Description

Technical Field

[0001] This utility model relates to the technical field of steel processing equipment, and in particular to a mobile small steel milling machine. Background Technology

[0002] Steel milling machines are indispensable key equipment in steel structure manufacturing, bridge engineering, and machining. Their main function is to mill, bevel, or chamfer the edges of materials such as steel plates and profiles to facilitate subsequent welding or assembly processes.

[0003] As modern construction and production models evolve towards greater flexibility and efficiency, large, stationary milling machines can no longer meet the needs of all application scenarios, especially in space-constrained on-site construction or multi-station, small-batch production environments. Therefore, miniaturized, mobile steel milling machines have emerged, gaining widespread application due to their compact structure and ease of relocation.

[0004] However, in the existing technology, such portable small steel milling machines, in pursuit of structural simplification and cost control, typically have significant shortcomings in two key aspects:

[0005] Firstly, in terms of workpiece clamping, manual screws, pressure plates, or simple pneumatic clamps are commonly used for positioning and locking. The drawback of this method is that the operation is cumbersome, relies heavily on the operator's experience and physical strength, and makes it difficult to guarantee the stability and consistency of the clamping force. When the clamping force is too large, it can easily cause deformation damage to thin-walled or high-precision steel; while when the clamping force is insufficient, the steel is prone to displacement or vibration under the milling force, seriously affecting machining accuracy and surface quality. Furthermore, each time different specifications of steel are changed, time-consuming manual readjustment is required, resulting in low processing efficiency and low versatility and automation.

[0006] Secondly, regarding the handling of milling waste, the milling process generates a large amount of high-temperature, sharp metal chips. Simpler models often neglect effective chip removal design, leading to a large accumulation of chips in the machining area. This not only obstructs the operator's view and operational safety but also gets caught between the milling cutter and the workpiece, scratching the machined surface and reducing machining quality. While some slightly improved equipment is equipped with negative pressure dust collection devices, their simple chip suction port design makes them prone to clogging when faced with irregular or adhered steel chips, causing a sudden drop in suction power and interruption of chip removal. Operators must frequently stop the machine for manual cleaning, severely disrupting the continuity of operations and significantly reducing overall work efficiency.

[0007] Therefore, this utility model proposes a mobile small steel milling machine to overcome the shortcomings of the prior art. Utility Model Content

[0008] To overcome the above shortcomings, this utility model provides a mobile small steel milling machine, which aims to improve the problem that some existing milling machines are difficult to achieve adaptive clamping and positioning.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A portable small steel milling machine includes a base, a support column fixedly connected to the outside of the base, a main spindle motor rotatably connected to the outside of the support column, a follower plate fixedly connected to the outside of the main spindle motor, a milling table fixedly connected to the outside of the follower plate, an adjustment mechanism provided outside the support column, and a chip removal mechanism provided outside the base.

[0011] The adjustment mechanism includes a guide groove. The milling table has a guide groove on its outside. A clamping plate is slidably connected to the outside of the milling table. The clamping plate is slidably connected in the guide groove. A follower block is slidably connected inside the milling table. Multiple connecting plates are rotatably connected to the top of the follower block. Multiple connecting plates are rotatably connected to the bottom of the follower block. A support block is fixedly connected to the outside of the support column. A drive assembly is fixedly connected to the outside of the support block.

[0012] As a further description of the above technical solution:

[0013] The drive assembly includes a hydraulic cylinder, which is fixedly connected to the support column. The drive end of the hydraulic cylinder is fixedly connected to a transmission rod, which is fixedly connected to the follower block. The milling table has multiple opening slots inside, and multiple fixed rods are rotatably connected inside the opening slots.

[0014] As a further description of the above technical solution:

[0015] The milling table is rotatably connected to a positioning roller, and the milling table is rotatably connected to a milling cutter.

[0016] As a further description of the above technical solution:

[0017] The chip removal mechanism includes a negative pressure pump, which is fixedly connected to the outside of the base. The output end of the negative pressure pump is fixedly connected to a conveying pipe, and a dust collection box is placed outside the base.

