Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a multi-angle positioning welding device for electrical control cabinet housings. Background Technology

[0002] As a key structural component of industrial power distribution and automation control systems, the manufacturing quality of electrical control cabinets directly affects the installation accuracy, protection level, and long-term operational reliability of internal components. Cabinets are typically constructed from bent and welded steel plates, characterized by multiple facets, weld seams, and complex spatial angles. Welding at intersections of different facets, such as fillet welds, inclined reinforcing ribs, and irregularly shaped mounting plates, places high demands on positioning accuracy, welding accessibility, and process consistency. While existing general-purpose welding robots can automate welding, for multi-angle, multi-position cabinet welds, expensive multi-axis positioners or customized fixtures are often required. These solutions involve complex programming, insufficient flexibility, and difficulty adapting to small-batch, multi-specification production needs. Uneven heating during continuous welding can easily cause cabinet deformation. Traditional fixing methods struggle to achieve dynamic anti-deformation adjustment or segmented welding collaborative control, resulting in significant subsequent correction work that affects dimensional accuracy and appearance.

[0003] According to patent number CN118951520A, a multi-angle welding equipment and method for positioning steel structural components has the technical effect of not needing to stop and wait when welding multiple steel plates, maintaining a continuous welding state, and not generating invalid working time, thus improving welding efficiency. However, this equipment lacks a means to fix irregular workpieces during welding, which makes it inconvenient to manufacture irregularly shaped electrical control cabinets. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a multi-angle positioning welding device for an electrical control cabinet, comprising a device base, a fixed end of a rotating table fixedly connected to the top of the device base, a fixed end of a first telescopic rod fixedly connected to the rotating end of the rotating table, a fixed end of a second telescopic rod fixedly connected to the movable end of the first telescopic rod, a welding gun fixedly connected to the movable end of the second telescopic rod, and a fixing device fixedly connected to the top of the device base at a position on one side of the rotating table; The fixing device includes a sliding frame, a lifting assembly fixedly connected to the top of the sliding frame, a sliding base sleeved and threadedly connected to the side of the lifting assembly, a fixed end of a fixed base rotatably connected to the side of the sliding base, an adjusting assembly fixedly connected to the end of the sliding base away from the fixed base, and the bottom of the sliding frame fixedly connected to the top of the equipment base. The bottom plate of the housing is placed on top of the rotating platform. Starting the rotating platform causes the bottom plate of the housing to rotate. Activating the first telescopic rod causes the second telescopic rod to move up and down. Activating the second telescopic rod causes the movable end of the second telescopic rod to move the welding torch, which then welds different positions on the housing. Components on the side of the housing are fixed to the fixed base. On the side, the fixed base is activated, which moves the workpiece on the side of the box and rotates it under the drive of the adjustment component. Multiple sets of fixed bases are used to fix different workpieces together, which facilitates the combination and welding of the box floor placed on top of the rotating table. This also facilitates the combination and splicing of different workpieces with the bottom of the box. The stability of the workpieces after movement is increased by the guiding setting of the lifting component and the sliding frame, so that the weld seams between different workpieces remain relatively stable when they come close to each other, thus ensuring the welding quality. This enables the combination and welding of box workpieces of different shapes, which is convenient for the manufacture of irregular-shaped boxes. At the same time, the rotating table allows for rotation and observation of the box from all sides, which facilitates visual inspection of the welding quality.

[0005] Preferably, the lifting assembly includes a first motor, a drive gear is fixedly connected to the drive shaft of the first motor, a driven gear meshes with the side of the drive gear, a screw is fixedly connected to the bottom of the driven gear, the screw passes through the side of the sliding base and is threadedly connected to the side of the sliding base, the bottom of the first motor is fixedly connected to the top of the sliding frame through a bracket, and the screw is rotatably connected to the side of the sliding frame through the bracket.

