Description

Technical Field

[0001] The invention belongs to the technical field of eyeglass lens processing machinery, and in particular relates to a cross-cutting machine for lens processing. Background Art

[0002] A lens cross-cutting machine is a device used to cut lenses. It is used to cut rolled raw materials into sheets that are close to the lens contour. For example, the Chinese invention patent with announcement number CN219987717U describes an automatic lens slicing and unscrambling machine. It cuts the raw materials horizontally and vertically, and then uses a mechanical transmission structure to automatically produce them, greatly improving production efficiency.

[0003] When the cutting tool is slightly worn, it needs to be removed for sharpening. When the tool is severely worn and still cannot meet the cutting requirements after multiple sharpenings, or when the tool has reached the end of its service life, it should be replaced with a new tool in time. The problems existing in the existing technology are:

[0004] The tool is installed by bolts. The screws need to be tightened one by one during installation and loosened one by one during disassembly. This process takes a lot of time and affects work efficiency. In addition, the lens cross-cutting machine will generate certain vibrations during operation. Long-term vibration may cause the screws to gradually loosen. Regular inspection and tightening of the screws are required, which increases the maintenance workload. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art.

[0006] The present application provides a cross-cutting machine for lens processing, comprising a frame, an unwinding mechanism, a loading structure, a longitudinal cutting mechanism, a longitudinal transfer mechanism, several transverse transfer structures and several cross-cutting mechanisms. The cross-cutting mechanism comprises a pair of vertical plates standing upright on both sides of the transverse transfer structure, a tool holder and a tool are installed for lifting between the pair of vertical plates, the tool is installed on the tool holder through a plug-in structure, and longitudinally extending tool grooves and an opening and closing structure for opening / closing the front side of the middle part of the tool groove are provided on the inner walls of the opposite sides of the pair of vertical plates.

[0007] The opening and closing structure includes a flip groove arranged on the outer side of the middle part of the vertical plate, the front and rear ends of the flip groove are connected, and the front end is L-shaped and connected to the inner wall of the vertical plate. A flip plate and a sliding pressure plate are installed in the flip groove, and one end of the flip plate is hinged to the rear end of the flip groove through a rotating shaft. The sliding pressure plate is slidably installed on the flip plate, and the outer end is an L-shaped bent end and extends toward the inner wall of the vertical plate. The relative movement of the flip plate and the sliding pressure plate is controlled by the driving structure, and the flip plate and the flip groove are fixed to each other by a locking structure, and the locking / unlocking of the locking structure is controlled by the sliding pressure plate.

[0008] The opening and closing structure also includes a pair of transverse grooves arranged on the sliding pressure plate, each transverse groove is slidably installed with a limiting member, the inner end of each limiting member is fixedly connected to the flip plate, and the outer end is fixed with a retaining ring with a cross-sectional width greater than the width of the transverse groove.

[0009] The limiting member is a bolt, which includes a threaded portion and a retaining ring. The threaded portion is connected to the flip plate through a screw hole, and the cross-sectional area of ​​the nut portion is greater than the width of the transverse groove.

[0010] The plug-in structure comprises a plurality of plug-in posts and a plurality of plug-in holes. The plug-in posts are perpendicular to the surface of the tool and fixed on the tool holder. The plug-in holes are arranged on the tool and plugged with the plug-in holes.

[0011] The driving structure includes a transmission groove arranged on the sliding pressure plate and a cam rotatably installed on the outer wall of the flip plate. The cam includes a distal end and a proximal end. When the cam is rotated so that its distal end and proximal end contact the front side / rear side and the rear side / front side of the transmission groove respectively, the sliding pressure plate is driven to complete the forward / backward movement. A hexagonal groove is provided on the cam.

[0012] The driving structure also includes a floating rod installed on the outer wall of the flip plate through a floating hole and a spring. The outer end of the floating rod is fixed to the cam, and the spring is arranged between the inner end of the floating rod and the inner end of the floating hole. Blocking blocks are provided on the outer sides of the upper and lower ends of the transmission groove.

[0013] The driving structure also includes an inner groove arranged on the inner side of the flip plate, which is connected to the floating hole through a through hole. A baffle is floatingly installed in the inner groove, and a connecting rod is slidingly installed in the through hole. The two ends of the connecting rod are respectively fixed to the baffle and the floating rod.

