Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, specifically to an adjustable under-mounted double-edged milling cutter. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. Undercut milling cutters are commonly used tools in machining. They are mounted on a tool holder via an undercut method, ensuring a stable connection and stability during high-speed rotary cutting. They come in various cutting edge configurations, including double-edged and multi-edged types, allowing for selection based on specific needs. Undercut milling cutters are typically made of high-speed steel or cemented carbide, making them suitable for a wide range of workpiece materials. They have a broad application range, suitable for plane milling, contour milling, and slot milling, effectively improving machining efficiency and ensuring machining accuracy.

[0003] The key feature of a conventional undercut double-flute end mill is its two cutting edges, typically located on opposite sides of the cutter. These edges are used to perform cutting operations such as material removal during milling. However, there are also end mills with cutting edges on multiple faces, such as three-flute and four-flute cutters, which can also be mounted on a tool holder using an undercut mounting method.

[0004] Existing undercut milling cutters have a fixed structure that cannot be changed during use. When workers need to process workpieces, they need to temporarily replace and install specific milling cutters to meet different operational needs, which is inconvenient for workers.

[0029] This utility model provides a technical solution: Example

[0030] Combination Figures 1 to 4 An easily adjustable under-mounted double-edged milling cutter includes a milling cutter body 3, a milling cutter mounting shank 31 fixedly connected to the bottom of the milling cutter body 3, a connecting rod 32 fixedly connected to the top of the milling cutter body 3, a mounting mechanism 1 provided on the outside of the connecting rod 32, and an adjustment mechanism 2 provided on the outside of the mounting mechanism 1.

[0031] The mounting mechanism 1 includes a connecting component 11 and a mounting component 12. The connecting component 11 is disposed on the outer ring of the connecting rod 32, and the mounting component 12 is disposed on the outside of the connecting component 11.

[0032] The connecting assembly 11 includes a sleeve 1101, which is fitted onto the top of the outer ring of the end mill body 3. A sleeve bracket 1102 is fixedly connected to the top of the sleeve 1101, and the sleeve bracket 1102 is fitted onto the outside of the connecting rod 32. The mounting assembly 12 includes a threaded rod 1201, which is fixedly connected to the outer ring of the end mill body 3. The threaded rods 1201 are arranged in three evenly spaced positions on the outer ring of the end mill body 3. The threaded rods 1201 are snapped into the bottom of the sleeve 1101. 1. A fixing seat 1202 is sleeved on the outer ring. The fixing seat 1202 is fixedly connected to the outer ring of the sleeve frame 1101. The bottom of the fixing seat 1202 has a groove corresponding to the position of the threaded rod 1201. An insert ring 1203 is sleeved on the outer ring of the threaded rod 1201. The insert ring 1203 is snapped into the inner side of the outer side of the fixing seat 1202. A nut 1204 is provided on the outer side of the insert ring 1203. The nut 1204 is threadedly connected to the outer ring of the threaded rod 1201. The inner side of the nut 1204 fits against the outer side of the insert ring 1203.

[0033] Furthermore, workers only need to rotate nut 1204 to complete or release the fixing and disassembly between sleeve 1101 and milling cutter body 3. The operation is simple and convenient for workers to use. It is convenient for workers to disassemble and assemble the sleeve 1101 as a whole, and to replace or repair the sleeve 1101. When the sleeve 1101 or sleeve frame 1102 and other structures are damaged, it will not affect the use of the milling cutter as a whole, thus ensuring the working efficiency of the milling cutter and making it convenient for workers to use. Example

[0034] See Figures 1 to 6 Furthermore, based on Embodiment 1, the positioning mechanism 2 includes an assembly component 21, a positioning component 22, and a fixing component 23. The assembly component 21 is disposed outside the connecting component 11, the positioning component 22 is disposed inside the assembly component 21, and the fixing component 23 is disposed inside the positioning component 22.

[0035] Assembling component 21 includes mounting bracket 2101, which is fixedly connected to the outside of sleeve 1102 and to the top of sleeve frame 1101. A retainer 2102 is sleeved on the outside of mounting bracket 2101, and a cutting tool 2103 is fixedly connected to the outside of retainer 2102. Positioning component 22 includes a protrusion 2201, which is fixedly connected inside retainer 2102 and engages with mounting bracket 2101. A retaining strip 2202 is fixedly connected inside protrusion 2201 and engages with mounting bracket 2101. Fixing component 23 includes a slip ring 2301. 301 is slidably connected to the left and right sides inside the clip 2202. The inner ring of the slip ring 2301 is fixedly connected to the threaded cylinder 2302. The threaded cylinder 2302 is slidably connected to the left and right sides inside the clip 2202. The outer side of the slip ring 2301 is fixedly connected to the compression spring 2303. The compression spring 2303 is sleeved on the outer ring of the threaded cylinder 2302. The compression spring 2303 is fixedly connected to the left and right sides inside the clip 2202. The threaded cylinder 2302 passes through the clip 2202 and is snapped into the left and right sides inside the mounting bracket 2101. The inner ring of the threaded cylinder 2302 is threadedly connected to the bolt 2304. The bolt 2304 is sleeved on the left and right sides inside the bracket 2102.

[0036] Furthermore: the slip ring 2301 is slidably connected inside the retaining strip 2202 and cannot rotate, so that when the threaded cylinder 2302 is in contact with the bolt 2304, it can only move inward and outward with the rotation of the bolt 2304, so that the threaded cylinder 2302 can be moved outward by the installation of the bolt 2304 and locked inside the mounting bracket 2101 to complete the installation of the cutting tool 2103.

[0037] In actual operation, when this device is in use, when the sleeve 1102 needs to be installed, the operator first puts the sleeve frame 1101 and the sleeve 1102 on the outside of the milling cutter body 3 and the connecting rod 32 from top to bottom, so that the top of the inner part of the sleeve frame 1101 is in contact with the top of the milling cutter body 3. At this time, the threaded rod 1201 is engaged in the bottom of the sleeve frame 1101. Then the operator engages the multiple insert rings 1203 on the outside of the fixed seat 1202, so that the insert rings 1203 are sleeved on the outer ring of the threaded rod 1201. Finally, the operator rotates the nut 1204 to install it on the outer ring of the threaded rod 1201 until the inner side of the nut 1204 is in contact with the outer side of the insert ring 1203 and cannot move. At this time, the installation of the entire structure of the sleeve 1102 is completed.

[0038] When the cutting tool 2103 needs to be installed, the operator first clamps the holder 2102 onto the outside of one of the multiple mounting brackets 2101 from top to bottom. At the same time, the protrusion 2201 and the retaining strip 2202 are simultaneously engaged inside the mounting bracket 2101. Then, the operator moves the mounting bracket 2101 downwards until the cutting tool 2103 is moved to the appropriate position and the threaded cylinder 2302 is aligned with the outer groove of the mounting bracket 2101. Finally, the operator inserts the bolt 2304 into the mounting bracket 2101. The bolt 2304 is inserted into the hole corresponding to the threaded cylinder 2302, so that the bolt 2304 contacts the threaded cylinder 2302. Then, the bolt 2304 is rotated. At this time, the bolt 2304 rotates and contacts the threaded cylinder 2302, causing the threaded cylinder 2302 to move outward from the outer ring of the bolt 2304. The threaded cylinder 2302 moves outward and passes through the retaining strip 2202 and is engaged with the inner side of the mounting bracket 2101. Then, the operator repeats the above operation to complete the installation of the multiple bolts 2304 on both sides of the bracket 2102. At this time, the installation of the cutting tool 2103 is completed.
