Description

Technical Field

[0001] The utility model belongs to the field of parts processing, and specifically relates to a vibration-damping tool bar for a numerically controlled lathe. Background Art

[0002] In the field of CNC lathe processing, improving processing accuracy and efficiency and extending tool life are always the key goals to pursue. Faced with complex and precise processing tasks, high-frequency vibration has become a major factor restricting processing quality and efficiency. At present, in the processing and production process, slender shell parts with an aspect ratio of more than 5 and thin walls are often encountered. During the inner cavity processing, due to the excessive length of the tool bar, vibration will occur during the processing. The larger the aspect ratio, the thinner the wall, and the more serious the vibration. As a result, the dimensional accuracy and roughness of the parts cannot meet the user's requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a vibration-damping tool bar for a CNC lathe, thereby solving the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0005] A vibration-damping tool bar for a CNC lathe comprises: a tool bar; a groove is provided on one side of the tool bar, and the cavity in the groove is an oil storage cavity; a vibration-damping structure is provided in the oil storage cavity, and the vibration of the tool bar can be balanced by vibration reduction; the vibration-damping structure comprises a resonant rod, and one end of the resonant rod is slidably connected in the oil storage cavity through the groove, an oil hole is provided on one side of the top of the tool bar, and the oil hole is communicated with the oil storage cavity, and an oil plug is installed in the oil hole.

[0006] Optionally, the resonance rod is a T-shaped structure, one end of the resonance rod abuts against the outer wall of the groove, and a tool holder is installed at one end of the tool rod, and the tool holder is located on a side close to the resonance rod.

[0007] Optionally, sealing rings are provided between the resonance rod and the groove and between the oil plug and the oil hole.

[0008] Optionally, a resonance cavity is provided in the resonance rod on one side close to the tool holder.

[0009] Optionally, a configuration block is installed at one end of the tool rod away from the tool holder.

[0010] Optionally, a tool platform is installed at the outer bottom of the tool rod, and the tool platform is located between the tool holder and the configuration block. Threaded holes are opened on both sides of the bottom of the tool platform, and a fixing bolt is threadedly connected in each threaded hole.

[0011] Optionally, a tool platform pressure cover is installed on the outer top of the tool rod, and the tool platform pressure cover is fixedly connected to the tool platform by bolts.

[0012] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0013] By setting up a shock-absorbing structure and cooperating with the resonant rod in the shock-absorbing structure and the oil storage chamber, the vibration of the tool rod during the machining process can be reduced. The resonant rod acts as a kinetic energy converter, which can absorb part of the vibration energy when encountering vibration, and convert this part of energy into other forms so that it is dissipated in the fluid inside the oil storage chamber. The oil storage chamber acts as a buffer storage device for impact energy, and absorbs and disperses the vibration energy transmitted through the resonant rod through the flow and compression of the internal oil, thereby reducing the vibration energy feedback to the tool rod and the workpiece, and can reduce the damage to the machine tool spindle during the machining process, while playing a role in protecting the machining equipment.

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model will now be described in further detail with reference to the accompanying drawings.

[0023] See also Figure 1-3 As shown, in this embodiment, a vibration-damping tool rod for CNC lathe is provided, including a tool rod 5; a groove is provided on one side of the tool rod 5, and the cavity in the groove is an oil storage chamber 9; wherein a vibration-damping structure is provided in the oil storage chamber 9, and the vibration of the tool rod 5 can be balanced by vibration reduction; the vibration-damping structure includes a resonant rod 4, and one end of the resonant rod 4 is slidably connected in the oil storage chamber 9 through the groove, an oil hole is provided on one side of the top of the tool rod 5, and the oil hole is connected to the oil storage chamber 9, and an oil plug 2 is installed in the oil hole.

[0024] It should be noted that by designing the oil storage chamber 9 and the vibration reduction structure inside the tool bar 5, the vibration during the processing is effectively reduced, thereby improving the processing accuracy and surface quality, and extending the service life of the tool bar 5. The vibration reduction structure set in the oil storage chamber 9 is mainly the resonance rod 4. The resonance rod 4 is installed in the tool bar 5 through a groove in the oil storage chamber 9, allowing the resonance rod 4 to vibrate slightly relative to the tool bar 5. When the tool bar 5 encounters external vibration during the processing, the resonance rod 4 can absorb or dissipate part of the vibration energy through its own vibration, thereby reducing the overall vibration of the tool bar 5. The oil storage chamber 9 not only serves as a storage space for the vibration reduction structure, but also can realize the storage and supply of engine oil by connecting with the oil hole. An oil plug 2 is installed in the oil hole to control the inflow of engine oil and protect the engine oil in the oil storage chamber from being contaminated by the outside world, while preventing oil leakage and foreign objects from entering the oil storage chamber 9.

