Description

Technical Field

[0001] This utility model relates to an aluminum milling cutter, specifically an aluminum milling cutter with a spiral chip removal groove structure, belonging to the technical field of aluminum milling cutters. Background Technology

[0002] Aluminum and its alloys are widely used in aerospace, automotive manufacturing, and consumer electronics due to their low density, good thermal conductivity, and ease of machining. However, during milling, due to the high ductility of aluminum, chips tend to adhere to the tool surface, leading to heat buildup, increased tool wear, and even scratches on the machined surface. If chip removal is not smooth, waste chips may become entangled on the tool or workpiece, interfering with machining accuracy and even causing equipment downtime. To solve these problems, a spiral chip groove structure has been introduced into milling cutter design. Its core principle is to guide chips to be continuously discharged in a specific direction through the helix angle, reducing the contact time between chips and the tool and workpiece, thereby lowering the cutting temperature and improving machining efficiency.

[0003] However, most existing aluminum end mills have various problems. For example, in the aluminum end mill disclosed in publication number CN218487293U, although the unequal division of adjacent helix angles can reduce the fluctuations generated during cutting operations and improve the stability of cutting operations, and the double butterfly angle of the end cutting edge can prevent chipping when cutting in a straight line, thus reducing the risk of chipping and improving the working efficiency and service life of the end mill, in this technical solution and most current aluminum end mills, before milling operations, in order to increase the lubrication of the chip removal groove and avoid chip accumulation, it is generally necessary to manually apply lubricating oil to the surface of the end mill to assist in chip removal. This process is time-consuming and labor-intensive, and it is difficult to ensure the uniformity of the coating. At the same time, manual application requires frequent machine stops to replenish oil, which affects the efficiency of continuous processing. It is especially unsuitable for the high-paced requirements of automated production lines. Furthermore, excessive lubricating oil may seep into the machine tool, contaminating precision components such as guide rails and bearings, increasing maintenance costs. Oil residue on the workpiece surface requires additional cleaning, adding post-processing steps, which is not in line with the trend of green manufacturing. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing an aluminum milling cutter with a spiral chip removal groove structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum milling cutter with a spiral chip removal groove structure includes a support frame, a cylinder, a connecting seat, an aluminum milling cutter, and a coating assembly. The support frame is fixed on an external machine tool, the cylinder is fixed at the top center of the support frame, the connecting seat is connected to the telescopic part of the cylinder and located inside the support frame, and the aluminum milling cutter is locked on the connecting seat.

[0007] The coating assembly for applying lubricating oil is disposed within the support frame, and the coating assembly includes a linkage frame, a roller brush, and a reset unit. One end of the linkage frame is rotatably connected to the inner wall of one side of the support frame, the roller brush is rotatably connected to the other end of the linkage frame, and lubricating oil is disposed on the roller brush. The roller brush rolls against one side of the aluminum milling cutter, and the reset unit is disposed between the support frame and the linkage frame.

[0008] As a further embodiment of this utility model: the reset unit includes a docking rod, a limiting seat and a reset spring. The docking rod is fixed on the linkage frame, the limiting seat is fixed on the inner wall of the support frame, and one end of the reset spring is engaged with the docking rod and the other end is engaged with the limiting seat.

[0009] As a further improvement of this utility model: the two ends of the reset spring are symmetrically fixed with pull rings, and the two pull rings are respectively rotatably connected to the docking rod and the limiting seat.

[0010] As a further improvement of this utility model: an oil storage box is provided at the bottom of one side of the coating component inside the support frame, and the oil storage box contains lubricating oil.

[0011] As a further embodiment of this utility model: at least two sets of the coating components are provided in the support frame, and the two sets of coating components are symmetrically arranged with each other.

[0012] As a further improvement of this utility model: the telescopic part of the cylinder is provided with a retaining seat, and a retaining block is fixed on the connecting seat. The retaining block is engaged in the retaining seat and is detachably connected by screws.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, when the aluminum milling cutter is driven up and down by a cylinder, a roller brush is simultaneously driven to roll along the surface of the milling cutter, realizing the coordinated operation of lubricating oil application and machining. This solves the problem of inefficiency in manual operation. Furthermore, the mechanical coupling design between the application component and the movement trajectory of the aluminum milling cutter avoids the intervention of an additional power source, simplifies the complexity of the equipment, and improves the stability of the system. At the same time, the continuous rolling of the roller brush ensures that the lubricating oil evenly covers the surface of the spiral chip removal groove of the aluminum milling cutter, reducing abnormal chip removal caused by excessive or insufficient lubricant in certain areas. This technical solution, through mechanical linkage and structural innovation, embeds the lubricating oil application process into the milling process, which not only solves the efficiency bottleneck and uniformity problem of manual application, but also reduces maintenance costs and environmental pollution risks through precise oil control, providing technical support for efficient and green aluminum processing.

