[0022] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0023] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0025] like Figure 1-4 As shown, this embodiment provides a small outfitting fixing device, including: a fixing component 1, a plurality of extension components 2, a main adsorption component 3, a plurality of locking components 4 and a plurality of supporting components 5, the fixing component 1 includes a first fixed workpiece 101 and a second fixed workpiece 102 vertically cross-connected, the centers of the first fixed workpiece 101 and the second fixed workpiece 102 overlap and are provided with a through hole, the main adsorption component 3 is movably installed on the fixing component 1, and the bottom end of the main adsorption component 3 passes through the through hole so that the bottom end of the main adsorption component 3 is located below the fixing component 1, the bottom end of the main adsorption component 3 is used to adsorb small outfitting components, each of the extension components 2 is respectively connected to the end of the first fixed workpiece 101 and the second fixed workpiece 102, and is locked by the locking component 4, and each of the supporting components 5 is movably installed at the end of each of the extension components 2, and can move up and down relative to the extension component 2 to adjust the bottom end height of the main adsorption component 3.

[0026] Based on the above scheme, the center positions of the first fixed workpiece 101 and the second fixed workpiece 102 included in the fixing component 1 overlap and are vertically connected, and corresponding through holes are opened at the center positions of the two. The bottom end of the main adsorption component 3 can pass through the through hole and extend downward. Here, the main adsorption component 3 can be locked at any position, that is, the height of the main adsorption component 3 can be adjusted according to actual welding requirements, thereby adjusting the welding height of small outfitting parts. During the welding process, considering that a certain dimension of the small outfitting parts is large, such as a long length, the original fixing component 1 cannot effectively and stably adsorb the small outfitting parts. In this case, the fixing component 1 is extended, specifically, an extension piece 2 is added to the end of the first fixed workpiece 101 and the second fixed workpiece 102, and the extension piece 2 is locked by the locking piece 4 to ensure that the fixing component 1 and the extension piece 2 remain horizontal after connection. After the extension piece 2 is added, a support piece 5 is inserted at the end of the extension piece 2. The support piece 5 can move relatively up and down. The purpose of the up and down movement is to adjust the height of the extension piece 2, and then adjust the height of the adsorbed small outfitting parts to facilitate welding. This solution provides a fixed support for the welding process of small outfitting parts. When faced with a complex shipbuilding environment, the use of this fixing device can meet the requirements of small outfitting parts for welding conditions, and the welding height can be adjusted quickly at any time. Moreover, since most of the overall structure of the device is detachable, it can be adaptively disassembled and assembled according to the complexity of the installation environment to ensure that the device can be stably fixed in the installation environment, thereby ensuring that small outfitting parts can be effectively and stably adsorbed, providing a prerequisite guarantee for the accuracy of welding work.

[0027] In addition, in the above scheme, the support member 5 is mainly a strip-shaped structure, located at the four end corners of the entire fixing device, and can directly abut the ground to support the entire device. When facing uneven ground, the support member 5 can be clamped in the gap for support due to its compact structure. It can be understood that the support member 5 is inserted between the two devices to achieve the purpose of stabilizing the support device. From another perspective, due to the strip-shaped design of the support member 5, it can better adapt to complex installation environments and play a role in stabilizing small outfitting parts. In addition, the various support members 5 are independent of each other, so when facing an installation environment with inconsistent heights, the height of each support member 5 can be independently adjusted to achieve the overall leveling of the first fixed workpiece 101 and the second fixed workpiece 102, greatly improving the scope of application of the fixing device.

[0028] Optionally, the main adsorption component 3 includes a pull ring 301, a main adsorption rod 302, and a magnetic base 303. The pull ring 301 is installed at the top end of the main adsorption rod 302, and the magnetic base 303 is installed at the bottom end of the main adsorption rod 302. The main adsorption rod 302 is inserted into the through hole and can move up and down relative to the fixed component 1. Providing a pull ring 301 structure at the top end of the main adsorption rod 302 can facilitate the adjustment operation of the entire main adsorption component 3. By inserting the hand into the pull ring 301, the main adsorption rod 302 and the magnetic base 303 can be driven to move up and down. The magnetic base 303 can effectively adsorb small outfitting parts. The main adsorption rod 302 limits the up and down movement stroke of small outfitting parts. At the same time, in order to prevent the movement stroke from exceeding the preset range, the pull ring 301 and the magnetic base 303 can serve as upper and lower limiters of the main adsorption rod 302, effectively preventing the small outfitting parts from being displaced too much and detached.

