A welding device for processing an e-sports chair

Abstract

This invention discloses a welding device for processing gaming chairs, relating to the field of welding technology. It includes a worktable, a welding machine, a welding component, and a first component mounted thereon. When the drive shaft rotates in the reverse direction, it simultaneously drives the long and short curved rods to rotate, causing the insertion pins A and B to be inserted into the insertion holes of the silicone strip. This creates a bidirectional pressing force from both sides of the welding component's positioning structure. Simultaneously, the torque force of the torsion spring shaft maintains the stable deflection state of the relay rod, thereby providing a stable deflection constraint on the welding component. This constraint method, in conjunction with the downward positioning of the first component and the wrapping positioning of the second component, effectively limits the deflection and displacement of the welding component in the horizontal and vertical directions during welding, ensuring that the welding component is always in the preset welding position. This significantly improves welding accuracy, reduces the welding defect rate, and guarantees the structural consistency and connection strength of the gaming chair's welding components.

Description

Technical Field

[0001] This invention relates to the field of processing and welding technology, specifically a welding device for processing gaming chairs. Background Technology

[0002] The core load-bearing components of gaming chairs (backrest frame, seat cushion support, armrest connectors, etc.) are all welded from thin-walled steel pipes. The welded parts mostly include round pipes, square pipes and various irregularly shaped bent pipes. The requirements for the accuracy, adaptability and stability of the welding positioning are extremely high, and it is also necessary to meet the diverse and personalized processing needs of gaming chairs.

[0003] The welding devices used in the manufacturing process of gaming chairs mostly adopt a single downward positioning or simple clamping method. The positioning force point is singular, making it difficult to form a comprehensive and stable limiting constraint on the welded parts. This causes the welded parts to easily deflect and shift in the horizontal and vertical directions during the welding process, making it impossible to maintain the preset welding position. As a result, the welding accuracy is low, and welding defects such as weld seam misalignment and incomplete welding occur frequently. This not only affects the structural consistency and connection strength of the welded parts of the gaming chair, but also increases subsequent rework costs and reduces production efficiency.

[0004] In terms of clamping welded parts, existing devices mostly use rigid clamping structures. These structures cannot conform to the surface contours of the welded parts, especially for irregularly shaped welded parts commonly found in the processing of gaming chairs. Rigid clamping can easily cause scratches and deformation on the surface of the welded parts, damaging the integrity of the product's appearance. At the same time, rigid clamping structures have poor adaptability and cannot flexibly adapt to welded parts of different sizes and contours. For welded parts of different specifications or irregular shapes, it is necessary to frequently change the positioning fixtures, which not only increases processing costs but also seriously affects processing efficiency, making it difficult to meet the diverse and personalized processing needs of gaming chairs.

[0005] Furthermore, the positioning stability of existing welding devices is insufficient. Although some devices attempt to use adsorption positioning, they are mostly single-point or few adsorption structures, which cannot form adsorption support in multiple ranges and directions. As a result, the welded parts are still not firmly positioned and are prone to displacement due to welding vibration. At the same time, for irregularly shaped gaming chair welded parts with large surface contours and irregular shapes, the existing positioning structure cannot achieve adaptive fitting, and the positioning accuracy and stability are further reduced. This makes it difficult to guarantee the welding quality of such irregularly shaped parts, which has become an important bottleneck restricting the improvement of the processing quality of gaming chairs.

[0006] Therefore, this invention proposes a welding device for processing gaming chairs to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a welding device for processing gaming chairs, thereby solving the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a welding device for processing e-sports chairs, comprising: a workbench, a welding machine, a welding component, and a first component mounted thereon. The first component comprises: a lifting and positioning frame fixedly connected to the workbench by bolts. The lifting and positioning frame consists of upper and lower parallel connecting frames and a drive screw arranged vertically and symmetrically in the middle of the connecting frames. A connecting rod is vertically connected to the lifting and positioning frame, and a quick clamp is fixedly connected to the end of the connecting rod away from the lifting and positioning frame. The first component also includes: a fixing strip fixedly connected to the end of the connecting rod away from the lifting positioning frame; both ends of the upper surface of the fixing strip are fixedly connected to positioning rods; a drive shaft is fixedly connected to the positioning rod away from the fixing strip; a cam is fixedly connected to the outer ring of the drive shaft; two sets of cams are symmetrically arranged around the central axis of the drive shaft; a pressing rod is attached to the bottom surface of the cam; the pressing rod is set perpendicular to the fixing strip and extends downward and slides within the fixing strip; an auxiliary spring is sleeved on the outer ring of the pressing rod; both ends of the auxiliary spring are fixedly connected to the pressing rod and the fixing strip respectively; the pressing rod extends downward through the fixing strip and is fixedly connected to a pressing plate. It also includes a second component for welding components for wrap-around positioning gaming chairs.