[0025] In an embodiment of the utility model, the resonance rod 4 is a T-shaped structure, one end of the resonance rod 4 is in contact with the outer wall of the groove, a tool holder 1 is installed at one end of the tool rod 5, and the tool holder 1 is located on the side close to the resonance rod 4, sealing rings 3 are provided between the resonance rod 4 and the groove and between the oil plug 2 and the oil hole, and a resonance cavity is opened on the side of the resonance rod 4 close to the tool holder 1.

[0026] It should be noted that the resonance rod 4 with a T-shaped structure is one of the key components of the design. One end of the T-shaped structure abuts against the outer wall of the groove, and the other end is suspended in the oil storage chamber 9. It is a cantilever mechanism that can withstand vertical downward loads and lateral forces, which helps to effectively transmit and absorb vibrations during processing and reduce adverse effects during processing. The tool holder 1 installed at one end of the tool rod 5 is located on the side close to the resonance rod 4. When the tool holder 1 is connected to the tool rod 5, the tool holder 1 can press the resonance rod 4 into the groove. A sealing ring 3 is provided between the resonance rod 4 and the groove, and between the oil plug 2 and the oil hole. The sealing ring 3 ensures the sealing performance of the liquid medium (such as engine oil), prevents leakage and contamination, and ensures the integrity and functionality of the shock absorbing system. A resonance cavity is opened on the side of the resonance rod 4 close to the tool holder 1. The resonance cavity can further optimize the vibration absorption effect, improve the vibration effect of the resonance rod 4, and reduce the additional vibration generated during work through the resonance principle, thereby improving the processing efficiency.

[0027] In the embodiment of the present utility model, a configuration block 8 is installed at one end of the tool rod 5 away from the tool holder 1 .

[0028] It should be noted that the main function of the configuration block 8 is to balance the weight of the overhanging portion at the front of the tool bar 5. During the processing operation, the tool bar 5 may bend or deform due to its own weight and various forces acting on it (such as cutting force). The configuration block 8 helps to offset this tendency by adding weight or support force in the opposite direction, thereby maintaining the stability of the tool bar 5. By balancing the weight of the overhanging portion, the configuration block 8 reduces the force transmitted to the tool holder 1 itself. It effectively avoids or reduces excessive burden on the transmission mechanism of the tool holder 1, thereby reducing the risk of damage and extending the life of the equipment.

[0029] In an embodiment of the utility model, a tool platform 6 is installed at the outer bottom of the tool rod 5, and the tool platform 6 is located between the tool holder 1 and the configuration block 8. Threaded holes are provided on both sides of the bottom of the tool platform 6, and a fixing bolt 10 is threadedly connected in each threaded hole. A tool platform pressure cover 7 is installed at the outer top of the tool rod 5, and the tool platform pressure cover 7 is fixedly connected to the tool platform 6 by bolts.

[0030] It should be noted that the tool holder 6 is a key component of the machining system, and its main function is to install and fix the tool bar 5. The tool holder 6 ensures the stability of the tool during the machining process, thereby ensuring the machining quality and precision. A tool holder cover 7 is installed on the top of the outer side of the tool bar 5. The main function of the tool holder cover 7 is to further ensure the fixation and stability of the tool during the machining process. By connecting with the tool holder 6, the tool holder cover 7 presses and locks the tool to prevent the tool from being displaced during high-speed rotation or violent movement. The use of bolts makes the connection between the tool holder 6 and the tool holder cover 7 both strong and adjustable as needed. It makes tool changing and tool adjustment quick and easy, greatly improving the efficiency and flexibility of machining operations.

[0031] The working principle of the vibration-damping tool bar for CNC vehicles provided by the utility model is as follows: first, the various parts are processed according to the parts drawings, and the assembly begins after the parts are inspected and qualified; first, the resonant rod 4 is installed into the tool bar 5, and then the tool holder 1 is installed, and the resonant rod 4 is pressed firmly at the same time, and the engine oil is injected into the oil storage chamber 9 through the oil hole. After the engine oil is filled, the oil hole is closed with the oil plug 2 and the sealing ring 3, and the assembly is completed.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention.
