[0012] The present invention provides a metal elbow surface grinding device, which has the following beneficial effects: 1. The surface grinding device for metal bent pipes can adjust the position of the fixing mechanism according to the curvature of the bent pipe through an adjustable fixing component, so as to achieve fixed grinding of bent pipes with different curvatures. At the same time, a clamping plate mechanism with a rubber layer on the surface is used to achieve fixed grinding of bent pipes with different diameters within a certain size range, and reduce the deformation of the bent pipe surface caused by the clamp, thereby helping to improve the grinding quality of the bent pipe.

[0013] 2. The metal pipe bending surface grinding device uses multiple sets of laser grinding components to simultaneously irradiate the surface of the metal pipe bending with multiple sets of laser beams to remove oxides and rust on the metal surface, while reducing additional damage to the surface of the metal pipe. The vibration generated by laser grinding during the grinding process is small, which delays the occurrence of reduced device reliability due to vibration impact under the condition of long-term use of the device.

[0014] 3. The metal elbow surface grinding device uses a cleaning component that uses vibration and airflow to clean impurities, and uses vibration to assist in cleaning impurities on the surface of the metal elbow before and after grinding. At the same time, it uses vibration to reduce the residual stress on the surface of the metal elbow after grinding, thereby improving the quality of the metal elbow surface. A blower is used in conjunction with a brush plate to clean the surface of the metal elbow after grinding, which promotes cooling of the surface of the metal elbow after laser grinding, thereby improving the grinding effect while improving the cleanliness of the metal elbow surface and reducing the workload of later cleaning.

[0015] 4. The metal elbow surface grinding device cooperates with the cleaning component and the fixed component. When the vibration generated during grinding is transmitted to the fixed component, a part of the vibration is offset by slight rotation between the frame and the rotating shaft, and between the rotating shaft and the slide seat, thereby reducing the shaking amplitude of the fixed structure, improving the stability of laser grinding, reducing the probability of structural looseness of the device due to long-term use, and improving the reliability of the device and the grinding quality.

The front of the frame 237 is connected with a rectangular through groove. The vertical slide tube 231 is located at the bottom of the rectangular through groove of the frame 237. The interior of the vertical slide tube 231 is a hollow structure. The top of the vertical slide tube 231 is fixedly connected to a limited position. There are four vertical slide tubes 231, two in a group, and one group is symmetrically distributed at the bottom of the rectangular slot of the frame 237, and the other group is symmetrically distributed at the top of the rectangular slot of the frame 237.

The top of the vertical clamp 232 is an arc-shaped concave surface, and the arc-shaped concave surface at the top of the vertical clamp 232 is covered with a rubber layer to reduce the direct squeezing of the clamp on the metal elbow. The bottom foot of the vertical clamp 232 is fixedly connected to the spring, and the other end of the spring is fixedly connected to the bottom of the rectangular through slot of the frame 237.

[0021] When in use, the metal bent pipe is pushed into the device from the rotating seat 23 near the back section. At this time, one end of the metal bent pipe will touch the surface of the roller 236. While the roller 236 rotates, the roller 236 drives the vertical clamp 232 and the horizontal clamp 234 to slide. The vertical clamp 232 and the horizontal clamp 234 slide while squeezing the spring until the surface of the metal bent pipe contacts the arc-shaped concave surface of the vertical clamp 232 and the horizontal clamp 234.

[0022] For example 2, please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: A grinding assembly 3 is fixedly connected to one side of the rotating seat 23. The grinding assembly 3 is fixedly connected to one side of the rotating seat 23 located at the middle position. The grinding assembly 3 includes a side mounting plate 31, a bottom mounting plate 32, a servo motor 33, a controller 34, and a laser 35. The side mounting plate 31 is fixedly connected to one side of the rotating seat 23, and the other side of the side mounting plate 31 is fixedly connected to a servo motor 33, and the back of the servo motor 33 is rotatably connected to a laser 35.

There are two circular through holes, one of which has a diameter consistent with the top cross-sectional circle of the rotating shaft 22, and the other is located at the back of the frame 237. The top of the bottom mounting plate 32 is fixedly connected to the bottom of the frame 237, and the bottom mounting plate 32 is rotatably connected to the surface of the rotating shaft 22 through the circular through hole.

