Description

Technical Field

[0001] This utility model relates to the field of automated machining technology, and in particular to a five-axis linkage machining center. Background Technology

[0002] Existing five-axis machining centers typically employ one of two approaches: one is a gantry crane structure, which uses a gantry to mount the Y, X, and Z axes to control the machining mechanism with the B axis, thereby allowing the machining mechanism to move relative to the carrier and achieve high-precision machining results. For details, please refer to Chinese Utility Model Patent No. CN202420139257.4. The other approach is to add two additional axes to the basic three-axis structure to achieve a low-cost five-axis linkage effect. For details, please refer to Chinese Utility Model Patent No. CN202322824885.4.

[0003] Of the two solutions mentioned above, the first solution has high precision, but its cost is also very high due to considerations such as stability; while the second solution has low cost but suffers from a greater loss of precision, which is not conducive to precision-machined products. Summary of the Invention

[0004] This invention addresses the problems of existing technologies by providing a five-axis linkage machining center that effectively reduces costs while achieving high-precision five-axis linkage.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a five-axis linkage machining center, including a machine body, a machining mechanism, a carrier, a Y-axis module, an X-axis module, and a Z-axis module. The Y-axis module and the X-axis module are both disposed on the machine body. The Y-axis module is driven and connected to the carrier, the X-axis module is driven and connected to the Z-axis module, and the Z-axis module is driven and connected to the machining mechanism, which is located above the carrier.

[0006] Furthermore, the X-axis module includes a mounting platform, an X-axis motor, an X-axis lead screw, and an X-axis slide. The mounting platform is mounted on the machine body, the X-axis lead screw is rotatably mounted on the mounting platform, the X-axis motor drives and connects to the X-axis lead screw, the X-axis slide is slidably mounted on the mounting platform and screwed to the X-axis lead screw, and the Z-axis module is mounted on the X-axis slide.

[0007] Furthermore, the X-axis motor, X-axis lead screw, and X-axis slide are all located on the top of the mounting platform, and the machining mechanism is located on one side of the X-axis slide.

[0008] Furthermore, the Z-axis module includes a Z-axis motor, a Z-axis lead screw, and a Z-axis slide. The Z-axis motor is mounted on the X-axis slide, the Z-axis lead screw is rotatably mounted on the X-axis slide, the Z-axis motor drives and connects to the Z-axis lead screw, the Z-axis slide is screwed to the Z-axis lead screw, and the machining mechanism is mounted on the Z-axis slide.

[0009] Furthermore, the carrier includes a base, a tilting motor, and a main body. The base is slidably disposed on the machine body and driven and connected by the Y-axis module. The main body is rotatably disposed on the base. The tilting motor is used to drive the main body to rotate around the driving direction of the Y-axis module. The main body is used to fix the product to be processed.

[0010] Furthermore, the Y-axis module includes a Y-axis motor, a Y-axis lead screw, and a Y-axis slider. The machine body is provided with a guide rail. The Y-axis slider is mounted on the carrier and slidably disposed on the guide rail. The Y-axis lead screw is rotatably disposed on the machine body. The Y-axis motor drives and connects to the Y-axis lead screw. The carrier is screwed to the Y-axis lead screw.

[0011] Furthermore, the machining mechanism includes a machining base, a machining motor, and a machining table. The machining base is mounted on the output end of the Z-axis module, the machining motor is mounted on the machining base, and the machining table is mounted on the output end of the machining motor. The machining table is used to assemble cutting tools.

[0012] Furthermore, the machine body is also equipped with a tool magazine, a tool changer motor, a tool changer, and a tool holder motor. The tool magazine is installed on the machine body and is used to store tools of different specifications. The tool changer motor is used to drive the tool magazine to rotate. The tool changer is used to pick up tools from the tool magazine and the machining mechanism. The tool holder motor is used to drive the tool changer to rotate.

[0013] Furthermore, the cutting tool rotates around the transmission direction of the Y-axis module, and the bottom of the tool magazine is provided with a tool outlet; the machine body is also provided with a lifting module, which is used to drive the tool changer to lift and lower, so that the tool changer can enter and exit the tool outlet to pick up and put in the cutting tool.