[0009] Preferably, the connecting rod is bent at a 90-degree angle.

[0010] Preferably, one end of the drive shaft has a built-in drive device, the cam is configured as an eccentric wheel, and two sets of the pressure rods are arranged around the central axis of the fixed bar, and respectively conform to and abut against the bottom surface of the cam.

[0011] Preferably, the second component includes: a central shaft strip fixedly connected to the bottom of the lower pressure plate, a silicone strip fixedly connected to the bottom of the central shaft strip, the silicone strip and the central shaft strip being arranged in a cross shape on the same horizontal plane, an elastic conforming block being embedded inside the silicone strip, insertion holes being provided at both ends of the upper surface of the silicone strip, the insertion holes being arranged at an angle, a main air pipe being fixedly connected to one side of the silicone strip, and multiple sets of adsorption plates arranged on the bottom surface of the silicone strip, with branch tubes fixedly connected to the upper end of the adsorption plates; It also includes a third component for automatic qualifying.

[0012] Preferably, the central shaft is set perpendicular to the lower pressure plate and parallel to the workpiece to be welded, the elastic contour block is a micro-U-shaped metal strip that bends upward, the other end of the main air pipe is connected to a small air pump, and the branch conduit is opened in the silicone strip and connected to the main air pipe.

[0013] Preferably, the third component includes a long curved rod and a short curved rod fixedly connected to the outer ring of the drive shaft. The long curved rod extends away from the lifting positioning frame and bends downward. A plug-in post A is fixedly connected to the end of the long curved rod away from the drive shaft. The short curved rod extends towards the lifting positioning frame and bends downward. The extension length of the short curved rod is half that of the long curved rod.

[0014] Preferably, the third component also includes a connector fixedly connected to the side of the lower pressure plate near the lifting positioning frame. The connector extends upwards, and a torsion spring shaft is rotatably connected to the end of the connector away from the lower pressure plate. A relay rod is fixedly connected to the torsion spring shaft, and the middle part of the relay rod is fixedly connected to the torsion spring shaft. The upper end of the relay rod abuts against the lower end of the short curved rod under the action of the torsion spring shaft. A plug-in post B is fixedly connected to the bottom end of the relay rod near the lower pressure plate.

[0015] Preferably, both the insertion post A and the insertion post B are adapted to be inserted into the insertion hole, and the contact surfaces of the lower end of the short curved rod and the upper end of the relay rod are both set as rectangular surfaces.

[0016] Compared with the prior art, the present invention provides a welding device for processing gaming chairs, which has the following beneficial effects: 1. When the drive shaft rotates in the reverse direction, it simultaneously drives the long and short curved rods to rotate, causing the insertion pins A and B to be inserted into the insertion holes of the silicone strips. This creates a bidirectional compressive force from both sides of the welding part positioning structure. Simultaneously, the torque force of the torsion spring shaft maintains the stable deflection of the relay rods, thus providing a stable deflection constraint on the welding part. This constraint method, in conjunction with the downward positioning of the first component and the wrapping positioning of the second component, effectively limits the deflection and displacement of the welding part in the horizontal and vertical directions during welding, ensuring that the welding part is always in the preset welding position. This significantly improves welding accuracy, reduces the welding defect rate, and guarantees the structural consistency and connection strength of the gaming chair's welding parts.

[0017] 2. When the second component moves down with the lower pressure plate and comes into contact with the welded part, the welded part squeezes the concave surface of the elastic contour block, causing its two ends to bend downwards and deform, thus presenting a semi-enclosed trend around the welded part on both sides. This semi-enclosed structure can not only fit the surface contour of the welded part and form a circumferential flexible clamping for the welded part, avoiding scratches and deformation on the surface of the welded part caused by rigid compression, but also provide stable support for the welded part and prevent displacement caused by vibration during the welding process. At the same time, the metal material of the elastic contour block has good elastic restoring ability, adapts to welded parts of different sizes and contours, improves the positioning adaptability of the device, and has a simple structure, long service life, and reduces the maintenance cost of the device.

