Description

Technical Field

[0001] This utility model relates to the field of machining tools, and in particular to a high-precision reamer for machining steering gears. Background Technology

[0002] A reamer is a tool used for cutting and machining materials, commonly used in industrial and mechanical fields. It typically consists of a cutter head with multiple cutting edges and a rotating shaft. The shape and cutting edge design of the cutter head can be adjusted according to different application requirements. It processes materials by rotating and cutting. When rotating, the cutting edge of the cutter head cuts into the material, thereby removing the material. It is widely used for processing various materials, including metals, plastics, wood, etc., especially in cases requiring fine machining or complex shapes.

[0003] When existing reamers are connected to machine tools, the connection end between their spindle and the tool holder adapter is close to the machine tool spindle. This results in a long overhang of the tool tip and a large tension on the spindle, which makes the tool prone to runout during machining, making it difficult to ensure the stability of the machining dimensions and thus affecting the machining accuracy.

Attached Figure Description

[0013] Figure 1 This is a structural schematic diagram of the main view of a high-precision reamer used for machining steering gears.

[0014] The components in the attached diagram are labeled as follows: 1. Tool head; 2. Tool holder adapter; 3. Cutting edge; 4. Shaft; 5. First flange; 6. Second flange; 7. Extension section; 8. Cooling channel; 9. Support channel. Detailed Implementation

[0015] The preferred embodiments of the present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] according to Figure 1 A high-precision reamer for machining steering gears includes a cutter head 1 and a tool holder adapter 2. The cutter head 1 is connected to the tool holder adapter 2 via a rotating shaft 4. The top of the cutter head 1 is provided with a plurality of cutting edges 3. The rotating shaft 4 is provided with a cutting stabilizing structure, which can reduce tool runout during machining, ensure the stability of machining dimensions, and improve machining accuracy.

[0017] The cutting stabilization structure includes an anti-shake structure to reduce tool runout during machining and a cooling structure to improve tool machining accuracy.

[0018] The anti-shake structure includes a first flange 5, a second flange 6, and an extension section 7. The first flange 5 is located at the right end of the rotating shaft 4, and the second flange 6 is connected to the tool holder adapter 2. The first flange 5 and the second flange 6 cooperate to connect the rotating shaft 4 and the tool holder adapter 2.

[0019] An extension section 7 is provided between the second flange 6 and the tool holder adapter 2. In the original structure, the connection end of the rotating shaft 4 and the tool holder adapter 2 is close to the machine tool spindle, which results in a long overhang of the front end of the tool head 1 and a large tension on the spindle. This causes the tool to easily run out of space during machining, making it difficult to ensure the stability of the machining dimensions and thus affecting the machining accuracy.

[0020] The first flange 5, the second flange 6, and the extension section 7 cooperate to bring the connection end of the rotating shaft 4 and the tool holder adapter 2 closer to the cutter head 1 without changing the length from the cutter head 1 to the tool holder adapter 2. This reduces the spindle load, reduces tool runout during machining, and ensures stable machining dimensions.

[0021] The cooling structure includes a cooling channel 8, which passes through the tool head 1, the rotating shaft 4, the extension section 7 and the tool holder adapter 2, and is connected to an external coolant delivery device through a connection hole on the machine tool spindle. The cooling channel 8 is used to deliver the coolant from the external coolant delivery device to the tool.

[0022] The cooling channel 8 is provided with a plurality of branch channels 9 opposite to the external coolant delivery device. Each of the branch channels 9 corresponds to a plurality of cutting edges 3. A coolant outlet is provided near the cutting edge 3 and is connected to the corresponding branch channel 9. The coolant outlet guides the coolant in the cooling channel 8 to the corresponding cutting edge 3 through the branch channel 9 to cool it down. This prevents the tool material from becoming too hard due to excessive temperature, reduces wear, and increases the tool's service life. At the same time, it prevents the workpiece from becoming too hot due to excessive temperature and ensures machining accuracy.

[0023] In this embodiment, the tool holder adapter 2 is model HSK 63A-FL80-200.

[0024] Compared with the prior art, the present invention provides a high-precision reamer for steering gear machining. The reamer adopts a cutting stability structure, which can reduce tool runout during machining, ensure the stability of machining dimensions, and improve machining accuracy.
