Description

Technical Field

[0001] The present application relates to the technical field of numerical control machining devices, and in particular to a high-efficiency multi-surface machining compound machine tool. Background Art

[0002] Special-purpose machine tools generally have only a single function. When a workpiece needs to be processed using a combination of different types of processing methods, it is often necessary to transfer the workpiece to another type of machine tool for handling and positioning after the processing is completed on one machine tool, which is very time-consuming and has low processing efficiency.

[0003] The use of machining centers can avoid the repeated movement of workpieces, because machining centers generally have three-axis gantry modules. By replacing different tools at the power output end of the three-axis gantry module, the workpiece can be processed in a combination of processing methods. However, machining centers need to frequently replace tools to achieve different types of tool processing. During the process of replacing tools, the workpiece is in a standby state, resulting in insufficient use of processing time. Utility Model Content

DETAILED DESCRIPTION

[0025] Please refer to Figure 1 - Figure 3 This embodiment provides a high-efficiency multi-surface machining compound machine tool, comprising:

[0026] Rack 1;

[0027] A spindle assembly 2, wherein the spindle assembly 2 is mounted on the frame 1;

[0028] A first processing device 3, which is arranged beside a first processing area 4 at a power output end of the spindle assembly 2;

[0029] A rotary positioning feeding assembly, the rotary positioning feeding assembly comprising a rotary platform 5 and a plurality of clamping mechanisms 6 arranged on the rotary platform 5; the rotary platform 5 and the clamping mechanisms 6 in the rotary positioning feeding assembly are located on the opposite side of the power output end of the spindle assembly 2;

[0030] The second processing device 7 is arranged beside the second processing area 8 of the rotating platform 5 .

[0031] The frame 1 plays a supporting role.

[0032] Embodiment 1

[0033] The power output end of the spindle assembly 2 is consistent with the power output end of the spindle assembly 2 of a conventional lathe, and has a three-jaw chuck or a clamp with the same function as a three-jaw chuck to clamp the workpiece to be processed, and the processing tool 320 in the first processing device 3 can be a turning tool. The spindle assembly 2 drives the workpiece to be processed to rotate, and the processing tool 320 in the first processing device 3 which is a turning tool performs turning processing on the workpiece located in the first processing area 4.

[0034] Among the multiple clamping mechanisms 6 located on the rotating platform 5 of the rotating positioning feeding assembly, at least one clamping mechanism 6 is empty and does not clamp a workpiece, corresponding to the workpiece clamped by the power output end of the spindle assembly 2. The other clamping mechanisms 6 on the rotating platform 5 can clamp the workpiece to be processed, or the workpiece that has been processed by the processing tool 320 in the first processing device 3, and these workpieces can be transported by the rotating platform 5. The processing tool 720 of the second processing device 7 located next to the second processing area 8 can process different workpieces at the same time with the first processing device 3, and the workpiece can be processed at different azimuth angles. The rotating platform 5 plays the role of transporting the workpiece to be processed and clamping and positioning the workpiece.

[0035] After the workpiece clamped on the power output end of the spindle assembly 2 is processed in the first processing area 4, it is transferred to the clamping mechanism 6 on the rotating platform 5 for clamping and transportation.

[0036] Embodiment 2

[0037] The power output end of the spindle assembly 2 can be equipped with any of a drill, a milling cutter, and a turning tool. The clamping mechanism 6 plays the role of clamping and conveying the workpiece. The machining tool 320 of the first machining device 3 and the tool set at the power output end of the spindle assembly 2 both process the workpiece in the first machining area 4, but the two do not process at the same time, and the end faces of the workpiece can be processed at different azimuth angles. The workpiece clamped in the clamping mechanism 6 corresponding to the second machining area 8 on the rotating platform 5 can be synchronously processed by the machining tool 720 of the second machining device 7.

[0038] In this embodiment, the workpiece is clamped into the clamping mechanism 6 from the loading process, and is subsequently only rotated and transported to different processing areas or areas between processing areas by the rotating platform 5. The workpiece does not need to be removed and re-clamped for positioning in different processing areas. If one of the first processing device 3 and the second processing device 7 needs to change the tool, the other one will not be affected and can continue processing without waiting. Therefore, the processing efficiency is greatly improved and the processing time is fully utilized. This high-efficiency multi-faceted composite machine tool, especially for multi-faceted composite processing of short-axis workpieces, plays a prominent role in improving production efficiency.

[0039] In some embodiments, the clamping mechanism 6 can be an electric finger or a finger cylinder to clamp the workpiece. The workpiece can be rotated from the rotating platform 5 to the clamping mechanism 6 of the loading and unloading station for loading or unloading by using automated equipment while the machine tool is running without stopping.

[0040] In some embodiments, the clamping mechanism 6 can be installed on the rotating platform 5 through a rotating device (not shown), and the rotating device can drive the clamping mechanism 6 and the workpiece clamped by the clamping mechanism 6 to rotate and adjust the orientation, which can further enrich the multi-faceted processing of the workpiece. The rotating device can be a device that can realize rotational drive, such as a motor, a rotating cylinder, a steering gear, etc.

