Combination structure of tool holder and tool holder

This creation department is related to the turning tool, especially regarding the combination of a turning tool holder and a turning tool holder.

Due to the different processing requirements and the inevitable wear of the blades, the tools often have replacement requirements. The tools are divided into tool holders for mounting the blades and tool holders for mounting on the machine table. The tool holders and the tool holders are bolted. For fixing and replacement, it is only necessary to disassemble the seat part. Compared with the whole set of tools, the holder is lighter in weight and the replacement time and difficulty are relatively low.

However, the conventional fixing method is simply bolting, and the fixing bolt is easy to loose during the machining process, thereby causing the relative position of the knife seat and the tool holder to change, which affects the processing quality.

Therefore, it is necessary to provide a novel and progressive combination of a tool holder and a tool holder to solve the above problems.

The main purpose of this creation is to provide a combination structure of the tool holder and the tool holder, which can reliably abut the knife seat and prevent looseness; and the structure and the processing are simple, the assembly is easy and suitable for various combined tools.

In order to achieve the above object, the present invention provides a combination structure of a turning tool holder and a tool holder, comprising: a turning tool bar, a turning tool seat and at least one fastening member. The first connecting portion is laterally provided with at least one first hole, and each of the first holes has a first central axis. a second set of joints that are inserted into the first set of joints, the second set of joints are laterally provided with at least one second hole, and each of the second holes has a second center An axis, when the first and second sets of portions are axially offset, each of the second central axes is offset from the corresponding one of the first central axes and does not overlap. Wherein at least one of the corresponding first and second holes is provided with one of the fastening members, and the axial direction of the fastening member is reversely pressed against the top.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Please refer to FIG. 1 to FIG. 4 , which shows a preferred embodiment of the present invention. The combination of the tool holder and the tool holder 1 includes a turning tool bar 10 , a tool holder 20 and at least one fastening member 30 . .

The first shank 11 is axially disposed with a first connecting portion 11 , and the first connecting portion 11 is laterally disposed with at least one first hole 31 , and each of the first holes 31 has a first central axis 32 . The tool holder 20 is axially disposed with a second set of joints 21 that are inserted into the first set of joints 11 , and the second set of joints 21 is laterally provided with at least one second hole 33 , each of the second The bore 33 has a second central axis 34 that is offset from the corresponding one of the first central axes 32 and does not overlap when the first and second sets of portions are axially offset. At least one of the corresponding first hole 31 and the second hole 33 is provided with one of the fastening members 30, and is axially abutted against the fastening member 30 in the opposite direction. By the structure in which the first central axis 32 and the second central axis 34 are dislocated, the fastening member 30 can provide a thrust force for pressing the tool holder 20 along the axial direction of the tool holder 10, and then The reaction force of the thrust is utilized to prevent the fastening member 30 from being loosened due to vibration during machining and the looseness of the tool holder 20. In this embodiment, the first central axis 32 and the second central axis 34 are offset from the axial direction of the tool holder 10 by 0.5 mm to 0.8 mm.

In this embodiment, the first set of connecting portions 11 are provided with two opposite first holes 31 on two sides, but two or more first holes may be provided at equal angular intervals or at arbitrary intervals. One of the first and second sets of joints 11, 21 includes a slot 12 and the other includes a plug 22. In more detail, the first end face 13 of the first set of joints 11 is recessed with the slot 12, and the second end face 23 of the second set of joints 21 is convexly disposed with the plug 22, but the slot and the plug can be The second set of joints and the first set of joints are respectively provided in an interchangeable manner. The first end surface 13 abuts against the second end surface 23, and a groove bottom surface 14 of the slot 12 is spaced apart from one end surface 24 of the plug 22 without abutting.

Preferably, a flexible portion 40 is pressed between a circumferential surface 25 of the plug 22 and a groove wall 15 of the slot 12. The flexible portion 40 can be, but not limited to, rubber or plastic (for example, Teflon). Self-lubricating material). Specifically, the peripheral surface 25 of the plug 22 is provided with at least one annular groove 26, and the flexible portion 40 includes at least one flexible ring 41 received in the at least one annular groove 26 and protruding radially from the at least one annular groove 26. In the embodiment, the flexible portion 40 includes a ring groove 26 and a flexible ring 41. However, two or more ring grooves and a flexible ring may be disposed along the axial direction of the plug 22. By means of the at least one flexible ring 41, the tool holder 20 can be initially fixed on the tool holder 10 for installation, and also has shock absorption and prevents foreign matter such as chips and cutting fluid from entering the tool holder and the tool holder. Combines the functions inside structure 1.

Preferably, the bottom of the slot of the slot 12 is radially provided with a slot 16 , and the plug 22 is provided with an annular recess 27 connected to the second end surface 23 , and the plug 22 partially extends into the slot 16 . By processing the annular recess 27 and the expanded groove 16, the material remaining by the tool interference can be removed, and the first end face 13 and the second end face 23 can be surely abutted.

Preferably, each of the fastening members 30 includes a tapered end 35, and each of the second holes 33 includes a tapered flank 36 of the tapered end 35, the tapered end 35 resisting the tapered flaring 36. With the tapered end 35 and the tapered structure of the taper flare 36, the component force generated when the fastener is locked causes the tool holder 20 to be axially and strongly adhered to the tool holder 10, The fastening member 30 can also be introduced into the second hole 33 more easily. Each of the fastening members 30 is preferably a screw of a screw, each of the first holes 31 being a screw hole, each of the tapered ends 35 being in the shape of a cone, and each of the second holes 33 is a tapered hole.

In this embodiment, the first end surface 13 is radially convexly disposed with two opposite pins 17, but two or more pins may be disposed at equal angular intervals or at arbitrary intervals, and the second end surface 23 is radially recessed. The jacks 28 of the two pins 17 are accommodated, and each of the pins 17 includes an arcuate surface 171 in a radial plane, and each of the jacks 28 includes a radially outer curved concave surface 281, the arc convex surface 171 and the arc The shapes of the concave surfaces 281 are matched and abutted. The two pins 17 can withstand partial torque and have a positioning effect when installed. The curved surface design can reduce the manufacturing difficulty of the pin 17 and the socket 28 and make assembly easier.

In summary, the first hole and the second hole are disposed on the lateral side of the first set of joints and the second set of joints, and the car is pierced by the tapered end of the fastening member. The second hole of the knife seat achieves the effect of tightening the tool holder, and the flexible portion can be disposed on the circumferential surface of the plug or the shape-fitted pin can be disposed on the end surface of the assembly portion to improve assembly and shock absorption effects.