[0014] The locking structure includes a pair of card slots respectively arranged at the top and bottom ends of the flip groove, a vertical slot passing through the flip plate from top to bottom, a pair of connecting slots arranged at the front side of the flip plate and connected to the vertical slots, and an insertion rod floatingly installed in the vertical slot, the outer end of which can be plugged into the inner end of the corresponding card slot and provided with a tension spring. A linkage structure is installed in each connecting groove, and the linkage structure is used to control the corresponding insertion rod to be inserted into the card slot when the inner wall of the bent end approaches the front side of the flip plate.

[0015] The linkage structure includes a fixed block fixedly installed on the inner wall of the bent end, a mounting slot that passes through the inserted rod on the left and right sides, and a floating block floatingly installed in the mounting slot and the connecting slot. The inner wall of the floating block is hinged with a connecting rod, and the other end of the connecting rod is hinged to the side wall of the mounting slot close to the corresponding card slot.

[0016] The beneficial effects of the present invention are as follows:

[0017] Use an Allen wrench to insert the Allen groove and then press the cam. After the cam disengages from a pair of blocking blocks, rotate the Allen wrench to flip the distal end of the cam toward the bent end of the sliding pressure plate, and cooperate with the transmission groove to push the sliding pressure plate to slide toward the front end. The bent end is disengaged from the contact with the front end of the flip plate. The tension spring resets to disengage a pair of rods from the corresponding slots. Then, the sliding pressure plate and the flip plate are moved to move the bent end of the sliding pressure plate out of the flip slot. The front side of the middle of the tool slot is open, and the tool can be moved away from the tool holder until the sockets are disengaged from the posts. The tool can then be removed. The tool can be quickly disassembled by simply rotating the two cams 180° with a Allen wrench, which saves time and effectively improves work efficiency.

[0018] When installing the tool, align the various sockets on the tool with the various pins on the tool holder, then bring the tool close to the tool holder so that the pins are inserted into the corresponding sockets, and the tool cannot move up and down relative to the tool holder. Then, pull the sliding pressure plate and the flip plate to make the bent end of the sliding pressure plate enter the flip groove, and then use the Allen wrench to insert the Allen wrench into the Allen groove and press the cam. After the cam disengages from a pair of blocking blocks, rotate the Allen wrench to make the proximal end of the cam flip toward the bent end of the sliding pressure plate, and cooperate with the transmission groove to push the sliding pressure plate to slide to the rear end until the bent end contacts the front end of the flip plate. Each fixed block cooperates with each floating block and the corresponding connecting rod to make the outer end of each connecting rod insert into the corresponding slot, and then remove the Allen wrench. The two sides of the cam are pressed against the pair of blocking blocks and cannot be rotated again. In this way, the positions of the flip plate and the sliding pressure plate are fixed, ensuring that the tool is firmly installed and can prevent loosening, reducing maintenance workload.

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0028] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] The cross-cutting machine for lens processing provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1 to 6As shown, an embodiment of the present application provides a cross-cutting machine for lens processing, including a frame 100, a rewinding mechanism 200, a loading structure 300, a longitudinal cutting mechanism 400, a longitudinal transfer mechanism 500, a plurality of transverse transfer structures 600 and a plurality of cross-cutting mechanisms 1. The cross-cutting mechanism 1 includes a pair of vertical plates 11 upright on both sides of the transverse transfer structure 600, a tool holder 12 and a tool 13 are installed between the pair of vertical plates 11 for lifting and lowering, and the tool 13 is installed on the tool holder 12 through a plug-in structure 2. The inner walls of the opposite sides of the pair of vertical plates 11 are provided with a longitudinally extending tool groove 14 and an opening and closing structure 3 for opening / closing the front side of the middle part of the tool groove 14.

[0032] Furthermore, the opening and closing structure 3 includes a flip groove 31 arranged on the outer side of the middle part of the vertical plate 11, the front and rear ends of the flip groove 31 are connected, and the front end is L-shaped and connected to the inner wall of the vertical plate 11. A flip plate 32 and a sliding pressure plate 33 are installed in the flip groove 31, and one end of the flip plate 32 is hinged to the rear end of the flip groove 31 through a rotating shaft. The sliding pressure plate 33 is slidably installed on the flip plate 32, and the outer end is an L-shaped bent end 331 and extends toward the inner wall of the vertical plate 11. The flip plate 32 and the sliding pressure plate 33 are controlled to move relative to each other by the driving structure 4, and the flip plate 32 and the flip groove 31 are fixed to each other by the locking structure 5, and the sliding pressure plate 33 controls the locking / unlocking of the locking structure 5.

