Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and manufacturing, and in particular to a dual four-axis rotary table with a linkage mechanism. Background Technology

[0002] In recent years, with the rapid development of my country's high-end manufacturing industry and national economy, there has been an increasing number of large, complex, and high-precision parts in mechanical equipment. Traditional three-axis CNC machine tools suffer from problems such as low processing efficiency, the need for multiple clamping operations, and the inability to guarantee accuracy, making it difficult to meet the requirements of high-end CNC manufacturing. Therefore, four-axis rotary tables have emerged.

[0003] A four-axis rotary table typically includes three linear axes (X, Y, Z) and one rotary axis (A or C). It can perform movement along the three linear axes and rotation along the rotary axis, and is often used for planar machining and simple three-dimensional machining.

[0004] In the existing technology, the output head of a four-axis rotary table processes a single part at a time, which cannot meet the requirements of synchronous linkage processing with other rotary tables, and its processing efficiency is also limited.

[0005] In view of this, this technical solution proposes a dual four-axis rotary table with a linkage mechanism, which connects two (or more) four-axis rotary tables through the linkage mechanism, enabling them to perform synchronous / asynchronous processing actions. While improving processing efficiency, it also meets the requirement that some parts need to be processed simultaneously. The overall structure is simple and easy to assemble, disassemble and replace. Utility Model Content

[0006] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a dual four-axis rotary table with a linkage mechanism, thereby addressing the problems of insufficient linkage machining structure and low machining efficiency in existing four-axis rotary tables.

[0007] To achieve the above objectives, this utility model provides a dual four-axis turntable with a linkage mechanism, comprising a first four-axis turntable body, a second four-axis turntable body, and a linkage mechanism.

[0008] The first four-axis turntable body and the second four-axis turntable body are placed parallel and aligned.

[0009] The linkage mechanism includes a synchronizing rod and a connecting rod connected to the synchronizing rod. The connecting rod is connected to a telescopic device.

[0010] Opposite to the output ends of the first and second four-axis rotary table bodies, there are respectively a first loading head and a second loading head for cooperating in processing products.

[0011] The first four-axis turntable body and the second four-axis turntable body can cooperate with the first loading head and the second loading head for processing simultaneously through the synchronous extension and retraction of the linkage mechanism.

[0012] As a further embodiment of this utility model, the telescopic device is located in the middle of the first four-axis turntable body and the second four-axis turntable body, and its bottom is fixed by a mounting base.

[0013] As a further embodiment of this utility model, the bottom of the mounting base is fixed to a machine platform, and the main body of the first four-axis turntable and the main body of the second four-axis turntable are both disposed on the machine platform.

[0014] As a further embodiment of this utility model, the synchronizing rod is provided with a detachable connecting plate, and the synchronizing rod is connected to the connecting rod through the connecting plate.

[0015] As a further improvement of this utility model, the telescopic device is a telescopic cylinder.

[0016] As a further improvement of this utility model, both the first feeding head and the second feeding head are retractable feeding head structures.

[0017] As a further embodiment of this utility model, the product is an impeller.

[0018] As a further embodiment of this utility model, an air blowing mechanism for blowing down the product is provided between the first four-axis turntable body and the second four-axis turntable body.

[0019] As a further embodiment of this utility model, the air blowing mechanism includes a mounting bracket fixed to the machine base and air blowing pipes respectively disposed on both sides of the mounting assembly, with the head of the air blowing pipe facing the product processing position.

[0020] The beneficial effects of this utility model are as follows:

[0021] This technical solution connects the parallel-aligned first and second four-axis rotary table bodies through a linkage mechanism. A telescopic cylinder is centrally mounted and rigidly fixed to the machine tool via a mounting base, ensuring balanced transmission of driving force and overall stability of the dual rotary tables. The synchronizing rod is connected to the connecting rod via a detachable connecting plate, simplifying assembly and maintenance, reducing stress concentration risks, and ensuring synchronization accuracy. The output ends of the two rotary tables are equipped with corresponding telescopic first and second loading heads to accommodate workpieces of different sizes (such as impellers), reducing adjustment time. The added air-blowing mechanism, via a mounting bracket and air-blowing pipe, automatically blows off the finished product after processing, avoiding manual intervention. The overall structure is compact and efficient, suitable for high-precision, high-volume production scenarios, effectively solving the problems of low efficiency, poor compatibility, and high reliance on manual labor in existing technologies.

