Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, and in particular to a tool with adjustable surface roughness. Background Art

[0002] In the field of machining, various types of cutting tools are usually needed. Cutting tools are tools used for cutting in mechanical manufacturing. In the process of machining mechanical parts, cutting tools are often used to machine the surface of the parts. When machining with cutting tools, the surface roughness needs to be considered. The surface roughness of the machining tool refers to the degree of unevenness or surface roughness of the machined surface obtained during the machining process.

[0003] For example, Chinese Patent Publication No. CN217018649U discloses a valve body eccentric boring tool, including a tool holder, on both the left and right sides of the tool holder are fixedly connected to cutting edges, and on both the front and rear sides of the tool holder are equipped with chip removal spiral grooves. Although it can also make good improvements for deep cavities with large eccentric distances, the chip removal capability is also improved to a certain extent.

[0004] However, because the blade position is fixed and cannot be fine-tuned, the tool type is limited and can only drill certain types of holes. The radial or axial depth of the blade cannot be fine-tuned, meaning the blade position cannot be adjusted according to the actual machining situation. When it is necessary to adjust the machining roughness, the tool needs to be replaced, which reduces machining efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a roughness adjustable cutting tool to solve the problem that the cutting blades in existing cutting tools are fixed and cannot be finely adjusted radially and axially, making it difficult to adjust the roughness of the cutting tool during machining according to the actual operating conditions.

[0006] To achieve the above objectives, this utility model provides a tool with adjustable roughness, including a tool holder. The end of the tool holder is provided with a plurality of mounting slots for placing the blade, and at least one of the mounting slots is provided with an adjustment part, and the remaining mounting slots are fixedly connected with mounting seats for mounting the blade. The adjustment part includes an axial adjustment part for axially adjusting the blade and a radial adjustment part for radially adjusting the blade.

[0007] Preferably, the blade is mounted and fixed on the mounting base by screws.

[0008] Preferably, the axial adjustment part includes an axial strip groove formed in the mounting groove, an axial screw is rotatably connected in the axial strip groove, an axial sleeve is threadedly connected to the axial screw, and a radial adjustment part is disposed on the axial sleeve.

[0009] Preferably, the radial adjustment part includes a movable plate fixedly connected to the axial threaded sleeve, the movable plate having a radial movement groove, a radial screw being rotatably connected in the radial movement groove, a radial threaded sleeve being threaded onto the radial screw, the blade being fixedly installed on the radial threaded sleeve, and a drive part for driving the radial screw to rotate being provided in the radial movement groove.

[0010] Preferably, the driving part includes a worm gear fixedly sleeved on a radial screw, a placement groove is provided in the radial moving groove, and a worm gear meshing with the worm gear is rotatably connected in the placement groove.

[0011] Preferably, both the end of the axial screw and the end of the worm gear are provided with cross grooves.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a roughness adjustable cutting tool, which, through the setting of an axial adjustment part and a radial adjustment part, can adjust at least one blade in the mounting groove, adjust the radial or axial depth of the cutting tip, control the cutting tip depth, and fix the position of the remaining blades, thereby achieving the purpose of controllable product (hole) roughness.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a roughness adjustable cutting tool includes a tool holder 1. The end of the tool holder 1 is provided with a plurality of mounting slots for placing the cutting blade 2. At least one mounting slot is provided with an adjustment part, and the remaining mounting slots are fixedly connected with mounting seats 3 for mounting the cutting blade 2. The adjustment part includes an axial adjustment part 4 for axial adjustment of the cutting blade 2 and a radial adjustment part 5 for radial adjustment of the cutting blade 2.

[0023] Tool surface roughness refers to the degree of unevenness or roughness of the machined surface obtained during the machining process. It is an important indicator used to describe the quality of the machined surface.

[0024] The radial and axial depths of the blade 2 can be adjusted by the axial adjustment part 4 and the radial adjustment part 5, thereby adjusting at least one blade 2 in the mounting groove. The radial or axial depth of the blade tip can be adjusted to control the blade tip depth, while the positions of the other blades are fixed, thereby achieving the goal of controllable product hole roughness.

[0025] In a preferred embodiment of this utility model, the blade 2 is mounted and fixed on the mounting base 3 by screws 6, and the blade 2 can also be welded and fixed on the mounting base 3.

[0026] In another preferred embodiment of the present invention, the axial adjustment part 4 includes an axial strip groove formed in the mounting groove, an axial screw 41 is rotatably connected in the axial strip groove, one end of the axial screw 41 passes through the end of the tool holder 1 and is exposed at the end of the tool holder 1, an axial sleeve 42 is threadedly connected to the axial screw 41, and a radial adjustment part 5 is provided on the axial sleeve 42.

[0027] When it is necessary to adjust the axial depth of at least one blade 2, the axial screw 41 is rotated. Since the axial screw 41 is threadedly connected to the axial sleeve 42 and the axial groove restricts the rotation of the axial sleeve 42, the axial sleeve 42 can move along the axial screw 41, which will drive the radial adjustment part 5 and the blade 2 to move, thereby achieving the purpose of adjusting the axial depth of the blade 2.

[0028] In another preferred embodiment of the present invention, the radial adjustment part 5 includes a movable plate 51 fixedly connected to the axial threaded sleeve 42. The movable plate 51 has a radial moving groove, and a radial screw 52 is rotatably connected in the radial moving groove. A radial threaded sleeve 53 is threadedly connected to the radial screw 52. A blade 2 is fixedly installed on the radial threaded sleeve 53. The blade 2 can be fixed on the radial threaded sleeve 53 by welding. A drive part 8 for driving the radial screw 52 to rotate is also provided in the radial moving groove.

[0029] When it is necessary to adjust the radial depth of the blade 2, the radial screw 52 is driven to rotate by the drive unit 8, and the radial screw sleeve 53 can move on the radial screw 52, ​​thereby driving the blade 2 to move radially and achieving the purpose of adjusting the radial depth of the blade 2.

[0030] It should be noted that the drive unit 8 includes a worm gear 81 fixedly sleeved on the radial screw 52. A placement groove is provided in the radial moving groove. A worm 82 that meshes with the worm gear 81 is rotatably connected in the placement groove. The end of the worm 82 passes through the moving plate 51 and is exposed on the surface of the moving plate 51. A cross groove 7 is provided at the end of the axial screw 41 and the end of the worm 82. The cross groove 7 facilitates the rotation of the worm 82 and the axial screw 41 with a Phillips screwdriver.

[0031] When it is necessary to adjust the radial depth of the blade 2, the worm 82 is driven to rotate by a Phillips screwdriver. Since the worm 82 meshes with the worm wheel 81, the rotation of the worm 82 will drive the worm wheel 81 to rotate, thereby driving the radial screw 52 to rotate. Since the radial sleeve 53 is threadedly connected to the radial screw 52, ​​and the radial movement groove restricts the rotation of the radial sleeve 53, the radial sleeve 53 can move on the radial screw 52, ​​thereby adjusting the radial depth of the blade 2.

[0032] By adjusting the blade 2 in at least one mounting slot, the radial or axial depth of the blade tip can be adjusted to control the blade tip depth, while the positions of the remaining blades 2 are fixed, thereby achieving the goal of controllable product (hole) roughness.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
