Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a double-station double-spindle numerical control machining center. Background Art

[0002] The dual-station dual-spindle CNC machining center is a CNC machine tool with two working positions and two spindles. It is usually used to efficiently process large and complex parts and has the following characteristics: High processing efficiency: The two spindles can be processed at the same time, thereby improving production efficiency. High precision: The use of CNC technology can achieve high-precision processing.

[0003] At present, the existing CNC machining will produce some processing debris when processing materials. If these debris are not cleaned up in time, they will accumulate more and more on the machine tool, thus affecting the working efficiency of the machine tool. In serious cases, it will definitely cause damage to the machine tool. The CNC machining center with dual stations and dual spindles produces more debris in the same time, so the cleaning frequency is high and the equipment is more expensive. If it is not handled in time and causes damage, it will cause greater economic losses. However, at present, it is generally cleaned by manually taking the dust collection component or manually taking the cleaning tool for cleaning, which is not very convenient and practical. Therefore, the structure of the dual-station dual-spindle CNC machining center is enriched to improve its functionality, so a dual-station dual-spindle CNC machining center is proposed.

DETAILED DESCRIPTION

[0021] 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 of the embodiments.

[0022] Reference Figure 1-5 A double-station dual-spindle CNC machining center includes a machining table 1 and a protective cover 2. The protective cover 2 is arranged above the machining table 1. The machining table 1 is provided with an axis assembly and a positioning tool. The protective cover 2 is also connected to the top of the workshop through a cylinder 3, and can be raised and lowered to cover the axis assembly and the positioning tool and other components, thereby playing a protective role during the machining process. The above components are all conventional components of the prior art. The attached drawings of this scheme are only simple structural schematic diagrams. The specific structure and working principle can be disclosed by referring to the prior art.

[0023] A lifting block 4 is provided in the protective cover 2 through a cylinder 3, and two mounting frames 7 are installed on the lifting block 4. A transmission chamber 14 is provided inside the lifting block 4, and screws 8 extending into the transmission chamber 14 are provided on the two mounting frames 7. A driving motor 15 is provided in the transmission chamber 14, and the screw 8 is connected to the driving motor 15 through a rotating mechanism. A nut 9 is threadedly sleeved on the screw 8, and a connecting frame 11 is provided on the nut 9 through an insertion mechanism. The connecting frame 11 is connected to the mounting frame 7 through a disassembly and assembly mechanism, and a dust collection cylinder 5 is provided on the connecting frame 11 through a dust collection pipe 6.

[0024] The rotating mechanism includes a driving gear 16 installed on the output shaft of the driving motor 15, and a transmission gear 17 is provided at the end of the screw 8. The driving gear 16 is meshed with the transmission gear 17. As shown in the figure, the driving gear 16 and the transmission gear 17 are both bevel gears, and the mutual meshing realizes the power transmission of the driving motor 15, so that the two screws 8 can be rotated synchronously after the driving motor 15 is started. The direction of the threads on the two screws 8 is set according to their rotation direction to ensure that the two nuts 9 move closer or farther synchronously.

[0025] The plug-in mechanism includes an insert block 18 installed on the nut 9, and a slot corresponding to the insert block 18 is provided on the surface where the connecting frame 11 contacts the nut 9. When the insert block 18 is in the slot, when the nut 9 moves on the screw rod 8, the synchronous movement of the connecting frame 11 and other components can be achieved.

[0026] The disassembly mechanism includes a disassembly block 12 mounted on the nut 9. The mounting frame 7 is provided with a disassembly opening 13 corresponding to the disassembly block 12. When the disassembly block 12 is at the horizontal part of the disassembly opening 13, the connection frame 11 can be prevented from being separated from the nut 9.

[0027] A limiting rod 10 is provided in the mounting frame 7 , the limiting rod 10 is parallel to the screw rod 8 , and the limiting rod 10 slides through the nut 9 , so that the limiting rod 10 limits the nut 9 and effectively prevents the nut 9 from rotating together with the screw rod 8 .

[0028] The disassembly and assembly port 13 is designed in an L-shape, and the contact surface between the connecting frame 11 and the nut 9 is designed in an arc shape. The above-mentioned current design is suitable for the connection and disconnection between multiple components. The specific current situation is shown in the attached drawings, which can be completed by relying on the equipment in the existing technology.

[0029] When the utility model is used, after the processing table 1 is completed, the residual waste chips are cleared. At this time, the protective cover 2 is kept in an ascending and detached state. At this time, the cylinder 3 is started to lower the lifting block 4 and other components, and drive the dust collection tube 5 and other components to descend, and the dust collection pump component not shown in the figure is started, so that the dust collection tube 6 and the dust collection tube 5 can be used to suck away the waste chips and clean them.

[0030] In this solution, after starting the driving motor 15, the screw 8 can be driven to rotate. When the screw 8 rotates, the nut 9 installed thereon will drive the connecting frame 11 to move, thereby adjusting the position of the dust collection tube 5 and realizing the waste chip removal operation in multiple areas on the processing table 1.

[0031] In this solution, the driving motor 15 is continuously started to make the connecting frame 11 move continuously and approach the lifting block 4, and finally the disassembly block 12 moves to the vertical part of the disassembly port 13. At this time, the connecting frame 11 will fall vertically and disengage from the nut 9, thereby realizing the convenient disassembly of the dust collection tube 5. A protective net is provided on the dust collection tube 5 to prevent large particles of waste from being sucked in and causing blockage. The mesh of the protective net may be blocked, and it is convenient to clean it or replace the protective net with different apertures in the disassembled state.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
