Technical Field
[0001] The utility model relates to the technical field of Swiss-type lathes, and more particularly to a tool holder mechanism for Swiss-type lathes. Background Art
[0002] Swiss-type CNC lathe, also known as Swiss-type CNC lathe, is a high-precision and high-efficiency CNC machine tool. In mobile phone manufacturing, Swiss-type CNC lathes can process extremely fine connectors, camera components, etc.; in the medical field, they can produce high-precision micro-medical device parts. The continuous development and innovation of Swiss-type CNC lathes have enabled them to play an increasingly important role in modern manufacturing and have made important contributions to improving product quality and production efficiency.
[0003] At present, when processing precision micro-shaft parts, the dual-spindle structure and high-precision tool system of the Swiss-type lathe can ensure the dimensional accuracy and surface quality of the parts; and when processing parts with complex shapes, the rich tool arrangement and flexible processing methods can give full play to its advantages.
[0004] However, the processing speed of a Swiss-type lathe is usually fast, and the tool will generate a large impact force when moving and cutting quickly. The impact force may cause the tool to have a slight displacement or vibration during the cutting process, thereby affecting the accuracy of the processing size and surface roughness. For this reason, a tool holder mechanism for a Swiss-type lathe is proposed to improve the existing problems. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0029] See also Figure 1-4 , the utility model provides the following technical solutions:
[0030] Example 1
[0031] See Figure 1A tool holder mechanism for a Swiss-type lathe comprises a fixed component 1, a slider component 3 is mounted on the fixed component 1, and a tool holder component 2 is mounted on the slider component 3.
[0032] See Figure 1 and Figure 2 The tool holder assembly 2 includes a tool holder 22, which is configured as a rectangular structure. A tool body 21 is provided on one side of the tool holder 22, a motor 23 is installed in the middle of the tool holder 22, and a slider 27 is installed below the motor 23 and connected to the tool holder 22. A group of mounting blocks 25 are respectively installed on both sides of the slider 27. The two groups of mounting blocks 25 are symmetrically arranged on both sides of the tool holder to ensure that the forces on both sides of the tool holder 22 are balanced. A bolt 26 is provided through the mounting block 25. A spring 24 is provided on the outer side of the bolt 26 near the tool holder 22. The end of the bolt 26 away from the spring 24 is provided through the tool holder 22. The spring 24 can absorb and buffer the impact force generated during the processing of the tool body 21, thereby reducing vibration and damage to the tool body 21, the tool holder 22 and the entire machine tool structure.
[0033] See Figure 1 and Figure 4 , a slide bar 32 is installed at the bottom of the slider 27, and the shape of the slide bar 32 is adapted to the shape of the slider 27. The slider 27 is slidably installed above the slide bar 32. In actual application, the motor 23 provides power for the operation of the cutter body 21, so that the cutter body 21 can process the material. When the cutter body 21 processes the material, due to the high-speed operation, the cutter body 21 will generate an impact force on the tool holder 22. The tool holder 22 will move due to the impact force, and the slider 27 connected to the tool holder 22 will slide along the slide bar 32. The matching setting of the slide bar 32 and the slider 27 can ensure that the cutter body 21 moves along a precise straight line trajectory, thereby ensuring the precision and accuracy of the processing, and then squeezing the spring 24. The existence of the spring 24 increases the flexibility and adaptability of the tool holder system, reduces the risk of failure due to rigid collision or excessive stress, and improves the reliability and service life of the entire tool holder system.
[0034] See Figure 1 and Figure 2 A slider seat 31 is installed under the slide bar 32, and a slider groove 33 is opened on the side of the slider seat 31 close to the slide bar 32. The shape of the slider groove 33 is fixedly connected to the slide bar 32. The fixed installation of the slide bar 32 allows the slider 27 to slide relatively on the slide bar 32, which can ensure that the cutter body 21 moves along a precise straight line trajectory, thereby ensuring the precision and accuracy of the processing.
[0035] See Figure 2 and Figure 3 The fixing assembly 1 includes a fixing seat 14 , a fixing plate 11 is installed above the fixing seat 14 , and a fixing plate 11 is provided at one end of the fixing seat 14 away from the tool holder 22 .
[0036] See Figure 1 A mounting seat 12 is installed on the side wall of the fixed plate 11. The mounting seat 12 is cylindrical in shape. A workpiece 13 is installed on the end of the mounting seat 12 away from the fixed plate 11. The workpiece 13 is arranged facing the cutter body 21, which facilitates the precise processing of the workpiece 13 by the cutter body 21 in actual applications.
[0037] See Figure 1 and Figure 3 The fixed seat 14 is set to a stepped structure, the upper step of the fixed seat 14 is provided with a fixed plate 11, and the lower step of the fixed seat 14 is provided with a second fixed block 16. The second fixed block 16 is provided with a first fixed block 15 at one end close to the fixed plate 11. A detachable device is installed on the first fixed block 15 to facilitate the replacement of the tool. The second fixed block 16 provides support for the entire device. The first fixed block 15 and the second fixed block 16 bear the cutting force, feed force and other forces generated by the cutter body 21 during the processing of the workpiece 13, provide stable support for the tool, prevent the tool from deflecting or deforming, and ensure the stable operation of the device.
[0038] Specifically, in actual applications, the motor 23 provides power for the operation of the cutter body 21 to enable the cutter body 21 to process the material. When the cutter body 21 processes the material, due to the high-speed operation, the cutter body 21 will generate an impact force on the cutter holder 22. The cutter holder 22 will move due to the influence of the impact force, and the slider 27 connected to the cutter holder 21 will slide along the slide bar 32, thereby squeezing the spring 24. The presence of the spring 24 increases the flexibility and adaptability of the cutter holder system.
[0039] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