[0018] 3. By arranging multiple sets of adsorption plates on the bottom surface of the silicone strip, and coordinating with airflow control of the main air pipe and branch pipes, multiple ranges and directions of pressure points are provided for the welded parts, effectively solving the problems of single pressure points and insufficient positioning stability in traditional positioning methods. The adsorption plates are adsorbed onto the surface of the welded parts by the negative pressure generated by the air pump. The evenly arranged multiple sets of adsorption plates can form multiple points of synchronous adsorption on the upper surface of the welded parts, dispersing the positioning pressure and avoiding deformation of the welded parts caused by excessive local pressure. At the same time, the multiple ranges of pressure points can limit the welded parts from different directions, further restricting the lateral and longitudinal displacement of the welded parts. This is especially suitable for positioning irregular structures in the welded parts of gaming chairs, ensuring the stability of the welded parts' posture during the welding process, reducing problems such as weld seam misalignment and incomplete welding, and improving welding quality and work efficiency. In addition, the adsorption pressure points are detachable and non-damaging, and will not damage the surface of the welded parts, ensuring the appearance integrity of the welded parts of the gaming chair.

[0019] 4. Through the deformation adaptation of the elastic contouring block and the distributed design of multiple sets of adsorption plates, for welded parts with high irregularity and large surface contour undulations, when the elastic contouring block is squeezed by the welded part, it will adaptively deform according to the undulations of the irregular contour. Its semi-enveloping range will expand as the irregular contour extends, conforming to the various protrusions and depressions on the irregular surface. At the same time, multiple sets of adsorption plates can correspond to different surface areas of the irregular welded part, forming more contact adsorption points. The higher the degree of irregularity and the more complex the surface contour of the welded part, the wider the contact point distribution of the adsorption plates, and the higher the wrapping fit of the elastic contouring block. This adaptive contact wrapping design allows the device to flexibly adapt to various irregular gaming chair welded parts without changing the positioning structure for different irregular parts, reducing processing costs, improving the versatility and processing flexibility of the device, and meeting the diverse and personalized processing needs of gaming chairs.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] Example

[0025] Please refer to Figures 1 to 7 As shown: To address the problems mentioned in the technical solutions, this invention provides a welding device for processing gaming chairs, comprising: a workbench 11, a welding machine 12, a welding component 13, and a first component mounted thereon. The first component includes: a lifting and positioning frame 21 fixedly connected to the workbench 11 by bolts. The lifting and positioning frame 21 consists of upper and lower parallel connecting frames and a drive screw vertically and symmetrically arranged in the middle of the connecting frames. A connecting rod 22 is vertically connected to the lifting and positioning frame 21. The connecting rod 22 is used to coordinate with the drive screw in the lifting and positioning frame 21 to control the up and down movement of the first component to adapt to different welding height requirements for gaming chairs. A quick clamp 23 is fixedly connected to the end of the connecting rod 22 away from the lifting and positioning frame 21. The first component also includes: a fixing strip 2305 fixedly connected to the end of the connecting rod 22 away from the lifting positioning frame 21; positioning rods 2306 are fixedly connected to both ends of the upper surface of the fixing strip 2305; the positioning rods 2306 are used to connect the fixing strip 2305 and support the drive shaft 2301; the positioning rods 2306 are fixedly connected to the drive shaft 2301 away from the fixing strip 2305; a cam 2302 is fixedly connected to the outer ring of the drive shaft 2301; the cam 2302 is used to rotate with the drive shaft 2301 and to press the auxiliary spring body 2304 downward under the action of its convex side; two sets of cams 2302 are symmetrically arranged around the central axis of the drive shaft 2301; a pressing rod 2303 is attached to the bottom surface of the cam 2302; the pressing rod 2303 is perpendicular to the fixing rod 2301. A strip 2305 is provided and extends downward to slide within the fixed strip 2305. An auxiliary spring body 2304 is sleeved on the outer ring of the lower pressure rod 2303. The auxiliary spring body 2304 is used to reset the lower pressure rod 2303 and to provide buffer for the movement of the lower pressure rod 2303 when the cam 2302 rotates and presses the lower pressure rod 2303 downward. The two ends of the auxiliary spring body 2304 are fixedly connected to the lower pressure rod 2303 and the fixed strip 2305 respectively. The lower pressure rod 2303 extends downward through the fixed strip 2305 and is fixedly connected to the lower pressure plate 2307. The lower pressure plate 2307 moves downward with the auxiliary spring body 2304 and approaches the welded part 13 placed on the worktable 11. The lower pressure plate 2307 is used to provide an installation and adjustment platform for the second and third components. It also includes a second component for the welding part 13 of the wrap-around positioning gaming chair.

