Description

Technical Field

[0001] This invention relates to the field of planar milling machines, and more particularly to a CNC planar milling machine for machining optical crystals. Background Technology

[0002] In the field of optical crystal processing, CNC planar milling machines are the core equipment for achieving precision cutting of crystal planes. However, their processing accuracy is highly susceptible to factors such as tool stability, edge cutting control, and monitoring reliability. Traditional CNC planar milling machines have significant drawbacks: after the milling cutter is installed, it relies solely on the tail clamping for fixation. When the milling cutter extension length is adjusted to accommodate irregularly shaped crystals or inclined surfaces, the clamping point is relatively far back, resulting in a lack of effective support for the milling cutter shank. This leads to vibration during high-speed rotation, causing edge chipping and breakage of the optical crystal, severely impacting the processing yield. Simultaneously, the lack of real-time monitoring of the distance between the milling cutter and the crystal edge during processing means that processing parameters cannot be adjusted promptly when edge cutting stress changes abruptly, further exacerbating defects. Furthermore, residual coolant and foam on the crystal surface interfere with detection accuracy, and problems such as clamping misalignment and positional misalignment are difficult to detect in real time, easily leading to ineffective processing. This restricts the accuracy and efficiency of optical crystal processing, failing to meet the production requirements of high-precision optical devices. To address these technical pain points, this invention proposes a CNC planar milling machine for processing optical crystals to overcome the shortcomings of traditional equipment and improve the processing accuracy and yield of optical crystals. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a CNC planar milling machine for processing optical crystals.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a CNC planar milling machine for processing optical crystals, comprising a base, a body mounted on the top rear side of the base, a top compartment mounted on the top of the body, a geared motor mounted inside the top compartment, a drive compartment mounted on the front drive end of the geared motor, a display screen mounted on the front of the drive compartment, a servo motor mounted on the top of the drive compartment, a working shaft fixedly connected to the bottom drive end of the servo motor, a fixed head mounted on the bottom of the working shaft, a locking screw head rotatably connected to the lower part of the fixed head, uniformly distributed telescopic tubes fixedly connected to the outer periphery of the fixed head, infrared monitoring probes fixedly connected to the bottom telescopic ends of the telescopic tubes, a limit tube slidably connected to the bottom of the working shaft, a fixed rod fixedly connected to one side of the lower part of each telescopic tube, the end of the fixed rod away from the telescopic tube fixedly connected to the lower part of the outer periphery of the limit tube, a milling cutter provided inside the limit tube, and limit grooves formed in the middle of both sides of the outer periphery of the limit tube. The milling cutter is slidably connected. A pump body and a liquid storage tank are installed inside the fixed head. The pump body's input end is connected to the liquid storage tank, and its output end is connected to the top of the telescopic tube. A gear ring is fixedly connected to the lower inner part of the locking head. Driven gears are meshed on both sides of the gear ring. A rotating rod is fixedly connected to the middle of each driven gear. A driving bevel gear is fixedly connected to the lower outer circumference of each rotating rod. A driven bevel gear is meshed on one side of the lower part of each driving bevel gear. A threaded rod is fixedly connected to the middle of each driven bevel gear. One end of the threaded rod is mounted inside the locking head via a rotating seat. A clamping block is threadedly connected to the end of the threaded rod away from the driven bevel gear. The clamping blocks are slidably connected to the inner side of the limiting groove. A limiting block is slidably connected to the upper inner side of each clamping block. The top of each limiting block is fixedly connected to the bottom of the fixed head. The top of each rotating rod is rotatably connected to the bottom of the limiting block. The driven gear, driving bevel gear, clamping block, and limiting block are all located inside the locking head.

[0005] Preferably, the front of the machine body has a cavity, and a lifting seat is slidably connected to the inner side of the cavity. Multiple straight pipes are installed on the upper and lower sides of the middle of the lifting seat, and the middle of each straight pipe is set as a corrugated section.

[0006] Preferably, an industrial camera is installed in the middle of the front side of the lifting seat, and the industrial camera is electrically connected to the display screen. Air outlets are provided at the upper and lower parts of the front side of the lifting seat, and the air outlets are connected to the inside of the straight pipe.

[0007] Preferably, both sides of the lifting seat are threaded with lead screws, which are installed inside the cavity. The end of the straight tube away from the lifting seat is fixedly connected to the upper and lower parts of the cavity.

[0008] Preferably, an electric worktable is installed on the front top of the base, and the top of the electric worktable has evenly distributed mounting holes and mounting slots. The electric worktable is used to install optical crystal processing fixtures.

