Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-2.

Referring to fig. 1, for the utility model discloses a milling cutter assembly, including milling cutter 1 and antiskid cover 2, antiskid cover 2 is installed on milling cutter 1.

The milling cutter 1 comprises a cutter head 11 and a cutter handle 12, one end of the cutter head 11 is connected with one end of the cutter handle 12, and a spiral cutting edge is arranged on the cutter head 11 and used for machining on a workpiece.

The handle 12 includes a transition section 121 and a mounting section 122, one end of the transition section 121 is connected with the tool bit 11, the other end is connected with the mounting section 122, and the mounting section 122 is sleeved with the anti-slip sleeve 2. The cutter head 11 and the mounting section 122 are basically cylindrical as a whole, the central axes of the cutter head 11 and the mounting section 122 are on the same straight line, and the diameter of the cross section of the cutter head 11 is smaller than that of the cross section of the mounting section 122. The outer wall of the transition section 121 is a tapered surface, and the diameter of the cross section of the transition section 121 gradually increases from the direction close to the tool bit 11 to the direction close to the mounting section 122, so that the tool bit 11 and the mounting section 122 can smoothly transit.

Referring to fig. 1, the anti-slip sleeve 2 is made of rubber, the anti-slip sleeve 2 has elasticity and a rough surface, and the anti-slip sleeve 2 is in interference fit with the installation section 122, so that the installation of the anti-slip sleeve 2 on the installation section 122 is realized. Referring to fig. 2, the middle of the mounting section 122 is provided with a protruding portion 1221 for preventing the anti-slip cover 2 from slipping, the protruding portion 1221 and the mounting section 122 are integrally formed, and the anti-slip cover 2 covers the protruding portion 1221 outside the protruding portion 1221.

Referring to fig. 2, install antiskid cover 2 back on installation section 122, bulge 1221 is located between installation section 122 and the antiskid cover 2, bulge 1221 struts antiskid cover 2, thereby increase the deformation degree of antiskid cover 2, and then increase the effort of antiskid cover 2 to installation section 122, make the installation of antiskid cover 2 on installation section 122 more firm, and difficult slipping, compare antiskid cover 2 and only connect in installation section 122, this novel milling cutter 1 stability that can improve of use, thereby improve the work piece quality.

The setting of the conical surface of the transition section 121 enables the anti-slip sleeve 2 to be sleeved into the mounting section 122 from the end, far away from the mounting section 122, of the tool bit 11, the transition section 121 can guide the anti-slip sleeve 2, the anti-slip sleeve 2 can easily slide into the mounting section 122 from the tool bit 11, the installation of the anti-slip sleeve 2 on the mounting section 122 is facilitated, and the anti-slip sleeve 2 is convenient to install.

Further, the cross section of the protruding portion 1221 along the axial direction of the mounting section 122 is an ellipse, and the long axis of the protruding portion 1221 is axially perpendicular to the axial direction of the mounting section 122. The arc of the projection 1221 facilitates the projection 1221 to slide the anti-slip cover 2 onto the projection 1221, thereby further facilitating the installation of the anti-slip cover 2 on the installation portion.

In order to enable the anti-slip sleeve 2 to be stably installed on the installation section 122, the surface of the protruding portion 1221 is provided with anti-slip threads (not shown in the figure) for increasing the friction force between the protruding portion 1221 and the anti-slip sleeve 2. And, the mounting section 122 outer wall is equipped with annular spacing portion 1222 in the bulge 1221 is kept away from transition section 121 one side, and spacing portion 1222 is made by the magnet, and spacing portion 1222 can restrict the anti-skidding cover 2 from the tool bit 11 to pass mounting section 122 towards the direction of being close to mounting section 122. After the anti-slip sleeve 2 is sleeved on the protruding portion 1221, the limiting portion 1222 is arranged on one side of the anti-slip sleeve 2 away from the tool bit 11, and one side of the anti-slip sleeve 2 away from the tool bit 11 can abut against one side of the limiting portion 1222 close to the tool bit 11, so that the anti-slip sleeve 2 is limited to continue to slide.

The side of the anti-slip sleeve 2 far away from the tool bit 11 is provided with an annular blocking piece 21 capable of blocking the limiting portion 1222 from entering the anti-slip sleeve 2, and the blocking piece 21 is made of a magnet and can attract the limiting portion 1222. Keep away from installation section 122 one end with anti-skidding cover 2 from tool bit 11 and embolia installation section 122, anti-skidding cover 2 slides on installation section 122, it slides to drive separation blade 21, when anti-skidding cover 2 slides to being connected with bulge 1221, the one side that tool bit 11 was kept away from to separation blade 21 can be close to the one side butt of tool bit 11 with spacing portion 1222, thereby prevent that milling cutter 1 is not hard up, and restriction anti-skidding cover 2 continues to slide, make install milling cutter 1 back on the milling machine, milling cutter 1 can not stretch out the cutter holder gradually under spacing portion 1222's effect, thereby further improve milling cutter 1's stability.

Referring to fig. 1, further, because the separation blade 21 and the limiting portion 1222 are two magnets which attract each other, when the separation blade 21 slides to be close to the limiting portion 1222, the separation blade 21 can attract each other with the limiting portion 1222, which is not only beneficial to fast positioning and connection of the anti-slip sleeve 2 on the protruding portion 1221 (see fig. 2), but also can prevent the separation of the separation blade 21 and the limiting portion 1222 to a certain extent, so that the connection of the anti-slip sleeve 2 and the handle 12 is more stable, and the purpose of further improving stability is achieved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
