Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, and in particular to a woodworking CNC milling machine. Background Technology

[0002] The woodworking milling machine mainly includes a worktable, a movable milling mechanism mounted on the worktable, and a drive mechanism. Its working process is roughly as follows: First, the board to be processed is manually moved to the predetermined position on the worktable of the woodworking milling machine. Then, the switch is turned on, and the milling mechanism is automatically driven to process the board on the worktable through CNC programming and drive mechanism.

[0003] Through use, it was found that existing milling machines have the following shortcomings:

[0004] 1) Most milling machines use a single spindle structure. If multiple identical parts are to be processed, they can only be processed one by one, and multiple tool settings are required. Problems are prone to occur during the tool setting process, which is time-consuming and cannot improve work efficiency.

[0005] 2) If a single-spindle milling machine like the one described above needs to be machined at multiple positions on a part at the same time, the spindle needs to switch between multiple machining positions to complete the machining. This machining method is time-consuming and is also a reason for low work efficiency.

[0006] 3) Before and after milling, materials need to be picked up and put down manually. The manual placement of the plate on the worktable and the loading and unloading process will take a certain amount of time to wait for processing, so the processing speed will be affected by manual operation. Utility Model Content

[0007] Therefore, the technical problem to be solved by this utility model is to overcome the problem of low work efficiency caused by the single spindle and single worktable mode of the existing milling machine.

[0008] To solve the above-mentioned technical problems, this utility model provides a woodworking CNC milling machine, comprising: a bed on which at least one worktable is provided; a machine frame; a horizontal moving device mounted on the crossbeam of the machine frame; a vertical moving device mounted on the horizontal moving device; and a plurality of machining spindles mounted on the vertical moving device. The horizontal moving device and the vertical moving device constitute a dual-axis moving mechanism for driving the plurality of machining spindles to move.

[0009] In one embodiment of this utility model, the milling machine further includes several tool magazines, which are arranged in a one-to-one correspondence with several machining spindles. The tool magazines are mounted on the machining spindles and are used for tool changing on the corresponding machining spindles.

[0010] In one embodiment of this utility model, the number of worktables is set to two. When the milling machine is processing small workpieces, the two worktables switch between working and loading / unloading in turn. When the milling machine is processing large workpieces, the two worktables are synchronized and linked to place the large workpieces and load / unload them.

[0011] In one embodiment of the present invention, the horizontal moving device includes a horizontal drive motor, a drive wheel, a rack, and a horizontal moving slide plate. The rack is mounted on the crossbeam of the machine tool frame, the horizontal drive motor is mounted on the horizontal moving slide plate, the drive wheel is connected to the output end of the horizontal drive motor, and the drive wheel meshes with the rack.

[0012] In one embodiment of this utility model, the vertical moving device includes a vertical drive motor, a vertical drive screw, and a vertical moving plate. The vertical drive motor and the vertical drive screw are both mounted on a horizontal moving slide plate. The output end of the vertical drive motor is connected to the vertical drive screw. The vertical moving plate and the vertical drive screw are connected by a nut pair. Several machining spindles are arranged in parallel on the vertical moving plate.

[0013] In one embodiment of this utility model, each machining spindle is provided with a protective cover assembly, which is used to cover the machining head of the machining spindle.

[0014] In one embodiment of the present invention, the protective cover assembly includes at least one drive cylinder and a protective cover. The drive cylinder is mounted on the tool post of the machining spindle. The protective cover is connected to the output end of the drive cylinder. The drive cylinder drives the protective cover to cover the machining head of the machining spindle.

[0015] In one embodiment of this utility model, the tool magazine includes a tool magazine frame, a tool magazine drive cylinder, a tool magazine horizontal slide plate, a tool magazine vertical drive cylinder, a tool magazine support frame, and a tool magazine body. The tool magazine frame is connected to a vertical moving device. The tool magazine drive cylinder is mounted on the tool magazine frame, and its output end is connected to the tool magazine horizontal slide plate. The tool magazine vertical drive cylinder is mounted on the tool magazine horizontal slide plate, and its output end is connected to the tool magazine support frame. The tool magazine body is mounted on the tool magazine support frame.