[0033] Furthermore, the plug-in structure 2 includes a plurality of plug posts 21 and a plurality of plug holes 22 . Each plug post 21 is perpendicular to the surface of the tool 13 and fixed on the tool holder 12 . Each plug hole 22 is provided on the tool 13 and plugged into each plug hole 22 .

[0034] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when installing the tool 13, the respective sockets 22 on the tool 13 are aligned with the corresponding pins 21 on the tool holder 12, and then the tool 13 is brought close to the tool holder 12, and the pins 21 are inserted into the corresponding sockets 22 until the tool 13 and the adjacent sides of the tool holder 12 are in contact, and then the flip plate 32 and the sliding pressure plate 33 are manually controlled to flip into the flip groove 31 along the axis of the rotating shaft until the bent end 331 is completely inserted into the flip groove 31, and then the driving operation is operated. The dynamic structure 4 controls the sliding of the sliding pressure plate 33 so that the inner side wall of the bent end 331 is pressed against the outer end of the flip plate 32. At this time, the inner side wall of the bent end 331 is connected to the upper and lower sections of the front side wall of the knife groove 14, forming the front side wall of the knife groove 14. At this time, the two ends of the tool holder 12 and the tool 13 are also in sliding and frictional contact with the inner side wall of the flip plate 32 respectively. At the same time, the bent end 331 at the outer end of the sliding pressure plate 33 drives the locking structure 5 to fix the flip plate 32 and the flip groove 31 to each other, completing the installation of the tool 13.

[0035] When removing the tool 13, the driving structure 4 is controlled to slide the sliding pressure plate 33 toward the front end relative to the flip plate 32, and the bent end 331 is separated from the contact with the front end of the flip plate 32. At the same time, the locking structure 5 releases the fixation of the flip plate 32 and the flip groove 31. The flip plate 32 and the sliding pressure plate 33 can be flipped around the axis of the rotating shaft, so that the bent end 331 is separated from the flip groove 31 and away from the tool groove 14. At this time, the middle part of the front side of the tool groove 14 is opened, and the tool 13 is moved away from the tool holder 12 until the sockets 22 are separated from the pins 21, and the tool 13 is removed.

[0036] Example 2:

[0037] like Figures 3 to 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the opening and closing structure 3 also includes a pair of transverse grooves 34 arranged on the sliding pressure plate 33, and a limiting member is slidably installed in each transverse groove 34. The inner end of each limiting member is fixedly connected to the flip plate 32, and the outer end is fixedly provided with a retaining ring 36 whose cross-sectional width is greater than the width of the transverse groove 34.

[0038] Furthermore, the limiting member is a bolt, which includes a threaded portion and a retaining ring 36 . The threaded portion is connected to the flip plate 32 through a screw hole, and the cross-sectional area of ​​the nut portion is greater than the width of the transverse groove 34 .

[0039] In this embodiment of the present application, due to the adoption of the above-mentioned structure, each transverse groove 34 is parallel to the flip groove 31. When each sliding pressure plate 33 slides relative to the corresponding flip plate 32, each transverse groove 34 slides along the extension direction of the flip groove 31 and each transverse groove 34, and the threaded portion moves relatively from one end of the transverse groove 34 to the other end. The inner end face of the nut portion slides and rubs against the outer side wall of the sliding pressure plate 33 to prevent the sliding pressure plate 33 from separating from the flip plate 32. In order to improve the firmness, and since the bolt does not need to be removed when disassembling the tool 13, the outer wall of the threaded portion can be welded to the outer side wall of the flip plate 32 to ensure the firmness of the connection between the threaded portion and the screw hole, and the installation firmness of the tool 13 is guaranteed.

[0040] Example 3:

[0041] like Figures 3 to 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the driving structure 4 includes a transmission groove 41 arranged on the sliding pressure plate 33, and a cam 42 rotatably installed on the outer wall of the flip plate 32. The cam 42 includes a distal end 421 and a proximal end 422. When the cam 42 is rotated so that its distal end 421 and proximal end 422 are in contact with the front side / rear side and the rear side / front side of the transmission groove 41 respectively, the sliding pressure plate 33 is driven to complete the forward / backward movement. A hexagonal groove 43 is provided on the cam 42.