[0006] Preferably, the sliding base includes a sliding seat with a rotating groove on its side. A drive seat is fixedly connected to the side of the sliding seat away from the rotating groove, and a threaded sleeve is fixedly connected to the bottom of the drive seat. A screw passes through the bottom of the threaded sleeve and is threadedly connected to the bottom of the threaded sleeve. The side of the rotating groove is rotatably connected to the fixed end side of the fixed base. The sliding seat is sleeved on the side of the sliding frame and slidably connected to the side of the sliding frame. When the first motor is started, the drive shaft of the first motor rotates, driving the drive gear to rotate. The rotation of the drive gear drives multiple sets of driven gears to rotate synchronously. The rotation of the driven gears drives the screw to rotate. The rotation of the screw drives the threaded sleeve to move through the thread. The threaded sleeve rises and falls under the action of the screw thread, and the rotating groove facilitates the rotational connection between the fixed base and the sliding seat. The arrangement of the sliding seat sleeved on the side of the sliding frame increases the overall stability of the sliding seat. Furthermore, the synchronous rotation of multiple sets of screws driving the threaded sleeve to move disperses the supporting pressure of the fixed base and the adjusting component, stabilizing the center of the fixed workpiece, thereby facilitating the workpiece to maintain a stable state.

[0007] Preferably, the fixed base includes a polygonal base, the movable end of the third telescopic rod is fixedly connected to the side of the polygonal base, a spring is fixedly connected to the side of the polygonal base away from the third telescopic rod, a fixing component is fixedly connected to the side of the spring away from the polygonal base, the fixed end of the third telescopic rod is rotatably connected to the sliding seat through a rotating groove, and the fixed end of the third telescopic rod is fixedly connected to the side of the adjusting component.

[0008] Preferably, the fixing component includes a fixing frame. A limiting groove is formed at the top of the fixing frame. A rotating rod is rotatably connected through the bottom of the inner wall of the limiting groove. A limiting plate is fitted and fixedly connected to the side of the rotating rod inside the limiting groove. An air pump is fixedly connected to the rotating rod below the limiting plate. A fixed suction cup is fixedly connected to the side of the air pump. The side of the fixing frame is fixedly connected to the side of the spring. When the third telescopic rod and the air pump are activated, the movable end of the third telescopic rod moves the polygonal base. The movement of the polygonal base moves the spring, which in turn moves the fixing frame. The movement of the fixing frame moves the rotating rod, which in turn moves the air pump. The air pump then moves the fixed suction cup, which adheres to and fixes the side of the workpiece. The workpiece, fixed by the suction cup, moves along the drive of the third telescopic rod. The air pump helps maintain the attraction of the fixed suction cup to the side of the workpiece. While in surface contact, the pressure exerted by the irregularly shaped workpiece on the fixed suction cup causes the fixed suction cup to move along the irregular surface of the workpiece. This, in turn, causes the air pump to rotate under the constraint of the rotating rod. The rotation of the rotating rod causes the limiting plate to rotate as well. After the limiting plate rotates to a certain position, it is restricted by the limiting groove, which limits the rotation range of the limiting plate and thus the rotation range of the air pump. This gives the fixed suction cup a certain degree of self-adaptation to the surface of the workpiece. At the same time, the combination of the limiting plate and the inner wall of the limiting groove restricts the fixing range of the fixed suction cup. The air pump continuously applies pressure to the inside of the fixed suction cup, thus ensuring the fixing effect on the workpiece. Meanwhile, the spring sheet provides a certain pressure when the fixed suction cup contacts the workpiece, which facilitates elastic contact fixing and achieves compression of the side of the workpiece. The setting of multiple fixed suction cups on the side of the polygonal base and the self-adaptation range of the fixed suction cups facilitate combined fixing. This allows the workpiece on the side of the arc-shaped circular box to be fixed on the side of the fixed suction cup, which facilitates the welding between the special parts and the bottom plate of the box.

[0009] Preferably, the adjustment assembly includes a second motor, the drive shaft of the second motor is fixedly connected to a rotating seat, the side of the rotating seat is rotatably connected to a limit strip via a rotating shaft, the side of the limit strip is fixedly connected to a reset spring, the side of the rotating seat is sleeved and slidably connected to a release ring, the side of the release ring passes through and is slidably connected to a limit sliding frame, the side of the limit sliding frame is fixedly connected to the side of the sliding seat, and the side of the rotating seat is fixedly connected to the fixed end of the third telescopic rod.

