[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution: an automatic alignment numerical control device, comprising a machine tool 1, a gantry 2 fixed on the machine tool 1, a drive device 3 installed on one side of the gantry 2, a mounting joint 4 and a tool head 5 fixed to the bottom of the mounting joint 4 at the working end of the drive device 3, such as Figure 3 and Figure 4 As shown, the mounting joint 4 is provided with an alignment mechanism 6 for detecting the installation position of the tool head 5, and the alignment mechanism 6 includes a mounting seat 61, which is elastically connected to the mounting joint 4 through an elastic member, and a sleeve 62 is fixed to the bottom of the mounting seat 61, and an inner hole groove is provided on the sleeve 62. An infrared emitter 63 capable of emitting infrared light outward through the inner hole groove is provided in the sleeve 62, and an outer hole groove matching the inner hole groove is provided on the tool head 5. A socket for inserting the tool head 5 is provided at the bottom of the mounting joint 4, and an infrared receiver 68 for detecting the alignment of the inner hole groove and the outer hole groove is provided in the socket, and an electromagnetic lock core 67 for automatically locking the tool head 5 when the infrared receiver 68 detects that the inner hole groove and the outer hole groove are aligned and transmits light.

[0025] See also Figure 4 The mounting joint 4 includes a sleeve 41 and a flange 42 fixed to the top of the sleeve 41, which is used to be fixed to the working end of the driving device 3. A telescopic cavity 44 is opened in the sleeve 41 for sliding and telescoping of the mounting joint 4.

[0026] Furthermore, the elastic member includes a spring 65 and a washer 66. The spring 65 and the washer 66 are both loaded into the telescopic cavity 44. The two ends of the spring 65 respectively abut against the mounting seat 61 and the washer 66. The top of the mounting seat 61 is fixed with a guide sleeve 64 that is slidably set in the mounting joint 4. The spring 65 is sleeved outside the guide sleeve 64. In the initial state, the alignment mechanism 6 in the mounting joint 4 is as shown in FIG. Figure 3 and Figure 4 As shown, the housing 62 extends downward under the elastic force of the spring 65.

[0027] Furthermore, the inner hole groove includes a first light-transmitting groove 621 and a second light-transmitting groove 622 perpendicular to the first light-transmitting groove 621. The infrared light emitted by the infrared emitter 63 can be transmitted from the first light-transmitting groove 621 and the first light-transmitting groove 621 respectively, thereby forming two infrared light rays perpendicular to each other.

[0028] See also Figure 5 The tool head 5 includes a drill rod 51 and a handle 52 fixed to the top of the drill rod 51, and the outer hole groove is located at the handle 52. The outer hole groove includes two light holes 521 and a light groove 522 distributed in a cross shape with the two light holes 521. When assembling the tool head 5, the handle 52 can be put on the outside of the sleeve 62, and the light holes 521 on the handle 52 are made to face the infrared light emitted by the first light-transmitting groove 621, so that the tool head 5 can be guided to be inserted into the socket. When the handle 52 is completely put on the outside of the sleeve 62, the sleeve 62 can be pushed by the handle 52 to compress the spring 65. At this time, the second light-transmitting groove 622 of the sleeve 62 is just flush with the height of the light groove 522. At this time, the light emitted by the infrared emitter 63 can pass through the second light-transmitting groove 622 and the light groove 522.

[0029] Furthermore, a sealing ring 43 is fixed in the socket at the bottom of the mounting joint 4, and a corrugation 524 that matches the sealing ring 43 is provided on the outside of the handle 52. After the tool head 5 is installed, the corrugation 524 on the outside of the handle 52 can fit tightly with the sealing ring 43 to seal the gap and prevent dust from entering during processing to affect installation and disassembly.

[0030] Furthermore, a lock hole 523 compatible with the electromagnetic lock core 67 is provided on the handle 52. When the handle 52 is inserted from the socket to the designed depth position, the light passing through the second light-transmitting groove 622 and the light-aligning groove 522 can just be received by the infrared receiver 68. At this time, the tool head 5 reaches the locking position, and the electromagnetic lock core 67 begins to automatically insert into the lock hole 523, thereby realizing automatic alignment and locking of the tool head 5.

[0031] The working principle and use process of the present invention are as follows: In the initial state, the alignment mechanism 6 in the installation joint 4 is as follows: Figure 3 and Figure 4As shown, the sleeve 62 extends downward under the elastic force of the spring 65. Therefore, when assembling the tool head 5, the handle 52 can be sleeved on the outside of the sleeve 62, and the light hole 521 on the handle 52 is aligned with the infrared light emitted by the first light-transmitting groove 621, so that the tool head 5 can be guided to be inserted into the socket. When the handle 52 is completely sleeved on the outside of the sleeve 62, the sleeve 62 can be pushed by the handle 52 to compress the spring 65. At this time, the second light-transmitting groove 622 of the sleeve 62 is just flush with the height of the light-transmitting groove 522. At this time, the light emitted by the infrared emitter 63 can pass through the second light-transmitting groove 622 and the light-transmitting groove 522. When the handle 52 is inserted from the socket to the designed depth position, the light transmitted from the second light-transmitting groove 622 and the light-transmitting groove 522 can just be received by the infrared receiver 68. At this time, the tool head 5 reaches the locked position, and the electromagnetic lock core 67 starts to automatically insert into the lock hole 523, realizing automatic alignment and locking of the tool head 5.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
