[0002] In the automotive manufacturing industry, the machining of automotive axle components is a crucial step. The precision and stability of these axles directly affect the overall performance and safety of the vehicle. However, existing clamping methods for automotive axles have many shortcomings during machining. Currently, the clamping of automotive axles mainly relies on traditional fixtures and clamping methods. These fixtures typically include various forms of chucks, collets, or centers, which fix the axle to the machine tool table using mechanical or hydraulic force. When fixing the axle, one end is usually clamped and fixed, and the other end is restrained by a center. However, the outer wall of the clamped end of the axle is difficult to machine, requiring the axle to be flipped over before machining. Furthermore, this existing clamping method is particularly difficult when machining eccentric shafts within automotive axles. Therefore, we propose a stabilizing and fixing device for machining automotive parts on machine tools. Utility Model Content

[0024] like Figure 1-5As shown, a stabilizing and fixing device for machining automotive parts using a machine tool 1 includes a machine tool 1. A protective cover 2 is slidably installed on the upper surface of the machine tool 1. Fixing plates 7 are fixedly installed at both ends of the upper surface of the machine tool 1.

A milling body 3 is fixedly installed on the upper surface of the machine tool 1 between the two sets of limiting components.
[0025] The automotive part shaft to be processed is fixed by the limiting components set at both ends of the upper surface of the machine tool 1. The automotive part shaft can be processed by the milling body 3 set on the upper surface of the machine tool 1. The milling body 3 in this device is a common existing technology and will not be described in detail here. The outer wall of the automotive part shaft can be processed and polished by the milling body 3. The automotive part shaft is placed in front of the two sets of limiting components. The user can adjust the length of the two electric telescopic rods 8 according to the length of the automotive part shaft, and then fix the automotive part shaft between the two sets of limiting components.
[0026] like Figure 3 As shown, the limiting assembly includes a movable frame 6 fixedly connected to the end of the electric telescopic rod 8. The lower end of the movable frame 6 is slidably connected to the upper surface of the machine tool 1. A rotating cylinder 9 is fixedly installed on the upper outer wall of the movable frame 6. A hydraulic cylinder 10 is fixedly installed on the outer wall of the lower end of the rotating cylinder 9. A center 15 is fixedly installed at the output end of the hydraulic cylinder 10, and the center 15 is located inside the rotating cylinder 9. A second gear 16 is rotatably installed at the other end of the rotating cylinder 9, and the interior of the second gear 16 is hollow. A rotating disk 13 is fixedly installed at the end of the second gear 16. A symmetrically arranged sliding seat 17 is fixedly installed on the milling body 3. An adjusting shaft 19 is rotatably installed inside the sliding seat 17, and a clamping block 18 is threadedly connected to the outer wall of the adjusting shaft 19. The clamping block 18 is slidably located inside the sliding seat 17. The rotating cylinder 9, the center 15, and the rotating disk 13 are all connected to the machine tool 17. Both the 3-jaw chuck 14 and the three-jaw chuck 14 in the initial state are coaxially arranged. When the automotive part shaft is fixed between the two sets of limiting components, the three-jaw chuck 14 in one set of limiting components can clamp and fix the end of the automotive part shaft. The tip 15 in the other set of limiting components, which is located inside the rotating cylinder 9, extends outward under the action of the hydraulic cylinder 10, so that the end of the tip 15 abuts against the end of the automotive part shaft, thereby fixing the automotive part shaft. When the outer surface of the automotive part shaft is finished, the tip 15 and the three-jaw chuck 14 in the limiting components at both ends of the automotive part shaft can be switched to clamp the finished end of the automotive part shaft and mill the other end. The entire automotive part shaft can be finished without manual flipping of the automotive part shaft, thus improving the processing efficiency of the automotive part shaft.
[0027] like Figure 4As shown, a first gear 12 that meshes with the second gear 16 is rotatably mounted on the upper outer wall of the fixing plate 7, and a servo motor 11 is fixedly mounted on the fixing plate 7 at a position corresponding to the first gear 12. The output end of the servo motor 11 is fixedly connected to the center position of the first gear 12. The servo motor 11 drives the first gear 12 to rotate, and the first gear 12 and the second gear 16 are in a meshing state. The first gear 12 can drive the second gear 16 to rotate, thereby driving the rotating disk 13 fixedly connected to the end of the second gear 16 to rotate.
