Field of the Invention The present invention relates to a laser assisted rotary cutting apparatus which has the advantages of solving the problem of difficulty in cutting at the center of rotation, processing speed, and high safety. [Prior Art] A conventional rotary cutting apparatus 'shown as shown in the first figure' is a typical drill bed 80 having at least one rotary chuck 81, a drill bit 82, and a cutting fluid ejector 83. The drill bit 82 is fixed to the rotary chuck 81 and is movable up and down, and a workpiece 90 is cut by the 13⁄4 speed rotation of the drill bit 82. In general, the cutting fluid ejector 83 ejects a opaque (e.g., opalescent) coolant 84 to reduce the temperature at which the bit 82 is rotated at high speed to cut the workpiece. The biggest problem with the drill bit 82 when drilling is that regardless of the diameter of the drill bit 82, the tangential speed is closer to the center (e.g., at point a) than the periphery (e.g., point b) when rotated.

The general practice is to increase the speed. However, the speed of the tool also reduces the life of the tool and the problem of requiring more cooling. The conventional laser processing device, as shown in the second figure, adds 17G to the laser after the integration. It has a laser light generating portion η that is used to perform laser cutting or drilling of the workpiece 9〇. The work of the laser light 72 is the ancient bamboo 俨 菩, 疋 will return to this 罝 beam, so the processing g is smaller. In addition, the laser light 72 makes it easy for the road to accidentally hurt the operation ^ 200904576 The safety is low. However, since the above two conventional devices cannot be combined and processed at the same time, they can only be used interchangeably at most. Even if it is used alternately, it is very troublesome in operation, especially when the laser light 72 is used, there is no blocking of the cooling liquid 84. However, when the drill bit 82 is drilled, there must be a coolant 84, which must be alternated. Removing/replenishing the coolant 84' In addition, re-alignment and correction when used alternately is time consuming and cumbersome. Therefore, it is necessary to develop new products to solve the above disadvantages.

The present invention provides a laser-assisted rotary cutting processing apparatus, comprising: a base having at least a first space and a second space; a t-type rotating clamp disposed in the first space Suspected along a reference axis, the hollow rotating jig has at least one collet and a central passage, and the 疋-turning cutting tool is fixed to the collet, and has all the blade portions and guiding channels. The channel system is coaxial with the reference axis, and the guiding channel has a guiding inlet and a guiding outlet; 200904576 a liquid supply system is disposed in the second space, the liquid supply system has at least one liquid supply portion and a liquid supply passage for supplying a cutting coolant having sufficient light transmittance. The liquid supply passage guides the cutting coolant into the central passage; a laser system has at least a laser light generating portion and a laser light guiding bow channel for generating a laser beam; the laser beam is guided by the laser light guiding channel, the guiding inlet and the guiding channel And by Lead exit opening, and to remove the object to be processed. The above objects and advantages of the present invention will be readily understood from the following detailed description of the preferred embodiments illustrated herein. The present invention will be described in detail below with reference to the accompanying drawings: FIG. 2, FIG. 2, FIG. 2 and FIG. 5 are the first embodiment of the present invention, a laser-assisted rotary cutting processing device The pedestal 1G has a -first space u and a second space 12; a hollow rotary rotator 20 is disposed in the first space u and rotatable along a reference axis 21, The hollow rotating jig (9) has at least a collet and a central passage 23; the cutting tool 3 is (for example, a drill bit, a milling cutter or other cutting jig and is fixed to the collet 22, which has a _ cutter portion 31 and a guiding channel, the guiding channel 32 is associated with the reference axis 21, and the guiding channel is provided with a guiding inlet 321 and a guiding outlet 322; 7 200904576 a liquid supply system 40 is provided In the second space 12, the liquid supply system has at least a liquid supply portion 41 and a liquid supply passage 42 for supplying a cutting coolant 43 having sufficient light transmittance (for example, water). Or a liquid having two light transmissibility, the liquid supply channel 42 cooling the cutting 43 is introduced into the central passage 23; a laser system 50 has a laser light generating portion 51 and a laser light guiding channel 52 for generating a laser beam 511 The beam 511 passes through the laser light guiding channel 52, the guiding inlet 32, and the guiding channel 32, and is emitted by the guiding outlet 322 for removing the object