[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example:

[0019] like Figure 1 As shown, this utility model provides a milling machine fixture.

[0020] The system includes a base 1, a fixed seat 2, and a support rod seat 3. The fixed seat 2 and the support rod seat 3 are both mounted on the base 1. The fixed seats 2 are arranged in several groups, and the groups of fixed seats 2 are distributed in a circular pattern along the surface of the base 1. The support rod seats 3 are also arranged in several groups, and the groups of support rod seats 3 are distributed in a circular pattern along the surface of the base 1. A clamping nut 4 and a clamping block 5 are mounted on the support rod seat 3. The clamping block 5 is located at the upper end of the support rod seat 3, and the clamping nut 4 is located at the upper end of the support rod seat 3 and above the clamping block 5. The workpiece to be processed is placed on the fixed seat 2. The clamping nut 4 is rotated downwards, thereby driving the clamping block 5 downwards, thus clamping and fixing the workpiece on the fixed seat 2.

[0021] The fixed seat 2 and the support rod seat 3 are distributed in a circle along the surface of the base 1 to form a uniform clamping force, which avoids the workpiece from deforming due to uneven force and improves the machining accuracy. The workpiece can be quickly clamped and released by the threaded engagement of the clamping nut 4 and the clamping block 5, which shortens the auxiliary time and improves the machining efficiency. The fixed seat 2 and the support rod seat 3 are set independently, which makes it easy to adjust the layout according to the workpiece size and enhances the versatility of the fixture.

[0022] Optionally, a protective layer is provided on the lower surface of the clamping block 5 to protect the surface of the workpiece.

[0023] The protective layer on the lower surface of the clamping block 5, such as rubber, plastic or soft metal, can prevent scratches on the workpiece surface during clamping. It is especially suitable for precision parts or easily damaged materials such as aluminum alloys, reducing secondary repair costs. The protective layer can absorb part of the clamping force, avoid rigid contact that leads to local stress concentration on the workpiece, and reduce the risk of deformation.

[0024] Optionally, the base 1 is provided with mounting holes, which are set in several groups and evenly spaced apart. The base 1 is fixedly connected to the milling machine's worktable via the mounting holes using bolts.

[0025] Multiple sets of evenly spaced mounting holes are fixed to the worktable with bolts, increasing the contact area, dispersing the weight of the fixture and the vibration and impact force during processing, improving overall stability, and the mounting hole layout can be matched with different worktable hole positions to improve the compatibility of the fixture.

[0026] Optionally, the base 1 is provided with lifting bolts 6, and the lifting bolts 6 are configured in several groups, with the several groups of lifting bolts 6 distributed in a circle along the surface of the base 1.

[0027] The circularly distributed lifting bolts 6 stabilize the center of gravity of the clamp, preventing it from tilting or falling off during lifting, ensuring operational safety. The multi-point lifting distributes the force, preventing structural deformation of the clamp due to single-point force during transportation.

[0028] Optionally, the support rod seat 3 and the base 1 are integrally formed, or the support rod seat 3 is fixedly welded to the base 1.

[0029] The one-piece molding or welding process eliminates the connection gap between the support rod seat 3 and the base 1, improves torsional stiffness, is suitable for heavy-duty processing scenarios, eliminates the risk of welding cracks or loosening, extends the service life of the fixture, and reduces the frequency of maintenance.

[0030] Optionally, the lower side wall of the fixed base 2 is provided with a first positioning hole, and the surface of the base 1 is provided with a second positioning hole corresponding to the first positioning hole. The fixed base 2 and the base 1 are fixedly connected by bolts through the first positioning hole and the second positioning hole.

[0031] The bolt connection between the first positioning hole and the second positioning hole ensures that the mounting position of the fixed seat 2 is accurate, improves the consistency of repeated clamping, meets the needs of batch processing, and the fixed seat 2 can be quickly disassembled and replaced, making it easy to adjust the function of the fixture.

[0032] Optionally, the first positioning hole is configured as several groups, with the several groups of first positioning holes evenly spaced apart, and the first positioning hole and the second positioning hole are configured in a one-to-one correspondence.

[0033] The evenly spaced first positioning holes correspond one-to-one with the second positioning holes, which enhances the connection reliability between the fixed seat 2 and the base 1, prevents the fixed seat 2 from becoming loose due to processing vibration, and provides design redundancy for fixture upgrades such as increasing the number of fixed seats 2 or adjusting the layout.

[0034] Both the fixed base 2 and the support rod base 3 of this application adopt a circular distribution to form a double ring support structure. This layout makes the clamp more uniformly stressed, especially suitable for the processing of circular or symmetrical workpieces, effectively avoiding clamping deformation and improving processing accuracy. The support rod base 3 integrates the clamping nut 4 and the clamping block 5, which can achieve quick clamping with one hand through thread transmission. Compared with the traditional manual clamping device, the operation time is greatly shortened.

[0035] The support rod 3 and the base 1 are fixed by integral molding or welding, eliminating assembly gaps and improving overall rigidity. Compared with a split structure, it has enhanced vibration resistance and is suitable for high-speed milling scenarios.

[0036] The fixed base 2 is bolted to the second positioning hole of the base 1 through multiple sets of evenly spaced first positioning holes, realizing modular installation. The one-to-one correspondence of the positioning holes can eliminate clamping deviation and ensure the repeatability accuracy of each clamping.

[0037] The base 1 is equipped with annular lifting bolts 6, which, together with the overhead crane, enable the quick and easy transfer of the entire fixture. This design reduces tooling changeover time, is suitable for the needs of flexible production lines, and greatly improves equipment utilization.

[0038] A protective layer is added to the lower surface of the clamping block 5, using elastic materials such as nylon / rubber to avoid indentations caused by direct metal contact. It is particularly suitable for precision parts processing. By replacing the fixed base 2 of different specifications, it can be adapted to workpieces of various sizes. With the ring distribution characteristics, it supports multi-point synchronous clamping of complex geometries such as gears and turbines, expanding the applicability of the fixture.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
