Description

Technical Field

[0001] This utility model relates to an auxiliary processing support structure. Background Technology

[0002] The bicycle hub is a core component of the wheelset, and its machining precision directly affects the smoothness of wheel rotation, load-bearing capacity, and lifespan. Traditional hub manufacturing primarily relied on general-purpose lathes and manual operation. However, with the bicycle industry's increasing demands for lightweight, high-strength, and high-precision components, modern hub manufacturing has gradually shifted to high-precision CNC lathes and mill-turn machining centers to meet complex structures and stringent process requirements. During hub machining, a top support and rotating mechanism are used to enlarge the hub's bore. However, conventional top supports are integrally molded with the lathe's auxiliary parts and lack a detachable structure. This means that in subsequent use, the top support may wear out and fail to achieve the required precision. Therefore, the inventor specifically designed a structure that allows for easy disassembly of the top support, facilitating subsequent replacement. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0021] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Reference Figure 1-4 As shown, an auxiliary processing support structure includes...

[0023] Lathe body 10; the lathe body 10 is provided with a door 20 and a storage device 30 located at the front end of the lathe body 10.

[0024] An auxiliary machining part 40 is provided inside one side of the lathe body 10; a front protruding ring 400 is provided at one end of the auxiliary machining part 40; and an inner ring 4002 is provided inside the front protruding ring 400. Bolt holes 4004 for connecting with the first bolt 5060 are formed at both ends of the inner ring 4002; and a plurality of water leakage holes 4006 are formed on the outer wall of the front protruding ring 400.

[0025] In one embodiment, the drainage holes 4006 of the front convex ring 400 can be changed to an inclined spiral arrangement, using centrifugal force to guide the coolant to form a swirling flow, thereby enhancing the debris flushing efficiency; the holes are embedded with removable filters (pore size graded) to avoid large particles from clogging.

[0026] The top support mechanism 50, which is connected in conjunction with the auxiliary processing part 40, is used for processing the flower drum. The top support mechanism 50 includes a column 500, an L-shaped groove 502 formed on the outer wall of the column 500, a top rod 504 connected to the column 500, a receiving ring 506 and a barrier net 508 sleeved on the top rod 504, first bolts 5060 symmetrically arranged at both ends of the receiving ring 506, and a fixing member arranged between the column 500 and the top rod 504. The fixing member includes a mounting ring 510, an extension plate 5100 surrounding the outer wall of the mounting ring 510, and a second bolt 5102 arranged on the extension plate 5100. A blocking rod 5104 for blocking the L-shaped groove 502 is symmetrically arranged at one end of the mounting ring 510.

[0027] Specifically, the barrier net 508 is made of shape memory alloy.

[0028] In one embodiment, to better secure the push rod 504, an electromagnet (low-power design) is embedded within the column 500, in addition to the mechanical engagement between the L-shaped groove 502 and the clamping rod 5040. When the push rod 504 rotates into position, it automatically attracts the clamping rod 5040, achieving double fixation (mechanical + magnetic force) to prevent loosening caused by machining vibration. During replacement, the magnetism is released by disconnecting the power, retaining the convenience of manual disassembly. Furthermore, a hard chrome plating layer is applied to the surface of the push rod 504 to extend its lifespan, and a miniature pressure sensor is integrated at the base of the clamping rod 5040. This sensor monitors the stress state of the push rod 504 in real time via wireless transmission. When wear exceeds a threshold, the lathe control system alarms to prompt replacement.

[0029] A locking rod 5040 is provided on the outer wall of one end of the top rod 504; the top rod 504 is inserted into the column 500 and rotated, and the locking rod 5040 is locked and fixed with the L-shaped groove 502; a first notch 5062 is formed on both the receiving ring 506 and the barrier net 508; a groove is formed at one end of the blocking rod 5104, and a spring 51040 is provided inside the groove. An abutment 51042 is provided at one end of the spring 51040, an arc-shaped opening 51044 is formed at the end of the abutment 51042, and an arc-shaped part 51046 is formed at the edge of the end of the abutment 51042.

[0030] In one embodiment, the abutment 51042 of the plug rod 5104 can be upgraded to a piezoelectric ceramic drive. The preload of the spring 51040 is dynamically adjusted by detecting the wear of the L-shaped groove 502 (replacing the passive spring force) to ensure that it can still fit tightly against the groove wall after long-term use. At the same time, an ultrasonic generator (intermittent operation) is integrated inside the plug rod 5104 to prevent debris from getting stuck in the arc-shaped opening 51044 and affecting the sealing performance.

[0031] Furthermore, the arc-shaped opening 51044 can be designed as a "segmented floating structure" consisting of 3 to 4 independent arc-shaped blocks. Each block has a micro hydraulic cavity behind it, which automatically adjusts the curvature and fit according to the wear of the L-shaped groove 502. At the same time, a self-healing material containing microcapsules (such as polyurethane-based + epoxy resin) is sprayed on the arc part 51046. After wear, the repair agent is released to fill the scratches.

[0032] Working principle: The auxiliary machining part 40 on the lathe body 10 is connected to the top support mechanism 50 through the front protruding ring 400 and the inner ring 4002. The column 500 of the top support mechanism 50 cooperates with the retaining rod 5040 at the end of the push rod 504 through the L-shaped groove 502, realizing the quick installation and disassembly of the push rod 504, which is convenient for replacement after wear. The push rod 504 supports the receiving ring 506 and the barrier net 508 (both of which are provided with the first notch 5062) to fix the workpiece. At the same time, the front protruding ring 40... The drain hole 4006 on the 0 can drain coolant or machining debris; the fastener is fixed to the overall structure by the second bolt 5102 through the mounting ring 510 and the extension plate 5100. The plug rod 5104 pushes the abutment 51042 under the elastic force of the spring 51040, so that its arc-shaped opening 51044 and arc part 51046 are tightly fitted into the L-shaped groove 502, ensuring the stability of the top rod 504 after installation, thereby achieving efficient machining support and debris removal for workpieces such as hubs.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
