DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-7As shown, the utility model is a vibration-resistant turning tool structure for machining, including a tool bar 1. When the existing turning tool structure performs turning processing, especially when performing in-hole processing on deep holes, since the tool bar 1 is relatively long, the turning tool contacts the workpiece and is prone to vibration, causing the turning tool to slightly displace, reducing the processing accuracy of the workpiece, resulting in unqualified processed workpieces, reducing the yield rate of the workpiece, and being inconvenient to use.

[0038] The vibration-resistant turning tool structure for machining described in the utility model further comprises a tool head component 2 and a damping vibration-resistant component 3 .

[0039] The knife bar 1 is provided with a hollow chamber 11 extending along the length direction.

[0040] The cutter head assembly 2 extends along the length direction of the cutter bar 1, with one end extending into the hollow chamber 11 and the other end being arranged outside the hollow chamber 11 for turning processing;

[0041] The damping and anti-vibration component 3 is disposed in the hollow chamber 11 and sleeved on one end of the cutter head component 2 .

[0042] In the above scheme, a damping anti-vibration component 3 is arranged on one end of the cutter head component 2 extending into the hollow chamber 11, which can dissipate energy, reduce vibration, and further reduce the vibration transmitted to the tool rod 1, avoiding the tool vibration phenomenon, which is beneficial to improving the processing accuracy.

[0043] Specifically, the hollow chamber 11 is extended along the length direction of the tool bar 1, and the cutter head assembly 2 is extended along the length direction of the tool bar 1 by a certain length. The other end of the cutter head assembly 2 is protruded from the hollow chamber 11, and the protruding part is used for turning processing; and the damping anti-vibration assembly 3 is arranged on one end of the cutter head assembly 2 located in the hollow chamber 11.

[0044] Preferably, the damping anti-vibration component 3 is injected with shock-absorbing oil to reduce vibration.

[0045] When the turning tool is turning the workpiece, the other end of the tool head assembly 2 is in contact with the workpiece. If the tool head assembly 2 vibrates, the vibration is transmitted from the tool head assembly 2 to the damping anti-vibration assembly 3. The damping oil of the damping anti-vibration assembly 3 reduces the up and down shaking, which can consume the energy and reduce the vibration, thereby reducing the vibration energy transmitted to the tool rod 1, reducing the vibration of the tool rod 1 caused by its own excessive length, avoiding the vibration of the turning tool and damaging the workpiece, which is beneficial to improving the processing progress and facilitating use.

[0046] The damping and anti-vibration component 3 is extended along the length direction of the tool rod 1 and has two ends clamped on the tool head component 2 .

[0047] Specifically, the extension direction of the damping and anti-vibration component 3 is the same as the extension direction of the cutter head assembly 2. When the vibration is transmitted from the cutter head assembly 2 to the damping and anti-vibration component 3, the vibration energy is directly consumed near the cutter head assembly 2, thereby reducing the energy transmitted to the tool rod 1, reducing the vibration of the tool rod 1, and facilitating use.

[0048] like Figure 1 and Figure 2 As shown, the hollow chamber 11 , the cutter head assembly 2 and the damping and anti-vibration assembly 3 are all arranged along the center line of the cutter rod 1 .

[0050] Preferably, the tool bar 1, the hollow chamber 11, the tool head assembly 2 and the damping anti-vibration assembly 3 are coaxially arranged. The coaxial arrangement of multiple components on the turning tool structure is convenient for the user to install and adjust the turning tool to align with the workpiece, which is beneficial to improving the accuracy of the turning tool and facilitating use. The outer wall of one end of the tool head assembly 2 abuts against the peripheral wall of the hollow chamber 11, reducing the gap between the outer side of the tool head assembly 2 and the peripheral wall of the hollow chamber 11, avoiding vibration caused by loose installation between the tool head assembly 2 and the tool bar 1, which is beneficial to reducing vibration and facilitating use.

[0051] like Figure 2 As shown, the cutter head assembly 2 includes:

[0052] Cutting head 21;

[0053] A knife seat 22, one end of which extends into the hollow chamber 11, and the other end of which protrudes out of the hollow chamber 11 and is connected to one end of the knife head 21;

[0059] The two ends of the damping and anti-vibration component 3 are sandwiched between the knife seat 22 and the base 24. The inner diameter of the damping and anti-vibration component 3 is smaller than the outer diameters of the knife seat 22 and the base 24.

