[0003] When the cutting tool is slightly worn, the cutting tool needs to be removed for edge grinding. When the tool is severely worn and still cannot meet the cutting requirements after multiple edge grindings, or when the tool has reached its service life, a new tool should be replaced in a timely manner. The problems existing in the prior art are as follows:

[0004] The tool is installed by bolts. When installing, the screws need to be tightened one by one, and when disassembling, the screws need to be loosened one by one. This process takes a lot of time and affects work efficiency. Moreover, the lens horizontal cutting machine will generate certain vibrations during operation, and the long-term vibrations may cause the screws to gradually loosen, requiring regular inspection and tightening of the screws, increasing the maintenance workload.

It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0029] The following will, with reference to the accompanying drawings, explain in detail the cross - cutting machine for lens processing provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0030] Embodiment 1:

[0031] As Figures 1 to 6As shown in the figure, an embodiment of the present application provides a horizontal cutting machine for lens processing, which includes a frame 100, a unwinding mechanism 200, a feeding structure 300, a longitudinal cutting mechanism 400, a longitudinal transfer mechanism 500, a plurality of transverse transfer structures 600, and a plurality of transverse cutting mechanisms 1. The transverse cutting mechanism 1 includes a pair of vertical plates 11 standing 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 in a lifting manner. The tool 13 is installed on the tool holder 12 through a plugging structure 2. Longitudinally extending tool slots 14 and an opening / closing structure 3 for opening / closing the front side of the middle part of the tool slot 14 are provided on the inner walls of the opposite sides of the pair of vertical plates 11.

[0032] Furthermore, the opening / closing structure 3 includes a flipping groove 31 provided on the outer side of the middle part of the vertical plate 11. Both the front and rear ends of the flipping groove 31 are penetrated, and the front end is connected to the inner side wall of the vertical plate 11 in an L shape. A flipping plate 32 and a sliding pressing plate 33 are installed in the flipping groove 31. One end of the flipping plate 32 is hinged to the rear end of the flipping groove 31 through a rotating shaft. The sliding pressing plate 33 is slidably installed on the flipping plate 32, and the outer end is a bent end 331 in an L shape and extends towards the inner side wall of the vertical plate 11. The relative movement between the flipping plate 32 and the sliding pressing plate 33 is controlled by a driving structure 4. The flipping plate 32 and the flipping groove 31 are fixed to each other through a locking structure 5, and the locking structure 5 is locked / unlocked by the sliding pressing plate 33.

[0033] Furthermore, the plugging 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 is fixed on the tool holder 12, and each plug hole 22 is provided on the tool 13 and is plugged with each plug post 21.

[0034] In this embodiment of the present application, due to the adoption of the above structure, when installing the tool 13, align each plug hole 22 on the tool 13 with the corresponding plug post 21 on the tool holder 12, and then move the tool 13 close to the tool holder 12. Each plug post 21 is inserted into the corresponding plug hole 22 until the adjacent side surfaces of the tool 13 and the tool holder 12 are in contact. Then manually control the flipping plate 32 and the sliding pressing plate 33 to flip into the flipping groove 31 around the axis of the rotating shaft until the bent end 331 completely enters the flipping groove 31. Then operate the driving structure 4 to control the sliding of the sliding pressing plate 33 so that the inner side wall of the bent end 331 abuts against the outer end of the flipping plate 32. At this time, the inner side wall of the bent end 331 is connected to the upper and lower segments of the front side wall of the tool slot 14 to form the front side wall of the tool slot 14. At the same time, the two ends of the tool holder 12 and the tool 13 also respectively have sliding friction contact with the inner side wall of the flipping plate 32. At the same time, the bent end 331 at the outer end of the sliding pressing plate 33 drives the locking structure 5 to fix the flipping plate 32 and the flipping groove 31 to each other, completing the installation of the tool 13.

[0035] When disassembling the cutting tool 13, the driving structure 4 is manipulated to slide the sliding pressing plate 33 forward relative to the flipping plate 32, so that the bent end 331 disengages from the contact with the front end of the flipping plate 32. At the same time, the locking structure 5 releases the fixation of the flipping plate 32 and the flipping groove 31. The flipping plate 32 and the sliding pressing plate 33 can be flipped around the axis of the rotating shaft, so that the bent end 331 disengages from the flipping groove 31 and moves 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 cutting tool 13 is moved away from the tool rest 12 until each jack 22 is separated from each plug post 21, and then the cutting tool 13 is disassembled.

[0036] Embodiment 2:

[0037] As Figures 3 to 6 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, the opening and closing structure 3 further includes a pair of transverse grooves 34 provided on the flipping plate 32. A restricting member 35 is slidably installed in each transverse groove 34. The inner ends of the restricting members 35 are fixedly connected to the flipping plate 32, and a retaining ring 36 with a cross-sectional width greater than the width of the transverse groove 34 is fixedly provided at the outer ends.

