Description

Technical Field

[0001] The present application relates to the field of window sheet cutting, and in particular, to a device for cutting optical window sheets. Background Art

[0002] A window is a parallel plane plate, usually used as a protective window for electronic sensors or detectors of the external environment. The window does not change the magnification of the system. The substrate materials include various optical glasses, K9, UV fused quartz, infrared fused quartz, and crystal materials such as calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), and silicon (Si). Optical windows are widely used in today's society, and windows need to be cut during processing.

[0003] Announcement No. CN 212919555 U discloses a cutting device for processing window sheets. The base, bracket, top plate, hydraulic cylinder, cutting motor and cutting knife of the device cooperate to facilitate cutting of the window; the fixing mechanism facilitates fixing of the window to avoid displacement of the window sheet during cutting, thereby ensuring the quality after cutting; the positioning plate and the scale cooperate to facilitate cutting of the window sheet at equal distances; the cutting hole, the collecting cover, the collecting box, the suction fan, the suction pipe and the filter screen cooperate to facilitate the treatment of waste chips generated during cutting, thereby ensuring the working environment and protecting people's health.

[0004] However, there are some problems in the above scheme: in the above scheme, a fixing mechanism is set to fix the window piece to be cut, but the degree of compression is based on human perception, and excessive fixing pressure can easily cause the window piece to break, while too little pressure can cause the fixation to be unstable. Moreover, although the positioning plate and the scale can be used for equidistant cutting, it is difficult to quickly adjust the position of the fixed positioning plate, which is not suitable for cutting of different sizes, thus reducing practicality.

[0033] See also Figure 1 , 2 and 3, the fixing assembly 100 includes a workbench 110, a support frame 120, a fixing plate 130, a threaded rod 140, a pressure plate 150 and a digital pressure sensor 160, the support frame 120 is arranged on the top of the workbench 110, the fixing plate 130 is fixedly connected to the support frame 120, the threaded rod 140 threads through the fixing plate 130, the pressure plate 150 is movably connected to the bottom end of the threaded rod 140, and the digital pressure sensor 160 is embedded in the bottom of the pressure plate 150.

[0034] A guide rod 151 is provided on the top of the pressure plate 150, and the guide rod 151 slides through the fixed plate 130. The guide rod 151 is provided to guide the pressure plate 150 to move along the axial direction of the guide rod 151, thereby limiting the rotation of the pressure plate 150 during the thread transmission process.

[0035] In a specific implementation, the threaded rod 140 is fixedly connected to one end away from the pressure plate 150 with a handwheel 141, and the handwheel 141 is provided with an anti-slip pad. By setting the handwheel 141, it is convenient to rotate the threaded rod 140 by turning the handwheel 141, thereby facilitating operation.

[0036] See also Figure 1 , 2, 4 and 5, the limiting assembly 200 includes a positioning plate 210, an adjusting member 220, a scale 240 and a cutting member 250, the positioning plate 210 is slidably arranged on the top of the workbench 110, the adjusting member 220 is arranged between the support frame 120 and the positioning plate 210, the scale 240 is embedded in the top of the workbench 110, and the cutting member 250 is arranged on the top of the support frame 120.

[0037] In a specific embodiment, a slide groove 111 is provided on the top of the workbench 110, and a slider 212 is provided at the bottom of the positioning plate 210. The slider 212 is slidably set in the slide groove 111, and the slider 212 and the inner wall of the slide groove 111 are clearance-matched. By setting the slider 212 and the inner wall of the slide groove 111 clearance-matched, the slider 212 slides along the slide groove 111, thereby realizing the sliding setting of the positioning plate 210 on the workbench 110.

[0038] Specifically, the slider 212 and the slide groove 111 are both trapezoidal, and the top surface of the positioning plate 210 is higher than the top surface of the workbench 110.
