Description

Technical Field

[0001] The present invention relates to the technical field of CNC milling machines, and in particular to a CNC milling machine for intelligent material handling and positioning. Background Art

[0002] In the field of modern machining, CNC milling machines, with their high precision and high efficiency, have become a core piece of industrial production equipment. Traditional CNC milling machines rely on manual material handling, placing materials on the workbench and then manually adjusting the material position to meet processing requirements. This manual operation is not only labor-intensive but also prone to operator fatigue after long hours of work, leading to deviations in material placement, which in turn affects machining accuracy and production efficiency.

[0003] At present, some CNC milling machines have introduced some simple mechanical auxiliary devices to assist in material handling, such as using a fixed conveyor belt to transport materials to the vicinity of the workbench, and then manually performing the final positioning and adjustment. Although these mechanical devices have reduced the manpower burden to a certain extent, their structure is relatively simple and their functions are limited.

[0004] In actual production scenarios, when it is necessary to process materials of different specifications and shapes, the disadvantages of the material handling and positioning methods of existing CNC milling machines are highlighted. For example, when processing large parts, manual handling is not only laborious, but also difficult to ensure the precise position of the material on the workbench, which easily leads to processing size errors; when processing small batches and a wide variety of materials, frequent material replacement requires manual re-positioning and adjustment, which greatly reduces production efficiency. It is difficult to automatically adjust the position and posture according to the actual situation of the material. The various mechanical structures are independent of each other and fail to form an organic whole, making it difficult to meet the needs of modern manufacturing for efficient, precise, and intelligent processing. Therefore, the present invention provides a CNC milling machine with intelligent material handling and positioning to address the shortcomings of the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see the attached Figure 1 -Attached Figure 10 An embodiment of the present invention provides a CNC milling machine for intelligent material handling and positioning, including a mounting base 1, a machine tool body 2 is mounted on the side wall of the mounting base 1, a workbench 3 is fixedly connected to the outer side of the mounting base 1 and is located directly below the machine tool body 2, a lifting mechanism 4 is provided on the outer side of the mounting base 1, a positioning mechanism 5 is provided on the top of the lifting mechanism 4, and a pushing mechanism 6 is provided on the outer side of the positioning mechanism 5.

[0022] The lifting mechanism 4 includes two assembly bases 401, a cylindrical gear 1 406, and a shift lever 415. The top of the assembly base 401 is rotatably connected to a connecting frame 1 402, one end of which is rotatably connected to two connecting frames 2 403. A disc 407 is fixedly connected to the top of the cylindrical gear 1 406. A threaded post 408 is fixedly connected to the top of the disc 407. The outer side of the threaded post 408 is threadedly connected to a threaded sleeve 405. The top of the threaded sleeve 405 is fixedly connected to the support platform 404. One end of the connecting frame 2 403 is rotatably connected to the bottom of the support platform 404. An L-shaped plate 409 is fixedly connected to the outer side of the mounting base 1. A motor 1 410 is mounted on the outer side of the L-shaped plate 409. The output end of the motor 1 410 is fixedly connected to a cylindrical gear 2 411, which meshes with the cylindrical gear 1 406. The top of cylindrical gear 406 is rotatably connected to a rotating ring 413, and a plurality of holes 414 are provided inside the rotating ring 413. A plurality of slots 412 are provided on the outside of the disc 407. The outside of the shifting rod 415 is slidably connected to the inside of the hole 414 and one end of the lever is engaged in the inside of the slot 412.

[0023] Two assembly bases 401 stably support connecting frame 1 402, ensuring its rotational stability. Motor 1 410 drives cylindrical gear 2 411 to rotate, which in turn drives cylindrical gear 1 406 through meshing, causing disc 407 to rotate and driving threaded column 408 to rotate. Threaded column 408 and threaded sleeve 405 engage through threads, causing threaded sleeve 405 to move axially in a straight line, thereby driving support platform 404 up and down to achieve material height adjustment. When motor 1 410 is unusable or manual fine-tuning is required, one end of lever 415 can be inserted into jack 414 and slot 412. By pushing lever 415, disc 407 rotates, achieving the same function and providing multi-mode operational adaptability.

[0024] The positioning mechanism 5 includes a clamping assembly and a lifting assembly. The lifting assembly includes a lifting frame 510, the bottom of the lifting frame 510 is fixedly connected to the top of the support platform 404, and a conveyor belt 511 is installed inside the lifting frame 510. The clamping assembly includes two assembly frames 501, which are fixedly connected to the outside of the lifting frame 510. Motor 2 502 is installed at the bottom of the assembly frame 501, and the output end of motor 2 502 is fixedly connected to a rotating piece 503. The outside of the rotating piece 503 is rotatably connected to two connecting pieces 504. Two strip holes 506 are provided inside the assembly frame 501, and a sliding block 505 is slidably connected to the inner side of the strip hole 506. The top of the sliding block 505 is rotatably connected to one end of the connecting piece 504. The outer side of the connecting piece 504 is fixedly connected to a mounting column 507, and the bottom of the mounting column 507 is slidably connected to the top of the assembly frame 501. The inner side of the mounting column 507 is rotatably connected to a rotating roller 508, and a plurality of anti-slip strips 509 are provided on the periphery of the rotating roller 508.