[0014] The beneficial effects of this utility model are as follows: This utility model drives the machining mechanism through the X-axis module and Z-axis module, and drives the carrier through the Y-axis module, so that the load of each module is not too large, thereby reducing the cost by reducing the load; at the same time, since the structure and drive of this utility model are similar to those of an overhead crane, the loss of precision is small and it is easy to popularize and use.

Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, the present invention provides a five-axis linkage machining center, including a machine body 1, a machining mechanism 2, a carrier 3, a Y-axis module 4, an X-axis module 5, and a Z-axis module 6. The Y-axis module 4 and the X-axis module 5 are both disposed on the machine body 1. The Y-axis module 4 is driven and connected to the carrier 3, the X-axis module 5 is driven and connected to the Z-axis module 6, and the Z-axis module 6 is driven and connected to the machining mechanism 2. The machining mechanism 2 is located above the carrier 3.

[0021] Specifically, this invention does not use a gantry frame. Instead, it utilizes the X-axis module 5 to drive the Z-axis module 6 to move along the X-direction, i.e., horizontally towards or away from the carrier 3. The Z-axis module 6 then drives the machining mechanism 2 mounted on it to move vertically towards or away from the carrier 3. The Y-axis module 4 drives the carrier 3 to move along the Y-axis, causing it to move horizontally along the Y-axis direction perpendicular to the driving direction of the Y-axis module 4. By using the X-axis module 5 and Z-axis module 6 to drive the machining mechanism 2, and the Y-axis module 4 to drive the carrier 3, the burden on the modules driving the machining mechanism 2 is reduced, thus eliminating the need for excessive stabilizing structures and reducing costs. In actual use, this utility model operates as follows: the operator directly mounts the product onto the carrier 3 and then starts the utility model. Based on a preset trajectory, the utility model, through the coordinated control of the X-axis module 5, Y-axis module 4, and Z-axis module 6, controls the positional changes of the processing mechanism 2 relative to the carrier 3 in three-dimensional space. Then, by utilizing the fact that the carrier 3 itself can be flipped and the processing mechanism 2 can be rotated, a five-axis linkage processing method is formed.

[0022] In this embodiment, the X-axis module 5 includes a mounting platform 51, an X-axis motor 52, an X-axis lead screw 53, and an X-axis slide 54. The mounting platform 51 is mounted on the machine body 1, the X-axis lead screw 53 is rotatably mounted on the mounting platform 51, the X-axis motor 52 drives and connects to the X-axis lead screw 53, the X-axis slide 54 is slidably mounted on the mounting platform 51 and screwed to the X-axis lead screw 53, and the Z-axis module 6 is mounted on the X-axis slide 54.

[0023] Specifically, the X-axis motor 52 is preferably a servo motor. The mounting platform 51 ensures that the horizontal height of the X-axis module 5 is higher than that of the carrier 3, thus positioning the machining mechanism 2 above the carrier 3. The X-axis motor 52, in conjunction with the X-axis lead screw 53, drives the X-axis slide 54 to move with high precision, achieving a finishing effect and ensuring the accuracy of the relative movement distance between the machining mechanism 2 and the carrier 3 along the X-axis.

[0024] Specifically, the X-axis motor 52, X-axis lead screw 53, and X-axis slide 54 are all located on top of the mounting platform 51, and the machining mechanism 2 is located on one side of the X-axis slide 54. That is, the mounting platform 51 is simply a platform protruding from the machine body 1, mainly to create a height difference between the X-axis module 5 and the Y-axis module 4, thereby making the machining mechanism 2 and the carrier 3 have a height difference, which facilitates machining.

[0025] Specifically, the Z-axis module 6 includes a Z-axis motor 61, a Z-axis lead screw 62, and a Z-axis slide 63. The Z-axis motor 61 is mounted on the X-axis slide 54, the Z-axis lead screw 62 is rotatably mounted on the X-axis slide 54, the Z-axis motor 61 drives and connects to the Z-axis lead screw 62, the Z-axis slide 63 is screwed to the Z-axis lead screw 62, and the machining mechanism 2 is mounted on the Z-axis slide 63.