[0009] Preferably, a control display panel is installed on one side of the machine body, which is used to control other driving devices and display their working status.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This invention achieves precise adjustment of the milling cutter's mounting and extension length through a locking screw head, gear ring, bevel gear transmission, and clamping block structure, which can flexibly adapt to the processing requirements of irregularly shaped optical crystals and inclined surfaces. At the same time, with the linkage design of the pump body, liquid storage tank, and telescopic tube inside the fixed head, after the milling cutter extension is adjusted, the telescopic tube can synchronously drive the limiting tube to slide through the fixed rod, realizing full-stroke wrapping support for the milling cutter shank. This solves the problem of unstable rotation caused by the clamping and fixing point being too far back after the milling cutter extends in traditional milling machines, significantly improving the stability of the milling process and reducing the risk of edge chipping and breakage caused by tool vibration from the root.

[0012] 2. The present invention has an infrared monitoring probe at the bottom of the telescopic tube evenly distributed around the outer periphery of the fixed head. It can monitor the distance between the milling cutter and the optical crystal and the position of the crystal edge in real time. When the milling cutter is detected to be close to the crystal edge, the system automatically controls the servo motor to reduce the speed and raises the cutting edge through the hydraulic rod. This achieves dynamic adaptation of edge processing parameters, effectively avoiding edge chipping caused by sudden changes in edge cutting stress in traditional processing, greatly improving the processing qualification rate and accurately avoiding edge processing defects.

[0013] 3. This invention uses a lead screw to drive a lifting platform, which in turn moves an industrial camera up and down. This allows for full-process visual monitoring of the clamping status before optical crystal processing and the milling process during processing. Real-time feedback is provided through a display screen, enabling operators to quickly identify problems such as clamping misalignment or misalignment, thus avoiding ineffective processing. Simultaneously, as the lifting platform moves, it stretches or compresses a straight tube with corrugated sections, using the air outlet to achieve a cyclic action of air suction and spray. This efficiently removes coolant and foam from the crystal surface, preventing them from interfering with the spacing detection accuracy of the infrared monitoring probe. This ensures the accuracy of edge recognition and parameter adjustment, further guaranteeing anti-chipping effects and ensuring processing accuracy and monitoring reliability.

[0021] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] like Figures 1-6The CNC planar milling machine for processing optical crystals shown includes a base 101, a body 104 mounted on the rear top of the base 101, a top chamber 105 mounted on the top of the body 104, a geared motor installed inside the top chamber 105, a drive chamber 130 mounted on the front drive end of the geared motor, a servo motor mounted on the top of the drive chamber 130, a work shaft 107 fixedly connected to the bottom drive end of the servo motor, a fixed head 117 mounted on the bottom of the work shaft 107, a locking head 122 rotatably connected to the lower part of the fixed head 117, a gear ring 123 fixedly connected to the lower inner side of the locking head 122, driven gears 125 meshing on both sides of the gear ring 123, rotating rods 128 fixedly connected to the middle of each driven gear 125, and rotating rods 128 fixedly connected to the lower outer periphery of each rotating rod 128. A drive bevel gear 129 is connected to the lock head 122. A driven bevel gear 127 is meshed with one side of the lower part of the drive bevel gear 129. A threaded rod 126 is fixedly connected to the middle of the driven bevel gear 127. One end of the outer circumference of the threaded rod 126 is mounted on the inner side of the lock head 122 through a rotating seat. A clamping block 118 is threadedly connected to the end of the threaded rod 126 away from the driven bevel gear 127. The clamping block 118 is slidably connected to the inner side of the limiting groove 119. A limiting block 124 is slidably connected to the upper inner side of the clamping block 118. The top of the limiting block 124 is fixedly connected to the bottom of the fixed head 117. The top of the rotating rod 128 is rotatably connected to the bottom of the limiting block 124. The driven gear 125, the drive bevel gear 129, the clamping block 118 and the limiting block 124 are all located inside the lock head 122.

[0023] Furthermore, in specific implementation, people can select a suitable milling cutter 110 according to the processing requirements, insert the shank of the milling cutter 110 into the limiting tube 121, adjust it to a suitable position, and then rotate the locking head 122. The locking head 122 can drive the driven gear 125 meshing with it to rotate through the gear ring 123. The driven gear 125 can drive the driving bevel gear 129 coaxial with it to rotate. The driving bevel gear 129 can drive the driven bevel gear 127 meshing with it to rotate synchronously. The driven bevel gear 127 can drive the fixed threaded rod 126 to rotate synchronously. The threaded rod 126 can drive the clamping block 118 to move. The clamping blocks 118 on both sides can clamp and fasten the shank of the milling cutter 110, completing the installation of the milling cutter 110. In specific work, through the drive chamber 13 The servo motor on the 0 can drive the working shaft 107 to rotate, which in turn drives the milling cutter 110 mounted at the bottom to rotate. The high-speed rotating milling cutter 110 can fully mill the optical crystal. When milling irregularly shaped optical crystals, the milling cutter 110 can be loosened by locking the screw head 122, and then the milling cutter 110 can be extended downwards, allowing for adjustment of the extension length of the milling cutter 110 for convenient use. Furthermore, the geared motor inside the top chamber 105 can drive the drive chamber 130 to deflect, enabling the processing of inclined surfaces. Furthermore, the hydraulic rod installed inside the machine body 104 can adjust the height of the top chamber 105, thereby enabling further auxiliary milling work and facilitating the processing of optical crystals with different processing requirements.

