Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding equipment and method for processing the metal frame of prefabricated houses. Background Technology

[0002] The metal frame of prefabricated houses is usually formed by welding rectangular tubes, square tubes, and other metal frame materials. During processing, one section of metal frame material is first fixedly clamped to a fixed clamp, and then another section of metal frame material is clamped to a movable clamp. The movable clamp moves the metal frame material towards the fixed side, so that the end faces of the two sections of metal frame material are joined together, and then welded by a welding head.

[0003] In existing welding equipment, the movable clamp is often directly driven by the moving seat, which is typically driven by a lead screw mechanism. However, in actual welding processes, it is difficult to guarantee that the movable metal frame material stops precisely at the moment of contact with the fixed metal frame material. Even after the movable metal frame material has made contact with the fixed metal frame material, the moving seat may continue to move forward due to lag in drive response, propulsion inertia, or stroke error, causing the movable metal frame material to continue pressing against the fixed metal frame material, resulting in a hard collision or compression between the end surfaces. For the thin-walled rectangular and square tubes commonly used in the metal frames of prefabricated houses, this collision and compression can easily cause material deformation, affecting the subsequent welding quality. Therefore, we propose a welding equipment and method for processing the metal frames of prefabricated houses. Summary of the Invention

[0018] Connecting ears, which are symmetrically and fixedly connected to the outer wall of the pressure-bearing inclined surface;

[0019] A roller is rotatably connected between the two connecting lugs, and the outer periphery of the roller is used to roll into contact with the pushing inclined surface to reduce the frictional resistance when the wedge push block pushes the locking pressure block.

[0020] Preferably, the unlocking and reset mechanism includes:

[0021] A reset guide groove is formed on the inner wall of the locking receiving groove;

[0022] A reset guide block is fixedly connected to the outer wall of the locking pressure block, and the outer wall of the reset guide block is slidably connected to the inner wall of the reset guide groove.

The top of the clamping seat has a threaded hole, and a screw is threadedly connected to the inner wall of the threaded hole. A throttle is fixedly connected to the top of the screw. The bottom of the clamping seat has a bottom groove, and a pressure block is movably arranged inside the bottom groove. The bottom of the screw is rotatably connected to the top of the pressure block.

[0026] Preferably, a sliding buffer mechanism is provided between the floating clamping seat and the push slide, the sliding buffer mechanism comprising:

[0027] A guide groove is formed at the top of the pusher slide;

[0028] A guide slider is fixedly connected to the bottom end of the floating clamping seat, and the outer wall of the guide slider is slidably connected to the inner wall of the guide groove.

[0035] The technical effects and advantages of this invention are as follows:

[0036] This invention moves a floating clamping seat by pushing a slide. When the material on the floating clamping seat comes into contact with the material on the fixed clamping seat, the slide continues to move while the floating clamping seat remains stationary relative to the fixed clamping seat. The relative movement between the slide and the floating clamping seat triggers a locking mechanism, which fixes the sliding clamping seat to the worktable. This allows the material on the moving side to be restricted in time at the actual contact position, preventing it from continuing to rigidly move forward with the slide and causing hard collisions or compression to the metal frame material on the fixed side.

Detailed Implementation

[0046] 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.

[0047] This invention provides, for example Figures 1-7 The welding equipment for processing the metal frame of the integrated house shown includes a workbench 101, a fixed clamping seat 102 fixedly disposed on the top of the workbench 101, a floating clamping seat 103 movably disposed on the top of the workbench 101, and a welding head 104 disposed above the workbench 101. It also includes a push slide 201, a linkage locking seat 202, and a fixed locking plate 203.

