[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a lens milling cutter wear detection device. When the pressing head moves with the threaded block until the alarm button is pressed, the alarm device connected to the alarm button sounds an alarm, indicating that the cutter is severely worn and needs to be replaced. It can detect milling cutters of different specifications. The initial position of the pressing head and the initial distance between the pressing head and the alarm button can be controlled by rotating the hand-tightening knob, which can be used to detect the wear degree of milling cutters of different specifications.

[0026] Figures 1-2 The diagram shown is a structural schematic of one embodiment of the lens milling cutter wear detection device of this utility model. Please refer to [link / reference]. Figures 1-2 The lens milling cutter wear detection device of this embodiment includes an adjustment mechanism 100, a detection mechanism 200, a distance measuring mechanism 300, and a lens milling mechanism 400.

[0027] The adjustment mechanism 100 drives the threaded rod 130 via the variable frequency motor 120 to control the threaded block 140 to move along the guide rail 110, thereby moving the lens milling mechanism 400 to achieve milling of the lens to different depths. Specifically, the adjustment mechanism 100 includes a guide rail 110, a variable frequency motor 120 disposed on the side wall of the guide rail 110, a threaded rod 130 disposed on the output end of the variable frequency motor 120, and a threaded block 140 that cooperates with the threaded rod 130.

[0028] When the pressing head 230 of the detection mechanism 200 moves with the threaded block 140 until the alarm button 240 is pressed, the alarm connected to the alarm button 240 sounds an alarm, indicating that the tool is severely worn and the tool head needs to be replaced. This is to meet the detection of milling tools 420 of different specifications. The initial position of the pressing head 230 is controlled by rotating the hand-tightening knob 220, and the initial distance between the pressing head 230 and the alarm button 240 is controlled to meet the detection of the wear degree of milling tools 420 of different specifications. Specifically, the detection mechanism 200 includes a threaded seat 210 disposed on the side wall of the threaded block 140, a hand-tightening knob 220 that cooperates with the threaded seat 210, a pressing head 230 disposed at the front end of the hand-tightening knob 220, and an alarm button 240 disposed on the side wall of the guide rail 110. In this embodiment, the top of the hand-tightening knob 220 is provided with a rotating end 221, and the side wall of the rotating end 221 is provided with anti-slip texture.

[0029] The ranging mechanism 300 cooperates with the light-transmitting holes on the transparent optical disc 310 through the photoelectric switch 320. The photoelectric switch 320 detects one light signal, which means that the threaded rod 130 rotates 1 / 12 turn, that is, the threaded block 140 moves 1 / 12 of the length of the threaded rod 130 pitch. With the help of an external controller, the distance between the tool and the lens can be flexibly controlled to realize milling operations of different degrees. Specifically, the ranging mechanism 300 includes a transparent optical disc 310 set at the top of the threaded rod 130 and a photoelectric switch 320 cooperating with the transparent optical disc 310. In this embodiment, the transparent optical disc 310 has 12 light-transmitting holes distributed around the side wall of the side wall. The light-emitting end and the receiving end of the photoelectric switch 320 are respectively set on both sides of the transparent optical disc 310.

[0030] The lens milling mechanism 400 controls the rotation of the milling cutter 420 via the milling motor 410 to process the lens. Specifically, the lens milling mechanism 400 moves with the threaded block 140. In this embodiment, the lens milling mechanism 400 includes a milling motor 410 disposed on the side wall of the threaded block 140 and a milling cutter 420 disposed at the output end of the milling motor 410. A bracket 411 is provided on the side wall of the milling motor 410, and the bracket 411 is fixedly connected to the side wall of the threaded block 140.

[0031] Combination Figures 1-2The lens milling cutter wear detection device of this embodiment is used as follows: A variable frequency motor 120 drives a threaded rod 130 to control a threaded block 140 to move along a guide rail 110, thereby moving the lens milling mechanism 400. A photoelectric switch 320, in conjunction with a light-transmitting hole on a transparent disc 310, detects a light signal once, indicating that the threaded rod 130 has rotated 1 / 12 of a turn, meaning the threaded block 140 has moved 1 / 12 of the thread pitch of the threaded rod 130. With the help of an external controller, it can flexibly... The distance between the control tool and the lens is controlled to achieve milling operations of different degrees. When the pressing head 230 moves with the threaded block 140 until the alarm button 240 is pressed, the alarm device connected to the alarm button 240 sounds an alarm, indicating that the tool is severely worn and the tool head needs to be replaced. This meets the requirements for detecting the wear of milling tools 420 of different specifications. The initial position of the pressing head 230 is controlled by rotating the hand-tightening knob 220, which controls the initial distance between the pressing head 230 and the alarm button 240, thus meeting the requirements for detecting the wear degree of milling tools 420 of different specifications.
