Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figure 1 - Figure 5 The present invention relates to a welding fixture for a profile frame, comprising a base 1 and several fixed platforms 2 and a rotating platform 3 slidably mounted on the base 1. Several sliding grooves 11 are provided through one side of the base 1. Each fixed platform 2 and rotating platform 3 is provided with a sliding block 4 that mates with the sliding groove 11. Each fixed platform 2 and rotating platform 3 is provided with a fixed plate 5 and a sliding plate 6, respectively located at both ends of the fixed platform 2 and rotating platform 3. Each fixed platform 2 and rotating platform 3 is provided with a driving component 7 that mates with the sliding plate 6. One end of the sliding block 4 is provided with a sliding rod. Each fixed platform 2 and rotating platform 3 is provided with a sliding nut that mates with the sliding rod. By rotating and adjusting the sliding nut and sliding rod, the sliding block 4 mates with the sliding groove 11, thereby achieving the fixing and sliding of the fixed platform 2 and rotating platform 3. The sliding plate 6 is located at the output end of the driving component 7. Under the action of the driving component 7, the sliding plate 6 moves along the fixed platform 2 or rotating platform 3, thereby mates with the fixed plate 5 to firmly clamp the profile.

[0023] During use, the fixed platform 2 and the rotating platform 3 are loosened by tightening the sliding nut, and their positions and angles are adjusted according to the frame shape to meet welding requirements. After adjustment, the fixed platform 2 and the rotating platform 3 are fixed by tightening the sliding nut, thus preventing displacement during welding and ensuring welding accuracy and stability. The profile is then placed in the fixture, and the sliding plate 6 is pushed by the drive component 7, causing the profile to be tightly clamped by the sliding plate 6 and the fixed plate 5, ensuring the profile remains stable during welding and preventing deformation.

[0024] The rotary table 3 includes a base plate 31, a rotating shaft 32, and a rotating plate 33. The rotating shaft 32 is located on the upper end of the base plate 31, and the rotating plate 33 is rotatably mounted on the upper end of the rotating shaft 32 via a bearing seat 34. A bearing that mates with the rotating shaft 32 is installed inside the bearing seat 34. The rotating plate 33 is fixedly mounted on the bearing seat 34 by bolts and rotates as the bearing seat 34 rotates. An angle disc is provided at one end of the rotating shaft, and a pointer that mates with the angle disc is provided on the rotating plate 33. The angle disc is engraved with precise angle graduations. By matching the pointer with the angle graduations, the angle of the rotating plate 33 can be precisely adjusted to ensure the accuracy of the welding position.

[0025] An angle limiting groove 311 is provided through one end of the base plate 31, and the bearing seat 34 is provided with a limiting rod 341 that cooperates with the angle limiting groove 311. A limiting nut is provided at one end of the limiting rod 341. By rotating the limiting nut, one end of the limiting rod 341 is pressed against or released from the angle limiting groove 311, thereby precisely controlling the rotation angle of the rotating plate 33. Through the cooperation of the angle limiting groove 311 and the limiting rod 341, the maximum rotation range of the rotating plate 33 is limited, ensuring that it operates within a safe range. In this embodiment, the maximum rotation angle of the rotating plate 33 is 180 degrees. The rotating plate 33 can be flexibly adjusted within the range of 0 to 180 degrees to meet the requirements of different welding angles.

[0026] The sliding groove 11 is a T-shaped groove or a dovetail groove. Correspondingly, the sliding block 4 is also T-shaped or dovetail-shaped, thereby ensuring a tight fit between the sliding block 4 and the sliding groove 11, enhancing the stability and guiding properties of the sliding block 4, ensuring no shaking during sliding, and preventing the sliding block 4 from falling off, thus affecting the welding quality. In this embodiment, a combination design of a T-shaped groove and a T-shaped sliding block 4 is adopted to ensure that the sliding block 4 moves smoothly within the groove.

[0027] Both the fixed plate 5 and the sliding plate 6 have a detachable clamping plate 8 at one end. A quick-release block 81 is provided on one side of the clamping plate 8, with a quick-release groove 811 extending through one end of the quick-release block 81. Both the fixed plate 5 and the sliding plate 6 have quick-release pins 82 that engage with the quick-release groove 811. The quick-release block 81 is fixed to the clamping plate 8 with bolts. One end of the quick-release groove 811 has a through hole for inserting the quick-release pin 82. In use, align the through hole with the quick-release pin 82 and insert it, then press down on the clamping plate 8 to engage the quick-release pin 82 into the quick-release groove 811, achieving quick fixation of the clamping plate 8. For disassembly, simply lift the clamping plate 8 upwards, aligning the quick-release pin 82 with the through hole, disengaging the quick-release pin 82 from the quick-release groove 811, and the clamping plate 8 can be easily removed, greatly improving operational efficiency.

[0028] The clamping plate 8 can be replaced according to the shape of the profile to ensure a tight fit between the clamping plate 8 and the profile, avoiding welding errors caused by gaps. In this embodiment, a triangular clamping plate 8 is used to accommodate the fixing requirements of cylindrical profiles.

[0029] Both the fixed platform 2 and the rotary platform 3 have a support plate 9 at one end for mounting the driving component 7. Guide posts 91 that connect and cooperate with the sliding plate 6 are provided on both sides of the support plate 9. A return spring 92 is sleeved on the outer side of the guide post 91, with its two ends abutting against the guide post 91 and the support plate 9, respectively. The support plate 9 is fixed to the rotary platform 3 and the fixed platform 2 by bolts, and the driving component 7 is installed in the center of the support plate 9. Guide holes that cooperate with the guide posts 91 are provided on both sides of the support plate 9. The cooperation between the guide posts 91 and the guide holes ensures the stability of the sliding plate 6 during movement, thereby improving welding accuracy. The function of the return spring 92 is to ensure that the sliding plate 6 automatically returns to its original position when not in operation, thus avoiding affecting the next operation.

[0030] The driving component 7 can be an electric push rod or a cylinder, etc. Through the extension and retraction of the driving component 7, the sliding plate 6 moves smoothly along the guide post 91, achieving precise welding position adjustment. The selection of the driving component 7 needs to be determined according to the specific application scenario and load requirements to ensure the reliability and stability of the welding fixture. In this embodiment, a cylinder is used as the driving component. The cylinder precisely controls the movement of the sliding plate 6 through the extension and retraction of the piston rod. When the cylinder piston rod extends, the sliding plate 6 moves forward, pushing the profile tightly against the fixed plate 5 to achieve the clamping function and ensure the stability of the profile during welding. When the cylinder piston rod retracts, the return spring 92 works together with the cylinder piston rod to quickly return the sliding plate 6 to its original position, thereby completing the release operation, ensuring the rapid release of the profile and improving overall work efficiency.

[0031] The beneficial effects of this utility model are as follows: The sliding groove 11 and the sliding block 4 cooperate to achieve flexible movement and fixation of the fixed platform 2 and the rotating platform 3. The position, angle, and number of the fixed platform 2 and the rotating platform 3 can be adjusted according to the frame shape to meet welding requirements. Then, through the cooperation of the fixed plate 5, the sliding plate 6, and the driving component 7, the profile is firmly fixed in the required position, thereby ensuring welding accuracy and stability.