[0029] To facilitate assembly between the main adsorption component 3 and the fixed component 1, a detachable structure is designed between the main adsorption rod 302 and the magnetic base 303. When the main adsorption component 3 needs to be assembled to the fixed component 1, the magnetic base 303 is first removed, the main adsorption rod 302 is passed through the through hole and extended, and then the magnetic base 303 is assembled to the bottom end of the main adsorption rod 302. The detachable structure here can be a snap-on connection or locked with fasteners such as screws or bolts. Different detachable designs can be selected according to actual conditions.

[0030] Preferably, the main adsorption component 3 also includes a trigger switch and a circuit component. The circuit component is installed inside the main adsorption rod 302 and is connected to the magnetic base 303. When the circuit component is turned on, the magnetic base 303 generates a magnetic attraction force that can be used to adsorb small outfitting parts. The trigger switch is provided on the upper part of the main adsorption rod 302 and is electrically connected to the circuit component to control the on or off of the circuit component. The provision of a trigger switch and a circuit component can improve the convenience and flexibility of adsorbing small outfitting parts. The magnetic attraction of the magnetic base 303 can be controlled by the passage and disconnection of the circuit component. When the circuit component is turned on, the magnetic base 303 generates a magnetic force that can adsorb small outfitting parts. Adsorption here means that when the circuit component is turned on, the magnetic attraction force generated by the magnetic base 303 can effectively and stably adsorb small outfitting parts without detachment or deviation, thereby ensuring that small outfitting parts can be precisely welded at the predetermined welding position. After the welding of the small outfitting parts is completed, it is necessary to put down the small outfitting parts. You only need to control the circuit component to disconnect it, and the magnetic force of the magnetic base 303 will disappear, and the small outfitting parts can be removed. This method of adsorption and putting down avoids the situation of manually pulling out the small outfitting parts, because sometimes when faced with a large adsorption force, the operator needs to use a lot of force to remove the small outfitting parts, which is a negative effect on work efficiency and manpower. Using circuit components to control the generation of magnetic attraction can effectively solve the above problems, effectively save manpower and material resources, and improve work efficiency. This method can also be to power on the circuit component for adsorption after the small outfitting parts and the magnetic base 303 are completely aligned, ensuring that the magnetic base 303 accurately adsorbs the small outfitting parts in the correct position. In addition, setting a touch switch to control the state of the circuit component is for convenient control.

[0031] To ensure safety during use, the outer surface of the main suction rod 302 is coated with an insulating layer. The circuit components are located within the main suction rod 302, and there is still a risk of leakage when powered. To prevent unexpected safety incidents, an insulating layer is wrapped around the outer surface of the main suction rod 302 to isolate the current and prevent the risk of electric shock. Furthermore, an insulating layer can also be wrapped around the sides of the magnetic base 303, as long as the magnetic base 303 and the small outfitting parts are not affected.

[0032] In some embodiments, the through-hole is a threaded hole, and the outer wall of the main suction rod 302 is provided with a threaded structure that rotatably engages the threaded hole. The main suction rod 302 is height-adjustable via a threaded connection, resulting in a simple and effective structure. The pull ring 301 drives the main suction rod 302 to rotate, thereby adjusting the height of the magnetic base 303, and thus the welding height of the small outfitting component being attracted.

[0033] To improve the stability of small outfitting parts during welding, the magnetic base 303 is designed as a bell-shaped structure, specifically, the cross-section of the magnetic base 303 is trapezoidal. This means that the upper surface of the magnetic base 303 is connected to the main adsorption rod 302, and the lower surface is adsorbed to the small outfitting part. The area of ​​the lower surface is larger than that of the upper surface. This ensures that the adsorption area between the magnetic base 303 and the small outfitting part is sufficiently large, ensuring that the small outfitting part can be effectively and stably adsorbed. This overcomes the shortcomings of single-point adsorption, effectively fixes the height of the small outfitting part, avoids stress displacement during welding, and thus ensures that the suspended small outfitting part does not wobble during welding and other operations, ensuring welding accuracy.

