Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a single-sided side milling forming cutter. Background Art

[0002] The sides of the mobile phone casing are usually designed to be smooth arc-shaped for aesthetics, while the back of the mobile phone casing is a smooth plane. Therefore, after the mobile phone casing is formed, its sides and back need to be processed into high-finish surfaces, which requires different milling cutters to process.

[0003] During the use of the existing side milling cutter, the side milling cutter will cause serious wear under high-intensity work. After working for a long time, the milling cutter blade will become blunt and need to be replaced. The milling cutter blade and the cutter rod are generally designed as an integrated structure. When replacing, the entire milling cutter needs to be replaced, resulting in material waste. Therefore, we have launched a new single-sided side milling cutter. Utility Model Content

[0004] The main purpose of the utility model is to provide a single-sided side milling cutter, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Preferably, the limiting mechanism includes a screw, the left end of the screw is fixedly connected to a handle, the right end of the screw is movably connected to a movable sleeve, the right end of the movable sleeve is fixedly connected to a moving block, the front and rear ends of the moving block are fixedly connected to sliding blocks, and the right end of the moving block is fixedly connected to a limiting block.

[0008] Preferably, the screw rod is interlaced with the fixed block, and the movable block is located inside the fixed block.

[0009] Preferably, the two sliding blocks are both slidably connected to the inner wall of the fixed block, and the handle is located outside the fixed block.

[0010] Preferably, one end of the limiting block away from the moving block extends into the slot, and one end of the limiting block away from the moving block is engaged and connected with the corresponding limiting slot.

[0011] Preferably, the plug post is inserted and connected with the slot, and the lower end of the blade is in contact with the blade rod.

[0012] Preferably, the two positioning strips are respectively engaged and connected with the two positioning grooves.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. Insert the plug under the blade into the slot above the tool bar, and then turn the two knobs. The two knobs drive the two screws to rotate respectively. The two screws drive the two moving blocks to move relative to each other through the two movable sleeves. The two moving blocks drive the two limit blocks to move relative to each other, so that the two limit blocks are respectively connected to the two limit grooves, so that the blade can be easily installed on the tool bar. When the blade is severely worn, the blade can be quickly replaced. According to different processing requirements, the appropriate blade or tool bar combination can be quickly replaced. It is not necessary to replace the entire blade, but only the damaged part, which saves the tool cost. At the same time, by replacing the appropriate parts, it can more accurately meet the requirements of different processing accuracy.

[0015] 2. When the plug post below the blade is inserted into the slot above the blade rod, the two positioning strips are respectively snapped into the two positioning grooves, so that the two limit grooves on the plug post can quickly correspond to the vertical positions of the two limit blocks, which can improve the installation and connection efficiency between the blade and the blade rod.
