Description

Technical Field

[0001] This application relates to the field of prism cutting equipment technology, and in particular to a prism cutting device. Background Technology

[0002] A prism is an optical element, typically made of a transparent material (such as glass or plastic), with at least two planar surfaces. It is usually polygonal in shape. The main function of a prism is to refract light, that is, to change the direction of light propagation. When light passes through a prism, due to the difference in refractive index between different wavelengths of light, the prism can decompose white light into different colors of the spectrum (such as the colors of a rainbow). This is the phenomenon of light dispersion. Prisms come in various shapes and types, the most common being triangular prisms, square prisms, and hexagonal prisms. Prisms are widely used in optical instruments, laser technology, photography, microscopes, and other fields.

[0003] When cutting a prism, a large amount of frictional heat is generated, which causes the local temperature at the cutting point to rise sharply. In addition, a large amount of material debris (powder) is also generated. Therefore, cutting fluid needs to be sprayed on the prism when cutting it. However, in the existing technology, most of the fixed nozzles are used, which can easily cause uneven temperature distribution in the cutting area, resulting in local thermal stress concentration in the prism and causing microcracks to form on or inside the prism. Utility Model Content

[0004] To improve the problem of nozzle fixation in cutting fluid, this application provides a prism cutting device.

[0005] The prism cutting device provided in this application adopts the following technical solution:

[0006] A prism cutting device includes a base, a water collection tank fixedly mounted on the top surface of the base, a worktable fixedly mounted on one side of the water collection tank, a clamping mechanism adjustable according to the size of the prism mounted on the top surface of the base, a clamping block for clamping the prism fixedly mounted on the movable end of the clamping mechanism, and an auxiliary mechanism for reciprocatingly spraying cutting fluid onto the prism mounted on the top surface of the base, a spray pipe for spraying cutting fluid onto the prism fixedly mounted on the movable end of the auxiliary mechanism.

[0007] By adopting the above technical solution, the base is the basic support structure of the entire device. Its core function is to provide installation benchmarks and stable mechanical support for the water collection tank, worktable, clamping mechanism, and auxiliary mechanisms, ensuring the equipment is stable and reliable during operation and avoiding the impact of vibration on cutting accuracy. The water collection tank is used to collect used cutting fluid, realizing the recycling of cutting fluid. The worktable provides a flat and horizontal operating plane for placing and cutting prisms, ensuring that the prisms are in the correct position during clamping and processing, which is the basis for achieving precise cutting. The clamping block is the actuator that directly contacts the prism. It is made of rubber with good elastic deformation ability and a high coefficient of friction, which can effectively clamp the workpiece and prevent hard scratches or indentations on the smooth or precision surface of the prism. Its clamping surface is designed with a serrated shape, which further increases the friction force and prevents the prism from sliding or twisting when under cutting force, ensuring the stability of the processing. The clamping mechanism is one of the core functional modules of the entire device. Its core function is to drive the movement of the clamping block to adapt to and fix prisms of different sizes. The auxiliary mechanism is used to drive the nozzle to reciprocate to spray cutting fluid onto the prism. The nozzle is used to spray cutting fluid onto the prism.

[0008] Preferably, the clamping mechanism includes a rotating plate rotatably connected to the clamping block, a support frame is fixedly provided on the top surface of the base, a bevel gear set is provided inside the support frame, and a connecting device is provided on one side of the bevel gear set.

[0009] By adopting the above technical solution, the rotating plate is a key transmission component in the clamping mechanism. It is rotatably connected to both the clamping block and the moving plate. Its core function is to allow the clamping block to deflect at an angle during the advancement of the moving plate, thereby adaptively conforming to the sides of prisms of different shapes (such as wedges and irregular shapes), achieving uniform force clamping, and avoiding stress concentration that could damage brittle optical components. The support frame is an important structure and protective cover, providing accurate installation positions for precision transmission components such as the bevel gear set and the reciprocating lead screw. The core function of the bevel gear set is to change the direction of power transmission.

[0010] Preferably, the connecting device includes a reciprocating lead screw rotatably disposed inside the support frame, the reciprocating lead screw being fixedly disposed on one side of the bevel gear set, a connecting plate slidably disposed inside the support frame symmetrically disposed on the outer surface of the reciprocating lead screw, and a movable plate being fixedly disposed on one side of the connecting plate.

