Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a shock-resistant milling cutter. Background Art

[0002] A milling cutter is a rotating tool used for milling. A milling cutter is generally composed of one or more teeth, and during the milling process, these teeth will intermittently cut off the excess material of the workpiece in turn. The main function of the milling cutter is to remove excess material on the workpiece during the milling process, so as to obtain the required shape and surface quality.

[0003] The existing milling cutters have some defects in the process of processing workpieces. The main reason is that the milling cutter is subjected to a large lateral force during high-speed cutting, so that the vibration amplitude of the tool is large, causing resonance between the milling cutter and the workpiece, thereby reducing the service life of the milling cutter and seriously affecting the accuracy of the processed workpiece. Therefore, technical personnel in this field provide a vibration-resistant milling cutter to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a vibration-resistant milling cutter, in which a vibration-resistant rod is slidably arranged inside the blade body of the milling cutter, and the resonance phenomenon is effectively avoided under the action of the vibration-resistant rod and the damping ring, thereby extending the service life of the milling cutter.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-vibration milling cutter, comprising a blade module, a blade module having a threaded surface on one side thereof, the blade module comprising a blade body, a first circular hole being provided on a surface on one side thereof, an anti-vibration rod being slidably provided on a surface on one side thereof through the first circular hole, and a plurality of damping rings being fixedly connected to the surface of the anti-vibration rod;

[0006] The knife bar module includes a knife bar body, a second circular hole is opened on one side surface of the inner side of the knife bar body, a magnetic ring is fixedly connected to one side surface of the second circular hole, a magnetic handle is magnetically arranged on one side surface of the magnetic ring, a connecting rod is fixedly connected to the center of one side surface of the magnetic handle, and a cleaning brush is fixedly connected to one side surface of the connecting rod.

[0007] Through the above technical scheme, because a shock-absorbing rod is slidably arranged inside the blade body, and a plurality of damping rings are fixedly connected to the surface of the shock-absorbing rod, the milling cutter can cooperate with the shock-absorbing rod and the damping ring when working, so that when the milling cutter performs high-speed rotation cutting, the resonance phenomenon can be effectively prevented, thereby avoiding vibration marks on the surface of the workpiece, and at the same time, the vibration amplitude of the milling cutter can be reduced, thereby extending the service life of the milling cutter. After the milling cutter completes the work, a large amount of debris will remain inside the milling cutter head. At this time, the staff can use a cleaning brush to clean the debris on the surface of the milling cutter, and for places that are difficult to clean, the magnetic handle can be used to magnetically absorb the debris. By combining these two methods, the cleaning degree of the milling cutter head can be improved.

[0008] Furthermore, a milling cutter head is fixedly connected to one side surface of the blade body, and an anti-slip ring is movably provided on the other side surface of the blade body;

[0009] Through the above technical scheme, the surface of the workpiece can be cut under the action of the milling cutter head, and the connection strength between the blade body and the shank body can be improved under the action of the anti-slip ring.

[0010] Furthermore, a threaded rod is fixedly connected to the center of one side surface of the tool rod body, and an inner ring groove is provided on one side surface of the tool rod body;

[0011] Through the above technical solution, the blade body and the shank body can be threadedly connected under the action of the threaded rod, and the main function of the inner ring groove is to place the anti-slip ring.

[0012] Furthermore, slots are provided around the surface of the other side of the blade rod body near the center;

[0013] Through the above technical solution, the main function of the slot is to allow the plug-in block of the sealing cover to be inserted therein.

[0014] Furthermore, a sealing cover is magnetically attached to the other side surface of the blade body;

[0015] Through the above technical solution, the cleaning brush inside the second circular hole can be sealed under the action of the sealing cover.

[0016] Furthermore, plug blocks are fixedly connected to the surface of the upper end of the sealing cover away from the center, and a plurality of upper end surfaces of the plug blocks are fixedly connected to magnetic absorption layers;

[0017] Through the above technical solution, the connection strength between the sealing cover and the shank body can be improved through the cooperation between the insert block and the magnetic attraction layer.

[0018] Furthermore, a limiting column is fixedly connected to the center of the upper end surface of the sealing cover;

[0019] Through the above technical solution, the cleaning brush inside the second circular hole can be limited by the action of the limiting column.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model proposes a vibration-resistant milling cutter. Before the milling cutter is processed, a vibration-absorbing rod with a damping ring is slid into the first circular hole inside the blade body, and then the blade body and the shank body are threaded together. When the cutter head of the milling cutter cuts chips on the surface of the workpiece, the vibration-resistant component composed of the damping ring and the vibration-resistant rod can effectively prevent the resonance phenomenon when the milling cutter cuts the workpiece at high speed, effectively avoiding the appearance of vibration marks on the surface of the workpiece during cutting. At the same time, the vibration amplitude of the milling cutter is reduced under the action of the vibration-resistant rod and the damping ring, thereby extending the service life of the milling cutter.

[0022] 2. The utility model proposes an anti-vibration milling cutter. After the milling cutter completes processing on the workpiece surface, a large amount of workpiece debris will remain on the surface of the milling cutter. At this time, the sealing cover is opened to take out the cleaning brush, and then the staff uses the cleaning brush to clean the debris on the surface of the milling cutter. When faced with places that are difficult to clean, the difficult-to-handle places can be magnetically attracted by the magnetic handle, so that they are magnetically attracted to the surface of the magnetic handle. Therefore, the magnetic handle and the cleaning brush are combined with each other, thereby improving the surface cleanliness of the milling cutter after processing, and avoiding the residual debris from affecting the subsequent workpiece processing.
