[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. The vast majority of tools are machine-made, but some are hand-made. Since the tools used in mechanical manufacturing are basically used for cutting metal materials, the term "tool" is generally understood as metal cutting tools. Tools used for cutting wood are called woodworking tools. In order to process different raw materials and cut the raw materials at different angles, it is often necessary to index the tool, that is, adjust the cutting angle of the tool.

[0003] A search revealed that Chinese Patent Publication No. CN217701394U discloses "an indexable cutting tool comprising: a body, wherein the body is movably connected to a reciprocating drive assembly, the reciprocating drive assembly is movably connected to a driven assembly, the driven assembly is movably connected to a limiting member, the limiting member is fixedly connected to the body, the driven assembly is movably connected to a telescopic member, the telescopic member is movably connected to a cutting assembly, the driven assembly includes a rotating shaft and a gear, the rotating shaft is rotatably connected to the reciprocating drive assembly, the rotating shaft is fixedly connected to the gear, the gear meshes with the limiting member, and the gear is fixedly connected to the telescopic member";

[0004] However, in the process of implementing the relevant technology, the above-mentioned patent has certain technical defects. The patent uses gears to drive the rotating shaft to rotate the cutting component in the horizontal direction to change the cutting angle. This adjustment of the cutting component is mainly for cutting wood vertically downwards. However, when it is necessary to cut wood at a certain angle, the cutting component of the patent cannot achieve this, which makes this type of cutting component have certain limitations. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an indexable cutting tool, which solves the problem that the prior art cannot perform oblique cutting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an indexable cutting tool, including a lifting frame, a movable seat slidably connected to the inner side of the lifting frame, a rotating sleeve rotatably connected to the bottom of the movable seat, a tool assembly provided at the bottom of the rotating sleeve, the tool assembly including a mounting base fixedly connected to the bottom of the rotating sleeve, a rotating box rotatably connected to the inner side of the mounting base, a servo motor fixedly connected to one end of the rotating box, a cutting blade fixedly connected to the output shaft of the servo motor, a connecting plate rotatably connected to one side of the mounting base and coaxially fixed to the rotating box, a cylinder hinged to the outer side of the mounting base, the output end of the cylinder hinged to one end of the connecting plate, and a translation mechanism provided on the movable seat to drive the movable seat to slide by cooperating with the start of the servo motor.

[0007] As a preferred embodiment of this utility model, both ends of the top of the lifting frame are fixedly connected to a second cylinder for driving the lifting frame to move in the vertical direction.

[0008] As a preferred embodiment of this utility model, two guide rods are fixedly connected to both ends of the inner side of the lifting frame, and the two ends of the movable seat are slidably connected to the two guide rods respectively.

[0009] As a preferred technical solution of this utility model, the translation mechanism includes a rotating shaft passing through the rotating sleeve. The rotating shaft is rotatably connected to the rotating sleeve. A traveling gear is fixedly connected to the top of the rotating shaft. A toothed plate is fixedly connected to the inner side of the lifting frame. The traveling gear meshes with the toothed plate. A transmission component is provided at the bottom of the rotating shaft to drive the rotating shaft to rotate by cooperating with the start of a servo motor.

[0010] In a preferred embodiment of this invention, the toothed plate and the guide rod are arranged in parallel, and the lengths of the toothed plate and the guide rod are the same.

[0011] As a preferred embodiment of this utility model, the transmission component includes a first bevel gear, which is fixedly connected to the output shaft of the servo motor. The top of the rotating box is rotatably connected to a second rotating shaft that passes through the top wall of the rotating box. The bottom end of the second rotating shaft is fixedly connected to a second bevel gear that meshes with the first bevel gear. The top end of the second rotating shaft is fixedly connected to a universal coupling, and the top end of the universal coupling is fixedly connected to the first rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. During cutting, the lifting frame is moved downward by controlling the second drive of the cylinder, so that the cutter contacts the wood downward. At the same time, the servo motor is started to drive the cutter to rotate to cut the wood. Meanwhile, the translation mechanism drives the movable seat to slide, so that the cutter moves to cut the wood to achieve the purpose of cutting a large area.

