Description

Technical Field

[0001] This invention belongs to the field of actuator cutting technology, and in particular relates to an actuator end cap cutting device. Background Technology

[0002] As a core component for controlling the opening and closing of valves and regulating fluid media, the operational stability of pneumatic actuators is closely related to the machining accuracy of their internal components. Among them, the end cap of the pneumatic actuator is a key sealing component, mainly used to seal the cavity opening of the actuator housing to prevent internal air pressure leakage or the intrusion of external impurities. To ensure that the end cap can be precisely fitted to the actuator housing, the end cap needs to be cut and machined with high precision.

[0003] Currently, laser cutting has become the main method for cutting pneumatic actuator end caps due to its advantages such as high cutting precision and smooth, burr-free cuts. However, in actual processing, to meet the requirements of pneumatic actuators for end cap strength, corrosion resistance, and lightweighting, end caps are often made of metal materials such as aluminum alloy and copper alloy. These materials generally have high reflectivity. When the laser beam emitted by the laser cutting head acts on the surface of the end cap, most of the laser energy is reflected by the material surface and cannot effectively act on the area to be cut to achieve efficient material removal. It is necessary to extend the laser action time or increase the laser power to complete the cutting, which significantly reduces the cutting efficiency. At the same time, if the reflected laser beam directly acts on the optical components of the laser cutting head (such as focusing lenses and protective lenses), it may also damage the components, shorten the service life of the equipment, and increase the frequency of maintenance.

[0004] To address this, an actuator cover cutting device is proposed. Summary of the Invention

[0013] Preferably, the rotary laser cutting mechanism includes a motor fixedly mounted on the lower surface of the mounting plate, a rotating plate fixedly mounted on the lower end of the motor's output shaft, and a laser cutting head fixedly mounted on the lower surface of the rotating plate.

[0014] Preferably, the light-reflecting absorption mechanism includes two elastic telescopic rods symmetrically fixed on the lower surface of the rotating plate. The lower ends of the two elastic telescopic rods are fixed with the same light-reflecting absorption ring. The inner sidewall of the light-reflecting absorption ring is provided with an annular reflective surface, and the inclination angle of the annular reflective surface is 45°.

[0015] Preferably, the elastic telescopic rod includes a sleeve fixedly disposed on the lower surface of the rotating plate, a movable rod slidably disposed at the lower end of the sleeve, the lower end of the movable rod being fixedly connected to the side wall of the light-absorbing ring, and a spring being fixedly disposed between the upper end of the movable rod and the inner wall of the sleeve.

[0016] Preferably, the smoking mechanism includes a smoking shell fixedly disposed on the upper surface of the rotating plate. The interior of the smoking shell is fixedly provided with a cooling plate, a suction fan, and a multi-stage filter screen from top to bottom. A smoking tube is fixedly disposed on the bottom side wall of the smoking shell. The light-absorbing ring adopts a hollow structure, and the inner annular reflective surface of the light-absorbing ring has multiple evenly distributed smoking holes. The end of the smoking tube away from the smoking shell is fixedly connected to the light-absorbing ring, and the smoking tube is connected to the light-absorbing ring.

[0017] Preferably, the heat dissipation mechanism includes an air outlet pipe fixedly disposed on the top of the side wall of the smoking shell, and a hollow air outlet plate fixedly disposed at the end of the air outlet pipe away from the smoking shell. The hollow air outlet plate is located below the cutting tray, and a plurality of evenly distributed air outlet holes are opened on the upper surface of the hollow air outlet plate.

[0018] Preferably, a first connecting rod is fixedly provided on one side of the hollow air outlet plate, and a slider is fixedly provided at the end of the first connecting rod away from the hollow air outlet plate. A groove that cooperates with the slider is opened on the circumferential wall of the cutting tray. A second connecting rod is fixedly provided on the side wall of the slider. An L-shaped sleeve extending downward is fixedly provided on one side of the rotating plate. The upper end of the second connecting rod is slidably connected to the lower end of the L-shaped sleeve.

[0019] Preferably, the upper surface of the cutting tray is provided with an annular heat dissipation groove, the bottom of the annular heat dissipation groove is fixedly embedded with an annular heat dissipation mesh, and the upper surface of the cutting tray and the periphery of the annular heat dissipation groove are provided with ventilation grooves.

