[0002] Valves are widely used in people's daily lives. A valve is a mechanical device used to control parameters such as fluid flow, pressure, and direction. With the development of automation technology, valve scoring devices have emerged. The scoring on a valve usually refers to the marking lines on the valve, which are used to indicate the degree of valve opening. In actual work, in order to better control the flow, it is necessary to accurately control the degree of valve opening. Therefore, it is necessary to score lines on the valve to indicate the degree of valve opening.

[0003] Existing marking devices select appropriate fixtures based on the size and shape of the valve and install them on the marking device. The valve to be marked is placed on the fixture, and the position and angle of the fixture are adjusted to align it with the cutting tool. According to the size of the fixture and the valve, the distance and angle between the cutting tool and the fixture are adjusted to the optimal position, and marking begins. The mechanical marking device is activated, so that the cutting tool cuts the valve surface in a rotating or translating manner, thereby realizing the marking operation on the valve.

[0004] The aforementioned marking device still has some problems. During the operation, different tools may be used for marking, and the marking tools need to be rotated. The existing marking device cannot flexibly switch tools, which makes it impossible to quickly mark the valve. Moreover, the tool changing process is complicated, which affects the marking efficiency. Therefore, a valve marking device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 As shown, a valve scoring device includes a base 1, a hydraulic rod 2 is installed at the top edge of the base 1, a horizontal plate 3 is fixed at the top of the actuating rod of the hydraulic rod 2, a groove 4 is opened at one end of the horizontal plate 3, a slide rod 5 is slidably installed in the groove 4, a push plate 6 is fixed at the top side of the slide rod 5, and fastening bolts 7 are respectively provided at both ends of the push plate 6.

[0025] A U-shaped frame 8 is fixedly installed on the bottom side of the slide rod 5. A rotating shaft 9 runs horizontally through the U-shaped frame 8. A worm gear 10 is rotatably installed at one end of the rotating shaft 9. A fixing plate 11 is installed on one side of the U-shaped frame 8. A drive motor 12 is mounted on one side of the fixing plate 11. A worm gear 13 is rotatably connected to the output shaft of the drive motor 12, and the worm gear 10 and the worm gear 13 mesh with each other. A turntable 14 is installed on the circumferential surface of the rotating shaft 9. The turntable 14 is located inside the U-shaped frame 8. Several small motors 15 are evenly distributed on the outer wall of the turntable 14. A scoring knife 16 is rotatably connected to the output end of the small motors 15. During operation, in actual work, in order to better control the flow rate, it is necessary to accurately control the opening degree of the valve. Therefore, it is necessary to score lines on the valve to indicate the opening degree of the valve. The push plate 6 moves, causing the slide rod 5 to move within the slide groove 4. The slide rod 5 then moves the U-shaped frame 8 until it is positioned directly above the valve that needs to be processed and fixed. The push plate 6 is then fixed to the horizontal plate 3 using the fastening bolts 7. The drive motor 12 is started, causing the worm gear 13 to rotate. The rotation of the worm gear 13 then drives the worm wheel 10 to rotate, which in turn drives the rotating shaft 9 to rotate. The rotating shaft 9 then drives the turntable 14 to rotate. After the turntable 14 rotates, the required scoring tool 16 can be rotated to be positioned directly above the valve. The small motor 15 is started, causing the scoring tool 16 to rotate and perform scoring operations on the valve. The scoring tool 16 can be flexibly replaced, allowing for multi-faceted scoring operations, thereby achieving better scoring results and improving scoring efficiency.

[0026] Furthermore, a support plate 17 is installed at the end of the hydraulic rod 2, an electrode 20 is installed on the bottom side of the support plate 17, a support seat 18 is installed on the outer wall of the bottom end of the hydraulic rod 2, a scale limiting rod 19 is fixed on the top side of the support seat 18, a through hole is opened at one end of the support plate 17, one end of the scale limiting rod 19 is disposed through the through hole, a limiting ring 21 is movably sleeved on the circumferential wall of the scale limiting rod 19, an electric plate 22 is installed on the top side of the limiting ring 21, and a locking screw 23 is fixed on the outer wall of the limiting ring 21; during operation, as... With the development of automation technology, valve scoring devices have emerged. According to the required scoring depth, the position of the moving limit ring 21 on the scale limit rod 19 is adjusted, and the limit ring 21 is fixed by the locking screw 23. The hydraulic rod 2 is opened, and the action rod of the hydraulic rod 2 shortens, which will drive the support plate 17 to move downward. The electrode 20, the electric plate 22 and the hydraulic rod 2 are electrically connected. When the electrode 20 contacts the electric plate 22, the hydraulic rod 2 stops shortening. At this time, the scoring knife 16 also fits the valve to the required scoring depth, avoiding over-scorching or under-scorching, and improving the scoring accuracy.

