Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, a combined alloy cutter comprises a cutter head 1, chucks 2 are movably mounted on two sides of the cutter head 1, mounting holes 3 penetrating through the cutter head 1 are formed in the chucks 2, limiting blocks 4 are fixed on the outer side walls of the mounting holes 3 on the cutter head 1, limiting grooves 5 matched with the limiting blocks 4 are formed in the inner walls of the mounting holes 3 on the chucks 2, fixing holes 10 penetrating through the cutter head 1 are formed in the chucks 2, a placing groove 6 is formed in one side of the inner wall of each fixing hole 10, a connecting sheet 7 is fixed at one end, far away from the fixing hole 10, in each placing groove 6, a fixing sleeve 8 is fixed on each connecting sheet 7, and a screw 9 in threaded connection with the chuck 2 on the other side is rotatably connected in the fixing sleeve 8; when the cutter head 1 needs to be replaced, the screw rods 9 are all removed, then the two chucks 2 are separated, so that the cutter head 1 can be replaced, and the removed screw rods 9 and the connecting pieces 7 are fixed in the placing grooves 6.

As shown in fig. 3, the upper end face of the connecting piece 7 is flush with the upper end face of the screw 9, and after the screw 9 is installed, the upper ends of the connecting piece 7 and the screw 9 are flush with the upper end face of the chuck 2, so that the outer ends of the connecting piece 7 and the screw 9 can be further protected from being hit by external force.

As shown in fig. 3, the screw 9 is disposed in an embedded hexagon, which is used to reduce the probability of the rotational slip angle of the screw 9 during installation, improve the efficiency of rotational installation, and further prevent the installation of the screw 9 from rotating the slip angle.

As shown in fig. 2, the upper end of the screw 9 is flush with the upper end surface of the chuck 2, and when the cutter head 1 and the chuck 2 rotate, the screw 9 is flush with the chuck 2 to protect the outermost mounting edge of the screw 9, so that the screw 9 is not subjected to external impact force, the screw 9 is further protected, and the stability of the chuck 2 is further improved.

As shown in fig. 3, the outer diameter of the fixing sleeve 8 is not smaller than the inner wall diameter of the fixing hole 10, the fixing sleeve 8 is brought into the fixing hole 10 when the screw 9 is installed, and the fixing sleeve 8 is made of elastic material, so that the fixing hole 10 can be plugged, the screw 9 can be fixed more stably, and a gap between the screw 9 and the fixing hole 10 is plugged, so that dust is prevented from blocking the gap.

The working principle is as follows: during the use, when the blade disc 1 needs to be changed, take off screw rod 9 is whole, then separate two (holding) chucks 2, can change blade disc 1 like this, screw rod 9 and connection piece 7 taking off are fixed in standing groove 6, the speed of changing blade disc 1 can not be influenced because of looking for screw rod 9 at the in-process of short change blade disc 1 like this, and can make the fixed orifices 10 on two (holding) chucks 2 and the fixed orifices 10 on the blade disc 1 correspond to each other through stopper 4 and spacing groove 5, make things convenient for the fixed mounting of (holding) chuck 2 and blade disc 1 like this.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
