Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a high-efficiency multi-size concentric circle cutting tool. Background Technology

[0002] Currently, when cutting concentric circles of multiple sizes, multiple cutting tools are required. Each tool change will affect the accuracy of the concentric circle of the inner hole. Since the inner wall of the product is deep at different locations and there is interference on both sides, traditional machining methods are very difficult, resulting in low machine tool utilization and easy errors.

[0003] Existing technology CN220574770U includes an outer shank, a bottom of the tool body, and a top of the tool body. The outer shank is connected to one end of the bottom of the tool body, and the top of the tool body is connected to the other end of the bottom of the tool body. Four sets of insert grooves are formed on the outer sides of both the bottom and top of the tool body, with two insert grooves in each set. The first, second, third, and fourth inserts are respectively installed inside the four sets of insert grooves. The superior material and reasonable structure of the tool improve its toughness and stability, resulting in higher precision and better quality products. The replaceable insert tool significantly increases tool life, reduces the frequency of tool replacement, and increases machine tool utilization efficiency.

[0004] When cutting concentric circles of multiple sizes, multiple cutting tools generate a large amount of debris, which flies everywhere and can easily affect the operator's normal work, resulting in reduced processing efficiency. Utility Model Content

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] The first embodiment of this application is as follows:

[0023] Please see Figures 1-5 , Figure 1 This is a schematic diagram of the tool body of the first embodiment of the multi-size concentric circle high-efficiency cutting tool of this utility model. Figure 2 This is a schematic diagram of the mounting cylinder of the first embodiment of the multi-size concentric circle high-efficiency cutting tool of this utility model.

Figure 5 yes Figure 4 Enlarged view of point A in the middle.

[0024] This utility model provides a high-efficiency cutting tool for multi-size concentric circles, including a tool body 101, cutting blades 102, and a protective mechanism. The protective mechanism includes a mounting cylinder 104, a bearing 107, a mounting plate 108, multiple telescopic components, a fixing plate 112, a connecting component, a protective cover 113, and a locking block 106. The tool body 101 has a locking groove 103, and the mounting cylinder 104 has a mounting groove 105. The telescopic components include a long rod 109, a mounting block 111, and a telescopic spring 110. The connecting component includes a fixing ring 114 and four fixing kits. The fixing ring 114 has a fixing groove 115, and the fixing kits include bolts 116 and nuts 117. The aforementioned solution solves the problem that when cutting multi-size concentric circles, multiple cutting blades 102 generate a large amount of debris, which flies everywhere, easily affecting the operator's normal work and reducing processing efficiency.

[0025] In this specific embodiment, the blade 102 is fixedly connected to the blade body 101 and located on the outer side wall of the blade body 101. The locking block 106 is slidably connected to the mounting cylinder 104 and the blade body 101 and located within the mounting groove 105 and the locking groove 103. The inner side wall of the bearing 107 is slidably connected to the mounting cylinder 104, and the outer side wall of the bearing 107 is slidably connected to the mounting plate 108. Multiple telescopic components are disposed on the mounting plate 108 and the fixing plate 112, with the fixing plate 112 located below the mounting plate 108. The connecting component is disposed between the fixing plate 112 and the protective cover 113, with the protective cover 113 located below the fixing plate 112. The locking block 106 is then engaged in the locking groove 103. Within the mounting slot 105 and 03, the protective cover 113 is installed. When cutting concentric circles of multiple sizes, the cutter body 101 and the blade 102 rotate at high speed, and the mounting cylinder 104 rotates with the cutter body 101. Through the bearing 107, the mounting plate 108 does not rotate with the mounting cylinder 104. As the cutter body 101 and the blade 102 continue to enter the workpiece, the protective cover 113 contacts the workpiece. As the cutter body 101 penetrates deeper, the protective cover 113 remains stationary through multiple telescopic components, ensuring that the protective cover 113 does not affect the cutting of the cutter body 101 and the blade 102. The protective cover 113 blocks the chips generated during cutting, ensuring that the operator is not affected by the chips and can work normally, thus increasing processing efficiency.

[0026] The long rod 109 is slidably connected to the mounting plate 108 and passes through the mounting plate 108. The mounting block 111 is fixedly connected to one end of the long rod 109 and is located above the mounting plate 108. The two ends of the telescopic spring 110 are fixedly connected to the mounting block 111 and the mounting plate 108 respectively, and the long rod 109 is located inside the telescopic spring 110. When the cutter body 101 and the blade 102 enter the workpiece, after the lower end of the protective cover 113 contacts the workpiece, the cutter body 101 continues to enter the workpiece. The workpiece exerts a force on the protective cover 113, and the multiple long rods 109 move upward relative to the cutter body 101. The multiple telescopic springs 110 extend until the cutting is completed. Then, the cutter body 101 is pulled out of the workpiece, and the multiple telescopic springs 110 contract under the action of their own elastic potential energy, moving the protective cover 113 to its original position.

[0027] Secondly, the fixing ring 114 is fixedly connected to the fixing plate 112, one end of the protective cover 113 is slidably connected to the fixing ring 114 and located in the fixing groove 115, four fixing kits are set on the fixing ring 114 and the protective cover 113, the bolt 116 is threadedly connected to the fixing ring 114 and the protective cover 113, the nut 117 is threadedly connected to the bolt 116, and the plurality of nuts 117 and the plurality of bolts 116 fix the protective cover 113 in the fixing groove 115, ensuring that the protective cover 113 will not fall off the fixing plate 112 when the blade 102 is cutting, thus increasing the stability of the device.

[0028] When performing concentric circle cutting using this invention, the cutter body 101 and the blade 102 rotate at high speed, and the mounting cylinder 104 rotates with the cutter body 101. Through the bearing 107, the mounting plate 108 does not rotate with the mounting cylinder 104. When the cutter body 101 and the blade 102 enter the workpiece, after the lower end of the protective cover 113 contacts the workpiece, the cutter body 101 continues to enter the workpiece. The workpiece exerts a force on the protective cover 113, and the multiple long rods 109 move upward relative to the cutter body 101. The multiple telescopic springs 110 extend until the cutting is completed. Then, the cutter body 101 is pulled out of the workpiece, and the multiple telescopic springs 110 contract under the action of their own elastic potential energy, moving the protective cover 113 back to its original position. This ensures that the protective cover 113 does not affect the cutting of the cutter body 101 and the blade 102. The protective cover 113 blocks the chips generated during cutting, ensuring that the operator is not affected by the chips and can work normally, thus increasing processing efficiency.

[0029] The second embodiment of this application is as follows:

[0030] Please see Figure 6 , Figure 6 This is a schematic diagram of the overall structure of the second embodiment of the multi-size concentric circle high-efficiency cutting tool of this utility model. Based on the first embodiment, the multi-size concentric circle high-efficiency cutting tool of this embodiment also includes a fastening mechanism, which includes a fixing sleeve 202, an external thread 201 and an internal thread 203.

[0031] The external thread 201 is provided on the mounting cylinder 104, and the internal thread 203 is provided in the fixing sleeve 202. The internal thread 203 is threadedly connected to the external thread 201. When installing the protective cover 113, the locking block 106 is inserted into the locking groove 103 and the mounting groove 105, and the blade body 101 and the mounting cylinder 104 are connected. Then, the fixing sleeve 202 is rotated so that the fixing sleeve 202 and the mounting cylinder 104 are connected together through the internal thread 203 and the external thread 201, which strengthens the connection between the blade body 101 and the mounting cylinder 104 and increases the structural stability of the device.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
