Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, and in particular to a machine tool anti-vibration milling cutter. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] Currently, when using existing milling cutters to mill the inner walls of narrow pipes, larger cutter heads are difficult to insert and cannot be used for milling. When using smaller cutter heads, the corresponding cutter shanks are usually also thinner, which makes the thinner cutters prone to vibration during milling, affecting the milling effect.

[0004] Therefore, this application provides a machine tool anti-vibration milling cutter to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a machine tool anti-vibration milling cutter to solve the problem in the prior art that milling cutters are prone to vibration when extended, which affects the milling effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A machine tool anti-vibration milling cutter includes a milling cutter shank and a milling cutter head. The milling cutter head has a cylindrical structure and includes a cutting edge and a shank. The shank is inserted into one end of the milling cutter shank. Several reinforcing ribs are fixed to the end of the milling cutter shank, and a groove is formed on the outer edge of the shank. The reinforcing ribs are engaged with the groove.

[0008] Optionally, the end of the milling cutter bar is provided with a slot for the tool holder to be inserted.

[0009] Optionally, three reinforcing ribs are provided and are evenly fixed to the inner wall of the slot.

[0010] Optionally, the outer edge of the handle portion is provided with three slots, which are evenly distributed along the outer edge of the handle portion.

[0011] Optionally, the milling cutter bar is provided with a fastening bolt, which is inserted into the milling cutter bar and fixed to the cutter shank.

[0012] Optionally, the end side of the milling cutter bar has at least two fixing holes, and two fastening bolts are provided, which are inserted into the milling cutter bar through the two fixing holes respectively.

[0013] Optionally, the surface of the tool holder is provided with a plurality of positioning holes at equal intervals along the axial direction, and the fastening bolt is threadedly engaged with the positioning holes at the corresponding positions.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, thanks to the combination of the milling cutter bar, the milling cutter head, and the reinforcing rib, the milling cutter head can be reinforced and its position limited during use, thereby improving the stability of milling.

[0016] In the above solution, thanks to the design of the slot, the fixing effect is ensured by the use of reinforcing ribs for snap-fit, and the fastening bolts are used for reinforcement, which facilitates the connection between the milling cutter shank and the milling cutter head.

[0017] In summary, this device can constrain the displacement of the milling cutter head, fundamentally reducing vibrations caused by cutter head wobbling and enhancing the overall stability of the milling cutter structure. Attached Figure Description

[0027] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0028] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0029] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0030] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0031] like Figure 1-4As shown, an embodiment of the present invention provides a machine tool anti-vibration milling cutter, including a milling cutter shank 1 and a milling cutter head 2, wherein the end of the milling cutter shank 1 is provided with a slot 101 for the tool holder portion 202 to be inserted.

[0032] Meanwhile, the milling cutter head 2 has a cylindrical structure and includes a cutting edge 201 and a handle 202. The handle 202 is inserted into one end of the milling cutter rod 1. The end of the milling cutter rod 1 is fixed with several reinforcing ribs 3. In this embodiment, three reinforcing ribs 3 are provided and are evenly fixed on the inner wall of the slot 101. The outer edge surface of the handle 202 is provided with a slot 204. The reinforcing ribs 3 are engaged with the slots 204. Specifically, the outer edge surface of the handle 202 is provided with three slots 204, and the three slots 204 are evenly distributed along the outer edge surface of the handle 202.

[0033] The milling cutter shank 1 is equipped with fastening bolts 5, which are inserted into the milling cutter shank 1 and fixedly connected to the tool holder portion 202. Specifically, at least two fixing holes 4 are provided on the side of the end of the milling cutter shank 1, and two fastening bolts 5 are provided, each inserted into the milling cutter shank 1 through one of the two fixing holes 4. In addition, a plurality of positioning holes 203 are provided at equal intervals along the axial direction on the surface of the tool holder portion 202, and the fastening bolts 5 are threadedly engaged with the corresponding positioning holes 203.

[0034] The working principle of this utility model is as follows: During milling, when the milling cutter is subjected to cutting force, the cutter head 2 tends to displace relative to the cutter shank 1. Due to the engaging engagement of the reinforcing rib 3 and the retaining groove 204 between the shank 202 and the cutter shank 1, the displacement of the shank 202 in the direction perpendicular to the retaining groove 204 is limited, thereby reducing the wobbling of the cutter head 2. Simultaneously, the threaded engagement of the fastening bolt 5 and the positioning hole 203 further restricts the axial displacement of the cutter head 2, enabling it to work more stably during milling and effectively reducing vibration.

[0035] In summary, this device can constrain the displacement of the milling cutter head 2, fundamentally reducing vibrations caused by cutter head wobbling and enhancing the overall stability of the milling cutter structure.

[0036] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
