[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 1-6 An embodiment of this utility model provides an auxiliary support device, including a device body 1, an installation hole 2 on one side of the upper end of the device body 1, a shaft 3 slidably disposed inside the device body 1, a first locking mechanism 4 and a second locking mechanism 6 disposed on one side of the device body 1, and a spring 5 disposed at the lower end inside the device body 1.

[0024] Specifically, the device body 1 serves as the basic support structure, with a precision axial through hole of 12mm in diameter machined inside to accommodate the shaft 3. The threaded hole on its side wall mates with the internal hexagon bolt of the first locking mechanism 4, allowing the device to be fixed in the desired position through the mounting hole 2. One end of the shaft 3 is fixed with a front steel ball for direct contact with the workpiece. The shaft 3 can slide within the axial through hole of the device body 1, with a sliding stroke S of 6mm, which is flexibly adjustable to adapt to workpieces of different sizes and processing conditions. The first locking mechanism 4 and the second locking mechanism 6 can be selectively installed according to usage requirements. After installation, they can effectively lock the shaft 3 to prevent displacement during operation. The spring 5 provides preload force to the shaft 3, which not only assists the shaft 3 in flexible movement but also enhances the support stability for the workpiece, ensuring reliable processing.

[0025] Reference Figures 1-4 The device body 1 is made of S45C material, and the shaft 3 is made of SK95 material after quenching and tempering. The surfaces of both the device body 1 and the shaft 3 are covered with a ferric oxide film.

[0026] This utility model proposes an auxiliary support device. The main body of the device is made of S45C material, which has high strength and good toughness and can stably withstand the workpiece pressure transmitted by the shaft. The shaft is made of SK95 material and has been quenched and tempered, which has high hardness and is not easy to bend, ensuring the structural accuracy in contact with the workpiece. The iron oxide film on the surface of both can isolate corrosive media, reduce friction and wear, and extend service life. The 6mm sliding stroke of the shaft can flexibly adapt to workpieces of different sizes. The 0.6kN-9kN support force and 0-11N lifting force can effectively balance the force on the workpiece, prevent vibration and deformation during processing, and ensure processing accuracy.

[0027] Specifically, the device body 1 is made of S45C material, which has high strength and toughness, providing a stable support foundation for the entire device. During operation, it can firmly withstand the workpiece pressure transmitted by the shaft 3, ensuring that it does not deform and guaranteeing the stability of the overall structure of the device. The shaft 3 is made of SK95 material, which, after quenching and tempering, has significantly increased hardness, enabling it to withstand the pressure applied by the workpiece without bending easily, effectively maintaining the structural accuracy when in contact with the workpiece. Both the device body 1 and the shaft 3 are covered with a magnetite film. This film adheres tightly to the material surface, isolating oxygen in the air, as well as cutting fluid, moisture, and other corrosive substances in the processing environment, thereby preventing corrosion of the device body 1 and the shaft 3. At the same time, the hardness of the magnetite film is higher than that of the base material, which can reduce the friction and wear between the shaft 3 and the inner wall of the through hole of the device body 1 during sliding, reduce the wear rate of components, significantly extend the service life of the shaft 3, and improve the overall durability of the device.

[0028] Reference Figures 1-6The first locking mechanism 4 is a front-end steel ball socket head cap screw type, including a socket head cap screw with a specification of M3×0.5-5L, M6×1-16L, M8×1.25-20L, M10×1.5-25L or M12×1.75-30L. The second locking mechanism 6 is a knurled nut type, including a knurled nut and a front-end steel ball screw. The knurled nut is an M2 specification. The supporting force of the device is 0.6kN-9kN, and the lifting force is 0-11N.

[0029] Specifically, the first locking mechanism 4 uses the steel ball at the front end of the hexagon socket bolt to press the shaft 3 and lock it using friction. The hexagon socket bolt type can be tightened with a wrench and is suitable for scenarios requiring higher locking force. The second locking mechanism 6 uses a knurled nut to manually tighten the front steel ball bolt to enhance locking. Users can choose to install one of them separately as needed to flexibly adapt to different tightening requirements. The knurled nut type can be adjusted by hand. The device provides a support force of 0.6kN-9kN and a lifting force of 0-11N, which can effectively balance the force on the workpiece during processing and prevent the workpiece from shaking or deforming.

[0030] Working Principle: When using the auxiliary support device, firstly, the device is fixed in the designated position on the processing equipment through the mounting hole 2 at the upper end of the device body 1, providing a stable foundation for subsequent support operations. The device body 1 is made of S45C material, which, with its high strength and toughness, can stably withstand the workpiece pressure transmitted by the shaft 3, ensuring that it does not deform. According to the size of the workpiece and the processing conditions, the position of the shaft 3 in the axial through hole of the device body 1 is adjusted. The shaft 3 can slide along the through hole (sliding stroke S is 6mm), and the steel ball at its front end directly contacts the workpiece. The preload of the spring 5 provides initial support force for the shaft 3, making the shaft 3 fit tightly against the workpiece surface and initially balancing the force on the workpiece. The shaft 3 is made of SK95 material and has been quenched and tempered, resulting in high hardness and resistance to bending, which can accurately maintain the structural accuracy of contact with the workpiece. The iron oxide film on the surface of the device body 1 and the shaft 3 can not only isolate corrosive media to prevent rust, but also reduce friction and wear when the shaft 3 slides, extending its service life. When the shaft 3 is adjusted to the appropriate position... After installation, select either the first locking mechanism 4 or the second locking mechanism 6 according to the locking requirements. If a higher locking force is required, install the first locking mechanism 4 and tighten the hex bolt (sizes can be selected from M3×0.5-5L to M12×1.75-30L) with a wrench. The steel ball at the front end of the bolt presses against the shaft 3, locking the shaft 3 with friction to prevent displacement. If convenient adjustment is required, select the second locking mechanism 6 and manually tighten the M2 knurled nut. This will cause the steel ball bolt at the front end to press against the shaft 3, achieving quick locking. During workpiece processing, the device provides a support force of 0.6kN-9kN and a lifting force of 0-11N, which are transmitted to the workpiece through the steel ball at the front end of the shaft 3. This effectively balances the force on the workpiece and prevents the workpiece from being affected by vibration or deformation, thus improving the processing accuracy. The spring 5 continuously provides a preload to the shaft 3, which helps the shaft 3 to flexibly adapt to the small displacement of the workpiece and ensures the stability of the support. After processing is completed, the first locking mechanism 4 or the second locking mechanism 6 is released, and the shaft 3 is reset under the action of the spring 5, making it easy to adjust and use next time.

[0031] 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.