[0060] The outer peripheral wall of the base 24 abuts against the peripheral wall of the hollow chamber 11 .

[0061] Preferably, the outer diameters of the damping and anti-vibration assembly 3, the knife seat 22 and the base 24 are the same. The outer peripheral walls of the damping and anti-vibration assembly 3, the knife seat 22 and the base 24 are against the peripheral wall of the hollow chamber 11, which is conducive to reducing the gap between the damping and anti-vibration assembly 3, the knife seat 22 and the base 24 and the hollow chamber 11, and is conducive to the stable installation of the damping and anti-vibration assembly 3, the knife seat 22 and the base 24 in the hollow chamber 11, avoiding collision with the peripheral wall of the hollow chamber 11, and is conducive to reducing vibration and facilitating use.

[0062] Preferably, the knife seat 22 and the base 24 are both arranged in a columnar shape. Preferably, they can be arranged in a cylindrical shape, and the whole is similar to being formed by stacking a plurality of cylinders.

[0068] In the above scheme, the cutter head 21 and the cutter seat 22 are provided with two matching corrugated grooves 27. The two corrugated grooves 27 match each other, which can increase the friction between the cutter head 21 and the cutter seat 22, enhance the connection stability between the cutter head 21 and the cutter seat 22, avoid relative movement between the cutter head 21 and the cutter seat 22, and help reduce the vibration of the turning tool for easy use.

[0069] Specifically, the other end of the tool holder 22 away from the damping anti-vibration component 3 protrudes from the hollow chamber 11 and is provided with a corrugated groove 27 at the end. The end of the tool head 21 close to the tool holder 22 is also provided with a corrugated groove 27. The two corrugated grooves 27 are staggered and matched, which can increase the friction force at the connection between the tool head 21 and the tool holder 22 and stabilize the connection.

[0070] like Figure 4 As shown, preferably, the cutter head 21 and the cutter seat 22 are connected in the length direction of the cutter rod 1 by a plurality of screws 28 arranged at intervals.

[0071] A plurality of screws 28 connect the cutter head 21 and the cutter seat 22, and are used in conjunction with two matching corrugated grooves 27, so that the cutter head 21 and the cutter seat 22 are firmly connected and do not move relative to each other, which is beneficial to reducing the vibration of the turning tool structure.

[0072] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, both ends of the connecting rod 23 are detachably connected to the knife seat 22 and the base 24 respectively.

[0073] In the above scheme, the two ends of the connecting rod 23 are detachably connected to the tool holder 22 and the base 24 respectively, so that the tool head assembly 2 can be disassembled and assembled, which is convenient for the assembly of the tool head assembly 2 and the damping and anti-vibration assembly 3, and also convenient for the standardized assembly and assembly of various components, assembly line operation, and easy use.

[0074] Specifically, both ends of the connecting rod 23 are provided with external threads, which are respectively threadedly connected to the tool holder 22 and the base 24. In addition, the connection mode between the tool holder 22 and the base 24 and the connecting rod 23 can also be set to a clamping mode, etc., which is not limited here.

[0077] The coolant can flow from the delivery cavity 111 into the cutter head assembly 2 to flush, cool and lubricate the cutter head 21, thereby facilitating the continuous operation of the turning tool structure.

[0078] An internal thread is disposed on a peripheral wall of one end of the conveying cavity 111 away from the installation cavity 112 .

[0079] The two ends of the connecting rod 23 are hollow, and the other end of the connecting rod 23 is connected to the conveying cavity 111. The tool holder 22 is provided with a water outlet groove 221 connected to one end of the connecting rod 23 for guiding the coolant in the conveying cavity 111 to the tool head 21.

[0080] Specifically, the coolant flows through the delivery cavity 111 and the middle part of the connecting rod 23 in sequence, enters the tool holder 22 , and flows toward the tool head 21 through the water outlet groove 221 on the tool holder 22 .

[0081] Preferably, the water outlet channel of the water outlet groove 221 is extended along the length direction of the knife rod 1 , and the water outlet of the water outlet channel is arranged toward the knife head 21 .