[0034] as follows:

[0035] Please see the appendix Figure 1-9

[0036] The main structure includes a first four-axis rotary table body (21), a second four-axis rotary table body (22), and a linkage mechanism (1). The first four-axis rotary table body (21) and the second four-axis rotary table body (22) are placed parallel and aligned. The linkage mechanism (1) includes a synchronizing rod (14) and a connecting rod (11) connected to the synchronizing rod (14). The connecting rod (11) is connected to a telescopic device (10). The output ends of the first four-axis rotary table body (21) and the second four-axis rotary table body (22) are respectively provided with a first feeding head (31) and a second feeding head (32) for cooperating with the processing of products (5). The first four-axis rotary table body (21) and the second four-axis rotary table body (22) can cooperate with the first feeding head (31) and the second feeding head (32) for processing through the synchronous extension and retraction of the linkage mechanism (1).

[0037] The working principle is as follows:

[0038] Traditional four-axis rotary tables suffer from low efficiency and insufficient precision when machining complex parts, mainly because...

[0039] Its structure is simple and lacks coordination, allowing only a single workpiece to be processed at a time. Frequent changes or adjustments to the clamping position are necessary, which is not only time-consuming but also prone to introducing errors due to multiple positioning attempts. In addition, the existing equipment lacks a linkage design, making it difficult to achieve synchronous operation of multiple workstations and limiting overall production capacity.

[0040] This technical solution proposes a dual four-axis rotary table through structural optimization. The core improvement lies in the linkage mechanism (1), which connects the parallel aligned first four-axis rotary table body (21) and the second four-axis rotary table body (22) through a synchronizing rod (14), a connecting rod (11), and a telescopic device (10) to form synchronous action. In the linkage mechanism (1), the synchronizing rod (14) is fixed to the connecting rod (11) through a detachable connecting plate (13). The end of the connecting rod (11) is connected to a telescopic cylinder (10), and the whole assembly is installed on the mounting base (12) in the middle of the two rotary table bodies and rigidly fixed to the machine base (4) to ensure motion stability. The output ends of the two rotary table bodies correspond to the first loading head (31) and the second loading head (32) respectively. Through the synchronous telescopic drive of the linkage mechanism (1), two workpieces can be processed simultaneously, such as high-precision parts like impellers, significantly shortening the single-piece processing cycle.

[0041] The first loading head (31) and the second loading head (32) adopt a telescopic design, which can flexibly adapt to workpieces of different sizes, reducing adjustment time. An air blowing mechanism (6) is added between the two turntables, including a mounting bracket (60) fixed to the machine base (4) and air blowing pipes (61) on both sides. After processing, the finished product is automatically blown off by high-pressure airflow, avoiding manual intervention and further improving efficiency. The machine base (4) has a compact layout, and the rigid connection between the mounting base (12) and the linkage mechanism (1) enhances the overall stability of the equipment, making it especially suitable for high-precision mass production, effectively reducing labor costs and scrap rate.

[0042] The assembly and disassembly process can be,

[0043] During assembly, the machine base (4) is horizontally fixed in the work area. A fixed seat (12) is installed in the center of the machine base (4) to ensure a rigid connection between it and the machine base (4). The first four-axis rotary table body (21) and the second four-axis rotary table body (22) are aligned parallel to each other and fixed on both sides of the machine base (4) respectively. They are then tightened with bolts. The synchronizing rod (14) is fixed to the connecting rod (11) through the detachable connecting plate (13). The end of the connecting rod (11) is connected to the telescopic cylinder (10). Then, the linkage mechanism (1) is installed as a whole on the mounting seat (12) between the two rotary table bodies. The synchronizing rod (14) is adjusted to be aligned with the axis of the output end of the two rotary tables. The first loading head (31) and the second loading head (32) are installed opposite the output ends of the first four-axis rotary table body (21) and the second four-axis rotary table body (22) respectively. Their telescopic stroke is adjusted to adapt to the size of the workpiece to be processed (such as an impeller). A bracket (60) is installed on the machine base (4).

[0044] The air pipe (61) is symmetrically fixed on both sides of the bracket (60). Adjust the position of the head of the air pipe (61) so that it faces the surface of the finished workpiece. Ensure that the air coverage range matches the material feeding requirements. Connect the air pipes of the telescopic cylinder (10) and the air blowing mechanism (6) to the air source. Complete the circuit connection between the main body of each four-axis rotary table and the control system of the machine tool (4). Finally, conduct an action test to ensure that the synchronous telescopic movement and processing action are coordinated.

