Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a milling machine for sheet metal processing. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, etc., and is commonly used for machining sheet metal. When milling sheet metal, the cutting chips produced are not easily collected.

[0003] Existing technology, such as a utility model of a plate milling machine, authorized publication number CN219837530U, uses a splash-proof assembly. The limiting rod fixed to the baffle on the movable plate is inserted into the limiting groove opened on the baffle on the base plate to form a fixed structure. The four baffles form a closed environment, thereby avoiding the drawback of debris splashing during operation.

[0004] Currently, there is a lack of a dedicated milling machine for sheet metal processing that not only optimizes the chip collection mechanism but also better adapts to the processing needs of sheet metal of different specifications, thereby improving overall work efficiency and processing quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a special milling machine for plate processing. By using adjustable clamping plates, different types of plates can be clamped. After processing, the mounting base 31 can be tilted by moving the sliding clamp, which facilitates the cleaning and collection of cutting chips.

[0006] This utility model achieves its purpose through the following technical solution:

[0007] A special milling machine for sheet metal processing, characterized in that it comprises: a CNC milling machine; a fixture base mounted on the CNC milling machine, the fixture base including a mounting plate, the mounting plate being fixedly connected to the CNC milling machine, the mounting plate being fixedly connected to symmetrical track grooves, the symmetrical track grooves being respectively fixedly connected to positioning plates; a sliding fixture including a mounting shell, the mounting shell having symmetrical straight grooves, a servo motor mounted inside the mounting shell, the output shaft of the servo motor being fixedly connected to a turntable, the turntable being rotatably connected to symmetrical connecting rods, the symmetrical connecting rods being respectively rotatably connected to L-plates, the symmetrical L-plates being... The lower sliders of the plates are respectively set in the corresponding straight grooves, and the symmetrical L-plates are respectively fixedly connected to the clamping plates. The rotation of the turntable drives the L-plates to slide in the straight grooves through the connecting rod, thereby realizing the movement of the clamping plates in opposite directions to meet the fixing requirements of plates of different sizes. During CNC milling, most of the cutting chips generated are concentrated in the area composed of the clamping plates, plates, and positioning plates. The height of the clamping plates and positioning plates is much greater than the thickness of the plates to prevent the cutting chips from leaving this area. The mounting shell bearing connects two sets of symmetrical track wheels, each of which is set in a corresponding track groove. Each set of track wheels slides in conjunction with the corresponding track groove, so that the sliding fixture can slide along the length of the track groove. After two track wheels on one side disengage from the track groove, the mounting shell tilts to facilitate the collection of cutting chips.

[0008] As a further limitation of this technical solution, a guiding assembly is also included. The guiding assembly comprises symmetrical guide plates, each fixedly connected to the central axis of a rotating wheel. The central axis of each rotating wheel is rotatably connected to the mounting housing. Two springs are fixedly connected to their ends, with the two inner springs rotatably connected to the mounting housing and the two outer springs rotatably connected to the edges of their respective rotating wheels. The springs have two natural states: in one state, the guide plates and clamping plates are parallel; in the other state, the guide plates are tilted, and the two guide plates converge, which can more effectively guide the cutting chips into the collecting device, further improving the chip collection efficiency.

[0009] As a further limitation of this technical solution, the mounting plate is fixedly connected to symmetrical rack seats, and each of the symmetrical rack seats is fixedly connected to a rack. The central shafts of the symmetrical rotating wheels are respectively fixedly connected to gears, and each of the symmetrical gears is matched with a corresponding rack. When the mounting shell is pulled outward, the meshing action of the gears and racks causes the rotating wheels to rotate, thereby causing the guide plate to swing.

[0010] As a further limitation of this technical solution, the mounting shell is fixedly connected to at least one anti-collision spring and a guide tube. The anti-collision spring is disposed inside the guide tube, and a ball joint rod is disposed inside the guide tube. The anti-collision spring is fixedly connected to the ball joint rod. When the mounting shell is pushed or pulled by an external force, especially when pulled outward, the mounting shell is slowly lowered when the track wheel contacts the limiting plate. The ball joint rod contacts the mounting plate and moves along the guide tube, compressing the anti-collision spring at the same time.