[0016] In one embodiment of this utility model, the tool magazine body includes a tool disc, a tool disc drive motor, and a plurality of tool grippers. The tool disc drive motor is mounted on a tool magazine support frame. The tool disc and the output end of the tool disc drive motor are connected. The plurality of tool grippers are arranged in a circular array on the tool disc, and tools are mounted on the tool grippers.

[0017] In one embodiment of the present invention, the worktable includes a linear module and a machining table. The linear module is mounted on the bed, the machining table is connected to the linear module, and the machining table and the bed are slidably connected.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0019] The woodworking CNC milling machine described in this utility model is equipped with two worktables, four spindles, and four tool magazines.

[0020] 1) The four spindles can operate independently or synchronously. Through command control, they can automatically grip, change tools, operate automatically, and process workpieces according to different process requirements. Furthermore, the spacing between the four spindles can be freely adjusted within their travel range, allowing for selection of the required spindle spacing based on the size of the workpiece.

[0021] 2) The two worktables work together; when one is in operation, the other can be used for loading and unloading. The two worktables work alternately, avoiding downtime during loading and unloading, thus allowing the spindle to work continuously for a long time. The synchronous operation of the four spindles increases the processing efficiency to four times the original. Adjusting the spindle spacing can reduce the generation of scrap, achieving the effect of saving raw materials. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0034] Reference Figure 1 , 2 As shown, the woodworking CNC milling machine of this utility model includes: a bed 1, on which at least one worktable 2 is provided; a machine frame 3; a horizontal moving device 4, which is mounted on the crossbeam of the machine frame 3; a vertical moving device 5, which is disposed on the horizontal moving device 4; and a plurality of machining spindles 6, which are mounted on the vertical moving device 5.

The machine frame 3 is gantry type, the bed 1 is located between two columns of the machine frame 3, and the worktable 2 is located below the crossbeam of the machine frame 3.

[0035] Reference Figure 3 ,4 As shown, the horizontal moving device 4 includes a horizontal drive motor 41, a drive wheel 42, a rack 43, and a horizontal moving slide plate 44. The rack 43 is mounted on the crossbeam of the machine tool frame 3, the horizontal drive motor 41 is mounted on the horizontal moving slide plate 44, the drive wheel 42 is connected to the output end of the horizontal drive motor 41, and the drive wheel 42 meshes with the rack 43. The vertical moving device 5 is entirely mounted on the horizontal moving slide plate 44. Two parallel horizontal linear guides 31 are provided on the side of the crossbeam of the machine tool frame 3. The horizontal linear guides 31 and the rack 43 are arranged in parallel. A horizontal slider 441 is connected to the horizontal moving slide plate 44. The horizontal slider 441 is set on the horizontal linear guides 31. When the output end of the horizontal drive motor 41 drives the drive wheel 42 to rotate, the drive wheel 42 moves along the rack 43. At this time, the horizontal slider 441 slides along the horizontal linear guides 31, thereby driving several machining spindles 6 set on the vertical moving device 5 to move in the horizontal direction. The machining spindles 6 are adjusted to switch between the two worktables 2, and the relative position between the machining spindles 6 and the worktables 2 is adjusted, thereby realizing the machining of the machining spindles 6.

