Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a wheel hub processing anti-sway fixing structure. Background Art

[0002] The wheel hub is the core component of a car tire, typically consisting of spokes and a center section. It connects the tire to the vehicle's axle, bearing the vehicle's weight and transmitting power. During wheel hub machining, a fixed structure is required to position the hub and prevent it from wobbling during machining, thereby ensuring machining accuracy and wheel quality.

[0003] For example, a wheel hub processing anti-sway fixing structure with announcement number CN220761703U includes a wheel hub body and a fixed base plate. The fixed base plate is located directly below the spokes of the wheel hub body. The fixed base plate is fixed with multiple support blocks directly below the bottom edge of the rim of the wheel hub body. The bottom surface of the bottom edge of the rim of the wheel hub body is pressed against the top surface of the corresponding support block; it clamps the bottom edge of the rim of the wheel hub body so that it is firmly clamped, and the bottom edge of the rim of the wheel hub body is not easy to deform after the thickness is reduced, thereby ensuring the accuracy of subsequent processing.

[0004] The above patent proposes clamping the bottom edge of the rim of the hub body so that it is firmly clamped. However, during the hub processing process, since the central area of ​​the hub is subjected to greater vibration, if the central area of ​​the hub is not supported, the hub will be deformed or deflected during processing, affecting the processing results.

[0005] Therefore, we propose a wheel hub processing anti-sway fixing structure to solve the above-mentioned problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A wheel hub machining anti-sway fixing structure includes a machining base 1 and a wheel hub structure 2 arranged on the upper end of the machining base 1. The upper end of the machining base 1 is further provided with a fixing member 4 for fixing the wheel hub structure 2. The upper end of the machining base 1 is provided with a supporting and positioning member 3 for supporting and positioning the central area of ​​the wheel hub structure 2, which can provide additional support for the wheel hub structure 2 and ensure that the wheel hub structure 2 remains stable during machining;

[0024] The supporting and positioning component 3 includes a central support tube 31 and a cylinder part 32 arranged at the upper end of the processing base 1. The cylinder part 32 is placed on the outside of the central support tube 31. The telescopic end of the cylinder part 32 is connected to a fixed block 33. A limiting ring 34 is provided on the inner side of the fixed block 33. An internal support part 35 is also provided on the surface of the processing base 1. The center of the hub structure 2 is placed on the central support tube 31. The internal support part 35 is used to provide internal support to the center of the hub structure 2. When the cylinder part 32 is started, the fixed block 33 and the limiting ring 34 can be pushed to move. The limiting ring 34 can limit the center of the hub structure 2 to achieve restriction of the hub structure 2.

[0025] The inner support member 35 includes a slide groove 351 opened on the surface of the processing base 1 and a screw rod 352 arranged inside the slide groove 351. The screw rod 352 is externally connected to the output end of the motor. A threaded seat 353 is provided on the outer side of the screw rod 352. An inner limit plate 354 is provided on the upper end of the threaded seat 353. When the motor is started, the screw rod 352 can be driven to rotate, and the inner limit plate 354 can be moved toward the direction close to the hub structure 2 under the drive of the threaded seat 353.

[0026] Four groups of inner support members 35 are provided, and the four groups of inner support members 35 are symmetrically distributed on the processing base 1 in pairs, so that the clamping force on the hub structure 2 is evenly distributed, thereby reducing the deformation of the hub structure 2 during the processing.

[0027] The fixing component 4 includes a fixing seat 41 arranged at the upper end of the processing base 1 and an electric push rod 42 arranged on the outer wall of the fixing seat 41. The telescopic end of the electric push rod 42 is connected to a connecting seat 43. The connecting seat 43 is provided with an outer limit plate 44 for clamping the hub structure 2 on the side away from the electric push rod 42. When the electric push rod 42 is started, it can push the connecting seat 43 and the outer limit plate 44 to move, so as to clamp the outer wall of the hub structure 2.

[0028] In this embodiment: the hub structure 2 is placed on the central support tube 31, and then the cylinder 32 is started to push the fixed block 33 and the limit ring 34 to move until the limit ring 34 contacts the central outer wall of the hub structure 2, which can limit it. At the same time, the motor is started to drive the screw rod 352 to rotate. Driven by the threaded seat 353, the inner limit plate 354 can move in the direction close to the hub structure 2, which can provide internal support to the center of the hub structure 2, thereby realizing support and limitation of the central area of ​​the hub structure 2. The electric push rod 42 is started to push the connecting seat 43 and the outer limit plate 44 to move, which can clamp the outer wall of the hub structure 2, thereby limiting the inside and outside of the hub structure 2, so that the hub structure 2 has a better fixing effect and prevents swaying. The inner limit plate 354 and the outer limit plate 44 are evenly distributed on the inner and outer walls of the hub structure 2, so that the hub structure 2 is evenly stressed, thereby reducing the deformation of the hub structure 2 during processing.

[0029] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 4 The fixing member 4 also includes an articulated seat 45 arranged at the upper end of the connecting seat 43 and a micro motor 46 arranged on the outside of the articulated seat 45. There are two groups of articulated seats 45, which are respectively installed on the two groups of connecting seats 43. The two groups of articulated seats 45 are symmetrically distributed. The inner side of the articulated seat 45 is rotatably connected to the lower pressure plate 47. The output end of the micro motor 46 is connected to the lower pressure plate 47. When the micro motor 46 is started, the lower pressure plate 47 can be driven to rotate, which can achieve the purpose of tightening the hub structure 2.

[0030] A number of sawtooth protrusions 471 are evenly distributed on the side wall of the lower pressing plate 47 . The setting of the sawtooth protrusions 471 is used to increase the friction between the lower pressing plate 47 and the hub structure 2 and reduce the sliding between the lower pressing plate 47 and the hub structure 2 .

[0031] In this embodiment: after the hub structure 2 is fixed, the micro motor 46 is started to drive the lower pressure plate 47 to rotate, which can press the hub structure 2, and the fixing effect is good, which is beneficial to the processing of the hub structure 2. At this time, the serrated protrusion 471 can contact the surface of the hub structure 2, which can increase the contact friction between the two, thereby reducing the sliding between the lower pressure plate 47 and the hub structure 2.

[0032] Working principle: Place the hub structure 2 on the central support tube 31, and then start the cylinder 32 to push the fixed block 33 and the limit ring 34 to move until the limit ring 34 contacts the outer wall of the center of the hub structure 2, which can limit it. At the same time, start the motor to drive the screw rod 352 to rotate. Driven by the threaded seat 353, the inner limit plate 354 can move toward the direction close to the hub structure 2, which can provide internal support to the center of the hub structure 2, and start the electric push rod 42 to push the connecting seat 43 and the outer limit plate 44 to move, which can clamp the outer wall of the hub structure 2, thereby limiting the inside and outside of the hub structure 2. After the hub structure 2 is fixed, start the micro motor 46 to drive the lower pressure plate 47 to rotate, which can press the hub structure 2.