[0020] Compared with existing technologies, the advantages of this invention are as follows:

[0021] 1. Through the design of the reflected light absorption mechanism, which, with the cooperation of the elastic telescopic rod and the reflected light absorption ring, can preferentially and closely fit the surface of the blank during the downward movement of the laser cutting head. Furthermore, the reflected light absorption ring, combined with the 45° inclined annular reflective surface, can completely cover the cutting area. When cutting blanks with high reflectivity, it can efficiently capture the reflected laser beam, preventing the reflected light from directly escaping or damaging the optical components of the laser cutting head. At the same time, it reduces the waste of effective cutting energy, significantly improves the laser energy utilization rate, and thus improves the cutting efficiency of blanks, ensuring a stable and reliable cutting process.

[0022] 2. Through the set smoke extraction mechanism, the smoke extraction mechanism utilizes the hollow structure of the reflective light absorption ring and multiple smoke extraction holes on the inner wall annular reflective surface. After the suction fan is started, a stable negative pressure can be formed inside the smoke extraction pipe and the reflective light absorption ring. Relying on the surrounding layout of the reflective light absorption ring around the cutting area, the smoke extraction holes can accurately target the core area of ​​the cutting path and quickly extract the metal smoke and dust generated during cutting. This effectively prevents the smoke from spreading to the surrounding environment or adhering to the surface of the optical components of the laser cutting head, ensuring a clear cutting field of view, avoiding smoke interference with the cutting process, and reducing the impact of pollutants on the working environment.

[0023] 3. Through the set heat dissipation mechanism, the heat dissipation mechanism uses the gas processed by the smoke extraction mechanism as the gas source. The gas is filtered through multiple layers of filters in the smoke extraction mechanism to remove impurities. After being cooled by the cooling plate, it is delivered to the hollow air outlet plate through the air outlet pipe. With the corresponding setting of the hollow air outlet plate and the annular heat dissipation groove of the cutting tray, as well as the air permeability of the annular heat dissipation mesh, the low temperature gas can be accurately blown to the bottom of the cutting part of the blank, quickly removing the heat accumulated during cutting. This effectively suppresses the softening and deformation of the cutting part due to high temperature. At the same time, the upward airflow and the negative pressure suction of the smoke extraction mechanism form a "downward push and upward suction" synergistic effect, further accelerating the smoke extraction efficiency.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] like Figures 1-6 As shown, an actuator cap cutting device includes a base 1, and further includes:

[0033] An L-shaped support plate 2 is fixedly mounted on one side of the top of the base 1. A cylinder 3 is fixedly mounted on the top of the L-shaped support plate 2. A mounting plate 4 is fixedly mounted on the moving end of the cylinder 3. A rotary laser cutting mechanism 5 is fixedly mounted on the lower surface of the mounting plate 4. The rotary laser cutting mechanism 5 includes a motor 51 fixedly mounted on the lower surface of the mounting plate 4. A rotating plate 52 is fixedly mounted on the lower end of the output shaft of the motor 51. A laser cutting head 53 is fixedly mounted on the lower surface of the rotating plate 52. The operation of the motor 51 drives the rotating plate 52 to rotate at a constant speed around its own axis. At the same time, the laser cutting head 53 also rotates. Simultaneously, the laser cutting head 53 starts and emits a high-energy laser beam. The beam is precisely focused on the blank cutting area inside the reflective light absorption ring 82 and begins to perform ring cutting on the blank. To avoid tangling of the wires, the motor 51 rotates 360° and then controls the rotation in the opposite direction.

[0034] A support column 6 is fixedly installed on the top of the base 1, and the support column 6 is positioned corresponding to the cylinder 3. A cutting tray 7 is fixedly installed on the upper end of the support column 6. A clamping fixture is pre-set on the upper surface edge of the cutting tray 7 to fix the blank. The clamping fixture adopts a conventional structure of screw and clamping plate (not shown in the figure). An annular heat dissipation groove 12 is opened on the upper surface of the cutting tray 7. An annular heat dissipation mesh 13 is fixedly embedded at the bottom of the annular heat dissipation groove 12. A ventilation groove 14 is opened on the upper surface of the cutting tray 7 and around the annular heat dissipation groove 12. When cold air is blown into the interior of the annular heat dissipation groove 12 through the annular heat dissipation mesh 13, it is blown outward through the ventilation groove 14, which can remove the heat from the bottom of the cutting part of the blank and prevent the bottom temperature of the cutting part of the blank from being too high.

