DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides a technical solution: a fixing device for lightweight milling of optical lens blanks, comprising a fixing base 1 and a clamping mechanism 2, wherein the clamping mechanism 2 is arranged on one side of the surface of the fixing base 1, and a locking mechanism 3 is arranged at one end of the clamping mechanism 2;
[0021] The clamping mechanism 2 includes a clamping base 201, a movable groove 202, a servo motor 203, a bidirectional screw 204, a limiting rod 205, a slider 206, a support frame 207 and a clamping block 208. The clamping base 201 is arranged on one side of the surface of the fixed base 1, and the movable groove 202 is opened on one side of the surface of the clamping base 201. The servo motor 203 is installed on one end of the clamping base 201. The bidirectional screw 204 is arranged inside the movable groove 202. The limiting rod 205 is arranged inside the movable groove 202. The sliders 206 are passed through both ends of the bidirectional screw 204. One end of the slider 206 is fixedly connected to the support frame 207, and the other end of the support frame 207 is fixedly connected to the clamping block 208. , the setting of the limit rod 205, the slider 206, the support frame 207 and the clamping block 208. When in use, turn on the servo motor 203, and the servo motor 203 drives the bidirectional screw 204 to rotate inside the movable groove 202. Since the two groups of sliders 206 are respectively threaded on the two end surfaces of the bidirectional screw 204, and the sliders 206 are embedded in the movable groove 202, the limit rod 205 penetrates the two groups of sliders 206, so that when the bidirectional screw 204 rotates inside the movable groove 202, the sliders 206 move closer to each other along the bidirectional screw 204 inside the movable groove 202. At this time, the sliders 206 drive the clamping blocks 208 to move closer to each other through the support frame 207, so that the two groups of clamping blocks 208 moving closer to each other clamp and fix the optical lens blank.
[0022] Furthermore, one end of the bidirectional screw rod 204 passes through the clamping base 201 and is connected to the servo motor 203, and both ends of the limit rod 205 are fixedly connected to the clamping base 201 inside the movable groove 202. Through the setting of the bidirectional screw rod 204, when in use, when the bidirectional screw rod 204 rotates inside the movable groove 202, it can drive the slider 206 to move closer to each other along the bidirectional screw rod 204 inside the movable groove 202.
[0023] Furthermore, two groups of sliders 206 are provided, and the sliders 206 are threadedly sleeved on the surface of the bidirectional screw rod 204, and the sliders 206 are embedded in the inside of the movable groove 202. Through the setting of the sliders 206, when in use, when the sliders 206 move toward each other, the sliders 206 can drive the two groups of clamping blocks 208 to move toward each other through the support frame 207.
[0024] Furthermore, both ends of the limiting rod 205 pass through the slider 206, and the clamping block 208 is an arc-shaped block. Through the setting of the limiting rod 205, when in use, the limiting rod 205 can limit the slider 206 to prevent the slider 206 from directional deviation when moving.
[0025] Furthermore, the locking mechanism 3 includes a threaded hole 301, a spring 302, a screw rod 303, a rotating knob 304, a limiting plate 305, a locking block 306, a limiting hole 307, a limiting groove 308 and a protective plate 309. A threaded hole 301 is provided on one side of the surface of the clamping block 208, and a spring 302 is fixedly connected to one side of the surface of the clamping block 208. A screw rod 303 runs through the inside of the threaded hole 301, one end of the screw rod 303 is fixedly connected to the rotating knob 304, and the other end of the screw rod 303 is fixedly connected to the limiting plate 305. A locking block 306 is sleeved on the surface of the limiting plate 305, a limiting hole 307 is provided on one side of the surface of the locking block 306, a limiting groove 308 is provided inside the locking block 306, and a protective plate 309 is bonded to one side of the surface of the locking block 306. The screw 303, rotating knob 304, limiting plate 305, locking block 306, limiting hole 307, limiting groove 308 and protective plate 309 are arranged. When the clamping block 208 is unstable in clamping the optical lens blank, the rotating knob 304 can be turned. At this time, the rotating knob 304 drives the screw 303 to rotate. Since the screw 303 passes through the clamping block 208 through the threaded hole 301, the screw 303 drives the limiting plate 305 fixed at one end to move. Since the limiting plate 305 is embedded in the locking block 306 through the limiting groove 308, and one end of the spring 302 is connected to the clamping block 208 and the other end is fixedly connected to the locking block 306, the screw 303 drives the locking block 306 to move through the limiting plate 305, and when the locking block 306 is tightly fitted with the optical lens blank, it can be clamped and fixed.
[0026] Furthermore, the screw 303 is threaded through the clamping block 208 through the threaded hole 301, and one end of the screw 303 is embedded in the interior of the locking block 306 through the limiting hole 307. Through the setting of the screw 303, when in use, the screw 303 can drive the locking block 306 to move through the limiting plate 305 when being rotated.
[0027] Furthermore, one end of the spring 302 is fixedly connected to the locking block 306, the limiting plate 305 is embedded in the limiting groove 308, and the protective plate 309 is made of rubber. Through the setting of the protective plate 309, when the locking block 306 is tightly fitted with the optical lens blank during use, the rubber protective plate 309 can prevent the locking block 306 from damaging the optical lens blank.
[0028] Working principle: Turn on the servo motor 203, and the servo motor 203 drives the bidirectional screw rod 204 to rotate inside the movable groove 202. Since the two sets of sliders 206 are respectively threadedly sleeved on the two end surfaces of the bidirectional screw rod 204, and the sliders 206 are embedded in the movable groove 202, the limit rod 205 penetrates the two sets of sliders 206, so that when the bidirectional screw rod 204 rotates inside the movable groove 202, the sliders 206 move closer to each other along the bidirectional screw rod 204 inside the movable groove 202. At this time, the sliders 206 drive the clamping blocks 208 to move closer to each other through the support frame 207, so that the two sets of clamping blocks 208 moving closer to each other perform optical lens blanks. Clamping and fixing, when the clamping block 208 is unstable in clamping the optical lens blank, the rotating knob 304 can be turned, and the rotating knob 304 drives the screw 303 to rotate. Since the screw 303 passes through the clamping block 208 through the threaded hole 301, the screw 303 drives the limit plate 305 fixedly connected at one end to move. Since the limit plate 305 is embedded in the locking block 306 through the limit groove 308, and one end of the spring 302 is connected to the clamping block 208, and the other end is fixedly connected to the locking block 306, the screw 303 drives the locking block 306 to move through the limit plate 305, and when the locking block 306 is tightly fitted with the optical lens blank, it can be clamped and fixed.
