Description

TECHNICAL FIELD

[0001] The application relates to the technical field of deep hole machining, in particular to a deep hole machining positioning and guiding device. BACKGROUND

[0002] Deep hole machining is mainly aimed at holes with a ratio of hole depth to hole diameter greater than 6, especially the ratio L / d of hole depth to hole diameter of deep holes in specific application scenarios, such as oil cylinder holes, axial oil holes of shafts, hollow spindle holes and hydraulic valve holes.

[0003] The existing patent (publication number: CN220240130U) discloses a deep hole machining positioning and guiding device, which belongs to the technical field of machining. The device comprises a plurality of drill sleeves for accommodating drill tools, a machining clamp arranged on the end face of the workpiece or a machining hole of the workpiece close to one end of the drill sleeve, and a positioning plate assembled at the end of the drill sleeve away from the workpiece. In the case that the positioning plate is arranged in alignment with the workpiece and the positioning plate is provided with a plurality of positioning holes, the drill sleeve determines the machining axis of the drill tool by being assembled and connected to the machining hole or machining clamp of the workpiece on one side and to the positioning hole of the positioning plate on the other side. The positioning and guiding device of the present application mainly positions and guides the drill tool during deep hole machining. While ensuring the positioning accuracy of the drilling position, the device can support and guide the drill tool based on the drill sleeve structure to suppress the shaking and deflection of the drill tool during machining, thereby improving the machining accuracy of the drilling, reaming and eccentric hole machining process in cooperation with the machining clamp of the workpiece.

[0004] The above-mentioned device positions and guides the drill tool during deep hole machining, especially for deep hole machining processes with a large hole depth to hole diameter ratio and long shaft workpieces with axial through holes. While ensuring the positioning accuracy of the drilling position, the positioning and guiding device can suppress the shaking and deflection of the drill tool during machining based on the drill sleeve structure, thereby completing the high-quality drilling, reaming and eccentric hole machining process in cooperation with the machining clamp of the workpiece. However, the length and position of the positioning plate are fixed, and the positioning plate cannot be flexibly adjusted to support the position when machining workpieces with different hole depths. The applicability is low. In addition, it is difficult to dissipate heat during deep hole drilling. The above-mentioned device cannot dissipate heat at the bottom end of the drill bit, affecting the service life of the drill bit. Practical new type content