[0035] A light-reflecting absorption mechanism 8 is located at the bottom of the rotary laser cutting mechanism 5, and is positioned corresponding to the laser head of the rotary laser cutting mechanism 5. It is used to absorb the laser beam reflected by the rotary laser cutting mechanism 5. The light-reflecting absorption mechanism 8 includes two elastic telescopic rods 81 symmetrically fixed to the lower surface of the rotating plate 52. The lower ends of the two elastic telescopic rods 81 are fixed with the same light-reflecting absorption ring 82. The light-reflecting absorption ring 82 is made of a high-absorption-rate composite material, with a lightweight high-temperature resistant alloy as its base material. The inner wall and the end face facing the blank are coated with a silicon carbide-graphite composite light-absorbing coating. The inner wall of the light-reflecting absorption ring 82 has an annular reflective surface 83, and the inclination angle of the annular reflective surface 83 is 45°. The tilt angle design can precisely adapt to the diffusion path of reflected light during laser cutting, achieving efficient guidance and absorption of reflected laser light. The elastic telescopic rod 81 includes a sleeve 811 fixedly set on the lower surface of the rotating plate 52. A moving rod 812 is slidably provided at the lower end of the sleeve 811. The lower end of the moving rod 812 is fixedly connected to the side wall of the reflected light absorption ring 82, and a spring 813 is fixedly provided between the upper end of the moving rod 812 and the inner wall of the sleeve 811. When the reflected light absorption ring 82 contacts the blank, the moving rod 812 moves into the inside of the sleeve 811 and compresses the spring 813, thereby giving the reflected light absorption ring 82 an elastic buffer function and avoiding excessive contact force between the reflected light absorption ring 82 and the blank.

[0036] A smoke extraction mechanism 9 is located between the light reflection absorption mechanism 8 and the rotary laser cutting mechanism 5, and the smoke extraction mechanism 9 treats the smoke generated during cutting based on the light reflection absorption mechanism 8. The smoke extraction mechanism 9 includes a smoke extraction shell 91 fixedly mounted on the upper surface of the rotary plate 52. Inside the smoke extraction shell 91, from top to bottom, a cooling plate 92, a suction fan 93, and a multi-stage filter screen 94 are fixedly mounted. A smoke extraction tube 95 is fixedly mounted on the bottom side wall of the smoke extraction shell 91. The smoke extraction tube 95 is a flexible hose, which ensures that the light reflection absorption ring 82 can move up and down without obstruction, and the reflected light... The absorption ring 82 has a hollow structure, and the inner annular reflective surface 83 of the light-reflecting ring 82 has multiple evenly distributed smoke holes 96. The end of the smoke pipe 95 away from the smoke shell 91 is fixedly connected to the light-reflecting absorption ring 82, and the smoke pipe 95 is connected to the light-reflecting absorption ring 82. When the suction fan 93 is running, a stable negative pressure environment will be formed inside the smoke pipe 95 and inside the light-reflecting absorption ring 82. With the help of the suction generated by the negative pressure, the smoke in the cutting area is quickly sucked in through the multiple smoke holes 96 preset on the inner wall of the light-reflecting absorption ring 82.

[0037] A heat dissipation mechanism 10 is disposed on the side wall of the fumigation mechanism 9, and the air outlet of the heat dissipation mechanism 10 extends to the bottom of the cutting tray 7. The heat dissipation mechanism 10 includes an air outlet pipe 101 fixedly disposed on the top of the side wall of the fumigation shell 91. The air outlet pipe 101 is a flexible hose to ensure that the vertical movement of the fumigation shell 91 is not obstructed. A hollow air outlet plate 102 is fixedly disposed at the end of the air outlet pipe 101 away from the fumigation shell 91. The hollow air outlet plate 102 is located below the cutting tray 7 and the hollow air outlet plate... Multiple evenly distributed vent holes 103 are provided on the upper surface of the hollow vent plate 102. Low-temperature gas is transported to the interior of the hollow vent plate 102 through the vent pipe 101. After entering the cavity of the hollow vent plate 102, the gas is evenly blown onto the lower surface of the cutting tray 7 through the multiple vent holes 103. A first connecting rod 104 is fixedly provided on one side of the hollow vent plate 102. A slider 105 is fixedly provided at the end of the first connecting rod 104 away from the hollow vent plate 102. The circumferential wall of the cutting tray 7 is provided with... A groove 106 is provided to cooperate with the slider 105. A second connecting rod 107 is fixedly provided on the side wall of the slider 105. An L-shaped sleeve 108 extending downward is fixedly provided on one side of the rotating plate 52. The upper end of the second connecting rod 107 is slidably connected to the lower end of the L-shaped sleeve 108. When the rotating plate 52 rotates, it will drive the L-shaped sleeve 108 to rotate synchronously. As the L-shaped sleeve 108 rotates, the second connecting rod 107 will push the slider 105 at its end to slide smoothly in the annular groove 106 preset on the circumferential wall of the cutting tray 7. A first connecting rod 104 is fixedly connected to the bottom of the slider 105. The other end of the first connecting rod 104 is connected to the hollow air vent plate 102. Therefore, when the slider 105 slides, it will drive the hollow air vent plate 102 to move synchronously along the annular trajectory through the first connecting rod 104. At the same time, the L-shaped sleeve 108 and the second connecting rod 107 are slidably connected, so that when the rotating plate 52 moves up and down, it will not drive the hollow air vent plate 102 to move up and down synchronously.

