[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily-use metal products, etc. With social progress and technological development, metal products are being used more and more widely in various fields of industry, agriculture and people's lives, creating greater and greater value for society.

[0003] Existing positioning fixtures cannot quickly adjust the angle and height of metal products after clamping them, which cannot meet daily usage needs. Therefore, this invention proposes a positioning fixture for metal welding to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide a positioning fixture for metal welding, so as to solve the problem in the background art that the positioning fixture cannot quickly adjust the angle and height of the metal product after clamping it, thus failing to meet the needs of daily use.

[0005] To achieve the above objectives, this application provides the following technical solution: a positioning fixture for metal welding, comprising a base, a sliding sleeve fixedly mounted on the top of the base, a support rod slidably connected to the inner wall of the sliding sleeve, a turntable fixedly mounted on the top of the support rod, and a mounting plate rotatably connected to the top of the turntable. The top of the mounting plate is provided with symmetrically arranged clamping mechanisms, and there are two sets of clamping mechanisms. The bottom of the mounting plate is provided with symmetrically arranged positioning mechanisms and control mechanisms. The top of the base is provided with symmetrically arranged support mechanisms, and there are two sets of both support mechanisms and positioning mechanisms. The control mechanisms cooperate with the positioning mechanisms and support mechanisms respectively.

[0006] With the above structure, by setting up a clamping mechanism and a positioning control mechanism in coordination, the metal workpiece can be adjusted with multiple degrees of freedom under the coordinated support of the base and the turntable. The support rod can be height adjusted, and the turntable provides a horizontal rotation function, so that the workpiece can be quickly positioned to the optimal welding angle to meet the welding needs of different positions.

[0007] Preferably, the clamping mechanism includes: a sliding plate, an electric push rod, a placement plate, a clamp, a threaded rod, and a threaded block; The sliding plate is slidably connected to the top of the mounting plate, the electric push rod is fixedly installed on the top of the mounting plate, the output shaft of the electric push rod is fixedly connected to the sliding plate, the placement plate is fixedly installed on the top of the sliding plate, the clamp is slidably connected to the sliding plate, the threaded rod is rotatably connected to the top of the clamp, the outer side of the threaded rod is threadedly connected to the inner side of the threaded block, and the threaded block is fixedly connected to the sliding plate.

[0008] Furthermore, the clamping mechanism uses an electric push rod to drive the sliding plate to achieve rapid opening and closing, combined with a threaded rod for fine-tuning and locking. This not only adapts to clamping workpieces of different sizes, but also ensures stable clamping force during welding, improving clamping efficiency and accuracy.

[0009] Preferably, the positioning mechanism includes: a positioning frame, a return spring, and a fixing block; The positioning frame is slidably connected to the turntable, the positioning frame is fixedly connected to the return spring, the return spring is fixedly connected to the fixing block, and the fixing block is fixedly connected to the turntable.

[0010] Furthermore, the positioning mechanism uses a reset spring to push the positioning frame to automatically engage in the positioning slot, thereby quickly locking the turntable angle and preventing rotation during welding. The fixing block ensures the stability of the spring force, achieving reliable angle positioning.

[0011] Preferably, the support mechanism includes: a tension spring, a support frame, and a fixing plate; The fixing plate is fixedly installed on the top of the base, the support frame is slidably connected to the bottom of the turntable, and the tension spring is fixedly connected to the support frame and the support rod respectively.

[0012] Furthermore, the support mechanism utilizes tension springs to provide continuous support force, forming a stable fulcrum through the cooperation of the support frame and the fixed plate, preventing the turntable from sinking and ensuring the positional stability after height adjustment.

[0013] Preferably, the control mechanism includes: a connecting frame, a lever, and a pull rod; The connecting frame is fixedly installed at the bottom of the two positioning frames. The two pull rods are rotatably connected to the connecting frame and the two support frames respectively. The two levers are rotatably connected to the front side of the connecting frame, and the top of the levers slides in contact with the bottom of the turntable.

[0014] Furthermore, the control mechanism synchronously controls the positioning and support mechanisms on both sides through the connecting frame. The linkage design of the lever and the pull rod realizes the coordinated operation of angle locking and height support. After rotating the lever, the lever can push the connecting frame and the two positioning frames downward to unlock the turntable. Then, pulling the two pull rods can pull the two support frames to detach from the fixed plate, thereby realizing the adjustment of the turntable height and simplifying the adjustment process.

[0015] Preferably, a positioning block is fixedly installed on the top of the positioning frame, and multiple positioning grooves are evenly spaced on the bottom of the turntable, with the outer side of the positioning block slidingly contacting the inner wall of the positioning groove.

[0016] Furthermore, the precise fit between the equally spaced positioning slots and the positioning blocks provides multiple angle options to meet common welding angle requirements and ensure positioning repeatability accuracy.

[0017] Preferably, a support block is fixedly installed on the support frame, and a plurality of support grooves are provided on the fixed plate at equal intervals, with the outer side of the support block slidingly contacting the inner wall of the support groove.

[0018] Furthermore, the stepped cooperation between the support groove and the support block forms a height locking mechanism, providing multiple stable support positions to adapt to different welding height requirements.

