthermore, a circular pull ring 5 is vertically installed above the cover.

[0060] In this embodiment, after the components on one side of the flame stabilizer are welded, it is necessary to flip it over and weld another component. Since the temperature of argon arc welding is very high, the temperature conducted to the tooling is also very high. Therefore, it is not possible to directly contact the shield or the top cover plate 3. The top cover plate 3 can be lifted by a hoist and the flame stabilizer can be flipped over by using the circular pull ring 5. At the same time, the shield can be pulled by a hoist or other tools to cover the through groove of a specific shape.

[0061] Furthermore, at least one gas collection hood 6 is provided above the baffle, with the large end of the gas collection hood 6 facing the placement opening and the small end of the gas collection hood 6 facing the circular pull ring 5.

[0062] In this embodiment, the gas collecting hood 6 is shaped like a quarter sphere, with its open large end facing the placement port. This makes it easier for operators to perform argon arc welding on the flame stabilizer. The bottom of the gas collecting hood 6 is fixedly connected to the top of the shield. The gas collecting hood 6 can collect argon gas when it escapes into the air, and can also prevent some external impurities such as dust from entering the tooling during the welding process and affecting the welding quality.

[0063] Furthermore, a suction pipe 7 is provided on the gas collection hood 6. One end of the suction pipe 7 is connected to a vacuum pump, and the other end of the suction pipe 7 is connected to the small end of the gas collection hood 6.

[0064] It also includes a gas storage bladder, and the outlet of the vacuum pump is connected to the gas storage bladder.

[0065] In this embodiment, when an existing gas recovery system is available, recovering argon is an economical option. The vacuum pump is set to a small suction force to collect a portion of the argon that escapes from the placement port and the spare placement port of the upper cover plate 3 without affecting the argon arc welding. This argon will mix with air and be collected into the gas storage bag for recovery. At the same time, when other welding processes are used, gases that may be harmful to the human body but have minor hazards may also be generated during the welding process. These gases can also be collected by the gas collection hood 6 and the vacuum pump, thereby improving safety.

[0066] Furthermore, it also includes a clamping device 8, which includes an upper clamping plate 81, a lower clamping plate 82 and a locking bolt 83. The upper clamping plate 81 is located above the upper cover plate 3, and the lower clamping plate 82 is located below the base plate 1. The upper clamping plate 81 and the lower clamping plate 82 are connected by the locking bolt 83.

[0067] In this embodiment, the upper clamping plate 81 and the lower clamping plate 82 are controlled to tighten and loosen by locking bolts 83. The main function of this device is to ensure that the cavity formed by the upper cover plate 3, the enclosure 2 and the bottom plate 1 has better airtightness during the welding process, and to avoid argon gas from leaking out of the gaps as much as possible.
