Technical Field

[0001] This utility model relates to the field of milling cutter technology, and in particular to a bidirectional adjustable tool holder milling cutter. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] A cutter holder type end mill is a type of end mill in which the insert is fixed to the cutter holder by a tool clip. In existing technologies, the cutter holder has a fixed position, making it impossible to fine-tune the insert's position according to usage requirements. Adjustment can only be made by replacing the tool clip, which is very inconvenient.

[0004] In view of this, there is an urgent need for a bidirectional adjustable tool holder type end mill to solve the above problems. Summary of the Invention

[0006] The inner side of the tool holder is provided with an adjusting pad and a first adjusting screw. The contact surface between the side of the adjusting pad away from the tool holder and the tool holder is an inclined surface that is inclined to the axial direction of the tool holder. When the first adjusting screw is rotated, the adjusting pad moves along the axial direction of the tool holder.

[0007] Its further feature is that,

[0008] The tool holder is horizontally provided with two locking screws, and the tool holder is fixed to the tool holder by the two locking screws.

[0009] The tool holder is provided with two adjustment holes extending in the horizontal direction. The adjustment holes are waist-shaped holes extending in the axial direction of the tool holder, and the two locking screws are respectively inserted into the two adjustment holes.

[0010] The bottom of the tool holder is threaded with a second adjusting screw, and the tool holder has a limit plane on the side of the second adjusting screw away from the tool holder.

[0011] The head of the second adjusting screw is provided with several connecting holes extending circumferentially along the axis perpendicular to the tool holder.

[0012] The two locking screws are distributed along the axial direction of the tool holder, and the adjusting pad is located on the same side of the two locking screws.

[0013] The first adjusting screw is threadedly connected to the tool holder.

[0014] The adjusting pad has a slot on the side away from the tool holder, and the head of the first adjusting screw is engaged in the slot. The axial direction of the first adjusting screw is consistent with the axial direction of the tool holder.

[0015] The side of the blade holder closest to the adjusting pad is the positioning surface, which is in contact with the side of the adjusting pad.

[0016] The blade is fixed to the blade holder by a fixing screw.

[0017] The above-described structure of this utility model can achieve the following beneficial effects:

[0018] During installation, first fix the blade holder to the blade holder using two locking screws. Then, rotate the first adjusting screw to move the adjusting shim, changing the position of the side of the adjusting shim closest to the blade holder. Then, tighten the two locking screws to make the positioning surface of the blade holder fit against the adjusting shim, completing the installation of the blade holder and achieving the purpose of adjusting the blade position. This eliminates the need to replace the blade holder, allowing the distance between the blade and the axis of the blade holder to be at different values, which is convenient and quick.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0025] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0026] Reference Figure 1-3 A bidirectional adjustable tool holder type end mill includes: a tool holder 1, a plurality of tool clamping grooves 11 are provided on the circumferential side of the tool holder 1, a tool clamp 2 is provided at each of the tool clamping grooves 11, and a cutting blade 3 is provided on the side of the tool clamp 2 away from the tool holder 1.

[0027] The inner side of the tool holder 2 is provided with an adjusting pad 4 and a first adjusting screw 5. The contact surface between the side of the adjusting pad 4 away from the tool holder 2 and the tool holder 1 is an inclined surface that is inclined to the axial direction of the tool holder 1 (the inclined direction of the inclined surface can be from the top of the tool holder 1 to the bottom of the tool holder 1 and extends outward from the tool holder 2). The first adjusting screw 5 is rotated to make the adjusting pad 4 move along the axial direction of the tool holder 1.

[0028] Based on the above features, an adjusting pad 4 (the adjusting pad 4 can be a trapezoidal pad) is set in the diameter direction of the tool holder 1. The adjusting pad 4 is driven to move in the axial direction of the tool holder 1 by the first adjusting screw 5. Since the contact surface between the adjusting pad 4 and the tool holder 1 is an inclined surface, and the adjusting pad 4 is set between the tool clip 2 and the tool holder 1, the position of the tool clip 2 follows the movement of the adjusting pad 4. The distance between the cutting edge of the blade 3 and the axis of the tool holder 1 will change, thereby achieving the purpose of adjusting the position of the blade 3.