[0038] The PLC controller 11 is fixedly installed at one corner of the top of the base 1. The cylinder 3, the rotary laser cutting mechanism 5, the light reflection absorption mechanism 8, and the smoke extraction mechanism 9 are all electrically connected to the PLC controller 11.

[0039] The operating principle of the present invention is described as follows: The operator first places the blank to be processed stably on the upper surface of the cutting tray 7. In order to avoid displacement of the blank due to vibration and rotation during the cutting process, the blank needs to be fixed by the clamping fixture preset on the edge of the upper surface of the cutting tray 7. The clamping fixture adopts a conventional structure of screw and clamping plate (since this type of clamping component is widely used in the field of machining, it is not shown separately in the figure for the sake of simplifying the schematic diagram). During the fixing process, it is necessary to ensure that the geometric center of the blank is precisely aligned with the output shaft center of the motor 51, so as to provide a basic guarantee for the coaxiality of the subsequent ring cutting. After the fixing is completed, the operator turns on the main power of the entire cutting device, so that the device enters the standby state.

[0040] Subsequently, the staff manually operated the PLC controller 11 to send a start command to the cylinder 3. After receiving the signal, the cylinder 3's moving end drove the connected mounting plate 4, motor 51, rotating plate 52, and laser cutting head 53 fixed on the lower surface of the rotating plate 52 to move downwards as a whole. During the downward movement, the light-absorbing ring 82 on the lower surface of the rotating plate 52 will preferentially contact the upper surface of the blank. The light-absorbing ring 82 is made of a high-absorption composite material, and its base material is a lightweight high-temperature resistant alloy. The inner wall and the end face facing the blank are coated with a silicon carbide-graphite composite light-absorbing coating. This type of coating can absorb incident reflected light through the micro-pore structure and the optical properties of the material itself. Light energy is converted into heat energy and rapidly conducted and diffused, preventing the reflected light from escaping directly. At the same time, the light-absorbing ring 82 and the rotating plate 52 are connected by two elastic telescopic rods 81. When the light-absorbing ring 82 comes into contact with the blank, the external force generated by the contact will act on the elastic telescopic rods 81, causing the elastic telescopic rods 81 to compress axially. The rebound force of the elastic telescopic rods 81 keeps the light-absorbing ring 82 in close contact with the upper surface of the blank. The annular reflective surface 83 inside the light-absorbing ring 82 corresponds exactly to the cutting path of the laser cutting head 53, which neither blocks the laser beam nor obstructs the area that may generate reflected light during the cutting process.

[0041] Once the laser cutting head 53 has moved down to the preset cutting distance from the blank, the PLC controller 11 will automatically trigger the start commands of the motor 51 and the laser cutting head 53 according to the preset program. When the motor 51 is running, its output shaft drives the rotating plate 52 to rotate at a constant speed around its own axis, and the laser cutting head 53, which is fixed on the lower surface of the rotating plate 52, also rotates synchronously. At the same time, the laser cutting head 53 starts and emits a high-energy laser beam. The beam is precisely focused on the cutting area of ​​the blank inside the reflective light absorption ring 82, and begins to perform ring-shaped cutting on the blank. During the cutting process, since the blank is often made of metals with high reflectivity such as aluminum alloy and copper alloy, part of the laser beam will... When reflection occurs on the surface of the blank, the light absorption ring 82 surrounding the outer edge of the cutting area plays a crucial role. The silicon carbide-graphite composite coating on its inner wall can not only directly capture the reflected light beam that diffuses outward, but also convert the absorbed light energy into heat energy and release it slowly through the heat conduction structure inside the coating. This avoids the reflected light from damaging the optical components (such as focusing lens and protective lens) of the laser cutting head 53, while reducing the waste of effective cutting energy. The laser cutting head 53 continues to rotate under the stable drive of the motor 51, and completes the complete cutting of the blank along the preset circular trajectory. The entire process is greatly weakened by the interference of reflected light, and the laser energy utilization rate is significantly improved, thereby effectively improving the cutting efficiency of the blank.