[0034] In order to further ensure that the welding position of the suspended small outfitting parts is stable and accurate, a number of auxiliary adsorption components are also included. Each of the auxiliary adsorption components is slidably installed on the extension member 2, and each of the auxiliary adsorption components can move relative to the main adsorption component 3, and then abut against the side of the small outfitting parts to stabilize the small outfitting parts. Each extension member 2 is slidably provided with an auxiliary adsorption component, and can move toward the main adsorption component 3 in the middle. After the main adsorption component 3 adsorbs the small outfitting parts, the welding position of the small outfitting parts is offset and can be adjusted by sliding the auxiliary adsorption components. Specifically, the auxiliary adsorption components in a certain direction are used to push the small outfitting parts to cause them to shift horizontally, and then adjust them to the accurate welding position. Since there are corresponding auxiliary adsorption components in each direction, that is to say, the adjustment of the small outfitting parts is all-round, ensuring that the welding position of the small outfitting parts is accurate.

[0035] In the scheme including the auxiliary adsorption component, in addition to adjusting the welding position of the small outfitting parts by pressing the auxiliary adsorption component, the auxiliary adsorption component can also adjust the welding position of the small outfitting parts by adsorption, as follows: the auxiliary adsorption component includes a transversely arranged auxiliary adsorption rod, and a magnet arranged on one end of the auxiliary adsorption rod. The small outfitting parts are adjusted by the magnetic attraction force generated by the magnet on the small outfitting parts. The magnet can be out of contact with the small outfitting parts, and only acts on the small outfitting parts through the magnetic attraction force to cause them to undergo slight displacement to achieve the purpose of fine-tuning, and this will not affect the position where the small outfitting parts need to be welded.

[0036] Optionally, the center of the first fixed workpiece 101 overlaps above the center of the second fixed workpiece 102, and a handle 6 is provided protruding above the center of the first fixed workpiece 101. The overlapping position of the first fixed workpiece 101 and the second fixed workpiece 102 is fixed by welding, and the handle 6 is provided to enable lifting. When the fixing device needs to be moved, it can be directly lifted by the handle 6 and moved to the desired installation position, or it can be moved in conjunction with the handle 6 through a mechanical structure.

[0037] Furthermore, the ends of the first fixed workpiece 101 and the second fixed workpiece 102 are each provided with two mounting holes. The extension member 2 is provided with a plurality of locking holes 201 that match the mounting holes, and the spacing between each locking hole 201 is equal to the spacing between the two mounting holes. At least two mounting holes are provided at each end of the two fixed workpieces. The locking member 4 passes through the mounting holes and engages with the locking holes 201 on the extension member 2 to lock the extension member 2 to the fixed workpiece. The provision of at least two mounting holes and the locking hole 201 ensures the stability of the connection. The locking member 4 can specifically be a screw or bolt.

[0038] To enhance the stability of the fixture installation, a base plate is provided with support holes arranged in a cross pattern. The bottom end of the support member 5 can be locked into these holes and rotated relative to the base plate to adjust the height of the bottom end of the main adsorption assembly 3. The bottom end of the support member 5 engages and locks with the support holes, ensuring the stability of the fixture through the flat base plate structure, minimizing the risk of shaking of the fixture and the adsorbed small outfitting. Multiple, evenly spaced support holes can be configured to accommodate diverse installation environments, ensuring accurate and stable welding of small outfitting even in complex installation environments.

[0039] In order to improve the structural strength of the fixing component 1, the first fixing workpiece 101 and the second fixing workpiece 102 are designed as angle steel structures, and reinforcing ribs can be added on them to ensure that the small outfitting parts are adsorbed and suspended in the air without any accidents of structural fracture, thereby ensuring the reliability and safety of the device.

[0040] It is worth mentioning that when it is necessary to assemble and weld two or more small outfitting parts at the same time, taking two as an example, two fixtures are used to absorb the two small outfitting parts that need to be welded, so that the positions of the two small outfitting parts correspond to each other before welding. In this process, due to the structural design of the fixture, the gap between the ends of the first fixed workpiece 101 and the second fixed workpiece 102 allows the two fixtures to be installed almost fittingly, or in other words, they can be installed cross-fittingly, so that the welding position of the small outfitting parts can be adjusted at any time, and the welding position can be guaranteed to be 100% accurately matched. In addition, two fixtures are used to assist in the welding of small outfitting parts. The welding process can be completed by only one operator. Compared with the traditional technology that requires at least three people to cooperate for welding, it undoubtedly greatly saves labor and improves the welding accuracy and efficiency.

[0041] In summary, the fixing device described in this application can be installed in any complex ship manufacturing environment, and can stably and effectively adsorb small outfitting parts, thereby completing stable and accurate welding of small outfitting parts, replacing the traditional manual fixing of small outfitting parts, ensuring the safety of operators, saving more manpower and material resources, and greatly improving welding work efficiency.