[0011] By adopting the above technical solution, the reciprocating lead screw is used to convert the rotational motion transmitted from the bevel gear set into the linear reciprocating motion of the connecting plate. The connecting plate is a component that directly cooperates with the reciprocating lead screw. Its function is to convert the rotational motion of the reciprocating lead screw into its own precise linear motion. The moving plate is fixedly connected to the connecting plate. Its function is to transmit the linear motion of the connecting plate and to serve as the mounting base for the rotating plate.

[0012] Preferably, a protective frame one is fixedly installed on one side of the support frame, a protective frame two is fixedly installed on the top of the protective frame one, a motor is fixedly installed inside the protective frame two, and a bevel gear set two rotatably connected to the output shaft of the motor is fixedly installed inside the protective frame one.

[0013] By adopting the above technical solution, the function of protective frame one and protective frame two is to provide a sealed protective space for the motor and the bevel gear set two on its output shaft. They can effectively prevent foreign objects such as cutting fluid, metal chips, and dust from entering the motor and gear meshing area, avoiding faults such as short circuits, jamming, or accelerated wear, and significantly improving the service life and reliability of the core drive components. The motor is the single power source and motion control core of the entire device, and the function of bevel gear set two is to transmit and distribute power.

[0014] Preferably, a connecting post two is fixedly provided on one side of the bevel gear set two, a connecting post one is fixedly provided on one side of the connecting post two, a pawl is fixedly provided on one side of the connecting post one, and a ratchet that meshes with the pawl is fixedly provided on one side of the bevel gear set one.

[0015] By adopting the above technical solution, connecting column 2 and connecting column 1 are used to transmit the driving force of the motor to the pawl. The pawl and ratchet together constitute a typical one-way clutch or one-way transmission mechanism. Its core function is to achieve selective transmission of power. Specifically, it only transmits the torque of the motor in counterclockwise direction to the ratchet and bevel gear set 1, thereby driving the clamping mechanism to move. When the motor rotates clockwise, the pawl will slide on the back of the ratchet teeth and "free-spin" occurs. The power is cut off here and cannot be transmitted to the clamping mechanism.

[0016] Preferably, the auxiliary mechanism includes a connecting frame fixedly connected to one side of the support frame, a rotating shaft rotatably connected inside the connecting frame is fixedly provided on one side of the second bevel gear set, and a driving device is provided on one side of the rotating shaft.

[0017] By adopting the above technical solution, the connecting frame provides mounting supports and movement space for swinging components such as the rotating shaft, rotating arc plate, and arc plate one, while restricting these components to move only within the designed plane, ensuring the accuracy and reliability of their movement trajectory. The rotating shaft is the transmission shaft that transmits power from the bevel gear set two to the auxiliary mechanism, and its function is to reliably transmit rotational motion and torque between the two components.

[0018] Preferably, the driving device includes a rotating arc plate fixedly disposed with a rotating shaft, a connecting rod fixedly disposed with a nozzle is rotatably connected inside the connecting frame, an arc plate is fixedly disposed on one side of the connecting rod, and an auxiliary cylinder slidably connected inside the arc plate is fixedly connected to one side of the rotating arc plate.

[0019] By adopting the above technical solution, the rotating arc plate and the auxiliary cylinder fixed on it together constitute the "crank" part of a crank-slider mechanism. Its function is to convert the continuous rotational motion transmitted from the rotating shaft into the planar circular motion of the auxiliary cylinder. The arc plate is used to convert the circular motion of the auxiliary cylinder into the reciprocating swing motion of itself (and the connecting rod fixed to it). The connecting rod is the final output component of the auxiliary mechanism. Its function is to transmit the swing motion of the arc plate to the nozzle, driving the nozzle to perform synchronous reciprocating swing.

[0020] Preferably, the clamping block is made of rubber, and the clamping surface of the clamping block is serrated.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By using a bevel gear set two to drive the rotating arc plate, the nozzle reciprocates to spray cutting fluid on the upper part of the prism, which solves the problem of uneven cooling caused by traditional fixed nozzles. The design of the auxiliary cylinder and the arc plate one allows the coolant coverage to be dynamically adjusted with the cutting path, avoiding material chipping caused by local overheating. It is especially suitable for processing large-size or irregularly shaped prisms.

