[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-6A welding fixture for a compressor bracket assembly includes a fixed base 1, which serves as the basic support structure for the entire fixture. The fixed base 1 provides a sliding track and support for the horizontal rotating base 2, ensuring the stability of the entire fixture during operation. Its stability is a prerequisite for the normal operation of subsequent structural components. The horizontally curved recessed design at the top of the fixed base 1 allows for the lateral rotation of the horizontal rotating base 2, enabling the fixture to adjust the angle of the workpiece in the horizontal direction. The horizontal rotating base 2 is slidably connected to the top of the fixed base 1. The horizontal rotating base 2 slides on the top of the fixed base 1, achieving lateral rotation. This causes the vertical rotating base 3, the self-rotating base 4, and the workpiece to adjust their angles in the horizontal direction, increasing the horizontal adjustment function of the fixture and facilitating welding. The horizontal angle of the workpiece can be flexibly adjusted according to actual needs, improving the adaptability of the tooling to different welding scenarios. A vertical rotating base 3 is slidably connected to the top of the horizontal rotating base 2. The vertical rotating base 3 slides on top of the horizontal rotating base 2, achieving vertical rotation, which further drives the self-rotating base 4 and the workpiece to adjust their angle in the vertical direction. In conjunction with the horizontal rotating base 2, it realizes the vertical angle adjustment of the tooling, allowing the workpiece to be adjusted in more dimensions to meet the needs of complex welding angles. A self-rotating base 4 is rotatably connected to the top of the vertical rotating base 3. The self-rotating base 4 rotates relative to the top of the vertical rotating base 3, allowing for the rotation adjustment of the workpiece, providing a more precise angle adjustment method. Combined with the adjustment of the horizontal rotating base 2 and the vertical rotating base 3, it enables the workpiece to achieve… To achieve a more precise welding position and improve welding accuracy, the outer wall of the rotating base 4 is threaded with a threaded bolt 15. A torsion block 16 is fixedly connected to the top of the threaded bolt 15. Rotating the torsion block 16 causes the threaded bolt 15 to rotate, making the bottom end of the threaded bolt 15 tightly contact the top of the vertical rotating base 3, thus locking the angle of the rotating base 4. A clamping device is fixedly connected to the top of the rotating base 4. This clamping device is used to clamp the compressor bracket assembly to be welded, ensuring that the workpiece will not move arbitrarily during the welding process, guaranteeing the stability of the workpiece during welding. This is one of the key structures for achieving accurate welding, avoiding a decrease in welding quality due to workpiece shaking. This is existing technology. Limiting plates are fixedly connected to the front and rear sides of the fixed base 1 and the left and right sides of the horizontal rotating base 2. 5. A limiting groove 6 is formed on the outer wall of the limiting plate 5. The limiting plate 5 and the limiting groove 6 provide a basis for positioning and adjustment of the adjusting rod 7 and the positioning mechanism, limiting the sliding range of the horizontal rotating base 2 and the vertical rotating base 3, ensuring the stability and accuracy of the horizontal rotating base 2 and the vertical rotating base 3 during the sliding process, avoiding excessive sliding that could cause damage to the tooling structure or workpiece position deviation, and improving the reliability and service life of the tooling. Adjusting rods 7 are fixedly connected to the front and rear sides of the horizontal rotating base 2 and the left and right sides of the vertical rotating base 3. One end of the adjusting rod 7 is fixedly connected to an adjusting plate 8. The adjusting rod 7 is used to connect the positioning mechanism and the limiting groove 6. The angle of the horizontal rotating base 2 and the vertical rotating base 3 can be adjusted by operating the adjusting rod 7, providing operators with a convenient means of adjustment.This design allows for flexible adjustment of the workpiece angle during welding, improving the tooling's operability. The adjusting rod 7 is connected to the limiting groove 6 via a positioning mechanism. The fixed base 1 has a horizontally curved groove at the top, which is fully fitted with the bottom of the horizontally rotating base 2, enabling horizontal rotation adjustment. The horizontally rotating base 2 has a vertically curved groove at the top, which is fitted with the bottom of the vertically rotating base 3, allowing for vertical rotation adjustment. The rotating base 4 can rotate relative to the top of the vertically rotating base 3. This allows the tooling to adjust the workpiece angle in multiple dimensions, meeting the welding requirements of various complex angles. This significantly improves the tooling's adaptability to different welding scenarios. Compared to traditional tooling, it significantly reduces welding difficulties caused by inconvenient angle adjustment, thus improving welding efficiency.