[0024] Among them, an electric worktable 102 is installed on the top front side of the base 101. The top of the electric worktable 102 is provided with evenly distributed mounting holes and mounting slots. The electric worktable 102 is used to install optical crystal processing fixtures, specifically electric vacuum chucks. A control display panel 103 is installed on one side of the body 104. The control display panel 103 is used to control other driving devices and display the working status.

[0025] Furthermore, in practical implementation, people can perform milling work on optical crystals using a planar milling machine. In specific use, people can install an electric vacuum chuck onto the electric worktable 102 using fixing bolts. The electric vacuum chuck can be used to adsorb and fix the optical crystal. During milling, the electric slide at the bottom of the electric worktable 102 can be used to slide and translate the electric worktable 102, thereby moving the optical crystal and facilitating subsequent milling work.

[0026] The fixed head 117 is fixedly connected to a uniformly distributed telescopic tube 108 on its outer periphery. An infrared monitoring probe 109 is fixedly connected to the telescopic end of the bottom of each telescopic tube 108. A limit tube 121 is slidably connected to the bottom of the working shaft 107. A fixed rod 120 is fixedly connected to one side of the lower part of each telescopic tube 108. The end of the fixed rod 120 away from the telescopic tube 108 is fixedly connected to the lower part of the outer periphery of the limit tube 121. A milling cutter 110 is provided inside the limit tube 121. Limit grooves 119 are opened in the middle of both sides of the outer periphery of the limit tube 121. The limit tube 121 is slidably connected to the milling cutter 110. A pump body and a liquid storage tank are installed inside the fixed head 117. The pump body input end is connected to the liquid storage tank, and the pump body output end is connected to the top of the telescopic tube 108.

[0027] Furthermore, in practical implementation, the pump body inside the fixed head 117 can draw liquid from the storage tank and pump it into the telescopic tube 108, allowing the telescopic tube 108 to extend synchronously. The telescopic tube 108, through which the fixed rod 120 drives the limiting tube 121 to slide, ensures that the limiting tube 121 fully encloses the shank of the milling cutter 110. This ensures that the milling cutter 110 remains effectively supported and limited after extension, preventing the clamping point from shifting backward after extension and affecting the smooth rotation of the milling cutter 110. During actual milling operations, the extension... The infrared monitoring probe 109 at the bottom of the tube 108 can monitor the optical crystal at the bottom and control the distance between the optical crystals. The infrared monitoring probe 109 can help determine the relative position of the milling cutter 110 and the edge of the optical crystal during the actual milling process. In actual use, when the infrared monitoring probe 109 detects the edge of the optical crystal through spacing monitoring, the servo motor and hydraulic rod will start to work, so that the milling cutter 110 will reduce its speed and raise its cutting edge when it approaches the edge of the optical crystal, thereby avoiding the occurrence of chipping or breakage of the optical crystal, which is beneficial to the actual milling work.

[0028] The machine body 104 has a cavity 111 at the front, and a lifting seat 114 is slidably connected to the inside of the cavity 111. Multiple straight pipes 115 are installed on the upper and lower sides of the middle of the lifting seat 114. The middle of each straight pipe 115 is corrugated. An industrial camera 113 is installed on the middle of the front side of the lifting seat 114. An air outlet 116 is opened on the upper and lower sides of the front side of the lifting seat 114. The air outlet 116 is connected to the inside of the straight pipe 115. A lead screw 112 is threaded through and connected to the middle of both sides of the lifting seat 114. The lead screw 112 is installed inside the cavity 111. The end of the straight pipe 115 away from the lifting seat 114 is fixedly connected to the upper and lower parts inside the cavity 111. A display screen 106 is installed at the front of the drive chamber 130.

