[0034] As described in the background section, the structure of the key is relatively complex, and the existing clamping tool cannot implement stable clamping of the key. During the laser cleaning process, the key is prone to shaking. Therefore, it is necessary to develop a special key clamping tool to implement stable clamping of the key.

[0035] Therefore, the present application first provides a key clamping tool applied to a key laser cleaning device.

[0037] The first end of the fixing rod 2 is fixedly installed on the chuck 1.

[0038] The clamping assembly 3 is fixedly connected to the second end of the fixing rod 2. The clamping assembly 3 is provided with at least one clamping groove that matches the shape of the key 100 to be cleaned. The clamping groove is used to clamp the key 100 to be cleaned.

[0039] The key clamping fixture 10 provided in this embodiment has a clamping groove on its clamping component 3 that matches the shape of the key 100 to be cleaned, thus enabling stable clamping of the key 100 to be cleaned. Furthermore, the clamping component 3 is fixed to the chuck 1 by a fixing rod 2, preventing accidental rotation of the clamping component 3 and the key 100 on it.

[0040] By using the key clamping fixture 10 in this embodiment to clamp the key 100 to be cleaned, the laser cleaning effect of the key laser cleaning device on the key 100 can be improved.

[0041] The chuck 1 can be any existing chuck structure, such as a pneumatic chuck, capable of clamping the fixed rod 2.

Then, place the key 100 into the lower clamping groove 331. Next, control the upper clamping seat 34 to rotate towards the lower clamping seat 33, so that the upper clamping seat 34 covers the lower clamping seat 33, and the upper clamping groove 341 and the lower clamping groove 331 cooperate to clamp the key 100.

[0050] After the laser cleaning of the clamped key 100 is completed through the exposed port on the upper surface of the upper clamping seat 34, control the upper clamping seat 34 to rotate away from the lower clamping seat 33 again to separate the upper clamping seat 34 and the lower clamping seat 33, and then the key 100 can be taken out from the lower clamping groove 331.

That is, the chuck 1 keeps clamping the sleeve 4 continuously, and during the replacement of the clamping assembly 3, it is not necessary to control the clamping assembly 3 to perform clamping and releasing actions.

[0054] Optionally, a key groove is arranged on the inner wall of the sleeve 4, and a first end of the fixing rod 2 is provided with a flat key matched with the key groove.