[0038] Furthermore, the restricting member 35 is a bolt. The bolt includes a threaded portion and a retaining ring 36. The threaded portion is connected to the flipping plate 32 through a threaded 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 structure, each transverse groove 34 is parallel to the flipping groove 31. When each sliding pressing plate 33 slides relative to the corresponding flipping plate 32, each transverse groove 34 slides along the extending direction of the flipping groove 31 and each transverse groove 34. The threaded portion relatively moves from one end of the transverse groove 34 to the other end, and the inner end surface of the nut portion slides in friction with the outer side wall of the sliding pressing plate 33 to prevent the sliding pressing plate 33 from disengaging from the flipping plate 32. To improve the firmness, and when disassembling the cutting tool 13, it is not necessary to disassemble this bolt. The outer wall of the threaded portion and the outer side wall of the flipping plate 32 can be welded to ensure the connection firmness between the threaded portion and the threaded hole, and the installation firmness of the cutting tool 13 is guaranteed.

[0040] Embodiment 3:

[0041] As Figures 3 to 6 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, the driving structure 4 includes a transmission groove 41 provided on the sliding pressing plate 33 and a cam 42 rotatably installed on the outer side wall of the flipping 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 rear side / front side of the transmission groove 41 respectively, the sliding pressing plate 33 is driven to complete forward / backward movement. A hexagonal groove 43 is provided on the cam 42.

[0042] Further, the driving structure 4 further includes a floating rod 46 that is floatingly installed on the outer side wall of the flipping plate 32 through a floating hole 44 and a spring 45. The outer end of the floating rod 46 is fixedly connected to the cam 42. The spring 45 is arranged between the inner end of the floating rod 46 and the inner end of the floating hole 44. Blocking blocks 47 are arranged on the outer sides of the upper and lower ends of the transmission groove 41.

[0043] Further, the driving structure 4 further includes an inner groove 48 arranged inside the flipping plate 32. The inner groove 48 communicates with the floating hole 44 through a through hole 49. A baffle 410 is floatingly installed in the inner groove 48. A connecting rod 411 is slidably installed in the through hole 49. The two ends of the connecting rod 411 are respectively fixedly connected to the baffle 410 and the floating rod 46.

[0044] In this embodiment of the present application, due to the adoption of the above structure, when it is necessary to control the sliding pressure plate 33 to move forward / backward, an inner hexagon wrench is inserted into the hexagonal groove 43 and pressed. The floating rod 46 moves towards the inner end of the floating hole 44, and the spring 45 is compressed and shortened. The baffle 410 disengages from the contact with the inner end of the inner groove 48. At the same time, both sides of the cam 42 disengage from a pair of blocking blocks 47. Then, the inner hexagon wrench is rotated to make the cam 42 rotate 180° around the axis of the floating rod 46. The distal end 421 of the cam 42 faces away from / towards the bent end 331, and the front / rear side walls of the transmission groove 41 are pushed. After the movement of the sliding pressure plate 33 is completed, the inner hexagon wrench is disengaged from the hexagonal groove 43. The spring 45 releases elastic potential energy to push the floating rod 46 to slide outwards from the floating groove. Both sides of the cam 42 come into contact with a pair of blocking blocks 47 again, and the baffle 410 comes into contact with the inner end of the inner groove 48. In this way, the cam 42 is restricted by a pair of blocking blocks 47 and cannot rotate, so as to ensure that the sliding pressure plate 33 cannot move again after sliding forward / backward, ensuring the firm installation of the tool 13.

[0045] Embodiment 4:

[0046] As Figures 3 to 6 shown, in this embodiment, in addition to including the structural features of the foregoing embodiments, the locking structure 5 includes a pair of clamping grooves 51 respectively arranged at the top and bottom ends of the flipping groove 31, a vertical groove 52 penetrating the flipping plate 32 up and down, a pair of connecting grooves 53 arranged on the front side of the flipping plate 32 and communicating with the vertical groove 52, and a plug rod 55 that is floatingly installed in the vertical groove 52. A tension spring 54 is arranged between the outer end that can be inserted into the corresponding clamping groove 51 and the inner end. A linkage structure 6 is installed in each connecting groove 53. The linkage structure 6 is used to control the corresponding plug rod 55 to be inserted into the clamping groove 51 when the inner wall of the bent end 331 approaches the front side of the flipping plate 32.

[0047] Further, the linkage structure 6 includes a fixed block 61 fixedly installed on the inner side wall of the bent end 331, an installation groove 62 penetrating the insertion rod 55 from left to right, and a floating block 63 floatingly installed in the installation groove 62 and the connection groove 53. A connecting rod 64 is hinged to the inner side wall of the floating block 63, and the other end of the connecting rod 64 is hinged to the side wall of the installation groove 62 close to the corresponding clamping groove 51.

[0048] In this embodiment of the present application, due to the above structure, when the bent end 331 approaches the front end of the turning plate 32, each fixed block 61 enters the connection groove 53, pushes each floating block 63 into the installation groove 62, and then drives each connecting rod 64 to push each insertion rod 55 to slide outwards. When the inner side wall of the bent end 331 abuts against the front end of the turning plate 32, the inner end of each installation groove 62 abuts against the inward side wall of the corresponding fixed block 61, and the outer ends of each insertion rod 55 also insert into the corresponding clamping groove 51, and the tension spring 54 between a pair of insertion rods 55 elongates and deforms to store elastic potential energy;

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

[0050] It should be noted that in this article, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including that element.
