Description

Technical Field

[0001] This utility model relates to a composite chamfering tool, specifically a high-precision multi-purpose composite chamfering tool with easy-to-change tool head, belonging to the field of chamfering tool technology. Background Technology

[0002] A high-precision multi-purpose composite chamfering cutter is a tool specifically designed to meet the demands of precision machining. It combines multiple functions into one unit, enabling efficient and accurate chamfering operations of various shapes and angles. High-precision multi-purpose composite chamfering cutters are widely used in aerospace, automotive manufacturing, machinery manufacturing, and electronics industries for chamfering and deburring various precision components. For example, in the aerospace field, they are used to chamfer aircraft engine blades, turbines, and other components; in the automotive manufacturing field, they are used to chamfer automotive parts such as gears and bearings.

[0003] In the prior art, such as the composite chamfering tool disclosed in publication number CN207255273U, a tool head is included. The sidewall of the tool head has at least two cutting teeth, each tooth comprising a first cutting section and a second cutting section. The radial profile edge of the first cutting section extends outwardly from the end of the tool head to the side edge of the tool head, and the radial profile edge of the second cutting section extends inwardly from the side edge of the tool head. This tool can sequentially process both upper and lower chamfers without using two different tools, thus eliminating the time spent changing tools and improving processing efficiency. It also reduces the number of tools used, lowering tooling costs.

[0004] Although the above technical solution can process both upper and lower chamfers sequentially without using two different cutting tools, thus saving time spent on tool changing and improving processing efficiency, it is inconvenient to disassemble and replace the chamfering tool during use, resulting in poor practicality. Therefore, a high-precision multi-purpose composite chamfering tool with a convenient tool head replacement is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the problem of inconvenient disassembly and replacement of chamfering tools during use, resulting in poor applicability, by providing a high-precision multi-purpose composite chamfering tool with easily replaceable cutting heads.

[0006] The present invention achieves the above objectives through the following technical solution: a high-precision multi-purpose composite chamfering tool with convenient tool head replacement, including a chamfering tool holder, one end of which is connected to a chamfering tool head, the inner wall of which is provided with a quick-release mechanism for disassembling the tool head, and the interior of which is provided with a heat dissipation mechanism for cooling the tool head.

[0007] The quick-release mechanism includes a mounting groove, which is formed on the inner wall of the chamfered tool holder. A limit rod is installed inside the mounting groove. A movable block that slides and connects with the mounting groove is fixed on the outer surface of the limit rod. A spring sleeved on the limit rod is abutted and connected to the upper surface of the movable block.

[0008] As a further improvement of this utility model: the front end of the chamfered tool holder is connected to a connector, and the upper surface of the connector is provided with a limiting hole for insertion and connection with the limiting rod.

[0009] As a further improvement of this utility model, the outer surface of the chamfering cutter head is provided with three chip removal grooves.

[0010] As a further improvement of this utility model, a chamfered blade is installed at the front end of each of the three chip removal grooves.

[0011] As a further improvement of this utility model: the interior of the chamfering blade is fitted with an internal hexagon screw that is threadedly connected to the chamfering head.

[0012] As a further improvement of this utility model: the heat dissipation mechanism includes a liquid storage chamber, which is located inside the chamfered tool holder.

[0013] As a further improvement of this utility model: a heat-conducting ring matching the liquid storage cavity is fixed to the outer wall of the chamfered tool holder, and three heat sinks are fixed to the outer surface of the heat-conducting ring.

[0014] The beneficial effects of this utility model are: by manually pulling the limiting rod on the mounting groove, the movable block on the limiting rod drives the spring to compress. At this time, the end of the limiting rod separates from the limiting hole on the connector, releasing the fixation of the chamfering head, which makes it convenient to disassemble and replace the chamfering head.

[0015] The connecting parts can absorb the heat from the chamfering head and transfer it to the heat exchange fluid. This allows the heat-conducting ring to absorb the heat and transfer it to the heat sink. When the chamfering handle rotates, it can simultaneously drive the heat sink to rotate, allowing the heat from the heat sink to dissipate into the air, thus achieving active heat dissipation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a high-precision multi-purpose composite chamfering tool with convenient tool head replacement includes a chamfering tool holder 1, one end of which is connected to a chamfering tool head 2. The inner wall of the chamfering tool holder 1 is provided with a quick-release mechanism for disassembling the tool head, and the interior of the chamfering tool holder 1 is provided with a heat dissipation mechanism for cooling the tool head.