[0027] Furthermore, a dust collection box 24 is fixedly installed on one side wall of the base 1. A fan 25 is installed on one side of the dust collection box 24, and a filter screen 26 is installed inside the dust collection box 24. A dust suction hood 27 is connected to the other side of the dust collection box 24. During operation, waste debris will inevitably be generated during the valve's scoring process. By starting the fan 25, the rotation of the fan 25 will drive the impeller to rotate, thereby generating a strong negative pressure area. This allows air to be drawn in sequentially to form an airflow. The waste debris carried in the airflow can enter the dust collection box 24 through the dust suction hood 27, be filtered by the filter screen 26, and fall into the dust collection box 24 for collection. This process reduces dust and allows for centralized treatment of the generated waste debris, preventing environmental pollution.

[0028] Furthermore, a vertical plate 28 is fixed to the top side of one end of the base 1, a slide rail 29 is provided at the center of the base 1, a slider 30 is slidably installed in the slide rail 29, a shelf 31 is fixed to the top side of the slider 30, and a vertical plate 32 is fixed to the top side of the other end of the base 1. A first motor 33 is assembled on one side of the vertical plate 32, and a threaded rod 34 is rotatably connected to the output shaft of the first motor 33. A screw hole is provided inside the bottom end of the shelf 31, and one end of the threaded rod 34 passes through the screw hole. During operation, to prevent the valve from shifting during the scoring process, the valve to be processed is first placed on the platform 31. By starting the first motor 33, the output end of the first motor 33 rotates, driving the threaded rod 34 to rotate. As the threaded rod 34 rotates, it can also drive the platform 31 to move. When the platform 31 moves, it drives the slider 30 to move within the slide rail 29 until one end of the valve is tightly fitted with the vertical plate 28, thus completing the clamping and fixing of the valve. This allows for better scoring operations and improves scoring efficiency.

[0029] The working principle is as follows: First, the valve to be processed is placed on the platform 31. Then, the first motor 33 is started, and its output rotates, driving the threaded rod 34 to rotate. Simultaneously, the threaded rod 34 moves the platform 31, causing it to move. As the platform 31 moves, the slider 30 moves within the slide rail 29 until one end of the valve is tightly fitted against the vertical plate 28, thus clamping and fixing the valve. This allows for better scoring and improves scoring efficiency. Moving the push plate 6 moves the slide rod 5 within the slide groove 4. The movement will cause the U-shaped frame 8 to move until it is directly above the valve that needs to be processed and fixed. The push plate 6 is then fixed to the horizontal plate 3 using the fastening bolts 7. Starting the drive motor 12 rotates the worm gear 13, which in turn rotates the worm wheel 10, thereby rotating the rotating shaft 9. The rotating shaft 9 then rotates the turntable 14. After the turntable 14 rotates, the required scoring tool 16 can be rotated to directly above the valve, allowing for flexible replacement of the scoring tool 16 and enabling multi-faceted scoring operations to achieve better results. To improve the engraving effect and efficiency, the position of the moving limit ring 21 on the scale limit rod 19 is adjusted according to the required engraving depth. The limit ring 21 is then fixed by the locking screw 23. The hydraulic rod 2 is activated, causing its actuating rod to shorten, which in turn moves the support plate 17 downwards. The electrode 20, the electrode plate 22, and the hydraulic rod 2 are electrically connected. When the electrode 20 contacts the electrode plate 22, the hydraulic rod 2 stops shortening. At this point, the engraving tool 16 also fits to the required engraving depth on the valve, preventing over- or under-engraving and improving engraving accuracy. This is achieved by starting the small... Motor 15, a small motor 15, rotates to drive the scoring blade 16 to perform scoring operations on the valve. During the scoring operation, waste debris is inevitably generated. By starting the fan 25, the fan 25 rotates and drives the impeller to rotate, thereby generating a strong negative pressure area, which allows air to be drawn in sequentially to form an airflow. The waste debris carried in the airflow can enter the dust collection box 24 through the dust suction hood 27, and after being filtered by the filter screen 26, it falls into the dust collection box 24 for collection. The generated dust is treated to reduce dust, and the generated waste debris can be centrally processed to prevent waste debris from polluting the environment.