[0042] During the process of the laser cutting head 53 rotating and cutting around the blank, the PLC controller 11 automatically starts the suction fan 93. When the suction fan 93 is running, it creates a stable negative pressure environment inside the smoke extraction pipe 95 and the reflective light absorption ring 82. With the suction force generated by the negative pressure, the smoke from the cutting area is quickly sucked in through multiple smoke extraction holes 96 pre-set on the inner wall of the reflective light absorption ring 82. Since these smoke extraction holes 96 are evenly distributed on the annular reflective surface 83 of the reflective light absorption ring 82 and the openings face the core area of ​​the cutting path, they can accurately capture the metal smoke and dust generated during the cutting process, preventing the smoke from spreading to the surroundings or adhering to the surface of the optical components of the laser cutting head 53, ensuring a clear cutting field of view. The sucked-in smoke enters the smoke extraction shell 91 along the smoke extraction pipe 95. Inside the smoke extraction shell 91, it is processed by a multi-stage filter screen 94 and a cooling plate 92. The multi-stage filter screen 94... The system employs a layered design, consisting of a primary filter, a secondary filter, and a high-efficiency filter from bottom to top. The primary filter is a metal woven mesh structure, primarily used to intercept larger metal slag and dust particles in the smoke, preventing large impurities from clogging subsequent filters. The secondary filter is a composite fiber filter, which uses the porous structure of the fibers to perform secondary filtration of fine dust, further purifying the smoke. The high-efficiency filter uses HEPA filter material, capable of capturing micron-sized ultrafine dust and some harmful aerosols in the smoke, reducing pollutant content. Through the multi-stage filtration, solid impurities in the smoke are effectively trapped, and the filtered gas continues to flow upwards, entering the area where the cooling plate 92 is located. The cooling plate 92 integrates a micro-cooling chip and heat dissipation fins. After being powered on, it can quickly form a low-temperature working surface, achieving gas cooling and preventing high-temperature gas from being directly discharged and causing environmental impact or thermal damage to subsequent airflow channels.

[0043] The cooled and purified low-temperature gas is transported through the exhaust pipe 101 at the top of the smoke shell 91 to the interior of the hollow exhaust plate 102. The hollow exhaust plate 102 has multiple evenly distributed exhaust holes 103 on the side facing the cutting tray 7. After entering the cavity of the hollow exhaust plate 102, the gas is evenly blown onto the annular heat dissipation groove 12 on the surface of the cutting tray 7 through the multiple exhaust holes 103. An annular heat dissipation mesh 13 is laid at the bottom of the annular heat dissipation groove 12. This annular heat dissipation mesh 13 is made of a high-temperature resistant and breathable metal mesh material, ensuring that the low-temperature gas blown from the exhaust holes 103 can smoothly penetrate the mesh and evenly cover the entire annular heat dissipation groove 12. Since the cutting part of the blank is precisely aligned vertically with the position of the annular heat dissipation groove 12... After the low-temperature gas is blown into the heat dissipation tank, it will directly act on the bottom cutting area of ​​the blank, quickly removing the heat accumulated during the cutting process and effectively suppressing the softening and deformation of the cutting part due to high temperature. At the same time, this upward gas flow direction is coordinated with the direction of the suction fan 93 drawing smoke from the upper smoke hole 96. The downward-flowing gas can generate an upward boosting force on the smoke. Combined with the negative pressure suction of the upper smoke hole 96, a "downward push and upward suction" airflow circulation is formed, which significantly accelerates the smoke extraction efficiency. During this process, the gas flow rate is gentle and the intensity of smoke extraction is within a reasonable range, which will not significantly interfere with the stability of the laser beam emitted by the laser cutting head 53, ensuring that the cutting accuracy is not affected.

[0044] When the laser cutting head 53 is driven by the motor 51 to rotate and cut around the center of the blank, it will simultaneously drive the L-shaped sleeve 108 on one side of the rotating plate 52 to rotate. The lower end of the L-shaped sleeve 108 is connected to a second connecting rod 107. As the L-shaped sleeve 108 rotates, the second connecting rod 107 will push the slider 105 at its end to slide smoothly in the annular groove 106 preset on the circumferential wall of the cutting tray 7. The bottom of the slider 105 is fixedly connected to a first connecting rod 104, and the other end of the first connecting rod 104 is connected to the hollow air outlet plate 102. Therefore, when the slider 105 slides, it will drive the hollow air outlet plate 102 to move synchronously along the circular trajectory through the first connecting rod 104. This linkage structure enables the hollow air outlet plate 102 to always follow the rotation trajectory of the laser cutting head 53, ensuring that the low temperature gas blown out from the air outlet 103 continuously and accurately acts on the current cutting part, avoiding blind spots in heat dissipation due to changes in the cutting position, thereby providing stable and efficient heat dissipation support for the entire circular cutting process of the sealed blank, and further improving the cutting quality and yield of the sealed blank.
