[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, a tool for processing reducer shaft parts includes: a tool rod 1, and a cutting head 2 arranged at one end of the tool rod 1; the cutting head 2 includes: a maintenance cutting part 21, which is detachably installed on one end of the tool rod 1, and an integrally formed conical cutting part 22 extends from one end of the maintenance cutting part 21, and an integrally formed bottom hole drilling part 23 extends from one end of the conical cutting part 22 away from the maintenance cutting part 21, and a tool head is detachably installed on one end of the maintenance cutting part 21, one end of the conical cutting part 22 and one end of the bottom hole drilling part 23.

[0018] Among them, the maintenance cutting part 21, the conical cutting part 22 and the bottom hole drilling part 23 are provided at one end of the tool rod 1 by means of extension and integral molding, which can effectively improve the structural strength of the cutting head 2 during processing operation, and the tool head is detachably mounted on the maintenance cutting part 21, the conical cutting part 22 and the bottom hole drilling part 23, which can effectively facilitate users to replace it, thereby effectively avoiding the deficiency of the traditional method that the entire tool needs to be replaced due to the overall chipping of the cutting head 2, further reducing the processing cost, and avoiding the scrapping of the entire tool.

[0019] Furthermore, in order to facilitate the classification and installation of the cutter heads that need to be replaced, the cutter heads include: a first blade 3, detachably mounted on one end of the maintenance cutting portion 21; a second blade 4, detachably mounted on one end of the conical cutting portion 22; a third blade 5, detachably mounted on one end of the bottom hole drilling portion 23. By providing different cutter heads on the maintenance cutting portion 21, the conical cutting portion 22 and the bottom hole drilling portion 23, it is possible for users to quickly identify damaged cutter heads and replace them with new ones, thereby improving the efficiency of cutter head replacement and shortening downtime.

[0020] Furthermore, in order to facilitate the installation and replacement of the first blade 3, the second blade 4 or the third blade 5, a threaded groove is provided at one end of the maintenance cutting portion 21, one end of the conical cutting portion 22 and one end of the bottom hole drilling portion 23, and a positioning pin 12 is inserted into the thread inside the threaded groove. The first blade 3, the second blade 4 and the third blade 5 can be fixedly installed by the positioning pin 12, thereby improving the efficiency of installation and replacement; in addition, a locking buckle can be provided at one end of the maintenance cutting portion 21, one end of the conical cutting portion 22 and one end of the bottom hole drilling portion 23, and the first blade 3, the second blade 4 and the third blade 5 are bitten by the locking buckle, thereby achieving the effect of convenient installation and fixation.

[0021] In order to further strengthen the stability of the cutting head 2 installed on the tool rod 1, a positioning pin 12 is provided at one end of the outer periphery of the cutting head 2, and one end of the positioning pin 12 passes through the cutting head 2 and is inserted into the inside of the tool rod 1; thereby improving the stability between the cutting head 2 and the tool rod 1. In order to facilitate the installation of the tool rod 1 on the equipment, the tool rod 1 is designed as a cylindrical structure, and a mounting groove 11 is provided on one side of the outer periphery of the tool rod 1, and one end of the mounting groove 11 extends to one end edge of the tool rod 1. The mounting groove 11 can prevent the tool rod 1 from slipping after being installed on the driving device, and also prevent the tool rod 1 from rolling when placed on a plane.

[0022] Working principle: When in use, the maintenance cutting part 21, the conical cutting part 22 and the bottom hole drilling part 23 provided at one end of the tool rod 1 by means of extension and integral molding can effectively improve the structural strength of the cutting head 2 during processing operation, and the tool head installed in a detachable manner on the maintenance cutting part 21, the conical cutting part 22 and the bottom hole drilling part 23 can effectively facilitate users to implement replacement, thereby effectively avoiding the deficiency of the traditional method that the entire tool needs to be replaced due to the overall chipping of the cutting head 2, further reducing the processing cost, and avoiding the scrapping of the entire tool.
