Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see Figure 1A preferred embodiment of this application shows a milling fixture for the teeth and cheek area of ​​a medical surgical forceps 4, comprising an oil circuit board 1, a clamping and positioning assembly 2, and a manual hydraulic pump 3. At least one clamping and positioning assembly 2 includes a first clamping block 21 disposed on the upper part of the oil circuit board 1 for clamping the teeth of the surgical forceps 4, a second clamping block 22 disposed in the middle of the oil circuit board 1 for clamping the cheek area of ​​the surgical forceps 4, and a finger ring positioning block 23 disposed on the lower part of the oil circuit board 1 for positioning the finger rings of the surgical forceps 4. The manual hydraulic pump 3 is disposed on the oil circuit board 1 and is used to cooperate with the oil circuit board 1 to drive the opening and closing of the first clamping block 21 and the second clamping block 22.

[0026] According to the embodiment of this utility model, by setting a first clamping block 21 and a second clamping block 22 on the oil circuit board 1, and cooperating with the manual hydraulic pump 3 to clamp the head teeth and jaw of the surgical forceps 4, not only can the labor intensity be reduced, but the clamping force is also large, which can increase the milling speed during production and reduce the vibration of the workpiece during milling; by setting at least one clamping and positioning component 2, multiple workpieces can be clamped and milled at the same time, improving processing efficiency; by setting a finger ring positioning block 23 to accurately position the finger ring of the surgical forceps 4, the stability of workpiece processing is improved.

[0027] The following detailed description uses specific examples:

[0028] Specifically, please see Figure 2 The finger ring positioning block 23 is provided with a positioning part 231. The inner side of the positioning part 231 has a positioning groove 232 for securing the surgical forceps 4 finger ring. The finger ring positioning block 23 is also provided with a positioning spring piece 233 for supporting the tail of the surgical forceps 4 finger ring. The positioning spring piece 233 securely holds and supports the surgical forceps 4 finger ring, not only ensuring zero displacement of the workpiece under hydraulic clamping but also suppressing the impact of milling vibration on positioning accuracy, significantly improving machining stability. Simultaneously, the positioning spring piece 233 is elastic, preventing obstruction when the surgical forceps 4 finger ring is inserted into the positioning groove 232, and returning to its original shape after insertion to cooperate with the positioning part 231 in positioning and securing the surgical forceps 4 finger ring, resulting in a more stable positioning effect.

[0029] Further, please see Figure 2 The bottom of the positioning part 231 is equipped with an adjustable positioning screw 234, which cooperates with the positioning groove 232 to position surgical forceps 4 finger rings of different sizes. The positioning screw 234 can be slightly adjusted according to different sizes of surgical forceps 4 finger rings, and can be compatible with various surgical forceps 4 workpieces with similar finger ring sizes without replacing the entire finger ring positioning block 23, thus improving the compatibility of the clamp. It should be noted that for surgical forceps 4 workpieces with different overall shapes and lengths, it is still necessary to replace the first clamping block 21, the second clamping block 22, and the finger ring positioning block 23 accordingly to ensure the effective clamping and positioning of the workpiece.

[0030] Further, please see Figure 1 and Figure 3 The hydraulic circuit board 1 is equipped with a hydraulic gauge 5, which is used to monitor the oil pressure within the hydraulic circuit board 1. This configuration allows the operator to visually monitor the clamping status and adjust or stop the pump in a timely manner based on the pressure reading, ensuring a constant and controllable clamping force. This avoids damage to the workpiece due to excessive tightness and also prevents processing accidents caused by slippage due to excessive looseness. In this embodiment, the oil pressure during clamping is set at approximately 400 Pa.

[0031] Specifically, please see Figure 1 and Figure 3 The top of the oil circuit board 1 is equipped with an oil seal screw 6. The oil seal screw 6 is located on the top of the oil circuit board 1, which can be used to add oil or vent air when necessary to maintain the oil circuit, ensure the sealing and stability of the oil circuit, and avoid the performance degradation of the fixture or equipment downtime caused by oil circuit leakage or oil contamination during the processing.

[0032] Further, please see Figure 1 and Figure 3 The milling fixture also includes a support base plate 7 and a reinforcing rib 8. The oil passage plate 1 is vertically arranged on the support base plate 7, and the reinforcing rib 8 is arranged between the support base plate 7 and the oil passage plate 1.

[0033] Specifically, please see Figure 2 In this embodiment, there are two clamping and positioning components 2, which are symmetrically arranged along the vertical axis of the center of the oil circuit plate 1. This allows for simultaneous parallel clamping and milling of the head and cheek of two surgical forceps 4, not only doubling the single-feed capacity but also maximizing the utilization of machine tool processing time and improving batch production efficiency.

[0034] When using this milling fixture, it is first fixed to the CNC machine tool worktable, sealed with oil seal screws 6, and connected to the manual hydraulic pump 3 and oil circuit. The position of the positioning screws 234 is finely adjusted according to the model of the surgical forceps 4, and the two surgical forceps 4 are inserted into the corresponding positioning grooves 232 in sequence, so that the head and cheek of the surgical forceps 4 are respectively in the corresponding clamping blocks. After operating the manual hydraulic pump 3 to the predetermined pressure, a large thrust is generated to clamp the surgical forceps 4. After the clamping is stable, the head and cheek of the surgical forceps 4 are directly milled. After the machining is completed, the pressure is released and the surgical forceps 4 workpiece is removed, completing a two-piece milling in one step, which greatly improves the machining efficiency and stability.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
