[0029] 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 in 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.

[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a CNC core-moving machine tool holder with high processing accuracy, including a core-moving machine body 1, through which a workpiece is processed, a tool holder body 2 can be installed and removed on the core-moving machine body 1 through an adjustment component 3, and the tool holder body 2 supports and fixes multiple groups of tools, and a fixing component 4 is arranged on the fixed tool holder body 2, and the fixing component 4 improves the fixing effect of the tool.

[0031] Reference Figure 2 and Figure 3 The adjustment component 3 includes a mounting plate 31, on which a plurality of threaded holes are provided, and a positioning block is provided on the left side of the mounting plate 31 for mounting the mounting plate 31 on the core-walking machine body 1, and a T-slot 36 is provided on the right side of the mounting plate 31, and a T-block 37 is fixedly connected to the left side of the tool holder body 2, which limits the tool holder body 2 through the T-slot 36 and the T-block 37, and a cylindrical rod 35 is fixedly connected to the left end of the front side of the tool holder body 2, and the tool holder body 2 is driven to move vertically through the moving effect of the cylindrical rod 35, and the outer circumference of the cylindrical rod 35 is rotatably connected to the hinged rod 33, and the cylindrical rod 35 is driven to move through the moving effect of the hinged rod 33, and the bottom end of the hinged rod 33 is hinged with a movable ring 34, and the movable ring 34 is driven to move.

[0032] Reference Figure 3 and Figure 4 The fixing component 4 includes a pressing plate 41. The pressing surface of the pressing plate 41 is a rubber surface with a certain elastic deformation effect, which improves the pressing and fixing effect on the tool. The front of the pressing plate 41 is fixedly connected with a ring 44. The fixing effect of the ring 44 prevents the ring 44 from falling off. The inner wall of the ring 44 is rotatably connected with a rotating block 45. The moving effect of the rotating block 45 drives the pressing plate 41 to move. The front of the rotating block 45 is fixedly connected with a bolt 42.

[0033] Reference Figure 2 and Figure 3 The inner wall of the movable ring 34 is threadedly connected with a threaded rod 32, and the left end of the threaded rod 32 is rotatably connected to the right inner wall of the mounting plate 31. The rotating effect of the threaded rod 32 drives the movable ring 34 to move laterally. The outer periphery of the T-block 37 is slidably connected to the inner wall of the T-slot 36. The sliding effect of the T-block 37 guides the tool holder body 2 to prevent the tool holder body 2 from shifting when moving. The outer diameter of the T-block 37 is smaller than the inner diameter of the T-slot 36. Since there is a certain gap between the T-block 37 and the T-slot 36, the tool holder body 2 can be allowed to move within a certain range.

[0034] Reference Figure 4 A guide rod 43 is fixedly connected to the front of the pressure plate 41, and the fixing effect of the guide rod 43 prevents the guide rod 43 from falling off. The outer periphery of the guide rod 43 is slidably connected to the inner wall of the tool holder body 2, and the guide rod 43 guides the pressure plate 41 to prevent the pressure plate 41 from deflecting when moving.

[0035] Reference Figure 3 and Figure 4 The shape of the pressure plate 41 is arc-shaped. Since the pressure plate 41 is arc-shaped, the contact area between the pressure plate 41 and the tool is increased, and the clamping and fixing effect on the tool is further improved. The outer periphery of the bolt 42 penetrates the inner wall of the right end of the front side of the tool holder body 2 and is threadedly connected. By rotating the bolt 42, the rotating block 45 is driven to rotate and move at the same time. Two groups of pressure plates 41 are provided, and the two groups of pressure plates 41 are symmetrically distributed. By providing two groups of pressure plates 41, the two groups of tools can be fixed and installed.

[0036] Working principle: When the staff needs to install the tool on the tool holder body 2, the staff inserts the tool into the top inner wall of the tool holder body 2 and rotates the bolt 42 at the same time. The bolt 42 drives the pressure plate 41 to move, so that the pressure plate 41 presses and fixes the tool. At this time, the installation of the tool is completed.

[0037] Since the insertion depth of the tool during installation deviates to a certain extent from the standard positioning height, the staff rotates the threaded rod 32 so that the threaded rod 32 drives the movable ring 34 to move laterally, thereby causing the movable ring 34 to drive the hinged rod 33 to move, and the hinged rod 33 drives the cylindrical rod 35 to move vertically, so that the tool holder body 2 moves vertically to adjust the cutting height of the tool installed on the tool holder body 2.

[0038] When the tool on the tool holder body 2 needs to be disassembled and replaced, the staff rotates the bolt 42 in the reverse direction, so that the bolt 42 drives the pressure plate 41 to move in the reverse direction, thereby releasing the clamping and fixing effect on the tool, making it easier for the staff to disassemble and replace the tool.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
