DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-Figure 5 As shown, the embodiment of the present invention proposes a rotary power mechanism for a five-axis linkage machining center. This mechanism is a major component of the five-axis linkage machining center, used to drive the tool to rotate at high speed and adjust the tool's machining position. Specifically, it includes a mounting plate 1 and a slide rail 2 spaced apart from the mounting plate 1. The slide rail 2 is mounted on a sliding seat 3 and a clamping structure 4 fixed to the sliding seat 3. The clamping structure 4 is used to mount and clamp a machining driver 5. As the sliding seat 3 moves on the slide rail 2, the position of the machining driver 5 can be adjusted. The clamping structure 4 includes a connecting plate 41 fixed to the sliding seat 3 and a clamping seat 42 provided on the connecting plate 41. The clamping seat 42 is provided with a mounting step hole 43. An opening 44 communicating with the mounting step hole 43 is provided on one side of the clamping seat 42. A fastener is provided on the clamping seat 42 for adjusting the size of the opening 44. A processing driver 5 is inserted into the mounting step hole 43. When replacing different types of processing drivers 5, the opening 44 is adjusted to adapt to the size. At the same time, the opening 44 is locked by the fastener, thereby enabling different types of processing drivers 5 to be clamped and fixed. The processing driver 5 is a mature product commonly used in existing five-axis linkage processing machines, used to clamp and fix the tool and rotate it at high speed. The provision of the opening 44 enables the adaptive installation of different types of processing drivers 5.

[0027] At the same time, a driving assembly 6 for driving the sliding seat 3 to move relative to the slide rail 2 is provided on the mounting plate 1, and the moving position of the sliding seat 3 on the slide rail 2 is adjusted by the driving assembly 6. Specifically, the driving assembly 6 includes a screw rod 61 rotatably mounted on the mounting plate 1, and the screw rod 61 is located between the two slide rails 2. The sliding seat 3 is provided with a nut that is threadedly engaged with the screw rod 61. One end of the screw rod 61 is connected to a reducer and a drive motor 62. The drive motor 62 and the reducer drive the screw rod 61 to rotate and threadably engage with the nut. The sliding seat 3 is restricted by the slide rail 2 to only slide, and the threaded engagement is converted into movement of the sliding seat 3 relative to the slide rail 2, thereby adjusting the position of the clamping structure 4.

[0028] Specifically, in order to ensure the stable rotation of the screw rod 61, a rotating seat 63 is provided on the mounting plate 1 at both ends thereof. The screw rod 61 is mounted on the two rotating seats 63 through bearings, and is positioned and mounted on the mounting plate 1 through the rotating seat 63 to achieve stable installation of the screw rod 61. A positioning reference surface 7 for positioning the rotating seat 63 is provided on the mounting plate 1. The positioning reference surface 7 includes a first positioning surface 71 and a second positioning surface 72 perpendicular to the first positioning surface 71. The rotating seat 63 is positioned in two directions by the first positioning surface 71 and the second positioning surface 72 perpendicular to each other, thereby ensuring the accuracy of the installation axis of the screw rod 61.

[0029] At the same time, in order to ensure the stability of the clamping structure 4, the clamping structure 4 is an integrated structure.

[0030] When the entire clamping structure 4 is installed on the sliding seat 3, the installation position can be adjusted. Specifically, a plurality of installation holes 8 evenly distributed along the length direction are provided on the sliding seat 3, and fastening holes 9 corresponding to the installation holes 8 are provided on the connecting plate 41. The spacing between the plurality of installation holes 8 can realize the change of the locking position of the fastening holes 9.

[0031] Specifically, the slide rail 2 is used to slide and guide the sliding seat 3, and the slide rail 2 includes a rail 21 fixed on the mounting plate 1, and a slider 22 fixed on the sliding seat 3. The slider 22 slides with the rail 21, and the sliding cooperation between the slider 22 and the rail 21 can achieve stable sliding under the load-bearing effect.

[0032] The entire rotary power mechanism is installed on the five-axis linkage processing machine through the mounting plate 1. Specifically, a mounting reference surface 10 is provided on the side of the mounting plate 1 away from the slide rail 2. The mounting reference surface 10 achieves plane matching during installation to ensure installation stability.
