Description

Technical Field

[0001] The utility model relates to the technical field of T-shaped milling cutters, and specifically relates to a T-shaped milling cutter with integrated left and right helixes. Background Technique

[0002] A T-shaped milling cutter with integrated left and right helixes is a special milling cutter design that combines the functions of left and right helixes. The design features of this milling cutter include a tool shank, a tool rod, and multiple cutting edges. The lower end of the tool shank is connected to the upper end of the tool rod, and multiple cutting edges protrude from the side of the tool rod. These cutting edges include several first cutting edges arranged in a left helix and several second cutting edges arranged in a right helix. The left and right helix design enables this milling cutter to cut the upper and lower parts of the workpiece respectively with the cutting edge surfaces of the first cutting edges and the second cutting edges when removing the burrs of the workpiece, thereby improving the burr removal efficiency. In addition, since a finishing edge band is connected to the tail end of the cutting edge surface, the surface roughness value of the workpiece can be reduced and the finish can be improved.

The second annular plate 32 is slidably connected to the knife neck portion 10, and both right ends of the second annular plate 32 are fixedly installed with the sliding rod 31. The right end of the sliding rod 31 is installed with the shielding plate 33; wherein, the thickness of the shielding plate 33 matches the thickness of the blade portion 20.

[0044] The first fixing component includes: a second through hole 70, a second positioning rod 71, a second driving plate 72, a second spring 73, and a second positioning groove 74;

[0045] Both ends of the first annular plate 30 are provided with the second through hole 70. The second positioning rod 71 is slidably connected in the second through hole 70. The second driving plate 72 is fixedly installed at one end of the second positioning rod 71. The second spring 73 is sleeved on the second positioning rod 71, and both ends of the second spring 73 are fixedly connected to the second driving plate 72 and the first annular plate 30 respectively. A plurality of second positioning grooves 74 are opened at the opposite ends of the two groups of sliding rods 31, and the other end of the second positioning rod 71 is inserted into a group of second positioning grooves 74.

[0046] The shielding plate 33 includes: a first arc-shaped plate 40, an arc-shaped hole 41, and a second arc-shaped plate 42;

[0047] Both left ends of the first arc-shaped plate 40 are fixedly installed with the sliding rod 31. The arc-shaped hole 41 is opened in the first arc-shaped plate 40. The second arc-shaped plate 42 is slidably connected in the arc-shaped hole 41 and fixed by a second fixing component.

[0048] The second fixing component includes: a first through hole 50, a first positioning rod 51, a first driving plate 52, a first spring 53, and a first positioning groove 54;

[0050] During specific use, the specific steps are as follows:

[0051] First, the second driving plate 72 is used to move the second positioning rod 71 outward until the second positioning rod 71 is separated from the second positioning groove 74. At this time, the second spring 73 will deform. Then, the second annular plate 32 is used to drive the sliding rod 31 to drive the shielding plate 33 to move until the blade part 20 is located in the shielding plate 33. At this time, the elastic force of the second spring 73 can be used to insert the second positioning rod 71 into a set of second positioning grooves 74. Thus, the position of the shielding plate 33 can be limited. After that, the first driving plate 52 is used to move the first positioning rod 51 outward until the first positioning rod 51 is separated from the first positioning groove 54. At this time, the first spring 53 will deform. Then, the second arc-shaped plate 42 is slid in the arc-shaped hole 41 until the second arc-shaped plate is in a suitable position. At this time, the elastic force of the first spring 53 can be used to insert the first positioning rod 51 into the first positioning groove 54. Thus, the shielding range can be adjusted. When the blade part 20 operates, the splashes generated by it will be blocked by the shielding plate 33. In addition, the shielding plate 33 will move in the formed groove to prevent the shielding plate 33 from rotating.

[0052] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
