[0023] Reference Figure 1-3 As shown, it is a preferred embodiment provided by the utility model.

[0024] A dual-drive processing machine tool comprises a base 2, a beam 3 and two dual-drive modules 1. The base 2 and the beam 3 are movably assembled. The two dual-drive modules 1 are respectively installed on both sides of the beam 3. The two dual-drive modules 1 are used to synchronously drive the beam 3 to be movable relative to the base 2. The base 2 comprises a rack 4, which is extended along the X direction. The dual-drive module 1 comprises a first servo motor 11, a second servo motor 12, a first gear 13 and a second gear 16. The first servo motor 11 is used to drive the first gear 13, the second servo motor 12 is used to drive the second gear 16, and the first gear 13 and the second gear 16 are used to be meshed with the rack 4.

[0025] When the above-mentioned dual-drive processing machine tool is driven, the two dual-drive modules 1 apply driving force synchronously to ensure sufficient driving force application. At the same time, the force on both sides of the beam 3 is evenly applied, which facilitates the movable arrangement of the beam 3 relative to the base 2; under the action of the first servo motor 11 and the second servo motor 12, the driving force is synchronously applied to the first gear 13 and the second gear 16. Once the rotation speeds of the first gear 13 and the second gear 16 are inconsistent, the first servo motor 11 and the second servo motor 12 play a role in speed correction with each other, thereby making the movement of the beam 3 more stable.

[0026] The control panel is preset with a correction program. When the feedback rotation speeds of the first gear 13 and the second gear 16 are inconsistent, a judgment is made to determine whether it is overspeeding or underspeed. If it is overspeeding, the overspeeding servo motor is controlled to slow down until the rotation speeds of the first servo motor 11 and the second servo motor 12 are consistent. If it is underspeed, the low-speed servo motor is controlled to accelerate until the rotation speeds of the first servo motor 11 and the second servo motor 12 are consistent, thereby realizing mutual correction between the first servo motor 11 and the second servo motor 12.

[0027] The dual-drive module 1 includes a first gear seat 15 and a second gear seat. The first gear seat 15 is assembled with the first servo motor 11, and the first gear 13 is installed on the first gear seat 15.

From top to bottom, the second servo motor 12, the second gear seat and the second gear 16 are arranged in sequence.

[0028] Under the action of the first tooth seat 15, the first gear 13 is easily set and helps to enhance the stability of the setting of the first gear 13.

[0029] The dual-drive module 1 includes a drive frame 14, which is fixedly arranged with the crossbeam 3; the first gear seat 15 and the second gear seat are respectively mounted on the drive frame 14, and under the action of the drive frame 14, the stability of the first gear seat 15 and the second gear seat is enhanced, thereby ensuring the stability of the first gear 13 and the second gear 16.

[0030] And along the X direction, the first tooth seat 15 and the second tooth seat are arranged flush with each other; the installation levels of the first gear 13 and the second gear 16 are consistent. As long as the specifications of the first gear 13 and the second gear 16 are consistent, it can be ensured that the first gear 13 and the second gear 16 are arranged flush, which facilitates the first gear 13 and the second gear 16 to be synchronously meshed with the rack 4.

[0031] The crossbeam 3 includes two beam-column seats, and the two dual-drive modules 1 are respectively installed on the two beam-column seats; under the action of the two beam-column seats, the dual-drive module 1 is conveniently arranged, and under the action of the beam-column seats, the crossbeam 3 and the base 2 are conveniently matched.

[0032] A column groove is formed in the middle of the beam-column seat, and the first servo motor 11 is placed in the column groove, and the first servo motor 11 is arranged longitudinally. Along the X direction, the beam-column seat and the second servo motor 12 are assembled in abutment with each other. In this way, under the action of the column groove, it helps to reduce the dead weight of the beam-column seat, facilitates the movement of the beam-column seat, and at the same time, protects the first servo motor 11 and improves the setting stability of the first servo motor 11. At the same time, it supports and reinforces the second servo motor 12 and improves the setting stability of the second servo motor 12.

[0033] The beam-column seat includes two support columns, a column groove is formed between the two support columns, the first servo motor 11 is fixedly arranged with one support column, and the second servo motor 12 is fixedly arranged with the other support column; thus, under the action of the support columns, the stability of the setting of the first servo motor 11 and the second servo motor 12 is improved.

[0034] The dual-drive machining center comprises a control panel. Two dual-drive modules 1 are electrically connected to the control panel respectively. The control panel synchronously outputs instructions to control the first servo motor 11 and the second servo motor 12 .

[0036] The two dual-drive modules 1 are aligned along both sides of the crossbeam 3 , and the first servo motors 11 of the two dual-drive modules 1 are aligned, and the second servo motors 12 of the two dual-drive modules 1 are aligned, thereby improving the movement stability of the crossbeam 3 .

[0038] In this way, the coordination effect between the rack 4 and the first gear 13 and the second gear 16 is better, the noise is smaller, and the movement is smoother.

[0039] The inclination angles of the first wheel and the second wheel are arranged in a consistent manner, ensuring consistent output of driving force.

[0040] The base 2 includes two seat surfaces, which are arranged on both sides corresponding to each other, and are arranged in an upward flared shape. The seat surfaces are extended along the X direction, and the rack 4 is laid flat on the seat surfaces, and the rack 4 is arranged along the vertical horizontal plane; in this way, it is convenient for the rack 4 to engage with the first gear 13 and the second gear 16, thereby facilitating the transmission of driving force.
