[0001] The utility model relates to the technical field of optical element cutting, in particular to a device for cutting optical element blank bars. Background Art

[0002] Optical parts, also known as optical elements, are the basic components of optical systems. Most optical parts play the role of imaging, such as lenses, prisms, reflectors, etc. In addition, there are some parts that play special roles in optical systems (such as light splitting, image transmission, filtering, etc.), such as gratings, filters, gratings for optical fiber parts, etc. Holographic lenses, gradient refractive index lenses, binary optical elements, etc. are new optical parts that have appeared in the past 10 to 20 years.

[0003] At present, the utility model with publication number CN209566351U proposes the cutting and forming of rod materials in optical parts, and provides a blank forming of optical parts with compact structure and automatic discharging.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: an optical element blank bar cutting device, comprising a support table 1 and a cutting box 2, the bottom of the support table 1 is welded with legs, and a cutting knife 9 is arranged at the bottom of the cutting box 2. Specifically, a pulley transmission group is arranged in the cutting box 2, and then a driving motor is installed on the outside of the cutting box 2, and the driving motor is connected to the cutting knife 9 through the belt transmission group, and the cutting knife 9 is a disc knife.

[0025] In the present technical solution, the upper end surface of the support table 1 is provided with a first double-headed clamp 3 and a second double-headed clamp 4 located at the front end of the first double-headed clamp 3. The gap between the first double-headed clamp 3 and the second double-headed clamp 4 is the cutting position. The first double-headed clamp 3 is used to clamp the optical element blank bar, and the second double-headed clamp 4 is used to clamp the part that is detached after cutting. Therefore, when the second double-headed clamp 4 is controlled to be released after cutting, the small section of bar formed after cutting will fall off. This setting can improve the cutting accuracy and avoid the problem of small sections of bar flying out after cutting.

[0026] Specifically, the first double-head clamp 3 includes a first vertical plate 31, a first transmission shaft 32, a first V-shaped clamp 33 and a synchronous control group 34. There are two first vertical plates 31 and the bottom is welded to the upper end surface of the support platform 1. The two first vertical plates 31 are parallel. A first transmission shaft 32 is connected through one side of the first vertical plate 31. The first transmission shaft 32 and the first vertical plate 31 are slidably connected. One first vertical plate 31 corresponds to one first transmission shaft 32. The first transmission shafts 32 on the two first vertical plates 31 are coaxially arranged. The opposite ends of the two first transmission shafts 32 are welded with first V-shaped clamps 33. The synchronous control group 34 is connected to the two first vertical plates 31 and is used to control the synchronous opposite and reverse sliding of the two first transmission shafts 32. When the two first transmission shafts 32 move synchronously towards each other, the first V-shaped clamp 33 is used to clamp the blank bar.

[0027] The above-mentioned synchronous control group 34 includes a driving shaft 341, a left thread sleeve 342 and a right thread sleeve 343. The driving shaft 341 is a double-headed screw structure. The driving shaft 341 passes through the two first vertical plates 31 and is rotatably arranged. The driving shaft 341 is located below the first V-shaped clamping plate 33. The divergent ends of the two first transmission shafts 32 are welded with connecting arms 321. The left thread sleeve 342 and the right thread sleeve 343 are sleeved on the driving shaft 341 and are screwed together. The threads in the left thread sleeve 342 and the right thread sleeve 343 have opposite rotation directions. One end of the connecting arm 321 on the two first transmission shafts 32 is welded to the left thread sleeve 342 and the right thread sleeve 343 respectively. Therefore, when the driving shaft 341 is controlled to rotate, the two first transmission shafts 32 can be controlled to move synchronously.

[0028] In this embodiment, the second double-headed clamp 4 includes a second vertical plate 41, a second transmission shaft 42 and a second V-shaped clamp 43. The number of the second vertical plates 41 is two, and the bottom and the upper end surface of the support platform 1 are welded and connected. The two second vertical plates 41 are also arranged in parallel. The number of the second transmission shafts 42 is two, and they are respectively slidably matched with the two second vertical plates 41. The two second transmission shafts 42 are coaxial and have second V-shaped clamps 43 welded at the opposite ends. The two second V-shaped clamps 43 are used to clamp the parts that are detached after cutting. A linkage control component 7 is arranged between the first double-headed clamp 3 and the second double-headed clamp 4. Under the action of the linkage control component 7, the two first V-shaped clamps 33 and the two second V-shaped clamps 43 open and close synchronously with different amplitudes. That is to say, when the two first V-shaped clamps 33 are slightly loose, the two second V-shaped clamps 43 are in a greatly loosened state. This arrangement can save cost investment and improve the efficiency of material cutting after cutting.

