[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 An embodiment of this utility model is provided: an auxiliary support device for processing thin-walled workpieces, including a device body 4, an adjusting bolt 1 threadedly connected to one side of the device body 4, a shaft 2 slidably disposed inside the device body 4, a front steel ball bolt 3 disposed on one side of the upper end of the device body 4, and an adjusting knob 5 connected to one side of the shaft 2.

[0024] Specifically, adjusting bolt 1 is used to lock the position of shaft 2 to ensure stable support. It is threadedly connected to the threaded hole of the device body 4, and its end can abut against shaft 2. By turning adjusting bolt 1, its extension length relative to device body 4 can be changed, thereby adjusting the position of shaft 2 to ensure precise contact between the workpiece edge and the device R part, improving the support fit. Shaft 2 can slide through the through hole of device body 4, with one end fixedly connected to adjusting knob 5, and the other end used to contact the workpiece. It can be extended and adjusted, and the fit with the workpiece is achieved by sliding. Alternatively, the front steel ball bolt 3 can be separated, and its end can abut against the shaft 2. After the shaft 2 is adjusted to a suitable position, tighten the front steel ball bolt 3. The friction between the steel ball and the shaft 2 will lock the shaft 2, preventing the shaft 2 from shifting during processing. The device body 4 is provided with a through hole for installing the shaft 2 and a threaded hole that mates with the adjusting bolt 1. The size of the through hole is adapted to the shaft 2 to ensure that the shaft 2 can slide smoothly. The adjusting knob 5 facilitates manual operation of the extension and retraction of the shaft 2. The overall fit achieves flexible support for thin-walled workpieces and prevents processing deformation.

[0025] Reference Figures 1-5 The adjusting bolt 1 and the device body 4 are both made of S45C material. The S45C material portions of the adjusting bolt 1 and the device body 4 are subjected to tip quenching treatment. The shaft 2 is made of SK4 material. The SK4 material portions of the shaft 2 are subjected to quenching and tempering treatment. The adjusting knob 5 is made of polyamide material and is black in color. The surfaces of the adjusting bolt 1, shaft 2, and device body 5 are all coated with a magnetite film. The tightening torque of the adjusting bolt 1 is 3.5N. m、8N m or 22N m, the stroke S of shaft 2 is 6mm, 10mm or 7.5mm, and the front steel ball bolt 3 is of type M6×1 with a depth of 12, M8×1.25 with a depth of 16 or M12×1.75 with a depth of 24.

[0026] Specifically, S45C is a high-quality carbon structural steel with high strength and toughness. After quenching, the hardness of its contact parts can be improved, enhancing the hardness and wear resistance of the adjusting bolt 1 and the device body 4. SK4 is a high-carbon steel, which can obtain high hardness and good toughness after quenching and tempering, giving the shaft 2 both strength and toughness, ensuring stable support. The polyamide adjusting knob 5 is lightweight and non-slip, and its black color makes it easy to identify the operating position. The iron oxide film forms a rust-proof protective layer, which can isolate air and moisture, preventing the adjusting bolt 1, shaft 2 and device body 4 from rusting, ensuring structural stability during long-term use. Different specifications of tightening torque, stroke and bolt type are available to meet the support requirements of thin-walled workpieces of different sizes.

[0027] This utility model proposes an auxiliary support device for processing thin-walled workpieces. This device excels in durability and safety, extending its service life and reducing workpiece damage. The device body and adjusting bolts are made of S45C material, with the tips hardened. The shaft is made of SK4 material and undergoes quenching and tempering treatment, significantly enhancing its overall strength and wear resistance. The iron oxide film formed on the surface isolates air and moisture, preventing corrosion of the adjusting bolts, shaft, and device body, further improving durability. The knob is made of polyamide material, combining lightweight and elasticity to reduce impact damage to the workpiece during operation. Its black appearance allows operators to quickly observe and identify the operating position, improving ease of use and safety, and comprehensively ensuring the stable and long-term operation of the device.

[0028] Working Principle: When installing a workpiece by pulling the shaft backward, the operator pulls the adjusting knob 5 backward, causing the shaft 2 to retract. At this time, the shaft 2 is held at its maximum stroke position by the built-in plunger, reserving space for workpiece installation. After placing the thin-walled workpiece at the machining station, gently push the adjusting knob 5 to slowly bring the shaft 2 closer to and contact the workpiece. During operation, the force must be controlled to avoid workpiece deformation due to excessive force. After confirming that the shaft 2 and workpiece are tightly fitted, tighten the front steel ball bolt 3. The friction between the steel ball and the shaft 2 locks the shaft 2, completing the support and fixation, and machining can begin. When installing a workpiece without pulling the shaft backward, first tighten the adjusting bolt 1 to adjust its position relative to the device. The extension of body 4 ensures precise contact between the workpiece edges and corners and the device's R section. After placing the workpiece in the machining station and confirming its correct position, tighten the front steel ball bolt 3. The friction between the steel ball and shaft 2 locks shaft 2 in place, ensuring that shaft 2 will not shift during machining, thus achieving support and fixation. After machining, loosen the front steel ball bolt 3 and adjust knob 5 to retract shaft 2, separating it from the workpiece. The machined thin-walled workpiece can then be removed. This device, with its flexible adjustment method and stable locking structure, can adapt to the support requirements of different thin-walled workpieces, effectively reducing workpiece deformation during machining and improving machining accuracy and quality.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