[0026] The connecting rod 22 is set as a 90-degree bent rod.

[0027] The drive shaft 2301 has a built-in drive device at one end, the cam 2302 is set as an eccentric wheel, and the pressure rod 2303 is set in two sets with the central axis of the fixed strip 2305 as the center, and respectively fits and abuts against the bottom surface of the cam 2302.

[0028] The second component includes: a central shaft strip 31 fixedly connected to the bottom of the lower pressure plate 2307; a silicone strip 32 fixedly connected to the bottom of the central shaft strip 31; the silicone strip 32 moves toward the welding part 13 in conjunction with the lower pressure plate 2307 and contacts the upper surface of the welding part 13; under the action of mutual resistance with the welding part 13, the welding part 13 squeezes the concave surface of the elastic contour block 33, causing its two ends to bend downwards and deform; during the deformation process, the elastic contour block 33 tends to wrap around both sides of the welding part 13; and multiple sets of adsorption plates 37 on the lower surface of the silicone strip 32 adhere to the welding part 13. Adsorption at different prices provides multi-directional force points based on the shape of the different welded parts 13. The more irregular the outer ring surface, the more contact points it covers. The silicone strip 32 and the central shaft strip 31 are arranged in a cross shape on the same horizontal plane. An elastic contour block 33 is embedded and connected inside the silicone strip 32. Insertion holes 34 are opened at both ends of the upper surface of the silicone strip 32. The insertion holes 34 are arranged at an angle. A main air pipe 35 is fixedly connected to one side of the silicone strip 32. Multiple sets of adsorption plates 37 are arranged on the bottom surface of the silicone strip 32. A branch pipe 36 is fixedly connected to the upper end of the adsorption plate 37. It also includes a third component for automatic qualifying.

[0029] The central shaft strip 31 is set perpendicular to the lower pressure plate 2307 and is parallel to the workpiece to be welded. The elastic contour block 33 is a micro-U arc-shaped metal strip that bends upward. The other end of the main air pipe 35 is connected to a small air pump. The branch conduit 36 ​​is opened inside the silicone strip 32 and is connected to the main air pipe 35. Two sets of silicone strips 32 and adsorption plate 37 are arranged in parallel. The two sets of silicone strips 32 and the welding part 13 are arranged in a cross shape on the vertical plane.

[0030] A further embodiment: Please refer to Figures 7 to 9 As shown: The third component includes a long curved rod 41 and a short curved rod 43 fixedly connected to the outer ring of the drive shaft 2301. Both the long curved rod 41 and the short curved rod 43 rotate with the reverse deflection of the drive shaft 2301. The long curved rod 41 extends away from the lifting positioning frame 21 and bends downward. The long curved rod 41 rotates in the opposite direction with the drive shaft 2301 and, together with the insertion post A42, is inserted into the insertion hole 34 on the silicone strip 32, forming a compressive force on the silicone strip 32. The end of the long curved rod 41 away from the drive shaft 2301 is fixedly connected to the insertion post A42. The short curved rod 43 extends towards the side close to the lifting positioning frame 21 and bends downward. The extension length of the short curved rod 43 is half that of the long curved rod 41.