[0023] 2. By using the reciprocating lead screw, the clamping blocks can automatically adjust the clamping force and contact area according to the shape of the prism. Compared with traditional manual adjustment or fixed clamps, this design reduces manual intervention, adapts to the processing needs of complex prisms such as ultra-thin and curved surfaces, and avoids workpiece deformation caused by uneven clamping force. The clamping blocks are made of rubber with serrated clamping surfaces, which significantly improves friction, prevents the prism from sliding during cutting, and absorbs the vibration generated during cutting, reducing errors or damage to the prism caused by vibration and improving the flatness of the cut surface.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] This application discloses a prism cutting device.

[0036] Reference Figure 1 A prism cutting device includes a base 1, the top surface of which is fixedly connected to a water collection tank 2. The water collection tank 2 is hollow and has an openable sealing door. One side of the water collection tank 2 is fixedly connected to a workbench 3. The workbench 3 is hollow and communicates with the water collection tank 2. The top surface of the workbench 3 has several circular holes for draining cutting fluid into the water collection tank 2. The top surface of the base 1 is provided with a clamping mechanism 5, which is adjustable according to the size of the prism. The movable end of the clamping mechanism 5 is fixedly connected to a clamping block 4 for clamping the prism. The clamping block 4 is made of rubber. The clamping surface is serrated, which can significantly improve friction, prevent the prism from sliding during the cutting process, and absorb the vibration generated during the cutting process, reduce the error or damage to the prism caused by vibration, and improve the flatness of the cutting surface. An auxiliary mechanism 6 is provided on the top surface of the base 1. The auxiliary mechanism 6 is used to reciprocate spray cutting fluid onto the prism. The movable end of the auxiliary mechanism 6 is fixedly connected to the spray pipe 7. The spray pipe 7 is used to spray cutting fluid onto the prism. Several nozzles are opened on the side of the spray pipe 7 near the worktable 3. The spray pipe 7 can be connected to an external device for automatically injecting cutting fluid. The spray pipe 7 is located above the worktable 3 and will not affect the cutting of the prism.

[0037] In use, the prism to be cut is placed on the top surface of the workbench 3, and the distance between the clamping blocks 4 is adjusted by the clamping mechanism 5 to clamp the prism. Cutting fluid is sprayed onto the prism on the top surface of the workbench 3 through the spray pipe 7. While spraying the cutting fluid, the auxiliary mechanism 6 makes the spray pipe 7 swing back and forth to ensure uniform cooling. The sprayed cutting fluid can flow into the water collection tank 2 through the round hole opened on the top surface of the workbench 3 for recycling.

[0038] Reference Figures 2-4 The clamping mechanism 5 includes a movable plate 51 fixedly connected to the top surface of the base 1. The inner wall of the support frame 53 is rotatably connected to the bevel gear set 54. A connecting device is provided on one side of the bevel gear set 54. The connecting device includes a reciprocating screw 55 rotatably connected to the inner wall of the support frame 53. The reciprocating screw 55 is fixedly connected to the inside of one side of the bevel gear set 54. A limiting plate is fixedly provided on the side of the reciprocating screw 55 near the bevel gear set 54 to protect the bevel gear set 54 and prevent it from being disturbed by the outside. The outer surface of the reciprocating screw 55 is slidably connected to two connecting plates 510. The two connecting plates 510 are symmetrically arranged and slidably connected to the inner wall of the support frame 53. One side of the connecting plate 510 is fixedly connected to the movable plate 51. The movable plate 51 is located on the side away from the reciprocating screw 55. The opposite surfaces of the two movable plates 51 are rotatably connected to two rotating plates 52. The two rotating plates 52 are symmetrically arranged, and the clamping block 4 is slidably connected to the opposite surfaces of the two rotating plates 52.

[0039] In use, the rotation of the bevel gear set 54 drives the reciprocating screw 55, which is fixedly connected to the bevel gear set 54, to rotate. The rotation of the reciprocating screw 55 causes the two connecting plates 510, which are slidably connected to the reciprocating screw 55, to slide inside the support frame 53, thereby causing the moving plate 51 to slide. The moving plate 51 is located on the top surface of the worktable 3. The two connecting plates 510 move towards each other, causing the rotating plate 52 and the clamping block 4 to move towards each other, thereby clamping the prism placed on the top surface of the worktable 3.