[0036] Reference Figure 5 As shown, the vertical moving device 5 includes a vertical drive motor 51, a vertical drive screw 52, ​​and a vertical moving plate 53. Both the vertical drive motor 51 and the vertical drive screw 52 are mounted on a horizontal moving slide plate 44. The output end of the vertical drive motor 51 is connected to the vertical drive screw 52. The vertical moving plate 53 and the vertical drive screw 52 are connected by a nut pair. Several machining spindles 6 are arranged in parallel on the vertical moving plate 53. Several vertical guide rails 442 are provided on the horizontal moving slide plate 44, and these guide rails 442 are arranged in parallel. A vertical slider 531 is provided on the vertical moving plate 53. The vertical slider 531 is disposed on the vertical guide rails 442, and during the rotation of the vertical drive motor 51 driving the vertical drive screw 52, ​​the vertical slider 531 slides up and down along the vertical guide rails 442. The horizontal moving slide plate 44 is a rectangular plate. Both ends of the horizontal moving slide plate 44 are equipped with lifting auxiliary cylinders 443. The piston rod of the lifting auxiliary cylinder 443 is connected to the vertical moving plate 53. Since there are four processing spindles 6, when the vertical drive motor 51 drives the vertical moving plate 53 to rise and fall, the lifting auxiliary cylinders 443 on both sides can provide auxiliary power to achieve stable rising and falling of the vertical moving plate 53.

[0037] The vertical moving plate 53 is provided with a plurality of spindle drive cylinders 532, and the plurality of spindle drive cylinders 532 and the plurality of machining spindles 6 are arranged in a one-to-one correspondence. The spindle drive cylinders 532 are used to adjust the corresponding machining spindles 6 in the vertical position.

[0038] Reference Figure 6As shown, each machining spindle 6 is equipped with a protective cover assembly 8, which is used to cover the machining head of the machining spindle 6.

The drive cylinder 81 is mounted on the tool holder of the machining spindle 6, and the protective cover 82 is connected to the output end of the drive cylinder 81. The drive cylinder 81 drives the protective cover 82 to cover the machining head of the machining spindle 6. Preferably, the number of drive cylinders 81 is set to three, with the three drive cylinders 81 located at the three vertices of a triangle. The machining spindle 6 is located within the area of ​​the triangle formed by the three drive cylinders 81. By driving the protective cover 82 to rise and fall with the three drive cylinders 81, the machining spindle 6 is shielded, ensuring safety during machining. Furthermore, the protective cover 82 is equipped with a dust collection port 821, which is connected to a dust removal device to collect debris generated during machining.

[0039] Reference Figure 9 As shown, the number of worktables 2 is set to two, and the two worktables 2 alternately switch between working and loading / unloading. With two worktables 2, when one worktable 2 is in working state, the other worktable 2 can perform loading / unloading work, thus saving the time required for loading / unloading on a single worktable. Specifically, when the milling machine processes small workpieces, the two worktables 2 alternately switch between working and loading / unloading, and the cross-sectional area of ​​the small workpiece is much smaller than the cross-sectional area of ​​the worktable 2; when the milling machine processes large workpieces, the two worktables 2 work synchronously and in conjunction for placing and loading / unloading the large workpiece, and the cross-sectional area of ​​the large workpiece is larger than the cross-sectional area of ​​the worktable 2. The worktable 2 includes a linear module 21 and a machining table 22. The linear module 21 is mounted on the bed 1, and the machining table 22 is connected to the linear module 21 and slidably connected to the bed 1. The linear module 21 can be selected from cylinders, hydraulic cylinders, or linear motors according to specific needs, or it can be a combination of a servo motor and a lead screw, connected to the machining table 22 and the lead screw via a nut pair, driving the machining table 22 to move linearly. The bed 1 is equipped with a linear guide rail parallel to the moving direction of the linear module 21. The bed 1 is also equipped with a slider. When the linear module 21 drives the machining table 22 to move linearly, the slider slides along the linear guide rail. The two worktables 2 are arranged side by side. The linear module 21 drives the machining table 22 to be located below the machining spindle 6 or at the loading / unloading position. Example 2

[0040] Reference Figure 6 , 7As shown, the milling machine also includes several tool magazines 7, which are arranged one-to-one with several machining spindles 6. The tool magazines 7 are mounted on the machining spindles 6 and are used for tool changing on their respective machining spindles 6. Each machining spindle 6 corresponds to one tool magazine 7, so for this type of milling machine with multiple machining spindles 6, multiple tool magazines 7 can meet the flexible tool changing requirements.

