Description

Technical Field

[0001] The invention relates to the technical field of lens processing, in particular to an optical lens processing milling machine. Background Art

[0002] Optical lenses are optical elements made of transparent material with a partially spherical surface. Lenses are used in important fields such as astronomy, military, transportation, and medicine. Optical lens processing generally requires four steps: milling, fine grinding, polishing, and edging. Optical lens milling mainly involves the initial processing of the disc-shaped blank into a circular shape so that it can be ground into a circular arc surface. After the disc-shaped blank is placed on the workbench, the clamping block needs to be controlled to clamp the side edge of the blank, and then the tool will approach the blank during the rotation process, thereby milling one of the end faces of the blank. After one of the end faces of the blank is milled into a circular arc surface, the clamping block is released to release the clamping of the blank, the blank is turned so that the other end face of the blank faces the tool, and then the blank is clamped again, and then the other end face of the blank is milled to complete the milling process of the optical lens. It can be seen that both end faces of the existing optical lens blank need to be processed into circular arc surfaces, and the existing milling processing method is performed on the two end faces of the blank in sequence, which makes the existing optical lens milling efficiency low.

DETAILED DESCRIPTION

[0027] 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 explained below in conjunction with specific implementation methods.

[0028] like Figures 1 to 7 As shown, the present invention includes the following embodiments;

[0029] Embodiment 1:

[0030] An optical lens processing milling machine comprises a base 1 and a support leg 11 arranged at the bottom of the base 1; a collecting trough 12 is arranged at the center of the upper surface of the base 1; a discharge port 13 is arranged at the bottom of the collecting trough 12; a lower cylinder 2 is fixedly connected to the bottom of the collecting trough 12; an output end of the lower cylinder 2 is fixedly connected to a lower motor 21; an upper motor 31 is arranged just above the lower motor 21; the tail of the upper motor 31 is fixedly connected to an upper cylinder 3; the upper cylinder 3 is fixedly connected to the base 1 through a bracket 32 The output shafts of the upper motor 31 and the lower motor 21 are fixedly connected to the milling disc 4; the two milling discs 4 are close to each other and are arranged to form a curved surface; a plurality of electric push rods 51 are arranged around the central axis of the base 1 above the base 1; the output end of the electric push rod 51 is fixedly connected to a clamping block 52; the thickness of the clamping block 52 is less than the thickness of the blank; the clamping block 52 can clamp the side edge of the blank; the upper and lower milling discs 4 can simultaneously mill the end face of the clamped blank.

[0031] In this embodiment, an annular groove 14 is provided on the upper surface of the base 1; the annular groove 14 is located outside the collecting groove 12; the notch of the annular groove 14 is rotatably sealed and connected to the outer gear sleeve 5; the outer wall of the outer gear sleeve 5 is meshed with a gear 53; the center of the gear 53 is fixedly connected to the output shaft of the main motor 54; the outer wall of the main motor 54 is fixedly connected to the outer wall of the base 1; a vertical groove 55 is vertically provided on the inner side of the outer gear sleeve 5; a vertical block 56 is slidably connected in the vertical groove 55; the vertical block 56 is fixedly connected to the tail of the electric push rod 51.

[0032] In this embodiment, the lower surface of the vertical block 56 is connected to the lower inner wall of the vertical slot 55 via a first spring 57 ; the elastic force of the first spring 57 can drive the vertical block 56 to move upward along the vertical slot 55 .

[0033] In this embodiment, a folding sleeve 6 is sleeved on the outer wall of the first spring 57; the upper end of the folding sleeve 6 is fixedly connected to the lower surface of the vertical block 56, and the lower end is fixedly connected to the lower inner wall of the vertical groove 55; a first air hole 61 is provided inside the outer gear sleeve 5; the interiors of the two folding sleeves 6 are connected through the first air hole 61; the folding sleeve 6 is made of elastic material.

