[0026] The first embodiment

[0027] Please refer to Figures 1-3 , an embodiment of one aspect of the present utility model provides a workpiece processing device, including a fixed seat 10, a loading fixture 20, a first driving mechanism 30, a second driving mechanism 40, a third driving mechanism 50, and a fourth driving mechanism 60. The fixed seat 10 is used to fix a milling cutter; the loading fixture 20 is used to place a workpiece, and the loading fixture 20 has a central axis 21; the first driving mechanism 30 includes a first running shaft 31 and a first driver 32; the second driving mechanism 40 is slidably connected to the first running shaft 31, and the first driver 32 drives the second driving mechanism 40 to move along the first running shaft 31. The second driving mechanism 40 includes a second running shaft 41 and a second driver 42. The fixed seat 10 is slidably connected to the second running shaft, and the second driver 42 is used to drive the fixed seat 10 to move along the first running shaft 31; the third driving mechanism 50 includes a third running shaft 51 and a third driver 52; the fourth driving mechanism 60 is rotatably connected to the loading fixture 20 to drive the loading fixture 20 to rotate around the central axis 21; the fourth driving mechanism 60 is slidably connected to the third running shaft 51, and the third driver 52 is used to drive the fourth driving mechanism 60 to move along the third running shaft 51; the first running shaft 31, the second running shaft 41, and the third running shaft 51 are perpendicular to each other pairwise. Preferably, the central axis 21 is parallel to the first running shaft 31.

[0028] Specifically, the fixed seat 10 is slidably connected to the first operating shaft 31. Driven by the first driver 32, the fixed seat 10 drives the milling cutter to slide along the first operating shaft 31. On this basis, the first driving mechanism 30 is slidably connected to the second operating shaft 41. Driven by the second driver 42, the first driving mechanism 30 drives the milling cutter to slide along the second operating shaft 41, that is, the milling cutter can move in the directions of the first operating shaft 31 and the second operating shaft 41. The loading fixture 20 is rotatably connected to the fourth driving mechanism 60. Driven by the fourth driving mechanism 60, the loading fixture 20 drives the workpiece to rotate around the central axis 21 of the loading fixture 20. At the same time, the fourth driving mechanism 60 is slidably connected to the third operating shaft 51. Driven by the third driver 52, the fourth driving mechanism 60 drives the loading fixture 20 and the workpiece to slide along the third operating shaft 51, that is, the workpiece can move in the direction of the third operating shaft 51 and can rotate in space. The first operating shaft 31, the second operating shaft 41, and the third operating shaft 51 are perpendicular to each other pairwise, so that the milling cutter and the workpiece can move relative to each other in three different directions, and the workpiece can be simply processed in three-dimensional space. Moreover, the movements of the milling cutter and the workpiece are independent of each other, avoiding the mechanical complexity caused by the layered superposition of driving components when the milling cutter is moved alone in the prior art, reducing the difficulty of setting the driving components and the driving burden of the driving devices. In addition, the workpiece can be spatially flipped, so that the milling cutter can machine different surfaces of the workpiece, and can also engrave various curved paths in the workpiece, enabling the same milling equipment to perform various types of workpiece processing processes, improving the flexibility and versatility of the equipment.

[0029] In this embodiment, the fixed seat 10 is located above the third driving mechanism 50. As the fourth driving mechanism 60 slides along the third operating shaft 51, the loading fixture 20 aligns with or deviates from the fixed seat 10.

[0030] Specifically, when loading the workpiece, for the convenience and efficiency of loading, manual labor or loading equipment tends to load the workpiece to the edge of the workpiece processing device, and then the third driving mechanism 50 pushes the workpiece to the specific position for actual processing. Since the workpiece is located within the fourth driving mechanism 60, the third driver 52 only needs to drive the fourth driving mechanism 60 to send the workpiece under the milling cutter on the fixed seat 10, or to withdraw the processed workpiece product from the milling cutter station and send it back to the original loading station for convenient unloading of the product.

