Description

Technical Field

[0001] This utility model belongs to the technical field of CNC machine tools, specifically relating to a turning-milling composite turret tool post. Background Technology

[0002] The milling-turning turret is one of the core components of modern CNC machine tools. Originating in the late 20th century, the manufacturing industry's demand for efficient and precise machining increased. With the increasing requirements for integrated machining of complex parts in aerospace, automotive and other fields, traditional single-function turrets could no longer meet the needs of multi-process integration, prompting the development of turret turrets that combine turning and milling functions. Through a high-rigidity turret structure, multi-station automatic tool changer system and CNC precision control, this type of turret achieves seamless switching between turning and milling processes, significantly reducing the number of clamping operations and auxiliary time, and has become an important technological extension of five-axis linkage machining centers.

[0003] Currently, the bearing seals of milling and turning turret tool holders may develop tiny gaps after long-term use due to aging or condensation buildup inside the turret, allowing coolant to gradually seep into the bearing. Initially, the seepage is small, and the bearing can still operate normally without significant temperature rise or abnormal noise. However, the mixture of coolant and grease reduces lubrication performance and slowly corrodes the bearing raceways and cage. This problem is highly insidious and is often only discovered when the bearing exhibits obvious jamming or noise; by then, irreversible wear has occurred, requiring replacement of the entire bearing assembly.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a milling-turning turret tool holder, comprising:

[0032] The support mechanism 100 includes a support base 110, a guide rail 120 fixedly installed on the top of the support base 110, and a positioning assembly 130 disposed on the outside of the guide rail 120 for placing the processing parts.

[0033] The adsorption mechanism 200 includes a base 210, a drying assembly 220 disposed in the inner cavity of the base 210, a sealing seat 230 fixedly installed on the top of the base 210, a drainage surface 240 formed on the inner wall of the opening of the sealing seat 230, a drainage groove 250 formed on the bottom of the sealing seat 230, and a support seat 260 fixedly installed in the inner cavity of the sealing seat 230.

[0034] The rigid connection between the support seat 110 and the guide rail 120 ensures the overall load-bearing stability of the tool holder. Meanwhile, the positioning component 130 enables rapid positioning and fixing of the machined parts, effectively improving clamping efficiency. The precision guiding characteristics of the guide rail 120 reduce vibration during movement, ensuring machining accuracy, making it particularly suitable for high-precision milling and turning machining scenarios. The coordinated cooperation between the sealing seat 230 and the support seat 260 forms a closed protective structure, preventing coolant from entering critical components. The combined design of the drainage surface 240 and the drainage groove 250 actively guides the directional flow of the infiltrated liquid, avoiding local accumulation, significantly extending the service life of precision components such as bearings, and reducing maintenance frequency.

[0035] Specifically, the adsorption mechanism 200 also includes a sealing ring 270 fixedly installed on the top of the support 260, a drainage channel 280 opened in the inner cavity of the platform 210, and an inclined surface 290 opened in the inner wall of the drainage channel 280.

[0036] The sealing ring 270 and the support base 260 form a double sealing barrier, which further improves the anti-permeability performance. The inclined structure of the inner slope 290 of the drainage channel 280 can accelerate the liquid discharge and prevent backflow. Its self-cleaning characteristics reduce the risk of impurity accumulation and ensure long-term reliable operation.

[0037] Furthermore, the drying assembly 220 includes a box 221 movably placed inside the cavity of the base 210, a pressing seal 222 disposed on the top of the box 221, a cavity 223 opened inside the cavity of the box 221, an isolation plate 224 fixedly installed inside the cavity 223, a drying adsorption plate 225 movably placed outside the isolation plate 224, and a connecting surface 226 disposed inside the cavity of the box 221 and having the same inclination angle as the inclined surface 290.

[0038] The box body 221 and the downward sealing element 222 constitute a detachable drying unit, which is convenient for maintenance and replacement. The inclined arrangement of the isolation plate 224 forms a multi-level adsorption space, which maximizes the contact area between the drying adsorption plate 225 and the liquid, thereby improving the moisture absorption efficiency. The matching design of the connecting surface 226 and the inclined surface 290 optimizes the liquid flow path and achieves efficient dehumidification. The cover plate 2221 provides continuous downward pressure through the spring 2222, which ensures that the sealing plate 2224 and the opening of the box body 221 fit tightly and prevents external liquid from seeping in. The mechanical limiting function of the limiting groove block 2223 avoids sealing failure. Its modular design facilitates quick inspection and maintenance, significantly improving maintenance convenience.

[0039] Preferably, the positioning assembly 130 includes a base 131 movably sleeved on the outside of the guide rail 120, an adjusting lever 132 hinged on the outside of the base 131, a toothed block 133 fixedly connected to the rotating end of the adjusting lever 132, and a rack sliding column 134 meshing with the toothed block 133 and movably locked in the inner cavity of the base 131.

[0040] The adjusting lever 132 achieves fine-tuning and positioning of the machine base 131 through the meshing transmission between the toothed block 133 and the rack sliding column 134. Its mechanical self-locking characteristic can prevent displacement during the processing and ensure the accuracy of the processing position. This structure is easy to operate and is suitable for processing conditions with frequent adjustments.

