Description

Technical Field

[0001] This utility model relates to the field of parts processing equipment technology, specifically to an anti-vibration milling cutter bar and its milling cutter. Background Technology

[0002] Milling is a common machining method widely used in manufacturing. During milling, the milling cutter is one of the core components, and its performance directly affects machining accuracy and efficiency.

[0003] Traditional milling cutter mounting methods mainly fall into two categories: one is to weld the milling cutter directly to the cutter shank, and the other is to connect the milling cutter to the cutter shank with bolts. Because milling generates severe vibrations, these vibrations are transmitted to the milling cutter through the cutter shank, leading to instability in the milling cutter's working condition. This instability not only affects the surface quality of the machined workpiece but also reduces machining accuracy. Furthermore, long-term vibration can accelerate cutter wear and may even cause cutter damage, thus increasing production costs and maintenance time. Therefore, we propose an anti-vibration milling cutter shank and its corresponding milling cutter to address these problems. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A vibration-damping milling cutter bar, comprising:

[0006] The mounting rod has a fixed base at one end, and the internal structure of the mounting rod has a mounting groove. The top center of the mounting rod has a slot that communicates with the mounting groove.

[0007] The milling cutter body and the connecting plate are slidably inserted into the interior of the mounting groove. The milling cutter body is fixed at one end of the connecting plate located outside the mounting groove. A rectangular channel is constructed in the middle of the connecting plate.

[0008] A limiting plate is inserted inside the slot and slides through the rectangular channel;

[0009] A locking element is provided on the outer surface of the mounting rod, the locking element being used to prevent the limiting plate from disengaging from the mounting groove;

[0010] A shock-absorbing component is disposed on the inner bottom wall of the mounting groove, and the shock-absorbing component is used to buffer vibration impact.

[0011] Furthermore, the shock absorption assembly includes a sliding plate that slides inside the mounting groove, with buffer springs connecting the two sides of the sliding plate to the inner bottom wall of the mounting groove, and a damping rod provided between the middle of the sliding plate and the inner bottom wall of the mounting groove.

[0012] Furthermore, epoxy resin adhesive is applied to the bottom of both sides of the limiting plate.

[0013] Furthermore, the end of the mounting rod away from the fixed seat is provided with a groove, and the end of the milling cutter body near the connecting plate is fitted with a butyl rubber ring, which is embedded inside the groove.

[0014] Furthermore, the locking element includes a retaining ring fixedly disposed at a slot, and a locking sleeve is slidably fitted onto the surface of the mounting rod.

[0015] Furthermore, the top of the limiting plate is arc-shaped, and a lifting groove is constructed on one side of it.

[0016] This utility model also provides a milling cutter, including the milling cutter shank described above.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention incorporates a shock-absorbing component inside the mounting rod. When the milling cutter encounters impact during operation, the force is first applied to the cutter body and then transmitted to the mounting rod via the connecting plate. At this time, the sliding plate slides within the mounting groove, compressing the connected buffer spring and generating resistance through the damping rod. This effectively converts vibration energy into heat or other forms of energy, reducing vibration transmission during milling and enabling the milling cutter to work more stably, thereby improving the surface quality and overall precision of the machined parts.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides an anti-vibration milling cutter shank and the same, primarily addressing the problem in existing technologies where severe vibrations occur during milling, transmitted through the shank to the milling cutter, leading to instability in the cutter's operation. This instability not only affects the surface quality of the workpiece but also reduces machining accuracy. Furthermore, prolonged vibration can accelerate cutter wear and even cause damage. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0027] A vibration-damping milling cutter bar, comprising:

[0028] Mounting rod 1, with a fixing seat 2 fixed at one end, the internal structure of mounting rod 1 having mounting groove 101, and the top middle of mounting rod 1 having a slot 102 communicating with mounting groove 101;

[0029] The milling cutter body 3 and the connecting plate 4 are slidably inserted inside the mounting groove 101. The milling cutter body 3 is fixed at one end of the connecting plate 4 located outside the mounting groove 101. A rectangular channel 401 is constructed in the middle of the connecting plate 4.

[0030] The limiting plate 5 is inserted inside the slot 102 and slides through the rectangular channel 401;

[0031] A locking element 6 is disposed on the outer surface of the mounting rod 1, and the locking element 6 is used to prevent the limiting plate 5 from disengaging from the mounting groove 101;

[0032] A shock-absorbing component 7 is disposed on the inner bottom wall of the mounting groove 101. The shock-absorbing component 7 is used to buffer vibration impact. The shock-absorbing component 7 includes a sliding plate 701 that slides through the inside of the mounting groove 101. Buffer springs 702 are connected between the two sides of the sliding plate 701 and the inner bottom wall of the mounting groove 101. A damping rod 703 is disposed between the middle of the sliding plate 701 and the inner bottom wall of the mounting groove 101.

