Technical Field

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

[0002] A machining center is a high-precision, high-efficiency machining equipment controlled by a computer numerical control (CNC) system. It integrates multiple processes such as milling, drilling, tapping, and chamfering, enabling the machining of workpieces with various complex shapes. The main characteristics of a machining center include: high precision, high efficiency, multi-functionality, high flexibility, and a high degree of automation. Utilizing a digital control system, it achieves high-precision machining, ensuring the dimensional accuracy and surface quality requirements of the machined parts. It also features automatic tool changing, automatic clamping, and automatic measurement functions, enabling continuous, high-speed machining and improving production efficiency. Furthermore, the machining process can be controlled through programming, offering high flexibility and adaptability to meet the machining needs of different workpieces.

[0003] When machining centers (such as CNC engraving machines) process parts, they generate a large amount of waste material and cutting fluid due to milling, drilling, tapping, and other operations. In existing technology, grooves are usually set on both sides of the base surface of the machining center to collect the waste material and cutting fluid. However, in order to avoid affecting the processing, the machining center needs to be stopped and cleaned when a certain amount of waste material and cutting fluid accumulates in the grooves. This leads to low utilization of the machining center, resulting in low processing efficiency and affecting the company's production. Utility Model Content

[0032] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Please see Figures 1 to 3A multi-axis precision carving machining center includes a base 100, a crossbeam assembly 200, a slide assembly 300, a worktable 400, and a tool magazine assembly 500. The crossbeam assembly 200 is mounted on the base 100, and the slide assembly 300 is movably connected to the crossbeam assembly 200. The crossbeam assembly 200 can drive the slide assembly 300 to move laterally. A slide rail unit 110 is provided in the middle of the base 100. The worktable 400 and the tool magazine assembly 500 are respectively connected to the slide rail unit 110 and can slide along the slide rail unit 100. A collection groove 120 is provided on both sides of the slide rail unit 100. The bottom of the collection groove 120 is inclined, and a collection through hole 130 is opened at the lowest inclined end.

[0036] Specifically, in this embodiment, a slide rail unit 110 is provided in the middle of the base 100. The worktable 400 and the tool magazine 500 are respectively mounted on the slide rail unit 110 and can move along the slide rail unit 110 to facilitate tool changing by the slide block assembly 300 and machining of the workpiece on the worktable 400. Collection grooves 120 are also provided on both sides of the top surface of the base 100, and the two collection grooves 120 are located on both sides of the slide rail unit 110. When the slide block assembly 300 is machining the workpiece on the worktable 400, the waste material and cutting fluid generated will fall directly into the collection grooves 120 on both sides. The waste material and cutting fluid falling into the collection grooves 120 will slide along the inclined bottom surface of the collection grooves 120 and flow from the lowest end of the collection groove. The collection hole 130 slides outward, preventing excessive accumulation of waste material and cutting fluid in the collection tank 120. This avoids affecting the machining center during processing and ensures machining efficiency. Furthermore, if residual waste material in the collection tank 120 fails to slide along the inclined bottom surface, it can be blown out using an air pump, moving it towards the collection hole 130 and facilitating cleaning of the machining center. Water flushing can also be used; the cleaning method is not limited. Cleaning the collection tank 120 does not require stopping the machining center, thus ensuring processing efficiency and utilization, and guaranteeing normal production for the enterprise.