[0019] Preferably, the top of the mounting plate is provided with a horizontal sliding groove, and the bottoms of the two sliding plates are slidably connected to the inner wall of the horizontal sliding groove.

[0020] Furthermore, the horizontal slide ensures that the two sliding plates move synchronously and symmetrically, keeping the center position of the workpiece unchanged and improving the clamping symmetry and stability.

[0021] The beneficial effects of this invention are: 1. The clamping mechanism uses an electric push rod to drive the sliding plate to achieve rapid opening and closing, and combines it with a threaded rod for fine-tuning and locking. It can adapt to the clamping of workpieces of different sizes, and ensure that the clamping force is maintained during the welding process, thereby improving clamping efficiency and accuracy. 2. The positioning mechanism uses a reset spring to push the positioning frame into the positioning slot automatically, forming a quick lock on the turntable angle to prevent rotation during welding. The fixed block ensures the stability of the spring force, achieving reliable angle positioning. 3. The support mechanism uses tension springs to provide continuous support force, and forms a stable fulcrum through the cooperation of the support frame and the fixed plate to prevent the turntable from sinking and ensure the positional stability after height adjustment; 4. The control mechanism synchronously controls the positioning and support mechanisms on both sides through the connecting frame. The linkage design of the lever and the pull rod realizes the coordinated operation of angle locking and height support. After rotating the lever, the lever can push the connecting frame and the two positioning frames downward to unlock the turntable. Then, pull the two pull rods, which can pull the two support frames to separate from the fixed plate, thereby realizing the adjustment of the turntable height and simplifying the adjustment process. This invention achieves multi-degree-of-freedom adjustment of metal workpieces by setting up a clamping mechanism and a positioning control mechanism in conjunction with the base and turntable for coordinated support. The support rod can be height adjusted, and the turntable provides a horizontal rotation function, enabling the workpiece to be quickly positioned to the optimal welding angle and meeting the welding needs of different positions.

The positioning mechanism pushes the positioning frame 12 to automatically engage in the positioning groove through the return spring 14, forming a quick angle lock of the turntable 4 to prevent rotation during welding. The fixing block 15 ensures the stability of the spring force and achieves reliable angle positioning.

[0029] In this embodiment, the support mechanism includes: a tension spring 19, a support frame 20, and a fixing plate 21; The fixed plate 21 is fixedly installed on the top of the base 1, the support frame 20 is slidably connected to the bottom of the turntable 4, and the tension spring 19 is fixedly connected to the support frame 20 and the support rod 3 respectively. The support mechanism uses the tension spring 19 to provide continuous support force. The support frame 20 and the fixed plate 21 cooperate to form a stable fulcrum, prevent the turntable 4 from sinking, and ensure the positional stability after height adjustment.

[0030] In this embodiment, the control mechanism includes: a connecting frame 16, a lever 17, and a pulling rod 18; The connecting frame 16 is fixedly installed at the bottom of the two positioning frames 12.

The two levers 17 are rotatably connected to the front side of the connecting frame 16. The top of the lever 17 slides in contact with the bottom of the turntable 4. The control mechanism controls the positioning and support mechanisms on both sides synchronously through the connecting frame 16. The linkage design of the lever 17 and the pull rod 18 realizes the coordinated operation of angle locking and height support. After rotating the lever 17, the lever 17 can push the connecting frame 16 and the two positioning frames 12 downward to unlock the turntable 4. Then, by pulling the two pull rods 18, the two pull rods 18 can pull the two support frames 20 to disengage from the fixed plate 21, thereby realizing the adjustment of the height of the turntable 4 and simplifying the adjustment process.

The horizontal slide groove ensures that the two sliding plates 6 move synchronously and symmetrically, keeping the center position of the workpiece unchanged and improving the clamping symmetry and stability.

Rotating the lever 17 pushes the connecting frame 16 and the two positioning frames 12 downwards, unlocking the turntable 4. Pulling the two pull rods 18 then disengages the two support frames 20 from the fixed plate 21, allowing for height adjustment of the turntable 4 and simplifying the adjustment process. With the coordinated support of the base 1 and the turntable 4, multi-degree-of-freedom adjustment of the metal workpiece is achieved. The support rod 3 allows for height adjustment, and the turntable 4 provides horizontal rotation functionality, allowing the workpiece to... It can quickly locate the optimal welding angle to meet the welding needs of different positions. The clamping mechanism uses an electric push rod 7 to drive the sliding plate 6 to achieve rapid opening and closing, and combines with the threaded rod 10 for fine adjustment and locking. It can adapt to the clamping of workpieces of different sizes and ensure that the clamping force is maintained during the welding process, improving clamping efficiency and accuracy. The positioning mechanism pushes the positioning frame 12 to automatically lock into the positioning groove through the return spring 14, forming a quick locking of the turntable 4 angle to prevent rotation during welding. The fixing block 15 ensures the stability of the spring force and achieves reliable angle positioning. The support mechanism uses the tension spring 19 to provide continuous support force. The cooperation between the support frame 20 and the fixing plate 21 forms a stable fulcrum to prevent the turntable 4 from sinking and ensure the positional stability after height adjustment.
