The technical problem to be solved by the utility model is to provide a rotatable CNC tool holder with adjustable tool angle.

[0004] The rotatable and positionable CNC tool holder in the above patent has the following shortcomings: the tool holder needs to be rotated and adjusted by cooperating with multiple sets of bolts and the clamping connection of the limiting plane, which is not only time-consuming and labor-intensive, but also increases costs. The overall convenience of use is also low, and the installation of multiple parts is not convenient for disassembly, and the overall use effect is low. At the same time, the fixing of the bolts is relatively rigid, and the vibration generated by the tool during use can easily wear the tool holder and the tool, reducing the overall service life.

[0005] Therefore, we propose a rotatable CNC tool holder to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0031] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0032] A rotatable CNC tool holder provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Embodiment 1

[0033] Combination Figure 1-Figure 3 As shown, the utility model provides a rotatable CNC tool holder.

[0034] Specifically, it includes an annular knife seat shell 1 and a knife 2. The outer side surface of the knife 2 is sleeved with an adjusting sleeve handle 3 near the side of the annular knife seat shell 1. One end of the adjusting sleeve handle 3 is located inside the annular knife seat shell 1 and is connected to an embedded mounting plate 6. The outer side surface of the embedded mounting plate 6 is located inside the annular knife seat shell 1 and is sleeved with a supporting sleeve plate 13. An arc guide piece 14 is embedded and installed on the inner left side wall of the annular knife seat shell 1. The arc guide piece 14 is mainly used to facilitate the rolling of a card receiving ball 15. A plurality of groups of card receiving balls 15 are arranged on the surface of the left end of the supporting sleeve plate 13 near the surface of the arc guide piece 14. A plurality of groups of card receiving balls 15 are arranged in an annular manner on the outer surface of the embedded mounting plate 6 near the plurality of groups of card receiving balls 15. A plurality of groups of supporting bottom blocks 8 are annularly installed on the inner right side end of the annular knife seat shell 1. The left ends of the plurality of supporting bottom blocks 8 are all clamped with extrusion struts 9. A spring 10 is sleeved on the outer side of the extrusion struts 9. A support column 12 is arranged between the left end of the extrusion strut 9 and the right end of the supporting sleeve plate 13. The left end of the mounting plate 6 is threadedly embedded with a threaded locking column 7, and the right end of the supporting column 12 is provided with a telescopic slide groove 11. The telescopic slide groove 11 is mainly used to facilitate the telescopic movement of the extrusion support rod 9 and to limit the position. The left end of the extrusion support rod 9 is slidably connected to the inner side of the telescopic slide groove 11, and the left end of the supporting column 12 is connected to the right end of the supporting sleeve plate 13. The two end surfaces of the spring 10 are respectively abutted against the outer end surfaces of the supporting column 12 and the supporting bottom block 8, and the outer side surface of the supporting sleeve plate 13 slides against the inner side surface of the annular tool holder shell 1, and multiple groups of card receiving balls 15 are respectively clamped in the multiple groups of card slots 17. The use of the above-mentioned components, especially the adjustment sleeve 3 drives the embedded mounting plate 6, and the supporting bottom block 8, the spring 10 and the reaction of each component to squeeze the supporting sleeve plate 13, makes multiple card receiving balls 15 and multiple card slots 17 respectively adjust the position and clamp, and quickly completes the regulation of the tool 2, which not only saves time and effort, saves cost, but also improves the convenience of overall use. Embodiment 2

[0035] Combination Figure 1 and Figure 2 As shown, based on the first embodiment,

[0036] Specifically, the right end of the threaded locking column 7 is connected to the locking plate 5 located at the right end of the annular tool holder shell 1. Through the adjustment of the locking plate 5, the threaded locking column 7 is rotated and separated from the embedded mounting plate 6, which facilitates the separation of the tool 2 from the annular tool holder shell 1 and improves the convenience of disassembly and assembly. Embodiment 3

[0037] Combination Figure 2 and Figure 3 As shown, in the above embodiment,

[0038] Specifically, a protective hollow rubber ring 16 is sleeved on the outer side of the clamping ball 15. The protective hollow rubber ring 16 and the spring 10 in the first embodiment cooperate with the vibration reduction of each component, so that the wear between the tool 2 and the various mounting components of the annular tool holder housing 1 is reduced, and the overall durability is improved.

[0039] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0040] Specifically, a mounting plate 4 is sleeved on the right outer side surface of the annular tool holder housing 1. The mounting plate 4 is mainly used to facilitate the installation and connection between the annular tool holder housing 1 and the installation location of the numerical control equipment.

[0041] The working principle and use process of the utility model are as follows: first, when in use, the user first drives the threaded locking column 7 and the embedded mounting plate 6 to loosen through the locking plate 5, and then adjusts the adjusting sleeve 3 to drive the embedded mounting plate 6 to rotate, so that the clamping ball 15 slides through the arc guide 14 to squeeze the support sleeve 13, and the spring 10 outside the squeezing strut 9 between the supporting bottom block 8 and the supporting column 12 reacts to squeeze the support sleeve 13, so that multiple clamping balls 15 and multiple clamping grooves 17 are respectively adjusted and clamped, and the tool 2 is quickly rotated. This not only saves time, labor and cost, but also improves the convenience of overall use. Secondly, when in use, the threaded locking column 7 is directly rotated and separated from the embedded mounting plate 6 through the locking plate 5, and the adjusting sleeve handle 3 can drive the tool 2 as a whole to move out of the annular tool holder shell 1. The operation is performed in reverse during installation. This not only improves the convenience of disassembly and assembly, but also improves the overall use effect. Finally, when in use, after the tool 2 is fixed and installed through the embedded mounting plate 6 by various components, when the tool 2 vibrates during use, the elastic protective effect of the protective hollow rubber ring 16 on the outside of the clamping ball 15, including the spring 10 and the vibration reduction structure of various components, reduces the wear between the components and improves the overall durability.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