[0010] Preferably, the release ring includes a pull ring, a brake ring is fixedly connected to the side of the pull ring, a release groove is fixedly connected to the side of the brake ring, a sliding hole adapted to the limiting sliding bracket is opened on the side of the pull ring, a pull plate is fixedly connected to the side of the pull ring, a movable end of a fourth telescopic rod is fixedly connected to the side of the pull plate, a return spring is fixedly connected to the side of the pull ring between the pull plate and the sliding hole, the side of the return spring is fixedly connected to the side of the second motor, and the fixed end of the fourth telescopic rod is fixedly connected to the side of the second motor. When the second motor is started, the drive shaft of the second motor rotates, causing the rotating seat to rotate. The rotation of the rotating seat causes the limiting strip to move. The limiting strip moves along the inner wall of the brake ring, and the inner wall of the brake ring squeezes the limiting strip, thereby causing the limiting strip to rotate along the side of the rotating seat. While the limiting strip rotates, it squeezes the return spring, and the squeeze of the return spring generates... The elastic force drives the limiting strip to rotate, thus locking the limiting strip inside the brake ring. The rotation of the rotating seat drives the third telescopic rod to rotate, which in turn drives the spring plate to rotate, thereby rotating the irregularly shaped workpiece to adapt to different welding angles. The cooperation between the limiting strip and the brake ring allows the workpiece to maintain a stable posture after rotating to a certain angle in one direction, facilitating the approach of weld seams and making welding easier. When released, the fourth telescopic rod is activated. The movable end of the fourth telescopic rod drives the pulling ring to move, which in turn drives the brake ring to move. The brake ring moves and causes the release groove to move, releasing the brake ring from the limiting strip. The pulling ring and the release groove slide under the constraint of the limiting sliding frame, facilitating the rotation of the rotating seat. After the pulling ring moves, it generates an elastic force on the return spring, causing the pulling ring to slide, thus facilitating the brake ring to re-engage with the limiting strip and re-fix the relative position of the irregularly shaped workpiece.

[0011] This invention provides a multi-angle positioning welding device for electrical control cabinet housings. It has the following beneficial effects: 1. This multi-angle positioning welding equipment for electrical control cabinet enclosures is equipped with a first telescopic rod. The cabinet base plate is placed on top of a rotating table, and starting the rotating table rotates the base plate. Activating the first telescopic rod drives a second telescopic rod to move up and down; activating the second telescopic rod moves the welding torch, allowing welding to be performed at different positions on the cabinet. Workpieces on the sides of the cabinet are fixed to the sides of fixed bases. Activating the fixed bases moves the workpieces, which then rotate under the drive of the adjusting components. Multiple sets of fixed bases are used to combine and fix different workpieces, facilitating welding with the cabinet base plate on the rotating table and achieving combined splicing of the workpieces and the cabinet bottom. The guiding design of the lifting components and sliding frame enhances the stability of the workpieces after movement, ensuring relatively stable weld seams between workpieces when they are close together, thus guaranteeing welding quality. This design allows for the combined welding of cabinet workpieces of different shapes, which is beneficial for the manufacturing of irregularly shaped cabinets. The rotating table also facilitates rotation and observation of the cabinet's perimeter, enabling visual inspection of welding quality.

[0012] 2. This multi-angle positioning welding equipment for the electrical control cabinet is equipped with driven gears. When the first motor is started, its drive shaft rotates the driving gear, which in turn drives multiple sets of driven gears to rotate synchronously. The driven gears drive the screw to rotate, and the screw moves the threaded sleeve through threaded transmission, achieving upward and downward movement. A rotating groove maintains a rotatable connection between the fixed base and the sliding seat; the sliding seat is fitted onto the side of the sliding frame, enhancing overall stability. The synchronous rotation of multiple sets of screws drives the movement of the threaded sleeve, distributing the supporting pressure of the fixed base and adjustment components, stabilizing the workpiece center, and thus maintaining the workpiece in a stable state.

[0013] 3. This multi-angle positioning welding equipment for the electrical control cabinet is equipped with a fixed frame. Activating the third telescopic rod and the vacuum pump causes the polygonal base to move, which in turn moves the fixed frame via a spring. The fixed frame, in turn, moves the vacuum pump and the fixed suction cup via a rotating rod, allowing the suction cup to adhere to the side of the workpiece. After the workpiece is fixed by the suction cup, it can move along the direction of the third telescopic rod. The vacuum pump maintains the suction force of the suction cup on the workpiece. When the suction cup contacts the surface of an irregularly shaped workpiece, the pressure of the workpiece on the suction cup causes the suction cup to move along its surface, thereby driving the vacuum pump to rotate under the constraint of the rotating rod. The rotating rod drives the limiting plate to rotate until the limiting plate stops under the constraint of the limiting groove, thus limiting the rotation range of the vacuum pump. This design allows the fixed suction cup to adapt to the surface shape of the workpiece, while the cooperation of the limiting plate and the limiting groove limits the fixing range. The vacuum pump continuously acts on the fixed suction cup to ensure reliable fixing; the spring provides elastic pressure upon contact, achieving flexible fixing. Multiple sets of suction cups arranged on the side of the polygonal base can be used in combination to fix workpieces on the side of the box, such as arc-shaped and circular ones, which facilitates the welding of special parts to the bottom plate of the box.

