Description

Technical Field

[0001] This utility model belongs to the field of milling cutter processing technology, and in particular relates to a positioning structure for milling cutter spiral groove processing. Background Technology

[0002] As is well known, a milling cutter is a rotating cutting tool with multiple cutting teeth, widely used in milling operations. During the cutting process, its cutting teeth sequentially and intermittently remove the workpiece allowance, mainly used for machining planes, steps, grooves, shaped surfaces, and cutting off workpieces on milling machines. In the manufacturing of milling cutters, the helical grooves are usually precision ground using a grinding machine.

[0003] Due to the complex shape and varied angles of spiral grooves, the current machining process often faces the problem that the angle of the machining head cannot be effectively adjusted, making it difficult to adapt to the machining requirements of different groove types, thus affecting the groove accuracy and machining efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a positioning structure for machining helical grooves with a milling cutter, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A milling cutter spiral groove machining positioning structure includes a mounting base. The mounting base is provided with a milling cutter fixing component, a machining moving component, and a machining adjustment component. The milling cutter fixing component is located on the top side of the mounting base, the machining moving component is located beside the milling cutter fixing component, and the machining adjustment component is disposed on the machining moving component. The machining adjustment component and the machining moving component are slidably engaged. A machining dust extraction component is provided inside the mounting base.

[0007] In a further technical solution, the milling cutter fixing assembly includes a fixing seat, an automatic three-jaw chuck, a drive shaft, and a drive component. The fixing seat is located on top of the mounting base, the drive shaft is rotatably connected to the fixing seat, the automatic three-jaw chuck is located at one end of the drive shaft, and the drive component is located inside the fixing seat and is drively connected to the drive shaft.

[0008] A further technical solution includes a processing moving component comprising a placement frame, a moving motor, a moving block, a moving lead screw shaft, and two slide rails. The placement frame is located on top of the mounting base, the moving motor is located inside the placement frame, both ends of the moving lead screw shaft are rotatably connected to the placement frame and the moving lead screw shaft is drively connected to the moving motor, the two slide rails are symmetrically arranged inside the placement frame, the moving block is threadedly connected to the moving lead screw shaft, the moving block slides with the two slide rails, and the moving block is provided with a moving groove.

[0009] A further technical solution includes a processing and adjustment assembly comprising a moving cylinder, a moving frame, an adjusting cylinder, a sliding sleeve, a vertical plate, an adjusting plate, and a connecting plate. The moving frame is slidably connected within a moving groove. The moving cylinder is horizontally positioned within the moving groove, and its telescopic end is connected to the moving frame. The moving frame has a horizontally positioned moving column, and the moving column has two sliders. The adjusting cylinder is horizontally positioned on the moving frame. The sliding sleeve is slidably connected to the moving column and slidably engages with the two sliders. The telescopic end of the adjusting cylinder is connected to the bottom of the sliding sleeve. The vertical plate is connected to the top of the sliding sleeve. The middle position of the adjusting plate is hinged to the end of the moving column. The two ends of the connecting plate are respectively hinged to the vertical plate and the adjusting plate.

[0010] A further technical solution is that an automatic grooving head is installed at the bottom of the adjustment plate.

[0012] The beneficial effects of this utility model are:

