Description

Technical Field

[0001] This invention relates to the field of workpiece fixing technology, specifically to a welding and positioning fixture for electromechanical pipeline supports. Background Technology

[0002] Mechanical and electrical pipeline supports are typically formed by welding together multiple profile components, such as... Figure 4 As shown, it can be formed by welding together two lateral supports and an intermediate support located between the two lateral supports. During the processing, it is usually necessary to first place each profile at the welding station and keep each profile in a predetermined relative position in order to carry out subsequent welding operations.

[0003] However, in the existing processing methods, each profile usually needs to be manually arranged, positioned and fixed before welding, which results in poor operation continuity and a long preparation time before welding, affecting the production efficiency of electromechanical pipeline supports. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of low efficiency in the workpiece positioning and fixing operation before welding in the existing electromechanical pipeline support welding process, and to propose an electromechanical pipeline support welding positioning fixture.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A welding and positioning fixture for electromechanical pipeline supports includes a support body, the support body comprising two first supports and a second support located between the two first supports, and further comprising: The welding table is used to support the bracket body; The driving component includes a first moving part and a second moving part that move along the same positioning direction; A positioning clamping assembly is connected to the driving assembly. The positioning clamping assembly includes a first positioning clamping assembly and a second positioning clamping assembly respectively disposed corresponding to the first bracket and the second bracket. The first positioning clamping component and the second positioning clamping component move along the positioning direction with the first moving component and the second moving component, respectively, to clamp and fix the first bracket and the second bracket.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the driving component also includes: A slide rail is fixedly connected to the welding table, and both the first moving part and the second moving part are slidably connected to the slide rail; A horizontal drive component is fixedly connected to the welding table; A connecting member is disposed on the moving end of the horizontal drive member and is connected to the first moving member and the second moving member.

[0008] Furthermore, the connecting member includes: A round rod is fixedly connected to the moving end of the horizontal drive component, and the first moving component and the second moving component are sleeved on the outside of the round rod; At least two positioning parts are fixedly connected to the round rod; A first elastic element is connected between the positioning part and the first moving part, and / or between the positioning part and the second moving part.

[0009] Furthermore, the first positioning and clamping component includes: At least two mounting parts are slidably connected to the first moving member and are capable of moving relative to the first moving member in a direction perpendicular to the slide rail; An elastic adsorption part is disposed on the mounting part and is oriented toward the first bracket.

[0010] Furthermore, the first positioning and clamping component also includes: A slide rail is formed on the surface of the slide rail, and the slide rail includes a first slide rail section and a second slide rail section that are interconnected. A pulley is fixedly connected to the mounting part and slidably disposed within the slide rail; The first slide section and the second slide section are arranged sequentially along the extension direction of the slide rail, and the two have different lateral spacings relative to the first bracket, so as to drive the mounting part to move laterally relative to the first moving member through the pulley.

[0011] Furthermore, the elastic adsorption portion includes: The mounting post is fixedly connected to the mounting part; The second elastic element is disposed on the side of the mounting post facing the first bracket; A magnetic attractor is connected to the end of the second elastic member away from the mounting post and is used to magnetically attract and engage with the first bracket.

[0012] Furthermore, the second positioning clamping component includes: A hinged base is fixedly connected to the second movable member; Flip the fixing plate and hinge it to the hinge seat; The lifting plate is slidably connected to the hinge seat and abuts against the flip-fixed plate. The support member is connected at one end to the lifting plate and at the other end to the positioning part near the second moving member.

[0013] Furthermore, the support member includes: The first universal ball joint is fixedly connected to the positioning part near the second moving member; The second omnidirectional ball joint is fixedly connected to the lifting plate; The omnidirectional ball joint connecting rod is movably connected at both ends to the first omnidirectional ball seat and the second omnidirectional ball seat, respectively.

[0014] Furthermore, the hinge seat and the flip-fixed plate are hinged by a pin, and a coil spring is provided on the hinge seat. One end of the coil spring is connected to the pin, and the other end is connected to the hinge seat.

