[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 4 The CNC machine tool described in this application is described in detail.

[0033] refer to Figure 1 The CNC machine tool according to an embodiment of the present utility model includes a housing (not shown in the figure), a fixture 100, a worktable 200, a transport module 10, and a processing module (not shown in the figure);

[0034] The housing has a receiving cavity; the fixture 100 is detachably disposed in the receiving cavity, and the fixture 100 has multiple mounting areas 110 for placing the interchangeable plate 400; the worktable 200 is disposed in the receiving cavity and located on one side of the fixture 100, and the worktable 200 is used to place the interchangeable plate 400; the transport module 10 is disposed in the receiving cavity and is used to transport the interchangeable plate 400 between the fixture 100 and the worktable 200; the processing module is disposed in the receiving cavity and is used to process the workpiece on the interchangeable plate 400 on the worktable 200.

[0035] Furthermore, when the CNC machine tool of this application is working, the operator can load the fixture 100, which is fully loaded with interchangeable plates 400, into the receiving cavity of the housing. Then, the transfer module 10 can transfer the interchangeable plates 400 on the fixture 100 to the worktable 200. The machining module can perform CNC machining on the workpieces on the interchangeable plates 400 at the worktable 200. After all the workpieces on the interchangeable plates 400 at the worktable 200 have been machined, the transfer module 10 can transfer the interchangeable plates 400 on the worktable 200 to the mounting area 110 of the fixture 100, and transfer another interchangeable plate 400 on the fixture 100 to the worktable 200 so that the machining module can machine the workpieces on the interchangeable plates 400. After all the workpieces on the interchangeable plates 400 on the fixture 100 have been machined, the operator can open the receiving cavity of the housing, unload the fixture 100 in the receiving cavity, and load another fixture 100, which is fully loaded with interchangeable plates 400, into the receiving cavity.

[0036] It is understood that by setting a fixture 100 and a transport module 10 in the receiving cavity, multiple interchangeable plates 400 can be placed on the fixture 100, and the transport module 10 can realize the transport of the interchangeable plates 400 between the fixture 100 and the worktable 200. Thus, after the operator completes one loading of the CNC machine tool of this application, the CNC machine tool of this application can complete the CNC machining of workpieces on multiple interchangeable plates 400, thereby reducing the loading and unloading frequency of the operator on the CNC machine tool of this application, and the CNC machine tool of this application has higher processing efficiency.

[0037] In some embodiments of this utility model, reference is made to Figure 1 The transport module 10 includes a drive assembly (not shown in the figure) and a clamping assembly 300. The clamping assembly 300 is used to clamp the interchangeable plate 400. The drive assembly is connected to the clamping assembly 300 and is used to drive the clamping assembly 300 to reciprocate between the fixture 100 and the worktable 200.

[0038] Understandably, when it is necessary to transfer the interchangeable plate 400 from the fixture 100 to the worktable 200, the drive assembly can drive the clamping assembly 300 to move to the fixture 100 so that the clamping assembly 300 can clamp the interchangeable plate 400 on the fixture 100. Then, the drive assembly can drive the clamping assembly 300 to move to the worktable 200 so that the clamping assembly 300 can place the clamped interchangeable plate 400 on the worktable 200, thereby completing the transfer of the interchangeable plate 400 from the fixture 100 to the worktable 200. The transfer of the interchangeable plate 400 from the worktable 200 to the fixture 100 is achieved by the drive assembly driving the clamping assembly 300 to move to the worktable 200 so that the clamping assembly 300 can clamp the interchangeable plate 400 on the worktable 200. Then, the drive assembly driving the clamping assembly 300 to move to the fixture 100 so that the clamping assembly 300 can place the clamped interchangeable plate 400 on the fixture 100, thereby completing the transfer of the interchangeable plate 400 from the worktable 200 to the fixture 100.

[0039] In a further embodiment of the present invention, the clamping assembly 300 includes a mounting frame 310, a first driving structure 320 and two grippers 330. A clamping area for clamping the interchangeable plate 400 is formed between the two grippers 330. The first driving structure 320 is disposed on the mounting frame 310 and connected to at least one gripper 330. The first driving structure 320 is used to drive the two grippers 330 to move closer or further apart from each other.

