Description

Technical Field

[0001] This application relates to the field of milling cutter heads, and more specifically, to a milling cutter head. Background Technology

[0002] When machining mechanical parts, milling cutters are often used on the corresponding machine tools to machine the surface of the parts in order to ensure the accuracy of the machined surface. As a tool for machining relatively wide flat surfaces, the milling cutter usually has multiple tools mounted on the cutter body to achieve the milling of a large diameter surface in one pass.

[0003] Traditional blades are evenly distributed on the blade disc with equal lengths, and the height of multiple blades is the same, which limits the height of the blades. If a taller blade is used at once, this problem can be overcome, but the production cost of taller blades is also higher.

[0004] A milling cutter disc is now provided. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a milling cutter disc, comprising: a disc body; a mounting hole formed on the disc body; a first threaded hole formed on the disc body; a mounting groove formed on the disc body; an insert movably disposed on the mounting groove; a fixing hole formed on the insert; a second threaded hole formed on the disc body; and a Torx screw passing through the fixing hole and threadedly connected to the second threaded hole; wherein, multiple mounting grooves, inserts, and Torx screws are provided, and are evenly distributed circumferentially on the mounting grooves; the height of the multiple mounting grooves rises and falls sequentially in a clockwise or counterclockwise direction along the periphery of the disc body.

[0007] By incorporating Torx screws and mounting slots, the blade is placed in the mounting slot during installation. The Torx screw is then passed through the fixing hole and threaded into the second threaded hole, thus installing the blade. The Torx screws and mounting slots facilitate easy removal and installation of the blade, allowing for the replacement of blades of the appropriate size according to the required dimensions of the product, avoiding the need to replace the entire disc and improving work efficiency. The height of the multiple mounting slots rises and falls sequentially clockwise or counterclockwise along the outer perimeter of the disc. Multiple blades of varying heights can be combined with multiple blades of varying heights, with the top of the lower blade positioned between the top and bottom wall of the upper blade, resulting in a higher combined height. Combining blades of different heights allows for greater flexibility in machining dimensions, improving practicality. During installation, the mounting hole is inserted into the tool holder of the machining center, and the upper limit block of the tool holder engages with the limit slot to provide a limiting function. Finally, the tool disc is fixed to the tool holder using external fixing bolts.

[0008] In some implementations, a limiting groove is formed on the inner wall of the mounting hole, and the limiting groove extends through the disc body.

[0009] In some implementations, the limiting groove is square.

[0010] In some implementations, multiple first threaded holes are provided and are evenly distributed circumferentially on the disk body.

[0011] In some implementations, the first threaded hole is disposed between the mounting hole and the periphery of the disc body.

[0012] In some implementations, the second threaded hole penetrates the disc body.

[0013] In some implementations, the blade is made of cemented carbide.

[0014] In some implementations, the mounting hole is circular.

[0015] The beneficial effects of this application are as follows:

[0016] By setting multiple mounting slots that rise and fall sequentially in a clockwise or counterclockwise direction along the outer perimeter of the disc, multiple taller blades and multiple shorter blades are combined together. The top of the lower blade is positioned between the top and bottom wall of the upper blade, resulting in a higher combined height. This allows for the machining of deeper milling holes, improving practicality and avoiding the use of taller blades that would affect costs. It also facilitates the removal and installation of blades, allowing for the replacement of blades of the appropriate size according to the required dimensions of the product, avoiding the need to replace the entire disc and improving work efficiency.

[0033] Reference Figure 1-6 A milling cutter disc includes: a disc body 1, a mounting hole 7, a first threaded hole 2, a mounting groove 5, an insert 3, a fixing hole 9, a second threaded hole 8, and a Torx screw 4. The mounting hole 7 is circular and is located on the disc body 1. The first threaded hole 2 is also circular. The mounting groove 5 is located on the disc body 1. The insert 3 is movably mounted on the mounting groove 5. The fixing hole 9 is located on the insert 3. The second threaded hole 8 is located on the disc body 1. The Torx screw 4 passes through the fixing hole 9 and is threadedly connected to the second threaded hole 8. The second threaded hole 8 penetrates the disc body 1. Multiple mounting grooves 5, inserts 3, and Torx screws 4 are provided and are evenly distributed circumferentially on the mounting grooves 5. The height of the multiple mounting grooves 5 increases or decreases sequentially in a clockwise or counterclockwise direction along the outer periphery of the disc body 1. A limiting groove 6 is formed on the inner wall of the mounting hole 7 and penetrates the disc body 1. The limiting groove 6 is square and serves as a limiting and guiding groove. Multiple first threaded holes 2 are provided and are evenly distributed circumferentially on the disc body 1. The first threaded holes 2 are located between the mounting hole 7 and the outer periphery of the disc body 1. During installation, the disc body 1 is mounted on the machining center tool holder, and then connected to the first threaded holes 2 by fixing bolts, and the fixing bolts are also threaded to the corresponding positions on the machining center tool holder.

[0034] The blade 3 is made of cemented carbide, which has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500℃, and it still has a high hardness at 1000℃.

[0035] Working process: By setting up Torx screws 4 and mounting slots 5, during installation, the blade 3 is placed in the mounting slot 5, and Torx screws 4 are passed through the fixing hole 9. Then, the Torx screws 4 are threaded into the second threaded hole 8, thus installing the blade 3. The Torx screws 4 and mounting slots 5 facilitate the disassembly and installation of the blade 3, allowing the blade 3 to be replaced according to the required size of the corresponding product, avoiding the need to replace the entire disc 1, thus improving work efficiency. The height of the multiple mounting slots 5 rises and falls sequentially in a clockwise or counterclockwise direction along the outer perimeter of the disc 1. Multiple blades 3 with higher heights and multiple blades 3 with lower heights are combined together, and the top of the lower blade 3 is located between the top and bottom wall of the upper blade 3. The height formed by the combination of two blades 3 is even higher. Different heights of blades 3 can also be combined, making the machinable size more flexible and improving practicality. During installation, the mounting hole 7 is installed on the tool holder of the machining center, and the cooperation between the upper limit block of the tool holder and the limit slot 6 plays a limiting role. Then, the tool disc is fixedly installed on the tool holder by external fixing bolts.