[0023] The quick-release mechanism includes a mounting groove 3, which is formed on the inner wall of the chamfering tool holder 1. A limit rod 31 is installed inside the mounting groove 3. A movable block 32, which slides and connects to the mounting groove 3, is fixed on the outer surface of the limit rod 31. A spring 33, which is sleeved on the limit rod 31, is abutted against the upper surface of the movable block 32. A connector 34 is inserted and connected to the front end of the chamfering tool holder 1. A limit hole 35, which is inserted and connected to the limit rod 31, is formed on the upper surface of the connector 34. Three chip removal grooves 4 are formed on the outer surface of the chamfering head 2. Each end is equipped with a chamfering blade 5. When the chamfering head 2 needs to be disassembled, the limiting rod 31 on the mounting groove 3 can be manually pulled, so that the movable block 32 on the limiting rod 31 drives the spring 33 to compress. At this time, the end of the limiting rod 31 separates from the limiting hole 35 on the connector 34, releasing the fixation of the chamfering head 2. This makes it easy to disassemble and replace the chamfering head 2. After the limiting rod 31 is released, the limiting rod 31 will be reset under the elasticity of the spring 33, thereby fixing the chamfering head 2 for easy use. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: an internal hexagon screw 6 threadedly connected to the chamfering head 2 is installed inside the chamfering blade 5; the heat dissipation mechanism includes a liquid storage chamber 7, which is opened inside the chamfering handle 1; a heat-conducting ring 71 matching the liquid storage chamber 7 is fixed on the outer wall of the chamfering handle 1; and three heat sinks 72 are fixed on the outer surface of the heat-conducting ring 71. By unscrewing the internal hexagon screw 6 on the chamfering blade 5, a single chamfering blade 5 can be disassembled and replaced without replacing the entire head, thus improving practicality. When processing the workpiece, the chamfering head 2 generates heat, and the liquid storage chamber 7 contains heat exchange fluid. The heat is absorbed by the chamfering head 2 through the connector 34 and transferred to the heat exchange fluid, allowing the heat-conducting ring 71 to absorb heat and transfer it to the heat sinks 72. When the chamfering handle 1 rotates, it can synchronously drive the heat sinks 72 to rotate, allowing the heat of the heat sinks 72 to dissipate into the air, thereby achieving active heat dissipation.

[0025] Working Principle: Before using this high-precision multi-purpose composite chamfering tool with easy-to-change tool head, first connect the chamfering tool to the output shaft of the machine tool, fix the chamfering tool holder 1 to the machine tool output shaft, so that the machine tool can drive the chamfering tool holder 1 to rotate, thereby driving the chamfering tool head 2 to chamfer the workpiece. The three chamfering inserts 5 can easily chamfer the workpiece and improve the chamfering accuracy. The waste generated during chamfering can be discharged to the outside through the chip removal groove 4 for easy use. By unscrewing the hex socket screws 6 on the chamfering inserts 5, individual chamfering inserts 5 can be disassembled and replaced without replacing the entire tool head, improving practicality. During workpiece processing, the chamfering tool head 2 generates heat, and the liquid storage chamber 7 contains heat exchange fluid, which can be transferred through the connecting piece 34. The heat exchanger absorbs the heat from the chamfering head 2 and transfers it to the heat exchange fluid. This allows the heat-conducting coil 71 to absorb the heat and transfer it to the heat sink 72. When the chamfering handle 1 rotates, it synchronously drives the heat sink 72 to rotate, allowing the heat from the heat sink 72 to dissipate into the air, thus achieving active heat dissipation. When the chamfering head 2 needs to be disassembled, the limiting rod 31 on the mounting slot 3 can be manually pulled, causing the movable block 32 on the limiting rod 31 to compress the spring 33. At this time, the end of the limiting rod 31 separates from the limiting hole 35 on the connector 34, releasing the fixation of the chamfering head 2. This facilitates the disassembly and replacement of the chamfering head 2. After releasing the limiting rod 31, the spring 33 will return to its original position under its own elasticity, thus fixing the chamfering head 2 for convenient use.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