In the group located on the surface of the bottom mounting plate 32, the controller 34 is fixedly connected to the bottom of the bottom mounting plate 32, and the servo motor 33 is fixedly connected to the top of the bottom mounting plate 32. In the group located on the surface of the upper mounting plate 42, the controller 34 is fixedly connected to the top of the upper mounting plate 42, and the servo motor 33 is fixedly connected to the bottom of the upper mounting plate 42. The controller 34 is electrically connected to the external power distribution system. A cleaning component 4 is fixedly connected to the top of the bottom box 11, and the cleaning component 4 includes a fan bracket 41, an upper mounting plate 42, a vibration kit 43, a compensator 44, a blower 45, and a brush plate 46. The fan bracket 41 is fixedly connected to the top of the bottom box 11. There are two fan brackets 41 and they are symmetrically distributed on the top of the bottom box 11. A circular through hole is connected to the top of the upper mounting plate 42, and the circular through hole is located on the back side of the frame 237. A limiting slide plate 421 is fixedly connected to the top of the upper mounting plate 42 to prevent the vibrator 432 of the vibration kit 43 from rotating. There are two limiting slide plates 421 and they are symmetrically distributed on the top of the upper mounting plate 42. The top of the fan bracket 41 is connected to the blower 45 to inhale external cold air and blow it out, thereby cleaning. The surface of the metal outer tube is treated and cooled. There are two blowers 45, which are electrically connected to the power distribution system outside the device. The top of the upper mounting plate 42 is connected to a vibration kit 43 for generating vibration and transmitting it to the surface of the metal outer tube to remove impurities on the surface of the metal outer tube. The top of the bottom mounting plate 32 is connected to a compensator 44, which is used to absorb the vibration transmitted from the vibration kit 43 to the bottom of the frame 237, thereby reducing the influence of the vibration kit 43 on the device itself.

[0023] When in use, the power distribution equipment connected to the device is started, the servo motor 33, the controller 34, the laser 35, and the blower 45 are started, the controller 34 controls the servo motor 33 to drive the laser 35 to rotate within a certain angle range, and at the same time controls the laser 35 to emit a laser beam to the surface of the metal bend pipe, and the oxides and rust and other impurities on the surface of the metal bend pipe absorb the energy of the laser beam and become loose, thereby separating from the surface of the metal bend pipe, and the surface of the metal bend pipe is polished; While starting the laser 35, the metal bend continues to be pushed forward. When the metal bend passes under the blower 45, the high-speed airflow blown by the blower 45 cleans the loose impurities on the surface of the metal bend. At the same time, the high-speed airflow cools the surface of the metal bend irradiated by the laser beam, thereby reducing the probability of the metal bend reacting with oxygen in the air under high temperature conditions. The metal bend continues to be pushed forward. When the metal bend passes through the rotating seat 23 located on the front side, the surface of the metal bend passes through the brush sleeve 46. The brush inside the brush sleeve 46 scrapes off the residual impurities on the surface of the metal bend to complete further cleaning. When one end of the metal bend leaves the rotating seat 23 located on the front side, the metal bend is dragged from this end to continue moving until the entire grinding process is completed.

[0024] For example 3, please refer to Figure 1-9 Based on the first and second embodiments, the present invention provides a technical solution: The vibration kit 43 includes a sliding column 431, a vibrator 432, and a pressing plate 433. The upper mounting plate 42 is connected to the sliding column 431 through a circular through hole. The bottom of the sliding column 431 is fixedly connected to the pressing plate 433 for contacting the surface of the metal elbow to transmit vibration. The top of the sliding column 431 is fixedly connected to the vibrator 432. The vibrator 432 includes a motor and an eccentric wheel fixedly connected to the motor shaft. The motor drives the eccentric wheel to rotate to generate centrifugal vibration. One side of the vibrator 432 is slidably connected to the other side of the limiting slide plate 421. The vibrator 432 is connected to the external power distribution system through a wire. A spring is slidably connected to the surface of the sliding column 431. The top of the spring is fixedly connected to the bottom of the upper mounting plate 42. The bottom of the spring is fixedly connected to the top of the pressing plate 433. The surface of the compensator 44 is slidably connected to the circular through hole in the back direction of the swivel seat 23. The bottom of the compensator 44 is fixedly connected to the limiting plate. The top of the compensator 44 is fixedly connected to a rubber cylindrical block. The surface of the compensator 44 is slidably connected to a spring. The top of the spring is fixedly connected to the bottom of the rubber cylindrical block.

[0025] When in use, while the power distribution equipment outside the device supplies power to the device, the vibrator 432 is powered on and started, and the vibrator 432 starts the motor to drive the eccentric wheel to rotate, generating vibration, which is transmitted to the pressing plate 433 through the sliding column 431, and then transmitted to the surface of the metal elbow by the pressing plate 433. In the unpolished part, some impurities on the surface of the metal elbow gradually loosen after absorbing the continuously transmitted vibration, and some impurities are separated from the surface of the metal elbow, which assists the grinding and removal of the laser beam; In the polished part, some impurities that have not been completely detached after absorbing the energy of the laser beam are detached from the surface of the metal elbow under the influence of vibration, further improving the cleaning strength of the metal elbow surface; Part of the vibration transmitted to the bottom surface of the metal elbow is absorbed by the rubber cylindrical block and the spring of the compensator 44 when passing through the rubber cylindrical block on the top of the compensator 44, thereby reducing the impact of the vibration generated by the vibration kit 43 on the device itself. Part of the vibration is transmitted to the fixed component 2. After the fixed component 2 absorbs the vibration, a relative slight rotation occurs between the rotating seat 23 and the rotating shaft 22, and between the rotating shaft 22 and the sliding seat 21, which offsets part of the vibration and prevents the vibration from causing the metal elbow to have an excessive amplitude that affects the polishing quality of the laser beam emitted by the laser 35.