[0031] In this embodiment, a vision guiding mechanism is further included. The vision guiding mechanism is disposed on the fixed seat 10 and is used to determine the shape and position of the workpiece on the loading fixture 20.

[0032] Specifically, the vision guiding mechanism and the milling cutter move together with the fixed seat 10, so as to be able to understand the workpiece condition under the milling cutter in real time and provide the parameters of the workpiece for the control of the milling cutter, which is beneficial to the precise control of the milling cutter and improves the machining accuracy of the workpiece. The vision guiding mechanism can obtain the shape characteristics and position characteristics of the workpiece by taking pictures or videos, and convert them into a coordinate system, which is used to provide a precise path for the machining movement of the milling cutter and the workpiece.

[0033] In this embodiment, the feeding jig 20 is provided with a first connecting member 22 and a rotating seat 24 along the direction of its central axis 21. The rotating seat 24 is rotationally connected to the fourth driving mechanism 60 through the first connecting member 22, and the rotating seat 24 is used to drive the workpiece to rotate.

[0034] Specifically, the first connecting member 22 can specifically be a bearing, which improves the connection lubricity between the feeding jig 20 and the fourth driving mechanism 60. In the direction of the central axis 21, the first connecting member 22 is preferably arranged at one end of the rotating seat 24. The fourth driving mechanism 60 drives the first connecting member 22 to rotate, thereby driving the rotation of the rotating seat 24. At this time, the first connecting member 22 and the rotating seat 24 can jointly rotate around the central axis 21 of the feeding jig 20 under the drive of the fourth driving mechanism 60, and the transmission is more direct, and the connection of the structure can also be more concise.

[0035] In this embodiment, the feeding jig 20 further has a second connecting member 23. The first connecting member 22 and the second connecting member 23 are arranged at both ends of the rotating seat 24 and are both rotationally connected to the fourth driving mechanism 60.

[0036] Specifically, both ends of the rotating seat 24 in the direction of the central axis 21 of the feeding jig 20 are connected to the fourth driving mechanism 60, which disperses the gravity of the rotating seat 24, makes the rotating seat 24 more balanced on the fourth driving mechanism 60, avoids the problem of single stress point caused by single-sided connection, makes the structure more stable, and the service life can also be extended accordingly. Both the first connecting member 22 and the second connecting member 23 can be bearings, which are used to improve the transmission of rotational power and the lubricity of rotation.

[0037] In this embodiment, the third operating shaft 51 includes a driving track 511 and a bearing track 512. The bearing track 512 is arranged parallel to the driving track 511. The fourth driving mechanism 60 includes a fourth driver 61 and a transmission 62. The fourth driver 61 is connected to the first connecting member 22 to drive the feeding jig 20 to rotate. The transmission 62 is connected to the second connecting member 23 to balance the force of the fourth driving mechanism 60. The fourth driver 61 is slidably connected to the driving track 511, and the transmission 62 is slidably connected to the bearing track 512.

[0038] Specifically, the fourth driver 61 is connected to the first connecting member 22 on one side to support the gravity of the feeding jig 20 and drive its rotation. This will cause an excessive burden on the fourth driver 61, and the connection with the first connecting member 22 is prone to brittle fracture due to long-term load-bearing and frequent rotation. Therefore, a transmission 62 is provided on the opposite side of the fourth driver 61 to connect the second connecting member 23, so that the gravity of the feeding jig 20 is dispersed on both sides of the fourth driving mechanism 60, making the overall structure more balanced and stable in force. The space position of the fourth driving mechanism 60 between the fourth driver 61 and the transmission 62 in the fourth driving mechanism 60 is elongated. Therefore, using only one track during the sliding process may lead to unstable support. Thus, the third running shaft 51 is provided with a driving track 511 and a bearing track 512 arranged in parallel, enabling the fourth driving mechanism 60 to operate more smoothly.

