Description

Technical Field

[0001] This utility model relates to the field of boring tool technology, specifically a high-strength boring tool. Background Technology

[0002] Existing high-strength boring tools typically consist of a tool spindle, a tool head, and a cutting section. The tool spindle is generally designed with a straight or simple flow channel structure to provide cutting stability. Coolant supply usually relies on an external coolant pump piping system, supplying coolant to the tool's working area through external connectors. In some traditional designs, coolant is delivered to the tool head through the internal flow channels of the tool spindle; however, this design often suffers from uneven coolant flow and unsatisfactory cooling effects. Furthermore, the connection between the tool spindle and the tool head is usually fixed, which can lead to connection instability due to severe vibrations and high temperatures during machining, reducing tool durability and machining accuracy.

[0003] In traditional tool designs, the distribution and cooling effect of coolant channels are uneven, often failing to meet the high heat dissipation requirements of high-intensity boring processes. This leads to excessively high tool surface temperatures, affecting machining accuracy and tool life. Under high-load operation, tools are prone to overheating, accelerating wear and impacting cutting quality. In traditional techniques, the tool spindle and tool holder are typically fixed structures, which can lead to structural instability and significant vibration during high-intensity machining. With prolonged use, the tool wears rapidly, affecting machining accuracy and increasing maintenance costs. Frequent tool replacement and repair due to rapid wear result in decreased production efficiency.

[0004] In view of this, we will study and improve the existing problems to provide a high-strength boring tool to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] A high-strength boring tool includes a tool shaft and a fixed-rotation ring. One end of the tool shaft is connected to a tool head rod. The inner side of the tool shaft is provided with an inner flow channel, and the surface of the tool shaft is provided with a swirling groove communicating with the end of the inner flow channel. The fixed-rotation ring is rotatably sleeved on the surface of the tool shaft and is correspondingly connected to the surface of the swirling groove. One end of the inner flow channel passes through the tool head rod and faces the tool surface.

[0007] By adopting the above technical solution, and by designing a spiral flow channel and vortex groove inside the tool shaft, the coolant can flow more effectively to the working area of ​​the tool, optimizing the cooling effect, reducing the heat generated by the tool during high-intensity boring, improving the stability of the tool, and ensuring high-precision machining.

[0008] In a preferred embodiment, the present invention can be further configured such that: the tool shaft and the tool head rod are integrally formed, and a tool and a pressure head screw are detachably installed on one side of the tool shaft, and one end of the pressure head screw is pressed against the surface of the tool for positioning and fixing the tool.

[0009] By adopting the above technical solutions and using an integrated molding structure design, the rigidity and stability of the cutting tool are enhanced; while the detachable cutting tool and pressure head screw design makes it easier to maintain and replace the cutting tool, improving ease of use and extending its service life.

[0010] In a preferred embodiment, the present invention can be further configured such that: the surface of the fixed swirl ring is provided with a connector pipe for connecting the coolant pump pipeline, and the surface of the cutter shaft is provided with a dynamic sealing ring adapted to the fixed swirl ring, and the dynamic sealing ring is located on the outer periphery of the swirl groove.

[0011] By adopting the above technical solution, a dynamic sealing ring is provided on the surface of the tool, which can effectively prevent coolant leakage and ensure that the coolant is accurately delivered to the working area through the connector pipe, thereby further improving the cooling effect and machining stability of the tool.

[0012] In a preferred embodiment, the present invention can be further configured such that the inner flow channel is spiral-shaped, and the number of inner flow channels is several and they are evenly distributed in a circumferential direction along the axis of the tool shaft.

[0013] By adopting the above technical solution, the spiral flow channel design can provide a more uniform coolant flow during boring, reduce the risk of local overheating of the tool, and promote the effective distribution of coolant, thereby improving cooling efficiency.

[0014] In a preferred embodiment, the present invention can be further configured such that: the surface of the vortex groove is provided with a porous structure for communicating with the ends of each inner flow channel, thereby enhancing the distribution efficiency of the coolant and ensuring that the tool can maintain good heat dissipation performance under high load.

[0015] By adopting the above technical solution, the porous structure design allows the coolant to be distributed more evenly to all cutting areas of the tool, thereby improving heat dissipation efficiency, ensuring the temperature control effect of the tool in high-intensity machining, and improving cutting performance and machining accuracy.