[0031] The third component also includes a connector 44 fixedly connected to the side of the lower pressure plate 2307 near the lifting positioning frame 21. The connector 44 extends upward, and a torsion spring shaft 45 is rotatably connected to the end of the connector 44 away from the lower pressure plate 2307. A relay rod 46 is fixedly connected to the torsion spring shaft 45. The short curved rod 43 follows the drive shaft 2301 and deflects in the opposite direction. Its bottom end pushes the relay rod 46 to rotate in the forward direction around the torsion spring shaft 45, so that the insertion post B47 approaches the insertion hole 34 on the silicone strip 32 and is inserted into the insertion hole 34. Inside, a squeezing force is formed on the other side of the silicone strip 32, and under the continuous pushing action of the short bending rod 43 based on the relay rod 46, the relay rod 46 is kept in a deflected state. The middle part of the relay rod 46 is fixedly connected to the torsion spring shaft 45. Under the torque force of the torsion spring shaft 45, the relay rod 46 maintains a reverse deflection force and is in contact with the lower end of the short bending rod 43. The upper end of the relay rod 46 is in contact with the lower end of the short bending rod 43 under the action of the torsion spring shaft 45. The bottom end of the relay rod 46 is fixedly connected to the side near the lower pressure plate 2307 with a plug-in post B47.

[0032] Among them, the front ends of the plug-in pins A42 and B47 are semi-circular. When they are pulled out into the plug-in hole 34, due to the large semi-circular front end, there is stress between them and the plug-in hole 34. This force causes the plug-in pins A42 and B47 to pull the elastic contour block 33 to return to its original state through the plug-in hole 34, which prepares for subsequent work.

[0033] Both the plug-in pin A42 and the plug-in pin B47 are plugged into the plug-in hole 34. The contact surfaces between the lower end of the short curved rod 43 and the upper end of the relay rod 46 are both set as rectangular surfaces.

[0034] The working principle of all the content in the above embodiments is as follows: When in use, before starting the device, place the steel pipe frame welding part 13 of the gaming chair to be welded stably on the workbench 11 and arrange it according to its welding composition so that the welding points of multiple welding parts 13 are connected and correspond. The lifting and positioning frame 21 is fixed on the workbench 11 with bolts. Adjust the lifting and positioning frame 21 in the first component according to the specific height welding requirements of the welding part 13. The lifting and positioning frame 21 consists of upper and lower parallel connecting frames and a drive screw arranged vertically and symmetrically in the middle of the connecting frame. It is vertically connected to the connecting rod 22. By driving the drive screw in the lifting and positioning frame 21 to rotate, it works in conjunction with the connecting rod 22, which is set at a 90-degree bend, to drive the entire first component and the second and third components connected to it to move up and down until the second and third components move to a height position that matches the welding part 13, thus completing the height matching and ensuring the accuracy of subsequent positioning and welding operations.

[0035] After the height adjustment is completed, the quick clamp 23 in the first component is activated. One end of the drive shaft 2301 in the quick clamp 23 has a built-in drive device. After the drive device is activated, the drive shaft 2301 begins to rotate in the reverse direction. The two sets of symmetrically arranged cams 2302 fixedly connected to its outer ring rotate synchronously with the drive shaft 2301. Since the cam 2302 is an eccentric wheel structure, during its rotation, the protruding side will generate a downward squeezing force on the bottom pressure rod 2303 that is in contact with the bottom surface. The pressure rod 2303 has two sets of symmetrically arranged around the central axis of the fixing bar 2305. Under the action of the squeezing force, the pressure rod 2303 slides downward along the fixing bar 2305, and the auxiliary spring body 2304 sleeved on its outer ring is compressed. The auxiliary spring body 2304 provides a buffer for the downward movement of the pressure rod 2303 to avoid excessive pressure and damage to the welded part 13. On the other hand, it stores elastic force for the subsequent reset of the pressure rod 2303.

[0036] The pressure bar 2303 extends downward through the fixing bar 2305, and the pressure plate 2307 fixedly connected to its bottom end moves downward accordingly, simultaneously driving the second component fixedly connected to the bottom of the pressure plate 2307 to move closer to the welded part 13. In the second component, the central axis strip 31 is set perpendicular to the lower pressure plate 2307 and parallel to the welding part 13 to be welded. The silicone strip 32 fixedly connected to the bottom of the central axis strip 31 is arranged in a cross shape on the same horizontal plane as the central axis strip 31, and two sets of silicone strips 32 are arranged in parallel. The two sets of silicone strips 32 are arranged in a cross shape with the welding part 13 on the vertical plane to ensure full contact with the welding part 13. When the silicone strip 32 contacts the upper surface of the welding part 13, under the continuous downward pressure, the welding part 13 squeezes the elastic contour block 33 embedded inside the silicone strip 32. The elastic contour block 33 is an upwardly curved micro-U arc-shaped metal strip. Under the action of the extrusion force, its two ends bend downward and deform. During the deformation process, it tends to wrap around the welding part 13 on both sides, realizing flexible wrapping and positioning of the welding part 13.