[0041] It should be noted that there are nine isolation plates 224, which are arranged at an angle to form a space for directly placing the drying adsorption plate 225.

[0042] The stepped, inclined arrangement of the nine isolation plates 224 forms a uniformly distributed accommodating space, which effectively improves the adsorption efficiency of the drying adsorption plate 225. This layout also optimizes the airflow channel, avoids local saturation, extends the replacement cycle of the adsorption material, and reduces operating costs.

[0043] Furthermore, the bearing mechanism 100 also includes a bearing housing 140 and a rotating assembly 150 disposed on the top of the bearing housing 140. The rotating assembly 150 includes a tool holder 151, a mounting base 152 fixedly mounted on the outside of the tool holder 151, and a mounting bushing 153 fixedly mounted on the outside of the mounting base 152 for adapting to the mounting of various tools.

[0044] The rigid connection structure between the tool holder 151 and the mounting base 152 ensures the stability of tool installation. The standardized interface design of the mounting bushing 153 is compatible with the quick change of various tools, meeting the multi-process requirements of composite machining. Its overall structure has been optimized by dynamic balancing, which can adapt to high-speed rotation conditions and reduce the impact of vibration on machining quality.

[0045] During use, the operator drives the rack sliding column 134 to move via the adjusting lever 132 of the positioning component 130 to quickly position the workpiece. During the cutting process, the sealing seat 230 and the sealing ring 270 prevent external liquid from entering, and the trace amount of liquid that seeps in is guided to the drainage groove 250 through the drainage surface 240 and the inclined surface 290 for discharge. The drying component 220 continuously absorbs moisture through the drying adsorption plates 225 arranged in layers by the isolation plate 224, and the spring 2222 of the pressing seal 222 dynamically maintains the sealing state of the box 221. The tool can be quickly replaced by the mounting bushing 153, and the tool holder 151 rotates stably under the support of the bearing seat 140 to complete multi-process composite processing. All functional units work together to ensure high-precision processing and long-term protection of the equipment.

[0046] In summary, the collaborative design of the support mechanism 100 and the adsorption mechanism 200 achieves the dual advantages of high-precision machining and long-term protection. The rigid connection between the support seat 110 and the guide rail 120 ensures the overall structural stability, and the quick clamping function of the positioning component 130 significantly improves machining efficiency. The adsorption mechanism 200 effectively isolates coolant and moisture through multiple protections such as the sealing seat 230, the drainage surface 240, and the drying component 220, extending the life of key components. The dynamic balance design of the rotating component 150 supports high-speed cutting, while the modular drying unit and standardized tool interface greatly reduce maintenance costs. The overall solution combines machining accuracy, reliability, and ease of operation.

[0047] Example 2

[0048] Reference Figure 1 , Figure 2 and Figure 6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a pressure sealing member 222 for effectively sealing the opening of the box 221.

[0049] Specifically, the pressure sealing element 222 includes a cover plate 2221 hinged to the top of the box body 221, a spring 2222 fixedly installed at the bottom of the cover plate 2221, a limiting groove block 2223 fixedly installed at the bottom of the cover plate 2221, and a sealing plate 2224 fixedly installed at the bottom of the limiting groove block 2223. The bottom of the sealing plate 2224 is movably engaged with the opening at the top of the box body 221.

[0050] The downward sealing element 222 achieves rapid opening and closing through the hinge structure between the cover plate 2221 and the box body 221. The continuous elastic force provided by the spring 2222 ensures that the sealing plate 2224 and the opening of the box body maintain a constant clamping force, forming a reliable dynamic seal. The rigid limiting function of the limiting groove block 2223 can prevent the sealing plate 2224 from being over-compressed and deformed, while its precision snap-fit ​​structure with the opening of the box body 221 allows for slight floating compensation while ensuring sealing performance, effectively adapting to dimensional fluctuations caused by temperature changes. This structure combines the reliability of mechanical seals with the adaptability of elastic seals, maintaining stable anti-leakage performance during long-term use, and facilitating maintenance operations such as desiccant replacement by lifting the cover plate 2221, significantly improving the maintainability and service life of the equipment.

[0051] In use, the operator first opens the sealing assembly as a whole through the hinged cover plate 2221; when sealing is required, the cover plate 2221 is pressed down, causing the spring 2222 to compress, while the limiting groove block 2223 guides the sealing plate 2224 to accurately align with the opening of the box body 221; during the closing process, the elastic force of the spring 2222 continuously acts on the sealing plate 2224, making it form a tight elastic contact seal with the opening of the box body 221; the rigid structure of the limiting groove block 2223 ensures that the sealing plate 2224 will not be excessively pressed down, while allowing slight floating to adapt to vibration and temperature changes during processing; the movable snap-fit ​​structure at the bottom of the sealing plate 2224 maintains the sealing performance while facilitating quick disassembly and reinstallation during regular maintenance.

[0052] In summary, the hinged cover 2221 enables convenient opening and closing, the spring 2222 provides continuous downward pressure to ensure that the sealing plate 2224 fits tightly against the opening of the box 221, and the limiting groove 2223 ensures that the sealing plate 2224 is accurately positioned, forming a reliable dynamic sealing structure that can effectively prevent liquid from seeping in and facilitate maintenance.