[0018] As a further description of the above technical solution:

[0019] The dust collection box has a slip ring inside, and multiple sliding rods are slidably connected to the outside of the slip ring;

[0020] As a further description of the above technical solution:

[0021] A second connecting plate is fixedly connected to the outside of the sliding rod, and a connecting rod is fixedly connected to the outside of the second connecting plate.

[0022] As a further description of the above technical solution:

[0023] The connecting rod is externally fixedly connected to multiple anti-blocking plates, and the input end of the negative pressure pump is fixedly connected to a connecting pipe.

[0024] As a further description of the above technical solution:

[0025] The connecting pipe is externally fixedly connected to a connecting pipe, and the base is externally fixedly connected to a control box.

[0026] This utility model has the following beneficial effects:

[0027] 1. In this utility model, a hydraulic cylinder drives a transmission rod to move, which in turn causes a follower block to move a connecting plate. This, in turn, causes the clamping plate to slide within the guide groove, thereby achieving adaptive clamping and positioning. This method is suitable for various steel specifications, improving the versatility of the equipment. The clamping force can be adaptively adjusted, preventing damage to the workpiece due to excessive clamping force and avoiding workpiece displacement due to insufficient clamping force. Furthermore, it can adapt to dynamic positioning requirements under moving conditions, enhancing the stability of the equipment.

[0028] 2. In this invention, the negative pressure pump generates suction upon startup, quickly drawing milling debris into the dust collection box via a conveying pipe. The slip ring and slide rod in the chip removal assembly work together to ensure a smooth chip removal path. Simultaneously, the linked anti-blocking plate rotates as the chip suction port moves, effectively preventing debris from clogging the pipe inlet and avoiding interference from chip accumulation on the milling operation. This significantly improves processing efficiency and precision, bringing great convenience to steel milling work. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] A portable small steel milling machine, as described in the following figure Figures 1 to 3 The machine includes a base 1, which is a flat plate structure providing stable support for the entire machine. A support column 2 is fixedly connected to the outside of the base 1. A spindle motor 3 is rotatably connected to the outside of the support column 2. The spindle motor 3 is rotatably connected to the support column 2 via bearings and can rotate horizontally around the axis of the support column 2 to adjust the milling position. A follower plate 4 is fixedly connected to the outside of the spindle motor 3, rotating synchronously with the spindle motor 3. A milling table 5 is fixedly connected to the outside of the follower plate 4. An adjustment mechanism 6 is provided on the outside of the support column 2, and a chip removal mechanism 9 is provided on the outside of the base 1.

[0038] The adjustment mechanism 6 includes a guide groove 61 formed outside the milling table 5, which guides the clamping plate 62 to slide along a predetermined trajectory.

[0039] Specifically, according to the milling requirements, the spindle motor 3 can be rotated, which will drive the follower plate 4 and the milling table 5 to adjust their angle and position in the horizontal direction. Once the position is determined, the steel can be clamped by the adjustment mechanism 6, ready for milling operations.

[0040] Reference Figures 1 to 3The milling table 5 is externally slidably connected to a clamping plate 62, and internally slidably connected to a follower block 63. A connecting plate 64 is rotatably connected to the top of the follower block 63, and the other end of the connecting plate 64 is rotatably connected to the bottom of the clamping plate 62, used to transmit the displacement of the follower block 63, thereby driving the clamping plate 62 to move along the guide groove 61. A connecting plate 65 is rotatably connected to the bottom of the follower block 63, and the connecting plate 65 cooperates with a fixed rod 67 rotatably connected inside the opening groove 66, jointly providing auxiliary support and guidance for the sliding process of the follower block 63, ensuring its smooth movement. A support block 68 is fixedly connected to the outside of the support column 2, and a drive assembly 69 is fixedly connected to the support block 68. The drive assembly 69 includes a hydraulic cylinder 691, which is fixed to the support block 68, and its driving end is connected to a transmission rod 692, the other end of which is fixedly connected to the follower block 63. The milling table 5 has a rotatable connection between a positioning roller 7 and a milling cutter 8.

