It can simultaneously complete the limiting and fixing of two sets of support bases, which facilitates the milling of the side of the support base. It can be flexibly applied to the fixing and installation of support bases of different sizes, and improves the milling effect.

[0003] Patent document CN119435450A describes an elastic support base for an energy-saving fan, including a base plate. A balancing component is provided at the bottom of the base plate. The balancing component includes a groove, which is formed at the bottom of the base plate. A central axis point is fixedly connected to the side wall of the groove. A main balance rod is rotatably connected to the bottom of the central axis point. A pivot point is rotatably connected to both ends of the main balance rod. A secondary balance rod is rotatably connected to the outside of the pivot point. A support rod is rotatably connected to both ends of the bottom of the secondary balance rod.

The first fixing screw passes through the main tooling plate and the base plate. A pair of upright plates are fixedly connected to the top of the main tooling plate.

[0004] Existing wind turbine support bases have certain shortcomings in milling operations. During milling, the support base is fixed by a tooling structure. A set of support bases consists of two parts, left and right. However, a single tooling structure can only fix one set of support bases at a time. This requires a set of support bases to be milled twice, reducing its processing efficiency. Secondly, different models of support bases have different dimensions and different inner groove sizes. Traditional tooling structures cannot meet the needs of fixing different models of support bases, reducing their applicability. Summary of the Invention

[0005] This invention provides a fixing fixture for processing wind turbine vibration damping support seats. It solves the problem in existing technologies where, during milling, the fixture structure is used to limit and fix the support seat. A set of support seats consists of two parts, left and right, and a single fixture structure can only completely fix one set of support seats at a time. This requires milling one set of support seats twice, reducing processing efficiency. Furthermore, different models of support seats have different dimensions and different inner groove sizes; traditional fixture structures cannot meet the limiting and fixing requirements of different models of support seats, reducing their applicability. A fixing fixture for processing wind turbine vibration damping support base includes a fixed base plate, a first upright plate, and a shelf plate. There are two sets of first upright plates, both sets of which are fixed to the upper outer surface of the fixed base plate. The shelf plate is fixedly installed on the upper outer surface of the two sets of first upright plates. Two sets of second upright plates are fixedly installed on the upper outer surface of the shelf plate. Pressure rods for fixing the processed parts are installed on the top of the two sets of second upright plates and the two sets of first upright plates. Several sets of positioning nuts for use with the processed parts are provided on the upper outer surface of the fixed base plate and the shelf plate, as well as on one side of the outer surface of the first and second upright plates.

[0006] As a further technical solution of the present invention, the front ends of the first and second upright plates are provided with limiting clips for fixing the workpiece. The limiting clips include a moving block and a fixing clip. The fixing clip is fixedly installed on one side of the moving block. During operation, the fixing clip of the limiting clip can be used to clamp and fix the side of the workpiece when it is installed, thereby improving the stability of the workpiece during milling.

[0007] As a further technical solution of the present invention, a T-shaped seat is movably installed on the other side of the movable block. The T-shaped seat and the movable block are movably connected by a first lead screw. The outer surfaces of the fixed base plate, the shelf plate, the first vertical plate and the second vertical plate are all provided with mating grooves. During operation, according to the width of the workpiece, the first lead screw is rotated to drive the movable block to move using the threaded structure. The movable block drives the fixed clamp to move, so that the fixed clamp is clamped and fixed on both sides of the workpiece, thereby completing the reinforcement operation of the workpiece. The T-shaped seat uses bolts to fix the installation of the limiting clamp.

[0008] As a further technical solution of the present invention, an adjusting plate is movably installed at the bottom of the fixed base plate. The fixed base plate and the adjusting plate are movably connected by a second lead screw. During operation, by rotating the second lead screw, the second lead screw drives the fixed base plate to move using the threaded structure, thereby adjusting the milling position of the two sets of workpieces on the fixed base plate.

[0009] As a further technical solution of the present invention, the bottom of the adjustment plate is fixedly installed with a support base, and the upper outer surface of the adjustment plate is provided with a sliding groove for use with the fixed base plate. By using the sliding groove to connect with the fixed base plate, the accuracy of the fixed base plate when moving can be improved, and the deviation of the processed part during movement can be avoided.

