[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0026] The terms "comprising" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily need to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0027] The following further describes the present application with reference to the drawings:

[0028] AsFigures 1 to 6 As shown, the present application provides a shank groove milling tool, including a groove milling table 1, on which at least one groove milling station 11 is arranged, the groove milling station 11 is suitable for accommodating a tool handle 4, and groove milling molds 2 are arranged one by one at the groove milling stations 11, and a fixing device 3 is arranged around the groove milling station 11, the fixing device 3 includes a telescopic part 31 and a driving part 32, and the driving part 32 is suitable for making the telescopic part 31 enter the groove milling station 11 or detach from the groove milling station 11, and the telescopic design of the fixing device 3 can reduce the difficulty of placing and installing the tool handle 4 and improve the operating efficiency.

[0029] When the telescopic part 31 extends into the slot milling station 11, the telescopic part 31 is suitable for making the tool handle 4 cooperate with at least two end faces 221 of the slot milling mold 2. The telescopic part 31 and the multiple end faces 221 of the slot milling mold 2 cooperate to fix the tool handle 4 in a manner that can improve stability. By increasing the force-bearing area with the slot milling mold 2 and dispersing the force direction, the probability of deformation of the slot milling mold 2 due to excessive clamping force is reduced, thereby increasing the service life of the slot milling mold 2 and the stability of long-term use.

[0030] In some embodiments, a cavity 21 is opened around the slot milling mold 2, and the fixing device 3 is arranged in the cavity 21. The driving part 32 is suitable for making the telescopic part 31 enter and exit the cavity 21. Combining the fixing device 3 with the slot milling mold 2 can reduce the number of parts and enable the slot milling mold 2 to bear the reaction force received by the fixing device 3, thereby improving the structural stability and structural strength.

[0031] like Figure 3 and 4 In the illustrated embodiment, a piston 311 is provided at one end of the telescopic portion 31 away from the milling station 11, and the piston 311 is suitable for dividing the cavity 21 into a first chamber 211 and a second chamber 212. The driving portion 32 includes a first channel 321 and a second channel 322. The first channel 321 is suitable for connecting to the first chamber 211, and the second channel 322 is suitable for connecting to the second chamber 212. The first channel 321 is suitable for filling or extracting a medium into the first chamber 211, and the second channel 322 is suitable for filling or extracting a medium into the second chamber 212. A pressure difference is generated between the first chamber 211 and the second chamber 212 by filling or extracting the medium, so that the piston 311 can move with the change of the pressure difference, thereby driving the telescopic portion 31 to move as a whole.

[0032] In some embodiments, the medium entering the first chamber 211 and the second chamber 212 is preferably gas or liquid.

[0033] In some embodiments, the first chamber 211 is close to the milling groove station 11. The first channel 321 and the first chamber 211 are adapted to circulate gas, and the second channel 322 and the second chamber 212 are adapted to circulate liquid. It can be understood that hydraulic drive can enable the telescopic part 31 to obtain a higher acting force on the tool holder 4, thereby improving the cooperation stability among the tool holder 4, the milling groove die 2, and the telescopic part 31. The first channel 321 can be in the form of a vent hole and act passively following the pressure change in the second chamber 212, which can effectively reduce the number of components and the structural complexity. When used in conjunction with the reset part 33, the acting forces among the balance reset part 33, the first chamber 211, and the second chamber 212 can be utilized.

[0034] As Figure 4 In the embodiment shown, the first chamber 211 is close to the milling groove station 11. A reset part 33 is arranged in the first chamber 211. The reset part 33 is adapted to enable the telescopic part 31 to enter the cavity 21. Specifically, the reset part 33 can be clamped between the milling groove die 2 and the piston 311, and the piston 311 is pushed to move by the force generated when the reset part 33 is compressed and then reset.

[0035] In some embodiments, the reset part 33 preferably uses a spring, which is convenient to install and has a low cost.

[0036] In some embodiments, a positioning part 22 is arranged on the milling groove die 2. The telescopic part 31 is inclined towards the positioning part 22. The telescopic part 31 is adapted to enable the tool holder 4 to be in abutting cooperation with at least two end faces 221 on the positioning part 22. The form of the telescopic part 31 being inclined and combined with the abutting cooperation of at least two end faces 221 can disperse the force received by the positioning part 22 when abutting against the tool holder 4 and increase the contact area, thereby improving the cooperation stability.

[0037] In some embodiments, the telescopic part 31 is adapted to enable the tool holder 4 to be in abutting cooperation with at least two substantially parallel end faces 221 on the positioning part 22, which can increase the force-bearing area and evenly disperse the force exerted by the tool holder 4 pressing on the positioning part 22 to improve the cooperation stability.