[0041] Reference Figure 8 As shown, the tool magazine 7 includes a tool magazine frame 71, a tool magazine drive cylinder 72, a tool magazine horizontal slide plate 73, a tool magazine vertical drive cylinder 74, a tool magazine support frame 75, and a tool magazine body 76. The tool magazine frame 71 is connected to the vertical moving device 5. The tool magazine drive cylinder 72 is mounted on the tool magazine frame 71, and its output end is connected to the tool magazine horizontal slide plate 73. The tool magazine vertical drive cylinder 74 is mounted on the tool magazine horizontal slide plate 73, and its output end is connected to the tool magazine support frame 75. The tool magazine body 76 is mounted on the tool magazine support frame 75. The tool magazine holder 71 has a tool magazine guide rail 711 on its side wall, and a tool magazine guide slider 731 is connected to the tool magazine body 76. The tool magazine guide rail 711 is arranged along the extension and retraction direction of the piston rod of the tool magazine drive cylinder 72. The tool magazine guide slider 731 is mounted on the tool magazine guide rail 711. When the tool magazine drive cylinder 72 drives the tool magazine body 76 to move closer to or away from the machining spindle 6, the tool magazine guide slider 731 slides along the tool magazine guide rail 711. The tool magazine horizontal slide plate 73 has a tool magazine guide slider 732, and the tool magazine support frame 75 has a tool magazine guide rail 751. The tool magazine guide slider 732 and the tool magazine guide rail 751 are slidably connected. When the tool magazine vertical drive cylinder 74 drives the tool magazine support frame 75 to move up and down in the vertical direction, the tool magazine guide rail 751 slides within the tool magazine guide slider 732. The piston rod of the tool magazine drive cylinder 72 extends and retracts in the horizontal direction, and the piston rod of the tool magazine vertical drive cylinder 74 extends and retracts in the vertical direction. The tool magazine drive cylinder 72 and the tool magazine vertical drive cylinder 74 cooperate in both the horizontal and vertical directions to drive the tool magazine body 76 to move to the tool changing position close to the machining spindle 6 to realize tool changing.

[0042] Reference Figure 8As shown, the tool magazine body 76 includes a tool disc 733, a tool disc drive motor 734, and a plurality of tool grippers 735. The tool disc drive motor 734 is mounted on the tool magazine support frame 75. The tool disc 733 is connected to the output end of the tool disc drive motor 734. The plurality of tool grippers 735 are arranged in a circular array on the tool disc 733, and tools are mounted on the tool grippers 735. Each tool gripper 735 includes two symmetrically arranged gripper bodies 736 and a spring 737. One end of each gripper body 736 is connected to the tool disc 733 via a rotating shaft, and the other end of each gripper body 736 extends out of the tool disc 733. The spring 737 is arranged between the ends of the two gripper bodies 736 located within the tool disc 733. The ends of the two gripper bodies 736 extending out of the tool disc 733 are used to grip the tools, and the ends of the two gripper bodies 736 extending out of the tool disc 733 are arranged in a "C" shape. Spring 737 provides elastic force between the two gripper bodies 736 to hold the tool. Several tool grippers 735 leave a spare position. When a tool change is needed, the tool magazine drive cylinder 72 and the tool magazine vertical drive cylinder 74 work together in both horizontal and vertical directions to move the tool magazine body 76 close to the machining spindle 6. The tool on the machining spindle 6 is inserted between the two gripper bodies 736. The tool turret drive motor 734 drives the tool turret 733 to rotate, moving the tool to be used on the tool turret 733 to below the machining spindle 6, thus realizing the tool change.
