[0002] Keys are essential in daily life, and damage and loss are common. Therefore, key duplication is an essential task. Currently, the most commonly used key-making devices on the market are primarily mechanical key processing machines. These machines are equipped with a detector that detects the outline of the original key, then further process the blank key with a milling cutter to produce a key that matches the original key's contour. However, keying with mechanical key processing machines often requires manual assistance for key positioning and processing, resulting in a relatively low level of automation.

[0003] To solve this problem, electronic key processing technology has emerged on the market. It reads the key's tooth shape information optically and transmits electronic data to the processing organization. The processing organization then uses 3D printing, mechanical processing and other methods based on the electronic data to produce the key. The entire process is highly automated and can effectively improve the efficiency of key production.

[0004] However, in the process of making keys using electronic key processing technology, how to clamp and fix the key during the process of identifying key tooth profile information data is a problem that urgently needs to be solved in the existing technology. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] To achieve the above purpose, the technical solution of the utility model is as follows:

[0033] See also Figure 1-6 As shown, this embodiment provides a key tooth profile data recognition box, including a box body 1 and a clamping and positioning mechanism 2. The clamping and positioning mechanism 2 is connected to the box body 1. The box body 1 has a cavity 3 for accommodating a key.

[0034] Furthermore, the box body 1 is also provided with an identification camera 4 for photographing the key in the cavity 3 and transmitting the photographed photo or video to the control host, which recognizes the key tooth shape data through image processing technology.

[0035] It should be noted that the control host uses photos or videos taken by the camera to identify and compare the key tooth shape data, which is a relatively simple computer image processing technology, which is disclosed in the existing patent with application number CN201711091755.7 and will not be described in detail in this embodiment.

[0036] Furthermore, the clamping and positioning mechanism 2 includes:

[0037] An installation body 21, the installation body 21 is fixed to the box body 1;

[0038] The rotating driving member 22 is fixedly connected to the mounting body 21;

[0039] The swing member 23 is movably connected to the mounting body 21 and is mounted on the output end of the rotating driving member 22;

[0040] The clamping assembly 24 is movably connected to the mounting body 21 and has a clamping groove 25 of adjustable size, the clamping groove 25 being in communication with the cavity 3;

[0041] The mounting body 21 and the box body 1 are both provided with an opening 211, and the clamping groove 25 is arranged opposite to the opening 211;

[0042] The clamping assembly 24 is movably connected to the swinging member 23, so that the swinging member 23 can trigger the clamping assembly 24 to move, thereby adjusting the size of the clamping slot 25 to accommodate keys of different sizes.

[0043] In the present application, when in use, the key is inserted into the clamping groove 25 of the clamping assembly 24 through the opening 211 on the mounting body 21, and the toothed part of the key will extend into the cavity 3 of the mounting body 21 through the opening 211 on the box body 1. After the control mechanism detects that there is a key in the cavity 3, it starts to control the rotation drive member 22 to work, and the rotation drive member 22 drives the swing member 23 to move, and the swing member 23 triggers the clamping assembly 24 to move, so as to adjust the size of the clamping groove 25 to adapt to the size of the key and clamp the key; thereby, the clamping and positioning mechanism 2 can clamp and fix keys of different sizes.

[0044] In this embodiment, the mounting body 21 is essentially a component of the box body 1, that is, a partial structure of the box body 1 is used as the mounting body 21; however, in other embodiments, a separate structure can also be set as the mounting body 21 to achieve modularization of the clamping and positioning mechanism 2 for easy disassembly and assembly.

[0045] Furthermore, the rotation driving member 22 is a motor, and a synchronous wheel 26 is provided between the motor and the swinging member 23. The synchronous wheel 26 is connected to the output end of the motor. The edge of the swinging member 23 is provided with meshing teeth 231, and the swinging member 23 meshes with the synchronous wheel 26 through the meshing teeth 231. The motor drives the swinging member 23 to swing through the synchronous wheel 26, thereby driving the movement of the clamping assembly 24.