[0010] As a further technical solution of the present invention, the pressure rod and the second upright plate, as well as the pressure rod and the first upright plate, are all fixed by bolts. Two sets of docking sliders are movably installed on the inner side of the pressure rod. By using the setting of the pressure rod, the upper part of the workpiece is limited and fixed when the workpiece is installed and fixed. Because the inner side of the workpiece is provided with an arc-shaped groove, the fixed position of the pressure rod needs to be adjusted according to the structural characteristics of the workpiece. The docking sliders can move arbitrarily within the pressure rod to adjust their fixed position.

[0011] As a further technical solution of the present invention, an adjusting bolt is movably installed at the inner middle position of the docking slider. The adjusting bolt and the docking slider are connected by threads. During operation, by rotating the adjusting bolt, the height of the circular pad can be adjusted up and down, so that the circular pad abuts against the upper end of the workpiece, thereby completing the limiting and fixing of the upper part of the workpiece.

[0012] As a further technical solution of the present invention, a circular pad is provided at the lower end of the adjusting bolt, and the adjusting bolt and the circular pad are movably connected. The circular pad is used to fix the upper end of the workpiece, and when the workpiece and the circular pad are in contact, the movably provided circular pad can prevent the workpiece from rotating on the surface of the workpiece, thereby reducing friction on the workpiece.

[0013] As a further technical solution of the present invention, both outer surfaces of the docking slider are fixedly installed with docking parts, and the inner side of the pressure rod is provided with a limiting groove for use with the docking parts. The upper surface of the limiting groove is a toothed structure, and the lower surface of the limiting groove is a grooved structure, so that the limiting groove can satisfy the sliding and limiting fixation of the docking slider.

[0014] As a further technical solution of the present invention, a number of toothed chucks are fixedly installed on the upper outer surface of the docking part, and a slide bar is provided on the lower outer surface of the docking part. During operation, in the non-fixed state, the slide bar at the lower end of the docking part is affected by the weight of the docking slider itself, so that the slide bar at the lower end of the docking part is connected with the slide groove structure at the lower part of the limiting slide groove, allowing the user to slide the docking slider arbitrarily and adjust the position of the docking slider in the limiting slide groove. When the circular pad moves to the corresponding position, the adjusting bolt is rotated, so that the adjusting bolt drives the circular pad to move down using the thread structure, thereby causing the circular pad and the upper end of the workpiece to abut against each other. As the adjusting bolt continues to rotate, the reaction force of the circular pad is applied to the docking slider, causing the docking slider to move upward, so that the toothed chucks at the upper part of the docking part are connected with the toothed groove structure of the limiting slide groove, thus completing the limiting and fixing between the docking slider and the pressure rod.

[0015] The beneficial effects of the present invention are as follows: By fixing the base plate and the layer plate, the present invention can simultaneously complete the limiting and fixing of two sets of support seats when the fixed tooling for processing the wind power vibration damping support seat is used, thereby improving the efficiency of milling the support seat and improving the stability of the support seat during processing and fixing. In actual use, the two sets of workpieces are placed on the upper ends of the fixed base plate and the shelf plate, respectively. According to the milling height of the workpieces, positioning nuts are installed on the upper ends of the fixed base plate and the shelf plate. The positioning nuts support the bottom of the support base. By rotating the positioning nuts, the height of the positioning nuts is adjusted using the thread structure, thereby adjusting the support height of the workpieces. Next, the positioning nuts on the sides of the first and second upright plates are adjusted so that the positioning nuts of the first and second upright plates abut against the two sides of the workpieces, limiting and fixing the two sides of the workpieces. Next, according to the width of the workpieces, the first lead screw is rotated so that the first lead screw drives the moving block to move using the thread structure. The moving block drives the fixed clamp to move, so that the fixed clamp is clamped and fixed on the two sides of the workpieces, thereby completing the reinforcement operation of the workpieces. The T-shaped seat uses bolts to fix the installation of the limiting clamps, and the limiting clamps improve the stability of the workpieces during installation. Finally, pressure bars are added to the upper ends of the first and second upright plates to complete the reinforcement operation of the upper end of the workpieces. By setting up pressure rods and docking sliders, the fixed tooling for processing the wind power vibration damping support seat has an adjustable press-fitting and fixing structure when in use. It can be adjusted according to the size of the groove of the support seat, thereby meeting the press-fitting and fixing of support seats of different specifications. In actual use, when the pressure rod is not fixed, the weight of the docking slider causes the slide bar at the lower end of the docking part to engage with the slide groove structure at the lower part of the limiting slide groove. This allows the user to slide the docking slider freely and adjust its position within the limiting slide groove. When the circular pad moves to the corresponding position on the upper end of the workpiece, the adjusting bolt is rotated, causing the adjusting bolt to drive the circular pad downwards using its threaded structure. This causes the circular pad and the upper end of the workpiece to abut against each other. The movable circular pad prevents it from rotating on the surface of the workpiece, reducing friction. As the adjusting bolt continues to rotate, the reaction force of the circular pad is applied to the docking slider, causing it to move upwards. This allows the toothed chuck at the upper part of the docking part to engage with the toothed groove structure of the limiting slide groove, completing the limiting and fixing of the docking slider and the pressure rod.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0019] like Figures 1-5 As shown, the fixed fixture for processing wind turbine vibration damping support includes a fixed base plate 1, a first upright plate 5, and a shelf plate 7. There are two sets of first upright plates 5, both of which are fixed to the upper outer surface of the fixed base plate 1. The shelf plate 7 is fixedly installed on the upper outer surface of the two sets of first upright plates 5. Two sets of second upright plates 8 are fixedly installed on the upper outer surface of the shelf plate 7. The top of the two sets of second upright plates 8 and the two sets of first upright plates 5 are all equipped with pressure rods 6 for fixing the processing part 4. The processing part 4 is the support to be processed. The upper outer surface of the fixed base plate 1 and the shelf plate 7, as well as one side outer surface of the first upright plate 5 and the second upright plate 8, are provided with several sets of positioning nuts 16 for use with the processing part 4.

