DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] A dual-spindle turret machine tool, such as Figures 1 to 6 As shown, it includes a base 1, a spindle seat 2 on which a spindle body 3 is rotatably arranged, and a power turret 4. The spindle seat 2 is installed on the base 1, and a clamp 5 for clamping a workpiece is arranged at the end of the spindle body 3. In this embodiment, there are two spindle seats 2 and the two are spaced apart, and the spindle body 3 is driven by a rotating hydraulic cylinder.

[0027] A linear drive module 1 6 and a linear drive module 2 7 are provided on the base 1. The linear drive module 1 6 and the linear drive module 2 7 are both used to drive the power turret 4 so that the tool on the power turret 4 approaches or moves away from the workpiece on the fixture 5. Specifically, the linear drive module 1 6 is connected to a support plate 8, the linear drive module 2 7 is arranged on the support plate 8, the linear drive module 2 7 is connected to a base plate 10, and the power turret 4 is arranged on the base plate 10.

[0028] In the present embodiment, there are two linear drive modules 1 6 and two linear drive modules 2 7 , and the linear drive modules 1 6 , the linear drive modules 2 7 and the spindle seat 2 correspond one to one.

[0029] The linear drive module 6 includes a rotation drive source 61, a screw body 62, a screw nut 63, a slide rail 64 and a slider 65. The rotation drive source 61 is preferably a motor, and other drive sources with a rotation function can also be used. The output end of the rotation drive source 61 is connected to the screw body 62, the screw nut 63 is threadedly matched with the screw body 62, the screw nut 63 is connected to the support plate 8, the slide rail 64 is arranged on the base 1 along the axial direction of the spindle body 3, the slider 65 is slidably arranged on the slide rail 64, and the slider 65 is connected to the support plate 8. The screw body 62 is driven to rotate by the rotation drive source 61, the screw nut 63 moves along the length direction of the screw body 62, the support plate 8 moves with the screw nut 63, and the linear drive module 27, the base plate 10 and the power turret 4 move with the support plate 8.

[0030] The linear drive module 2 7 includes a rotation drive source 2 71, a synchronous wheel 1 72, a synchronous wheel 2 73, a transmission belt 74, a screw body 2 75, a screw nut 2 76, a slide rail 2 77 and a slider 2 78. The rotation drive source 2 71 is preferably a motor, and other drive sources with a rotation function can also be used. The output end of the rotation drive source 2 71 is connected to the synchronous wheel 1 72, the synchronous wheel 2 73 is connected to the screw body 2 75, the synchronous wheel 1 72 and the synchronous wheel 2 73 are connected through the transmission belt 74, and the screw nut 2 76 is connected to the screw body 2 75. The threaded joints 76 are connected to the base plate 10, the slide rail 77 is arranged on the support plate 8, the slider 78 is slidably arranged on the slide rail 77, and the slider 78 is connected to the base plate 10, and the synchronous wheel 1 72 is driven to rotate by the rotating driving source 2 71, and the synchronous wheel 1 72 drives the synchronous wheel 2 73 to rotate through the transmission belt 74, and the synchronous wheel 2 73 drives the screw body 2 75 to rotate, and the screw nut 2 76 moves along the length direction of the screw body 2 75, the base plate 10 moves with the screw nut 2 76, and the power turret 4 moves with the base plate 10.

[0031] It should be noted that the rotation drive source 2 71 is installed on the support plate 8, and the rotation drive source 2 71 is located directly below the support plate 8. The rotation drive source 2 71 drives the screw body 2 75 to rotate through the cooperation of the synchronous wheel 1 72, the synchronous wheel 2 73 and the transmission belt 74. This layout is more compact and can effectively reduce space occupancy.

[0032] The linear drive module 6 is located on one side of the spindle seat 2. The linear drive module 6 is driven along the axial direction of the spindle body 3. The driving direction of the linear drive module 6 is relatively perpendicular to the driving direction of the linear drive module 2 7. It should be noted that this spatial layout of the spindle seat 2 and the linear drive module 6 makes the structure more compact and the space utilization rate is higher, which can effectively reduce the space occupancy and shorten the stroke of the linear drive module 6 driving the power turret 4, so that the tool on the power turret 4 can approach or move away from the workpiece on the fixture 5 faster, reducing the time required for the tool to move during the processing, which can effectively improve the processing efficiency.

[0033] It should be noted that, as the longer the screw rod travels, its stability is often affected and it is more susceptible to external vibrations. Therefore, by shortening the travel of the driving power turret 4 during processing, the stability during processing can be effectively improved and the processing accuracy can be ensured.

[0034] Preferably, the spindle seat 2 corresponds to the middle part of the screw body 62 along the driving direction of the linear drive module 2 7, and the power turret 4 moves along the length direction of the screw body 62, so that when the tool on the power turret 4 approaches or moves away from the workpiece on the fixture 5, the stroke of the power turret 4 during processing is shortened, which can reduce the unstable factors of long-term and long-distance movement on the screw body 62. The shorter stroke makes the power turret 4 less affected by external vibration during the processing, thereby improving the stability of the power turret 4 during the processing, which is more conducive to maintaining the processing accuracy.

[0035] A truss 9 is installed on the spindle seat 2, and the truss 9 includes a support frame 91, a mechanical arm 92, a drive assembly 1 93 and a drive assembly 2 94.

The drive assembly 2 94 is used to drive the mechanical arm 92 to move in the vertical direction. A slide 12 is slidably arranged on the support frame 91, and the mechanical arm 92 is slidably arranged on the slide 12. The drive assembly 1 93 includes a rotation drive source 3 931, a gear 1 932 and a rack 1 933. The rotation drive The power source three 931 is installed on the slide 12, the output end of the rotational drive source three 931 is connected to the gear one 932, the rack one 933 is arranged along the driving direction of the linear drive module two 7, and the gear one 932 is meshed with the rack one 933; the driving component two 94 includes a rotational drive source four 941, a gear two 942 and a rack two 943, the rotational drive source four 941 is installed on the slide 12, the output end of the rotational drive source four 941 is connected to the gear two 942, the rack two 943 is arranged on the robot arm along the vertical direction, and the gear two 942 is meshed with the rack two 943.

[0036] The gear one 932 is driven to rotate by the rotating driving source three 931, and the gear one 932 cooperates with the rack one 933 to drive the slide 12, the driving component two 94 and the boom to move. The gear two 942 is driven to rotate by the rotating driving source four 941, and the gear one 932 cooperates with the rack one 933 to drive the boom to move.

[0037] In this embodiment, through the cooperation of drive component 1 93 and drive component 2 94, the robot arm 92 is driven to move close to the fixture 5, so as to take the workpiece away from the fixture 5 or transport the workpiece to be processed to the fixture 5. The degree of automation is high and the production efficiency can be effectively improved.

[0038] It should be noted that, by installing the truss 9 on the two spindle seats 2, this layout makes the structure more compact and can effectively reduce space occupation.

[0039] A guide slope 11 is provided on the base 1, and the guide slope 11 is located directly below the ends of the two spindle bodies 3. The guide slope 11 is set from high to low from the end close to the spindle body 3 to the end far away from the spindle body 3, so that the debris generated during processing falls onto the guide slope 11, and is concentrated to the corresponding position through the guiding effect of the guide slope 11 and its own gravity, thereby realizing the centralized collection of the debris.

[0040] A chip storage groove 13 is provided on the upper surface of the base, and the lowest part of the guide slope 11 extends to the chip storage groove 13 , so that the debris is collected in the chip storage groove 13 .