[0025] In the lifting assembly, the lifting frame 510 serves as the support base. Once the conveyor belt 511 is activated, friction drives the material toward the machine tool body 2. In the clamping assembly, motor 2 502 drives the rotating plate 503, which in turn swings the connecting plate 504. This pulls the sliding block 505 along the strip-shaped hole 506, causing the mounting post 507 to move the rotating roller 508. Anti-slip strips 509 on the outer periphery of the rotating roller 508 contact both sides of the material, clamping and positioning it, preventing material displacement and ensuring processing stability.

[0026] Pushing mechanism 6 includes a guide plate 601, one end of which is fixedly connected to the outside of assembly frame 501, away from machine tool body 2. A limit block 602 is fixedly connected to one end of guide plate 601. A movable plate 603 is slidably connected to the outside of guide plate 601, and a forked push plate 604 is fixedly connected to the top of movable plate 603. Motor 3 605 is installed inside assembly frame 501, adjacent to guide plate 601. The output end of motor 3 605 is fixedly connected to a reeling rod 606. A pull rope 607 is fixedly connected to the outside of reeling rod 606, and one end of pull rope 607 is fixedly connected to the outside of movable plate 603.

[0027] Guide plate 601 guides the movable plate 603, while stopper 602 prevents it from dislodging from guide plate 601. Motor 3 605 drives reel rod 606 to rotate, reeling or unreeling pull cord 607, thereby pulling movable plate 603 along guide plate 601. The movable plate 603 drives the forked push plate 604 to push the material, which, in conjunction with the rotation of conveyor belt 511, enables rapid and stable material transfer to the machine tool body 2, significantly reducing manual labor intensity.

[0028] Specifically, first, place the material to be processed on the conveyor belt 511 of the lifting assembly. At this time, the material height can be adjusted in two modes. The first is the electric mode. Start the motor 1 410, and its output end drives the cylindrical gear 2 411 to rotate. Since the cylindrical gear 2 411 is engaged with the cylindrical gear 1 406, the cylindrical gear 1 406 rotates accordingly, and the disc 407 fixed on the top of the cylindrical gear 1 406 also rotates synchronously, thereby driving the threaded column 408 to rotate. The threaded column 408 and the threaded sleeve 405 are matched through threads. When the threaded column 408 rotates, the threaded sleeve 405 is restricted by the connecting frame 2 403 and cannot rotate. It can only make a linear motion along the axial direction of the threaded column 408, driving the support platform 404 to rise, thereby raising the material position. The second mode is manual mode. When motor 1 410 cannot be used or needs fine-tuning, one end of the lever 415 is passed through one of the holes 414 inside the rotating ring 413 and then inserted into the slot 412 outside the disc 407. The lever 415 is pushed, and the sliding relationship between the lever 415 and the hole 414 and the engagement relationship with the slot 412 drives the disc 407 to rotate, thereby rotating the threaded column 408, which can also lift the material to a specified height. After the material is lifted into position, motor 2 502 is started, and its output drives the rotating plate 503 to rotate. As the rotating plate 503 rotates, it causes the two connecting plates 504, which are rotatably connected to it, to swing. Because one end of the connecting plate 504 is rotatably connected to the sliding block 505, and the sliding block 505 slides within the strip-shaped hole 506 inside the assembly frame 501, the swinging of the connecting plate 504 pulls the sliding block 505 in a linear motion along the strip-shaped hole 506, thereby driving the mounting post 507 to move, bringing the rotating roller 508 inside the mounting post 507 closer to the material. As the rotating roller 508 moves, the multiple anti-slip strips 509 on its outer periphery come into close contact with both sides of the material, clamping and positioning the material, ensuring that the material remains neat and stable during subsequent handling and processing, without displacement or shaking. After the material is positioned, motor three 605 is started, and its output end drives the reeling rod 606 to rotate, reeling in the pull rope 607. Because one end of the pull rope 607 is fixedly connected to the outside of the movable plate 603, when the pull rope 607 is reeled in, it pulls the movable plate 603 along the outside of the guide plate 601 toward the machine tool body 2. The forked push plate 604 on top of the movable plate 603 moves accordingly, pushing the material placed on the lifting assembly. At the same time, the conveyor belt 511 is started. Under the dual action of the forked push plate 604 and the conveyor belt 511, the material can be quickly and stably moved from the lifting assembly to the machine tool body 2. The entire process does not require extensive manual intervention, effectively saving labor and improving processing efficiency.

[0029] Working principle: First, the material to be processed can be placed on the lifting component, and then the motor 1 410 is started to drive the cylindrical gear 2 411 to rotate, and then the cylindrical gear 1 406 is rotated, so that the disc 407 drives the threaded column 408 to rotate, and then the threaded sleeve 405 drives the support platform 404 to move up, so as to raise the position of the material. Alternatively, one end of the lever 415 can be passed through one of the holes 414, and then inserted into the slot 412 to push the lever 415 to make the disc 407 drive the threaded column 408 to rotate. Two modes can be selected to lift the material to a specified height. degrees; in addition, starting motor 2 502 drives the rotating piece 503 to rotate, which in turn drives the two connecting pieces 504 to rotate, thereby pulling the sliding block 505 to drive the mounting column 507 to move, so that the rotating roller 508 clamps and positions the two sides of the material to keep the material neatly arranged, and then starting motor 3 605 drives the winding rod 606 to rotate, which can allow the pull rope 607 to wind up and pull the movable plate 603 to move, so that the fork-shaped push plate 604 can push the material to move, and starting the conveyor belt 511 can allow the material on its top to move to the machine tool body 2, saving a lot of manual labor.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
