Description

Technical Field

[0001] This utility model relates to the field of five-axis rotary table technology, and specifically to an automatic clamping structure for a five-axis rotary table. Background Technology

[0002] In the field of modern precision manufacturing, the five-axis rotary table plays a crucial role as a core component of machining centers. The working principle of a five-axis rotary table is based on the synergistic action of a rotary mechanism and a gyratory mechanism, enabling precise machining of workpieces from various angles and meeting diverse and complex machining needs. Specifically, the workpiece is securely clamped onto the table of the fifth axis using a fixture or jig. The gyratory mechanism drives the workpiece to tilt or oscillate around the fourth axis, while the rotary mechanism drives the workpiece to rotate circumferentially around the fifth axis. This complex combination of spatial motions allows the five-axis rotary table to efficiently machine workpieces with complex curved surfaces and precise geometric shapes.

[0003] However, despite the excellent machining performance of five-axis rotary tables, some shortcomings remain in workpiece clamping. Currently, most five-axis rotary table fixtures still rely on manual loading and locking of workpieces. This traditional manual operation method is not only inefficient and limits the overall capacity of the production line, but also increases the labor intensity of operators, which is detrimental to the long-term stable operation of the production line and the occupational health of employees.

[0004] With the rapid development and intelligent upgrading of the manufacturing industry, higher requirements are being placed on the automation and intelligence levels of production lines. Therefore, developing an automatic clamping structure with a five-axis rotary table that can replace manual labor is particularly important. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides an automatic clamping structure for a five-axis rotary table, which can at least solve the technical problem of wire entanglement between the rotating device 2 and the workpiece clamp or workpiece fixture on the working plate 1.

[0042] See Figure 1 and Figure 2 As shown, Figure 1 This is a first-view perspective perspective view of the automatic clamping structure on a five-axis rotary table in the embodiment. Figure 2The image shows a cross-sectional view of the automatic clamping structure on a five-axis rotary table in the embodiment. The automatic clamping structure of the five-axis rotary table includes a first power slip ring 4, a power line 5, and a first connector 6.

[0043] The five-axis rotary table includes a worktable 1, a rotating device 2, and a oscillating device 3. The worktable 1 is used to mount workpiece fixtures or workpiece jigs. The rotating device 2 is driven by the worktable 1 and is used to drive the worktable 1 to rotate around the fifth axis. The oscillating device 3 is driven by the rotating device 2 and is used to drive the rotating device 2 to oscillate around the fourth axis.

[0044] The first power slip ring 4 is mounted on the rotating device 2 and connected to the working plate 1. The working plate 1 has a first channel 11. The first power slip ring 4 is connected to the input end of the first channel 11, and the output end of the first channel 11 is used to connect to the workpiece fixture or workpiece jig on the working plate 1.

[0045] The power line 5 is installed on the rotating device 2.

[0046] The first connector 6 is installed on the swing device 3 and is used to connect to an external power source.

[0047] The input end of the power line 5 passes through the swing device 3 and is connected to the first connector 6. The output end of the power line 5 is connected to the first power slip ring 4 to transmit power to the rotating device 2 and the workpiece clamp or workpiece fixture on the working plate 1.

[0048] The automatic clamping structure described above is applicable to any five-axis rotary table and can transmit power to the workpiece clamps or fixtures on the worktable 1, enabling the workpiece clamps or fixtures to automatically clamp the workpieces, replacing manual workpiece locking, thereby effectively improving production efficiency and enhancing the automation level of the production line. The specific process of power transmission for workpiece clamping in this automatic clamping structure is as follows: an external power source transmits power to the first power slip ring 4 sequentially through the first connector 6 and power line 5. The first power slip ring 4 then transmits power to the workpiece clamps or fixtures on the worktable 1 through the first channel 11, realizing the clamping or releasing operation of the workpiece. After the external power source transmits power to the first power slip ring 4, the first power slip ring 4 can not only transmit power to the workpiece clamps or fixtures on the worktable 1, but also transmit power to the rotating device 2, realizing the rotational movement of the workpiece. It can also effectively prevent the wiring of the rotating device 2 and the workpiece clamps or fixtures on the worktable 1 from becoming entangled, thereby ensuring the stability and safety of power transmission between the rotating device 2 and the workpiece clamps or fixtures on the worktable 1.

