Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, specifically, it relates to a milling cutter disc that facilitates the replacement of milling cutters. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more milling cutters used for milling operations. During operation, each milling cutter cuts off the excess material from the workpiece in turn. It is widely used in the processing of various metal and non-metal materials.

[0003] In actual machining processes, due to different machining requirements, it is necessary to frequently replace the milling cutters on the milling cutter head. Traditional milling cutters typically use bolts to fix the milling cutters to the cutter head. The milling cutters are installed on the cutter head one by one by bolting. Since there are usually multiple milling cutters, the cutter head needs to be disassembled by tightening the bolts one by one during disassembly, which is a time-consuming and labor-intensive process.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To address the risk of hand injuries when holding the milling cutter by hand for fixation, the basic concept of this utility model is as follows:

[0006] A milling cutter disc for easy cutter replacement includes a disc body and milling cutter inserts. The disc body has equidistantly distributed mounting slots around its perimeter. Each milling cutter insert is housed within one of these slots. A through hole is formed in the center of each milling cutter insert, and a rod is installed inside the through hole. A connecting slot is formed on one side of each mounting slot, and the rod is inserted into the connecting slot. A positioning hole is formed on the rod. The bottom of the disc body has equidistantly distributed movable slots that penetrate the connecting slot. A positioning rod is slidably mounted on the inner wall of each movable slot and inserted into the positioning hole. A base plate is provided at the bottom of the disc body, and equidistantly distributed sliding holes are formed on the base plate. The positioning rod is slidably mounted on the inner wall of each sliding hole, and a threaded section is provided at the bottom end of the positioning rod. A fastening nut is screwed onto the outer wall of the threaded section.

[0007] In a preferred embodiment of this utility model, the top of the fastening nut contacts the outer wall of the bottom of the base plate.

[0008] In a preferred embodiment of this utility model, the sliding hole communicates with the movable groove, and guide grooves are provided on the inner walls of both the sliding hole and the movable groove.

[0009] In a preferred embodiment of this utility model, a guide strip is fixedly connected to the outer wall of the positioning rod, and the guide strip is slidably connected to the inner wall of the guide groove.

[0010] In a preferred embodiment of this utility model, the base plate has symmetrically arranged movable holes, and the inner side of the movable holes is provided with fixing bolts.

[0011] In a preferred embodiment of this utility model, the bottom of the milling cutter body is provided with symmetrically arranged threaded holes, and the fixing bolts are screwed into the threaded holes.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention, through its base plate, insert rod, connecting groove, movable groove, positioning rod, threaded section, fastening nut, and positioning hole, allows multiple milling cutters to be simultaneously fixed on the milling cutter head body after initial positioning, thus improving installation efficiency. When the milling cutter needs to be replaced, the positioning rod is moved to release the positioning of the insert rod, and then the milling cutter is removed from the mounting groove. After disassembly, a suitable milling cutter can be selected for replacement according to different processing requirements, improving disassembly efficiency and making the process of replacing multiple milling cutters simultaneously time-saving and labor-saving. If a single milling cutter needs to be replaced due to wear, the fastening nut can be rotated to disengage from the threaded section, releasing the positioning rod's limitation. Then, the positioning rod is pulled to move out of the positioning hole, releasing the positioning of the insert rod. Finally, the milling cutter is moved to move the insert rod out of the connecting groove, allowing the milling cutter to be disassembled and replaced individually.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 8 As shown, a milling cutter disc for easy cutter replacement includes a milling cutter disc body 1 and milling cutter inserts 2. The milling cutter disc body 1 has equidistantly distributed mounting grooves 3 around its perimeter. The milling cutter inserts 2 are disposed within the mounting grooves 3. A through hole is formed in the center of the milling cutter insert 2, and a rod 7 is installed inside the through hole. A connecting groove 8 is formed on one side of the mounting grooves 3, and the rod 7 is inserted into the connecting groove 8. A positioning hole 14 is formed on the rod 7. Equidistantly distributed movable grooves 9 are formed at the bottom of the milling cutter disc body 1, and the movable grooves 9 and connecting grooves 8 are connected through each other. A positioning rod 10 is slidably disposed on the inner wall of the movable groove 9 and is inserted into the positioning hole 14. A base plate 4 is provided at the bottom of the milling cutter disc body 1, and symmetrically arranged movable holes are formed on the base plate 4. A fixing bolt 5 is provided inside the movable holes. Symmetrically arranged threaded holes 6 are formed at the bottom of the milling cutter disc body 1, and the fixing bolts 5 are screwed into the threaded holes 6.