[0013] In the processing of this invention, if the lateral position of the automatic grooving head needs to be adjusted, the moving cylinder is activated. Its telescopic end pushes the moving frame to slide within the moving groove of the moving block, thereby driving the entire processing adjustment assembly and the automatic grooving head to achieve lateral fine-tuning, allowing the processing head to more accurately approach the milling cutter's processing area. When the angle of the automatic grooving head needs to be adjusted to adapt to the different angles of the helical grooves on the milling cutter, the adjusting cylinder is activated. Its telescopic end pushes the sliding sleeve to slide on the moving column. Due to the sliding engagement between the sliding sleeve and two sliders, the sliding of the sliding sleeve will drive the vertical plate to move. When the vertical plate moves, the connecting plate pulls the adjusting plate to rotate around the end of the moving column, thereby realizing the angle adjustment of the automatic grooving head installed at the bottom of the adjusting plate. The operator can precisely control the telescopic amount of the adjusting cylinder according to the specific angle requirements of the helical groove on the milling cutter to achieve the required processing angle. It can precisely adjust the angle of the automatic grooving head and flexibly adapt to the processing of helical grooves with various complex angles. This multi-angle, high-precision adjustment capability completely solves the pain point of the inability to effectively adjust the cutter angle in existing machining processes. It enables the same set of equipment to process helical grooves of different groove types and angles, greatly improving the equipment's versatility and machining adaptability. At the same time, the precision of the angle adjustment also ensures the angular accuracy of the groove, reducing product scrap caused by angular deviations and further improving machining quality and efficiency.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please refer to Figure 1-5 As shown; this utility model provides a technical solution for a positioning structure for machining helical grooves of a milling cutter: a positioning structure for machining helical grooves of a milling cutter includes a mounting base 1, on which a milling cutter fixing component 2, a machining moving component 3, and a machining adjustment component 4 are provided. The milling cutter fixing component 2 is located on one side of the top of the mounting base 1, the machining moving component 3 is located beside the milling cutter fixing component 2, the machining adjustment component 4 is disposed on the machining moving component 3, and the machining adjustment component 4 and the machining moving component 3 are slidably engaged. A machining dust extraction component 5 is provided inside the mounting base 1.

[0023] In this embodiment, refer to Figure 2As shown, the milling cutter fixing assembly 2 includes a fixing base 21, an automatic three-jaw chuck 22, a drive shaft 23, and a drive component 24. The fixing base 21 is located on the top of the mounting base 1. The drive shaft 23 is rotatably connected to the fixing base 21. The automatic three-jaw chuck 22 is located at one end of the drive shaft 23. The drive component 24 is located inside the fixing base 21 and is drively connected to the drive shaft 23.

[0024] It should be noted that the automatic three-jaw chuck 22 is hydraulically driven; the drive component 24 is a motor that drives the drive shaft 23 to rotate.

[0025] During machining, the end mill to be machined is first placed within the clamping range of the automatic three-jaw chuck 22. The automatic three-jaw chuck 22 automatically centers and clamps the end mill, ensuring that the end mill does not deviate radially during machining. Next, the drive unit 24 starts, and its output power is transmitted to the drive shaft 23 through the transmission structure. The drive shaft 23 drives the connected automatic three-jaw chuck 22 and the clamped end mill to rotate. Furthermore, the drive unit 24 can precisely control the rotational speed of the drive shaft 23 according to machining requirements, thereby achieving helical groove machining at different speeds to adapt to milling scenarios with different materials and groove shapes.

[0026] The automatic three-jaw chuck 22 enables automatic centering and clamping of the milling cutter, effectively avoiding centering deviations that may occur during manual clamping and ensuring the coaxiality of the milling cutter during machining. Simultaneously, the drive unit 24 precisely controls the milling cutter's rotational speed, ensuring a stable and appropriate cutting speed throughout the cutting process. This reduces problems such as high surface roughness and low dimensional accuracy in grooves caused by improper rotational speed. Furthermore, stable rotation and secure fixing reduce milling cutter vibration during machining, further improving groove machining accuracy. It also reduces milling cutter wear, extends milling cutter life, and indirectly improves machining efficiency, effectively addressing the pain points in the prior art where the fixing and rotation of the milling cutter affect machining accuracy.

[0027] In this embodiment, refer to Figure 3 As shown, the processing moving assembly 3 includes a placement frame 31, a moving motor 32, a moving block 33, a moving lead screw shaft 34, and two slide rails 35. The placement frame 31 is located on top of the mounting base 1. The moving motor 32 is located inside the placement frame 31. The two ends of the moving lead screw shaft 34 are rotatably connected inside the placement frame 31, and the moving lead screw shaft 34 is drively connected to the moving motor 32. The two slide rails 35 are symmetrically arranged inside the placement frame 31. The moving block 33 is threadedly connected to the moving lead screw shaft 34. The moving block 33 slides against the two slide rails 35. The moving block 33 is provided with a moving groove 36.