[0033] Workflow Description:

[0034] Installation phase:

[0035] The milling cutter body 3 is inserted into the mounting slot 101 of the mounting rod 1 via the connecting plate 4;

[0036] Insert the limiting plate 5 into the slot 102 and slide it through the rectangular channel 401 on the connecting plate 4 to fix the position of the connecting plate 4.

[0037] The limiting plate 5 is fixed in the mounting groove 101 by the locking member 6 to prevent it from falling off;

[0038] The shock absorption component 7 is disposed inside the mounting groove 101 to absorb and buffer vibrations generated during operation.

[0039] Work phase:

[0040] When the milling cutter starts working, the vibration experienced by the milling cutter body 3 will be transmitted to the mounting rod 1 through the connecting plate 4;

[0041] The limiting plate 5 restricts excessive movement of the connecting plate 4, and the shock absorption component 7 can absorb most of the vibration energy.

[0042] This anti-vibration milling cutter rod incorporates a damping component 7 inside the mounting rod 1. When the milling cutter encounters impact during operation, the force first acts on the cutter body 3 and is then transmitted to the mounting rod 1 via the connecting plate 4. At this time, the sliding plate 701 slides within the mounting groove 101, compressing the connected buffer spring 702 and generating resistance through the damping rod 703, thereby converting vibration energy into heat energy or other forms of energy for dissipation. Simultaneously, the limiting plate 5 restricts excessive movement of the connecting plate 4, further ensuring the stability of the milling cutter and effectively reducing vibration transmission during milling. This allows the milling cutter to work more stably, thereby improving the surface quality and overall precision of the machined parts.

[0043] like Figure 3 As shown, in some embodiments, the bottom sides of the limiting plate 5 are coated with epoxy resin adhesive 501. More specifically, the epoxy resin adhesive 501 coating formed on the bottom sides of the limiting plate 5 can disperse and absorb vibration energy when the vibration waves generated during milling are transmitted to the limiting plate 5. When the vibration waves encounter the epoxy resin adhesive 501 layer, the adhesive layer can convert the vibration energy into heat energy or other forms of energy through the deformation of its molecular structure and internal friction, thereby reducing the transmission of vibration energy. At the same time, the epoxy resin adhesive has a certain degree of viscosity and elasticity. This characteristic allows it to form a damping structure between the limiting plate 5 and the mounting rod 1. During the operation of the milling cutter, when the limiting plate 5 slides or vibrates slightly relative to the mounting rod 1, the epoxy resin adhesive 501 layer will generate internal damping force to resist such sliding or vibration, thereby further reducing the amplitude and frequency of vibration.

[0044] like Figure 4As shown, in some embodiments, the end of the mounting rod 1 away from the fixed seat 2 is provided with a groove 103, and the end of the milling cutter body 3 near the connecting plate 4 is fitted with a butyl rubber ring 301. The butyl rubber ring 301 is embedded inside the groove 103. More specifically, the butyl rubber ring 301 is precisely embedded inside the groove 103, forming a tight and uniquely functional connection structure. This design not only enhances the overall stability of the milling cutter assembly, but also greatly improves its shock absorption effect. In addition, butyl rubber has excellent airtightness and watertightness, which can effectively prevent moisture, dust and impurities from entering the milling cutter rod.

[0045] like Figure 1 As shown, in some embodiments, the locking member 6 includes a fixing ring 601 fixed at one slot of the slot 102, and a locking sleeve 602 is slidably sleeved on the surface of the mounting rod 1. More specifically, the locking sleeve 602 is first slid to the top of the mounting rod 1. After the limiting plate 5 is inserted into the mounting slot 101, the locking sleeve 602 slides down to the position of the fixing ring 601 under the action of gravity, which can prevent the limiting plate 5 from disengaging from the slot 102. This installation method is simple to operate and highly practical.

[0046] like Figure 1 As shown, in some embodiments, the top of the limiting plate 5 is arc-shaped, and a lifting groove 502 is constructed on one side. More specifically, the top of the limiting plate 5 is arc-shaped so that it can fully abut against the locking sleeve 602 to prevent the limiting plate 5 from loosening. The lifting groove 502 can facilitate the disassembly of the limiting plate 5 by the staff.

[0047] This utility model also provides a milling cutter, including the milling cutter shank described above. More specifically, compared with traditional milling cutters, the milling cutter provided by this device uses the vibration damping component 7 to absorb and buffer the vibration from the milling process, reducing the amount of vibration transmitted to the workpiece, improving the machining quality and protecting the tool from damage.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
