[0002] In addition to the main cutting edge on the circumferential surface, the three-sided end mill also has secondary cutting edges on both sides, thereby improving cutting conditions, increasing cutting efficiency, and reducing surface roughness. The three-sided end mill is mainly used for milling grooves of fixed dimensions, and can also be used to mill general grooves, stepped surfaces, and side surfaces. The three-sided end mill is fixed by an L-shaped mounting structure. However, the existing three-sided end mills using the L-shaped mounting structure cannot be quickly disassembled and assembled, and require the use of other tools. When damage occurs, it is inconvenient to maintain the three-sided end mill, affecting its use. Therefore, a three-sided end mill with an L-shaped mounting structure that can be quickly disassembled and assembled is proposed to solve the above-mentioned problems. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a quick-assembly and disassembly L-shaped holder structure for a three-sided end mill, which has the following advantages:

[0015] This quick-release three-sided milling cutter uses an L-shaped base structure. Through the setting of a fixing mechanism and a driving mechanism, it facilitates the installation and fixation of the cylinder and the milling cutter body. When the milling cutter needs to be removed, the operating handle is pulled down to move the moving plate. The moving plate drives the connecting plate, causing the two horizontal plates to move simultaneously. This causes the vertical plate and the round rod to move down simultaneously. The round rod presses against the wedge blocks on both sides, causing them to move relative to each other. The wedge blocks pull the rectangular plate, causing the clamping plate to move simultaneously. The movement of the rectangular plate stretches the fixing spring, thus releasing the clamping plate's restriction on the cylinder. The cylinder and the milling cutter body can be easily removed from the auxiliary cylinder, allowing for the installation of a new milling cutter body. After replacing the milling cutter, releasing the handle causes the moving plate, connecting plate, horizontal plate, and round rod to move back to their initial positions due to the elastic force of the return spring. The round rod releases its restriction on the wedge blocks, causing the fixing spring to push the rectangular plate and clamping plate back to their original positions, re-engaging them with the cylinder and completing the locking process. This achieves the purpose of quick disassembly and assembly. Attached Figure Description

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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a quick-assembly and disassembly L-shaped holder structure for a three-sided milling cutter, comprising a holder body 1 and a cylinder 3. An auxiliary cylinder 2 is fixedly installed on the outer side of the holder body 1, and the cylinder 3 is movably installed on the outer side of the auxiliary cylinder 2. A milling cutter body 4 is fixedly installed on the outer side of the cylinder 3. The milling cutter body 4 is the main cutting tool and is a three-sided milling cutter. A fixing mechanism 5 is provided on the inner side of the holder body 1, extending to its outer side and fitting against the cylinder 3. A driving mechanism 6 is provided on the inner side of the holder body 1, fitting against the fixing mechanism 5, and one end of the driving mechanism 6 extends to the outer side of the holder body 1.

[0024] The fixing mechanism 5 includes fixing springs 51. Two fixing springs 51 are fixedly installed on both the left and right sides of the inner wall of the seat body 1. The elastic coefficient of the fixing springs 51 can be set according to the requirements. A rectangular plate 52 is fixedly installed on one end of the fixing spring 51. Wedge blocks 53 are fixedly installed on the opposite sides of the rectangular plates 52 on the left and right sides. A clamping plate 54 extending to the outside of the seat body 1 is fixedly installed on the side of the rectangular plate 52 near the inner wall of the seat body 1. The upper and lower clamping plates 54 are respectively attached to the upper and lower sides of the cylinder 3. The clamping plates 54 are used to limit and fix the cylinder 3.

[0025] The inner wall of the base 1 has two perforations on each of the left and right sides. The size of the perforations is adapted to the card plate 54. The perforations are used for the card plate 54 to extend. The interior of the base 1 is hollow. The hollow design is used to install the height mechanism 5 and the drive mechanism 6. The wedge block 53 is inclined on the side near the rectangular plate 52 to facilitate movement in cooperation with the round rod 66.

[0026] The drive mechanism 6 includes a movable plate 61. The movable plate 61, extending to the right side of the seat 1, is slidably installed on the left side of the inner wall of the seat 1. A handle 62 is fixedly installed on the right side of the movable plate 61. A connecting plate 63 is fixedly installed on the top of the movable plate 61. Two horizontal plates 64 are fixedly installed on the outer side of the connecting plate 63. The connecting plate 63 connects the two horizontal plates 64 to ensure synchronous movement. Vertical plates 65 are fixedly installed at both the front and rear ends of the top of the horizontal plate 64. Two round rods 66 are fixedly installed between the front and rear vertical plates 65. The round rods 66 are in contact with the top of the wedge block 53. A support cylinder 67 is fixedly installed on the top of the top horizontal plate 64. A support rod 68, extending to the top and fixedly connected to the inner top wall of the seat 1, is slidably installed on the inner side of the support cylinder 67. A return spring 69, sleeved on the outer side of the support cylinder 67 and the support rod 68, is fixedly installed between the inner top wall of the seat 1 and the top horizontal plate 64. The elastic coefficient of the return spring 69 can be set according to requirements.

[0027] Throughout the process, the milling cutter 4 can be quickly assembled and disassembled by operating the handle 62 without the need for tools, thus improving work efficiency and safety.

[0028] The inner wall of the seat 1 has a slotted hole on the right side. The size of the slotted hole is adapted to the movement trajectory of the moving plate 61. The moving plate 61 is slidably connected to the inner wall of the slotted hole. The inner top wall of the support cylinder 67 has a round hole adapted to the support rod 68. The slotted hole is used for the sliding of the moving plate 61. The outer side of the handle 62 is covered with a sponge sleeve, which provides a comfortable grip and facilitates user operation.

[0029] In use, the base 1 is the basic part of the structure. The milling cutter body 4 is installed on the machine body through the base 1, and then the cutting operation is carried out.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] In summary, this quick-assembly and disassembly three-sided milling cutter with an L-shaped base structure, through the setting of a fixing mechanism 5 and a driving mechanism 6, facilitates the installation and fixation of the cylinder 3 and the milling cutter body 4. When it is necessary to disassemble the milling cutter 4, the operating handle 62 pulls down the moving plate 61, which in turn moves the connecting plate 63, causing the two horizontal plates 64 to move simultaneously. This causes the vertical plate 65 and the round rod 66 to move down simultaneously. The round rod 66 presses against the wedge blocks 53 on both sides, causing them to move relative to each other. The wedge blocks 53 pull the rectangular plate 52, causing the clamping plate 54 to move simultaneously. The movement of the rectangular plate 52 stretches the fixing spring 51, thus releasing the clamping plate 54 from limiting the cylinder 3. The cylinder 3 and the milling cutter body can then be easily disassembled. 4. Remove from auxiliary cylinder 2 and install new milling cutter body 4. After replacing the new milling cutter 4, release handle 62. Due to the elastic force of return spring 69, moving plate 61, connecting plate 63, horizontal plate 64 and round rod 66 will move back to their initial positions. Round rod 66 will release the limit on wedge block 53, so that fixed spring 51 will push rectangular plate 52 and clamping plate 54 to reset and re-fit with cylinder 3 to complete locking. This achieves the purpose of quick disassembly and assembly, and solves the problem that the existing three-sided milling cutter L-shaped structure cannot be quickly disassembled and assembled, and other tools are required. When damage occurs, it is inconvenient to maintain the three-sided milling cutter, which affects the use of the three-sided milling cutter.