[0028] When the machining position needs to be adjusted, the moving motor 32 starts and drives the moving lead screw shaft 34 to rotate within the placement frame 31. Since the moving block 33 is threadedly connected to the moving lead screw shaft 34, and the moving block 33 is simultaneously slidably engaged with two symmetrically arranged slide rails 35, the moving block 33 will move linearly along the slide rails 35 under the rotation of the moving lead screw shaft 34. By controlling the forward and reverse rotation of the moving motor 32, the moving block 33 can be moved back and forth along the slide rails 35, thereby driving the machining adjustment component 4 and the automatic grooving head 6 mounted on the moving block 33 to achieve lateral adjustment of their positions, so as to meet the machining requirements of helical grooves at different positions of the milling cutter.

[0029] In this embodiment, refer to Figure 4 As shown, the processing adjustment assembly 4 includes a moving cylinder 41, a moving frame 42, an adjusting cylinder 43, a sliding sleeve 44, a vertical plate 45, an adjusting plate 46, and a connecting plate 47. The moving frame 42 is slidably connected in the moving groove 36. The moving cylinder 41 is horizontally arranged in the moving groove 36, and its telescopic end is connected to the moving frame 42. The moving frame 42 is provided with a horizontally arranged moving column 48, and the moving column 48 is provided with two sliders 49. The adjusting cylinder 43 is horizontally arranged on the moving frame 42. The sliding sleeve 44 is slidably connected to the moving column 48 and slidably engaged with the two sliders 49. The telescopic end of the adjusting cylinder 43 is connected to the bottom of the sliding sleeve 44. The vertical plate 45 is connected to the top of the sliding sleeve 44. The middle position of the adjusting plate 46 is hinged to the end of the moving column 48. The two ends of the connecting plate 47 are respectively hinged to the vertical plate 45 and the adjusting plate 46. An automatic grooving head 6 is installed at the bottom of the adjusting plate 46.

[0030] During processing, if the lateral position of the automatic grooving head 6 needs to be adjusted, the moving cylinder 41 is activated, and its telescopic end pushes the moving frame 42 to slide within the moving groove 36 of the moving block 33. This drives the entire processing adjustment assembly 4 and the automatic grooving head 6 to achieve lateral fine-tuning, allowing the processing head to more accurately approach the milling cutter's processing area. When the angle of the automatic grooving head 6 needs to be adjusted to accommodate the different angles of the helical grooves on the milling cutter, the adjusting cylinder 43 is activated, and its telescopic end pushes the sliding sleeve 44 to slide on the moving column 48. Since the sliding sleeve 44 is in sliding engagement with the two sliders 49, the sliding of the sliding sleeve 44 will drive the vertical plate 45 to move. When the vertical plate 45 moves, the connecting plate 47 pulls the adjusting plate 46 to rotate around the end of the moving column 48, thereby achieving the angle adjustment of the automatic grooving head 6 installed at the bottom of the adjusting plate 46. The operator can precisely control the extension and retraction of the cylinder 43 according to the specific angle requirements of the helical groove on the milling cutter to achieve the required machining angle. This allows for precise adjustment of the angle of the automatic grooving head 6, flexibly adapting to the machining of helical grooves with various complex angles. This multi-angle, high-precision adjustment capability completely solves the pain point of the inability to effectively adjust the cutter head angle in existing machining processes. It enables the same equipment to process helical grooves of different groove types and angles, greatly improving the equipment's versatility and machining adaptability. Simultaneously, the precision of the angle adjustment ensures the angular accuracy of the groove, reducing product scrap due to angular deviations and further improving machining quality and efficiency.

[0031] In this embodiment, refer to Figure 5 As shown, the processing dust collection component 5 includes an adsorption net 51 and three adsorption fans 52. The top of the mounting base 1 is provided with an installation groove, and the three adsorption fans 52 are equally spaced in the installation groove. The adsorption net 51 is horizontally positioned at the top of the installation groove.

[0032] During the machining of the spiral groove of the milling cutter, three adsorption fans 52 are activated. These fans generate negative pressure, drawing the dust and debris from the machining area into the mounting slot. During this process, the adsorption screen 51 filters the dust and debris, preventing larger debris from entering the adsorption fans 52 and damaging them. It also traps the dust and debris on the screen 51 for easy cleaning later. The three adsorption fans 52 are evenly spaced to ensure a uniform negative pressure area at the top of the mounting base 1, guaranteeing comprehensive adsorption of dust and debris from the machining area and avoiding any dead zones.
