In the prior art, a processing method for removing flanging burrs at a through deep long hole adopts a processing method of adding grinding paste into a grinding rod and then carrying out ultrasonic cleaning.
In the prior art, a processing method of adding grinding paste into a grinding rod and then carrying out ultrasonic cleaning is adopted, and the processing method is generally used in the processing of the intersecting deep long hole. The grinding rod is adopted in the machining process, burrs can be effectively removed from each through hole, but due to the fact that through edges exist at the through deep long holes, the straight grinding rod can generate burr flanging in the working process, the straight grinding rod can be turned back and forth in different directions in the working process, and the phenomenon that the removal of the through edges is not complete always exists.
Although the processing method can be used for finally removing the burrs of the deep and long through hole, the phenomenon that the flanging burrs at the through part are not completely removed is often found through endoscopy after ultrasonic cleaning, and the flanging burrs can be completely removed only after some parts are repeated for several times. Aiming at the removal and processing of the flanging burrs of a large number of through deep long holes on a missile body of a certain model, the method mainly has the following defects:
defect 1: the existing processing method adds grinding paste into the grinding rod, and the flanging of the intersecting edge at the intersecting intersection is not easy to remove, so that the flanging burr can not be completely removed.
Defect 2: the existing processing method comprises the steps of adding grinding paste to a grinding rod, then carrying out ultrasonic cleaning, carrying out endoscopy, finding out the phenomenon that burrs are not removed completely in the inspection, repeating the process of removing the burrs by adding the grinding paste to the grinding rod for multiple times, and then carrying out ultrasonic cleaning, wherein the repetition times of some parts are more, and the efficiency is low. However, the number of the deep and long through holes on the body of a certain type of missile is large, so that a new processing method is imperative to improve the processing efficiency.
Defect 3: the existing processing method adds grinding paste into the grinding rod, and due to the fact that the number of product holes is large, after the product is finally delivered, the phenomenon that burrs and flanges still exist in the through deep long hole fed back by a customer is caused, and the problem that unqualified products are delivered is solved.
The above analysis shows that for the processing of removing the flanging burrs of the through deep long holes, the existing processing method of the grinding rod and the grinding paste has the problems of incomplete burr removal, low processing efficiency, delivery of products with problems and the like, and a processing method which fundamentally solves the problem of burr removal of the through deep long holes is urgently needed in production to solve the current situations of incomplete burr removal, low processing efficiency, delivery of products with problems and the like.
Through the analysis, in order to thoroughly remove the flanging burrs of the product through the through deep long holes and achieve high efficiency, the processing efficiency of the existing processing method of the grinding rod and the grinding paste is low, and therefore, the tool and the method for removing the flanging burrs of the through deep long holes are provided on the basis, and the current situation that the processing quality and the processing efficiency are changed can be considered through the tool and the method.