[0014] 4. This multi-angle positioning welding equipment for the electrical control cabinet is equipped with a second motor. The drive shaft of the second motor rotates, causing the rotating seat to rotate. The rotating seat causes the limiting strip to move along the inner wall of the brake ring. The inner wall of the brake ring applies a compressive force to the limiting strip, causing the limiting strip to rotate along the side of the rotating seat and compress the reset spring. The rebound force accumulated by the reset spring allows the limiting strip to engage inside the brake ring, achieving one-way locking. When the rotating seat rotates, the irregularly shaped workpiece is rotated via the third telescopic rod and the spring, thereby adjusting the welding angle. The cooperation between the limiting strip and the brake ring allows the workpiece to remain stable after rotating to a certain angle, facilitating weld butt joints and welding. When release is required, the fourth telescopic rod is activated. Its movable end drives the pull ring to move, causing the brake ring to shift. The release groove moves accordingly, thereby releasing the brake on the limiting strip. The pull ring and the release groove slide under the guidance of the limiting sliding frame, allowing the rotating seat to rotate freely. After being released, the return spring drives the pull ring to reset, causing the brake ring to re-contact the limit strip and restore the braking function, making it easier to reposition the workpiece.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: a multi-angle positioning welding device for an electrical control cabinet, including a device base 1, a fixed end of a rotating table 2 fixedly connected to the top of the device base 1, a fixed end of a first telescopic rod 3 fixedly connected to the rotating end of the rotating table 2, a fixed end of a second telescopic rod 4 fixedly connected to the movable end of the first telescopic rod 3, a welding gun 5 fixedly connected to the movable end of the second telescopic rod 4, and a fixing device 6 fixedly connected to the top of the device base 1 at a position on one side of the rotating table 2; The fixing device 6 includes a sliding frame 601, a lifting component 602 is fixedly connected to the top of the sliding frame 601, a sliding base 603 is sleeved and threadedly connected to the side of the lifting component 602, a fixed end of a fixed base 604 is rotatably connected to the side of the sliding base 603, an adjusting component 605 is fixedly connected to the end of the sliding base 603 away from the fixed base 604, and the bottom of the sliding frame 601 is fixedly connected to the top of the equipment base 1.

[0019] The bottom plate of the enclosure is placed on top of the rotating platform 2. When the rotating platform 2 is started, it rotates the bottom plate. The first telescopic rod 3 is activated, causing the second telescopic rod 4 to move up and down. The movable end of the second telescopic rod 4 then moves the welding torch 5, which welds different positions on the enclosure. Components on the side of the enclosure are fixed to the side of the fixed base 604. When the fixed base 604 is activated, it moves the components on the side of the enclosure and rotates under the drive of the adjusting component 605. Multiple sets of fixed bases 604 are used in this process. Different workpieces are combined and fixed to facilitate welding with the box floor placed on top of the rotating table 2. This allows for the assembly and splicing of different workpieces with the bottom of the box. The guiding arrangement of the lifting component 602 and the sliding frame 601 increases the stability of the workpieces after movement, ensuring that the welds between different workpieces remain relatively stable when they approach each other, thus ensuring welding quality. This enables the combination and welding of box workpieces of different shapes, facilitating the manufacturing of irregularly shaped boxes. At the same time, the rotating table 2 allows for rotational observation of the box's perimeter, facilitating visual inspection of the welding quality.

