Description

Technical Field

[0001] This application relates to the field of cutting tool technology, and in particular to a metal cutting tool with a vibration damping component. Background Technology

[0002] Cutting tools are common tools in the field of machining. The structure of a cutting tool is mostly composed of a tool head and a tool shank. The tool head is mainly used for cutting and calibration, while the tool shank is used for being held by a fixture.

[0003] The cutting tool is subjected to a large lateral force during cutting, which easily generates strong vibration. Tool vibration directly affects the surface roughness, dimensional and positional accuracy of the product, thus affecting the machining quality. Therefore, further improvement is needed. Summary of the Invention

[0004] In order to improve the problem of vibration generated by existing cutting tools during the cutting process, the purpose of this application is to provide a metal cutting tool with vibration damping components.

[0005] The metal cutting tool with vibration damping component provided in this application adopts the following technical solution:

[0006] A metal cutting tool with a vibration damping component includes a head and a shank. The head includes an insert and a shank. The insert is mounted on the shank, and the shank is mounted on the shank. A first vibration chamber is formed in the shank, and a second vibration chamber is formed in the shank. The first and second vibration chambers communicate with each other. A first damping block is disposed in the first vibration chamber, and a second damping block is disposed in the second vibration chamber. An abutment block and a first telescopic spring are disposed between the first and second damping blocks. The end of the abutment block away from the first telescopic spring abuts against the first damping block, and the end of the first telescopic spring away from the abutment block is connected to the second damping block. The abutment block is connected to the first telescopic spring. The first and second vibration chambers are filled with damping oil. The cross-sections of the first and second vibration chambers are both circular. The first and second damping blocks are cylindrical. The outer diameter of the first damping block is smaller than the inner diameter of the first vibration chamber, and the outer diameter of the second damping block is smaller than the inner diameter of the second vibration chamber.

[0007] By adopting the above technical solution, when in use, the tool holder is clamped by an external clamp, and the blade faces the object being cut. When the blade is cutting, the vibration is transmitted to the first vibration chamber and the second vibration chamber. The damping oil inside immediately reduces part of the vibration. At the same time, the first damping block and the second damping block move under the action of the damping oil. The abutment and the first telescopic spring realize the buffering effect of the collision between them. The vibration energy can be absorbed and canceled, thereby eliminating the vibration energy and achieving the effect of vibration reduction.

[0008] The outer diameter of the first damping block is smaller than the inner diameter of the first vibration chamber, and the outer diameter of the second damping block is smaller than the inner diameter of the second vibration chamber. By utilizing the circular structure of both the first and second vibration chambers, the first and second damping blocks can achieve a large amplitude of movement during the movement of the damping oil, thereby reducing the impact of vibration on the machining of the cutting tool and improving the machining accuracy of the cutting tool.

[0009] Optionally, a transition cavity is provided at one end of the tool bar facing the tool holder. The transition cavity is located between the first vibration cavity and the second vibration cavity. The cross-section of the transition cavity is circular. The inner diameter of the transition cavity is smaller than the inner diameter of the first vibration cavity. The abutment block and the first telescopic spring are located in the transition cavity. The first damping block is movably inserted into the transition cavity.

[0010] By adopting the above technical solution, the transition cavity serves several purposes: first, it facilitates the installation of the abutment block and the first telescopic spring; second, when the first damping block passes through the transition cavity and abuts against the abutment block, the inner diameter of the transition cavity is smaller than that of the first vibration cavity, resulting in a higher local pressure of the damping oil in the transition cavity when it is simultaneously squeezed by the first and second damping blocks. This increases the counterforce on the first and second damping blocks under the elasticity of the first telescopic spring, thus better offsetting vibration energy and achieving faster efficiency; third, the pressure generated instantaneously in the transition cavity effectively pushes the first damping block away from the transition cavity and completely displaces it into the first vibration cavity, thereby achieving multi-directional reciprocating vibration damping.

[0011] Optionally, an oil injection hole is provided at the end of the tool holder away from the tool bar, a fixed plug is provided on the oil injection hole, and a second telescopic spring is provided at the end of the fixed plug facing the second damping block. The second telescopic spring extends into the second vibration chamber and movably abuts against the second damping block.

[0012] By adopting the above technical solution, damping oil is injected through the oil injection hole, and at the same time, leakage is prevented by the fixed plug. The second telescopic spring is used to abut against the second damping block, so that when the second damping block contacts the second telescopic spring, it can achieve a reverse damping effect. With the cooperation of the first telescopic spring, the process of successively damping the left and right movements is realized.