[0015] Furthermore, the welding station is provided with a first protruding ridge and a second protruding ridge at its edge. The first protruding ridge abuts against the first bracket, and the second protruding ridge abuts against the second bracket.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This invention provides a unified working benchmark for the support body through a welding station, enabling the two first and second supports to complete subsequent positioning at the same workstation. A drive assembly moves different moving parts along a preset direction, allowing the cooperating clamping structure to apply limiting effects to the profiles in lateral and intermediate positions, thus transforming the originally dispersed placement, positioning, and fixing processes into a continuous, coordinated operation. This reduces the workload of operators repeatedly adjusting and individually fixing each profile, shortens the pre-welding preparation time, and allows the profiles to form a stable assembly more quickly before entering the welding process. Simultaneously, each clamping structure constrains different support positions, helping to maintain the relative positional stability of the support body before welding, reducing the impact of manual operation differences on the positioning results, thereby improving the continuity and overall production efficiency of electromechanical pipeline support welding.

Detailed Implementation

[0019] 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.

[0020] In existing electromechanical pipeline support welding processes, multiple profile parts typically need to be placed, aligned, and fixed sequentially by operators before welding. This dispersed workpiece positioning and fixing process requires significant manual intervention, often resulting in lengthy pre-welding preparation time. Therefore, this application provides a welding positioning fixture for electromechanical pipeline supports, enabling the first and second supports to achieve a stable positioning state on the same welding station, thereby improving the efficiency of pre-welding positioning and fixing.

[0021] The present invention provides a welding and positioning fixture for electromechanical pipeline supports, comprising a support body 1, the support body 1 including two first supports 11 and a second support 12 located between the two first supports 11, and further comprising: Welding table 2 is used to support the support body 1; The drive assembly 3 includes a first moving part 31 and a second moving part 32 that move along the same positioning direction; The positioning clamping component 4 is connected to the driving component 3. The positioning clamping component 4 includes a first positioning clamping component 41 and a second positioning clamping component 42 respectively corresponding to the first bracket 11 and the second bracket 12. The first positioning clamping component 41 and the second positioning clamping component 42 move along the positioning direction with the first moving component 31 and the second moving component 32 respectively, so as to clamp and fix the first bracket 11 and the second bracket 12.

[0022] like Figure 4 As shown, the support body 1 includes two first supports 11 and a second support 12 located between the two first supports 11. The two first supports 11 can form a lateral support structure, and the second support 12 can form an intermediate connection or intermediate reinforcement structure. In this embodiment, the welding table 2 serves as a basic platform for welding operations, providing a unified placement benchmark for multiple profile parts and avoiding positioning errors caused by the scattered placement of various profile parts.

[0023] Specifically, the drive assembly 3 provides the power for the positioning action, and the positioning clamping assembly 4 converts this power into a limiting effect on different profile parts. During operation, the first bracket 11 and the second bracket 12 are first placed on the welding table 2. Then, the drive assembly 3 actuates, causing the first positioning clamping assembly 41 and the second positioning clamping assembly 42 to enter their respective clamping areas, thereby constraining the side and center profile parts. Thus, the pre-welding alignment and fixing of multiple profile parts can be continuously completed on the same fixture, reducing the need for manual adjustment and clamping of each part individually.

[0024] In other embodiments of this application, to further improve feeding efficiency, such as Figure 2 As shown, a feeding assembly 5 can also be installed on one side of the welding table 2. The feeding assembly 5 is used to place the first support 11 and the second support 12 within the working area of ​​the welding table 2, which can further improve the overall work efficiency. The feeding assembly 5 can be one of a roller conveyor, a chain conveyor mechanism, or a robotic transfer mechanism. Through the above structure, feeding, positioning, and clamping can be formed into a continuous process, thereby shortening the preparation time before welding and improving the processing efficiency of electromechanical pipeline supports.