[0045] When disassembling, maintaining, or replacing parts, turn off the air and power sources to ensure safe operation. Remove the connecting bolts between the air blowing pipe (61) and the mounting bracket (60), remove the air blowing mechanism (6), loosen the fixing bolts of the first feeding head (31) and the second feeding head (32), disconnect them from the turntable body, disconnect the air pipe and circuit of the telescopic cylinder (10), loosen the connecting plate (13) bolts between the synchronizing rod (14) and the connecting rod (11), and remove the entire linkage mechanism (1) from the mounting base (12). Remove the bolts from the first four-axis turntable body (21) and the second four-axis plate, remove the linkage mechanism (1) from the mounting base (12), remove the fixing bolts from the first four-axis turntable body (21) and the second four-axis turntable body (22), remove it from the machine base (4), remove the connecting parts between the mounting base (12) and the machine base (4), sort all the disassembled parts, and check whether the key parts (such as the synchronizing rod (14) and the connecting plate (13)) are intact, so as to prepare for subsequent maintenance or reassembly.

[0047] The telescopic device (10) is positioned in the middle of the two turntables, which can balance the transmission path of the driving force on both sides, ensure that the synchronous rod (14) is subjected to uniform force on the left and right sides, and avoid delay or misalignment of the action due to uneven load. The bottom is rigidly fixed to the machine base (4) through the mounting base (12), which can effectively prevent vibration or displacement caused by the telescopic device (10) during operation and enhance the overall structural stability.

[0048] Reference Appendix Figure 3 In a preferred embodiment of this utility model, the bottom of the mounting base (12) is fixed on a machine base (4), and the first four-axis turntable body (21) and the second four-axis turntable body (22) are both mounted on the machine base (4).

[0049] The mounting base (12) and the main body of the double turntable are fixed on the machine base (4), which can realize the rigid connection between the components and avoid misalignment or vibration caused by scattered installation. The machine base (4) serves as a common support base, which can ensure that the two turntables always remain parallel and aligned, thereby improving the synchronization accuracy of the linkage mechanism (1) and reducing displacement deviation caused by loose structure during processing.

[0050] Reference Appendix Figure 3 In a preferred embodiment of this utility model, a detachable connecting plate (13) is provided on the synchronizing rod (14), and the synchronizing rod (14) is connected to the connecting rod (11) through the connecting plate (13).

[0051] The detachable connecting plate (13) simplifies the assembly steps of the synchronizing rod (14) and the connecting rod (11), making it easy to adjust the spacing between components or quickly replace worn parts. Through the stable transition of the connecting plate (13), the stress concentration caused by the direct "hard" contact between the synchronizing rod (14) and the connecting rod (11) can be reduced, extending the service life and ensuring the synchronization accuracy of the linkage extension and retraction of the dual turntables.

[0053] Reference Appendix Figure 3 In a preferred embodiment of this utility model, both the first feeding head (31) and the second feeding head (32) are retractable feeding head structures.

[0054] The first loading head (31) and the second loading head (32) can form a relative motion with the processing heads of the first four-axis rotary table body (21) and the second four-axis rotary table body (22), which reduces the tolerance caused by the retraction of the loading head and the loosening during processing, and also improves the processing efficiency.

[0055] Reference Appendix Figure 8 In a preferred embodiment of this utility model, product (5) is an impeller.

[0056] Reference Appendix Figure 3 , 4 In a preferred embodiment of this utility model, an air blowing mechanism (6) for blowing down the product (5) is provided between the first four-axis turntable body (21) and the second four-axis turntable body (22).

[0057] The blowing mechanism (6) is used to blow off the product (5) that is "adhered" to the equipment after processing, and also reduces the high temperature of the freshly processed product (5), allowing it to cool down quickly.

[0058] Reference Appendix Figure 4 In a preferred embodiment of the present invention, the air blowing mechanism (6) includes a mounting bracket (60) fixed on the machine base (4) and air blowing pipes (61) respectively disposed on both sides of the mounting assembly, with the head of the air blowing pipe (61) facing the processing position of the product (5).

[0059] The air blowing mechanism (6) in this technical solution has a simple structure. It uses a mounting bracket (60) in conjunction with air blowing pipes (61) set in mirror on both sides to blow down and cool the product (5) after completing a processing action.