[0013] Optionally, the handle is provided with a T-shaped groove on the inner wall of the second vibration chamber, and a damping strip is slidably connected in the T-shaped groove. The damping strip includes a fixed rod and several frayed strips. Each frayed strip is connected to the fixed rod, the fixed rod is slidably connected in the T-shaped groove, and the frayed strips abut against the periphery of the second damping block.

[0014] By adopting the above technical solution, the damping strip is installed in the T-slot, and the wadding strip abuts against the outer periphery of the second damping block. When the second damping block is moving, the wadding strip can continuously abut against the periphery of the second damping block, quickly decelerating or stopping the second damping strip, and the anti-seismic effect is more obvious.

[0015] Optionally, the length of the fixing rod is less than the length of the T-groove, and when the second damping block abuts against the wadding strip, the fixing rod slides along the T-groove.

[0016] By adopting the above technical solution, the length of the fixed rod is less than the length of the T-slot, so that when the second damping block abuts against the wadding strip, the wadding strip can push the fixed rod to slide back and forth along the T-slot, so that the second damping block can achieve a certain buffering effect during the motion damping process, which is beneficial for process-assisted damping.

[0017] Optionally, the damping strip is made of rubber, and the strip is integrally formed with the fixing rod.

[0018] By adopting the above technical solution, the damping strip is made of rubber material, which will not generate a fast movement speed during the sliding process of the T-slot, and has a certain friction force, which is convenient for assisting in shock absorption. At the same time, the strip abuts against the second damping block, which also has a certain friction force and a certain degree of softness, thus achieving a better shock absorption effect. The strip and the fixing rod are integrally formed, and the overall structure is stable and not easy to break.

[0019] Optionally, a cooling chamber is provided above the first vibration chamber of the tool holder, and the cooling chamber is connected to both the first vibration chamber and the second vibration chamber.

[0020] By adopting the above technical solution and utilizing the cooling chamber, the damping oil tends to heat up over time during the shaking process. When it overflows into the cooling chamber, the surface temperature of the damping oil can be effectively reduced by utilizing the area of ​​the cooling chamber, thereby improving the service life of the cutting tool.

[0021] Optionally, a sealing ring is provided at the end of the tool bar facing the tool holder, and the tool bar and the tool holder are connected by fasteners.

[0022] By adopting the above technical solution, the sealing ring is made so that the damping oil is not easy to leak out from the connection between the tool holder and the tool shank, and the connection is fixed by fasteners.

[0023] Optionally, the blade is mounted on the end of the tool holder away from the handle. The tool holder has a mounting cavity, the blade is located in the mounting cavity and hinged to the tool holder, and the tool holder has an abutment on the side of the blade. The abutment includes an adjusting member and a push rod. The adjusting member is threaded to the tool holder and abuts against one end of the push rod, and the other end of the push rod passes through the mounting cavity and abuts against the blade.

[0024] By adopting the above technical solution, the cutting blade can rotate within the cavity, allowing it to be stored when not in use. When the adjusting member is fully against the other end of the push rod, and one end of the push rod passes through the cavity and fully against the cutting blade, the cutting blade is perpendicularly connected to the tool holder, which is the cutting state. When the adjusting member is disengaged from the push rod, one end of the push rod is simultaneously disengaged from the cutting blade, allowing the cutting blade to rotate parallel to the tool holder, thus achieving the storage process.

[0025] Optionally, the cutter bar has a sliding groove on the side of the top rod, and a connector is provided on the top rod. The connector slides in the sliding groove. When the connector slides in the sliding groove and is close to the blade, the blade rotates counterclockwise and is perpendicular to the cutter bar. When the connector slides in the sliding groove and is close to the adjusting member, the blade rotates clockwise and is parallel to the cutter bar.