[0040] Reference Figures 2-4 The top surface of the support frame 53 is fixedly connected to the first protective frame 511. The top of the first protective frame 511 is fixedly connected to the second protective frame 513. The second protective frame 513 has ventilation holes. The inner wall of the second protective frame 513 is fixedly connected to the outer casing of the motor 514. The output shaft of the motor 514 is fixedly connected to the center of the second bevel gear set 512, and the second bevel gear set 512 is rotatably connected inside the first protective frame 511. The center of one side of the second bevel gear set 512 is fixedly connected to the center of the second connecting post 59. The second connecting post 59 is located on the side away from the motor 514. The center of one side of 9 is fixedly connected to the center of the connecting post 58. The connecting post 58 is located on the side away from the bevel gear set 512. The center of one side of the connecting post 58 is fixedly connected to the center of the pawl 57. The pawl 57 is located on the side away from the connecting post 59. The center of one side of the bevel gear set 54 is fixedly connected to the ratchet 56. The ratchet 56 is located on the side away from the reciprocating screw 55. The ratchet 56 and the pawl 57 are meshed and matched. The pawl 57 cannot drive the ratchet 56 to rotate when rotated clockwise. On the contrary, the ratchet 56 can drive the ratchet 56 to rotate when rotated counterclockwise.

[0041] In use, the motor 514 drives the bevel gear set 2 512 to rotate counterclockwise, which in turn drives the connecting column 2 59, which is fixedly connected to the bevel gear set 2 512, to rotate counterclockwise. This in turn drives the connecting column 1 58 and the pawl 57 to rotate counterclockwise, which in turn drives the ratchet 56 to rotate, thereby driving the moving plate 51, the rotating plate 52, and the clamping block 4 to clamp the prism.

[0042] Reference Figure 2 , Figure 5 The auxiliary mechanism 6 includes a connecting frame 61 fixedly connected to one side of the support frame 53. The connecting frame 61 is located on the side closer to the worktable 3. One side of the bevel gear set 512 is fixedly connected to the rotating shaft 62. The rotating shaft 62 is located on the side away from the connecting column 59, and the rotating shaft 62 is rotatably connected inside the connecting frame 61. A driving device is provided on one side of the rotating shaft 62. The driving device includes a rotating arc plate 63 fixedly connected to one side of the rotating shaft 62. The rotating arc plate 63 is located on the side away from the bevel gear set 512. The inner wall of the connecting frame 61 is rotatably connected to the connecting rod 66. The connecting rod 66 is located on the side closer to the worktable 3, and the connecting rod 66 is fixedly connected to the nozzle 7. One side of the connecting rod 66 is fixedly connected to the arc plate 65. The arc plate 65 is located on the side away from the nozzle 7. One side of the rotating arc plate 63 is fixedly connected to the auxiliary cylinder 64, and the auxiliary cylinder 64 is slidably connected inside the arc plate 65.

[0043] In use, the rotation of the bevel gear set 512 drives the rotating shaft 62 to rotate, the rotation of the rotating shaft 62 drives the rotating arc plate 63 to rotate, and the rotation of the auxiliary cylinder 64 forms an eccentric rotation, which in turn drives the arc plate 65 to reciprocate. The movement of the arc plate 65 drives the connecting rod 66 and the nozzle 7, which are fixedly connected to the arc plate 65, to reciprocate in the horizontal direction.

[0044] The implementation principle of a prism cutting device according to an embodiment of this application is as follows:

[0045] In use, the prism to be cut is placed on the top surface of the workbench 3. The motor 514 drives the bevel gear set 2 512 to rotate counterclockwise, which in turn drives the connecting column 2 59, connecting column 1 58, and pawl 57 to rotate counterclockwise. This drives the ratchet 56 to rotate, which in turn drives the moving plate 51, rotating plate 52, and clamping block 4 to clamp the prism. Subsequently, the motor 514 drives the bevel gear set 2 512 to rotate clockwise. The rotation of the bevel gear set 2 512 drives the rotating shaft 62 to rotate, which in turn drives the rotating arc plate 63 to rotate. The rotation of the auxiliary cylinder 64 forms an eccentric rotation, which in turn drives the arc plate 1 65, connecting rod 66, and nozzle 7 to swing back and forth in the horizontal direction. The nozzle 7 sprays cutting fluid onto the prism on the top surface of the workbench 3. During the spraying of cutting fluid, uniform cooling is ensured. The sprayed cutting fluid can flow into the water collection tank 2 through the round hole on the top surface of the workbench 3 for recycling.

Various modifications and variations can be made to this application by those skilled in the art.