[0040] For example, such as Figure 2As shown, the clamping assembly 300 includes a mounting frame 310, a first drive structure 320, and two grippers 330. The two grippers 330 are distributed in the left-right direction, forming a clamping area between them. The gripper 330 on the left is the first gripper 330A, and the gripper 330 on the right is the second gripper 330B. The first gripper 330A is fixedly mounted on the lower end of the mounting frame 310. The first drive structure 320 is mounted on the mounting frame 310, and its output end is connected to the second gripper 330B. The first drive structure 320 is used to drive the second gripper 330B to move closer to or further away from the first gripper 330A in the left-right direction, so that the second gripper 330B can cooperate with the first gripper 330A to clamp or release the interchangeable plate 400 in the clamping area.

[0041] Specifically, the first drive structure 320 is a cylinder, which is inexpensive and readily available.

[0042] In some embodiments of this utility model, the end of the gripper 330 near the gripping area is provided with a receiving groove 331 for accommodating the interchangeable plate 400.

[0043] For example, such as Figure 3 As shown, the right end of the first gripper 330A and the left end of the second gripper 330B are both provided with receiving grooves 331, and the receiving grooves 331 have two groove walls distributed in the front-back direction.

[0044] Understandably, after the second gripper 330B cooperates with the first gripper 330A to clamp the interchangeable plate 400, the left end of the interchangeable plate 400 can be accommodated in the receiving groove 331 of the first gripper 330A, and the right end of the interchangeable plate 400 can be accommodated in the receiving groove 331 of the second gripper 330B. Thus, the receiving groove 331 of the first gripper 330A can limit the left end of the interchangeable plate 400 in the front-back direction, and the receiving groove 331 of the second gripper 330B can limit the right end of the interchangeable plate 400 in the front-back direction, thereby enabling the clamping assembly 300 of this application to clamp the interchangeable plate 400 more firmly.

[0045] In some embodiments of this utility model, the bottom of the receiving groove 331 is provided with a support protrusion 332 extending toward the clamping area. The support protrusion 332 is used to support the interchangeable plate 400 in the vertical direction.

[0046] For example, such as Figure 3 As shown, the bottom of the receiving groove 331 of the first gripper 330A is provided with a support protrusion 332 extending to the right, and the bottom of the receiving groove 331 of the second gripper 330B is provided with a support protrusion 332 extending to the left.

[0047] Understandably, after the second gripper 330B engages with the first gripper 330A to clamp the interchangeable plate 400, the support protrusion 332 of the first gripper 330A can support the left end of the interchangeable plate 400 in the vertical direction, and the support protrusion 332 of the second gripper 330B can support the right end of the interchangeable plate 400 in the vertical direction. The provision of the support protrusion 332 reduces the probability of the interchangeable plate 400 detaching from the clamping assembly 300, thereby improving the firmness of the clamping assembly 300 in clamping the interchangeable plate 400 in this embodiment.

[0048] In some embodiments of this utility model, reference is made to Figure 4 The workbench 200 is also equipped with a locking assembly 210, which is used to lock and fix the interchangeable plate 400 on the workbench 200.

[0049] Understandably, after the transfer module 10 transfers the interchangeable plate 400 from the fixture 100 to the worktable 200, the locking assembly 210 can lock and fix the interchangeable plate 400 on the worktable 200 so that the subsequent processing module can process the workpiece on the interchangeable plate 400. After the processing module finishes processing the workpiece on the interchangeable plate 400 on the worktable 200, the locking assembly 210 can release the locking and fixing of the interchangeable plate 400 on the worktable 200. At this time, the transfer module 10 can transfer the interchangeable plate 400 on the worktable 200 to the fixture 100.