[0020] For the second embodiment, please refer to... Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the lifting assembly 602 includes a first motor 6021, the drive shaft of the first motor 6021 is fixedly connected to a drive gear 6022, the side of the drive gear 6022 is meshed with a driven gear 6023, the bottom of the driven gear 6023 is fixedly connected to a screw 6024, the screw 6024 passes through the side of the sliding base 603 and is threadedly connected to the side of the sliding base 603, the bottom of the first motor 6021 is fixedly connected to the top of the sliding frame 601 through a bracket, and the screw 6024 is rotatably connected to the side of the sliding frame 601 through the bracket.

[0021] The sliding base 603 includes a sliding seat 6031, a rotating groove 6032 is provided on the side of the sliding seat 6031, a drive seat 6033 is fixedly connected to the side of the sliding seat 6031 away from the rotating groove 6032, a threaded sleeve 6034 is fixedly connected to the bottom of the drive seat 6033, a screw 6024 passes through the bottom of the threaded sleeve 6034 and is threadedly connected to the bottom of the threaded sleeve 6034, the side of the rotating groove 6032 is rotatably connected to the fixed end side of the fixed base 604, and the sliding seat 6031 is sleeved on the side of the sliding frame 601 and is slidably connected to the side of the sliding frame 601.

[0022] The first motor 6021 is started, and the drive shaft of the first motor 6021 rotates, driving the drive gear 6022 to rotate. The rotation of the drive gear 6022 drives multiple sets of driven gears 6023 to rotate synchronously. The rotation of the driven gears 6023 drives the screw 6024 to rotate. The rotation of the screw 6024 drives the threaded sleeve 6034 to move. The threaded sleeve 6034 rises and falls under the action of the screw 6024, and the rotating groove 6032 facilitates the rotational connection between the fixed base 604 and the sliding seat 6031. The sliding seat 6031 is sleeved on the side of the sliding frame 601 to increase the overall stability of the sliding seat 6031. The synchronous rotation of multiple sets of screws 6024 driving the movement of the threaded sleeve 6034 disperses the supporting pressure of the fixed base 604 and the adjusting component 605, stabilizing the center of the fixed workpiece, thereby facilitating the workpiece to maintain a stable state.

[0023] Third embodiment, please refer to Figures 1-6 Based on the second embodiment, the present invention provides a technical solution: the fixed base 604 includes a polygonal base 6041, the movable end of a third telescopic rod 6042 is fixedly connected to the side of the polygonal base 6041, a spring piece 6043 is fixedly connected to the side of the polygonal base 6041 away from the third telescopic rod 6042, a fixing component 6044 is fixedly connected to the side of the spring piece 6043 away from the polygonal base 6041, the fixed end of the third telescopic rod 6042 is rotatably connected to the sliding seat 6031 through a rotating groove 6032, and the fixed end of the third telescopic rod 6042 is fixedly connected to the side of the adjusting component 605.

[0024] The fixing component 6044 includes a fixing frame 60441. A limiting groove 60442 is formed on the top of the fixing frame 60441. A rotating rod 60443 is rotatably connected through the bottom of the inner wall of the limiting groove 60442. A limiting plate 60444 is sleeved and fixedly connected to the side of the rotating rod 60443 inside the limiting groove 60442. An air pump 60445 is fixedly connected to the rotating rod 60443 below the limiting plate 60444. A fixing suction cup 60446 is fixedly connected to the side of the air pump 60445. The side of the fixing frame 60441 is fixedly connected to the side of the spring piece 6043.

[0025] Activating the third telescopic rod 6042 and the air pump 60445 causes the movable end of the third telescopic rod 6042 to move the polygonal base 6041. The movement of the polygonal base 6041 moves the spring 6043, which in turn moves the fixed frame 60441. The movement of the fixed frame 60441 then moves the rotating rod 60443, which in turn moves the air pump 60445. The movement of the air pump 60445 then moves the fixed suction cup 60446. 6. The workpiece is attracted and fixed to the side by the suction cup 60446. The workpiece moves along the drive of the third telescopic rod 6042 after being fixed by the suction cup 60446. The vacuum pump 60445 helps maintain the attraction of the suction cup 60446 to the side of the workpiece. While the suction cup 60446 is in contact with the side of the workpiece, the squeezing force of the irregularly shaped workpiece on the suction cup 60446 causes the suction cup 60446 to move along the irregular surface of the workpiece, thereby driving the vacuum pump 60445 to rotate under the constraint of the rotating rod 60443. The rotating rod 60443 drives the limiting plate 60444 to rotate. After the limiting plate 60444 rotates to a certain position, it is restricted by the limiting groove 60442, limiting the rotation range of the limiting plate 60444. This, in turn, limits the rotation range of the vacuum pump 60445, giving the fixed suction cup 60446 a certain degree of self-adaptation to the surface of the workpiece. At the same time, the combination of the limiting plate 60444 and the inner wall of the limiting groove 60442 restricts the fixing range of the fixed suction cup 60446, and the vacuum pump 60445 further restricts the fixing range of the fixed suction cup 60446. The continuous pressure applied to the part ensures the fixation of the workpiece. At the same time, the spring 6043 provides a certain pressure when the fixed suction cup 60446 contacts the workpiece, which facilitates elastic contact fixation and realizes the compression of the side of the workpiece. The multiple fixed suction cups 60446 on the side of the polygonal base 6041 and the adaptive range of the fixed suction cups 60446 facilitate combined fixation, so that the workpiece on the side of the arc-shaped and circular box is fixed on the side of the fixed suction cup 60446, which facilitates the welding between the special parts and the bottom plate of the box.

