Description

Technical Field

[0001] The utility model relates to the technical field of four-edge spiral milling cutters, in particular to a high-gloss four-edge spiral tungsten steel milling cutter. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the workpiece's excess in sequence and intermittently. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. Among them, the high-gloss four-edge spiral tungsten steel milling cutter is a type of end mill, also known as a four-edge end mill. Its structure is a cylindrical spiral gear. Its main feature is that it has four blades that can cut and mill materials separately.

[0003] At present, when a high-gloss four-edge spiral tungsten steel milling cutter is used, the cutter body needs to be inserted into the three-jaw chuck at the connection of the milling machine transmission part for fixation. The three-jaw chuck is a tool commonly used to fix the milling cutter. It is used by personnel to use a nut with a wrench to stabilize the milling cutter. After the fixation is completed, the milling cutter is used to mill the mechanical parts. However, in the process of the milling cutter contacting the mechanical parts downward for milling, the milling cutter will suddenly be subjected to a large external force, which will cause the three-jaw chuck at the connection between the milling cutter and the milling machine transmission part to loosen easily, thereby affecting the milling quality of the milling cutter on the mechanical parts.

A spring 6 is sleeved on the lower side of the surface of the fixed column 3, and a transmission plate 7 is fixedly connected to the lower side of the rod wall of the hole rod 5. The transmission plate 7 is a circular plate with a hole opened on the top surface. The hole opened on its surface has the same diameter as the hole rod 5, which facilitates the stable and fixed connection between the transmission plate 7 and the hole rod 5. , fixed openings 8 are provided around the inner wall of the fixed cavity 2, and the inner walls of the four fixed openings 8 are slidably connected to fixed blocks 9, and one side of the four fixed blocks 9 is rotatably connected to a transmission rod 10, and limiting grooves 11 are provided on the upper and lower sides of the inner walls of the four fixed openings 8, and the inner walls of multiple limiting grooves 11 are slidably connected to limiting blocks 12. The limiting grooves 11 and the limiting blocks 12 can limit the fixing blocks 9, which can prevent the fixing blocks 9 from escaping from the inside of the fixed openings 8. During the milling process of the mechanical parts, the device will not loosen due to a sudden large external force between the three-jaw chuck at the connection between the device and the milling machine transmission part, so that the three-jaw chuck at the connection between the device and the milling machine transmission part can be stably connected, thereby improving the milling quality of the mechanical parts by the device.

The spiral shape can facilitate the milling of mechanical parts, so that the debris of the mechanical parts milled by the device can be quickly discharged. The surface of the milling cutter body 1 is located above the four spiral blades 15 and is fixedly connected with a baffle plate 14. The baffle plate 14 is a perforated plate with an arc-shaped bottom surface, which can prevent the debris under the milling of the mechanical parts of the device from entering the inside of the three-jaw chuck at the connection of the milling machine transmission part along the blade of the device, thereby preventing the device from getting stuck. The milling cutter body 1 is made of tungsten steel, which can make the device have the advantages of high hardness, good heat resistance, high wear resistance, good corrosion resistance and good cutting performance.

[0033] Working principle of the present utility model: When the present device is in use, the operator manually fixes the upper end of the present device with the three-jaw chuck at the connection of the milling machine transmission part.