[0041] Specifically, the hydraulic cylinder 691 is activated, and its drive end pushes the transmission rod 692, which in turn drives the follower block 63 to slide inside the milling table 5. The follower block 63 pushes the clamping plate 62 to slide along the guide groove 61 through the connecting plate 64 at the top, clamping and fixing the steel placed on the positioning roller 7. Then, the spindle motor 3 is activated, driving the milling cutter 8 to rotate and perform milling operations on the steel.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The chip removal mechanism 9 includes a negative pressure pump 91, which is fixedly connected to the outside of the base 1. Its output end is connected to a conveying pipe 92, and its input end is connected to a connecting pipe 98. A connecting pipe 99 is connected to the outside of the connecting pipe 98, and the two together form a chip suction port. A dust collection box 10 is placed outside the base 1, and the end of the conveying pipe 92 extends into the dust collection box 10. Symmetrically arranged annular sliding rings 93 are provided on the open sidewall of the dust collection box 10, and a sliding rod 94 is slidably connected inside the sliding ring 93. The sliding rod 94 is fixedly connected to the connecting pipe 99 of the chip suction port and extends into the dust collection box 10. A second connecting plate 95 is fixedly connected to the outside of the sliding rod 94, and the second connecting plate 95 is fixedly connected to a connecting rod 96. An anti-blocking plate 97 is fixedly connected to the outside of the connecting rod 96. A control box 11 is also fixedly connected to the outside of the base 1, used to integrate electrical components such as the spindle motor 3, hydraulic cylinder 691, and negative pressure pump 91.

[0043] Specifically, at the start of the milling operation, the negative pressure pump 91 outside the base 1 is activated to generate suction. The steel chips generated during milling are sucked in through the chip suction port formed by the connecting pipe 98 and the connecting pipe 99, and then transported to the dust collection box 10 via the conveying pipe 92. During the operation, the operator can manually move the chip suction port as needed to optimally align it with the chip generation position. When the chip suction port is moved, the slide rod 94 fixed to it slides along the slip ring 93. This sliding is transmitted to the connecting rod 96 through the connecting plate 95, causing the connecting rod 96 to rotate, thereby driving the anti-blocking plate 97 to rotate synchronously. The rotating anti-blocking plate 97 can effectively disperse the clumps or accumulated steel chips in the dust collection box 10, thereby actively preventing the inlet of the conveying pipe 92 from becoming blocked and ensuring a continuous and smooth chip removal process.

[0044] The implementation principle of this embodiment is as follows: The hydraulic cylinder 691 is activated, causing its piston rod to extend and retract, pushing the transmission rod 692. This drives the follower block 63 to slide inside the milling table 5. The follower block 63, through the connecting plate 64, pushes the clamping plate 62 to move along the guide groove 61 until the clamping plate 62 clamps the steel. Then, the spindle motor 3 is activated, driving the milling cutter 8 to rotate at high speed. At this time, the steel is pushed to move along the positioning roller 7, and the rotating milling cutter 8 can then mill the edges of the steel.

[0045] During milling, the negative pressure pump 91 is activated to generate negative pressure suction. The steel chips generated during milling are sucked in through the chip suction port formed by the connecting pipe 98 and the connecting pipe 99, and then transported to the dust collection box 10 via the conveying pipe 92. During the chip removal process, to clear any blockages inside the dust collection box 10 and at the inlet of the conveying pipe 92, the chip suction assembly can be manually moved. The slide rod 94 of this assembly slides along the slip ring 93 and drives the connecting rod 96 to rotate via the connecting plate 95, causing the anti-blocking plate 97 to rotate accordingly. This effectively disperses and cleans the clumps of steel chips inside the dust collection box 10, preventing pipe blockage.

[0046] After milling is completed, turn off the spindle motor 3 and the negative pressure pump 91, and reverse the hydraulic cylinder 691 to release the clamping plate 62, allowing the machined steel to be removed. The dust collection box 10 is detachable for easy cleaning of the collected steel chips, completing all operations.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
