Description

Technical Field

[0001] This utility model relates to the field of composite thread milling cutter technology with protective function, and in particular to a composite thread milling cutter with protective function. Background Technology

[0002] Traditional thread machining methods mainly involve turning threads with thread cutting tools or manually tapping and threading using taps and dies. With the development of CNC machining technology, especially the emergence of three-axis CNC machining systems, a more advanced thread machining method—CNC milling—has become possible. Compared with traditional thread machining methods, thread milling has significant advantages in machining accuracy and efficiency, and it is not limited by the thread structure or thread direction. For example, a single thread milling cutter can machine various internal and external threads with different directions.

[0003] A fixed protective cover is installed around the milling cutter. Its shape is adapted to the movement trajectory of the milling cutter. It can block the workpiece residue and debris from splashing. At the same time, when the tool accidentally comes into contact with non-machined areas (such as worktables and fixtures), the structural strength buffers the impact force of the collision and reduces the direct force on the tool.

[0004] While the above technologies achieve protection for the end mill, in actual use, adjusting the bolts of the traditional end mill and protective cover requires disassembling and tightening each bolt individually when adjusting the position of the protective cover. This operation is cumbersome and time-consuming. Therefore, a composite thread end mill with protective function is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a composite thread milling cutter with protective function, which aims to solve the problem that the bolt adjustment of traditional milling cutters and protective covers in the prior art requires disassembling and tightening the bolts one by one when adjusting the position of the protective cover, which is cumbersome and time-consuming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a composite thread milling cutter with protective function, comprising a milling cutter, a shank fixedly connected to the rear wall of the milling cutter, a protective shell provided on the outer wall of the shank, a groove rail provided on the outer wall of the protective shell, a sliding component provided inside the groove rail, a cleaning component provided on the outer wall of the protective shell, and a threaded sleeve fixedly connected to the rear wall of the protective shell.

[0007] The sliding assembly includes a slider, the outer wall of which is slidably connected to a groove rail, an anti-slip strip fixedly connected to the outer wall of the slider, a first ring fixedly connected to the rear wall of the slider, a second ring slidably connected to the inside of the protective shell, an elastic ball fixedly connected to the outer wall of the second ring, and a slot provided inside the protective shell.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the elastic ball is engaged inside the slot.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the first ring is slidably connected to the inside of the protective shell.

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

[0013] The inner ring of the second ring is attached to the outer wall of the handle.

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

[0015] The inner ring of the first ring is attached to the outer wall of the handle.

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

[0017] The cleaning assembly includes a first retaining ring, the inner ring of which is fixedly connected to the outer wall of the handle. A first retaining groove is formed inside the second ring. The outer wall of the handle is fixedly connected to the second retaining ring. The first ring has a second retaining groove inside. A brush is fixedly connected to the front outer wall of the protective shell.

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

[0019] The rear wall of the handle is fixedly connected to a second telescopic rod, the outer wall of the second telescopic rod is slidably connected to a first telescopic rod, the outer wall of the first telescopic rod is attached to the rear wall of the protective shell, and the outer wall of the second telescopic rod is slidably connected to the inside of the protective shell.

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

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting a slider, anti-slip strip, and a No. 1 ring, the slider is manually moved outward to remove the milling cutter from the protective shell. This ensures that the milling cutter is promptly retracted when it is not in operation to prevent damage from impacts.

[0024] 2. In this utility model, by setting a first retaining ring, a second retaining ring, and a brush, the milling cutter is moved out, and then the first telescopic rod is held and rotated to drive the milling cutter to rotate.

Detailed Implementation

[0031] 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.

[0032] Reference Figures 1-3 An embodiment of this utility model is provided: a composite thread milling cutter with protective function, including a milling cutter 1, a shank 2 fixedly connected to the rear wall of the milling cutter 1, a protective shell 3 provided on the outer wall of the shank 2, which can shield and protect a part of the shank 2 and the milling cutter 1, a groove 4 provided on the outer wall of the protective shell 3, which provides a path and guide for the sliding component 6 to slide and ensures that the sliding component 6 can move stably, the sliding component 6 is provided inside the groove 4, a cleaning component 7 is provided on the outer wall of the protective shell 3, and a threaded sleeve 5 fixedly connected to the rear wall of the protective shell 3, which facilitates the installation and fixing of the protective shell 3 on the corresponding equipment or position;

