[0034] Reference Figure 1-2 An embodiment of the present invention provides a tooth shape learning device for a key processing machine, which is applied to a key processing machine for copying keys, and includes a cutter disc 100, a cutter disc probe 200, a second transmission assembly and a first transmission assembly. The key processing machine includes a key clamp for clamping a key.

[0035] Among them, the cutter disc 100 is used to process the embryonic key of the key teeth to be processed, and is in the shape of a ratchet. Its ratchet teeth are used to contact the embryonic key and process the embryonic key by rapid rotation; the cutter disc probe 200 is used to obtain the tooth shape data of the original key, including a contact part 210, which is arranged at one end of the cutter disc probe 200, is semi-annular, and has an opening facing outward. The contact part 210 includes a conductive sheet 211, which is arranged on one side of the annular opening, and the two ends of the conductive sheet 211 are respectively connected to the side surfaces of the two arms of the opening.

[0036] Reference Figure 2-Figure 3The first transmission assembly includes a first shaft 410, a first transmission mechanism 420 and a first motor 430. The first motor 430 is preferably a reduction stepping motor. The first motor 430 is connected to the first transmission mechanism 420. The first transmission mechanism 420 is connected to the first shaft 410. The end of the cutter head 200 opposite to the contact portion 210 is recorded as a connection end 220. The connection end 220 is connected to the first shaft 410. The first motor 430 is energized to drive the first transmission mechanism 420. The first transmission mechanism 420 drives the first shaft 410 to perform intermittent reciprocating rotational motion, so that the contact portion 210 of the cutter head 200 performs tangential reciprocating motion with the connection between the cutter head 200 and the first shaft 410 as the center point, so that the contact portion 210 can be in contact with The cutter head 200 moves back and forth between the position matching the original key and the position away from the original key. When the cutter head probe 200 is rotated to the position matching the original key through the first transmission assembly, the conductive sheet 211 of the contact portion 210 contacts the original key to form a conductive circuit to record the tooth shape data of the original key. Specifically, each time the tooth shape data of the original key needs to be obtained and the tooth shape learning is performed, the cutter head probe 200 is driven by the first motor 430 to rotate so that the contact portion 210 is located at a position matching the original key. When the tooth shape data of the original key is obtained and the tooth shape learning is completed, the cutter head probe 200 is driven by the first motor 430 again, and the contact portion 210 rotates to a position away from the original key, so that the cutter head 100 can subsequently process the embryo key.

[0037] The second transmission assembly includes a second shaft 310, a second transmission mechanism 320 and a second motor 330. The second motor 330 is preferably a brushless DC motor. The second motor 330 is connected to the second transmission mechanism 320, and the second transmission mechanism 320 is connected to the second shaft 310. When the tooth shape data of the original key is obtained, the cutter head 200 is away from the position of the original key. At this time, after processing the tooth shape data, the embryo key is processed, and the second motor 330 is started to drive the second transmission mechanism 320 to drive the second shaft 310 to rotate, wherein the cutter head 100 is fixedly sleeved on the second shaft 310, the second shaft 310 rotates, and the cutter head 100 also rotates. When the ratchet of the cutter head 100 contacts the embryo key, the embryo key will be processed to obtain a duplicate key consistent with the original key.

[0038] Specifically, the second transmission mechanism 320 is a belt transmission mechanism, which is arranged at the top of the second shaft 310 and the second motor 330, and the two are driven by a belt. In this embodiment, one end of the second shaft 310 is connected to the cutter disc 100, and the other end is connected to the belt transmission mechanism, that is, the belt transmission mechanism is located at the end away from the cutter disc 100.

[0039] Compared with traditional tooth shape learning devices, the tooth shape learning device provided above does not require an additional reference calibration structure or additional manual operation, and is more convenient and efficient to use. Moreover, it is no longer a vertical milling or horizontal milling cutter processing method, but can achieve tooth shape learning and key processing on the side, which is more flexible to use and has higher overall learning accuracy.

When the first shaft 410 drives the sleeve 440 to rotate, the sleeve 440 drives the cutter head 200 to rotate through the face gear 450. In this embodiment, the sleeve 440 is sleeved on the first shaft 410, and one end extends to the outside of the first shaft 410 to connect with the toothed end face.

The rotating cam 421 is fixedly sleeved on one end of the axis of the first motor 430, and the protrusion 421-1 contacts the inner wall of the sleeve portion 422-1. When the first motor 430 is working, its axis drives the rotating cam 421.