[0034] During operation, initially the lower main motor 54, the upper motor 31 and the lower motor 21 all stop rotating, the upper cylinder 3 drives the upper motor 31 and the upper milling disc 4 to move upward and out from the inner side of the outer gear sleeve 5, and the vertical block 56 is also in the upper limit position in the corresponding vertical slot 55. The vertical block 56 will drive the clamping block 52 at the output end of the electric push rod 51 to be located at the upper position on the inner side of the outer gear sleeve 5, so as to facilitate the loading of the blank. The staff will place the blank in the center position of the milling surface of the milling disc 4 at the upper position, and then the lower cylinder 2 will extend to drive the lower motor 21 and the milling disc 4 at the lower position to move upward. The milling disc 4 at the lower position will drive the blank to move upward during the upward movement until the blank moves to the inner side of multiple clamping blocks 52, and then control multiple electric push rods 51 to move simultaneously. The upper cylinder 3 is stretched and the upper motor 31 is moved downward. The upper motor 31 is moved downward. The upper milling disc 4 is moved downward until the upper milling disc 4 contacts the upper surface of the blank. The upper cylinder 3 continues to stretch, so that the upper milling disc 4 squeezes the blank downward and the blank is clamped. The clamping block 52 clamps the blank, and the downward movement of the clamping block 52 and the electric push rod 51 will drive the downward movement of the electric push rod 51 to drive the vertical block 56 to slide in the vertical groove 55 and squeeze the first spring 57, so that the first spring 57 is compressed and the folding sleeve 6 is compressed and expanded. The inner wall of the expanded folding sleeve 6 will move away from the first spring 57, so that the first spring 57 is smoothly compressed until the vertical block 56 moves to the middle section of the vertical groove 55. After the blank moves downward, it will be located in the middle section of the inner side of the outer gear sleeve 5, preparing for subsequent processing. The milling surface of the upper milling grinding disc 4 will contact the upper surface of the blank. In the process of extending the upper cylinder 3, the lower cylinder 2 will shorten, and the lower motor 21 and the lower milling grinding disc 4 will move downward with the downward movement of the blank until the blank stops. After stopping downward movement, keep the milling surface of the lower milling disc 4 in contact with the lower surface of the blank, then start the upper motor 31 and the lower motor 21 to rotate in the forward and same direction, control the main motor 54 to rotate in the opposite direction, and the upper cylinder 3 gradually extends during the rotation of the upper motor 31, so that the upper motor 31 drives the milling surface of the upper milling disc 4 to mill the upper surface of the blank, and the lower cylinder 2 extends during the rotation of the lower motor 21, so that the lower motor 21 drives the milling surface of the lower milling disc 4 to mill the lower surface of the blank. During the milling process of the blank, the blank may move up or down due to the different milling degrees of the upper and lower surfaces, or move up and down due to the milling vibration. During the up and down movement of the blank, the clamping block 52, the electric push rod 51 and the vertical block 56 will be driven to move up or down synchronously.The vertical block 56 is movably connected in the vertical groove 55 up and down, so that the blank can move in the vertical direction as the upper and lower surfaces are pressurized by milling, so as to ensure that the relative position of the outer wall of the blank and the clamping block 52 is constant, so that the stability of the lateral edge of the blank and the clamping block 52 is improved, and the smooth milling of the blank is ensured; the main motor 54 will drive the gear 53 to rotate during the rotation, and the gear 53 will mesh with the teeth on the outer wall of the outer gear sleeve 5. Therefore, the rotation of the outer gear sleeve 5 will drive the vertical block 56, the electric push rod 51 and the blank to rotate, and the rotation direction of the blank is opposite to that of the milling disc 4. The milling surface of the milling disc 4 can be a concave curved surface or a convex curved surface. , in this way, the preliminary milling and grinding requirements of different blanks are met. The distance element between the two milling and grinding discs 4 can be controlled to measure the remaining thickness of the blank. This is a prior art and will not be elaborated on here. During the milling and grinding process, the cutting fluid will be sprayed onto the blank, and the machining debris and cutting fluid on the blank will be thrown toward the inner wall of the outer gear sleeve 5 under the centrifugal force generated by the rotation of the blank. The outer gear sleeve 5 shields the debris and cutting fluid during the machining process, so that the debris flows into the collection tank 12 with the cutting fluid and is finally discharged along the discharge port; after the blank is milled, the main motor 54, the upper motor 31 and the lower motor 21 are controlled to stop rotating, and the upper cylinder 3 is controlled to shorten. During the shortening process of the upper cylinder 3, the upper motor 3 is driven 1 and the upper milling and grinding disc 4 move up. During the upward movement, the milling and grinding disc 4 will be out of contact with the blank. As the upper milling and grinding disc 4 moves up, the first spring 57 will push the vertical block 56 to move up. During the upward movement of the vertical block 56, the electric push rod 51, the clamping block 52 and the blank will be driven to move up. During the upward movement of the vertical block 56, the folding sleeve 6 will be pulled. The expanded folding sleeve 6 begins to tighten. After the inner wall of the folding sleeve 6 is tightened, it contacts with the first spring 57 and generates friction, thereby constraining the expansion of the first spring 57 and reducing the expansion speed of the first spring 57, so that the vertical block 56 can slowly move up in the vertical slot 55, so that the blank will move up slowly, avoiding the blank from moving up quickly to throw out debris and cutting fluid. The inertia of the blank is reduced to prevent the blank from being separated from the inner side of the clamping block 52. The inner sides of the two folding sleeves 6 are connected through the first air hole 61, so that the multiple vertical blocks 56 move up in unison. During the slow upward movement of the blank, the outer gear sleeve 5 will rotate under the influence of the remaining kinetic energy, so that the blank rotates inside the outer gear sleeve 5 to throw away the cutting fluid and debris. Finally, after the vertical block 56 and the blank move up to the limit position, the processed blank is supported by hand, and the electric push rod 51 is shortened to release the clamping of the blank, so that the blank can be smoothly removed and the next blank can be milled, and this process is repeated; the blank after milling will also undergo fine grinding, polishing, edge grinding and other processes to form an optical lens;