[0046] Furthermore, the clamping assembly 24 includes a first slider 241, a second slider 242, and a third slider 243. The first slider 241 and the second slider 242 are arranged horizontally and on the same straight line. The third slider 243 is arranged to cross the first slider 241 and the second slider 242, and the clamping groove 25 is arranged between the first slider 241, the second slider 242, and the third slider 243. The installation body 21 and the box body 1 both include an installation cavity 27, which is communicated with the opening 211. The mounting cavity 27 on the mounting body 21 is located on the inner side wall of the mounting body 21, and includes a first sliding groove 271, a second sliding groove 272, and a third sliding groove 273. The first sliding groove 271, the second sliding groove 272, and the third sliding groove 273 intersect at the opening 211. A supporting protrusion 212 is provided on the side wall of the mounting body 21. The supporting protrusion 212 is located on the side of the opening 211, and the supporting protrusion 212 is arranged opposite to the third sliding groove 273. The first slider 241 is slidably arranged on the first slider 241. The first and second limiting grooves 232, 233 and 234 are provided on the swing member 23. The first limiting grooves 232 and 233 have the same shape and are symmetrically arranged. The first slider 241 has a first limiting protrusion 244, the second slider 242 has a second limiting protrusion 245, and the third slider 243 has a first limiting protrusion 246. It is provided with a third limiting boss 246, the first limiting boss 244 is movably set in the first limiting groove 232, the second limiting boss 245 is movably set in the second limiting groove 233, and the third limiting boss 246 is movably set in the third limiting groove 234; when the swinging member 23 moves, it can drive the first slider 241, the second slider 242, and the third slider 243 to disperse or gather, and adjust the size of the clamping groove 25 in both horizontal and vertical directions to adapt to keys of different widths and thicknesses.

[0047] In the present application, the key is inserted into the opening 211 and supported by the support protrusion 212. When triggered by the swinging member 23, the first slider 241 and the second slider 242 can move relative to or toward each other in the horizontal direction, and adjust the horizontal size of the clamping groove 25 to facilitate adaptation to keys of different widths; the third slider 243 can move in the vertical direction relative to the support protrusion 212, and adjust the vertical size of the clamping groove 25 to facilitate adaptation to keys of different thicknesses, thereby achieving the clamping of keys of different widths and thicknesses.

[0048] Furthermore, the clamping assembly 24 also includes an elastic member 247, the lower end of the elastic member 247 is abutted against the third slider 243, and the upper end of the elastic member 247 is abutted against the installation body 21, so that the third limiting boss 246 is continuously fitted with the bottom wall of the third limiting groove 234. In the present application, since the first limiting groove 232 and the second limiting groove 233 have the same shape and are symmetrically arranged, when the swinging member 23 moves, it can drive the first slider 241 and the second slider 242 to move closer or farther away synchronously, but since the third slider 243 is used to limit the vertical direction of the key, it cannot be synchronized with the first slider 241 and the second slider 242, and can only move asynchronously with the first slider 241 and the second slider 242; under this premise, to ensure that the third slider 243 always clamps the key, the elastic member 247 can only be used to press the third slider 243 downward, and the third slider 243 is pressed on the key through elasticity; at the same time, since the third limiting boss 246 is continuously in contact with the bottom wall of the third limiting groove 234, it can move along the bottom wall of the third limiting groove 234, and can also ensure that the third slider 243 can slide up and down smoothly, thereby realizing the adjustment of the vertical dimension of the clamping groove 25 to adapt to keys of different thicknesses.

[0049] Furthermore, the first sliding groove 271 , the second sliding groove 272 , and the third sliding groove 273 are all linear grooves.

[0050] Furthermore, the first limiting groove 232 , the second limiting groove 233 , and the third limiting groove 234 are all irregular arc-shaped grooves.

[0051] Furthermore, the mounting cavity 27 on the box body 1 is located on the outer wall of the box body 1, and includes a balance wheel limiting groove 274, the swinging member 23 is arranged in the balance wheel limiting groove 274, a balance wheel limiting protrusion 275 is provided in the middle of the balance wheel limiting groove 274, a limiting hole 235 is provided in the middle of the swinging member 23, and the balance wheel limiting protrusion 275 is passed through the limiting hole 235.