[0025] In other embodiments of this application, to further improve the material unloading efficiency after welding, a material unloading component 6 may also be provided on the welding table 2. For example... Figure 2As shown, the feeding assembly 6 includes several transmission rollers 61, a synchronous belt component 62, and a power component 63. The transmission rollers 61 are rotatably mounted on the welding table 2. Adjacent transmission rollers 61 are linked by the synchronous belt component 62, and the power component 63 is driven by one of the transmission rollers 61. Thus, when the power component 63 is activated, it drives the transmission roller 61 connected to it to rotate, and the power is sequentially transmitted to the remaining transmission rollers 61 via the synchronous belt component 62, causing all transmission rollers 61 to rotate synchronously in the same direction.

[0026] Specifically, the welding table 2 has a groove corresponding to the transfer roller 61, with at least a portion of the transfer roller 61 located within the groove, allowing the first support 11 to contact the transfer roller 61 when placed on the welding table 2. After welding is completed, the power component 63 drives the transfer roller 61 to rotate. The transfer roller 61, through friction with the first support 11, moves the welded support body 1 as a whole, thus achieving automatic unloading. By setting the unloading component 6, manual handling of the finished support can be reduced, improving the continuous operation capability of the tooling and overall processing efficiency.

[0027] In a preferred embodiment, the present invention may be further configured such that the driving component 3 further includes: The slide rail 33 is fixedly connected to the welding table 2, and the first moving part 31 and the second moving part 32 are both slidably connected to the slide rail 33; The horizontal drive component 34 is fixedly connected to the welding table 2; The connecting member 35 is disposed on the moving end of the horizontal drive member 34 and connected to the first moving member 31 and the second moving member 32. The drive assembly 3 is used to convert the power input into the directional movement of the clamping mechanism. The slide rail 33 serves as a motion guide, enabling the first moving member 31 and the second moving member 32 to maintain a stable trajectory during movement, thereby preventing deviations in the clamping position due to motion skew. Figure 3 and Figure 5 As shown, the horizontal drive component 34 is used to output linear power, and the connecting component 35 is used to transmit force between the power source and the moving component, so that the first positioning clamping component 41 and the second positioning clamping component 42 can approach the bracket body 1 according to the preset trajectory.

[0028] In this application, a linear cylinder is specifically used as the horizontal drive component 34. The linear cylinder has a fast response speed, which can meet the needs of frequent reciprocating movements in welding fixtures and is easy to connect to a conventional pneumatic control system. When the linear cylinder retracts, the connecting component 35 is subjected to force and drives the related moving structure to move, so that the first positioning clamping assembly 41 and the second positioning clamping assembly 42 gradually enter the working position; when the linear cylinder extends, the connecting component 35 reverses and resets, so that the clamping area is released again, which facilitates the removal of the bracket body 1 after welding or the insertion of the next set of profile parts.

[0029] In other embodiments of this application, the horizontal drive component 34 may be an electric actuator, a hydraulic cylinder, a servo linear module, or a screw-nut mechanism. Electric actuators are suitable for scenarios requiring electrically controlled start / stop; hydraulic cylinders are suitable for scenarios with larger profiles and higher clamping resistance; servo linear modules are suitable for automated production lines with high requirements for travel distance and speed; and screw-nut mechanisms are suitable for positioning scenarios requiring high self-locking performance. The connecting component 35 ensures that power can be stably transmitted to multiple clamping positions. Through the cooperation of slide rail 33, horizontal drive component 34 and connecting component 35, the tooling can achieve synchronous or related actions of multiple clamping parts with fewer drive sources, reduce the number of independent drive mechanisms, reduce structural complexity, and improve the consistency of pre-welding positioning actions.

[0030] In a preferred embodiment, the present invention may be further configured such that the connecting member 35 includes: The round rod 351 is fixedly connected to the moving end of the horizontal drive member 34, and the first moving member 31 and the second moving member 32 are sleeved on the outside of the round rod 351. At least two positioning parts 352 are fixedly connected to the round rod 351; The first elastic member 353 is connected between the positioning part 352 and the first moving member 31, and / or between the positioning part 352 and the second moving member 32. In this embodiment, the connecting member 35 is used to establish a flexible force transmission relationship between the horizontal driving member 34 and each moving member. Figure 3 and Figure 5 As shown, the round rod 351 serves as the main force transmission base, capable of bearing the push and pull forces output by the horizontal drive component 34; the positioning part 352 is used to define the elastic force transmission position, and the first elastic element 353 is used to provide buffering and stroke compensation during force transmission. Through this structure, the driving force will not act directly on the first bracket 11 or the second bracket 12 in a completely rigid manner, but can be transmitted to the clamping part after elastic buffering.