[0042] Furthermore, the driving structure 4 also includes a floating rod 46 that is floatingly mounted on the outer wall of the flip plate 32 through a floating hole 44 and a spring 45. The outer end of the floating rod 46 is fixed to the cam 42, and the spring 45 is arranged between the inner end of the floating rod 46 and the inner end of the floating hole 44. The outer sides of the upper and lower ends of the transmission groove 41 are provided with blocking blocks 47.

[0043] Furthermore, the driving structure 4 also includes an inner groove 48 arranged on the inner side of the flip plate 32, the inner groove 48 is connected to the floating hole 44 through a through hole 49, a baffle 410 is floatingly installed in the inner groove 48, and a connecting rod 411 is slidingly installed in the through hole 49, and both ends of the connecting rod 411 are fixed to the baffle 410 and the floating rod 46 respectively.

[0044] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to control the sliding pressure plate 33 to move forward / backward, an inner hexagonal wrench is inserted into the hexagonal groove 43 and pressed, the floating rod 46 moves toward the inner end of the floating hole 44, the spring 45 is compressed and shortened, the baffle 410 is separated from the contact with the inner end of the inner groove 48, and at the same time, the two sides of the cam 42 are separated from the pair of blocking blocks 47, and then the inner hexagonal wrench is turned to rotate the cam 42 180 degrees about the axis of the floating rod 46, and the distal end 421 of the cam 42 is toward / away from the bent end 3 31, push the front / rear side wall of the transmission groove 41, and after completing the movement of the sliding pressure plate 33, disengage the hexagonal wrench from the hexagonal groove 43. The spring 45 releases the elastic potential energy to push the floating rod 46 to slide out of the floating groove. The two sides of the cam 42 are in contact with the pair of blocking blocks 47 again, and the baffle 410 is in contact with the inner end of the inner groove 48. In this way, the cam 42 is restricted by the pair of blocking blocks 47 and cannot rotate, which can ensure that the sliding pressure plate 33 cannot move again after sliding forward / backward, ensuring the firm installation of the tool 13.

[0045] Example 4:

[0046] like Figures 3 to 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the locking structure 5 includes a pair of card slots 51 respectively arranged at the top and bottom ends of the flip slot 31, a vertical slot 52 passing through the flip plate 32 from top to bottom, a pair of connecting slots 53 arranged on the front side of the flip plate 32 and connected to the vertical slot 52, and an insertion rod 55 floatingly installed in the vertical slot 52, the outer end of which can be plugged into the inner end of the corresponding card slot 51 and provided with a tension spring 54. A linkage structure 6 is installed in each connecting slot 53, and the linkage structure 6 is used to control the corresponding insertion rod 55 to be inserted into the card slot 51 when the inner wall of the bent end 331 approaches the front side of the flip plate 32.

[0047] Furthermore, the linkage structure 6 includes a fixed block 61 fixedly installed on the inner wall of the bent end 331, a mounting groove 62 passing through the insert rod 55 on the left and right, and a floating block 63 floatingly installed in the mounting groove 62 and the connecting groove 53. The inner wall of the floating block 63 is hinged with a connecting rod 64, and the other end of the connecting rod 64 is hinged to the side wall of the mounting groove 62 close to the corresponding card slot 51.

[0048] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the bent end 331 approaches the front end of the flip plate 32, each fixed block 61 enters the connecting groove 53, pushing each floating block 63 into the mounting groove 62, thereby driving each connecting rod 64 to push each insertion rod 55 to slide outward. When the inner side wall of the bent end 331 is tightly abutted against the front end of the flip plate 32, the inner end of each installation groove 62 is tightly abutted against the inward side wall of the corresponding fixed block 61, and the outer end of each insertion rod 55 is also inserted into the corresponding slot 51, the tension spring 54 between the pair of insertion rods 55 is stretched and deformed to store elastic potential energy;

[0049] When the bent end 331 moves away from the front end of the flip plate 32 , each fixing block 61 disengages from the corresponding connecting slot 53 , and the tension spring 54 releases elastic potential energy to pull the outer ends of a pair of insertion rods 55 out of the corresponding slot 51 , and each floating block 63 disengages from the corresponding installation slot 62 .

[0050] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved. For example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0051] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
