All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] Please refer to the attached document. Figures 1-4This application provides a spindle box assembly 100, which is applied to a horizontal machining center and is used to drive the spindle 32 to move.

[0024] Please refer to the attached document. Figures 1-4 In this embodiment, the spindle box assembly 100 includes a bracket 10, a spindle box 20, and a swivel head assembly 30. The bracket 10 is provided with a first support 11 and a second support 12. The first support 11 and the second support 12 are arranged opposite to each other along the vertical direction of the bracket 10. The first support 11 and the second support 12 form a middle frame space 10a. The spindle box 20 is located within the middle frame space 10a and is supported by the first support 11 and the second support 12. The spindle box 20 is connected to the first support 11 via a first guide rail 40, and the spindle box 20 is connected to the second support 12 via a second guide rail 50. The first guide rail 40 and the second guide rail 50 are disposed on the upper side of the spindle box 20. The spindle box 20 is movably connected to the bracket 10 and moves linearly within the middle frame space 10a. The oscillating head assembly 30 includes an oscillating head body 31 and a spindle 32. The oscillating head body 31 is located on the front side of the spindle box 20 and is rotatably connected to the spindle box 20. The spindle 32 is oscillatingly connected to the oscillating head body 31 and oscillates in the up-down direction. By adding a second support seat 12, the moment of inertia of the spindle box 20 is changed, so that the first support seat 11 and the second support seat 12 can cooperate to limit the range of motion of the spindle box 20 at different positions, reduce the wear on one side of the first guide rail 40, and improve the movement stability of the spindle box 20 of the spindle box assembly 100. At the same time, adjusting the width of the first guide rail 40 and the second guide rail 50 to adapt to spindle boxes 20 of different sizes reduces the displacement and deflection of the spindle 32, which is beneficial for the spindle 32 to stably output cutting force and maintain higher precision.

[0026] The spindle box 20 is located within the middle frame space 10a and is supported by the first support base 11 and the second support base 12. The spindle box 20 is connected to the first support base 11 via the first guide rail 40 and to the second support base 12 via the second guide rail 50.

Simultaneously, the spindle box 20 is movably connected to the bracket 10 and can move linearly within the middle frame space 10a to adjust the front-to-back position of the spindle box 20 relative to the bracket 10. By adding the second support base 12, the moment of inertia of the spindle box 20 is changed, allowing the first support base 11 and the second support base 12 to cooperate in limiting the range of motion of the spindle box 20 at different positions, reducing wear on one side of the first guide rail 40, and improving the movement stability of the spindle box 20 in the spindle box assembly 100. Furthermore, the widths of the first guide rail 40 and the second guide rail 50 can be adjusted to accommodate spindle boxes 20 of different sizes.