[0029] Furthermore, in specific implementation, the operation of the lead screw 112 drives the lifting seat 114 to move inside the cavity 111. The industrial camera 113 at the front of the lifting seat 114 can monitor the optical crystal fixed on the front side and display the optical crystal on the display screen 106. The display screen 106 helps people observe the state of the optical crystal before and during processing, avoiding the optical crystal from being misaligned during adsorption and fixation, which could cause problems in subsequent processing and avoid the need for people to bend over and squat down to check. At the same time, it can help people observe the milling process of the optical crystal in real time during processing, so that when the milling cutter 110 and the optical crystal are misaligned, it can be detected immediately. People can detect and avoid operational errors immediately. When a chipping occurs, it can be detected immediately, avoiding unnecessary processing and wasting time. This is beneficial to actual processing work. In actual use, people can move the lifting seat 114 within the monitoring range. When the lifting seat 114 moves, it will compress or stretch the upper and lower straight tubes 115. When stretched, external air will enter the straight tube 115 through the air outlet 116. When compressed, the gas inside the straight tube 115 will be ejected again through the air outlet 116, which will impact the coolant and foam on the front optical crystal. This will prevent the coolant and foam from affecting the spacing monitoring work of the infrared monitoring probe 109, which is beneficial to actual use.

[0030] Working principle:

[0031] In practical use, a surface milling machine can be used to mill the optical crystal. Specifically, an electric vacuum chuck can be mounted on an electric worktable 102 using fixing bolts. The electric vacuum chuck can be used to adhere and fix the optical crystal. During milling, the electric slide at the bottom of the electric worktable 102 can slide and translate the worktable 102, allowing the optical crystal to move and facilitating subsequent milling operations. Afterward, a suitable milling cutter 110 can be selected according to the processing requirements, and the shank of the milling cutter 110 is inserted into the limiting tube 121. After adjusting to the appropriate position, the locking head 122 is rotated. The locking head 122 can drive the driven gear meshing with it via the gear ring 123. The driven gear 125 rotates, which in turn drives the coaxial driving bevel gear 129 to rotate. The driving bevel gear 129 then drives the meshing driven bevel gear 127 to rotate synchronously. The driven bevel gear 127 then drives the fixed threaded rod 126 to rotate synchronously. The threaded rod 126 then moves the clamping block 118. The clamping blocks 118 on both sides clamp and secure the shank of the milling cutter 110, completing the installation of the milling cutter 110. In actual operation, the servo motor on the drive chamber 130 drives the working shaft 107 to rotate. The working shaft 107 then drives the bottom-mounted milling cutter 110 to rotate. The high-speed rotation of the milling cutter 110 enables the milling of optical crystals... For milling irregularly shaped optical crystals, the milling cutter 110 can be loosened by locking the rotating head 122, allowing it to extend downwards and adjust its length. Furthermore, the geared motor inside the top chamber 105 drives the drive chamber 130 to deflect, enabling the machining of inclined surfaces. The hydraulic rod inside the machine body 104 allows for height adjustment of the top chamber 105, further assisting in milling and facilitating the processing of optical crystals with different processing requirements. In actual use, the pump inside the fixed head 117 draws liquid from the storage tank and... The pump is inserted into the telescopic tube 108, allowing the telescopic tube 108 to extend synchronously. Through the telescopic tube 108, the fixed rod 120 drives the limiting tube 121 to slide, enabling the limiting tube 121 to fully enclose the end mill 110 rod. This ensures that the end mill 110 remains effectively supported and limited after extension, preventing the clamping point from shifting backward and affecting the smoothness of the end mill 110's rotation. During actual milling, the infrared monitoring probe 109 at the bottom of the telescopic tube 108 monitors the optical crystal at the bottom, controlling the distance between the optical crystals. The infrared monitoring probe 109 helps determine the relative position of the end mill 110 and the edge of the optical crystal during milling. In practical use…When the infrared monitoring probe 109 detects the edge of the optical crystal through spacing monitoring, the servo motor and hydraulic rod start working, causing the milling cutter 110 to reduce its speed and raise its cutting edge when approaching the edge of the optical crystal. This prevents the optical crystal from chipping or breaking, which is beneficial for actual milling work. In actual operation, the lead screw 112 drives the lifting seat 114 to move inside the cavity 111. The industrial camera 113 at the front of the lifting seat 114 can monitor the optical crystal fixed in front and display it on the display screen 106. The display screen 106 helps people observe the state of the optical crystal before and during processing, avoiding the optical crystal from being skewed during adsorption and fixation, which could cause problems in subsequent processing and avoid the need for people to bend over and squat down to check. During processing, this system allows for immediate observation of the milling process on the optical crystal. It enables immediate detection of misalignment between the milling cutter 110 and the optical crystal, preventing operational errors. It also allows for immediate detection of chipping, avoiding wasted time and unnecessary processing. In practical use, the lifting platform 114 can be moved within the monitoring range. During movement, the lifting platform 114 compresses or stretches the upper and lower straight tubes 115. During stretching, external air enters the straight tube 115 through the air outlet 116. During compression, the gas inside the straight tube 115 is ejected again through the air outlet 116, impacting the coolant and foam on the front optical crystal. This prevents the coolant and foam from affecting the spacing monitoring of the infrared monitoring probe 109, thus improving practical application.