[0027] The base plate 4 has equidistantly distributed sliding holes 15. The positioning rod 10 is slidably disposed on the inner wall of the sliding hole 15. The sliding hole 15 communicates with the movable groove 9. Guide grooves 16 are provided on the inner walls of both the sliding hole 15 and the movable groove 9. A guide strip 13 is fixedly connected to the outer wall of the positioning rod 10. The guide strip 13 is slidably connected to the inner wall of the guide groove 16. Multiple milling cutters 2 are placed in the mounting groove 3 for positioning, so that the detachable insert rod 7 on the milling cutter 2 is inserted into the connecting groove 8. After placement, the base plate 4 is moved towards the bottom of the milling cutter body 1, so that the base plate 4 drives the positioning rod 10 to move in the movable groove 9 until the positioning rod 10 is inserted into the positioning hole 14, forming an insertion. The positioning function of rod 7 positions the milling cutter 2, while the base plate 4 contacts the bottom outer wall of the milling cutter body 1. Then, the fixing bolt 5 is screwed into the threaded hole 6 to achieve a fixed connection between the base plate 4 and the milling cutter body 1, thus completing the fixed installation of the milling cutter 2. When it is necessary to disassemble the milling cutter 2, the fixing bolt 5 is unscrewed from the threaded hole 6. After unscrewing, the base plate 4 is pulled to move, causing the base plate 4 to move the positioning rod 10 until the positioning rod 10 is moved out of the positioning hole 14. Then, the milling cutter 2 can be removed from the mounting slot 3. After disassembly, the appropriate milling cutter 2 can be selected and replaced according to different processing requirements.

[0028] In a specific embodiment, the bottom end of the positioning rod 10 is provided with a threaded section 11, and a fastening nut 12 is screwed onto the outer wall of the threaded section 11.

After placement, the base plate 4 is moved towards the bottom of the milling cutter body 1, so that the base plate 4 drives the positioning rod 10 to move in the movable slot 9 until the positioning rod 10 is inserted into the positioning hole 14, forming a positioning effect on the insert rod 7, so that the milling cutter insert 2 is positioned. At the same time, the base plate 4 contacts the bottom outer wall of the milling cutter body 1. Then, the fixing bolt 5 is screwed into the threaded hole 6 to realize the fixed connection between the base plate 4 and the milling cutter body 1, thus completing the fixed installation of the milling cutter insert 2. When it is necessary to disassemble the milling cutter insert 2;

[0031] Unscrew the fixing bolt 5 from the threaded hole 6. After unscrewing, pull the base plate 4 to move it, causing the base plate 4 to move the positioning rod 10 until the positioning rod 10 moves out of the positioning hole 14. Then, the milling cutter 2 can be removed from the mounting slot 3. After disassembly, select the appropriate milling cutter 2 to replace it according to different processing requirements. When the milling cutter 2 is worn and needs to be replaced, turn the fastening nut 12 to disengage it from the threaded section 11, releasing the positioning rod 10 from its limit. Then, pull the positioning rod 10 to move it out of the positioning hole 14, releasing the positioning of the insert rod 7. Then, move the milling cutter 2 so that the insert rod 7 moves out of the connecting slot 8, allowing the milling cutter 2 to be disassembled and replaced individually.