[0031] In this application, a cylindrical guide rod is used as the rod 351, a fixed collar is used as the positioning part 352, and a compression spring is used as the first elastic element 353. The fixed collar can be fixed to the cylindrical guide rod by set screws, welding, or interference fit. During operation, the horizontal drive member 34 drives the cylindrical guide rod to move, and the fixed collar changes position accordingly, compressing the compression spring. The compression spring then transmits the elastic force to the corresponding moving structure, causing the clamping mechanism to gradually approach the profile part. When the clamping mechanism contacts the profile part or reaches the limit position, the compression spring can continue to generate elastic deformation to absorb excess displacement and impact load, reducing the risk of the profile part being rigidly pushed and shifting.

[0032] In a preferred embodiment, the present invention may be further configured such that the first positioning and clamping assembly 41 includes: At least two mounting parts 411 are slidably connected to the first moving member 31 and are capable of moving relative to the first moving member 31 in a direction perpendicular to the slide rail 33; An elastic adsorption part 412 is disposed on the mounting part 411 and faces the first bracket 11. In this embodiment, the first positioning clamping assembly 41 is mainly used for lateral alignment and holding of the first bracket 11. Figure 5 As shown, the mounting part 411 serves as the supporting base for the elastic adsorption part 412. Driven by the first moving member 31, it approaches the first bracket 11 and undergoes adaptive adjustments under guiding action, allowing the elastic adsorption part 412 to more accurately contact the area to be limited on the first bracket 11. The elastic adsorption part 412 provides flexible adsorption or adhesion after contacting the profile, preventing the rigid grippers from directly colliding with the profile. A groove perpendicular to the slide rail 33 is formed on the surface of the first moving member 31. A slider adapted to the groove is fixedly connected to the surface of the mounting part 411. The slider is slidably connected inside the groove, allowing the mounting part 411 to slide relative to the first moving key 31 through the action of the groove and the slider.

[0033] With at least two mounting parts 411 working in conjunction with the elastic adsorption part 412, the first bracket 11 can be constrained at multiple positions, avoiding deflection of the profile due to single-point force; at the same time, the elastic adsorption part 412 can compensate for slight errors on the surface of the profile, improving the stability and consistency of the pre-welding positioning of the first bracket 11.

[0034] In a preferred embodiment, the present invention may be further configured such that the first positioning and clamping assembly 41 further includes: The slide 413 is formed on the surface of the slide rail 33. The slide 413 includes a first slide section 413a and a second slide section 413b that are interconnected. Pulley 414 is fixedly connected to mounting part 411 and slidably disposed in slide rail 413; The first slide section 413a and the second slide section 413b are sequentially arranged along the extension direction of the slide rail 33, and they have different lateral distances relative to the first bracket 11. This allows the mounting part 411 to move laterally relative to the first moving member 31 via the pulley 414. During the positioning process of the first bracket 11, after the first moving member 31 is displaced, the mounting part 411 does not simply follow in a straight line, but rather forms a composite guiding action under the combined action of the slide rail 413 and the pulley 414. Specifically, when the pulley 414 moves along the slide rail 413, it is constrained by the trajectory of the slide rail 413, causing the mounting part 411 to make lateral adjustments while following the movement of the first moving member 31, thereby causing the elastic adsorption part 412 to move closer to or away from the profile to be positioned. In this way, the unidirectional driving force provided by the drive assembly 3 can be converted into the lateral guiding action required for the positioning of the first bracket 11, avoiding the need for a separate lateral pushing drive source. The effective guiding length of the slide rail 413 can be matched with the working stroke of the horizontal drive member 34.