[0029] like Figure 1 and Figure 2 As shown, two locking screws 6 are horizontally arranged on the tool holder 2. The tool holder 2 is fixed to the tool holder 1 by the two locking screws 6. The double screw (two locking screws 6) locking method is adopted. With the extended tool holder 2, the contact area between the extended tool holder 2 and the tool holder 1 is increased, which increases the stability. At the same time, the locking of the two locking screws 6 also increases the reliability of the tool holder 2 installation.

[0030] like Figure 1 and Figure 2As shown, the tool holder 2 is provided with two horizontally extending adjustment holes 21. The adjustment holes 21 are waist-shaped holes extending along the axial direction of the tool holder 1. Two locking screws 6 are respectively inserted into the two adjustment holes 21. In this way, the tool holder 2 can move along the axial direction of the tool holder 1 to achieve the purpose of adjusting the position of the blade 3, further improving the flexibility of blade 3 adjustment. In addition, in order to facilitate the adjustment of the relative position of the tool holder 2 in the axial direction of the tool holder 1, the bottom of the tool holder 2 is threaded with a second adjustment screw 7. The tool holder 1 is provided with a limiting plane 12 on the side of the second adjustment screw 7 away from the tool holder 2. In this way, during installation, the head of the second adjustment screw 7 always abuts against the limiting plane 12. Therefore, by turning the second adjustment screw 7, the axial position of the tool holder 2 can be precisely adjusted. The head of the second adjustment screw 7 is provided with several connecting holes 71 extending perpendicular to the axial direction of the tool holder 1. By inserting an auxiliary tool (rod-shaped) into the connecting holes 71, it is easy to rotate the second adjustment screw 7.

[0031] A further optimization is that the relative positions of the locking screws 6 and the adjusting shim 4 are as follows: the two locking screws 6 are distributed along the axial direction of the tool holder 1, and the adjusting shim 4 is set on the same side of the two locking screws 6. In this way, the distance between the cutting edge of the blade 3 and the axis of the tool holder 1 can be adjusted more quickly.

[0032] like Figure 1 and Figure 3 As shown, in order to adjust the position of the adjusting pad 4, the first adjusting screw 5 is threadedly connected to the tool holder 1, and a groove 41 is provided on the side of the adjusting pad 4 away from the tool holder 2. The head of the first adjusting screw 5 is locked in the groove 41, and the axial direction of the first adjusting screw 5 is consistent with the axial direction of the tool holder 1. Thus, by turning the first adjusting screw 5, the position of the head of the first adjusting screw 5 changes, thereby adjusting the position of the adjusting pad 4.

[0033] A further optimization is that the side of the blade clip 2 closest to the adjusting pad 4 is the positioning surface, which fits against the side of the adjusting pad 4. The adjusting pad 4 and the positioning surface of the blade clip 2 are completely fitted together, maximizing the contact area and ensuring the stability of the blade clip 2 during adjustment.

[0034] A further optimization is that the blade 3 is fixed to the blade holder 2 by a fixing screw, making it easy to install and remove the blade 3.

[0035] In summary, an adjusting shim 4 is set in the diameter direction of the tool holder 1. The adjusting shim 4 is driven to move axially in the tool holder 1 by the first adjusting screw 5. Because the contact surface between the adjusting shim 4 and the tool holder 1 is an inclined surface, and the adjusting shim 4 is set between the tool clip 2 and the tool holder 1; during installation, the tool clip 2 is first fixed to the tool holder 1 by the two locking screws 6 (the two locking screws 6 are in the loose state), then the first adjusting screw 5 is rotated to move the adjusting shim 4, so that the position of the end face of the adjusting shim 4 near the tool clip 2 changes, and then the two locking screws 6 are tightened so that the positioning surface of the tool clip 2 is in contact with the adjusting shim 4, thus completing the installation of the tool clip 2 and achieving the purpose of adjusting the position of the blade 3. Therefore, the distance between the blade 3 and the axis of the tool holder 1 can be at different values ​​without replacing the tool clip 2, which is convenient and quick.

[0036] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