[0029] The linkage control member 7 comprises a connecting rod 71 and a return spring 72. A support rod 311 near one end is welded on the outer side of the first vertical plate 31. One end of the connecting rod 71 is hingedly connected to one end of the support rod 311 and both sides thereof are connected to the first transmission shaft 32 for rotation and sliding. Specifically, a through hole can be provided on the outer peripheral wall of the first transmission shaft 32, a limit axis is welded in the through hole, and then a waist-shaped hole sleeved on the outside of the limit axis is provided on the rod body of the connecting rod 71. When the first transmission shaft 32 moves axially, the connecting rod 71 will swing passively. A baffle plate 421 located on the outer side of the second vertical plate 41 is fixedly sleeved on the second transmission shaft 42. The return spring 72 is sleeved on the second transmission shaft 42 and located between the baffle plate 421 and the second vertical plate 41. The function of the return spring 72 is to apply an elastic thrust to the second transmission shaft 42 for outward movement. One end of the second transmission shaft 42 is against one side of the connecting rod 71. When the connecting rod 71 swings inward, it will push the second transmission shaft 42 to slide inward.

[0030] A portal frame 5 is fixedly arranged on the top of the support platform 1, and a lifting rod 8 is fixedly connected to the top of the portal frame 5. The lifting rod 8 can be one of an oil cylinder, an air cylinder and an electric telescopic rod. The cutting box 2 is located in the portal frame 5 and its top is fixedly connected to the output shaft of the lifting rod 8. The cutting knife 9 is located directly above the cutting position. The cutting knife 9 can cut and process the bar material passing through the cutting position when it moves up and down. There is no need for manual feeding, which is safer and more labor-saving.

[0031] A material leakage window 6 is provided on the support table 1 below the second double-head clamp 4. When the small sections of rod material formed after the above cutting fall, they will pass through the material leakage window 6. A water tank 101 is provided below the support table 1 below the material leakage window 6. When the small sections of rod material fall into the water tank 101, the chips adsorbed on the rod material can be washed away by the impact of the water, thereby improving the cleanliness.

[0032] In this embodiment, an adjusting shaft 422 is screwed onto one end of the second transmission shaft 42, and an external hexagonal head is welded to the outer head of the adjusting shaft 422. One end of the adjusting shaft 422 is abutted against one side of the connecting rod 71. When the adjusting shaft 422 is controlled to rotate, the exposed length of the adjusting shaft 422 relative to the second transmission shaft 42 can be adjusted. This arrangement adjusts the extrusion pressure of the second V-shaped clamp 43 on a small section of the rod, and can also facilitate the processing of rods with different outer diameters.

[0033] In this embodiment, a filter screen 1011 is provided in the water tank 101. The filter screen 1011 has the function of preventing the cut small sections of the bar material from sinking to the bottom, making it easy to take out.

[0034] Working principle: 1. Preparation: Pour clean water into the water tank 101, control the cutting knife 9 to be at the highest point, and then manually control the driving shaft 341 to rotate. The left thread sleeve 342 and the right thread sleeve 343 will drive the two first transmission shafts 32 to move in the opposite direction, and the two first V-shaped clamps 33 will open slightly. When the two connecting rods 71 ​​swing outward, the two second V-shaped clamps 43 will open greatly under the push of the reset spring 72.

[0035] 2. Loading: Insert the blank bar of the optical element from one end between the two first V-shaped clamps 33, and then push the blank bar so that the part to be cut is located between the two second V-shaped clamps 43, and then control the driving shaft 341 to rotate in the opposite direction, the two first transmission shafts 32 move in opposite directions, and the two connecting rods 71 ​​swing in opposite directions. When the two first V-shaped clamps 33 clamp the bar, the connecting rod 71 pushes the second transmission shaft 42 so that the two second V-shaped clamps 43 clamp the part to be separated.

[0036] 3. Cutting: Start the cutting box 2, the cutting knife 9 rotates, and the lifting rod 8 is controlled to push, and the cutting knife 9 descends and enters the cutting position for cutting.

[0037] 4. Unloading: Control the cutting box 2 to withdraw, and then control the driving shaft 341 to rotate. At this time, the two first V-shaped clamps 33 are slightly loose, and the blank bar material will not fall, while the two second V-shaped clamps 43 are greatly opened, and the cut small sections of the bar material will directly fall into the water tank 101.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
