[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example 1

[0027] Please see Figure 1-5 As shown, a tooling for machining a hinge seat in this embodiment includes a mounting plate 1, a hinge seat base plate 5, and two support plates 3;

[0028] The top two sides of the mounting plate 1 are slidably connected to the movable plate 4, and the bottom two sides of the movable plate 4 are connected to the top of the mounting plate 1 through a sliding structure. One side of the movable plate 4 is provided with a positioning structure that can be detachably connected to the top of the mounting plate 1.

[0029] A limit post 2 is provided on the top side of the mounting plate 1, and both ends of the limit post 2 are connected to two support plates 3 respectively through a connecting structure.

[0030] The bottom of the movable plate 4 is connected to the limit plate 8 through a vertical adjustment structure.

[0031] First, the hinge base plate 5 is accurately placed on top of the mounting plate 1. This step is fundamental to the machining process, ensuring that the hinge base plate 5 has a stable support platform. Next, the connecting structures at both ends of the limiting post 2 are connected to the circular holes of the two support plates 3 respectively. This design allows the support plates 3 to be connected to the limiting post 2 in a controllable and stable manner, thereby connecting the limiting post 2 to the top of the mounting plate 1. At this point, one end of each of the two support plates 3 is in contact with the top of the hinge base plate 5 and is stably placed. This contact method improves upon the complex process of welding and fixing the support plates vertically to the base plate in traditional machining, providing convenience for subsequent welding work.

[0032] Subsequently, the two movable plates 4 are moved to the top sides of the hinge base plate 5, respectively. Both bottom sides of the movable plates 4 are connected to the top of the mounting plate 1 via a sliding structure. This sliding structure allows the movable plates 4 to be flexibly adjusted according to the size and processing requirements of the hinge base plate 5. After being moved into place, the position of the movable plates 4 is fixed by a positioning structure to ensure that the movable plates 4 will not move during processing, thereby guaranteeing processing accuracy.

[0033] Finally, the vertical adjustment structure moves the limiting plate 8, bringing it into contact with the top of the hinge base plate 5. This step is crucial for clamping and limiting; the vertical adjustment of the limiting plate 8 not only accommodates hinge base plates 5 at different heights but also ensures stable clamping of the hinge base plate 5, preventing displacement during welding. At this point, the hinge base plate 5 and the two support plates 3 are stably limited, providing strong support for rapid and precise welding operations.

[0034] Example 2

[0035] Please see Figure 1-5 As shown, this embodiment of a hinge seat machining fixture includes a vertical adjustment structure comprising an adjusting screw 9 rotatably connected to the top of a limiting plate 8. One end of the adjusting screw 9 is threaded through a movable plate 4. Specifically, by rotating the adjusting screw 9 rotatably connected to the top of the limiting plate 8, with one end threaded through the movable plate 4, when it is necessary to adjust the height of the limiting plate 8 to accommodate hinge seat base plates 5 of different heights, simply rotate the adjusting screw 9. The threaded design of the adjusting screw 9 allows the limiting plate 8 to rise or fall stably and precisely. This achieves a stable clamping effect on the hinge seat base plate 5, ensuring close contact between the limiting plate 8 and the base plate regardless of its height changes, preventing displacement during welding, and improving machining accuracy and stability.

[0036] Both sides of the top of the limiting plate 8 are fixedly connected to guide rods 10, one end of which slides through the moving plate 4. A handle is connected to the top of the adjusting screw 9. Specifically, when the adjusting screw 9 is rotated to adjust the height of the limiting plate 8, the guide rods 10 slide within the moving plate 4, providing guidance and stability. This achieves the effect of keeping the limiting plate 8 stable and without wobbling during lifting and lowering, further improving processing accuracy and stability.

[0037] Example 3

[0038] Please see Figure 1-5As shown, this embodiment of a hinge seat machining fixture includes a fixing screw 16 fixedly connected to the end of the limiting post 2 and a fixing nut 15 threaded onto the outer ring of the fixing screw 16. The bottom of the limiting post 2 is connected to a fixing plate 14 via a column 13. The fixing plate 14 is bolted to the top of the mounting plate 1. Specifically, by passing the fixing screw 16 through the round hole of the support plate 3 and tightening the fixing nut 15, the support plate 3 and the limiting post 2 can be securely connected together. Simultaneously, the bolted connection between the fixing plate 14 and the mounting plate 1 ensures the stability of the entire structure. This achieves a firm and stable connection between the support plate 3, the limiting post 2, and the mounting plate 1, providing reliable support for subsequent welding work.

[0039] Both sides of the top of the mounting plate 1 are provided with sliding grooves 6. The sliding structure includes a sliding plate fixedly connected to the bottom of the movable plate 4 and slidably connected to the sliding grooves 6. Specifically, when it is necessary to move the movable plate 4 to accommodate hinge base plates 5 of different sizes, simply slide the movable plate 4 along the sliding grooves 6. This achieves the effect of flexibly and accurately adjusting the position of the movable plate 4, providing greater flexibility and adaptability for the processing.

[0040] The positioning structure includes a side plate 12 fixedly connected to the side wall of the sliding plate and a rod 11 that slides through the side plate 12 at one end. The top of the mounting plate 1 has several positioning holes 7 that match the rod 11. Specifically, when the moving plate 4 moves to the appropriate position, the rod 11 is inserted into the corresponding positioning hole 7 to fix the position of the moving plate 4. This achieves the effect of keeping the moving plate 4 stable and unmoving during processing, further ensuring the accuracy and stability of the processing.

[0041] This solution includes the following work process:

[0042] First, the hinge base plate 5 is accurately placed on top of the mounting plate 1, providing a stable support platform for the processing. Next, the limiting post 2 is connected to the support plate 3. Specifically, the fixing screw 16 is passed through the round hole in the support plate 3, and the support plate 3 is securely connected to the end of the limiting post 2 by tightening the fixing nut 15. Simultaneously, the bottom of the limiting post 2 is connected to a fixing plate 14 via a column 13, and the fixing plate 14 is then fixedly connected to the top of the mounting plate 1 by bolts, thus ensuring the stability of the entire structure.

[0043] Subsequently, the positions of the two movable plates 4 are adjusted according to the dimensions and processing requirements of the hinge base plate 5. Both sides of the bottom of the movable plate 4 are connected via a sliding structure, that is, the sliding plate is adapted to and slidably connected to the top of the mounting plate 1 via a groove 6, allowing the movable plate 4 to slide flexibly and accurately along the groove 6. Once the movable plate 4 has moved to the appropriate position, its position is fixed by a positioning structure, specifically by inserting the insert rod 11 into the corresponding positioning hole 7, ensuring that the movable plate 4 will not move during processing.

[0044] Finally, the vertical adjustment of the limiting plate 8 is performed. Guide rods 10, with one end sliding through the moving plate 4, are fixedly connected to both sides of the top of the limiting plate 8, serving a guiding and stabilizing function. By rotating the adjusting screw 9 connected to the top of the limiting plate 8, one end of which is threaded through the moving plate 4, the height of the limiting plate 8 can be stably and precisely adjusted to ensure tight contact with the top of the hinge base plate 5. A handle is attached to the top of the adjusting screw 9 for easy rotation and adjustment by the operator.