[0016] In a preferred embodiment, the present invention can be further configured such that the cutting tool and the pressure head screw are made of high wear-resistant alloy steel, which can effectively reduce tool wear and ensure machining accuracy over a long period of time.

[0017] By adopting the above technical solution, using high wear-resistant alloy steel components for the cutting tools and pressure head screws, wear during high-intensity machining can be effectively resisted, extending the tool's service life and maintaining high machining accuracy during long-term use, thus reducing the frequency of tool replacement.

[0018] The beneficial effects achieved by this utility model are as follows:

[0019] 1. In this utility model, by providing a spiral flow channel and a swirling groove inside the tool shaft, the coolant can be effectively guided to the tool working area, improving the cooling effect and reducing the overheating problem of the tool during high-intensity boring, thus ensuring the stability of the tool and the machining accuracy.

[0020] 2. In this utility model, by adopting an integral molding structure for the tool shaft and the tool head rod, and cooperating with a detachable and installable high wear-resistant alloy steel component tool and pressure head screw, the structural stability and wear resistance of the tool are improved, thereby extending the service life of the tool and reducing the maintenance frequency, and ensuring the machining accuracy during long-term use.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following is in conjunction with the appendix Figures 1-3 This invention describes a high-strength boring tool provided by some embodiments of the present invention.

[0029] A high-strength boring tool includes a tool shaft 100 and a fixed-rotation ring 200. One end of the tool shaft 100 is connected to a tool head rod 110. The inner side of the tool shaft 100 is provided with an inner flow channel 300, and the surface of the tool shaft 100 is provided with a swirl groove 310 communicating with the end of the inner flow channel 300. The fixed-rotation ring 200 is rotatably sleeved on the surface of the tool shaft 100 and is correspondingly connected to the surface of the swirl groove 310. One end of the inner flow channel 300 passes through the tool head rod 110 and faces the surface of the tool 120.

[0030] In this embodiment, the flow channel design of the swirl groove 310 between the tool shaft 100 and the fixed swirl ring 200 effectively guides the coolant, ensuring that the working area of ​​the tool can maintain proper cooling during high-load boring, preventing thermal damage to the tool due to excessive temperature. Furthermore, the spiral flow channel 300 design within the tool shaft 100 not only helps improve the flow efficiency of the coolant but also reduces heat accumulation on the tool surface, extending the tool's service life.

[0031] In this embodiment, the tool shaft 100 and the tool head rod 110 are integrally formed, and a tool 120 and a pressure head screw 111 are detachably installed on one side of the tool shaft 100. One end of the pressure head screw 111 is pressed against the surface of the tool 120 for positioning and fixing the tool 120.

[0032] In this embodiment, the tool shaft 100 and the tool head shank 110 adopt an integral molding structure, which increases the overall rigidity and effectively improves the stability of the tool. In high-intensity working environments, tool deformation and vibration are controlled, ensuring machining accuracy. Furthermore, the tool 120 and the pressure head screw 111 are detachable, allowing operators to easily replace different specifications of tool heads according to actual needs, greatly improving flexibility, reducing downtime, and increasing production efficiency.

[0033] In this embodiment, the surface of the fixed swirl ring 200 is provided with a connector pipe 210 for connecting the coolant pump pipeline, and the surface of the cutter shaft 100 is provided with a dynamic sealing ring adapted to the fixed swirl ring 200, and the dynamic sealing ring is located on the outer periphery of the swirl groove 310.

[0034] This embodiment effectively prevents coolant leakage by incorporating a dynamic sealing ring between the tool shaft 100 and the fixed-rotation ring 200. The sealing ring not only improves the tool's sealing performance but also ensures precise delivery of coolant to the inner flow channel 300, enhancing cooling efficiency and guaranteeing tool stability under high loads. The outer circumference of the sealing ring ensures it does not experience excessive wear during operation, effectively extending the tool's service life.

[0035] In this embodiment, the inner flow channels 300 are spiral-shaped, and there are several inner flow channels 300, which are evenly distributed circumferentially along the axis of the tool shaft 100. In this embodiment, the spiral shape and even distribution of the inner flow channels 300 along the axis of the tool shaft 100 allow the coolant to flow more uniformly within the tool shaft, further improving the cooling effect. This design significantly reduces localized overheating, better protects the tool surface, and enhances the tool's durability and machining accuracy during processing.
