Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to a fixing device for processing a cut surface lens. Background Art

[0002] Faceted lenses generally refer to lenses with specific facets or geometric shapes that can change the path of light or produce specific optical effects. Compared with traditional spherical or aspherical lenses, the design of faceted lenses is more complicated because they need to consider additional geometric parameters and optical properties. The processing process of faceted lenses is similar to that of traditional lenses, but also includes additional cutting and grinding steps to form the required facets. The following are some key steps in the processing of faceted lenses: Design: First, the geometry and optical properties of the lens are designed according to the requirements of the optical system. This usually involves the use of professional optical design software. Material selection: Select lens materials suitable for specific applications. Common lens materials include optical glass, crystal, plastic, etc. Rough machining: Cut the lens material into a blank close to the final shape. This step may include sawing, milling or grinding. Fine grinding: Use finer grinding tools to finely process the lens surface to approach the final optical surface. Polishing: Polish the lens surface to achieve the desired finish and optical quality.

[0003] When processing a faceted lens, the material needs to be fixed. However, we consider that it is not convenient to fix the material as a whole when fixing the lens material in the prior art, so that there are too few stress points, which will affect the stability of the material and the quality of the material, which is extremely inconvenient. Therefore, a fixing device for faceted lens processing is urgently needed to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fixing device for processing faceted lenses comprises a frame, the inner side of the frame is rotatably connected to a bidirectional screw, and one side of the outer wall of the frame is fixedly connected to a driving motor by bolts, both ends of the bidirectional screw are screwed to nut seats by threaded engagement, and one side of the two nut seats is fixedly connected to a fixing plate, and one side of the two fixing plates is fixedly connected to a telescopic rod, and the opposite sides of the two telescopic rods are fixedly connected to a cushion, a bearing plate is provided at the lower inner side of the frame, and one side of the bottom of the frame is fixedly connected to a cylinder by bolts, and the output shaft of the cylinder passes through the bottom of the frame and is fixedly connected to the bottom of the bearing plate.

[0007] Preferably, one end of the bidirectional screw is rotatably connected to the inner wall of the frame through a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the frame through a bearing sleeve.

[0008] Preferably, one side of the two nut seats is fixedly connected with a slider, and the two sliders are slidably connected to the inner wall of the frame through a slide rail.

[0009] Preferably, an air pump is fixedly connected to one side of the inner side of the frame by bolts, and two outlets of the air pump are connected to air pipes, and one end of the two air pipes is respectively connected to one end of the two telescopic rods.

[0011] Preferably, the two sliding blocks are clearance-fitted with the two sliding rails respectively.

[0012] The utility model has at least the following beneficial effects:

[0013] When the utility model is used as a fixing device for processing a faceted lens, the faceted lens material to be processed is first placed on the top of a carrying plate, and according to the size of the material, the cylinder is started to move the carrying plate up and down so as to place the center of the material between two soft pads, and then the driving motor is started to drive the bidirectional screw to rotate, and then the two soft pads can be driven to approach each other through the nut seat, so that the side of the material can be clamped, and then the side and bottom of the material can be stabilized in cooperation with the carrying plate.