[0026] The Z-axis motor 61 is preferably a servo motor, which is driven by the Z-axis module 6 to enable the machining mechanism 2 to move up and down with high precision, thereby ensuring sufficient machining accuracy in the vertical direction.

[0027] In this embodiment, the carrier 3 includes a base 31, a tilting motor 32, and a main body 33. The base 31 is slidably mounted on the machine body 1 and driven and connected by the Y-axis module 4. The main body 33 is rotatably mounted on the base 31. The tilting motor 32 drives the main body 33 to rotate around the driving direction of the Y-axis module 4. The main body 33 is used to fix the product to be processed. The main body 33 is a structure for fixing the product and can be fixed by conventional structures such as screws and locks, which will not be described further here. The tilting motor 32 drives the main body 33, which is rotatably mounted on the base 31, to tilt. The tilting is centered on the driving direction of the Y-axis module 4, thereby changing the position of the product on the main body 33 facing the processing mechanism 2, allowing for a more comprehensive processing flow.

[0028] In this embodiment, the Y-axis module 4 includes a Y-axis motor 41, a Y-axis lead screw 42, and a Y-axis slider 43. The machine body 1 is provided with a guide rail 12. The Y-axis slider 43 is mounted on the carrier 3 and slidably disposed on the guide rail 12. The Y-axis lead screw 42 is rotatably disposed on the machine body 1. The Y-axis motor 41 drives and connects to the Y-axis lead screw 42. The carrier 3 is screwed to the Y-axis lead screw 42.

[0029] The specific structure and function of the Y-axis module 4 can be referenced from the X-axis module 5. The difference between the two is that the Y-axis module 4 drives the carrier 3, while the X-axis module 5 drives the machining mechanism 2.

[0030] In this embodiment, the machining mechanism 2 includes a machining base 21, a machining motor 22, and a machining table 23. The machining base 21 is installed at the output end of the Z-axis module 6, the machining motor 22 is installed at the machining base 21, and the machining table 23 is installed at the output end of the machining motor 22. The machining table 23 is used to assemble cutting tools.

[0031] In this embodiment, the structure is actually used for CNC machine tools. The machining motor 22 is used to drive the machining table 23 to rotate around the driving direction of the X-axis module 5. That is, the driving direction of the machining motor 22 and the driving direction of the flip motor 32 are perpendicular to each other, so that the tool can rotate at high speed to achieve the cutting effect on the product.

[0032] Specifically, the machining table 23 is equipped with a structure for holding the corresponding cutting tools. This structure is a conventional structure in this field and will not be described in detail here.

[0033] In this embodiment, the machine body 1 is also provided with a tool magazine 7, a tool changer motor 8, a tool changer 9, and a tool holder motor 10. The tool magazine 7 is installed on the machine body 1 and is used to store tools of different specifications. The tool changer motor 8 is used to drive the tool magazine 7 to rotate. The tool changer 9 is used to pick up the tools from the tool magazine 7 and the machining mechanism 2. The tool holder motor 10 is used to drive the tool changer 9 to rotate.

[0034] In actual use, the cutting tool rotates around the transmission direction of the Y-axis module 4, and the bottom of the tool magazine 7 is provided with a tool outlet 11; the machine body 1 is also provided with a lifting module, which is used to drive the tool changer 9 to lift and lower, so that the tool changer 9 can enter and exit the tool outlet 11 to pick up and put in the cutting tool.

[0035] Specifically, the tool magazine 7 should also have a corresponding structure for clamping the tool (not shown in the figure), and a corresponding lifting module (not shown in the figure) is also provided between the tool changer 9 and the tool holder motor 10. Since this structure has been disclosed in the prior art (for example, the solution disclosed in patent number CN202322824885.4) and is not within the scope of protection of this application, it will not be shown. During tool changing, the tool magazine 7 controls the tool changer motor 8 to rotate so that the tool magazine 7 is located at the lowest tool outlet 11. Then, the clamping structure releases the tool so that the tool falls onto the tool changer 9, and the tool of the machining mechanism 2 is also released and falls onto the tool changer 9. Then, the tool changer motor 8 is activated to swap the two tools. Finally, the machining mechanism 2 picks up the required tool and the clamping structure re-clamps the tool now located at the tool outlet 11, thus achieving the effect of automated tool changing.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