[0048] The push slide 201 is slidably connected to the top of the worktable 101. The floating clamping seat 103 moves with the push slide 201 toward the fixed clamping seat 102, and slides relative to the push slide 201 after the metal frame material it holds comes into contact with the metal frame material held by the fixed clamping seat 102. In specific use, the fixed clamping seat 102 is used to clamp a section of metal frame material at a reference position, and the floating clamping seat 103 is used to clamp another section of metal frame material to be moved and docked. The push slide 201 can move along the worktable 101 under the drive of a screw moving structure, cylinder, or other linear drive structure, thereby driving the floating clamping seat 103 and its clamped part. The metal frame material is held close to the fixed clamping seat 102. Since the floating clamping seat 103 is not rigidly fixed to the push slide 201, when the end faces of the two metal frame materials come into contact, the floating clamping seat 103 can slide relative to the push slide 201 due to the end face contact, thereby avoiding the rigid forward thrust at the moment of contact. In other words, this embodiment does not rely on the absolute stop of the push slide 201 at the preset position to achieve docking, but allows the floating clamping seat 103 to make room at the actual contact position, thereby converting the impact tendency of the end faces of the two metal frame materials at the moment of contact into the relative displacement between the push slide 201 and the floating clamping seat 103.

[0049] A fixed locking plate 203 is fixedly connected to the top of the worktable 101, and a linkage locking seat 202 is fixedly connected to the bottom of the floating clamping seat 103. A locking mechanism is provided between the linkage locking seat 202 and the fixed locking plate 203. A triggering mechanism is provided between the push slide 201 and the locking mechanism. The triggering mechanism is used to trigger the locking mechanism when the push slide 201 continues to move relative to the floating clamping seat 103, thereby fixing the floating clamping seat 103 to the worktable 101. When the metal frame material on the floating clamping seat 103 has contacted the metal frame material on the fixed clamping seat 102, the subsequent movement of the push slide 201... The continued movement caused by driving inertia, control lag, or stroke error will not be directly converted into extrusion force on the end faces of the two metal frame materials. Instead, it will first form a relative sliding between the push slide 201 and the floating clamp 103, and use this relative sliding to trigger the locking mechanism to fix the floating clamp 103 at the actual contact position of the two metal frame materials. This forms a continuous mechanical response process of end face contact - relative clearance - automatic locking, so that the floating clamp 103 can be restricted in time after the end face of the materials is just completed, and avoid the floating clamp 103 continuing to move forward with the push slide 201 and causing secondary pressure.

[0050] A sliding buffer mechanism is provided between the floating clamping seat 103 and the push slide 201. The sliding buffer mechanism includes a guide groove 301, a guide slider 302, and a first compression spring 303. The guide groove 301 is located at the top of the push slide 201, and the guide slider 302 is fixedly connected to the bottom of the floating clamping seat 103. The outer wall of the guide slider 302 is slidably connected to the inner wall of the guide groove 301. The first compression spring 303 is disposed between the guide slider 302 and the inner wall of the guide groove 301, and is used to be compressed when the push slide 201 continues to move relative to the floating clamping seat 103, so as to absorb the pressure of the push slide 201. The remaining pushing displacement; before the two metal frame materials come into contact, the first compression spring 303 can keep the guide slider 302 in the initial position in the guide groove 301, so that the floating clamping seat 103 can move stably with the pushing slide 201; when the end faces of the two metal frame materials come into contact, the floating clamping seat 103 stops due to the reaction force of the fixed side material. When the pushing slide 201 continues to move, the guide groove 301 moves relative to the guide slider 302 and compresses the first compression spring 303, thereby converting the remaining pushing displacement of the pushing slide 201 into elastic compression displacement, reducing the hard collision between the end faces of the two metal frame materials.

[0051] The guide groove 301 has a first guide rod 304 fixedly connected to its inner wall, and a guide slider 302 has a first guide hole 305. The first guide rod 304 is inserted into the inner wall of the first guide hole 305, and a first compression spring 303 is sleeved on the outer wall of the first guide rod 304. The first guide rod 304 cooperates with the first guide hole 305 to restrict the sliding direction of the guide slider 302 in the guide groove 301, and prevent the floating clamp 103 from swaying during relative sliding. At the same time, the first compression spring 303 sleeved on the outer wall of the first guide rod 304 can improve the stability of the spring compression process and prevent the first compression spring 303 from bending and shifting after being compressed. This ensures that the floating clamp 103 still moves along the docking direction of the metal frame material during the yielding process, and will not introduce lateral offset due to buffering, thereby ensuring the stability of the docking position of the two metal frame materials.