[0028] like Figure 4 As shown, a three-jaw chuck 14 is slidably mounted on the rotating disk 13, and multiple sliding seats 17 are symmetrically distributed on both sides of the three-jaw chuck 14. The included angle between two adjacent sliding seats 17 on the same side of the three-jaw chuck 14 is no greater than 30 degrees. The clamping blocks 18 on both sides of the three-jaw chuck 14 can clamp and fix both sides of the three-jaw chuck 14 after it has been slidably adjusted to a suitable position. There are no fewer than two sliding seats 17 on the same side of the three-jaw chuck 14, and no fewer than two clamping blocks 18 on the same side of the three-jaw chuck 14 to fix the outer wall of the three-jaw chuck 14, so that the position structure of the three-jaw chuck 14 is more stable after adjustment.
[0029] like Figure 1 As shown, electric slides 4 are fixedly installed on both sides of the machine tool 1. The electric slides 4 specifically include slide rails fixedly connected to the side wall of the machine tool 1 and electric sliders fixedly connected to the lower outer wall of the protective cover 2. Under the action of the electric slides 4, the protective cover 2 can slide on the upper surface of the machine tool 1. The position of the protective cover 2 can be moved according to the change of the machining point of the automotive parts shaft, so as to shield the metal scraps generated during the machining of the automotive parts shaft.
[0030] like Figure 1 As shown, blowers are fixedly installed on the lower ends of the inner walls on both sides of the protective cover 2, and dust collection troughs 5 are opened on both sides of the upper surface of the machine tool 1 to cooperate with the blowers. The blowers are located inside the protective cover 2 at an angle, and the wind speed of the angled blowers can be adjusted to blow the metal scraps and other debris accumulated below the milling body 3 into the dust collection troughs 5 for collection. The blowers located at diagonal positions are used in conjunction with the dust collection troughs 5.
[0031] The working principle of this utility model is as follows: In use, the automobile part shaft to be processed is fixed by the limiting components set at both ends of the upper surface of the machine tool 1. The milling body 3 set on the upper surface of the machine tool 1 can process the automobile part shaft. The milling body 3 in this device is a common existing technology and will not be described in detail here. The automobile part shaft is placed in front of the two sets of limiting components. The user can adjust the length of the two electric telescopic rods 8 according to the length of the automobile part shaft, thereby fixing the automobile part shaft between the two sets of limiting components. The three-jaw chuck 14 in one of the limiting components can process the automobile part shaft. The end of the shaft is clamped and fixed. In another set of limiting components, the tip 15, located inside the rotating cylinder 9, extends outward under the action of the hydraulic cylinder 10, causing the end of the tip 15 to abut against the end of the automotive part shaft, thus fixing the shaft. When the outer surface of the automotive part shaft is machined, the tip 15 and the three-jaw chuck 14 in the limiting components at both ends of the shaft can be switched to clamp the machined end of the shaft and mill the other end. This allows the entire automotive part shaft to be machined without manual rotation. After processing is completed, to improve the processing efficiency of automotive parts shafts, when processing eccentric shafts in automotive parts, the user needs to adjust the position of the three-jaw chuck 14 so that the three-jaw chuck 14, which is originally coaxial with the rotating disk 13, is eccentric. The degree of adjustment of the three-jaw chuck 14 is determined according to the degree of eccentricity at the end of the eccentric automotive part shaft, thereby facilitating the clamping of the eccentric end of the automotive part shaft by the three-jaw chuck 14. The user can adjust the position of the clamping block 18 by rotating the adjusting shaft 19. The adjusting shaft 19 specifically includes two parts: a knob and a threaded rod. The threaded rod included in the adjusting shaft 19... The sliding seat 17 rotates inside the sliding seat 17, and the clamping block 18 is rotatably connected to the threaded rod. When the adjusting shaft 19 rotates, the clamping block 18 slides inside the sliding seat 17. The clamping blocks 18 located on both sides of the three-jaw chuck 14 can clamp and fix both sides of the three-jaw chuck 14 after sliding and adjusting to a suitable position. At least two sliding seats 17 are provided on the same side of the three-jaw chuck 14, and at least two clamping blocks 18 are provided on the same side of the three-jaw chuck 14 to fix the outer wall of the three-jaw chuck 14, so that the position structure of the three-jaw chuck 14 is more stable after adjustment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