[0050] In some embodiments of this utility model, reference is made to Figure 4 The locking assembly 210 includes a second drive structure 211 and a locking member 212. The second drive structure 211 is connected to the locking member 212. The locking member 212 includes a locking part 212a. Under the drive of the second drive structure 211, the locking part 212a can approach and cooperate with the worktable 200 to clamp the interchange plate 400.

[0051] Furthermore, after the transfer module 10 transfers the interchange plate 400 from the fixture 100 to the worktable 200, under the drive of the second drive structure 211, the locking part 212a moves downward toward the worktable 200 to cooperate with the worktable 200 to clamp the interchange plate 400; when the transfer module 10 needs to transfer the interchange plate 400 from the worktable 200 to the fixture 100, the second drive structure 211 can drive the locking part 212a upward away from the worktable 200 to unlock the interchange plate 400 on the worktable 200.

[0052] In a further embodiment of this utility model, reference is made to... Figure 4The second drive structure 211 includes a driver 211a and a hinge seat 211b, with the hinge seat 211b connected to the driver 211a. The locking member 212 also includes a connecting part 212b and a hinge part 212c, with the hinge part 212c hinged to the hinge seat 211b. The connecting part 212b and the locking part 212a are respectively connected to the opposite ends of the hinge part 212c. The output end of the driver 211a is connected to the connecting part 212b and is used to drive the connecting part 212b to perform lifting and lowering movements.

[0053] Furthermore, when the locking assembly 210 needs to lock and fix the interchangeable plate 400 on the worktable 200, the driver 211a drives the connecting part 212b to rotate upward relative to the hinge part 212c, so that the locking part 212a rotates downward relative to the hinge part 212c to approach the worktable 200, and the hinge part 212c cooperates with the worktable 200 to lock and fix the interchangeable plate 400 on the worktable 200; when the locking assembly 210 needs to unlock the interchangeable plate 400 on the worktable 200, the driver 211a drives the connecting part 212b to rotate downward relative to the hinge part 212c, so that the locking part 212a rotates upward relative to the hinge part 212c to move away from the worktable 200, thereby unlocking the interchangeable plate 400 on the worktable 200.

[0054] Understandably, since the locking member 212 can rotate around the hinge portion 212c, when the locking portion 212a moves away from the interchange plate 400 on the worktable 200 in the vertical direction, the locking portion 212a can also move away from the interchange plate 400 on the worktable 200 in the horizontal direction. This allows the locking portion 212a to avoid the interchange plate 400 during the unloading process of the interchange plate 400 on the worktable 200 by the transport module 10.

[0055] In some embodiments of this utility model, the gripper 330 is provided with a clearance groove 333 for the clearance locking member 212.

[0056] Furthermore, by providing a clearance groove 333 on the gripper 330, after the transfer module 10 transfers the interchange plate 400 onto the worktable 200, the second drive structure 211 can drive the locking member 212 to move, so that the locking part 212a can pass through the clearance groove 333 and cooperate with the worktable 200 to clamp and fix the interchange plate 400. Then, the clamping assembly 300 can release the clamped interchange plate 400.

[0057] Understandably, the clearance groove 333 allows the locking component 210 to lock and fix the interchange plate 400 on the worktable 200 after the transfer module 10 transfers the interchange plate 400 onto the worktable 200. Then, the clamping component 300 of the transfer module 10 can release the clamped interchange plate 400, thereby reducing the probability of the interchange plate 400 shifting on the worktable 200.

[0058] In some embodiments of this utility model, reference is made to Figure 4 The workbench 200 is provided with two locking components 210, which are distributed in the left and right directions and are used to cooperate with the workbench 200 to clamp and fix the left and right ends of the interchangeable plate 400.

[0059] In some embodiments of this utility model, reference is made to Figure 1 Each installation area 110 is provided with multiple positioning posts 111, which are used to pass through the positioning holes of the interchange plate 400.

[0060] It is understandable that by providing a positioning post 111 in the installation area 110, when the interchangeable plate 400 is placed in the installation area 110, the positioning post 111 can pass through the positioning hole of the interchangeable plate 400 to achieve positioning of the interchangeable plate 400.

[0061] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