[0026] By adopting the above technical solution, the opening of the sliding groove allows the top rod to slide into the groove through the connector, thereby enabling the top rod to slide within a limited range, facilitating the adjustment of the adjusting parts to engage or disengage from control, and ensuring smooth process adjustment.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. In use, the tool holder is clamped by an external clamp, and the blade faces the object being cut. During the cutting process, vibration is transmitted to the first and second vibration chambers. The damping oil inside immediately reduces some of the vibration. At the same time, the first and second damping blocks move under the action of the damping oil. The abutment and the first telescopic spring achieve a buffering effect by colliding with each other, and the vibration energy can be absorbed and canceled, thereby eliminating the vibration energy and achieving the effect of vibration reduction. The outer diameter of the first damping block is smaller than the inner diameter of the first vibration chamber, and the outer diameter of the second damping block is smaller than the inner diameter of the second vibration chamber. The fact that both the first and second vibration chambers are circular structures allows the first and second damping blocks to achieve a large amplitude of movement during the movement of the damping oil, thereby reducing the impact of vibration on the machining of the blade and improving the machining accuracy of the blade. It has strong overall practicality and has great market promotion value.

[0029] 2. The transition cavity serves several purposes: first, it facilitates the installation of the abutment block and the first telescopic spring; second, when the first damping block passes through the transition cavity and abuts against the abutment block, the smaller inner diameter of the transition cavity compared to the first vibration cavity allows for greater local pressure of the damping oil within the transition cavity when simultaneously compressed by the first and second damping blocks. This increased local pressure enhances the counterforce on the first and second damping blocks under the elasticity of the first telescopic spring, resulting in better and faster energy dissipation of vibration energy; third, the instantaneous pressure generated locally within the transition cavity effectively pushes the first damping block away from the transition cavity and completely displaces it into the first vibration cavity, thus achieving multi-directional reciprocating vibration damping.

[0030] 3. The damping strip is installed in the T-slot, and the wadding strip abuts against the outer periphery of the second damping block. When the second damping block is moving, the wadding strip can continuously abut against the periphery of the second damping block, quickly decelerating or stopping the second damping strip, and the anti-vibration effect is more obvious.

[0031] 4. The length of the fixed rod is less than the length of the T-slot, so that when the second damping block abuts against the wadding strip, the wadding strip can push the fixed rod to slide back and forth along the T-slot, so that the second damping block can achieve a certain buffering effect during the motion damping process, which is beneficial for process auxiliary damping.

[0032] 5. The prepared mounting cavity allows the blade to rotate within it, enabling it to be stored when not in use. When the adjusting member is fully against the other end of the push rod, one end of the push rod passes through the mounting cavity and is fully against the blade. At this time, the blade and the tool holder are perpendicularly connected, which is the cutting state. When the adjusting member is disengaged from the push rod, one end of the push rod is simultaneously disengaged from the blade. At this time, the blade can rotate to be parallel to the tool holder, thus completing the storage process. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-4 This application provides a detailed description of some embodiments. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those different embodiments or examples.

[0044] Example 1: A metal cutting tool with a vibration damping component, see... Figure 1 and Figure 2It includes a blade head 100 and a blade holder 300. The blade head 100 includes a blade 110 and a blade holder 120. The blade 110 is mounted on the blade holder 120.

[0045] In use, the tool holder 300 is held by an external clamp, with the blade 110 facing the object being cut. The tool shank 120 has a first vibration chamber 130 and a transition chamber 140, located between the first vibration chamber 130 and the second vibration chamber 310. The tool holder 300 has a second vibration chamber 310. The first vibration chamber 130, the transition chamber 140, and the second vibration chamber 310 are interconnected. An oil injection hole 320 is located at the end of the tool holder 300 away from the tool shank 120. Damping oil is injected into the second vibration chamber 310 through the oil injection hole 320. A retaining plug 330 is provided at the oil injection hole 320 to prevent leakage of the damping oil.

[0046] See Figure 2 and Figure 3 A first damping block 131 is disposed in the first vibration chamber 130, and a second damping block 311 is disposed in the second vibration chamber 310. An abutment block 141 and a first telescopic spring 142 are disposed between the first damping block 131 and the second damping block 311. The abutment block 141 and the first telescopic spring 142 are installed in the transition chamber 140. The end of the abutment block 141 away from the first telescopic spring 142 abuts against the first damping block 131, and the end of the first telescopic spring 142 away from the abutment block 141 is connected to the second damping block 311. The abutment block 141 and the first telescopic spring... The abutment block 141, the first telescopic spring 142, and the second damping block 311 are connected in series. When the blade 110 is cutting, the vibration is transmitted to the first vibration chamber 130 and the second vibration chamber 310. The damping oil inside immediately reduces part of the vibration. At the same time, the first damping block 131 and the second damping block 311 move under the action of the damping oil. The abutment part 190 and the first telescopic spring 142 realize the buffering effect of mutual collision. The vibration energy can be absorbed and canceled, thereby eliminating the vibration energy and achieving the effect of vibration reduction.