to be irradiated. In the first implementation described above In the example, the laser light generating unit 51 is located at the other end of the chuck 22 of the hollow rotating jig 20 and is coaxial with the reference axis 21. The principle of the present invention is mainly ingeniously blending "cutting" and "internal" The liquid guide is integrated with the “laser machining via internal liquid guide.” [a] Cutting part: cutting (either drilling or sharp) by the cutting edge of the rotary cutting tool & contact - workpiece. [b] Internal liquid guiding: a guiding passage 32 is provided inside the rotary cutting tool 3, and the cutting coolant 43 can be guided to the cutting processing. However, the cutting coolant 43 used must have sufficient Translucent (preferably completely transparent liquid, its light transmission The best performance.) [c] Laser processing by internal liquid guiding: mainly for the rotary cutter 8 200904576 30 in the center of the 30 due to the low tangential speed and difficult to cut into the problem 'to make the laser system 50 issued The laser beam 51 passes through the laser light guiding channel 52, the guiding inlet 321 and the guiding channel 32, and is emitted by the guiding outlet 322, and is used for removing an object that is irradiated to the auxiliary rotating cutting. In the center of the tool, it is difficult to cut into the problem. Therefore, in addition to retaining the original cutting function, the rotary cutting tool 30 has an internal guiding passage 32 for guiding not only the cutting coolant 43 but also the laser beam 511. It is a clever combination of "cutting", "internal liquid guiding" and "laser processing with internal liquid guiding". Next, referring to the sixth, seventh and eighth figures, which are the second embodiment of the present invention, the base 10, the hollow rotating jig 20, the rotary cutting tool 30, the liquid supply system 40 and the same The laser system 50 is basically the same as the first embodiment, and therefore will not be repeated. The difference is that the hollow rotating jig 20 further comprises: a lateral light guiding channel 24; the rotary cutting tool 30 further comprises: a plurality of auxiliary guiding channels 33 (two in the second embodiment, the number can be increased) Each of the auxiliary guiding channels 33 does not contact the guiding channel 32, and each of the auxiliary guiding channels 33 has an auxiliary guiding inlet 331 and an auxiliary guiding outlet 332; Flowing through, the laser beam 511 is also provided to pass (the laser beam 511 is reflected by the auxiliary guiding outlet 332 several times in the curved auxiliary guiding channel 33 to prevent the removal from being irradiated to one of the laser beam 511. object). The laser light generating portion 51 is located on one side of the hollow rotating gear 2 垂直 and perpendicular to the reference axis 21, and the laser system 5 〇 further includes: a mirror 53 for the lightning The laser beam 511 generated by the light generating portion 51 is reflected into the guiding channel 32 of the rotating cutting tool 3 and the auxiliary guiding channel 33; a position sensor 54 is used to sense the position of the hollow rotating jig; A controller 55 is configured to read the position signal of the position sensor 54 to control the laser beam 52 to be emitted when the Leixian production switch 51 is in the most red scale channel 24 . Therefore, the laser beam of the second embodiment has three beams, one in the center and the other two in the side. In addition, the intensity of the laser beam can be adjusted as needed, so that the removal speeds of both "laser" and "cutting" are substantially synchronized. Of course, it can also be modified to be "laser" stronger, and lead one or more laser recesses (as shown in the third and sixth figures), so that it has a guiding effect, so that the whole removal The job is more precise and faster. In summary, the advantages and effects of the present invention can be summarized as follows: [1] Solving the problem of being difficult to cut at the center of rotation. Since the rotation of the present invention is set at the center of rotation of the cutting tool for the removal of the laser light, regardless of the rotation speed, it is possible to solve the problem that the center of rotation of the rotary cutting tool is not easily cut. [2] Fast processing speed. The present invention is carried out simultaneously with both rotary cutting and laser removal, so that the overall removal speed is fast. [3] High security. Since the laser light of the present invention advances in the guiding channel of the rotary cutting tool and in the auxiliary guiding channel, it is directly hit on the workpiece to be processed, thereby reducing the exposure of the laser light and accidentally hurting the operator. Sex 'is therefore' safer. The present invention has been described in detail by the preferred embodiments of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention may indeed achieve the aforesaid purpose.