[0021] Please see Figure 4-6 The positioning mechanism includes a positioning block 9, which can be fully retracted into the adjusting rod 7. A telescopic block 10 is slidably connected to the inner wall of the adjusting rod 7, and the outer wall of the telescopic block 10 is rotatably connected to the outer wall of the positioning block 9. The positioning block 9 passes through the adjusting rod 7 and can slide relative to it. A limiting block 11 is fixedly connected to the inner wall of the limiting groove 6, and the limiting block 11 and the positioning block 9 mesh with each other. A telescopic rod 12 is fixedly connected to the outer wall of the telescopic block 10, with one end slidably connected to the inner wall of the adjusting rod 7 and the other end fixedly connected to a pressing block 13. A spring 14 is sleeved on the outer wall of the telescopic rod 12, with springs at both ends... The tooling is fixedly connected to the opposite sides of the telescopic block 10 and the adjusting rod 7, respectively. Through the cooperation of the limiting plate 5, the limiting groove 6, the adjusting rod 7, the adjusting plate 8 and the positioning mechanism, precise positioning is achieved. The positioning block 9 in the positioning mechanism meshes with the limiting block 11 on the inner wall of the limiting groove 6. The telescopic block 10 in the adjusting rod 7 can control the extension and retraction of the positioning block 9. The pressing block 13 facilitates operation, and the spring 14 provides the restoring force. During welding, the tooling can stably maintain the position of the workpiece, prevent the workpiece from shifting due to factors such as vibration during the welding process, ensure welding accuracy, improve welding quality, effectively avoid welding defects caused by inaccurate positioning, and reduce the defect rate.

[0022] Working principle of this utility model:

[0023] The compressor bracket assembly to be welded is placed on the clamping device at the top of the rotating base 4 and fixed in place by the clamping device to ensure that the workpiece will not move arbitrarily during the welding process. Depending on the welding requirements, if the angle of the workpiece needs to be adjusted in the horizontal direction, the adjusting plate 8 connected to the horizontal rotating base 2 can be rotated while pressing block 13. Pressing block 13 causes telescopic rod 12 and telescopic block 10 to slide within the adjusting rod 7. Telescopic block 10 compresses spring 14, causing positioning block 9 to retract into the adjusting rod 7, disengaging positioning block 9 from the limiting block 11 on the inner wall of the limiting groove 6. The adjusting plate 8, through the adjusting rod 7, causes the horizontal rotating base 2 to slide within the horizontal arc-shaped lower groove at the top of the fixed base 1. Because the bottom of the horizontal rotating base 2 is completely in contact with the inner wall of the groove, it can rotate smoothly in the horizontal direction, thereby causing the vertical rotating base 3, the rotating base 4, and the workpiece above to rotate together, achieving horizontal angle adjustment. After adjusting to the desired position, release pressing block 13. Due to the reciprocating force of spring 14, positioning block 9 extends out of the adjusting rod 7. Positioning block 9 engages with limiting block 11 again to lock the angle of horizontal rotating base 2. Similarly, to adjust the angle in the vertical direction, the adjusting plate 8 connected to horizontal rotating base 2 can be rotated while pressing block 13. The adjusting plate 8 drives the vertical rotating base 3 to slide in the vertical arc-shaped groove at the top of the horizontal rotating base 2 through the adjusting rod 7, thereby achieving vertical angle adjustment. In addition, the angle of the workpiece can be further precisely adjusted by rotating the self-rotating base 4. After rotating to the appropriate position, the torsion block 16 is rotated to drive the threaded bolt 15 to rotate, so that the bottom end of the threaded bolt 15 is in close contact with the top of the vertical rotating base 3, thereby locking the angle of the self-rotating base 4 to meet the welding requirements of different positions and angles. After the workpiece is adjusted to the appropriate angle and fixed, the welder can perform welding operations on the compressor bracket assembly. Because the tooling, through the cooperation of multiple bases and the action of the positioning mechanism, can stably hold the workpiece in the set position and angle, the workpiece will not shift or shake during the welding process, ensuring the accuracy and quality of the welding.