[0038] In some embodiments, the telescopic part 31 is adapted to enable the tool holder 4 to be in abutting cooperation with at least two adjacent and substantially perpendicular end faces 221 on the positioning part 22, which can make the structural strength of the positioning part 22 higher and evenly disperse the force exerted by the tool holder 4 pressing on the positioning part 22 to improve the cooperation stability.

[0039] As Figure 4 In the embodiment shown, the positioning part 22 is a hoop structure. One end of the tool holder 4 can be inserted and nested into the positioning part 22 and is adapted to be in clamping cooperation and fixation with the positioning part 22 under the action of the telescopic part 31.

[0040] AsFigure 2 In the illustrated embodiment, the number of the fixing devices 3 is multiple, and the fixing devices 3 are arranged at equal circumferential intervals along the milling groove station 11, which can improve the fastening effect of the fixing devices 3 on the tool shank 4. At the same time, the fastening force applied to the tool shank 4 can be more uniform, and the fastening stability of the tool shank 4 is improved.

[0041] In some embodiments, when the fixing device 3 is arranged on the milling groove die 2, the multiple number of the fixing devices 3 can improve the fastening effect between the tool shank 4 and the milling groove die 2, and improve the positioning stability between the tool shank 4 and the milling groove die 2.

[0042] As Figure 5 and 6 In the illustrated embodiment, a rotating shaft 12 is arranged on the milling groove table 1, the milling groove station 11 is arranged on the rotating shaft 12, the rotating shaft 12 is controlled by a motor, and the rotating shaft 12 is adapted to rotate and cause the milling groove die 2 to turn over. Through the rotating shaft 12, the milling groove die 2 can be turned over in multiple directions, and thereby the machining of the tool shank 4 in different orientations in the milling groove die 2 can be realized, without the need to re-disassemble, take and position the tool shank 4 again, and the tool shank 4 can actively cooperate with the processing equipment 5 for machining through turning over, so as to reduce the adjustment of the processing equipment 5 and improve the processing efficiency and processing accuracy.

[0043] As Figure 5 In the illustrated embodiment, the number of the milling groove stations 11 can be set to be multiple and arranged along the axial direction of the rotating shaft 12. The rotation of the rotating shaft 12 can cause the milling groove dies 2 on the multiple milling groove stations 11 to turn over to the same state, so as to realize multi-station machining and further improve the processing efficiency.

[0044] As Figure 5 In the illustrated embodiment, the milling groove die 2 protrudes from the milling groove station 11, so that the milling groove die 2 is exposed to the outside, which is convenient for machining the tool shank 4 in the milling groove die 2. Milling groove holes 23 are formed on multiple sides of the milling groove die 2 in the rotation plane of the rotating shaft 12. When the rotating shaft 12 rotates, the side surface of the milling groove die 2 in the rotation plane of the rotating shaft 12 can be turned over to the same plane in turn through rotation, so that the processing equipment 5 can directly machine the side surface of the milling groove die 2 in this plane without re-adjusting the position, and the multi-side guiding machining of the tool shank 4 can be realized through the milling groove holes 23, thereby improving the processing efficiency.

[0045] In the present application, the flipping of the milling groove die 2 is preferably a 90° flip. When milling groove holes 23 are provided on the left side and / or the right side of the milling groove die 2, the processing device 5 can, after the milling groove die 2 is flipped by 90°, pass through the milling groove holes 23 to machine the left side or the right side of the tool shank 4. Since the tool shank 4 and the milling groove die 2 always remain in a fastened state and the relative positions remain unchanged, the tool shank 4 groove holes machined after flipping have higher symmetry and accuracy.

[0046] As Figure 5 shown in the embodiment, a pressure integration module 121 is provided on the rotating shaft 12. The pressure integration module 121 is adapted to connect each fixing device 3. The pressure integration module 121 can connect the first channel 321 and / or the second channel 322 on each milling groove die 2, and inject or extract a medium into or from the first chamber 211 and / or the second chamber 212, which can ensure the consistency of the injection or extraction of the medium. The pressure integration module 121 rotates with the rotating shaft 12, which can reduce the wire pulling and interference during the rotation process and improve the operation stability.

[0047] In some embodiments, the pressure integration module 121 can be an oil circuit integration block and is adapted to communicate with the first channel 321 and / or the second channel 322, and realize the pressure change of the first chamber 211 and / or the second chamber 212 by injecting or extracting oil, and can increase or decrease the pressure according to actual requirements.

[0048] In some embodiments, when the pressure integration module 121 is an oil circuit integration block, it is adapted to connect the second channel 322, and realize the pressure increase of the second chamber 212 by injecting oil, which can improve the fixing ability of the fixing device 3 and the stability of fixing the tool shank 4 on the milling groove die 2.

Those skilled in the art should understand that the present application is not limited by the above embodiments.