[0047] The first vibration chamber 130 and the second vibration chamber 310 have circular cross-sections, and the first damping block 131 and the second damping block 311 are cylindrical. The outer diameter of the first damping block 131 is smaller than the inner diameter of the first vibration chamber 130, and the outer diameter of the second damping block 311 is smaller than the inner diameter of the second vibration chamber 310. By utilizing the circular structure of the first vibration chamber 130 and the second vibration chamber 310, the first damping block 131 and the second damping block 311 can achieve a large amplitude movement during the movement of the damping oil, thereby reducing the impact of vibration on the machining of the cutting tool 110 and improving the machining accuracy of the cutting tool 110.

[0048] In some embodiments, the cross-section of the transition cavity 140 is circular, the inner diameter of the transition cavity 140 is smaller than the inner diameter of the first vibration cavity 130, the abutment block 141 and the first telescopic spring 142 are located inside the transition cavity 140, and the first damping block 131 is movably inserted inside the transition cavity 140.

[0049] In some embodiments, the cross-section of the transition cavity 140 is also circular, the inner diameter of the transition cavity 140 is smaller than the inner diameter of the first vibration cavity 130, and the first damping block 131 is movably inserted into the transition cavity 140.

[0050] The transition cavity 140 serves several purposes: first, it facilitates the installation of the abutment block 141 and the first telescopic spring 142; second, when the first damping block 131 passes through the transition cavity 140 and abuts against the abutment block 141, the smaller inner diameter of the transition cavity 140 compared to the first vibration cavity 130 allows for greater local pressure of the damping oil within the transition cavity 140 when simultaneously compressed by the first damping block 131 and the second damping block 311. This increased local pressure enhances the counterforce on the first damping block 131 and the second damping block 311 under the elasticity of the first telescopic spring 142, resulting in better and faster vibration energy cancellation; and third, the instantaneous pressure generated locally within the transition cavity 140 effectively pushes the first damping block 131 out of the transition cavity 140 and completely displaces it into the first vibration cavity 130, thereby achieving multi-directional reciprocating vibration damping.

[0051] In some embodiments, a second telescopic spring 331 is provided at one end of the fixed plug 330 facing the second damping block 311. The second telescopic spring 331 is fixedly connected to the second damping block 311. The second telescopic spring 331 extends into the second vibration chamber 310 and movably abuts against the second damping block 311, so that when the second damping block 311 contacts the second telescopic spring 331, it can achieve a reverse damping effect, and with the cooperation of the first telescopic spring 142, it can realize the process of successively damping the left and right movements.

[0052] In some embodiments, the handle 300 is provided with a T-shaped groove 340 on the inner wall of the second vibration chamber 310. There are two T-shaped grooves 340, which are respectively arranged opposite to each other. A damping strip 350 is slidably connected in the T-shaped groove 340. The damping strip 350 includes a fixed rod 351 and several frayed strips 352. The frayed strips 352 are connected to the fixed rod 351 and face the second vibration chamber 310. The fixed rod 351 is slidably connected in the T-shaped groove 340. The frayed strips 352 abut against the periphery of the second damping block 311. When the second damping block 311 is moving, the frayed strips 352 can continuously abut against the periphery of the second damping block 311, so as to quickly decelerate or stop the second damping strip 350, and the vibration reduction effect is more obvious.

[0053] It should be noted that in this embodiment, the damping strip 350 is made of rubber, and the wavy strip 352 is integrally formed with the fixing rod 351. During the sliding process of the T-groove 340, it will not generate a fast movement speed and has a certain friction force, which is convenient for assisting in shock absorption. At the same time, the wavy strip 352 abuts against the second damping block 311, which also has a certain friction force and a certain degree of softness, thus achieving a better shock absorption effect. The wavy strip 352 and the fixing rod 351 are integrally formed, and the overall structure is stable and not easy to break.

[0054] In this embodiment, the length of the fixed rod 351 is less than the length of the T-groove 340. When the second damping block 311 abuts against the wavy strip 352, the fixed rod 351 slides along the T-groove 340, so that when the second damping block 311 abuts against the wavy strip 352, the wavy strip 352 can push the fixed rod 351 to slide back and forth along the T-groove 340, so that the second damping block 311 can achieve a certain buffering effect during the motion damping process, which is beneficial for process-assisted damping.