[0035] The present invention arranges milling discs 4 on the upper and lower surfaces of the blank respectively, so that the milling discs 4 can simultaneously mill the upper and lower surfaces of the blank. Compared with the existing method of sequentially milling the two end surfaces of the blank, the processing efficiency of the optical lens is greatly improved.

[0036] The present invention controls the position of the blank inside the outer gear sleeve 5 during the milling process, thereby throwing out and collecting the debris and cutting fluid generated during the milling process to ensure the cleanliness of the processing environment. In addition, by controlling the blank to move upward after the milling is completed, it is convenient to load and unload the blank, making the milling machine more convenient to use.

[0037] Embodiment 2:

[0038] The milling disc 4 is composed of a single base disc 41 in the center and multiple milling rings 42 around it; the multiple milling rings 42 are nested with each other and movably sealed; the innermost milling ring 42 is movably sealed on the outer wall of the base disc 41; the inner wall of the milling ring 42 is provided with a movable groove 43; the movable block 44 is movably connected in the movable groove 43; the innermost movable block 44 is fixedly connected to the outer wall of the base disc 41, and the other movable blocks 44 are fixedly connected to the outer walls of the corresponding milling rings 42; the surfaces of the single base disc 41 and the multiple milling rings 42 close to the clamping block 52 are combined to form a curved milling surface.

[0039] In this embodiment, the base plate 41 is fixedly connected to the locking plate 7 on the side facing away from the milling surface; the outer wall of the locking plate 7 is provided with a locking groove 71; the locking bar 72 is movably connected in the locking groove 71; the locking bar 72 is connected to the bottom of the locking groove 71 by a second spring 73; the end of the locking bar 72 can be inserted into the movable groove 43 on the inner wall of the offset milling ring 42; the locking bar 72 is fixedly connected to the shift block 74 on the side facing away from the milling surface.

[0040] In this embodiment, the movable groove 43 is annular in shape; the end face of the milling ring 42 away from the milling surface is fixedly connected to the block 45; after the locking bar 72 is located at the end face of the corresponding milling ring 42 away from the milling surface, the locking bar 72 can limit the corresponding block 45.

