Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The driving system of the CNC machining center includes a vertical arm device 7 and a spindle device 8 .

[0024] Such as Figure 1 to Figure 4 As shown, the vertical arm device 7 includes a cross arm 71 , a fourth shaft sliding seat 72 , a fourth shaft driving mechanism 73 , a fifth shaft sliding seat 74 and a fifth shaft driving mechanism 75 .

[0025] The cross arm 71 includes a cross arm bottom plate 711 and a cross arm flange 712 bent upward from the peripheral edge of the cross arm bottom plate 711 , so that the strength of the cross arm 71 can be improved. A fourth servo motor fixing plate 713 protrudes outward from one side of the cross arm bottom plate 711 . A fourth guide rail 714 is fixed on the cross arm bottom plate 711 , and a fourth slide block 715 is provided sliding on the fourth guide rail 714 .

Abstract

The invention discloses a driving system of a numerical control machining center. The driving system comprises a vertical arm device and a spindle device, wherein the vertical arm device comprises a cross arm, a fourth shaft sliding seat, a fourth shaft driving mechanism, a fifth shaft sliding seat and a fifth shaft driving mechanism; the fourth shaft sliding seat comprises a fourth shaft bottom plate, fourth shaft side plates, a fourth shaft front plate and a fourth shaft top plate; a fourth notch is formed in one side of the fourth shaft bottom plate, a guide block is fixed at the fourth notch, and a guide groove is formed in the guide block; a guide piece is fixed at the bottom of the cross arm; vertical guide grooves are formed in the two fourth shaft side plates; the fifth shaft sliding seat penetrates through the vertical guide grooves; the spindle device comprises a spindle fixing seat, a spindle and a spindle driving mechanism; the spindle driving mechanism comprises a driving motor, a driving belt pulley, a driven belt pulley and a belt; the driving motor is sleeved with a retaining ring, and a cooling fin is arranged on the retaining ring. With the adoption of the driving system, the fourth shaft sliding seat can be guided initially, and the motion precision of the fifth shaft sliding seat is high, so that the driving motor can be better cooled.

Description

technical field [0001] The invention relates to a numerical control machining center. Background technique [0002] The existing CNC machining center includes a base, a column, a workbench assembly and a spindle. The column is fixed on the base, the workbench assembly is arranged on the base, and the main shaft slides on the column. The spindle can only move in the vertical direction, and the movement is not highly guided. The main shaft is driven by a drive motor, which generates a large amount of heat when it is working, and if the heat is not dissipated in time, the drive motor will be burnt out. Contents of the invention [0003] In order to initially guide the sliding seat of the fourth axis, to make the movement precision of the fifth sliding seat high, and to better dissipate heat from the driving motor, the present invention provides a driving system for a CNC machining center. [0004] In order to achieve the above object, a driving system of a CNC machining ce...