[0020] The front ends of the first upright plate 5 and the second upright plate 8 are both provided with limiting clips 9 for fixing the workpiece 4. The limiting clips 9 include a moving block 12 and a fixing clip 13. The fixing clip 13 is fixedly installed on one side of the moving block 12. During operation, the fixing clip 13 of the limiting clips 9 can be used to clamp and fix the side of the workpiece 4 when it is installed, thereby improving the stability of the workpiece 4 during milling.

[0021] A T-shaped seat 11 is movably installed on the other side of the movable block 12. The T-shaped seat 11 and the movable block 12 are movably connected by a first lead screw 14. The outer surfaces of the fixed base plate 1, the shelf 7, the first upright plate 5 and the second upright plate 8 are all provided with mating grooves 10. During operation, according to the width of the workpiece 4, the first lead screw 14 is rotated, so that the first lead screw 14 drives the movable block 12 to move using the threaded structure. The movable block 12 drives the fixed clamp 13 to move, so that the fixed clamp 13 is clamped and fixed on both sides of the workpiece 4, thereby completing the reinforcement operation of the workpiece 4. The T-shaped seat 11 uses bolts to fix the installation of the limiting clamp 9.

[0022] An adjusting plate 2 is movably installed on the bottom of the fixed base plate 1. The fixed base plate 1 and the adjusting plate 2 are movably connected by a second lead screw 15. During operation, by rotating the second lead screw 15, the second lead screw 15 drives the fixed base plate 1 to move using the thread structure, thereby adjusting the milling position of the two sets of workpieces 4 on the fixed base plate 1.

[0023] The bottom of the adjusting plate 2 is fixedly installed with a support base 3. The upper outer surface of the adjusting plate 2 is provided with a sliding groove for use with the fixed base plate 1. By using the sliding groove to connect with the fixed base plate 1, the accuracy of the fixed base plate 1 when moving can be improved, and the deviation of the processed part 4 when moving can be avoided.

[0024] The pressure rod 6 and the second upright plate 8, as well as the pressure rod 6 and the first upright plate 5, are all fixed by bolts. Two sets of docking sliders 18 are movably installed on the inner side of the pressure rod 6. By using the setting of the pressure rod 6, the upper part of the workpiece 4 is limited and fixed when it is installed and fixed. Because the inner side of the workpiece 4 is provided with an arc-shaped groove, the fixed position of the pressure rod 6 needs to be adjusted according to the structural characteristics of the workpiece 4. The docking sliders 18 can move arbitrarily within the pressure rod 6 to adjust their fixed position.

[0025] An adjusting bolt 19 is movably installed at the middle of the inner side of the docking slider 18. The adjusting bolt 19 and the docking slider 18 are connected by threads. During operation, by rotating the adjusting bolt 19, the height of the circular pad 21 can be adjusted up and down, so that the circular pad 21 abuts against the upper end of the workpiece 4, thereby completing the limiting and fixing of the upper part of the workpiece 4.

