[0001] This utility model relates to the field of milling cutter head technology, specifically a milling cutter head that is easy to assemble and disassemble. Background Technology

[0002] A milling cutter head, also known as a milling cutter disc, is an accessory used on CNC milling machines. It is mainly used for cutting and machining the surface of workpieces. The core component of the milling cutter head is a number of milling cutters mounted on it. These milling cutters can be cylindrical, faceted, or other special-shaped tools.

[0003] In traditional milling cutter head and tool holder connection structures, special tools are often required for disassembly and assembly, which is cumbersome and affects the continuity of the entire production process, greatly reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a milling cutter head that is easy to assemble and disassemble, solving the problem that the traditional connection structure between the milling cutter head and the tool holder often requires special tools for disassembly and assembly, which is cumbersome and affects the continuity of the entire production process, greatly reducing work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a conveniently detachable milling cutter disc, comprising a milling cutter disc and a tool holder. The upper surface of the milling cutter disc has two limiting grooves. One end of the tool holder is fixedly fitted with two limiting blocks, which are internally connected to the limiting grooves. The tool holder has two receiving grooves, each containing a locking mechanism. A positioning rod is inserted into the milling cutter disc and then into the tool holder. The outer surface of the positioning rod has two positioning grooves, and the insertion ends of the locking mechanisms are inserted into the positioning grooves.

[0007] Furthermore, the snap-fit ​​mechanism includes a mounting plate disposed inside the receiving groove, and a spring is fixedly mounted on one side of the mounting plate, with one end of the spring fixedly connected to the inside of the receiving groove.

[0008] Furthermore, a limiting rod is fixedly installed on one side of the mounting plate, the limiting rod extends to the outer surface of the tool holder, and a pull rod is fixedly installed at one end of the limiting rod.

[0009] Furthermore, a plug rod is fixedly installed on the side of the mounting plate away from the limiting rod, and the plug rod extends into the interior of the tool holder and is inserted into the positioning groove.

[0010] Furthermore, the milling cutter disc has mounting slots inside, and the number of mounting slots is fixed at two.

[0011] Furthermore, magnets are fixedly installed inside each of the mounting slots.

[0012] Furthermore, the upper surface of the magnet and the lower surface of the knife handle are magnetically attracted to each other.

[0013] This utility model has the following beneficial effects:

[0014] (1) By pulling the pull rods on the two sets of locking mechanisms, the pull rods drive the insert rod to move out of the inside of the tool holder through the limiting rod and the mounting plate. At the same time, the spring is squeezed and compressed by the mounting plate, so that the positioning rod can be inserted into the inside of the tool holder through the milling cutter disc. When the positioning groove and the insert rod coincide, the pull on the pull rod is released, so that the spring rebounds and the spring resets the spring and the insert rod, so that the insert rod is inserted into the inside of the positioning groove, thus connecting the tool holder and the milling cutter disc together and completing the installation. When disassembly is required, the operation of the above-mentioned locking mechanism is reversed, so that the locking mechanism releases the limiting of the positioning rod, and then the positioning rod is pulled out from the inside of the milling cutter disc and the tool holder, so that the milling cutter disc and the tool holder can be disassembled. This achieves the effect of easy disassembly and assembly, avoids the situation that special tools are needed to disassemble the milling cutter disc and the tool holder, and improves the efficiency of disassembly and assembly.

[0015] (2) The magnets in the two mounting slots inside the milling cutter disc of this utility model are magnetically attracted to the lower surface of the tool holder, which further enhances the stability of the connection between the milling cutter disc and the tool holder, and also facilitates the initial positioning of the milling cutter disc and the tool holder, further improving the ease of installation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-6 As shown, this utility model is a conveniently disassembled milling cutter disc, including a milling cutter disc 1 and a tool holder 2. The upper surface of the milling cutter disc 1 is provided with a limiting groove 101, and the number of limiting grooves 101 is fixed to two. One end of the tool holder 2 is fixedly installed with a limiting block 202, and the number of limiting blocks 202 is fixed to two. The limiting blocks 202 and the limiting grooves 101 are inserted into each other. The inside of the tool holder 2 is provided with a receiving groove 201, and the number of receiving grooves 201 is fixed to two. The receiving grooves 201 are each installed with a snap-fit ​​mechanism 3. A positioning rod 4 is inserted into the inside of the milling cutter disc 1. The positioning rod 4 is inserted into the inside of the tool holder 2 through the inside of the milling cutter disc 1. The outer surface of the positioning rod 4 is provided with a positioning groove 401, and the number of positioning grooves 401 is fixed to two. The insertion end of the snap-fit ​​mechanism 3 is inserted into the inside of the positioning groove 401.

