[0034] See Figure 1-13As shown, as an embodiment of the present invention, a locking knife holder is provided, comprising a base 3 and a vertical knife holder 1 and a horizontal knife holder 2 detachably mounted on the base 3, and the base 3 can be adapted to vertical knife holders 1 and horizontal knife holders 2 of various specifications, the base 3 comprises a bottom plate 33 and a first support frame 31 and a second support frame 32 arranged on the bottom plate 33, the first support frame 31 is provided with a through hole 6 passing through from top to bottom, a first limiting portion is provided on the upper side of the outer periphery of the first support frame 31 corresponding to the through hole 6, a first limiting matching portion is provided on the bottom side of the vertical knife holder 1, the first limiting portion and the first limiting matching portion correspond to limit matching to fix the vertical knife holder 1 on the first support frame 31 A second limiting portion is provided on the second support frame 32, and a second limiting matching portion is provided on the horizontal tool holder 2. The second limiting portion and the second limiting matching portion correspond to the limiting matching portion to fix the horizontal tool holder 2 on the second support frame 32. The utility model only needs one base 3 to adapt to a variety of vertical tool holders 1 and horizontal tool holders 2 of different specifications, and then adapt to the disassembly and assembly of CNC tool holders of various specifications and types. It has higher versatility and solves the problem of large space occupation in the off-machine tool installation link in CNC machining. It has smaller space and lower cost. The vertical tool holder 1 and the horizontal tool holder 2 do not need to be screwed and can be installed and used immediately. The replacement operation is simpler and faster, which improves work efficiency.

[0035] In this embodiment, the first limiting portion includes an annular groove 7 and a protrusion 8 provided at the annular groove 7. The vertical tool holder 1 includes a cylindrical body. The first limiting matching portion includes a clamping groove 9 provided on the periphery of the bottom side of the cylindrical body. The protrusion 8 and the clamping groove 9 are correspondingly limited and matched. Among them, there are multiple protrusions 8 and the clamping groove 9, which correspond one to one. The multiple protrusions 8 are evenly arranged in an annular shape on the annular groove 7, and the multiple clamping grooves 9 are evenly arranged in an annular shape on the periphery of the bottom side of the cylindrical body. This arrangement enables the vertical tool holder 1 to rotate circumferentially to adjust its installation angle position on the first support frame 31, and further enables the tool holder to rotate circumferentially to adjust its installation angle position. It can be applied to special scenarios such as disassembling a drill bit with a three-jaw tool holder using a crescent-shaped tool removal wrench, and has a wider range of applications.

[0036] In this embodiment, a vertical through-hole 4 is provided within the vertical knife holder 1. This hole 4 is used to allow one end of the knife handle to pass through and be installed therein. First retaining blocks 5 are provided on the top of the vertical knife holder 1, corresponding to the periphery of the hole 4. These first retaining blocks 5 are designed to engage with corresponding notches on the raised ring of the knife handle to restrict circumferential rotation of the knife handle. Specifically, two first retaining blocks 5 are provided, one on each opposite side of the hole 4, to provide a more effective retaining effect on the knife handle and provide a more stable installation.

[0037] In this embodiment, the base 3 is a steel base, and the first support frame 31 is L-shaped, which includes a vertical support plate 311 and a horizontal support plate 312. The clearance hole 4 is located on the horizontal support plate 312, and the horizontal support plate 312 is integrally connected with the second support frame 32, so that the base 3 has better rigidity and is not easy to be broken.

[0038] In this embodiment, the second limiting portion includes a limiting slot 10 arranged in the second support frame 32. The shape and size of the cross section of the limiting slot 10 correspond to the shape and size of the cross section of the horizontal tool holder 2. The horizontal tool holder 2 is inserted downward and fixed in the limiting slot 10, so that the limiting slot 10 can limit the front, back, left and right directions of the horizontal tool holder 2, thereby ensuring the installation stability of the horizontal tool holder 2. The pin-type design can realize the horizontal tool holder 2 to be installed and used immediately, which is convenient to operate.

[0039] Specifically, both sides of the length direction of the horizontal tool holder 2 and the both sides of the length direction of the limiting slot 10 are dovetail-shaped, which further improves the insertion accuracy and stability of the horizontal tool holder 2 and the limiting slot 10; the second support frame 32 is provided with a clearance notch 11 above both sides of the width direction corresponding to the limiting slot 10, which is used to make way for the top two sides of the horizontal tool holder 2, making it convenient for the user to grab the horizontal tool holder 2 by hand and pull the limiting slot 10 upward.

[0040] In this embodiment, a tool handle placement position 12 is provided at the top of the horizontal tool holder 2, and a second clamping block 13 and an arc groove 14 are provided at the tool handle placement position 12. The arc groove 14 is located on opposite sides of the second clamping block 13. The second clamping block 13 is used to cooperate with the corresponding notch on the convex ring of the tool handle to limit the rotation of the tool handle in the circumferential direction, and the arc groove 14 is used to cooperate with the corresponding convex ring of the tool handle to limit the movement of the tool handle in the axial direction.

[0041] Among them, screw holes 15 are provided on the vertical knife holder 1 and the horizontal knife holder 2, so that when the vertical knife holder 1 and the horizontal knife holder 2 are stuck, it is convenient to insert an external tool into the screw hole 15 to remove them.

[0042] In this embodiment, the vertical tool holder 1 and the horizontal tool holder 2 are aluminum tool holders, and the vertical tool holder 1 and the horizontal tool holder 2 have four different specifications and models, namely BBT30, BBT40, BBT50, and HSK models, which are respectively provided for the corresponding installation of tool handles of BBT30, BBT40, BBT50, and HSK models. Among them, the differences between the vertical tool holders 1 of models BBT30, BBT40, and BBT50 are specifically reflected in the different diameters of the makeshift holes 4 and the different spacings between the two makeshift blocks, while the differences between the horizontal tool holders 2 of models BBT30, BBT40, and BBT50 are specifically reflected in the different sizes of the arc grooves 14.

[0043] And as Figure 12 and13 As shown, the vertical tool holder 1 of the HSK40 model is in the shape of a convex character, which includes an upper cylinder and a lower cylinder coaxially arranged above and below, and a clearance hole 4 is provided in the vertical tool holder 1, which is through and through. The clearance hole 4 is used for one end of the HSK model tool handle to pass through and be installed therein, and a plurality of limiting convex strips 16 are provided on the peripheral hole wall of the clearance hole 4, which are used to cooperate with the corresponding notches on the convex ring of the tool handle to limit the rotation of the tool handle in the circumferential direction.

[0044] In this embodiment, the CNC tool holder is the tool holder of an existing CNC tool, and its structure is prior art, so no further description is given here.

[0045] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