[0055] In some embodiments, a cooling chamber 150 is provided above the first vibration chamber 130 on the tool holder 120. The cooling chamber 150 is connected to both the first vibration chamber 130 and the second vibration chamber 310. With the help of the cooling chamber 150, the damping oil is prone to heat up after a long time during the shaking process. When it overflows into the cooling chamber 150, the surface temperature of the damping oil can be effectively reduced by utilizing the area of ​​the cooling chamber 150, thereby improving the service life of the tool.

[0056] In some embodiments, a sealing ring 160 is provided at the end of the tool holder 120 facing the tool handle 300, so that the damping oil is not easy to leak out from the connection between the tool holder 120 and the tool handle 300. The tool holder 120 is inserted into the tool handle 300 by a plug-in type. The tool holder 120 and the tool handle 300 are connected by a fastener 170. The fastener 170 is a fastening bolt. There are two fastening bolts, which pass through the handle in sequence and are connected to the tool holder 120.

[0057] See Figure 2 and Figure 4 The blade 110 is installed at the end of the tool holder 120 away from the handle 300. The tool holder 120 has a mounting cavity 180, which is L-shaped. The blade 110 is located in the mounting cavity 180 and is hinged to the tool holder 120. The blade 110 is also L-shaped, with the short side being the hinge point. The tool holder 120 has an abutment 190 on the side of the blade 110. The abutment 190 includes an adjusting member 191 and a push rod 192. The adjusting member 191 is an internal hexagonal fastening bolt. The hexagonal fastening bolt is threaded to the tool holder 120 and abuts against one end of the push rod 192. The push rod 192 slides horizontally in the tool holder 120, and the other end of the push rod 192 passes through the mounting cavity 180 and movably abuts against the blade 110.

[0058] The prepared mounting cavity 180 allows the blade 110 to rotate within it, enabling it to be stored when not in use. When the adjusting member 191 is fully abutting the other end of the push rod 192, and one end of the push rod 192 passes through the mounting cavity 180 and fully abuts the blade 110, the blade 110 is perpendicularly connected to the tool holder 120, which is the cutting state. When the adjusting member 191 disengages from the push rod 192, one end of the push rod 192 disengages from the blade 110, and the blade 110 loses its support and can rotate to be parallel to the tool holder 120, thus achieving the storage process.

[0059] Specifically, the cutter bar 120 has a sliding groove 200 on the side of the push rod 192. The push rod 192 is provided with a connector 193. The connector 193 and the push rod 192 have a T-shaped structure. The connector 193 slides in the sliding groove 200. When the connector 193 slides in the sliding groove 200 and is close to the blade 110, the push rod 192 abuts against the blade 110. The blade 110 rotates counterclockwise and is perpendicular to the cutter bar 120. When the connector 193 slides in the sliding groove 200 and is close to the adjusting member 191, the push rod 192 disengages from the blade 110. The blade 110 can rotate clockwise and is parallel to the cutter bar 120, realizing the storage process. By utilizing the sliding groove 200, the push rod 192 can slide in the sliding groove 200 through the connector 193, thereby realizing the sliding of the push rod 192 within a limited range, which facilitates the adjustment member 191 to abut or disengage, and the process adjustment is smooth.

[0060] The implementation principle of this application embodiment is as follows: In use, the tool holder 300 is clamped by an external clamp, and the blade 110 faces the object being cut. When the blade 110 is cutting, the vibration is transmitted to the first vibration chamber 130 and the second vibration chamber 310. The damping oil inside immediately reduces part of the vibration. At the same time, the first damping block 131 and the second damping block 311 move under the action of the damping oil. The abutment 190 and the first telescopic spring 142 realize the buffering effect of mutual collision, and the vibration energy can be absorbed and canceled, thereby eliminating the vibration energy and achieving the effect of vibration reduction. The outer diameter of the first damping block 131 is smaller than the inner diameter of the first vibration chamber 130, and the outer diameter of the second damping block 311 is smaller than the inner diameter of the second vibration chamber 310. Since the first vibration chamber 130 and the second vibration chamber 310 are both circular structures, the first damping block 131 and the second damping block 311 can achieve a large amplitude movement during the movement of the damping oil, thereby reducing the impact of the vibration on the processing of the blade 110 and improving the processing accuracy of the blade 110.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