[0052] The locking mechanism includes a locking receiving groove 401, a locking pressure block 402, and an unlocking and resetting mechanism. The locking receiving groove 401 is located on the side of the linkage locking seat 202 facing the fixed locking plate 203. The locking pressure block 402 is slidably connected to the inner wall of the locking receiving groove 401, and the side of the locking pressure block 402 facing the fixed locking plate 203 is used to press against the fixed locking plate 203. The unlocking and resetting mechanism is located between the locking pressure block 402 and the locking receiving groove 401, and is used to move the locking pressure block 402 away from the fixed locking plate 203 after the triggering mechanism releases the pressure. 03 Reset, the locking receiving groove 401 provides lateral movement space for the locking block 402, so that the locking block 402 can remain separated from the fixed locking plate 203 in the non-triggered state, ensuring that the floating clamping seat 103 can move normally; when the triggering mechanism pushes the locking block 402 toward the fixed locking plate 203, the locking block 402 presses against the fixed locking plate 203, thereby fixing the floating clamping seat 103 to the worktable 101 through the linkage locking seat 202, preventing the floating clamping seat 103 from continuing to move toward the fixed clamping seat 102.

[0053] The triggering mechanism includes a wedge block 403, a pushing ramp 404, a pressure-receiving ramp 405, and a clearance opening 406. The wedge block 403 is symmetrically fixed to both sides of the push slide 201 and can move with the push slide 201 relative to the linkage locking seat 202. The pushing ramp 404 is formed on the outer wall of the wedge block 403, and the pressure-receiving ramp 405 is formed on the side of the locking block 402 away from the fixed locking plate 203. The pushing ramp 404 and the pressure-receiving ramp 405 are correspondingly arranged. The clearance opening 406 is formed on the outer wall of the linkage locking seat 202 and communicates with the locking receiving groove 401. The wedge block 403 is inserted into the clearance opening 406. When the floating clamping seat 103 moves synchronously with the push slide 201, the wedge block 403 and the linkage locking seat 202 remain basically stationary relative to each other, and the locking block 402 does not move relative to the fixed locking plate. 203 generates a locking effect; when the two metal frame materials come into contact, the floating clamping seat 103 and the linkage locking seat 202 remain stationary relative to the fixed clamping seat 102, while the push slide 201 continues to move, causing the wedge push block 403 to advance along the clearance opening 406 relative to the linkage locking seat 202. The pushing slope 404 then squeezes the pressure slope 405, converting the axial continued movement of the push slide 201 into a lateral pressing action of the locking pressure block 402 toward the fixed locking plate 203. Through this slope conversion structure, the remaining forward stroke of the push slide 201 is no longer manifested as continued pressing on the end face of the metal frame material, but is converted into a locking force on the floating clamping seat 103, forming a functional transfer of the remaining pushing energy. This structure makes the inevitable continued movement a triggering force for the locking action, thereby improving the coordination of the structural actions.

[0054] The outer wall of the pressure-bearing inclined surface 405 is provided with rolling force transmission components at intervals. The rolling force transmission components include connecting ears 407 and rollers 408. The connecting ears 407 are symmetrically fixed to the outer wall of the pressure-bearing inclined surface 405, and the rollers 408 are rotatably connected between the two connecting ears 407. The outer circumference of the rollers 408 is used to roll contact with the pushing inclined surface 404 to reduce the frictional resistance when the wedge push block 403 pushes the locking block 402. By setting the rollers 408, the sliding friction between the pushing inclined surface 404 and the pressure-bearing inclined surface 405 is transformed into rolling contact. This enables the wedge push block 403 to push the locking block 402 to move with a smaller relative movement resistance, avoiding the locking mechanism from being insensitive due to excessive friction on the inclined surface. This improves the locking timeliness of the floating clamping seat 103 after contact with the material end face.