[0035] like Figure 7 and Figure 9 As shown, when pulley 414 enters the first slide section 413a, the elastic adsorption part 412 gradually approaches the area where the first support 11 or the second support 12 is located, so as to adsorb or contact and limit the profile to be positioned. During this process, it is ensured that even if the second support 12 is not close to the protrusion of the welding table 2 during placement, it can be brought close to the protrusion of the welding table 2 under the drive of slide 413, so as to ensure the accuracy and stability during subsequent welding. Subsequently, as the first moving part 31 continues to move, pulley 414 enters the second slide section 413b. Under the action of trajectory change, the mounting part 411 drives the elastic adsorption part 412 to switch positions, so that the adsorbed or limited profile moves toward the protrusion of the welding table 2, and the first support 11 is limited to the protrusion. Thus, the traction, correction and return of the first support 11 can be realized, so that the first support 11 is gradually adjusted from the initial placement state to the position required for welding.

[0036] In this application, an arc-shaped transition trajectory is specifically used to achieve the motion connection between the first slide section 413a and the second slide section 413b, so that the pulley 414 maintains a continuous rolling state during the position switching process, reducing the impact of sudden motion changes on the positioning accuracy of the first support 11.

[0037] In this application, a needle roller bearing wheel is specifically used as the pulley 414 to reduce rolling resistance during the guiding process and improve load-bearing capacity. In other embodiments of this application, the pulley 414 may be a nylon roller or a metal-coated roller; nylon rollers help reduce operating noise and reduce wear on the slide 413, while metal-coated rollers combine structural strength and cushioning performance.

[0038] From the perspective of the force process, when the pulley 414 moves within the slide rail 413, the track sidewall exerts a constraint force on the pulley 414, which is further converted into a lateral movement force of the mounting part 411. The mounting part 411 drives the elastic adsorption part 412 to act on the first bracket 11, causing the first bracket 11 to gradually approach the predetermined position under the action of adsorption force, pushing force, or traction force. Through the above-mentioned trajectory control method, the positioning action of the first bracket 11 can be automatically completed with the movement of the first moving part 31, improving the repeatability of the positioning action and reducing the impact of manual correction on welding quality.

[0039] In a preferred embodiment, the present invention may be further configured such that the elastic adsorption portion 412 includes: Mounting post 4121 is fixedly connected to mounting part 411; The second elastic element 4122 is disposed on the side of the mounting post 4121 facing the first bracket 11; The magnetic attractor 4123 is connected to the end of the second elastic member 4122 away from the mounting post 4121 and is used for magnetic adsorption engagement with the first bracket 11. The elastic adsorption part 412 is used to form a flexible adsorption effect during the positioning of the first bracket 11. The first bracket 11 is usually a metal profile. When the magnetic attractor 4123 approaches or contacts the first bracket 11, it can generate an adsorption and holding force, causing the first bracket 11 to move under the action of the mounting part 411, thereby realizing the traction and guidance of the first bracket 11. Figure 2 and Figure 8 As shown, the second elastic element 4122 undergoes elastic deformation when the magnetic element 4123 contacts the first bracket 11, so that the magnetic element 4123 will not directly impact the first bracket 11 in a rigid manner. This can reduce the positional displacement of the profile due to instantaneous collision, and at the same time, the magnetic element 4123 can maintain a stable adsorption state under different contact positions.

[0040] In this application, a cylindrical connecting column is used as the mounting column 4121, a compression spring is used as the second elastic element 4122, and a permanent magnet block is used as the magnetic attraction element 4123. During positioning, the permanent magnet block first attracts the first bracket 11, and then the compression spring adapts to the positional error of the first bracket 11, keeping the permanent magnet block stably attached. This method can balance the reliability of attraction and the buffering of contact, and is suitable for the welding positioning of common steel electromechanical pipeline supports.

[0041] In other embodiments of this application, the magnetic attractor 4123 may be an electromagnet, a neodymium iron boron magnet, or a magnetic attractor with detection function. An electromagnet can control adsorption and release by switching on and off electricity, making it suitable for automated production cycles; neodymium iron boron magnets have high magnetic attraction force, making them suitable for non-electrically controlled adsorption scenarios; and a magnetic attractor with detection function can provide feedback on the adsorption position signal, facilitating linkage with a control system.