[0041] In this embodiment, a magnetic strip 33 is vertically arranged inside the bracket 32 ​​; the clamping block 45 is made of magnetic material; and the clamping block 45 is magnetically attracted by the magnetic strip 33 .

[0042] The locking cam 72 is pressed against the locking cam 74 so that the locking cam 72 is in a state of being moved away from the locking cam 74, thereby releasing the locking cam 72 from the locking cam 74. If locking sill 752 snap on the action of locking plate 74?, then lock core 71 is in the state of being firmly locked to lock core 71, and locking plate 71 is in the state of being firmly locked to lock core 71.

[0043] Then, the blank on the upper surface of the lower milling disc 4 is controlled to move up to the inner side of the clamping block 52, the clamping block 52 is controlled to approach the blank and clamp the side edge of the blank, the upper milling disc 4 is controlled to move down to squeeze the blank downward, and the lower milling disc 4 will move down during the shortening process of the lower cylinder 2 until the blank moves to the middle position of the inner side of the outer gear sleeve 5, the upper motor 31, the lower motor 21 and the main motor 54 are started to rotate, the two milling discs 4 will rotate, and the rotation direction of the blank is opposite to that of the milling disc 4 to ensure the milling effect During the rotation of the upper motor 31 and the lower motor 21, the corresponding fixed lock plate 7 will be driven to rotate, and during the rotation of the lock plate 7, the fixed base plate 41 will be driven to rotate, and during the rotation of the base plate 41 and the lock plate 7, the lock bar 72 will be driven to rotate. For the convenience of subsequent description, the milling ring 42 that does the milling work is called the working milling ring 42, and the milling ring 42 that does not do the milling work is called the non-working milling ring 42. During the rotation of the lock bar 72 around the central axis of the lock plate 7, the working milling ring 42 will be away from the clamping block 52. The block 45 contacts with the locking bar 72, and the block 45 can be an iron block. After the locking bar 72 contacts with the block 45, the block 45 will be driven to move synchronously. As the locking bar 72 rotates around the locking disk 7, the block 45 will drive the corresponding working milling ring 42 to rotate. The milling surface composed of the working milling ring 42 and the base disk 41 mills the end surface of the blank, while the block 45 on the non-working milling ring 42 cannot contact with the rotating locking bar 72, and the block 45 on the non-working milling ring 42 will also be attracted by the magnetic strip 33, so that The non-working milling ring 42 will not rotate due to the friction of the working milling ring 42, and the end of the locking bar 72 will move in the annular movable groove 43. The locking bar 72 will generate centrifugal force during the rotation of the lock plate 7, so that the end of the locking bar 72 is further stuck in the movable groove 43 on the inner side wall of the corresponding non-working milling ring 42, so that the non-working milling ring 42 is more stable when not participating in the milling, and the working milling ring 42 is more stable for milling after the locking bar 72 is locked; in this way, the milling work of the two end faces of the blank is completed;

[0044] When it is necessary to restore the milling disc 4 to the state before adjustment, it is only necessary to move the shifting block 74 closer to the locking disc 7 again, so that the locking bar 72 is moved out of the movable groove 43 on the inner wall of the non-working milling ring 42, and the non-working milling ring 42 is pushed to move closer to the clamping block 52, so that all the milling rings 42 and the base disc 41 close to the clamping block 52 form a curved complete surface, i.e., a milling surface;

[0045] In this embodiment, the milling ring 42 on the outer wall of the base plate 41 is adjusted to move and lock, so that the milling plate 4 can be adaptively adjusted according to the shape of the blank, so that the milling plate 4 can be suitable for blanks of different specifications, expanding the milling range of the blank;

[0046] This embodiment controls the milling ring 42 that does not participate in the milling so as not to rotate along with the rotation of the base plate 41, thereby avoiding friction between the milling ring 42 that does not participate in the milling and the surrounding clamping blocks 52 and the electric push rod 51, thereby protecting the milling ring 42 that does not participate in the milling and the surrounding parts, thereby improving the stability of the milling machine.

[0047] The magnetic strip 33 in this embodiment can be used alone to support the milling disc 4 to ensure the magnetic attraction effect;