[0055] The unlocking and resetting mechanism includes a reset guide groove 501, a reset guide block 502, and a second compression spring 503. The reset guide groove 501 is formed on the inner wall of the locking receiving groove 401. The reset guide block 502 is fixedly connected to the outer wall of the locking pressure block 402, and the outer wall of the reset guide block 502 is slidably connected to the inner wall of the reset guide groove 501. The second compression spring 503 is disposed between the reset guide block 502 and the inner wall of the reset guide groove 501, and is used to push the locking pressure block 402 away from the fixed locking plate 203 to reset. After welding is completed, the mechanism is pushed forward. As the slide block 201 moves in the opposite direction, the wedge push block 403 gradually releases its pressure on the locking block 402. The second compression spring 503 pushes the locking block 402 away from the fixed locking plate 203 through the reset guide block 502, thereby releasing the floating clamping seat 103 from the locking state between it and the worktable 101, facilitating the next clamping and docking. Thus, the locking mechanism can provide stable fixation during the docking and welding stage and automatically return to a movable state after welding is completed, reducing manual disassembly or manual reset steps and improving the operating efficiency during continuous processing.

[0056] The inner wall of the reset guide groove 501 is fixedly connected to a second guide rod 504, and the outer wall of the reset guide block 502 is provided with a second guide hole 505. The second guide rod 504 is inserted into the inner wall of the second guide hole 505, and the second compression spring 503 is sleeved on the outer wall of the second guide rod 504. The second guide rod 504 cooperates with the second guide hole 505 to limit the reset direction of the locking block 402, so that the locking block 402 can slide stably along the locking receiving groove 401. The second compression spring 503 is sleeved on the outer wall of the second guide rod 504, which can improve the smoothness of the reset action and prevent the second compression spring 503 from deflecting during compression or release.

[0057] A clamping seat 601 is symmetrically fixedly connected to the outer wall of the floating clamping seat 103 and above the fixed locking plate 203. The top of the clamping seat 601 has a threaded hole 602, and a screw 603 is threadedly connected to the inner wall of the threaded hole 602. A handle 604 is fixedly connected to the top of the screw 603. A bottom groove 605 is formed at the bottom end of the clamping seat 601, and a pressure block 606 is movably disposed inside the bottom groove 605. The bottom end of the screw 603 is rotatably connected to the top end of the pressure block 606. After the locking mechanism completes locking, rotating the handle 604 can drive the screw 603 to move downwards along the threaded hole 602, causing the pressure block 606 to press against the fixed locking plate 203, thereby providing auxiliary clamping for the floating clamping seat 103. This auxiliary clamping structure can further improve the positional stability of the floating clamping seat 103 during welding and reduce the impact of welding vibration or external force interference on the joint position of the two metal frame materials.

[0058] A welding method for a welding equipment used in the fabrication of metal frames for prefabricated houses, comprising:

[0059] The drive slide 201 moves along the worktable 101 toward the fixed clamping seat 102, causing the drive slide 201 to bring the floating clamping seat 103 and the metal frame material it clamps closer to the metal frame material on the fixed clamping seat 102; during this stage, the floating clamping seat 103 is held in the initial position on the drive slide 201 under the action of the first compression spring 303, and the metal frame material can smoothly approach the fixed side material with the drive slide 201;

[0060] When the end faces of the two metal frame materials come into contact, the floating clamp 103 remains stationary relative to the fixed clamp 102, and the push slide 201 continues to move and slides relative to the floating clamp 103. During this stage, the metal frame materials after contact no longer continue to rigidly advance with the push slide 201, but the remaining pushing displacement of the push slide 201 is isolated from the end faces of the metal frame materials by the sliding of the floating clamp 103 relative to the push slide 201.

[0061] The relative sliding of the wedge pusher 403 pushes the locking block 402 to press against the fixed locking plate 203, thereby fixing the floating clamp seat 103 on the worktable 101. The welding head 104 is used to weld the joint position of the two metal frame materials. In this process, the relative sliding between the push slide 201 and the floating clamp seat 103 is not only used to absorb the remaining push displacement, but also serves as the action source for triggering the locking mechanism, so that the floating clamp seat 103 can automatically lock at the actual contact position of the two metal frame materials. This ensures the end face is joined while reducing the material deformation caused by collision and squeezing, and improves the positioning stability before welding and the subsequent welding quality.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