[0037] Simultaneously, a small air pump at the other end of the main air pipe 35, which is fixedly connected to one side of the silicone strip 32, is activated. The airflow enters the main air pipe 35 through the branch conduit 36 ​​opened inside the silicone strip 32, so that the multiple sets of adsorption plates 37 arranged on the bottom surface of the silicone strip 32 are in a vacuum adsorption state. The adsorption plates 37 adhere to and adsorb the outer surface of the welded part 13. According to the irregular surface characteristics of different welded parts 13, multiple directional force points are provided. The more irregular the outer ring surface of the welded part 13, the more contact points of the adsorption plates 37 are distributed and the wider the range, further improving the stability of the positioning and preventing the welded part 13 from shifting during the welding process.

[0038] While the second component completes the positioning of the welded part 13, the third component starts simultaneously to automatically limit the second component and further enhance the positioning effect. In the third component, the long curved rod 41 and the short curved rod 43, which are fixedly connected to the outer ring of the drive shaft 2301, rotate synchronously with the reverse rotation of the drive shaft 2301. The long curved rod 41 extends away from the lifting positioning frame 21 and bends downward. The insertion post A42, which is fixedly connected to the end away from the drive shaft 2301, rotates with the long curved rod 41 and inserts into the inclined insertion holes 34 opened at both ends of the upper surface of the silicone strip 32. After insertion, a stable compressive force is formed on one side of the silicone strip 32, which restricts the lateral displacement of the silicone strip 32.

[0039] The short curved rod 43 extends towards the side near the lifting and positioning frame 21 and bends downward. Its extension length is half that of the long curved rod 41. When the drive shaft 2301 deflects in the opposite direction, its bottom end pushes the relay rod 46 fixedly connected to the torsion spring shaft 45. The torsion spring shaft 45 is rotatably connected to the top of the connector 44 fixed on the side of the lower pressure plate 2307 near the lifting and positioning frame 21. Under the thrust of the short curved rod 43, the relay rod 46 rotates forward about the torsion spring shaft 45 as the axis. The insertion post B47 fixedly connected to the bottom end near the side of the lower pressure plate 2307 moves towards the insertion hole 34 on the silicone strip 32 and inserts into the insertion hole 34, forming a squeezing force on the other side of the silicone strip 32. Due to the torque force of the torsion spring shaft 45, the relay rod 46 maintains a reverse deflection force, and its upper end is in close contact with the rectangular contact surface of the lower end of the short bending rod 43. Under the continuous thrust of the short bending rod 43, the relay rod 46 maintains a stable deflection state, thereby making the insertion post B47 stably inserted into the insertion hole 34. It works in conjunction with the insertion post A42 to form a bidirectional compression constraint on the silicone strip 32 from both sides, ensuring that the second component is stably and reliably positioned on the welded part 13.

[0040] Once the weldment 13 is positioned and securely fixed, the welding machine 12 on the workbench 11 is started to perform welding operations on the preset welding position of the weldment 13. After welding is completed, the welding machine 12 is turned off, the air pump stops working, and the suction plate 37 releases its suction on the weldment 13; at the same time, the drive shaft 2301 is controlled to rotate forward, and the cam 2302 rotates forward accordingly, releasing the pressure on the lower pressure rod 2303, the auxiliary spring 2304 resets, and pushes the lower pressure rod 2303 to move upward, causing the lower pressure plate 2307 and the second and third components to move upward synchronously and detach from the weldment 13.

[0041] At the same time, the long bending rod 41 and the short bending rod 43 rotate forward with the drive shaft 2301, and the plug-in pins A42 and B47 disengage from the plug-in hole 34 respectively, releasing the restriction on the silicone strip 32; the relay rod 46 rotates in the opposite direction to reset under the torque force of the torsion spring shaft 45, waiting for the next operation.

[0042] Finally, the welded part 13 is removed from the workbench 11, completing a full welding process for the gaming chair.
