[0018] The technical solution of the present application is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3As shown in the figure, it is an automatic detection mechanism for the wear of an online grooving saw blade, including a frame 1 fixedly arranged on both sides of the saw blade. A detection component 2 is connected to each frame 1, and the detection point of the detection component 2 irradiates on the cutting tooth pitch line point of the saw blade. A sprocket shaft 3 is inserted between the two groups of saw blades, and the sprocket shaft 3 is connected to a driving device through a sprocket transmission mechanism. The output end of the driving device is connected with a rotary encoder 4. The detection component 2 includes a flange base 201 fixedly connected to the frame 1. A sleeve 202 is inserted into the flange base 201. A fixing base 203 is connected inside the free end of the sleeve 202. A laser displacement sensor 204 is connected to the fixing base 203 located inside the sleeve 202. A notch 205 is opened on the outer peripheral surface of the sleeve 202 at the irradiation head of the laser displacement sensor 204. The fixing base 203 includes an arc section 2031, the upper surface of the arc section 2031 is arranged to fit the inner surface of the sleeve 202, and a cover plate section 2032 is integrally arranged at the end face of the arc section 2031. The cover plate section 2032 abuts against the end face of the sleeve 202. A horizontal air cylinder 206 is arranged on the cover plate section 2032. The free end of the piston rod of the air cylinder 206 is connected with a dust-proof cylinder cover 207. The dust-proof cylinder cover 207 is horizontally slid and arranged to fit the outer peripheral surface of the sleeve 202. A window 2071 corresponding to the notch 205 is opened on the outer peripheral surface of the dust-proof cylinder cover 207. The driving device is a speed reducer, and a sprocket is connected to the free end of the speed reducer.

[0020] During operation, the operator controls the air cylinder 206 to work, driving the dust-proof cylinder cover 207 to move, so that the window 2071 on the dust-proof cylinder cover 207 moves to the notch 205 of the sleeve 202, making the irradiation head of the laser displacement sensor 204 exposed, and making the detection point of the irradiation head irradiate on the pitch line point of the corresponding saw blade cutting tooth. During the detection process, the saw blade rotates at a certain speed. The laser displacement sensor 204 controls the detection pulse number between two teeth on the saw blade. The pulse number is compared with the pulse number N0 of the running wear range. When N1 < N0, the saw blade wears normally; when N1 > N0, the saw blade wears, and an alarm prompts to replace the saw blade; when the saw blade rotates one week, the detection of the wear condition of all teeth is completed.

[0021] The present utility model is not limited to the above embodiments. Based on the technical solutions disclosed in the present utility model, those skilled in the art can make some replacements and deformations to some technical features without creative labor according to the disclosed technical content, and these replacements and deformations are all within the protection scope of the present utility model.