[0042] By cooperating with the magnetic suction element 4123 and the second elastic element 4122, the elastic suction part 412 can effectively pull the first bracket 11 and compensate for the dimensional error, flatness error or placement error of the profile surface, thereby improving the stability and clamping reliability of the positioning process of the first bracket 11. When no limit is applied, the pulley 414 is at the end of the first slide section 413a. After the horizontal drive element 34 moves to the designated position, the pulley 414 is at the end of the second slide section 413b, at which time the first bracket 11 can be fixed at the first protrusion 21.

[0043] In a preferred embodiment, the present invention may be further configured such that the second positioning and clamping assembly 42 includes: The hinge seat 421 is fixedly connected to the second movable part 32; Flip the fixing plate 422 and hinge it to the hinge seat 421; The lifting plate 423 is slidably connected to the hinge seat 421 and abuts against the flip-fixed plate 422. The supporting member 424 is connected at one end to the lifting plate 423 and at the other end to the positioning part 352 near the second moving member 32. The second positioning and clamping assembly 42 is used to limit the second bracket 12 after it has been placed. In the initial stage of operation, the flipping fixing plate 422 is in a clearance state, allowing the second bracket 12 to smoothly enter the positioning area on the welding table 2, avoiding interference with material feeding due to the limiting member occupying the position prematurely. Figure 5 and Figure 6 As shown, after the second moving part 32 reaches the positioning stage, the support member 424 converts the motion from the drive component 3 into the lifting action of the lifting plate 423. The lifting plate 423 further pushes the flipping fixed plate 422 to rotate, so that the flipping fixed plate 422 switches from the avoidance state to the limit state.

[0044] During this process, the lifting plate 423 undertakes the function of pushing and transmitting force, while the flipping fixing plate 422 undertakes the function of supporting and limiting the second support 12. Since the flipping fixing plate 422 only enters the working position when positioning is required, this structure will not hinder the placement of the second support 12, and can form a constraint in time during the positioning stage, which is conducive to improving the continuity of the feeding and positioning of the second support 12.

[0045] In this application, a plate-shaped support is used as the hinge seat 421, a rectangular pressure plate is used as the flipping fixing plate 422, a vertical guide plate is used as the lifting plate 423, and a universal connection support structure is used as the support member 424. The rectangular pressure plate can increase the contact area with the second bracket 12, making the distribution of the limiting force more stable; the vertical guide plate can ensure a smooth lifting process and prevent the flipping fixing plate 422 from being tilted by force; the universal connection support structure can adapt to the angle changes generated during the operation of the drive component 3.

[0046] In a preferred embodiment, the present invention may be further configured such that the support member 424 includes: The first universal ball joint 4241 is fixedly connected to the positioning part 352 near the second moving part 32; The second universal ball joint 4242 is fixedly connected to the lifting plate 423; The universal ball joint connecting rod 4243 is movably connected at both ends to the first universal ball seat 4241 and the second universal ball seat 4242, respectively. It should be noted that a corresponding limiting mechanism is provided on the slide rail 33. The function of the limiting mechanism is to limit and fix the second moving part 32. That is to say, the second moving part 32 can be fixed in a designated position under the drive of the horizontal drive member 34. The limiting mechanism is a positioning pin (not shown). At this time, the hinge seat 421 corresponds to the position of the second bracket 12. As the horizontal drive member 34 continues to drive, the first elastic member 353 is compressed, thereby further driving the round rod 351 to move. At this time, the positioning part 352 near the second moving part 32 can move.

[0047] The support member 424 is used to convert the horizontal movement of the drive assembly 3 into the lifting movement of the lifting plate 423. For example... Figure 5 and Figure 6 As shown, during operation, the positioning part 352 continues to move with the round rod 351, the first universal ball seat 4241 generates a corresponding displacement, the universal ball connecting rod 4243 changes its posture accordingly, and outputs an oblique force to the second universal ball seat 4242. The vertical component of this oblique force pushes the lifting plate 423 upward, thereby enabling the flipping fixed plate 422 to complete the flipping and limiting action.

