Description

Technical Field

[0001] This utility model relates to the field of turning technology, specifically to a tooling suitable for turning thin-walled parts. Background Technology

[0002] Thin-walled parts, due to their poor rigidity and weak strength, are prone to deformation and vibration during turning due to clamping forces, cutting forces, and cutting heat. This makes it difficult to guarantee machining accuracy (such as roundness, cylindricity, and wall thickness uniformity) and surface quality. In conventional machining of thin-walled parts, the workpiece is clamped in a four-jaw chuck, suspended near the inside of the chuck without any support. Due to the poor rigidity of the part itself, severe vibration occurs when the spindle rotates at high speed, with end face runout exceeding 3mm. Dimensions are difficult to guarantee during machining, and tool wear is severe. The purpose of this invention is to increase the rigidity of the part by adding support at the suspended position, effectively reducing vibration during machining, improving machining quality and efficiency, and reducing tool wear.

[0003] The following methods are commonly used in the prior art to solve the above problems: (1) Process optimization method: The cutting force is reduced by using cutting parameters such as small depth of cut, high speed, and small feed rate, and by increasing the number of passes. This method is inefficient and has limited effect on workpieces with extremely poor rigidity.

[0004] (2) Dedicated rigid mandrel method: Design and manufacture a mandrel with an interference fit for a specific workpiece. This method is costly and has poor versatility. Furthermore, the interference fit itself may damage the workpiece or cause uneven support due to errors in the workpiece's inner hole. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a tooling suitable for turning thin-walled parts. This tooling can be fixed between the thin-walled part and the end face of the four-jaw chuck by means of T-bolts during the turning process of thin-walled parts, thereby supporting the suspended part at the bottom of the thin-walled part, ensuring the support rigidity, so as to facilitate subsequent turning processing, and improving the processing accuracy and efficiency.

[0006] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a tooling suitable for turning thin-walled parts includes a cylindrical support body, a threaded hole is machined at the center of one end of the cylindrical support body, and a first planar groove and a second planar groove are symmetrically machined on both sides of the cylindrical support body. The cylindrical support is fixedly installed on the top of the T-bolt of the four-jaw chuck through a threaded hole and supports the lower end face of the workpiece to be processed. The T-bolt is set inside the T-slot of the four-jaw chuck.

[0007] Preferably, the cylindrical support is made of round steel.

[0008] Preferably, the height of the cylindrical support body is set in various different specifications according to the distance between the groove on the jaw and the end face of the four-jaw chuck.

[0009] Preferably, the cylindrical support is evenly arranged in a circle at the location of the T-slot of the four-jaw chuck.

[0010] Preferably, the cylindrical support body and the jaws of the four-jaw chuck are arranged in an alternating manner.

[0011] The present invention has the following beneficial effects: 1. Significantly improves machining accuracy: Through internal support, the local rigidity of thin-walled parts in the machining area is greatly enhanced, effectively suppressing the "tool deflection" phenomenon and vibration caused by cutting force, ensuring the roundness, cylindricity and dimensional consistency of the parts, and improving surface roughness.

[0012] 2. High versatility and adaptability: One set of tooling can adapt to thin-walled parts with different diameters, thicknesses and materials.

[0013] 3. Simple operation and high efficiency: The clamping and disassembly process is simple and quick, which significantly improves production efficiency and is suitable for mass production.

[0014] In summary, this fixture can be fixed between the thin-walled part and the end face of the four-jaw chuck during the turning process of thin-walled parts by means of T-bolts, thereby supporting the suspended part at the bottom of the thin-walled part, ensuring support rigidity, so as to facilitate subsequent turning processing, and improving machining accuracy and efficiency.

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] See Figure 1-9 A tooling for turning thin-walled parts includes a cylindrical support 1. A threaded hole 2 is machined at the center of one end of the cylindrical support 1. A first planar groove 3 and a second planar groove 4 are symmetrically machined on both sides of the cylindrical support 1. The cylindrical support 1 is fixedly mounted on the top of a T-bolt 9 of a four-jaw chuck 8 via the threaded hole 2 and supported on the lower end face of the workpiece 7 to be machined. The T-bolt 9 is located inside a T-slot 6 of the four-jaw chuck 8. This tooling allows for the fixing of the thin-walled part between the workpiece and the end face of the four-jaw chuck during turning, thereby supporting the suspended bottom portion of the thin-walled part, ensuring support rigidity, facilitating subsequent turning, and improving machining accuracy and efficiency. In practical use, the cylindrical support 1 is fixed on the T-bolt 9, and the end face of the part to be processed 7 is supported on the top of the cylindrical support 1. Then, the part to be processed 7 is clamped by the jaw 5. After the part to be processed 7 is clamped, the lathe is started to process the part to be processed 7.

[0028] Furthermore, the first planar groove 3 and the second planar groove 4 facilitate the subsequent tightening and fixing of the cylindrical support 1 with the help of a wrench, so that it is fixed to the top of the T-bolt 9.

[0029] Furthermore, the cylindrical support 1 is made of round steel. Using round steel simplifies the manufacturing process, improves efficiency, and reduces costs.

[0030] Furthermore, the height of the cylindrical support 1 is configured in various different sizes based on the distance between the slot 10 on the jaw 5 and the end face of the four-jaw chuck 8. These different height dimensions allow for good adaptation to four-jaw chucks 8 of different sizes and specifications.

[0031] Furthermore, the cylindrical support 1 is evenly arranged circumferentially at the location of the T-slot 6 of the four-jaw chuck 8. By adopting a uniformly arranged circumferential installation, the support effect is ensured.

[0032] Furthermore, the cylindrical support 1 and the jaws 5 of the four-jaw chuck 8 are arranged in an alternating manner. By adopting an alternating arrangement, all-round support can be achieved for the end face of the workpiece 7 to be machined, thereby ensuring the reliability of the support and the rigidity during subsequent machining processes to prevent tool deflection.

[0033] The specific working process and principle of this utility model are as follows: When the workpiece 7 needs to be processed, first, place the T-bolt 9 into the T-slot 6 of the four-jaw chuck 8; then, screw the cylindrical support 1 into the T-bolt 9, placing one in each T-slot 6 position, for a total of 4, and lock the cylindrical support 1 to the T-bolt 9; place the workpiece 7 into the four-jaw chuck 8, with the height of the cylindrical support 1 matching the height of the slot 10 on the jaw 5, and the bottom surface of the workpiece 7 flush with the top surface of the cylindrical support 1; finally, lock the jaw 5, clamp the workpiece 7 with the jaw 5, and then start the lathe to process the workpiece 7.