[0049] This automatic clamping structure is applicable to any workpiece fixture or workpiece jig. Therefore, a five-axis rotary table with this automatic clamping structure can install any workpiece fixture or workpiece jig on the worktable 1 according to production needs. This automatic clamping structure greatly improves the applicability of the five-axis rotary table so as to position workpieces of different sizes or shapes.

[0050] The power provided by the aforementioned external power source can be compressed air, liquid, or electricity, etc., and the power line 5 can be designed accordingly as a gas pipeline, fluid pipeline, or cable, etc., and the first power slip ring 4 can be designed accordingly as a gas slip ring, liquid slip ring, or electric slip ring, etc., and the first channel 11 can be used to introduce gas, fluid, or cable, etc., thereby achieving the function of transmitting power. In this embodiment, the first power slip ring 4 is a gas slip ring, and the power line 5 is a gas pipe.

[0051] See Figure 3 As shown, Figure 3 The diagram shows a cross-sectional view of the automatic clamping structure on a five-axis rotary table in one embodiment. In one implementation of the first power slip ring 4, the first power slip ring 4 includes a first stator 41 and a first rotor 42 coaxially distributed. The rotating device 2 includes a rotating table 21, and the working disk 1 includes a rotating shaft 12, with a first channel 11 located on the rotating shaft 12. The first stator 41 is fixed within the rotating table 21 by screwing or welding, and the first rotor 42 is fixed to the output end of the rotating table 21 by screwing or welding. The first rotor 42 is also coaxially fixed to the rotating shaft 12 by screwing or welding. Thus, the first stator 41 and the first rotor 42 can rotate relative to each other without restriction, ensuring synchronous rotation between the working disk 1 and the output end of the rotating table 21. Simultaneously, it can transmit power to the first channel 11 and prevent the wiring of the workpiece clamps or workpiece fixtures on the rotating device 2 and the working disk 1 from becoming entangled.

[0052] The rotating stage 21 described above can use the rotary drive mechanism of an existing five-axis rotary stage to drive the work plate 1 to rotate.

[0053] See Figure 1 , Figure 2 and Figure 3As shown, based on the above embodiment, the automatic clamping structure of the five-axis rotary table further includes a second power slip ring 7. The rotating device 2 also includes a first swing arm 22 and a second swing arm 23. The swinging device 3 includes a support housing 31 and a swinging drive mechanism (not shown in the figure). The first swing arm 22 and the second swing arm 23 are fixed to both sides of the rotary table 21 by integral connection or welding, and both the first swing arm 22 and the second swing arm 23 are rotatably connected to the support housing 31. The swinging drive mechanism is installed in the support housing 31 and is drivenly connected to the first swing arm 22. The swinging drive mechanism is used to drive the rotating device 2 to swing around the fourth axis. The second power slip ring 7 is installed on the support housing 31 and connected to the second swing arm 23. The second power slip ring 7 is used to rotatably connect the second swing arm 23 and the support housing 31. The second swing arm 23 has a fixture mounting surface 231 for mounting workpiece fixtures. The fixture mounting surface 231 is arranged parallel to or inclined to the axis of the worktable 1. Thus, the automatic clamping structure of the five-axis rotary table can install workpiece fixtures on the fixture mounting surface 231 according to production needs, and use them in conjunction with the workpiece fixtures or workpiece jigs installed on the worktable 1 to meet the processing requirements of needing to clamp workpieces with both workpiece fixtures and workpiece jigs at the same time, or needing to clamp workpieces with two workpiece fixtures at the same time.

[0054] The aforementioned swing drive mechanism can use the existing swing drive mechanism of a five-axis rotary table.

