Description

Woodworking milling cutter Technical Field

[0001] This application relates to the field of wood processing, and in particular to a woodworking milling cutter. Background Technology

[0002] Woodworking milling cutters are primarily used for milling wood and are core tools in wood processing, widely used in furniture manufacturing, architectural decoration, and wood product production. With the development of the woodworking industry, the demand for milling cutters continues to grow, especially against the backdrop of the rise of customized furniture and composite wood materials. The frequency of milling cutter use has further increased, and the efficiency and processing quality of milling cutters directly affect production efficiency and finished product quality.

[0003] Milling cutters are prone to wear during use, and this wear is often localized and unpredictable. Currently, most milling cutters use a one-piece design; once wear occurs in a certain area, the lack of effective local repair technology means the entire cutter must be scrapped. This "one-size-fits-all" scrapping model not only wastes resources but also significantly increases production costs for companies. Summary of the Invention

[0004] To reduce resource waste, this application provides a woodworking milling cutter.

[0005] The woodworking milling cutter provided in this application adopts the following technical solution:

[0006] A woodworking milling cutter includes a body, a blade, and a bolt. The outer wall of the body is provided with a connecting surface for the blade to abut against. The connecting surface is provided with a connecting groove. The blade is provided with a through opening. The bolt passes through the through opening and is threaded to the groove wall of the connecting groove.

[0007] By adopting the above technical solution, the blade and the main body are detachably connected by bolts, which makes it easy to replace the blade as needed and convenient for users. When the blade is worn, it can be replaced separately, reducing resource waste.

[0008] Preferably, there are multiple connecting slots, and the multiple connecting slots are spaced apart along the length direction of the main body.

[0009] By adopting the above technical solution, the position of the blade can be easily adjusted, making it convenient for users to use.

[0010] Preferably, a positioning block is fixedly connected to the connecting surface. The positioning block is located on the outer periphery of the connecting groove and is used for the blade to abut against it.

[0011] By adopting the above technical solution, the positioning block is used to position the blade, improve the efficiency of aligning the through-hole and the connecting groove, and improve assembly efficiency.

[0012] Preferably, the positioning block has a positioning groove at one end facing the connecting groove, and one wall of the positioning groove is coplanar with the connecting surface. The positioning groove is used for inserting the blade.

[0013] By adopting the above technical solution, the positioning groove limits the blade, improves the stability of the blade, makes the blade less prone to deformation and damage when subjected to force, extends the service life of the blade, and reduces resource waste.

[0014] Preferably, the outer wall of the main body is provided with a chip removal groove, which is located on the side of the connecting groove away from the positioning block, and the chip removal groove runs through the main body along the length of the main body.

[0015] By adopting the above technical solution, the chip discharge groove can discharge the chips generated by the cutting blade, thereby improving the material discharge efficiency.

[0016] Preferably, the main body includes a fixed column, a connecting block, and a pressure plate. A sliding column is fixedly connected to one end of the fixed column. The diameter of the sliding column is smaller than the diameter of the fixed column. The connecting block has a sliding opening that extends through the connecting block along its length. A connecting surface is provided on the connecting block. The sliding column is slidably connected to the inner wall of the sliding opening. A locking column is fixedly connected to the pressure plate. A locking groove is coaxially provided at the end of the sliding column opposite to the fixed column. The locking column is threadedly connected to the groove wall of the locking groove. The pressure plate abuts against the connecting block.

[0017] By adopting the above technical solution, the locking column and the sliding column are fixedly connected, and the pressure plate and the fixed column together clamp the connecting block. Connecting blocks of different heights can be replaced, which is suitable for different processing needs and is convenient for users.

[0018] Preferably, the inner wall of the sliding port is provided with a limiting groove, the limiting groove passes through the connecting block along the axial direction of the sliding port, and a limiting strip is fixedly connected to the outer wall of the sliding column, the limiting strip being slidably embedded in the limiting groove.

[0019] By adopting the above technical solution, the limiting strip is embedded in the limiting groove, which prevents the connecting block and the sliding column from rotating relative to each other, making it difficult for the blade to move, thereby improving the stability of the blade and improving the processing quality.

[0020] Preferably, it also includes a pad block, the pad block having a through-hole, the through-hole penetrating the pad block, and the sliding post passing through the through-hole.

[0021] By adopting the above technical solution, the height of the blade can be adjusted using a pad, which is suitable for different needs and convenient for users.

[0022] Preferably, the pad has a flow guiding surface at one end facing the connecting block, the flow guiding surface is located on the outer periphery of the connecting block, and the diameter of the flow guiding surface decreases as it approaches the connecting block.

[0023] By adopting the above technical solution, the flow guide surface reduces debris accumulation, facilitates chip removal, and improves chip removal efficiency.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The blade is detachably connected to the main body by bolts, which makes it easy to replace the blade as needed and convenient for users. When the blade is worn, it can be replaced individually, reducing resource waste.

[0026] 2. The positioning groove limits the blade, improves the stability of the blade, makes the blade less prone to deformation and damage under force, extends the service life of the blade, and reduces resource waste;

[0027] 3. The locking column and the sliding column are fixedly connected. The pressure plate and the fixed column together clamp the connecting block. The connecting blocks of different heights can be replaced to suit different processing needs and make it convenient for users. Attached Figure Description