[0037] Please see Figures 4 to 8To enable product processing and tool replacement, the beam assembly 200 in this embodiment includes a fixed bracket 210, a first driving member 220, and a first lead screw 230. The fixed bracket 210 is 'Π' shaped, with both ends mounted on either side of the base 100. The first driving member 220 and the first lead screw 230 are mounted on the fixed bracket 210 and connected to the first lead screw 230. The slide assembly 300 is connected to the first lead screw 230. The first driving member 220 drives the first lead screw 230 to rotate, thereby driving the slide assembly 300 to move laterally. The slide assembly 300 includes a fixed plate 310, a second driving member 320, a second lead screw 330, and an electric spindle 340. The fixed plate 310 is connected to the first lead screw 230. Multiple sets of the second driving member 320 and the second lead screw 330 are provided, corresponding one-to-one, and are respectively mounted on the fixed plate 310. The second drive unit 320 is connected to the second lead screw 330. Each set of second lead screws 330 is connected to an electric spindle 340. The second drive unit 320 drives the second lead screw 330 to rotate, thereby driving the electric spindle 340 to move vertically. The worktable 400 includes a support base 410 and a worktable surface 420. The bottom of the support base 410 is slidably connected to the slide rail unit 110, and the worktable surface 420 is located on top of the support base 410. A tool setter 430 is provided on one side edge facing the tool magazine 500, and the number of tool setters 430 corresponds to the number of electric spindles 340. The tool magazine 500 includes a support platform 510, a tool fixing plate 520 and a tool 530. The bottom of the support platform 510 is connected to the slide rail unit 110, and the tool fixing plate 520 is provided on the top of the support platform 510 and has several tool holes 521. The tool 530 is loaded in the tool holes 521.

[0038] During operation, the product to be processed is placed on the worktable 420, and the drive module drives the support base 410 to move along the slide rail unit 110, thereby moving the product to be processed on the worktable 400 to a set position. Simultaneously, the first drive unit 220 drives the first lead screw 230 to rotate. As the first lead screw 230 rotates, it moves the fixed plate 310, thereby adjusting the lateral position of the sliding assembly 300. After the sliding assembly 300 is adjusted, the second drive unit 320 drives the second lead screw 330 to rotate. The rotation of the second lead screw 330 drives the electric spindle 340 to move vertically, thereby adjusting the position between the tool 530 on the electric spindle 340 and the product to be processed. The spindle 340 drives the tool 530 to process the product to be processed. When the tool 530 needs to be replaced, the drive module drives the worktable 400 away from the crossbeam assembly 200, and another drive module drives the tool magazine 500 to move below the sliding assembly 300. The second drive member 320 of the sliding assembly 300 then drives the second lead screw 330 to rotate, thereby causing the electric spindle 340 to move downward and cooperate with several tools 530 in the tool magazine 500 to replace the tool 530. After the tool 530 is replaced, it can be set by the tool setter 430 on the worktable 420 to measure and compensate for the tool offset value, thereby ensuring the installation accuracy of the tool 530 and eliminating machining errors.

[0039] After the tool 530 is replaced, the drive module will drive the tool magazine 500 away from the sliding group 300 and return it to the set position. In order to ensure accurate reset, a sensor switch 240 is provided on the fixed bracket 210. When the tool magazine 500 is reset, its sensor switch 240 (proximity switch) will sense the tool 530 on the tool magazine 500, and then sense the reset position of the tool magazine 500, thereby ensuring the accuracy of the tool magazine 500 reset.

[0040] In addition, when the electric spindle 340 drives the tool 530 to process the workpiece, the cutting fluid nozzle 350 provided on the side of the electric spindle 340 will spray cutting fluid to ensure the processing effect, while the cutting waste fluid will flow into the collection tank 120, and then flow through the inclined bottom of the collection tank 120 to the collection through hole 130, and then flow outward from the collection through hole 130.

[0041] Meanwhile, in order to prevent the waste material and cutting fluid generated during processing from splashing onto the tool 530 in the tool magazine 500, a baffle 540 is provided on the side of the support platform 510 facing the worktable 400. The baffle 540 can effectively block the waste material and cutting fluid, thereby preventing them from splashing onto the tool 530 and improving the protection of the tool 530.

[0042] Furthermore, in order to ensure the processing effect of the machining center on the product, in this embodiment, an adjustable vibration damping foot 140 is provided at the bottom of the base 100. The adjustable vibration damping foot 140 can effectively reduce the vibration of the machining center when processing the product, thereby improving the processing quality of the product. In addition, the height of the machining center can be adjusted by the adjustable vibration damping foot 140, so that the machining center can adapt to different environments.

[0043] Finally, because the overall weight of the machining center is relatively heavy, in order to reduce the overall weight for easy transportation without affecting the overall strength of the machining center, several weight-reducing holes 600 are respectively opened on the base 100 and the fixed bracket 210. By opening the weight-reducing holes 600, the overall weight of the machining center can be effectively reduced, while ensuring its overall strength.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
