Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a boring head device that can continuously provide power while rotating. Background Technology

[0002] Boring machines are the main equipment for machining large box-shaped parts. They can bore pre-drilled holes in workpieces, and the boring head is the core component of the boring machine. Currently, when the existing boring head rotates for machining, the tool holder is fixed, which means it cannot continuously machine complex shapes and can only machine single shapes. This brings great difficulties to the machining process, requiring manual adjustment of dimensions and trial machining before mass production. It also places high demands on the operator's skills, easily leads to scrap, has a high scrap rate, and slows down the machining efficiency. Utility Model Content

[0003] This invention provides a boring head device that can continuously provide power while rotating, in order to solve the problem in the prior art where the tool holder is fixed when the boring head rotates for machining, and complex shapes cannot be continuously machined.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A boring head device that provides continuous power while rotating includes a motor, a reducer, a spindle, a boring head body, and a slip ring. The motor is fixed to the reducer, which is fixed to the tail of the spindle in the spindle box via a flange. The front end of the spindle is connected to the boring head body. The output shaft of the reducer is connected to a connecting shaft via a key. The connecting shaft is built into the spindle and is connected to a gear via a key. The gear drives a rack to move laterally under the support of a bearing. A tool post is mounted above the rack. The slip ring is connected to the motor inside and to the control system outside.

[0006] The aforementioned slip ring is mounted on a slip ring mounting bracket.

[0007] A pulley is installed at the tail of the aforementioned spindle.

[0008] This invention employs an electric slip ring to provide power and signals to the servo motor. When the spindle rotates, the inner part of the slip ring rotates while the outer part remains stationary. The inner part is connected to the motor, and the outer part is connected to the control system, ensuring the stability of power and signals. The motor is fixed to a reducer, which is secured to the tail of the spindle via a reducer flange. The reducer shaft is connected to a connecting shaft via a key, and the connecting shaft is connected to a gear via a key. When the motor rotates, the gear, supported by bearings, drives the rack to move laterally, converting rotation into motion. A tool holder is mounted above the rack, and it moves accordingly to control the machining range.

[0009] This invention modifies the internal transmission structure of the boring head, enabling it to continuously provide power to the tool holder while the boring head rotates, thus processing complex shapes with high efficiency, high precision, and simple operation. Attached Figure Description

Detailed Implementation

[0014] like Figure 1 and Figure 2 As shown, a boring head device that continuously provides power while rotating includes a motor 1, a reducer 2, a spindle 3, a boring head body 4, and a slip ring 10. The motor 1 is fixed to the reducer 2, which is fixed to the tail of the spindle 3 within the spindle housing 12 via a flange 14. The front end of the spindle 3 is connected to the boring head body 4. The output shaft of the reducer 2 is connected to a connecting shaft 5 via a key. The connecting shaft 5 is housed within the spindle 3 and is connected to a gear 6 via a key. The gear 6, supported by a bearing 7, drives a rack 8 to move laterally. A tool post 9 is mounted above the rack 8. The slip ring 10 is internally connected to the motor 1 and externally connected to the control system. The slip ring 10 is mounted on a slip ring mounting bracket 11. A pulley 13 is mounted at the tail of the spindle 3.

[0015] This invention employs an electric slip ring to provide power and signals to the servo motor. When the spindle rotates, the inner part of the slip ring rotates while the outer part remains stationary. The inner part is connected to the motor, and the outer part is connected to the control system, ensuring the stability of power and signals. The motor is fixed to a reducer, which is secured to the tail of the spindle via a reducer flange. The reducer shaft is connected to a connecting shaft via a key, and the connecting shaft is connected to a gear via a key. When the motor rotates, the gear, supported by bearings, drives the rack to move laterally, converting rotation into motion. A tool holder is mounted above the rack, and it moves accordingly to control the machining range.