[0041] Please refer to Figure 1 - Figure 3 The first processing device 3 includes a tool changing tool holder 310 , and the tool changing tool holder 310 is arranged on the opposite side of the processing tool 320 of the first processing device 3 .

[0042] The first processing device 3 includes a first transfer module 330 , and the first transfer module 330 is used to drive the processing tool 320 in the first processing device 3 to move between the first processing area 4 and the opposite side area of ​​the first processing device 3 .

[0043] The area on the opposite side of the first processing device 3, that is, the area after the spindle assembly 2, is where the tool changer 310 is located. The tool changer 310 and the processing tool 320 are located on both sides of the spindle assembly 2, respectively. The tool changer 310 is arranged on the opposite side of the processing tool 320 of the first processing device 3, so that the first transfer module 330 drives the processing tool 320 to move in the first processing area 4 to process the workpiece.

[0044] The first transplanting module 330 can drive the processing tool 320 to move to the position of the tool changing tool holder 310 for automatic tool changing. The tool changing tool holder 310 can preset multiple tools corresponding to the tools used in the processing process in advance. The tool changing tool holder 310 can be implemented with existing technology, which is not the focus of the innovation of the utility model of this application, and will not be repeated here.

[0045] Please refer to Figure 1 - Figure 3 The second processing device 7 includes a second transplanting module 710, and the second transplanting module 710 is used to drive the processing tool 720 in the second processing device 7 to move in the area of ​​the second processing area 8 or move away from the rotating platform 5.

[0046] When the second transplanting module 710 drives the processing tool 720 in the second processing device 7 to move in the area of ​​the second processing area 8, the second transplanting module 710 can carry the tool to process the designated position of the workpiece.

[0047] When the second transplanting module 710 drives the processing tool 720 in the second processing device 7 to move away from the rotating platform 5, space can be freed up to facilitate the processing tool 720 to replace the required tool.

[0048] Please refer to Figure 1 - Figure 3 The rotary positioning feeding assembly includes a third transplanting module 9, and the third transplanting module 9 is used to drive the rotating platform 5 to move closer to or away from the power output end of the main shaft assembly 2.

[0049] The spindle assembly 2 itself has a Y-direction linear module 210, which can drive the spindle assembly 2 to move along the Y-axis direction. The moving direction of the third transplanting module 9 is the same as the spindle length direction in the spindle assembly 2, which is also the Y-axis direction.

[0050] Please refer to Figure 1 - Figure 3 There are four clamping mechanisms 6 , which are evenly distributed on the rotating platform 5 .

[0051] It includes a third processing device 10, which is arranged on the opposite side of the power output end of the spindle assembly 2, and the rotating platform 5 and the clamping mechanism 6 in the rotating positioning feeding assembly are located between the power output end of the spindle assembly 2 and the third processing device 10.

[0052] The four clamping mechanisms 6 evenly distributed on the rotating platform 5 can clamp the workpiece being processed at the same time. Then, the first processing device 3 and the third processing device 10 correspond to the workpieces clamped by the two clamping mechanisms 6 in the positive and negative directions of the Y axis of the processing space coordinate axis, respectively, and the second processing device 7 corresponds to the workpiece clamped by the lower clamping mechanism 6 in the Z axis direction.

[0055] In a preferred embodiment, the number of the third transplanting module 9 in the rotating positioning feeding assembly is one, which is a linear module of a lead screw nut seat driven by a motor, and the number of the driving motor 520 is also one installed at the power output end of the third transplanting module 9, which is equivalent to two groups of symmetrically arranged spindle assemblies 2, first processing devices 3, rotating positioning feeding assemblies, second processing devices 7, and third processing devices 10, sharing the frame 1, and the power of the third transplanting module 9 and the driving motor 520, so the rotation of the two groups of rotating support plates 510 is also synchronous, which can realize two groups of synchronous processing, reasonably make full use of resources, and reduce manufacturing costs. This design is ingenious and reasonable. With the third transplanting module 9, a linear module, as the boundary, the two groups are symmetrically distributed with the axis of the lead screw length direction in the third transplanting module 9 as the symmetry center line.

[0056] Of course, the number of the third transplanting modules 9 and the driving motors 520 can also be two groups, respectively providing services for two groups of machine tools.

[0057] Preferably, the projection profile of the rotating support plate 510 is circular.

[0058] The third transplanting module 9 is a linear module of a lead screw nut seat type driven by a motor, and its nut seat is connected to a matching guide rail seat 12 to provide high-precision guidance for the movement of the driving motor 520, the rotating support plate 510, and the clamping mechanism 6.

[0061] Preferably, the X-axis linear module 331 and the Z-axis linear module 332 are connected with a guide rail and guide seat pair 13 to provide guidance for the movement of the machining tool 320 .