[0014] 2. When the horizontal position of the cutter needs to be adjusted, the rotating sleeve can be rotated to make the entire mounting base rotate, allowing the cutter to rotate horizontally to adjust the horizontal cutting angle. When the cutter needs to cut at an angle, the connecting plate is rotated by controlling the cylinder, which in turn drives the servo motor to rotate longitudinally. This allows the cutter to move longitudinally to adjust the longitudinal cutting angle, thus realizing the cutter's angled cutting function. The entire structure can realize multi-angle adjustment of the cutter to meet different cutting needs in actual wood processing, and has strong versatility. Attached Figure Description

[0020] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, this utility model provides an indexable cutting tool, including a lifting frame 1. Two cylinders 2 are fixedly connected to both ends of the top of the lifting frame 1 to drive the lifting frame 1 to move vertically. A movable seat 4 is slidably connected to the inner side of the lifting frame 1. A rotating sleeve 5 is rotatably connected to the bottom of the movable seat 4. A tool assembly 6 is provided at the bottom of the rotating sleeve 5. The tool assembly 6 includes a mounting base 61 fixedly connected to the bottom of the rotating sleeve 5. A rotating box 62 is rotatably connected to the inner side of the mounting base 61. A servo motor 63 is fixedly connected to one end of the rotating box 62. A cutting blade 64 is fixedly connected to the output shaft of the servo motor 63. A connecting plate 65, coaxially fixed with the rotating box 62, is rotatably connected to one side of the mounting base 61. A cylinder 66 is hinged to the outer side of the mounting base 61. The output end of the cylinder 66 is hinged to one end of the connecting plate 65. The movable seat 4 is provided with a translation mechanism 7 that drives the movable seat 4 to slide by cooperating with the start of the servo motor 63.

[0022] During cutting, the lifting frame 1 is driven to move downward by the control cylinder 2, so that the cutter 64 contacts the wood downward. At the same time, the servo motor 63 is started to drive the cutter 64 to rotate to cut the wood. Meanwhile, the translation mechanism 7 drives the movable seat 4 to slide, so that the cutter 64 moves to cut the wood to achieve the purpose of large-area cutting.

[0023] When the horizontal position of the cutter 64 needs to be adjusted, the rotating sleeve 5 can be rotated to make the mounting base 61 rotate as a whole, so that the cutter 64 can rotate in the horizontal direction to adjust the horizontal cutting angle. When the cutter 64 needs to cut at an angle, the connecting plate 65 is driven to rotate by the control cylinder 66, so that the rotating box 62 drives the servo motor 63 to rotate longitudinally. This makes the cutter 64 move longitudinally to adjust the longitudinal cutting angle, thus realizing the angled cutting function of the cutter 64. The whole structure can realize the multi-angle adjustment of the cutter 64, meet the different cutting needs of actual wood processing, and has strong versatility.

[0024] The lifting frame 1 has two guide rods 3 fixedly connected to both ends of its inner side, and the movable seat 4 has two ends slidably connected to the two guide rods 3 respectively. The guide rods 3 guide the movable seat 4, ensuring that the movable seat 4 can move smoothly.

[0025] The translation mechanism 7 includes a rotating shaft 71 that passes through the rotating sleeve 5. The rotating shaft 71 is rotatably connected to the rotating sleeve 5. A traveling gear 72 is fixedly connected to the top of the rotating shaft 71. A toothed plate 73 is fixedly connected to the inner side of the lifting frame 1. The traveling gear 72 meshes with the toothed plate 73. A transmission component 67 is provided at the bottom of the rotating shaft 71 to drive the rotating shaft 71 to rotate by cooperating with the start of the servo motor 63. The toothed plate 73 is arranged parallel to the guide rod 3, and the toothed plate 73 and the guide rod 3 are aligned. The lengths are the same. The transmission component 67 includes a bevel gear 671, which is fixedly connected to the output shaft of the servo motor 63. The top of the rotating box 62 is rotatably connected to a rotating shaft 672 that passes through the top wall of the rotating box 62. The bottom end of the rotating shaft 672 is fixedly connected to a bevel gear 673 that meshes with the bevel gear 671. The top end of the rotating shaft 672 is fixedly connected to a universal coupling 674, and the top end of the universal coupling 674 is fixedly connected to the rotating shaft 71.

[0026] Working principle: During cutting, the lifting frame 1 is driven downward by the control cylinder 2, so that the cutter 64 contacts the wood downward. At the same time, the servo motor 63 is started to drive the cutter 64 to rotate to cut the wood. At this time, the bevel gear 671 rotates synchronously, so that the bevel gear 673 drives the rotating shaft 672 to rotate, so that the universal coupling 674 drives the rotating shaft 71 to rotate, thereby causing the travel gear 72 to rotate and roll along the toothed plate 73, which in turn causes the movable seat 4 to move and move, so that the cutter 64 can move and cut the wood to achieve the purpose of large-area cutting.