[0048] In this application, ball joints are specifically used as the first universal ball joint 4241 and the second universal ball joint 4242, and rigid connecting rods with ball joints at both ends are used as universal ball connecting rods 4243. The ball joint structure allows the universal ball connecting rod 4243 to swing at an angle during force transmission, avoiding jamming due to relative movement between the round rod 351, the second moving part 32 and the lifting plate 423.

[0049] In other embodiments of this application, the universal ball joint connecting rod 4243 may adopt an adjustable length connecting rod, an elastic connecting rod, or a double connecting rod structure. The adjustable length connecting rod can adjust the lifting stroke according to the specifications of the second bracket 12; the elastic connecting rod can absorb part of the impact during the lifting process; the double connecting rod structure can improve the force transmission stability and reduce the off-center load on the lifting plate 423.

[0050] From the perspective of force transmission mechanism, the universal ball connecting rod 4243 converts horizontal displacement into a lifting component force during attitude change, giving the lifting plate 423 an upward tendency. Therefore, the flipping of the rotating fixed plate 422 does not require an additional independent drive source, but is accomplished using the existing motion of the drive component 3, simplifying the power structure and improving the coordination between various positioning actions.

[0051] In a preferred embodiment, the present invention can be further configured such that: the hinge seat 421 and the flip-fixed plate 422 are hinged together by a pin 425; a coil spring 426 is provided on the hinge seat 421, one end of the coil spring 426 is connected to the pin 425, and the other end is connected to the hinge seat 421; the pin 425 provides a stable rotation center for the flip-fixed plate 422, and the coil spring 426 keeps the flip-fixed plate 422 in a reset tendency during the non-positioning stage. Figure 6 As shown, in the initial state, the flip-fixed plate 422 is held in the avoidance position, allowing the second bracket 12 to be placed smoothly. During positioning, the lifting plate 423 moves upward and pushes the flip-fixed plate 422 to rotate. After overcoming the elasticity of the coil spring 426, the flip-fixed plate 422 enters the limit position, thereby supporting the second bracket 12.

[0052] After welding is completed or clamping is released, the lifting plate 423 moves downward, and the coil spring 426 releases its stored elastic potential energy, causing the flipping fixed plate 422 to automatically return to the avoidance position. Through this reset process, the tooling can directly enter the next loading preparation state without the operator having to manually move the flipping fixed plate 422, which helps to improve continuous processing efficiency.

[0053] In this application, a cylindrical pin is used as the pin shaft 425, and a planar spiral spring is used as the coil spring 426. The planar spiral spring stores energy when the flipping fixing plate 422 is lifted, and releases energy after the lifting plate 423 removes the pushing force, so that the flipping fixing plate 422 can automatically reset.

[0054] With the cooperation of pin 425 and coil spring 426, the flipping fixing plate 422 can automatically switch between the avoidance state and the limit state, which not only ensures the placement space of the second bracket 12, but also forms a stable support during the positioning stage, reducing manual intervention and improving the reliability of the positioning action.

[0055] In a preferred embodiment, the present invention can be further configured such that: a first protruding ridge 21 and a second protruding ridge 22 are provided at the edge of the welding table 2, the first protruding ridge 21 abuts against the first support 11, and the second protruding ridge 22 abuts against the second support 12, the first protruding ridge 21 and the second protruding ridge 22 are used to form a fixed positioning reference on the welding table 2. Figure 1 and Figure 3As shown, during the positioning process, the first positioning clamping assembly 41 pulls or pushes the first bracket 11 to the first protruding ridge 21, and the second positioning clamping assembly 42 holds the second bracket 12 against the second protruding ridge 22. Under the combined action of the active clamping force and the reference reaction force, the profile part forms a stable limiting state, thereby reducing the positional deviation before welding.

[0056] In this application, strip-shaped protrusions are specifically used as the first protrusion 21 and the second protrusion 22. The strip-shaped protrusions can provide a continuous abutment reference, so that the first bracket 11 and the second bracket 12 maintain good fit and consistency in the length direction, which is suitable for welding and positioning of long strip profiles.