[0026] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the adjustment component 605 includes a second motor 6051, the drive shaft of the second motor 6051 is fixedly connected to a rotating seat 6052, the side of the rotating seat 6052 is rotatably connected to a limiting strip 6053 via a rotating shaft, the side of the limiting strip 6053 is fixedly connected to a reset spring 6054, the side of the rotating seat 6052 is sleeved and slidably connected to a release ring 6055, the side of the release ring 6055 passes through and is slidably connected to a limiting sliding frame 6056, the side of the limiting sliding frame 6056 is fixedly connected to the side of the sliding seat 6031, and the side of the rotating seat 6052 is fixedly connected to the fixed end of the third telescopic rod 6042.

[0027] The release ring 6055 includes a pull ring 60551, a brake ring 60552 fixedly connected to the side of the pull ring 60551, a release groove 60553 fixedly connected to the side of the brake ring 60552, a sliding hole 60554 adapted to the limiting sliding frame 6056 opened on the side of the pull ring 60551, a pull plate 60555 fixedly connected to the side of the pull ring 60551, a movable end of a fourth telescopic rod 60556 fixedly connected to the side of the pull plate 60555, a return spring 60557 fixedly connected to the side of the pull ring 60551 at a position between the pull plate 60555 and the sliding hole 60554, a side of the return spring 60557 fixedly connected to the side of the second motor 6051, and a fixed end of the fourth telescopic rod 60556 fixedly connected to the side of the second motor 6051.

[0028] The second motor 6051 is started. The drive shaft of the second motor 6051 rotates, causing the rotating seat 6052 to rotate. The rotation of the rotating seat 6052 causes the limiting strip 6053 to move. The limiting strip 6053 moves along the inner wall of the brake ring 60552, and the inner wall of the brake ring 60552 compresses the limiting strip 6053, causing the limiting strip 6053 to rotate along the side of the rotating seat 6052. At the same time, the limiting strip 6053 compresses the reset spring 6054. The compression of the reset spring 6054 generates elastic force, causing the limiting strip 6053 to rotate back, thus locking the limiting strip 6053 inside the brake ring 60552. The rotation of the rotating seat 6052 causes the third telescopic rod 6042 to rotate, which in turn causes the spring 6043 to rotate, thereby rotating the irregularly shaped workpiece to adapt to different welding angles. The limiting strip 6053 and the brake ring 60552... The coordination between the components allows the workpiece to maintain a stable posture after rotating to a certain angle in one direction, thus facilitating the approach of weld seams and welding. When released, the fourth telescopic rod 60556 is activated. The movable end of the fourth telescopic rod 60556 drives the pulling ring 60551 to move. The movement of the pulling ring 60551 drives the brake ring 60552 to move. The movement of the brake ring 60552 drives the release groove 60553 to move. The movement of the brake ring 60552 disengages from the brake on the limiting bar 6053. The pulling ring 60551 and the release groove 60553 slide under the restriction of the limiting sliding frame 6056, thus facilitating the rotation of the rotating seat 6052. After the pulling ring 60551 moves, it generates a spring force on the return spring 60557, causing the pulling ring 60551 to slide. This facilitates the brake ring 60552 to re-engage with the limiting bar 6053 for braking, thus facilitating the re-fixation of the relative position of the irregularly shaped workpiece.
