Description
Technical Field
The utility model relates to a lathe part technical field specifically is a novel shock attenuation cutter arbor.
Background
The most common tools for metal cutting are machining devices. The core components of the cutter are a cutter head and a cutter rod connected with the cutter head. The tool relies primarily on the high hardness of the tool in the machining of metal materials and the like so that the metal material can be cut when the cutting edge of the tool bit presses against the surface of the metal workpiece. However, during the cutting process of the metal material, the cut metal simultaneously generates a reaction force acting on the cutter head and then is transmitted to the cutter rest through the cutter bar. Therefore, when the feed amount is large or the cutter rod is long, the cutter vibration phenomenon is easy to occur, so that the surface of the cut metal becomes rough, and the precision requirement of the cut metal is influenced in serious cases. Therefore, the requirements on the strength and the anti-vibration performance of the cutter bar during metal cutting are high.
Disclosure of Invention
The utility model aims to solve the shortcoming that exists among the background art, provide a simple structure, be convenient for installation and maintenance, preparation and the lower novel shock attenuation cutter arbor of installation cost.
For realizing the above-mentioned purpose, the utility model provides a following technical scheme, a novel shock attenuation cutter arbor, include the cutter arbor body and fix the blade at the cutter arbor body front end, the inside cutter arbor chamber that is equipped with of cutter arbor body, the cutter arbor chamber runs through the one end of keeping away from the blade to one end at keeping away from the blade forms cutter arbor accent, has inserted the dabber at the cutter arbor intracavity, the through-hole that link up has been seted up to dabber axis direction the through-hole intussuseption is filled with and shakes the material, has the becket at the both ends outer wall cover of dabber, becket, dabber, cutter arbor body are made by the metal material of each difference of vibration frequency respectively, dabber and becket all paste tight cutter arbor intracavity wall, the cutter arbor accent passes through the screw shutoff.
Furthermore, the metal rings at the two ends of the mandrel are provided with a plurality of metal rings, and each metal ring at the same end is made of metal materials with different vibration frequencies.
Furthermore, the number of the metal rings at two ends of the mandrel is three, and the three metal rings are an aluminum ring, a lead ring and a cast iron ring in sequence from one end close to the blade.
Further, the material of the cutter arbor body is 65Mn, and the material of dabber is 45 steel.
Further, the vibration absorption material is vibration absorption sand.
Furthermore, a mandrel through hole close to one end of the cutter bar cavity opening is provided with an internal thread, and the screw end of the screw is in threaded fastening connection with the mandrel.
The utility model provides a novel shock attenuation cutter arbor has following beneficial effect:
1. the utility model fully utilizes the damping characteristic of the mutually contacted different materials when vibrating, and the vibration absorbing material filled in the central hole of the mandrel is added to absorb the vibration generated by the cutting head, so that the cutter bar can prevent the vibration generated by the cutting head from being transmitted to the cutter rest to the maximum extent to influence the roughness and the accuracy of the cutting;
2. the utility model discloses an aluminium ring, lead ring and cast iron ring can be changed into other materials that natural frequency is different, and its range position and quantity are not limited to increase the convenient for drawing materials nature of various shock rings, still can make its installation simpler with the use, aluminium ring, lead ring and cast iron ring etc. can also reuse simultaneously.