[0057] In other embodiments of this application, the first protruding ridge 21 and the second protruding ridge 22 may be detachable positioning strips, positioning block assemblies, or adjustable limiting blocks. Detachable positioning strips are easy to replace after wear; positioning block assemblies are suitable for scenarios where the bracket shape has local avoidance requirements; adjustable limiting blocks can adjust the positioning position according to different bracket specifications, improving the tooling versatility.

[0058] During operation, the first support 11 and the second support 12 first enter the positioning area of ​​the welding table 2, and then, under the action of the positioning clamping assembly 4, they move towards their corresponding references. The reference structure provides reverse support to the profile, ensuring that the profile maintains relative positional stability even under welding heat input, welding torch contact, or slight vibration. Thus, the welding table 2 not only bears the load but also participates in forming the final positioning boundary through the first protruding part 21 and the second protruding part 22, improving the consistency of the welding formation of the support body 1.

[0059] During overall operation, the two first supports 11 and the second support 12 are first placed in the positioning area on the welding table 2. Then, the horizontal drive 34 is activated. The horizontal drive 34 drives the first moving part 31 and the second moving part 32 to move along the positioning direction through the connecting member 35, so that the first positioning clamping assembly 41 and the second positioning clamping assembly 42 enter the positioning process synchronously.

[0060] For the first support 11, when the first moving member 31 moves, the mounting part 411 generates a compound displacement under the cooperation of the pulley 414 and the slide rail 413; wherein, when the pulley 414 passes through the first slide rail section 413a, the mounting part 411 drives the elastic adsorption part 412 to move closer to the first support 11, so that the magnetic adsorption member 4123 first adsorbs and holds the first support 11; then the pulley 414 enters the second slide rail section 413b, and the mounting part 411 drives the adsorbed first support 11 to move towards the first protruding part 21 under the guidance of the trajectory, until the first support 11 abuts against the first protruding part 21 and forms a position.

[0061] During this process, the second elastic element 4122 can provide motion compensation and flexible connection during the contact and traction between the magnetic element 4123 and the first support 11, so that the magnetic element 4123 can maintain stable adsorption and avoid rigid collision or excessive pulling that could cause the first support 11 to shift.

[0062] For the second support 12, the second moving member 32 first moves to the designated position under the action of the horizontal driving member 34, and the position is limited by the limiting mechanism. At this time, the hinge seat 421 and the second support 12 are in the corresponding state. After the second moving member 32 is limited, the horizontal driving member 34 continues to move, the first elastic member 353 undergoes compression deformation, so that the round rod 351 can still continue to move relative to the second moving member 32. The positioning part 352 close to the second moving member 32 moves further with the round rod 351, and the supporting member 424 converts the continued displacement into the lifting action of the lifting plate 423. The lifting plate 423 pushes the flipping fixing plate 422 to switch from the avoidance state to the limiting state, thereby holding and fixing the second support 12 against the second protruding part 22.

[0063] Therefore, this fixture utilizes the first elastic element 353 to continue transmitting force after the second moving element 32 is in place, utilizes the first slide section 413a and the second slide section 413b to achieve the first adsorption and then return of the first bracket 11, and uses the second elastic element 4122 to ensure the flexibility and stability of the adsorption and traction process; in the entire positioning process, only one horizontal drive element 34 can simultaneously complete the fixing and limiting of the two first brackets 11 and the second bracket 12, reducing the independent drive mechanism and manual correction steps, and improving the positioning and fixing efficiency before welding.

[0064] This fixture utilizes the slide rail 413 and pulley 414 to achieve the "first adsorption, then traction return" of the first bracket 11. The first elastic element 353 enables the round rod 351 to continue transmitting force after the second moving element 32 is in place. The support member 424 drives the flipping fixing plate 422 to hold the second bracket 12, thereby completing the synchronous positioning and limiting of the two first brackets 11 and the second bracket 12 under the drive of a horizontal driving member 34.