[0033] The sliding assembly 6 includes a slider 61, the outer wall of which is slidably connected to the groove rail 4. An anti-slip strip 62 is fixedly connected to the outer wall of the slider 61 to increase friction when the operator pushes the slider 61 and prevent hand slippage. A first ring 63 is fixedly connected to the rear wall of the slider 61. A second ring 65 is slidably connected inside the protective shell 3. An elastic ball 64 is fixedly connected to the outer wall of the second ring 65. The elastic ball 64 is elastic and can be locked into a slot 66 for positional fixation. A slot 66 is provided inside the protective shell 3, and the outer wall of the elastic ball 64 is engaged inside the slot 66. The outer wall of the first ring 63 is slidably connected inside the protective shell 3. The protective shell 3 is installed and fixed via a threaded sleeve 5. The sliding assembly 6 inside can flexibly adjust the protection range: when the slider 61 is pushed, the slider 61 slides along the groove rail 4, causing the first ring 63 to slide synchronously inside the protective shell 3 and on the outer wall of the handle 2. The anti-slip strip 62 increases friction during operation, facilitating the application of force. At the same time, the second ring 65, which is linked with the first ring 63, moves together with it. During the movement, the elastic ball 64 on the outer wall of the second ring 65 will be inserted into the slots 66 at different positions inside the protective shell 3, thereby fixing the positions of the first ring 63 and the second ring 65, and thus adjusting the protective coverage of the protective shell 3 on the tool holder 2 and the end mill 1.

[0034] Reference Figures 2-4 The inner ring of the second ring 65 is attached to the outer wall of the tool holder 2, and the inner ring of the first ring 63 is attached to the outer wall of the tool holder 2. The cleaning assembly 7 includes a first retaining ring 71, which serves to position and facilitate rotation. The inner ring of the first retaining ring 71 is fixedly connected to the outer wall of the tool holder 2. A first retaining groove 72 is formed inside the second ring 65. A second retaining ring 74 is fixedly connected to the outer wall of the tool holder 2. A second retaining groove 73 is formed inside the first ring 63. A brush 75 is fixedly connected to the front outer wall of the protective shell 3, which can clean the outer wall of the end mill 1 when it rotates. A second telescopic rod 9 is fixedly connected to the rear wall of the tool holder 2. A first telescopic rod 8 is slidably connected to the outer wall of the second telescopic rod 9. The outer wall of rod 8 is attached to the rear wall of protective shell 3. The outer wall of the second telescopic rod 9 is slidably connected to the inside of protective shell 3. The outer wall of the first slot 72 is rotatably connected to the inside of the first retaining ring 71. The outer wall of the second retaining ring 74 is rotatably connected to the inside of the second slot 73. The outer wall of milling cutter 1 is attached to the inside of brush 75. First, move milling cutter 1 to the position inside brush 75, and then manually rotate the first telescopic rod 8 to rotate, so that the first retaining ring 71 connected to the outer wall of the handle 2 rotates inside the first slot 72. At the same time, the second retaining ring 74 rotates outside the second slot 73 to ensure stable movement. The brush 75 at the front end of protective shell 3 is always attached to the outer wall of milling cutter 1, so that the outer wall of milling cutter 1 is cleaned by the rotation of brush 75.

[0035] Working principle: When in use, the protective shell 3 is installed and fixed through the threaded sleeve 5. The sliding component 6 inside can flexibly adjust the protection range: When the slider 61 is pushed, the slider 61 slides along the groove rail 4, which drives the first ring 63 to slide synchronously inside the protective shell 3 and on the outer wall of the handle 2. The anti-slip strip 62 can increase the friction during operation and facilitate the application of force. Simultaneously, the second ring 65, which is linked to the first ring 63, moves along with it. During the movement, the elastic ball 64 on the outer wall of the second ring 65 will be inserted into the slots 66 at different positions inside the protective shell 3, thereby fixing the positions of the first ring 63 and the second ring 65, and adjusting the protective coverage of the protective shell 3 on the tool holder 2 and the end mill 1. First, the end mill 1 is moved to the position inside the brush 75, and then the first telescopic rod 8 is manually rotated, so that the first retaining ring 71 connected to the outer wall of the tool holder 2 rotates inside the first slot 72, while the second retaining ring 74 rotates outside the second slot 73, ensuring that the movement process is stable. The brush 75 at the front end of the protective shell 3 always adheres to the outer wall of the end mill 1, so that the outer wall of the end mill 1 is cleaned by the rotation of the brush 75.

[0036] 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.