[0011] As a further limitation of this technical solution, guide rods are respectively provided in the symmetrical straight grooves, and the symmetrical guide rods are respectively fixedly connected to the mounting shell. The symmetrical guide rods pass through the lower sliders of the corresponding L-plates, thereby enhancing the stability of the L-plate movement.

[0012] As a further limitation of this technical solution, limit plates are installed in the symmetrical track grooves to limit the track wheels and prevent the sliding clamp from disengaging from the clamp seat.

[0013] As a further limitation of this technical solution, the mounting shell is fixedly connected to symmetrical mounting seats, and the positioning plate is provided with symmetrical threaded holes. Symmetrical bolts pass through the corresponding mounting seats, and the symmetrical bolts are threaded into the corresponding threaded holes. In this way, the mounting shell can be firmly installed on the positioning plate, ensuring a stable connection between the sliding clamp and the clamp seat.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are:

[0015] Compared with the prior art, the advantages and positive effects of this utility model are:

[0016] (1) This utility model uses track wheels to facilitate the movement of the sliding clamp. When it is tilted, the cutting chips can slide down and be collected. The mounting shell is firmly connected to the positioning plate through the mounting base and bolts, which simplifies the installation steps, improves the installation efficiency, and facilitates the later maintenance and replacement.

[0017] (2) This utility model uses a clamping plate to clamp different types of plates, which facilitates the processing of CNC milling machines.

[0018] (3) By adopting a swingable guide plate, the two guide plates are in a converging shape, which can more effectively guide the cutting chips into the collection device.

[0019] (4) This utility model uses a gear rack and pinion mechanism and an anti-collision spring to achieve automatic opening and closing of the protective plate, which is practical and convenient. Attached Figure Description

[0031] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0032] Example 1: This utility model includes: a CNC milling machine 1; a fixture base 2, mounted on the CNC milling machine 1, the fixture base 2 including a mounting plate 21, the mounting plate 21 being fixedly connected to the CNC milling machine 1, the mounting plate 21 being fixedly connected to symmetrical track grooves 22, the symmetrical track grooves 22 being respectively fixedly connected to positioning plates 23; a sliding fixture 3 including a mounting shell 33, the mounting shell 33 having symmetrical straight grooves 34, the mounting shell 33 housing a servo motor 310, the output shaft of the servo motor 310 being fixedly connected to a turntable 39, the turntable 39 being rotatably connected to symmetrical connecting rods 38, the symmetrical connecting rods 38 being respectively rotatably connected to L-plates 37, the symmetrical L-plates... The lower sliders of the L-plates 37 are respectively set in the corresponding straight grooves 34, and the symmetrical L-plates 37 are respectively fixedly connected to the clamping plates 36. The rotation of the turntable 39 drives the L-plates 37 to slide in the straight grooves 34 through the connecting rod 38, thereby realizing the opposite or opposite movement of the clamping plates 36 to adapt to the fixing requirements of plates of different sizes. When the CNC milling machine 1 is processed, most of the cutting chips generated are concentrated in the area composed of the clamping plates 36, the plate and the positioning plate 23. The height of the clamping plates 36 and the positioning plate 23 is much greater than the thickness of the plate to prevent the cutting chips from leaving this area. The mounting shell 33 is connected to two sets of symmetrical track wheels 311 by bearings. Each track wheel 311 is respectively set in the corresponding track groove 22. Each set of track wheels 311 slides with the corresponding track groove 22, so that the sliding clamp 3 can slide along the length direction of the track groove 22. After the two track wheels 311 on one side are disengaged from the track groove 22, the mounting shell 33 tilts to facilitate the collection of cutting chips.

[0033] A protective cover is provided on the outside of the CNC milling machine 1 (not shown in the figure).

[0034] Guide rods 35 are respectively provided in the symmetrical straight grooves 34, and the symmetrical guide rods 35 are respectively fixedly connected to the mounting shell 33. The symmetrical guide rods 35 pass through the lower slider of the corresponding L plate 37, thereby enhancing the stability of the movement of the L plate 37.