[0039] In this embodiment, the fourth driving mechanism 60 further includes a support base 63 for supporting the fourth driver 61 and the transmission 62. The support base 63 is symmetrically provided with a first sliding groove 631 and a second sliding groove 632. The fourth driver 61 is arranged corresponding to the first sliding groove 631, and the transmission 62 is arranged corresponding to the second sliding groove 632. The first sliding groove 631 is slidably connected to the driving track 511, and the second sliding groove 632 is slidably connected to the bearing track 512.

[0040] Specifically, the driving track 511 is mainly used to support the pressure on the side close to the fourth driver 61, and the bearing track 512 is mainly used to support the pressure on the side close to the transmission 62. Due to the differences in structure and function, the pressure of the fourth driver 61 on the track may be greater than that of the transmission 62 on the track. Preferably, the structural strength of the driving track 511 is greater than that of the bearing track 512, or the width of the driving track 511 is larger than the width of the bearing track 512.

[0041] In this embodiment, the fourth driving mechanism 60 further includes a limiter 64. The rotating seat 24 is detachably connected to the limiter 64, and the limiter 64 is connected to the support base 63. The limiter 64 is preferably fixed to the support base 63. The rotating seat 24 is rotatably connected to the fourth driver 61. When the rotating seat 24 is separated from the limiter 64, the limiter 64 avoids the rotation of the rotating seat 24. When the rotating seat 24 is connected to the limiter 64, the limiter 64 restricts the rotation of the rotating seat 24.

[0042] Specifically, when the rotating seat 24 is fixedly connected to the limiter 64, the workpiece located on the rotating seat 24 can be stably machined by the milling cutter without rotating due to the action of the milling cutter. When the workpiece needs to be flipped and turned, it needs to be separated from the limiter 64 before rotation.

[0043] Further, the stopper 64 further includes a fifth driver and a slideway. The rotating seat 24 is slidably connected to the slideway. The fifth driver is used to drive the rotating seat 24 to move along the slideway. With the drive of the fifth driver, the rotating seat 24 is located on the slideway and restricted by the slideway, or the rotating seat 24 slides out of the slideway and separates from the stopper 64. At this time, the rotating seat 24 is not restricted by the stopper 64 and can rotate relative to the stopper 64.

[0044] In this embodiment, the rotating seat 24 further includes a rotating table 241 and a placing table 242. The rotating table 241 is rotatably connected to the fourth driving mechanism 60. The rotating table 241 is provided with a first slide rail 241a and a second slide rail 241b that are perpendicular to each other. The placing table 242 is used to carry the workpiece. Both the first slide rail 241a and the second slide rail 241b are slidably connected to the placing table 242.

[0045] Specifically, when the rotating seat 24 completes the flipping and surface-changing, by moving the placing table 242 relative to the rotating table 241, the workpiece located on the placing table 242 can be moved in a direction different from the first operating axis 31, the second operating axis 41, and the second operating axis 41, further improving the freedom and versatility of workpiece processing.

[0046] The workpiece processing device provided by the present utility model, by setting the first operating axis 31, the second operating axis 41, and the third operating axis 51 in different directions, enables the fixed seat 10 to drive the milling cutter to move in three different directions. Additionally, by setting a fourth driving mechanism 60, the loading jig 20 can drive the workpiece to rotate around the central axis 21 of the loading jig 20. The workpiece and the milling cutter can move independently, solving the problem caused by the limitation of milling cutter control, thereby increasing the freedom and flexibility of workpiece processing and being applicable to more processing techniques.

[0048] Please refer to Figure 4 , another embodiment of the present utility model provides a numerical control machine tool, including a plurality of workpiece processing devices as described in the first embodiment, and the plurality of workpiece processing devices are arranged along the first operating axis 31.

[0049] Specifically, when the plurality of workpiece processing devices are arranged in parallel along the first operating axis 31, the plurality of first operating axes 31 in the plurality of workpiece processing devices are connected to each other, improving the structural regularity of the numerical control machine tool, and the distance of the loading station can be closer, improving the loading efficiency.

[0050] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
