Description

Technical Field

[0001] This utility model belongs to the field of milling cutter technology, and particularly relates to a vertical shank end mill. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth sequentially and intermittently removes 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] For example, Chinese Patent Application No. 202420514613.6 discloses an end mill for slotting in the field of milling cutters. It includes a neck, a cutter body fixed to the upper surface of the neck, and first bottom cutting edges fixed to both sides of the upper surface of the cutter body. Second bottom cutting edges are fixed to the edge portions of the upper surface of the cutter body between the first bottom cutting edges. The surfaces of both the first and second bottom cutting edges are mirror-finished. Adjacent first and second bottom cutting edges are unequally spaced. A first bottom cutting edge bevel is formed on one side of each first bottom cutting edge, and a second bottom cutting edge bevel is formed on the side of each second bottom cutting edge away from the corresponding first bottom cutting edge bevel. In use, this four-flute milling cutter setup with two first bottom cutting edges and two second bottom cutting edges helps ensure efficient slotting of workpieces, avoids wear on the milling cutter during use, and extends the service life of the milling cutter, thus ensuring the quality of slotting of workpieces.

[0004] However, existing technologies have some problems: end mills usually use the cutter body to machine and cut objects. When cutting some objects, they need to be used manually. The cutter body of the end mill is inconvenient to hold, and it is difficult to hold the end mill to cut according to the usage situation, which reduces its practicality. Therefore, we propose a vertical shank end mill. Utility Model Content

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0024] like Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention provides a vertical shank end mill, including a cutter body 1, a mounting cylinder 2, and a fixing mechanism 3. A drive device 11 is fixedly connected to the upper end of the cutter body 1. The drive device 11 has a built-in drive motor. The output end of the drive device 11 is fixedly connected to the cutter body 1. A control switch 112 is connected to the outer wall of the drive device 11. The cutter body 1 is disposed inside the mounting cylinder 2, and the cutting end of the cutter body 1 extends to the outside of the mounting cylinder 2. A pressable pressure block 28 is connected to the outer wall of the mounting cylinder 2. The pressure block 28 extends into the mounting cylinder 2 and contacts the control switch 112. The fixing mechanism 3 is located at the upper end of the mounting cylinder 2. The fixing mechanism 3 is threadedly fixed to the mounting cylinder 2. The fixing mechanism 3 extends into the mounting cylinder 2 and contacts the drive device 11. By passing the cutter body 1 through the mounting cylinder 2, the fixing mechanism 3 seals the mounting cylinder 2, and the end of the fixing mechanism 3 extending into the mounting cylinder 2 limits and fixes the cutter body 1, making it convenient for handheld use of the end mill.

[0025] like Figure 2 and Figure 4 As shown, the mounting cylinder 2 has an internal cavity. The top of the mounting cylinder 2 has an inwardly recessed threaded hole 22, and the bottom of the mounting cylinder 2 has a through hole 23. Both the through hole 23 and the threaded hole 22 communicate with the internal cavity. The inner wall of the mounting cylinder 2 has multiple corresponding grooves 27, which communicate with the threaded hole 22 and the internal cavity, and are located at the upper end of the through hole 23. The outer wall of the mounting cylinder 2 has an anti-slip texture 21. The lower end of the mounting cylinder 2 is connected to a limiting cylinder 24, which is conical in shape. A limiting hole 241 is provided inside the limiting cylinder 24, corresponding to the through hole 23. The internal cavity of the mounting cylinder 2 facilitates the placement of the drive mechanism, and the limiting cylinder 24 allows the milling cutter body 1 to extend outwards through the limiting cylinder 24. The limiting cylinder 24 effectively limits the position of the milling cutter body 1, ensuring stability during use and facilitating cutting.

[0026] like Figure 5 As shown, a limiting piece 25 is fixedly connected inside the inner cavity, and a rubber pad 26 is fixedly connected inside the limiting piece 25. The rubber pad 26 extends into the through hole 23. The end face of the rubber pad 26 is provided with a central hole 261 and multiple slots 262. The slots 262 are located on the outer edge of the central hole 261 and are connected, and the slots 262 are arranged in a cross shape. When the milling cutter body 1 passes through the central hole 261 provided on the rubber pad 26, the milling cutter body 1 moves downward, causing the central hole 261 and the provided slots 262 to open, driving the inner wall of the rubber pad 26 to move downward, which facilitates the limiting and fixing of the milling cutter body 1 and improves the stability of the milling cutter body 1 and the mounting cylinder 2.

[0027] like Figure 2As shown, the mounting cylinder 2 is equipped with a spring 4 inside the inner cavity, and the spring 4 is set on the upper end of the driving device 11. The upper end of the spring 4 is in contact with the fixing mechanism 3. The spring 4 is provided to prevent the driving device 11 from contacting the fixing mechanism 3 and causing damage.

[0028] like Figure 3 As shown, the end of the milling cutter body 1 connected to the driving device 11 is provided with a connecting groove 12. The connecting groove 12 is used to accommodate the rubber pad 26. The end face of the connecting groove 12 is provided with multiple downward inclined surfaces 13. The outer wall of the driving device 11 is connected with multiple protrusions 111 that fit into the groove 27. The protrusions 111 provided on the driving device 11 facilitate the installation of the driving device 11 inside the mounting cylinder 2. The protrusions 111 extend into the groove 27 to limit the movement of the driving device 11.

[0029] like Figure 2 As shown, the fixing mechanism 3 includes a fixing shaft 31 extending into the inner cavity. The upper end of the fixing shaft 31 is connected to a threaded block 33 that is threadedly connected to the threaded hole 22. The upper end of the threaded block 33 is connected to a sealing cover 32 that seals the mounting cylinder 2. The lower end of the sealing cover 32 is connected to a sealing ring 321. The upper end of the sealing cover 32 is fixedly connected to a mounting block 34. A handle 35 is movably connected to the outer wall of the mounting block 34. By extending the fixing shaft 31 into the inner cavity and contacting the spring 4, rotating the sealing cover 32 causes the threaded block 33 to rotate inside the threaded hole 22, so that the threaded block 33 is threadedly connected to the inside of the mounting cylinder 2. During the threaded connection, the fixing shaft 31 moves into the inner cavity, which, in conjunction with the driving device 11, compresses the spring 4, preventing the fixing shaft 31 from directly contacting the driving device 11, thereby preventing damage to the driving device 11. Furthermore, the handle 35 facilitates the rotation of the sealing cover 32, making it convenient for the fixing mechanism 3 to be installed inside the mounting cylinder 2.

[0030] Working principle of Example 1:

[0031] When in use, first press the pressure block 28, which moves into the inner cavity and drives the control switch 112 on the drive device 11, thereby starting the drive motor inside the drive device 11 and driving the milling cutter body 1 to rotate. Then, hold it on the mounting cylinder 2 for easy use and cutting of objects. When it is necessary to remove the milling cutter body 1, simply turn the handle 35 to rotate the sealing cover 32, which will disassemble the fixing mechanism 3 from the mounting cylinder 2, thus making it easy to remove the milling cutter body 1.
