Technical Field

[0001] The utility model relates to the technical field of numerical control machining of glass fiber and carbon fiber, and particularly relates to a cutting tool for composite materials. Background Art

[0002] A vertical key milling cutter is a precision tool specifically used for machining grooves, stepped surfaces, etc., and its cutting teeth are ingeniously distributed on the circumference and end faces. During the working process, it usually cannot perform axial feeding, but if it is equipped with end teeth passing through the center, this function can be achieved.

[0003] During the process of making keys, the vertical key milling cutter plays a crucial role and can accurately engrave the required grooves on the keys. However, before actual application, the milling cutter must be stably installed on the key machine. Currently, the common installation method is to fix the milling cutter through a threaded post on one side of the main shaft of the key machine. Although this method is stable and reliable, it is not very effective in achieving quick installation of the milling cutter.

[0004] In addition, after cutting glass fiber or carbon fiber, the current type of milling cutter often has problems such as fiber fuzzing, wire drawing, delamination at the edges of parts, and uneven surfaces. These technical problems need to be solved urgently to improve the processing quality and efficiency. In view of this, in-depth research on the above problems has led to the generation of this case.

Two pairs of the convex horizontal insertion blocks are respectively inserted movably inside two pairs of the convex telescopic grooves. Two pairs of the horizontal magnet blocks are respectively installed on two pairs of the convex horizontal insertion blocks. A number of the limiting shafts are respectively inserted inside two pairs of the convex telescopic grooves. A number of the limiting sleeve springs are respectively sleeved on a number of the limiting shafts.

[0008] Preferably, the cutting edge diameter of the cutter is 10 mm.

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

For the specific connection and control sequence, the electrical connection should be completed according to the sequence of the working order among the electrical components in the following working principle.

[0019] Embodiment

[0020] As Figure 1-2 shown, the tool 2 is installed on the conduction metal shaft tube 1 through the tool 2 adjustment structure;

[0021] Specifically, the tool 2 adjustment structure includes: a rotating ring block 3, a lifting sleeve ring 4, a rotating ring magnet 5, a plurality of repulsive arc blocks 6, a plurality of repulsive rotating shafts 7, a plurality of repulsive arc magnets 8, a plurality of lifting linear bearings 9, a toothed lifting inner ring 10, two pairs of convex horizontal insertion blocks 11, two pairs of horizontal magnet blocks 12, a plurality of limiting shafts 13 and a plurality of limiting sleeve springs 14;

[0022] Specifically, the rotating ring block 3 is sleeved on the conduction metal shaft tube 1 through a bearing, the cutting tool 2 is inserted inside the conduction metal shaft tube 1, several arc-shaped rotating grooves and two pairs of convex telescopic grooves are formed on the conduction metal shaft tube 1, several repelling arc blocks 6 are respectively inserted inside the several arc-shaped rotating grooves through the repelling rotating shafts 7, several repelling arc magnets 8 are respectively installed on the several repelling arc blocks 6, the rotating ring magnet 5 is installed on the rotating ring block 3, several lifting linear bearings 9 are evenly installed on the conduction metal shaft tube 1, the lifting sleeve ring 4 is sleeved on the several lifting linear bearings 9, the toothed lifting inner ring 10 is installed inside the lifting sleeve ring 4, a toothed lifting groove is formed on the outer side of the rotating ring block 3, two pairs of convex horizontal insertion blocks 11 are respectively inserted inside the two pairs of convex telescopic grooves in a movable manner, two pairs of horizontal magnet blocks 12 are respectively installed on the two pairs of convex horizontal insertion blocks 11, several limiting shafts 13 are respectively inserted inside the two pairs of convex telescopic grooves, and several limiting sleeve springs 14 are respectively sleeved on the several limiting shafts 13;

[0023] It should be noted that in the above, by first stably lifting and lowering the toothed lifting inner ring 10 on the lifting and lowering sleeve ring 4 along the toothed lifting groove on the outer side of the rotating ring block 3, the rotating ring block 3 can be rotated horizontally. Then, the tool 2 is inserted into the inner side of the conduction metal shaft tube 1. By driving the rotating ring block 3 to rotate stably horizontally, the rotating ring magnet 5 on the rotating ring block 3 rotates 180 degrees. By adjusting by changing the magnetic poles on the original rotating ring magnet 5, the magnetism is changed, so as to achieve magnetic repulsion of the repulsive arc magnet 8 and the horizontal magnet block 12. By driving the repulsive arc blocks 6 thereon respectively with a plurality of repulsive arc magnets 8, the repulsive arc blocks 6 are horizontally rotated along the repulsive rotating shaft 7, so as to achieve movably inserting a plurality of repulsive arc blocks 6 into the inner side of the tool 2. The tool 2 is reverse-rotated and limited by a plurality of repulsive arc blocks 6. Similarly, by driving the convex horizontal insertion blocks 11 thereon respectively with two pairs of horizontal magnet blocks 12, the two pairs of convex horizontal insertion blocks 11 are movably inserted into the inner side of the tool 2, so as to limit and fix the tool 2 inside the conduction metal shaft tube 1. Through the cooperation of the two pairs of convex horizontal insertion blocks 11 and a plurality of repulsive arc blocks 6, the inertia generated by rotation is converted into the supporting effect of the repulsive arc blocks 6. At the same time, the horizontal cross-shaped expansion and contraction of the two pairs of convex horizontal insertion blocks 11 are buffered by a plurality of limiting shafts 13. At the same time, the relative expansion and contraction of the two pairs of convex horizontal insertion blocks 11 are buffered by a plurality of limiting sleeve springs 14. At the same time, the toothed lifting inner ring 10 on the lifting and lowering sleeve ring 4 is wound around the inner side of the toothed lifting groove on the rotating ring block 3, so as to achieve stable horizontal limitation of the rotating ring block 3. The DIC on the tool 2 strengthens the hardness and lubrication effect of the tool 2. (Diamond-like Carbon) coating is a coating with high hardness, low friction coefficient and good surface smoothness. It is an amorphous carbon film with the structure of diamond and graphite, combining the high hardness of diamond and the lubricity of graphite. The hardness of this coating is very high, mainly due to its special structure, in which carbon atoms are combined in a special arrangement, forming hardness similar to diamond and lubricity similar to graphite.