[0055] See Figure 3 As shown, in one embodiment of the second power slip ring 7, the second power slip ring 7 includes a second stator 71 and a second rotor 72 coaxially distributed. The second stator 71 is fixed to the support housing 31 by means of screwing or welding, and the second rotor 72 is fixed to the second swing arm 23 by means of screwing or welding. The automatic clamping structure of the five-axis rotary table also includes a second connector 8. The second connector 8 is installed on the second power slip ring 7 and is used to connect to an external power source. The second swing arm 23 has a second channel 232. The input end of the second channel 232 is connected to the second power slip ring 7, and the output end is used to connect to the workpiece clamp on the clamp mounting surface 231 to transmit power to the workpiece clamp on the clamp mounting surface 231. In this way, the second stator 71 and the second rotor 72 can rotate relative to each other without restriction. This not only allows them to rotatably connect the rotating device 2 and the support housing 31, ensuring that the workpiece clamp on the fixture mounting surface 231 can swing synchronously with the rotating device 2, but also allows them to transmit power to the workpiece clamp on the fixture mounting surface 231 and prevent the workpiece clamp on the fixture mounting surface 231 from getting tangled with the wiring of other devices.

[0056] The external power source connected to the second connector 8 can be compressed air, liquid, or electricity, etc., and the second power slip ring 7 can be designed accordingly as a pneumatic slip ring, a liquid slip ring, or an electric slip ring, etc., and the second channel 232 can be used to pass in compressed air, liquid, or cables, etc., thereby achieving the function of transmitting power. In this embodiment, the second power slip ring 7 is a pneumatic slip ring.

[0057] See Figure 1 , Figure 2 and Figure 3 As shown, in one installation method of the power line 5, the first connector 6 is provided on the outer wall of the support housing 31 by means of screw connection or integral connection. The rotation axis of the first swing arm 22 has a clearance channel 221 that communicates with the inside of the support housing 31. The input end of the power line 5 passes through the clearance channel 221 and the support housing 31 in sequence and communicates with the first connector 6. In this way, the power line 5 on the rotating device 2 is connected to the first connector 6 on the support housing 31 through the clearance channel 221. Since the clearance channel 221 is located on the rotation axis of the first swing arm 22 and does not change position with the rotation of the first swing arm 22, the clearance channel 221 can restrict the position of the power line 5 in the support housing 31, and play a role in preventing the power line 5 from getting entangled with the swing device 3 in the support housing 31 as the rotating device 2 swings.

[0058] See Figure 1 , Figure 2 and Figure 3 As shown, based on the above embodiment, the automatic clamping structure of the five-axis rotary table also includes a third connector 9. The third connector 9 is provided on the outer wall of the support housing 31 by means of screw connection or integral connection. The third connector 9 is connected to the swing drive mechanism and is used to connect to an external power source to transmit power to the swing drive mechanism. In this way, the swing drive mechanism can be directly connected to an external power source through the third connector 9, and the power is transmitted to the rotating device 2 and the working plate 1 through different connectors, effectively preventing the wiring of the swing device 3, the rotating device 2 and the workpiece clamp or workpiece fixture on the working plate 1 from getting tangled, thereby ensuring the stability and safety of the power transmission of the swing device 3, the rotating device 2 and the workpiece clamp or workpiece fixture on the working plate 1.

[0059] The external power source connected to the third connector 9 can be powered by compressed air, liquid, or electricity, so that the swing drive mechanism can drive the rotating device 2 to swing around the fourth axis by means of pneumatic, hydraulic, or electric means.

[0060] See Figure 1 and Figure 2As shown, based on any of the above embodiments, the automatic clamping structure of the five-axis rotary table also includes a robotic arm (not shown in the figure). The robotic arm is mounted on the rotating device 2. The rotating device 2 has a robotic arm mounting surface 24, and the robotic arm mounting surface 24 has a robotic arm interface 241 for mounting the robotic arm. In this way, the rotating device 2 can install different models of robotic arm equipment according to production needs through the robotic arm interface 241. The robotic arm equipment, in conjunction with workpiece clamps and / or workpiece fixtures, can realize automatic loading and unloading of workpieces, replacing manual loading and unloading of workpieces, further improving production efficiency and the automation level of the production line, thereby realizing unmanned production.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