[0028] The snap-fit ​​mechanism 3 includes a mounting plate 301, which is disposed inside the receiving groove 201. A spring 302 is fixedly mounted on one side of the mounting plate 301, and one end of the spring 302 is fixedly connected to the inside of the receiving groove 201.

[0029] A limiting rod 303 is fixedly installed on one side of the mounting plate 301. The limiting rod 303 extends to the outer surface of the tool holder 2, and a pull rod 304 is fixedly installed on one end of the limiting rod 303.

[0030] A plug rod 305 is fixedly installed on the side of the mounting plate 301 away from the limiting rod 303. The plug rod 305 extends into the inside of the tool holder 2 and is inserted into the positioning groove 401.

[0031] By pulling the pull rods 304 on the two sets of locking mechanisms 3, the pull rods 304 drive the insertion rod 305 out of the tool holder 2 through the limit rod 303 and the mounting plate 301. At the same time, the spring 302 is compressed by the mounting plate 301, so that the positioning rod 4 can be inserted into the tool holder 2 through the milling cutter disc 1. When the positioning groove 401 and the insertion rod 305 coincide, the pull on the pull rod 304 is released, so that the spring 302 rebounds. The spring 302 resets the spring 302 and the insertion rod 305, thereby allowing the insertion rod 4 to be inserted into the tool holder 2. The rod 305 is inserted into the positioning groove 401 to connect the tool holder 2 and the milling cutter disc 1 together, completing the installation. When disassembly is required, the operation of the above-mentioned locking mechanism 3 is reversed to release the locking mechanism 3 from the limiting position of the positioning rod 4. Then, the positioning rod 4 is pulled out from the inside of the milling cutter disc 1 and the tool holder 2, and the milling cutter disc 1 and the tool holder 2 can be disassembled. This achieves the effect of easy disassembly and assembly, avoiding the need for special tools to disassemble the milling cutter disc 1 and the tool holder 2, and improving the efficiency of disassembly and assembly.

[0032] The milling cutter disc 1 has two mounting slots 102 inside.

[0033] Magnets 5 are fixedly installed inside the mounting slots 102;

[0034] The upper surface of magnet 5 and the lower surface of knife handle 2 are magnetically attracted to each other;

[0035] The magnets 5 in the two mounting slots 102 inside the milling cutter disc 1 are magnetically attracted to the lower surface of the tool holder 2, which further enhances the stability of the connection between the milling cutter disc 1 and the tool holder 2, and also facilitates the initial positioning of the milling cutter disc 1 and the tool holder 2, further improving the ease of installation.

[0036] In use, first, align the two limiting blocks 202 at one end of the tool holder 2 with the two limiting grooves 101 on the upper surface of the milling cutter disc 1 and insert them. At this time, the milling cutter disc 1 and the tool holder 2 are initially positioned. Then, by pulling the pull rods 304 on the two sets of locking mechanisms 3, the pull rods 304 drive the insertion rod 305 out of the inside of the tool holder 2 through the limiting rods 303 and the mounting plate 301. At the same time, the spring 302 is compressed by the mounting plate 301, so that the positioning rod 4 can be inserted into the inside of the tool holder 2 through the milling cutter disc 1. When the positioning groove 401 and the insertion rod 305 coincide, release the pull of the pull rod 304, and the tool holder 2 can be inserted into the inside of the tool holder 2. Spring 302 rebounds, resetting spring 302 and insert rod 305, allowing insert rod 305 to be inserted into the positioning groove 401, thus connecting tool holder 2 and milling cutter disc 1 together and completing the installation. When disassembly is required, the operation of the above-mentioned locking mechanism 3 is reversed, which releases the locking mechanism 3 from the limiting position of positioning rod 4. Then, positioning rod 4 is pulled out from the inside of milling cutter disc 1 and tool holder 2, thus completing the disassembly of milling cutter disc 1 and tool holder 2. This achieves the effect of easy disassembly and assembly, avoiding the need for special tools to disassemble milling cutter disc 1 and tool holder 2, and improving disassembly and assembly efficiency.

[0037] The magnets 5 in the two mounting slots 102 inside the milling cutter disc 1 are magnetically attracted to the lower surface of the tool holder 2, which further enhances the stability of the connection between the milling cutter disc 1 and the tool holder 2, and also facilitates the initial positioning of the milling cutter disc 1 and the tool holder 2, further improving the ease of installation.