[0035] Limiting plates 25 are installed in the symmetrical track grooves 22 to limit the track wheels 311 and prevent the sliding clamps 3 from disengaging from the clamp seats 2.

[0036] The mounting shell 33 is fixedly connected to symmetrical mounting bases 31. The positioning plate 23 is provided with symmetrical threaded holes 24. Symmetrical bolts 32 pass through the corresponding mounting bases 31 and are threaded into the corresponding threaded holes 24. In this way, the mounting shell 33 can be firmly installed on the positioning plate 23, ensuring a stable connection between the sliding clamp 3 and the clamp base 2.

[0037] The workflow of this embodiment is as follows:

[0038] Place the plate onto the mounting housing 33, with one end contacting the positioning plate 21. Control the servo motor 310 to rotate. The servo motor 310 drives the turntable 310 to rotate. The turntable 310 drives the connecting rod 38 to swing. The connecting rod 38 drives the L plate 37 to move along the guide rod 35 in the straight groove 34. The L plate 37 drives the clamping plate 36 to move, so that the clamping plate 36 clamps the plate.

[0039] Operate the CNC milling machine 1 to process the sheet metal. After processing, place a collection device on one side of the CNC milling machine 1, unscrew the bolt 32, move the mounting shell 32 to move the sliding fixture 3, so that the two track wheels 311 on one side move out of the track groove 22 until the two track wheels 311 on the other side contact the limiting plate 25, slowly lower the mounting seat 31 to tilt it, so that the cutting chips fall into the collection device.

[0040] Example 2: This example further elaborates on Example 1 and includes a guide assembly 4. The guide assembly 4 includes symmetrical guide plates 41, each fixedly connected to the central axis of a rotating wheel 48. The central axis of the rotating wheel 48 is rotatably connected to the mounting housing 33. Two ends of symmetrical springs 42 are fixedly connected to spring posts 43. The two inner spring posts 43 are rotatably connected to the mounting housing 33, and the two outer spring posts 43 are rotatably connected to the edges of the corresponding rotating wheels 48. The springs 42 have two natural states: in one state, the guide plates 41 and the clamping plate 36 are parallel; in the other state, the guide plates 41 are tilted, and the two guide plates 41 converge, which can more effectively guide the cutting chips into the collecting device, further improving the chip collection efficiency.

[0041] The mounting plate 21 is fixedly connected to symmetrical rack seats 49, and the symmetrical rack seats 49 are respectively fixedly connected to racks 410. The central shafts of the symmetrical rotating wheels 48 are respectively fixedly connected to gears 47, and the symmetrical gears 47 are respectively matched with the corresponding racks 410. When the mounting shell 33 is pulled outward, the rotating wheels 48 are rotated through the meshing action of the gears 47 and the racks 410, thereby causing the guide plate 41 to swing.

[0042] The workflow of this embodiment is as follows:

[0043] When the mounting housing 32 is moved, gear 47 meshes with rack 410, gear 47 rotates, gear 47 drives rotating wheel 48 to rotate, rotating wheel 48 drives guide plate 41 to swing, rotating wheel 48 drives outer spring column 43 to swing, outer spring column 43 drives anti-collision spring 45 to swing, anti-collision spring 45 drives inner spring column 43 to rotate. When the mounting housing 32 is moved further, gear 47 disengages from rack 410, thus maintaining the position of guide plate 41.

[0044] Example 3: This example further elaborates on Example 2. The mounting housing 33 is fixedly connected to at least one anti-collision spring 45 and a guide tube 44. The anti-collision spring 45 is disposed within the guide tube 44, and a ball joint rod 46 is disposed within the guide tube 44. The anti-collision spring 45 is fixedly connected to the ball joint rod 46. When the mounting housing 33 is pushed or pulled by an external force, especially when pulled outwards, the mounting housing 33 is slowly lowered when the track wheel 311 contacts the limiting plate 25. The ball joint rod 46 contacts the mounting plate 21 and moves along the guide tube 44, simultaneously compressing the anti-collision spring 45, thus maintaining the tilt of the mounting housing 33.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