[0020] 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. Example 1

[0021] like Figures 1 to 4 As shown, an aluminum milling cutter with a spiral chip removal groove structure includes a support frame 1, a cylinder 2, a connecting seat 3, an aluminum milling cutter 4, and a coating assembly 5. The support frame 1 is fixed on an external machine tool, the cylinder 2 is fixed at the top center of the support frame 1, the connecting seat 3 is connected to the telescopic part of the cylinder 2 and is located inside the support frame 1, and the aluminum milling cutter 4 is locked on the connecting seat 3.

[0022] The coating assembly 5 for applying lubricating oil is installed inside the support frame 1. The coating assembly 5 includes a linkage frame 51, a roller brush 52 and a reset unit. One end of the linkage frame 51 is rotatably connected to the inner wall of one side of the support frame 1. The roller brush 52 is rotatably connected to the other end of the linkage frame 51. Lubricating oil is provided on the roller brush 52, and the roller brush 52 rolls against one side of the aluminum milling cutter 4. The reset unit is installed between the support frame 1 and the linkage frame 51.

[0023] The reset unit includes a docking rod 53, a limiting seat 54, and a reset spring 55. The docking rod 53 is fixed on the linkage frame 51, the limiting seat 54 is fixed on the inner wall of the support frame 1, and one end of the reset spring 55 is engaged with the docking rod 53, while the other end is engaged with the limiting seat 54.

[0024] At least two sets of coating components 5 are provided in the support frame 1, and the two sets of coating components 5 are arranged symmetrically to each other. The aluminum milling cutter 4 is located between two adjacent roller brushes 52 and rolls against the roller brushes 52.

[0025] In this invention, when the cylinder 2 drives the aluminum milling cutter 4 to move up and down, it simultaneously drives the roller brush 52 to roll along the surface of the milling cutter, achieving coordinated operation of lubricant application and machining. This solves the inefficiency problem of manual operation. Furthermore, the mechanical coupling design between the application component 5 and the movement trajectory of the aluminum milling cutter 4 avoids the need for an additional power source, simplifying equipment complexity and improving system stability. Simultaneously, the continuous rolling of the roller brush 52 ensures that the lubricant evenly covers the surface of the spiral chip removal groove of the aluminum milling cutter 4, reducing abnormal chip removal caused by excessive or insufficient lubricant in certain areas. This technical solution, through mechanical linkage and structural innovation, embeds the lubricant application process into the milling process, not only solving the efficiency bottleneck and uniformity problems of manual application but also reducing maintenance costs and environmental pollution risks through precise oil control, providing technical support for efficient and green aluminum processing. Example 2

[0026] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0027] The two ends of the return spring 55 are symmetrically fixed with pull rings 56, and the two pull rings 56 are rotatably connected to the docking rod 53 and the limit seat 54 respectively. The rotation of the pull rings 56 enables the linkage frame 51 to synchronously drive the angle of the return spring 55 to change accordingly when the linkage is activated.

[0028] An oil storage box 6 is provided at the bottom of one side of the brush assembly 5 inside the support frame 1. The oil storage box 6 contains lubricating oil, and the oil storage box 6 enables the roller brush 52 to automatically replenish the oil.

[0029] The telescopic part of cylinder 2 is provided with a retainer 7, and a retaining block 8 is fixed on the connecting seat 3. The retaining block 8 is engaged in the retainer 7 and is detachably connected by screws. Through the detachable connection structure, the aluminum milling cutter 4 can be quickly disassembled and replaced.

[0030] Working principle: When using this aluminum end mill, first connect the connecting seat 3 to the seat 7 via the locking block 8 and lock it with screws. During processing, the aluminum end mill 4 is driven to move by the cylinder 2. At the same time, the aluminum end mill 4 comes into contact with the roller brush 52. At this time, the roller brush 52 rolls on the surface of the aluminum end mill 4, so that the lubricating oil can be applied to the surface of the aluminum end mill 4. At the same time, the aluminum end mill 4 pushes the linkage frame 51 to rotate. After processing is completed, the aluminum end mill 4 moves in the opposite direction. At this time, the roller brush 52 is reset by the elastic force of the return spring 55.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