[0026] A circular pad 21 is provided at the lower end of the adjusting bolt 19. The adjusting bolt 19 and the circular pad 21 are movably connected. The circular pad 21 is used to fix the upper end of the workpiece 4. At the same time, when the workpiece 4 and the circular pad 21 are in contact, the movably provided circular pad 21 can prevent the workpiece 4 from rotating on the surface of the workpiece 4, thereby reducing friction on the workpiece 4.

[0027] Both outer surfaces of the docking slider 18 are fixedly equipped with docking parts 20. The inner side of the pressure rod 6 is provided with a limiting groove 17 that cooperates with the docking parts 20. The upper surface of the limiting groove 17 is a toothed structure and the lower surface of the limiting groove 17 is a grooved structure, so that the limiting groove 17 can satisfy the sliding and limiting fixation of the docking slider 18.

[0028] Several sets of toothed chucks 22 are fixedly installed on the upper outer surface of the docking part 20, and a slide bar is provided on the lower outer surface of the docking part 20. During operation, in the non-fixed state, the slide bar at the lower end of the docking part 20 is affected by the weight of the docking slider 18 itself, so that the slide bar at the lower end of the docking part 20 is connected with the slide groove structure at the lower part of the limiting slide groove 17, allowing the user to slide the docking slider 18 arbitrarily and adjust the position of the docking slider 18 in the limiting slide groove 17. When the circular pad 21 moves to the corresponding position, the adjusting bolt 19 is rotated, so that the adjusting bolt 19 drives the circular pad 21 to move down using the thread structure, so that the circular pad 21 and the upper end of the workpiece 4 abut against each other. As the adjusting bolt 19 continues to rotate, the reaction force of the circular pad 21 is applied to the docking slider 18, so that the docking slider 18 moves upward, so that the toothed chucks 22 at the upper part of the docking part 20 are connected with the toothed groove structure of the limiting slide groove 17, thus completing the limiting and fixing between the docking slider 18 and the pressure rod 6.

[0029] The fixed fixture for processing wind turbine vibration damping support bases involves placing two sets of processed parts 4 on the upper ends of the fixed base plate 1 and the shelf plate 7, respectively. Based on the milling height of the processed parts 4, positioning nuts 16 are installed on the upper ends of the fixed base plate 1 and the shelf plate 7. These positioning nuts 16 support the bottom of the support base 3. By rotating the positioning nuts 16, the working height of the positioning nuts 16 is adjusted using the threaded structure, thereby adjusting the support height of the processed parts 4. Next, the positioning nuts 16 on the sides of the first vertical plate 5 and the second vertical plate 8 are adjusted so that the positioning nuts 16 on the first vertical plate 5 and the second vertical plate 8 abut against both sides of the processed parts 4. First, the two sides of the workpiece 4 are limited and fixed. Then, according to the width of the workpiece 4, the first lead screw 14 is rotated, so that the first lead screw 14 drives the moving block 12 to move through the thread structure. The moving block 12 drives the fixed clamp 13 to move, so that the fixed clamp 13 is clamped and fixed on both sides of the workpiece 4, thereby completing the reinforcement operation of the workpiece 4. The T-shaped seat 11 uses bolts to fix the installation of the limiting clamp 9. The limiting clamp 9 is used to improve the stability of the workpiece 4 during installation. Finally, pressure rods 6 are added to the upper end of the first vertical plate 5 and the second vertical plate 8 to complete the reinforcement operation of the upper end of the workpiece 4. In the non-fixed state of the pressure rod 6, the weight of the docking slider 18 causes the slide bar at the lower end of the docking part 20 to engage with the slide groove structure at the lower part of the limiting slide groove 17, allowing the user to slide the docking slider 18 freely and adjust its position within the limiting slide groove 17. When the circular pad 21 moves to the corresponding position on the upper end of the workpiece 4, the adjusting bolt 19 is rotated, causing the adjusting bolt 19 to drive the circular pad 21 downward using its threaded structure, thereby causing the circular pad 21 and the upper end of the workpiece 4 to abut against each other. The movable circular pad 21 prevents it from rotating on the surface of the workpiece 4, reducing friction on the workpiece 4. As the adjusting bolt 19 continues to rotate, the reaction force of the circular pad 21 is applied to the docking slider 18, causing the docking slider 18 to move upward, thereby causing the toothed head at the upper part of the docking part 20 to engage with the toothed groove structure of the limiting slide groove 17, completing the limiting and fixing between the docking slider 18 and the pressure rod 6.

[0030] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
